This paper deals with the refractoriness of PET \ mouse integument to the subcutaneous administration of nerve growth factor. Newborn mice were injected once daily with NGF through ten injections. Gross and histological examination showed that the skin of the experimental animals was completely unresponsive to this agent. No alterations in the hair growth cycle or pattern were ·observed.

Members of the YABBY family of putative transcription factors participate in abaxial-adaxial identity determination in lateral organs in Arabidopsis (Arabidopsis thaliana). Two YABBY genes specifically expressed in reproductive structures, CRABS CLAW (CRC) and INNER NO OUTER (INO), have additional activities, with CRC promoting nectary development and carpel fusion, and INO responding to spatia...

The fifth instar larva of the saturniid silkworm, Rhodinia fugax, is light yellowish-green on its dorsal surface and dark green on the ventral surface with a lateral demarcation between the two colours. The larva of R. fugax closely resembles the leaves of the host plant, Quercus serrata, in colour and shape. The spectral reflectance of the larval integument of R. fugax corresponds to that of t...

Hygrobates specimens with a coarse lineated soft integument generally have been considered as representatives of H. calliger Piersig, 1896, regarded common and widely distributed species in the Palaearctic. In present study using an integrative taxonomic approach that combines morphological studies DNA barcoding we show calliger-like mites belong to six distinct lineages. Two species, ponticus ...
