the zagros forests (west of iran) have been highly exploited in recent decades by human impacts. easy access, abundance and variety of valuable forest yields have led to population growth density, creation of new residential areas and deforestation activities. in order to determinate the distribution and rate of deforestation from 1995 to 2006 by using the satellite imagery (irs-1c and  landsat...

background: diabetic patients have some difficulties in controlling their disease and integrating it in their life. self-efficacy is a psychosocial variable in the field of diabetes which can have desirable or undesirable effects on all kinds of disease outcomes. this study aimed to determine self-efficacy and its effective factors among type 2 diabetic patients. methods: this cross-sectional s...

OBJECTIVE Current recommendations for the use of hemoglobin A(1c) (HbA(1c)) in diabetes screening and diagnosis aim to identify those at greatest risk for diabetic microvascular complications. However, there is current controversy regarding the clinical implications of ethnic differences in HbA(1c) values. The objective of this study was to determine whether the association between HbA(1c) and ...

In the present study, we aimed to decipher the mechanisms involved in the transcriptional effect of insulin on the SREBP-1c specific promoter of the human srebf-1 gene. Using luciferase reporter gene constructs in HEK-293 cells (human embryonic kidney cells), we demonstrated that the full effect of insulin requires the presence of SREs (sterol response elements) in the proximal region of the pr...

BACKGROUND The evidence for an association between insomnia symptoms and blood hemoglobin A(1c) (HbA(1c)) level has been limited and inconclusive. The aim of this study was to assess whether each symptom of initial, middle, and terminal insomnia influences HbA(1c) level in Japanese men. METHODS This cross-sectional study examined 1,022 male workers aged 22-69 years with no history of diabetes...

OBJECTIVE Recent evidence suggests that poor glycemic control is significantly associated with the development of macrovascular complications of diabetes. Studies have indicated that C-reactive protein (CRP) is an important risk factor for cardiovascular disease. The purpose of this study was to determine the relation between CRP and HbA(1c) in a large national sample of individuals with diabet...

OBJECTIVE Hemoglobin A1c (HbA(1c)) has been widely used as a clinically important assessment tool for outcome analyses related to glycemic control. However, because of special conditions in dialysis patients, including the uremic milieu, there is no HbA(1c) blood glucose (BG) equation specific for patients on dialysis. In this study, we sought to develop HbA(1c)-BG equation models for hemodialy...

OBJECTIVE To describe the distribution of HbA(1c) levels among children and young adults in the U.S. and to evaluate the effects of age, sex, race/ethnicity, socioeconomic status, parental history of diabetes, overweight, and serum glucose on HbA(1c) levels. RESEARCH DESIGN AND METHODS We analyzed HbA(1c) data from the Third National Health and Nutrition Examination Survey, 1988-1994, for 7,9...

OBJECTIVE To assess the pattern of glycosylated hemoglobin (HbA(1c)) requests by clinicians from eight health departments by calculating indicators of demand appropriateness. METHODS A cross-sectional study of the number of HbA(1c) requests by primary care clinics in 2008 and 2009. The indicator of demand appropriateness was the proportion of HbA(1c) values lower than 6.5%. Variables were col...
