BACKGROUND Adjustments of carbohydrate intake and oxidation occur in both normal-weight and overweight individuals. Nevertheless, the contribution of carbohydrates to the accumulation of fat through either reduction of fat oxidation or stimulation of fat synthesis in obesity remains poorly investigated. OBJECTIVE The objective of this study was to assess the postprandial metabolic changes and...

background: premenstrual syndrome (pms) is one of the most common disorders in women in reproductive age. the study aimed to assess the effect of carbohydrate-rich supplements and diets on premenstrual syndrome. methods: the study was conducted within two stages. first stage was descriptive cross sectional investigation to find out frequency and subjects diagnosed as pms according to the apa cr...

Low-carbohydrate diets are used to manage obesity, seizure disorders, and malignancies of the central nervous system. These diets create a distinctive, but incompletely defined, cellular, molecular, and integrated metabolic state. Here, we determine the systemic and hepatic effects of long-term administration of a very low-carbohydrate, low-protein, and high-fat ketogenic diet, serially compari...

Girdling effects on fruitlet abscission, leaf chlorophyll, chlorophyll a fluorescence and carbohydrate concentration in various flowering and vegetative shoots were studied during natural fruit drop in two Citrus cultivars. Irrespective of shoot type, girdling delayed fruitlet abscission, but only fruitlets borne on leafy shoots had increased final fruit set. Chlorophyll a fluorescence analysis...

Net photosynthetic rate, CO(2) compensation concentration, and starch and soluble sugar concentrations were measured in soybean (Glycine max [L.] Merrill) leaves in an attempt to evaluate the effect of carbohydrate concentration on rate of CO(2) assimilation.Plants were grown in a controlled environment room at 23.5 C, 50% relative humidity, 16-hour photoperiod, and quantum flux (400-700 nm) of...

• N addition alters chemical composition of soil organic matter in boreal forest. This is driven by increased lignin derivatives at the expense carbohydrate. Relative abundance microbial origin compounds increases with level. Boreal forests store approximately 470 Pg carbon (C) soil, and rates C accumulation are significantly enhanced long-term nitrogen (N) enrichment. Dissecting compositional ...
