As the age-related impairment of memory and executive functions is associated with decrease in inhibitory control, we investigated age-related inhibition effect after computer-based measuring and free self-determined program of these functions training in groups of younger and older adults. The findings demonstrate training-induced more slowly improvement of both memory and mental speed as well as reduced the inhibition-deficit in older than younger adults. Independently from age, different implicitly created strategies of remembering by retrieval-induced forgetting or forward effect of testing was revealed. Cognitive training induced the increased memory retrieval in younger with dominated forward effect of testing but in the seniors with pronounced inhibition function. So, computerized memory training differently stimulates cognitive reserves due to learning effect in younger and restored inhibition in older adults.","PeriodicalId":230439,"journal":{"name":"2018 11th International Multiconference Bioinformatics of Genome Regulation and Structure\\Systems Biology (BGRS\\SB)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134532478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: We observed 125 patients, including 82 ones with obesity, and 30 lean non-diabetic individuals. The concentrations of leptin, resistin, visfatin, adipsin, and adiponectin in the fasting serum were determined by Multiplex analysis. The fat mass and AT distribution was assessed by DEXA. The samples of subcutaneous abdominal AT were obtained with the knife biopsy in 25 patients and in 15 healthy subjects. Immunohistochemistry for biomarkers CD-34, podoplanin and LYVE-1 was applied to identify the blood and lymphatic microvessels. Results: Patients with diabetes, as compared to control, had significantly higher levels of leptin (p=0.004), resistin (p<0.0001), adipsin (p<0.0001) and visfatin (p=0.0003). The concentrations of leptin, resistin and adipsin were associated with total fat mass. The levels of resistin and adiponectin demonstrated relationships with truncal and central abdominal fat mass. The increase in leptin levels in patients with type 2 diabetes and obesity was associated with a decrease in the volume and numeral density of the blood and lymph microvessels in the subcutaneous fat (r=-0.63, p=0.02; r=-0.55, p=0.05). The level of resistin was negatively correlated with the numeral density of lymphatic vessels (r=-0.59, p=0.03).

Yet, the neural mechanisms underlying association between cognitive training and creativity is poorly understood. It has been reasoned that in young adults right cortex is more engaged in creative ideation. At the same time, right hemisphere is shown to be more affected by aging than left one. There are some reasons, that mental stimulation is effective in maintaining of functional productivity of the aging left hemisphere. We tested if index of EEG alpha asymmetry during divergent thinking and lateral characteristics of verbal memory may be considered as indicator of creative productivity in the elderly. 84 elderly mentally healthy adults participated in the study (43 were engaged in professional scientific activity). Laterality of verbal memory was assessed by dichotic test. EEG data were recorded while subjects were engaged in verbal divergent thinking test. ANOVA, regression and correlation analysis were used. Interhemispheric asymmetry in task-related alpha desynchronization with larger values in the right hemisphere was associated with the strength of right hemispheric strategies of verbal memory. This effect was related to low creative originality in elderly engaged in professional scientific activity. The results suggest that life-long mental stimulation could be responsible for additional involvement of the left-hemispheric strategies to enhance creative efficiency in the elderly. The study showed that the combination of psychometric and EEG methods of interhemispheric asymmetry assessment is a functional approach for objective investigation of creative capacity of the aging brain.","PeriodicalId":230439,"journal":{"name":"2018 11th International Multiconference Bioinformatics of Genome Regulation and Structure\\Systems Biology (BGRS\\SB)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133938632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These doses were calculated based on lithium containing at the ratio 5,6 mg/kg. Pharmacokinetic parameters and relative bioavailability were calculated based on lithium ions concentration in serum and brain, which was measured by inductively-coupled plasma atomic emission spectrometry (ICP-AES). According to received pharmacological data of LCAS the Cmax of lithium ions in serum is lower by 4,3 times, than if administration of LC, relative bioavailability of LCAS is 44.41% of standard LC.
