OBJECTIVE To describe the genotypic variability of group A rotavirus (RVA) found in immunosuppressed and non-immunosuppressed pediatric patients treated at the Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR), Curitiba, Paraná. METHODS A cross-sectional study was conducted with 1,140 stool samples collected from April, 2001 to December, 2008 in outpatients and hospitalized pat...

Rotavirus A (RVA) is recognized as a major etiology responsible for the development of acute gastroenteritis in children worldwide. The purpose present study was to perform molecular characterization RVA. total 323 stool specimens collected from hospitalized with Chiang Rai, Thailand, 2016-2018 were identified G- and P-genotypes through RT-PCR analysis. RVA more prevalent 2017-2018 (37.8%) than...

Введение. При создании совершенных технологических процессов, позволяющих получить готовый продукт высокого качества, необходимо практически в каждом конкретном случае изучать целый комплекс физико-механических свойств. Эти свойства характеризуют поведение пищевых масс под действием механических нагрузок со стороны рабочих органов машин. Большое значение пищевой промышленности имеет объективная...

Using intracardiac recording techniques, His bundle (H) and right ventricular apical (RVA) electrograms were recorded in 16 patients with a postoperative electrocardiographic pattern of right bundle branch block (RBBB). Their ages ranged from 5 to 12 years (mean 6.9 years) at surgery and the follow-up period was 1 to 7 years (mean 2.7 years). All were asymptomatic and in sinus rhythm at the tim...

Case report An 18-year-old male patient experienced frequent episodes of palpitations for 6 months. He was referred to our hospital for catheter ablation. This patient had no prior history of structural cardiovascular disease. His chest radiograph and transthoracic echocardiogram showed no abnormalities. The electrocardiogram (ECG) showed Wolff–Parkinson–White syndrome at baseline (Figure 1A) a...

Case report A 74-year-old man with symptomatic idiopathic VT that was refractory to multiple antiarrhythmic agents was referred to our hospital for electrophysiologic study. On admission, a 12lead ECG showed atrial fibrillation. Transthoracic echocardiography revealed normal left ventricular systolic function with a dilated left atrium. The His–ventricular interval at baseline was 45 ms. A sust...

The aim of the current study was to explore a novel method for measuring hydration and dissolution kinetics of the pulverized konjac flour (PK flour) from Amorphophallus albus using RVA-3D+ Rapid Visco Analyzer (RVA; Newport Scientific Pty Ltd., Australia). The results showed that RVA was a reliable fast technique for determining the hydration curve of PK flour. The test conditions determining ...

BACKGROUND Abnormal activation of the ventricles via right ventricular apical pacing deteriorates cardiac function, which may explain the increased mortality of patients with congestive heart failure receiving permanent pacemakers. We hypothesized that pacing at alternative sites may cause less detrimental effects on the cardiac function. METHODS Five symptomatic patients with either advanced...

The mechanism of action of diphenylhydantoin (DPH) on re-entrant ventricular arrhythmias (RVA) was studied in dogs 3-7 days following ligation of the anterior descending coronary artery utilizing direct recordings of the re-entrant pathway (RP) from the epicardial surface of the infarction zone (IZ). DPH in a therapeutic dose consistently prolonged refractoriness of potentially RP in the IZ. Th...

Starches from two ecotypes of achira roots (Canna edulis Ker-Gawler) were characterized and compared to commercial potato and corn starches. This included scanning electron microscopy (SEM) of starch granules and amylose content determination of starch. Starch solutions or gels were tested by rotational viscometry, Rapid Visco Analyzer (RVA), and texture analysis. Some starch samples were subje...
