Physico-Chemical Properties of Nanoparticles Functionalized by Polypyrrole

Мagnetite nanoparticles coated with polypyrrole have been synthesized. Nanocomposite powder has been investigated by FTIR, XRD, SEM, magnetometry, conductivity measurements. Polypyrrole in nanocomposite does not impair the magnetic properties of magnetite. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3366

Stimulation of Seed Viability by Means of Dispersed Solutions of Copper and Silver Nanoparticles

It was shown that water dispersed solutions at different concentration of copper (NPCu) and silver (NPAg) nanoparticles substantially influence germination of seeds of grain and vegetable crops. Stimulating effect was revealed after application of ultra-low concentrations NPCu (up to 10 – 17 mg/l) and NPAg (up to 10 – 13 mol/l). Treatment of seeds with sol boosts their resistance to fungal pathogens and low temperature and also increases productivity of plants in the field environment.

Synthesis and Identification of Zinc Oxide Nanoparticles as Precursor for Getting Zinc-Based Biologically Active Additives

Zinc oxide nanoparticles were synthesized in order to get biologically active additive for correction of zinc-deficiency states. Nanosized zinc oxide was derived by through condensation method from zinc acetate and lithium hydroxide dissolved in dehydrated alcohol. Resulted particles were examined through method of small-angle X-ray scattering. Measurement results confirm presence of nanoparticles with average size about 2 nm.

Development and Physico-chemical Study of the Aqueous Dispersion Silver Nanoparticles as the Basis for Creating New Nanomaterials

The aqueous dispersion of silver nanoparticles have been obtained and studied by physicochemical methods. Maximum of size nanoparticles distribution in the aqueous dispersion determined by the small angle X-ray scattering technique was 2.5 nm. The composition on the basis of those nanoparticles can be used to create new nanomaterials, in particular for the modification of talc silver nanoparticles. The existence of nanoparticles at the talс surface is corroborated by the data of energy dispersive spectra and by X-ray diffraction spectra

Efficiency of the «Valikar» drug on the example of one-offer athletes-wrestlers during the intensive training loads. Communication 4. Peculiarities of change anthropometric parameters and component body composition

In the fourth, final, report of a series of articles on the results of clinical testing of the anti-asthenic drug «Valikar» in 31 athletes-wrestlers under intense training loads, the results of the study of the dynamics of changes in parameters аntropometric and body composition parameters are presented. The study of the effect of 15-day course intake of the drug «Valikar» on the anthropometry and body composition parameters by the bioimpedance method. In general, the study sample of athletes showed high levels of active cell mass, moderate indicators of adipose tissue mass, as well as a balanced water content in the body. In the course of the study, during the course of the medication «Valikar» in both groups of the examined, there were no significant significant differences in the dynamics of indicators analysis. According to the results of anthropometric studies and bioimpedance analysis of body composition, no statistically significant differences were found between the group taking the drug and the group receiving placebo. In addition, the anabolic activityof the drug «Valikar» was not revealed, which is probably related to the dosage of the drug.В четвертом, заключительном, сообщении цикла статей по результатам клинической апробации противоастенического лекарственного средства «Валикар» у 31 спортсмена-единоборца в условиях интенсивных тренировочных нагрузок представлены результаты исследования динамики изменения антропометрических параметров и компонентного состава тела. Проведенное исследование влияния 15 дневного курсового приема лекарственного средства «Валикар» на параметры антропомоетрии и компонентного состава тела методом биоимпедансометрии. В целом в исследуемой выборке спортсменов отмечены высокие показатели активной клеточной массы, умеренные показатели массы жировой ткани, а также сбалансированное содержание воды в организме. В ходе исследования в процессе курсового приёма препарата «Валикар» в обеих группах обследованных достоверных значимых отличий в динамике показателей биоимпедансного анализа обнаружено не было. По результатам антропометрических исследований и биоимпедансного анализа компонентного состава тела не выявлено статистически значимых различий между группой, принимавшей ЛС, и группой, получавшей плацебо. Кроме того, не было выявлено и анаболической активности лекарственного средства «Валикар», что, вероятно, связано с дозировкой препарата
