1. The kinetics of the reaction which takes place between glycine and iodoacetic acid was studied by means of the polarographic method. 2. On the basis of kinetic equations, evidence was obtained that (a) The reaction proceeds in two steps in which the hydrogens of the amino group are consecutively replaced by the acetyl radicals, the velocity constants being in the ratio 2:1. (b) Only the anio...

Lycopene in fruits and vegetables occurs mostly (80-97 %) in the all-E configuration, whereas a considerable proportion of lycopene in the human body is present as Z-isomers. The Z-isomers offer potentially better health benefits and show improved antioxidant activity in vitro when compared with the all-E-isomer. The absorption of dietary lycopene is a complex process involving transfer of the ...

Human immunodeficiency virus type 1 (HIV-1) infection is characterized by progressive depletion of CD4+ T lymphocytes and dysfunction of the immune system. The numbers of CD4+ T lymphocytes in the human body are maintained constantly by homeostatic mechanisms that failed during HIV-1 infection, resulting in progressive loss of CD4+ T cells mainly via apoptosis. Recently, a non-apoptotic form of...

BACKGROUND In patients with late dumping syndrome following gastrectomy, it has been reported that hypoglycemia occurs due to inhibition of glucagon secretion as a result of excessive insulin production facilitated by an increase in glucagon-like peptide-1 (GLP-1). METHODS To determine the kinetics of incretins in Japanese patients with late dumping syndrome, an oral glucose tolerance test wa...

BACKGROUND Nissen Fundoplication is a common surgical procedure performed in treating gastroesophageal reflux disease (GERD). Complications include dysphagia, gastric hypersensitivity, abnormal gastric motility, gas bloat syndrome and GERD relapse. Dumping syndrome may occur when a large volume of gastric content is delivered to the duodenum or jejunum, resulting in both gastrointestinal and va...

Bariatric surgery is most commonly carried out in women of childbearing age. Whilst fertility rates are improved, pregnancy following bariatric surgery poses several challenges. Whilst rates of many adverse maternal and foetal outcomes in obese women are reduced after bariatric surgery, pregnancy is best avoided for 12-24 months to reduce the potential risk of intrauterine growth retardation. D...

BACKGROUND Lesser omental transection during gastric bypass for morbid obesity may be associated with postoperative dumping. A survey of postoperative symptoms was performed in patients undergoing laparoscopic Roux-en-Y gastric bypass with transection vs. preservation of the lesser omentum. METHODS A written questionnaire on dumping symptoms was administered to patients 2 years after laparosc...

in the global village of today, more people have been moving and migrating than ever before creating a need for better communication. thus community interpreting rose as a specialization serving the needs of members of the community who are unable to communicate with the system. within this broad field of interpreting the specialist area of legal interpreting assumed a high position. however, l...

extended distribution of digicash has commercial, socio-economic as well as political effects. from the economic viewpoint, the most crucial effect of digicash use extension takes place on money supply, monetary policies and central bank. because digicash is capable of being replaced by bank notes and the coins, it is possible that digicash gradually takes the place of the central bank money an...
