Lycognathophis Boulenger, 1893 (Reptilia, Serpentes): Proposed Conservation

Redescription and geographical variation of Monopeltis guentheri Boulenger (Amphisbaenia, Reptilia)

The role of the vomeronasal organ of crotalines (Reptilia: Serpentes: Viperidae) in predator detection.

Most reptiles and mammals, with the exceptions of crocodilians, aquatic mammals and some primates, have a functional vomeronasal organ that detects and perceives semi-volatile chemicals in the environment. This organ is used in detection of prey and is also important for recognition of conspecifics and potential predators. We tested eight species of North American pit vipers for behavioural res...

Clinical, physiological and serological observations of a human following a venomous bite by Macrovipera lebetina lebetina (Reptilia: Serpentes).

A researcher, a 40 year-old male, was bitten on his finger accidentally by a 75 cm long, adult male blunt-nosed viper, Macrovipera lebetina lebetina (Linnaeus) that had been collected from northern Cyprus during laboratory work in the Zoology Section, Biology Department of the Ege University Faculty of Science. The clinical signs, physiological and biochemical changes soon after the venomous bi...

A new species of cat snake (Reptilia: Serpentes: Colubridae: Boiga) from dry forests of eastern Peninsular India.

A new species of cat snake, related to Boiga beddomei (Wall, 1909), is described from the dry forests of eastern Peninsular India. It occupies a large geographic range from Berhampore (type locality), near the River Mahanadi in the northeast to Kaigal near the southern Eastern Ghats in the southwest. The new species is diagnosed by having the following combination of characters: 19 dorsal scale...

Remyelination failure plays an important role in the pathophysiology of multiple sclerosis, but the underlying cellular and molecular mechanisms remain poorly understood. We now report actively demyelinating lesions in patients with multiple sclerosis are associated with increased glial expression of fibroblast growth factor 9 (FGF9), which we demonstrate inhibits myelination and remyelination ...
