Culture technology have permitted the generation of an artificial skin using human neonatal stem cells. A major advantage of this model is that epithelial-mesenchymal interactions are maintained. We have studied some morphological aspects concerning tissue organisation and cell differentiation using immunohistochemistry and electron microscopy. The epidermal equivalent was composed by a stratif...

Nanosilver and nanocurcumin are popular nonmaterial with increasing public attention, but their synergistic therapeutic potentials in burns have never been considered. The present study aimed to provide a novel formulation from both nanomaterials (Ag – Curcumin NPs) and conduct their preclinical evaluation for burn healing. After evaluation of particle size, loading efficiency, release profile ...

Background: This article reports on the current use of acellular dermal matrix in breast reconstruction. Methods: A literature review of articles on acellular dermal matrix in breast reconstruction from January 1, 2010, through December 20, 2016, was performed and analyzed for trends in acellular dermal matrix use and differences between commonly used acellular dermal matrixes. Findings: Clinic...

While neurogenic stem cells have been identified in rodent and human skin, their manipulation and further characterization are hampered by a lack of specific markers. Here, we perform genetic tracing of the progeny of boundary cap (BC) cells, a neural-crest-derived cell population localized at peripheral nerve entry/exit points. We show that BC derivatives migrate along peripheral nerves to rea...

The outcome of avian field studies was examined to model the likelihood of mortality. The data were divided into clusters reflecting the type of pesticide application and bird guilds present on site. Logistic regression was used to model the probability of a bird kill. Four independent variables were tested for their explanatory power: a variable reflecting acute oral toxicity and application r...

Collagen-Based Biomaterials Collagen-based biomaterials (CBBs) have been confirmed to prepare dressings and dermal substitutes, surgical sutures, plasma tissue-engineered scaffolds, etc. Article 2202042 by Xuechuan Wang, Huie Jiang, Xinhua Liu, co-workers, provides—in combination with the situation in China—thorough strides CBBs structures, cross-linking, forming technologies, real-world applic...

Dog is the main reservoir host of visceral leishmaniasis in Iran. The present study was carried out to investigate visceral leishmaniasis in owned dogs with dermal lesions in Mashhad, Khorasan Razavi province. Thirty- nine owned dogs with dermal lesions were selected. During study, four of dogs were euthanized. The dermal smears, blood and tissue samples were collected and examined using parasi...

This paper describes a new technique to inspect dermal ridges on the dermal surface instead of the epidermal surface. The dermal surface was exposed by chemical treatment and stained with toluidine blue. Dermal ridges are observable by the metachromatic effect of the reagent, which might suggest a close relationship between morphological characteristics and quantitative variations of biochemica...

Leishmania donovani in India causes visceral infection (kala-azar) and dermal infection (post-kala-azar dermal leishmaniasis). We report here the identification of polymorphism in a well-defined genetic locus among the Leishmania parasites causing the visceral and dermal manifestations, in a comparison of 15 post-kala-azar dermal leishmaniasis and 12 kala-azar patient isolates.
