Sensorimotor rhythm (SMR) activity has been related to automaticity during skilled action execution. However, few studies have bridged the causal link between SMR activity and sports performance. This study investigated the effect of SMR neurofeedback training (SMR NFT) on golf putting performance. We hypothesized that preelite golfers would exhibit enhanced putting performance after SMR NFT. Sixteen preelite golfers were recruited and randomly assigned into either an SMR or a control group. Participants were asked to perform putting while electroencephalogram (EEG) was recorded, both before and after intervention. Our results showed that the SMR group performed more accurately when putting and exhibited greater SMR power than the control group after 8 intervention sessions. This study concludes that SMR NFT is effective for increasing SMR during action preparation and for enhancing golf putting performance. Moreover, greater SMR activity might be an EEG signature of improved attention processing, which induces superior putting performance.

The aim of this study was the effect of Bio/Neurofeedback training on performance, audio and visual attention of elite shooters. In this study 36 elite shooters of Kermanshah Province participated. They divided in three groups. Two groups were experimental groups how participated biofeedback and neurofeedback training and one group was control group. All participants were tried that their trainings as well as the number of shoots were closely controlled in order to assure their physical and special trainings. In this study, for attention affects the computerized Integrated Visual and Auditory test (IVA) was used. This test has been considered as both a pretest and a posttest after the therapeutic intervention in three groups. The score of shooting also were collected before and after intervention. Each athlete in neurofeedback training group carried out the neurofeedback training for 20 sessions, each lasting 45 minutes. To do so, both auricles and T3 and PZ of each individual were cleaned using alcohol and new-perp gel to prepare for the neurofeedback training. The biofeedback training was heart rate and respiratory training.  To compare the results of the pretest and the posttest in each group, the dependent t-test was used. For compare three groups we used ANOVA test. The significance level was set at 0.05. The results indicated that there is a significant difference in three groups. It indicates a significant increase in the total score for attention after the implementation of the biofeedback and neurofeedback training. The results showed that the attention mean scores in three visual, audio, and total variables were higher in the posttest than in the pretest for two experimental groups. The results also indicated that the scores of the shoots were improved after training.  According the research finding, we can be said that the neurofeedback and biofeedback  training act on the waves of the sensory-motor beats and which are responsible for coordinating the sensory-motor acts of the brain waves and physiology parameters (Heart and respiratory systems), and strengthen these waves in addition to the beta ones and rate of the heart and respiration. This leads to regulating the performance and attention.

Dark chocolate is rich in flavonoids that can have effects on body composition and cognitive performance. The aim of this study was to analyze the effects of acute and subchronic chocolate intake on electrical brain oscillations. A study with 20 healthy subjects (mean age of 24.15 years) and a control group with five subjects (mean age of 23.2 years) was carried out. In the acute effect study, the subjects’ intake was dark chocolate (103.72 mg/kg of body weight) rich in flavonoids and low in calories as in fasting. In the control group, the subjects intake was only low-calorie milk. For the subchronic effect, a daily dose of dark chocolate was given for eight days. The baseline electroencephalogram (EEG) was recorded before dark chocolate intake; at 30 min, the second EEG was carried out; on the eighth day, the third and fourth EEGs were performed before and after the last intake. In acute and subchronic intake, Delta Absolute Power (AP) decrease was observed in most brain regions (p < 0.05), except in the right fronto-centro-temporal regions. In the Theta band, there was a generalized decrease of the AP of predominance in the left fronto-centro-temporal regions. In contrast, an increase in AP was observed in the temporo-occipital regions in the Alpha band, and in the right temporal and parieto-occipital regions in the Beta band. The control group did not have significant changes in brain oscillations (p > 0.05). We concluded that acute and subchronic chocolate intake decreased the Delta and Theta AP and increased Alpha and Beta AP in most brain regions.

Background: Non-invasive neurofeedback training is currently explored as a potential add-on therapy to treat patients suffering from major depressive disorder, and first trials show promising clin-ical effects. The temporal evolution of therapeutic change, however, remains unclear. Methods: Profile of mood states (POMS) questionnaire ratings were collected immediately before and after five sessions of real-time fMRI neurofeedback training (rt-fMRI-NFT) in a randomised controlled trial (RCT). Data were analysed for within and between treatment sessions ef-fects. Results: Trajectories of mood profiles varied between subscales. Total mood disturbance and the subscales depression and tension showed both within and between treatment sessions ef-fects, although within-session effects were descriptively larger. Limitations: The sample size was relatively small owed to the current state of the rt-fMRI-NFT field. No data from a sham-neurofeedback control group was available. Conclusions: The presented data provides a better understanding of when changes in mood states occur. The POMS questionnaire allows monitoring rapid and slowly evolving changes in mood states and can thus inform future study designs for neuromodulation and psychological in-terventions for mental disorders.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.

ABSTRACT The fractional determination of 17-ketosteroids in the daily urine was performed in nine cases of hyperemesis gravidarum and in four control cases, in the first trimester of pregnancy both before and after corticotrophin administration. The excretion of total 17-KS is similar in the two groups. Only in the hyperemesis group does the excretion of total 17-KS increase significantly after corticotrophin administration. The fractional determination reveals no difference between the two groups of patients with regard to the values of the fractions U (unidentified 17-KS), A (androsterone) and Rest (11-oxygenated 17-KS). The excretion of dehydroepiandrosterone is significantly higher in the hyperemesis group than in the control group. The excretion of androstanolone seems to be lower in the hyperemesis group than in the control group, but the difference is not statistically significant. The differences in the correlation between dehydroepiandrosterone and androstanolone in the two groups is significant. The high excretion of dehydroepiandrosterone and low excretion of androstanolone in cases of hyperemesis gravidarum is a sign of adrenal dysfunction.

The objective: was to examine the effectiveness of treatment of late miscarriage threat by micronized form of progesterone for 100 mg – 3 times a day in the form of gelatin pills and vaginal tablets with lactose. Patients and methods. Under our supervision there were 70 pregnant women with normocenosis of vagina (NCV) without extragenital pathology, which were not performed systemic or local treatment with antibacterial drugs in the last 4 weeks. Among them 25 pregnant women with TLSM treated by gelatin tablets of micronized progesterone (GTP) (group 1); 25 pregnant women with TLSM, treated by vaginal micronized progesterone tablets (VPT) (2nd group) and 20 healthy women with physiological pregnancy – PV (control group). The distribution of women in the group adhered to the principles of randomization. The age of examined women ranged from 19 to 32 years, most pregnant women were aged under 30 years (89.02%). General clinical examination was carried out according to the standard scheme according to the Order MH of Ukraine № 620. Results. During the research we have determined the colpocytologcal dynamics and state of vaginal microbiota in pregnant women with threatened late miscarriage with initial vaginal normocenosis before and after treatment whit vaginal forms of progesterone. Conclusion. The received results showed low efficiency of micronized progesterone gelatin dragee at threat of the late miscarriage that at small therapeutic effect has led to the development of vaginal dysbiosis in all surveyed. In contrast, the use of micronized progesterone vaginal tablets – the maximally rapid therapeutic effect without disturbance of vaginal normocenosis. Key words: the threat of a late miscarriage, vaginal micronized forms of progesterone.

Caring for the persons with first episode psychosis is challenging and demanding. It may lead to the increased burden, expressed emotions among the caregivers. The numerous studies have shown that high burden and negative expressed emotions among caregivers can lead to early relapse in the patients with first episode psychosis. To evaluate the effects of the brief psychoeducation on the caregivers burden and expressed emotions. A quasi experimental - before and after with control group research design was adopted for the study. A total of 60 caregivers have participated in the study, of which 30 caregivers in experimental group and 30 caregivers in the control group. Family Burden Interview Schedule (Pai and Kapoor, 1981) and Attitude Questionnaire (Sethi et al., 1981) was used to assess caregiver's burden and expressed emotions. At end of the psychoeducation intervention, burden among caregivers and negative expressed emotions of the caregivers have significantly reduced. The positive expressed emotions have been increased. Study results demonstrates the importance of psychoeducation intervention in reducing the burden and negative expressed emotions.
