assume that $a$‎, ‎$b$ are banach algebras and that $m:atimes brightarrow b$‎, ‎$m^prime:atimes arightarrow b$ are bounded bilinear mappings‎. ‎we study the relationships between arens regularity of $m$‎, ‎$m^prime$ and the banach algebras $a$‎, ‎$b$‎. ‎for a banach $a‎$‎-bimodule $b$‎, ‎we show that $b$ factors with respect to $a$ if and only if $b^{**}$ is unital as an $a^{**}‎$‎-module‎. ‎le...

the german cockroach is an important household insect pest mechanically involved in transmission of a variety of diseases to humans. different classes of insecticides have extensively been used for its control leading to insecticide resistance development. hence, for an optimal control of this pest, the status and underlying mechanisms of insecticide resistance should be studied in this group o...

The gene encoding 2-oxo-hept-3-ene-1,7-dioic acid (OHED) hydratase (HpcG) was cloned into the high-expression plasmid pET26b and overexpressed in Escherichia coli BL21(DE3). The enzyme was purified in three steps to greater than 95% purity prior to crystallization. Crystals were obtained by the hanging-drop vapour-diffusion method at 277 K in a number of screening conditions. Crystals measuring...

Glucuronidation of thyroxine is a major metabolic pathway facilitating its excretion. In this study, we characterized the glucuronidation of thyroxine in human liver, jejunum, and kidney microsomes, and identified human UDP-glucuronosyltransferase (UGT) isoforms involved in the activity. Human jejunum microsomes showed a lower K(m) value (24.2 microM) than human liver (85.9 microM) and kidney (...

We give a short and elementary proof of an inverse Bernsteintype inequality found by S. Khrushchev for the derivative of a polynomial having all its zeros on the unit circle . The inequality is used to show that equally-spaced points solve a min-max-min problem for the logarithmic potential of such polynomials. Using techniques recently developed for polarization (Chebyshev-type) problems, we s...

0 98.8 F, Respiratory Rate 20/min. His admission labs showed Sodium 138 mEq/L, potassium 5.5 mEq/L, chloride 95 mEq/L, bicarbonate 14 mEq/L, BUN 193 mg/dL, Cr 16 mg/dL, phosphorus 12.4 mg/dL, WBC 7.7 cumm, Hemoglobin 13.8 g/dL, and hematocrit 39.0%, Creatine kinase 2920 mg/dL. Urinalysis revealed large blood, negative protein, specific gravity 1012, WBC 4-10/hpf, RBC>50 / HPF with many RBC cast...

C3bi receptors (CR3) on human polymorphonuclear leukocytes (PMN) bind ligand-coated particles and promote their ingestion. The binding activity of CR3 is not constitutive but is transiently enabled by phorbol esters (Wright, S. D., and B. D. Meyer, 1986, J. Immunol. 136:1759-1764). Our observations indicate that the capacity of CR3 to bind ligand is tightly correlated with the degree of ligand-...

Suppose that K ⊂ IR is either the unit ball, the unit sphere or the standard simplex. We show that there are constants c1, c2 > 0 such that for a set of Fekete points (maximizing the Vandermonde determinant) of degree n, Fn ⊂ K, c1 n ≤ min b∈Fn b 6=a dist(a, b) ≤ c2 n , ∀a ∈ Fn where dist(a, b) is a natural distance on K that will be described in the text. §

The regulatory mechanism of decline in catalytic activity for intestinal lactase (lactase-phlorizin hydrolase, beta-galactosidase) as mammals mature has not been defined. Solubilized intestinal brush-border membranes from adult male rats (greater than 4 months of age, 200-400 g) were examined by high performance liquid Zorbax GF-450 chromatography, subjected to denaturing acrylamide electrophor...
