Endoscopic tissue shielding with polyglycolic acid (PGA) sheets (Neoveil; Gunze Co., Kyoto, Japan) and fibrin glue (Beriplast P CombiSet; CSL Behring Pharma, Tokyo, Japan) is a promising method for preventing postoperative complications [1–3]. However, this technique is thought to be inefficient for covering large mucosal defects because it takes time to deliver many small PGA sheets. According...

Within the wide spectrum of axonal diameters occurring in mammalian nerve fibers, each class of neurons has a relatively restricted range of axonal calibers. The control of caliber has functional significance because diameter is the principal determinant of conduction velocity in myelinated nerve fibers. Previous observations support the hypothesis that neurofilaments (NF) are major intrinsic d...

• A fundamental characteristic of blood vessels is the ability to change in caliber in response to neural and chemical stimuli. The effects of such changes on the architecture of the vessel wall cannot be appreciated in studies on physical models, such as soap bubbles and balloons, which have negligible wall thickness and uniform composition. The familiar Laplace relationship (T = PR) states th...

Taking a large-caliber gun as the research object, projectile and coupling finite element numerical simulation model during extrusion process is established according to technology. The dynamic of carried out by using ABAQUS/EXPLAICT solver, stress variation law belt groove barrel obtained. In post-processing module software, data displacement, velocity acceleration at center mass in are extrac...

It has been reported that the distal interosseous membrane (DIOM) of the forearm constrains the dorsal dislocation of the distal radius. A residual ulnar translation deformity of the radial shaft in distal radius fractures has the potential to cause distal radioulnar joint (DRUJ) instability when triangular fibrocartilage complex (TFCC) injury is also present, because it may result in detension...

Statistical analysis of measurement of aortic length made on 250 angiocardiograms indicates that arteriosclerosis, hypertension and syphilitic aortitis produce elongation of the aorta. Aortic length varies widely among normal individuals but is roughly ten times the caliber of the ascending aorta. Syphilitic aortitis produces disproportionate elongation of the ascending portion of the aorta as ...

We aimed to determine the association between blood pressure (BP) and retinal vascular caliber changes that were free from confounders and reverse causation by using Mendelian randomisation. A total of 6528 participants from a multi-ethnic cohort (Chinese, Malays, and Indians) in Singapore were included in this study. Retinal arteriolar and venular caliber was measured by a semi-automated compu...

Although cigarette smoking is a major cardiovascular risk factor, its microcirculatory effects are not well understood. The authors investigated cross-sectional and longitudinal relations between smoking and retinal microvascular caliber in an older Australian population. Retinal vessel calibers were measured from digitized retinal photographs at baseline (1992-1994; n = 3,006) and at 5-year fo...

The resurgence in popularity of subsonic .30 caliber bullets in 300 Whisper and 300 Blackout has led to the development of bullets that will expand at subsonic velocities. The availability of these bullets has led to questions about the applicability of this caliber for wildlife damage management. We conducted a preliminary investigation to determine the potential of subsonic .30 caliber bullet...

OBJECTIVE To compare the free blood flow, caliber, and length of the left internal thoracic artery (LITA), dissected in the pedicled (P) and skeletonized (S) manners, during surgery before and after topical vasodilator (TV) application. METHODS A randomized, blind, clinical trial was carried out with 50 patients undergoing elective myocardial revascularization to assess the use of the LITA in...
