Deformation-Induced Mechanical Instabilities at the Core-Mantle Boundary [PDF]

, 2007
Post-Perovskite: The Last Mantle Phase Transition Our understanding of the core-mantle boundary (CMB) region has improved significantly over the past several years due, in part, to the discovery of the post-perovskite phase.

Optimised Fermentation Production of Radiolabelled Ochratoxin A by Aspergillus ochraceus with Maximum ¹⁴C in the Pentaketide Moiety for Exploring Its Rat Renal Toxicology

Toxins, 2023
In the context of the mysterious Balkan endemic nephropathy of the 1900s, and the discovery in the 1960s of the potent mycotoxin ochratoxin A, experimental research projects sought to explore any inter-relationship.

Recycling of continental crust materials: Geochemical constraints from post-collisional alkaline intrusive rocks in the Dabie orogen

Frontiers in Earth Science, 2023
Post-collisional alkaline intrusive rocks from the Dabie orogen were studied for their whole-rock major-trace elements and Sr-Nd-Hf-Pb isotopes, as well as zircon U-Pb ages and Hf-O isotopes.

Mantle Plumes and Mantle Sources [PDF]

Science, 1992
Basalts from many ocean islands define elongate arrays in Sr-Nd-Pb isotopic space; these likely reflect the dominance of binary mixing of mantle sources in intraplate volcanism. S. R. Hart et al. (1) observe that when these arrays are projected onto a ternary diagram bounded by mantle end-members DMM [depleted mid-ocean ridge basalt (MORB) mantle ...

Comparative Ergot Alkaloid Elaboration by Selected Plectenchymatic Mycelia of Claviceps purpurea through Sequential Cycles of Axenic Culture and Plant Parasitism

Biology, 2020
Ergot alkaloids have an established place in plant pathology and toxicology. As pharmaceuticals, their sourcing is via natural or managed agricultural occurrence of sclerotia of Claviceps purpurea (Fr.) Tul.

From Continent to Ocean: Investigating the Multi-Element and Precious Metal Geochemistry of the Paraná-Etendeka Large Igneous Province Using Machine Learning Tools

Earth Science, Systems and Society, 2021
Large Igneous Provinces, and by extension the mantle plumes that generate them, are frequently associated with platinum-group element (PGE) ore deposits, yet the processes controlling the metal budget in plume-derived magmas remains debated.

Transcriptome and digital gene expression analysis reveal immune responses of mantle and visceral mass pearl culturing in Hyriopsis cumingii

Frontiers in Marine Science, 2023
Biomineralization is a widespread phenomenon in marine mollusks and is responsible for the production of shells and pearls. However, the regulatory mechanisms governing the adaptive immune responses in the mollusk mantle and visceral mass during ...

Slipper Limpet (Crepidula fornicata) Shells Support In Vitro Osteogenesis of Human Adipose-Derived Stem Cells

Marine Drugs, 2023
This study aimed to investigate a cost-effective alternative to man-made calcium phosphate ceramics for treating bone defects. The slipper limpet is an invasive species in European coastal waters, and its shells composed of calcium carbonate could ...

Geomagnetic Impulses and the Electrical Conductivity of the Lower Mantle [PDF]

, 1991
This thesis is an investigation of the changes in the magnetic field as measured at the surface of the Earth on the time-scale of months to decades. In particular the phenomena of geomagnetic "impulses" or "jerks" are investigated.

Nasal Decolonisation of MRSA

Antibiotics, 2019
The recent demonstration for the first time of urinary monic acid A as a clinical urinary biomarker of exposure to intra-nasal mupirocin during medication for methicillin-resistant Staphylococcus aureus (MRSA) offers a way of verifying adherence to the ...
