Neuro-cognitive Ramifications of Fasting and Feeding in Obese and Non-obese Cases
Seyed-Ali Mostafavi,Ali Khaleghi,Safa Rafieivand,Seyyed Salman Alavi,Mohammad Reza Mohammadi 대한정신약물학회 2018 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.16 No.4
Preliminary studies have claimed that short term fasting would negatively affect school performance and cognition. In contrast some other studies have reported not important decline in cognition and executive function as a result of fasting. Also limited attention was generally devoted to dietetic regimens, nutritional status and body weight. Yet neuroscience and neuro-cognitive aspects of acute hunger on the electroencephalogram and differences between obese and non-obese cases is not well understood. Hence, we decided to design and perform a case study in a more controlled situation similar to reality. Therefore, we performed several examinations including subjective tests (for eating status) and objective tests (cognitive tests such as Stroop effect and Sternberg search and electroencephalogram measures such as steady-state visual evoked potential and auditory steady-state responses) for an obese and a non-obese academic case before and after a simple breakfast. The results showed that the breakfast effects on the neuro-cognitive functions depend on either obesity status, nutritional status of the case or the type of cognitive task (visual or auditory). This paper would open a new insight to answer some important questions about the neuro-cognitive implications of fasting and feeding in obese and non-obese human cases.

Genotype × environment interaction is one of the complex issues of breeding programs to produce high-yielding and compatible cultivars. Interaction of genotype × environment and make the more accurate selection, the performance and stability of hybrids need to be considered simultaneously. This study aimed to investigate stable genotypes with yield using 12 maize hybrids in different climatic conditions of Iran. The experimental design used was a randomized complete blocks design in three replications in two cropping years in Karaj, Birjand, Shiraz, and Arak stations. The simple analysis of variance performed on grain yield of genotypes indicated that all hybrids studied each year and station were significantly different in grain yield. Also, the combined analysis results showed a significant effect on the environment, the effects of genotype, and the interaction of genotype × environment and t in the studied hybrids different. Comparing Duncan's mean on the data obtained from the research, KSC705 genotypes with an average yield of 7.21 and KSC704 genotype with an average yield of 7.04 were identified as high yield cultivars. In order to identify stable cultivars, six stability parameters were used. KSC260 and KSC707 genotypes had stability Based on the environmental variance, also had stability based KSC705, KSC707 genotype on environmental the coefficient of variation, and KSC260 genotypes had stability based methods of genotype and environment interaction. As well as based on Eberhart and Russell regression coefficient had the stability to KSC400 and SC647 genotypes. Also, they were identified as the most stable genotypes based on the detection coefficient method, KSC707, and KSC703 genotypes.

Background and Objective Co-morbidity of obesity, sleep disturbance, and depression is common, especially among women. We aimed to evaluate the effects of melatonin on body weight, depression symptoms and sleep among women with co-morbidities of obesity, mild and moderate depression, and sleep disturbances seeking weight reduction compared with the placebo.Methods This double-blind, randomized clinical trial was performed on 43 patients with comorbidity of mild and moderate depression, overweight/obesity (body mass index ≥ 25) and sleep disturbance. After obtaining the informed consent forms they were randomly assigned to receive 3 mg melatonin or placebo at bed-time. We performed body composition assessments, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory and Pittsburgh Sleep Quality Index at the baseline, and 2, 4, 8, and 12 weeks after initiating of the study. We analyzed the data using analysis of variance repeated measures.Results Melatonin significantly reduced depression symptoms compared with the placebo, F = (1, 34) = 6.2, p = 0.017. Also, melatonin significantly improved sleep quality, F = (1, 33) = 8.0, p = 0.008. Besides, subjects on the melatonin reduced more weight compared with the placebo but difference between groups was not significant, F = (1, 41) = 0.2, p = 0.650. Patients in the melatonin group did not show significantly more side effects compared to placebo.Conclusions Based on our findings, melatonin was not able to significantly reduce the body weight more than placebo, but as a safe over-the-counter supplement, it may be helpful in patients with co-morbidities of sleep disturbance, mild and moderate depression, and obesity in reducing the symptoms of depression and insomnia.
