- Abstract:
The photoionization spectroscopy of free radicals is a difficult task mainly because it implies the use of efficient radical sources and of tunable VUV radiations. In this talk, I will describe two different techniques employing either the threshold photoelectron spectroscopy (TPES) coupled with synchrotron radiations or the pulsed-field-ionization zero-kinetic-electron photoelectron spectroscopy (PFI ZEKE PES) coupled with a tunable VUV laser. In the first part of the talk, I will briefly present a few results obtained in collaborations with J.C. Loison (ISM) on carbon-bearing and/or silicon-bearing radicals using a flow tube reactor coupled with the DELICIOUS 3 spectrometer of the DESIRS beamline of the SOLEIL synchrotron [1,2]. In the second part, I will introduce a laser setup that we built at ISMO to perform high-resolution PFI-ZEKE spectroscopy of free radicals [3]. Results on the CH3 radical that confirmed the recent detection of the methyl radical cation (CH3 +) in a protoplanetary disk within the Orion star-forming region [4] will be presented [5].

Passcode: 762202
- Abstract:
Fundus photography and optical coherence tomography are the gold standard of ocular imaging. Nevertheless, there are several important limitations with these technologies including limited sensitivity/specificity to detect disease, limited penetration depth,
no molecular contrast, little improvement in lateral resolution, and structural rather than functional information. There are two principal approaches.

Passcode: 488333
- Abstract:
Current AI research predominantly focuses on big data, which introduces challenges related to model explainability, limited access to extensive datasets, model complexity, the necessity for normalisation techniques, and requirements for data annotation and collection. These challenges contrast with human decision-making, which hinges on small data, explicability, and handling of uncertainty.
During the seminar, It will be introduce an AI Lifelong Learning approach that operates effectively with small data, offers explainable outcomes, and obviates the need for new data gathering or annotation. To witness the practicality of this approach, join us at the seminar where it will be demonstrated its application to a problem of interest, AMD.

Meeting ID: 931 4566 7092
Passcode: 488333
- Abstract:
Vision relies on a complex system, which comprises an optical camera and a neural processor, adjusting to match visual coding and environment. Light-based technologies have allowed further understanding of its limits and pave the way to the development of novel treatments. Phase modulation has allowed significant insights on visual science, from the optical properties of the eye, as well as the processes of neural adaptation behind them. Adaptive Optics (AO) based visual simulators are now able to couple the measurement of the aberrations with their correction or manipulation by means of different active technologies (deformable mirrors, spatial light modulators, optotunable lenses), both in monochromatic and polychromatic conditions, allowing the characterization of the chromatic aberration of the human eye and its impact on vision. The understanding of the interactions of these aberrations and their effect upon correction is essential to explore the limits of human spatial vision, and to design and optimize new alternatives of optical corrections.
Moreover, optical and structural properties of the eye change with age and with certain ocular conditions and treatments, altering the natural aberrations, their interactions, and consequently the visual function. In the last years, visual simulators have revolutionized the management of Presbyopia, the loss of the autofocus accommodation of the human eye, and its treatment. They allow mapping the phase profile of a contact lens (CL) or an intraocular lens and explore vision with those corrections prior to being fitted or implanted in the eye, and even manufactured, therefore allowing the patient to experience different corrections in a completely non‐invasive manner. In the last years, applications for Myopia management have arisen, allowing a better understanding of visual performance with MCLs in young eyes, where MCLs may be prescribed to control the progression of myopia wherein the MCLs optics interact with accommodation, and in presbyopes, where MCLs are increasingly used to compensate the lack of accommodation.

Could an active cellular metabolism stir up the cytoplasm?
Advanced lecture series - bio-inspired chemistry

- Institution: IChF Aula
- Place:
IChF Aula
- Abstract:
Cellular metabolism is a network of more than 1000 different chemical reactions, which altogether provide cells with chemical energy and building blocks for new cells. How cells direct molecules through this network is still an open question. To this end, we have found that apparently cells use this network such that their growth rate is maximized, but at the same time would not exceed a certain Gibbs energy dissipation rate. While in analogy to man-made machines, a maximal dissipation rate limit makes intuitively sense, yet the question is why and how -on the molecular level of a cell-a (too) high Gibbs energy dissipation rate could be harmful. We hypothesized that increasing Gibbs energy dissipation rate would lead to increased motion of molecules inside cells, which could be detrimental for biomolecules and their interactions. Thus, to test this, we had to start measuring motion inside cells. From here, unfortunately, things get complicated and it might still take us a few more years until we have a clearpicture. Yet, within this seminar, I still wanted to show some exciting findings on our way to understand how an active cellular metabolism could stir up the cytoplasm, hoping for a good discussion with the audience.

- Abstract:
Myopia is the most common refractive error affecting young populations today, and a significant public health concern, given its rapid rise in prevalence in recent decades. Evidence, initially from animal studies suggests an important role for the vascular choroid in the development of refractive errors. This presentation will discuss research examining the role of the human choroid in the regulation of eye growth and the development of myopia. The response of the human choroid to visual stimuli such as optical blur and light will be outlined, and the choroidal changes associated with normal eye growth and myopia development will be discussed. The choroidal response to myopia control interventions and the potential for choroidal measures to predict longer term eye growth responses will also be explored.

- Abstract:
Retinal vascular diseases are a leading cause of blindness. Optical coherence tomography (OCT) has become the standard imaging modality in clinic. OCT angiography (OCTA) has been rapidly adopted in research and clinical settings. In this talk, the development of OCTA techniques for clinical use will be introduced, the application of artificial intelligence in OCTA will be reviewed, and high-performance OCTA prototypes will be discussed. OCT oximetry is new type of functional OCT, which has recently been achieved by visible-light OCT and used in preclinical and clinical research. Altered retinal vascular oxygenation measured by OCT may benefit the research on ocular vascular biology and physiology and influence clinical diagnosis or management of retinal diseases. In this talk, the development of OCT oximetry on retinal capillaries and its applications on rodent models will be presented. At the end, the future directions of OCT angiography and oximetry will be discussed.

- Place:
Aula (in-person seminar)
- Abstract:
A computational protocol is proposed in this talk for use in discovering reaction mechanisms. The method does not rely on either chemical intuition or assumed a priori mechanisms, working in a fully automated fashion.
The pipeline consists of three steps:
1. Exploration of reaction mechanisms through Molecular Dynamics simulations or chemical knowledge-based algorithms.
2. Use of Graph Theory to build the reaction network.
3. Kinetics simulations.
The method has been successfully employed to study combustion chemistry, cycloaddition reactions, photodissociations, organometallic catalysis, radiation damage of biological systems, simulation of mass spectrometry experiments, and astrochemistry, and a few examples will be given in this talk.

- Abstract:
Optical coherence tomography has revolutionized ocular imaging, transforming the way ocular tissue can be imaged in an in vivo manner. In a similar manner, deep learning has emerged as a powerful tool disrupting the field of medical image analysis.
Lessons learned from applying deep learning techniques to ocular OCT image analysis will be covered, exploring the challenges encountered during the development and implementation of deep learning models for OCT images, including the need for large annotated datasets, model selection, and generalizability across different patient populations and imaging devices.
A number of exciting future directions in deep learning-based OCT image analysis will be highlighted, such as generative adversarial networks, that hold promise for improving the accuracy and efficiency of disease detection, segmentation, and classification tasks.
This overview of deep learning techniques should allow for a better understanding of the potential and future that these techniques can have to inform the decision-making of clinicians and researchers, and more importantly, improve patient care.

- Abstract:
Retinal vascular diseases are a leading cause of blindness. Optical coherence tomography (OCT) has become the standard imaging modality in clinic. OCT angiography (OCTA) has been rapidly adopted in research and clinical settings. In this talk, the development of OCTA techniques for clinical use will be introduced, the application of artificial intelligence in OCTA will be reviewed, and high-performance OCTA prototypes will be discussed. OCT oximetry is new type of functional OCT, which has recently been achieved by visible-light OCT and used in preclinical and clinical research. Altered retinal vascular oxygenation measured by OCT may benefit the research on ocular vascular biology and physiology and influence clinical diagnosis or management of retinal diseases. In this talk, the development of OCT oximetry on retinal capillaries and its applications on rodent models will be presented. At the end, the future directions of OCT angiography and oximetry will be discussed.

Optical microscopy plays a key role in the development of biology and biomedicine by enabling cell and tissue examination.

Phase microscopy non-invasively uses an endogenous contrast agent in the form of a phase delay introduced locally by biological samples.

Owing to their unique properties, phase microscopy methods open the possibility of studying live cell colonies. Well-established Zernike and Nomarski setups enable the qualitative examination of transparent cells with only a slight, yet pivotal, increase in contrast. Quantitative phase imaging (QPI) has emerged to empower precise diagnostics and high-contrast imaging with very low background level. Numerical reconstruction plays a key role in QPI, however, which is not the case in fluorescence imaging or classical phase microscopy. I discuss three representative techniques of QPI microscopy and the basics of how their reconstruction algorithms work: (1) digital holographic microscopy (mainly using coherent illumination), (2) Fourier ptychographic microscopy (using mainly non-coherent radiation), and (3) lensless holographic microscopy (using partially coherent light). A summary of the advantages and disadvantages of the selected quantitative phase microscopy methods presented will provide an outline of the potential development paths in the pursuit of hybrid (experimental and numerical) signal-to-noise ratio improvement in a high-speed fashion.crease in contrast.

- Abstract:
Crossing the cell membrane barrier is a critical step in many biochemical and biomedical studies. The great majority of these involve the use of biomacromolecules that are not spontaneously taken up by the cell due to the selective permeability of the cell membrane. Thus, an efficient method for delivering a desired compound into cells is required. A novel method was developed in the Institute of Physical Chemistry PAS: Cell-IN is a reagent that allows the introduction of different types of molecules inside mammalian cells quickly and simply without needing specific equipment. Cell-IN works by disintegrating intracellular vesicles under osmotic shock. During disintegration, cargo closed inside the vesicles is released into the cell. Cell-IN has been validated for a wide range of compounds (dyes, polymers, proteins, nucleic acids, nanoparticles) as well as cell types (normal, cancer, epithelial, mesenchymal cells).

Passcode: 488333
- Abstract:
Every tissue, cell, and organelle has specific electrochemical properties resulting from differences in concentrations of protons, small ions, and charged macromolecules. Delivering proteins to these different environments can trigger functionally relevant structural rearrangements, which we refer to as conformational switching. A notable example is the transition of specific soluble proteins into lipid membranes. This phenomenon is prominent in many physiological and pathogenic processes, including the regulation of apoptosis by the Bcl-2 family of proteins, critical for cancer treatment. Our ability to target or manipulate these processes can be beneficial for human health. For example, membrane insertion of the pH Low Insertion Peptide (pHLIP) has recently been used to target drugs to cancer cells. While these processes are of fundamental biomedical importance, basic knowledge of the mechanism of conformational switching is often lacking, impeding our ability to predict protein-lipid interactions under physiological conditions. Here we present our progress applying various experimental and computational approaches in deciphering complex interactions on membrane interfaces and establishing the role of lipid composition and divalent cations (i.e, Ca2+ and Mg2+) in modulating important physiological processes.

- Place:
Thursday, the 30th of March, 10:00 am, Aula (in-person seminar)
- Abstract:
The question about the uniqueness of RNA and DNA and the reasons for their selection as the only informational polymers in biology is one of the most fascinating problems for contemporary science. Despite years of experimental efforts, the first selective pathways to RNA/DNA nucleotides under prebiotic conditions were shown only recently [1,2]. However, it is still unclear why nature selected only a limited set of nucleobases and (deoxy)ribose as the primary components of nucleic acids and how these informational polymers could have undergone self-replication. In this talk, I will demonstrate how modern methods of computational chemistry can be used to explain the origins of RNA and DNA on Earth and guide futher experimental efforts. In particular, I will show how chemical selectivity could be shaped by UV irradiation in early prebiotic environments. I will also demonstrate how quantum chemical simulations can be used to enhance charge transfer through the DNA double helix with simple modifications of nucleobases [3,4].

- Abstract:
Nowadays, biomedical research is facing a series of significant problems. These include i) scientific challenges – the available in vitro and animal models are often inadequate for the recapitulation of human biology, ii) economic issues – the cost related to drug development is skyrocketing, and iii) ethical concerns – the use of animals for research purposes is perceived by the public opinion as cruel and unjust. In this context, digital manufacturing technologies represent one of the most promising solutions to address these limitations, enabling for a rapid, highly-customized manufacturing of cellularized constructs that can efficiently mimic both the structural and functional properties of native tissues/organs. Within the seminar, we will give a brief overview of the state-of-the-art in musculoskeletal tissue engineering and talk about the upcoming innovations required to shake up this area of study.

- Place:

- Abstract:
Light is ubiquitous and light-driven processes are key, e.g., to the perception of the environment by vision and photosynthesis. Furthermore, light-responsive molecules and materials play a quintessential role in addressing central socio-economic challenges, e.g., transforming our economy towards renewable energies or developing therapeutic approaches to treat cancer. Consequently, research on light-activated molecules and materials, i.e., synthesis as well as functional and mechanistic studies on such systems are intensively researched.
This talk will focus on light-driven molecular reactivity of molecules in complex environments, focusing on the excited-state dynamics in molecular intermediates in photocathodes for light-driven hydrogen evolution, in complex electron transfer cascades and photo-activated drugs for cancer therapy. I will discuss our experimental approaches, e.g., combining electrochemistry with ultrafast time-resolved spectroscopy, to investigate the light driven molecular reactivity from new viewpoints and highlight implications for photocatalysis and photodrug design obtained from the spectroscopic-mechanistic studies.
The event is obligatory to all doctoral students, and of interest, I hope, to the whole IChF community.

- Abstract:
In the past few years, organocatalysis have become a promising strategy to promote chemical reactions. However, the design of more efficient catalysts is of continuous demand. Aiming at solving some of the current reactivity and stability limitations of organocatalytic systems, our group is devoted to the design of innovative non-covalent and photoredox active structures for the development of robust metal-free synthetic methodologies. In this regard, we have recently introduced helical chiral triazoles as versatile multidentate H-donor structures that allow for challenging enantioselective transformations in anion-binding catalysis.[1,2] Their cooperative multidentate character permits the use of very low loadings (down to 0.05 mol%), while promoting an efficient transfer of chirality from the chiral contact ion-pair formed upon binding of the catalyst to a simple achiral anion to the final product. Herein, the remarkable performance of H-donor chiral triazole foldamers in the nucleophilic dearomatization of N- and O-heteroarenes (up to 99:1 e.r.) will be presented.[2,3]
Another line of research in our group deals with the design of novel acridinium salts for their application in photoredox-catalysis.[4] Hence, the synthesis, photophysical properties and application of tunable amide-acridinium structures with enhanced photoredox catalytic activity respect to the well-established C9-mesityl acridinium salts will also be discussed.[5]

- Abstract:
RPE65 retinol isomerase is an indispensable player in the visual cycle between the vertebrate retina and RPE. RPE65 is of significant medical interest as its lack in humans, due to RPE65 gene mutations, causes Leber Congenital Amaurosis (LCA), an early onset severe blindness in newborns and children. While the US FDA in 2017 approved the first successful gene therapy for an eye disease to treat LCA due to RPE65 mutations, it is quite expensive and unaffordable to many. Alternative pharmacological therapies to target retinal diseases due to lack of RPE65 are clearly needed but requires a complete understanding of RPE65’s mechanism and function. Despite a detailed understanding of RPE65 physiological function, structural understanding of RPE65-membrane interaction is still limited. While association with smooth endoplasmic reticulum (sER) membrane is necessary for catalytic function (substrate access), RPE65 lacks a membrane insertion domain. Moreover, the loop region that is believed to interact with sER is unresolved and apparently disordered in all crystal structures of RPE65. This loop contains aa107-125, a predicted amphipathic helix. We previously showed that palmitoylation of C112, within aa107-125, is partly responsible for RPE65-membrane association. In our recent work, we report the mechanism of membrane recognition and binding by RPE65. We found that binding of an aa107–125 synthetic peptide with membrane-mimicking micellar surfaces induces its transition from an unstructured loop to an amphipathic α-helical (AH) structure, but that this transition is automatic in the C112-palmitoylated peptide. We demonstrate that the AH significantly affects palmitoylation level, membrane association, and isomerization activity of RPE65. Furthermore, aa107–125 functions as a membrane sensor and the AH as a membrane-targeting motif sufficient to target heterologous proteins to liposomes or ER. Molecular dynamic simulations clearly show AH-membrane insertion, supporting our experimental findings. Collectively, these studies allow us to propose a working model for RPE65-membrane binding, and to provide a novel role for cysteine palmitoylation.

- Abstract:
Rabies virus (RV) can infect neurons via retrograde transport, from postsynaptic to presynaptic cells. RV is also an attractive candidate for gene delivery, as it can provide fast and high expression of transgenes that can be potentially used in gene therapy of degenerative diseases. Genetic modifications of the envelope glycoprotein (G) can impact the selectivity of RV infections, and such modification has been successfully applied to manipulate RV in the TVA/EnvA system. Pseudotyping of G-deleted RV (RVΔG) with chimeric protein consisting of the ectodomain of EnvA protein and the cytoplasmic domain of G protein enables to restrict initial infection with RV to cells expressing non-mammalian TVA receptor, delivered by Adeno Associated Virus (AAV) helper viral vector (F. Osakada et al., 2013). Expression of transgenes in AAV plasmids is driven by an upstream promoter that can be constitutive or cell-type specific, therefore specificity of infection can be uniquely controlled on that level (C. Domenger et al., 2019). The main goal of our projects is to use AAV vectors and RV as gene therapy tools, that specifically infect cells within the retina, to treat retinal degenerative diseases. We have managed to isolate promoters to drive the expression of transgenes in specific types of cells within the retina. Further, we demonstrated that pseudotyping of Viral Like Particles (VLPs) with chimeric G proteins enables them to infect desired cells, and this approach is going to be used for the pseudotyping of RV. Indeed, our results indicate that RV is a potential tool for effective gene therapy, as we successfully, simultaneously transduced retinal cells with up to four different transgenes. Further analysis will reveal the therapeutic effect of performed gene deliveries.

- Abstract:
Molecular recognition mechanisms during neuronal synapse formation are still incompletely understood. The neuronal transmembrane protein family of Teneurins is required for synaptic partner matching in the visual and hippocampal systems in vertebrates. It remains however unclear how individual Teneurin molecules form macromolecular cis- and trans-cellular protein complexes at the neuronal synapse. The structure reveals a compact conformation of the dimer that is stabilized by C-rich, YD-shell and ABD-mediated interactions. We identified three conserved calcium binding sites in the C-rich domain that control the compactness and stability of Teneurin4 dimers. We then use in vivo cellular assays to visualize how these compact cis dimers establish homomeric trans interactions. Together, these findings support a role for Teneurins as a scaffold for macromolecular complex assembly and the establishment of cis- and trans-synaptic interactions to construct functional neuronal circuits.

- Abstract:
Surgical tool pose estimation is important for surgical image guidance systems as near real-time tool tip position and angle estimation are needed, for example, for intraoperative optical coherence tomography tracking in retinal microsurgery. This paper presents an algorithm that improves on the current state-of-the-art algorithm for surgical tool tracking in posterior eye surgery first introduced by Alsheakhali et al. We propose better tool segmentation based on combined color space masks and set thresholds, a shadow-insensitive tool edge detector, and a more robust tool tip detector. The presented algorithms are benchmarked based on a series of manually annotated images of posterior eye surgery. Our modifications improve the algorithm’s accuracy several-fold in a posterior surgery video case study where the tool shadow has a confounding effect and spot illumination by the endoilluminator occurs at times.

One of the subcortical areas that provide input projection to visual cortex and thus influence the properties of the visual response is Basal Forebrain (BF). The Basal Forebrain is predominantly characterized by its’ cholinergic projection patterns to the visual cortex. The functional contribution of this input is only starting to become understood. We propose that cholinergic modulation coming from BF will significantly impact single neuronal responses of the primary visual cortex (V1) in Long-Evans rats. The primary goal of this project is to understand the Basal Forebrain's role in the processing of the visual information in the V1 and its effect on the visual system activity. To answer this question, we used cutting-edge techniques like viral tracing and optogenetic stimulation of neuronal circuits paired with electrophysiological recordings in the primary visual cortex. Precisely, we injected the modified Rabies virus (RV) into the V1 to retrogradely trace inputs coming from the Basal Forebrain. The RV carries opsins to allow for both activation and inhibition of infected cells in the Basal Forebrain. We hypothesize that the manipulation of the BF changes the selectivity of single cells in the V1. Indeed, our preliminary results confirm this hypothesis. The most prominent observation in our experiment is a significant change in firing rate when showing various directions of drifting gratings at optimal Spatial Frequency (SF), Temporal Frequency (TF), and Size. However, this change was different for different layers (depth) in the cortex. All layers tend to have a lower firing rate; however, the cell around layer IV tend to have an increased firing rate. Perhaps the most important result is the change in the optimal stimulus size. Most cells showed decreased optimal stimulus size, and the difference between conditions tends to be stronger in the upper layers than in the deep layers of the V1. Our preliminary results suggest that the Basal Forebrain plays a substantial role in the modulation of the center-surround interactions. These results are in line with the previous data from Lyon Lab (Lean et al., 2018), showing that the main inputs from BF are coming into the GABAergic cells in the V1.
The project is supported by the National Science Center, Poland (2020/39/D/NZ4/01881) for AT.

- Abstract:
The search for new families of materials to fulfil the wide range of requirements for energy storage in a sustainable energy system is of great importance. Inorganic imides and amides have been under-explored as functional materials aside from interest in the hydrogen storage properties of the lithium amide-lithium hydride composite. However, these materials display promising performance as catalysts for the synthesis and decomposition of ammonia. These reactions are gaining increasing interest in the context of the storage and export of large quantities of renewable energy via the electrolysis of water to produce hydrogen. Lithium imide-based materials show very promising ammonia synthesis and decomposition activity to rival that of ruthenium. The bulk variation in composition of the materials under active conditions, revealed by in situ diffraction analysis, appears to be a key aspect of their function.

- Place:

- Abstract:
Modelling still plays a minor role in the biopharmaceutical industry as compared to
the automotive and aerospace industries, for instance. Much theory has been developed
over the last decades, studying individual mechanisms and academic systems.
Industrial processes are typically more complex due to multiple components, variable
feed composition, non-linear scaling with size, and numerous other parameters.
Recent improvements in computing power, mathematical software and data availability
allow for the first time to meet these challenges by applying models of realistic
complexity. Such models can potentially help to improve process understanding,
transfer knowledge from microfluidics to production scale, speed up the process
development, and focus or even reduce experimental effort.

Meeting ID: 946 0989 6336
Passcode: 633683
- Abstract:
Mitochondria actively participate in the regulation of cell respiratory mechanisms, metabolic processes, and energy homeostasis in the central nervous system (CNS). Because of the requirement of high energy, neuronal functionality and viability are largely dependent on mitochondrial functionality. In the context of CNS disorders, disruptions of metabolic homeostasis caused by mitochondrial dysfunction lead to neuronal cell death and neuroinflammation. Therefore, restoring mitochondrial function becomes a primary therapeutic target. Recently, accumulating evidence suggests that active mitochondria are secreted into the extracellular fluid and potentially act as non-cell-autonomous signals in CNS pathophysiology. Here, we overview findings that implicate the presence of cell-free extracellular mitochondria and the critical role of intercellular mitochondrial transfer in stroke. We also discuss isolated mitochondrial transplantation as a novel therapeutic intervention and the future perspectives.

- Abstract:
Water-in-oil droplets, made and handled in microfluidic devices, provide a new experimental format in which ultrahigh throughput experiments can be conducted faster and with minimal reagent consumption. An increasing number of studies have emerged that applied this approach in single-cell assays. The seminar will cover the recent research focused on the directed evolution of enzyme biocatalysts, the efficient and functional selection of rare strains of bacteria and the development of novel droplet microfluidic technologies for profiling of single cells transcriptomes. Recent advances in single-cell RNA sequencing methodologies have massively scaled up the number of cells that can be processed in a single reaction. However, most droplet-based scRNA-seq methods utilize only a single microfluidic step of co-compartmentalization of cells with barcoded molecules, which limits the array of applications of single-cell genomics assays. Here we present novel microfluidic pico-injection and droplet sorting modules that allow for complex single-cell assays in high-throughput droplet format. We harness the unique properties of these multi-step droplet protocols to i) deliver a high-quality molecular atlas of mouse brain development using highly damaged input material, and to ii) generate the first large-scale total-RNA-seq atlas to profile mouse gastrulation and early organogenesis.

- Abstract:
Molecular photomagnets[1] can be designed and prepared via a bottom-up modular approach using low-energy preparation methods developed by coordination, organometallic or supramolecular chemistry, and crystal engineering with the support from physical and computational sciences. They belong to the class of molecule-based materials that become paramagnetic, ferromagnetic or simply change their magnetic properties upon illumination[2] - a feature hardly accessible in conventional solids - metal alloys and oxides.
Currently known photomagnetic compounds are merely laboratory curiosities due to the low operation temperatures below the boiling point of nitrogen in most cases[3]. Hence, the major goal of this field of research is the discovery of new strategies for room temperature (RT) photomagnets that would show light-induced ON/OFF ferromagnetic switching under normal conditions.

- Abstract:
The dynamics of electrolytes in narrow pores is important in various fields of science and technology. Examples range from axons firing in the brain and plant cells signalling through plasmodesmata to energy storage in supercapacitors. In the porous carbon electrodes of supercapacitors, ions move over millimetres through macropores until they arrive at nanopores, where they screen the electrode’s surface charge. In the first part of the talk, I will discuss several models for this multi-scale charging process. In particular, I will present analytical [1] and finite-element solutions [2] to the Poisson-Nernst-Planck equation for the charging of cylindrical electrolyte-filled pores. With these solutions, I will delineate the validity of the popular “transmission line” (TL) circuit model [3,4]. In the second part of the talk, I will discuss how the supercapacitors can harvest sustainable energy from temperature differences and from the salinity differences between sea and river water.

- Abstract:
Retinol binding protein 3 (RBP3) is a major component of the interphotoreceptor matrix (the space between the photoreceptor cells and the retinal pigment epithelium (RPE)) and mediates the interaction between rods, cones, RPE and Muller cells by shuttling retinoids and potentially lipids. Mammalian RBP3 is a single polypeptide having four modules, and each consists of ~300 amino acids.
In our proposed project, we will determine the structure of RBP3 protein at a high resolution to understand the role of the cooperativity mechanism and open the possibility of structure-based drug design. Along with this, we plan to use the method Small Angle X-Ray Scattering (SAXS) to get more structural information about the protein with different ligand concentrations. The cooperativity mechanism and effect of the ligands on the protein are unknown, and in this way, we can get the answer to some unsolved queries. Apart from this, there is an anti-correlation between amounts of RBP3 protein and the severity of diabetic retinopathy (DR), and this protein could be a beneficial biomarker in the field of diabetic retinopathy. The quantification, structural determination and potential monitorization of RBP3 in DR, and at an early stage, could be a ray of hope in the development of new therapeutic approaches for DR.

- Abstract:
Coherent-light Doppler imaging by digital holography - laser Doppler holography - is a technique dedicated to visualisation of blood flow. It is based on detecting optical interferograms from light backscattered from the retina beating against a separate reference beam followed by digital image rendering. Measurement of the Doppler broadening allows to quantify an instantaneous velocity of red blood cells throughout the cardiac cycle. The analysis of the shape of the pulse-wave can provide important information about the mechanical properties of the retinal vessels. The same setup can be used for complementary cornea transparency imaging and aberration measurements.

- Abstract:
Hydrogen bonding is a very important structural parameter for both chemical and biological compounds. Hydrogen bonding influences a number of chemical properties such as boiling points, solubility, pKa values etc. and the interaction between small molecules (drugs) and biomolecules. Hydrogen bonding is a determining factor in the structure of carbohydrates, proteins, DNA and RNA. The talk will discuss spectroscopic techniques such as Infra Red and NMR to establish the presence of hydrogen bondsand characterize those. A special technique, deuterium isotope effects on chemical shifts to establish the presence of hydrogen bonds will be presented and used to find hydrogen bonds and salt bridgesin proteins in solution vs. X-ray structures. Related to intramolecular hydrogen bonding is tautomerism. Tautomerism is often elusive and methods will be given to establishing this phenomenon. Examples will be taken from chemistry and biology. In the latter case, the importance of having the right structure in relation to biological action is discussed. Finally, theoretical calculations will be touched upon.

- Abstract:
Intraocular light scattering affects the contrast of the image created on the retina thus reducing the vision quality. Although generally the ocular components are transparent, the microstructural changes associated with ageing or external factors can affect intraocular light scattering. The presence of opacifications is an indicator of vision-affecting diseases such as corneal dystrophies, crystalline lens cataracts, vitreous floaters etc.
Optical coherence tomography (OCT) is a non-invasive imaging modality enabling generation of micrometer resolution, two-dimensional (2-D) cross-sectional images and three-dimensional (3-D) volumetric data presenting internal structure of optically scattering tissues. In OCT, back-scattered light can be used to visualize the structure of the eye. The advantages of this interferometric imaging modality include also high sensitivity, which enables detection of ultralow scattered light levels obtained from weakly scattering tissues such as the vitreous body.
In this talk, we will demonstrate in vivo enhanced three-dimensional visualization of vitreous and lens opacities in subjects of different ages using a swept source OCT system. We developed OCT instrument operating at the central wavelength of 1050 nm that was able to generate the cross-sectional images with axial resolution of 8 μm. Volumetric images were used to effectively map the opacities and to generate en-face projection images of opacities. The results revealed the changes in the transparency of the crystalline lens as well as liquefaction and scattering from well-organized opacified structures in the vitreous. The proposed imaging platform can be a new-generation ophthalmic diagnostic tool in the fundamental studies as well as for objective clinical evaluation and management of eye diseases.

- Abstract:
Chiral electrochemistry, including enantioselective electroanalysis and enantioselective electrosynthesis, is a quite explored area of research, but with a huge applicative potential yet to be studied.
Considering that chirality makes electrochemical processes smarter and applicable to issues of much higher added value we focused our attention on the characterization of new classes of inherently chiral materials. Inherent chirality is an intrinsic property of a molecule, propagating in the 2D and 3D space, which provides specific characteristics to the resulting material, obtained after depositing it on an electrode surface or after adding it as a chiral additive in a solution. Employing such molecules in enantioselective analysis, we have obtained for the first time a separation between the enantiomers of chiral probes (even drugs in complex matrix) in terms of peak potential values, testing racemic mixtures of the enantiomers of chiral drugs, and evaluating the enantiomeric excesses [1]. Starting from this point, by the optimization of the experimental conditions, several inherently chiral compounds with chemically different atropoisomeric scaffold and stereogenic elements, were synthetized and characterized, in order to be exploited in different fields (i.e. chiral electroanalysis, spintronics). Recently, the attractive and far unexplored potentialities of these systems, were also exploited in the field of bipolar electrochemistry, allowing to correlate a dynamic macro and microscopic event with the concentration of the enantiomers present in solution [2-5]. The efficient combination of the two approaches, the molecular static event with the macroscopic dynamic one, allowed me to be awarded with the prestigious ERC StG with the acronym “CHEIR”, a project funded by European Committee for five years. The global aim of such project is to achieve with unprecedented efficiency the propagation of chiral information along different length scales, based on the synergy of well-chosen molecular ingredients and physicochemical engineering. Such ambitious aim will be realized developing cargo-towing (synthetic) electro-pumps based on chiral conducting polymers for targeted drug-delivery applications.

- Abstract:
Interactions that occur on the cell surface have a central role in regulating many important biological processes, including, immune response, cell-cell communication, disease progression, and cell‒pathogen interactions. These processes are mediated by cell-surface glycoproteins, glycolipids, and glycopolymers, and glycans expressed in the glycocalyx are unique identifiers of cell type that can indicate disease and could serve as drug targets. For many diseases and infections, there is still a need for effective treatments that halt their progression, and molecules that can bind the glycans could be used for early detection of the disease biomarkers or as drug delivery agents, as anticancer and antiviral treatments. These needs, however, require understanding of the chemical underpinning of the protein-glycan recognition, as well as efficient and detailed methods of structural analysis of glycans.
In the first part of the lecture, I will summarize role of glycans in diseases and viral infections, and discuss the challenge associated with the design of therapeutics targeting surface glycans. Next, I will discuss the basics of chemical recognition of glycans using covalent binding, metal-assisted binding, and noncovalent interactions. Finally, I will introduce the idea of flexible synthetic carbohydrate receptors, which include cooperativity and multivalency in their binding mode, as a design that could lead to development of novel sensing devices and unlock new glycan targets for future therapeutics.
In the second part of the lecture, I will discuss recent advances in gas-phase glycoanalytics. In principle, the development of the glycomics has been hampered by the lack of both high-resolution and high-throuhtput methods to able to isolate and deduce a glycan structure. Herein, I will focus in recent developments in liquid chromatography, mass spectrometry, ion-mobility spectrometry and cryo IR spectroscopy in the context of the glycan analysis, discussing the strengths and limitations of these methods. While each of these methods has its own merits, the combination of the techniques provides a multidimensional reference library that could be used for seamless identification of complex glycans. Finally, I touch on the role of the computational chemistry in glycoanalysis, and its synergy with the gas-phase glycoanalysis.

- Abstract:
Diseases such as cancer, diabetes or viral and bacterial infections are one of the main causes of human mortality, regardless of age and origin. Perfect methods of treatment have still not been found. Much hope is placed on research into the origin of a disease, usually involving tens or hundreds of biological macromolecules called enzymes. From this point of view, one of the most important groups of enzymes are proteases, the increased or decreased level of which allows for rapid clinical diagnosis using specific markers, and also gives the opportunity for rational, rapid research on drug discovery based on protease activity. An excellent reason for research on proteases are commercially available anti-cancer, anti-diabetic and anti-viral HIV drugs that rely on the inhibition of protease activity. Unfortunately, these drugs can only be used for a limited number of diseases, and many other proteases (around 650 proteases have been described in humans to date) involved in various disorders in humans and other living organisms require further research.
Proteases are key players in the development of viral diseases. Recent studies show that proteases operate in a network that involves the activity of many different proteolytic enzymes at the same time. Given the fact that more and more proteases are actively involved in viral diseases, there is an urgent need to develop new chemical tools that, thanks to the activity of enzymes, can be used for their precise monitoring or the search for drug candidates. Moreover, in order to detect the active form of the protease, one should use chemical tools called activity-based probes. The lecture will present modern techniques of creating tools for the study of viral proteases.
The event is obligatory to all doctoral students, and of interest, I hope, to the whole IChF community.

- Abstract:
In developmental systems, cells determine their fate by decoding chemical signals, called morphogens. This leads to the emergence of gene expression patterns, whose dynamics is still not fully understood. In this presentation I will address the problem of gene expression patterns stability in the systems where two diffusible morphogens affect each other’s production and control the growth of their own source regions. Such systems are encountered in e.g. spinal cord development, limb formation and many others. The reaction-diffusion equation with the bi-stable production term is employed as a generic model for this problem. It is found that its dynamics is governed by the conservation law, which leads to a range of analytical results. In particular, the phase transition is observed, between the phase of indeterminate patterning, where region of mixed gene expression is ever-growing, and the phase of travelling gene expression patterns, where two expression domains form and preserve a well-defined contact zone. A sub-class of genuinely stationary patterns is then identified, alongside the exact conditions ensuring this stability. These results allow me to classify the ability of various two-gene regulatory motifs to produce stable gene expression patterns.

- Abstract:
Despite the vast clinical acceptance of optical coherence tomography (OCT) in visualizing the structure and vasculature system (angiography) of the retina, the method is still lacking the capability to provide molecular fingerprints of retinal tissue. The assessment of biochemical changes would critically enhance the early disease diagnostics when treatment is most effective. In recent years Raman spectroscopy (RS) has been recognized as an extremely powerful tool for bioanalytical and biomedical applications because the method provides molecular fingerprint information of the molecular structure and biochemical composition of cells and tissues without external markers. Diseases and other pathological anomalies are accompanied by changes in these properties. However, the application of spontaneous RS under in vivo conditions is extremely challenging due to the delicate nature of the eyes. The presentation will review different approaches for ocular RS and focus on the first reported spontaneous RS fingerprint spectra of the human retina in-vivo.

- Abstract:
Long-Term Memory (LTM) and Working memory (WM) interact closely, but the neuronal basis of this interaction remains poorly understood. In our previous research we discovered that stimulus-selective persistent activity of Medial Temporal Lobe (MTL) neurons supports WM maintenance. As MTL is crucial for forming new memories this persistent activity could play an important role also in LTM encoding. Indeed, the strength of the stimulus-selective activity during WM maintenance predicts whether an item is subsequently remembered in the later LTM recognition task. These results show that selective neuronal activity during WM maintenance acts as a common neural substrate for both WM maintenance and LTM formation.

- Abstract:
The discovery of electroluminescence of organic molecules is one of the ground-breaking and promising breakthroughs in the last century. Owing to it and to the progress in the field of organic electronics over the last half-century, nowadays, we are surrounded by organic light-emitting diodes (OLEDs) products. In addition to lightness, flexibility, and low production cost, the major advantage of using organic emitters for OLEDs is the possibility to tailor their properties by designing and modifying their molecular structures. From the viewpoint of emission mechanisms, there are two types of emitters: fluorescence and phosphorescence emitters. Fluorescence emitters are the first generation of electroluminescence emitters for OLEDs, but they are fatally restricted by the upper limit of internal quantum efficiency (IQE) of 25%, due to spin-statistics. The second-generation emitter, phosphorescence emitters, are more efficient and for this reason, are commonly used in OLED-based displays. However, nothing is perfect: phosphorescence emitters that are currently used in organic electronics are organometallic complexes comprising of very expensive and rare heavy metals such as Ir and Pt. To overcome this problem, the search for all-organic TADF (Thermally Activated Delayed Fluorescence) emitters is conducted.
Herein I present a new approach to the design of metal-free organic thermally activated delayed fluorescence emitters for organic light-emitting diodes. I present different aspects of modification of molecule structure in order to increase efficiency. Even by simple electrochemical modification, it’s possible to change the energy levels in order to decrease the singlet-triplet energy gap. The subtle tunning of the energy difference between the singlet and triplet excited states allows for tailored emission properties of thermally activated delayed fluorescence and its efficiency. Finally, depending on the molecule and its host environment interaction, we may change the emission and increase efficiency. All presented steps will give an insight into broad possibilities of tailoring OLED emitters.
The event is obligatory to all doctoral students, and of interest, I hope, to the whole IChF community.

- Abstract:
To provide more personalized treatment, human physiology models are becoming more and more complex and the amount of data is increasing considerably, therefore, advanced methods of modelling and data analysis are necessary.
Since 2000 DICE Team (http://dice.cyfronet.pl/) has been involved in the research focused on problem-solving environments and decision support systems on distributed computing infrastructures for medicine. The main partners were the University of Sheffield, University of Amsterdam, Juelich Supercomputing Centre, LMU and Leibniz Supercomputing Centre in Munich. As a result of successful scientific collaboration a new scientific unit: Sano Centre for Computational Personalized Medicine – International Research Foundation was established in 2019, in Krakow (https://sano.science/).
Sano Centre is a new non-profit, autonomic research institute dedicated to advancement of computational medicine, development of computer methods for the prevention, diagnosis and treatment of disease, meet the worldwide need for efficient, effective and streamlined healthcare.
Six Sano research teams cover such in-silico medicine areas as modelling and simulation, data science, artificial intelligence and machine learning methods, image processing, IT methods in medicine, large-scale computing, and decision-making support systems. This research will result in the development of tools supporting doctors in diagnostic and treatment processes. It is extremely valuable from the point of view of an individual patient and will reduce the costs of treatments. Modern computer technologies developed in Sano may also be used in pharmaceutical and biotechnology laboratories.
