ABSTRACT Non-invasive bioengineering technologies continuously discovered and developed in recent decades provide a significant input to research development and remarkably contribute to the improvement of medical education and care to our patients. AIM Assessing skin hydration by using the capacitance method for a group of patients with allergic contact dermatitis versus healthy subjects, be...

On the other hand, an increase in environmental humidity also induced abnormalities in permeability homeostasis [9] . In this issue of Exogenous Dermatology, environmental factors on dry skin are discussed by fi ve distinguished experts (or their groups) in this fi eld: Wertz (this issue) gives an integrated overview of the epidermal barrier function and their regional variations. His contribut...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...

Background and Aim: Although several commercial moisturizers are available in the market, continued role of pharmaceutical compounding have been still felt in dry skin management. This study aimed to evaluate the effect of a two urea- based compounded moisturizers on barrier function, compared to similar commercial product. 15 volunteers (14 females and one male) age 36.15 ±9.55 years old (rang...

Skin is the largest organ of the integumentary system with multiples important functions. Due to its complex structure, the permeability skin status can be modified by different external and internal factors such as chemical and physical stresses, and several skin and systemic diseases. Today, different non-invasive methods are used to assess the skin barrier biophysical properties. The paramet...

Friction and shear forces, as well as moisture between the human skin and textiles are critical factors in the formation of skin injuries such as blisters, abrasions and decubitus. This study investigated how epidermal hydration affects the friction between skin and textiles.The friction between the inner forearm and a hospital fabric was measured in the natural skin condition and in different ...

We present the design and use of an ultrathin, stretchable sensor system capable of conformal lamination onto the skin, for precision measurement and spatial mapping of levels of hydration. This device, which we refer to as a class of 'epidermal electronics' due to its 'skin-like' construction and mode of intimate integration with the body, contains miniaturized arrays of impedance-measurement ...

A novel method for in vitro calibration of skin hydration measurements is presented. The method combines gravimetric and electrical measurements and reveals an exponential dependency of measured electrical susceptance to absolute water content in the epidermal stratum corneum. The results also show that absorption of water into the stratum corneum exhibits three different phases with significan...
