AIM: To assess the effects of soy protein, isoflavone, and saponin on liver and blood lipid in rats that consumed high-cholesterol diets.METHODS: High-cholesterol diets (1%) with or without soy material were fed to 6-wk-old male Sprague-Dawley rats for 8 wk. Blood lipids, liver lipids, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) levels were measured. The in vitro bile acid-binding ability of soy materials was analyzed.RESULTS: The results of in vitro studies showed that soy protein isolate had a significantly higher bile acid-binding ability (8.4±0.8%) than soy saponin (3.1±0.7%) and isoflavone (1.3±0.4%, P<0.05). On the other hand, at the end of the experimental period, rats that consumed soy protein diets had lower GOT and GPT levels than rats that consumed casein under high-cholesterol diets.Rats that consumed soy protein also had lower total cholesterol (TC) levels in the liver than those that consumed casein under high-cholesterol diets. Rats that consumed the soy protein diet containing both saponin and isoflavone had lower hepatic TC level than those that consumed the soy protein diet without isoflavone alone.The effect of different types of proteins on triglyceride was not significant.CONCLUSION: Consumption of soy provided benefits to control lipid levels under high-cholesterol dieting conditions in this rat model of hypercholesterolemia. The major component that reduced hepatic TC was not saponin, but possibly isoflavone. 展开更多

AIM:To evaluate the effects of ursodeoxycholic acid (UDCA) and/or low-calorie diet (LCD) on a rat model of nonalcoholic steatohepatitis (NASH). METHODS: Fifty-five Sprague-Dawley rats were divided into five groups. The control group (n = 9) was fed with standard rat diet for 12 wk, NASH group (n = 10) was fed with high-fat diet consisted of normal diet, 10% lard oil and 2% cholesterol for 12 wk, UDCA group (n = 10) was fed with high-fat diet supplemented with UDCA at a dose of 25 mg/(kg · d) in drinking water for 12 wk, LCD group (n = 10) was fed with high-fat diet for 10 wk and then LCD for 2 wk, and UDCA+LCD group (n = 15) was fed with high-fat diet for 10 wk, followed by LCD+UDCA for 2 wk. At the end of the experiment, body weight, serum biochemical index, and hepatopathologic changes were examined. RESULTS: Compared with the control group, rats in the NASH group had significantly increased body weight, liver weight, and serum lipid and aminotransferase levels. All rats in the NASH group developed steatohepatitis, as determined by their liver histology. Compared with the NASH group, there were no significant changes in body weight, liver weight, blood biochemical index, the degree of hepatic steatosis, and histological activity index (HAI) score in the UDCA group; however, body and liver weights were significantly decreased, and the degree of steatosis was markedly improved in rats of both the LCD group and the UDCA+LCD group, but significant improvement with regard to serum lipid variables and hepatic inflammatory changes were seen only in rats of the UDCA+LCD group, and not in the LCD group. CONCLUSION: LCD might play a role in the treatment of obesity and hepatic steatosis in rats, but it exerts no significant effect on both serum lipid disorders and hepatic inflammatory changes. UDCA may enhance the therapeutic effects of LCD on steatohepatitis accompanied by obesity and hyperlipidemia. However, UDCA alone is not effective in the prevention of steatohepatitis induced by high-fat diet. 展开更多

AIM: To characterize the influence of diet-induced changes in body fat on colitis severity in SlVlAD3-/- mice.METHODS: SMAD3-/- mice (6-8 wk of age) were ran- domly assigned to receive a calorie restricted (30% of control; CR), control (CON), or high fat (HF) diet for 20 wk and were gavaged with sterile broth or with Helicobacter hepaticus (H. hepaticus) to induce colitis. Four weeks after infection, mice were sacrificed and the cecum and colons were processed for histological evaluation.RESULTS: Dietary treatment significantly influenced body composition prior to infection (P 〈 0.05), with CR mice having less (14%±2%) and HF-fed mice more body fat (32% ± 7%) compared to controls (22%±4%). Differences in body composition were associated with alterations in plasma levels of leptin (HF 〉 CON 〉 CR) and adiponectin (CON 〉 HF 〉/ CR) (P 〈 0.05). There were no significant differences in colitis scores between CON and HF-fed mice 4 wk post-infection. Consistent with this, differences in proliferation and in- flammation markers (COX-2, iNOS), and infiltrating cell types (CD3^+ T lymphocytes, macrophages) were not observed. Unexpectedly, only 40% of CR mice survived infection with H. hepaticus, with mortality observed as early as I wk following induction of colitis.CONCLUSION: Increased adiposity does not influence colitis severity in SMAD3-/- mice. Importantly, caloric restriction negatively impacts survival following pathogen challenge, potentially due to an impaired immune response. 展开更多

The experiment was conducted using a total of 1392 one-day-old, Cobb commercial male broilers to investigate the effects of a commercial probiotic addition in diet on growth, the development of the small intestine and microbial populations of broilers. Broilers were randomly allotted by BW to 1 of 6 replicate cages (29 chicks per cage) for each of 8 treatments in a randomized block design involving one factorial arrangement of treatments. Dietary treatments included the basal diet (including corn, soybean, rapeseed, cottonseed meal) added with 100 mg/kg antibiotic, 0%, 0.05%, 0.1%, 0.15%, 0.2%, 0.25% or 0.3%. The experiment last 42 d and divided into the starter period (1-21 d) and the finisher period (22-42 d). The results showed that there were significant differences in broiler body weight (BW) (P〈0.001), average daily feed intake (ADFI) (P=0.033), relative length of the duodenum (P〈0.001), jejunum (P=0.008), ileum (P〈0.001) and the populations of lactobacillus (P〈0.001) and coliform (P〈0.001) in the rectum between the probiotics treatments and the control treatment only in the starter period of the trails. No significant differences were observed in intestinal morphology parameters in two periods of the experiment. Our results indicated that the probiotic was able to improve the performance of broiler chickens, and it was better in the starter period to be used than in the finisher period. 展开更多

The effectiveness of a magnetic ion exchange resin (MIEX) for the treatment of Hongze Lake water in China was evaluated, The kinetics of natural organic matter (NOM) removal at various MIEX doses and contact time, multiple-loading experiments, impacts of MIEX prior to coagulation on coagulant demands and the effectiveness of combination of MIEX, pre-chlorination and coagulation were investigated. Kinetic experimental results show that more than 80% UV254 and 67% dissolved organic carbon (DOC) from raw water can be removed by the use of MIEX alone. 94% sulfate, 69% nitrate and 98% bromide removals are obtained after the first use of MIEX in multiple-loading experiments. It is suggested that MIEX can be loaded up to 1 250 bed volume (BV, volume ratio of tested water to resin) or more without saturation when regarding organics removal as a target. MIEX can remove organics to a greater extend than coagulation and lower the coagulant demand when combining with coagulation. Chlorination experimental results show that MIEX can remove 57% chlorine demand and 77% trihalomethane formation potential (THMFP) for raw water. Pre-chlorination followed by MIEX and coagulation can give additional organic and THMFP removals. The results suggest that MIEX provides a new method to solve thc problem algae reproduction. 展开更多

The objective of this study was to evaluate the effect of high digestible essential amino acids (DEAA) on weight gains and carcass compositions of laying hens. Three hundred and sixty lsa Brown hens in five replications per treatment (12 birds/replicate) were used. Six experimental diets which contained of treatment 1 (negative control) as the conventional layer diet are recommended by NRC (1994) while another dietary treatments; treatments 2 (positive control), 3, 4, 5 and 6 were formulated to meet 100%, 110%, 120%, 130% and 140% of Standard Ileal Digestible Lysine Levels (SIDLL) without crude protein minimum, while methionine (Met), threonine (Thre) and tryptophan (Tryp) as related by Ideal Protein Concept (IPC) which suggested by NRC (1994) and INRA (2004). However, metabolizable energy (ME), calcium and available phosphorus (Avai P) levels of all experimental diets were meet requirement as recommended by NRC (1994). The experiment was assigned in CRD and laying hens fed dietary treatments from 28 to 44 weeks of age and cage was the experimental unit (3 hens/cage). The result shown that percentages of thigh (TP), feet (FP), drumstick (DP), heart (HP), liver (LP) and gizzard (GP) were not affected by dietary treatment. However, weight gains (WG) and percentage of dressed weight (DWP), eviscerate weight (EWP) and breast (BP) were increased (P 〈 0.05) and abdominal fat was reduced (P 〈 0.05) when birds fad diets containing 130% of SIDLL as compared with control group and another dietary treatments, when increasing the DEAA levels upper to 130% of SIDLL. The result indicated that diets formulated without crude protein minimum and increased DEAA resulted in increasing the efficiency of converting metabolizable energy (ME) to net energy (NE) for increasing weight gain and improved meat products while fat deposition in carcass composition was reduced. 展开更多

I) and N balance (Exp. 2) in growing pig. In Exp. 1, 36 castrated pigs [21.35 -4- 0.55 kg of body weight (BW)] were allotted to six treatments with six replicates per treatment. Pigs were fed two levels of Lys (low and high) and three levels of NE (low, med, or high) in a 2×3 factorial arrangement. The experiment lasted for 35 d. There were no effects of dietary Lys and NE on pig performance (P〉0.05, but a Lys×NE interaction in ADG was observed (P〈0.05). In Exp. 2, 24 pigs were used to determine the effects of diet in Exp. 1 on pig N balance. Neither Lys nor NE level affected N retention (g/d) (P〉0.0). Lys×NE interaction in N retention (g/d) (P〈0.01) and in N apparent biological value (ABV) (P〈0.05) was observed. Pigs fed the low Lys diet had lower serum urea nitrogen (SUN) concentrations compared with the high Lys treatment (P〈0.01). Pigs fed the med-NE diet had lower SUN concentrations compared with the pigs fed the low-NE diet (P〈0.1). These results suggest that pigs from 21 kg to 50 kg BW fed diets containing 0.83% standardized ileal digestible Lysine and 2351 Kcal of NE/kg had maximum ADG and N retention. 展开更多

The paper analyzes the dynamic behaviour of an industrial system devoted to the automated hydraulic packaging of beverages. More in detail, a lumped and distributed numerical approach is used to model both the filling system and the multi-actuators hydraulic circuit needed to shape and separate the packages. The model reliability and accuracy are addressed by means of a numerical vs. experimental comparison of the main hydraulic and mechanical quantities for an actual production rate. Afterwards, the system architecture is redesigned in order to obtain higher production rates, and the effects of the hydraulic behaviour variation on the hydraulic efficiency are highlighted. Finally, a sensitivity analysis with respect to the main design parameters is carried out, in order to determine the circuit layout that maximizes the system efficiency in the whole production-rate range. 展开更多

Currently,the topic of food waste and its environmental impacts is attracting increasing attention among academic researchers.Based on an investigation of restaurants in Beijing,this study analyzes the quantities,structures,characteristics and costs of the agricultural resources related to food waste in the catering industry in Beijing.The results show that:(1)The average food waste per capita per meal is about 75.02 g(raw)for food away from home among Beijing urban residents,which means that about 10.52%of the food is wasted.(2)According to the quantitative ranking of different categories of food waste,vegetable is the most wasted,followed by meat,aquatic products,and grains.The foods in the other categories are wasted much less.(3)Food waste is affected by the restaurant type,as well as the number,gender,age,education level,and consumption motivation of the consumers.(4)Based on the estimated food waste per capita,about 417.92 thousand tons of food is wasted annually at the consumption stage in the catering industry in Beijing.This food waste amount is equivalent to approximately 765.53 tons of cereals which are wasted,and this represents 79.66%of cereals production and 13.15%of cereals consumption in Beijing.Estimated by the required land use,this amount of food waste means that the total production of approximately 166.12 thousand ha of arable land is being wasted in Beijing. 展开更多

The degradation of Microcystin-LR (MC-LR) in water by hydrogen peroxide assisted ultraviolet (UV/H2O2) process was investigated in this paper. The UV/H2O2 process appeared to be effective in removal of the MC-LR. MC-LR decomposition was primarily ascribed to production of strong and nonselective oxidant-hydroxyl radicals within the system. The intensity of UV radiation, initial concentration of MC-LR, MC-LR purity, dosages of H2O2, the initial solution pH, and anions present in water, to some extent, influenced the degradation rate of MC-LR. A modified pseudo-first-order kinetic model was developed to predict the removal efficiency under different experimental conditions. 展开更多
