Results from on-the-ground efforts to promote sustainable cattle ranching in the Brazilian Amazon

Agriculture in Brazil is booming. Brazil has the world’s second largest cattle herd and is the second largest producer of soybeans, with the production of beef, soybeans, and bioethanol forecast to increase further. Questions remain, however, about how Brazil can reconcile increases in agricultural production with protection of its remaining natural vegetation. While high hopes have been placed on the potential for intensification of low-productivity cattle ranching to spare land for other agricultural uses, cattle productivity in the Amazon biome (29% of the Brazilian cattle herd) remains stubbornly low, and it is not clear how to realize theoretical productivity gains in practice. We provide results from six initiatives in the Brazilian Amazon, which are successfully improving cattle productivity in beef and dairy production on more than 500,000 hectares of pastureland, while supporting compliance with the Brazilian Forest Code. Spread across diverse geographies, and using a wide range of technologies, participating farms have improved productivity by 30-490%. High-productivity cattle ranching requires some initial investment (R$1300-6900/ha or US$410-2180/ha), with average pay-back times of 2.5-8.5 years. We conclude by reflecting on the challenges that must be overcome to scale up these young initiatives, avoid rebound increases in deforestation, and mainstream sustainable cattle ranching in the Amazon.E.K.H.J.zE was funded by BBSRC grant BB/J014540/1 and the Tim Whitmore 215 Trust Fund

Megaíleo chagásico: Descrição de um caso

É apresentado um caso de megaíleo de natureza chagásica. O paciente, portador da Doença de Chagas, branco com 41 anos, apresentava história de 3 anos de episódios de eólicas abdominais, distensão e diarréia, que foram se tornando mais intensas e mais freqüentes. Fora das crises, apresentava-se assintomático. O diagnóstico de megaíleo foi estabelecido por meio do estudo radiológico contrastado do intestino delgado. O estudo histológico realizado em fragmento obtido à intervenção cirúrgica mostrou diminuição do número de células ganglionares dos plexos mientéricos

Spettrometria di massa e risonanza magnetica nucleare protonica per la determinazione di acidi biliari.

In questo articolo, dopo aver messo in evidenza le varie tecniche usate nell'analisi qualitativa e quantitativa di acidi biliari, vengono passate in rassegna due delle principali metodologie analitico-strutturali in uso per la loro determinazione: la spettrometria di massa e la risonanza magnetica nucleare protonica

Lipid composition of wild Ecuadorian Theobroma subincanum Mart. seeds and comparison with two varieties of Theobroma cacao L.

The present work analyzes the lipid fraction from seeds of wild Ecuadorian Theobroma subincanum and selected commercial varieties of Theobroma cacao from Mexico (var. Criollo) and Ecuador (var. Arriba). The lipid fraction was obtained from the seeds through supercritical fluid extraction and analysis performed by preparatory thin-layer chromatography followed by gas chromatography. The results revealed that in T. subincanum the triglycerides contain fatty acids with longer chains. The melting point and peroxide and saponifiable numbers were determined for each Theobroma sample. The results lead to the conclusion that T. subincanum would produce a poorer quality butter than T. cacao. Nevertheless, the results do point toward a significant commercial use of T. subincanum for low-profile products

Mixed oxo-hydroxy bile acids as actual or potential impurities in ursodeoxycholic acid preparation: a 1H and 13C NMR study

Some distinctive unprecedented described 1H NMR signals and the complete 13C NMR resonances are assigned for the entire set of mixed oxo-hydroxy bile acid isomers, obtained by selective oxidation of the hydroxy groups at position (3,7), (3,12) and (3,7,12) of chenodesoxycholic acid, desoxycholic acid and cholic acid, respectively. Partially or totally oxidized products are the major actual or potential impurities formed during the preparation of the pharmaceutically active ursodeoxycholic and chenodeoxycholic acids

ADESIONE DEGLI IMMIGRATI AL TEST MANTOUX PRESSO L’AZIENDA ULSS 5 POLESANA DI ROVIGO: ANALISI DELLE CRITICITÀ E POSSIBILI SOLUZIONI.

L’infezione tubercolare latente negli immigrati irregolari rappresenta un serio problema di sanità pubblica nel nostro Paese. Per tale motivo, l’Azienda ULSS 5 Polesana di Rovigo, secondo lo specifico protocollo operativo della Regione Veneto, effettua lo screening della tubercolosi che prevede l’esecuzione sistematica del test Mantoux a tutti gli immigrati ospitati nelle strutture di accoglienza del proprio territorio. Lo scopo di questo studio è valutare l’adesione tra gli immigrati irregolari all’esecuzione del test Mantoux e alla successiva lettura
