Amaç: Elektrolit ölçümleri, klinik biyokimya laboratuvarlarında yapılan rutin testlerin vazgeçilmez bir parçasıdır. Bu çalışmada, serum sodyum (Na), potasyum (K) ve klor (Cl) elektrolitleri iyon seçici elektrot (ISE) yöntemi ile ölçülmüş ve doğrusallık, kesinlik, tekrarlanabilirlik ve doğruluk seviyeleri Mindray BS-800M ve Beckman Coulter AU5800 cihazlarında değerlendirilmesi amaçlanmaktadır.Gereç ve yöntem: Serum örnekleri, Ocak-Nisan 2021 tarihleri arasında Karapınar Devlet Hastanesi'ne kontrol amaçlı başvuran sağlıklı gönüllülerden alınmıştır. Örnek probu, ISE yöntemi için ayrı bir numune probu olup Mindray BS-800M ve Beckman Coulter AU5800 cihazlarında indirekt yöntem kullanılarak gerçekleştirilmiştir.Bulgular: Karşılaştırmalı ölçümler farklı cihazlarda yapılırken elektrolitler arasındaki korelasyonlar Na [r=0,964, % 95 CI (0,52-0,90)], K [r=0,995, % 95 CI (0,09-) 0.12)] ve Cl [r=0.972, % 95 CI (0.69-1.12)] olarak bulundu. Ayrıca bu sonuçlar arasında da bir korelasyon belirlenmiştir.Sonuç: Farklı analizörlerde ölçülen Na, K ve Cl elektrolitleri arasında bir tutarlılık belirlendi. Ayrıca, bu elektrolitler arasında pozitif bir korelasyon bulunmaktadır. Bu sonuçların açıklığa kavuşturulması için daha fazla ve kapsamlı çalışmalara ihtiyaç olduğu görülmektedir., Objective: The measurements of electrolytes are an indispensable part of the routine tests performed in clinical biochemistry laboratories. In the present study, we aimed to measure serum sodium (Na), potassium (K), and chlorine (Cl) electrolytes via the ion-selective electrode (ISE) method and evaluated in terms of linearity, precision, repeatability, and accuracy levels in the Mindray BS-800M and Beckman Coulter AU5800 devices.Material and methods: The serum samples were obtained from the healthy volunteers admitted to the Karapınar State Hospital for control purposes between January and April 2021. The sample probe was conducted using the same indirect method in the Mindray BS-800M and Beckman Coulter AU5800 devices, which is an individual sample probe for the ISE method.Results: While the comparative measurements were performed on different devices, the correlations between the electrolytes were found as follows: Na [r=0.964, 95% CI (0.52-0.90)], K [r=0.995, 95% CI (0.09-0.12)], and Cl [r=0.972, 95% CI (0.69-1.12)]. Moreover, a correlation was also found between these results.Conclusion: A consistency between the measured Na, K, and Cl electrolytes was determined on the different analyzers. Also, a positive correlation was determined between those electrolytes. We consider that further and comprehensive studies are needed to elucidate these results.

Congress of the Pan-Asian-Committee-for-Treatment-and-Research-in-Multiple-Sclerosis (PACTRIMS) -- 2018 -- Sydney, AUSTRALIA, WOS: 000460691800073, Background: Optical Coherence Tomography (OCT) is an improved technique in the last 20 years that allows quantitative measurement of retinal nerve fiber layer (RNFL) thickness, which provides important information on approach to optic nerve diseases in neurology and ophtalmology area. Therefore, OCT is now being used in various neuro-ophthalmic situations. On the other hand it is known that MS is also involved in a highly complexity of countless biomarkers that are elucitaded an autoimmune disease of the central nervous system. Serum and Cerebrospinal fluid Cytokines, TNF-α, neopterin (a marker of INF-β activity) may play important role in cell swelling, synaptic transmission and neural integration., Pan Asian Comm Treatment & Res Multiple Sclerosis

Syfte: Syftet med denna studie är att undersöka hur ungdomar som tränar upplever att fitness-influencers på YouTube påverkar deras hälsobeteenden. Detta för att på så sätt bidra med kunskap åt samhället om den konkreta effekt som marknadsföringen av träning och kost har på sociala mediekanaler för att börja täcka det forskningsgap som berör hälsorelaterade beteenden. Metod: Vid insamling av empiri användes en kvalitativ metod i form av semi-strukturerade intervjuer. Det empiriska materialet analyserades utifrån det teoretiska ramverket om influencermarknadsföring, parasociala relationer, electronic word-of-mouth och tvåstegshypotesen samt tidigare forskning om hälsobeteenden på sociala medier. Slutsats: Respondenterna påvisade en medvetenhet om den påverkan som influencers har på deras motivation kring hälsa, träning och kost. Majoriteten ser både för- och nackdelar med sociala medieinfluencers då de kan bidra med motivation samtidigt som det framkommer att de även kan leda till minskad motivation. Fitnessinfluencers kan påverka ungdomar till att variera sin kost på ett mer hälsosamt sätt. Det framkommer även att fitness-influencers kan bidra med kunskap inom träning och kost vilket följarna kan ta lärdom av. Det delade innehållet hos fitness-influencers har däremot även visats kunna ha negativa hälsoutfall då det kan leda till upplevd hets för respondenterna. Parasociala relationer är en betydande faktor då följare med dessa relationer till influencers kan se dem som förebilder som kan bidra med motivation och inspiration till mer hälsosamma beteenden. Den påverkan som dessa relationer kan ha är dock inte avgörande, utan det är enligt respondenterna den egna disciplinen som är det viktigaste. Purpose: The purpose of this study is to investigate how adolescents experience that fitness-influencers on YouTube influence their health behaviors. This to contribute knowledge for the society about the concrete effect which the marketing of exercise and diet has on social media platforms regarding bridging the gap related to healthy behaviors. Method: While collecting empirical data, a qualitative method was used in the form of semi-structured interviews. The empirical material was analyzed based on the theoretical framework of influencer marketing, parasocial relationships, electronic word-of-mouth, the two-step flow theory and earlier studies about health behaviors on social media. Conclusions: The respondents demonstrate an awareness of the impact that influencers have on their motivation regarding their health, exercise and diet. The majority see both advantages and disadvantages of social media influencers as they can contribute with motivation at the same time as it emerges that they can also lead to reduced motivation. Fitness influencers can influence young people to a more varied diet in a healthier way. It also appears that fitness influencers can contribute knowledge about health and exercise, which the followers can learn from. However, the shared content of fitness influencers also appears to have negative health outcomes as it can lead to negative body perceptions. Parasocial relationships are a significant factor as followers who experience these relationships with influencers can perceive them as role models who can contribute with motivation and inspiration for healthier behaviors. However, the impact that these relationships can have, is not the most crucial since the own discipline is explained to be the most important factor according to the respondents.

Quasi-orders are reflexive and transitive binary relations and have many applications. Examples are the dependencies of mastery among the problems of a psychological test, or methods such as item tree or Boolean analysis that mine for quasi-orders in empirical data. Data mining techniques are typically tested based on simulation studies with unbiased samples of randomly generated quasi-orders. In this paper, we develop techniques for the approximately representative sampling of quasi-orders. Polynomial regression curves are fitted for the mean and standard deviation of quasi-order size as a function of item number. The resulting regression graphs are seen to be quadratic and linear functions, respectively. The extrapolated values for the mean and standard deviation are used to propose two quasi-order sampling techniques. The discrete method matches these location and scale measures with a transformed discrete distribution directly obtained from the sample. The continuous method uses the normal density function with matched expectation and variance. The quasi-orders are constructed according to the biased randomized doubly inductive construction, however they are resampled to become approximately representative following the matched discrete and continuous distributions. In simulations, we investigate the usefulness of these methods. The location-scale matching approach can cope with very large item sets. Close to representative samples of random quasi-orders are constructed for item numbers up to n = 400.
