Nausea and vomiting during pregnancy: a possible correlation with obsessive compulsive disorder and alexithymia
(Taylor & Francis Inc, 2022)
The possible correlation between nausea and vomiting during pregnancy (NVP) with obsessive-compulsive disorder (OCD) and alexithymia were examined in this cross-sectional study. A cohort of pregnant women at the first ...
New Schiffbases with a 2,6-bis(2-aminophenylthio)pyridine moiety acting as glutathione reductase activator and inhibitors: Synthesis and molecular docking studies
(Elsevier, 2022)
2,6-bis(2-aminophenylthio)pyridine was synthesized and identified by x-ray diffraction method. Its new Schiffbases (H2L1, H2L2, L-3 and L-4) were synthesized and characterized by elemental analysis, FT-IR, LC-MS, H-1 NMR ...
Stability of spatial patterns in a diffusive oxygen-plankton model with time lag effect
(Elsevier, 2022)
Although marine ecosystem is a highly complex phenomenon with many non-linearly interacting species, dissolved oxygen and plankton among these have perhaps the most fundamental relationship not only for the protection of ...

On r-circulant matrices with generalized bi-periodic Fibonacci numbers
(Springer Heidelberg, 2022)
In this paper, we calculate the Frobenius norm, and give upper and lower bounds for the spectral norm of r-circulant matrices whose entries are defined in terms of generalized bi-periodic Fibonacci numbers. We also provide ...
LC/MS-MS Analyses and in vitro anticancer activity of Tourneuxia variifolia extracts
(Taylor & Francis Ltd, 2022)
Several Saharan plants, despite their abundance of natural compounds, have received little attention. In this study, the chemical composition of polar extracts of Tourneuxia variifolia Coss. (Asteraceae), an endemic species ...
A composite ranking of risk factors for COVID-19 time-to-event data from a Turkish cohort
(Elsevier Sci Ltd, 2022)
Having a complete and reliable list of risk factors from routine laboratory blood test for COVID-19 disease severity and mortality is important for patient care and hospital management. It is common to use meta-analysis ...
New metallophthalocyanines including benzylphenoxy groups and investigation of their organic-field effect transistor (OFET) features
(Elsevier Sci Ltd, 2022)
In this study, metal and metal-free novel phthalocyanines containing peripheral and non-peripheral tetra 2-ben-zylphenoxy groups were synthesized. The compounds were characterized by UV-Vis, FT-IR, H-1 NMR, and MALDI-TOF ...
