Objective: To analyze three functional vascular endothelial growth factor (VEGF) polymorphisms (-460C/T, +405G/C, and 936C/T) in women with and without endometriosis and their correlation with VEGF expression in endometrial tissue and peritoneal fluid (PF).

Design: Case-control study.

Setting: University-based hospital.

The fibrinolytic system includes a broad spectrum of proteolytic enzymes with physiological and pathophysiological functions in several processes, such as haemostatic balance, tissue remodeling, tumor invasion, angiogenesis and reproduction. The main enzyme of the plasminogen activator system is plasmin, which is responsible for the degradation of fibrin into soluble degradation products. The activation of plasminogen into plasmin is mediated by two types of activators, urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA).

Introduction: Endometriosis is a benign gynecologic disease with a high prevalence. It is a multifactorial and polygenic entity in which the fibrinolytic system may be implicated. The objective of this study was to evaluate the plasminogen activator inhibitor-1 (PAI-1) 4G/5G polymorphism in a group of women with and without endometriosis and to analyze the influence of this polymorphism in PAI-1 expression in endometrial tissue and peritoneal fluid.

Sequences from the ribosomal nuclear internal transcribed spacers (ITS) have been widely used to infer evolutionary hypotheses across a broad range of living organisms. Intraspecific sequence variation is assumed to be absent or negliable in most species, but few detailed studies have been conducted to assess the apportionment of ITS sequence variation within and between plant populations. Buxus balearica was chosen as a model species to assess the levels of infraspecific and intragenomic ITS variation in rare and endangered species occurring in disjunct populations around the Mediterranean basin.
