Use of glycosylated hemoglobin as a screen for macrosomia in gestational diabetes -- Baxi et al. 64 (3): 347 -- ... Glycosylated hemoglobin and blood sugar levels in the fasting state and two hours after oral 100 g glucose load were measured in 180 patients. Glycosylated hemoglobin was measured by cation exchange column chromatography, and blood sugar was measured by hexokinase reaction. Glycosylated hemoglobin values were elevated in 21 of 33 patients with gestational diabetes and in 27 of 147 patients with normal blood sugar levels. www.greenjournal.org /cgi/content/abstract/64/3/347   (266 words)

[No title]   (Site not responding. Last check: 2007-09-06) Demonstration of equal (or slightly better) biological activity by glycosylated leptin demonstrates either that (a) the glycosylated leptin enters the brain, or (b) if it doesn't, glycosylated leptin is more biologically effective in the peripheral tissues (such as visceral areas of adipose tissue) than native recombinant human leptin. Therefore, the present glycosylated leptin proteins are preferably those having at least a majority of the galactose moieties unavailable for binding to a galactose receptor, and more preferably, having a sialic acid moiety located at least a majority of the sites available for sialation. Glycosylation was accomplished via host cellular machinery, in cell culture, and therefore did not require an extra process step (as required to derivatize protein) to attain the desired characteristics of longer serum half life. www.wipo.int /cgi-pct/guest/getbykey5?KEY=00/47741.000817&ELEMENT_SET=DECL   (10420 words)

Glycosylated hemoglobin definition - Medical Dictionary definitions of popular medical terms Glycosylated hemoglobin is tested to monitor the long-term control of diabetes mellitus. The level of glycosylated hemoglobin is increased in the red blood cells of persons with poorly controlled diabetes mellitus. Glycosylated hemoglobin is also known as glycohemoglobin or as hemoglobin A1C (the main fraction of glycosylated hemoglobin). www.medterms.com /script/main/art.asp?articlekey=16295   (368 words)

HbA1c is a test that measures the amount of glycosylated hemoglobin in your blood. The percent of glycosylation increases over time, and is higher if there is more glucose in your blood. Therefore, older red blood cells will have a greater percent of glycosylated hemoglobin, and diabetics whose blood glucose has been too high will have a greater percent of glycosylated hemoglobin. health.allrefer.com /health/glycosylated-hemoglobin-info.html   (429 words)

Definition: Glycosylated Hemoglobin Test (Hemoglobin A1c) Hemoglobin is the substance inside red blood cells that carries oxygen to the cells of the body. Glucose (a type of sugar) molecules in the blood normally become stuck to hemoglobin molecules - this means the hemoglobin has become glycosylated (also referred to as hemoglobin A1c, or HbA1c). The glycosylated hemoglobin test shows what a person's average blood glucose level was for the 2 to 3 months before the test. kidshealth.org /parent/diabetes_basics/dictionary/hba1c.html   (184 words)

Hemoglobin   (Site not responding. Last check: 2007-09-06) The glycosylated hemoglobin test, or Hemoglobin A1c (HbA1c), is a test used to give you and your doctor the most accurate picture of your overall diabetes control. Sugar that is not used for energy is left in the blood, where it attaches itself to the hemoglobin, which is the part of the red blood cell that carries oxygen, in a process called glycosylation. So even though you may have had high blood sugar on occasion, a good glycosylated hemoglobin result can show that, overall, you are doing a good job of controlling your diabetes. www.endocrinologist.com /Hemoglobin.htm   (458 words)

British Journal of Pharmacology - Glycosylated human oxyhaemoglobin activates nuclear factor- Indeed, the so-formed Amadori adducts are the prominent form of circulating glycosylated proteins in vivo (Cohen, 1986). Other authors have also reported that, in diabetic patients, the presence of high levels of Amadori adducts, in particular glycosylated albumin, correlates with some markers of endothelial dysfunction and it is associated with the presence of diabetic nephropathy (Schalkwijk et al., 1999a). The fact that the actions of E-Hb are mainly mediated by ROS could be in accordance with a central role for oxidative stress in the development of diabetic vasculopathy (Tesfamariam, 1994; Giugliano et al., 1996; Spitaker and Graier, 2002) and would point at E-Hb as a source of such oxidative stress in diabetic vessels. www.nature.com /bjp/journal/v140/n4/full/0705483a.html   (6198 words)

Pets with Diabetes: Fructosamine and glycosylated Hemoglobin Glycosylated Hb and fructosamine levels have been studied in diabetic cats and dogs, and they have been shown to correlate with the severity of hyperglycemia. Elevated glycosylated Hb or fructosamine values reflect poor glucose control and indicate the need for a change in insulin therapy. Also, a "normal" glycosylated Hb or fructosamine test result can be obtained from an animal where the bg fluctuates between high and low values. www.petdiabetes.org /fructosamine.htm   (573 words)

ScienceDaily: Scientists At Scripps Research Describe New Strategy For The Synthesis Of Glycoproteins   (Site not responding. Last check: 2007-09-06) Methods for making glycosylated proteins are important to scientists who want to understand the role of carbohydrates in protein structure and function, since the human body contains many heavily glycosylated proteins, including antibodies, hormones, and immune system proteins like cytokines and interleukins. Even when it is possible to directly synthesize particular glycosylated proteins in the test tube, producing them may be expensive, difficult, time-consuming, and not at all practical. Some glycosylated proteins are produced in microorganisms or cultures of eukaryotic cells, like yeast or Chinese hamster cells­-an expensive and sometimes inexact process, which often involves difficult and expensive purification schemes. www.sciencedaily.com /releases/2004/01/040116080704.htm   (2743 words)

Last check: 2007-09-06) Many of the compounds used in drug discovery by pharmaceutical companies are glycosylated, bacterial secondary metabolites. A glycosylated metabolite consists of a central core structure (aglycon) and various sugar (glycosyl) attachments. Because the sugar moieties of many of these metabolites define their biological activities, altering the carbohydrate ligands can lead to valuable new pharmaceuticals; however, current methods of generating novel glycosylated metabolites for testing as drug candidates have severe limitations. www.warf.org /technologies.jsp?techfield=Chemical&msnum=242&casecode=P04020US   (379 words)
