Integrated Multi-omics, Virtual Screening and Molecular Docking Analysis of Methicillin-Resistant < em > Staphylococcus aureus < /em > USA300 for the Identification of Potential Therapeutic Targets: An In-Silico Approach
In this study, staphylococcal FemA protein (P0A0A5) is subjected to structure-based virtual screening for the drug repurposing approach. There are 20 residues missing in the crystal structure of FemA, and 12 of these residues are located at the catalytic site. The missing residues are modelled, and stereochemistry is checked. FDA approved drugs available in the DrugBank database have been used in virtual screening with FemA in search of potential repurposed molecules. This approach provides us with 10 drugs that may be used in the treatment of methicillin-resistant staphylococcal mediated diseases. AutoDock 4.2 is used for...

Association of COVID-19 With Major Arterial and Venous Thrombotic Diseases: A Population-Wide Cohort Study of 48 Million Adults in England and Wales
CONCLUSIONS: High relative incidence of vascular events soon after COVID-19 diagnosis declines more rapidly for arterial thromboses than VTEs. However, incidence remains elevated up to 49 weeks after COVID-19 diagnosis. These results support policies to prevent severe COVID-19 by means of COVID-19 vaccines, early review after discharge, risk factor control, and use of secondary preventive agents in high-risk patients.PMID:36121907 | DOI:10.1161/CIRCULATIONAHA.122.060785

A Look Back at 2022: Progress Towards the Treatment of Aging as a Medical Condition
At the end of 2022, we can reflect on the fact that we are steadily entering a new era of medicine, one in which mechanisms of aging are targeted rather than ignored. It is a profound change, one that will change the shape of a human life and ultimately the human condition by eliminating the greatest sources of suffering and death in the world. Year after year, we see increased funding, ongoing progress towards therapies capable of slowing aging or reversing aspects of aging, and a growing taxonomy of such potential therapies and their target mechanisms. The view of aging in the medical community and public at large...

Bad news: The influence of news coverage and Google searches on Gardasil adverse event reporting.
CONCLUSION: The results suggest that some of the adverse events reported were not related to the vaccination itself, but to news coverage and internet search volumes, which may have contributed to public concerns about potentially unpleasant or harmful outcomes. These findings have implications for the importance of psychological and social factors in adverse event reporting, and the role of the news media in disseminating health information.

Tumor-Associated Lymphatic Vessel Features and Immunomodulatory Functions
Laure Garnier*, Anastasia-Olga Gkountidi and Stephanie Hugues* Department of Pathology and Immunology, Faculty of Medicine, University of Geneva, Geneva, Switzerland The lymphatic system comprises a network of lymphoid tissues and vessels that drains the extracellular compartment of most tissues. During tumor development, lymphatic endothelial cells (LECs) substantially expand in response to VEGFR-3 engagement by VEGF-C produced in the tumor microenvironment, a process known as tumor-associated lymphangiogenesis. Lymphatic drainage from the tumor to the draining lymph nodes consequently increases, powering inters...

A Co-expression Analysis of the Placental Transcriptome in Association With Maternal Pre-pregnancy BMI and Newborn Birth Weight
Conclusion Using a co-expression approach, we identified pivotal placental gene clusters that may shed new light on the molecular link between maternal and offspring metabolic health. Interestingly, this study indicated genes involved in immune defense and erythrocyte-related hub genes to be upregulated in association with maternal pre-pregnancy BMI and downregulated in association with low birth weight. Moreover, modules enriched for developmental, vascular, and extracellular matrix-related genes were positively correlated with maternal BMI and birth weight. Given the critical role of the placenta in regulating gestation...

In conclusion, the study indicates that HBOT may induce significant senolytic effects that include significantly increasing telomere length and clearance of senescent cells in the aging populations. Data on the Prevalence of Liver Fibrosis in Middle Age https://www.fightaging.org/archives/2020/11/data-on-the-prevalence-of-liver-fibrosis-in-middle-age/ Fibrosis is a consequence of age-related disarray in tissue maintenance processes, leading to the deposition of scar-like collagen that disrupts tissue structure and function. It is an ultimately fatal issue for which there are only poor treatment options a...

This study showed that the leakage of this mitochondrial nucleic material may occur as a result of mitochondrial dysfunction, which may involve genetic mutations in genes encoding mitochondrial proteins or incomplete degradation of mitochondrial dsDNA in the lysosome - which is a 'degradation factory' of the cell. Upon the leakage into the cytoplasm, this undegraded dsDNA is detected by a 'foreign' DNA sensor of the cytoplasm (IFI16) which then triggers the upregulation of mRNAs encoding for inflammatory proteins." Using a PD zebrafish model (gba mutant), the researchers demonstrated that a combination of PD-like ph...

This study showed that centenarians had very specific changes in CD4+ T cell populations, which were manifested by an elevated Th17/Treg ratio in vivo, as well as a changed secretory phenotype. Although the T cells of centenarians cannot resist the aging-related expression of proinflammatory genes, their secretory phenotype was altered, explaining the relatively low level of inflammation in centenarians. These results suggested the presence of a mechanism to ameliorate inflammaging in centenarians. This may be achieved by reversing the imbalance of Th17/Treg cells and reducing pro-inflammatory cytokines. Longevit...

In this study, we report the extensive and progressive accumulation of misfolded proteins during natural aging/senescence in different models, in the absence of disease. We coined the term age-ggregates to refer to this subset of proteins. Our findings demonstrate that age-ggregates exhibit the main characteristics of misfolded protein aggregates implicated in PMDs, including insolubility in detergents, protease-resistance, and staining with dyes specific for misfolded aggregates. Misfolded protein aggregates with these characteristics are thought to be implicated in some of today most prevalent diseases, including Alzheim...

In this study, we used a Drosophila model to understand the role of the dec2P384R mutation on animal health and elucidate the mechanisms driving these physiological changes. We found that the expression of the mammalian dec2P384R transgene in fly sleep neurons was sufficient to mimic the short sleep phenotype observed in mammals. Remarkably, dec2P384Rmutants lived significantly longer with improved health despite sleeping less. In particular, dec2P384R mutants were more stress resistant and displayed improved mitochondrial fitness in flight muscles. Differential gene expression analyses went on to reveal several altered tr...
