Hyla versicolor, a tetraploid treefrog, is reported to have originated via multiple hybridization events involving three diploid ancestors. Its complex reticulate history provides insights into the roles that polyploidy and hybridization can play in the origin of species.

Background: Various industries produce and discharge wastes containing different heavy metals into the environment. Apart from using living biomass, dead and dried biomasses have been introduced as a new field of biotreatment technology. Method: The cadmium (Cd) (II) removal characteristics of live (growing), dead (autoclaved), and oven-dried biomasses of Aspergillus versicolor were examined a...

Tinea versicolor (TV) is a common cutaneous fungal infection characterized by superficial scaling and a mild disturbance of skin pigmentation. It typically affects the chest, upper back, and shoulders. However, involvement of more unusual regions of the body such as the face and scalp, arms and legs, intertriginous sites, genitalia, areolae, and palms and soles has been reported. This report de...

Frogs have two inner ear organs, each tuned to a different range of frequencies. Female treefrogs (Hylidae) of three species in which males produce calls with a bimodal spectrum (Hyla chrysoscelis, H. versicolor, H. arenicolor) preferred alternatives with a bimodal spectrum to alternatives with a single high-frequency peak. By contrast, females of H. avivoca, in which males produce calls with a...

There is little information on the indoor environment in hotels. Analysis of fungal DNA by quantitative PCR (qPCR) is a new method which can detect general and specific sequences. Dust was collected through swab sampling of door frames in 69 hotel rooms in 20 countries in Europe and Asia (2007-2009). Five sequences were detected by qPCR: total fungal DNA, Aspergillus and Penicillium DNA (Asp/Pe...

In a survey during a period of 2 years, 1084 patients with suspected clinical fungal lesions were referred to the Medical Mycology Department, School of Public Health of Tehran Medical Sciences University. Out of 1084 patients , 329 cases were found to be infested with Tinea versicolor. One (0.3%) conju­gal case and 2 (0.6%) blood related cases (Father and son, Mother and daugh­ter) and 4 cases...

CO2 emissions are the primary reason for global warming; hence, biological and chemical technologies converting into useful compounds being actively studied. Biological methods using enzymes can convert under mild conditions. Formate dehydrogenase (FDH) is a representative conversion enzyme. Its function was revealed after isolation from bacteria, yeast, plants. In this study, we evaluated pote...

Neobalanocarpus heimii (Cengal) is from the family Dipterocarpaceae. It a long-lasting wood that also one of most robust timbers in world. This species native to Peninsular Malaysia and southern Thailand. In this study, Cengal heartwood was studied concerning amount water extractive content with antifungal properties heimii. The dilution method used test properties. Wood meals samples were subj...
