Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

open access: yesFEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Existence of infinitely many periodic subharmonic solutions for nonlinear non-autonomous neutral differential equations

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we study the existence of an infinite number of subharmonic periodic solutions to a class of second-order neutral nonlinear functional differential equations.

A working model for cytoplasmic assembly of H/ACA snoRNPs

open access: yesFEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Existence of solutions to fractional Hamiltonian systems with combined nonlinearities

open access: yesElectronic Journal of Differential Equations, 2016
This article concerns the existence of solutions for the fractional Hamiltonian system $$\displaylines{ - _tD^{\alpha}_{\infty}\big(_{-\infty}D^{\alpha}_{t}u(t)\big) -L(t)u(t)+\nabla W(t,u(t))=0,\cr u\in H^{\alpha}(\mathbb{R},\mathbb{R}^n ...

Cell‐free DNA aneuploidy score as a dynamic early response marker in prostate cancer

open access: yesMolecular Oncology, EarlyView.
mFast‐SeqS‐based genome‐wide aneuploidy scores are concordant with aneuploidy scores obtained by whole genome sequencing from tumor tissue and can predict response to ARSI treatment at baseline and, at an early time point, to ARSI and taxanes. This assay can be easily performed at low cost and requires little input of cfDNA. Cell‐free circulating tumor
