Effects of 3 ionophores and 2 antibiotics on in vitro H(2)S production, IVDMD, total gas production, and VFA profile with or without added S were examined. In Exp. 1, ruminal fluid from 2 ruminally cannulated steers fed a steam-flaked corn-based diet (75% concentrate) without ionophore and antibiotics for 28 d before collection was used to inoculate in vitro cultures. Treatments were control (n...

BACKGROUND Atrial Fibrillation (AF) is a common complication after open heart surgery and is frequently associated with increased hospital stay, complications, and mortality rates. The effect of β-blockers on prevention of supraventricular arrhythmias has been confirmed in several prospective randomized studies. OBJECTIVES This clinical trial aimed to compare the preventive effects of carvedi...

The bioavailability after oral administration of (S)-(-)-2,8-dimethyl-3-methylene-1-oxa-8-azaspiro [4,5] decane-L-tartarate monohydrate (YM796), which is being developed as an antidementia drug, at a dose of 1 mg/kg was very low (3.4%) in rats, but considerably higher (16.1%) in dogs. The oral clearances (CLoral, Dose/AUCoral) in rats and dogs were, respectively, 300 and 18 times more than that...

A new chemical deposition method has been developed to prepare photoconducting n-Sb2S3 thin polycrystalline films. The solution composition of the deposition bath was 0.025M potassium antimonyl tartarate, 0.4M triethanolamine, 0.025M thioacetamide, and 5 • 10-7M silicotungstic acid (STA), respectively. The as-deposited and the annealed films were characterized through x-ray diffraction, neutron...

The nearest neighbor relationships of bovine mitochondrial H(+)-ATPase subunits were investigated by the chemical cross-linking approach using the homobifunctional cleavable reagents dithiobis(succinimidyl propionate) and disuccinimidyl tartrate. Cross-linked proteins were resolved by one- and two-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Individual subunits were de...

The primary structure of the human substance K receptor was established from the sequences of complementary DNA clones isolated from a human jejunal complementary DNA library. It consists of 398 amino acids, including seven putative transmembrane regions. The gene for the human substance K receptor was localized to chromosome region 10p13-10q23, a region with frequent chromosomal abnormalities....

Nicotine affects a variety of cellular process ranging from induction of gene expression to secretion of hormones and modulation of enzymatic activities. The objective of the present study was to study the dose dependent toxicity of nicotine on the oxidative stress in young, adult and old rats which were administered 0.75, 3 and 6 mg kg(-1) nicotine as nicotine hydrogen tartarate intraperitonea...

25 Abstract Aims: To study visceral leishmaniasis (VL) trends in Malta. Methods: Analysis of epidemiological and clinical trends, a veterinary questionnaire and questioning a canine laboratory testing facility. Results: A decline in VL in the past 25 years (1980-2005) was noted for both paediatric (p<0.001) and adult (p=0.002) populations. No seasonal variation in infection rates was found. Ser...

Introduction: Recent reports have shown that intermittent treatment with PTH(1-34) increases callus formation and mechanical strength in experimental fracture healing (1). Thus far, however, the optimal dose for enhancement of fracture healing has not been determined. Furthermore, little is known about the molecular mechanisms by which PTH regulates the fracture healing process. In this study, ...
