MOTIVATION The BacTregulators database is intended to collect and to integrate information on proteins belonging to defined families of transcriptional regulators in prokaryotes. RESULTS The BacTregulators database currently contains data on two families of transcriptional regulators: AraC-XylS and TetR. The proteins included in the BacTregulators database have been identified by screening 12...

Orthostatic hypotension is associated with cardiovascular disease and mortality, but little is known of its association with incident chronic kidney disease. We evaluated this association in the Atherosclerosis Risk in Communities study. Orthostatic hypotension was defined as a decrease in systolic blood pressure ≥ 20 mm Hg or a decrease in diastolic blood pressure ≥ 10 mm Hg within 2 minutes o...

The nucleotide sequence of a segment of the mtDNA molecule of Drosophila yakuba which contains the A+T-rich region and the small and large rRNA genes separated by the tRNAval gene has been determined. The 5' end of the small rRNA gene was located by S1 protection analysis. In contrast to mammalian mtDNA, a tRNA gene was not found at the 5' end of the D. yakuba small rRNA gene. The small and lar...

This study was carried out to develop a hyperspectral imaging system in the near infrared (NIR) region (900-1700 nm) to evaluate the quality of cooked turkey hams. Different qualities of turkey hams were studied based on their chemical ingredients and processing parameters used during processing. Hyperspectral images were acquired for ham slices originated from each quality class and then their...

OBJECTIVE Relative to whites, African Americans have lower circulating triglycerides (TG) and greater highdensity lipoprotein cholesterol. The metabolic basis for this difference is not known. This study was conducted to test the hypothesis that insulin-induced suppression of free fatty acids (FFA) results in lower serum TG in African American versus white prepubertal children. RESEARCH METHO...

Streptomyces coelicolor produces four genetically and structurally distinct antibiotics in a growth-phase-dependent manner. S. coelicolor mutants globally deficient in antibiotic production (Abs(-) phenotype) have previously been isolated, and some of these were found to define the absB locus. In this study, we isolated absB-complementing DNA and show that it encodes the S. coelicolor homolog o...

Diagnosing arrhythmogenic right ventricular cardiomyopathy (ARVC) is often challenging because no single diagnostic tool is available to detect the disease. We evaluated whether analysis of plakoglobin, N-cadherin, and connexin-43 immunoreactivity can be used as a significant test in diagnosis of ARVC. We selected subjects with suspicion of ARVC (n=22) in patients who underwent endomyocardial b...

The Medical Poem ("Al-Urjuzah Fi Al-Tibb") of Ibn Sina (Avicenna, 980-1037), is the subject of this primary-source study evaluating its scientific value, poetics and pedagogical significance as well as assessing its role in the transmission of medical knowledge to Medieval Europe. In addition to one original manuscript and two modern editions, the English translation by Krueger was also studied...
