BACKGROUND Pytiriasis versicolor is an infectious disease caused by several Malassezia species which has a tendency to become relapsing or chronic. OBJECTIVES This study was conducted in an attempt to investigate the clinical course of pityriasis versicolor with regard to the number of relapses after a 12-month therapy and correlate this number with isolates of Malassezia species. MATERIAL ...

The laccase enzyme is the largest group of Oxidoreductase enzymes and is capable of oxidizing a wide range of organic substrates to water along with molecular oxygen resuscitation. ZnO nanoparticles are known for their specific properties such as chemical stability, high electrochemical coupling rates, and wide range of absorption of radiation as multifunctional compounds. In this study, ZnO po...

There is considerable evidence supporting a role for mold exposure in the pathogenesis and expression of childhood asthma. Aspergillus versicolor and Cladosporium cladosporioides are common molds that have been implicated in asthma. In a model of mold-induced asthma, mice were repeatedly exposed to either A. versicolor or C. cladosporioides spores. The two molds induced distinct phenotypes, and...

We investigated the ability of Trametes versicolor and Pycnoporous cinnabarinus to metabolize triclosan. T. versicolor produced three metabolites, 2-O-(2,4,4'-trichlorodiphenyl ether)-beta-D-xylopyranoside, 2-O-(2,4,4'-trichlorodiphenyl ether)-beta-D-glucopyranoside, and 2,4-dichlorophenol. P. cinnabarinus converted triclosan to 2,4, 4'-trichloro-2'-methoxydiphenyl ether and the glucoside conju...

Pityriasis versicolor is a common superficial fungal infection of the skin which is caused by various species of yeast of the genus Malassezia and is clinically characterized by scaly hypo pigmented or hyper pigmented macules usually involving the upper trunk, upper arms, neck and abdomen [1]. Lesions of pityriasis versicolor confined to face has rarely been reported. In this article the author...

We show that a twistor space of a self-dual metric on 4CP with U(1)-isometry is not Moishezon iff there is a C∗-orbit biholomorphic to a smooth elliptic curve, where the C∗-action is the complexification of the U(1)action on the twistor space. It follows that the U(1)-isometry has a two-sphere whose isotropy group is Z2. We also prove the existence of such twistor spaces in a strong form to sho...

Epidermodysplasia verruciformis is an inherited disorder, characterized by multiple plane warts, pityriasis versicolor-like lesions, defects of cell-mediated immunity, and tendency to develop skin malignancies, primarily on sun-exposed areas. In this article, we present a case of epidermodysplasia verruciformis with multiple plane warts, pityriasis versicolor-like lesions, and squamous cell car...

Isometric twitch and tetanus parameters, force-velocity curves, maximum shortening velocity (Vmax) and percentage relaxation between stimuli (%R) across a range of stimulus frequencies were determined for a muscle used during call production (the tensor chordarum) and a locomotor muscle (the sartorius) for three species of hylid frogs, Hyla chrysoscelis, H. versicolor and H. cinerea. The call o...

The mushroom Flammulina velutipes and the white-rot fungus Trametes versicolor were cultivated separately on sugarcane bagasse for 40 days. Trametes versicolor produced laccase and manganese-peroxidase activities, showing a simultaneous degradation of lignin and holocellulose. However, only phenoloxidase activity was found with Flammulina velutipes. A preferential degradation of lignin was dete...
