Electron capture decay of indium-111 human carbonic anhydrase I: A time differential K X ray coincidence perturbed angular correlation study [PDF]

arXiv, 2003
The relaxation effects in the perturbed angular correlation spectra of indium-111 human carbonic anhydrase I (HCA I) are the result of chemical transmutation and/or the complex Auger cascades that follow the electron capture decay of indium-111. Time differential K X ray coincidence perturbed angular correlation (PAC) spectroscopy shows that these ...

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

Advanced Energy Materials, EarlyView.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

Novel benzofuran-based sulphonamides as selective carbonic anhydrases IX and XII inhibitors: synthesis and in vitro biological evaluation

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Pursuing on our efforts toward searching for efficient hCA IX and hCA XII inhibitors, herein we report the design and synthesis of new sets of benzofuran-based sulphonamides (4a,b, 5a,b, 9a–c, and 10a–d), featuring the zinc anchoring benzenesulfonamide ...

Benefit from Biomass Boiler Emissions to Increase Greenhouse CO2 Levels for Optimal Growth and Yield in Tomato, Cucumber, and Strawberry

Advanced Energy and Sustainability Research, EarlyView.
Using CO2‐rich polluting gases in greenhouse plant cultivation has proven to be a promising technique for stimulating plants while reducing emissions to the atmosphere. The use of an experimental biofilter proves to be effective in retaining most of the toxic particles. The alteration of physiological and metabolic parameters shows an adaptation of the

Metabolic Effect of Estrogen Receptor Agonists on Breast Cancer Cells in the Presence or Absence of Carbonic Anhydrase Inhibitors

Metabolites, 2016
Metabolic shift is one of the major hallmarks of cancer development. Estrogen receptor (ER) activity has a profound effect on breast cancer cell growth through a number of metabolic changes driven by its effect on transcription of several enzymes ...

Valorizing the carbon byproduct of methane pyrolysis in batteries [PDF]

arXiv, 2022
While low-cost natural gas remains abundant, the energy content of this fuel can be utilized without greenhouse gas emissions through the production of molecular hydrogen and solid carbon via methane pyrolysis. In the absence of a carbon tax, methane pyrolysis is not economically competitive with current hydrogen production methods unless the carbon ...

Classifying Hypoxia in Breast Cancer Xenografts Using a Single‐Cell Mass Spectrometry Imaging Model

Analysis &Sensing, EarlyView.
Hypoxia is a common feature in solid tumors and is linked to aggressiveness and therapy resistance. This study uses single‐cell mass spectrometry imaging of cultured cells exposed to different oxygen levels to spatially classify hypoxia in breast cancer xenografts.

Carbonic anhydrase activity investigation in the present of Sodium oxalate and Ethylendiamine [PDF]

بیولوژی کاربردی, 2018
Introduction: Carbonic anhydrases are ubiquitous zinc containing metalloenzymes which catalyze the interconversion of bicarbonate and CO2. This enzyme is involved in various vital physiological processes related to respiration, renal acidification, pH ...

Beta-carbonic anhydrases play a role in fruiting body development and ascospore germination in the filamentous fungus Sordaria macrospora.

PLoS ONE, 2009
Carbon dioxide (CO(2)) is among the most important gases for all organisms. Its reversible interconversion to bicarbonate (HCO(3) (-)) reaches equilibrium spontaneously, but slowly, and can be accelerated by a ubiquitous group of enzymes called carbonic ...
