Structural basis for escaping negative selection by T cell receptor with high affinity for self antigen
… the structure of a human autoimmune TCR (MS2-3C8) bound to a self-peptide from myelin basic protein (MBP) and the multiple sclerosis-associated MHC molecule HLA-DR4. MS2-3C8 is encephalitogenic in humanized transgenic mice. The structure showed loose accommodation of MBP in the HLA-DR4 …

Evaluation of an enhanced magneto-chemical process for the removal of pathogens in wastewater
… of the CoMag(TM) process for the removal of MS2, poliovirus type 1, rotavirus strain Wa, and adenovirus type 2 from secondary effluent wastewater, at 24°C and 4°C. Additionally, the removal of MS2 was assessed using a 100 gpm CoMag(TM) pilot plant. The results indicate that there was …

"The pres/urrection of Deena Larsen's ""Marble Springs, Second Edition"""
… poetic work Marble Springs, Second Edition (MS2). As MS2 is based on Apple’s HyperCard, a software program that is no longer updated or supported, MS2, and other works created in the same environment, face extinction unless action is taken. The experiment below details a basic documentary …
