Abstract The ohmic heating process is one of the novel electrical heating methods that are considered as fast, homogeneous and efficient heating. In this study, the details of the relationship between electrical conductivity (EC)-Temperature (Temp) and EC-pH-Temp at different Total Soluble Solid Content (TSSC) and different pH values were examined. Especially, the study explains details of the electrical conductivity value due to pH change (2, 2.5, 3, 3.5) and expressing EC change depending on the pH value of fruit and vegetable juices. At constant pH, EC values decrease with increasing TSSC values (10%, 20%, 30%, 40%, 50%, 60%) and decrease with increasing pH at constant TSSC value. When the relationship between Temp-EC is analyzed that the EC value increases as Temp increases in all cases and this increase is linear. It was found that the Temp-EC relationship was in high compatibility with an R2 value above 0.97. Also, in the Temp-EC-pH relationship, the R2 value was found to be an acceptable value above 0.95. fast ECTemperature Temperature (Temp ECpHTemp (TSSC examined Especially 2, 2 (2 25 5 2.5 3 3.5 35 juices 10%, 10 (10% 20 20% 30 30% 40 40% 50 50% 60% 60 TempEC linear R 097 0 97 0.97 Also TempECpH 095 95 0.95 ( 2. 3. 10% 1 (10 4 6 09 9 0.9 (1 0.

SUMMARY OBJECTIVE: There are limited data about the significance of erythrocyte sedimentation rate as a single prognostic parameter for the prognosis and mortality of COVID-19. This study aimed to investigate the diagnostic utility of erythrocyte sedimentation rate as a prognostic factor for the disease severity and mortality in patients with COVID-19. METHODS: A total of 148 consecutive patients with a confirmed diagnosis of COVID-19 and hospitalized at the intensive care unit or non-the intensive care unit were included in the study. The patients were allocated to groups as severe/critical disease versus nonsevere disease and survivors and nonsurvivors. The prognostic role and predictable values of erythrocyte sedimentation rate were analyzed. RESULTS: Erythrocyte sedimentation rate was found to be higher among patients with severe/critical disease compared to those with nonsevere disease (p<0.001) and among nonsurvivors compared to survivors (p<0.001). The logistic regression analysis showed that erythrocyte sedimentation rate was an independent parameter for predicting disease severity and mortality. The role of erythrocyte sedimentation rate in the assessment of severity and mortality in patients with COVID-19 was analyzed using the receiver operating characteristic curve and was found to be significant in both. The analyses suggested that the optimum erythrocyte sedimentation rate cutoff point for disease severity and mortality were 52.5 mm/h with 65.5% sensitivity and 76.3% specificity and 56.5 mm/h with 66.7% sensitivity and 72.5% specificity. CONCLUSION: Our results suggest that erythrocyte sedimentation rate was an independent prognostic factor for severity and mortality in patients with COVID-19.

Abstract Mirabegron is the first b3-adrenoceptor agonist to enter clinical practice and has been approved for the treatment of symptoms of OAB. The aim of this study is to investigate whether the mirabegron has an effect on depression, anxiety, learning, and memory. We investigated the effects of mirabegron on depression, anxiety, learning and memory by using forced swimming test, elevated plus maze test, passive avoidance and Morris water maze in mice. Imipramine and mirabegron (3, 6 and 9 mg/kg) significantly reduced immobility time in forced swimming test. Diazepam and mirabegron (3, 6 and 9 mg/kg) significantly increased the time spent in open arms and the number of entries to the open arms in elevated plus maze test. Furthermore, cognitive performance impaired with scopolamine has been significantly improved with 9 mg/kg mirabegron. Mirabegron (6 and 9 mg/kg) significantly increased the time spent in the target quadrant in naive mice. While scopolamine significantly increased the swimming speed, mirabegron (9 mg/kg) significantly decreased the swimming speed in scopolamine-treated mice. Mirabegron might be clinically useful for the treatment of OAB in elderly patients that should use drugs against depression and anxiety, without disrupt learning and memory.

RESUMO Objetivo: Este estudo foi realizado para avaliar a relação entre a interrupção da junção segmento interno/segmento externo (IS/OS), espessura macular e grau de membrana epirretiniana (ERM), com a melhor acuidade visual corrigida (BCVA), e a relação entre a interrupção da junção IS/OS com a severidade da ERM. Métodos: Cinquenta e quatro olhos de 54 pacientes com diferentes graus de ERM foram avaliados retrospectivamente. ERMs foram classificadas, de acordo com as estrias de retina e a distorção dos vasos, em 3 grupos: grupo 1 foram membranas visíveis sem estrias retinianas ou distorção dos vasos, grupo 2 membranas com estrias maculares discretas a moderadas ou retificação dos vasos, e grupo 3 membranas com estrias moderadas a graves e retificação vascular. A correlação da BCVA com a idade, espessura central da retina, severidade da ERM e interrupção da junção IS/OS foram avaliadas. A relação de interrupção da junção IS/OS, a espessura macular central e acuidade visual com a severidade da ERM também foram avaliadas. Resultados: Vinte e nove olhos (53,7%) apresentavam interrupção da junção IS/OS. A BCVA foi diferente entre ERMs grupo 1 e grupo 2 (p=0,038), a diferença entre o grupos 2 e 3 não foi estatisticamente significativa (p=0,070). A espessura macular central foi estatisticamente maior no grupo 2, quando comparado ao grupo 1 (p=0,031) e maior no grupo 3 quando comparado ao grupo 2 (p=0,033). A diferença entre o grupo 1 e grupo 2 em relação à interrupção da junção IS/OS foi estatisticamente significativa (p=0,000), ao passo que a diferença entre o grupo 2 e do grupo 3 não foi estatisticamente significativa (p=0,310). Conclusões: As junções IS/OS parecem estar interrompidas nos estágios iniciais da ERM. O grau 3 de ERM têm uma maior incidência significativa de interrupção da junção IS/OS.

ABSTRACT Purpose: This study was conducted to evaluate the relationships of inner/outer segment (IS/OS) junction disruption, macular thickness, and epiretinal membrane (ERM) grade with best-corrected visual acuity (BCVA), as well as the relationship between IS/OS junction disruption and ERM grade. Methods: Fifty-four eyes of 54 patients with different grades of ERM were retrospectively reviewed. Patients were classified into three groups by ERM grade according to retinal striae and vessel distortion: grade/group 1, visible membranes without retinal striae or vessel distortion; grade/group 2, mild to moderate macular striae or vessel straightening; and grade/group 3, moderate to severe striae and vascular straightening. Correlations of BCVA with age, central retinal thickness, ERM grade, and IS/OS disruption as well as of IS/OS disruption, central macular thickness, and BCVA with ERM grade were evaluated. Results: Twenty-nine (53.7%) eyes exhibited IS/OS junction disruption. Groups 1 and 2 differed significantly with respect to BCVA (p=0.038), but groups 2 and 3 did not (p=0.070). Central macular thickness was significantly greater in group 2 than in group 1 (p=0.031) and in group 3 than in group 2 (p=0.033). Groups 1 and 2 differed significantly in terms of IS/OS disruption (p=0.000), but groups 2 and 3 did not (p=0.310). Conclusions: The IS/OS junction appears to be disrupted during the early stages of ERM. Grade 3 ERM is associated with a significantly higher incidence of IS/OS disruption.
