Stable Isotope Compositions of Wild and Farmed S. Paramoamosion and its Implication for Tracebility

Journal of Isotopes, 2014
To evaluate the possibility of using stable isotopes for discriminating wild and farmed mangrove crabs, Stable carbon and nitrogen isotope ratios of Scylla paramamosion tissues were analyzed. The carbon and nitrogen isotope ratios of wild S. paramamosion

A ¹⁵N stable isotope semen label to detect mating in the malaria mosquito Anopheles arabiensis Patton [PDF]

, 2008
In previous studies it was determined that the stable isotope 13-carbon can be used as a semen label to detect mating events in the malaria mosquito Anopheles arabiensis. In this paper we describe the use of an additional stable isotope, 15-nitrogen (15N)

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Research Progress on Black Carbon Isotope Analytical Pre-treatments

Journal of Isotopes
As a product of incomplete combustion of biomass and fossil fuels，black carbon has an important impact on many fields such as climate change，health，environment and carbon cycle. For a long time，δ13C and Δ14C analysis have been widely used in black carbon

Life history traits of the fish community in Lake Annecy: evidence from the stable isotope composition of otoliths

Knowledge and Management of Aquatic Ecosystems, 2015
Stable isotope analysis (SIA) of fish otoliths shows great potential for exploring the ecology of fish, but this method has not been applied to the study of lacustrine fish communities.

Using stable isotopes of nitrogen and carbon to study seabird ecology: applications in the Mediterranean seabird community

Scientia Marina, 2003
The application of the stable isotope technique to ecological studies is becoming increasingly widespread. In the case of seabirds, stable isotopes of nitrogen and carbon have been mainly used as dietary tracers. This approach relieson the fact that food

UDP‐Glucose‐6‐Dehydrogenase Mediated O‐GlcNAcylation of Tight Junction Protein 1 Suppresses Metastasis in Renal Cell Carcinoma

Advanced Science, EarlyView.
Our research unveiled a regulatory paradigm wherein TRIM25 orchestrates the ubiquitin‐mediated degradation of UGDH. UGDH modulates the protein stability of TJP1 by regulating O‐GlcNAcylation levels, effectively impeding the metastasis of ccRCC. Our insights elevate UGDH to a pivotal biomarker and tumor suppressor, marking the first demonstration that ...

Factors influencing the stable carbon isotopic composition of suspended and sinking organic matter in the coastal Antarctic sea ice environment [PDF]

, 2011
A high resolution time-series analysis of stable carbon isotopic signatures in particulate organic carbon (δ13CPOC) and associated biogeochemical parameters in sea ice and surface waters provides an insight into the factors affecting δ13CPOC in the ...

Synergy of Pd Clusters and TiO2 {101} for Photocatalytic Nonoxidative Coupling of Methane

Advanced Science, EarlyView.
This study presents photocatalytic nonoxidative coupling of methane over cal‐Pd0.05/TiO2{101}, achieving near 100% selectivity and long‐term stability under mild flow conditions through synergistic single atoms and clusters catalysis. ABSTRACT Photocatalytic nonoxidative coupling of methane (NOCM) offers a sustainable route to valorize CH4 into C2 ...

Seasonally varying contributions to urban CO2 in the Chicago, Illinois, USA region: Insights from a high-resolution CO2 concentration and δ13C record

Elementa: Science of the Anthropocene, 2015
Understanding urban carbon cycling is essential given that cities sustain 54% of the global population and contribute 70% of anthropogenic CO2 emissions. When combined with CO2 concentration measurements ([CO2]), stable carbon isotope analyses (δ13C) can
