Postural stability in athletes: The role of sport direction.

Background: The bulk of relevant studies compare individual or very few sports and on small samples of athletes. This requires extensive analysing postural stability in various sports.

Research Question: The main objective of our study was to identify the features of postural stability in a normal vertical stance in athletes of various kinds.

Postural Stability in Athletes: The Role of Age, Sex, Performance Level, and Athlete Shoe Features.

The effects of different factors-such as age, sex, performance level, and athletic shoe features-on postural balance in athletes remain unclear. The main objective of our study is to identify the features of postural stability in athletes of different age, sex, performance level, and using different types of athletic shoes. This study assessed postural stability in athletes ( = 936, 6-47 years) in a normal bipedal stance with eyes open (EO) and eyes closed (EC).

[Does an attempt to save a limb always prolong the patient's life?].

Aim: The purpose of the study was to examine overall survival and the incidence of major adverse cardiovascular events, as well as economic expenditures for treatment of patients with occlusion of the femoropopliteal-tibial segment and critical ischaemia in low competence of the outflow channel, with a poor prognosis for endovascular or open revascularization of lower-limb arteries.

Patients And Methods: We studied the results of treating a total of 68 patients with lower-limb critical ischaemia and low parameters of the outflow channel competence. Primary arterial reconstruction was performed in 48 cases.

[Antithrombotic therapy after bypass grafting below the inguinal ligament].

The importance of antithrombotic therapy following reconstructive operations on arteries below the inguinal ligament is beyond question. The pharmaceutical market offers a wide variety of antiaggregant and anticoagulant agents, with many studies (including randomised and multicenter ones) performed worldwide on the problem of choosing optimal antithrombotic therapy in the postoperative period after arterial reconstructions. Nevertheless, the problem of selecting adequate antithrombotic therapy after shunting operations remains undetermined.

Fabrication and properties of luminescence polymer composites with erbium/ytterbium oxides and gold nanoparticles.

Rare-earth-doped optical materials are important for light sources in optoelectronics, as well as for efficient optical amplification elements and other elements of photonics. On the basis of the previously developed method of anhydrous, low-temperature synthesis of Er/Yb oxides from their chlorides we fabricated proper nanoparticles with defined parameters and used them for the development of optically transparent, luminescent polymer nanocomposite with low optical scattering, suitable for direct, light-induced formation of photonic elements. Introduction of preformed gold nanoparticles in such a nanocomposite was also performed and an enhancement of luminescence due to the influence of plasmon effects was detected.
