The Effect of Varying Protein Intake on TRICHINELLA SPIRALIS Infection in Mice
… placed on low (8%), medium (24%), high (48%) protein levels and a commercial laboratory animal feed, Purina Chow for various lengths of time: (1) simultaneously with infection, and four weeks thereafter, (2) three weeks before infection and throughout the four-week infection period, and (3) …

A study of the protein metabolism of a two-year old on two levels of plant protein intake
… of two diets providing 24 and 16 gm. of plant-protein daily and to approach the approximate minimum protein requirement using plant proteins for a 23-month old Chinese girl weighing 12 kg. The diets were supplemented to bring nutrients to the NRC recommended allowances except for protein and …

Iron status and behavioral factors relative to dietary source of protein intake among female athletes at Virginia Tech
… among those whose primary source of dietary protein was red meat (M), lacto-ovovegetarian (V), or poultry and fish (PF). Subjects' blood was collected three times over the six-month study period and analyzed for hemoglobin, hematocrit, serum iron, transferrin saturation, total iron~binding …

Influence of Dietary Protein Intake on the Molecular Aspects of 7,12-Dimethylbenz(a)anthracene Induced Mammary Carcinogenesis (Cancer, Liver)
The influence of prior protein intake in rats on the metabolism and DNA-binding of 7,12-dimethylbenz(a)anthracene (DMBA) by their isolated mammary epithelial cell aggregates was examined. DMBA was metabolized to bay-region anti- and syn- dihydrodiol-epoxides that bound to deoxyadenosine and …

The effect of protein intake on the excretion of vitamin B₆, 4-pyridoxic acid, and xanthurenic acid in preadolescent boys
The effect of protein intake on vitamin B<sub>6</sub> status was investigated in preadolescent boys. Twelve subjects rotated through a diet sequence containing daily intakes of 1.15 mg vitamin B<sub>6</sub> and 29, 54, or 84 rim protein. Total vitamin B<sub>6</sub> and 4-pyridoxic acid were …

A food-based approach to increase egg and protein intake in community dwelling British older adults aged over 55 years old.
Dietary protein has an important impact on health, physical functioning, and muscle mass, and the prevalence of protein specific under-nutrition is high among older adults. Eggs are a nutrient dense, high quality source of protein. Compared to other protein rich foods, eggs are easy to cook, of low …

The effects of dietary protein intake by the dam and by the offspring on mammary gland development in young female rats
… conducted to determine the effects of different intakes of dietary protein (casein) at different ages on mammary gland development in first generation female Sprague Dawley rats. Offspring were fed the same diet as fed to their dams during gestation and lactation, or offspring were crossed over …

The effect of non-weight-bearing exercise and protein intake during pregnancy on maternal and fetal zinc content in the Sprague-Dawley rat
To study the effect of exercise and protein intake during pregnancy on maternal and fetal zinc status in the rat, one hundred and seventy-nine pregnant Sprague-Dawley rats were divided into four groups; sedentary-standard protein diet, sedentary-high protein diet, exercising-standard protein diet …

Fetal programming in cattle: the effects of varying maternal protein intake in adolescent beef heifers on fetal and postnatal growth and development of the calf
… systems. In the northern Australian rangelands, protein, rather than energy, is the major limiting nutrient for cattle in dry-season pastures with protein supplementation of breeding heifers an animal husbandry requirement. Few studies in cattle have specifically evaluated the effects of maternal …

Macronutrient Intake, Growth Hormone-Releasing Factor and Somatostatin During Zinc Deficiency and Repletion in Rats
… each containing mixtures of carbohydrate (CHO), protein (PRO) or fat (FAT) made either adequate (Zn+) or deficient in zinc. After 28 days of free access to the diets, the Zn$-$ animals were allowed access to the Zn+ diets, termed 'zinc repletion'. Our results indicated that the reduction in total …

Assessment of nutritional status in patients with acquired immunodeficiency syndrome (AIDS)
… levels were measured to estimate visceral protein stores. The average Kilocalorie and protein intake was assessed from four day records and compared to estimated Kilocalorie and protein needs. The findings of this assessment showed decreased skeletal and visceral protein stores that can be …

Establishing Urinary Biomarkers as Objective Indicators of Dietary Intake In Adolescents
… in 2013-2014. Quality and quantity of dietary intake contribute to the development of obesity, but limitations of self-reported dietary intake are evident in overweight or obese adolescents, who frequently misreport nutrients of concern. Added sugar, sodium, and protein intake may indicate diet …

The effects of different levels of dietary protein on the toxicity and metabolism of malathion and parathion and their oxygen analogues
… in rats fed different levels of dietary protein. Male weanling rats were pair-fed either 5 or 20% casein diets for 10 days and control animals received a 20% casein diet ad libitum. Toxicity studies showed that rats which received 5% casein diets were more susceptible to malathion and …

Skeletal muscle mass, function, and metabolic regulation between menopause stages in moderately active mid-life females
… accounting for age, physical activity and protein intake. While total and appendicular lean mass were comparable across groups, rectus femoris muscle thickness was significantly smaller in post-menopause (1516%) compared to pre- and peri-menopause, indicating a muscle specific decline …

Evaluation of Methods for Improving Phytate Phosphorus Utilization in Poultry and Swine
… to determine if phytase would increase the protein efficiency ratio (PER) values (g weight gain per g protein intake) for 10 ingredients fed to chicks. Phytase (1200 U/kg) did not improve (P > 0.10) PER values for any of the ingredients evaluated, thereby indicating that phytase did not …

Protein feeding and exercise recovery
The importance of protein feeding for maximising the anabolic effect of resistance exercise is well established. Ingestion of amino acids or intact protein sources with and without carbohydrate during exercise recovery further stimulates muscle protein synthesis. Less clear is the impact of an …

The effect of condensed tannins on goats’ body weight
… Condensed tannins have a potential to bind proteins, reduce the feed intake and consequently reduce the body weight gain of goats. The study was conducted in order to determine the effects of different condensed tannin concentrations on the body weight gain of goats. The first experiment was …

Dietary protein and bone health: Harmonizing conflicting theories
No clear consensus on the role of higher protein intakes has emerged, in spite of many decades of research. Protein unambiguously increases urinary calcium losses, which is completely attributable to the dietary acid load imposed by metabolism of sulfur containing amino acids into acid equivalents. …
