Toxicity is the most frequently reported reason for modifying or discontinuing the first combined antiretroviral therapy regimens, and it can cause significant morbidity, poor quality of life and also can be an important barrier to adherence, ultimately resulting in treatment failure and viral resistance. Elderly patients with HIV/AIDS (≥ 50 years) may have a different profile in terms of treat...
BACKGROUND Laboratory tests for routine drug of abuse and toxicology (DOA/Tox) screening, often used in emergency medicine, generally utilize antibody-based tests (immunoassays) to detect classes of drugs such as amphetamines, barbiturates, benzodiazepines, opiates, and tricyclic antidepressants, or individual drugs such as cocaine, methadone, and phencyclidine. A key factor in assay sensitivit...
The purpose of this paper is to study the gate field penetration and modulation of molecular channels by presenting field analysis results for different nanoscale geometry structure of SAMFETs. This kind of structure was originally studied by Hendrick Schön and Damle. We have performed numerical simulations in three terminals atomic scale device geometry field effect transistors (FETs), with Lc...
Plasma GH profiles regulate the sexually dimorphic expression of cytochromes P450 and many other genes in rat and mouse liver; however, the proximal transcriptional regulators of these genes are unknown. Presently, we characterize three liver transcription factors that are expressed in adult female rat and mouse liver at levels up to 16-fold [thymus high-mobility group box protein (Tox)], 73-fo...
Burkholderia glumae produces toxoflavin, a phytotoxin with a broad host range, which is a key virulence factor in bacterial rice grain rot. Based on genetic analysis, we previously reported that ToxR, a LysR-type regulator, activates both the toxABCDE (toxoflavin biosynthesis genes) and toxFGHI (toxoflavin transporter genes) operons in the presence of toxoflavin as a coinducer. Quorum sensing r...
Clostridium difficile is one of the most frequent causes of nosocomial gastrointestinal disease. Risk factors include prior antibiotic therapy, bowel surgery, and the immunocompromised state. Direct fecal analysis for C. difficile toxin B by tissue culture cytotoxin B assay (CBA), while only 60 to 85% sensitive overall, is a common laboratory method. We have used 1,003 consecutive, nonduplicate...
