Previous studies have shown that electrical stimulation (ES) increases blood flow, but the exact mechanisms are not clear. The present study was designed to clarify some of the underlying mechanisms involved in this phenomenon. White adult rabbits Lt.-6 months old were used. Animals were anesthetized by sodium pentobarbital (40 mg/kg, IV) and skin blood flow in the thoracic back was recorde...

abstract stochastic model for synthetic data generation is not available for daily flows of intermittent streams. such a model is required in the planning and operation of structures on an intermittent stream for purposes where short time flow fluctuations are important. in this study a model is developed for such a case. the model consists of four steps: determination of the days on which flow...

Background: Laminar flow ventilation systems were developed to reduce surgical contamination in joint arthroplastyto avoid periprosthetic joint infection (PJI). The goals of this study are to evaluate the cost-effectiveness and economicviability of installing and maintaining a laminar flow system in an operating room.Methods: A Monte Carlo simulation was used to evaluate the c...

results the mean heart rate values were significantly less in the sevoflurane group (p value < 0.05) at 25 minutes after the surgery. the mean blood pressure in the isoflurane group was significantly higher compared with the sevoflurane group in 10, 20 and 30 minutes after the surgery (p values = 0.0131, 0.0373 and 0.0028, respectively). these differences were clinically unimportant because hea...

this paper seeks to emphasize the flow variability in the calnistea catchment by analyzing the local physiographic factors. the research has shown that the amount of precipitation that falls to the ground is low, the rocks in the region are soft, but highly permeable, gradients are gentle in most of the territory and vegetal cover is sparse and therefore cannot hold important amounts of water. ...

objective: leishmaniasis is one of the significant causes of morbidity and mortality in several countries. it is an important problem in endemic areas such as iran. the goal in treatment of leishmaniasis is to reduce the disease period and leave no evidence of any remaining scars or lesions. a derivative of artemisinin is artemether. scientists believe that the strong action of artemether again...

rock has been advantageously employed in hydraulic structures such as rockfill dams, gabion weirs and drain works. one rockfill dam applications can be flood control in wa-tershed management. the objectives of building rockfill detention dams are flow storage for a specific period and lowering of the outflow hydrograph. as this type of dam consists of coarse particles, seepage flow will deviate...

background preeclampsia is one of the leading causes of maternal mortality and morbidity. its prevalence varies between 10-25% among high-risk pregnant patients. objectives the aim of this study was to determine whether treatment with acetylsalicylic acid (asa) reduces the incidence of preeclampsia among pregnant women with abnormal uterine artery flow. patients and methods in this double-blind...
