CONTEXT The main threats to adolescents' health are the risk behaviors they choose. How their social context shapes their behaviors is poorly understood. OBJECTIVE To identify risk and protective factors at the family, school, and individual levels as they relate to 4 domains of adolescent health and morbidity: emotional health, violence, substance use,(More)
In addition to coordinating immune and inflammatory responses, NF-kappaB/Rel transcription factors control cell survival. Normally, NF-kappaB dimers are sequestered in the cytoplasm by binding to inhibitory IkappaB proteins, and can be activated rapidly by signals that induce the sequential phosphorylation and proteolysis of IkappaBs. Activation of(More)
Although the presence of chitin in nematodes is well documented little is known about its synthesis in this phyletic group. The recently completed genome sequence of Caenorhabditis elegans predicts two sequences with homology to chitin synthases (chitin-UDP acetyl-glucosaminyl transferase; EC We show that these genes are differentially expressed(More)
The C-S lyase aecD (MetC) from skin corynebacteria plays an important role in body odour formation by releasing odoriferous sulfanylalkanols from cysteine conjugates in human axilla secretions. The expression of the aecD gene from Corynebacterium jeikeium K411, a strain originally isolated from the human axilla, was down-regulated in cells grown in minimal(More)
