Background: In vitro maturation can have deleterious effects on spindle formation and proper chromosome alignment in human oocytes and can be profoundly affected by culture conditions. This study compared the spindle presence and location with the maturation rate Abstracts of the 12th Royan International Congress on Reproductive Biomedicine 3 1 International Journal of Fertility & Sterility (IJ...

purpose: to assess the histopathological and immunohistochemical features of orbital spindle cell tumors. methods: a descriptive, retrospective study was performed on 63 pathology reports on all types of orbital spindle cell tumors at the pathology department of farabi hospital between 1995 and 2005. immunohistochemistry studies for different markers, such as smooth muscle actin, desmin, s100 p...

A question of major importance in the auto industry concerns the modeling and improved design of vehicle tires. Tire performance affects the handling performance of the automobile. Many of the variables on which tire performance depends can be calculated from the load and deflection of the spindle in the suspension system for each wheel. The question of tire performance thus becomes a question ...

The mitotic spindle drives chromosome movement during mitosis and attaches to chromosomes at dedicated genomic loci named centromeres. Centromeres are epigenetically specified by their histone composition, namely the presence of the histone H3 variant CENP-A, which is regulated during the cell cycle by its dynamic expression and localization. Here, we combined biochemical methods and quantitati...

Dimensional accuracy in machined parts depends on the precision of spindle, which is highly affected by applied forces, itself. This precision of spindle becomes more serious when it is used for a period of long times. Therefore, stress and strain analysis of spindle is very important in the behavior and preservation of its precision. In this paper, the forces applied to the spindle of a turnin...

The paper presents the compliance errors compensation technique for industrial robots, which are used in milling manufacturing cells. under external loading, which is based on the non-linear stiffness model. In contrast to previous works, it takes into account the interaction between the milling tool and the workpiece that depends on the end-effector position, process parameters and cutting con...

abstract gastrointestinal mesenchymal tumors are a group of tumors originating from the mesenchymal stem cells of the gi tract. digestive tract schwannomas are rare mesenchymal tumors which occur most frequently in the stomach. we report a 56-yearold woman who was examined endoscopically for dyspepsia which she had suffered from since 3 years ago. around gastric antral mass was seen. surgical r...

background: the aim of this study was to assess effects of cysteamine as an anti-oxidant on rate of in vitro maturation of oocyte and determination of its effects on spindle size and shape. methods: pre-mature mice were primed with pregnant mare stimulating gonadotrophin (pmsg) and germinal vesicle (gv) stage oocytes were obtained 48 h after. the oocytes were cultured in tissue culture medium (...
