Long-term continuous atmospheric CO2 measurements at Baring Head, New Zealand [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
We present descriptions of the in situ instrumentation, calibration procedures, intercomparison efforts, and data filtering methods used in a 39-yr record of continuous atmospheric carbon dioxide (CO2) observations made at Baring Head, New Zealand ...

Bioconversion of vitamin D3 into calcitriol by Actinomyces hyovaginalis isolate CCASU- A11-2

open access: yesAMB Express, 2023
Vitamin D3 is a fat-soluble prohormone that is activated inside the liver to produce 25-hydroxyvitamin D3 (calcidiol), and in the kidney to produce the fully active 1α, 25-dihydroxy vitamin D3 (calcitriol).

A relaxed eddy accumulation flask sampling system for 14C-based partitioning of fossil and non-fossil CO2 fluxes [PDF]

open access: yesAtmospheric Measurement Techniques
A relaxed eddy accumulation (REA) system was developed and tested, enabling conditional sampling of air for subsequent 14CO2 analysis. This allows a 14C-based estimation of fossil fuel CO2 concentrations in the collected air samples and, thus, an ...

Scaling production of GFP1-10 detector protein in E. coli for secretion screening by split GFP assay

open access: yesMicrobial Cell Factories, 2021
Background The split GFP assay is a well-known technology for activity-independent screening of target proteins. A superfolder GFP is split into two non-fluorescent parts, GFP11 which is fused to the target protein and GFP1-10.

Protocol for generating reproducible miniaturized controlled midbrain organoids

open access: yesSTAR Protocols, 2023
Summary: Here, we present a protocol for generating miniaturized controlled midbrain organoids (MiCOs) of reproducible size and cellular composition, without a necrotic center. We describe steps for maintaining and passaging human pluripotent stem cells,

Fluid Dynamics Appearing during Simulated Microgravity Using Random Positioning Machines. [PDF]

open access: yesPLoS ONE, 2017
Random Positioning Machines (RPMs) are widely used as tools to simulate microgravity on ground. They consist of two gimbal mounted frames, which constantly rotate biological samples around two perpendicular axes and thus distribute the Earth's gravity ...
