Successful Young Athletes Have Low Probability of Being Ranked Among the Best Senior Athletes, but This Is Higher When Compared to Their Less Successful Peers.

Background: Contemporary research has shown that only a small proportion of high achieving young athletes continue to become successful senior athletes. However, there is a lack of empirical literature tracking the success of senior male and female athletes who were considered high achieving as a youth.

Hypothesis: Athletes of both sexes who are successful in youth categories (U18 and U20) are more likely to be successful senior athletes.

Nordic Walking as an effective physical activity for weight loss among overweight young adults in high schools.

Background: Overweight and obesity, low physical activity and lack of motivation to exercise are common among young adults. Thus, the objective of the study is to evaluate the efficiency of Nordic Walking for weight loss and improvement of functional and physiological state in young adults with overweight and obesity.

Methods: The study enrolled 77 students from Sechenov University with overweight and obesity aged from 17 to 23 years.

Effect of Physical Rehabilitation on Echocardiographic Parameters in Patients with Acute Coronary Syndrome.

Echocardiographic parameters were assessed in patients with non-ST segment elevation acute coronary syndrome, who underwent emergency percutaneous coronary intervention followed by various outpatient physical cardiac rehabilitation programs. The patients underwent physical rehabilitation for 3 months under conditions of diagnostic centre in the rehabilitation unit according to the standard program including in treadmill or bicycle exercise in the exercise therapy room or with Nordic walking in the main training block. After rehabilitation course, the left ventricular mass index significantly decreased and systolic volume and left ventricular ejection fraction significantly increased in both groups.

Alumina nanoparticle-assisted enzyme refolding: A versatile methodology for proteins renaturation.

We present a high-yield method for the renaturation of negatively charged enzymes. The approach is based on the use of alumina nanoparticles, which after electrostatic interaction with denatured protein molecules, prevent their aggregation and make the process of refolding controllable. The method, demonstrated by the renaturation of several enzymes, is efficient, rapid, employs a minimal amount of reagents and even can be applied to renature mixture of the denatured enzymes.
