objective(s):bone marrow-derived mesenchymal stem cells (bmscs) have attracted significant interest to treat asthma and its complication. in this study, the effects of bmscs on lung pathology and inflammation in an ovalbumin-induced asthma model in mouse were examined. materials and methods:balb/c mice were divided into three groups: control group (animals were not sensitized), asthma group (an...

the steger and warming flux vector splitting implicit scheme is used to numerically solve two dimensional reynolds averaged navier–stokes (rans) equations governing the vortex induced vibration of a flexible riser laterally supported by a spring and a damper. the k–ε model is used as turbulence model to simulate the turbulent flow in the wake of the riser. to update the new position of the rise...

aqueous (hydrophilic) and chloroform (lipophilic) extracts of nine medicinal plants currently used in traditional medicine, in egypt, to treat some gastrointestinal tract (git) disorders were tested for their gastro-protective effect against the incidence of peptic ulcer. indomethacin-induced ulcer in a rat model was used for this testing. mentha microphylla, brassica oleracea capitata (cabbage...

background and objectives: induced demand in healthcare is referred to as provision of unnecessary services or the patient by health services providers, while the patient is not aware of their unnecessity. apart from being unethical, this practice can potentially disturb the supply and demand balance in the health market, pose financial load on the patient, thread the patient’s health by imposi...

the present study investigated the effects of intra-dentate gyrus microinjection of naloxone (an opioid antagonist) and thioperamide (an antagonist of histamine h3 receptors) in the formalin test in rats. subcutaneous injection of formalin (50 μl, 2.5 %) in the ventral surface of right hind paw produced a biphasic pattern (first phase: 0-5 min and second phase: 15 - 60 min) of licking/biting an...

in this study, the effects cold rolling and annealing parameters during thermomechanical processing of the aisi 201ln stainless steel were investigated. the cast samples were homogenized, hot-rolled and solution-annealed to acquire a suitable microstructure for the subsequent thermomechanical treatment. unidirectional and transverse multi-pass cold rolling at 25, 0 and -15 °c was carried out to...

background: radiation-induced discomfort is frequently observed during pelvic radiotherapy. this study was performed to determine the effect of a green tea tablet to reduce the incidence of radiation-induced diarrhea and vomiting in patients with abdomen and pelvic malignancy. materials and methods: this randomized controlled clinical trial recruited 42 patients with abdomen and pelvic malignan...
