Tyrosine phosphorylation profiling in FGF-2 stimulated human embryonic stem cells. [PDF]

PLoS ONE, 2011
The role of fibroblast growth factor-2 (FGF-2) in maintaining undifferentiated human embryonic stem cells (hESC) was investigated using a targeted phosphoproteomics approach to specifically profile tyrosine phosphorylation events following FGF-2 ...

Serum bile acids as a prognostic biomarker in biliary atresia following Kasai portoenterostomy

Hepatology, EarlyView., 2022
Serum bile acid levels predict outcomes in patients with biliary atresia who achieve normalized bilirubin levels after Kasai portoenterostomy. Abstract Background and Aims In biliary atresia, serum bilirubin is commonly used to predict outcomes after Kasai portoenterostomy (KP).

Chelator‐Free Radiometal Labeling Inside Engineered Affibodies

Angewandte Chemie, EarlyView.
Affibodies are compact and robust three‑helix binders used in imaging and therapy. Engineering a triple‑cysteine motif into their core enables chelator‑free binding of important radiometals, like Bi(III), Pb(II), In(III), and Ga(III) with rapid uptake and exceptional stability.

Method for estimating the inventory of an isotope separation cascade by the use of minor isotope transient concentration data [PDF]

, 1978
An indirect method for estimating the inventory of a uranium enrichment cascade which presumably can be performed by the International Atomic Energy Agency within the Non-Proliferation Treaty limitations on its safeguards activities was devised and tested at the Oak Ridge Gaseous Diffusion Plant (ORGDP).

The lacustrine-water vapor isotope inventory experiment L-WAIVE [PDF]

, 2020
Abstract. In order to gain understanding on the vertical structure of atmospheric water vapour above mountain lakes and to assess the respective influence of evaporation and advection processes, the L-WAIVE (Lacustrine-Water vApor Isotope inVentory Experiment) field campaign was conducted in the Annecy valley in the French Alps in June 2019.

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Cyclo‐Polyproline: Chameleonic All‐Peptide Macrocycles With Induced‐Fit Host‐Guest Recognition

Angewandte Chemie, EarlyView.
Macrocycles served as the genesis of supramolecular chemistry, advancing synthetic, separation, and materials fields. Despite their utility, they typically lack synthetic control. This work establishes a robust platform for all‐peptide macrocycles capable of host‐guest complexation and chameleonic behavior.

Assessment of the regional fossil fuel CO2 distribution through Δ14C patterns in ipê leaves: The case of Rio de Janeiro state, Brazil

City and Environment Interactions, 2019
Fossil fuel-derived CO2 (Cff) emission patterns and their point sources across the Rio de Janeiro megacity and state were estimated from a single regional-scale Δ14C distribution map based on isotopic measurements of ipê leaves (Tabebuia, a popular ...

Heme‐NO Dilates Arteries via Mobilization of NO Moieties From an Intracellular NO Store Within Vascular Smooth Muscle Cells

Advanced Science, EarlyView.
Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...

Methane emissions in Kuwait: Plume identification, isotopic characterisation and inventory verification

Atmospheric Environment, 2022
Abstract The distribution of methane sources in Kuwait was mapped through mobile vehicle surveying of methane mole fraction, and by collection of air samples at source for subsequent isotopic analysis. Mobile plume identification and isotopic analysis, reveals that by far the largest observed source of methane in Kuwait is from landfill sites ...
