Optical coherence tomography (OCT) is a non-invasive imaging technique, which has previously demonstrated potential for use in dermatology. The purpose of this study is to demonstrate how improvements in image quality, speed, and functionality enable qualitative and quantitative information to be obtained from in vivo human skin. We developed a portable fiber-optic based OCT imaging device that...

Three new species of Polycentropodidae (Insecta: Trichoptera) from the Northeast Region of Brazil are diagnosed, described, and illustrated. Polycentropus brevicornutus n. sp. of the Polycentropus gertschi Group can be diagnosed mainly by its much reduced, almost vestigial intermediate appendages, and by the inferior appendages, which are deltoid and very linear in lateral aspect. The two new s...

After surgical excision of hidradenitis suppurativa, reconstruction with a skin graft or a flap is performed when primary closure is not possible. However, the recurrence rate is reportedly high even after wide surgical excision. It is still unclear which reconstruction method provides the lowest recurrence rate. In this report, we present a case of intractable hidradenitis suppurativa in the b...

In female chickens of all breeds development of female feathering pattern is mediated by estrogens, whereas normal males and castrated chickens of both sexes develop male feathering. Male chickens carrying the henny feathering trait (such as the Sebright bantam and golden Campine) develop a female feathering pattern but otherwise virilize normally. To examine the possibility that the henny feat...
