background: the aim of the present study was to evaluate how left ventricular twist and torsion are associated with sex between sex groups of the same age. materials and methods : twenty one healthy subjects were scanned in left ventricle basal and apical short axis views to run the block matching algorithm; instantaneous changes in the base and apex rotation angels were estimated by this algor...

at the present study, different properties of sarin with the formula [(ch3)2cho]ch3pof was studiedin gas phase. geometrical optimizations of sarin, single point calculation, nmr and electricalparameters were carried out in gas phase with the hartee -fock method coupled to 6-31g* basis setsfor all atoms. the results obtained from a comparison between tables and charts came up fordiscussion and a...

microtubules, the active filaments with tubular shapes, play important roles in a wide range of cellular functions, including structural supports, mitosis, cytokinesis, and vesicular transport, which are essential for the growth and division of eukaryotic cells. finding properties of microtubules is one of the main concerns of scientists. this work helps to obtain mechanical properties of micro...

BACKGROUND The current study investigated the analgesic effect of the Toll-like receptor 4 (TLR4) specific antagonist TAK-242 on neuropathic pain in rats and its underlying mechanism. METHODS A total of 132 adult Sprague-Dawley (SD) rats were randomly divided into four groups: the sham operation group, the neuropathic pain model group, the TAK-242 low-dose treatment group, and the TAK-242 hig...
