On k-Gamma and k-Beta Distributions and Moment Generating Functions

open access: yesJournal of Probability and Statistics, 2014
The main objective of the present paper is to define k-gamma and k-beta distributions and moments generating function for the said distributions in terms of a new parameter k>0. Also, the authors prove some properties of these newly defined distributions.

Majorization problems for two subclasses of analytic functions connected with the Liu–Owa integral operator and exponential function

open access: yesJournal of Inequalities and Applications, 2018
In the present paper, we investigate majorization properties for the class Mβα(p,γ) $M_{\beta}^{\alpha}(p,\gamma)$ of uniformly starlike functions and the class Nβα(p,θ) $N_{\beta}^{\alpha}(p,\theta)$ of spiral-like functions related to an exponential ...

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Down-modulation of lymphoproliferation and interferon-gamma production by beta-glucan derived from Saccharomyces cerevisiae [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 2003
beta-glucan, one of the major cell wall components of Saccharomyces cerevisiae, has been found to enhance immune functions. This study investigated in vivo and in vitro effects of beta-glucan on lymphoproliferation and interferon-gamma (IFN-gamma ...

On \(\beta-\gamma\)-connectedness and \( \beta_{(\gamma,\delta)}\)-continuous functions

open access: yesMalaya Journal of Matematik
The aim of the paper is to introduce the notion of \(\beta-\gamma\)-separated sets and study their properties in topological spaces,then we introduce the notation of \(\beta-\gamma\)-connected and \(\beta-\gamma\)-disconnectedness. Also, \(\beta-\gamma\)-disconnected spaces are defined through \(\beta-\gamma\)-separated sets and their topological ...

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

A Study on Novel Extensions for the p-adic Gamma and p-adic Beta Functions

open access: yesMathematical and Computational Applications, 2019
In this paper, we introduce the ρ , q -analog of the p-adic factorial function. By utilizing some properties of ρ , q -numbers, we obtain several new and interesting identities and formulas. We then construct the p-adic ρ

Anticancer sensitivities and biological characteristics of HCT116 cells resistant to the selective poly(ADP‐ribose) glycohydrolase inhibitor

open access: yesFEBS Open Bio, EarlyView.
We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a
