Effect of Different Intensities of Aerobic Exercise Combined with Resistance Exercise on Body Fat, Lipid Profiles, and Adipokines in Middle-Aged Women with Obesity.

We aimed to investigate the effect of different intensities of aerobic exercise (VO2max: 50% vs. 80%) on body weight, body fat percentage, lipid profiles, and adipokines in obese middle-aged women after 8 weeks of combined aerobic and resistance exercise. The participants included 16 women aged >40 years with a body fat percentage of ≥30%; they were randomly assigned to the resistance and either moderate (RME, 50% VO2max, 200 kcal [n = 8]) or vigorous aerobic exercise groups (RVE, 80% VO2max, 200 kcal [n = 8]), respectively. After 8 weeks of exercise, we observed that body weight and body fat percentage decreased significantly in both groups (p < 0.01). The total cholesterol (p < 0.01) and LDL (p < 0.05) levels decreased significantly in the RME group, while triglyceride levels decreased significantly in both groups (p < 0.01). The HDL levels tended to increase only slightly in both groups. The adiponectin levels decreased significantly in the RVE group (p < 0.05), and the leptin levels decreased significantly in both groups (p < 0.05). To prevent and treat obesity in middle-aged women, combined exercise (aerobic and resistance) is deemed effective; additionally, aerobic exercise of moderate intensity during combined exercise could be more effective than that of vigorous intensity.

Effects of exercise type and intensity on visfatin and the metabolic syndrome in obesity / Efectos del tipo de ejercicio y de la intensidad en la visfatina y el síndrome metabólico en la obesidad / Efeitos do tipo de exercício e da intensidade na visfatina e a síndrome metabólica na obesidade

ABSTRACT Objective: Visfatin may regulate a variety of physiological functions and it has great potential to significantly enhance our knowledge of the treatment of metabolic syndrome. Metabolic syndrome (MS) refers to metabolic abnormalities, such as abdominal obesity, dyslipidemia, high low-density cholesterol, high blood pressure and diabetes, and physical activity is an important factor for the management of MS. Therefore, the purpose of this study is to investigate the effects of visfatin on MS and MS risk factors through differences in aerobic exercise intensity and exercise type based on the premise of the same amount of exercise (energy expenditure of 400 kcal per day). Method: Thirty two obese, middle-aged women were randomly assigned to exercise intensity groups VO2max 50% (MAE, n=8) and VO2max 80% (VAE, n=8) and to type of exercise groups VO2max 50% + TRX (MARE, n=8) and VO2max 80% + TRX (VARE, n=8). The exercise program was performed 5 times a week. The data was analyzed using two-way repeated measures ANOVA and post-hoc tests within groups with LSD. Results: Body weight (p<.01 and p<.001) and % body fat (p<.05 and p<.01) significantly decreased in all groups and visfatin only increased significantly after exercise in the VARE group (p<.05). TG, glucose, and waist circumstance (p<.05, p<.01, and p<.001) significantly decreased in all groups and HDL-C (p<.05) only increased significantly after exercise only in the MARE group. Conclusion: These results suggest that, in spite of differences in exercise intensity and exercise type, exercise is effective in improving obesity and MS risk factors, but further research is needed on the exact mechanisms of visfatin.

RESUMEN Objetivo: La visfatina puede regular diversas funciones fisiológicas y tiene gran potencial para mejorar significativamente nuestro conocimiento sobre el tratamiento del síndrome metabólico. El síndrome metabólico (SM) se refiere a anormalidades metabólicas, como obesidad abdominal, dislipidemia, colesterol de baja densidad elevado, hipertensión y diabetes, siendo la actividad física un factor importante para el manejo del SM. Siendo así, el objetivo de este estudio es investigar los efectos de la visfatina sobre los factores de riesgo de SM por medio de diferencias de la intensidad de ejercicios aeróbicos y del tipo de ejercicio, con base en la premisa de misma cantidad de ejercicio (gasto energético de 400 kcal por día). Método: Treinta y dos mujeres obesas de media edad fueron aleatoriamente designadas para grupos de intensidad de ejercicio con VO2máx de 50% (EAM, n = 8) y VO2máx de 80% (EAV, n = 8) y grupos con VO2máx de 50% + ERC (EARM, n = 8) y VO2máx de 80% + ERC (EARV, n = 8). El programa de ejercicios fue realizado cinco veces por semana. Los datos fueron analizados con ANOVA de dos vías con medidas repetidas y tests post-hoc en los grupos con DMS. Resultados: El peso corporal (p < 0,01 y p < 0,001) y porcentual de grasa corporal (p < 0,05 y p < 0,01) disminuyeron significativamente en todos los grupos y la visfatina sólo aumentó significativamente después del ejercicio en el grupo EARV (p < 0,05). Los triglicéridos, la glucosa y la circunferencia de la cintura (p < 0,05, p < 0,01 e p < 0,001) disminuyeron significativamente en todos los grupos y el HDL-C (p < 0,05) sólo aumentó significativamente después del ejercicio sólo en el grupo EARM. Conclusión: Esos resultados sugieren que, a pesar de las diferencias de intensidad y tipo de los ejercicios, los mismos son eficaces para mejorar la obesidad y los factores de riesgo del SM, por ende, son necesarias más investigaciones sobre los mecanismos exactos de la visfatina.

Improving the quality of sexual history disclosure on sex offenders: Emphasis on a polygraph examination.

The increasing recidivism rate of sex offenders indicates potential problems in existing recidivism programs. The present study was conducted to determine whether the polygraph examination is a useful technique to obtain a sex offender's concealed past sexual history. We collected fifty-two sex offenders' data and analyzed it. Among the 52 participants, the court ordered 26 sex offenders to take the psychiatric evaluation and the polygraph test. The other half were prisoners at the hospital who were currently undergoing treatment. The participants in the polygraph group disclosed more deviant sexual behaviors and paraphilia interests/behaviors than the comparison group. Thus, the polygraph examination is a powerful tool that can encourage sex offenders to disclose hidden information to help create suitable psychological therapy programs for preventing recidivism in the future.

Analysis of Variation and Ferroelectric Layer Thickness on Negative Capacitance Nanowire Field-Effect Transistor.

We investigate the interrelation between some variations and the stability of Negative Capacitance Field-Effect Transistors (NC FETs). When a variation effect is considered, stability issues which are making hysteretic operation should be considered for NC FETs as well. In this paper, to make sure of stability and hysteresis-free operation, a thickness margin of ferroelectric layer is suggested. It is the easiest solution for designing and surest method of vouching for hysteresis-free operation. Although some disadvantages which make subthreshold swing (SS) a bit higher than without a margin on thickness of ferroelectric layer (TFE) can be caused, both still high performance and stable operation can be achieved.

Effect of Various Geometry Parameters on the Performance of Nanoplate Field Effect Transistor with Negative Capacitance.

In this paper, we investigate the impact of geometry parameters such as ferroelectric layer thickness (TFE), extension length (LExt), overlap length (Lov) on negative capacitance FET (NCFET). The NCFET is designed using HfZrO2 (HZO) ferroelectric materials and the Nanoplate FET (NPFET) presented as a next generation device. We use the 3-D TCAD Sentaurus simulator to analyze characteristics of the NCFET. The NCFET designed considering the stable condition overcomes the Boltzmann limit (i.e., the physical limit in the S.S., which is 60 mV/decade at 300 K) through the steep subthreshold swing (S.S.) and exhibits negative Drain-induced barrier lowering (DIBL) phenomenon. When examining the characteristics of NPFET and NCFET according to LExt and Lov, the NCFET exhibits gate capacitance (Cgg) tendency opposite to that of the NPFET. The NCFET with the scaled VDD has a significant advantage over the gate delay (τd). The NCFET has better performance in environments where conventional device is more vulnerable to short channel effects (SCEs).

Therapeutic Effects of Leuprorelin (Leuprolide Acetate) in Sexual Offenders with Paraphilia.

BACKGROUND: This study examined the clinical effects of leuprolide acetate in sexual offenders with paraphilic disorders evaluated by means of objective psychiatric assessment. METHODS: The subjects of this study were seven sexual offenders who were being treated by means of an injection for sexual impulse control by a court order. They had been diagnosed with paraphilia by a psychiatrist based on the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) and had been put on probation by the Ministry of Justice between January 2016 and December 2016. RESULTS: After twelve months, we observed significant improvement in symptoms, as decrease of abnormal sexual interest and activity, sexual fantasy, Clinical Global Impression-Severity (CGI-S), and Clinical Global Impression-Impulsivity (GCI-I). There were a mild feminization of the body shape, feelings of fatigue, and mild hot flushes. No other adverse effect was reported. CONCLUSION: These results suggested that the clinical effects of leuprolide acetate in sexual offenders might be an effective treatment and safety strategy.

Chronic stress-induced dendritic reorganization and abundance of synaptosomal PKA-dependent CP-AMPA receptor in the basolateral amygdala in a mouse model of depression.

Chronic stress is a precipitating factor for disorders including depression. The basolateral amygdala (BLA) is a critical substrate that interconnects with stress-modulated neural networks to generate emotion- and mood-related behaviors. The current study shows that 3 h per day of restraint stress for 14 days caused mice to exhibit long-term depressive behaviors, manifested by disrupted sociality and despair levels, which were rescued by fluoxetine. These behavioral changes corresponded with morphological and molecular changes in BLA neurons, including chronic stress-elicited increases in arborization, dendritic length, and spine density of BLA principal neurons. At the molecular level, calcium-permeable α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (CP-AMPARs) within the synaptosome exhibited an increased GluR1:GluR2 subunit ratio. We also observed increased GluR1 phosphorylation at Ser 845 and enhanced cyclic AMP-dependent protein kinase (PKA) activity in the BLA. These molecular changes reverted to the basal state post-treatment with fluoxetine. The expression of synaptophysin (SYP) and postsynaptic density protein 95 (PSD-95) at BLA neuronal synapses was also enhanced by chronic stress, which was reversed post-treatment. Finally, chronic stress-provoked depressive behavior was overcome by local blockage of CP-AMPARs in the BLA via stereotaxic injection (IEM-1460). Chronic stress-elicited depressive behavior may be due to hypertrophy of BLA neuronal dendrites and increased of PKA-dependent CP-AMPAR levels in BLA neurons. Furthermore, fluoxetine can reverse chronic stress-triggered cytoarchitectural and functional changes of BLA neurons. These findings provide insights into depression-linked structural and functional changes in BLA neurons.

Chronic exercise prevents repeated restraint stress-provoked enhancement of immobility in forced swimming test in ovariectomized mice.

We assessed whether chronic treadmill exercise attenuated the depressive phenotype induced by restraint stress in ovariectomized mice (OVX). Immobility of OVX in the forced swimming test was comparable to that of sham mice (CON) regardless of the postoperative time. Immobility was also no difference between restrained mice (exposure to periodic restraint for 21 days; RST) and control mice (CON) on post-exposure 2nd and 9th day, but not 15th day. In contrast, the immobility of ovariectomized mice with repeated stress (OVX + RST) was profoundly enhanced compared to ovariectomized mice-alone (OVX), and this effect was reversed by chronic exercise (19 m/min, 60 min/day, 5 days/week for 8 weeks; OVX + RST + Ex) or fluoxetine administration (20 mg/kg, OVX + RST + Flu). In parallel with behavioral data, the immunoreactivity of Ki-67 and doublecortin (DCX) in OVX was significantly decreased by repeated stress. However, the reduced numbers of Ki-67- and DCX-positive cells in OVX + RST were restored in response to chronic exercise (OVX + RST + Ex) and fluoxetine (OVX + RST + Flu). In addition, the expression pattern of cAMP response element-binding protein (CREB) and calcium-calmodulin-dependent kinase IV (CaMKIV) was similar to that of the hippocampal proliferation and neurogenesis markers (Ki-67 and DCX, respectively). These results suggest that menopausal depression may be induced by an interaction between repeated stress and low hormone levels, rather than a deficit in ovarian secretion alone, which can be improved by chronic exercise.

Effect of L-carnitine supplementation and aerobic training on FABPc content and beta-HAD activity in human skeletal muscle.

Both regular physical exercise and carnitine supplementation exert a role in energy metabolism and may improve endurance capacity. We investigated whether a combination of long-term carnitine ingestion and exercise training reveals any interactive effects on cytosolic fatty acid-binding protein (FABPc) expression and beta-hydroxyacyl CoA dehydrogenase (beta-HAD) activity in human skeletal muscle. Twenty-eight untrained healthy males randomly divided into four experimental groups: a placebo (CON; n = 7), exercise training (ET; n = 7, 40 min session(-1), five times per week at 60% VO2max), carnitine supplementation (CS; n = 7, 4 g day(-1)), and exercise training and carnitine supplementation (CT; n = 7). Before and after 6-week treatment, muscle biopsy samples were taken from the vastus lateralis. Nonesterified carnitine and acid-soluble acylcarnitine concentrations were increased in CT (P < 0.05), and serum triacylglycerol concentration was elevated almost twofold in ET and CT (P < 0.05). No interactive effects in FABPc expression were shown from any of treatment groups. Although FABPc increased by 54% in ET compared to CON, it failed to reach statistical significance. In addition, there was no change in FABPc expression from any of experimental groups. Similar trends with FABPc contents were demonstrated in beta-HAD activity. It is concluded that the combination of exercise training and L-carnitine supplementation does not augment in FABPc expression and beta-HAD activity in human skeletal muscle indicating that combined treatment does not exert additive effect in fat metabolism. Thus L-carnitine supplementation would be unlikely to be associated with the enhanced exercise performance.
