Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Climate Action Impacts on Steelmaking Emissions of Persistent Organic Pollutants Highlight a Gap Between the Paris Agreement and the Stockholm Convention

Advanced Science, EarlyView.
Emissions of unintentionally produced persistent organic pollutants (UPOPs) and global warming are two major environmental challenges. But their governance has largely evolved in parallel, leaving the toxicity implications of climate‐driven industrial transitions poorly understood.

An Application of Multiple Erdélyi–Kober Fractional Integral Operators to Establish New Inequalities Involving a General Class of Functions

Fractal and Fractional
This research aims to develop generalized fractional integral inequalities by utilizing multiple Erdélyi–Kober (E–K) fractional integral operators. Using a set of j, with (j∈N) positively continuous and decaying functions in the finite interval a≤t≤x ...

Holder's and Hardy's Two Dimensional Diamond-alpha Inequalities on Time Scales [PDF]

, 2009
We prove a two dimensional Holder and reverse-Holder inequality on time scales via the diamond-alpha integral. Other integral inequalities are established as well, which have as corollaries some recent proved Hardy-type inequalities on time scales ...

Filling area conjecture and ovalless real hyperelliptic surfaces

, 2004
We prove the filling area conjecture in the hyperelliptic case. In particular, we establish the conjecture for all genus 1 fillings of the circle, extending P. Pu's result in genus 0.

A general Ostrowski type inequality for double integrals

Tamkang Journal of Mathematics, 2002
Some generalisations of an Ostrowski Type Inequality in two dimensions for $n-$time differentiable mappings are given. The result is an Integral Inequality with bounded $n-$time derivatives. This is employed to approximate double integrals using one dimensional integrals and function evaluations at the boundary and interior points.

Inequalities Including Fractional Integral Operators of General Riemann–Liouville for an Abstract Convex Function and Their Applications

Axioms
An abstract convexity type is B−1–convexity. For B−1–convex functions, the Hermite–Hadamard inequality was previously found. Recently, however, new and more popular types of fractional integral operators have been developed.
