“ Corkscrew ” vs . “ tank - treading ” propulsion of spirochetes .
Submitted for the DFD10 Meeting of The American Physical Society “Corkscrew” vs. “tank-treading” propulsion of spirochetes. ALEXANDER LESHANSKY, Department of Chemical Engineering, Technion-IIT, Haifa, Israel, ODED KENNETH, Physics Department, Technion-IIT, Haifa, Israel — We consider the potential mechanism of spirochete propulsion driven by twirling of the outer cell surface coupled to counte...
متن کاملCorkscrew collaterals in atherosclerosis obliterans
Marked calcifications in the femoral artery obscured imaging of the artery in computed tomography (CT) and duplex ultrasonography. The presence of corkscrew collateral arteries in patients with Atherosclerosis obliterans (ASO) indicates total artery occlusion.

Since the 1960s, several controlled, prospective, epidemiological studies have reported emotional distress as a major risk factor for the onset and worsening of coronary heart disease (CHD) [1]. The Interheart study, a...
متن کاملSegmentation of Vessels: The Corkscrew Algorithm
Medical imaging is nowadays much more than only providing data for diagnosis. It also links ‘classical’ diagnosis to modern forms of treatment such as image guided surgery. Those systems require the identification of organs, anatomical regions of the human body etc., i. e. the segmentation of structures from medical data sets. The algorithms used for these segmentation tasks strongly depend on ...
