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 the present study, both lamprey GnRH-I and -III stimulated steroidogenesis and induced ovulation in adult female sea lampreys during their final reproductive stage. One injection of lamprey GnRH-III at 0.1 or 0.2 microg/g lamprey stimulated plasma estradiol levels in lampreys held at each of three water temperatures, 13 degrees , 17 degrees , and 19 degrees , corresponding to increasing stag...

Tubulobulbar Complexes (TBCs) are actin-rich structures formed between Sertoli-cells and spermatids at the time of sperm release. The main functions of the TBCs are to remove excess spermatid cytoplasm and acrosomal contents, internalize and recycle junctional complexes by endocytosis prior to spermiation. However, in addition to recycling some of the molecules undergo lysosomal degradation. Th...
