The present study was performed to investigate the possible effects of wheat germ supplementation on lipid metabolism in humans. Ten free-living adult subjects participated in the study. None was obese or diabetic. They all presented an, hypercholesterolemia (from 6.58 to 9.50 mM), associated in 6 over 10 cases to an hypertriglyceridemia (from 1.70 to 5.00 mM). The subjects were studied in three consecutive periods, during which they first were on their usual diet (first week), they then ingested a daily supplement of 30 g wheat germ (4 weeks) and then they returned to their usual basal diet (4 weeks follow-up). Dietary records were obtained for 7 and 3 consecutive days before and during wheat germ supplementation, respectively. Fasting blood samples were taken at the end of each period. After 4 weeks of wheat, germ intake, glycemia did not change while total plasma cholesterol significantly decreased (paired Student'st test,p0.05) from 7.80 to 7.15 mM. LDL and HDL cholesterol values did not show marked changes, but VLDL cholesterol significantly dropped by 40.6%. Thus, the plasma/HDL total cholesterol ratio was significantly lower. Apoprotein B and A1 decreased. In the hypertriglyceridemic subjects, this was accompanied by a significant reduction of plasma triglycerides (1.64 vs. 2.68 mM) and a marked drop of VLDL triglycerides (–51%). Taken as a whole, the present results obtained in humans are very close to those previously obtained in the rat [40] and point out that wheat germ may play a beneficial role in the dietary management of hyperlipidemia.Part of the data communicated in this paper was presented at the Fibre 90 Conference, 17–20 April 1990, Norwich, UK.  相似文献

Agronomic performance and water-use efficiency of F3 soybean populations grown under contrasting base saturation     

Isabela Ramsdorf Gomes Patinni  Cristiane Alves de Andrade  Cid Naudi Silva Campos  Larissa Pereira Ribeiro Teodoro  Sinomar Moreira Andrade  Cassiano Garcia Roque  Carlos Antônio da Silva Junior  Paulo Eduardo Teodoro 《Journal of Agronomy and Crop Science》2020,206(6):806-814

Most of the Brazilian soils, especially in Cerrado biome, have high acidity and toxic aluminium, making the application of limestone an indispensable technique to obtain high yield in soybean crop. The hypothesis of this study was that contrasting base saturation provides changes in water-use efficiency (WUE) and agronomic traits of soybean populations. Thus, we evaluated the WUE and agronomic performance of F₃ soybean populations under different base saturation levels. Each experiment was conducted in a randomized complete blocks design with three replicates and 10 F₃ populations (P1, P2, P3, P4, P5, P6, P7, P8, P9 and P10) for two crop seasons. Segregating populations were obtained by bulk method. In the first experiment, F₃ populations were evaluated without correction of base saturation (V = 30%), while in the second experiment, limestone was applied three months before sowing to increase base saturation to 60%. The traits evaluated were as follows: calcium, magnesium and potassium contents, water-use efficiency (WUE), plant height, first pod height, main stem diameter and grain yield. Our findings indicate that WUE and agronomic performance of F₃ soybean populations depends on the saturation condition. We identified the P4 and P9 populations as the most promising for use in breeding programmes aiming at higher tolerance to abiotic stress caused by low base saturation in soil.  相似文献   

ACCURACY AND PRECISION OF DUAL-ENERGY X-RAY ABSORPTIOMETRY FOR EX VIVO DETERMINATION OF MINERAL CONTENT IN TURKEY POULT BONES

The right humerus was removed from 30 20-week-old male turkey poults for humerus strength analysis using dual-energy x-ray absorptiometry and humerus-breaking strength. Specimens were cleaned and dried before scanning. To determine the most precise and accurate protocol of bone densitometry analysis for avian long bones, we scanned each specimen using five different techniques, all aimed to simulate soft-tissue thickness. Correlation coefficients and linear regression equations between 1) bone mineral content and humerus ash, and 2) bone mineral density and humerus-breaking strength were estimated with each technique and compared. The coefficient of variation values for precision ranged from 0.40% to 1.69% for bone mineral content and from 0% to 4.19% for bone mineral density. The accuracy was determined by comparing the bone mineral content of each humerus with the corresponding ash weight; the correlation coefficients between the two parameters were highly significant (range 0.949-0.963; P < or = 0.01). Significant correlations were also observed between humerus-breaking strength and bone density measurements (range 0.762-0.785; P < or = 0.01). Linear regression coefficients relating both parameters considered were also highly significant. We concluded that dual-energy x-ray absorptiometry is an accurate and precise method with which to determine ex vivo bone mineral content and strength in turkey bones. Further investigations are requested for field applications of this method to study factors affecting bone physiology and strength.  相似文献   

Fruit Branding: Exploring Factors Affecting Adoption of the New Pear Cultivar ‘Angelys’ in Italian Large Retail     

Daniele Asioli  Maurizio Canavari  Luca Malaguti  Chiara Mignani 《International Journal of Fruit Science》2016,16(3):284-300

‘Angelys’ is a new brand of pear cultivar, produced and marketed under the trademark license model called “Club variety.” The main aim of this article was to evaluate factors triggering a potential interest in Italian large-scale retail regarding the marketing of ‘Angelys’ and how large-scale retailers would exploit it to enhance their market potential. An explorative analysis approach was applied via in-depth, semi-structured qualitative interviews with major Italian large-scale retail fruit purchase managers. The results show that although sensory properties, handling features, and Italian origin are highly appreciated by professional customers, the need to sell at a premium price might limit the interest of retailers for this new variety. Finally, implications and recommendations for academics and operators are discussed.  相似文献   

Dynamics of <Emphasis Type="Italic">Mycoplasma hyopneumoniae</Emphasis> seroconversion and infection in pigs in the three main production systems     

Enrico Giacomini  Nicola Ferrari  Alessandra Pitozzi  Michela Remistani  Daniele Giardiello  Dominiek Maes  Giovanni Loris Alborali 《Veterinary research communications》2016,40(2):81-88

In this study, we investigated the dynamics of Mycoplasma hyopneumoniae infections in 66 pig farms, with different production systems (one-, two-, and three-site systems), and considered different risk factors. Serological assay was used to detect serum antibodies against M. hyopneumoniae and real time polymerase chain reaction (RT–PCR) was performed to detect M. hyopneumoniae DNA in tracheobronchial swabs. Results demonstrated that M. hyopneumoniae infection status was predominantly influenced by the age of the animals and the type of production system. Infection rates were higher in older animals and the prevalence was higher in the one- and two-site systems than in the three-site systems. Dynamics of infection by RT-PCR showed that earlier M. hyopneumoniae infection on one-site farms occurs earlier, while on two- and three-site farms occurs later but spreads faster, suggesting that contact between animals of different age favors the transmission.  相似文献

Cultivar influence on virgin olive (Olea europea L.) oil flavor based on aromatic compounds and sensorial profile     

Debora Tura  Osvaldo Failla  Daniele Bassi  Stefano Pedò  Arnaldo Serraiocco 《Scientia Horticulturae》2008

Sensory quality is an important property of virgin olive oil and is affected by different volatile and phenolic compounds. Their levels may be influenced by many factors, and one of the most important is the cultivar. Volatiles and phenols were correlated to sensory notes in virgin olive oils from 18 local cultivars in northern Italy assessed for 4 years in the same orchard.  相似文献   

Increasing levels of supplementation for crossbred steers on pasture during the dry period of the year

The aim of this study was to evaluate the effect of increasing concentrate supplementation levels on the intake, nutrient digestibility, and performance of crossbred steers during the dry period of the year. The experiment was developed on Princesa do Mateiro farm, in the municipality of Ribeirão do Largo, located in the southwest region of Bahia State, Brazil. Forty uncastrated male crossbred (½ Holstein-Zebu) steers with an average body weight (BW) of 232.55?±?24.97 kg were distributed into four treatments in a completely randomized design with ten replicates. The animals were managed in an experimental area formed by Brachiaria brizantha cv. Marandu, in an intermittent grazing system. Treatments consisted of the following supplementation levels: 0.2% BW, with 60% crude protein (CP); 0.3% BW, with 40% CP; 0.4% BW, with 30% CP; and 0.5% BW, with 24% CP. The intakes of forage dry matter in kg/day and %BW and neutral detergent fiber corrected for ash and protein (NDFap) in %BW decreased linearly, whereas the intake of non-fibrous carbohydrates corrected for ash and protein in kg/day and average daily gain increased linearly. Therefore, the use of supplementation at 0.5% BW (24% crude protein) to provide gains of up to 0.500 kg/day is recommended for grazing steers during the post-weaning period in the dry season of the year.  相似文献
