After recent civil rights expansions for sexual minorities in the United States, we updated previous findings on population-level attitudes toward homosexuality measured in the General Social Survey. In 2014, 40.1% of respondents reported that homosexuality was "always wrong" compared with 54.8% in 2008 (P < 0.001). Although black and Hispanic respondents consistently reported more negative attitudes regarding homosexuality than white respondents throughout 2008 to 2014, the percentage declined among all racial/ethnic groups. Among MSM, more positive attitudes were associated with HIV testing. Research shows a potential association between homophobia and HIV risk; thus, these population-level changes may promote better health among MSM.

Patients in need of a kidney transplant have the option of receiving a kidney from a living donor or a deceased donor. Patients in the United States who do not have an available living donor typically wait on the deceased donor waiting list for an average of three to five years, although some patients may wait longer. The waiting list is very complex and intended to allocate kidneys in a fair and equitable manner.

Purpose: Homoarginine (hArg) is an arginine metabolite that has been known for years, but its physiological role in the body remains poorly understood. For instance, it is well known that high hArg concentrations in the blood are protective against several disease states, yet the mechanisms behind these health benefits are unclear. This review compiles what is known about hArg, namely its synthetic pathways, its role in different diseases and conditions, and its proposed mechanisms of action in humans and experimental animals.

In this Perspective, we highlight the emergence of target-oriented syntheses of complex molecules composed of Si-Si (oligosilanes) rather than C-C bonds. Saturated oligosilanes structurally resemble alkanes with respect to a tetrahedral geometry, a preference for a staggered conformation in linear chains, the ability to form stable small rings, and tetrahedral stereochemistry at asymmetrically functionalized Si centers. There are also critical differences, for example, differences in multiple bonding and the ability to form penta- and hexacoordinated structures, that mean that chemical reactivity and, in particular, rules for stereoselective synthesis do not cleanly translate from carbon to silicon.

Most traditional optical biosensors operate through molecular recognition, where ligand binding causes conformational changes that lead to optical perturbations in the emitting motif. Optical sensors developed from single-stranded DNA-functionalized single-walled carbon nanotubes (ssDNA-SWCNTs) have started to make useful contributions to biological research. However, the mechanisms underlying their function have remained poorly understood.

Methods: Data are based on reports of fetal death filed in the 50 states and the District of Columbia and collected via the National Vital Statistics System.
