1. The acute hepatotoxic action of dimethylnitrosamine was investigated with homogenates and mitochondrial preparations from the livers of rats injected with 100 mg./kg. body weight at various times between 8 and 24 hr. before killing. 2. Aerobic oxidation of pyruvate, octanoate, L-malate, citrate, L-glutamate, a-oxoglutarate and ,-hydroxybutyrate progressively decreased after the twelfth hour ...

The relation of tissue mast cells to immune reactions, particularly anaphylaxis, has been the subject of extensive investigation and speculation in recent years. It is generally agreed that a variety of pharmacologically active substances are involved in the pathogenesis of anaphylaxis, that many of these substances are stored in tissue mast cells, and that anaphylaxis in many species is mediat...

I have a family history of diabetes, so I try and control my sugar intake. I am having a lot of trouble figuring out how much sugar is the maximum amount of sugar to allow in my diet. I have read that "added sugar" intake should be limited to no more than ten percent of your daily calories, but I have no idea how to determine what amount of sugar in food is natural versus added. I assume that a...

We investigated the mechanisms of the protection conferred by sugars to epigallocatechin-3-gallate (EGCG) against deterioration. Additionally, we present a rapid method for evaluating the deterioration rate of EGCG using absorbance spectroscopy. We found that various sugars provided different levels of protection at identical weight percentage, and the combination of sugars and β-lactoglobulin ...

Dental caries is a highly prevalent chronic disease and its consequences cause a lot of pain and suffering. Sugars, particularly sucrose, are the most important dietary aetiological cause of caries. Both the frequency of consumption and total amount of sugars is important in the aetiology of caries. The evidence establishing sugars as an aetiological factor in dental caries is overwhelming. The...

environmental stresses such as drought have important effects on plant growth and development. in order to evaluate the effect of drought tolerance, 12 chickpea genotypes were treated with drought stress in hydroponic condition in greenhouses. treatments were a control and two stress treatments -3 and -6 bar that was created with polyethylene glycol in hydroponic condition. two weeks after the ...

Sugar consumption, especially added sugars, is under attack. Various government and health authorities have suggested new sugar recommendations and guidelines as low as 5% of total calories from free sugars. Definitions for total sugars, free sugars, and added sugars are not standardized, nor are there accepted nutrient databases for this information. Our objective was to measure total sugars a...

Guidelines for sugars intake range from a population mean of less than 10 % energy from free sugars, to a maximum for individuals of 25 % energy from added sugars. The aim of the present review was to examine the evidence for micronutrient dilution by sugars and evaluate its nutritional significance. From a web-based search of MEDLINE and hand search of linked papers, forty-eight relevant publi...

Soluble sugars play an important role in freezing tolerance in both herbaceous and woody plants, functioning in both the reduction of freezing-induced dehydration and the cryoprotection of cellular constituents. The quantification of soluble sugars in plant tissues is, therefore, essential in understanding freezing tolerance. While a number of analytical techniques and methods have been used to...
