BACKGROUND Breakdown of humoral tolerance to RBC antigens may lead to autoimmune hemolytic anemia, a severe and sometimes fatal disease. The underlying mechanisms behind the breakdown of humoral tolerance to RBC antigens are poorly understood. DESIGN AND METHODS In order to study the pathogenesis of autoimmune hemolytic anemia, we developed a murine model with RBC-specific expression of a mod...

Spartina alterniflora Loisel. is one of the most invasive species in the world. However, little is known about the role of artificial mowing in its invasiveness and competiveness. In this work, we studied the effect of mowing on its interspecific interactions with native species Phragmites australis (Cav.) Trin ex Steud of the Yangtze Estuary, China. We calculated their relative neighbor effect...

Rhizobacterial communities associated with Phragmites australis (Cav.) Trin. ex Steud. in a hypersaline pond close to Wuliangsuhai Lake (Inner Mongolia - China) were investigated and compared with the microbial communities in bulk sediments of the same pond. Microbiological analyses have been done by automated ribosomal intergenic spacer analysis (ARISA) and partial 16S rRNA gene 454 pyrosequen...

The aim of this study was to evaluate the physicochemical and functional properties of the protein recovered from mechanically deboned chicken meat (MDM) obtained by surimi and pH shift processes. The final products were characterized for proximate chemical composition with the protein isolate show in low value of lipids and a higher value of proteins than the surimi. Among these proteins, frac...

A new strain of avian picornavirus was identified in fecal samples from broiler chickens in a commercial farm in the municipality of Benevides, Pará, Brazil. Genomic analysis showed it to have a nucleotide identity of 78.4% with the family Picornaviridae, genus Avisivirus, and species Avisivirus A, suggesting that this is a possible new strain within this species.

We have performed muon spin relaxation and susceptibility measurements of CaV4O9 and CaV2O5, systems in which spin gap-like behavior has been found. We observe spin freezing in the two compounds below 12 K and 50 K, respectively. Our results indicate the possibility that a substantial fraction of the vanadium magnetic moment is not in a spin singlet state at low temperatures in either material....
