Virtual teaching kitchen classes and cardiovascular disease prevention counselling among medical trainees.

Background: Hands-on culinary medicine education for medical trainees has emerged as a promising tool for cardiovascular health promotion.

Purpose: To determine whether virtual culinary medicine programming associates with Mediterranean diet (MedDiet) adherence and lifestyle medicine competencies among medical trainees across the USA.

Method: A total of 1433 medical trainees across 19 sites over a 12-month period were included.

Separation of postprandial lipoproteins: improved purification of chylomicrons using an ApoB100 immunoaffinity method.

Elevated levels of triglyceride-rich lipoproteins (TRLs), both fasting and postprandial, are associated with increased risk for atherosclerosis. However, guidelines for treatment are defined solely by fasting lipid levels, even though postprandial lipids may be more informative. In the postprandial state, circulating lipids consist of dietary fat transported from the intestine in chylomicrons (CMs; containing ApoB48) and fat transported from the liver in VLDL (containing ApoB100).

A systematic library for comprehensive overexpression screens in Saccharomyces cerevisiae.

Modern genetic analysis requires the development of new resources to systematically explore gene function in vivo. Overexpression screens are a powerful method to investigate genetic pathways, but the goal of routine and comprehensive overexpression screens has been hampered by the lack of systematic libraries. Here we describe the construction of a systematic collection of the Saccharomyces cerevisiae genome in a high-copy vector and its validation in two overexpression screens.

Genetic analysis connects SLX5 and SLX8 to the SUMO pathway in Saccharomyces cerevisiae.

MOT1 encodes an essential ATPase that functions as a general transcriptional regulator in vivo by modulating TATA-binding protein (TBP) DNA-binding activity. Although MOT1 was originally identified both biochemically and in several genetic screens as a transcriptional repressor, a combination of subsequent genetic, chromatin immunoprecipitation, and microarray analysis suggested that MOT1 might also have an additional role in vivo as a transcriptional activator. To better understand the role(s) of MOT1 in vivo, we selected for genomic suppressors of a mot1 temperature-sensitive mutation.
