Department of Environmental Health Sciences, School of Public Health, 1084 University at Albany, Rensselaer, NY, USA.

Lead poisoning is a serious environmental health problem in every country in the world. Exposure to lead results in neurocognitive and behavioral changes, has adverse effects on the immune system, causes anemia, hypertension and perturbs other organ systems. The effects of lead poisoning are most critical for children because their bodies are growing and developing, and particularly because agents that reduce cognitive function and attention span as well as promote disruptive behavior will have life-long consequences.

Mycorrhizae, a form of plant-fungal symbioses, mediate vegetation impacts on ecosystem functioning. Climatic effects on decomposition and soil quality are suggested to drive mycorrhizal distributions, with arbuscular mycorrhizal plants prevailing in low-latitude/high-soil-quality areas and ectomycorrhizal (EcM) plants in high-latitude/low-soil-quality areas. However, these generalizations, based on coarse-resolution data, obscure finer-scale variations and result in high uncertainties in the predicted distributions of mycorrhizal types and their drivers.

The N-methyl-D-aspartate (NMDA)-sensitive glutamate receptor (NMDAR) helps assemble downstream signaling pathways through protein interactions within the postsynaptic density (PSD), which are mediated by its intracellular C-terminal domain (CTD). The most abundant NMDAR subunits in the brain are GluN2A and GluN2B, which are associated with a developmental switch in NMDAR composition. Previously, we used single molecule fluorescence resonance energy transfer (smFRET) to show that the GluN2B CTD contained an intrinsically disordered region with slow, hop-like conformational dynamics.

Article Synopsis
  • Researchers are exploring noninvasive methods for malaria detection, particularly using saliva samples instead of blood, as the current methods are costly and pose health risks.
  • A study conducted in Cameroon involved 100 participants and compared various diagnostic techniques like rapid tests, microscopy, PCR, and LAMP, measuring their accuracy for detecting malaria in both blood and saliva samples.
  • Results indicated that while both blood and saliva tests had relatively low sensitivity, saliva-based tests, especially the LAMP method, showed promise and could be beneficial for malaria diagnosis in resource-limited settings after further validation.

Structural racism toward American Indians and Alaska Natives is found in nearly every policy regarding and action taken toward that population since non-Natives made first contact with the Indigenous peoples of the United States. Generations of American Indians and Alaska Natives have suffered from policies that called for their genocide as well as policies intended to acculturate and dominate them-such as the sentiment from Richard Henry Pratt to "kill the Indian…, save the man." The intergenerational effect is one that has left American Indians and Alaska Natives at the margins of health and the health care system.

SNAP-25 (synaptosomal-associated protein of 25 kDa) is a prototypical intrinsically disordered protein (IDP) that is unstructured by itself but forms coiled-coil helices in the SNARE complex. With high conformational heterogeneity, detailed structural dynamics of unbound SNAP-25 remain elusive. Here, we report an integrative method to probe the structural dynamics of SNAP-25 by combining replica-exchange discrete molecular dynamics (rxDMD) simulations and label-based experiments at ensemble and single-molecule levels.
