Aerobic exercise training reduces deep-frying oil-induced apoptosis of hippocampal tissue by reducing oxidative stress in male rats.

Deep-frying oil (DFO) contains high amounts of free radicals, and consuming foods prepared with this method causes damage to nervous tissue due to oxidative stress (OS). Since moderate-intensity aerobic exercise training (AT) reduces OS, the current search investigated the effects of AT on OS, apoptosis, and neurogenesis markers in the hippocampal tissue of DFO-fed rats. Eighteen Wistar male rats (200-280 gr) were randomly allocated to a control group fed with normal food (Con-ND), a control group receiving DFO (Con-DFO), and a group receiving DFO-aerobic exercise (EX-DFO) (n = 6 in each). DFO was gavaged for four weeks, five days a week, with a dose of 2 ml. AT included running on a treadmill for four weeks and five sessions per week (40 min per session). The expression of genes B-cell lymphoma 2 (BCL-2), Protein X associated with Bcl-2 (BAX), Caspase-3 (Casp-3), and Caspase-9 (Casp-9) was measured by PCR method. The ELISA method was used to calculate levels of Superoxide dismutase (SOD) and Catalase (CAT) activity, malondialdehyde (MDA), and Brain-Derived Neurotrophic Factor (BDNF). Also, the expression of the proteins Cannabinoid receptor type 1(CB1), Cannabinoid receptor type2 (CB2), Glial fibrillary acidic protein (GFAP), Neuronal nuclei (NeuN), and DNA fragmentation was evaluated by Immunohistochemical and TUNEL staining. DFO feeding led to a significant increase in apoptotic markers, such as BAX, Casp-3, and Casp-9 gene expression, and DNA fragmentation (p ≤ 0.05) while decreasing BDNF concentration SOD activity (p ≤ 0.05). AT significantly reduced the BAX, Casp-3, Casp-9, MDA, CB1, GFAP, and DNA fragmentation (p ≤ 0.05). In conclusion, AT can reduce the harmful effects of feeding with DFO on the hippocampal tissue.

Sexual function and sexual quality of life in men with genital warts: a cross-sectional study.

BACKGROUND: Human papillomavirus is the most common sexually transmitted infection, usually passing from one person to another after the first sexual activity. Infection with this virus and the occurrence of genital warts (GWs) could have several effects on patients' health. This study was performed to evaluate the sexual function and sexual quality of life (SQOL) in men with GWs. METHODS: This cross-sectional study was conducted from September 2019 to March 2020 with a sample size of 105 men with GWs in the dermatology clinic of Shahid Faghihi Hospital in Shiraz University of Medical Sciences, Iran. Data were collected using a demographic questionnaire, the International Index of Erectile Function (IIEF), and the Sexual Quality of Life-Men (SQOL-M) questionnaires and analyzed by descriptive and inferential tests with SPSS software version 22. RESULTS: The mean score for overall sexual function in men was 48.50 ± 8.89. About 35.2% of men had overall sexual dysfunction (SD). The highest disorder rate was related to the erection domain (85.7%), and the lowest was related to the desire domain (5.7%). In the erection domain, most men (54.3%) experienced mild to moderate erectile dysfunction. The mean score for SQOL-M was 38.36 ± 14.47, and 56.2% of them had a good SQOL. CONCLUSIONS: GWs affected men's erection more than the other sexual function domains. SD in men with GWs has a significant impact on their SQOL and ED was associated with impaired SQOL. Therefore, it is recommended to pay more attention to SD screening alongside SQOL assessment of men with GW.

Human papillomavirus is the most common sexually transmitted infection. Infection with this virus and the occurrence of genital warts (GWs) could have several effects on men and women's health. In this cross-sectional study, we examined the sexual function and sexual quality of life (SQOL) in men with GWs. Of the 105 men, 35.2% had sexual dysfunction (SD). The highest disorder rate was related to the erection domain (85.7%), and the lowest was related to the desire domain (5.7%). In the erection domain, most men (54.3%) experienced mild to moderate erectile dysfunction. 56.2% of them had a good SQOL. SD in men with GWs has a significant impact on their SQOL. Therefore, it is recommended that assessment of sexual function and SQOL should be done when men with GWs refer to health services.

Optimization of physical properties of new gluten-free cake based on apple pomace powder using starch and xanthan gum.

Apple pomace is a valuable waste from the apple juice industry with high level of poly phenols and also phytate-free dietary fiber. This research was done to optimize and compare the physical properties of new gluten-free cake based on whole replacement of wheat flour with apple pomace powder using starch and xanthan gum by Mixture Design. The results of chemical analysis of apple pomace flour showed 10% moisture, 1.28% ash, 1.68% fat, 1.25% protein, 56% fiber and 9.62 mg gallic acid/g phenolic compounds. There was a significant difference in the texture of optimized apple pomace cakes in comparison to rice and wheat cakes as control and black samples. The hardness of the wheat flour sample was less than the gluten-free samples. Based on the results of the sensory evaluation, the cake containing apple pomace powder had the highest score in terms of overall acceptance.

Additional cytogenetic aberrations in chronic myeloid leukemia: a single-center experience in the Middle East

BACKGROUND: Additional cytogenetic aberrations are associated with disease progression in chronic myeloid leukemia (CML). This study was conducted to determine the type and frequency of these aberrations and their relationship with hematologic and molecular findings in the Middle East. METHODS: In this retrospective study, 134 well-established cases of CML were selected from 2010 to 2016. Their hematologic phase and type of fusion gene were determined. Finally, their karyotypes were analyzed and reported according to ISCN 2013. RESULTS: Patients had a mean age of 44 years. Twenty-two patients (16.4%) showed additional cytogenetic aberrations. Nine patients (6.7%) harbored a variant Philadelphia chromosome, and most were in the chronic phase. Seventeen patients (12.7%) had major and minor route abnormalities. There was a significant relationship between additional cytogenetic aberrations and major molecular response (P=0.032). Patient survival in the group with additional cytogenetic aberrations was significantly lower (49.7±11.1 mo) than that in the group without additional cytogenetic aberrations (77.3±3.1 mo) (P=0.031). CONCLUSION: This study revealed the same frequency of additional cytogenetic aberrations in CML as found in previous studies. Additional chromosomal aberrations led to shorter survival and lower rates of achievement of a major molecular response.

The complex associations among sleep quality, anxiety-depression, and quality of life in patients with extreme obesity.

INTRODUCTION: Sleep duration and quality have been associated with obesity. Sleep disturbance has been reported to be associated with stress and depression among non-obese populations, but these relationships have not been previously examined in the obese population. The objective of the current study was to examine the complex associations among sleep disturbance, quality of life, anxiety, and depression in a patient sample with severe obesity. METHODS: Two hundred seventy consecutively recruited patients with a mean body mass index (BMI) of 47.0 kg/m² were studied. The correlation coefficient, multiple linear regressions, and structural equation modeling (SEM) analysis were used to evaluate the association between the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Impact of Weight on Quality of Life-Lite (IWQOL-Lite) and Hospital Anxiety and Depression Scale (HADS). RESULTS: The mean (standard deviation; SD) PSQI score was 8.59 (5.11), and mean ESS score was 8.84 (5.79). After controlling for potential confounders, poor sleep quality and excessive daytime sleepiness were found to be significantly associated of all the components of IWQOL-Lite; physical function (ß = -0.32, ß = -0.27; P < 0.01), self-esteem (ß = -0.23, ß = -0.30; P < 0.05), sexual-life (ß = -0.30, ß = -0.35; P < 0.05), public distress (ß = -0.39, ß = -0.39; P < 0.01), and work (ß = -0.26, ß = -0.48; P < 0.01). We also found that the PSQI global score had a positive significant association with anxiety (ß = 0.29; P = 0.01) and depression (ß = 0.31; P = 0.01) components of HADS. CONCLUSION: Poor sleep quality was strongly associated with mood disturbance and poor quality of life among extremely obese patients. Future interventions are needed to address sleep disturbance to prevent further development of psychological co-morbidity and potentially worsening of obesity among these individuals.

Effectiveness of lifestyle interventions on obstructive sleep apnea (OSA): systematic review and meta-analysis.

BACKGROUND: Obstructive sleep apnea (OSA) is a common sleep disorder associated with several adverse health outcomes. Given the close association between OSA and obesity, lifestyle and dietary interventions are commonly recommended to patients, but the evidence for their impact on OSA has not been systematically examined. OBJECTIVES: To conduct a systematic review and meta-analysis to assess the impact of weight loss through diet and physical activity on measures of OSA: apnea-hypopnea index (AHI) and oxygen desaturation index of 4% (ODI4). METHODS: A systematic search was performed to identify publications using Medline (1948-2011 week 40), EMBASE (from 1988-2011 week 40), and CINAHL (from 1982-2011 week 40). The inverse variance method was used to weight studies and the random effects model was used to analyze data. RESULTS: Seven randomized controlled trials (519 participants) showed that weight reduction programs were associated with a decrease in AHI (-6.04 events/h [95% confidence interval -11.18, -0.90]) with substantial heterogeneity between studies (I(2) = 86%). Nine uncontrolled before-after studies (250 participants) showed a significant decrease in AHI (-12.26 events/h [95% confidence interval -18.51, -6.02]). Four uncontrolled before-after studies (97 participants) with ODI4 as outcome also showed a significant decrease in ODI4 (-18.91 episodes/h [95% confidence interval -23.40, -14.43]). CONCLUSIONS: Published evidence suggests that weight loss through lifestyle and dietary interventions results in improvements in obstructive sleep apnea parameters, but is insufficient to normalize them. The changes in obstructive sleep apnea parameters could, however, be clinically relevant in some patients by reducing obstructive sleep apnea severity. These promising preliminary results need confirmation through larger randomized studies including more intensive weight loss approaches.
