DinG is an Escherichia coli DNA damage-inducible gene (1, 2). Sequence database searches (3, 4) revealed marginally significant similarities between the 637 amino acid DinG protein, yeast DNA helicases Chll, Rad3 and Rad 15, and the human helicase ERCC2. Remarkably, the similarities included some of the motifs conserved in the 'DExD/H' helicase superfamily (5). However, DinG sequence did not co...

A molecular assay for diagnosis of light brown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), in North America is reported. The assay multiplexes two TaqMan real-time polymerase chain reaction (RT-PCR) probe systems that are designed to target DNA segments of the internal transcribed spacer region 2 (ITS2) and 18S rRNA gene. The RT-PCR probe designed for the 18S target re...

Mitochondria in cells comprise a tubulovesicular reticulum shaped by dynamic fission and fusion events. The multimeric dynamin-like GTPase Drp1 is a critical protein mediating mitochondrial division. It harbors multiple motifs including GTP-binding, middle, and GTPase effector (GED) domains that are important for both intramolecular and intermolecular interactions. As for other members of the d...

Background.  Due to the unintended potential misclassifications of the World Health Organization (WHO) immunological failure criteria in predicting virological failure, limited availability of treatment options, poor laboratory infrastructure, and healthcare providers' confidence in making switches, physicians delay switching patients to second-line antiretroviral therapy (ART). Evaluating whet...
