BACKGROUND AND PURPOSE Invasive cerebral DSA has largely been replaced by CTA, which is noninvasive but has a compromised arterial view due to superimposed bone and veins. The purpose of this study was to evaluate whether arterial visualization in CTPa is superior to standard CTA, which would eliminate the need for an additional CTA scan to assess arterial diseases and therefore reduce radiatio...

OBJECTIVE Initial reports have shown percutaneous sonographically guided needle tenotomy without corticosteroid injection to be effective for the treatment of tennis elbow. The purpose of this study was to determine the effectiveness of this procedure with various tendons throughout the body. METHODS Fourteen tendons in 13 patients were identified as having a greater than 6-month history of c...

ABSTRACT This is a report of a study on the long term results of PHILOS plating and percutaneous K-wire fixation in a prospective series of proximal humerus fractures in elderly patients. We reviewed a total of 60 patients with proximal humerus fractures in 30 patients (Group 1), who were treated by open reduction and internal fixation with Proximal Humeral Internal Locking System (PHILOS) plat...

OBJECTIVE Sometimes a vertebral artery (VA) enters the spinal canal via the C1-2 intervertebral space, a variation regarded as a C2 segmental-type VA. This paper describes the anatomy of the C2 segmental-type VA and reviews its clinical importance. METHODS Between March 2014 and November 2015, 3386 patients underwent computed tomographic angiography. I identified C2 segmental-type VAs, associ...

BACKGROUND Radiofrequency catheter ablation (RFCA) of idiopathic ventricular arrhythmias (VAs) originating from the basal portion of the left ventricular (LV) summit, which is divided from the apical LV (A-LV) summit by the great cardiac vein (GCV), is challenging. This study investigated the efficacy of RFCA and electrocardiographic and electrophysiological characteristics of these VAs. METH...

The goal of this study was to test for expression of HCO3 (-) exchangers SLC26A3 and SLC26A6 in primary cultures of porcine vas deferens epithelial cells (1°PVD) and native porcine vas deferens. Quantitative RT-PCR revealed that mRNA coding for SLC26A6 was six times more abundant than mRNA coding for SLC26A3 in 1°PVD cells. Western blot analyses combined with surface biotinylation of 1°PVD demo...

Physiol. 275 (Cell Physiol. 44): C1134–C1142, 1998.— The lumen of the epididymis is the site where spermatozoa undergo their final maturation and acquire the capacity to become motile. An acidic luminal fluid is required ...

BACKGROUND chronic proximal hamstring tendinopathies is a disabling activity related condition. Currently, there is no well-accepted or extensively documented non-operative treatment option that provides consistently successful results. PURPOSE to evaluate the efficacy of ultrasound guided platelet-rich plasma injections in treating chronic proximal hamstring tendinopathies. METHODS a total...

To gain insight into mucin 2 (Muc2) synthesis and secretion during dextran sulfate sodium (DSS)-induced colitis, rats were treated with DSS for 7 days. Colonic segments were excised on days 0 (control), 2 (onset of disease), 7 (active disease), and 14 (regenerative phase) for histological evaluation. Explants were metabolically labeled with (35)S-labeled amino acids or [(35)S]sulfate followed b...
