conclusions the increasing cell toxicity, apoptosis-inducing effects and decreasing telomerase activity may play an important role in the valproic acid and radiation mechanism. the current survey suggested that it is likely beneficial to combine valproic acid and gamma radiation to treat breast cancer. results combination of valproic acid and gamma radiation increased significantly cell toxicit...
according to cheng (1999), in recent esl/efl literature, asian (especially east asian) learners of english as a foreign/second language have been arguably reported as reticent and passive learners. the most common allegations are that these students are reluctant to participate in classroom discourse; they are unwilling to give responses; they do not ask questions; and they are passive and over...
Like interleukin 2 (IL-2), interferon gamma (IFN-gamma) is an early response gene in T cells and both are prototypical T helper cell type 1 (Th-1) lymphokines. Yet IL-2 and IFN-gamma production are independently regulated, as demonstrated by their differential expression in certain T cell subsets, suggesting that the regulatory elements in these two genes must differ. To explore this possibilit...
Agouti-related peptide (AgRP) neurons of the hypothalamus play a key role in regulating food intake and body weight, by releasing three different orexigenic molecules: AgRP; GABA; and neuropeptide Y. AgRP neurons express various G protein-coupled receptors (GPCRs) with different coupling properties, including Gs-linked GPCRs. At present, the potential role of Gs-coupled GPCRs in regulating the ...
The energy spectra of TeV gamma-rays from blazars, after being corrected for intergalatic absorption in the Extragalactic Background Light (EBL), appear unusually hard, a fact that poses challenges to the conventional models of particle acceleration in TeV blazars and/or to the EBL models. In this paper we show that the internal absorption of gamma-rays caused by interactions with dense narrow-...
BACKGROUND In coeliac disease (CD) mucosa, the histological lesion is associated with marked infiltration of T helper cell type 1 (Th1) cells. However, the molecular mechanisms which regulate Th1 cell differentiation in CD mucosa are unknown. AIMS To analyse expression of transcription factors which control the Th1 cell commitment in CD. PATIENTS Duodenal mucosal samples were taken from unt...
Background: Identifying the risk factors of recurrence of a disease is important both for physicians and patients. Analyzing the first recurrence may lead to an inaccurate evaluation of risk factors as it may not reflect the history of disease completely and may result in the loss of some valuable information. This study was aimed to analyze the time up to the recurrent relapses of bipolar diso...
background: summer savory (satureja hortensis l.) is one of the most important medicinal and spice plants cultivated in many parts of the world. objective: a greenhouse experiment was conducted to study the effects of feso4 and citric acid application on the morphological traits and essential oil content and its component, gamma-terpinene in s. hortensis. methods: feso4 in four levels (0, 3, 4 ...
Tyzio et al. (Reports, 15 December 2006, p. 1788) reported that maternal oxytocin triggers a transient excitatory-to-inhibitory switch of gamma-aminobutyric acid (GABA) signaling during labor, thus protecting the fetal rat brain from anoxic injury. However, a body of evidence supports the possibility that oxytocin is released from the fetal pituitary during delivery, not only from the mother, p...
