Relationship of Plasma Apolipoprotein C-I Truncation With Risk of Diabetes in the Multi-Ethnic Study of Atherosclerosis and the Actos Now for the Prevention of Diabetes Study.

Objective: Higher truncated-to-native apolipoprotein (apo) C-I proteoform ratios (C-I'/C-I) are associated with favorable cardiometabolic risk profiles, but their relationship with longitudinal changes in insulin resistance (IR) and incident diabetes is unknown.

Research Design And Methods: Plasma apoC-I proteoforms were measured by mass spectrometry immunoassay at baseline in 4,742 nondiabetic participants in the Multi-Ethnic Study of Atherosclerosis (MESA) and 524 participants with prediabetes in the Actos Now for Prevention of Diabetes (ACT NOW) study. The primary outcome was incident diabetes (fasting glucose [FG] ≥7.

Serologic Cross-reactivity of Murine Parvovirus Capsid Antigens.

Genomic sequence analysis of autonomous parvoviruses within the genus generates 2 groups that are principally of mouse origin: the minute virus of mice (MVM) strains (MVMp, MVMi, MVMc, MVMm) and the mouse parvovirus (MPV)-like strains (MPV-1, MPV-2, MPV-3, MPV-4, MPV-5, HaPV, LuIII). Baculovirus-expressed recombinant capsid protein (rVP2) from each of these 11 parvovirus strains were produced, purified, and demonstrated to form virus-like particles. Each rVP2 preparation was then used as antigen in a multiplex fluorescent immunoassay and to immunize 5 different strains of mice.

What a mix! Volatile organic compounds and worker exposure in small business beauty salons in Tucson, Arizona.

Introduction: Small business beauty salons have volatile organic compounds (VOCs) in their workplace air. VOCs are present as ingredients in beauty or hair products. They may also form because of chemical reactions, where thermal-styling elements accelerate the volatilization of these compounds.
