In vitro and in vivo studies of the health and nutritional properties of durian (Durio zibethinus Murr.) were compared with snake fruit (Salacca edulis Reinw.) and mangosteen (Garcinia mangostana). Dietary fibers, minerals, and trace metals were comparable. Total polyphenols (mg of GAE/100 g of FW) and flavonoids (85.1+/-6.1) were significantly higher (p<0.05) than in snake fruit (217.1+/-13.2 (mg of CE/100 g of FW)), durian (309.7+/-19.3 and 61.2+/-4.9), and mangosteen (190.3+/-12.1 and 54.1+/-3.8). Antioxidant activity (microM TE/100 g of FW) of durian measured by DPPH and ABTS assays (228.2+/-13.4 and 2016.3+/-81.1) was significantly higher (p<0.05) than in snake fruit (110.4+/-7.9 and 1507.5+/-70.1) and mangosteen (79.1+/-5.9 and 1268.6+/-62.3). HPLC/DAD analysis of durian (microg/100 g of FW) showed that quercetin (1214.23+/-116.7) was present at levels three times that of caffeic acid, and twice as high as p-coumaric and cinnamic acids. The correlation coefficients between the bioactive compounds of fruits and their antioxidant activities were high (R2=0.99). Male Wistar rats (25) were divided into five dietary groups: the control group was fed the basal diet (BD); in addition to BD, the cholesterol (Chol) group was supplemented with 1% of Chol; the diets of the Chol/Durian, Chol/Snake, and Chol/Mangosteen groups were supplemanted with 5% of these fruits, respectively. It was found that diets supplemented with durian, and to a lesser degree with snake fruit and mangosteen, significantly hindered the rise in plasma lipids and the decrease in antioxidant activity. The nutritional values were comparably high. In conclusion, it could be suggested that inclusion of studied tropical fruits, especially durian, in known disease-preventing diets could be beneficial.  相似文献   

Properties of low-moisture viscoplastic materials consisting of oil droplets dispersed in a protein-carbohydrate-glycerol matrix: effect of oil concentration     

Gu YS  Corradini MG  McClements DJ  DesRochers J 《Journal of agricultural and food chemistry》2007,55(22):9289-9295

The influence of oil concentration and baking on the properties of low-moisture composites consisting of oil droplets dispersed in a protein-carbohydrate-glycerol matrix was investigated. These composites were produced by blending canola oil, whey protein concentrate (WPC), corn syrup, and glycerol together using a high-speed mixer. The resulting system consisted of oil droplets dispersed in a polar matrix. Some composites were analyzed directly after preparation, while others were analyzed after being heated at 176 degrees C for 10 min to simulate baking. The "lightness" of the composites was greater before baking (higher L value), but the color was more intense after baking (higher a and b values). The lightness and color intensity of the composites decreased as the oil concentration increased, with the effects being more pronounced in the baked samples. The zeta potential of the oil droplets (measured after dilution at pH 6) was highly negative (approximately -40 mV), indicating that whey protein was adsorbed to the droplet surfaces. The mean particle diameter (measured after dilution at pH 6) increased appreciably after baking, which was attributed to droplet flocculation. The rheological properties of the unbaked and baked materials were characterized by squeezing flow viscometry, which showed that the measurements associated with consistency and yield stress increased with increasing oil concentration and with baking.  相似文献

Comparison of 2 blind approaches to the paravertebral brachial plexus regional block in canine cadavers     

Maria Podsiedlik  Erik H. Hofmeister  Tanya Duke-Novakovski 《Canadian journal of veterinary research》2022,86(1):20

The paravertebral brachial plexus block (PVB) provides thoracic limb analgesia. The objective was to describe a blind craniocaudal (CC) approach to the PVB and compare its accuracy, time, and difficulty of performance with a blind dorsoventral (DV) approach. The operator was initially trained by experienced clinicians to perform both approaches on 5 cadavers. Next, a CC or DV approach to the PVB was performed on both thoracic limbs of 20 cadavers (20 for each approach). Methylene blue dye was equally divided into 4 aliquots to stain the ventral branches of the sixth to eighth cervical and first thoracic spinal nerves. Successfully stained (stain ≥ 1 cm) spinal nerves were counted. The time to perform each approach was recorded and ease of performance was scored using a numerical scale (1 “easy” to 4 “difficult”). The phrenic nerve was checked for stain. A Wilcoxon signed-rank test was used to compare approaches. The data are presented as median (interquartile range; minimum to maximum range). The number of stained nerves with the CC approach 3 (1; 2 to 4), was higher than the DV approach 2 (2; 0 to 4) (P = 0.002). The time (in seconds) to perform the CC approach 125 (79; 70 to 194), was not different from the DV approach 142 (54; 101 to 232) (P = 0.084). The CC approach 2 (2; 1 to 4) was easier to perform than the DV approach 3 (1; 2 to 4) (P = 0.024). No phrenic nerve staining was observed with either approach. The CC approach is an alternative to the DV approach for performing the PVB in dogs.  相似文献   

Potential Anti-Obesity,Anti-Steatosis,and Anti-Inflammatory Properties of Extracts from the Microalgae Chlorella vulgaris and Chlorococcum amblystomatis under Different Growth Conditions

Microalgae are known as a producer of proteins and lipids, but also of valuable compounds for human health benefits (e.g., polyunsaturated fatty acids (PUFAs); minerals, vitamins, or other compounds). The overall objective of this research was to prospect novel products, such as nutraceuticals from microalgae, for application in human health, particularly for metabolic diseases. Chlorella vulgaris and Chlorococcum amblystomatis were grown autotrophically, and C. vulgaris was additionally grown heterotrophically. Microalgae biomass was extracted using organic solvents (dichloromethane, ethanol, ethanol with ultrasound-assisted extraction). Those extracts were evaluated for their bioactivities, toxicity, and metabolite profile. Some of the extracts reduced the neutral lipid content using the zebrafish larvae fat metabolism assay, reduced lipid accumulation in fatty-acid-overloaded HepG2 liver cells, or decreased the LPS-induced inflammation reaction in RAW264.7 macrophages. Toxicity was not observed in the MTT assay in vitro or by the appearance of lethality or malformations in zebrafish larvae in vivo. Differences in metabolite profiles of microalgae extracts obtained by UPLC-LC-MS/MS and GNPS analyses revealed unique compounds in the active extracts, whose majority did not have a match in mass spectrometry databases and could be potentially novel compounds. In conclusion, microalgae extracts demonstrated anti-obesity, anti-steatosis, and anti-inflammatory activities and could be valuable resources for developing future nutraceuticals. In particular, the ultrasound-assisted ethanolic extract of the heterotrophic C. vulgaris significantly enhanced the anti-obesity activity and demonstrated that the alteration of culture conditions is a valuable approach to increase the production of high-value compounds.  相似文献

The ectomycorrhizal status of European larch (Larix decidua Mill.) seedlings from bare-root forest nurseries     

Tomasz Leski  Maria Rudawska  Algis Aučina 《Forest Ecology and Management》2008

In this paper, we report molecular investigation of an ectomycorrhizal fungi (EMF) community of European larch (Larix decidua Mill.) seedlings grown in a bare-root nursery. In total, we surveyed 32 nurseries that were each active in supplying planting stocks to restock forests and for afforestation of post-agricultural land. Sequence-based approach was used to identify EMF taxa, quantify EMF richness, and document differences in the relative abundance of individual taxa. We identified seven fungal species that might contribute to the mycorrhizal community structure of 1 to 3-year-old L. decidua seedlings. The species richness in the examined larches varied between one and four fungal taxa, depending on both the nursery stock samples (NSS) and age class of the seedlings. The average was 1.4 for 1-year-old seedlings and 2.3 for 2- and 3-year-old plants. The dominance of Ascomycota over Basidiomycota and the prevalence of two species, Wilcoxina mikolae and Suillus grevillei, as EMF partners were characteristic features of nursery-grown L. decidua seedlings. S. grevillei was the only one basidiomycetes colonized roots of tested seedlings. The rest of the mycorrhizal pool from forest nurseries was typically dominated by pioneer fungal ascomycetes. W. mikolae was the most common mycorrhizal ascomycete present at a high frequency on NSS from both age classes and with very high abundance (average 90%) on 1-year-old seedlings. Some other ascomycetes (Pezizales 1, Pezizales 2 and Pezizales 3) appeared on tested larches at a low frequency, but sometimes in high abundance. Tuber spp. appeared at a low frequency and low abundance. The relative abundance of S. grevillei was positively correlated with the age of seedlings, while W. mikolae was negatively correlated with age. Tuber sp. 1 and 2, Pezizales 2, and W. mikolae were positively associated with the basic soil pH values. However, forward selection of the environmental variables showed that only the age of the larch seedlings contributed significantly (F = 11.45, P = 0.02) to the variance in the ECF community.  相似文献   

Backshoring and nearshoring: An overview     

Benedetta Piatanesi  Josep‐Maria Arauzo‐Carod 《Growth and change》2019,50(3):806-823

Increasingly, economies that have traditionally benefited from offshoring are losing some of their strategical advantages, with a consequent increase in backshoring by developed economies. This paper describes the phenomenon and tries to shed light on the current challenges, trends, and debates in the area, and on the main determinants of backshoring. A new phenomenon known as nearshoring is also analysed—this consists of relocating some previously offshored manufacturing activities so that they are now close to previous core locations, but not so close as to suffer from disagglomeration effects. This combines the advantages of offshoring and backshoring.  相似文献
