Diversidade de abelhas (Hymenoptera: Apoidea) em mata de araucária em Santa Catarina

Visando conhecer a apifauna existente em floresta ombrófila mista, realizou-se estudo em duas áreas de mata de araucária em Mafra (SC), de setembro de 2016 a agosto de 2017. Foi amostrado um total de 1.304 indivíduos de 56 táxons, 32 gêneros e cinco subfamílias. Índices de diversidade e equabilidade foram calculados. As plantas visitadas somam 48 espécies de 16 famílias. Asteraceae foi visitada com mais frequência (41,7% dos táxons). Abelhas dos táxons Meliponini, Ceratinini e Halictinae foram prevalentes. A sequência de predominância de subfamílias quanto à diversidade (Apinae seguida de Halictinae) seguiu o padrão transicional entre porções subtropicais e temperadas da região neotropical, com pequeno número de espécies abundantes e alta proporção de singletons, assim como variação sazonal. Apis mellifera correspondeu, em abundância, a 36,34%. A variação dos índices revelou diferença entre as duas áreas em relação à abundância, dominância e riqueza das espécies, evidenciando influência da antropização e sucessão ecológica. A diversidade e a abundância de abelhas estão diminuídas em comparação a estudos anteriores em ambientes próximos ou similares

ProtozoaDB: dynamic visualization and exploration of protozoan genomes

ProtozoaDB (http://www.biowebdb.org/protozoadb) is being developed to initially host both genomics and post-genomics data from Plasmodium falciparum, Entamoeba histolytica, Trypanosoma brucei, T. cruzi and Leishmania major, but will hopefully host other protozoan species as more genomes are sequenced. It is based on the Genomics Unified Schema and offers a modern Web-based interface for user-friendly data visualization and exploration. This database is not intended to duplicate other similar efforts such as GeneDB, PlasmoDB, TcruziDB or even TDRtargets, but to be complementary by providing further analyses with emphasis on distant similarities (HMM-based) and phylogeny-based annotations including orthology analysis. ProtozoaDB will be progressively linked to the above-mentioned databases, focusing in performing a multi-source dynamic combination of information through advanced interoperable Web tools such as Web services. Also, to provide Web services will allow third-party software to retrieve and use data from ProtozoaDB in automated pipelines (workflows) or other interoperable Web technologies, promoting better information reuse and integration. We also expect ProtozoaDB to catalyze the development of local and regional bioinformatics capabilities (research and training), and therefore promote/enhance scientific advancement in developing countries

Pitfalls and complications in the treatment of cervical spine fractures in patients with ankylosing spondylitis

Patients with ankylosing spondylitis are at significant risk for sustaining cervical spine injuries following trauma predisposed by kyphosis, stiffness and osteoporotic bone quality of the spine. The risk of sustaining neurological deficits in this patient population is higher than average. The present review article provides an outline on the specific injury patterns in the cervical spine, diagnostic algorithms and specific treatment modalities dictated by the underlying disease in patients with ankylosing spondylitis. An emphasis is placed on the risks and complication patterns in the treatment of these rare, but challenging injuries
