Spectroscopic Determination of Metal-Ligand Coordination by Biologically Active 2-Picolinehydroxamic Acid With Iron(III) and Oxidovanadium(IV) in Aqueous Solutions

Acta Chimica Slovenica, 2019
The complexing properties of 2-picolinehydroxamic acid towards iron(III) as well as oxidovanadium(IV) were characterized in aqueous solutions by the UV-Vis spectrophotometric method.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

An Idempotent-Based Generalization of Semicommutative Rings

Mathematics
We introduce and study several new classes of rings defined by idempotent conditions. A ring R is called i-semicommutative if (1−ab)aRb(1−ab)=0 whenever ab is a nonzero idempotent. This property lies strictly between semicommutativity and i-reversibility

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

FIXED PROLONGED REGIME OF COMBINED ORAL CONTRACEPTIVES (COC) INTAKE IN SOLUTION OF CLASSIC CONTRACEPTION ISSUES (LITERATURE REVIEW)

Медицинский совет, 2017
Combined oral contraceptives (COC) – the most popular reversible method to prevent unwanted pregnancy used in the whole world. The popularity of COC remains unchanged since the moment of their appearance [1]. Thus, in the US COC are used by each 4 out of
