background: functional gastrointestinal disorders (fgids) entail several distinct conditions that collectively account for a sizeable proportion of patients complaining of abdominal pain. physicians' awareness is fundamental to avoid unnecessary evaluations and to alleviate stress-related problems. this study aimed to assess the relative frequencies of fgids and related categories in a selected...

the phytoplankton structure and dynamics were analysed in relation to abiotic variables inpaso de las piedras reservoir, argentina. phytoplankton driving forces were explored using a functionalapproach. a total of 15 functional groups were identified among which d, p, h1, f, j and c were the mostimportant. a canonical variate analysis indicated that the categorization of the species in function...

anthocoris nemoralis (f.) (hemiptera: anthocoridae) is one of the most prominent predators of the pear psylla, cacopsylla pyricola (forster) (hemiptera: psyllidae) and is considered as a biological control agent against this pest. in order to investigate the effects of plant varieties on predation of c. pyricola by a. nemoralis, the functional response of both the sexes of a. nemoralis to pear ...

introduction: the selection of   optimal treatment of obstructive nephrouropathy requires information about the functional status of each kidney. nuclear renal scanning objectively measure differential renal function, multiple studies have demonstrated the role of assessment of renal perfusion and gfr with triphasic ct. the aim of this study is to assess the role of ct based on renal parenchyma...

the writing skill is often perceived as the most difficult language skill since it requires a higher level of productive language control than other skills (celce-murcia & olshtain, 2000). the present study introduced a discourse-based framework for the teaching of writing on the basis systemic functional linguistics (sfl). to this end, 60 students majoring in teaching english as a foreign ...

in this article differential transformation method (dtms) has been used to solve neutral functional-differential equations with proportional delays. the method can simply be applied to many linear and nonlinear problems and is capable of reducing the size of computational work while still providing the series solution with fast convergence rate. exact solutions can also be obtained from the kno...

background: we aimed to evaluate the effects of pimpinella anisum (anise) from apiaceae family on relieving the symptoms of postprandial distress syndrome (pds) in this double-blind randomized clinical trial. materials and methods: totally, 107 patients attending the gastroenterology clinic, aged 18-65 years, diagnosed with pds according to rome iii criteria and signed a written consent form we...

background: before the year 1950 treatment of myocardial infarction patients was complete bed rest for several weeks and reduces physical activity for several months. cardiac rehabilitation based on exercise training reduces the effects of deconditioning of bed rest. the primary purpose of this study was to determine the methods and means of prevention and treatment of coronary artery disease. ...

introduction: spinal cord injury (sci) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. after severe spinal cord injury, astrocytes of the central nervous system (cns) become reactive astrocytes, and play the main role of glial scar formation. the scar is a major obstacle t...

to explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. the electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. the graphene with the most stable configuration defect named as sw defect is considered. the hig...
