Cell Morphology, Viability, Osteocalcin Activity, and Alkaline Phosphatase Activity in Milled versus Unmilled Surface of the Femoral Head

Journal of Orthopaedic Surgery, 2016
Purpose To evaluate cellular activity in milled versus unmilled surface of the femoral head in 21 patients who underwent robot-assisted total hip arthroplasty (THA). Methods The femoral head of 21 consecutive patients who underwent robot-assisted THA for

Three distinct mechanisms generate oxygen free radicals in neurons and contribute to cell death during anoxia and reoxygenation [PDF]

, 2007
Ischemia is a major cause of brain damage, and patient management is complicated by the paradoxical injury that results from reoxygenation. We have now explored the generation of reactive oxygen species (ROS) in hippocampal and cortical neurons in ...

Granzymes in health and diseases: the good, the bad and the ugly

Frontiers in Immunology
Granzymes are a family of serine proteases, composed of five human members: GA, B, H, M and K. They were first discovered in the 1980s within cytotoxic granules released during NK cell- and T cell-mediated killing.

Ethylene augments root hypoxia tolerance through amelioration of reactive oxygen species and growth cessation [PDF]

, 2022
Flooded plants experience impaired gas diffusion underwater, leading to oxygen deprivation (hypoxia). The volatile plant hormone ethylene is rapidly trapped in submerged plant cells and is instrumental for enhanced hypoxia acclimation.

In the eye of the storm: T cell behavior in the inflammatory microenvironment. [PDF]

, 2013
Coordinated unfolding of innate and adaptive immunity is key to the development of protective immune responses. This functional integration occurs within the inflamed tissue, a microenvironment enriched with factors released by innate and subsequently ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Assessing Bioenergetic Function in Response to Reactive Oxygen Species in Neural Cells

, 2020
In this study, we characterized the bioenergetic response of the Lund human mesencephalic (LUHMES) cell line and a mouse astrocyte cell line to oxidative stress. Extracellular hydrogen peroxide (H2O2) levels and bioenergetic response were investigated in
