The actin cytoskeleton and adhesion junctions are physically and functionally coupled at the cell-cell interface between epithelial cells. The actin regulatory complex Arp2/3 has an established role in the turnover of junctional actin; however, the role of formins, the largest group of actin regulators, is less clear.

Abstract Gap junctions are essential to the function of multicellular animals, which require a high degree of coordination between cells. In vertebrates, gap junctions comprise connexins and currently 21 connexins are known in humans.

abstract A concern about modular stems is that the taper will not provide an adequate seal, causing the stem distal to the taper to become part of the effective joint space. In this study, 380 primary patients and 309 revision patients were treated with a proximally modular stem. Follow-up was between 5 and 17 years (mean 9.4 years).

ABSTRACT Tight junctions are the most apical intercellular junctions of epithelial and endothelial cells and create a regulatable semipermeable diffusion barrier between individual cells. On a cellular level, they form an intramembrane diffusion fence that restricts the intermixing of apical and basolateral membrane components.

Perception, 1997
The lightness of a test patch completely surrounded by an inducing field can be predicted by variants of Wallach's ratio rule. When a patch is surrounded by two or more regions with different luminances, a plausible extension of the ratio rule would predict that the effect of the surrounding regions should correlate with the length of the border they ...

Neurosurgery Clinics of North America, 2007
The cervicothoracic junction (CTJ) represents a unique region in the spine because of its biomechanical properties. It is predisposed to various traumatic injuries, tumor, and iatrogenic instability. It is also a difficult region to access anteriorly because of the vital structures ventral to the CTJ.

ABSTRACT Gap junctions are intercellular structures that link cells and allow them to exchange ions and small metabolites without recourse to the extracellular space (for reviews and early references, see Goodenough, 1979; Loewen-stein, 1981).

Proximal Junctional Kyphosis and Proximal Junctional Failure
Neurosurgery Clinics of North America, 2013Proximal junctional failure (PJF) should be distinguished from proximal junctional kyphosis, which is a recurrent deformity with limited clinical impact. PJF includes mechanical failure, and is a significant complication following adult spinal deformity surgery with potential for neurologic injury and increased need for surgical revision.

Summary Currently available diagnostic techniques involving manometric studies, pH determinations, and cineradiographic techniques have added considerably to our knowledge of the normal and abnormal function of the esophagogastric junction. Nevertheless, these must be viewed in perspective, and they cannot supplant sound clinical judgment in the ...

Tight Junctions and Gap Junctions
2010Tight junctions have several major functions. They seal the intercellular space in epithelial and endothelial cell layers and prevent free paracellular passage of substances. They determine the polarity of epithelial cells by creating a boundary between the apical domain of the plasma membrane and the basolateral domain and prevent diffusion of lipids ...
