Addressing persistent challenges in digital image analysis of cancer tissue: resources developed from a hackathon

Molecular Oncology, EarlyView.
Large multidimensional digital images of cancer tissue are becoming prolific, but many challenges exist to automatically extract relevant information from them using computational tools. We describe publicly available resources that have been developed jointly by expert and non‐expert computational biologists working together during a virtual hackathon

The Application and Development of Electrochemical Hydride Generation in Atomic Spectrometry Analysis

Yankuang ceshi, 2014
Electrochemical hydride generation (EcHG) is an effective gas sampling method developed for atomic spectrometers. Electrode reactions are adopted in an electrochemical cell to generate hydride and mercury vapor in the cathode chamber for EcHG instead of ...

The C(3P) + NH3 reaction in interstellar chemistry: I. Investigation of the product formation channels [PDF]

, 2016
The product formation channels of ground state carbon atoms, C(3P), reacting with ammonia, NH3, have been investigated using two complementary experiments and electronic structure calculations. Reaction products are detected in a gas flow tube experiment (330 K, 4 Torr) using tunable VUV photoionization coupled with time of flight mass spectrometry ...

Intensity of atomic fluorescence as a function of atomic concentration in atomic fluorescence flame spectrometry

Spectrochimica Acta Part B: Atomic Spectroscopy, 1967
Abstract Expressions for the intensity of atomic fluorescence of atoms in atomic fluorescence flame spectrometry are derived by a simple approach. In this approach the atomic fluorescence of atoms at low and high concentrations excited by narrow line and continuous sources is considered, and the approach is general for resonance, stepwise-line, and ...

Adsorption Kinetics of Low Mercury Solution with Durian Shell and Activated Carbon

Yankuang ceshi, 2022
BACKGROUND The direct discharge of Hg(Ⅱ) is harmful to the environment. At present, activated carbon is used to remove it, but the production of activated carbon through high-temperature pyrolysis and activation is very expensive.

Respiratory complex I‐mediated NAD+ regeneration regulates cancer cell proliferation through the transcriptional and translational control of p21Cip1 expression by SIRT3 and SIRT7

Molecular Oncology, EarlyView.
NAD+ regeneration by mitochondrial complex I NADH dehydrogenase is important for cancer cell proliferation. Specifically, NAD+ is necessary for the activities of NAD+‐dependent deacetylases SIRT3 and SIRT7, which suppress the expression of p21Cip1 cyclin‐dependent kinase inhibitor, an antiproliferative molecule, at the translational and transcriptional
