Resistant superficial dermatophytic infections of the skin and its appendages have emerged as a major health problem in India. Mutations Squalene epoxidase gene led to increasing incidence resistance terbinafine isolates. We examined six patients with recalcitrant dermatophytosis attending Dermatology OPD at tertiary care hospital demonstrated by molecular method. Immediate hyperitivity (IH) re...

Integuments form the boundary between an organism and the environment. The evolution of novel developmental mechanisms in integuments and appendages allows animals to live in diverse ecological environments. Here we focus on amniotes. The major achievement for reptile skin is an adaptation to the land with the formation of a successful barrier. The stratum corneum enables this barrier to preven...

The evolution of amniotes has involved major molecular innovations in the epidermis. In particular, distinct structural proteins that undergo covalent cross-linking during cornification of keratinocytes facilitate the formation of mechanically resilient superficial cell layers and help to limit water loss to the environment. Special modes of cornification generate amniote-specific skin appendag...

Star-nosed moles have a series of mechanosensory appendages surrounding each nostril. Each appendage is covered with sensory organs (Eimer's organs) containing both rapidly adapting and slowly adapting mechanoreceptors and each appendage is represented in primary somatosensory cortex (S1) by a single cortical module. When the skin surface of an appendage is depressed, neurons in the correspondi...

Vitiligo is a dermatological disease; its exact prevalence is unknown among the paediatric population. We are reporting a case of vitiligo at birth for the first time in Burkina Faso, in the Teaching Hospital Souro Sanou of Bobo-Dioulasso, Paediatric Department. He is a male child, born from HIV-1 positive parents; we received him when he was 2 months to be followed in connection with the preve...

Feathers are appendages of skin in avians and provide a model for analyzing skin appendage morphogenesis. The feathers of Chinese Silky (CS) and White Leghorn (WL) chickens have distinct phenotypes. Based on preliminary genetic results, we cloned the chicken gene sobp (encoding sine oculis binding protein homolog, which is expressed at a higher level in the dorsal skin and in the feather follic...

Background and aim: The skin has some appendages that give origin to various tumors. These tumors are generally divided to pilosebaceous and sweat glands tumors according to embryologic and histological features. Clinical and histological characteristics of these tumors are also divergent. In addition, classification of them according to histological background has been changed considerably in ...

A Large scale of full-thickness skin defects is lack of auto-grafts and which requires the engineered skin substitutes for repair and regeneration. One major obstacle in skin tissue engineering is to expand epidermal stem cells (ESCs) and develop functional substitutes. The other one is the scaffold of the ESCs. Here, we applied type I collagen-modified chitin membrane to form collagen-chitin b...
