The role of platelets in hemostasis and thrombosis is clearly established; however, the mechanisms by which platelets mediate inflammatory and immune pathways are less well understood. Platelets interact and modulate the function of blood and vascular cells by releasing bioactive molecules. Although the platelet is anucleate, it contains transcripts that may mirror disease. Platelet mRNA is onl...

Diabetic and sickle retinopathy have features in common--for example, venous dilatation, microaneurysms, and capillary closure preceding neovascularisation. Bearing in mind that haemoglobin in poorly controlled diabetes is abnormal and that extremely low oxygen tensions (known to cause sickling) exist in the healthy cat retina, we wished to explore the possibility that diabetic blood, like that...

Resumen.—La molécula de hemoglobina juega un papel clave en el transporte de oxígeno. Hemoglobinas con gran afinidad por el oxígeno son adaptativas en ambientes hipóxicos. Para ampliar nuestro conocimiento acerca de la adaptación a la hipoxia de altura, se extrajo ARN de la médula ósea de seis espécimenes de Lophonetta specularioides de los Andes centrales de Perú (4218–4605 m) y se secuenciaro...

PURPOSE This meta-analysis was conducted to assess the effect of educational and behavioral interventions on body weight and glycemic control in type 2 diabetes. METHODS Studies selected for analysis were published randomized controlled trials that evaluated educational and behavioral interventions (no drug interventions) in type 2 diabetes (sample size > or = 10). These criteria were applied...

AIM To assess aortic and carotid intima-media thickness (aIMT and cIMT) in diabetic patients. PATIENTS AND METHODS The study included 75 type 1 diabetic patients and 30 age and sex matched healthy volunteer. A blood sample was taken for analysis of HbA1 and lipid profile and the urine sample was taken for analysis of albumin/creatinine ratio. aIMT and cIMT via ultrasound were also done. RES...

More than 1000 herbal products have been used by diverse cultures of the world to treat hyperglycemia and among them bitter melon (Momordica charantia) is one of the most popular herbal resource. The beneficial effects of bitter melon is not limited to hypoglycaemia only, but it also ameliorates diet induced obesity, insulin resistance and exhibit cardioprotective effects. The present study att...

BACKGROUND During medical checkups of two unrelated female outpatients during their annual health examination and one male inpatient suffering from cardiac failure the glycated haemoglobin (HbA1C) concentrations measured by high performance liquid chromatography (HPLC) were low, in spite of normal fasting plasma glucose concentrations. However, HbA1C concentrations measured by latex immunoagglu...

Growth hormone (GH) responses to growth-hormone-releasing hormone (GRH) and thyrotropin-releasing hormone (TRH) were studied in 17 diabetic patients. Ten patients (group 1) had retinopathy corresponding to stage III-V (Scott's classification), and the remaining seven patients (group 2) had no retinopathy despite longer duration of diabetes in comparison with the patients in group 1. There were ...

To identify the antidiabetic plants of Iran, a systematic review of the published literature on the efficacy of Iranian medicinal plant for glucose control in patients with type 2 diabetes mellitus was conducted. We performed an electronic literature search of MEDLINE, Science Direct, Scopus, Proquest, Ebsco, Googlescholar, SID, Cochrane Library Database, from 1966 up to June 2010. The search t...

On 398 river buffalo samples, randomly collected in distinct breeding areas of the Campania region, high-resolution analytical systems were used to identify both qualitative and quantitative variations of the Hb phenotype. Polyacrylamide gel isoelectric focusing and HPLC were used to determine the ratio between HBA1 and HBA2 globin chains; restriction endonuclease analysis was performed to asse...
