Giant velvet mites, the largest living are a familiar sight when they present above ground, usually after first summer rains, in warm arid areas. Despite their often-conspicuous presence enormous numbers, little is known about basic biology, life history strategies, or predators. The emergence of Dinothrombium magnificum (LeConte, 1852) southern Arizona, USA occurs rain that exceeds 1 cm. Of 17...

Integument from blue and green areas of the variant blue frog were analyzed biochemically for pteridines and carotenoids. Solvent extraction and absorption spectrophotometry indicated that p carotene was greatly reduced in the blue skin, and present in high quantities in the green skin of the blue frog. Thin layer and paper chromatography indicated that the pteridines were almost totally lackin...

We present here a classical case of Sturge Weber Disease. This 16 month male child had facial angioma and seizures. CT Scan head was consistent with the diagnosis.

Calliphorin, Insect Cuticle, Immunofluorescence, Calliphora vicina Injections of radioactively labelled calliphorin into Illrd instar larvae of Calliphora indicate that the protein is incorporated into the integument. Immunofluorescence techniques show that the endocuticle is the Final site of deposition of calliphorin. It is concluded that calliphorin is an essen­ tial protein of the tanned cu...
