Stent assisted coiling (SAC) is a useful technique for the treatment of wide necked complex aneurysm. As the frequency of SAC increases, stent-related complications such as thromboembolism, aneurysm rupture, and vessel rupture have been reported. However, to the best of our knowledge, carotid-cavernous fistula (CCF) after SAC has never been reported. The authors experienced a case of direct CCF...

Rice is a staple food for more than half of the world’s population. Modern rice varieties have been developed high yield and quality; however, there has substantial loss diversity. A greater number genetically dynamic landraces could offer valuable useful genetic resources improvement. In this study, diversity population structure 365 accessions lowland upland from four populations different ge...

Soil microorganisms play the important role in driving biogeochemical cycles. However, it is still unclear on soil microbial community characteristics and mechanism rhizosphere bulk soils of different halophyte species. In this study, we analyzed bacterial communities three typical halophytes Yellow River Delta, i.e., Phragmites communis , Suaeda salsa Aeluropus sinensis by high-throughput sequ...

Abstract Galls, neo-formed plant structures that can occur in different organs, are generated by species-specific interaction with an inducing organism. Inducers manipulate the metabolism of its host. Microgramma vacciniifolia (Langsd. & Fisch.) Copel. is a Neotropical epiphytic fern hosted two stem galls, one induced midge species (Diptera) and other micromoth (Lepidoptera). The aim this s...

AIM Increasing use of surgical magnification for operations in the territory of the anterior choroidal artery (AChA) has created a need for detailed knowledge of their anatomical variations. The aim of the present study is to examine the anatomical variations of the AChAin patients operated via pterional approach. MATERIAL AND METHODS The origin and branching pattern of AChAs were observed in...

Vertebrate gut microbiome often underpins the metabolic capability and provides many beneficial effects on their hosts. However, little was known about how host trophic level influences fish gut microbiota and metabolic activity. In this study, more than 985,000 quality-filtered sequences from 24 16S rRNA libraries were obtained and the results revealed distinct compositions and diversities of ...
