Opis:
InWO3 -TiO2 nanocomposite material was synthesised by co-precipitation method and sonication technique. The synthesized nanomaterial was characterized by FE-SEM with EDX, HR-TEM, XRD, FT-RAMAN, AFM and BET surface area measurements. The photocatalytic activity of InWO3-TiO2 nanocomposite material was studied from the photodegradation of malachite green (MAG) under UV-light irradiation. The photodegradation of MAG at various parameters are reported. The Photodegradation was found to follow the pseudo-first-order kinetics. The Hydroxyl radical formation in the mechanism was confirmed by fluorescence quenching technique. The antimicrobial activity of the prepared nanomaterials has also been investigated. Cyclic voltammeter (CV)) measurements analysis of the prepared nonamaterial was discussed in detail. It was proposed that the catalyst was found to be stable and reusable.

Opis:
On the basis of our earlier studies in the group of 7,8-disubstituted derivatives of 1,3-dimetyl-3,7-dihydro-purine-2,6-dione, some new derivatives of theophylline were synthesized and tested for their electrocardiographic, antiarrhythmic and hypotensive activity as well as for α1-adrenoreceptor affinities. The performed preliminary tests indicated that new compounds did not significantly affect the normal ECG in vivo. As the result of present studies it may be concluded that all compounds did not possess hypotensive and arrhythmic activity. The results of the binding assays on α1-adrenergic receptors showed, that these derivatives display no affinity for α1-adrenergic receptors. Lack of antiarrhythmic and antihypertensive activity may result from the absence of affinity for the α1-adrenergic receptor. Performed chemical modifications lead to the loss of pharmacological activity previously observed among other derivatives in this group. Generally in comparison with the previously reported derivatives, replacing the phenoxyethylpiperazine by other moiety, changed the antiarrhythmic and hypotensive activity.

Opis:
The higher fungi are a rich source of chemical compounds with multi-directional therapeutic and pro-health effects. This review summarizes the results of the most important chemical and biological studies of the fruiting bodies and the mycelial cultures of Laetiporus sulphureus. Numerous studies have demonstrated the antimicrobial, anticancer, cytotoxic, hypoglycemic anti-inflammatory and antioxidant activity of the extracts. Currently, only a few wood-decay fungi have practical use in medicine. Therefore it seems important to continue research on the effectiveness and safety of extracts and compounds of natural origin, including fungi, whose potential is not still used.

Introduction: The progressive nature of multiple sclerosis (MS) is associated with numerous neurological deficits, leading gradually to deteriorating health and to disability. Purpose: The aim of this study was a subjective assessment of the physical and occupational activity of individuals with MS depending on the clinical form of the disease. Materials and methods: We used the original to conduct the research, with 28 closed questions. The study was carried out from December 1, 2018, to January 31, 2019, following approval by the Bioethics Committee of the Medical University of Bialystok, among persons belonging to the Association for Helping Sick People for Multiple Sclerosis in Białystok and patients of the Neurology Department of the University Clinical Hospital in Bialystok. The study sample comprised 50 people diagnosed with MS, 41 women and 9 men. Results: The most frequently occurring clinical form of MS was relapsing-remitting (68%). In this form, most participants had good physical fitness (44%). In those with the progressive-recurrent form (50%), very poor physical fitness was subjectively noted. Of those with the relapsing-remitting type of MS, 50% were professionally active, while none of the participants with the progressive-recurrent form were. Both the physical and occupational activities of MS patients were frequently limited by fatigue, balance disturbances, and movement difficulties. Fatigue was the most common symptom for most individuals with MS (82%). Conclusion: MS has a significant impact on both the physical activity and occupational functioning of patients. In the clinical form of MS, relapsing-remitting, patients’ physical fitness was better.

Opis:
Mobile health applications provide individuals with a mobile tool that can be tailored to meet various health needs and physical activity goals, which is particularly important during the Covid-19 pandemic and the associated social distancing protocols. The consequence that the pandemic has on the mental health of university students has prompted and increased the demand of physical activity interventions. The aim of this study was to determine the self-perceived effects of mobile health applications on physical activity participation among university students. Participants included students registered in one of the faculties at a university in Johannesburg. Data collection took place by means of an electronic questionnaire using Google Forms as a platform, completed by a sample of 192 students. The findings in the study reflected that majority of university students use health applications to increase physical activity levels or to track current activity levels. Participants also indicated that specific health applications were used to set goals, monitor progress and receive feedback. Aerobic activities proved to be the more popular type of physical activity in comparison to anaerobic activity. This study concluded that health applications can be used as a tool to facilitate and promote physical activity participation in the university student population.

Purpose: The aim of the presented study was the comparison of physical activity of students from selected countries. The key of paper selection was to find various kinds of students groups from different countries and different cultures. The author compared results of students’ physical activity.Materials and methods: The paper compare the previously published papers aboutphysical activity of students from selected countries. All respondents were examined using as an instrument the International Physical Activity Questionnaire (IPAQ), a standardized questionnaire which enables the investigation and comparison of activity of various population groups.Results: Analysis of results of the study showed a great differentiation among students from individual countries. In each examined group of students, males proved to be the most active gender; however, among countries characterized by the highest physical activity, the results obtained by females were sometimes higher than those concerning males from countries characterized by lower activity. The study showed that the most active students are Americans and Czechs, whereas students from Croatia and South Africa show low physical activity.Conclusions: The conducted analyses demonstrated that in each country in the study the level of total activity is higher among males than females. The differences in the results of the summary MET value in males remained within the range 2,800 – 6,500 MET, while in females - within the range 1,700 – 5,900 MET. Male students were usually characterized by a high level of physical activity, whereas female students by a moderate level. Among Polish students, similar to their contemporaries from other countries, the level of total physical activity was higher among males than females. Polish students were most often characterized by a moderate level of physical activity.

Opis:
This study is specifically concerned with the effect of regular physical activity during menstruation on the course of menstrual cycle among nullipara. Based on the author’s questionnaire, the 152 women participating in the study were divided into three groups A, B and C – depending on their level of physical activity. The physical activity at a moderate level does not significantly affect the regularity of menstrual cycles. The cultivation of moderate physical activity during menstruation does not significantly affect the duration of bleeding. Moderate physical activity is irrelevant to the abundance of menstrual bleeding. Moderate physical activity has no significant effect on menstrual pain and its duration. Women who are physically active at a moderate level throughout their menstrual cycle are less likely to experience symptoms of premenstrual syndrome (PMS) than women who are only physically active outside of menstruation and are not physically active, which may indicate that moderate physical activity during menstruation prevents symptoms of premenstrual tension syndrome. Based on the results achieved, it is not possible to clearly determine the relevance of promoting moderate physical activity, with particular emphasis on that during menstruation, among women. The study needs to be continued with particular attention paid to physical activity during the day, the influence of environmental factors and stress on the examined women, and with attention paid to the intensity of pain accompanying bleeding. However, it can be assumed that there is no justification for limiting physical activity during the menstrual bleeding phase.

Introduction. Research on the literature shows different and sometimes contradictory data about the physical activities of women and men. Aim. The goal of the research study is to compare selected aspects of physical activity in women and men. Material and methods. 100 men and 100 women were selected and tested using the “pairing method” and examined in terms of four variables: place of residence, education, marital status and age. A specially prepared survey questionnaire was used. Results. Men and women differ in terms of certain aspects of physical activity (especially its types), while their motivations and limitations only slightly differ. Conclusions. Women significantly more often prefer walking as a physical activity, while men prefer running, swimming, and using the weight room and gym for team sports. On working days, women have significantly less free time than men. The only motivating factor for physical activity that differentiates both groups is the “beauty” motif that is more often present in women. The groups do not differ in terms of obstacles keeping them from undertaking physical activity, although women more often reported a lack of time.
