Structural, elastic, electronic, magnetic and thermal properties of XFeO (X = mg, ca and Sr) materials.

This prediction evaluates the different physical characteristics of magnetic materials XFeO (X = Mg, Ca and Sr) by using density functional theory (DFT). The generalized gradient approximation (GGA) approach is chosen to define the exchange and correlation potential. The structural study of the compounds XFeO (X = Mg, Ca and Sr) shows that the ferromagnetic phase is the more stable ground state, where all the parameters of the network are given at equilibrium.

Natural products can be potential inhibitors of metalloproteinase II from to intervene colorectal cancer.

, a gram negative and obligate anaerobe bacterium, is a member of normal gut microbiota and facilitates many essential roles being performed in human body in normal circumstances specifically in Gastrointestinal or GI tract. Sometimes, due to genetics, epigenetics, and environmental factors, and their protein(s) start interacting with intestinal epithelium thus damaging the lining leading to colorectal cancers (CRC). To identify these protein(s), we incorporated a novel subtractive proteomics approach in the study.

Acute, High Dose Metformin Therapy at Reperfusion Decreases Infarct Size in the High-Risk Aging Heart.

Elderly patients (age > 75) sustain larger infarcts with greater mortality from ST elevation myocardial infarcts (STEMI) despite successful reperfusion treatment. Elderly age remains an independent risk despite correction for clinical and angiographic variables. The elderly represent a high-risk population and may benefit from treatment in addition to reperfusion alone.

COVID-19: Modeling Out-of-Home and In-Home Activity Participation during the Pandemic.

Understanding the interaction between in-home and out-of-home activity participation decisions is important, particularly at a time when opportunities for out-of-home activities such as shopping, entertainment, and so forth are limited because of the COVID-19 pandemic. The travel restrictions imposed as a result of the pandemic have had a massive impact on out-of-home activities and have changed in-home activities as well. This study investigates in-home and out-of-home activity participation during the COVID-19 pandemic.

Discovering Potential Bacteriocins Against Pseudomonas fragi: a Subtractive Proteomics and Molecular Dynamic Simulation Study for Food Preservation.

Food preservation is a schematic and scientific procedure employed for the maintenance and improvement of food's quality, shelf life, and nutritional value. Although, on one hand, ancient conventional methods such as freezing, pasteurization, canning, and chemical methods have the potential to lengthen the shelf life of edible substances, but on the other hand, they can deteriorate its nutritional value as well. Present research focuses on the identification of promising bacteriocins against Pseudomonas fragi via subtractive proteomics pipeline as an alternative approach for food preservation.

Administration of metformin rescues age-related vulnerability to ischemic insults through mitochondrial energy metabolism.

Ischemic heart disease (IHD) is the leading cause of death on a global scale. Despite significant advances in the reperfusion treatment of acute myocardial infarction, there is still a significant early mortality rate among the elderly, as angioplasty-achieved reperfusion can exacerbate myocardial damage, leading to severe ischemia/reperfusion (I/R) injury and induce fatal arrhythmias. Mitochondria are a key mediator of ischemic insults; a transient blockade of the electron transport chain (ETC) at complex I during reperfusion can reduce myocardial infarct caused by ischemic insults.

Sestrin2 Mediates Metformin Rescued the Age-Related Cardiac Dysfunctions of Cardiorenal Syndrome Type 3.

Acute kidney injury (AKI) leads to acute cardiac injury and dysfunction in cardiorenal syndrome Type 3 (CRS3) through oxidative stress (OS). The stress-inducible Sestrin2 (Sesn2) protein reduces reactive oxygen species (ROS) accumulation and activates AMP-dependent protein kinase (AMPK) to regulate cellular metabolism and energetics during OS. Sesn2 levels and its protective effects decline in the aged heart.

and evaluations of actinomycin Xand actinomycin D as potent anti-tuberculosis agents.

Background: Multidrug-resistant tuberculosis (MDR-TB) is one of the world's most devastating contagious diseases and is caused by the MDR- (MDR-Mtb) bacteria. It is therefore essential to identify novel anti-TB drug candidates and target proteins to treat MDR-TB. Here, and studies were used to investigate the anti-TB potential of two newly sourced actinomycins, actinomycin-X (act-X) and actinomycin-D (act-D), from the strain UKAQ_23 (isolated from the Jubail industrial city of Saudi Arabia).

Cardiomyocyte Pdk4 response is associated with metabolic maladaptation in aging.

Ischemic heart disease (IHD) is the leading cause of death, with age range being the primary factor for development. The mechanisms by which aging increases vulnerability to ischemic insult are not well understood. We aim to use single-cell RNA sequencing to discover transcriptional differences in various cell types between aged and young mice, which may contribute to aged-related vulnerability to ischemic insult.
