It has been suggested that phytosterol and phytostanol esters possess similar cholesterol-lowering properties, however, whether mechanisms responsible are identical not addressed. To address this question, cholesterol plasma levels, absorption, biosynthesis, turnover were measured in 15 hypercholesterolemic subjects consuming prepared diets each over 21 d using a crossover design. Diets contained either i) margarine (M), ii) with (MSE) (1.84 g/d), or iii) (MSA) g/d). Cholesterol absorption...

Although the dog is principal species used for in vivo studies of atrial arrhythmias, little known about currents governing canine repolarization. Cells were isolated from atria by exposure to collagenase tissue vitro (“chunk cells”) and arterial perfusion (“perfusion cells”). Whole cell voltage clamp revealed transient outward K+ current (Ito1), Ca(2+)-dependent Cl- (Ito2), delayed rectifier (IK). Ito1 recovered rapidly showed frequency dependence. Two components IK present as follows: a...

Purpose The purpose of this paper is to provide reference for researchers by reviewing the research advances and trend agricultural product price forecasting methods in recent years. Design/methodology/approach This reviews main their application prices, summarizes examples common methods, prospects future directions. Findings 1) It use hybrid models predict products prices research; 2) prediction model based on influencing factors should be further expanded 3) performance evaluated DS...

Abstract. SO2 and NOx are precursors to form sulfate, nitrate, ammonium particles in the air, which account for more than 50 % of PM2.5 mass eastern US (Bell et al., 2007) dominant components during many smog events (Dabek-Zlotorzynska 2011). H2SO4 HNO3, formed from oxidation NOx, respectively, main sources acid deposition through wet dry depositions. is also a precursor formation tropospheric O3, an important atmospheric oxidant essential other oxidants, such as OH H2O2. In past 26 years...

Abstract Weighted twin support vector machine (WTSVM) has been proved to be effective for classification problems. However, it is sensitive noises, especially data corrupted by outliers. In this paper, we propose an improved classifier termed as weighted with rescaled hinge loss (RHWTSVM). Similar WTSVM, uses the intra-class KNN technique extract structural information in same class. It inter-class reduce redundant constraints improve computational speed. Furthermore, introduce...

A size‐resolved model of below‐cloud scavenging is required in air quality and atmospheric dispersion modeling. Explicit calculation the snow coefficient requires determinations (1) cross section, (2) terminal velocity, (3) number size distribution particles; (4) spectral collision efficiency aerosol particles with particles. In this study, we present a for scavenging, based on current knowledge each element above. particular, new scheme proposed to specify whole range The specifies...

Abstract Objectives Food quality assessment is critical for indicating the shelf-life and ensuring food safety or value. Due to high environmental sensitivity, post-harvest of fresh fruit will undergo complex changes in supply chain, with various dynamic quality-related features. It difficult efficiently accurately extract comprehensive feature fruits from high-dimensional monitoring data heterogeneous characteristics (numerical categorical). Therefore, we proposed a method based on...

Purpose The paper aims to understand the cost-benefits, financial performance and relationships of key actors in table grape supply chain by using value analysis method. Design/methodology/approach This study presents result on three chains relationship among them analysis. was analyzed data collected from a field survey 5 regions China. these were interviewed. costs, benefits, operational analyzed. Findings results show that, despite receiving highest proportion total net profit making...

To examine the validity of deuterium (D) incorporation technique for measurement human cholesterol synthesis rates, D uptake from D2O into was compared to sterol balance in 13 subjects each under three controlled diet settings. Subjects (age 62 ± 3.6 yr, body weight 74 4.0 kg, BMI 27 1.4) consumed maintenance diets enriched either corn oil, beef tallow, or stick oil margarine over a 5-week period. During final week study period, were given 1.2 g/D2O per kg water. enrichment measured plasma...

Purpose – The paper aims to understand consumers' perception and cognition toward table grapes, which focuses on the most important attributes, consumption consequences personal values of grape relations among them. Design/methodology/approach study related with consumers based Means-end chain analysis. data were gathered both laddering interviews ( n =37) questionnaire survey returned by 843 individuals in 31 provinces China. firstly processed SPSS software descriptive statistics was...

Purpose Chinese consumers have increased their consumption of grape products in recent years due to recognition the nutritional value grapes. At same time, are paying more attention food safety because occasional occurrence scares. Based on a survey Zhejiang, China, this paper aims understand and provide information consumers' perceptions quality for products, purchasing behavior, willingness pay (WTP) products. Design/methodology/approach This presents results empirical research. The method...

Abstract BACKGROUND: Tilapia has been named as the ‘food fish of 21st century’ and become most important farmed fish. China is world leader in tilapia production export. Identifying information functional requirements critical developing an efficient traceability system because a fundamental prerequisite for exporting aquaculture products. RESULTS: This paper examines export‐oriented chains flow chains, identifies key actors, information‐capturing points. Unified Modeling Language (UML)...

Purpose The purpose of this paper is to develop a common remaining shelf life prediction model that generally applicable for postharvest table grape using an optimized radial basis function (RBF) neural network achieve more accurate than the current (SL) methods. Design/methodology/approach First, final indicators (storage temperature, relative humidity, sensory average score, peel hardness, soluble solids content, weight loss rate, rotting fragmentation rate and color difference) affecting...
