The 5′ regulatory region of the human fetal globin genes is a gene conversion hotspot
(2008)The human fetal globin genes consist of the first mammalian genomic loci for which gene conversion was reported. To date, 14 gene conversions have been described in the human Gγ- and Aγ-globin genes, the vast majority of ... -
Agriculture and the threat to biodiversity in sub-saharan Africa
(2015)The Millennium Ecosystem Assessment identified habitat loss due to the extensive growth of agriculture as the primary driver of biodiversity loss. One implication of this is that agricultural intensification has the potential ... -
Effect of plasmin on movement characteristics of ejaculated bull spermatozoa
(2004)Proteolytic enzymes appear to have an essential role in multiple phases of mammalian fertilization. Several observations suggest that the plasminogen activator/plasmin system might also play a role in mammalian fertilization. ... -
Factors affecting biodiversity in agrosylvopastoral ecosystems with in the Mediterranean Basin: A systematic review
(2018)The biodiversity of Mediterranean agrosylvopastoral ecosystems has been extensively studied, because the Mediterranean Basin is a crossroad of biogeographical influences between cold temperate biota and subtropical species. ... -
Functional expression of mammalian opioid receptors in insect cells and high-throughput screening platforms for receptor ligand mimetics
(2005)Lepidopteran cell lines have been engineered to constitutively express high levels of mouse δ opioid receptors either alone or in combination with human Gα16 protein. Biochemical and pharmacological studies demonstrate ... -
Genes and conditions controlling mammalian pre-and post-implantation embryo development
(2015)Embryo quality during the in vitro developmental period is of great clinical importance. Experimental genetic studies during this period have demonstrated the association between specific gene expression profiles and the ... -
A gravity-based three-dimensional compass in the mouse brain
(2020)Gravity sensing provides a robust verticality signal for three-dimensional navigation. Head direction cells in the mammalian limbic system implement an allocentric neuronal compass. Here we show that head-direction cells ... -
Isolation and characterization of soil bacteria able to rapidly degrade the organophosphorus nematicide fosthiazate
(2019)Foshtiazate is an organophosphorus nematicide commonly used in protected crops and potato plantations. It is toxic to mammals, birds and honeybees, it is persistent in certain soils and can be transported to water resources. ... -
Microbial Degradation of Organophosphorus Xenobiotics: Metabolic Pathways and Molecular Basis
(2006)Organophosphorus (OP) xenobiotics are used worldwide as pesticides and petroleum additives. OP compounds share the major portion of the pesticide market globally. Owing to large-scale use of OP compounds, contaminations ... -
Phylogeography of roe deer (Capreolus capreolus) populations: The effects of historical genetic subdivisions and recent nonequilibrium dynamics
(2004)We sequenced 704 mitochondrial DNA (mtDNA) control-region nucleotides and genotyped 11 autosomal microsatellites (STR) in 617 European roe deer (Capreolus capreolus) samples, aiming to infer the species' phylogeographical ... -
Population genetics of cape and brown hares (Lepus capensis and L. europaeus): A test of Petter's hypothesis of conspecificity
(2008)Phylogenetic relationships and systematics of hares and jackrabbits (genus Lepus, Lagomorpha) are notoriously difficult. One intriguing issue is the relationship between cape hares (Lepus capensis L., 1758) and brown hares ... -
Sex-specific impact of inbreeding on pathogen load in the striped dolphin
(2020)The impact of inbreeding on fitness has been widely studied and provides consequential inference about adaptive potential and the impact on survival for reduced and fragmented natural populations. Correlations between ... -
A specific phospholipase C activity regulates phosphatidylinositol levels in lung surfactant of patients with acute respiratory distress syndrome
(2010)Lung surfactant (LS) is a lipid-rich material lining the inside of the lungs. It reduces surface tension at the liquid/air interface and thus, it confers protection of the alveoli from collapsing. The surfaceactive component ...
