Small colony variants (SCV) of Staphylococcus aureus have been reported as implicated in chronic infections. Here, we investigated the genomic and transcriptomic changes involved evolution from a wild-type to SCV patient with prosthetic joint infection relapse. The presented stable phenotype no classical auxotrophy emergence rifampicin resistance. Whole Genome Sequencing (WGS) analysis showed only loss 42.5 kb phage 3 deletions, among which one targeting rpoB gene, known be target associated...
Staphylococcus aureus bone and joint infection (BJI) is associated with significant rates of chronicity relapse. In this study, we investigated how S. able to adapt the human environment by comparing isolates from single patients persisting or relapsing BJIs that were recovered during initial recurrent BJI episodes. vitro in vivo assays whole-genome sequencing analyses revealed induced a reduced inflammatory response, formed more biofilms, persisted longer intracellular compartments host...
Este estudo realiza uma revisão aprofundada sobre a correção cirúrgica da ptose palpebral, abordando as principais técnicas empregadas, os materiais utilizados e desfechos clínicos observados. A pesquisa foi conduzida por meio de integrativa literatura, abrangendo artigos publicados entre 2010 2024, com o objetivo sintetizar melhores práticas inovações no manejo dessa condição oftalmológica. Os resultados apontaram que aponeurótica é forma mais prevalente, sendo tratada maior frequência como...
Proteasomes are intracellular complexes that control selective protein degradation in organisms ranging from Archaea to higher eukaryotes. These structures have multiple proteolytic activities required for cell differentiation, replication and maintaining cellular homeostasis. Here, we document the presence of 20S proteasome protist parasite Tritrichomonas foetus. Complementary techniques, such as a combination whole genome sequencing technologies, bioinformatics algorithms, fractionation...
SUMMARY Certain trypanosomatids co-evolve with an endosymbiotic bacterium in a mutualistic relationship that is characterized by intense metabolic exchanges. Symbionts were able to respire for up 4 h after isolation from Angomonas deanei . FCCP (carbonyl cyanide-4-(trifluoromethoxy)phenylhydrazone) similarly increased respiration wild-type and aposymbiotic protozoa, though higher maximal O 2 consumption capacity was observed the symbiont-containing cells. Rotenone, complex I inhibitor, did...
The costa is a prominent striated fibre that found in protozoa of the Trichomonadidae family present an undulating membrane. It composed primarily proteins have not yet been explored. In this study, we used cell fractionation to obtain highly enriched fraction whose structure and composition was further analysed by electron microscopy mass spectrometry.Electron negatively stained samples revealed costa, which periodic with alternating electron-dense electron-lucent bands, displays three...
SUMMARY Tritrichomonas foetus is a protist that causes bovine trichomoniasis and presents well-developed Golgi. There are very few studies concerning the Golgi in trichomonads. In this work, monoclonal antibodies were raised against of T. used as tool on morphologic biochemical organelle. Among produced, one was named mAb anti-Golgi 20.3, which recognized specifically complex by fluorescence electron microscopy. By immunoblotting antibody two proteins with 60 66 kDa identified putative...
O objetivo deste estudo é descrever os principais fatores associados ao prolongamento do tempo de internação idosos hospitalizados e sua repercussão no quadro clínico geral. método consiste em uma revisão integrativa realizada entre novembro dezembro 2024, com dados provenientes da Biblioteca Virtual Saúde, a seleção 10 artigos que atenderam aos critérios inclusão: completos, disponíveis forma gratuita, publicados português, inglês ou espanhol, recorte temporal dos últimos cinco anos. Os...
Text clustering is a theme that receiving considerable attention nowadays in areas such as text mining and information retrieval. A starting point for methods applied on unstructured document collection the creation of vector-space model usually known bag-of-words [1]. Documents are then described by matrix which happens to be huge extremely sparse due exceeding number terms describing set documents. Although several techniques can employed reduce this number, final figure still high thus...
