A spherical-plot solution to linking acceleration metrics with animal performance, state, behaviour and lifestyle
( BioMed Central , 2016 , Article)Background We are increasingly using recording devices with multiple sensors operating at high frequencies to produce large volumes of data which are problematic to interpret. A particularly challenging example comes from ... -
Anti-atherosclerotic plants which modulate the phenotype of vascular smooth muscle cells
( Elsevier , 2016 , Article)Background: Cardiovascular disease (CVD) remains the leading cause of global death, with atherosclerosis being a major contributor to this mortality. Several mechanisms are implicated in the pathogenesis of this disease. ... -
The biogeochemical iron cycle and astrobiology
( Springer International Publishing , 2016 , Article)Biogeochemistry investigates chemical cycles which influence or are influenced by biological activity. Astrobiology studies the origin, evolution and distribution of life in the universe. The biogeochemical Fe cycle has ... -
Soil moisture effects on leaf litter decomposition and soil carbon dioxide efflux in wetland and upland forests
( Soil Science Society of America , 2014 , Article)This study examined, first, the response of litter decomposition and soil CO2 efflux (RS) to different soil moisture conditions and, second, the application of various litter decomposition functions in a wetland and upland ... -
Foraging in space and time structure an African small mammal community
( Springer Verlag , 2014 , Article)We used live-trapping and foraging to test for the effect of habitat selection and diet on structuring a community of six small mammals and one bird within the Soutpansberg, South Africa. We established grids that straddled ... -
Concentrations and dynamics of fungal spore populations in the air of Zarqa, Jordan, using the volumetric method
( Taylor & Francis , 2014 , Article)This study was initiated to investigate seasonal and intradiurnal variations in concentrations of airborne fungal spores of the Zarqa area in Jordan based on daily spore trapping. A total of 76 396 fungal spores belonging ... -
First report of Thielaviopsis punctulata causing black scorch disease on date palm in Qatar
( American Phytopathological Society , 2014 , Article)Ceratocystis radicicola (anamorph: Thielaviopsis paradoxa) was reported as an economically important pathogen causing serious diseases on date palm such as rhizosis (2) and black scorch (3) or as an associated pathogen ... -
Impact of phytolacca Americana extracts on gene expression of colon cancer cells
( John Wiley & Sons, Ltd , 2014 , Article)Native Americans have used Phytolacca americana to treat breast ailments, gastrointestinal disorders, rashes, and inflammation. Some anti-cancer and anti-viral research has been reported on this perennial herb, but none ... -
Impacts of CO2-induced seawater acidification on coastal Mediterranean bivalves and interactions with other climatic stressors
( Springer Berlin Heidelberg , 2014 , Article)The effects of seawater acidification caused by increasing concentrations of atmospheric carbon dioxide (CO2), combined with other climatic stressors, were studied on 3 coastal Mediterranean bivalve species: the mussel ... -
Mechanisms underlying the antihypertensive effects of garlic bioactives
( Elsevier Inc. , 2014 , Article)Cardiovascular disease remains the leading cause of death worldwide with hypertension being a major contributing factor to cardiovascular disease–associated mortality. On a population level, non-pharmacological approaches, ... -
Connecting the dots between PubMed abstracts
( Public Library of Science , 2012 , Article)Background: There are now a multitude of articles published in a diversity of journals providing information about genes, proteins, pathways, and diseases. Each article investigates subsets of a biological process, but to ... -
An estimation of erinaceidae phylogeny: A combined analysis approach
( Public Library of Science , 2012 , Article)Background: Erinaceidae is a family of small mammals that include the spiny hedgehogs (Erinaceinae) and the silky-furred moonrats and gymnures (Galericinae). These animals are widely distributed across Eurasia and Africa, ... -

Mitochondrial phylogeography illuminates the origin of the extinct caspian tiger and its relationship to the amur tiger
( Public Library of Science , 2009 , Article)The Caspian tiger (Panthera tigris virgata) flourished in Central Asian riverine forest systems in a range disjunct from that of other tigers, but was driven to extinction in 1970 prior to a modern molecular evaluation. ... -
Anti-Metastatic and Anti-Tumor Growth Effects of Origanum majorana on Highly Metastatic Human Breast Cancer Cells: Inhibition of NFκB Signaling and Reduction of Nitric Oxide Production
( Public Library of Science , 2013 , Article)Background: We have recently reported that Origanum majorana exhibits anticancer activity by promoting cell cycle arrest and apoptosis of the metastatic MDA-MB-231 breast cancer cell line. Here, we extended our study by ... -
Examining the Extinction of the Barbary Lion and Its Implications for Felid Conservation
( Public Library of Science , 2013 , Article)Estimations of species extinction dates are rarely definitive, yet declarations of extinction or extirpation are important as they define when conservation efforts may cease. Erroneous declarations of extinctions not only ... -
