A Novel Study on Ordered Anti-Involution LA-Semihypergroups

open access: yesJournal of Mathematics, 2023
In this study, we introduce a new concept called “anti-involution” in relation to ordered LA-semihypergroups. An anti-involution is basically an involuntary automorphism, which is just a fancy term for a mathematical function that can be reversed.

Contributions of Age-Related Thymic Involution to Immunosenescence and Inflammaging

open access: yesImmunity & Ageing, 2020
Immune system aging is characterized by the paradox of immunosenescence (insufficiency) and inflammaging (over-reaction), which incorporate two sides of the same coin, resulting in immune disorder.

On the Existence of $f$-local Subgroups in a Group with Finite Involution

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2022
An $f$-local subgroup of an infinite group is each its infinite subgroup with a nontrivial locally finite radical. An involution is said to be finite in a group if it generates a finite subgroup with each conjugate involution.

Involutions and their progenies [PDF]

open access: yesJournal of Combinatorics, 2015
Any permutation has a disjoint cycle decomposition and concept generates an equivalence class on the symmetry group called the cycle-type. The main focus of this work is on permutations of restricted cycle-types, with particular emphasis on the special class of involutions and their partial sums.

Implications of Oxidative Stress and Cellular Senescence in Age-Related Thymus Involution

open access: yesOxidative Medicine and Cellular Longevity, 2020
The human thymus is a primary lymphoepithelial organ which supports the production of self-tolerant T cells with competent and regulatory functions. Paradoxically, despite the crucial role that it exerts in T cell-mediated immunity and prevention of ...

Consumption of Pineapple Juice to Accelerate Uterine Involution in Postpartum

open access: yesMedia Keperawatan Indonesia, 2023
Post delivery occurs the pelvic wall was always stretched/damaged in the birth canal, and the pelvic floor muscles are loose, hence the implementation of accelerated uterine involution with the consumption of pineapple juice.
