Comparison of Methods for Measuring Protein Concentration in Venom Samples.

Snake venom is an extremely interesting natural mixture of proteins and peptides, characterized by both high diversity and high pharmacological potential. Much attention has been paid to the study of venom composition of different species and also detailed analysis of the properties of individual components. Since proteins and peptides are the active ingredients in venom, rapidly developing proteomic techniques are used to analyze them.

Polyethylene microplastics influence the transport of organic contaminants in soil.

Plastics are now found in all natural environments including soil. The effects of microplastics in terrestrial systems, however, remain largely unexplored. Polyethylene is one of the mass-manufactured polymers found in terrestrial environments.

Late subclinical hemolysis and long-term outcomes after aortic valve replacement with On-X mechanical prostheses - a preliminary single-center report.

Introduction: Aortic valve replacement (AVR) with a mechanical prosthesis is not free from late complications.

Aim: To evaluate the prevalence of subclinical hemolysis after AVR with On-X prostheses and assess its impact on long-term outcomes.

Material And Methods: The prospective study included 84 consecutive patients aged 58.

Red Blood Cells Distribution Width as a Potential Prognostic Biomarker in Patients With Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension.

Background: Red blood cells distribution width (RDW) predicts survival in cardiovascular diseases. Little is known about the variability of RDW level over time among patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). To our knowledge, RDW has never been analysed as a marker of response to specific treatment.

Interventional closure of patent foramen ovale with Nit-occlud® device in prevention of recurrent neurologic events-Long-term results.

Background: Patent foramen ovale (PFO) was found to be associated with the increased risk of recurrent strokes or transient ischemic attacks (TIA) and there is a need of secondary prevention. Numerous devices have been developed and used for treatment.

Objectives: The aim of the study was to evaluate the safety and effectiveness of a new PFO occluder Nit-Occlud PFO Occlusion Device (PFM medical, Germany).
