An introduction to the systematics of Akodon orophilus Osgood, 1913 (Rodentia: Cricetidae) with the description of a new species.

The genus Akodon is one of the most species-rich rodent lineages in South America. In Peru, this genus contains 14 species subdivided in two groups: aerosus and boliviensis. Akodon orophilus Osgood, 1913 (Rodentia: Cricetidae) is a member of the Akodon aerosus group that inhabits the northern Peruvian montane forest, but is poorly characterized and its distribution is vaguely known.

[Potential use of snake venom components in cancer treatment].

Cancer can develop to the extent tumor cells grow, divide and grow into other body tissues. Integrins are a family of cell-surface heterodimeric receptors that play an important role in the development of tumor angiogenesis, growth and metastasis, thus being recognized as an attractive therapeutic target. Snake venom contains low-molecular weight peptides known as "disintegrins" that bind to integrins with high affinity, and prevent their action in cancer.

[Experimental efficacy of IgY antibodies produced in eggs against the venom of the Peruvian snake Bothrops atrox].

Objectives: To develop an immunization protocol in order to produce avian IgY immunoglobulins against Bothrops atrox Peruvian snake venom and to evaluate its neutralizing capacity.

Materials And Methods: Six Hy Line Brown hens were immunized each two weeks using 500μg/doses of B. atrox venom in a period of two months.
