Essential oils from plants used in traditional medicine are known as a rich source of chemically diverse compounds with specific biological activities. Achillea millefolium essential oil (AEO) was screened for vitro activity against Babesia canis. The AEO obtained by hydrodistillation and analysed gas chromatography coupled to mass spectrometry (GC-MS). GC-MS revealed the presence 47 oil. Those...

Rhamnus virgatus Roxb. (Syn. R. dahuricus Pall.), Rhamnaceae, is a deciduous shrub, 1.8}4.5 m in height, found throughout the Himalayas at an altitude of 800}3000 m. Aerial parts (twigs with leaves) of R. virgatus were collected in July 1996, from Musoli, Pauri District, Garhwal, UP, India and identi"ed by Dr. L.R. Dangwal, Department of Botany, HNB Garhwal University Srinagar (Garhwal), India....

A comprehensive understanding of coral reproduction and development is needed because corals are threatened in many ways by human activity. Major threats include the loss of their photosynthetic symbionts (Symbiodinium) caused by rising temperatures (bleaching), reduced ability to calcify caused by ocean acidification, increased storm severity associated with global climate change and an increa...

Through the examination of past and present distributions of plants and animals, historical biogeographers have provided many insights on the dynamics of the massive organismal exchange between North and South America. However, relatively few phylogeographic studies have been attempted in the land bridge of Mesoamerica despite its importance to better understand the evolutionary forces influenc...

Objective: The present in vitro studies aimed to investigate the pancreatic and extrapancreatic effects of crude aqueous extracts (AE) of Achillea santolina L, Eryngium creticum Lam, and Pistacia atlantica Desf utilized in Jordan diabetes ethnomedicine. Methods: Bioassays of β-cell proliferation and insulin secretion as well as glucose diffusion as possible modes of action were recruited. Resul...
