Electrochemical microelectrodes are commonly used to record amperometric spikes of current that result from oxidation of transmitter released from individual vesicles during exocytosis. Whereas the exquisite sensitivity of these measurements is well appreciated, a better understanding of the noise sources that limit the resolution of the technique is needed to ...

Microcystins (MCs) are highly liver-specific and evidenced as a liver tumor promoter. Oxidative stress is one of the most important toxicity mechanisms of MCs, which is tightly related to oxygen concentration. The effects of MCs on animals and cell lines in normoxia and the mechanisms have been well studied, but ...

Vertical growth of ZnO nanowires is usually achieved on lattice-matched substrates such as ZnO or sapphire using various vapor transport techniques. Accomplishing this on silicon substrates requires thick ZnO buffer layers. Here we demonstrate growth of vertical ZnO nanowires on FeCrAl substrates. The pre-annealing prior to growth appears to preferentially ...

The patent claims peptidic/nonpeptidic inhibitors of the ghrelin receptor, the growth hormone secretagogue receptor (GHSR) 1A. Among these compounds, it was disclosed that the addition in some compounds of a GlyMetAla tripeptide at the N-terminus of the ghrelin peptide agonists converts them into ghrelin receptor antagonists. One of these peptides, ...

Immunoglobulin A (IgA) is essential to maintain the symbiotic balance between gut bacterial communities and the host immune system. Here we provide evidence that the inhibitory co-receptor programmed cell death-1 (PD-1) regulates the gut microbiota through appropriate selection of IgA plasma cell repertoires. PD-1 deficiency generates an excess number of ...

The patient's perspective evaluated by patient-reported outcomes (PROs) gains more and more importance, since treatment efficacy is no longer solely linked to clinical outcomes like cure and overall survival. Ailments like pain, fatigue and social isolation can only be assessed by patients' direct expression without any interpretation made by medical ...

Abstract Molecular hydrogen (dihydrogen, H(2)) acts as a therapeutic antioxidant by selectively reducing hydroxyl radicals (•OH) and peroxynitrite (ONOO-). It has been well-known that ionizing radiation (IR) causes oxidative damage and consequent apoptosis mainly due to the production of •OH that follows radiolysis of H(2)O. Our department reported the protective ...

BRCA1 germline mutation carriers usually develop ER, PR and HER2 negative breast carcinoma. Somatic BRCA1 mutations are rare in sporadic breast cancers, but other mechanisms could impair BRCA1 functions in these tumors, particularly in triple-negative breast carcinomas (TNBCs). Id4, a helix-loop-helix DNA binding factor, blocks BRCA1 gene transcription in vitro ...
