Effect of Dietary Restriction on Muscle Performance in Drosophila
Dietary restriction (DR) can extend the lifespan in various organisms and is thought to present potential benefits in human. However, it is still a controversial issue now among scientists due to lack of strong supportive evidence in human. Aging is an important issue in every developed country, …

Establishing a role for specific nutrients in Drosophila dietary restriction
Dietary restriction (DR), the reduction in food intake that falls short of starvation, has been shown to be the most robust and reproducible intervention to extend lifespan in diverse organisms ranging from yeast to mammals, including the fruit fly Drosophila. Despite over 70 years of research, …

Genetic regulation of dietary restriction-induced longevity in Caenorhabditis elegans
Dietary restriction (DR), the limitation of food intake below the ad libidum (AL) level without malnutrition, extends mean and maximum lifespan in every organism in which it has been tested. Perhaps even more significantly, DR has also been shown in animal models to slow progression of, or even …

Elucidation of the molecular pathways of lifespan extension by dietary restriction in yeast
In this dissertation, we demonstrate strong support for the antagonistic pleiotropy view of aging, reveal the illusion of sirtuin mediated longevity in 32 long lived alleles (hopefully steering the field farther from sirtuin research and toward more interesting things), show that there is indeed a …

Novel effects of Prefoldin Pathway on Intestinal Homeostasis via Dietary Restriction in Drosophila melanogaster
<p>The field of medicine research is embroiled in a battle against aging. Particular focus is on the extension of lifespan and health-span. Lifespan duration is affected by many factors, one of which is the maintenance of the intestines of the organism. Homeostasis of the intestines is controlled …

Genetic Mechanisms Responsible for Dietary Restriction Dependent Lifespan Extension in Drosophila Melanogaster: A Role for Muscle Tissue
<p>Dietary Restriction (DR) is a robust intervention that is known to extend lifespan and increase spontaneous activity in multiple species. Whether activity increase plays a causal role in mediating the health protective benefits of DR remains unknown. To investigate this relationship, nutritional …

Serum lipid concentrations during DMBA-induced mammary carcinogenesis of rats fed diets of different types of protein with 20% dietary restriction
… libitum group, casein diet (C-AL) and four 20% dietary restricted groups fed soy protein isolate diet, (SPI-R), defatted cottonseed flour diet (CS-R), wheat gluten diet (W-R), and casein diet (C-R). Serum TC, HDL-C, and TG concentrations were also determined at one week post DMBA and sesame oil …

Bowel preparation for colonoscopy: is diet restriction necessary?
… most bowel preparation regimens recommend dietary restriction for 24 to 48 hours before the procedure, the evidence for this is poor. Objectives: To establish whether dietary restriction during bowel preparation improves the quality of bowel preparation. Methods: A prospective single blind, …

The impact of maternal overnutrition during the periconceptional period on the development of postnatal obesity in the sheep.
… mass in the offspring and whether a period of dietary restriction in overnourished mothers reverses these changes. Non pregnant ewes (n=23) were randomly assigned to one of four treatment groups, either control-control (CC) maintained at 100% maintenance energy requirements (MER) for at least 5 …

Management and nutrition of the replacement gilt.
… long- (chronic) and short- (acute) term moderate dietary restriction on ovarian development and oocyte developmental competence in 161- and 175- day old, pre-pubertal gilts. Both chronic and acute periods of moderate feed restriction reduced the number of medium follicles present on the ovaries of …

Characterization of the IGF system in food-restricted pregnant and lactating rats: Role of IGF-I in nutrient partitioning
… the role of the IGF-I in adaptation to dietary restriction, the experiments reported herein determined the changes in the circulating levels, as well as, in the gene expression of IGF-I and IGFBPs in pregnant and lactating rats which were food restricted during pregnancy and lactation or …

Alterations in Vitamin a and Thyroid Hormone Metabolism in Anorexia Nervosa and Associated Disorders
… were divided according to eating behavior, i.e., dietary restriction or bulimia; and by level of serum carotene. This subdivision resulted in three groups: Group I, dietary restricters, normal serum carotene; Group II, dietary restricters, elevated serum carotene; and Group III, bulimic, elevated …

Aggressive Behavioral Phenotype in Intrauterine Growth Restricted (IUGR) Baboons Exposed to Moderate Nutrient Restriction Early in Development
… between aggression and intrauterine growth restriction (IUGR), which can result from low maternal food intake during pregnancy. The main hypotheses of this study are [1] IUGR offspring demonstrate higher rates of aggressive behavior and [2] IUGR offspring attain higher ranks. Behavioral …

The effect of ethanol consumption on the development of the female rat mammary gland
… carcinogen-treated (NMU) rat, consumption of dietary ethanol was associated with a significant increase in carcinogen-sensitive TEB and TD structures and a concomitant decrease in carcinogen-insensitive AVB structures. In addition, normal mammary gland TEB DNA-LI also was increased at 20% and …

A Comparison of the Manipulations of Dopaminergic, Opioidergic or Serotonergic Systems within the Nucleus Acccumbens on the Cue-Evoked Relapse to Food-Seeking

The Phenomenology of Fat Men's Health
… healthist values, such as losing weight through dietary restriction and increased physical activity, whereas others are unable or unwilling to perform these practices. Three major themes emerged from the data a) bodily ambivalence throughout weight loss b) Physical and social exclusion c) fat …

Femininity, Feminine Gender Role Stress, Body Dissatisfaction, and their Relationships to Bulimia Nervosa and Binge Eating Disorder
… and the main difference between the two is the dietary restriction, while others see them as distinct disorders with different etiology. A total of 355 female college students (ages 18 to 26) completed a set of questionnaires that assessed femininity, feminine gender role stress, body …

The Effects of Low Energy Availability and High-Impact Exercise on Bone and Body Composition
… energy availability (EA) describes the amount of dietary energy intake (EI) that is remaining to support physiological function after accounting for the energy cost of exercise. Exposure to LEA stimulates metabolic adaptations that may disrupt certain biological systems, such as endocrine …

Influences of nutrition and pathogenicity from a microbial diet on immunity and longevity in Caenorhabditis elegans
