Cantaloupe cultivar variability from various U.S. regions and growing seasons within a given year was evaluated. As expected, there was often considerable quality and volatile variation among cultivars. Eight of 11 cultivars met the standard U.S. No. 1 requirement for degrees Brix (> or =9), and in most cultivars, degrees Brix declined during fresh-cut storage at 4 degrees C. Hunter L (loss of ...
(-)-Bornyl acetate is the main volatile constituent in numerous conifer oils and has a camphoraceous, pine-needle-like odor. It is frequently used as the conifer needle composition in soap, bath products, room sprays, and pharmaceutical products. However, the psychophysiological effects of (-)-bornyl acetate remained unclear. We investigated the effects of breathing air mixed with (-)-bornyl ac...
High oxygen concentrations induced visual cell degeneration in albino and pigmented rabbits. The most sensitive cells were located in the area centralis, a zone analogous to the human macula, and characterized by low glycogen content and rich choroidal blood supply. Electron microscopy demonstrated early pathological changes of intracellular membranes followed by total disorganization of visual...
OBJECTIVE Our aim was to examine the impact of a single enteral dose of vitamin E on serum tocopherol levels. The study was undertaken to see whether a single dose of vitamin E soon after birth can rapidly increase the low α-tocopherol levels seen in very preterm infants. If so, this intervention could be tested as a means of reducing the risk of intracranial hemorrhage. METHODS Ninety-three ...
To evaluate meat quality of beef with different α-tocopherol tissue levels, 55 feedlot steers were fed a barley-based finisher diet with four vitamin E supplementation levels (0, 350, 700 and 1400 IU DL-α-tocopheryl acetate/animal per day) for 120 days. Although the increase in oxidation levels overtime was much smaller (P < 0.001) in the high-medium and high groups, α-tocopherol tissue levels ...
Twelve (Yorkshire) gilts were assigned to 2 dietary fat supplement groups starting at 57 d of gestation. Group 1 received no fat and Group 2 was supplemented with 5% Canola oil. Each group was supplemented with 0.1 ppm Se and 22 IU of DL-alpha-tocopherol acetate/kg of feed. Colostrum (d 0) and milk (7, 14, 21 and 28 d post partum) were sampled from gilts. At farrowing 3 piglets from each gilt o...
Intrapulmonary administration of bacterial lipopolysaccharide (LPS) induces a well-characterized lung inflammatory response involving alveolar macrophage activation, proinflammatory cytokine elaboration, and neutrophil influx. Vitamin E, a lipophilic antioxidant consisting of a family that includes tocopherols and tocotrienols, has previously been shown to have a variety of anti-inflammatory ef...
PURPOSE The vitamin E compound alpha-tocopherol inhibits fibroblast growth in vitro. To evaluate its potential benefit in preventing failure of glaucoma filtration surgery, we prospectively investigated the outcome of filtering surgery with postoperative dietary alpha-tocopherol supplementation. PATIENTS AND METHODS Thirty-nine patients (39 eyes) with primary open-angle glaucoma or pseudoexfo...
A 2 x 2 trial was conducted to determine the effects of injected vitamin A and dietary level of vitamin E on blood serum and tissue concentrations of alpha-tocopherol during early gestation of gilts. Thirty-two crossbred gilts were fed a corn soybean meal basal diet supplemented with DL-alpha tocopheryl acetate to provide either 25 or 500 IU of vitamin E/kg of diet. Gilts were fed daily 1.9 kg/...
Anti-oxidant effects of propofol (2, 6-diisopropylphenol) were evaluated agains carbon tetrachloridet CCl4 -induced oxidative stress in rat liver. 30 male rats were equally divided in to 6 groups (5 rats each). Group I (control), while Group II was given CCl4 (3 mL /Kg/day, IP). Animals of Groups III received only propofol (10 mg/Kg/day, IP). Group IV was given propofol+ CCl4. Group V was admin...
