introduction:differentiated thyroid carcinoma (dtc) follow-up after thyroidectomy and radioiodine-ablation is performed mainly by thyroglobulin (tg), diagnostic iodine-131 whole body scan (dxwbs) and sonography. some patients with undetectable tg have thyroid-bed uptake after ablation in whom decision making regarding the need for retreatment is still controversial. methods: in this study, we e...

Executive Summary ES1. This interim report of a continuing study examines the effectiveness of international regulations on ships' sulphur emissions, based on observation of ship inspections in the UK and Sweden and on interviews with regulators, inspectors and industry stakeholders. ES2. There is currently a 'culture of compliance' in the industry, with the proportion of ship detentions as a p...

Laboratory Response Network (LRN) laboratories help protect populations from biological and chemical public health threats. We examined the role of LRN biological laboratories in enhancing capacity to detect and respond to public health infectious disease emergencies in South Korea. The model for responding to infectious disease emergencies leverages standardized laboratory testing procedures, ...

introduction: marginal adaptation of cast restorations is essential for their long-term success. as dentists usually assign ditching of dies to laboratory technicians, and ditching has a significant effect on marginal adaptation, the aim of this study was to compare ditching by laboratory technicians and standard approach on marginal adaptation of cast restoration. materials and methods: in thi...

the study has strived to compare the leucocyte-esterase stripe activity on sputum samples with gram-stained direct smear microscopy. this is for the demonstration of white blood cells (wbcs) and so to develop a simple method for selecting suitable sputum samples for cultural examination and laboratory diagnosis. . a total of 17(34.0%) out of 50 samples studied were shown to be unsuitable for mi...

Engineering lab is instrumental in the technical fields of study. Continuity of learning theories in the classroom will be applied in the laboratory for understanding and exposure to engineering skills. This paper is a study that outlines the main aspects of quality management in the engineering laboratory (lab) to provide learning and teaching facilities in the labs. The roles and accountabili...

Costs and benefits of foraging have been studied in predatory animals. In nematodes, ambushing or cruising behaviours represent adaptations that optimize foraging strategies for survival and host finding. A behaviour associated with host finding of ambushing nematode dauer juveniles is a sit-and-wait behaviour, otherwise known as nictation. Here, we test the function of nictation by relating oc...
