The present study examined mood states of aerobic exercisers before and after completing a 15-wk. program. The subjects (ages 18 to 36 yr.) were 86 women enrolled in activity classes at a large state school in the southeast. Subjects were initially classified according to previous exercise habits. Analysis indicated both groups of frequent and infrequent exercisers were similar in mood states. Participation in regular exercise did not significantly change or enhance the mood states from pre-treatment measures. Pretest measures of mood states provided poor prediction of posttest measures, indicating extreme variability in subjects' scores.

Background There is a paucity of information about cardiovascular outcomes related to exercise habit change after a new diagnosis of atrial fibrillation (AF). We investigated the association between exercise habits after a new AF diagnosis and ischemic stroke, heart failure (HF), and all-cause death. Methods and findings This is a nationwide population-based cohort study using data from the Korea National Health Insurance Service. A retrospective analysis was performed for 66,692 patients with newly diagnosed AF between 2010 and 2016 who underwent 2 serial health examinations within 2 years before and after their AF diagnosis. Individuals were divided into 4 categories according to performance of regular exercise, which was investigated by a self-reported questionnaire in each health examination, before and after their AF diagnosis: persistent non-exercisers (30.5%), new exercisers (17.8%), exercise dropouts (17.4%), and exercise maintainers (34.2%). The primary outcomes were incidence of ischemic stroke, HF, and all-cause death. Differences in baseline characteristics among groups were balanced considering demographics, comorbidities, medications, lifestyle behaviors, and income status. The risks of the outcomes were computed by weighted Cox proportional hazards models with inverse probability of treatment weighting (IPTW) during a mean follow-up of 3.4 ± 2.0 years. The new exerciser and exercise maintainer groups were associated with a lower risk of HF compared to the persistent non-exerciser group: the hazard ratios (HRs) (95% CIs) were 0.95 (0.90–0.99) and 0.92 (0.88–0.96), respectively (p < 0.001). Also, performing exercise any time before or after AF diagnosis was associated with a lower risk of mortality compared to persistent non-exercising: the HR (95% CI) was 0.82 (0.73–0.91) for new exercisers, 0.83 (0.74–0.93) for exercise dropouts, and 0.61 (0.55–0.67) for exercise maintainers (p < 0.001). For ischemic stroke, the estimates of HRs were 10%–14% lower in patients of the exercise groups, yet differences were statistically insignificant (p = 0.057). Energy expenditure of 1,000–1,499 MET-min/wk (regular moderate exercise 170–240 min/wk) was consistently associated with a lower risk of each outcome based on a subgroup analysis of the new exerciser group. Study limitations include recall bias introduced due to the nature of the self-reported questionnaire and restricted external generalizability to other ethnic groups. Conclusions Initiating or continuing regular exercise after AF diagnosis was associated with lower risks of HF and mortality. The promotion of exercise might reduce the future risk of adverse outcomes in patients with AF.

Prostaglandins E2 And F2α

The influence of prostaglandins E2 and F2α on passage pressure across the uterotubal junction (UTJ) and isthmus were studied in rats that were either in the pro-oestrus, oestrus, metoestrus or dioestrus phases. Effects of these prostaglandins were also investigated in rats that had been either ovariectomized and treated with oestradiol or medroxiprogesterone acetate, or only ovariectomized. In each rat, the left UTJ was surgically resected and the isthmus anastomosed to the uterine horn, whereas the right UTJ was left untouched. The passage pressures across the left isthmus and the right UTJ were measured before and after prostaglandin treatment. The pressures obtained in the UTJ in the oestrus phase and oestrogen-treated ovariectomized animals were lower than those registered in the remaining groups. Prostaglandin E2 decreased the pressures when compared with pre-treatment measures in all groups. Significantly higher pressures were registered across the UTJ in prostaglandin F2α than in E2 treatment, with these higher pressures being similar to pre-treatment pressures. Both hormonal changes throughout the oestrous cycle and prostaglandin E2 treatment had a similar influence on the passage pressure across the isthmus, as that described for UTT, but with lower values. The results indicate that prostaglandin E2 decreases the passage pressure across both UTJ and isthmus and can have an influence on the regulation of transport across these 2 areas.

Objetivo: O presente estudo tem como objetivo verificar o estado de humor (antes e após) da pessoa acometida por acidente vascular encefálico (AVE) e a percepção sobre os fatores que influenciam a qualidade de vida dessa pessoa após o AVE. Métodos: Participaram do estudo, de forma voluntária, 07 pessoas, de ambos os sexos, com idade acima de 57 anos e que sofreram AVE há mais de 6 meses. Os participantes responderam a 3 instrumentos: (1) questionário sociodemográfico, (2) escala de humor de Brunel (BRUMS) e o (3) questionário abreviado de qualidade de vida (WHOQOL-bref). O BRUMS foi respondido para duas situações, com o objetivo de comparar o estado de humor antes e depois da ocorrência do AVE. Aplicaram-se análises descritivas no presente estudo. Resultados: No conjunto de resultados, a maioria dos participantes demonstrou alteração do estado de humor, tendo a maioria dos participantes um aumento dos escores das dimensões negativas, após o AVE. Além disso, em relação à qualidade de vida após o AVE, a maior parte dos participantes relata a importância do domínio psicológico para melhoria da qualidade de vida e atividade física e reabilitação como importantes fatores positivos. Conclusão: Pode-se concluir que o AVE tem grande influência na mudança de humor das pessoas; ou seja, após o AVE os acometidos apresentam a tendência de aumentarem o quadro de tristeza e depressão. Porém, observa-se que após o AVE os acometidos tendem a pensar mais na qualidade de vida e a buscar a mudança do estilo de vida, com o intuito de obterem um estilo de vida mais ativo e saudável.ABSTRACT. Mood state’s changes and quality of life’s perception in people affected with stroke. Objective: This study aims to verify the mood states (before and after) of the person who suffered the stroke and his perception about factors that influence person’s quality of life after the stroke event. Methods: Subjects of this study, volunteering themselves, both sexes, aged over 57 years and suffering from stroke for more than 6 months participated in the study. Participants answered 3 instruments: (1) sociodemographic questionnaire, (2) Brunel Mood Scale (BRUMS) and (3) Abbreviated Quality of Life questionnaire (WHOQOL-bref). BRUMS Scale was answered twice, in order to compare the mood perceived before and after the stroke event. Descriptive analyzes were undertaken in the present study. Results: In the set of results, the majority of the participants showed a change in the mood state, with the majority of participants having an increase into negative dimension scores. In addition, about quality of life after stroke, most participants report themselves the importance of the psychological domain to improve quality of life and physical activity and rehabilitation as important positive factors. Conclusions: It can be concluded that stroke has a great influence on people’s mood states swings. Although, after stroke, those affected for the accident have a tendency to increase their levels of sadness and depression. However, it is observed that after stroke, those affected tend to think more about their quality of life and to pursuit lifestyle changes, in order to achieve a more active and healthy lifestyle.

Background: Specific mood states were examined during the CrossFit Open, a consecutive 5-week fitness competition involving five separate CrossFit® workouts, to determine whether the unique design or strenuous workouts of the competition resulted in acute and/or chronic mood state alterations. Methods: Participants (n = 8) completed the Profile of Mood States (POMS) questionnaire one-week prior to the competition (baseline), prior to (PRE), immediately post (IP), 30-min post- (30P) and 60-min post-workout (60P) each week. Tension, depression, anger, confusion, fatigue and vigor were derived from the POMS, as was Total Mood Disturbance (TMD) and an Energy Index (EI). Results: Workout intensity exceeded 93% HRmax each week. No differences were observed between baseline and PRE-workout mood states across weeks, indicating little effect of the unique competition design. Significant (week x time) interactions were observed for TMD (p = 0.037), EI (p = 0.038) and fatigue (p = 0.005). Acute mood state fluctuations were consistent across each week, where mood states improved to and beyond PRE values 60-min post-workout. Conclusions: In competitors, the differences in workout design between each week did not influence mood states. This may be related to adaptation to this style of training, while the acute mood state alterations are likely due to the workout intensity.

Major Mediator

Glutamate is the major mediator of excitatory signals in the mammalian central nervous system. Extreme amounts of glutamate in the extracellular spaces can lead to numerous neurodegenerative diseases. We aimed to clarify the potential of the following vitamin E isomers, tocotrienol-rich fraction (TRF) and α-tocopherol (α-TCP), as potent neuroprotective agents against glutamate-induced injury in neuronal SK-N-SH cells. Cells were treated before and after glutamate injury (pre- and post-treatment, respectively) with 100 - 300 ng/ml TRF/α-TCP. Exposure to 120 mM glutamate significantly reduced cell viability to 76 % and 79 % in the pre- and post-treatment studies, respectively; however, pre- and post-treatment with TRF/α-TCP attenuated the cytotoxic effect of glutamate. Compared to the positive control (glutamate-injured cells not treated with TRF/α-TCP), pre-treatment with 100, 200, and 300 ng/ml TRF significantly improved cell viability following glutamate injury to 95.2 %, 95.0 %, and 95.6 %, respectively (p < 0.05).The isomers not only conferred neuroprotection by enhancing mitochondrial activity and depleting free radical production, but also increased cell viability and recovery upon glutamate insult. Our results suggest that vitamin E has potent antioxidant potential for protecting against glutamate injury and recovering glutamate-injured neuronal cells. Our findings also indicate that both TRF and α-TCP could play key roles as anti-apoptotic agents with neuroprotective properties.

AbstractThe presence of actinic keratoses (AKs) increases a patient’s risk of developing squamous cell carcinoma by greater than six-fold. We evaluated the effect of topical treatment with imiquimod on the tumor microenvironment by measuring transcriptomic differences in AKs before and after treatment with imiquimod 3.75%. Biopsies were collected prospectively from 21 patients and examined histologically. RNA was extracted and transcriptomic analyses of 788 genes were performed using the nanoString assay. Imiquimod decreased number of AKs by study endpoint at week 14 (p < 0.0001). Post-imiquimod therapy, levels of CDK1, CXCL13, IL1B, GADPH, TTK, ILF3, EWSR1, BIRC5, PLAUR, ISG20, and C1QBP were significantly lower (adjusted p < 0.05). Complete responders (CR) exhibited a distinct pattern of inflammatory gene expression pre-treatment relative to incomplete responders (IR), with alterations in 15 inflammatory pathways (p < 0.05) reflecting differential expression of 103 genes (p < 0.05). Presence of adverse effects was associated with improved treatment response. Differences in gene expression were found between pre-treatment samples in CR versus IR, suggesting that higher levels of inflammation pre-treament may play a part in regression of AKs. Further characterization of the immune micro-environment in AKs may help develop biomarkers predictive of response to topical immune modulators and may guide therapy.

This study aims to explore whether gender differences exist in the architectural and mechanical properties of the medial gastrocnemius–Achilles tendon unit (gMTU) in vivo. Thirty-six healthy male and female adults without training experience and regular exercise habits were recruited. The architectural and mechanical properties of the gMTU were measured via an ultrasonography system and MyotonPRO, respectively. Independent t-tests were utilized to quantify the gender difference in the architectural and mechanical properties of the gMTU. In terms of architectural properties, the medial gastrocnemius (MG)’s pennation angle and thickness were greater in males than in females, whereas no substantial gender difference was observed in the MG’s fascicle length; the males possessed Achilles tendons (ATs) with a longer length and a greater cross-sectional area than females. In terms of mechanical properties, the MG’s vertical stiffness was lower and the MG’s logarithmic decrement was greater in females than in males. Both genders had no remarkable difference in the AT’s vertical stiffness and logarithmic decrement. Gender differences of individuals without training experience and regular exercise habits exist in the architectural and mechanical properties of the gMTU in vivo. The MG’s force-producing capacities, ankle torque, mechanical efficiency and peak power were higher in males than in females. The load-resisting capacities of AT were greater and the MG strain was lesser in males than in females. These findings suggest that males have better physical fitness, speed and performance in power-based sports events than females from the perspective of morphology and biomechanics.

In this study, we confirmed effect of carbon pre-treatment on Pd dispersion in synthesis of Pd/C catalyst. Physical characteristics on the surface of before and after pre-treated carbon were analyzed by nitrogen adsorption-desorption analysis. The dispersion and size of Pd particles were analyzed by XRD, FE-TEM and CO-chemisorption. After pre-treatment, surface area of carbon were decreased. And mesopore area ratio were increased with decreasing micropore area ratio. In the case of pre-treated carbon, we confirmed high dispersion of Pd particles.

We aimed to investigate the effect of Taekwondo training on physical fitness, mood, sociality, and cognitive function among international students in South Korea. We randomly assigned 24 international students to a control group (CG, n = 12) and experimental group (EG, n = 12). The EG performed Taekwondo training for 16 weeks, while the CG did not train. Each participant underwent a physical fitness test and sociability questionnaire before and after the intervention. We also examined changes in mood state and cognitive function, using the Korean version of the Profile of Mood State-Brief (K-POMS-B), and the Stroop Color and Word test, respectively. Regarding the physical fitness variables, sit-and-reach records in the EG significantly increased after intervention (p < 0.05). In the sub-variable of K-POMS-B, Vigor-Activity scores significantly increased (p < 0.05) after intervention, while the Fatigue-Inertia scores significantly decreased in the EG (p < 0.05). Furthermore, in the EG, peer relationship scores, a sub-variable of sociability, significantly decreased after intervention (p < 0.05). These findings suggest that Taekwondo training can not only improve flexibility among physical fitness factors, but can also be effective in improving the mood state and sociality of international students.

Molybdenum disulphide (MoS2) is a popularly used solid lubricant in various applications due to its superior tribological behaviour. However, it possesses poor wear resistance which requires further improvement. In the present study efforts have been made to enhance the tribological properties of pure MoS2 coating film by doping TiO2 nanoparticles as a reinforcement material. The Manganese phosphating is selected as a pre-treatment method to improve the bond strength between coating and substrate. The coating is bonded with the substrate material employing sodium silicate as a binder. The effects of wt. % of TiO2 onto the mechanical properties of composite MoS2-TiO2 coating such as hardness and bond strength have been studied. In addition coating microstructure before and after experimental test was studied using optical microscope and scanning electron microscope. It was also found that with increase in wt. % addition of TiO2 upto 15% into MoS2 base matrix, the hardness of coating increases proportionally. Beyond 15 wt. % addition of TiO2, the coating becomes brittle in nature. This leads to reduction in the scratch resistance.
