IL-7 promotes integrated glucose and amino acid sensing during homeostatic CD4 T cell proliferation.

Interleukin (IL)-7 promotes T cell expansion during lymphopenia. We studied the metabolic basis in CD4 T cells, observing increased glucose usage for nucleotide synthesis and oxidation in the tricarboxylic acid (TCA) cycle. Unlike other TCA metabolites, glucose-derived citrate does not accumulate upon IL-7 exposure, indicating diversion into other processes.

Structural basis of nearest-neighbor cooperativity in the ring-shaped gene regulatory protein TRAP from protein engineering and cryo-EM.

The homo-dodecameric ring-shaped RNA binding attenuation protein (TRAP) from binds up to twelve tryptophan ligands (Trp) and becomes activated to bind a specific sequence in the 5' leader region of the operon mRNA, thereby downregulating biosynthesis of Trp. Thermodynamic measurements of Trp binding have revealed a range of cooperative behavior for different TRAP variants, even if the averaged apparent affinities for Trp have been found to be similar. Proximity between the ligand binding sites, and the ligand-coupled disorder-to-order transition has implicated nearest-neighbor interactions in cooperativity.

Impact of On-Road U.S. Vehicle Electrification and Lightweighting on Critical Materials Demand.

The electrification of the transport sector is crucial for reducing greenhouse gas emissions and the reliance on fossil fuels. Battery electric vehicles (BEVs) depend on critical materials (CMs) for their batteries and electronic components, yet their widespread adoption may face constraints due to the limited availability of CMs. This study assesses the implications of vehicle electrification and lightweighting (material substitution) on the U.

Variations and Opportunities in Postnatal Management of Hemolytic Disease of the Fetus and Newborn.

Importance: Preventive efforts in pregnancy-related alloimmunization have considerably decreased the prevalence of hemolytic disease of the fetus and newborn (HDFN). International studies are therefore essential to obtain a deeper understanding of the postnatal management and outcomes of HDFN. Taken together with numerous treatment options, large practice variations among centers may exist.

Applying principles of adult learning to rural health electives in a medical school curriculum.

The health disparities between rural and urban populations in Australia, driven by socioeconomic, environmental, and healthcare access factors, highlight the urgent need for rural-focused medical education. The Melbourne Medical School's Rural Health Discovery program addresses this need by integrating adult learning principles within a redesigned curriculum that includes the Rural Health Foundations and Integrating Rural Health topics. These Discovery topics engage medical students from diverse backgrounds through a blend of self-directed learning, problem-solving, and immersive clinical placements in rural settings.

Challenges and perspectives with understanding the concept of mental fatigue.

Mental fatigue is referred to as a psychophysiological or neurobiological state caused by prolonged periods of demanding cognitive activity. Sports and exercise science research have investigated the effects of experimentally induced mental fatigue on cognitive performance, with mixed results. It has been suggested that negative effects of mental fatigue on cognition performance in laboratory studies could translate to impaired sport performance.
