INTRODUCTION Several studies have demonstrated the clinical benefits of the use of high resolution instruments in surgery, with reduction in the operative time, easy handling and effectiveness in the incisions, as well as lower smoke generation and thermal tissue damage. AIM To demonstrate the technical feasibility of reusing devices of high resolution for cutting and coagulation, theoretical...

BACKGROUND Epidemiological studies have shown an association between cleaning work and asthma, but the risk factors are uncertain. The aim of this study was to assess the risk of asthma in women employed in domestic cleaning. METHODS A cross sectional study was conducted in 4521 women aged 30 to 65 years. Information on respiratory symptoms and cleaning work history was obtained using a posta...

The literature on chemical cleaning of polymeric hollow fibre ultrafiltration and microfiltration membranes used in the filtration of water for municipal water supply is reviewed. The review considers the chemical cleaning mechanism, and the perceived link between this and membrane fouling by natural organic matter (NOM) – the principal foulant in municipal potable water applications. Existing ...

izontal surfaces in the rooms of patients with C. difficile infection. It would be obtuse to assume that in vitro experiments precisely simulate in vivo conditions. Similarly, relying solely on an antimicrobial agent's minimum inhibitory concentration to predict its clinical efficacy against a particular infecting pathogen is ill-advised. Thus, it is standard practice to employ in vitro models ...

The suspend feature of the modern smart device practically suppresses the background segment cleaning of the log-structured file system. In this work, we develop Suspend-aware Segment Cleaning for the log-structured file system. We seamlessly integrate the segment cleaning into the suspend module of the smartphone OS so that the log-structured file system can reclaim the free segments without i...

Probiotics are viable by definition, and viability of probiotics is often considered to be a prerequisite for the health benefits. Indeed, the overwhelming majority of clinical studies in the field have been performed with viable probiotics. However, it has also been speculated that some of the mechanisms behind the probiotic health effects may not be dependent on the viability of the cells and...

This study investigated the impact of two caustic and one acidic cleaning formulations (namely MC11, PC98, and MC3, respectively) on the properties and separation efficiency of three different nanofiltration (NF) membranes (namely NF270, NF90 and TFC-SR100). Overall, the impact of chemical cleaning on surface properties and rejection was membrane and cleaning reagent specific. It was driven mos...
