AIM To investigate the functional effects of abnormal esophagogastric (EGJ) measurements in asymptomatic healthy volunteers over eighty years of age. METHODS Data from 30 young controls (11 M, mean age 37 ± 11 years) and 15 aged subjects (9 M, 85 ± 4 years) were compared for novel metrics of EGJ-function: EGJ-contractile integral (EGJ-CI), "total" EGJ-CI and bolus flow time (BFT). Data were a...

c NORMAL SWALLOWING Sherrington originally studied swallowing in decerebrate cats. He described the effect of various agents—whiskey, oil, water—which, when dropped onto the area supplied by the superior laryngeal nerve, would elicit a “swallow”. This “swallow” did not involve any preparation of a bolus or any lingual propulsion, and was justifiably considered to be a reflex. I will use the ter...

DESIGN Double blind, placebo controlled, randomised trial, conducted from February 2008 to June 2010. SETTING Five maternity hospitals in the Republic of Ireland. PARTICIPANTS 2069 women booked for elective caesarean section at term with a singleton pregnancy. ...

(h) Controlled-release glass boluses (35 g) for use in sheep. The bolus contains by weight 13.4% copper. 0.5% cobalt and 0.3% selenium in a soluble glass matrix. (i) Sustained-release rumen bolus (80 g) for cattle. The bolus is composed of a compressed mixture of copper. cobalt. selenium. manganese. zinc. iodine and vitamins A. D and E. The round end of one bolus has been removed to show the 25...

Background: Nowadays, the most important aspect of hemodialysis is the technical method of anticoagulation of extracorporeal circuit. This quasi-experimental study was performed to compare three methods of heparinization in the extracorporeal circulation. Methods: Twenty-seven hemodialysis patients referring to Rafsanjan Hemodialysis Center with the weight range of 50-90 kg and normal Clotting ...

The present study examined the long-term efficacy of insulin pump therapy for type 1 diabetes patients when carried out using carbohydrate counting with bolus calculators for 1 year. A total of 22 type 1 diabetes patients who had just started continuous subcutaneous insulin infusion were examined and divided into two groups: one that was educated about carbohydrate counting using bolus calculat...

Abstract Background Oral corticosteroids remain as the first-line treatment for moderately active ulcerative colitis (UC). In controlled studies, they achieved clinical remission in 30-60% of patients at 30 days. severe systemic diseases, intravenous bolus administration methyl-prednisolone accelerates response and increases therapeutic efficacy corticosteroids. Aims To assess additive effect I...

Purpose. The aim of the present work was to test the feasibility of the time-resolved MR-angiography (TWIST-MRA) of cervical arteries using double bolus injection. Material and Methods. TWIST-MRA with a temporal resolution of 8.4 seconds for each frame and a spatial resolution with a voxel size of 0.61 × 0.58 × 0.8 mm(3) was performed in 24 patients. A biphasic bolus injection protocol was used...
