background: treatment of cancer patients using conventional chemotherapy causes serious side effects and, at best, merely extends the patient’s lifespan by a few years. the potential of alternative therapies may therefore be of great benefit in cancer control. the effect of trigonella foenum graecum seed extract has been previously reported on some neoplastic cells. here, its effect is evaluate...

Ageniella Banks, 1912 is a paraphyletic group exclusive to the Nearctic and Neotropical regions. The genus has remarkable morphological diversity among species strong sexual dimorphism, hampering taxonomic studies of it. Herein, we add two new fauna Ageniella: A. caerulea sp. nov. belonging subgenus Ameragenia ruschi Priophanes; both are described illustrated. A brief discussion subgeneric char...

Efficacy of some local plants in the management of Aspergillus flavus and aflatoxin contamination was investigated. Aqueous extracts of rhizome of Zingiber officinalis and leaf extracts of Trigonella foenum-graecum inhibited aflatoxin production to a significant level. While solvent extracts of Zingiber officinalis and Oxalis corniculata could suppress both the growth and aflatoxin production b...

Currently, >35 Saudi Arabian medicinal plants are traditionally used for various liver disorders without a scientific rationale. This is the first experimental evaluation of the anti-hepatitis B virus (HBV) potential of the total ethanolic and sequential organic extracts of 60 candidate medicinal plants. The extracts were tested for toxicity on HepG2.2.15 cells and cytotoxicity concentration (C...

Like many other species of petrel, blue petrel (Halobaena caerulea) are able to return to their nest burrows at night in complete darkness. Since petrels have a well-developed olfactory system, we carried out an experiment to test whether blue petrels use olfaction to localise their nest burrows. Incubating birds were injected intranasally with a zinc sulphate solution, which reversibly impairs...

Australia and New Guinea (together referred to as Sahul) were linked by land for much of the late Tertiary share many biotic elements. However, is dominated rainforest, northern savannah. Resolving patterns interchange between these two regions critical understanding expansion contraction both habitat types. The green tree frog (Litoria caerulea) has a vast range across eastern Guinea. An asses...
