The real-time signals of alternating-current (ac) magnetic susceptibility, χac, of the reagent are subsequently recorded after mixing the reagent with a biofluid sample. After mixing the reagent and sample, the reduction in χac of the mixture is calculated and used to quantify the concentration of the target biomarker in the sample. The reduction does not occur immediately but rather occurs at some time after mixing. This observation implies that the time elapsed before recording the real-time signals of χac of a reagent-sample mixture needs to be investigated to ensure that the signals are fully recorded. In this work, the effect of time to detection on the measured concentrations of proteins in human plasma after mixing the reagent and sample is examined. Methods: The proteins analyzed are related to Alzheimer’s disease: amyloid β 1–40, amyloid β 1–42, and Tau protein. The investigated times to detection after the mixing the reagent and sample are 0, 20, 30, 40, and 120 min. Results: The results show that the recording of real-time signals of χac should be conducted within 20 min after mixing the reagent and sample.","PeriodicalId":38017,"journal":{"name":"Dementia and Geriatric Cognitive Disorders Extra","volume":"12 1","pages":"82 - 89"},"PeriodicalIF":2.3,"publicationDate":"2022-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45674099","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}

It has also been pointed out that AD associated with DM may have unique characteristics. However, the characteristics of impairment in daily functioning when associated with DM have not been sufficiently investigated. Methods: In the present study, we compared the characteristics of 261 patients with AD diagnosed in the outpatient memory clinic of a university hospital, divided into diabetic and nondiabetic groups. The MMSE was used to assess cognitive function, and the Dementia Assessment Sheet for Community-based Integrated Care System 21-items (DASC-21) was used as an observational method to assess cognitive function and activities of daily livings. The two groups were compared. Furthermore, simple and multiple regression analysis was carried out in order to find the independent association of age, sex, education, DM, and HbA1c with the DASC-21 and each individual item of the DASC-21. Results: Diabetic subjects were as follows: MMSE 18.8 ± 4.0, DASC-21 46.0 ± 13.2, and HbA1c 7.07 ± 1.24%, respectively. On the other hand, nondiabetic subjects were as follows: MMSE 19.0 ± 4.5 and DASC-21 42.1 ± 12.2, respectively. In the diabetic group, total score of DASC-21 was higher (DM vs. nondiabetes mellitus [NDM]: 46.0 ± 13.2 vs. 42.1 ± 12.2; p < 0.05) and solving issues and common sense on the DASC-21 were higher than in the nondiabetic group (NDM) (DM vs. NDM: 8.58 ± 2.71 vs. 7.76 ± 2.66; p < 0.05).

Methods: Scopolamine (1 mg/kg, intraperitoneal [i.p.]) was used for induction of memory impairment. The animals received various doses of dapsone (0.1, 0.3, 1, 5, and 10 mg/kg, i.p.). Duration and number of arms visits in the Y-maze and step-through latency in the passive-avoidance were documented. To evaluate the underlying signaling pathway, N(ω)-nitro-L-arginine methyl ester (a nonspecific NO synthase [NOS] inhibitor), aminoguanidine (a specific inducible NOS inhibitor), and 7-nitroindazole (a specific neuronal NOS inhibitor) were administered 30 min after dapsone administration. Results: Dapsone (5 mg/kg) substantially improved memory acquisition in scopolamine-induced memory impairment. Additionally, NOS inhibitors considerably reversed the observed neuroprotective effects of dapsone, accompanied by the elevation of NO levels.

Moreover, the multiple regression analysis showed that the predictor of the greatest effect for domestic and complex domains was dominant hand dexterity. Discussion/Conclusion: These results revealed that dominant hand dexterity strongly affected domestic and complex ADL in older adults with MCI.

Our objective was to discern whether elevated alcohol consumption is associated with TSA. Methods: Alcohol consumption was measured among 3,236 older Norwegians assessed for cognitive impairment. Elevated consumption was defined as drinking 4–7 times a week. TSA was defined as the number of months between symptom debut and assessment. The association between alcohol consumption and TSA was examined with a multiple regression analysis controlled for sociodemographic and clinical covariates. Results: Mean (SD) and median TSA were 34.8 (35.8) and 24.0 months, respectively. Elevated alcohol consumption was not associated with TSA. Longer TSA was associated with being male, having a high education level, being retired or unemployed, being single, having low scores on the Mini-Mental State Examination (MMSE) or Personal Activities of Daily Living (PADL), having high subsyndrome scores of depression or agitation on The Neuropsychiatric Inventory – Questionnaire (NPI-Q), or having a spouse/cohabitant as the designated next of kin. Conclusion: This study indicates that elevated alcohol consumption does not influence TSA. Possible explanations are discussed, but further research is needed to determine the effect of alcohol definitively. We did identify other novel characteristics associated with TSA which may be important in minimizing the risk of delayed cognitive assessments and should be kept in mind when considering assessment.","PeriodicalId":38017,"journal":{"name":"Dementia and Geriatric Cognitive Disorders Extra","volume":"12 1","pages":"14 - 23"},"PeriodicalIF":2.3,"publicationDate":"2022-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47109298","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}
