The role of Co dopant was identified electronically using x-ray magnetic spectroscopy, revealing that the transition modified the Ni host’s electronic structure and enhanced its moment by effectively spin-polarizing the Ni 3d conduction band. This was distinctly different than in the heat treatment case, which underwent an electronically independent phase

transition. The element-specific magnetic hysteresis of Co and Ni was also probed, which showed that the two elements were magnetically coupled. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3647753]“
“Two different nano-emulsions based on methyl methacrylate/butyl GDC-973 acrylate copolymers have been synthesized to be used as retanning and lubricating agents for chrome-tanned leather. The main difference and characteristics of the two prepared copolymers were studied. The nano particle size of the two copolymers was confirmed using transmission

electron microscope (TEM). The influence of the prepared copolymers on chrome-tanned leather as retanning agents was investigated. The properties of the retanned leather, namely, physicomechanical properties as tensile strength, elongation at break and water absorption, were measured. Thermal gravimetric analysis (TGA) technique was used to examine 5-Fluoracil manufacturer the thermal stability of the retanned leather. Also, the texture of the grain surface and fibers were inspected using scanning electron microscope (SEM). The retanned leather showed an improvement in its physicomechanical properties, as well as enhancement of its thermal stability as compared with the chrome-tanned leather. Furthermore, the retanned leather has uniform dyestuff, softness, and firmness of grain. All these promising

results provide evidence CA3 chemical structure to the applicability of the prepared copolymer emulsions as efficient retanning and lubricating agents for chrome-tanned leather. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012″
“Carcinoid tumors are part of a heterogeneous group of gastrointestinal and pancreatic endocrine tumors that are characterized by their capacity to produce and secrete hormones, 5-hydroxytryptamine, tachykinins and other mediators. These substances are thought to be responsible for the collection of symptoms, which include diarrhea, flushing and wheezing, that is known as carcinoid syndrome. Fibrosis that occurs either local to or distant from the primary tumor is one of the hallmarks of carcinoid tumors that originate from the midgut. The fibrotic process can occur in the mesentery as a desmoplastic response and may lead to obstruction of the small bowel, but it can also occur in the lungs, skin or retroperitoneum. importantly, up to one-third of patients develop cardiac valvulopathy. One or more products that are secreted by the tumor and enter into the circulation are likely to have a role in this process.
