Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

open access: yesFEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

Theoretical Analysis of Poly(difluoroacetylene) [PDF]

open access: yesThe Journal of Physical Chemistry B, 2003
The electronic structure of poly(difluoroacetylene) was investigated with the aim of determining whether it is a good candidate for a conducting polymer with high n-type conductivity. Positions of valence and conduction bands and bandwidths indicate that planar all-trans poly(difluoroacetylene) is p- and n-dopable and that on-chain mobility of ...

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Correspondence analysis for strong three-valued logic [PDF]

open access: yes, 2014
I apply Kooi and Tamminga's (2012) idea of correspondence analysis for many-valued logics to strong three-valued logic (K3). First, I characterize each possible single entry in the truth-table of a unary or a binary truth-functional operator that could ...

Theoretical Analysis of Microtubule Dynamics at All Times

open access: yes, 2014
Microtubules are biopolymers consisting of tubulin dimer subunits. As a major component of cytoskeleton they are essential for supporting most important cellular processes such as cell division, signaling, intracellular transport and cell locomotion. The

A computational and theoretical investigation of the accuracy of quasicontinuum methods [PDF]

open access: yes, 2011
We give computational results to study the accuracy of several quasicontinuum methods for two benchmark problems – the stability of a Lomer dislocation pair under shear and the stability of a lattice to plastic slip under tensile loading.

Set Theoretic Real Analysis

open access: yesJournal of Applied Analysis, 1997
The article has a survey character. It deals with some results and problems concerning functions \(f: \mathbb{R}^n\to\mathbb{R}\) whose solutions or statements involve the use of set theory. The choice of the topics can be characterized by key words and phrases: Fubini theorem, continuous images, continuous restrictions, continuum hypothesis, Martin's ...

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐
