The multifaceted nature of this disease and its intrinsic complexity make this disease very difficult to analyze experimentally as a whole. The use of quantitative methods, in the form of mathematical
models and computational tools, to examine the disease has been a very powerful tool in providing predictions and insights about the underlying mechanism(s) regulating its onset and development. Furthermore, the models developed may have prognostic implications by aiding in the enrollment of HRS into trials for T1D prevention. In this review, we summarize recent advances made in determining T- and B-cell involvement in T1D using these quantitative approaches and delineate areas where mathematical modeling can make further contributions in unraveling certain aspect of this disease.”
“Multiblock copolymers consisting of poly(l-lactic PFTα acid) and poly(dimethyl siloxane) were prepared by the polycondensation of oligo(l-lactic acid) (OLLA) with dihydroxyl-terminated oligo(dimethyl siloxane) and dicarboxyl-terminated Selisistat nmr oligo(dimethyl siloxane). Copolymers with number-average molecular weights of 18,000-33,000 Da and various content ratios of oligo(dimethyl siloxane) (ODMS) unit were obtained by changing the feed ratio of these oligomers. A film prepared from the copolymer with an ODMS content ratio
of 0.37 exhibited two independent peaks at -107 degrees C and 37 degrees C in the mechanical loss tangent for temperature dependence, suggesting the formation of microphase separation between the OLLA and ODMS segments. The film had a tensile strength of 3.2 MPa and a high elongation of 132%. The film also exhibited a high strain recovery even after repeated straining. The incorporation of dimethyl siloxane units as multiblock segments was confirmed to improve the flexibility of poly(l-lactic acid). (c) 2013 Wiley Periodicals, Inc. J. Appl. Polym.

“Fibrillins and LTBPs [latent
TGF beta (transforming growth factor beta)-binding proteins] perform vital and complex roles in the extracellular matrix and are relevant to a wide range of human diseases. These proteins share a signature ‘eight cysteine’ or ‘TB (TGF beta-binding protein-like)’ domain that is found nowhere else in the human proteome, and which has been shown to mediate a variety of protein MEK inhibitor protein interactions. These include covalent binding of the TGF beta propeptide, and RGD-directed interactions with a repertoire of integrins. TB domains are found interspersed with long arrays of EGF (epidermal growth factor)-like domains, which occur more widely in extracellular proteins, and also mediate binding to a large number of proteins and proteoglycans. In the present paper, newly available protein sequence information from a variety of sources is reviewed and related to published findings on the structure and function of fibrillins and LTBPs.
