Seasonal dynamics of myocardial infarctions in regions with different types of a climate: a meta-analysis.

Background: It is known that cardiovascular events (CVE) occur more often in winter than in summer. However, dependence of myocardial infarction (MI) risk of on various meteorological factors is still not fully understood. Also, the dependence of the seasonal dynamics of MI on gender and age has not yet been studied.

Effects of ischaemic postconditioning in aortic valve replacement: a multicenter randomized controlled trial.

Objectives: The effect of ischaemic postconditioning (IPost) on postcardioplegic cardiac function is not known. We hypothesized that IPost was cardioprotective in adult patients undergoing elective aortic valve replacement.

Methods: In a multicentre, prospective, randomized trial, patients (n = 209) were randomized to either a standard operation (controls) or postconditioning.

Neurohumoral, cardiac and inflammatory markers in the evaluation of heart failure severity and progression.

Heart failure is common in adult population, accounting for substantial morbidity and mortality worldwide. The main risk factors for heart failure are coronary artery disease, hypertension, obesity, diabetes mellitus, chronic pulmonary diseases, family history of cardiovascular diseases, cardiotoxic therapy. The main factor associated with poor outcome of these patients is constant progression of heart failure.

Time- and Ventricular-Specific Expression Profiles of Genes Encoding Z-Disk Proteins in Pressure Overload Model of Left Ventricular Hypertrophy.

Mechanotransduction is an essential mechanism of transforming external mechanical stimulus to biochemical response. In cardiomyocytes mechanotransduction plays an important role in contraction, stretch sensing and homeostasis regulation. One of the major mechanosensitive area in cardiomyocytes, the Z-disk, consists of numbers of structural and signaling proteins, that may undergo conformational or gene expression changes under pathological stress conditions.

Autotransplantation of cryopreserved ovarian tissue--effective method of fertility preservation in cancer patients.

Objective: To review the literature and to present the latest advances in the autotransplantation of cryopreserved ovarian tissue.

Materials And Methods: A literature review was conducted for all relevant articles assessing the fertility preservation, ovarian tissue transplantation, standard freezing and vitrification of ovarian tissue.

Results: One of the promising and effective methods for fertility preservation may be the autotransplantation of cryopreserved ovarian tissue.
