Palaeomagnetic and synchrotron analysis of >1.95 Ma fossil-bearing palaeokarst at Haasgat, South Africa

South African Journal of Science, 2014
Palaeomagnetic analysis indicates that Haasgat, a fossil-bearing palaeocave in the Gauteng Province of South Africa, is dominated by reversed magnetic polarity in its oldest, deepest layers and normal polarity in the younger layers.

Hydrocarbon fluid inclusion fluorescence: A review

, 2021
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 ...

Interaction of high density lipoprotein particles with membranes containing cholesterol

Journal of Lipid Research, 2007
In this study, free cholesterol (FC) efflux mediated by human HDL was investigated using fluorescence methodologies. The accessibility of FC to HDL may depend on whether it is located in regions rich in unsaturated phospholipids or in domains containing ...

A versatile standard for bathochromic fluorescence based on intramolecular FRET. [PDF]

, 2011
A perylene and a terrylene tetracarboxylic bisimide dyad was prepared in which an efficient energy transfer from the former to the latter is observed. The absorption spectrum of this compound covers a broad range.

Biphasic Clinical Course of Pediatric Cytomegalovirus‐Associated Immune Thrombocytopenia: Early Poor Treatment Response but Favorable Long‐Term Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cytomegalovirus (CMV) is a recognized trigger of immune thrombocytopenia (ITP); however, its incidence and impact on disease course in children remain controversial. Therefore, we aimed to characterize the clinical course of pediatric patients with CMV‐associated ITP.

Detection and Quantification of DNA by Fluorophore-Induced Plasmonic Current: A Novel Sensing Approach

Sensors
We report on the detection and quantification of aqueous DNA by a fluorophore-induced plasmonic current (FIPC) sensing method. FIPC is a mechanism described by our group in the literature where a fluorophore in close proximity to a plasmonically active ...
