Título:  LC-ESI-IT-MS/MS and MALDI-TOF approach: identification of natural polymers from rhizophora mangle barks and determination of their analgesic and anti-inflammatory properties.

Conteúdo:  We recognize the chemical composition of the acetonic extract of Rhizophora mangle barks (AERM) using mass spectrometry analysis [liquid chromatography (LC)?ESI?IT-MS/MS and matrix-assisted laser desorption/ionization-time of flight-MS (MALDI-TOF)]. Analgesic activity was evaluated by formalin and tail-flick experimental assays. Anti-inflammatory activity was performed by paw edema test induced by carrageenan and 48/80 compounds. The first series of experiments involved [LC]?FIA?IT-MS/MS with 11 separated catechins derivatives until degree of polymerization 3 (DP3). The spectra obtained by MALDI-TOF analysis of the AERM presented two homologous series: one based on polymers of m/z 288 Da increments (up to DP12) and another series based on polymers of m/z [288 ? 162] Da increments (up to DP11). In addition to these series of flavan-3-ol, each DP had a subset of masses with a variation of - 16 Da (homologous series of afzelechins?m/z 873?3465 Da) and ? 16 Da (homologous series of gallocatechins?m/z 905?3497 Da). A similar pattern with homologous series of gallocatechins and afzelechins could also be observed for a fifth and a sixth monohexoside series: glucogallocatechins (m/z 779?3371) and glucoafzelechins (m/z 747?3339). The intraperitoneal administration of different doses of AERM (50, 150 and 300 lg mL-1) have a morphine-like effect and intense anti-inflammatory activity.

Título:  The potential distribution of invading Helicoverpa armigera in North America: Is it just a matter of time?

Conteúdo:  Helicoverpa armigera has recently invaded South and Central America, and appears to be spreading rapidly. We update a previously developed potential distribution model to highlight the global invasion threat, with emphasis on the risks to the United States. The continued range expansion of H. armigera in Central America is likely to change the invasion threat it poses to North America qualitatively, making natural dispersal from either the Caribbean islands or Mexico feasible. To characterise the threat posed by H. armigera, we collated the value of the major host crops in the United States growing within its modelled potential range, including that area where it could expand its range during favourable seasons. We found that the annual value of crops that would be exposed to H. armigera totalled approximately US$ 78 billion p.a., with US$ 843 million p.a. worth growing in climates that are optimal for the pest. Elsewhere, H. armigera has developed broad-spectrum pesticide resistance; meaning that if it invades the United States, protecting these crops from significant production impacts could be challenging. It may be cost-effective to undertake preemptive biosecurity activities such as slowing the spread of H. armigera throughout the Americas, improving the system for detecting H. armigera, and methods for rapid identification, especially distinguishing between H. armigera, H. zea and potential H. armigera x H. zea hybrids.
