Left ventricular longitudinal strain and strain rate measurements in paediatric patients in long-term treatment for Chagas disease.

Introduction: Previous echocardiographic studies failed to show residual alterations of heart function in paediatric patients that have received treatment for Chagas disease. While the echocardiogram is the fundamental front-line tool for evaluating heart function, the appearance of new techniques allows a more detailed analysis. We aimed to evaluate systolic and diastolic function with new techniques in a paediatric population with Chagas disease several years after treatment completion.

[Immunizations in adults with cardiovascular disease. Summary of the Consensus of the Argentine Cardiology Society].

Cardiovascular diseases are the leading cause of death in most regions of the world, usually followed by infectious diseases. For decades, infections in general, and particularly those involving the respiratory system, have been known to be associated with an increased risk of cardiovascular and cerebrovascular events, and their consequent morbidity and mortality. Although vaccines are an excellent strategy in the prevention of infectious diseases, the proportion of immunized adults in our country is frankly deficient.

Four glycoproteins are expressed in the cat zona pellucida.

The mammalian oocyte is surrounded by a matrix called the zona pellucida (ZP). This envelope participates in processes such as acrosome reaction induction, sperm binding and may be involved in speciation. In cat (Felis catus), this matrix is composed of at least three glycoproteins called ZP2, ZP3, and ZP4.

Rabbit zona pellucida composition: a molecular, proteomic and phylogenetic approach.

The zona pellucida (ZP) participates in sperm-egg interactions during the first steps of fertilization. Recent studies have shown that the ZP matrix of oocytes in several species is composed of four glycoproteins, designated as ZP1, ZP2, ZP3 and ZP4, rather than the three described in mouse, pig and cow. In this study, investigations were carried out to unveil a fourth glycoprotein in the rabbit (Oryctolagus cuniculus) ZP.

Partial humeral head resurfacing and Latarjet coracoid transfer for treatment of recurrent anterior glenohumeral instability.

Bone deficiencies of either the humeral head or glenoid fossa may cause recurrent shoulder instability following soft tissue stabilization procedures. The engaging Hill-Sachs lesion, a major risk factor for instability, has been identified in a majority of patients with recurrent anterior instability. Guidance for surgical management of large humeral head deficiency presents few available options, with even fewer clinical data to support any one technique.
