State laws on intimate partner violence witnessed by children in the United States.

Intimate partner violence (IPV) is common, and almost half of all IPV takes place in relationships with children in the home. We inventoried laws in the 50 states and the District of Columbia in the United States of America (USA) focused on addressing IPV committed in the presence of children, as these laws could help prevent or remediate this critical health and social issue. Using WestLaw, a web-based legal research service, we identified over 1,200 statutes and 500 regulations.

Willingness to Use Oral and Long-Acting Injectable PrEP in Substance-Using Men who have Sex with Men (SU-MSM) in High HIV Incidence Southern U.S. Cities: A NIDA Clinical Trials Network Study.

In Southern U.S. states with high HIV incidence and low HIV Pre-Exposure Prophylaxis (PrEP) uptake, enhanced efforts to increase interest in and willingness to use PrEP are needed.

Required minimal protein domain of flower for synaptobrevin2 endocytosis in cytotoxic T cells.

Flower, a highly conserved protein, crucial for endocytosis and cellular fitness, has been implicated in cytotoxic T lymphocyte (CTL) killing efficiency through its role in cytotoxic granule (CG) endocytosis at the immune synapse (IS). This study explores the molecular cues that govern Flower-mediated CG endocytosis by analyzing uptake of Synaptobrevin2, a protein specific to CG in mouse CTL. Using immunogold electron microscopy and total internal fluorescence microscopy, we found that Flower translocates in a stimulus-dependent manner from small vesicles to the IS, thereby ensuring specificity in CG membrane protein recycling.

A dystroglycan-laminin-integrin axis coordinates cell shape remodeling in the developing Drosophila retina.

Cell shape remodeling is a principal driver of epithelial tissue morphogenesis. While progress continues to be made in our understanding of the pathways that control the apical (top) geometry of epithelial cells, we know comparatively little about those that control cell basal (bottom) geometry. To examine this, we used the Drosophila ommatidium, which is the basic visual unit of the compound eye.

Interlaboratory and cross-platform accessibility of time-of-flight wood identification database.

The mass spectral database of tree species built by US Fish and Wildlife Service has thousands of entries and has been a valuable resource to combat illegal logging and international trade. The database was and continues to be constructed using a particular ambient ionization time-of-flight mass spectrometry (TOF-MS) platform in the agency branch in Ashland, OR, with which queries of unknown wood samples are investigated exclusively. Laboratories that operate different MS instruments also have an interest in using the database if they can produce valid matches to known samples compatible with the database.
