The genotypes of the melatonin receptor 1A (MTNR1A) were determined by PCR-RFLP in the native Iranian Shall  and karakul breeds of sheep . Blood samples were collected from 60 karakul and 50 Shall breeds. Genomic DNA was extracted based on the Guanidin Thiocyanate-slica gel method. After PCR reaction, PCR products were digested by the Mnl1 restriction enzyme. The MTNR1A locus had two genotypes ...

introduction: in the present work, spontaneous postsynaptic currents were assessed to investigate the postnatal development of excitatory postsynaptic currents in locus coeruleus neurons. methods: in this study, ampa and nmda receptor-mediated spontaneous synaptic currents in the neurons of locus coeruleus were assessed using whole cell voltage-clamp recording during the first three weeks. resu...

introduction: pain as a complex process in central nervous system (cns) has been studied by many researchers. pain is controlled by several cns pathways, one of the most important of which, is the descending noradrenergic system. this system begins from locus coeruleus (lc) nucleus in pons and ends in the spinal cord. in this research, the effect of pain induced by formalin was studied. methods...

background: test anxiety is the cause of weakness of the immune system, reducing the academic efficacy, inhibitor of academic achievement and imposes high costs on society. locus of control is not only how to search information in environment but also is  the way of analyzing it in relation to life events. this study is aimed to determine and compare test anxiety and locus of control in payame ...
