(Elsevier, 2020)The aim of this study is to investigate the antioxidant, anticholinesterase and the antiproliferative activities of some chalcones, benzoyl and sulfonyl hydrazones. The antioxidant activity was studied by way of four ... -
Metals/metalloid in Marine Sediments, Bioaccumulating in Macroalgae and a Mussel
(Taylor & Francis Inc, 2020)The aim of the present work is to broaden our knowledge on the variability of metals and metalloid concentration levels in surface sediments, macroalgae and mollusc. Accordingly, As, Co, Cr, Cu, Mn, Mo, Ni, Pb, and Zn ... -
Rarely convergent sequences in topological spaces
(Academic Publication Council, 2020)In this work, by using rare sets, we introduce a new type of convergence in topological spaces, called rare convergence, which is weaker than ordinary convergence. After presenting some examples, we investigate the ... -
The Khorana score for prediction of venous thromboembolism in cancer patients: An individual patient data meta-analysis
(Wiley, 2020)Background Oncology guidelines suggest using the Khorana score to select ambulatory cancer patients receiving chemotherapy for primary venous thromboembolism (VTE) prevention, but its performance in different cancers remains ... -
Transcriptional analyses of the effects ofCatharanthus roseusL. medicinal plant extracts on some markers related to obesity and inflammation in 3T3-L1 mouse cell lines
(Springer, 2020)Catharanthus roseusL. (C. roseus) is one of the medicinal plants used to treat diabetes. In this study, 3T3-L1 preadipocyte cell lines which are fully differentiated into adipocytes were utilized and these were treated ... -
Discrete Ricci curvature-based statistics for soft sets
(Springer, 2020)Soft sets are efficient mathematical structures to model systems in multiple relations. Since a soft set is basically set system, it is possible to endow them with a proper distance function to obtain a metric space. By ... -
Performance of maximum EWMA control chart in the presence of measurement error using auxiliary information
(Taylor & Francis Inc, 2020)EWMA and Max-EWMA charts are considered efficient for individual as well as joint monitoring of mean and variance shifts in the production process. However, measurement error is affecting the efficiency of these charts. ... -
Comparison of partial least squares with other prediction methods via generated data
(Taylor & Francis Ltd, 2020)The purpose of this study is to compare the Partial Least Squares (PLS), Ridge Regression (RR) and Principal Components Regression (PCR) methods, used to fit regressors with severe multicollinearity against a dependent ... -
Salicylidene acylhydrazides attenuate survival of SH-SY5Y neuroblastoma cells through affecting mitotic regulator Speedy/RINGO and ERK/MAPK-PI3K/AKT signaling
(Humana Press Inc, 2020)Salicylidene acylhydrazide group synthetic compounds ME0053, ME005 and ME0192 are known for their iron chelating properties and due to these properties they are primarily used for blocking the bacterial type 3 secretory ... -
Censored Nonparametric Time-Series Analysis with Autoregressive Error Models
(Springer, 2020)This paper focuses on nonparametric regression modeling of time-series observations with data irregularities, such as censoring due to a cutoff value. In general, researchers do not prefer to put up with censored cases in ... -
Cell response to PLA scaffolds functionalized with various seaweed polysaccharides
(Taylor & Francis As, 2020)The porous polylactic acid matrix has been particularly developed as a scaffold in tissue engineering, drug loading, and wound dressing. However, the loading of active chemical compounds is challenging due to its highly ... -

Analogy between periodic patterns in thin smectic liquid crystal films and the intermediate state of superconductors
(Natl Acad Sciences, 2020)Spontaneous breaking of symmetry in liquid crystal (LC) films often reveals itself as a microscopic pattern of molecular align-ment. In a smectic-A LC, the emergence of positional order at the transition from the nematic ... -
