  • The purpose of this research was to find effects of high fat diet and endurance exercise on mitochondria biosynthesis and insulin resistance in male Wister rat. Th rats were randomly separated into 4 groups: A, Isocaloric high fat diet group (50% of calories from fat), B. Chow group, C. Isocaloric high fat diet with endurance exercise (treadmill running, slop 8%, 23 m/min, 120 min/day, 5 days per week), D. Chow group with endurance exercise. Both Isocaloric high fat diet group and chow group were given an equal caloric composition with 3.2kcal/g. equal amount of food were checked every day and given to both groups. 4 weeks of high fat diet did not show any change in body weight and amount of body fat. Further the level of glucose and insulin in blood, and insulin-stimuilated glucose transport rate in epitrochlearis muscle was not affected by Isocaloric high fat diet. However, the endurance exercise showed statistically significant change in the level of insulin in blood. Although either Isocaloric high fat diet or endurance exercise alone did not change on mitochondria biogenesis marker, Isocaloric high fat diet with endurance exercise could induce the increased level of marker (p<0.05). Also, plasma free fatty acids were increased in this group. From this investigation, Isocaloric high fat diet with moderate-intensity endurance exercise is effective way to induce mitochondrial biogenesis.

  • A study was carried out to investigate the effect of palm oil supplementation on the growth, carcass composition and fatty acid distributions of the broilers fed isonitrogenous and isocaloric diets. This study showed that palm oil supplementation increased feed consumption, weight gain and nitrogen intake. Feed conversion improved at higher fat inclusions, but not significant. Male birds consumed significantly more feed than females resulting in significant increase in energy consumption and weight gain. Increaseing fat content in the ME:P constant diet did not produce significant difference in the fat content of the chicken. Fatty acids content of the diet exert varying effects of the composition and distribution of fatty acids in muscles of the chicken. The fatty acids found in larger amount in the breast and thigh muscles were palmitic, oleic and linoleic. The fatty acids of the breast and thigh muscles were found to correspond the fatty acids of the diets. There were no differences in the fatty acids distribution patterns between the sexes.

  • This experiment was conducted to study the effects of dietary zinc and ethanol on the zinc content of serum and tissues. Eight male rats of Sprague-Dawley strain with average weight of 80$\pm$5g were divided into five groups such as C group: ad libitum control diet(100 ppm Zn) plus isocaloric sucrose solution CE group ; ad libitum control diet plus 25% ethanol solution PF group ; pair fed control to zinc deficient diet(5ppm Zn) plus isocaloric sucrose solution ZD grop ; ad libitum zinc deficient diet plus isocaloric sucrose solution and ZDE group ; ad libitum zinc deficient diet plus 25% ethanol solution. The rats were sacrificed after 4 and 7 weeks of feeding periods. The liver weights of ZD and ZDF groups were increased however the weight of testis was decreased in the same groups The content of serum zinc was infiuenced by the dietary zinc level and the amount was significantly decreased in the ZD group. The content of liver zinc was influnced by the dietary zinc level and the amount was decreased by ethanol feeding. The content of testis zinc was significantly low in the ZDE group. The zinc level of feces to be increased by the ethanol feeding.

  • The effects of palm oil and soybean oil as a high energy source diet on the performance of broilers under the warm humid environment were studied. Palm oil and soybean oil, either singly or mixed, were incorporated in the experimental diets to a total of 6% of the diet. The performance of the chicken improved (though not significant) with increasing unsaturated fatty acid content in the diets, but the responses to treatments were not consistent. The carcass fat content was generally higher in all the treated groups compared to the control but the differences were not statistically significant. The results also failed to show any effect of combining two sources of oils. Fatty acid composition in the body was found to be influenced greatly by dietary fat. When soybean oil was used instead of palm oil, the amount of linoleic and linolenic acids in the carcass were increased proportionately.

  • The reproductive performance of forty two male broilers divided into three similar groups and fed on isocaloric and isonitrogneous diets containing 0, 10 or 20% water washed neem seed kernel meal (WWNSKM) was investigated from 20 to 32-wks of age. Results on semen characteristics revealed that feeding of WWNSKM led to significant (p < 0.05) reduction in semen volume, sperm concentration associated with increased incidences of morphological abnormalities in the spermatozoa when compared to that of the control birds. A drastic reduction in the fertilizing ability of spermatozoa was observed, the adverse effects being more at higher inclusion level of the cake. Hatchability of eggs also declined in the WWNSKM fed group. Histological examination of testes revealed a higher number of degenerating cells and poor spermatogenesis along with multinucleated giant cells in the seminiferous tubules of the testes of birds receiving the high dose of WWNSKM in diet. It may be concluded that the feeding of WWNSKM by incorporating in isocaloric and isonitrogneous diets to cockerels is associated with adverse effect on their fertility.

  • In nutrition studies of fish, determining the optimum dietary protein level for growth of fish is generally a primary consideration because protein is not only the major constituent of fish body, but also it has critical functions as enzymes and hormones. Many studies have been carried out to determine the protein requirements of fish, and the estimated protein requirements range from 30% to 55% of diet. (omitted)

  • Background: Ventilator dependency constitutes a major problem in the intensive care setting. Malnutrition is considered a major determinant of extubation failure, however, attention has been attracted to modulating carbon dioxide production through decreasing carbohydrate loading and increasing the percent of fat in enteral feeds. The detected interrelation between substrate oxidation and ventilation outcome became the base of several research to determine the appropriate composition of the nonprotein calories of diet in ventilated patients. Purpose: We aimed to assess the effect of high-fat dietary modification and nutritional status on ventilatory and final outcomes of pediatric intensive care. Methods: Fifty-one ventilated children (1 month to 12 years of age) with pulmonary disease who could be enterally fed, in the Cairo University Pediatric intensive care unit, were divided into 2 groups: group A included 25 patients who received isocaloric high-fat, low-carbohydrate diet; group B included 26 patients who received standard isocaloric diet. Comprehensive nutritional assessment was done for all patients. Results: Group A had a significant reduction in carbon dioxide tension, but no similar reduction in the duration or level of ventilatory support. Assisted minute ventilation was predicted by weight-for-age and caloric intake rather than the type of diet. Poor nutritional status was associated with higher mortality and lower extubation rates. Mild hypertriglyceridemia and some gastrointestinal intolerance were significant in group A, with no impact on the adequacy of energy or protein delivery. Conclusion: The high-fat enteral feeding protocol may contribute to reducing carbon dioxide tension, with mild hypertriglyceridemia and negligible gastrointestinal intolerance as potential adverse effects. Optimization of nutritional status rather than dietary modification may improve ventilatory and survival outcomes in critically ill-ventilated children.

  • The current study was designed to evaluate the effect of sequential low and high dietary linseed oil (LO; as omega-3 enriched fatty acid; FA) before and post insemination, respectively, on different plasma variables of ewes. Fat-tailed Qezel ewes were assigned randomly to be fed a diet enriched with 3% LO (n = 30) or the saturated FA (SFA; n = 30) three weeks before insemination (Day 0). The lipogenic diet supplemented with 6% LO or SFA was fed after insemination until Day +21. The control ewes were fed an isocaloric and isonitrogenous diet with no additional FA during the study. Estrus was synchronized by inserting a vaginal sponge (Spongavet®) for 12 days + 500 IU equine chorionic gonadotropin (eCG; Gonaser®), and ewes were inseminated via laparoscopic approach 56-59 h after eCG injection. The size of ovarian structures was assessed by transvaginal ultrasonography at -21, -14, -2, 0, and +10 days. Blood samples were collected weekly to measure the plasma's different biochemical variables and FA profile. Treatment did not affect the amounts of glucose, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, interleukin-10, interleukin-2, and non-esterified FA (p > 0.05). Conversely, concentrations of triglyceride, cholesterol, tumor necrosis factor-alpha, and insulin-like growth factor-1 were higher in SFA-fed ewes relative to control animals (p < 0.05). LO feeding resulted in greater amounts of n-3 FA isomers in plasma, while higher amounts of stearic acid were detected in SFA fed group 0 and +21 (p < 0.05). The number of ovarian follicles and corpora lutea also were not affected by treatment. Other reproductive variables were not affected by treatment except for the reproductive rate. It seems that LO or SFA feeding of fat-tailed ewes peri-insemination period was not superior to the isocaloric non-additional fat diet provided for the control group during the non-breeding season.
