Non-merohedral Twinning in Small Molecule and Protein Crystallography
In contrast to twinning by merohedry the reciprocal lattices of the different domains of non-merohedral twins do not overlap exactly. If both twin domains are similar in size, there are often problems with the cell determinations and usual automatic indexing programs fail. But nowadays there are several programs that can deal with such kinds of problems [1], [2], [3]. In principle two different...

متن کاملFocusing optics for molybdenum radiation: a bright laboratory source for small-molecule crystallography
This paper reports the design, installation and testing of a set of multilayer confocal mirrors in a side-by-side arrangement, built to increase the intensity from a molybdenum rotating-anode X-ray source. Ray-tracing experiments were performed in order to evaluate the best design parameters for the system, which are shown to be a side-by-side configuration of 100 mm length. Measurements of the...

In last three decades the attacks against the personal information, social information and financial information become more frequent and sophisticated. Initially, the purpose of cyber attack was the entertainment but as scenario has changed, internet is now seen as wonderful tool to conduct fraud or to grasp the information about anyone else. The paper shows how internet is important for cyber...
متن کاملSmall Molecule-BIO Accelerates and Enhances Marrow-Derived Mesenchymal Stem Cell in Vitro Chondrogenesis
Background: Hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. On the other hand, mesenchymal stem cells (MSCs) are regarded as potent cells with a property of cartilage regeneration. We aimed to optimize marrow-derived MSC chondrogenic culture using a small bioactive molecule referred to as BIO. Methods: MSCs from the ma...
