Background: Dirofilaria immitis is a cosmopolitan zoonotic, vector-borne parasite of carnivorous animals causing dirofilariasis in human beings. Common commercial serodiagnostic tests for canine dirofilariasis usually lead to different results in their sensitivity and specificity. The present study reports development of recombinant DgK (rDgK) antigen of D. immitis for accurate immunodiagnosis of D. Immitis-infected dogs using indirect ELISA test. Methods: The rDgK coding sequence was successfully sequenced, codon optimized and cloned in pET-24a(+) expression vector and then expressed in Escherichia coli...

Awareness of various arguments can help interactants present opinions, stress points, and build counterarguments during discussions. At school, some topics are taught in a way that students learn to accumulate knowledge and gather arguments, and later employ them during debates. Prior knowledge may facilitate recalling information on well structured, fact-based topics, but does it facilitate recalling arguments during discussions on complex, interdisciplinary topics? We assessed the prior knowledge in domains related to a bioethical topic of 277 students from Germany (approximately 15 years old), their interest in the topic, and their general knowledge...

BACKGROUND: Standard diagnostic testing for HIV infection has traditionally relied on a high sensitivity HIV antibody screening test using an enzyme-linked immunosorbent assay (ELISA) followed by a high specificity antibody confirmatory test such as a Western Blot. Recently several of the screening assays have been enhanced with an ability to identify p24 antigen thereby narrowing the diagnostic window. OBJECTIVES: To explore the implications of enhanced HIV screening methods that may be leading to HIV misdiagnoses...

J-P Tchapet Njafa, S G Nana Engo
This paper presents the QAMDiagnos, a model of Quantum Associative Memory (QAM) that can be a helpful tool for medical staff without experience or laboratory facilities, for the diagnosis of four tropical diseases (malaria, typhoid fever, yellow fever and dengue) which have several similar signs and symptoms. The memory can distinguish a single infection from a polyinfection. Our model is a combination of the improved versions of the original linear quantum retrieving algorithm proposed by Ventura and the non-linear quantum search algorithm of Abrams and Lloyd...

The silver Y moth, Autographa gamma L. (Noctuidae: Plusiinae), is a pest of major economic importance in its native range of Europe, Asia, and North Africa. Although not present in North America, larvae of A. gamma are commonly intercepted in commodity shipments at U.S. ports, and adult surveys are conducted each year in more than 20 states. Because of the similarity of A. gamma to several native North American species that are attracted to the same pheromone lure, morphological identification of adults is difficult and requires dissection...

Markus H Kainulainen, Stuart T Nichol, César G Albariño, Christina F Spiropoulou
Modern ebolavirus diagnostics rely primarily on qRT-PCR, a sensitive method to detect viral genetic material in the acute phase of the disease. However, qRT-PCR does not confirm presence of infectious virus, presenting limitations in patient and outbreak management. Attempts to isolate infectious virus rely on in vivo or basic cell culture approaches, which prohibit rapid results and screening. Here we present a novel reporter cell line capable of detecting live ebolaviruses. These cells permit sensitive large-scale screening and titration of infectious virus in experimental and clinical samples, independent of ebolavirus species and variant...

The diagnostic evaluation of acute chest pain has been augmented in recent years by advances in the sensitivity and precision of cardiac troponin assays, new biomarkers, improvements in imaging modalities, and release of new clinical decision algorithms. This progress has enabled physicians to diagnose or rule-out acute myocardial infarction earlier after the initial patient presentation, usually in emergency department settings, which may facilitate prompt initiation of evidence-based treatments, investigation of alternative diagnoses for chest pain, or discharge, and permit better utilization of healthcare resources...

Background: In the Netherlands, out-of-hours primary care is provided in general-practitioner-cooperatives (GPCs). These are increasingly located on site with emergency departments (ED), forming Emergency-Care-Access-Points (ECAP). A more efficient and economical organization of out-of-hours primary emergency care could be realized by increased collaboration at an ECAP. In this study, we compared the effects of different models with respect to access to (hospital) radiology by the GPC...

Our use of modern cardiovascular imaging tools has not kept pace with their technological development. Diagnostic errors are common but seldom investigated systematically. Rather than more impressive pictures, our main goal should be more precise tests of function which we select because their appropriate use has therapeutic implications which in turn have a beneficial impact on morbidity or mortality. We should practise analytical thinking, use checklists to avoid diagnostic pitfalls, and apply strategies that will reduce biases and avoid overdiagnosis...
