The objective of the present study was to investigate the time to fatigue and compare the fatiguing condition among the three heads of the triceps brachii muscle using surface electromyography during an isometric contraction of a controlled forceful hand grip task with full elbow extension. Eighteen healthy subjects concurrently performed a single 90 s isometric contraction of a controlled forc...

This is a retrospective analysis of the clinical effects of transplant of mesenchymal stem cells (MSCs) derived from human umbilical cord-derived MSCs (hUC‑MSCs) for the treatment of osteonecrosis of the femoral head (ONFH). The biological characteristics of hUC-MSCs were assessed using flow cytometry. Nine eligible patients were enrolled in the study as they adhered to the Association Research...

In this work, we consider deterministic two-way multi-head automata, the input heads of which are nondeterministically initialised, i. e., in every computation each input head is initially located at some nondeterministically chosen position of the input word. This model serves as an instrument to investigate restricted nondeterminism of two-way multi-head automata. Our result is that, in terms...

Sperm morphometry is a part of the semen analysis based on CASA technology and has shown a big role in the prediction of male fertility. This analysis implies the use of stain techniques, although it has been shown that staining can make dramatic changes in the cell morphometry in different species. The aim of the present work was to evaluate the differences in sperm morphometry in Alpaca, intr...

Given a rectangle A and a set S of n points in A, the maximum empty rectangle problem is that of finding a largest-area rectangle which is contained in A. has its sides parallel to Ihose ofA. and does Dot contain any of the points in S. This Dote describes an efficient algorithm for solving this problem.

It appears that hyaluronate is associated with cell migration and the chondroitin sulphates with differentiation during morphogenesis of the chick embryo. The aim of this study was to see if such a correlation could be made for chondrocranium morphogenesis. Specifically, the purpose of this study was to determine the proportion of extracellular matrix (ECM) to cell area and total head mesenchym...

OBJECTIVE Conventional whole-head MEG systems have fixed sensor arrays designed to accommodate most adult heads. However arrays optimised for adult brain measurements are suboptimal for research with the significantly smaller heads of young children. We wished to measure brain activity in children using a novel whole-head MEG system custom sized to fit the heads of pre-school-aged children. M...

The statistical technique like confidence interval (CI) is used to determine the confidence limits of water head over lake tapping site of Koyna Dam (India, Maharashtra) from water level data taken from government of Maharashtra 2000-2010, which helps in future forecasting. It is the statistical technique which gives the Probable Value of the water head in the relative month. By studying these ...

• Inflorescence architecture is important to angiosperm reproduction, but our knowledge of the developmental basis underlying the evolution of inflorescence architectures is limited. Using a phylogeny-based comparative analysis of developmental pathways, we tested the long-standing hypothesis that umbel evolved from elongated inflorescences by suppression of inflorescence branches, while head e...

We used a novel stopped-flow/rapid-freezing machine to prepare the transient intermediates in the actin-myosin adenosine triphosphatase (ATPase) cycle for direct observation by electron microscopy. We focused on the low affinity complexes of myosin-adenosine triphosphate (ATP) and myosin-adenosine diphosphate (ADP)-Pi with actin filaments since the transition from these states to the high affin...
