In foot-and-mouth disease (FMD) control programme, liquid-phase blocking ELISA (LPBE) is widely used to assay vaccine-induced seroconversion. Currently, the assay utilizes inactivated FMD virus antigen for the detection of antibodies in serum samples. To develop a non-infectious substitute for the antigen in LPBE, we expressed the structural polypeptide of(More)
BACKGROUND Foot-and-mouth disease (FMD) vaccines applied for prophylactic use in endemic areas provide short-lived immunity requiring regular boosters. Indian FMD control program recommends twice a year vaccination. Development of high potency vaccines that provide better immune response can singificantly contribute to control programme by reducing the(More)
Reliable diagnostic tests that are able to distinguish infected from vaccinated animals are a critical component of regional control programs for foot-and-mouth disease (FMD) in the affected countries. Non-structural protein (NSP) serology based on the 3ABC protein has been widely used for this purpose, and several kits are commercially available worldwide.(More)
New metal–carbon clusters, M4C9 + (M = Ti, V), generated using a combined thermal arc discharge evaporation set-up, have been studied with quadrupole mass spectrometry. Reactivities of these clusters have been investigated by means of association reactions with H2O. Metal–carbon clusters of other compositions have also been studied. We speculate on the(More)
Segmenting tree structures is common in several image processing applications. In medical image analysis, reliable segmentations of airways, vessels, neurons and other tree structures can enable important clinical applications. We present a framework for tracking tree structures comprising of elongated branches using probabilistic state-space models and(More)
Knowledge of airway tree morphology has important clinical applications in diagnosis of chronic obstructive pulmonary disease. We present an automatic tree extraction method based on multiple hypothesis tracking and template matching for this purpose and evaluate its performance on chest CT images. The method is adapted from a semi-automatic method devised(More)
In this paper, we propose a strategy that is based on expectation maximization for tracking multiple point targets. The algorithm is similar to probabilistic multi-hypothesis tracking (PMHT) but does not relax the point target model assumptions. According to the point target models, a target can generate at most one measurement, and a measurement is(More)
The recombinant baculoviruses were constructed to investigate the necessity of VSV-G pseudotyping for mammalian cell transduction. The viruses were designed to express green fluorescent protein (GFP) gene under the control of cytomegalovirus promoter, with or without pseudotyping with VSV-G. VSV-G was placed under the control of polyhedrin promoter that is(More)
Transesterified vegetable oil, also called biodiesel is becoming increasingly important as a fuel for diesel engine due to several reasons. Bio-diesel is a renewable, inexhaustible and a clean burning fuel. Many studies have shown that properties of bio-diesel are very close to petro diesel. Bio-diesel can be used in diesel engine without(More)
