lthough the cellular adhesion molecule CD44 is involved in processes ranging from lymphocyte homing to tumor metastasis, it has remained unclear how CD44 transduces the intracellular signals required for such a broad range of activities. On page 755, Okamoto et al. propose a surprising mechanism for CD44 signal transduction: a cytoplasmic domain is cleaved from the protein, after which it trans...

background: the nucleus raphe magnus (nrm) is involved in thermoregulatory processing. there is a correlation between changes in the firing rates of the cells in the nrm and the application of the peripheral thermal stimulus. introduction: we examined the effect of reversible inactivation and excitation of nrm on mechanisms involved in tail blood flow (tbf) regulation in hypothermia. methods: h...

The β-decay of the even-even nucleus 70Kr with Z=N+2, has been investigated at Radioactive Ion Beam Factory (RIBF) RIKEN Nishina Center using BigRIPS fragment separator, ZeroDegree Spectrometer, WAS3ABI implantation station and EURICA HPGe cluster array. Fifteen γ-rays associated into 70Br have identified for first time, defining ten populated states below Eexc=3300 keV. half-life was derived i...

Introduction: In this study the effect of Matricaria recutita extract on acute pain in the presence and absence of flumazenil (antagonist of benzodiazepine) and lesioned paragigantocellularis (PGi) nucleus was investigated. Method: Wistar male rats (250±20 g) were used. Animals were grouped randomly into intact, sham and bilateral lesion of PGi nucleus. Intact and lesioned animals, each...

Broad nervous circuits originate from the hypothalamic arcuate nucleus project to many parts of the brain which are related to pain perception. Insulin receptors have been found in the arcuate nucleus. Since nociception may be affected in type 1 diabetes, the present study aimed to investigate the intra-arcuate nucleus insulin role in pain perception in STZ-induced diabetic and healthy rats. Fo...

long-term complications of retained war fragments in the body are not completely known. also, bullet migration and slow resorption of metals and distortion in some imaging modalities are frequent and well recognized complications but, now we are concerned about neoplastic changes near the retained war fragments. we reviewed the literature on complication of retained war fragments and report our...

conclusions the results revealed that the strains under study could be epidemically related. it seems that an alternative subtyping method is needed to study the relationship among clinical s. sonnei strains and their transmission. here, we reported for the first time, two strains of s. sonnei with a different pcr-rflp pattern for ipah gene. results all shigella isolates were positive for both ...

background and aims: a multiplex transcription-polymerase chain reaction (m-pcr) was developed for direct detection and discrimination between canarypox virus (cpv) and other avian poxvirus (apv). materials and methods: three compatible primer sets were designed for m-pcr amplification of different loci fpv126, fpv140, and fpv167 located at highly conserved apv genes. results: results showed th...
