PHOTODEGRADATION OF PHAEOMELANIN: AN IN VITRO MODEL

Photochemistry and Photobiology, 1980
Abstract— A new in vitro model system for studying the photochemistry and photobiology of melanins in epidermal tissue has been developed. The photochemistry of phaeomelanin in this model system follows the same course as in pH 8.0 aqueous buffered solutions, i.e. photodegradation accompanied by production of superoxide radicals.

An in vitro model of caloric restriction

Experimental Gerontology, 2003
The mechanisms underlying the ability of caloric restriction (CR) to extend life span and enhance stress responsiveness remain elusive. Progress in this area has been slow due to the complexities of using animals for CR studies and assessing life span as the measure of CR effectiveness. It is therefore of great interest to develop in vitro models of CR.

Development of an in vitro bladder model

Nursing Standard, 1992
The first of the three articles in this series (1) expounded the case for a broader approach to research design in nursing. In particular, the experimental approach and the use of laboratory studies were highlighted as areas that nurses have tended to neglect.

In vitro models for human neuroglia

Neuroglia are a heterogenous population of cells in the nervous system. In the central nervous system, this group is classified into astrocytes, oligodendrocytes, and microglia. Neuroglia in the peripheral nervous system are divided into Schwann cells and enteric glia. These groups of cells display considerable differences in their developmental origin,

An In Vitro Model of Ischemic Stroke

2011
Brain stroke is a devastating cerebrovascular disease and ranks as the third most common cause of death and disability in the US. Altered blood-brain barrier (BBB) signaling and permeability characteristics during stroke can increase the risk for life-threatening hemorrhagic transformation or damaging brain edema.

In Vitro Model of Cartilage Degradation

2010
This 14-day model of cartilage breakdown involves stimulation of bovine nasal cartilage with a combination of interleukin-1 and oncostatin M. Media is harvested on days 7 and 14 and the conditioned media and remaining cartilage at day 14 assayed for the levels of proteoglycan and collagen fragments using biochemical assays.

In Vitro Viable Skin Model

1996
Until recently, in vitro percutaneous absorption studies were conducted with non-viable skin. Early studies have shown that for many chemicals good in vivo-in vitro agreement can be obtained with nonviable skin (Bronaugh et al., 1982a). This is most likely due to the fact that the nonliving upper layer of skin, the stratum corneum, is a major barrier ...
