This study aimed to the role of PPARs on fat deposition in native crossbred chicken. We studied growth, abdominal, subcutaneous, and intramuscular fat, mRNA expression PPARA PPARG adipose muscle tissues four chicken breeds (CH breed (100% Thai chicken), KM1 (50% CH background), KM2 (25% broiler (BR)). The result shows that BR chickens had higher abdominal than other (p < 0.05) an percentage ...

Recently, Seiberg and Witten (see [SW1], [SW2], [W]) introduced a remarkable new equation which gives differential-topological invariants for a compact, oriented 4-manifold with a distinguished integral cohomology class which reduces mod(2) to the 2nd Steiffel-Whitney class of the manifold. A brief mathematical description of these new invariants is given in the recent preprint [KM1]. Using the...

The Ramsey number R(G1; G2; : : : ; Gn) is the smallest integer p such that for any n-edge coloring (E1; E2; : : : ; En) of Kp; Kp[Ei] contains Gi for some i, Gi as a subgraph in Kp[Ei]. Let R(m1; m2; : : : ; mn):=R(Km1 ; Km2 ; : : : ; Kmn); R(m; n):=R(m1; m2; : : : ; mn) if mi=m for i=1; 2; : : : ; n. A formula is obtained for R(G1; G2; : : : ; Gn). c © 2001 Elsevier Science B.V.

The goal of this paper is to generalize the main results of [KM1] and subsequent papers on metric Diophantine approximation with dependent quantities to the set-up of systems of linear forms. In particular, we establish ‘joint strong extremality’ of arbitrary finite collection of smooth nondegenerate submanifolds of R. The proofs are based on quantitative nondivergence estimates for quasi-polyn...

We refine the techniques of our previous paper [KM1] to prove that the average order of vanishing of L-functions of primitive automorphic forms of weight 2 and prime level q satisfies ∑ f∈S2(q)∗ ords= 1 2 L(f, s) ≤ C|S2(q) ∗| with C = 6.5, for all q large enough. On the Birch and Swinnerton-Dyer conjecture, this implies rank J0(q) ≤ C dim J0(q) for q prime large enough.

A highly sensitive spectroscopic method using dichlorofluorescin (LDCF) was employed to study the rate of electron-transfer reaction in presence of dsDNA, ssDNA and some metal ions and imidazole derivative (N-trans cinnamoyl imidazole).Our results show that both kinds of DNA possess an enzyme-like catalytic activity in oxidative conversion of non fluorescent LDCF to fluorescent DCF. A biphasic ...

Sulfation of ethinyl estradiol (EE) is a major pathway of first pass metabolism in both the intestine and liver. Consequently, we sought to identify the human sulfotransferases (SULTs) involved in the 3-O-sulfation of EE (EE-SULT). Based on the results described herein, cDNA-expressed human cytosolic SULT1A3 and SULT1E1 were identified as low Km isoforms (18.9 and 6.7 nM, respectively) mediatin...

Through dedication and intelligent research, Haldor Topsøe’s name has become synonymous with efficient and profitable ammonia production and has set the standard for ammonia catalysts and technology. We build upon this legacy with the introduction of an ammonia synthesis catalyst that delivers the highest performance ever – KM 111. KM 111 is a magnetite-based catalyst developed for optimal perf...
