Background. Sarcomatoid variant of urothelial carcinoma (SVUC) was added to the WHO classification in 2004. Aims. To review the literature. Materials and Method. Various internet databases were used. Result. SVUCs are rare biphasic malignant neoplasms exhibiting morphologic/immunohistochemical evidence of epithelial and mesenchymal differentiation with the presence or absence of heterologous el...

Protease activities in allergen sources are thought to be involved in triggering allergic inflammation through the disruption of epithelial barrier or the induction of proinflammatory cytokines. Protease allergens may also work as type 2 helper T cell (TH2) adjuvants through the cleavage of cell surface receptors. Here, we report molecular cloning and immunochemical characterization of a new Ja...

The article proposes a modified Design-Based Research (DBR) framework which accommodates the various socio-cultural factors that emerged in the longitudinal PA-HELP research study at Central University College (CUC) in Ghana, Africa. A transnational team of stakeholders from Ghana, Canada, and the USA collaborated on the development, implementation, and subsequent modification of the DBR framew...

A constante avaliação do desempenho dos sistemas de irrigação torna-se necessária para verificar se as condições previstas no projeto condizem com o observado em campo. Desta forma, objetivou-se avaliar localizada visando a indicar medidas uniformidade. O trabalho foi conduzido na Fazenda Areião, área experimental da ESALQ/USP, Piracicaba/SP, cultivada maracujá. baseou-se nos seguintes coeficie...

The tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite begomovirus (genus Begomovirus, family Geminiviridae) that was originally isolated in India, but has become serious threat to various horticultural crops the Indian subcontinent, Southeast Asia, East Middle East, and western Mediterranean Basin. In Basin, ToLCNDV caused huge economic damage cucurbit (cucumber, melon, squash, zucchini...

Diversity in leaf shape is produced by alterations of the margin: for example, deep dissection leads to leaflet formation and less-pronounced incision results in serrations or lobes. By combining gene silencing and mutant analyses in four distantly related eudicot species, we show that reducing the function of NAM/CUC boundary genes (NO APICAL MERISTEM and CUP-SHAPED COTYLEDON) leads to a suppr...
