the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...

objective: endothelial progenitor cells (epcs) have a potential application for cell therapy, however, their biological nature is not well-understood. epcs also possess some stemness features, such as their clonogenicity and differentiation capacity. the main aim of this study was to evaluate the expression of certain transcription factors regulating self-renewal property of stem cells. materia...

congenital factor xiii deficiency is a very rare bleeding disorder, but because of the high rate of consanguineous marriages, it is common in sistan and baluchestan province of iran. the discovery of promoter hypermethylation of numerous mirnas in human diseases has demonstrated an epigenetic mechanism for aberrant mirna expression. the present study has analyzed methylation and expression stat...

background: hoxa11 and hoxa10 are expressed in endometrium throughout the menstrual cycle and show a dramatic increase during the mid-luteal phase at the time of implantation. the expression of these genes is decreased in women with myomas. objective: to determine whether myomectomy would reverse hoxa11 and hoxa10 expression, we evaluated the transcript levels of these genes in the endometria o...

background: salivary gland tumors (sgt) are rare lesions with uncertain histopathology. one of the major signaling pathways that participate in the development of several tumors is protein kinase a. in this pathway, glycogen synthase kinase β (gsk3β) and camp responsive element binding protein (creb3) are two genes which are supposed to be down regulated in most human tumors. the expression lev...

suicide is a major public health concern, with approximately one million people committing suicide world-wide each year .risk factors for suicidal behavior include, psychiatric and medical illness, impulsivity, aggression, alcohol and drug abuse specially stimulants, and  stress. neurobiological, brain mappings and biochemical studies have revealed that suicide victims experiencing a large numb...

Plants encounter various stresses such as drought and salinity which adversely affect growth, development and crop productivity. The expression of the genes Delta -1- pyr-roline – 5 - carboxylate synthetase (P5CS) and Betaine aldehyde dehydrogenase (BADH) extends throughout various protec-tive mechanisms in plants and allows them to adapt to unfavorable environmental condi-tions. P5CS and BADH ...
