Glucocorticoids and androgens affect each other in several ways. In metabolic organs such as adipose tissue and the liver, androgens enhance glucocorticoid-induced insulin resistance and promote fat accumulation in male mice. However, the direct contribution of the androgen receptor (AR) to these effects is unknown.

Hyperparathyroidism-jaw tumor syndrome is a rare form of syndromic primary hyperparathyroidism. We describe a young female with a history of common precursor B acute lymphoblastic leukaemia who was diagnosed with overt primary hyperparathyroidism due to a pathogenic CDC73 variant (c.25C > T).

Irreversible electroporation (IRE) is a minimally invasive ablation technique that compromises integrity of the cell membrane through the application of short duration, high voltage electric pulses to induce cell death. Adverse effects of IRE such as muscle contractions are reduced with higher frequency biphasic pulsing, commonly known as high-frequency irreversible electroporation (H-FIRE). IRE and H-FIRE treatments have shown to increase immune activation through the induction of both immediate and delayed cell death, indicated by the release of damage-associated molecular pathways, antigens, and proteins.

Article Synopsis
  • Angelman syndrome (AS) is a rare genetic disorder impacting neurodevelopment, with an estimated prevalence of 1 in 20,000, but lacks comprehensive data on life expectancy and death rates due to a lack of diagnostic codes until 2018.
  • A social media initiative by AS caregivers gathered data on 220 deaths, revealing respiratory illness as the leading cause, followed by accidents and seizures, with sudden unexpected death in sleep (SUDS) also being a notable concern.
  • The study found that 91% of individuals with AS have epilepsy, suggesting that some SUDS cases could relate to sudden unexpected deaths in epilepsy (SUDEP), and highlights the need for more research despite limitations

fungi are key producers of pharmaceuticals, enzymes, and food products and exhibit diverse lifestyles, ranging from saprophytes to opportunistic pathogens. To improve understanding of species diversity, identify key environmental factors influencing their geographic distributions, and estimate the impact of future climate change, we trained a random forest machine learning classifier on 30,542 terrestrial occurrence records for 176 species (~40% of known species in the genus) and 96 environmental variables. We found that regions with high species diversity are concentrated in temperate forests, which suggests that areas with mild seasonal variation may serve as diversity hotspots.
