crohn’s disease (cd) is rarely presented with lower gi bleeding (lgib) which eludes the clinician. a 25-year-old lady with severe rectorrhagia was presented with no history of constipation, diarrhea or abdominal pain. colonoscopy revealed ulcers in the rectum, sigmoid colon, and terminal ileum. crohn’s pathologic features were detected in the terminal ileum. the bleeding was controlled via supp...

in recent years, underactuated nonlinear dynamic systems trajectory tracking, such as space robots and manipulators with structural flexibility, has become a major field of interest due to the complexity and high computational load of these systems. hierarchical sliding mode control has been investigated recently for these systems; however, the instability phenomena will possibly occur, especia...

objective(s): the study aimed to investigate the effects of adrenomedullin (adm) and proadrenomedullin n- terminal 20 peptide (pamp) on angiotensin ii (angii)-stimulated proliferation in vascular smooth muscle cells (vsmcs). materials and methods: thoracic aorta was obtained from wistar rats and vsmcs were isolated from aorta tissues and then cultured. in vitro cultured vsmcs were stimulated wi...

A system of measures allowing to improve the level vehicle services at grain terminal was developed. The composition considered includes following measures: “Grain Terminal” simulation model service vehicles, a program for implementation pre-registration vehicles in terminal, pre-parking, waiting and algorithm vehicular transport management using radio frequency identification (RFID) technology.
