Patterns Of Calcium Oxalate Crystal Production By Three Species Of Wood Decay Fungi, Jon H. Connolly, Howard J. Arnott, Jody Jellison
Patterns Of Calcium Oxalate Crystal Production By Three Species Of Wood Decay Fungi, Jon H. Connolly, Howard J. Arnott, Jody Jellison
Scanning Microscopy
Wood decay experiments using red spruce wood resting on moist soil were conducted to discern temporal and spatial patterns of calcium oxalate (CaOx) crystal production by three species of fungi over the course of decay. All three species produced crystals of calcium oxalate dihydrate, but not monohydrate, in and on wood. Over the course of decay, the production of CaOx crystals was shown to be heterogeneous in both space and time. The relative quantity, morphology and longevity of CaOx crystals varied among species. Gloeophyllum (G.) trabeum produced substantial quantities of "free" crystals; Fomitopsis (F.) pinicola produced encrusting crystals; and Trichaptum …
Effects Of Ionizing Radiation On Cartilage: Emphasis On Effects On The Extracellular Matrix, M. Cornelissen, H. Thierens, L. De Ridder
Effects Of Ionizing Radiation On Cartilage: Emphasis On Effects On The Extracellular Matrix, M. Cornelissen, H. Thierens, L. De Ridder
Scanning Microscopy
In this report, we review data dealing with radiation effects on cartilage. More specifically, we emphasize on alterations caused in the extra-cellular cartilage matrix. Although radiation studies predominantly describe the effect on the structure of DNA and on the mitotic activity of cells, alterations caused by the effect on the non-mitotic activity can also be important. Cartilage, having an extracellular matrix composed of 2 major components, aggrecan and collagen, provides a good model to study this kind of radiation effects. The following topics concerning literature data are summarized: effects on the amount of matrix synthesized, effects on the activity of …
