background the improvement of self-caring and self-efficacy behaviors is vital in the successful management of asthma. objectives the aim of the research is to determine the relation between self-efficacy of asthma control and quality of life in iranian asthmatic patients. patients and methods this research represents a descriptive-analytical study. the 257 asthmatic patients referred to the cl...
Adult stem cells continuously undergo self-renewal and generate differentiated cells. In the Drosophila ovary, two separate niches control germ line stem cell (GSC) self-renewal and differentiation processes. Compared to the self-renewing niche, relatively little is known about the maintenance and function of the differentiation niche. In this study, we show that the cellular redox state regula...
objective: cd133+ umbilical cord blood cells were identified as a hematopoietic stem cell which has the capacity for extensive self-renewal and differentiation. the aim of this study was to identify the effect of staurosporine (sts), a wellknown protein kinase inhibitor on differentiation of cd133+ cells into neural cells. materials and methods: cd133+ cells were enriched by immunomagnetic bead...
Stem cell – like tumor propagating cells self-renew to drive clonal expansion or differentiate into post-mitotic without tumorigenic potential in squamous carcinomas. This fate choice is governed by a transcriptional network comprised of SOX2-PITX1-TP63 driven self-renewal and KLF4 dependent differentiation circuits. Yet, how stem switch from remains elusive. Here, we report that this bi-stable...
If both waking and dreaming consciousness are functional, their de-differentiation would be doubly detrimental. Differentiation between waking and dreaming is achieved through neuromodulation. During dreaming, without external sensory data and with mesolimbic dopaminergic input, hyper-cholinergic input almost totally suppresses the aminergic system. During waking, with sensory gates open, amine...
objective: one way of improving the quality of life is to eliminate its barriers. selfhandicapping is a form of problematic behavior, which investigating its effect on the quality of life is of great importance. the present study aimed to examine the relationship of selfhandicapping with the quality of life in primary students. methods: this research is a correlational that condoucted on stude...
