abstract background: artificial hyperthermia in association with radiotherapy or chemotherapy has become a promising method for cancer treatment. thus, this study was designed to assess the impact of repetitive hyperthermia (41˚ ± 0.5˚c) on some normal histological, histochemical, and biochemical variables in newborn rats. materials and methods: after parturition, the neonates were randomly cho...

Due to their unique biochemical composition, sea cucumbers are highly prized marine echinoderm species. One of most important properties is that they contain a high amount collagen in body wall. In this study, the relationship between and pepsin-solubilized yields from Holothuria tubulosa poli morphometric parameters were investigated.
 Collagen range 10.63–16.04% for H. 7.12–13.10% poli. ...

ABSTRACT
 Background and Objective: Skin is a barrier that protects the body from outer environtment has cosmetic function. Aging biological process marked by deterioration of physiological function body. Collagen responsible in stability strength tissues. In recent years, oral collagen supplementation become popular because it’s distributed to peoples as an anti aging therapy. The aim thi...

Background: Extensive full-thickness burns require replacement of both epidermis and dermis. In designing skin replacements, the goal has been to re-create this model and make a product which has both essential components. Methods: In the present study, we developed procedures for establishing confluent, stratified layers of cultured human keratinocytes on the surface of modified collagen-chito...

Introduction: Skin resistance is greatly dependent on its collagen amount and nutritional substances such as crude protein that affect the skin collagen can indirectly influence the skin resistance and increase its strength. In this regard, this study aimed to evaluate the effect of in ovo methionine injection on histomorphometry of the skin layers. Methods: Thirty fertilized eg...
