Tripotent Divisor Graph of a Commutative Ring

open access: yesInternational Journal of Mathematics and Mathematical Sciences
In this work, we introduce a new concept called the tripotent divisor graph of a commutative ring. It is defined with vertices set in a ring R, where distinct vertices r1 and r2 are connected by an edge if their product belongs to the set of all nonunite

CD133 (Prominin) Negative Human Neural Stem Cells Are Clonogenic and Tripotent

open access: yesPLoS ONE, 2009
BackgroundCD133 (Prominin) is widely used as a marker for the identification and isolation of neural precursor cells from normal brain or tumor tissue. However, the assumption that CD133 is expressed constitutively in neural precursor cells has not been ...

Promoting the Differentiation of Neural Progenitor Cells into Oligodendrocytes through the Induction of Olig2 Expression: A Transcriptomic Study Using RNA-seq Analysis [PDF]

open access: yesCells, 2023
Oligodendrocytes are the myelinating cells of the central nervous system that facilitate efficient signal transduction. The loss of these cells and the associated myelin sheath can lead to profound functional deficits.

Co-Tripotent Elements

open access: yesZanco Journal of Pure and Applied Sciences, 2019
In this paper, the concept of a co-tripotent element is introduced. The main purpose is to discuss co-tripotent elements of the ring , where , ( and are two distinct odd primes and ).

Tripotent Lgr5 stem cells in the posterior tongue generate lingual, taste, and salivary gland lineages [PDF]

open access: yesNature Communications
The circumvallate papillae and foliate papillae of the posterior tongue contain taste buds in close proximity to specialized salivary glands, known as von Ebner glands.

The MITF paralog tfec is required in neural crest development for fate specification of the iridophore lineage from a multipotent pigment cell progenitor. [PDF]

open access: yesPLoS ONE, 2021
Understanding how fate specification of distinct cell-types from multipotent progenitors occurs is a fundamental question in embryology. Neural crest stem cells (NCSCs) generate extraordinarily diverse derivatives, including multiple neural, skeletogenic

Characterization of single cell derived cultures of periosteal progenitor cells to ensure the cell quality for clinical application. [PDF]

open access: yesPLoS ONE, 2017
For clinical applications of cells and tissue engineering products it is of importance to characterize the quality of the used cells in detail. Progenitor cells from the periosteum are already routinely applied in the clinics for the regeneration of the ...

Tri-Lineage Differentiation Potential of Stem Cells from Human Exfoliated Deciduous Teeth - An In-vitro Study

open access: yesJournal of Pharmacy and Bioallied Sciences
Background: The use of SHED might bring advantages for tissue engineering over the use of stem cells from adult human teeth as SHEDs were reported to have higher proliferation rate and increase cell population doublings as compared with stem cells from ...

Triality Groups Associated with Triple Systems and their Homotope Algebras

open access: yesAnnales Mathematicae Silesianae, 2021
We introduce the notion of an (α, β, γ) triple system, which generalizes the familiar generalized Jordan triple system related to a construction of simple Lie algebras. We then discuss its realization by considering some bilinear algebras and vice versa.

On the spectrum of linear combinations of finitely many diagonalizable matrices that mutually commute

open access: yesSpecial Matrices, 2021
We propose an algorithm, which is based on the method given by Kişi and Özdemir in [Math Commun, 23 (2018) 61], to handle the problem of when a linear combination matrix X=∑i=1mciXiX = \sum\nolimits_{i = 1}^m {{c_i}{X_i}} is a matrix such that its ...
