Cryptosporidium macropodum n. sp is described. Oocysts of C. macropodum from the feces of kangaroos (Macropus spp.) are morphologically indistinguishable from other mammalian Cryptosporidium species, including C. parvum, C. hominis, C. suis, and C. canis. The oocysts are fully sporulated on excretion, lack sporocysts, and have an average width of 4.9 microm (4.5-6.0), a length of 5.4 microm (5....

Flavonoids are secondary metabolites produced mainly in almost all terrestrial plants and fruits,where they provide UV protection and color. They have a fused ring system consisting of an aromaticring and a benzopyran ring with a phenyl substituent. Their biological activities have an impact onhuman health so that they serve as target molecules to develop new drugs. From methanolic extractof ae...

The alpine ecosystem is the only terrestrial biogeographic unit that is distributed globally. Studying phylogenetics of the plant species in this widespread ecosystem can provide insights into the historical biogeographic processes that have shaped the global biodiversity. The trans-Pacific disjunct alpine genus Oreomyrrhis (Apiaceae) was investigated using nrDNA ITS sequences to test the taxon...

introduction & aim: plant growth regulators (pgr) have same effect as natural plant's hormones and can change the main components in plant samples. chaerophyllum aureum l. is related to apiaceae family. experimental: in this paper the qualitative and quantitative composition of the volatile oils of ‎chaerophyllum aureum l. were reported after using different concentrations of iaa and naa ‎...

Sub-aerial parts of Chaerophyllum aureum L. yielded two polyacetylenes, falcarinol (1), falcarindiol (2), three lignans, namely nemerosin (3), deoxypodorhizone (4), deoxypodo-phyllotoxin (5), two phenylpropanoids, 1'-hydroxymyristicin (6) and its angeloyl ester (7). Compounds 6 and 7 were isolated for the first time from plant material and their structures were elucidated by means of extensive ...
