BACKGROUND The aim of this study was to examine the invasiveness of first trimester trophoblasts according to the secretion profile of MMP-2 and -9 at different gestational stages, and to test the similarity between primary trophoblast cell-culture and the JAR choriocarcinoma cell-line. METHODS First trimester trophoblasts were divided into two groups: 6-8 weeks (early) and 9-12 w (late) of g...

Three commercially available anaerobic cabinets are described and their performance in relation to one another and to a standard anaerobic jar technique are reported upon from a clinical laboratory.

We aimed to test the associative effects among forages, and between forage concentrates on in vitro digestibility of dry matter neutral detergent fibre using an artificial ruminal fermentation system. The study consisted two assays, which were evaluated three sugarcane, maize silage, Tifton 85 hay under incubation conditions (single feed or all feeds together a jar), sugarcane soybean meal and/...

The Wise Anaerobic Work Station permitted the growth of type cultures of a range of fastidious obligate anaerobes. In the isolation of anaerobic bacteria from clinical specimens the performance equalled that of a standard anaerobic jar incubated for 48 hours, and gave results superior to those obtained when incubation of jar cultures was interrupted at 24 hours. The Wise Anaerobic Work Station ...

This paper describes how to resign Jar files. Jar files (Java archives) are used by technologies (like Java Web Start) to deploy applications that are run with increased privileges. The Jar files are signed with certificates that generally expire after a year. The annual resigning of the files is therefore an event that occurs after the signer has forgotten how resigning is done. Manual resigni...

Java Archive (JAR) file is a popular way to aggregate Java class files and resources into one package for distributing applications and/or libraries. JAR file format is developed based on the popular ZIP file format, while providing a convenient way to organize Java byte code for distribution in the open source community, JAR added extra layer of encapsulation and made it more difficult to tell...

many performance evaluations for ieee 802.11distributed coordination function (dcf) have been previouslyreported in the literature. some of them have clearly indicatedthat 802.11 mac protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. although rts/cts transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
