In this work, we studied atomic self-diffusion and structural phase transformation in a single iron mononitride (FeN) thin film deposited at an optimized substrate temperature (Ts) of 423 K. At Ts, the FeN exhibits tetrahedral coordination between Fe N atoms (ZnS-type structure with lattice parameter 4.28 Å). The was by combining x-ray diffraction K-edge absorption spectroscopy conversion elect...

Oligonucleosomal fragmentation of chromosomes in dying cells is a hallmark of apoptosis. Little is known about how it is executed or what cellular components are involved. We show that crn-1, a Caenorhabditis elegans homologue of human flap endonuclease-1 (FEN-1) that is normally involved in DNA replication and repair, is also important for apoptosis. Reduction of crn-1 activity by RNA interfer...

Olmesartan Medoxomil (OLM), Ramipril (RPL) & Fenofibric acid (FA) are used to treat hypertension and cardiovascular disease. These drugs undergo hydrolytic metabolism by the enzyme liver esterase and converts into their respective active metabolites Olmesartan (OL), Ramiprilat (RPT) and Fenofibric acid (FA) for OLM, RPL and FEN respectively. In this study the competitive metabolism of OLM, in p...

Gas drilling into the Marcellus Shale play has been linked to environmental issues, including potential impacts on wildlife. In 2009, three separate accidents occurred at two gas well sites in central Pennsylvania, USA that resulted high levels of contaminants Wallace Mine Fen and a headwater stream flows through fen. We collected water chemistry, vegetation, amphibian data impacted fen control...

Over the years, a variety of diets and drugs for the treatment of obesity have come and gone. More recently, newspapers, radio, and television have featured the rise and fall of the latest appetite-suppressants, dexfenfluramine and the combination of fenfluramine and phentermine (fen/phen). The rise occurred after approval of dexfenfluramine by the Food and Drug Administration (FDA); the fall w...

0003-3472 2013 The Association for the Study of A http://dx.doi.org/10.1016/j.anbehav.2013.01.005 With their landmark publication ‘Cuckoos versus reed warblers: adaptations and counteradaptations’ (Animal Behaviour, 1988, 36, 262-284), Davies & Brooke ushered in a new era of research on avian brood parasitism. Building on centuries of rich natural history and detailed observation of common cuck...

To the Editor: The review by Fishman1 seems to bring simple answers to a rather complex problem that deserves a more exhaustive analysis. This article establishes a link between an aminorex epidemic of pulmonary hypertension between 1965 and 1972 and the recent fenfluramine affair. By deductive reasoning, the author suggests that all of the complications attributed to fen-phen or fenfluramine a...
