Gum arabic (GA) is a water-soluble polysaccharide (molecular weight approximately 850 000) containing rhamnose, arabinose, glucuronic acid and galactose. The metabolism of GA has been studied in the rat. Adult male Wistar rats were given GA incorporated into either an Oxoid breeders (OB) diet or an elemental (Elem) diet. Intestinal contents were examined for precipitable GA using acidified etha...
In recent years, intra-abdominal visceral fat leads to obesity-related complications. A simple indicator that reflects the mass of visceral fat is also needed to enable practical screening of patients. The present study was designed to establish new body mass index (BMI) criteria of central obesity for male Japanese. The subjects were 516 men aged from 19 to 80 years old who were examined at th...
Wether sheep were fitted with rumen fistulas and polyethylene tubes to the abomasum and were given all nutrients by intragastric infusion. In Expt 1 volatile fatty acids (VFA) were given at 340, 450 and 630 kJ gross energy (GE)/kg metabolic weight (W0-75) and protein at 0, 150, 300, 600, 900 and 1500 mg nitrogen/kg W0-75. In Expt 2 VFA were infused at 450 kJ GE/kg W0-75 and protein at 0 and 300...
The predominant risk factor of metabolic syndrome is intra-abdominal fat accumulation, which is determined by waist circumference, waist-hip ratio measurements and visceral fat area (VFA); the latter can be accurately measured by performing computed tomography (CT). In addition to environmental factors, genetic factors play an important role in obesity and fat distribution. New genetic loci ass...
PURPOSE To evaluate the relationships between insulin sensitivity (IS), body fat accumulation, and aerobic capacity in middle- to older-aged Japanese participants with visceral adiposity. PARTICIPANTS AND METHODS Aerobic capacity was measured during an incremental ramp exercise test. Computed tomography was used to measure visceral (VFA) and subcutaneous (SFA) fat area, the fat in liver-to-sp...
OBJECTIVE To investigate the association between visceral fat area (VFA) and metabolic syndrome (Mets) among normal weight Japanese. DESIGN A cross-sectional study. SETTING The health check-up centre of the Takeda Hospital group in Kyoto, Japan. METHODS This study involved 1674 men and 1448 women aged 30-74 years who underwent medical check-ups in 2012 in the health check-up centre. They ...
OBJECTIVE The visceral fat area (VFA) was measured, and the relationships between the VFA and the body mass index (BMI), waist circumference, blood pressure, and indices of lipid and sugar metabolism were evaluated. METHODS The subjects included 607 consecutive patients who underwent VFA examinations using computed tomography (CT) scans. In addition to the routine examination parameters, the ...
VFA is used for most of the analog circuit design but in many high frequency applications like integrator and differentiator it’s finite slew rate, finite gain bandwidth product limitation degrades its performance. Thus, the introduction of CFA possessing a number of advantages including high slew rate due to its current feedback architecture, closed loop bandwidth that is independent of closed...
A well-defined fractionation approach for sludge flocs was applied to a better understanding of the underlying mechanism of improving the production of volatile fatty acids (VFA) in the hydrolysis and acidification processes at pH 10.0. Specifically, sludge flocs were fractionated through centrifugation and ultrasound into four fractions: (1) slime, (2) loosely bound extracellular polymeric sub...
Objective The aim of this study was to examine the associations between the visceral fat area (VFA) and the subcutaneous fat area (SFA) as estimated by the dual impedance method with a body composition monitor (BCM) and the diagnostic components of metabolic syndrome in a middle-aged Japanese population. Methods The subjects included 303 men (average age 51.3±9.0 years old) and 345 women (avera...
