Measurement of cel l -mediated cytotoxic i ty (CMC) 1 directed to cell surface antigens has been faci l i ta ted by the e laborat ion of a re la t ively simple reproducible test in which ~lCr is released from labeled target cells (1-5). Other invest igators have examined certain facets of the test (6-18) and have appl ied the technique to studies of tumor allograft systems (3-5, 16, 19, 20) and...

Objective. To compare four different dry cow treatments (DCT) and establish their effectiveness in reducing intramammary infections (IIM). Materials and methods. DCTs included systemic tylosin (12g) alone or accompanied by cefapirine intramammary infusions and or an internal teat sealant. A total number of 278 cows at the end of lactation period were randomly assigned to one of 4 dry cow treatm...

Fourteen 8-week-old calves infected with S. typbimurium were fed control and 10 mg/ head/day bambermycins in an 8-week study to determine the effect on quanti ty, prevalence, shedding and susceptibi l i ty of Salmonella. Special precautions were taken to eliminate crosscontaminat ion between infected and uninfected animals on both treatments. Salmonella counts of the homogenized fecal samples w...

Sphingosine 1-phosphate (S1P) induces diverse biological responses in various tissues by activating specific G protein-coupled receptors (S1P(1)-S1P(5) receptors). The biological signaling regulated by S1P(3) receptor has not been fully elucidated because of the lack of an S1P(3) receptor-specific antagonist or agonist. We developed a novel S1P(3) receptor antagonist, 1-(4-chlorophenylhydrazono...

This research is to evaluate the acute and subchronic toxicities of “Kien ty chi thong - HV” granules through oral administration in experimental animals. The toxicity was determined by Litchfield Wilcoxon method Swiss mice. evaluated WHO OECD’s recommendation Wistar rats with doses 1.8 g/kg/day (equal recommended human dose) 5.4 (3 times as high 4 consecutive weeks. As a result, at highest dos...

A scheme for explicit ly representing and using expert knowledge of a procedural k ind is described. The scheme al­ lows the explicit representation of both declarative and proce­ dural knowledge wi th in a unified framework, yet retains all the desirable properties of expert systems such as modular i ty , ex­ planatory capabil i ty, and extendabil i ty. It thus bridges the gap between the proc...

Let C be a closed convex subset of a complete metrizable topological vector space (X ,d) and T : C → C a mapping that satisfies d(Tx,Ty) ≤ ad(x, y) + bd(x,Tx) + cd(y,Ty) + ed(y,Tx) + f d(x,Ty) for all x, y ∈ C, where 0 < a < 1, b ≥ 0, c ≥ 0, e ≥ 0, f ≥ 0, and a+ b + c + e + f = 1. Then T has a unique fixed point. The above theorem, which is a generalization and an extension of the results of se...

Recently P. R. Halmos [S] mentioned a question raised by S. V. Fomin as to whether it follows that two measure preserving transformations are conjugate if they are unitarily equivalent and possess the same entropy. The purpose of this work is to concoct a counterexample to this conjecture. Let X be the unit interval with Borel measurability and Lebesgue measure. Let XXX be the unit square and X...

BACKGROUND To explore if health related quality of life(HRQoL) increased after traditional yoga(TY), mindfulness based cognitive therapy(MBCT), or cognitive behavioral therapy(CBT), in patients on sick leave because of burnout. METHODS Randomized controlled trial, blinded, in ninety-four primary health care patients, block randomized to TY, MBCT or CBT (active control) between September 2007 ...
