By a method of cultivation that proved successful with Bacterium pneumosintes, characteristic surface colonies of old saprophytic strains of Treponema pallidum and Treponema calligyrum have been obtained. The presence of two types of colony in the pallidum cultures requires explanation, but the fact of colony formation may point the way to new methods of isolation and identification and to the ...

the relationship between blood physiological attributes and carcass characteristics wasstudied in 40 randomly selected 8-month-old ram lambs of ghezel and mehraban (20 rams per breed)sheep. one day before slaughter, blood samples were obtained after a 24 hr fast. serum samples wereassayed for glucose, cholesterol, serum urea nitrogen (sun), total protein, albumin, triglycerides,creatinine, and ...

PURPOSE Hypotensive anesthesia with sodium nitroprusside (SNP) often is associated with reflex tachycardia. The purpose of this study was to investigate whether a small bolus of esmolol could counteract SNP-induced reflex tachycardia and sympathetic activation without affecting blood pressure. MATERIALS AND METHODS Using a time-series study design, 27 healthy young patients scheduled for mand...

OBJECTIVE We aimed to study the association among ABO blood group, von Willebrand factor, factor VIII plasma levels, and the risk of venous thrombosis (VT) in a cohort of 1774 relatives from 500 families with inherited thrombophilia. METHODS AND RESULTS One hundred sixty-one of the 1774 relatives had a VT. Different risk groups were formed: no, low-(factor V Leiden or F2G20210A heterozygous c...

The amplitude of low-frequency (LF) oscillations of heart rate (HR) usually reflects the magnitude of sympathetic activity, but during some conditions, e.g., physical exercise, high sympathetic activity results in a paradoxical decrease of LF oscillations of HR. We tested the hypothesis that this phenomenon may result from a feedback inhibition of sympathetic outflow caused by circulating norep...

The influence of environmental heat stress on the arterial baroreflex control of heart rate (HR) was studied in eight conscious, chronically instrumented baboons. Inflations of balloon occluders around the inferior vena cava (IVC) and thoracic descending aorta (DA) were used to produce acute, graded changes in mean arterial blood pressure (MABP) in 5 mm Hg intervals ranging from +/- 5 to +/- 25...

Objective(s) The purpose of the present study was to evaluate the effect of Ramadan fasting and weight-lifting training on plasma volume, glucose, and lipids profile of male weight-lifter. Materials and Methods Forty male weight-lifters were recruited and divided into 4 groups (n=10 each) and as the following groups: control (C), fasting (F), training (T) and fasting-training (F-T). The T an...

Background Although elevated blood pressure is associated with an increased risk of atrial fibrillation (AF), it is unclear if this association varies by individual characteristics. Furthermore, the associations between AF and a range of different vascular events are yet to be reliably quantified. Methods Using linked electronic health records, we examined the time to first diagnosis of AF an...

Sodium azide-crystal violet-agar and a modified blood-azide (MBA)-agar were used to isolate Erysipelothrix rhusiopathiae from swine tissues. There was no significant difference in the number of isolations. However, 78% of the isolants from modified blood-azide medium required only 24 hr of incubation, whereas all of the isolants obtained on sodium azide-crystal violet medium required 48 hr.

OBJECTIVE This study sought to investigate the progression and regression of diabetic retinopathy (DR) and the effects of population risk factors on the rates of transition across retinopathy stages. RESEARCH DESIGN AND METHODS The study cohort consisted of 44,871 observed DR events between the calendar years 1990 and 2011 for 4,758 diabetic patients who were diagnosed at 35 years of age or o...
