It is widely accepted that a congener-specific analysis of polychlorinated biphenyls (PCBs), rather than traditional Aroclor equivalent total PCB analysis, is required for risk assessment. This is based on the fact that environmental processes alter the original distribution of PCB congeners in Aroclors and that toxicity varies considerably among the congeners with dioxin-like PCBs (dl-PCBs) ge...

An interesting immunoactive peptide, FK-156, has been isolated from the fermentation broth of Streptomyces olivaceogriseus sp. nov. and Streptomyces violaceus. The compound was purified by column chromatography with activated carbon, ion exchange Sephadex and cellulose powder. FK-156, obtained as white powder, exhibits a wide variety of immunostimulatory activity in vivo and in vitro with exper...

The influence of additives on the structural behaviour cement-stabilised rammed earth was investigated through an experimental programme based 13 different mixes with varying cement contents (6, 8 and 10% by weight) three types (superplasticiser, air-entraining agent (AEA) hardening accelerator). In total, 156 specimens were fabricated tested at 7 28 days in order to compare their compressive s...

it has been well documented that preeclampsia (pe) has a common etiological background, but little is known about its linkage at the molecular level.non- coding rnas are critical posttranscriptional regulators ofgene expression.  this study was performed to determine whether peis associated with alterations in placental non-codingrnas expression. microrna(mir)-155-5p and long non-coding rna (ln...

micrornas (mirnas) are a class of small non coding regulatory rnas that have key functions in multiple cell processes. deregulation of these tiny mirnas are involved in various human diseases. mir-155 is one of the multifunctional mirna that its over-expression has been found to be associated with different kinds of cancer such as leukemia, breast and colon cancers. it is thought that deregulat...

BACKGROUND Novel strategies are needed to increase retention in prevention of mother-to-child HIV transmission (PMTCT) services. We have recently shown that small, incremental cash transfers conditional on attending clinic resulted in increased retention along the PMTCT cascade. However, whether women who receive incentives to attend clinic visits are as adherent to antiretrovirals (ARV) as tho...

CTL derived from (C3H x B6.K1)F1 animals were sensitized against L cells that express the transfected gene product Q10d/Ld. These CTL were highly crossreactive against three other class I molecules, H-2Kbm1, H-2Ld, and H-2Kd. In an attempt to define this crossreactive epitope it was noted that between 25 and 39% of amino acids in the alpha helices and central beta strands of these three molecul...

The major purpose of our research is to study cooperative planning for multi-agent system in time-critical environment. The RoboCup simulator league is the most interesting target for our research. Each agent of the team 11monkeys is realized as an autonomous agent that has two sets of rules, namely state dependent rules and position speciied rules. We call the former dynamic role and the latte...
