Cranial dermis develops from cephalic mesoderm and neural crest cells, but what signal(s) specifies the dermal lineage is unclear. Using genetic tools to fate map and manipulate a cranial mesenchymal progenitor population in the supraorbital region, we show that the dermal progenitor cells beneath the surface ectoderm process canonical Wnt signaling at the time of specification. We show that Wn...

conclusions this method is recommended for the treatment of dermal warts, owing to the effectiveness, short duration of treatment, and low cost of topical treatment for dermal warts using hd tablets. background warts are common dermatological lesion caused by skin epithelial cells’ infection with human papillomavirus (hpv). objectives this study aimed to assess the efficacy of a new method for ...

Antibiotic resistance to microorganisms is one of the major problems faced in the field of wound care in burns patients. Silver nanoparticles have come up as potent antimicrobial agent and are being evaluated in diverse medical applications ranging from silver based dressings to silver coated medical devices. We aimed in present study to test the release of nanosilver from nanosilver wound dres...

Gamma-glutamyl carboxylase (GGCX) gene mutation causes GGCX syndrome (OMIM: 137167), which is characterized by pseudoxanthoma elasticum (PXE)-like symptoms and coagulation impairment. Here, we present a 55-year-old male with a novel homozygous deletion mutation, c.2,221delT, p.S741LfsX100, in the GGCX gene. Histopathological examination revealed calcium deposits in elastic fibers and vessel wal...

BACKGROUND Wound re-epithelialization has been traditionally described to occur from the dermal appendages of the wound edges. As such, the role of the dermal wound bed in re-epithelialization has been questioned. In a patient undergoing breast reconstruction with free tissue transfer, the buried portions of the free flap skin paddle could be either de-epithelialized or deskinned. In case of ma...

The regulatory risk assessment of chemicals requires the estimation of occupational dermal exposure. Until recently, the models used were either based on limited data or were specific to a particular class of chemical or application. The EU project RISKOFDERM has gathered a considerable number of new measurements of dermal exposure together with detailed contextual information. This article des...

Mutations in the caspase recruitment domain, family member 14 (CARD14) gene have recently been described in psoriasis patients, and explain the psoriasis susceptibility locus 2 (PSORS2). CARD14 is a scaffolding protein that regulates NF-κB activation, and psoriasis-associated CARD14 mutations lead to enhanced NF-κB signaling. CARD14 is expressed mainly in epidermal keratinocytes, but also in un...

BACKGROUND To minimize the inflammatory reaction and improve healing, a new modified dermal substitute composed of an atelocollagen, chondroitin-6-sulfate, and amniotic membrane (AM) was applied to full-thickness skin defects in a pig. Atelocollagen was extracted from bovine skin, and two modified dermal substitutes were generated according to the cross-linking type. METHODS The AM-collagen d...
