The Role of Osteocytes in Targeted Bone Remodeling: A Mathematical Model [PDF]

, 2013
Until recently many studies of bone remodeling at the cellular level have focused on the behavior of mature osteoblasts and osteoclasts, and their respective precursor cells, with the role of osteocytes and bone lining cells left largely unexplored. This

The characteristics of collagen‐induced rheumatoid arthritis in macaques and the changes of heart

Animal Models and Experimental Medicine, EarlyView.
The disease progression in CIA macaques was categorized into three stages: IIR (days 14–34): The indicators related to rheumatoid arthritis and the levels of immunoglobulin were all elevated. There was a small amount of joint effusion, edema and mild synovial hyperplasia. No joint swelling was observed by naked eye.

Osteoprotegerin levels in ST-elevation myocardial infarction: Temporal profile and association with myocardial injury and left ventricular function. [PDF]

PLoS ONE, 2017
BACKGROUND:Elevated levels of osteoprotegerin (OPG) have been associated with adverse outcomes in ST-elevation myocardial infarction (STEMI). However, the role of OPG in myocardial injury and adverse remodeling in STEMI patients remains unclear. The aims

Maximizing Maximal Angles for Plane Straight-Line Graphs [PDF]

, 2007
Let $G=(S, E)$ be a plane straight-line graph on a finite point set $S\subset\R^2$ in general position. The incident angles of a vertex $p \in S$ of $G$ are the angles between any two edges of $G$ that appear consecutively in the circular order of the ...

Ontogeny of murine bony semicircular canal form

The Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

RANKL/OPG ratio regulates odontoclastogenesis in damaged dental pulp

Scientific Reports, 2021
Bone-resorbing osteoclasts are regulated by the relative ratio of the differentiation factor, receptor activator NF-kappa B ligand (RANKL) and its decoy receptor, osteoprotegerin (OPG).

Estrogen activation of microglia underlies the sexually dimorphic differences in Nf1 optic glioma-induced retinal pathology [PDF]

, 2016
Children with neurofibromatosis type 1 (NF1) develop low-grade brain tumors throughout the optic pathway. Nearly 50% of children with optic pathway gliomas (OPGs) experience visual impairment, and few regain their vision after chemotherapy.
