This study was undertaken to determine the roles of individual alpha/beta 1 integrin heterodimers in promoting cellular interactions with the different attachment-promoting domains of laminin (LN). To do this, antibodies to the integrin beta 1 subunit or to specific integrin alpha subunits were tested for effects on cell attachment to LN, to elastase fragments E1-4 and E1, derived from the shor...

BACKGROUND: Embryo implantation requires that uterine epithelium develops competence to bind trophoblast to its apical (free) poles. This essential element of uterine receptivity seems to depend on a destabilisation of the apico-basal polarity of endometrial epithelium. Accordingly, a reorganisation of the actin cytoskeleton regulated by the small GTPase RhoA plays an important role in human ut...

Choriocarcinoma, a highly malignant tumor arising from the trophoblast, comprises a heterogenous population of cells including cytotrophoblasts, intermediate trophoblasts, and syncytiotrophoblasts. In order to investigate trophoblast differentiation, we used centrifugal elutriation to separate cells from the JAr choriocarcinoma cell line according to their size and to further show that the resu...

The requirements approval method is necessary to ensure that the system requirements have been identified in right way and the understanding between the contractor and the client exist. During research conducted is identified that most of the scholars have been working for the requirements definition during the meeting with the client, even they started to initiate the validation by checking wh...

The bioefficacy of a commercial formulation of temephos, Creek against Aedes aegypti larvae was studied in the laboratory. Earthen jars were filled with 10 L tap water each. One g of temephos (Creek) sand granule formulation was added into each earthen jar as recommended by the manufacturer. The final test concentration of Creek was 1 mg a.i./L. One earthen jar was filled with 10 L tap water an...

Characterization of free radical-induced cell injury processes of placenta cells is of vital importance for clinical medicine for the maintenance of intrauterine fetal life. The present study has analyzed cell injury processes in cells of the choriocarcinoma cell line JAR treated with menadione, an anticancer drug, and H(2)O(2) in comparison to osteosarcoma 143B cells using electron microscopic...

In theory, there is no difference between theory and practice; In practice, there is. Abstract This paper describes the design and use of a Java Web Start framework called Initium. Initium generates a jar file that minimizes the number of included classes by performing a static class dependency analysis. It then prompts the programmer for security parameters that enable the programmatic signing...
