INTRODUCTION: Chorioallantoic fusion is essential for development of the labyrinth layer of the mouse placenta. However, events that occur after chorioallantoic attachment remain poorly described, partly due to difficulties of conducting ex vivo analysis of the placenta. Herein, we report conditions for ex vivo culture of the developing murine placenta. METHODS: Mesometrial halves of decidua containing pre-attachment chorions were cultured alone or with explants of allantoides from stage-matched controls and analyzed by confocal and immunofluorescence microscopy...

BACKGROUND: Matrix metalloproteinase (MMP) inhibitors decrease inflammation in normal tissues and suppress cancer progress in normal tissues. Valproic acid (VA) and doxycycline (DX) are MMP inhibitors that have radio-protective effects. Their ability to inhibit MMPs in irradiated tissue is unknown and the role of MMPs in radio-protective effects has not been tested to date. AIMS: The purpose of this study was to examine whether administration of VA and DX to rats before irradiation affects tissue inflammation and apoptosis in the early phase of radiation, and whether the effect of these drugs is mediated by MMP inhibition...

Supportless Pt catalysts have several advantages over conventional carbon-supported Pt catalysts in that they are not susceptible to carbon corrosion. However, the need for high Pt loadings in membrane electrode assemblies (MEAs) to achieve state-of-the-art fuel cell performance has limited their application in proton exchange membrane fuel cells. Herein, we report a new approach to the design of a supportless Pt catalyst in terms of catalyst layer architecture, which is crucial for fuel cell performance as it affects water management and oxygen transport in the catalyst layers...
