(Guanine Nucleotide-Binding Protein, Alpha Stimulating) is a complex gene that encodes the alpha subunit of the stimulatory G protein (Gα), critical for signaling through various G protein-coupled receptors. Inactivating genetic and epigenetic changes in , resulting in Gα deficiency, cause different variants of pseudohypoparathyroidism, which may manifest features of Albright hereditary osteodystrophy (AHO, a syndrome characterized by early-onset obesity and other developmental defects). Recent findings have linked Gα deficiency with isolated, severe, early-onset obesity, suggesting it as a potential, underrecognized cause of monogenic, non-syndromic obesity.

A nanocomposite of iron barium titanate/NiFeO (FBT/NF) was synthesized using sol-gel techniques to form organized hexagonal structures. The effects of NiFeO nanostructures on FBT's phase purity, morphology, and dielectric properties were systematically explored and intensively discussed. TEM imaging confirmed the hexagonal structure, and electrical measurements revealed that para-electric NF influenced the conductivity and impedance of ferroelectric FBT, with a shift in Curie temperature to lower values.

Albumin-coated gold nanoparticles display potential biomedical applications, including cancer research, infection treatment, and wound healing; however, elucidating their interaction with normal cells remains an area with limited exploration. In this study, gold nanorods (GNR) were prepared and coated with bovine serum albumin (BSA) to produce GNR-BSA. The functionalized nanoparticles were characterized based on their optical absorption spectra, morphology, surface charge, and quantity of attached protein.

The kinase suppressor of Ras 2 () gene is associated with monogenic obesity, and loss-of-function variants in have been identified in individuals with severe early-onset obesity. This study investigated variants in 9 pediatric patients with severe early-onset obesity in Qatar using whole genome sequencing among a cohort of 240 individuals. We focused on variants with a minor allele frequency (MAF) below 1% and a Combined Annotation Dependent Depletion (CADD) score above 13 to identify potential causative variants.

Opioid-related deaths are attributed to overdoses, and fentanyl overdose has been on the rise in many parts of the world, including the USA. Glutamate transporter 1 (GLT-1) has been identified as a therapeutic target in several preclinical models of substance use disorders, and β-lactams effectively enhance its expression and function. In the current study, we characterized the metabolomic profile of the nucleus accumbens (NAc) in fentanyl-overdose mouse models, and we evaluated the protective effects of the functional enhancement of GLT-1 using β-lactams, ceftriaxone, and MC-100093.

Repeated exposure to tobacco smoke causes neuroinflammation and neuroplasticity, which correlates with smoking withdrawal-induced anxiety. The purpose of this study was to investigate the anticipated involvement of antioxidant-rich nanoparticles (NPs) prepared by oxidation-triggered polymerization of green tea catechins in impacting these effects in a rat model of tobacco smoke exposure. Exposure to tobacco smoke was carried out for 2 h a day, 5 days a week, for a total of 36 days.

Vaccine literacy is a significant part of health literacy. Although several tools have been developed to assess vaccine literacy, such tools are lacking in Arabic. Validating an Arabic version of a tool that evaluates vaccine literacy is critically important, as it would aid in understanding the decision-making process regarding vaccinations among individuals in Arabic-speaking countries.
