Bounded variation solutions to Sturm-Liouville problems

open access: yesElectronic Journal of Differential Equations, 2018
In this article we consider singular Sturm-Liouville problems whose right-hand side is a function of bounded Jordan variation. We present necessary and sufficient conditions for all solutions to be of bounded Jordan variation.

Phosphomimetic mutations near active sites of proteins in Thermus thermophilus suggest a widespread regulatory mechanism

open access: yesFEBS Open Bio, EarlyView.
In Thermus thermophilus, more than half of the phosphorylation sites identified by proteomic analysis are located near the active site. All phosphomimetic mutants of phosphosites of six enzymes belonging to different families showed severely reduced activity compared with the wild‐type, particularly in the turnover number.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

Existence of $psi$-bounded solutions for a system of differential equations

open access: yesElectronic Journal of Differential Equations, 2004
In this article, we present a necessary and sufficient condition for the existence of solutions to the linear nonhomogeneous system $x'=A(t)x + f(t)$. Under the condition stated, for every Lebesgue $Psi$-integrable function $f$ there is at least one $Psi$
