High-precision U-Pb ages in the early Tithonian to early Berriasian and implications for the numerical age of the Jurassic-Cretaceous boundary [PDF]

, 2019
The numerical age of the Jurassic-Cretaceous boundary has been controversial and difficult to determine. In this study, we present high-precision U-Pb geochronological data around the Jurassic-Cretaceous boundary in two distinct sections from different ...

Molybdenite Re-Os Isotopic Dating of Xitian Deposit in Hunan Province and Its Geological Significance

Yankuang ceshi, 2014
The Xitian large-scale W-Sn polymetallic ore field has been explored in recent years. It is found in jointed adjoining areas of the Nanling and Qinhang metallogenic belts which are located on the boundary between Hunan and Jiangxi provinces, and the junction of the Yangtze and Cathaysia blocks.

Metabologenomic Hallmark‐Based Discovery of Bacterial Thioamides as a New Lead against Drug‐Resistant Pancreatic Cancer

Advanced Science, EarlyView.
A targeted metabologenomic strategy integrating genomic and metabolomic hallmarks enabled the discovery of two new thioamides, thiogochangamides A and B, from bacteria. Their absolute configurations, previously unresolved within the thioviridamide family, were fully assigned through various chemical derivatizations and computational analysis ...

Abrupt climate changes of the last deglaciation detected in a Western Mediterranean forest record [PDF]

, 2009
Abrupt changes in Western Mediterranean climate during the last deglaciation (20 to 6 cal ka BP) are detected in marine core MD95-2043 (Alboran Sea) through the investigation of high-resolution pollen data and pollen-based climate reconstructions by the ...

Quantitative Mass Spectrometry‐Based Biodistribution of Monoclonal Antibodies: An Alternative to Radio‐Biodistribution

Advanced Science, EarlyView.
Monoclonal antibodies are powerful anticancer therapeutics targeting tumor‐associated antigens. Mass spectrometry enables precise and accurate quantification of mAbs in tumor plasma and healthy organs. Unlike ligand binding assay and radioactivity, mass spectrometry does not suffer from matrix effects and labelling artefacts while facilitating method ...

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery

Advanced Science, EarlyView.
We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent
