Man-made mineral fibers and the respiratory tract.
Man-made mineral fibers are produced using inorganic materials and are widely used as thermal and acoustic insulation. These basically include continuous fiberglass filaments, glass wool (fiberglass insulation), stone wool, slag wool and refractory ceramic fibers. Likewise, in the last two decades nanoscale fibers have also been developed, among these being carbon nanotubes with their high elec...
متن کاملDurability of ceramic and novel man-made mineral fibers.
In vitro solubility testing is an important means of assessing the likely behavior of fibers that are respired and accumulate in the lung. The problem has been that such tests often do not mirror the dissolution and removal mechanisms seen in vivo. Comparison of iron and silica solubility values of various types of mineral fiber showed no obvious correlation. Treating a mineral fiber containing...

practice, the detection Ii mit of scanning electron microscopy is about 0.1 j.m (Middleton, 1982). Transmission electron microscopy may be required to detect very thin fibres (Rood & Streeter, 1985). The elemental composition of individual fibres can be determined with an energy-dispersive X-ray ana1ysis attachment combined with an electron microscope (Middleton, 1982). Fibres are counted and s...

متن کاملThe myofibroblast in wound healing and fibrosis: answered and unanswered questions
The discovery of the myofibroblast has allowed definition of the cell responsible for wound contraction and for the development of fibrotic changes. This review summarizes the main features of the myofibroblast and the mechanisms of myofibroblast generation. Myofibroblasts originate from a variety of cells according to the organ and the type of lesion. The mechanisms of myofibroblast contractio...
