Nonylphenol (NP), as a typical environmental endocrine disruptor, exists widely in the natural environment. It has a high toxicity with a low concentration. NP at the level of μg/L is enough to interfere with the sex differentiation of many aquatic organisms. The effects of degradation of NP in waste water by strong ionization (SID) and its degradation products on sex differentiation in zebrafish was studied in this paper. The NP solution of 5mg/L was degraded by SID device, and the 20d zebrafish were exposed to NP wastewater of different concentrations before and after degradation until their sexual maturity. The body length, body weight and sex differentiation ratio of zebrafish were recorded, and the sex hormone levels of zebrafish were extracted and detected. The gonadal glands of zebrafish were slices and analysed. This study found that the effects of nonylphenol on male zebrafish were much greater than that of female, and there was no significant positive correlation between toxicity and dose. In addition, the effects of 5mg/L NP wastewater degraded by SID for 60min were not significantly different from those of the control group, indicating that SID could effectively degrade NP and alleviate its biological toxicity.

BACKGROUND Balance training in young adults may increase coordination, cognitive function or the symmetry of strength on both sides of the body. It is an essential tool for injury or fall prevention and a precondition for becoming a professional athlete. OBJECTIVE The aim of this study was to assess the effect of Xbox 360 Kinect training on postural balance in young, healthy individuals. METHODS The study enrolled 75 individuals who were randomly assigned to three equal groups. The first group (Group VR) performed exercises on an Xbox 360 Kinect console, and the second group (Group T) performed conventional all-round exercises. The third group was a control group (Group C). Each group underwent balance assessments on the Biodex Balance posturographic platform, including the Balance Error Scoring System test, before and after the training cycle. The level of statistical significance was set at P<.05. RESULTS Group VR and Group T achieved statistically significant improvements in the sway index compared with baseline. Group T gained significant decrease in the sway index on the unstable surface (P=.002). Group VR and group T demonstrated significant decreases in the mean sway index on stable and unstable surfaces (group VR — P=.035; group T — P=.001) Group C did not achieve a statistically significant improvement in the sway index. None of the groups demonstrated a statistically significant decrease in the test error count. CONCLUSIONS Virtual reality in the form of video games played on an Xbox 360 Kinect console may be an effective method of balance training in healthy individuals.

Stress is an individual's adaptive response to various external pressures or demands and produces a variety of disorders including physical, emotional and behavioral disorders. Final year students often experience feelings of stress so that it can interfere with concentration to attend lectures and can even hamper completing education in a timely manner. There are several ways of managing stress, one of which is using aromatherapy. Aromatherapy is a non-pharmacological therapy, which is a type of therapy that applies direct body contact and has a therapeutic effect that combines physiological effects, caused by massage on the body, with psychological effects, which are derived from essential oils. The general purpose of the study is to analyze the effect of aromatherapy on blood pressure and stress levels by using the Kessler Psychological Distress Scale in final semester students. The research method used a quasi-experimental design with a pretest-posttest control group design approach, in 28 intervention groups, namely respondents who were given lavender aromatherapy massage and 28 respondents in the control group. The univariate analysis was conducted to show frequency distribution and bivariate analysis was conducted by independent sample T-test and dependent sample T-test. The results showed that there were significant differences in systolic blood pressure before and after the intervention in the intervention and the control group with a p-value of 0.01 < 0.05. Whereas the stress level variable found that there is no difference in stress levels in the intervention and the control group before and after the intervention with p-value 0.169> 0.05.

Pregnancy is a period of both hormonal and non-hormonal overall change in the body. Emotional instability is commonly experienced by women during this period. However, this somewhat complex issue is often not addressed optimally. Pharmacological therapies using CPZ and lithium are often administered, but they have effects for the body. Therefore, there is a need to administer non-pharmacological therapy that has minimum side effects. This research aims to increase the healthy energy within the body using Pranic Healing, which is measured by the Bio-Well GDV camera. This research employed the pretest-posttest method on two groups (treatment and control) using the Randomized Controlled Trial design. Pranic Healing therapy was performed for 30 minutes once a week for 3 weeks, while GDV measurement was performed once a week for 4 weeks. Paired t-test results for Pranic Healing on emotional pressure showed p-value of 0.0001 (<0.05) for posttest2 and p-value of 0.005 (<0.05) for posttest3. Meanwhile, the control group did not indicate any changes in emotional stress both before and after treatment. It is found that Pranic Healing as measured using a bio-well GDV camera is capable of improving health energy within the body by relieving emotional stress experienced in trimester III primigravida.

Subject. Removable dentures have a negative impact on supporting tissues, biochemical parameters and composition of the microflora of the oral cavity, secretory activity of the salivary glands and other processes of the maxillofacial region and the body as a whole. One of the methods that can be used in the treatment and prevention of prosthetic stomatitis is balneotherapy. In the article, using the clinical, biochemical, microbiological and histological methods, the effectiveness of the use of mineral water "Fateevskaya" in patients using removable orthopedic structures was studied. Objectives of the study was to evaluate the effectiveness of procedures for small balneotherapy with the use of mineral water "Fateevskaya" in patients with removable dentures. Methods.We examined 158 elderly and senile age patients with removable dentures. Correction of removable dentures was carried out to all patients at the initial stage. All examined patients are divided into two groups. The group received the treatment with the low balneotherapy with “Fateevskaya” mineral water (78 patients, and the clinical control group (80 patients). The clinical condition of oral cavity was assessed before and after the course of low balneotherapy. Were researched: changes of mucous membrane of prosthetic bed, salivation rates, disturbance of salivary secretion, oral microbiocenosis. Results.Of the research showed that in both groups were increase of pH value, appears lower values of total protein and glucose, decrease in activity of some enzymes. This explanation is due to a decrease in the stress response to using the removable dentures, normalization of salivary glands functioning, decrease in the intensity of the phlogiston process. The results of a histological research also confirm this. The results of microbiological crops before and after the low balneotherapy indicate the oral biocenosis normalization. The positive changes in the researched parameters had significantly larger statistically valid values in the group received the treatment with the low balneotherapy with “Fateevskaya” mineral water. The results of the complex research allow us to recommend the “Fateevskaya” mineral water to low balneotherapy in dental practice.
