Melamine-induced adrenal structural and functional alterations and the contribution of morin to the adrenal repair in Wistar rats.

Melamine is a prevalent environmental toxicant associated with well-established toxicity on several organs. The adrenal gland is a highly dynamic organ that makes it susceptible to chemicals' toxicity. The current work investigated the adrenal histo-biochemical alterations caused by melamine exposure in rats and explored whether morin has protective potential against such adrenal toxicity.

Gold nanoparticles mediate suppression of angiogenesis and breast cancer growth via MMP-9/NF-κB/mTOR and PD-L1/PD-1 signaling: integrative in vitro validation and network pharmacology insights.

Gold nanoparticles (AuNPs) have emerged as promising candidates for cancer therapy due to their unique physicochemical properties and biocompatibility. In this study, we investigate the synthesis, characterization, and therapeutic potential of AuNPs in breast cancer treatment. Further, it establishes a comprehensive understanding of the mechanisms by which AuNPs suppress angiogenesis and breast cancer growth, identifying novel targets and signaling nodes contributing to the anti-tumor effects of AuNPs.

Assessing multi-target antiviral and antioxidant activities of natural compounds against SARS-CoV-2: an integrated in vitro and in silico study.

There is an urgent need for preventive and therapeutic drugs to effectively treat and prevent viral diseases from resurfacing as they emerge during the COVID-19 pandemic. This study aims to assess the antiviral effects of four natural compounds commonly used in traditional medicine to treat SARS-CoV-2 infection. A cytotoxicity, dose-dependent, and plaque reduction assay was performed on Vero CCL-81 cells to figure out their effects on the cells.

Assessment of myco-fabricated AlO NPs toxicity on cancer cells and pathogenic microbes by suppression of bacterial metabolic key enzymes.

There has been a recent change in global attention towards addressing antimicrobial resistance (AMR) as a result of the concerning increase in mortality rates. Nanomaterials have become highly favorable options for a wide range of industrial and biological uses. The objective of this study was to produce aluminum oxide nanoparticles (AlO NPs) using a crude extract from the fungus Aspergillus sp.

Aerobic exercise as a non-pharmacological intervention for improving metabolic and hemodynamic profiles in type 2 diabetes.

Background: Type 2 Diabetes Mellitus (T2DM) is a global health concern associated with numerous complications. Aerobic exercise is recognized as a crucial non-pharmacological intervention for T2DM management, but its specific effects on key health parameters warrant further investigation.

Objective: This study aimed to evaluate the impact of a structured 8-week aerobic exercise program on fasting blood glucose (FBG), glycated haemoglobin (HbA1c), body mass index (BMI), blood pressure (BP), and resting heart rate (RHR) in individuals with T2DM.

Cadmium exposure and its association with oxidative stress, MT1A methylation, and idiopathic male infertility in Egypt: A case-control study.

Idiopathic male infertility, a significant health concern, lacks a clear etiology. Cadmium (Cd), a widespread environmental pollutant known to impact male reproductive health negatively, can accumulate in mussels, a common food source in Egypt. This study investigated the link between ecological Cd exposure, oxidative stress, MT1A methylation, and idiopathic male infertility in two regions of Alexandria.

Interrogating the estrogen-mediated regulation of adrenocortical Klotho expression using ovariectomized albino rat model exposed to repeated restraint stress.

Reproductive aging is associated with altered stress response and many other menopausal symptoms. Little is known about the adrenal expression of the anti-aging protein Klotho or how it is modulated by estrogen in ovariectomized stressed rats. Fifty-six Wistar female rats were assigned into seven equal groups.

Probiotic-derived silver nanoparticles target mTOR/MMP-9/BCL-2/dependent AMPK activation for hepatic cancer treatment.

Recent advances in nanotechnology have offered novel ways to combat cancer. By utilizing the reducing capabilities of Lactobacillus acidophilus, silver nanoparticles (AgNPs) are synthesized. The anti-cancer properties of AgNPs have been demonstrated in previous studies against several cancer cell lines; it has been hypothesized that these compounds might inhibit AMPK/mTOR signalling and BCL-2 expression.

Ammonia scavenger and glutamine synthetase inhibitors cocktail in targeting mTOR/β-catenin and MMP-14 for nitrogen homeostasis and liver cancer.

The glutamine synthetase (GS) facilitates cancer cell growth by catalyzing de novo glutamine synthesis. This enzyme removes ammonia waste from the liver following the urea cycle. Since cancer development is associated with dysregulated urea cycles, there has been no investigation of GS's role in ammonia clearance.

Novel phloretin-based combinations targeting glucose metabolism in hepatocellular carcinoma through GLUT2/PEPCK axis of action: in silico molecular modelling and in vivo studies.

Hepatocellular carcinoma (HCC) is commonly associated with disturbances in glucose metabolism and enhanced glycolysis. However, a controversial role for gluconeogenesis was reported to be tumor-promoting and tumor-suppressive. We investigated novel anti-HCC treatments through either the simultaneous inhibition of glycolysis and gluconeogenesis by "phloretin" and "sodium meta-arsenite", respectively (Combination 1); or the concurrent inhibition of glycolysis and induction of gluconeogenesis by phloretin and dexamethasone, respectively, (combination 2).

ACE2/ACE imbalance mediates bisphenol A-induced lung injury in Wistar rats: Results from captopril versus losartan histo-biochemical study.

Bisphenol-A (BPA) is a synthetic chemical compound broadly used in the plastic and epoxy resin industries with a considerable potential for food contamination. Literary reports have suggested that the altered renin-angiotensin system (RAS) is a mechanism for lung injury and inflammation caused by variable agents. The current study sought to investigate the contribution of RAS to BPA-induced lung damage.

Rosmarinic acid mitigates chlorpyrifos-induced oxidative stress, inflammation, and kidney injury in rats by modulating SIRT1 and Nrf2/HO-1 signaling.

Chlorpyrifos (CPF) is a widely used broad-spectrum pesticide with multi-organ toxic effects. Oxidative stress was found to play a role in the deleterious effects of CPF, including nephrotoxicity. This study investigated the protective effect of the antioxidant polyphenol rosmarinic acid (RA) against CPF-induced kidney injury, with an emphasis on oxidative injury, inflammation, SIRT1, and Nrf2/HO-1 signaling.
