The study describes reproductive health in two districts of the Luangprabang Province in northern Lao PDR. The aim was to find out whether training traditional birth attendants (TBA) might have an impact on reproductive health. In June/July 2000, a total of 298 women of reproductive age, with children below two years of age, from 30 villages were interviewed by means of a closed questionnaire. ...

Trenbolone acetate (TBA) is a high-value steroidal growth promoter often administered to beef cattle, whose metabolites are potent endocrine-disrupting compounds. We performed laboratory and field phototransformation experiments to assess the fate of TBA metabolites and their photoproducts. Unexpectedly, we observed that the rapid photohydration of TBA metabolites is reversible under conditions...

BACKGROUND Remediation of tert-butyl alcohol (TBA) in subsurface waters should be taken into consideration at reformulated gasoline contaminated sites since it is a biodegradation intermediate of methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), and tert-butyl formate (TBF). The effect of temperature on TBA biodegradation has not been not been published in the literature. METHODS...

Real-time heuristic search algorithms are used for planning by agents in situations where a constantbounded amount of deliberation time is required for each action regardless of the problem size. Such algorithms interleave their planning and execution to ensure real-time response. Furthermore, to guarantee completeness, they typically store improved heuristic estimates for previously expanded s...

1. The anabolic agent trenbolone acetate (3-oxo-17beta-hydroxy-4,9,11-oestratriene acetate; TBA) given subcutaneously to female rats increased their growth rate compared with that of the placebo-treated controls. 2. The increased growth rate of the TBA-treated rats was not a consequence of an increased water retention. The TBA-treated rats had a significantly higher (P less than 0.01) total car...

Structure and bonding patterns in tert-butanol (TBA)−water mixtures are investigated by using molecular dynamics simulations with the effective fragment potential (EFP) method. EFP is a model potential in which all parameters are obtained from a set of ab initio calculations on isolated fragment molecules. Mixed-basis EFP potentials (called “EFPm”) for water and TBA molecules were prepared and ...

At each of three locations, 400 steers and an equal number of heifers were randomized to 10 treatment groups. The purpose of the studies was to evaluate the response of feedlot steers and heifers to single implants containing a combination of estradiol benzoate (EB) and trenbolone acetate (TBA) at two different ratios each at three doses. The selected ratios corresponded to 1E2(estradiol-17 bet...

A thrombin binding aptamer (TBA) is a synthetic 15-nt DNA oligomer that binds human alpha thrombin with high specificity and reversibly suspends the coagulation cascade and platelet formation. It has been established that TBA folds intramolecularly into a G-quadruplex (GQ) structure in solution, forming two G tetrads and three loops1. Two TT loops play a critical role in recognizing the target ...

BACKGROUND In Fontan and atrial switch patients, transcatheter ablation is limited by difficult access to the pulmonary venous atrium. In recent years, transbaffle access (TBA) has been described, but limited data document its safety and utility. METHODS AND RESULTS All ablative electrophysiological study cases of this population performed between January 2006 and December 2010 at Boston Chil...

We previously showed that a combined trenbolone acetate (TBA)/estradiol-17beta (E2) implant significantly increases IGF-I mRNA levels in the LM of feedlot steers by 28 d after implantation. Here we compare the effects of E2 (25.7 mg), TBA (120 mg), and combined TBA (120 mg)/E2 (24 mg) implants on IGF-I, IGF-I receptor (IGFR-1), estrogen receptor (ER)-alpha and androgen receptor (AR) mRNA levels...
