Senescence landscape in the liver following sepsis and senolytics as potential therapeutics.

Senescence, caused by cell-cycle arrest, is a hallmark of aging. Senescence has also been described in embryogenesis, wound healing, and acute injuries. Sepsis is characterized by a dysregulated host response to infection, leading to organ dysfunction and mortality.

p53 dependence of senescence markers p21v1 and p21v2 in aging and acute injury.

The senescence phenotype is heterogeneous, as observed by the context-dependent differential expression of senescence markers. Here, we provide evidence to demonstrate an inverse relationship in the expression pattern of the two murine variants of p21 (p21v1, and p21v2) in aging and hemorrhagic shock. While an upregulation of p21v1 was observed following hemorrhagic shock injury, p21v2 was upregulated in the aged mouse.

Permeation of individual cryoprotectants and their different combinations into mouse liver tissue.

Development of successful tissue cryopreservation methods requires specific knowledge regarding tissue permeation of individual cryoprotective agents (CPAs) and their combinations. The present study assessed the permeation of dimethyl sulfoxide, ethylene glycol, and propylene glycol into liver tissue, and addressed whether the diffusion coefficient of individual CPAs changes when combining CPAs. To do this, mouse liver slices were exposed at room temperature to 3.

Characterization of NiONPs synthesized by aqueous extract of orange fruit waste and assessed their antimicrobial and antioxidant potential.

This research was performed to evaluate the nickel oxide nanoparticles (NiONPs) fabricating potential of orange fruit waste (OFW) aqueous extract. Moreover characterize the synthesized OFW-NiONPs through standard techniques such as UV-vis. spectrophotometer, Fourier-transform infrared spectroscopy (FTIR), dynamic light scattering (DLS) and Scanning Electron Microscope (SEM) analyses.

Larvicidal and pupicidal activity of phyto-synthesized zinc oxide nanoparticles against dengue vector aedes aegypti.

This study aimed to assess the phyto-synthesizing potential of Tarenna asiatica methanol leaf extract as well as its larvicidal and pupicidal potential against Aedes aegypti larvae. According to the findings of this study, the methanol leaf extract of T. asiatica has the potential to synthesize zinc oxide nanoparticles from zinc acetate dehydrate.

Insights from the analysis of predicted Rv0679c protein peptide from Mycobacterium tuberculosis with Toll like Receptors in host.

Peptides of Rv0679c a membrane protein of the cell envelope (16.6 KDa) of Mycobacterium tuberculosis (M. tb), inhibited entry of live bacilli into epithelial (A549) and macrophage (U937) cell lines in vitro, suggesting a possible role in invasion.
