Introduction: Radiochemical purity (RCP) is a routine quality control test carried out at nuclear medicine to determine the concentration of various chemical species present in the radiopharmaceuticals (RPs). The present work describes three years of experience in a single institute for the measurement of these impurities in the RPs preparations. Methods: </strong...

The microleakage through margins of stainless steel crowns cemented with polycarboxylate, zinc phosphate, or glass ionomer cement was evaluated by measuring the amount of 4SCa leakage through the crown margins through 56 days after cementation in an in vitro environment. There was no cement-specific difference in marginal leakage as measured by this technique. The amount of leakage for each cem...

Background: Considerable thought has been given to the development of dressings and adhesives for use on chronic wounds. Dressings and adhesives used on acute (surgical/traumatic) wounds, however, have not had the same level of scrutiny regarding the skin damage that may be incurred on removal, particularly as the dressings are often removed after short application periods. Aims: To compare the...

BACKGROUND Bone staples are an accepted method of fixation in foot surgery. They reduce operating time and trauma in surgical procedures. A variety of memory staples are available but their properties compared to standard staples are not known. We carried out a study comparing two popular types of memory staples and a standard stainless steel staple. METHODS Standardized bone models of metata...

INTRODUCTION Varicocele is a common disease in adult men that can be treated with one of several surgical methods. Each technique has advantages and disadvantages, and conflicting results have been obtained by different studies. To evaluate the most effective surgical techniques used in adult bilateral varicocele, including minimally invasive procedures, we compared the outcomes of three common...

Biomarker is the measurable change associated with a physiological or pathophysiological process. Unlike blood which has mechanisms to keep the internal environment homeostatic, urine is more likely to reflect changes of the body. As a result, urine is likely to be a better biomarker source than blood. However, since the urinary proteome is affected by many factors, including diuretics, careful...
