Article Synopsis
  • Archaeal group II chaperonins, or heat shock proteins (HSPs), are crucial for protein folding and protection during thermal stress in Sulfolobales, especially when faced with thermal shock.
  • HSPs maintain structural integrity at neutral pH and varying temperatures but show significant changes at ultra-low pH (pH 2), with HSPα and HSPβ being more thermostable than HSPβ-coh.
  • Molecular dynamics simulations support lab findings, revealing stability differences among HSP subtypes and highlighting limitations in acid tolerance despite their thermal resilience.

Hippocampal dentate gyral dysplasia is well-described in temporal lobe epilepsy and may be a risk factor for sudden, unexpected death in several populations: infants (sudden infant death syndrome [SIDS], sudden unexpected infant death [SUID]), toddlers (sudden unexpected death of a child [SUDC]), and epileptics (sudden unexpected death in epilepsy [SUDEP]). We examined reports and histopathological slides from autopsies performed at our institution from 2008 through 2016 to determine whether the presence or absence of any of the described forms of such dysplasias (duplications, hyperconvolutions, and granule cell dispersion, including bilamination), correlated with the causes of death. From well over 4000 autopsies, we identified 949 autopsies with a neuropathology examination by a neuropathologist.

Background: Organisms frequently experience environmental stresses that occur in predictable patterns and combinations. For wild Saccharomyces cerevisiae yeast growing in natural environments, cells may experience high osmotic stress when they first enter broken fruit, followed by high ethanol levels during fermentation, and then finally high levels of oxidative stress resulting from respiration of ethanol. Yeast have adapted to these patterns by evolving sophisticated "cross protection" mechanisms, where mild 'primary' doses of one stress can enhance tolerance to severe doses of a different 'secondary' stress.

We conducted a randomized controlled trial to determine whether an after-school program paired with a cash transfer (a conditional cash transfer) or a cash transfer alone (an unconditional cash transfer) can help improve health and economic outcomes for young men between the ages of 14 and 17 whose parents have low incomes and who live in neighborhoods with high crime rates. We find that receiving the cash transfer alone was associated with an increase in healthy behaviors (one of our primary outcome composite measures) and that the cash transfer paired with after-school programming was associated with an improvement in the financial health of participants (one of our secondary outcome composite measures). We find no differences in spending on alcohol, marijuana, cigarettes, or other drugs between either the treatment group and the control group.

Article Synopsis
  • Childhood diseases represent significant public health challenges linked to environmental exposures, collectively known as the exposome, impacting various health outcomes in children.
  • A comprehensive analysis reviewed studies on 88 environmental factors, finding that 44 factor-outcome pairs had a "very likely" level of evidence for negative health impacts, while many others showed either limited or no evidence.
  • The most concerning environmental factors included chemicals like HCB, PCBs, and PFOA, which were associated with multiple adverse health outcomes, emphasizing the need for ongoing research and policy action to address these risks.
