background gastric dysplasia (gd) is a precursor lesion of gastric adenoâ­carcinoma. intestinal type gastric carcinoma commonly shows microsatellite instability (msi) and the diffuse type is associâ­ated with down regulation of e-cadherin. her-2/neu is over-expressed in some cases of gastric cancer. in this study, msi and expression rates of her-2/neu and e-cadherin in gd were evaluated. me t h...

In adult songbirds, seasonal changes in photoperiod and circulating testosterone (T) stimulate structural changes within the neural song control circuitry. The mechanisms that control this natural plasticity are poorly understood. To determine how quickly and in what sequence the song nuclei respond to changing daylength and circulating T, we captured 18 adult male white-crowned sparrows and ke...

OBJECTIVE The purpose of our study is to investigate the relationship between IL-1β -31C/T (rs1143627) and -511T/C (rs16944) polymorphisms and the preeclampsia (PE), and analyze the Linkage disequilibrium (LD) and haplotype frequency of the two polymorphism loci. METHODS Polymorphisms at -31C/T and -511T/C of IL-1β were genotyped with the method of polymerase chain reaction-restriction fragme...

One enigma in tumor immunology is why animals bearing malignant grafts can reject normal grafts that express the same nonself-antigen. An explanation for this phenomenon could be that different T cell clones react to the normal graft and the malignant cells, respectively, and only the tumor-reactive clonotypes may be affected by the growing tumor. To test this hypothesis, we used a T cell recep...

The LD and SD antigens of the major histocompatibility complex subserve differential roles in the induction of the proliferative phase in mixed lymphocyte culture and in the cytotoxic reaction seen in cell-mediated lympholysis. The present study suggests that they also behave differently in the neonatal induction of tolerance. SD antigens appear to induce tolerance in the cytotoxic T lymphocyte...

Science and engineering research increasingly relies on activities that facilitate research but are not currently rewarded or recognized, such as: data sharing; developing common data resources, software and methodologies; and annotating data and publications. To promote and advance these activities, we must develop mechanisms for assigning credit, facilitate the appropriate attribution of rese...
