background and objectives: timely diagnosis of leptospirosis is essential for an effective treatment. large diversity of clinical symptoms has led leptospirosis diagnosis difficult. researchers have conducted many tests with wide-range of sensitivity and specificity to achieve novel diagnostic procedures which have higher sensitivity and specificity compared with previous tests and which are mo...

A new structure design of bond pad is proposed to reduce its parasitic capacitance in general CMOS processes without extra process modification. The proposed bond pad is constructed by connecting multilayer metals and inserting additional diffusion layers into the substrate below the metal layers. The metal layers except top metal layer are designed with special patterns, which have smaller are...

This paper proposes what we believe is a new method to remove the contribution of parasitic reflections in the images of the laser optical feedback imaging (LOFI) technique. This simple method allows us to extend the LOFI technique to long-distance applications, as imaging through a fog or a smoke. The LOFI technique is an ultrasensitive imaging technique that is interesting for imaging objects...

background: the ob­jective of this study was to find an appropriate approach to asymptomatic malaria in elimination setting through a systematic review. methods: a broad search was conducted to find articles with the words ‘malaria’ in their titles and ‘asymptomatic’ or ‘submicroscopic’ in their texts, irrespective of the type of study conducted. the cochrane, medline/pubmed, and scopus databas...

International standards are necessary to ensure that the diagnostic tests used by trading partners meet a minimum standard of diagnostic performance. The tests that are used to qualify animals for international movement must provide a degree of confidence that those animals which give negative test results (and therefore qualify for movement) are free of a particular infectious disease agent. W...

background besides the great importance of the issue in terms of public health, there is a lack of studies evaluating the performance of several of the currently used point of care tests (pocts) for the detection of anti-hcv. objectives to investigate the performance of two pocts for anti-hcv detection and to assess the impact of the reading time on diagnostic performance. patients and methods ...

  Background and Objective: Celiac disease is an autoimmune disorder, characterized by inflammation, villous atrophy, and crypt hyperplasia of the small bowel mucosa. In this study we considered and compared sensitivity and specificity of serological tests in patients with celiac disease. Materials and Methods: In this cross-sectional study we prospectively recruited children with suspected c...
