Comparative Analysis of Structural Responses of Rat Subcutaneous Fat on the Implantation of Samples of Polymethyl Methacrylate with Hydrophobic and Hydrophilic Surface.

Morphological analysis of the subcutaneous fat was performed in rats after subcutaneous implantation of basic dental plastic materials with different hydrophobic and hydrophilic properties. It was shown that subcutaneous implantation of dental plastics with mostly hydrophobic surface and low biocompatibility induced destructive and inflammatory processes of various intensities, sometimes with allergic component; morphological signs of processes persisted for 6 weeks. Modification of basic plastics using glow-discharge plasma and enhancement of their hydrophilicity and biocompatibility significantly reduced the intensity of destructive and inflammatory processes and ensured more rapid (in 2 weeks) repair of the destroyed tissues with the formation of fibrous capsule around the implant.

Comparative in vivo assessment of some adverse bioeffects of equidimensional gold and silver nanoparticles and the attenuation of nanosilver's effects with a complex of innocuous bioprotectors.

Stable suspensions of nanogold (NG) and nanosilver (NS) with mean particle diameter 50 and 49 nm, respectively, were prepared by laser ablation of metals in water. To assess rat's pulmonary phagocytosis response to a single intratracheal instillation of these suspensions, we used optical, transmission electron, and semi-contact atomic force microscopy. NG and NS were also repeatedly injected intraperitoneally into rats at a dose of 10 mg/kg (0.

Increasing the general level of academic capacity in general practice: introducing mandatory research training for general practitioner trainees through a participatory research process.

Background: To obtain good quality evidence-based clinical work there needs to be a culture of critical appraisal, and strong bridges between the clinical and the academic worlds in general practice.

Aim: The aim was to educate the general practitioner (GP) trainees to obtain critical appraisal skills, and through the development and implementation of the mandatory programme to gradually empower the GP community to achieve academic capacity by creating a link between the GP researchers and the GP training community. This was done by developing a faculty, giving teaching skills to GP academics, and research skills to GP clinicians; and creating an awareness of the potential benefits of critical appraisal in training GP surgeries.

[Developing training in critical appraisal for GP trainees in the Eastern Region of Denmark].

In 2004 training in critical appraisal became a mandatory part of the Danish medical specialist training. In this article we describe how the course was designed and implemented on the basis of experience from previous research training initiatives targeting GPs and GP-trainees; and how we continuously develop the course and tailor the training of teachers for the course using a multi-method participatory evaluation design, theoretically based on Stenhouse's definition of the curriculum as a process and the teachers as researchers.

Structural reactions of the buccal mucosa in diabetic parodontopathy.

Pronounced changes in the capillaries, hemodynamic disorders, epitheliocyte degeneration and atrophy develop in the buccal mucosa of patients with types I and II diabetes mellitus in the absence of inflammatory cellular infiltration or with facultative infiltration. The morphogenesis of pathological changes can be regarded as primary diabetic microangiopathy causing metabolic disorders with the development of degenerative and atrophic changes in all structural components of the buccal mucosa and development of diabetic parodontopathy, a primary degenerative process.
