background and objectives: the genus johrenia belongs to umbelliferae family and contains five species that are endemic to iran. johrenia paucijuga grows widely in the north-west, west and center of iran. so far, there has been no research about phytochemistry of j. paucijuga. in the present study, phytochemicals of the plants have been isolated and their structures have been elucidated. method...
by application of modern recombinant dna technology, especially the polymerase chain reaction (pcr)/dot-blot hybridization techniques, we have investigated the molecular basis of β-thalassemia from four different regions of iran: central, south-east, south and north. in this study, the dna samples were isolated from patients and for the identification of the mutations, the 6 oligonucleotide pro...
Physiological studies confirm improvement of memory by Olibanum, a resin from Boswellia species, while little is known about the molecular mechanism by which it affects memory performance. Two master transcription factors, CREB-1 and CREB-2, regulate downstream memory-related genes expression, leading to the long-term memory potentiation. This study addresses the effects of Beta-boswellic acid ...
Molecular epidemiology is a subdivision of medical science and epidemiology that emphases on the involvement of potential environmental and genetic risk factors, recognized at the molecular level, to the etiology and avoidance of sickness through populations. This arena has developed from the combination of molecular biology and traditional epidemiological research. Molecular...
Background and purpose: Depression and anxiety affect the outcomes of diabetes treatment, but, it is not yet completely understood how this happens. We used a structural model to assess the relationship between depression and anxiety considering the mediating role of physical activity on treatment adherence and diabetes control. Materials and methods: The present study was conducted using the...
Background and purpose: Hospital infections are common throughout the world. Antibiotic resistance is caused after infectious diseases and hospital infections. Considering the importance of hospital infection and bacteria resistant to antibiotics, this study aimed at investigating the prevalence of β-lactamase enzymes in bacteria isolated from nosocomial infections. Material and Methods: Fi...
in this paper the concepts of fuzzifying β − irresolute functions and fuzzifying β − compactspaces are characterized in terms of fuzzifying β − open sets and some of their properties are discussed.
Objective(s): To analyze the potential influences of propofol on the oxidative stress of H2O2-induced human esophageal squamous cell carcinoma (ESCC) Eca109 cell through mediating the Wnt/β-catenin signaling pathway.Materials and Methods: Eca109 cells were classified into 5 groups: Control group, H2O2 group, Propofol + H2O2 group, Dkk1 (Dickkopf-1, Wnt/β-catenin pathway antagonist) + H2O2 group...
هدف از این تحقیق شناسایی چند شکلی ژن های هورمون رشد (gh)، بتالاکتوگلوبولین β-lg) و pit-1 در یک گله گاو هلشتاین با روش pcr-rflp و بررسی ارتباط آن ها با تولید شیر بود. هورمون رشد نقش مهمی در تنظیم رشد، متابولیسم و شیر دهی ایفا می کند. بتالاکتوگلوبولین پروتئین عمده ی آب پنیر در شیر است که در انتقال و متابولیسم رتینول و اسید های چرب نقش دارد و pit-1 مسئول رشد هیپوفیز و بیان هورمون های مرتبط با آن د...
