Signatures of ambient pressure superconductivity in thin film LaNiO.

Recently, the bilayer nickelate LaNiO has been discovered as a new superconductor with transition temperature T near 80 K under high pressure. Despite extensive theoretical and experimental work to understand the nature of its superconductivity, the requirement of extreme pressure restricts the use of many experimental probes and limits its application potential. Here we present signatures of superconductivity in LaNiO thin films at ambient pressure, facilitated by the application of epitaxial compressive strain.

Emerging research highlights the functionality of high mobility group box-1, a non-histone nucleoprotein functioning as a chromosomal stabilizer and inflammatory mediator.

Exploration of anti-atherosclerotic activity of 1,8-cineole through network pharmacology, molecular docking, and in vivo efficacy studies in high-fat-diet-induced atherosclerosis in hamsters.

The anti-atherogenic potential of liver X receptors (LXRs) has been attributed to their inhibitory role in macrophage-mediated inflammation and promotion of reverse cholesterol transport. This study aimed to evaluate the efficacy of an LXR agonist, 1,8-cineole (Eucalyptol), in atherosclerosis through network pharmacology, molecular docking, and in vivo efficacy studies in high-fat-diet-induced atherosclerosis in hamsters. Network pharmacology analysis was performed by identifying potential targets of 1,8-Cineole and atherosclerosis, followed by the construction of component-target-disease and protein-protein interaction networks.

Ghrelin in Depression: A Promising Therapeutic Target.

Depression is a widespread disease affecting over 300 million individuals of various ethnicities and socioeconomic backgrounds globally. It frequently strikes early in life and becomes a chronic or recurring lifelong illness. Out of the various hypotheses for the pathophysiology of depression, the gut-brain axis and stress hypothesis are the ones that need to be researched, as psychological stress impairs one or more pathways of the brain-gut axis and is likely to cause brain-gut axis dysfunction and depression.

Selection of solvent and positive control concentration for enhanced Ames test conditions for N-nitrosamine compounds.

The Ames test is a widely used bacterial mutagenicity assay to evaluate the potential of chemical compounds to induce mutations. In recent years, there has been growing concern regarding the presence of N-nitrosamines in pharmaceuticals, food, and other consumer products. N-Nitrosamines are probable mutagens and carcinogens.

Valosin-containing protein: A potential therapeutic target for cardiovascular diseases.

Valosin-containing protein (VCP), also known as p97, plays a crucial role in various cellular processes, including protein degradation, endoplasmic reticulum-associated degradation, and cell cycle regulation. While extensive research has been focused on VCP's involvement in protein homeostasis and its implications in neurodegenerative diseases, emerging evidence suggests a potential link between VCP and cardiovascular health. VCP is a key regulator of mitochondrial function, and its overexpression or mutations lead to pathogenic diseases and cellular stress responses.

Targeting Adipokines: A Promising Therapeutic Strategy for Epilepsy.

Epilepsy affects 65 million people globally and causes neurobehavioral, cognitive, and psychological defects. Although research on the disease is progressing and a wide range of treatments are available, approximately 30% of people have refractory epilepsy that cannot be managed with conventional medications. This underlines the importance of further understanding the condition and exploring cutting-edge targets for treatment.

Safety Assessment of a Novel Intravenous Diclofenac Sodium Formulation Following 28-Day Repeated Administration in Wistar Rats.

These toxicity studies aimed to assess the safety and tolerability of a novel intravenous diclofenac sodium (37.5 mg/mL) formulation containing povidone K12 (80 mg/mL) as the key excipient in Wistar rats. This formulation was tested at doses of 3, 7, and 15 mg/kg/day and was administered daily for 28 days by intravenous route.

Artesunate attenuates isoprenaline induced cardiac hypertrophy in rats via SIRT1 inhibiting NF-κB activation.

Cardiac Hypertrophy is an adaptive response of the body to physiological and pathological stimuli, which increases cardiomyocyte size, thickening of cardiac muscles and progresses to heart failure. Downregulation of SIRT1 in cardiomyocytes has been linked with the pathogenesis of cardiac hypertrophy. The present study aimed to investigate the effect of Artesunate against isoprenaline induced cardiac hypertrophy in rats via SIRT1 inhibiting NF-κB activation.

PAQR4 oncogene: a novel target for cancer therapy.

Despite decades of basic and clinical research and trials of promising new therapies, cancer remains a major cause of morbidity and mortality due to the emergence of drug resistance to anticancer drugs. These resistance events have a very well-understood underlying mechanism, and their therapeutic relevance has long been recognized. Thus, drug resistance continues to be a major obstacle to providing cancer patients with the intended "cure".

Drug-resistant Mycobacterium tuberculosis among Nepalese patients at a tuberculosis referral center.

Background: Multidrug-resistant tuberculosis (MDR-TB), characterized by isoniazid and rifampicin resistance, is caused by chromosomal mutations that restrict treatment options and complicate tuberculosis management. This study sought to investigate the prevalence of pre-extensively drug-resistant (pre-XDR) and extensively drug-resistant (XDR) tuberculosis, as well as mutation pattern, in Nepalese patients with MDR/rifampicin-resistant (RR)-TB strains.

Methods: A cross-sectional study was conducted on MDR/RR-TB patients at the German Nepal Tuberculosis Project from June 2017 to June 2018.

T-cell metabolism in rheumatoid arthritis: focus on mitochondrial and lysosomal dysfunction.

Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by immune cell dysregulation, synovial hyperplasia, and progressive cartilage destruction. The loss of immunological self-tolerance against autoantigens is the crucial insult responsible for the pathogenesis of RA. These immune abnormalities are experienced many years before the onset of clinical arthritis.

Consequently, evaluating patient satisfaction and its underlying factors is crucial to maintaining the quality of healthcare services.

Enhanced Oral Bioavailability of Progesterone in Bilosome Formulation: Fabrication, Statistical Optimization, and Pharmacokinetic Study.

Progesterone, a female sex steroid hormone, is highly lipophilic, leading to poor oral bioavailability. This study aimed to develop a progesterone bilosome system to enhance its oral bioavailability and retain it longer in the body. Progesterone vesicles were formulated with bile salts by thin film hydration method to prevent enzymatic and bile acid degradation.

Absence of 3a charge density wave order in the infinite-layer nickelate NdNiO.

A hallmark of many unconventional superconductors is the presence of many-body interactions that give rise to broken-symmetry states intertwined with superconductivity. Recent resonant soft X-ray scattering experiments report commensurate 3a charge density wave order in infinite-layer nickelates, which has important implications regarding the universal interplay between charge order and superconductivity in both cuprates and nickelates. Here we present X-ray scattering and spectroscopy measurements on a series of NdNiO samples, which reveal that the signatures of charge density wave order are absent in fully reduced, single-phase NdNiO.

Transposable Elements: Emerging Therapeutic Targets in Neurodegenerative Diseases.

Neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS), are characterized by the progressive loss of neuronal function and structure. While several genetic and environmental factors have been implicated in the pathogenesis of these disorders, emerging evidence suggests that transposable elements (TEs), once considered "junk DNA," play a significant role in their development and progression. TEs are mobile genetic elements capable of moving within the genome, and their dysregulation has been associated with genomic instability, altered gene expression, and neuroinflammation.
