Many secreted signaling molecules are synthesized as precursors that undergo multiple maturation steps to generate their mature forms. The Saccharomyces cerevisiae mating pheromone a-factor is a C-terminally isoprenylated and carboxylmethylated dodecapeptide that is initially synthesized as a larger precursor containing 36 or 38 amino acids. We have previously shown that the maturation of a-fac...
Background Patients with progressive multiple sclerosis (MS) often have cognitive impairment in addition to physical impairment. The burden of cognitive and physical impairment progresses over time, and may be major determinants of quality of life. The aim of this study was to assess to which degree quality of life correlates with physical and cognitive function in progressive MS. Methods Thi...
BACKGROUND T2 Lesion Volume (T2LV) has been an important biomarker for multiple sclerosis (MS). Current methods available to quantify lesions from MR images generally require manual adjustments or multiple images with different contrasts. Further, implementations are often not easily or openly accessible. OBJECTIVE We created a fully unsupervised, single T2 FLAIR image T2LV quantification pac...
The present study investigates, the synthesis of new derivatives of benzenesulfonamide nucleus hybridized with various substituted pyrazole 4, 8 and thiazole ring 6 using 4-amino-N-butylbenzenesulfonamide 1 as the key starting compound. Furthermore, 3,5-diaminopyrazole derivative 10 was allowed to react with different reagents such as an active methylene compounds, ketone dithioacetal, ethoxyme...
