Observations have been made on the response, in vitro, of cultured and freshly dissociated cells to mechanical deformation. Large numbers of individual cells were studied by means of a special culture chamber bounded by two parallel glass coverslips whose spacing could be reduced from 140 to 2 microns in steps of roughly 0.5 micron. The degree of deformation required for herniation of the cell ...

the mathematical properties of nano molecules are an interesting branch of nanoscience forresearches nowadays. the periodic open single wall tubulene is one of the nano moleculeswhich is built up from two caps and a distancing nanotube/neck. we discuss how toautomatically construct the graph of this molecule and plot the graph by spring layoutalgorithm in graphviz and netwrokx packages. the sim...

Introduction: Consumption of morphine, during pregnancy, in addition to inducing defects in the mother’s nervous system function, caused defects or delays in the formation and evolution of embryonic visual system. In the present study, changes in lens development were assessed in embryos exposed to morphine in utero. Methods: Female Wistar rats (250-300 g) were mated with male rats and pregnanc...

Objective: To understand the clinical characteristics of patients with embryonic posterior cerebral artery and its correlation abnormal vascular development. Methods: The data 396 confirmed by magnetic resonance angiography (MRA) computed tomography (CTA) were analyzed. Results: Two-hundred had manifestations circulation ischemia, including recurrent dizziness, vertigo, tinnitus; 45 headaches, ...

BACKGROUND In assisted reproduction procedures, we need to develop and enhance new protocols to optimize sperm selection. The aim of this study is to evaluate the ability of the Z potential technique to select sperm with intact DNA in non-normospermic patients and evaluate the impact of this selection on embryonic development. METHODS We analyzed a total of 174 human seminal samples with at l...

OBJECTIVE To determine the relationship between paternal body mass index (BMI), embryo development and pregnancy, and live birth outcomes after assisted reproductive technology (ART). DESIGN Retrospective analysis of ART cycles. SETTING Major assisted reproduction center. PATIENT(S) Three hundred five couples undergoing ART in a private fertility clinic. INTERVENTION(S) No intervention ...
