Study on mechanical properties and microscopic damage mechanism of tight sandstone reservoir under uniaxial compression

open access: yesFrontiers in Energy Research, 2023
Due to the characteristics of low porosity, low permeability and serious anisotropy in tight reservoirs, it is difficult for conventional hydraulic fracturing theory to accurately guide the efficient exploitation of tight reservoirs.

Mechanisms of Biliary Damage

open access: yesJournal of Cell Death, 2010
Bile duct damage is present in virtually all cholangiopathies, which share the biliary epithelial cells (i.e. cholangiocytes) as a common pathogenic target. Cholangiocyte cell death largely occurs through the process of apoptosis. In this review, we will summarize the mechanisms through which biliary damage occurs in a variety of animal and in vitro ...

Mechanisms of ischemic brain damage [PDF]

open access: yesNeuropharmacology, 2008
In the United States stroke is the third leading cause of death and the leading cause of disability. Brain injury following stroke results from the complex interplay of multiple pathways including excitotoxicity, acidotoxicity, ionic imbalance, peri-infarct depolarization, oxidative and nitrative stress, inflammation and apoptosis.
