“Alzheimer’s disease is diagnosed by postmortem detection of pathological lesions that accumulate in specific brain regions. Although the presence of both beta-amyloid plaques and tau-bearing neurofibrillary lesions defines Alzheimer’s disease, the distribution of neurofibrillary lesions alone correlates strongly with neurodegeneration Selleckchem BB-94 and cognitive decline. A whole-brain imaging test capable of detecting these lesions in premortem cases could have great potential for staging and differentially diagnosing Alzheimer’s disease. Here we discuss the challenges in developing a whole-brain imaging approach for detection

of this intracellular target.”
“Despite being discovered in animals in the early 20th century, the scientific interest in retroviruses was boosted with the discovery of human retroviruses (human T-leukemia/lymphoma virus (HTLV) and HIV), which are responsible for significant morbidity and mortality. HTLV was identified more than 25 years ago as the etiological agent of adult T-cell leukemia/lymphoma. It was then shown to be a complex retrovirus, given that it not only encodes the characteristic retroviral Gag, Pol and Env proteins, but also regulatory and accessory proteins. Since the first studies documenting the role of these proteins in viral expression, the picture has become increasingly more complex. Indeed, owing to the limited size of its BEZ235 genome that contains overlapping open-reading frames, HTLV has evolved unique ways to regulate its expression. Retroviral expression was originally thought to be mainly controlled through the regulation of transcription from the 5′ long-terminal repeats, but we now know that the 3′ long-terminal repeats also selleck compound serve as promoters. Regulation of splicing and mRNA export,

and post-translational modifications of viral protein also play a major role. This review discusses the latest insights gained into the field of HTLV gene expression.”
“To describe the critical current density (J(c)) as the function of applied magnetic field (B-a) in high quality YBa2Cu3O7 (YBCO) superconducting films, the vortex pinning mechanism along the structural domain boundaries of the films is developed. The boundaries, assumed to have low misorientation angles, are quantitatively considered to consist of individual edge dislocations acting as pinning wells, rather than a continuous boundary. This extended model accurately describes the experimental J(c)(B-a) over the wide field and temperature ranges. Marginal deviations of the model from the experimental J(c)(B-a) curves are observed at high fields and temperatures where thermally activated depinning is significant. This pinning model is verified to provide precise structural properties of the films which can be obtained by other considerations. (C) 2010 American Institute of Physics.
