Identification of bioactive molecules and their targets impedes the process of drug development. In a recent paper, a genetically tractable organism, the Caenorhabditis elegans worm, is shown to be a viable screening system in which the drug target and the pathway it activates can be readily identified.

Bioinorganic medicinal chemistry remains a hot field for research aimed at developing novel anti-cancer treatments. Discovery of metal complexes as potent antitumor chemotherapeutics such as cisplatin led to a significant shift of focus toward organometallic/ bioinorganic compounds containing transition metals and their chelates as novel scaffolds for drug discovery. In that way, transition met...

Background: Pulmonary nodular excavation should firstly evoke tuberculosis or necrosis broncho-pulmonary tumor, particularly: epidermoid carcinoma. The case discussed here illustrated these difficulties in patients with rheumatoid arthritis (RA). Case Presentation: A 63-year-old woman was presented with a-three-year history of RA and a recent discovery of an excavated pulmonary nodule. Initi...

The view that perception is direct holds that a perceiver is aware of or in contact with ordinary mind-independent objects, rather than mind-dependent surrogates thereof. In this paper I try to articulate an account of direct perception from a Gibsonian point of view, located within the wider terrain of cognitive science and psychology. James Gibson's ecological theory proposes that perception ...
