The authors review the main concepts regarding the importance of cleaning/disinfection of ultrasonography probes, aiming a better comprehension by practitioners and thus enabling strategies to establish a safe practice without compromising the quality of the examination and the operator productivity. In the context of biosafety, it is imperative to assume that contact with blood or body fluids ...

The recently developed fundamental measure density functional theory (Hansen-Goos and Mecke 2009 Phys. Rev. Lett. 102 018302) for an inhomogeneous anisotropic hard body fluid is used as a basic ingredient in treating the Brownian dynamics of hard spherocylinders. After discussing the relevance of a free parameter in the fundamental measure density functional for the isotropic-nematic transition...

OBJECTIVE To determine the prevalence of occupational exposure (OE) occurring to dentists, dental nurses and senior dental students in a Chinese dental hospital and to assess associated factors with these exposures. METHODS Data were collected through anonymous questionnaires, which were distributed to dentists, nurses, and senior dental students. RESULTS All 205 dental personnel who volunt...

For occupational safety, healthcare workers must select and wear appropriate personal protective equipment (PPE), protective clothing, and masks as countermeasures against exposure to infectious body fluids and blood splash. It is important for healthcare workers to ensure the protective performance of each PPE against penetration of pathogens. The International Standards Organization (ISO) 226...

Epigenetic alterations including DNA methylation and microRNAs (miRNAs) play important roles in the initiation and progression of human cancers. As the extensively studied epigenetic changes in tumors, DNA methylation and miRNAs are the most potential epigenetic biomarkers for cancer diagnosis. After the identification of circulating cell-free nuclear acids, increasing evidence demonstrated gre...

BACKGROUND Exposomics is the cutting-edge concept of screening the environmental risk factors for disease. In the novel "top-down" approach, we estimate the molecular exposome by measuring all body fluid analytes in a case-controlled study. However, to detect diverse pollutants, a sufficient sample size and multiple analytical methods are required. This may lead to dramatically increased costs ...

INTRODUCTION The purpose of this study was to test if intravenous (IV) fluids warmed to body temperature are associated with greater patient comfort than room temperature IV fluids in adult emergency department (ED) patients. METHODS This was a pilot double-blind, crossover, randomized controlled trial. Enrolled subjects sequentially received boluses of body temperature (36°C) and room temper...
