Re‐Os Dating of Sulfides from the Volcanogenic Massive Sulfide Deposit at Gacun, Southwestern China [PDF]
Resource Geology, 2003 Abstract. The Re‐Os isotopic compositions of sulfide ores were analyzed for the Gacun, a volcanogenic massive sulfide deposit in southwestern China, to constrain the timing of mineralization. Sulfide ores from the deposit have a wide range of Re and Os concentrations, varying from 80.2 to 1543.2 ppb and from 0.307 to 8.83 ppb, respectively, and ...

Luminescence Dating of Medieval and Early Modern Brickwork [PDF]
, 2009 Essex is a county rich in significant historic brickwork spanning the medieval period. A great deal of earlier archaeological study has focused on the development and use of brick during this period, providing a framework of understanding as to how this

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Application of the 190Pt-186Os isotope decay system to dating platinum-group minerals [PDF]
, 2010 Constraining the formation age of platinum-group minerals (PGM) in placer deposits has traditionally been very challenging. The 190Pt-186Os decay system, measured by laser ablation multi-collector ICPMS (LA-MC-ICPMS), has been demonstrated as a useful ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Role of Terrestrial Organic Matter in Re and Os Uptake: Insights for Re-Os Dating of Organic-Bearing Sedimentary Rocks and Weathering of Organic Carbon [PDF]
The rhenium-osmium (Re-Os) isotope system is a powerful tool for dating organic-rich sedimentary rocks, yet the mechanisms of Re and Os uptake and their fractionation in different types of organic matter remain poorly understood. Here, we investigate the
