In Thailand, ceramic jars (135-200 liters) covered by aluminum lids commonly are used to store water for household use. In laboratory cages, gravid female Aedes aegypti (L.) were able to enter and oviposit in a covered water jar. Although the aluminum lid was not a complete barrier to gravid females, it reduced the number of eggs oviposited by 77%. A vertically oriented foam rubber ring which w...

The objective of this work is studying the use of chemicals to enhance primary treatment in municipal wastewater treatment plants, thereby reducing the cost of the secondary treatment stage. Jar tests using chemicals, polymers and sea water have been conducted to determine the best performing chemicals, alone and in combinations. The process performance parameters studied were pH, type and dosa...

This study aims to assess the applicability of quantitative PCR (qPCR) for removal studies of adenovirus, coxsackievirus, echovirus and Cryptosporidium by water treatment processes. Bench-scale coagulation jar tests were performed using the enteric viruses and Cryptosporidium. Standard methods (conventional cell-culture methods for the viruses and an immunofluorescence assay (IFA) for Cryptospo...

Embryo implantation involves adhesion of trophoblast cells to the epithelial lining of the endometrium. Using an in-vitro model to simulate this initial interaction, we previously reported that attachment of human trophoblast-like JAR spheroids to human uterine epithelial RL95-2 cells provokes a Ca(2+) influx in RL95-2 cells depending on apically localized integrin receptors. Here, we demonstra...

We aimed in this experiment to compare the growth characteristics of Spirulina, which was cultivated in different culture vessels under greenhouse condition. Three types of culture vessels, i.e. transparent jars, polyethylene bags and raceway ponds, were used in the experiment. The jar cultures supported higher cell densities due to their higher culture temperature compared to the others. The d...

Agent-oriented techniques characterize an exciting new way of analyzing, designing and building complex software systems in real time world. These techniques have the prospective to significantly improve current practice in software engineering and to extend the range of applications that can feasibly be tackled. The Agent Oriented Programming & Software Engineering is being focused to design d...

Notch signaling pathways play important roles in cell fate and many diseases, including preeclampsia, the dysregulation of which may be the main cause of maternal mortality. This study aimed to investigate the roles of Notch2 and Notch3 in proliferation and invasion in trophoblast cell lines (BeWo and JAR). Small hairpin RNAs targeting Notch2/Notch3 and Notch2/Notch3-overexpression vectors were...

BACKGROUND Meningococcal factor H binding protein (fHbp) is a promising vaccine candidate. Anti-fHbp antibodies can bind to meningococci and elicit complement-mediated bactericidal activity directly. The antibodies also can block binding of the human complement down-regulator, factor H (fH). Without bound fH, the organism would be expected to have increased susceptibility to bacteriolysis. Here...
