Background and Objectives There is no clear standard for the difference in thresholds of auditory brainstem response (ABR) pure tone audiometry (PTA) when using ABR to evaluate reliability PTA. Therefore, we assessed PTA each frequency. Consequently, present here actual values between two tests that can be used as a reference clinic.Subjects Method We retrospectively results 129 ears. Ears whic...

We report three cases of iliac artery rupture during percutaneous transluminal angioplasty (PTA). In all three cases, bleeding was temporarily controlled by inflating an angioplasty balloon at the site of bleeding. Two patients underwent subsequent surgical revascularization, and one underwent endovascular stent grafting but ultimately required a surgical bypass. Arterial rupture is a rare but ...

Integrational plasmid technology has been used to disrupt metabolic pathways leading to acetate and butyrate formation in Clostridium acetobutylicum ATCC 824. Non-replicative plasmid constructs, containing either clostridial phosphotransacetylase (pta) or butyrate kinase (buk) gene fragments, were integrated into homologous regions on the chromosome. Integration was assumed to occur by a Campbe...

A retrospective analysis of the Vascular Quality Initiative between 2011 and 2020. Alternate-percutaneous balloon angioplasty (PTA) interventions, which included atherectomy, drug-coated balloons, bare metal stents, coronary drug-eluting to treat chronic limb-threatening ischemia (CLTI) significantly increased over study period from 18% 33%. Advanced age, increasing TransAtlantic Inter-Society ...

The purpose of this study was to enhance the sensitivity of the Western blot (WB) test for use as an alternative and confirmatory method for the diagnosis of scrapie and chronic wasting disease (CWD) in Canada by comparing 2 sample preparation procedures: an abnormal prion protein (PrPSc) concentration procedure using sodium phosphotungstic acid (PTA) precipitation and a procedure using crude s...

OBJECTIVE Conventional percutaneous transluminal angioplasty (PTA) for long lesions in the below-the-knee (BTK) arteries in patients presenting with critical limb ischemia (CLI) has high restenosis rates at 1 year. Our goal is to evaluate whether paclitaxel drug-eluting balloons (DEB) have higher 1 year primary patency rates compared to conventional PTA. METHODS This is a single-center, prosp...

The phosphotungstate anion (PTA) is widely used to facilitate the precipitation of disease-causing prion protein (PrP(Sc)) from infected tissue for applications in structural studies and diagnostic approaches. However, the mechanism of this precipitation is not understood. In order to elucidate the nature of the PTA interaction with PrP(Sc) under physiological conditions, solutions of PTA were ...

BACKGROUND/AIM Idiopathic sudden sensorineural hearing loss (ISSHL) is one of the most controversial issues in otology. The aim of this study was to determine whether a delay in treatment has any influence on hearing recovery in ISSHL. METHOD This study was designed as a retrospective evaluation of an electronic patient data base of the University Hospital Zürich from January 1995 to August 2...

PURPOSE We review our initial experience with direct percutaneous transluminal angioplasty (PTA) as a reperfusion treatment for acute occlusion of the middle cerebral artery. METHODS Ten patients in whom successful thrombolysis might not be expected because of the risk of hemorrhagic complications or reocclusion were treated with direct PTA. When early ischemic findings were present on the in...

Abstract Pulsar timing array (PTA) experiments are expected to detect nano-Hertz gravitational waves (GWs) emitted from individual inspiralling supermassive binary black holes (SMBBHs). The GW signals a small fraction of these SMBBHs may be diffractively lensed by intervening galaxies. In this paper, we investigate the diffractive lensing effects on continuous and estimate detectable number suc...
