“…The enzymatic degradation of A. japonica TAG may have actively proceeded at the terminal phase because a terminal-phase eel, which is probably unable to feed 17,18 , should obtain energy for spawning from its internal tissue lipids. Different from other fish species 27,28 , unusually medium levels of dimethyl acetals DMA in muscle PE suggest that plasmalogen-type PE are biosynthesized in eel muscles similar to those in invertebrates such as mollusks 25,26 .…”

“…Bivalve membranes are similar to mammalian neuron membranes in that they are rich in DHA and have elevated levels of plasmalogens in general (Kraffe et al. 2004), particularly in the gills (Nevenzel et al. , 1985).…”

Summary The deleterious reactive carbonyls released upon oxidation of polyunsaturated fatty acids in biological membranes are believed to foster cellular aging. Comparative studies in mammals and birds have shown that the susceptibility to peroxidation of membrane lipids peroxidation index (PI) is negatively correlated with longevity. Long‐living marine molluscs are increasingly studied as longevity models, and the presence of different types of lipids in the membranes of these organisms raises questions on the existence of a PI–longevity relationship. We address this question by comparing the longest living metazoan species, the mud clam Arctica islandica (maximum reported longevity = 507 year) to four other sympatric bivalve molluscs greatly differing in longevity (28, 37, 92, and 106 year). We contrasted the acyl and alkenyl chain composition of phospholipids from the mitochondrial membranes of these species. The analysis was reproduced in parallel for a mix of other cell membranes to investigate whether a different PI–longevity relationship would be found. The mitochondrial membrane PI was found to have an exponential decrease with increasing longevity among species and is significantly lower for A. islandica. The PI of other cell membranes showed a linear decrease with increasing longevity among species and was also significantly lower for A. islandica. These results clearly demonstrate that the PI also decreases with increasing longevity in marine bivalves and that it decreases faster in the mitochondrial membrane than in other membranes in general. Furthermore, the particularly low PI values for A. islandica can partly explain this species’ extreme longevity.

“…Las membranas branquiales consisten en una variedad de proteínas funcionales embebidas en una doble capa de fosfolípidos. Estas capas poseen propiedades tanto hidrofóbicas como hidrofílicas (Nevenzel et al, 1985). Las branquias de crustáceos, de especies eurihalinas y estenohalinas, están diferenciadas generalmente, en estructura y función.…”

RESUMEN. Se evaluó la toxicidad del cobre, empleando sulfato de cobre en larvas nauplii sin alimentar del camarón comercial Artemesia longinaris mediante bioensayos de 72 horas de duración, con el objeto de determinar la dosis efectiva media o concentración letal (LC50) y grado de desarrollo (estadio larval). Se prepararon concentraciones de cobre equivalentes a 1000, 500, 250 y 125 partes por billón (ppb) en agua de mar (salinidad de 34 %). Un total de 90 larvas nauplii por tratamiento (tres réplicas de 30 larvas c/u) fueron acondicionadas en recipientes de vidrio con 300-500 ml de cada solución. Como control se empleó agua de mar con EDTA. Los resultados del test de toxicidad aguda mostraron una relación directa entre mortalidad y concentración de cobre. A una concentración de 1000 ppb, los nauplii mueren en menos de 24 hr. Los valores de LC50 para los diferentes períodos de los restantes tratamientos según el método de probits fueron: 660 ppb para 24 hr, 378,5 ppb para 48 hr y 212,3 ppb para 72 hr. La muda (crecimiento) de las larvas fue inhibida a concentraciones superiores a 125 ppb. En el «control», las larvas mudaron a protozoea a partir de las 72 hr y todas las larvas se encontraron en este estadio a las 96 hr.
