Effect of temperature and photoperiod on reproductive behavior of corn stem borer, Sesamia cretica (Lederer, 1857) (Lep.: Noctuidae)

The corn stem borer, Sesamia cretica Led. (Lep.: Noctuidae),is the most important pest of maize and sugarcane throughout the world including Iran where its egg parasitoid wasp, Telenomus busseolae Gahan (Hym.: Scelionidae) is widely used in biological control programs. Due to the host specificity of the parasitoid wasp, S. cretica serves as the single host for the mass rearing of T. busseolae at the laboratory or insectarium. The present work was intended to find the optimum temperature and photoperiod for the reproductivity of S. cretica at laboratory condition. We evaluated the percentage of fertilized eggs, oviposition rate, peak of egg laying and adult longevity of S. cretica. Thermal treatments and photoperiod treatments included 24, 27 and 30 ºC as well as 24D, 12D: 12L, 8L: 16D (short day period), 16L:8D (long day period) hours respectively. The best temperature for oviposition was calculated between 24 and 27 ºC, but the rate of oviposition was significantly decreased at 30 ºC. Temperature and photoperiod had no effect on the percentage of fertilized eggs and adult longevity. Different photoperiods caused significant effect on the rate of oviposition and the highest oviposition rate occurred in 12L: 12D hours and in 16D:8L hours. The lowest rate of oviposition was observed in 24D period. The highest rate of oviposition occurred on the second day

Effects of whole body vibration on concentric torque of ankle invertor and evertor muscles in people with functional ankle instability

Introduction: Changes in invertor and evertor muscle torque is one of the sensory-motor disabilities along with functional ankle instability (FAI). According to positive advantages of whole body vibration (WBV) on muscle torque, this study has been conducted to evaluate the effect of WBV on evertor to invertor muscle concentric ratio in people with FAI. Materials and Methods: 30 female with FAI assigned randomly into experimental and control groups. The experimental group received 6 weeks WBV (3 times per weeks). Then they were evaluated according to their evertor and invertor muscle concent ric torque. Concentric muscle torque was evaluated by Biodex Isokinetic. Results: There were no significant differences between concentric torque of evertor and invertor muscles (P> 0.05). WBV could improve concentric torque of invertor and evertor muscles in the ankle of people with FAI (P< 0.05). Conclusion: 6 weeks WBV (18 sessions) can increase concentric torque of evertor and invertor muscles in people with FAI. � 2016, Semnan University of Medical Sciences. All Rights Reserved

Comparison of patient�s kidney function based on kidney disease improving global outcomes (Kdigo) criteria and clinical parameters in isolated coronary artery bypass graft (cabg) surgery in on-pump and off-pump methods in patients with low cardiac output syndrome (lcos) after surgery

Background: Acute kidney injury (AKI) is one of the serious complications of cardiac surgery. It is worsened when accompanied by low cardiac output syndrome. Objectives: In this study, we compared kidney function based on the KDIGO criteria in isolated on-pump and off-pump coronary artery bypass graft (CABG) surgery. Methods: In this cohort study, 52 patients with LCOS were enrolled after on-pump (28 patients) and off-pump (24 patients) CABG. In the first six hours after ICU entrance, blood samples were taken for serum creatinine based on routine. For determining AKI after surgery, we used the KDIGO criteria as a primary endpoint. Also, some clinical parameters were recorded before, during, and after surgery. The data were analyzed by SPSS software, version 24, using paired and independent t-test, ANOVA, and Pearson correlation test and non-parametric tests such as Mann-Whitney and Kruskal-Wallis tests at a significance level of P < 0.05. Results: There was no significant difference in age (P = 0.3) and gender (P = 0.57) between the two groups. Among cardiac disease risk factors, only hypertension (P = 0.02) had a significant difference between the two groups, but AKI in patients with hypertension did not show a significant difference (P = 0.09). In paraclinical parameters, serum creatinine showed a significant difference before and after surgery in on-pump (P < 0.001) and off-pump (P = 0.007) groups. Also, this parameter had a significant difference at 6 h, 12 h, 24 h, and 48 h after surgery between the on-pump and on-pump groups. The AKI incidence showed a significant difference between the two groups (P < 0.001). Conclusions: The incidence of AKI was more in on-pump patients than in off-pump patients. Also, a significant difference was observed between their clinical parameters. Thus, to improve the patients� clinical outcomes and lower the health costs, we suggest that patients with a high risk of LCOS be followed up after CABG, especially on-pump CABG. © 2020, Author(s)

The effect of QEEG- guided neurofeedback treatment in decreasing of OCD symptoms

AbstractThe main purpose of this research is to determine effectiveness of QEEG- Guided Neurofeedback therapy in decreasing OCD symptoms. Twelve patients were selected from Atiyeh institution in Tehran- Iran and they are placed in 3 situations randomly which are neurofeedback, drug therapy and waiting list. Padua Inventory is administered for all patients as pre- test and post- test in 10 weeks. The results of this research using kuruskal – Wallis and Mann-whitney U test were analysed. It's resulted that neurofeedback treatment may be used as a new treatment approach for treating OCD

Determination of blood glucose lowering and metabolic effects of Mespilus germanica L. extract on normal and streptozocin-induced diabetic Balb/c mices

Background and objectives: The serum glucose lowering, normalization animal body weight and antioxidative stress effects of Mespilus germanica L. leaf extract were investigated in normal and streptozotocin-induced Balb/C mices. Methods: The leaves of M. germanica were extracted using acetone/water (70:30) by percolation method and concentrated using rotary-evaporator device and its total phenolics and flavonoids content were determined using Folin-Ciocalteu and aluminum chloride methods, respectively. The study was conducted on forty eight matured male Balb/C mices (20-30 g) divided into 6 groups (n=8). Diabetes mellitus was induced by single intraperitoneal injection of 35 mg/kg of streptozotocin (STZ). Extracts of Mespilus germanica were used orally at the dose of 50, 100 and 200 mg/kg body weight per day for 21 days. Results: Oral administrations of the Mespilus germanica L. leaf extract significantly decreased serum glucose, oxidative stress and lipid peroxidation and maintained animal body weight during treatment period (

Surveying Effectiveness of Neuro-feedback in Reduction of Attention and Concentration Deficit Symptoms in ADHD Adults

ADHD is one of common neuropsychological disorders in childhood and continuing to adulthood and disturbs various dimensions of individual’s life such as personal affairs, social interactions, professional life, executive performance like active memory and concentration etc. There are numerous works on treatment of this type of disorder. Considering the lack of studies on neuro-feedback in adults, this research was conducted. For this purpose, this survey tries to determine effectiveness of neuro feedback in reduction of attention and concentration deficit symptoms in ADHD adults. This is experimental research pre-test and post-test as well as control group. Statistical population includes adults with ADHD referring to Atiye Clinic in Tehran. Two groups of experimental and control, each one composed of 8 people, were selected using purposive sampling. Research tools were Beck Stress Questionnaire, Beck Depression Questionnaire, Barkely Adults ADHD Questionnaire, IVA Test, and CNSVS test. The data were analyzed using SPSS software and Mann Whitney statistical test. Also, independent t-test, Wilcoxon, and Kruskal Wallis were applied for further results. Findings showed that neuro-feedback significantly reduced attention and concentration deficit symptoms in ADHD adult experimental group compared to control one. Therefore, neuro-feedback could be suggested for reduction of attention deficit symptoms and reduction of ADHD in adults
