RESUMEN

Background/Objective: There is little research on the effectiveness of new approaches to psychology, including mindfulness-acceptance-commitment, especially in team disciplines. Therefore, this study compared mindfulness-acceptance and commitment-based approaches to rumination, cognitive flexibility, and sports performance of elite beach soccer players during a two-month follow-up. Methods: The research design consisted of a randomized controlled trial (RCT), with follow-up. Thus, 34 players of the premier league of beach soccer were randomly divided into intervention and control groups based on mindfulness acceptance and commitment. The experimental group exercises consisted of one session per week for 7 weeks and daily homework. Participants filled out the questionnaires of the Ruminative Response Scale, Cognitive Flexibility Inventory, and Sports Performance Questionnaire before, after, and at two months of follow-up of the intervention. Results: Multivariate Analysis of Variance (MANOVA) and Analysis of Variance (ANOVA) with repeated measures were used to evaluate the changes over time and compare the scores of the subjects of the two groups. The results showed a significant difference in mindfulness-acceptance and commitment intervention in the experimental group on pre- vs. post-test and pre-test vs. follow-up scores of research variables. Also, a comparison of groups using independent T-test analysis showed a significant effect of mindfulness-acceptance and commitment exercises on research variables in the experimental group in the post-test and follow-up stages. Conclusion: Findings suggest that mindfulness, commitment, and acceptance exercises can be used as a new method to reduce rumination and increase cognitive flexibility and sports performance of elite beach soccer players.

RESUMEN

INTRODUCTION: Exploring the potential of exercise in the rehabilitation process of patients with Parkinson's (PD) may be an interesting treatment perspective. Exercise-induced responses derived from neurotrophic elements appear to ameliorate the decline in neurodegeneration. Despite this understanding, the literature needs to be updated. AREAS COVERED: Our review focuses on: a) the key mechanisms of exercise on PD, highlighting mainly the responses related to neuroplasticity; b) the effects induced by different traditional types of exercise, also highlighting the effects of complementary therapies related to movement; c) the volume of exercise required to support efficient results are explored in the context of PD. Additionally, the proposition of new clinical application strategies in the context of PD will also be determined. EXPERT OPINION: It is suggested that different intensities of aerobic exercise be explored for the treatment of PD. The results associated with high intensity seem promising for performance, physiological and clinical parameters, such as BDNF production and cognition. On the other hand, the diversification of tasks and repetition of motor gestures appear as consistent arguments to exercise prescription. Finally, for future investigations, the neuromodulation strategy in association with aerobic exercise appears as a potential inducer of benefits on gait and cognitive function.

RESUMEN

Oxidative stress is known to be involved in development of numerous diseases including cardiovascular, respiratory, renal, kidney and cancer. Thus, investigations that mimic oxidative stress in vitro may play an important role to find new strategies to control oxidative stress and subsequent consequences are important. Rotenone, widely used as a pesticide has been used as a model to simulate oxidative stress. However, this chemical was found to produce several diseases. Therefore, the aim of this study was to investigate the antioxidant and cytoprotective effect of avocado (Persea americana Mill) extract and oil in monkey kidney epithelial cells (VERO) exposed to rotenone. VERO cells were exposed to IC50 of rotenone in conjunction with different concentrations of avocado extract and oil (ranging from 1 to 1000 µg/ml), for 24 hr. Subsequently, cell viability and oxidative metabolism were assessed. Data demonstrated that avocado extract and oil in the presence of rotenone increased cellular viability at all tested concentrations compared to cells exposed only to rotenone. In addition, extract and avocado oil exhibited antioxidant action as evidenced by decreased levels of reactive oxygen species (ROS), superoxide ion, and lipid peroxidation, generated by rotenone. Further, avocado extract and oil appeared to be safe, since these compounds did not affect cell viability and or generate oxidative stress. Therefore, avocado appears to display a promising antioxidant potential by decreasing oxidative stress.

RESUMEN

More than 500 molecules have been identified as components of Cannabis sativa (C. sativa), of which the most studied is Δ9-tetrahydrocannabinol (Δ9-THC). Several studies have suggested that Δ9-THC exerts diverse biological effects, ranging from fragmentation of DNA to behavioral disruptions. Currently, it is accepted that most of the pharmacological properties of Δ9-THC engage the activation of the cannabinoid receptors, named CB1 and CB2. Interestingly, multiple pieces of evidence have suggested that the cannabinoid receptors play an active role in the modulation of several diseases leading to the design of synthetic cannabinoid-like compounds. Advances in the development of synthetic CB1 cannabinoid receptor selective agonists as therapeutical approaches are, however, limited. This review focuses on available evidence searched in PubMed regarding the synthetic CB1 cannabinoid receptor selective agonists such as AM-1235, arachidonyl-2' chloroethylamide (ACEA), CP 50,556-1 (Levonantradol), CP-55,940, HU-210, JWH-007, JWH-018, JWH-200 (WIN 55,225), methanandamide, nabilone, O-1812, UR-144, WIN 55,212-2, nabiximols, and dronabinol. Indeed, it would be ambitious to describe all available evidence related to the synthetic CB1 cannabinoid receptor selective agonists. However, and despite the positive evidence on the positive results of using these compounds in experimental models of health disturbances and preclinical trials, we discuss evidence in regards some concerns due to side effects.

RESUMEN

BACKGROUND: Prostate cancer is the most common visceral neoplasia in men and frequently presents chemotherapy resistance. In this context, lemongrass (Cymbopogon citratus (D.C.) Stapf) has been studied since it presents many important biological activities, such as anticancer. OBJECTIVE: We investigated the antitumor effect of lemongrass and in chemotherapy activity using prostate cancer cells line (DU-145). METHODS: DU-145 cells were exposed to different concentrations of aqueous extract of lemongrass (30; 100; 300; 500 and 1000 µg/mL), isolated and in combination with docetaxel, during 24 and 72 hours. After, cell viability and proliferation, oxidative metabolism, colony formation and cell cycle analyses were performed. Also, we exposed the African green monkey kidney cell line (VERO) to the same lemongrass concentrations to investigate a possible toxicity of this extract. RESULTS: Our findings suggested that lemongrass presented an antitumor effect and improved docetaxel chemotherapy activity by decreasing cell viability and proliferation as well as colony formation. Moreover, we found an oxidative stress increased and cell cycle arresting in G0 /G1 phase. In addition, this extract presented selectivity action for cancer cells, since it did not cause cytotoxicity in normal cells, ensuring non-toxic therapeutic concentrations. CONCLUSION: Lemongrass is a promising medicinal plant that could be used during chemotherapeutic treatment, in order to potentiate the antitumor response and decrease the resistance of prostate cancer.

RESUMEN

Depression represents a common public health problem in the world. Depression in the elderly appears to follow a vulnerability-stress model, with an interaction between individual vulnerabilities, including genetic factors, age-related cognitive and neurobiological changes, and a variety of stressful events that occur more frequently in advanced ages, such as grief, financial problems, and reduction in autonomy/functionality. In the last decades, several studies have indicated that exercise can be effective in preventing or reducing depressive symptoms, both in healthy and psychiatric populations. Due to the scientific community's interest in the efficacy and safety of physical exercise as complementary therapy for depressed elderly patients, we conduct an opinion study on the subject. Despite the researchers' efforts, in the last decades little progress has been made in verifying the efficacy of exercise in geriatric depression.


A depressão representa um problema comum de saúde pública no mundo. A depressão em idosos parece seguir um modelo de vulnerabilidade-estresse, com uma interação entre vulnerabilidades individuais, incluindo fatores genéticos, mudanças cognitivas e neurobiológicas relacionadas à idade, e uma variedade de eventos estressantes que ocorrem mais frequentemente em idades avançadas, como luto, problemas financeiros e redução da autonomia/funcionalidade. Nas últimas décadas, vários estudos indicaram que o exercício pode ser eficaz na prevenção ou redução dos sintomas depressivos, tanto em populações saudáveis como psiquiátricas. Devido ao interesse da comunidade científica na eficácia e segurança do exercício físico como terapia complementar para idosos deprimidos; realizamos um estudo de opinião sobre o assunto. Apesar dos esforços dos pesquisadores, nas últimas décadas pouco progresso foi feito na verificação da eficácia do exercício na depressão geriátrica.

RESUMEN

There is enough evidence that, nowadays, the sedentary lifestyle is one of the major health problems worldwide, linked to many chronic diseases, including mental comorbidities, systemic hypertension, metabolic dysregulation, and cancer. Although health societies recommend engagement to physical activities, there is an overwhelming number of people remaining sedentary, even knowing the health benefits of regular exercises. One of the main factors that justifies this scenario is the lack of motivation, which is a barrier to people intended to start new habits for health. Considering this previous information, new alternatives for exercises may help people engage in a healthier lifestyle. Technology has contributed to this with devices that allow movements based on virtual reality approaches, including the exergames. These are games available even in commercial devices, as video-games, that allow people to work with different physical components. Furthermore, exergames add cognitive gain through its dual-task characteristic. Moreover, due to the combination of these benefits, they are feasible to acquire, and easy to use. Exergames are not only a potential strategy to reduce sedentary lifestyle but also a good method to improve health gains and rehabilitation in different populations and pathological conditions: older adults, stroke survivors, and Parkinson's disease. In this review, we aim to demonstrate some conditions that literature supports the intervention with exergames due to its physical and cognitive benefits. Furthermore, at the end of this review, we also explore the neurobiological mechanisms behind virtual-reality based exercises.

RESUMEN

The current study investigated the comprehension of mindfulness-based cognitive behavioral therapy (MBCT) by patients with resistant depression at the Psychiatry Institute of the Federal University of Rio de Janeiro, Brazil. This was the first time the model was used in the institution to treat these patients. In this study, 45 patients were invited to participate in a baseline session of MBCT that consisted in the explanation of the model and experimental exercises conducted by two experienced therapists. Twenty eight patients accepted to participate. At the end of the intervention, the patients completed a self-administered questionnaire designed by our ambulatory to assess their understanding of the method's goals. Patients with anxiety disorder was also accessed for group comparison. More than 75% of the patients rated the intervention as comprehensible and workable. Compared to patients with depression, patients with anxiety had a better understanding of the mindfulness framework (6.5%) and the meaning of cognitive behavioral therapy (17.6%). Patients that completed the intervention described the baseline session of MBCT as comprehensive and acceptable. These results may allow possible future developments in the practice of mindfulness as a treatment applicable in many condition and settings even in the Brazilian context.

RESUMEN

INTRODUCTION: Exergames represent a way to perform physical activity through active video games, serving as potentially useful tool in the field of neurorehabilitation. However, little is known regarding the possible role of exergames in improving cognitive functions in persons suffering from neurological disabilities. EVIDENCE ACQUISITION: A search for relevant articles was carried out on PubMed/Medline, Scopus, PEDro, and Google Scholar. Only randomized controlled studies and non-randomized but controlled studies were retained. The following additional inclusion criteria were applied: studies focused on physical activity interventions carried out by means of exergames; populations targeted were affected by neurological disabilities; and reported results were related to cognitive outcomes. We calculated standardized mean differences (SMD) and pooled results using a random effects meta-analysis. EVIDENCE SYNTHESIS: Of 520 abstracts screened, thirteen studies met the criteria to be included yielding a total of 465 participants, 233 randomized to exergames, and 232 allocated to the alternative or no intervention. The included studies varied in terms of studied populations (e.g., multiple sclerosis, post-stroke hemiparesis, Parkinson's disease, dementia, dyslexia, Down syndrome), type and duration of interventions, and cognitive outcome measures. Exergames significantly improved executive functions (SMD=0.53, P=0.005; 8 studies, N.=380) and visuo-spatial perception (SMD=0.65, P<0.0001; 5 studies, N.=209) when compared to the alternative or no intervention. There were no significant differences for attention (SMD=0.57, P=0.07; 7 studies, N.=250) and global cognition (SMD=0.05, P=0.80; 6 studies, N.=161). CONCLUSIONS: Exergames are a highly-flexible tool for rehabilitation of both cognitive and motor functions in adult populations suffering from various neurological disabilities and developmental neurological disorders. Additional high-quality clinical trials with larger samples and more specific cognitive outcomes are needed to corroborate these preliminary findings. CLINICAL REHABILITATION IMPACT: Exergames could be considered either as a supplemental treatment to conventional rehabilitation, or as strategy to extend benefits of conventional programs at home.

RESUMEN

BACKGROUND: Effect of Heteropterys aphrodisiaca (dog-node) on anxiety and function of adult female wistar mice. The project is an experiment with the use of H. aphrodisiac root extract, in order to observe the frequency of sexual exposure of females exposed to the extract, quantify the effect of the extract on the concentration of total testosterone and observe the anxiety levels of the animals exposed. Results will be measured with the laboratory testosterone test and LCE and CA tests. METHODS: In preparation of the extract, the root was oven dried at 40°C and diluted in alcohol extract (100g of root for 1 liter of alcohol) and lyophilized. 40 adult female mice were enrolled, separated in control group (placebo) and treatment group (50 mg/kg/day) for 15, 30, 45 and 60 days. At each period, hormonal testosterone and anxiety levels by the Elevated-Cross Labyrinth (ECL) tests and Open Camp (CA) were measured in 10 animals that were later euthanized (SBNeC). RESULTS: The results showed an improvement in the decrease of anxiety, as shown in the variables of number of open arm entries, time on the same side of the field, less avoidance and leakage. However, it appears that the time of exposure to the extract does not result in increased benefit, with possible decline of effect after 45 days of use. CONCLUSION: With this performed experiment with the "no-de-cachorro" extract, it was possible to understand a little more how this root can act in relation to anxiety, as predicted by the pharmacology that validates the animal models; anxiolytic components decrease anxiety-related behaviors, as shown in the variables of entry numbers in the open arm, time on the same side of the field, less avoidance and escape. However, it seems that the time of exposure to the extract does not modify the performance in the tests, observing until an apparent exhaustion of the anxiolytic action, which evidences the need for more specific studies on the possible effects of the extract.

RESUMEN

Stroke is one of the major causes of disability in the world. Due to the extended lifetime of the world's population, the number of people affected by stroke has increased substantially over the last years. Stroke may lead to sensorimotor deficits, usually causing hemiplegia or hemiparesia. In order to reduce motor deficits and accelerate functional recovery, MP combined with motor rehabilitation was introduced to the rehabilitation process of post-stroke patients. Evidence has shown that MP combining with motor rehabilitation based on activities of daily living was more effective than conventional motor rehabilitation used per se. This combination proved very useful and effective, with significant results in improvement of motor deficits in post-stroke patients. However, further studies must be conducted to determine specific parameters, such as type of imagery, frequency or duration.

RESUMEN

BACKGROUND: Contralaterally controlled functional electrical stimulation (CCFES) is an innovative method to improve upper extremity functions after stroke. OBJECTIVE: To compare the effects of CCFES versus neuromuscular electrical stimulation (NMES) on the upper extremity functions in patients with stroke. METHODS: Sixty patients with stroke were randomly assigned into CCFES group (n=30) or NMES group (n=30). All patients were also treated with conventional medical treatment and rehabilitation training. Patients in CCFES group received CCFES to the affected wrist extensors while the NMES group received NMES. The stimulus current was biphasic wave with a pulse duration of 200 µs and a frequency of 60 Hz. The electrical stimulation lasted for 20 min per session, 5 sessions per week for 3 weeks. The intensity of the CCFES was based on the electromyography (EMG) value of the unaffected side while the subjects voluntarily extended their unaffected wrist slightly (<10% range of motion, ROM), moderately (about 50% ROM) and completely (100% ROM). Fugl-Meyer assessment (FMA), motricity index (MI), the Hong Kong version of functional test for the hemiplegic upper extremity (FTHUE-HK) and active range of motion (AROM) of wrist extension were measured before and after 3 weeks of treatment. RESULTS: Compared with the baseline values, both groups showed significant improvements in all the measurements after treatment (p<0.05). Patients in CCFES group showed significantly higher upper extremity FMA, FTHUE-HK scores and AROM of wrist extension than those in NMES group (p<0.05). CONCLUSION: Compared with the conventional NMES, CCFES provides better recovery of upper extremity function in patients with stroke.

RESUMEN

Anxiety disorders are the most common psychiatric disorders observed currently. It is a normal adaptive response to stress that allows coping with adverse situations. Nevertheless, when anxiety becomes excessive or disproportional in relation to the situation that evokes it or when there is not any special object directed at it, such as an irrational dread of routine stimuli, it becomes a disabling disorder and is considered to be pathological. The traditional treatment used is medication and cognitive behavioral psychotherapy, however, last years the practice of physical exercise, specifically aerobic exercise, has been investigated as a new non-pharmacological therapy for anxiety disorders. Thus, the aim of this article was to provide information on research results and key chains related to the therapeutic effects of aerobic exercise compared with other types of interventions to treat anxiety, which may become a useful clinical application in a near future. Researches have shown the effectiveness of alternative treatments, such as physical exercise, minimizing high financial costs and minimizing side effects. The sample analyzed, 66.8% was composed of women and 80% with severity of symptoms anxiety as moderate to severe. The data analyzed in this review allows us to claim that alternative therapies like exercise are effective in controlling and reducing symptoms, as 91% of anxiety disorders surveys have shown effective results in treating. However, there is still disagreement regarding the effect of exercise compared to the use of antidepressant symptoms and cognitive function in anxiety, this suggests that there is no consensus on the correct intensity of aerobic exercise as to achieve the best dose-response, with intensities high to moderate or moderate to mild.

RESUMEN

Depression is a common and disabling disease that affects over 100 million people worldwide and can have a significant impact on physical and mental health, reducing their quality of life. Thus, the aim of this article was to provide information on research results and key chains related to the therapeutic effects of chronic aerobic exercise compared with other types of interventions to treat depression, which may become a useful clinical application in a near future. Researches have shown the effectiveness of alternative treatments, such as physical exercise, minimizing high financial costs and minimizing side effects. In this review, the data analyzed allows us to claim that alternative therapies, such as exercise, are effective on controlling and reducing symptoms. 69.3% of the studies that investigated the antidepressant effects of exercise on depressive were significant, and the other 30.7% of the studies improved only in general physiological aspects, such as increased oxygen uptake, increased use of blood glucose and decreased body fat percentage, with no improvement on symptoms of depression. From the sample analyzed, 71.4% was composed of women, and regarding the severity of symptoms, 85% had mild to moderate depression and only 15% had moderate to severe depression. However, there is still disagreement regarding the effect of exercise compared to the use of antidepressants in symptomatology and cognitive function in depression, this suggests that there is no consensus on the correct intensity of aerobic exercise as to achieve the best dose-response, with intensities high to moderate or moderate to mild.

RESUMEN

This paper describes the application of a glassy carbon electrode modified with a thin film of mesoporous silica/multiwalled carbon nanotubes for voltammetric determination of the fungicide carbendazim (CBZ). The hybrid material, (SiO2/MWCNT), was obtained by a sol-gel process using HF as the catalyst. The amperometric response to CBZ was measured at +0.73 V vs. Ag/AgCl by square wave voltammetry at pH 8.0. SiO2/MWCNT/GCE responded to CBZ in the linear range from 0.2 to 4.0 µmol L(-1). The calculated detection limit was 0.056 µmol L(-1), obtained using statistical methods. The SiO2/MWCNT/GCE sensor presented as the main characteristics high sensitivity, low detection limit and robustness, allowing CBZ determination in untreated real samples. In addition, this strategy afforded remarkable selectivity for CBZ against ascorbic and citric acid which are the main compounds of the orange juice. The excellent sensitivity and selectivity yielded feasible application for CBZ detection in orange juice sample.

RESUMEN

Anxiety and depression are pathologies that affect human beings in many aspects of life, including social life, productivity and health. Cannabidiol (CBD) is a constituent non-psychotomimetic of Cannabis sativa with great psychiatric potential, including uses as an antidepressant-like and anxiolytic-like compound. The aim of this study is to review studies of animal models using CBD as an anxiolytic-like and antidepressant-like compound. Studies involving animal models, performing a variety of experiments on the above-mentioned disorders, such as the forced swimming test (FST), elevated plus maze (EPM) and Vogel conflict test (VCT), suggest that CBD exhibited an anti-anxiety and antidepressant effects in animal models discussed. Experiments with CBD demonstrated non-activation of neuroreceptors CB1 and CB2. Most of the studies demonstrated a good interaction between CBD and the 5-HT1A neuro-receptor.

RESUMEN

[Purpose] Among the physical therapeutic procedures to decrease pain, there is transcutaneous electrical neural stimulation (TENS). There is no consensus about its efficacy for oncological patients, especially for post-mastectomy pain and eletrocortical changes in somatosensory areas. The aim of this study was to analyze acute electrocortical changes after TENS treatment of patients with intercostobrachial post mastectomy pain. [Subjects] Eighteen patients were divided into acupuncture (A) and burst (B) group. [Methods] In this pre and post-intervention study each group was measured for EEG analysis in absulte power in alpha band (8-14 Hz). Outcomes variables were the alpha waveband in the sensorymotor cortex and pain pre-and-post TENS intervention. Data were analyzed using ANOVA to compare times (rest, 10 and 15 min), group and electrodes. Pain was analyzed using percentual pain evaluation (PPE) in both groups. [Results] Outcomes indicate main effects of time and electrodes because of slow (8-10 Hz) and fast alpha (10-12 Hz) wavebands decreased. PPE reduced 88.4% in A and 66.3% in G. [Conclusion] TENS promoted electrical modification in the parietal region and a decrease in pain. Future studies should investigate other wave must be proposed for other bands and use different methods of EEG analysis to elucidate the actual mechanisms behind the efficacy of TENS treatment.

RESUMEN

The compression of the fourth ventricle (CV-4) is one of the more well known procedures in the cranial manipulation curriculum and practice. Cranial manipulation has received criticism because of the subtle, difficult to learn techniques, controversy over whether or not cranial bone structures move, and what if any clinical effects have been shown. The aim of this study was to measure the effects of CV-4 in 10 healthy subjects through quantitative electroencephalography (qEEG), specifically in alpha band. Participants were randomly distributed in control, sham-CV4 and CV4 conditions using a cross-over design. qEEG activity was recorded for each of the 10 subjects in each of the 3 conditions. There was a significant increase in the alpha absolute power between pre and post in the CV-4 condition. There appears to be potential for understanding the effect of the CV-4 if these finding are replicated in further clinical trials.

RESUMEN

Coenzyme Q10 (CoQ10) is critical for the cell power supply in mitochondria. CoQ10 shuttles electrons from complexes I and II to complex III, and can be anti-oxdiative. Neurons require high energy for synaptic transmission and therefore the mitochondria dysfunction often leads to severe neuronal degeneration, as observed in many neurological disorders. CoQ10 supplementation has been widely used to treat aging, stroke, neuromuscular diseases, Alzheimer's disease, Parkinson's disease, progressive supranuclear palsy, autosomal recessive cerebellar ataxias, Huntington's disease and amyotrophic lateral sclerosis. Here we discuss a large number of preclinical and clinical trials for CoQ10 to elucidate the mechanisms underlying CoQ10 therapy. The rational applications as a therapeutic agent in neurological disorders are discussed.

RESUMEN

Dentre os transtornos psiquiátricos, os transtornos de ansiedade (TAs) são os mais comuns, com prevalência em torno de 20% na população e, portanto, provocam grande prejuízo a pacientes e familiares. São vários os subtipos de transtornos de ansiedade e um diagnóstico correto se baseia em uma avaliação clínica cuidadosa. No presente artigo apresentamos os diagnósticos e os achados mais recentes sobre o tratamento com estimulação magnética transcraniana repetitiva (EMTr) para o transtorno de pânico, transtorno obsessivo-compulsivo, transtorno de estresse pós-traumático e fobia social.


Among psychiatric disorders, anxiety disorders (ATs) are the most common, with a prevalence of around 20% in the population and with great harm to patients and families. There are several subtypes of anxiety disorders and a correct diagnosis is based on a careful clinical assessment. In this paper we present the findings and the latest findings about treatment with repetitive transcranial magnetic stimulation (rTMS) for panic disorder, obsessive-compulsive disorder, post-traumatic stress and social phobia.
