cADP-ribose, which is produced by ecto-ADP-ribosyl cyclase of CD38 or bone marrow stromal cell antigen-1 (BST-1), is a key regulator of Ca2+-induced calcium release in an Ins(1,4,5)P3-independent manner. In the present study, we have identified a specific peptide inhibitor for ADP-ribosyl cyclase of BST-1. A 15-mer random peptide phage library was screened with a soluble form of BST-1 expressed...

Recently, there has been significant interest toward the development of tunable dielectric materials for voltage-controlled, frequency-agile phase shifters and filters operating in the microwave regime. The fundamental challenge in designing materials systems for such tunable devices is the simultaneous requirement of high dielectric tunability ([40%) over a large temperature interval (-10 C to...

Major objectives were to evaluate effects of three schemes of bST-supplementation of Holstein cows (142.8 mg/14 d, POSILAC) during the prepartum and/or postpartum periods through 63 d (±3 d) of lactation. Measures evaluated the potential of treatments to improve body weight (BW) and body condition score (BCS), provoke changes in plasma concentrations of somatotropin (ST) and IGF-I, and improve ...

An experiment was conducted to examine effects of bovine ST (bST) on serum hormone concentrations, pregnancy rates, and offspring performance. Before initiation of a fall breeding period, 75 Rambouillet ewes (68.8 ± 1.5 kg) received an intravaginal insert containing 0.3 g of progesterone (P4) to synchronize onset of estrus. After 12 d, inserts were removed (d 0), and ewes (stratifi ed by BW and...

The objective was to determine the effects of bovine somatotropin (bST) and two artificial insemination (AI) protocols on reproductive performance of Holstein cows. Lactating cows (n = 840) were assigned at 37 d in milk (DIM) to one of four treatments in a 2 x 2 factorial arrangement. Treatments consisted of either bST (500 mg/14 d) starting at 63 +/- 3 DIM or no bST (control), with cows either...

The early SV40 BstXI-BamHI (Bst/Bam) DNA fragment encodes exclusively for the second exon of the large T-antigen and contains the intact small t-antigen intron. Rat cells transformed by the p14T, a construct that carries the Bst/Bam DNA fragment as a tail-to-head tandem duplication, synthesize a truncated T-antigen (T1-antigen) without having a direct equivalent at the DNA level. Formation of t...

OBJECTIVE The efficacy and safety of BST-CarGel®, a chitosan scaffold for cartilage repair was compared with microfracture alone at 1 year during a multicenter randomized controlled trial in the knee. This report was undertaken to investigate 5-year structural and clinical outcomes. DESIGN The international randomized controlled trial enrolled 80 patients, aged 18 to 55 years, with grade III ...

OBJECTIVE To assess the effect of British Summer Time (BST) on road traffic accident casualties and to analyse whether the introduction of year round BST would result in reductions in casualty numbers. DESIGN A comparative study of road traffic accident data from before and after the onset of BST. SETTING The county of Cheshire. SUBJECT Data from a total of 4185 casualties from the period...

Films of the composition Ba 0.8 Sr 0.2 TiO 3 (BST) were synthesized by method high-frequency (HF) sputtering on buffer layer a ferroelectric film PbZr x Ti 1-x O (PZT). Comparative results electrophysical properties three different metal--dielectric--metal (MDM)-structures are presented: Pt/BST/Ni, Pt/PZT/Ni, and Pt/PZT-BST/Ni. Keywords: structures, films , layer, properties.
