The purpose of this study was to determine if the exotic venomous species, Pterois volitans (lionfish) had reached as far south as St Vincent in the Caribbean. This predatory marine fish has successfully invaded the waters of the Western Atlantic and the Caribbean. Such success as an exotic invasive species is rare for a predatory marine fish. It is possible that the fish are growing larger and spreading faster than anticipated, thanks to a lower burden of parasites and a paucity of natural predators in their new environment. But prior to this report, no sightings of this species this far south had been reported. ⋯ The exotic predatory and venomous red lionfish, Pterois volitans, has successfully invaded marine waters as far south as the Windward Islands. Fishermen in these regions should be aware of this venomous species in the region and physicians must be aware of how to manage stings from such animals.

This study investigates the change of endothelial cell morphology and function at the rabbit basilar bifurcations in response to sustained high blood flow after bilateral common carotid artery ligation. ⋯ This study is the first to present endothelial cell changes of basilar artery bifurcation in response to sustained high blood flow in rabbits. Endothelial cell impairment possibly initiates aneurysm formation.

Agaricus sylvaticus mushroom has been widely studied because of its high nutritional value and medicinal properties. The objective of this study was to evaluate the antioxidant potential of both alcoholic and aqueous extracts of Agaricus sylvaticusand quantify their total polyphenol content. The antioxidant activity was performed by the 2, 2-diphenyl-1-picrylhydrazyl radical scavenging capacity and total polyphenol content was assessed by colorimetric method. Observation also noted the great antioxidant potential of aqueous, alcoholic and ethereal extracts (14.6%, 75.6% and 14.6%, respectively) of the Agaricus sylvaticus mushroom, highlighting the alcoholic extract, which demonstrates the extraordinary benefits of this mushroom in the diet, since antioxidants prevent premature ageing and various types of cancer.

We report the case of a 45-year-old woman with a painless soft tissue mass on the left side of her neck. At surgery, the lesion was solid and rubbery and revealed gray-white fibrous areas. It was pathologically confirmed as an elastofibroma. ⋯ Elastofibroma arising from connective tissue and usually found in the subscapular region is extremely rare in the neck. The pathogenesis of elastofibroma is still unclear but increased mechanical stress or nutritional derangement consequent to vascular involvement and hereditary factors may predispose to this lesion. Marginal excision is the treatment of choice in symptomatic patients.
