The vacuolar ATPase (v-ATPase) is essential for acidification of intracellular organelles, including synaptic vesicles. Its activity is controlled by cycles of association and dissociation of the ATP hydrolysis (V) and proton transport (V) multi-protein subunits. Mutations in genes coding for both v-ATPase subunits and TBC1D24 cause neurodevelopmental disorders with overlapping syndromes; therefore, it is important to investigate their potentially interrelated functions.

The frog fauna of New Guinea is exceptionally diverse but very poorly known. Here we describe a new species of pelodryadid treefrog that is currently known only from two specimens from a single site in Hela Province in the highlands of Papua New Guinea. Genetic data show that the new species is closely related to the torrent-breeding species Litoria angiana (Boulenger, 1915) from which it can be readily distinguished by its more slender body and limbs, relatively long forelimbs, and aspects of body colouration and tuberculation.

Metabolically obese, normal-weight (MONW) phenotype is characterized by visceral adiposity and obesity-related complications despite the absence of excess body weight. Early identification of this phenotype is crucial to establish preventive strategies. We aim to validate the utility of peripheral blood mononuclear cells (PBMC) transcriptome to detect metabolic risk related to the MONW phenotype at early life stages (young adulthood).

Introduction: In the last decade, hybrid linear accelerator magnetic resonance imaging (Linac-MR) devices have evolved into FDA-cleared clinical tools, facilitating magnetic resonance guided radiotherapy (MRgRT). The addition of a magnetic field to radiation therapy has previously demonstrated dosimetric and electron effects regardless of magnetic field orientation.

Purpose: This study uses Monte Carlo simulations to investigate the importance and efficacy of the magnetic field design in mitigating surface dose enhancement in the Aurora-RT, focusing specifically on contaminant electrons, their origin, and energy spectrum.
