Background: We aimed to identify the central lifestyle, the most impactful among lifestyle factor clusters; the central health outcome, the most impactful among health outcome clusters; and the bridge lifestyle, the most strongly connected to health outcome clusters, across 29 countries to optimise resource allocation for local holistic health improvements.
Methods: From July 2020 to August 2021, we surveyed 16 461 adults across 29 countries who self-reported changes in 18 lifestyle factors and 13 health outcomes due to the pandemic. Three networks were generated by network analysis for each country: lifestyle, health outcome, and bridge networks.

Background: Tissue damage by viral hepatitis is a major cause of morbidity and mortality worldwide. Oxidation reactions and reactive oxygen species (ROS) transform proteins and lipids in plasma low-density lipoproteins (LDL) into the abnormal oxidized LDL (ox-LDL). Hepatitis C virus (HCV) infection induces oxidative/nitrosative stress from multiple sources, including the inducible nitric oxide synthase (iNOS), the mitochondrial electron transport chain, hepatocyte NAD(P)H oxidases (NOX enzymes), and inflammation.

The main goal of the current study is to estimate the in vivo anti-inflammatory/antioxidant ability of four selected pharmaceutical compounds: bisoprolol (Biso), piracetam (Pirc), clopidogrel (Clop), and cinnarizine (Cinna). Indomethacin (Indo) was used as a reference drug to perform a realistic comparison between the four compounds and the Indo in vivo through tracking PI3K/AKT signaling and computational chemistry via density functional theory (DFT) modeling to analyze the electrostatic potential across the molecule and provide insight into the regions for receptor binding of the studied compounds. To achieve the safe dose of these compounds, cytotoxicity was performed against isolated adipose tissue-derived mesenchymal stem cells (ADMSCs) using MTT assay.

Biosynthesized nanoparticles have a variety of applications, and microorganisms are considered one of the most ideal sources for the synthesis of green nanoparticles. Icerya aegyptiaca (Douglas) is a pest that has many generations per year and can affect 123 plant species from 49 families by absorbing sap from bark, forming honeydew, causing sooty mold, and attracting invasive ant species, leading to significant agricultural losses. The purpose of this work was to synthesize titanium dioxide nanoparticles (TiO-NPs) from marine actinobacteria and evaluate their insecticidal effects on Icerya aegyptiaca (Hemiptera: Monophlebidae), in addition to explaining their effects on protein electrophoresis analysis of SDS‒PAGE proteins from control and treated insects after 24, 72 and 120 h of exposure.

Excessive irrigation of saline-alkaline soils with Cd-contaminated wastewater has resulted in deterioration of both soil and plant quality. To an investigate this, a study was conducted to explore the effects of biochar (applied at 10 t ha), PGPRs ( (USDA 110) + at 1:1 ratio), and Si-NPs (25 mg L) on soybean plants grown in saline-alkali soil irrigated with wastewater. The results showed that the trio-combination of biochar with PGPRs, (as soil amendments) and Si-NPs (as foliar spraying), was more effective than individual or coupled applications in reducing Cd bioavailability in the soil, minimizing its absorption, translocation and bioconcentration in soybean tissues.

Being a central organ in homeostasis and maintaining the health of the biological system, kidneys are exposed to variable toxicants. Long-term exposure to nephrotoxic molecules causes chronic renal damage that causes fibrosis and loss of function. Such damage can be initiated by oxidative stress which provokes inflammation.

Catheter-associated urinary tract infections (CAUTIs) cause serious complications among hospitalized patients due to biofilm-forming microorganisms which make treatment ineffective by forming antibiotic-resistant strains. As most CAUTI-causing bacterial pathogens have already developed multidrug resistance, there is an urgent need for alternative antibacterial agents to prevent biofilms on catheter surfaces. As a trial to find out such a potential agent of natural origin, the bark of Rottl.

This study introduces a novel synchronous spectrofluorimetry coupled with chemometric tools for the determination of tenofovir and dolutegravir antiretroviral drugs. Utilizing partial least squares regression (PLS) fine-tuned by genetic algorithm as variable selection tool, the developed models demonstrate greater sensitivity, cost-effectiveness, and reduced environmental impact compared to traditional HPLC methods. The model's validation was further confirmed using external validation in addition to QC samples as per ICH M10 guidelines, which yielded high accuracy ranged between 94.

A Schiff base of Chitosan was prepared by condensing of the Chitosan (CS) with six aromatic aldehydes and confirmed by FT-IR, NMR, XRD, TGA, and DSC. XRD results showed the disappeared of peaks at 2θ = 10° for CS and appeared one peaks at around 2θ of 23° for Schiff bases, while TGA was demonstrated that the thermal stability of CS has improved after the modification with the corresponding aldehyde. Also, DSC shows endothermal peak of CS at 100 °C due to the loss of water and second thermal event related to the decomposition of amine units with an exothermic peak at 295 °C, while Schiff bases shows endothermal peak around 70-95 °C which is related to the loss of water for all samples and the second exothermic peak around 260-280 °C is related to the decomposition of the amine group in the polymer units.

In this study, a sensitive and selective spectrofluorimetric method was developed for the determination of the antidiabetic drug nateglinide based on its reaction with the xanthene dye acid red 87 (AR87). A fluorescence quenching process was observed for the AR87 at 545 nm upon the addition of nateglinide, which was exploited for the quantitative analysis. The reaction mechanism was investigated using quantum mechanical calculations suggesting a transfer between the electron-rich AR87 and the electron-deficient nateglinide.
