EL AFLORAMIENTO COSTERO Y EL FENÓMENO DE EL NIÑO: IMPLICACIONES SOBRE LOS RECURSOS BIOLÓGICOS DEL PACIFICO DE PANAMÁ

The Panamanian Pacific is under the influence of natural environmental changes, such as the coastal upwelling and manifestation of El Niño. These events can have severe implications for the biological resources. In this study we characterized the hydrological changes in the Gulf of Panama as related to their seasonality and annual variability. The intensity of the upwelling was assessed using sea surface temperature data. We also evaluated the coral genetic diversity for the coral Pocillopora damicornis. There were obvious changes in the hydrological and biological parameters monitored in the Gulf of Panama as result of the upwelling. The historical analysis of upwelling in the Gulf of Panama indicated that the upwelling occurs in pulses related to sea surface temperatures. In conclusion, sea surface temperature is the best quantitative estimate of upwelling intensity in the Gulf of Panama. The electrophoretic analysis of isozymes in the coral Pocillopora damicornis in Panama suggest the existence of a wider genetic diversity in the thermically stable water of the Gulf of Chiriquí and in areas of moderate upwelling such as Iguana Island in the Gulf of Panama. This contrast with the limited genotypic diversity found in areas of strong upwelling such as the Pearl Islands and the Panama Bay.  La costa del Pacífico panameño está bajo la influencia de cambios ambientales naturales, como el afloramiento costero y las manifestaciones del fenómeno de El Niño, que tienen implicaciones sobre los recursos biológicos. Durante este estudio se caracterizaron las variaciones hidrológicas estacionales e interanuales en el Golfo de Panamá, se estimó la intensidad del afloramiento utilizando los datos de la temperatura superficial del mar y se evaluó preliminarmente la diversidad genotípica de los corales. Se observaron cambios notables en la calidad del agua en el Golfo de Panamá como consecuencia del afloramiento. El análisis histórico de los afloramientos en el Golfo de Panamá indica que éstos son pulsativos y con más de dos períodos y asociados a las temperaturas superficiales del mar. La temperatura representa el mejor estimado cuantitativo de la intensidad de afloramiento periódico en el Golfo de Panamá. El análisis electroforético de las isoenzimas del coral Pocillopora damicornis en Panamá sugiere la existencia de una amplia diversidad genética en las áreas térmicamente estables del Golfo de Chiriquí y en áreas de afloramiento moderado como Isla Iguana en el Golfo de Panamá. Lo anterior contrasta con la limitada diversidad de genotipos que tiene la especie en las áreas con fuerte influencia del afloramiento, como en el Archipiélago de Las Perlas y en las islas de la Bahía de Panamá

Elysiapyrones from Elysia diomedea. Do such metabolites evidence an enzymatically assisted electrocyclization cascade for the biosynthesis of their bicyclo[4.2.0]octane core?

4 pages, 1 figure, 1 scheme.-- PMID: 15673253 [PubMed].-- Printed version published Feb 3, 2005.Supporting information (Spectral data and experimental procedures) available at: http://pubs.acs.org/doi/suppl/10.1021/ol0477428Biogenetically interesting polypropionate-derived metabolites 1 and 2, featuring an unprecedented skeleton, have been isolated from the sea slug Elysia diomedea. Their enantiomeric character indicates that the current spontaneous electrocyclization cascade biogenetic hypothesis for the bicyclo[4.2.0]octane core must be enzymatically aided. These compounds are isomeric with the 15-nor-9,10-deoxytridachione/15-norphotodeoxytridachione pair of metabolites and encourage speculation about their biosynthetic relationship.This work was supported by the MEC (PPQ2002-02494) and the Canary Islands Government (PI2002/044).

The C-12 oxygenated function, characteristic of the coral cyclopentanone fatty acid derivatives, is involved in the formation of a five-membered oxane ring fused to the cyclopentane network. Its structure and stereochemistry were determined on the basis of spectral studies and molecular mechanics calculations.This work was supported by the MCYT (PPQ2002-02494), DGUI of the Canary Islands Government (PI2002/044) and CYTED.

Exercise capacity in a child with McArdle disease

We report the exercise capacity of an 8-year-old boy with clinical, histological, biochemical, and genetic evidence of McArdle disease. The patient presented with severe myalgia, proteinuria, hematuria, pyrexia, and elevated creatine kinase after swimming. After pre-exercise ingestion of sucrose, he performed treadmill exercise to symptom limitation. His peak oxygen uptake (18.8 mL/kg/min) and ventilatory threshold (16.0 mL/kg/min) were reduced by 40% and 20% compared with healthy age-matched and gender-matched controls. The results suggest that exercise capacity is reduced early in life in patients with McArdle disease and suggest the need for prophylactic exercise training (following pre-exercise feeding to prevent rhabdomyolysis) to minimize deconditioning.Sin financiación1.240 JCR (2007) Q3, 106/143 Clinical neurology, 41/78 PediatricsUE
