Bragantia, Campinas, v. 75, n. 2, p.199-211, 2016 AbstrAct: Mango wilt, caused by Ceratocystis fimbriata, is one of the most important diseases affecting mango yields in Brazil. Information regarding the biochemical mechanisms involved in mango resistance against C. fimbriata is absent in the literature. Thus, the present study determined and quantified alkaloids and phenolics in the stem tissu...

Previous work has shown that the peptide-like growth factor strepogenin probably occurs in certain proteins such as insulin and trypsinogen at the amino end of the protein (l), and that it is liberated by suitable enzymic digestion. This conclusion suggested a means for attacking the almost insurmountable task involved in separating the one compound strepogenin from the mixture of numerous pept...

BACKGROUND Hair is susceptible to exogenous sources of discoloration. There are several exogenous etiologies for yellow hair discoloration, including tobacco. PURPOSE We describe the clinical features of five men with tobacco-associated yellow discoloration of their mustache, a condition known as "smoker's mustache." We also review the characteristics of men with tobacco-associated yellow dis...

BCR-ABL1-specific tyrosine kinase inhibitors prolong the life of patients with chronic myeloid leukemia (CML) but cannot completely eradicate CML progenitors. The BH3 mimetic, ABT-263, targets prosurvival BCL2 family members, and has activity against CML progenitors. However, the inhibitory effect of ABT-263 on BCL-XL, which mediates platelet survival, produces dose-limiting thrombocytopenia. A...

Milk samples were collected in early lactation (8–14 days milk; DIM) and late (199–326 from 11 cows to assess the differences bovine milk fatty acid (FA) triacylglycerol (TAG) composition, FA positional distribution TAG structure, solid fat content (SFC). Cows that negative energy balance, mobilised C16:0, C18:0, C18:1cis9 their body stores, increasing concentrations of these fat. These high C1...

THE photosensitive substancecontained -in the -rods of the eyes of ve#tebrates, visual purple, is a chromoprotein, i.e. a protein to which one or more chromophores are attached. Aqueous solutions of visual puirple are-decomposed by light to give an unstable compound "transient orange", which in turn bleaches thermally to "indicator yellow" [Lythgoe, 1937]. Indicator yellow may also be formed wi...

Although a highly effective vaccine is available, the number of yellow fever cases has increased over the past two decades, which highlights the pressing need for antiviral therapeutics. In a high throughput screening campaign, we identified an acetic acid benzodiazepine (BDAA) compound, which potently inhibits yellow fever virus (YFV). Interestingly, while treatment of YFV infected cultures wi...

THE CLASSIC ESTIMATION OF UREA IN THE BLOOD, while not technically difficult, is time consuming, and a quicker method was sought for an emergency procedure. It has been known for many years that a solution of xanthydrol with urea forms an insoluble precipitate, dixanthylurea. Also that this precipitate dissolves in 50% sulfuric acid to give an intense yellow-colored solution which obeys Beer’s ...
