BACKGROUND Nutritional supplements based on the amino acid L-arginine have been hypothesized to improve exercise performance by increasing levels of insulin and growth hormone (GH). Changes of these parameters in response to L-arginine supplementation may clarify the mechanisms underlying its putative physiological effects on physical performance. OBJECTIVE The aim of the study was to evaluat...

Đậu tương là loại cây trồng mẫm cảm với hạn và mặn, do vậy nghiên cứu biện pháp tăng cường khả năng chống chịu mặn của đậu vấn đề đang được quan tâm. Protein DREB nhân tố phiên mã làm biểu hiện các gene liên đến tính tương, tuy nhiên nay còn nhiều ở chưa rõ chức năng. Nghiên này nhằm tạo chuyển phục vụ đánh giá vai trò GmDREB7 đối tương. Các phương biến nạp di truyền, tái sinh, chọn lọc in vitr...

A series of asymmetrically carboxylate-bridged diiron(ii) complexes featuring fluorine atoms as NMR spectroscopic probes, [Fe2(PIM)(Ar(4F-Ph)CO2)2] (10), [Fe2(F2PIM)(Ar(Tol)CO2)2] (11), and [Fe2(F2PIM)(Ar(4F-Ph)CO2)2] (12), were prepared and characterized by X-ray crystallography, Mössbauer spectroscopy, and VT (19)F NMR spectroscopy. These complexes are part of a rare family of syn N-donor dii...

Serum carbohydrate-deficient transferrin (CDT) concentrations and gammaglutamyl transferase (GGT) activities were measured in the fasting serum of healthy male subjects before and after 4 weeks consumption each day of 375 ml wine or 500 ml grape juice. After wine consumption, serum CDT concentrations rose in 38 of 48 individual test procedures, and the mean +/- SEM increased from 17.8 +/- 0.86 ...

Consider any stationary Schroedinger wave equation (SWE) solution ψ(x) for a particle. The corresponding PDF on position x of the particle is pX(x) = |ψ(x)| . There is a classical trajectory x(t) for the particle that is consistent with this PDF. The trajectory is unique to within an additive constant corresponding to an initial condition x(0). However the value of x(0) cannot be known. As an e...

Given a spacelike 2-surface Σ in a spacetime N and a constant future timelike unit vector T0 in R 3,1 , we derive upper and lower estimates of Wang-Yau quasilocal energy E(Σ, X, T0) for a given isometric embedding X of Σ into a flat 3-slice in R 3,1 . The quantity E(Σ, X, T0) itself depends on the choice of X , however the infimum of E(Σ, X, T0) over T0 does not. In particular, when Σ lies in a...

1. General setting Let T be a nonempty set, Σ be the σ -algebra of subsets of T , and μ be a nonnegative σ -additive measure on Σ . We denote by Lp(T , Σ, μ) (or simply Lp(T , μ)) the set of all Σ-measurable functions with values in R or in C for which ∥x(·)∥Lp(T ,μ) =  T |x(t)|p dμ(t) 1/p < ∞, 1 ≤ p < ∞, ∥x(·)∥L∞(T ,μ) = ess sup t∈T |x(t)| < ∞, p = ∞. Put W = {x(·) ∈ Lp(T , μ) : ∥φ(·)x(·)∥L...

In com plexes o f the type [(NC )2H gIIN C FeII(CN )5]4~ which are formed in aqueous mixtures of H g(C N )2 and [Fe(C N )6]4~ both metals are weakly coupled. Optical metal to metal charge transfer (M M CT) excitation from F e11 to Hg" leads to the reduction of Hg" to Hg" an the oxidation of [Fe(C N )6]4~ to [Fe(C N )6]3~. In the complex [(NC)5CoIH g IIC o I(CN )5]6" the metals are strongly coup...

This paper characterizes the possible blow-up of solutions for 3D magneto-hydrodynamics (MHD short) equations. We first establish some ϵ-regularity criteria in Lq,∞ spaces suitable weak solutions, and then together with an embedding theorem from Lp,∞ space into a Morrey type we characterize local behaviors near potential singular point. More precisely, show that if z0=(t0,x0) is point, any r>0 ...
