Electrically layered tissue structure significantly modifies distribution of radiofrequency (RF) current in the dermis and in the subcutaneous adipose tissue comparing to that in a homogeneous medium. On the basis of the simple model of RF current distribution in a two-layer skin containing dermis and subcutis, we assess the influence of the dermal thickness on the current density in different ...

Background: Bacterial diseases in cultured fish are considered the main problem to aquaculture system. Skin is the structure that covers the body in fish. Skin histopatological alterations were used to assess the effects of Aeromonas hydrophila exposure on the yellowfin seabream )Acanthopagrus latus(. Methods: In this regard, 90 A. latus were exposed to sublethal concentrations of A. hydrophil...

Background: Human fibroblasts are the part of the dermis that secrete extracellular matrix for the purpose of tissue repair. Culturing fibroblasts, which leads to formation of a monolayer of these cells, is used for treating various conditions including thermal burns and other skin defects such as diabetic and varicose vein leg ulcers. Therefore, we aimed at developing a fibroblast bank to acco...

OBJECTIVE Skin creases are features of major anatomical, morphological, surgical, and functional interest. This study focuses on the histological comparison of creases of the trunk and participation of the elastic fibers in their formation. The histological structure is a key consideration for the reconstructive planning of the relevant area and its knowledge may contribute in such direction. ...

BACKGROUND Reactive oxygen species (ROS) contribute to processes relating to cutaneous aging. Iron catalyses ROS formation whereas ascorbic acid (AA) plays a fundamental role in defending the organism against undesirable ROS action. OBJECTIVE The aim of this work was to determine the ex vivo iron and AA concentrations in human dermis from different age groups to better understand their role. ...

The accurate histopathological evaluation, the diagnosis, and the assessment of level of invasion of malignant melanoma have assumed a role of paramount importance in defining need for further surgery, a chemotherapeutic or immunotherapeutic approach to management, and prognosis. The classification of melanoma into lentigo maligna melanoma, superficial spreading melanoma, and nodular melanoma a...
