[Erectile dysfunction in railway station workers: principles of treatment (prospective randomized study)].

Introduction: Erectile dysfunction is often a consequence of stressful situations, lack of adequate sleep and rest, and sedentary lifestyles. The profession of locomotive engineer implies the presence of these negative factors, which in addition provoke high blood pressure and the development of hypertension.

Materials And Methods: A total of 85 patients of the urological and therapeutic departments of the "Clinical Hospital "Russian Railways Medicine" in the city of Barnaul", working as locomotive drivers or assistant drivers, were examined.

The Improved Biometric Identification of Keystroke Dynamics Based on Deep Learning Approaches.

In an era marked by escalating concerns about digital security, biometric identification methods have gained paramount importance. Despite the increasing adoption of biometric techniques, keystroke dynamics analysis remains a less explored yet promising avenue. This study highlights the untapped potential of keystroke dynamics, emphasizing its non-intrusive nature and distinctiveness.

Lithium-Modified Sorbent: Effects on Hemostatic Responses In Vitro.

The effects of a lithium-modified sorbent based on aluminum oxide and polydimethylsiloxane (AlO@PDMS/Li) and a lithium-free sorbent (AlO@PDMS) on some indicators characterizing blood clotting under hemosorption conditions were compared in vitro. Sorbent AlO@PDMS/Li had significantly lower reactogenic effect on the blood passed through the column than the sorbent without lithium. This was seen from the degree of platelet reduction (66×10 vs 19×10/liter) as well as a less pronounced hypercoagulation shift in chronometric indicators.

Screening of the Promising Direct Thrombin Inhibitors from Haematophagous Organisms. Part I: Recombinant Analogues and Their Antithrombotic Activity In Vitro.

The success in treatment of venous thromboembolism and acute coronary syndromes using direct thrombin inhibitors has stimulated research aimed at finding a new anticoagulant from haematophagous organisms. This study deals with the comparison between hirudin-1 from (desirudin), being the first-known and most well-studied natural anticoagulant, along with recombinant analogs of haemadin from the leech , variegin from the tick , and anophelin from . These polypeptides were chosen due to their high specificity and affinity for thrombin, as well as their distinctive inhibitory mechanisms.

Pregnancy complications in G20210A mutation carriers associated with high prothrombin activity.

Objective: To study the association between high activity of Factor II (prothrombin) in blood plasma with G20210A mutation and the development of great obstetrical syndromes.

Material And Methods: A prospective clinical cohort study was conducted on 290 pregnant women (average age 31.7 ± 4.
