Background
We examined the effect of four weeks of ??-alanine supplementation on isometric endurance of the knee extensors at 45% maximal voluntary isometric contraction (MVIC).Methods
Thirteen males (age 23?±?6 y; height 1.80?±?0.05?m; body mass 81.0?±?10.5?kg), matched for pre-supplementation isometric endurance, were allocated to either a placebo (n?=?6) or ??-alanine (n?=?7; 6.4?g·d-1 over 4?weeks) supplementation group. Participants completed an isometric knee extension test (IKET) to fatigue, at an intensity of 45% MVIC, before and after supplementation. In addition, two habituation tests were completed in the week prior to the pre-supplementation test and a further practice test was completed in the week prior to the post-supplementation test. MVIC force, IKET hold-time, and impulse generated were recorded.Results
IKET hold-time increased by 9.7?±?9.4?s (13.2%) and impulse by 3.7?±?1.3 kN·s-1 (13.9%) following ??-alanine supplementation. These changes were significantly greater than those in the placebo group (IKET: t (11)?=?2.9, p ??0.05; impulse: t (11)?=?3.1, p????0.05). There were no significant changes in MVIC force in either group.Conclusion
Four weeks of ??-alanine supplementation at 6.4?g·d-1 improved endurance capacity of the knee extensors at 45% MVIC, which most likely results from improved pH regulation within the muscle cell as a result of elevated muscle carnosine levels. 相似文献85.
A multiplicative secret sharing scheme allows players to multiply two secret-shared field elements by locally converting their shares of the
two secrets into an additive sharing of their product. Multiplicative secret sharing serves as a central building block in
protocols for secure multiparty computation (MPC). Motivated by open problems in the area of MPC, we introduce the more general
notion of d-multiplicative secret sharing, allowing to locally multiply d shared secrets, and study the type of access structures for which such secret sharing schemes exist. 相似文献

Nanoimprint lithography (NIL) is viewed as an alternative nanopatterning technique to traditional photolithography, allowing micrometer‐scale and sub‐hundred‐nanometer resolution as well as three‐dimensional structure fabrication. In this Research News article we highlight current activities towards the use of NIL in patterning active or functional materials, and the application of NIL in patterning materials that present both chemistry and structure/topography in the patterned structures, which provide scaffolds for subsequent manipulation. We discuss and give examples of the various materials and chemistries that have been used to create functional patterns and their implication in various fields as electronic and magnetic devices, optically relevant structures, biologically important surfaces, and 3D particles. 相似文献

This study evaluates the influence of particle size, PEGylation, and surface coating on the quantitative biodistribution of near‐infrared‐emitting quantum dots (QDs) in mice. Polymer‐ or peptide‐coated 64Cu‐labeled QDs 2 or 12 nm in diameter, with or without polyethylene glycol (PEG) of molecular weight 2000, are studied by serial micropositron emission tomography imaging and region‐of‐interest analysis, as well as transmission electron microscopy and inductively coupled plasma mass spectrometry. PEGylation and peptide coating slow QD uptake into the organs of the reticuloendothelial system (RES), liver and spleen, by a factor of 6–9 and 2–3, respectively. Small particles are in part renally excreted. Peptide‐coated particles are cleared from liver faster than physical decay alone would suggest. Renal excretion of small QDs and slowing of RES clearance by PEGylation or peptide surface coating are encouraging steps toward the use of modified QDs for imaging living subjects. 相似文献

Vein of Galen aneurysmal malformation (VGAM) is a rare, intracranial vascular anomaly that, until recently, has usually been diagnosed postnatally. Today, however, with the advances in high-resolution ultrasonography and colour Doppler, prenatal diagnosis is relatively easy. Due to novel intravascular embolization techniques, the prognosis of neonates with VGAM has markedly improved. A healthy infant with normal neurodevelopmental and cardiovascular status is now a reality. For the best outcome, however, careful planning of the appropriate time, mode, and place of delivery should be undertaken. To achieve this goal, in utero prognostic factors should be determined. This report illustrates, for the first time, prenatal ultrasonographic indices that may predict the outcome in two cases with a prenatal diagnosis of VGAM. The indices included mapping of intracranial feeding arteries, assessment of the width of the straight sinus, assessment and measurement of flow in the straight sinus, existence of 'steal' retrograde aortic flow, and the appearance of high-output cardiac state. By using these prenatal ultrasonographic parameters, fetal outcome may be predicted and appropriate management decided upon. 相似文献
