Performance of IS6110-LAMP assay for detection of Mycobacterium tuberculosis complex in blood and urine samples from patients with extrapulmonary tuberculosis.

Background: The diagnosis of extrapulmonary tuberculosis (EPTB) shows numerous difficulties because of non-specific symptomatology and low sensitivity of conventional methods. Loop-mediated isothermal amplification (LAMP) is a fast and low-cost technique, which can amplify under isothermal conditions an amount of target DNA copies into approximately a billion copies.

Objective: The present study aimed to evaluate a IS6110-LAMP system for Mycobacterium tuberculosis detection in blood and urine samples from patients with EPTB.

Evaluation of the influence of global DNA methylation level in patients with acute coronary syndrome.

DNA methylation is one of the mechanisms of epigenetic regulation and is observed in mammals to maintain a normal expression pattern of the genes. Aberrant profiles of DNA methylation have already been associated with cardiovascular diseases. We evaluated 190 patients with Acute Coronary Syndrome (ACS) and 75 patients without ACS (non-ACS).

Acute coronary syndrome: Relationship between genetic variants and TIMI risk.

Acute Coronary Syndrome (ACS) is a multifactorial disease, including the genetic factor, caused by coronary artery obstruction by atheroma. Some genetic variants have been described as risk factors for this disease. Its early diagnosis and stratification of risk of death by Thrombolysis in Myocardial Infarction (TIMI) are important.
