Measurements of the submicron fraction of the atmospheric aerosol in the marine boundary layer were performed from January to March 2007 (Southern Hemisphere summer) onboard the French research vessel Marion Dufresne in the Southern Atlantic and Indian Ocean (20 S–60 S, 70 W–60 E). We used an Aerodyne HighResolution-Time-of-Flight AMS to characterize the chemical composition and to measure spec...

Multiplication-stimulating activity (MSA) is the name given to a family of polypeptides with a molecular weight of approximately 10,000 that have been isolated from the culture medium of a rat liver cell line. MSA stimulates growth and DNA synthesis in chick embryo fibroblasts and has weak insulin-like metabolic activity. We have purified MSA and characterized the binding of ‘““I-labeled MSA to...

Multiple system atrophy (MSA) is an adult-onset neurodegenerative disorder that has both clinical and pathological variants. Clinical examples include MSA with predominant cerebellar ataxia (MSA-C) and MSA with predominant parkinsonism (MSA-P), whereas olivopontocerebellar atrophy and striatonigral degeneration represent pathological variants. We performed systematic reviews of studies that add...

Multiple Sequence Alignment (MSA) is a fundamental tool of bioinformatics. Row-Column MSA (RC-MSA) methods such as CLUSTALW [12] produce tabular alignments that are now familiar. However, these methods have a number of shortcomings, including difficulty of understanding the result, high computational complexity, questionable assumptions, and other artifacts (such as poor handling of prefixand s...

This paper deals with building linguistic resources for Gulf Arabic, one of the Arabic variations, for sentiment analysis task using machine learning. To our knowledge, no previous works were done for Gulf Arabic sentiment analysis despite the fact that it is present in different online platforms. Hence, the first challenge is the absence of annotated data and sentiment lexicons. To fill this g...

BACKGROUND AND PURPOSE Accurate diagnosis of Atypical Parkinsonian Syndromes (APS) is important due to differences in prognosis and management, but remains a challenge in the clinical setting. The purpose of our meta-analysis was to identify characteristic patterns of gray matter atrophy in Corticobasal Degeneration (CBD), Progressive Supranuclear Palsy (PSP), Multisystem-Atrophy Parkinsonian t...
