A 35-year-old woman with chronic anterior cervicalgia was referred to our institution for an ultrasound of the neck. The B-mode ultrasound (Siemens S 2000, linear phased array probe 9 to 13 MHz) revealed a 1.6-mm hyperechoic circumferential wall thickening of the right common carotid artery, involving the whole artery, without evidence of stenosis (Figure 1). The other supraaortic arteries appe...

BACKGROUND High-resolution contrast-enhanced imaging of the murine atherosclerotic vessel wall is difficult due to unpredictable flow artifacts, motion of the thin artery wall and problems with flow suppression in the presence of a circulating contrast agent. METHODS AND RESULTS We applied a 2D-FLASH retrospective-gated CINE MRI method at 9.4T to characterize atherosclerotic plaques and vesse...

introduction bladder diverticulum is a result of bladder mucosa and submucosa herniation through the muscularis propria of bladder wall. bladder diverticula are mostly seen in the elderly men in association with benign prostatic hyperplasia (bph). case presentation a 74-year-old man presented with complaints of vague epigastric discomfort, dyspepsia, and mild lower urinary tract symptoms. an ul...

in the present work, the effects of changing punch and the die radius on several process parameters involved in deep drawing of aisi 304 steel have been studied. deep drawing process of a cylindrical cup was simulated and analysed by numerical modeling. the results were compared with those of obtained from a serie of experimental cupping tests. the comparison shows that: maximum drawing force d...

introduction: the horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (psaa) and the infraorbital artery. this anatomic structure is known as the ‘alveolar antral artery’.   materials and methods: we performed a literature review. the anatomic location of the alveolar antral artery in the latera...

Bacterial lysins are potent antibacterial enzymes with potential applications in the treatment of bacterial infections. Some lysins lose activity in the growth media of target bacteria, and the underlying mechanism remains unclear. Here we use CD11, an autolysin of Clostridium difficile, as a model lysin to demonstrate that the inability of this enzyme to kill C. difficile in growth medium is n...

ABSTRACT The flow of air past a smooth surface-mounted hemisphere is investigated numerically using six common RANS turbulence models and seeking steady solutions. Where possible, the are applied standard wall functions, resolving viscous sublayer, enhanced treatment option in ANSYS Fluent. Results simulations compared against measurements taken wind tunnel experiment. comparison shows that bou...

We study the quark number susceptibility, an indicator of QCD phase transition, in the hard wall and soft wall models of hQCD. We find that the susceptibilities in both models are the same, jumping up at the deconfinement phase transition temperature. We also find that the diffusion constant in the soft wall model is enhanced compared to the one in the hard wall model.
