Postnatal Involution and Counter-Involution of the Thymus [PDF]

open access: yesFrontiers in Immunology, 2020
Thymus involution occurs in all vertebrates. It is thought to impact on immune responses in the aged, and in other clinical circumstances such as bone marrow transplantation. Determinants of thymus growth and size are beginning to be identified.

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.

Study on the Pattern of Postpartum Uterine Involution in Dairy Cows

open access: yesAnimals, 2023
Postpartum uterine involution is necessary for the normal reproduction of dairy cows. The study aimed to investigate the pattern of postpartum uterine involution and the impact of parity on uterine involution in Chinese Holstein dairy cows.

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.

A Statistic on Involutions [PDF]

open access: yesJournal of Algebraic Combinatorics, 2001
Given positive integers \(i< j\), the authors define an arc \([i, j]\) with span \(j-i-1\). An involution is a finite set of disjoint arcs. If \(i< k< j< l\), then \([i, j]\), \([k, l]\) are crossing arcs. \(I(n)\) denote the set of all involutions with arcs contained in \([n]\) (\(=\{1,2,\dots,n\}\)) and \(I(n, k)\) the set of involutions in \(I(n ...

Quaternion involutions and anti-involutions

open access: yesComputers & Mathematics with Applications, 2007
The authors recall the definition of Hamilton's algebra of real quaternions. They define an involution of an algebra, without mentioning the structure where the involution takes place, and remark that the formal definition of an involution is not easy to find. Then an anti-involution is defined. Some calculations are added.

Human Thymic Involution and Aging in Humanized Mice

open access: yesFrontiers in Immunology, 2020
Thymic involution is an important factor leading to the aging of the immune system. Most of what we know regarding thymic aging comes from mouse models, and the nature of the thymic aging process in humans remains largely unexplored due to the lack of a ...
