Internal Direct Products of Groupoids
Journal of Algebra, 1999 A groupoid \((G,\beta)\) is the internal direct product of its non-empty subgroupoids \(G_1\) and \(G_2\) if and only if the mapping \(\theta\colon(x_1,x_2)\to x_1x_2\beta\) (Polish notation!) is an isomorphism from \(G_1\times G_2\) onto \(G\). Projections \(\alpha_1\) and \(\alpha_2\) from \(G\) onto \(G_1\) and \(G_2\), respectively, are defined by \

On Fuzzy Internal Direct Product
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 The main aim of this paper is to introduce the concept of a Fuzzy Internal Direct Product of fuzzy subgroups of group . We study some properties and prove some theorems about this concept ,which is very important and interesting of fuzzy groups and very

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

J Replacement and Direct Roots of Direct Powers in Direct Products
Journal of Algebra, 1995 This article is a continuation of the author's previous works and dedicated to studying the replaceability properties of the direct product of groups. Here is the main definition. Let \(J\) be the infinite cyclic group and let \(\times^n C\) denote the direct product of \(n\) copies of the group \(C\). Consider the statements (1.1) \(J\times C\approx J\

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Permutable subgroups of a direct product
Journal of Algebra, 2003 A subgroup \(S\) of a group \(G\) that permutes with each subgroup of \(G\) is said to be `permutable' (quasinormal). The author continues his investigations on characterizing permutable subgroups of a direct product \(G\times H\) of finite groups which reduces to the case that \(G\times H\) is a \(p\)-group, the focus for this article.
