Sarcocystis is an obligatory intracellular protozoan parasite which can infect humans and animals. Sheep are intermediate hosts of four Sarcocystis species: Sarcocystis tenella, Sarcocystis gigantea, Sarcocystis arieticanis, and Sarcocystis medusiformision. The purpose of the study was to determine the molecular identification of the macroscopic and microscopic cysts of Sarcocystis in sh...

The traps of Byblis gigantea are active, because after capturing a digestible particle (prey) it changes its position so that rests on the surface with digestive glands.

BACKGROUND Calotropis gigantea (Asclepiadaceae) (Niu jiao gua) has been used as a poultice in Chinese medicine for treating inflammatory skin diseases, e.g., neurodermatitis. This study aims to isolate the epidioxysterols from the flowers of C. gigantea, elucidate their structures and evaluate their possible inhibitory effects on the NF-κB pathway. METHODS The two epidioxysterols 9,11-dehydro...

SYNOPSIS. Host shifts and subsequent host-race formation likely play a more common role in the speciation of herbivorous insects than has generally been recognized. Our studies of the interactions of goldenrod host plants (Solidago: Compositae), the gall fly Eurosta solidaginis (Diptera: Tephritidae), and the stemand gall-boring Mordellistena convicta (Coleoptera: Mordellidae) provide behaviora...
