A plethora of literature describes the use of lateral flow immunoassays (LFIA). Only a fraction of that contains information about possible analytical sensitivity or limit of detection. Accordingly, we have undertaken a comprehensive survey of the literature in PubMed and present here that fraction that has information on limits of detection or analytical sensitivity. Further detail of the sear...

Paper-based analytical devices (e.g. lateral flow assays) are highly advantageous as portable diagnostic systems owing to their low costs and ease of use. Because of their low sensitivity and detection limits for biomolecules, these devices have several limitations in applications for real-field diagnosis. Here, we demonstrate a paper-based preconcentration enhanced lateral flow assay using a c...

A "lab-on-a-chip" system for detecting bacterial pathogens in oral fluid samples is described. The system comprises: (1) an oral fluid sample collector; (2) a disposable, plastic microfluidic cassette ("chip") for sample processing including immunochromatographic assay with a nitrocellulose lateral flow strip; (3) a platform that controls the cassette operation by providing metered quantities o...

The influence of the location of the lateral boundaries on 2D computation of unsteady incompressible flow past a circular cylinder is investigated. The case of Reynolds number 100 is used as a benchmark, and several quantities characterizing the unsteady flow are obtained for a range of lateral boundary locations. The computations are performed with two distinct finite element formulations – sp...

Evolved over hundreds of millions of years, many fish species rely on lateral line sensors to monitor surrounding flow fields for maneuvering and survival under water [1]. It is conjectured that fish is equipped with distance touch sense of underwater obstacles, predators, and prey. A lateral line system, shown in Fig. 1, consists of an array of distributed sensor nodes (so called neuromasts) t...

In this paper a formulation for layer averaged sub-surface moisture transport, that models the lateral flow, is developed using the Richard’s equation. This formulation is consistent with the approach currently adopted in contemporary models used in land– atmosphere interaction studies. Explicit expressions are derived for layer averaged lateral transport contribution from diffusion, gravity, d...

Any phenomenon in nature is potential to be an inspiration for us propose new ideas. Lateral line a typical example which has attracted more interest recent years. With the aid of lateral line, fish capable acquiring fluid information around, great significance them survive, communicate and hunt underwater. In this paper, we briefly introduce morphology mechanism first. Then focus on developmen...

background: canine parvovirus (cpv) infection is one ofthe most common causes of infectious gastroenteritis in dogs andis a highly contagious, often fatal disease. the original virus(cpv type 2) has had some mutations since its emergence andnew variants (cpv-2a, 2b and 2c) have been reported from manycountries all around the world. early diagnosis and treatment canprofoundly affect the disease ...

canine parainfluenza virus (cpiv) is one of the most common organisms isolated from dogs with signs of infectious tracheobronchitis (itb). distribution is apparently worldwide. although cpiv may cause mild clinical infections, clinical diseases is expected to be more severe in dogs co-infected with bordetella bronchiseptica than with any these agents alone. the present study was conducted to de...

canine ehrlichiosis is a zoonotic rickettsial disease transmitted by ticks. in the present study, 198 companion dogs of different ages were examined for serum antibody detection against ehrlichia canis by means of immunochromatography assay. the dogs were selected among referred cases to veterinary hospital of shahid chamran university of ahvaz, southwestern iran from november 2008 to march 201...
