Biophysical characterization and ion transport with cell‐based and proteoliposome reconstitution assays of invertebrate K+‐Cl− cotransporters

FEBS Open Bio, EarlyView.
The K+‐Cl− cotransporters (KCCs) facilitate the symport of ions across the plasma membrane. They participate in physiological processes including neuronal regulation. Here, we characterized KCCs from Drosophila and Hydra vulgaris. Comparative analyses of transporters provide insights into the mechanism of KCC ion transport, regulation, and evolution ...

Measurements of Bicarbonate in Water Containing Ocean-Level Sulfate Using a Simple Multi-Pass Optical Raman System

Oceans, 2021
The concentration of dissolved inorganic carbon in the oceans at depths of a few meters to thousands of meters is a critical parameter for understanding global warming. The concentration is both pH dependent and depth dependent.

Effect of Intraduodenal Bile and Taurodeoxycholate on Exocrine Pancreatic Secretion and on Plasma Levels of Vasoactive Intestinal Polypeptide and Somatostatin in Man [PDF]

, 1994
Intraduodenal (i.d.) application of bile or Na-taurodeoxycholate (TDC) dose dependently enhances basal exocrine pancreatic secretion. The hydrokinetic effect is mediated at least in part by secretin.

A recycling culture of Neochloris oleoabundans in a bicarbonate-based integrated carbon capture and algae production system with harvesting by auto-flocculation

Biotechnology for Biofuels, 2018
BackgroundA bicarbonate-based integrated carbon capture and algae production system (BICCAPS) uses carbonate to capture CO2 and produce bicarbonate for alkalihalophilic microalgal cultivation. In this process, carbonate is regenerated and re-used for CO2

Functional parameters of spermatozoa obtained by a new selection device

FEBS Open Bio, EarlyView.
This study compares density gradient centrifugation and the LensHooke CA0™ device for sperm separation. DGC requires multiple steps, specialized equipment, and technical expertise. In contrast, the CA0 device offers key practical and methodological advantages, resulting in a faster, simpler, and more affordable sperm selection method.

Effect of Intraduodenal Bile and Na-Taurodeoxycholate on Exocrine Pancreatic Secretion and on Plasma Levels of Secretin, Pancreatic Polypeptide, and Gastrin in Man [PDF]

, 1990
The effect of intraduodenally administered cattle bile (CB) and Na-taurodeoxycholate (TDC) on basal pancreatic secretion and plasma levels of secretin, pancreatic polypeptide (PP), and gastrin were investigated on two separate days in 10 fasting ...

In Situ Formation of a Melt‐Solid Interface Toward Stable Oxygen Reduction in Protonic Ceramic Fuel Cells

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...

Tetraethylammonium bicarbonate trihydrate [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
In the title compound, C(8)H(20)N(+)·CHO(3) (-)·3H(2)O, the bicarbon-ate anion, which has a small mean deviation from the plane of 0.0014 Å, fully utilises its three O and one H atom to form various O-H⋯O hydrogen bonds with the three water mol-ecules in the asymmetric unit, generating a hydrogen-bonded layer, which extends along (10[Formula: see text])
