Evaluation of prenatal vitamin-mineral preparations in the context of recommended dietary supplementation. Are pregnant women supplied with what they should get?

open access: yesRoczniki Panstwowego Zakladu Higieny, 2021
Background. The composition of preparations, intended for pregnant women is an important issue of proper dietary supplementation. The range of such products on the market is very wide and their composition is not regulated by law. Objectives.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

The study found a significant improvement in HB and ferritin levels after one month of treatment in all three maltose, sucrose, and iron dextran groups. Insignificant variances have been found in iron [PDF]

open access: yesAl-Azhar International Medical Journal
Background: Iron Deficiency Anemia (IDA) is the most severe result of iron deficiency and is still regarded as the most frequent dietary deficit globally.Aims and objectives: To assess the safety and efficacy of distinct types of iron preparations in the

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

Genetic dissection of human ABCE1 in yeast reveals separable requirements for ribosome recycling and suppression of aberrant reinitiation

open access: yesFEBS Open Bio, EarlyView.
Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1

open access: yesFEBS Open Bio, EarlyView.
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

open access: yesFEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...
