The culture of human stem cells shares many of the same standards as mammalian somatic cell culture. Since the cells in culture are exposed to a different environment from the environment of the living body, the cells per se tend to adapt and adapt to the culture conditions. Particularly, they can be easily affected by external pathogen or culture environment because hPSCs are dynamic cells with pluripotency and regeneration ability [1]. In addition, the method of maintaining undifferentiated state during longterm culture without loss of regeneration ability or pluripotency may affect the characteristics of cells resulting in changes of the authenticity, and instability of hPSCs. Qualitative assessments during the culture of hPSCs include purity, viability, morphological appearance, confluency (the percentage of the surface of a culture dish that is covered by adherent cells), functionality, contamination and cross-contamination, authenticity, differentiation state, and identification of genetic stability [1]. Among them, the key elements of cultivation of hPSCs would be authenticity, sterility, and stability of cell lines [1,2].","PeriodicalId":94322,"journal":{"name":"Integrative molecular medicine","volume":"109 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79205709","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}

In addition, publication of such studies is increasingly becoming a component of evidence-based purchase decision making. ISO 15197:2015,2 for which mandatory compliance is recommended for SMBG systems by 2015,3 has tighter accuracy requirements than ISO 15197:2003,4 and outlines current minimum accuracy standards necessary in Europe for CE marking. Introduction In the present study, a post marketing evaluation of the CE-marked GL50 evo and GL44 systems were performed in accordance with ISO 15197:2015 protocols and requirements. The GL50 evo and GL44 systems were supplied in Germany from the Beurer GmbH, Germany. A declaration of conformity from the manufacturer of the two measuring systems was available before the start of the study, so that only the GL50 evo was used in the tests, but the results documented the quality of both systems. Two GL50 evo systems (serial number: GL55 T1 and GL55 T2) and strips from 3 different lots (A 10/1, A 10/3, A 10/4) with expiry dates March 2017 respectively) were supplied by the manufacturer. The study was conducted from April 21 to May 05, 2015, at the Institute of Diabetes “Gerhardt Katsch,” Karlsburg, Germany. Ethical approval for the study was obtained from the Ethics Committee of the University of Greifswald in July 2014 [1-3]. Ear lobe capillary blood samples were taken from 118 subjects for duplicate glucose determination using the GL50 evo and the glucose oxidase based YSI2300 STAT PLUS (YSI Incorporated, Yellow Springs, Ohio, USA) plasma glucose reference method. Trueness and precision of the comparison assay were verified using a range of YSI bioanalytical standards and controls. The prescribed limits for the hematocrit values, to be between 20% and 60%, were reached by the patient samples and after examination of glucose concentration ranges using the YSI, 100 subjects were included in the analysis of accuracy [4]. In the glucose range <100 mg/dL in summary 98.8 % of the values and in the range ≥ 100 mg/dl in summary 98.6 % full filled the quality criteria of the ISO 15197.

The electroencephalogram (EEG) is one of the most widely-used instruments for the non-invasive neuro-physiological measure of brain function and health. The EEG was originally used to solely monitor and record electric waves generated by electrical activity in the brain to aid in clinical decision-making and diagnosis. Technological improvements have made it possible for state-of the-art EEG computer-based systems like NeuralScan by Medeia Inc. to evaluate changes in power and in ratios of these brain waves with changes in brain and mental health status. Today’s EEG machines can also identifying the precise localization of these changes enabling more accurate diagnosis and treatment. Improvements in EEG technology have made them robust, stationary/portable, high fidelity, versatile with the ability to carry out complex functions and calculations yet still be user/clinician-friendly highlighting their potential for use in clinical, research, epidemiological and public health settings. The present article presents an overview on EEG machines, their use in diagnosis, prognosis and therapy and to generate EEG-based markers in the area of cognition, mental and brain health. Introduction EEG in brain health and cognition Normal functioning of the cerebral cortex is critical to physiological, neurological and mental health. Currently, cognitive, mental, neurological, and substance-use diseases/disorders account for 258 million disability adjusted life years (10.4% total all cause DALYS). This reiterates the need for better prevention, diagnostic and treatment options for brain health that can be used in clinical, epidemiological and public health settings [1-2]. Among the diagnostic and assessment tools for brain health are the a) non-invasive: neuro-clinical-physical examinations, questionnaires /instruments, electroencephalogram EEG, neuroimaging including ultrasound, magnetic resonance imaging, MRI, functional MRI (fMRI), positron emission tomography (PET), and computerized tomography (CT); and b) the invasive: biochemical tests, genetic tests, cerebrospinal fluid (CSF) analysis, angiography, and biopsies. While the MRI, fMRI, PET and CT provide good spatial resolution of brain health, the EEG evaluates brain health via temporal resolution of brain function within the millisecond range [3-5], which is not possible with the other approaches. Due to its sensitivity to changes in brain function and structure and its simplicity of use in clinical settings, its use in intensive care has continued to increase in recent years [6-8]. The EEG assesses the neurophysiological aspects of brain function via the capture of the electric waves generated by electrical activity in the cerebral cortex. The cerebral cortex is divided into four lobes: the frontal, parietal, tempora","PeriodicalId":94322,"journal":{"name":"Integrative molecular medicine","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89927194","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}

In view of the action of preventing disease, DFT/MM is undertaken to analyze redox reactions in mitochondria (mt) as battery of cells which is functioning using oxygen and D-glucose. Materials and methods: DFT-based molecular modeling (DFT/MM), equivalent to the quantum mechanics/molecular mechanics (QM/MM) method, was performed by using the B3LYP exchange-correlation function and the 6–31G(d) basis set with Spartan’16 (Wavefunction, Inc. Irvine, CA). Results: DFT/MM verifies and predicts that superoxide radical anion (O2) and hydrogen peroxide (HOOH) are produced by redox reactions of ground state oxygen (O2) and D-glucose in mt. Without exhausting ATP, accumulation of HOOH will start in mt, resulting in production of hazardous hydroxyl radical (HO dot). The hydroxyl radical (HO dot) destroys cellular membrane, leading to dysfunction of mt. Accumulation of HOOH and formation of hazardous HO radical will be suppressed by antioxidative chemical substance, e.g., Vitamin C, thyroxin (T4), and triiodothyronine (T3). Thyroid hormone is one of so-called super oxide dismutase, iodine atoms in which play an important role of antioxidative effects in mt. Conclusion: Dietary intake of antioxidative chemical substance like Vitamin C, preservation of acceptable level of iodine-bearing T4 and T3 in blood, and aerobic exercise which prevents accumulation of HOOH are essential for prolonged mt as battery of cells.","PeriodicalId":94322,"journal":{"name":"Integrative molecular medicine","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72825219","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}
