    Background: Different factors, such as personality and psychological characteristics, are effective in the self-care and control of diabetes. This study aimed at determining the effect of educational intervention based on locus of control structure of attribution theory on the self-care behavior of patients with type II diabetes.    Methods: This was a quasi-experi...

It is a well-known fact that routing metrics play a crucial part in the performance of wireless mesh networks (WMN). When routing protocols are implemented, the routing metrics are assigned to different paths. It calculates the best path to predict the best routing path. They are integrated in routing protocols to improve WMNs efficiency in terms of reliability, latency, throughput, error rate ...

A simple, sensitive, and selective colorimetric biosensor for the detection of the malarial biomarkers Plasmodium vivax lactate dehydrogenase (PvLDH) and Plasmodium falciparum LDH (PfLDH) was demonstrated using the pL1 aptamer as the recognition element and gold nanoparticles (AuNPs) as probes. The proposed method is based on the aggregation of AuNPs using hexadecyltrimethylammonium bromide (CT...

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: pain as a complex process in the cns has been extensively studied by many researchers. it has been found that pain is controlled by certain pathways in the cns, one of most important of which is the descending noradrenergic system. the pathway begins with locus coeruleus (lc) nucleus and ends in the spinal cord. in this study, formalin test was used as a chemical and tonic pain te...

introduction: the effects of electromagnetic fields on biological organisms have been a controversial and also interesting debate over the past few decades, despite the wide range of investigations, many aspects of extremely low frequency electromagnetic fields (elf/emfs) effects including mechanism of their interaction with live organisms and also their possible biological applications still r...

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...
