We demonstrate the difference between local, single-particle dynamics and global dynamics of entangled quantum systems coupled to independent environments. Using an all-optical experimental setup, we showed that, even when the environment-induced decay of each system is asymptotic, quantum entanglement may suddenly disappear. This "sudden death" constitutes yet another distinct and counterintuitive trait of entanglement.
A study was carried out in Glasgow of the cause of death in patients with rheumatoid arthritis.
Research about Maori children's experiences and perceptions of death and tangi (Maori death rituals) is sparse. What is available tends to be generalised and stems from Western paradigms of knowledge. In this study we explore Maori children's experiences of death and tangi through the eyes of Maori parents. Through semi-structured interviews with 17 Maori parents, five areas were explored: a) the childhood experiences of parents and how they learned about death and an afterlife; b) what their adult beliefs about these matters are; c) how they have communicated the death concept to their children; and d) whether their children are likely to do the same in the future. From this study we learn that death was not hidden from children, that parents talked with their children in very open and age relevant ways, and considered their children'...

Crib death remains poorly understood both morphologically and functionally. The cardiac hypotheses postulating that crib death is due to lethal cardiac electrical instability is gathering a renewed interest. Aim of this work is to examine the likely role of Mahaim fibers in relation to crib death. We analyze 72 autopsied cases of crib death (47 male and 26 female infants, ranging in age from 3 to 365 days) and 24 age-matched controls. Mahaim fibers were found in 21% of crib death and in 8% of control cases. Mahaim fibers are specialized accessory pathways connecting the atrio-ventricular junction and the upper ventricular septum. These fibers, under particular conditions and/or neurovegetative stimuli, may cause pre-excitation and potentially malignant arrhythmias. The whole atrio-ventricular system or its junctional tract, can become...

In order to provide a more extensive investigation of what this issue tells us about the Constitution in American life, the Center for Policy Studies has invited three members of our faculty for a panel discussion, based on their varied experience as a death penalty litigator, constitutional lawyer, and ethicist, and to respond to a series of questions from a student panel.
FCH/CIP4 homology-Bin-Amphiphysin-Rvs (F-BAR) domain proteins are a subfamily of the Bin-Amphiphysin-Rvs (BAR) superfamily of proteins. They contain unique domains that bind and reshape the phospholipid bilayers of endosomal compartments during endocytosis. Using a functional assay for cell survival, we identified an F-BAR protein, FCH/CIP4 homology and double Src homology 3 domains 2 (FCHSD2), that confers drug resistance. Stable expression of shRNA against FCHSD2 in multiple cell types showed that loss of FCHSD2 sensitized cells to apoptosis by doxorubicin. Silencing of FCHSD2 also enhanced the ability of fibroblasts to grow colonies in culture. Mass spectrometry analysis of FCHSD2 protein complexes identified multiple interacting proteins that are involved in adhesion and endosome trafficking. We identified and confirmed a novel int...
Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system resulting from a viral infection. JC virus (John Cunningham) is known to cause the demyelinating lesions in the white matter, but how oligodendrocyte death is really initiated during disease course is still under question. Besides the demyelination pathology, inflammation can be detected in the brain parenchyma of PML-patients. Though it is not established how the immune response including both activation of CD8+ cytotoxic T-lymphocytes and granzyme B release is involved in the pathogenesis. Therefore histochemical and immunohistochemical experiments were performed in order to get a better insight. The results of the investigations showed that the immune response is playing a minor role in PML and that hence induction of oligodendr...
