Abstract
Subarachnoid space (SAS) and cystic metastatic lesions of brain parenchyma appear hypointense on fluid-attenuated inversion-recovery (FLAIR) and T1-weighted magnetic resonance imaging (MRI) unless there is a hemorrhage or elevated protein content. Otherwise, delayed enhancement and accumulation of contrast media in SAS or cyst of metastases should be considered. We present hyperintense SAS and cystic brain metastases of lung cancer on FLAIR and T1-weighted MRI, respectively, in a patient who had been previously given contrast media for imaging of spinal metastases and had mildly impaired renal functions, and discuss the relevant literature.

Ramachandran space of Glycine and Proline
The following two plots are made according to the statistical values provided by the Richardson group. I download the KINEMAGE format of Glycine and Proline. Inside the two files, core and allowed regions are defined and can be extracted to make my own Ramachandran plot. The defined core and allowed regions are also shown in http://stats.wordpress.com/b.gif?host=kpwu.wordpress.com&blog=76132&post=397&subd=kpwu&ref=&feed=1

Re: Real space R values
Hi, The map for which you'd like to calculate the Real Space R-values is the 2Fo-Fc map (or the equivalent, based on ML calculation). It's this map to which

Re: Real space R values
Please use CNS v1.3. In this latest version, model_map.inp computes both Fo-Fc and 2Fo-Fc maps and calculates the real space R value from the 2Fo-Fc map. Axel

In-cell protein NMR and protein leakage.
Proteins. 2010 Oct 11;
Authors: Barnes CO, Pielak GJ
In-cell nuclear magnetic resonance spectroscopy is a tool for studying proteins under physiologically relevant conditions. In some instances, however, protein signals from leaked protein are observed in the liquid surrounding the cells. Here, we examine the expression of four proteins in Escherichia coli. We describe the controls that should be used for in-cell NMR experiments and show that leakage is likely when...

Interstellar Space
One of the most ancient 2-D experiments has always been more talked about than practiced. The INADEQUATE was invented 30 years ago (an era in which many chemists were still using CW-NMR) and has always been regarded as a the future thing, like travels to the Moon. Everybody agrees it is useful, but the experimental difficulties are discouraging.
The information that can be extracted by this experiment is a formidable aid to unveil the structure of unknown natural compounds. For a long time, however, the experiment has been nearly impossible. You needed a powerful...
