The True Identity of the New World Iguanid Lizard Müller and Hellmich 1932 (Iguania: Liolaemidae) and Description of a New Species in the Group.

is a particularly species-rich radiation of New World iguanid lizards from southern South America. Thanks to intense systematic and taxonomic research, the knowledge on its species- level diversity has increased rapidly over the past several years. The species-complex has received considerable attention and a remarkable case is , a name that has been used for two different species that are sympatric in Termas de Chillán, central Chile.

Two new lizards from the Andean highlands of Southern Chile (Squamata, Iguania, Liolaemidae).

is a diverse genus of lizards, subdivided into two subgenera: () and , distributed mainly in Chile and Argentina. The complex is the most diverse group within (), especially the species closely related to , which form a clade currently comprising nine species. Several Chilean species of this group have been recently described, mainly from volcanoes and poorly explored mountains.

Two new species of the Liolaemuselongatus-kriegi complex (Iguania, Liolaemidae) from Andean highlands of southern Chile.

The elongatus-kriegi complex is one of the most diverse clades of the Liolaemus (sensu stricto) subgenus of lizards. There are currently 29 species recognized in this group distributed between Chile and Argentina. Based on molecular evidence, there seem to be five main clades nested within this complex: the elongatus, leopardinus, kriegi, petrophilus and punmahuida clades.

Effect of the standardized Cimicifuga foetida extract on Hsp 27 expression in the MCF-7 cell line.

Cimicifuga foetida, an Asian Cimicifuga species, has been employed as a cooling and detoxification agent in traditional Chinese medicine since ancient times. For this herb, two cycloartane triterpene glycosides isolated from the rhizomes have demonstrated cytotoxicity on rat tumor and human cancer cell lines. Since human Hsp27 is increased in various human cancers and exhibits cytoprotective activity that affects tumorigenesis and the susceptibility of tumours to cancer treatment, the purpose of this research was to study the expression of this protein in MCF-7 breast cancer cells.
