Prenatal Perfluoroalkyl Substance Exposure in Association with Global Histone Post-Translational Methylation in 2-Year-Old Children.

Perfluoroalkyl substances (PFASs) have elimination half-lives in years in humans and are persistent in the environment. PFASs can cross the placenta and impact fetal development. Exposure to PFASs may lead to adverse effects through epigenetic mechanisms.

Modulating Solid-Solution Solubility to Enhance Thermoelectric Performance and Maintain Structural Stability in Phase-Transition Silver Chalcogenides.

Silver chalcogenides exhibit exceptional transport properties but face structural instability at high temperatures, limiting their practical applications. Using AgTe as a model, it is confirm that silver whisker growth above the phase transition renders AgTe unsuitable for thermoelectric applications. Here, the whisker growth mechanism is investigated and propose an inhibition strategy, overcoming a major obstacle in using silver chalcogenides.

Pro-inflammatory macrophage activation does not require inhibition of oxidative phosphorylation.

Pro-inflammatory macrophage activation is a hallmark example of how mitochondria serve as signaling organelles. Oxidative phosphorylation sharply decreases upon classical macrophage activation, as mitochondria are thought to shift from ATP production towards accumulating signals that amplify effector function. However, evidence is conflicting regarding whether this collapse in respiration is essential or dispensable.

Successful Microablative Fractional Carbon Dioxide Laser Therapy for Vulvar Lichen Sclerosus: A Case Report and Mini-review.

Vulvar lichen sclerosus (VLS) is a chronic inflammatory skin disorder affecting the vulvar region. VLS predominantly affects women, and most cases occur after menopause. Common symptoms include itching, skin-whitening, pain, discomfort, fissures, and scarring.
