Heterogeneity of cell population is a key component behind the evolutionary success of Escherichia coli. The heterogeneity supports species adaptation and mainly results from lateral gene transfer. Adaptation may also involve genomic alterations that affect regulation of conserved genes. Here we analyzed regulation of the mat (or ecp) genes that ...

Introduction. Pelizaeus-Merzbacher disease (PMD) is caused in most cases by either duplications or point mutations in the PLP1 gene. This disease, a dysmyelinating disorder affecting mainly the central nervous system, has a wide clinical spectrum and its causing mutations act through different molecular mechanisms. Methods. Eighty-eight male patients with leukodystrophy ...

A photo-switchable fluorescent flagging approach has been developed to identify photoaffinity-labeled peptides in target protein. Upon photochemical release of the ligand, the protein was newly modified with a coumarin in place of the previously attached biotin. It allowed us to simplify complex identification processes for labeled sites.

The brain regulates energy homeostasis in the organism. Under resource shortage, the brain takes priority over peripheral organs for energy supply. But can the brain also down-regulate its own consumption to favor survival? We show that the brain of Drosophila specifically disables the costly formation of aversive long-term memory (LTM) ...

BACKGROUND: During storage, red blood cells (RBCs) lose their membrane stability, leading to haemolysis and microparticle (MP) formation. The use of RBCs stored for more than 28 days has been associated with an increased incidence of deep vein thrombosis. However, the exact mechanism by which coagulation activation is enhanced in stored ...

BACKGROUND: Movement changes in pain. Unlike the somewhat stereotypical response of limb muscles to pain, trunk muscle responses are highly variable when challenged by pain in that region. This has led many to question the existence of a common underlying theory to explain the adaptation. Here, we tested the hypotheses ...

In a temperate climate, understory trees leaf out earlier than canopy trees, but the cause of this discrepancy remains unclear. This study aims to investigate whether this discrepancy results from ontogenic changes or from microclimatic differences. Seedlings of five deciduous tree species were grown in spring 2012 in the understory ...

Most organic radicals possess short lifetimes and quickly undergo dimerization or oxidation. Here, we report on the synthesis by radical templation of a class of air- and water-stable organic radicals, trapped within a homo[2]catenane composed of two rigid and fixed cyclobis(paraquat-p-phenylene) rings. The highly energetic octacationic homo[2]catenane, which is capable ...
