Remodeling of collagen constituting interlobular septa of subcutaneous adipose tissue following microwaves application.

In this study, the application of a recently introduced device based on electromagnetic energy transfer by microwaves for fat reduction, permitted to study specifically the modifications of thick fibrous collagen interlobular septa in the subcutaneous adipose tissue, related to the formation of large clusters of adipocytes. The use of Picrosirius red staining associated with circularly polarized microscopy gave evidence of appreciable modifications of the fibrous connective tissue forming septa. Compact fibrotic bundles of collagen I forming interlobular septa appeared reduced or dissolved, in part substituted by the increase of more diffuse and finely reticular collagen III.

New System Delivering Microwaves Energy for Inducing Subcutaneous Fat Reduction: In - Vivo Histological and Ultrastructural Evidence.

Background: Recently, it has been developed a new technology for the reduction of subcutaneous adipose tissue through a non-invasive treatment by microwaves. The main objective of the present study is to demonstrate the feasibility of utilising a non-invasive, localised microwaves (MW) device to induce thermal modifications into subcutaneous adipose tissue only by a controlled electromagnetic field that heats up fat preferentially. This device is provided with a special handpiece appropriately cooled, directly contacting the cutaneous surface of the body, which provides a calibrated energy transfer by microwaves.

Early Regenerative Modifications of Human Postmenopausal Atrophic Vaginal Mucosa Following Fractional CO Laser Treatment.

Background: Postmenopausal women experience undesired symptoms that adversely affect their quality of life. In the recent years, a specific 12 - week fractional CO laser treatment has been introduced, with highly significant relief of symptoms.

Aim: The aim of this paper is the identification of the early modifications of structural components of atrophic vaginal mucosa induced by laser irradiation, which is responsible for the restorative processes.

In utero transplantation of adult bone marrow decreases perinatal lethality and rescues the bone phenotype in the knockin murine model for classical, dominant osteogenesis imperfecta.

Autosomal dominant osteogenesis imperfecta (OI) caused by glycine substitutions in type I collagen is a paradigmatic disorder for stem cell therapy. Bone marrow transplantation in OI children has produced a low engraftment rate, but surprisingly encouraging symptomatic improvements. In utero transplantation (IUT) may hold even more promise.

Effects of electromagnetic stimulation on calcified matrix production by SAOS-2 cells over a polyurethane porous scaffold.

There is increasing interest in designing new biomaterials that could potentially be used in the form of scaffolds as bone substitutes. In this study we used a hydrophobic crosslinked polyurethane in a typical tissue-engineering approach, that is, the seeding and in vitro culturing of cells using a porous scaffold. Using an electromagnetic bioreactor (magnetic field intensity, 2 mT; frequency, 75 Hz), we investigated the effect of the electromagnetic stimulation on SAOS-2 human osteoblast proliferation and calcified matrix production.

Microscopic, immunocytochemical, and ultrastructural properties of peri-implant mucosa in humans.

Background: Microscopic and immunocytochemical studies have demonstrated both similarities and differences between the gingival mucosa and the peri-implant mucosa restored around dental implants.

Methods: This study was performed on 10 samples of peri-implant mucosa from 10 patients who had undergone implant treatment 16 to 18 months before. Microscopic, ultrastructural, and immunocytochemical investigations were performed to characterize the epithelial and connective layers of the peri-implant mucosa.
