The objective of this study is to establish a relationship of the skin penetration parameters between the three-dimensional cultured human epidermis LabCyte EPI-MODEL (LabCyte) and hairless mouse (HLM) skin penetration in vitro and to predict the skin penetration and plasma concentration profile in human. The skin penetration experiments through LabCyte and HLM skin were investigated using 19 d...
Estimation of permeation of compounds such as chemical warfare agents (CWAs) alone or through barrier creams such as SERPACWA (Skin Exposure Reduction Paste Against Chemical Warfare Agents) requires animal experiments or in vitro testing using animal or human skin. While animal skin does not reflect the same barrier properties as human skin, human skin poses problems of procurement, cost and la...
CONTEXT AND OBJECTIVE The technique of obtaining human skin with dermis and epidermis reconstructed from cells isolated from patients can enable autologous skin grafting on patients with few donor sites. It also enables in vitro trials on chemicals and drugs. The objective of this work was to demonstrate a method for obtaining human skin composed of associated dermis and epidermis, reconstructe...
Background and purpose: Health quality of fish as an important source of protein for human has received increasing attention. This study, examined the concentrations of chromium, nickel, zinc, and copper in the muscle and skin tissues of two edible fish species of Alosa Caspica and Clupeonella cultiventris caspia in the southern Caspian Sea in 2013. Also, the risk assessment of consumption of t...
The insertion and expression of genes in the epidermis may have a variety of therapeutic uses, including the treatment of skin diseases. Here we show that when both human skin organ cultures and human skin grafts on immunocompromised mice are injected with naked DNA, the DNA is taken-up and genes are expressed in the epidermis in a manner similar to both pig skin injected in vivo and injected p...
Introduction: Egyptian cockroach is one of the species of cockroaches, which has a worldwide distribution, and can live in closed human environments. In this paper, we present the first reported patient with skin reactions and dermatitis to Egyptian cockroach in Iran. Case Report: An 80-year-old man referred to the clinic with skin lesions on his right foot. The patient lived in an adobe hou...
One of the most important functions of the skin is to protect against various stressors. Environmental stimuli such as UV and environmental pollution increase reactive oxygen species and cause wrinkles and skin aging. Skin aging is associated with decreased collagen production and decreased activity of enzymes involved in collagen structure. Moisturizing chemicals increase the skin's ability to...
background: skin cancer can be treated by various methods. electron radiotherapy has been a useful therapeutic modality in the treatment of skin cancers in areas which are difficult to cure by other methods. depth dose distribution of 166ho using varskin2 code is presented in this work. material and methods: depth dose distribution of 166ho was calculated, using varskin2 code by adding of 166ho...
