Microthermometry and Raman spectroscopy of fluid inclusions from El Vapor gold mineralizations, Colombia

open access: yesEarth Sciences Research Journal, 2018
Epigenetic El Vapor gold mineralization is hosted by the Segovia batholith and sedimentary rocks at both sides of El Nús fault, in the eastern flank of the Colombian Andes central cordillera.

The Influence of Hydrothermal Activity on the Long-Distance Migration and Accumulation of Hydrocarbons: A Case Study from the Y8 Area in the Songnan-Baodao Sag of Qiongdongnan Basin

open access: yesEnergies, 2022
The Qiongdongnan (QDN) basin in the northwestern South China Sea has been shown to be rich in petroleum resources and has significant exploration potential for deepwater oil and gas resources.

Threshold size for fluid inclusion decrepitation [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2015
AbstractFluid inclusions in igneous and metamorphic rocks are equilibrated at pressures reaching a few tens of kilobars at mantle depths. These microsystems experience decompression as a consequence of uplift processes, such as subaerial volcanic eruptions. On decompression, inclusion fluid overpressure is known to bring about the mechanical failure of

Ablation of LRP6 in alpha‐smooth muscle actin‐expressing cells abrogates lung inflammation and fibrosis upon bleomycin‐induced lung injury

open access: yesFEBS Letters, EarlyView.
Low‐density lipoprotein receptor‐related protein 6 (LRP6) is a key receptor for the Wnt antagonist Dickkopf1 (DKK1). DKK1 protein expression is induced in a bleomycin (BLM)‐induced lung injury model. We show that DKK1 induces proinflammatory and profibrotic genes in lung fibroblasts.

Talc-bearing Metadolomites of the Itaiacoca Group, Paraná (Southern Brazil): Fluid Regime and Genetic Implications [PDF]

open access: yesGeologia USP. Série Científica, 2011
Brazil’s largest talc deposits occur in the Itaiacoca Group, which is a low-grade metasedimentary belt composedmainly of dolomitic rocks. Fluid inclusions from three geological settings in which talc was formed differently wereanalysed.

The internal states of active inclusions and the dynamics of an active membrane [PDF]

open access: yes, 2003
A theoretical model of a two-component fluid membrane containing lipids and two-state active inclusions is presented. Under strong inclusion activities the membrane can be unstable due to pump-driven undulation or aggregation of high curvature excited inclusions.

Hydrocarbon Fluid Inclusion Fluorescence: A Review

open access: yes, 2009
Geological fluid inclusions are small voids that can contain a variety of liquids which are often found in natural minerals and rocks. Typically they are less than 10 micrometres in size that host fossil fluids which existed when the minerals grew or healed after fracture.

Making tau amyloid models in vitro: a crucial and underestimated challenge

open access: yesFEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Micro-crystalline inclusions analysis by PIXE and RBS [PDF]

open access: yesNuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms 266, 10 (2008) 2375-2378, 2008
A characteristic feature of the nuclear microprobe using a 3 MeV proton beam is the long range of particles (around 70 \mu m in light matrices). The PIXE method, with EDS analysis and using the multilayer approach for treating the X-ray spectrum allows the chemistry of an intra-crystalline inclusion to be measured, provided the inclusion roof and ...

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

open access: yesFEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...
