Snail “metabolic hormone” and snail parasite metabolism
Comparative Biochemistry and Physiology, 1970Abstract 1. 1. An acetone extract of the liver of the snail Biomphalaria sudanica and tryptamine stimulate oxygen uptake in the daughter sporocysts of an unknown plagiorchioid cercariae. 2. 2. The same extract stimulates oxygen uptake Schistosoma mansoni but does not affect lactic acid production or glucose uptake in these worms. 3.

A key advantage that semiconductor ring lasers have over Fabry-Perot (FP) devices for relatively high power applications, is that they do not suffer from Catastrophic Optical Damage (COD) to the cleaved facets of the device bar[1]. However, the directional coupler (DC) section in the ring geometry, equivalent to the facet conditions in a FP laser ...

The American Naturalist, 2019
In 2017, The American Naturalist celebrated its 150th anniversary. It was founded as a journal of natural history, yet it developed into an important vehicle of the evolutionary synthesis. During the early years of the journal and through much of the twentieth century, evolutionary theory was developed to explain the history of nature before humankind ...
