Biochemical and functional characterization of glycosaminoglycans released from degranulating rat peritoneal mast cells: insights into the physiological role of endogenous heparin
(2016-12) - Journal articleThe properties of commercially prepared heparin as an anticoagulant and antithrombotic agent in medicine are better understood than is the physiological role of heparin in its native form, where it is uniquely found in the ... -
Biochemical and genetic analysis of the role of the viral polymerase in enterovirus recombination
(2016-08-19) - Journal articleGenetic recombination in single-strand, positive-sense RNA viruses is a poorly understand mechanism responsible for generating extensive genetic change and novel phenotypes. By moving a critical cis-acting replication ... -
Biochemical characterization of the initial steps of the Kennedy pathway in Trypanosoma brucei : the ethanolamine and choline kinases
(2008-10-01) - Journal articleEthanolamine and choline are major components of the trypanosome membrane phospholipids, in the form of GPEtn (glycero-phosphoethanolamine) and GPCho (glycerophosphocholine). Ethanolamine is also found as an integral ... -
Biodegradable hollow silica nanospheres containing gold nanoparticle arrays
(2015-06-21) - Journal articleWe introduce biodegradable hollow silica nanocapsules embedding arrays of 3 nm gold nanoparticles. The silica shell degrades in full serum in a few hours, potentially allowing the clearance of the capsules and their contents ... -
Biodiversity and ecosystem processes in heterogeneous environments
(University of St Andrews, 2008-06-27) - ThesisThe decline in biodiversity over the last decade has motivated researchers to investigate the relationship between species richness (biodiversity) and ecosystem function. Empirical approaches are becoming more realistic ... -
Biodiversity assessment of freshwater fishes : Thailand as a case study
(University of St Andrews, 2012-11-29) - ThesisA key challenge in biodiversity is: How many species are there on earth? This issue is especially acute in poorly surveyed regions with high diversity, particularly Southeast Asia that also experiences many limitations ... -
Biodiversity change in the Cerrado following invasive pine tree establishment
(University of St Andrews, 2017-12-07) - ThesisHow do newly established species interact with existing assemblage members to alter local biodiversity? This question is especially topical given growing concerns about increased temporal turnover levels relative to ... -
Biodiversity of freshwater fishes of Trinidad and Tobago, West Indies
(University of St Andrews, 1998) - ThesisThe proximity of the speciose South American continent to Trinidad and Tobago ensures that these islands have a rich and dynamic fauna. According to the equilibrium theory of island biogeography (MacArthur & Wilson ... -
Biogenesis pathways of RNA guides in archaeal and bacterial CRISPR-Cas adaptive immunity
(2015-05-20) - Journal itemCRISPR-Cas is an RNA-mediated adaptive immune system that defends bacteria and archaea against mobile genetic elements. Short mature CRISPR RNAs (crRNAs) are key elements in the interference step of the immune pathway. A ... -
Biogeochemical significance of pelagic ecosystem function : an end-Cretaceous case study
(2016-05) - Journal articlePelagic ecosystem function is integral to global biogeochemical cycling, and plays a major role in modulating atmospheric CO2 concentrations (pCO2). Uncertainty as to the effects of human activities on marine ecosystem ... -
Biogeography of the global ocean's mesopelagic zone
(2017-01-09) - Journal articleThe global ocean’s near-surface can be partitioned into distinct provinces on the basis of regional primary productivity and oceanography [1]. This ecological geography provides a valuable framework for understanding spatial ... -
A biogeography of the mesopelagic community
(University of St Andrews, 2016-11-30) - ThesisThere are a large number of research vessels and fishing vessels equipped with echosounders plying the world ocean, making continual observations of the ocean interior. Developing data collation programmes (e.g. Integrated ... -
A biographical and critical study of the life and writings of Sir David Dalrymple, Lord Hailes
(University of St Andrews, 1954) - ThesisThe name of Sir David Dalrymple, Lord Hailes has always been known to students of Scottish history by reason of his "Annals of Scotland", long accepted as a fundamental reference book for that period of Scottish history ... -
The biographical imagination in Moritz's Anton Reiser : a chronotopic reading
(2015-06) - Journal article -
The biological bases of conformity
(2012-06-14) - Journal articleHumans are characterized by an extreme dependence on culturally transmitted information and recent formal theory predicts that natural selection should favor adaptive learning strategies that facilitate effective copying ... -
Biological diversity of fish communities : pattern and process
(2011-12) - Journal articleFor over 150 years, ecologists have been striving to explain fundamental patterns of biological diversity, such as the observation that communities invariably consist of common and rare species, and to unravel the processes ... -
Biological diversity of freshwater fishes in small streams in peninsular Malaysia
(University of St Andrews, 2012) - ThesisPeninsular Malaysia has a diverse flora and fauna, much of which is yet to be documented. The freshwater fishes are one important group that have received little attention. Accordingly, the overarching goal of my study ... -
Biological overlap of attention-deficit/hyperactivity disorder and autism spectrum disorder : evidence from copy number variants
(2014-07) - Journal articleObjective: Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often co-occur and share genetic risks. The aim of this analysis was to determine more broadly whether ADHD and ASD share ... -
Biological regulation of atmospheric chemistry en route to planetary oxygenation
(2017-03-28) - Journal articleEmerging evidence suggests that atmospheric oxygen may have varied before rising irreversibly ∼2.4 billion years ago, during the Great Oxidation Event (GOE). Significantly, however, pre-GOE atmospheric aberrations toward ... -
The biological response of foraminifera to ocean acidification
(University of St Andrews, 2014) - ThesisElevated atmospheric concentrations of carbon dioxide (CO₂), partly driven by anthropogenic activity, are decreasing the pH of the oceans. This thesis aimed to assess the biological response of foraminifera to ocean ...
