The liquid stream produced during the dewatering of digested sludge in wastewater treatment plants contains significant concentrations of anthropogenic microparticles. Generally, this stream is recirculated into the wastewater line, reintroducing these microparticles into the treatment system. This study focuses on separating these microparticles using ceramic membranes of microfiltration and ultrafiltration. An in-depth resea...

Reperfusion following myocardial infarction salvages the ischemic heart but paradoxically exacerbates injury. Yet, efficient treatment for cardiac ischemia/reperfusion injury is still missing in clinics. ATP release through Pannexin1 (PANX1) channels facilitates recruitment of leukocytes to the injured myocardium. Thus, PANX1 channel inhibition might confer cardioprotection. Currently available PANX1 channel blockers lack spec...

Summary Knowledge on the regulatory mechanisms controlling iron homeostasis in cyanobacteria is limited. In A nabaena sp. PCC 7120, the ferric uptake regulator FurA is a constitutive and essential protein whose expression is induced under iron deprivation. Our previous analyses have shown that this protein acts as a global transcriptional regulator, controlling the expression of several genes belonging to different functional...

Summary Microcystins are toxins produced by cyanobacteria that entail serious health and environmental problems. They are cyclic heptapeptides synthesized via a mixed polyketide synthase/non‐ribosomal peptide synthetase system called microcystin synthetase. Environmental and nutritional factors that trigger microcystin synthesis are still debated and this work deals with the study of the influence of iron nutritional status on...
