At optimal growth pH (3.0) Thiobacillus acidophilus maintained an internal pH of 5.6 (delta pH of 2.6 units) and a membrane potential (delta psi) of some +73 mV, corresponding to a proton motive force (delta p) of -83 mV. The internal pH remained poised at this value through external pH values of 1 to 5, so that the delta pH increased with decreasing external pH. The positive delta psi increase...

In the present study we used regression analyses to evaluate the effects of stearic acid (18:0) on total cholesterol (TC), low-density-lipoprotein-cholesterol (LDL-C), and high-density-lipoprotein-cholesterol (HDL-C) concentrations (mmol/L). Using data from 18 articles, we developed the following predictive equations (monounsaturated fatty acids, MUFAs; polyunsaturated fatty acids, PUFAs): delt...

The Saccharomyces cerevisiae PHO85 gene encodes a nonessential cyclin-dependent kinase that associates with 10 cyclin subunits. To survey the functions provided by Pho85, we identified mutants that require PHO85 for viability. We identified mutations that define seven Pho Eighty-Five Requiring or Efr loci, six of which are previously identified genes-BEM2 (YER155C), SPT7 (YBR081C), GCR1 (YPL075...

‎Let $G$ be a finite group which is not a cyclic $p$-group‎, ‎$p$ a prime number‎. ‎We define an undirected simple graph $Delta(G)$ whose‎ ‎vertices are the proper subgroups of $G$, which are not contained in the‎ ‎Frattini subgroup of $G$ and two vertices $H$ and $K$ are joined by an edge‎ ‎if and only if $G=langle H‎ , ‎Krangle$‎. ‎In this paper we classify finite groups with planar graph‎. ‎...

In this paper‎, ‎using the discrete Fourier transform in the finite-dimensional Hilbert space C^n‎, ‎a class of nonRieszable equal norm tight frames is introduced ‎and‎ using this class, a bound for Fiechtinger Conjecture is presented. By the Fiechtinger Conjecture that has been proved recently, for given A,C>0 there exists a universal constant delta>0 independent of $n$ such that every C-equal...

Polymyositis mediated by gamma/delta T cells is a unique disease in which autoaggressive T lymphocytes surround, invade, and destroy muscle fibers. Histochemically, the vast majority of muscle-infiltrating T cells in a patient with polymyositis were reactive with a pan-gamma/delta T cell receptor (TCR)-specific monoclonal antibody (TCR-delta 1+), but unlike > 90% of peripheral blood gamma/delta...

The germline repertoire of variable genes for the TCR-gamma/delta is limited. This, together with the availability of several V delta-specific and a C delta-specific mAbs, has made it possible to assess differences in the TCR-gamma/delta repertoire in man. TCR-gamma/delta cells expressing particular V gene segments have been previously shown to be localized in different anatomical sites. In thi...

Recently, Shifted Delta Cepstral (SDC) feature was reported to produce superior performance to the delta and delta-delta features in cepstral feature based language identification (LID) systems [1, 2]. This paper examines the application of SDC features in speaker verification and evaluates its robustness to channel mismatch, manner of speaking and session variability. The result of the experim...

The stable isotopes of hydrogen, carbon, nitrogen, and oxygen provide insights into a heterotrophic organism's diet and geographic origin. Although the contribution of food delta (2)H and delta (18)O to the final tissue signal will not vary for constrained diets, it will for animals eating varied diets, that is, humans. This study surveyed the isotopic range in one portion of the American diet,...

Background: Hb A2 is elevated in subjects with beta thalassemia minor but small percent of carriers have normal Hb A2 with elevated levels of HbF (2-10%). This type of thalassemia is called delta beta thalassemia, and can be missed in pre-marriage hematologic consults or screening which leads to increased risk of child birth with beta thalassemia major. Materials and Methods: In this prospe...
