Sepsis induced by cecal ligation and perforation (CLP) alters nucleotidase activities in platelets of rats.

Sepsis is a potentially lethal condition, and it is associated with platelet alterations. The present study sought to investigate the activity of ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase), E-5'-nucleotidase, and ecto-adenosine deaminase (E-ADA) in the platelets of rats that were induced with sepsis. Male Wistar rats were divided into three groups of ten animals each: a negative control group (normal; NC); a group that underwent surgical procedures (sham); and a group that underwent cecal ligation and perforation (CLP).

Hba(1c) as a tool for the diagnosis of type 2 diabetes: comparison with fasting glucose.

Background: Glycated hemoglobin (HbA(1c)) has been proposed for the diagnosis of diabetes. However, several countries have not incorporated its use for this purpose yet and there is no consensus on a suitable cut-off point of HbA(1c) for the diagnosis of diabetes. Thus, the aim of this study was to evaluate the diagnostic characteristics of HbA(1c) and fasting plasma glucose (FPG) for the assessment of type 2 diabetes.

Effect of temperature on albumin cobalt binding and its influence on ischemia-modified albumin levels in patients with suspected acute coronary syndrome.

Background: Ischemia-modified albumin (IMA) has been shown to be a rapidly rising and sensitive biochemical marker especially for the diagnosis of myocardial ischemia. The aim of this study was to evaluate the influence of temperature on the capacity of cobalt binding to human albumin and the influence of this variable on IMA measurement.

Methods: The following temperatures of incubation were tested for human albumin standard 25 degrees C, 28 degrees C, 31 degrees C, 34 degrees C, and 37 degrees C and for patients with suspected acute coronary syndrome, room temperature and 37 degrees C.
