BACKGROUND Onychomycosis is the most common nail disease and represents around 50% of nail disorders. Accurate diagnosis with adequate evidence is ideal before starting any treatment. Current diagnostic methods offer low specificity and sensitivity. AIMS To create a new method for the diagnosis of onychomycosis, and to compare its sensitivity and specificity with the existing methods. METHO...

in this work, old newspaper fibers (onf) bleached with h2o2, treated with koh and treated with naocl were investigated as potential adsorbents. the characterization of the produced fibers using ft-ir, sem and particle size distribution have been carried out and tested for the removal of ni (ii) from aqueous solutions. the results indicated that the fibers treated with koh give the highest %remo...

Staining with calcofluor white (CFW), which is known to bind chitin-rich areas of the cell wall, revealed a difference in the fluorescence intensity at the hyphal tip between Candida albicans hyphal cells that were grown in modified Lee (M-Lee) and SPG media. The fluorescence intensity at the tip increased with the addition of salts and sugar to SPG. The chitin levels per dry cell weight in cel...

The trimethylamine content of most marine fish, especially the gadoid species, is internationally accepted as an index ofspoilage. However, ammonia, dimethylamine, and other aminesalso contribute to the trimethylamine value. Variations in the conditions of the three current methods used to analyze for trimethylamine content were studied in detail to determine the best condition to extract trime...
