Abstract

Cysteine synthase A (CysK) is an enzyme that catalyzes synthesis of L-cysteine from O-acetyl-L-serine and sulfide (primarily hydrogen sulfide) with PLP as cofactor. While its primary role in cysteine biosynthesis and sulfur assimilation is important for living organisms this enzyme also has potential secondary (or moonlighting) functions such as regulation of various gene expression by binding to DNA or RNA, cellular signaling by varying cysteine levels, or even affecting apoptosis and its pathways by differentiating in cysteine levels which is needed for glutathione synthesis necessary for protection from apoptosis induced by oxidation stress. One such CysK was found in Limosilactobacillus reuteri LR1 where it was expressed only in response to Klebsiella pneumoniae presence.

In this work, the recombinant enzyme CysK from L. reuteri LR1 (the strain was kindly provided by the All-Russian Dairy Research Institute (VNIMI)) was obtained and its various properties were studied. The enzymatic activity of this CysK was studied using several different methods such as spectrophotometry and hydrophilic interactions liquid chromatography (HILIC) and the results were compared. Using the most efficient of these methods, kinetics and stability of this enzyme were also studied. Catalytically important amino acid residues were described using the model structure of this enzyme which was compared to other known structures of CysK from different organisms.

Abstract

Medicinal plants in particular have been used in traditional medicine since antiquity to maintain holistic health and have provided preventive and curative medicines in infectious conditions. Medicinal plants are rich in a wide variety of secondary metabolites such as tannins, terpenoids, alkaloids, and flavonoids, which are known to have immunomodulatory, antioxidant, antimicrobial, anti-diabetic and anticancer properties.The emergence of new infectious diseases, the resurgence of several infections that appeared to have been controlled and the increase in bacterial resistance have created the necessity for studies directed towards the development of new antimicrobials. Considering the failure to acquire new molecules with antimicrobial properties from microorganisms, there is a shift in focus: looking novel compounds showing antimicrobial activity in some exotic plants.

Title: Expression optimization of the recombinant peptidase M23 from Limosilactobacillus reuteri LR1

Leonid Shaposhnikov

Biography

Leonid Shaposhnikov graduated from the Chemistry Department of
Lomonosov Moscow State University, Moscow, Russia in 2019 and received
his PhD in Chemistry in 2024. From 2021 he worked at the Department of

studying enzymes from various organisms for medicinal or
biotechnological purposes. The main research results were published in
journals indexed in Scopus and WoS and included in Q1 (Journal of
chromatography A, International Journal of Molecular Sciences,
Biomolecules).

Abstract

Metaloendopeptidase M23 of Limosilactobacillus reuteri LR1 belongs to the superfamily of metaloendopeptidases. These enzymes catalyze the cleavage of peptidoglycan and cleave either the N-acylmuramoyl-Ala bond between the cell wall peptidoglycan and the cross-linking peptide or a bond within the cross-linking peptide preferring the poly-Gly in this peptide making them preferably cleave gram-positive bacteria. These peptidases usually use Zn ions for catalysis. It was found that M23 peptidase is expressed in Limosilactobacillus reuteri LR1 due to presence of other microorganisms. This enzyme could be important for designing new antimicrobial agents especially against gram-positive pathogenic bacteria such as Staphylococcus aureus or Streptococcus pneumoniae.

In this work we obtained recombinant M23 from L. reuteri LR1 (the strain was kindly provided by the All-Russian Dairy Research Institute (VNIMI)). We studied expression levels of this enzyme in E. coli and optimized it by removing signal peptide coding sequence from the enzyme’s sequence. After the optimization of this enzyme’s expression in E. coli it is now possible to obtain M23 in bigger quantities and use it as potential antibacterial agent. We’ve also completed preliminary test on non-pathogenic gram-positive bacteria such as B. megaterium and shown that M23 causes lysis of these bacteria.

Abstract

The chemistry of indolizine derivatives holds great promise for the development of potential new drugs. Both natural and synthetic indolizines have demonstrated a diverse range of pharmaceutical properties, from antitumour and antimycobacterial to antagonistic and antiproliferative activities. The discovery and strategic planning of new building blocks for the synthesis of potential indolizine compounds represents a significant breakthrough in improving and optimizing the chemical production of existing drugs. The multistep synthesis of indolizine derivatives was proposed and carried out based on Eugene Babaev's studies on the use of 2-halogenpyridinium salts. The synthesis included a modified method of benzyl bromide addition without the use of solvents, SNVin reaction with diverse symmetric and asymmetric C-nucleophiles (CH-acids) and intermolecular cyclisation by Thorpe-Ziegler. The synthesis of aryl and vinyl derivatives resulted in high yields, as confirmed and described by NMR 1H, 13C, LC-MS data and reported in our recent publication. Finally, we have developed and systematised an efficient method for synthesising potential new indolizine building blocks for further application in medicinal chemistry and cutting-edge drug design.

Title: Lactococcus Lactis as a Promising Factory to Express & Characterize Membrane Proteins

Annie Frelet-Barrand

Biography

Dr. Annie FRELET-BARRAND studied biochemistry at the University of Franche-Comté (France) and was graduated as MS in 1998. In 2006, she received her PhD degree on membrane proteins (MP) characterization at the Institute of Plant Biology, Zurich. During her postdoctoral fellowship (CEA Grenoble, France), she developed L. lactis system for functional characterization of MPs. In 2009, she became CNRS Researcher at CEA Saclay, studying MPs involved in liver detoxification. In 2015, she integrated the Institute FEMTO-ST and is now producing and characterizing by biological, biochemical and biophysical techniques diverse (nano)biological elements from MPs, vesicles to bacteria and mammalian cells. She published 33 research articles including 4 book chapters (h=16).

Abstract

Membrane proteins (MPs) perform a wide variety of functions vital to the survival of organisms. Involved in numerous pathologies, they are important drug targets. In spite of their functional and biotechnological importance, their study remains difficult due to their hydrophobicity and low abundance in cells. Their overexpression in heterologous systems is mandatory for their detailed structural and functional characterization. However, this strategy leads to numerous obstacles such as their toxicity to hosts and the quality of the MP produced in these systems, especially for structural studies.

The antimicrobial peptide nisin is commonly used to control pathogenic microorganisms in dairy foods and presents anti-cancer properties and, at sub inhibiting concentrations, through the NICE (Nisin Controlled gene Expression) system for expression of proteins, either soluble or membrane of diverse origins and functions.

Using this tightly controlled gene expression system, in the last twenty years, more than 100 MPs were expressed allowing either their functional and/or structural characterization [1,2]. Recently, one eukaryotic membrane protein was expressed at a relatively high expression yield and allowed the formation of intracellular vesicles [3].

In conclusion, L. lactis represents a promising and interesting system for expression of functional proteins, including MPs. This system could be used in the future for expression of MPs of pharmaceutical interest and for biotechnological purposes.

Abstract

In the pharmaceutical industry every product and every process associated with risks. To maintain product quality throughout the product life cycle, too much time and resources are allocated. Risk is described in - recent guidance as a combination of the probability of occurrence of harm and the severity of that harm. The Quality Risk Management (QRM) approach initiated by regulatory agencies with recognized management tools along with support of statistic al tools in combination allows for a risk-based approach to quality management, thus ensuring that resources are deployed in a timely and expeditious manner to areas that need them most.

QRM improves risk awareness and accelerates detection of potential issues by analyzing and comparing existing data from a quality perspective to manage product quality, manufacturing processes, validation and compliance within a risk based Quality Management System. In addition quality risk management improves decision making if a quality problem arises. It should include systemic processes designated to co-ordinate, facilitate and improve science-based decision-making with respect to risk.

Title: Investigation of the Tribological Properties of Cartilage-on-Cartilage and Cartilage-on-Glass Under Different Liquid Lubricants

Haytam Kasem

Biography

Haytam Kasem received his master’s degree in mechanical engineering from the University of Haute Alsace, Mulhouse, France, in 2004. He received his Ph.D. degree in tribology of composite materials from the University of Orleans, France, in 2008. He joined the Tribology Laboratory at Technion, Israel, in 2012 and the Azrieli College of Engineering Jerusalem (JCE), Israel, in 2013. His current positions are Associate Professor, Head of the Department of Mechanical Engineering, and Head of the Tribology and Microstructure Laboratory at the JCE. His research areas cover the tribology of bionic microstructures, biotribology, mechano?chemical surface treatment, and the tribology of friction brakes.

Abstract

Any future development of new artificial lubricants for osteoarthritis treatment necessities full characterization of lubrication properties in terms of boundary lubrication joint, mobility, and frictional behavior. However, tribology has not yet been integrated with the clinical reality of worn particles present in synovial fluid and their impact on osteoarthritic joints. Part of the problem relates to the tribological approach adopted to study friction by applying inadequate testing methods such as pion-on-disc or block-on-ring testers. Furthermore, most of the studies reported in the literature so fare consider biological cartilage sample rubbing against a smooth and hard counterface, such as glass, covered with the lubricant liquid. This configuration suffers of lack of imitation of physiological conditions of biological joints.

To bridge the gap, in the present study synovial fluid containing, or not, worn particles was studied using a customized test-rig (tribometer). This device enables the contact to be open at the end of each friction cycle and to simulate hence more closely the natural knee joint contact conditions. Moreover, friction tests are performed with cartilage-on-cartilage configuration and the outcome results are compared to those obtained with the classical cartilage-on-glass configuration.

Results show clearly that opening the contact at the end of each friction cycle enables the lubricant to re-cover the rubbing surfaces, which allows to better illustrate the effect of the worn particles present in the lubricant. In addition, cartilage-on-cartilage configuration leads to lower but more irregular friction compared with that of cartilage-on-glass configuration tested under the same lubricants and experimental conditions

You have proposed for the commercial batch in the 2000L S.E blender having same blending and lubricating times of 10 minutes and 5 minutes respectively as that of 750L S.E Blender used for the exhibit batch. This is very unusual. Though for diffusion type mixer moving to a larger blender the same number of revolutions will be required. However, the blend time would increase due to the fact the larger the blender, the slower the vessel rotates.  Please justify your rationale for having same mixing time between these two blenders. Also please provide the rotational speed (rpm) for the 2000L S.E. Blender You used 30 station Fette tablet press for the compression of exhibit batch tablets and proposed to use a 49 station Fette Tablet press for the commercial batch.  Please provide your comparative press speed to maintain their same dwell time from scale-up perspective

Title: Complexities and Potential of Multimodel Resins to Overcome protein Purification Challenges.

Maryam Moazami

Biography


Abstract

Increasing attention has been paid to the purity of therapeutic proteins imposing extensive costs and challenges to the downstream processing of biopharmaceuticals. One of the efforts, that has been exerted to overcome such limitations, was developing multimodal or mixed-mode chromatography (MMC) resins. However, protein adsorption-desorption in mixed-mode resins becomes complicated due to several interactions with the ligand’s functional groups.  In this work, the explanation of practical and key aspects of downstream processing of recombinant proteins with or without MMC resins will be debated. Then, after complete elucidation of the potential of MMC resins, the effects of frequently used additives and their possible interactions during the purification process, the critical characteristics of common product-related, host-related, and process-related impurities will be discussed.  Due to such complexities, the design of experiment (DOE) will be introduced as a suitable tool for developing a meticulous optimization process in protein purification using multimodal resins.

Title: SOD1 is a Druggable Target in Platinum-Resistant Ovarian Cancer

Attila Szenasi

Biography

Dr. Szenasi is a postdoctoral research associate at the University of North Carolina at Chapel Hill, Lineberger Comprehensive Cancer Center, specializing in chemotherapy resistance in luminal breast cancer. He earned his Ph.D. in Biological Sciences from the University of Liverpool, focusing on therapeutic approaches to reverse platinum-resistant ovarian cancer. He holds an MBA in Entrepreneurship and Innovation from the University of London and an MSc in Nanomedicine from Swansea University. Dr. Szénási has extensive experience in medicine, nanomedicine, and translational drug development, with a strong background in collaborative research and innovation.

Abstract

Acquired platinum resistance poses a significant therapeutic impediment to ovarian cancer patient care, accounting for more than 200,000 deaths annually worldwide. We previously identified that overexpression of the antioxidant superoxide dismutase 1 (SOD1) in ovarian cancer is associated with a platinum-resistant phenotype via conferring oxidative stress resistance against platinum compounds. We further demonstrated that enzymatic inhibition using small-molecule inhibitors or silencing of SOD1 via RNA interference (RNAi) increased cisplatin sensitivity and potency in vitro. We launched this study to explore the potential therapeutic applications of SOD1 silencing in vivo in order to reverse cisplatin resistance using a graphene-based siRNA delivery platform. PEGylated graphene oxide (GO) polyethyleneimine (GOPEI-mPEG) nanoparticle was complexed with SOD1 siRNA. (Figure 1) GOPEI-mPEG-siSOD1 exhibited high biocompatibility, siRNA loading capacity, and serum stability, and showed potent downregulation of SOD1 mRNA and protein levels. We further observed that cisplatin and PEI elicited mitochondrial dysfunction and transcriptionally activated the mitochondrial unfolded protein response (UPRmt) used as a reporter for their respective cytotoxicities. SOD1 silencing was found to augment cisplatin-induced cytotoxicity resulting in considerable tumour growth inhibition in cisplatin-sensitive A2780 and cisplatin-resistant A2780DDP subcutaneous mouse xenografts. Our study highlights the potential therapeutic applicability of RNAi-mediated targeting of SOD1 as a chemosensitizer for platinum-resistant ovarian cancers.

Abstract

Recently, multi-drug resistant (MDR) bacteria are responsible for a large number of infectious diseases that can be life-threatening. Globally, new approaches are targeted to solve this essential issue. This study aims to discover novel antibiotic alternatives by using the whole components of the biofilm layer as a macromolecule to synthesize silver nanoparticles (AgNPs) as a promising agent against MDR. In particular, the biosynthesized biofilm-AgNPs were characterized using UV-Vis spectroscopy, electron microscopes, Energy Dispersive X-ray (EDX), zeta sizer, and potential while their effect on bacterial strains, and normal cell lines was identified. Accordingly, biofilm-AgNPs have a lavender-colored solution, spherical shape, with a size range of 20–60 nm. Notably, they have inhibitory effects when used on various bacterial strains with concentrations ranging between 12.5 and 25 µg/mL. In addition, they have an effective synergistic effect when combined with phage ZCSE9 to inhibit and kill Salmonella enterica with a concentration of 3.1 µg/mL. In conclusion, this work presents a novel biosynthesis preparation of AgNPs using biofilm for antibacterial purposes to reduce the possible toxicity by reducing the MICs using phage ZCSE9.

Title: Paracetamol is the Most Unscientific and Dangerous Drug for Fever. Anyone Can Create a Fever Within Hours Using Antipyretic Objects.

Yacob Mathai

Biography

He is a practicing physician in the field of healthcare in the state of Kerala in India for the last 36 years and very much interested in basic research. His interest is spread across the fever, inflammation and back pain. He is a writer. He already printed and published Ten books on these subjects. He also wrote hundreds of articles in various magazines.  have published 11 articles on fever in various journals.

Abstract

Depletion of ProstaglandinE2 and glutathione, which reduces inflammation, can also increase inflammation. These fundamental errors have led to the treatment of fever with antipyretic agents. No such treatment or science was found even in the Stone Age.


No other illness or symptom is more unscientific than justifying the administration of paracetamol for fever. There is no one percent evidence that paracetamol increases blood flow by reducing inflammation and helping the immune system in any way. At the same time, there is 100% evidence that paracetamol increases inflammation, reduces blood flow and destroys the immune system.


Prescribing paracetamol for fever is murderous as it depletes substances such as prostaglandin E2 and glutathione which increase blood flow and sustain life.
