Hepatology, EarlyView., 2022 CHIN117 is a dual cysteinyl leukotriene receptor 1 (CYSLTR1) antagonist and G‐protein‐coupled bile acid receptor 1 (GPBAR1) agonist. In the liver, GPBAR1 and CYSLTR1 are coexpressed by liver sinusoidal endothelial cells (LSECs), HSCs, circulating monocytes/macrophages, and liver resident macrophages (Kupffer cells).

Reduced Background Expression and Improved Plasmid Stability with pET Vectors in BL21 (DE3)
BioTechniques, 2000 The T7 polymerase-based pET System™ is one of the most powerful and widely used prokaryotic expression systems available today. Expression of even slightly toxic gene products in BL21 (DE3), however, has been problematic due to basal expression, which ...

Long-Term Potentiation Is Increased in the CA1 Area of the Hippocampus of APPswe/ind CRND8 Mice
Neurobiology of Disease, 2002 The present study reports changes in synaptic function and plasticity [long-term potentiation (LTP)] in a recently developed mouse model of Alzheimer's disease (CRND8 line) harboring a double amyloid precursor protein mutation (APPswe/ind). In 9-week-old

Variation of tow force with velocity during offshore ploughing in granular materials [PDF]
, 2012 Pipeline plough behaviour has been investigated by means of reduced scale physical model testing. A testing programme was devised to investigate the influence of permeability, relative density, and plough depth on the associated tow force measured during

The influence of incorporating a forecutter on the performance of offshore pipeline ploughs [PDF]
, 2013 Installation of offshore pipelines in the seabed can be efficiently achieved using pipeline ploughs. Increased efficiency may be achievable through incorporating a smaller forecutter in advance of the main plough share.

Abyssal plain faunal carbon flows remain depressed 26 years after a simulated deep-sea mining disturbance [PDF]
Biogeosciences, 2018 Future deep-sea mining for polymetallic nodules in abyssal plains will negatively impact the benthic ecosystem, but it is largely unclear whether this ecosystem will be able to recover from mining disturbance and if so, to what extent and at what ...
