Earlier studies from this and other laboratories have shown that the presence of glucose inhibits the formation of certain inducible enzymes in bacteria (Boyd and Lichstein, 1955; Magasanik, 1957). This phenomenon is not specific to glucose, but rather is shared by other carbohydrates utilized by the bacterial cells. Although several mechanisms have been proposed to explain this carbohydrate ef...

Chemical glycomics uses synthetic chemistry to procure defined carbohydrate molecules to study the glycans involved in many functions in the living cell. Based on an automated synthesis platform, a host of synthetic tools including carbohydrate microarrays has been developed. These tools have been employed to dissect carbohydrate-copolymer interactions. Basic research in the glycomics arena is ...

stress management is considered as an important factor in nowadays landscape. therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (lolium...

background: we investigated the efficacy of a mobile-based  bolus advisor app in comparison with the usual multiple daily  injections (mdis) in diabetic patients. materials and methods: in a nonrandomized, controlled clinical trial, 62 diabetic patients  were selected to receive a 12-week intensive glycemic control by either a mobile-based bolus advisor (app) or mdi in the usual manner.we compa...

information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. this information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. effects of various plant parts’phenological stages and vegetation types on reserve carboh...

background: lack of information regarding biochemical changes in women during labor and its outcomes on maternal and neonatal health still is an unanswered question. this study aims to explore the effectiveness of oral carbohydrate intake during labor on the duration of the active phase and other maternal and neonatal outcomes. methods: a parallel prospective randomized controlled trial, conduc...

background: nowadays it is proofed that the uterine artery plays essential role in follicular growth and/or post parturition hemorrhagic. objective: this study was conducted to evaluate the effect of bilateral uterine artery ligation (bual) on follicular fate and the probable histochemical changes of the carbohydrate and lipids in the ovaries of rabbits. materials and methods: 24 mature female ...

Approximately 15 per cent of the light chains from homogeneous immunoglobulins in patients with multiple myeloma contain an oligosaccharide group. Five human myeloma light chains that contained carbohydrate were studied. The sequence Asn-[unk]-Ser/Thr was at the site of carbohydrate attachment in all light chains. The carbohydrate group was attached to the asparagine residue of this triplet seq...

The inner carbohydrate was resistant to enzymatic attack and consisted of about one-third of the total mannose and one-half of the total iV-acetylglucosamine residues. It was shown that the carbohydrate chain was not attached to serine or threonine and that it is probably linked to asparagine. The cx and p anomeric forms of galactose were present in about a 1: 1 ratio. Glycopeptides containing ...
