“…The CL assay was performed in LV and carried out with an LKB Rack Beta liquid scintillation spectrometer 1215 (LKB Producer AB), in the out-of-coincidence mode at room temperature (25°C to 27°C). Supernatants were diluted in 140mmol/L KCl and 20mmol/L phosphate buffer, pH 7.4, and added to glass tubes, which were placed in scintillation vials; 3mmol/L tert-butylhydroperoxide was added, and CL was determined up to the maximal level of emission [9,28]. …”

“…The reaction medium to determination of reduced glutathione (GSH) and oxidized glutathione (GSSG) concentrations contained 100mmol/L phosphate buffer (pH7.2), 2mmol/L nicotinamidedinucleotide phosphate acid, 0.2 U/mL glutathione reductase, and 70 mmol/L 5,50dithiobis (2-nitrobenzoicacid). For determination of GSSG concentration, the supernatant was neutralized with 2 mol/L potassium hydroxide for reaction with 70 mmol/L 5,50 dithiobis (2-nitrobenzoic acid), and absorbance values were measured at 420 nm [9,28]. …”

The risks of chronic diseases associated with the increasing consumption of fructose-laden foods are amplified by the lack of regular physical activity and have become a serious public health issue worldwide. Moreover, childhood eating habits are strongly related to metabolic syndrome in adults. Thus, we aimed to investigate the preventive role of exercise training undertaken concurrently with a high fructose diet on cardiac function, hemodynamics, cardiovascular autonomic modulation and oxidative stress in male rats after weaning. Male Wistar rats were divided into 4 groups (n = 8/group): Sedentary control (SC), Trained control (TC), Sedentary Fructose (SF) and Trained Fructose (TF). Training was performed on a treadmill (8 weeks, 40–60% of maximum exercise test). Evaluations of cardiac function, hemodynamics, cardiovascular autonomic modulation and oxidative stress in plasma and in left ventricle (LV) were performed. Chronic fructose overload induced glucose intolerance and an increase in white adipose tissue (WAT) weight, in myocardial performance index (MPI) (SF:0.42±0.04 vs. SC:0.24±0.05) and in arterial pressure (SF:122±3 vs. SC:113±1 mmHg) associated with increased cardiac and vascular sympathetic modulation. Fructose also induced unfavorable changes in oxidative stress profile (plasmatic protein oxidation- SF:3.30±0.09 vs. SC:1.45±0.08 nmol/mg prot; and LV total antioxidant capacity (TRAP)- SF: 2.5±0.5 vs. SC:12.7±1.7 uM trolox). The TF group showed reduced WAT, glucose intolerance, MPI (0.35±0.04), arterial pressure (118±2mmHg), sympathetic modulation, plasmatic protein oxidation and increased TRAP when compared to SF group. Therefore, our findings indicate that cardiometabolic dysfunctions induced by fructose overload early in life may be prevented by moderate aerobic exercise training.

“…Hence, MHT may be a factor that affects auditory function. Second, the benefits of exercise for postmenopausal health or neurocognitive function are related to a number of confounding factors, such as body mass index (BMI), personal history of diabetes mellitus and cardiovascular disease and smoking status [21][22][23][24][25][26][27][28] . Third, a series of experiments demonstrated that high-intensity levels of exercise alter the RT 29 .…”

Background The climacteric phase of menopausal transition (perimenopause) is marked by reproductive hormone fluctuations and reduced cognitive capacity. Exercise enhances neurocognitive performance. However, auditory perceptual sensitivity has not been examined. Purpose This study aimed to determine the effect of aerobic exercise on the response speed (reaction time) and error rate during auditory processing among perimenopausal women. Methods Three pitches (500, 1000, and 2000 Hz) were used during a simple auditory discrimination task, which was performed before and after exercise. We included 14 perimenopausal women and 17 right-handed young women (aged 46-54 years and 18-22 years, respectively). To achieve similar exercise intensity in both groups, we proposed two types of physical activities for each group. Mixed models statistics were used to analyze the reaction time and error rate before and after training in the two groups. Results Perimenopausal women exhibited a significantly longer reaction time than young women during the baseline auditory discrimination task (p< 0.05) but not during the second test. The error rate decreased significantly after exercise among perimenopausal women (p < 0.05) but not among young women. Thus, exercise had a stronger beneficial influence on auditory plasticity or sensitivity for perimenopausal women than for young women. Conclusion The ability of aerobic exercise to modulate auditory neurocognitive performance differs between the two groups. Aerobic exercise improves auditory discrimination performance specifically for perimenopausal women. These results provide preliminary evidence concerning the acoustic features of middle-aged women, underscoring the importance of exercise for preventing decline in auditory cognitive function in perimenopausal women.

“…Performing regular aerobic exercises can improve blood pressure and thus reduce hot flashes in postmenopausal women, in addition to controlling weight and reducing osteoporosis [17]. However, not all postmenopausal women can perform aerobic and anaerobic exercises as some may have cardiovascular diseases or may be in the early stages of osteoporosis [18,19].…”

Introduction:Menopause is accompanied by many physical and psychological symptoms that can affect the Quality of Life (QoL) of women. Nowadays, behavioral approaches, such as exercise programs, and herbal therapies are recommended to control menopause complications.Objective: This study aimed to compare the effects of exercise and licorice on the QoL of postmenopausal women. Materials and Methods:This quasi-experimental study was conducted in Arak City, Iran, in 2014. Sixty postmenopausal women were selected as study participants using the convenience sampling method and were divided into two equal groups (exercise and licorice) using a random number table. The licorice group received three tablets of licorice daily at three times, i.e., in the morning, noon, and night before meals, for 4 weeks; the exercise group adopted a regular walking program comprising 30-45 min of walking three times a week for 1 month.
