This study was carried out to determine whether a short-term zinc supplementation contributes to beneficial changes in glycemic control among type 2 diabetic patients. Seventy-six diabetic subjects and 72 normal adults participated in this study. Subjects were divided into supplemented and control groups. Forty-four diabetic patients and 34 normal subjects were supplemented with 50 mg zinc dail...

BACKGROUND The relationship between glycated haemoglobin and the incidence of end-stage renal disease (ESRD) in patients with diabetes remains uncertain, especially in those with decreased glomerular filtration rate (GFR). The aim of this study was to assess the appropriate HbA(1c) level for diabetics for minimizing the incidence of ESRD and all-cause mortality. METHODS A cohort of patients a...

AIMS Using the HbA(1c) level to define diabetes has several advantages and these advantages also apply to define a high-risk group. However, the risk of diabetes increases as HbA(1c) increases and a certain degree of arbitrariness in the cut-off for the high risk group is unavoidable. The aim of this study was to determine the HbA(1c) cut-off for defining a high-risk group that corresponds to t...

OBJECTIVE To compare the abilities and associated hypoglycemia risks of insulin glargine and human NPH insulin added to oral therapy of type 2 diabetes to achieve 7% HbA(1c). RESEARCH DESIGN AND METHODS In a randomized, open-label, parallel, 24-week multicenter trial, 756 overweight men and women with inadequate glycemic control (HbA(1c) >7.5%) on one or two oral agents continued prestudy ora...

We hypothesized that school nurse supervision of glucose and insulin-dose adjustment significantly improves the hemoglobinA(1c) (HbA(1c)) level in pediatric patients with poorly controlled type 1 diabetes mellitus (HbA(1c) > or = 9%). A total of 36 subjects were enrolled and 18 subjects were randomized to receive the 3-month intervention. Their average HbA(1c) was lowered by 1.6%, suggesting th...

Charged amino acids in the predicted transmembrane portion of PcaK, a permease from Pseudomonas putida that transports 4-hydroxybenzoate (4-HBA), were required for 4-HBA transport, and they were also required for P. putida to have a chemotactic response to 4-HBA. An essential amino acid motif (DGXD) containing aspartate residues is located in the first transmembrane segment of PcaK and is conse...

Liberal fluid intake is one of the key management strategies in sickle cell anaemia [SCA] patients in steady state, but less work has been done on the desire of patients to drink water. Using the Visual Analogue Scale we studied thirst perception [TP] in 20 euhydrated SCA patients and 28 control [HbA] subjects, as well as during dehydration in 13 SCA patients and 9 HbA subjects. Serum and urine...

The association of chronic glycemia, measured by HbA(1c), with long-term complications of type 1 diabetes has been well established in the Diabetes Control and Complications Trial (DCCT) and other studies. The role of intermediate-term and acute glycemia and of glucose variability on microvascular and cardiovascular disease (CVD) is less clear. In order to examine the interrelationships among l...

OBJECTIVE HbA(1c) levels are higher in most ethnic groups compared with white Europeans (WEs) independent of glycemic control. This comparison has not been performed between South Asians (SAs) and WEs. We analyzed the independent effect of ethnicity on HbA(1c) and fasting and 2-h plasma glucose (FPG and 2 hrPG, respectively) between these groups. RESEARCH DESIGN AND METHODS Analysis of the AD...

Increased fructose concentration in diabetes mellitus causes fructation of several proteins. Here we have studied fructose-induced modifications of hemoglobin. We have demonstrated structural changes in fructose-modified hemoglobin (Fr-Hb) by enhanced fluorescence emission with excitation at 285 nm, more surface accessible tryptophan residues by using acrylamide, changes in secondary and tertia...
