TL;DR: The general principles formulated in this paper may be summarized as follows: What is experienced and reported as pain is a psychological phenomenon and disordered neural patterns originating in the periphery confer certain qualities on the pain experience that permit the physician to recognize their presence and hence make a presumptive diagnosis of an organic lesion.

TL;DR: A simple and effective mechanism by which PCa cells can synthesize a constitutively active AR and thus circumvent androgen ablation is described.
Abstract: The standard systemic treatment for prostate cancer (PCa) is androgen ablation, which causes tumor regression by inhibiting activity of the androgen receptor (AR). Invariably, PCa recurs with a fatal androgen-refractory phenotype. Importantly, the growth of androgen-refractory PCa remains dependent on the AR through various mechanisms of aberrant AR activation. Here, we studied the 22Rv1 PCa cell line, which was derived from a CWR22 xenograft that relapsed during androgen ablation. Three AR isoforms are expressed in 22Rv1 cells: a full-length version with duplicated exon 3 and two truncated versions lacking the COOH terminal domain (CTD). We found that CTD-truncated AR isoforms are encoded by mRNAs that have a novel exon 2b at their 3' end. Functionally, these AR isoforms are constitutively active and promote the expression of endogenous AR-dependent genes, as well as the proliferation of 22Rv1 cells in a ligand-independent manner. AR mRNAs containing exon 2b and their protein products are expressed in commonly studied PCa cell lines. Moreover, exon 2b-derived species are enriched in xenograft-based models of therapy-resistant PCa. Together, our data describe a simple and effective mechanism by which PCa cells can synthesize a constitutively active AR and thus circumvent androgen ablation.

TL;DR: In this paper, the Hodrick-Prescott (1980) filter was applied to U.S. time series and to simulated outcomes of real business cycle models and the results showed that the HP filter dramatically altered measures of persistence, variability, and comovement.

TL;DR: This work reports increased dendritic spine density with reduced developmental spine pruning in layer V pyramidal neurons in postmortem ASD temporal lobe and suggests that mTOR-regulated autophagy is required for developmental spinePruning, and activation of neuronal Autophagy corrects synaptic pathology and social behavior deficits in ASD models with hyperactivated mTOR.

TL;DR: It is suggested that the extensibility of the modular fibronectin type III region may be important in allowing tenascin–ligand bonds to persist over long extensions, and of widespread use in extracellular proteins containing such domain.
Abstract: Extracellular matrix proteins are thought to provide a rigid mechanical anchor that supports and guides migrating and rolling cells. Here we examine the mechanical properties of the extracellular matrix protein tenascin by using atomic-force-microscopy techniques. Our results indicate that tenascin is an elastic protein. Single molecules of tenascin could be stretched to several times their resting length. Force-extension curves showed a saw-tooth pattern, with peaks of force at 137pN. These peaks were approximately 25 nm apart. Similar results have been obtained by study of titin. We also found similar results by studying recombinant tenascin fragments encompassing the 15 fibronectin type III domains of tenascin. This indicates that the extensibility of tenascin may be due to the stretch-induced unfolding of its fibronectin type III domains. Refolding of tenascin after stretching, observed when the force was reduced to near zero, showed a double-exponential recovery with time constants of 42 domains refolded per second and 0.5 domains per second. The former speed of refolding is more than twice as fast as any previously reported speed of refolding of a fibronectin type III domain. We suggest that the extensibility of the modular fibronectin type III region may be important in allowing tenascin-ligand bonds to persist over long extensions. These properties of fibronectin type III modules may be of widespread use in extracellular proteins containing such domain.
