Background: Allergy is a clinical disorder affecting humans worldwide. Allergenic extracts prepared from natural source materials remain heterogeneous in composition and content, but are regularly used for diagnosis and immunotherapy. Recombinant allergens are suitable candidates to use in place of natural allergens; however, the recombinant allergens should be assessed and compared with the na...

Frustrated Lewis pairs (FLPs) have evolved from a revolutionary concept to widely applied catalysts. We recently reported the ring-expanded N-heterocyclic carbene supported copper(I) boryliminomethanide, (6-Dipp)CuC(=NtBu)Bpin and noted it reacted with heterocumulenes in fashion reminiscent of FLPs. thus set out explore its reactivity range other substrates known react This was undertaken by se...

The tremendous diversity of leaf shapes has caught the attention of naturalists for centuries. In addition to interspecific and intraspecific differences, leaf morphologies may differ in single plants according to age, a phenomenon known as heteroblasty. In Arabidopsis thaliana, the progression from the juvenile to the adult phase is characterized by increased leaf serration. A similar trend is...

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...

During malolactic fermentation (MLF) in grape must and wine, heterofermentative lactic acid bacteria may degrade arginine, leading to the formation of ammonia and citrulline, among other substances. This is of concern because ammonia increases the pH and thus the risk of growth by spoilage bacteria, and citrulline is a precursor to the formation of carcinogenic ethyl carbamate (EC). Arginine me...

A mixture of copper complex and Al/CuO nanothermite, Al/CuO/CuC, represents one the state-of-the-art gas-generating thermite systems with various pyrotechnic applications due to its tunable gas release rates. The reactivity reactive inks loadings poly(vinylpyrrolidone) (PVP) binder mixed Al/CuO/CuC is characterized using high-speed imaging diagnostics pressure measurements. For a PVP mass fract...

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...
