SUMMARY OBJECTIVE Psychological distress is an important mental health problem among university students. The goal of this study was to determine psychological distress and its associated risk factors among students in the Anhui province. METHODS A cross-sectional study was conducted in a sample of 1304 students. In this study, a self-administered questionnaire consisting of the general demography and General Health Questionnaire (GHQ-12) was completed. Psychological distress was assessed using the GHQ-12-item questionnaire. A dichotomous category split was imposed on the GHQ-12 for the purpose of analysis. A GHQ-12 score of 4 or higher indicated psychological distress. The data were analyzed by SPSS 20.0 system. RESULTS A total of 1304 samples were analyzed in this study. The results indicated that the education level of the father and mother was associated with the students’ psychological distress (P<0.001). A significant association was found between high-intensity exercise and low-intensity exercise and psychological distress. However, no significant difference was identified between gender and psychological distress (P=0.173). CONCLUSION The education level of parents, high-intensity exercise, and low-intensity exercise were associated with psychological distress. Our results suggest that it is indispensable to raise awareness of psychological disorders and its associated risk factors among university students. Further studies are required to develop appropriate interventions for high-risk groups.

Background and Objectives: The purpose of this study was to elucidate the effects of different exercise intensities in preventing the decline of cognitive function and lipolysis associated with a high-fat diet-induced obesity in growing mice. Material and Methods: Forty male C57BL/6 mice, aged 4 weeks, were divided into the normal diet (CO, n = 10) and high-fat diet (HF, n = 30) groups to induce obesity for 8 weeks. Subsequently, the HF group was subdivided equally into the HF, HF + low-intensity training (HFLT), and HF + high-intensity training (HFHT) groups, and mice were subjected to treadmill training for 8 weeks. Results: Following the 8-week training intervention, body weight and fat mass were significantly lower in the training groups than in the HF group (p < 0.05). Adipose triglyceride lipase (ATGL), hormone-sensitive lipase (HSL), and monoglyceride lipase levels were significantly higher in the training groups than in the HF group (p < 0.05), and the ATGL and HSL levels were significantly higher in the HFHT group than in the HFLT group (p < 0.05). The Y-maze test showed that the training groups had a higher number of total entries and percent alternation than the HF group (p < 0.05). Hippocampal nerve growth factor, brain-derived neurotrophic factor, and neurotrophin-3 levels were significantly higher in the training group than in the HF group (p < 0.05). However, there was no significant difference according to the exercise intensity among the groups. Conclusions: The results of this study suggested that low-intensity exercise is as effective as a high-intensity exercise in preventing the decline of cognitive function and lipolysis, and far more effective in terms of an expected efficiency of workload and prevention of side effects.

ABSTRACT Introduction The aim of this study was to assess the wear resistance of four bulk-fill composite resin restorative materials cured using high- and low-intensity lights. Materials and methods Twenty-four samples were prepared from each composite resin material (Tetric N-Ceram, SonicFill, Smart Dentin Replacement, Filtek Bulk-Fill) resulting in a total of 96 samples; they were placed into a mold in a single increment. All of the 96 samples were cured using the Bluephase N light curing unit for 20 seconds. Half of the total specimens (n = 48) were light cured using high-intensity output (1,200 mW/cm2), while the remaining half (n = 48) were light cured using low-intensity output (650 mW/cm2). Wear was analyzed by a three-dimensional (3D) noncontact optical profilometer (Contour GT-I, Bruker, Germany). Mean and standard deviation (SD) of surface loss (depth) after 120,000 cycles for each test material was calculated and analyzed using one-way analysis of variance (ANOVA) with a significance level at p < 0.05. Results The least mean surface loss was observed for SonicFill (186.52 µm) cured using low-intensity light. No significant difference in the mean surface loss was observed when comparing the four tested materials with each other without taking the curing light intensity into consideration (p = 0.352). A significant difference in the mean surface loss was observed between SonicFill cured using high-intensity light compared with that cured using low-intensity light (p < 0.001). Conclusion A higher curing light intensity (1,200 mW/cm2) had no positive influence on the wear resistance of the four bulk-fill composite resin restorative materials tested compared with lower curing light intensity (650 mW/cm2). Furthermore, SonicFill cured using low-intensity light was the most wearresistant material tested, whereas Tetric N-Ceram cured using high-intensity light was the least wear resistant. Clinical significance The wear resistance was better with the newly introduced bulk-fill composite resins under low-intensity light curing. How to cite this article Alkhudhairy F.

Hasil penelitian menunjuk bahwa dalam kelompok sprinter dan non sprinter dan non-sprinter tidak terdapat perbedaan yang bermakna terhadap peningkatan kadar β-endorfin. Akan tetapi terdapat peningkatan bermakna persentase kadar β-endorfin pada kelompok intensitas tinggi dibandingkan kelompok intensitas sedang dan rendah. Baik untuk kelompok sprinter maupun non-sprinter. Waktu istirahat 30 menit setelah LI belum cukup untuk mengembalikan kadar β-endorfin ketingkat awal. Molecular response endorphins against interval exercise with various intensity in sprinter AbstractInterval Exercise (LI) is one of the training methods to improve and maintain the ability or and speed of running in the distance and the time that has been determined. This study aims to find a depiction of physiological and biochemical responses of endorphins levels to LI with various intensity of exercise high, medium, and low on sprinter and non-sprinter. This research uses a quasi-experimental method which consists of three stages of a measurement implementation. The subjects of this research are the sprinter Activity sports unit of college Universitas Negeri Yogyakarta consist of 17 people and the non-sprinter group of 15 people. Each group is divided into three smaller groups based on the intensity of the exercise are high-intensity group, medium, and low. The study was conducted by measuring physical characteristics in the form of HB, WB, and 100m run a speed test and blood sampling as much as 3 times 5 ml to measure the response of endorphins in high, medium, and low-intensity constancy. The data were taken before being given LI, during LI, and after 30 minutes break. The analysis was done using the ELISA method with an ANOVA statistic test. The result and the conclusion. The results showed that in the sprinter and non-sprinter groups there was no significant difference in elevated endorphin levels. However, there was a significant increase in the percentage of endorphins in high-intensity groups compared to the medium and low-intensity groups, both for sprinter and non-sprinter groups. Rest time 30 minutes after the LI is not enough to restore the level of endorphins to the initial level.

Introduction: Regular exercise training is a useful strategy to reduce inflammatory markers, but it is still unclear what type of training is better. Thus, this study compared the effects of 12-week of low-intensity resistance (Low-RT) and high-intensity interval aerobic training (High-IAT) on serum interleukin (IL)-6 levels and insulin resistance (IR) markers in obese and young men. Methods In this quasi-experimental study, 38 obese and young men (age = 28.4 ± 5.2 years and body fat% = 27.5 ± 1.5) randomly assigned into a low-RT (n=14), high-IAT (n=12) and control (CON, n=12) groups. An age-matched control group of non-obese men (age = 27.0 ± 5.9 years, body fat% = 15.5 ± 2.6 and n=15) were also recruited for baseline comparison. Subjects performed the training programs (Low-RT: 10 exercises at 30-50% of 1-repetition maximum, and High-IAT: 16-minute of interval running at 80-90% of maximum heartbeat with a 3-minute recovery between intervals) for 12 weeks and 3-day a week. Data analyzed using SPSS version 18. Results: The independent t-test showed that the concentrations of glucose (P = 0.01), insulin (P = 0.04) and IR-index (P = 0.02) in obese men was higher than the non-obese at baseline, but no significant difference was noted for IL-6 (P = 0.14). The 2-factor analysis of variance revealed that insulin and IR-index similarly and remarkably decreased in response to the training (P < 0.05), but remained unchanged with glucose and IL-6 (P > 0.05). Conclusion: In summary, insulin resistance markers in the obese men group were higher than in the non-obese men group, but no significant difference was detected in IL-6 in these groups. Insulin and IR-index decreased remarkably and similarly after training programs, but no significant changes were found in glucose and IL-6.

Numerous studies have shown that facial expressions influence trait impressions in the Western context. There are cultural differences in the perception and recognition rules of different intensities of happy expressions, and researchers have only explored the influence of the intensity of happy expressions on a few facial traits (warmth, trustworthiness, and competence). Therefore, we examined the effect of different intensities of Chinese happy expressions on the social perception of faces from 11 traits, namely trustworthiness, responsibility, attractiveness, sociability, confidence, intelligence, aggressiveness, dominance, competence, warmth, and tenacity. In this study, participants were asked to view a series of photographs of faces with high-intensity or low-intensity happy expressions and rate the 11 traits on a 7-point Likert scale (1 = “not very ××,” 7 = “very ××”). The results indicated that high-intensity happy expression had higher-rated scores for sociability and warmth but lower scores for dominance, aggressiveness, intelligence, and competence than the low-intensity happy expression; there was no significant difference in the rated scores for trustworthiness, attractiveness, responsibility, confidence, and tenacity between the high-intensity and low-intensity happy expressions. These results suggested that, compared to the low-intensity happy expression, the high-intensity happy expression will enhance the perceptual outcome of the traits related to approachability, reduce the perceptual outcome of traits related to capability, and have no significant effect on trustworthiness, attractiveness, responsibility, confidence, and tenacity.

A simple type of structure with two different fortification intensities was chosen to calculate, and the costs between the low intensity structure after reinforcement and the high intensity structure were compared. The possible economic losses of structures in different seismic fortification intensity was also compared in order to analysis the affect of intensity on the building economic effect. The result showed that the economic benefit of high intensity structure was 1.07, and the reinforced low intensity structure was 0.58. So the economic benefit of structure with reasonable seismic input was evident.

Objective: To find and compare the clinical and psychological effects of low and high-intensity aerobic training combined with resistance training in community-dwelling older men with post-COVID-19 sarcopenia symptoms. Design: Randomized control trial. Setting: University physiotherapy clinic. Participants: Men in the age range of 60–80 years with post-COVID-19 Sarcopenia. Intervention: All participants received resistance training for whatever time of the day that they received it, and that in addition they were randomized into two groups like low-intensity aerobic training group ( n = 38) and high-intensity aerobic training group ( n = 38) for 30 minutes/session, 1 session/day, 4 days/week for 8 weeks. Outcomes: Clinical (muscle strength and muscle mass) and psychological (kinesiophobia and quality of life scales) measures were measured at the baseline, fourth week, the eighth week, and at six months follow-up. Results: The 2 × 4 group by time repeated measures MANOVA with corrected post-hoc tests for six dependent variables shows a significant difference between the groups ( P < 0.001). At the end of six months follow up, the handgrip strength, −3.9 (95% CI −4.26 to −3.53), kinesiophobia level 4.7 (95% CI 4.24 to 5.15), and quality of life −10.4 (95% CI −10.81 to −9.9) shows more improvement ( P < 0.001) in low-intensity aerobic training group than high-intensity aerobic training group, but in muscle mass both groups did not show any significant difference ( P > 0.05). Conclusion: Low-intensity aerobic training exercises are more effective in improving the clinical (muscle strength) and psychological (kinesiophobia and quality of life) measures than high-intensity aerobic training in post-COVID 19 Sarcopenia.

The importance of supplements used with exercise is increasing day by day. In this study, it was aimed to evaluate the effects of creatine monohydrate (CrM) supplementation with different intensities of exercise on oxidative stress through dynamic thiol disulfide homeostasis. Fourty two BALB/c mice were used and randomly divided into 6 groups; control (C), low-intensity exercise (LIE), high-intensity exercise (HIE), C+CrM (4% of daily diet), LIE+CrM, and HIE+CrM groups. Exercise groups were performed low-intensity (8m/min/30min/day) and high-intensity (24m/min/30min/day) exercise on a mouse treadmill for 8 weeks. At the end of the experimental period, the thiol disulfide homeostasis levels analyzed by using a new automated measurement technique. When the native thiol and total thiol values were examined the difference between the groups was statistically significant (respectively, p=0.029, p=0,035). Creatine intake with exercise decreased native thiol and total thiol levels. However, serum disulfide levels were lower in LIE+CrM compared to other study groups, but there was no statistically significant difference. It is thought that creatine supplementation with exercise reduces the thiol-disulfide homeostasis burden of the organism, and that after the depletion of creatine stores, the sustainability of oxidant-antioxidant homeostasis can be extended, thus prolonging the duration of antioxidant resistance.

The lentil weevil, Bruchus lentis Frӧlich, (Coleoptera: Chrysomelidae: Bruchinae) is the most serious pest of lentil in Iran. Economic losses due to this pest reach up to 40% of the lentil crop. Over a two-year study (2012 and 2013) in Agricultural Research Station of Gachsaran Region, best timing of chemical control of B. lentis was determined. A field experiment with cultivation of lentil Sina variety Lens culinaris Medik was conducted in a randomized complete block design with five treatments and three replications. The treatments consisted of spraying four times (respectively, during the early flowering, 10 days after the first spraying, 10 days after the second spraying; 10 days after the third spraying) and control (without spraying). For the spraying from Endosulfan insecticide EC50% at ratio one liter per hectare was used. Three samples were taken from the pods and totally 150 pods from each replicate for contaminations of seeds were investigated. After the determination of the percent of seeds contamination, results were statistically analysed. Based on the results obtained, first spray treatment, with the mean contamination of 15.45% and second spray treatment with the mean contamination of 12.25% had the highest impact on reducing contamination lentil seeds to B. lentis and between them there was no statistically significant difference and were in one group. Therefore, spraying one time during the early flowering until 15 days after it was the best time to control of B. lentis.
