OBJECTIVE Sperm must be properly prepared in in vitro fertilization (IVF)-embryo transfer (ET) programs in order to control the fertilization rate and ensure that embryos are of high quality and have appropriate developmental abilities. The objective of this study was to determine the most optimal sperm preparation method for IVF. METHODS Patients less than 40 years of age who participated in...

The unc-17 gene encodes the vesicular acetylcholine transporter (VAChT) in Caenorhabditis elegans. unc-17 reduction-of-function mutants are small, slow growing, and uncoordinated. Several independent unc-17 alleles are associated with a glycine-to-arginine substitution (G347R), which introduces a positive charge in the ninth transmembrane domain (TMD) of UNC-17. To identify proteins that intera...

BACKGROUND Overutilization of stress ulcer prophylaxis (SUP) in the intensive care unit (ICU) is common. Acid-suppressive therapies routinely used for SUP are best reserved for patients with greatest risk of clinically important bleeding as they have been associated with nosocomial pneumonia, Clostridium difficile infection and increased hospital cost. OBJECTIVE The primary objective was to r...

BACKGROUND Little is known about why physicians prescribe inappropriate stress ulcer prophylaxis (SUP) among nonintensive care unit (ICU) hospitalized patients without supporting evidence. This study seeks to understand which factors influence physician prescribing behavior regarding SUP. DESIGN We designed a cross sectional web-based survey to assess physicians' knowledge, beliefs, and behav...

Immunosuppressive oligodeoxynucleotides (Sup ODNs) containing repetitive TTAGGG motifs reduce inflammation and, thus, may have an impact on inflammation‑related tumor growth. In this study, we found a significant antiproliferative effect of Sup ODNs on the A549 non‑small cell lung cancer (NSCLC) cell line compared to those treated with control ODN...

Experiments were conducted to determine the pathway of melamine metabolism by Klebsiella terragena (strain DRS-1) and the effect of added NH(inf4)(sup+) on the rates and extent of melamine metabolism. In the absence of added NH(inf4)(sup+), 1 mM melamine was metabolized concomitantly with growth. Ammeline, ammelide, cyanuric acid, and NH(inf4)(sup+) accumulated transiently in the culture medium...

The effect of pH on the growth and physiology of Bacillus thermoamylovorans, a new moderately thermophilic and non-spore-forming bacterium isolated from palm wine, was studied. Growth occurred from pH 5.4 to 8.5, with optimum growth at 7.0. During the exponential growth phase at optimum pH, glucose was consumed at the maximum rate (qs), 17.87 mmol g(sup-1) h(sup-1), and was mainly fermented int...

The SUPERMAN (SUP) gene of Arabidopsis is involved in controlling cell proliferation in stamen and carpel primordia and in ovules during flower development. The SUP gene encodes a transcription factor with a C2H2-type zinc finger motif, a serine/proline-rich domain, a basic domain, and a leucine-zipper-like domain and is expressed in a very limited region in stamen primordia and in the developi...

where u can be interpreted as the velocity field of an incompressible fluid motion, and p is then the associated pressure, the constant μ is the viscosity coefficient of the fluid. For simplicity, we consider homogenous Dirichlet boundary condition for the velocity, i.e. u|∂Ω = 0 and μ = 1. The conditions for the well posedness is known as inf-sup condition or Ladyzhenskaya-Babuška-Breezi (LBB)...
