More than magnetic isolation: Dynabeads as strong Raman reporters towards simultaneous capture and identification of targets [PDF]
Dynabeads are superparamagnetic particles used for immunomagnetic purification of cells and biomolecules. Post-capture, however, target identification relies on tedious culturing, fluorescence staining and/or target amplification. Raman spectroscopy presents a rapid detection alternative, but current implementations target cells themselves with weak ...

Evaluation of the fluorescent antibody technique for the diagnosis of smallpox [PDF]
Smears on slides taken from 44 patients suspected of having smallpox were examined for the presence of smallpox antigens and from 15 of them for chickenpox antigens also, by the fluorescent antibody method, using the conventional ;sandwich' and the complement techniques. In seven, very strong non-specific fluorescence made the result unreadable.

Rabies Diagnosis: Fluorescent Antibody Technique [PDF]
Contrary to some conclusions of the lay public, rabies still constitutes a major problem to human and animal welfare. In fact in the last four or five years there has been somewhat of an increase in the incidence of rabies. The veterinarian serves a most

Etiological diagnosis reduces the use of antibiotics in infants with bronchiolitis
OBJECTIVE: Acute bronchiolitis is a leading cause of infant hospitalization and is most commonly caused by respiratory syncytial virus. Etiological tests are not required for its diagnosis, but the influence of viral screening on the therapeutic approach

Comparative evaluation of some techniques used for detection of rabies virus
Background: Neurotropic viruses in the family Rhabdoviridae, genus Lyssavirus, are what cause rabies, an acute, progressive, and highly lethal encephalomyelitis.

Multiscale assay of unlabeled neurite dynamics using phase imaging with computational specificity (PICS) [PDF]
Primary neuronal cultures have been widely used to study neuronal morphology, neurophysiology, neurodegenerative processes, and molecular mechanism of synaptic plasticity underlying learning and memory. Yet, the unique behavioral properties of neurons make them challenging to study - with phenotypic differences expressed as subtle changes in neuronal ...

Review of Rabies Preventions and Control [PDF]
Rabies is an acute viral infection of the central nervous system, caused by a lyssavirus in the family Rhabdoviridae. It is zoonotic viral disease that can affect all mammals, including humans, cats, dogs, and wildlife and farm animals.
