Non-traditional Surgical Treatment of a Rolando Fracture.

Rolando fractures are comminuted, multifragmented, complete intra-articular fractures at the base of the thumb metacarpal. A review of the literature and our clinical practice shows that it can be treated in many ways. Patients with a non-displaced fracture require immobilization of the thumb.

Structural studies of calcium silicate hydrate modified with heavy metal cations.

This study investigates the immobilization mechanisms of heavy metal ions in the C-S-H phase. Synthetic C-S-H phases were prepared via the precipitation method, incorporating five different ions (Pb(II), Cd(II), Ni(II), Zn(II), and Cr(III)). Structural analysis of the obtained material was conducted using vibrational spectroscopy (both FT-IR and Raman), X-ray photoelectron spectroscopy, and X-ray diffraction.

Spectroscopic studies of heavy metal cations influence on the structure of synthetic hydrated calcium aluminosilicates.

Calcium aluminosilicate hydrates (C-(A)-S-H) with two different C/S molar ratios of 1.0 and 1.7 were synthesized by precipitation with the use of the alkali-activation method.

The use of orthoses in the treatment of carpal tunnel syndrome. A review of the literature from the last 10 years.

Introduction: A review of the literature from the last 10 years quite clearly shows that immobilization of the wrist in the splint (orthosis) is the most effective, initial method of conservative treatment of carpal tunnel syndrome (CTS). The particular advantages of the described method of treatment are: availability, low cost, good patient tolerance, simplicity and minimal incidence of complications.The aim of this study was to try to define the criteria of proceeding with the selection of the type of orthosis and the duration of its use depending on the clinical condition and the patient's expectations.

Carbon Fiber Reinforced Polymer Composites Doped with Graphene Oxide in Light of Spectroscopic Studies.

Carbon fiber reinforced polymer composites are a dynamically developing group of lightweight composites for applications in the automotive, wind energy, aerospace, and sports sectors. Interfacial connection is the weakest place in these materials. In this study, an attempt was made to improve adhesion between carbon fiber and epoxy resin.
