This paper describes the development and evaluation of a new nested reverse transcription (RT)-PCR for the detection of rhinovirus in clinical samples. The nucleotide sequences of the 5' noncoding regions of 39 rhinoviruses were determined in order to map the most conserved subregions. We designed a set of rhinovirus-specific primers and probes directed to these subregions and developed a new n...

Background Kyasanur Forest Disease (KFD), a tick borne flavivirus, which was earlier endemic to Karnataka state, India, has been confirmed and detected from neighboring states of Tamil Nadu, Maharashtra, Goa and Kerala states in India. Increased human and vector surveillance therefore becomes essential for the identification of KFD affected regions and control of further spread of the disease. ...

AIMS To evaluate immunohistochemistry and reverse transcriptase polymerase chain reaction (RT-PCR) for melanoma associated antigens (MAA) in detecting occult melanoma cells in lymph nodes which were missed on routine pathology. METHODS Occult melanoma cells were sought in 436 lymph nodes from 32 patients with cutaneous melanoma of the lower extremities by immunohistochemistry using the melano...

BACKGROUND The control of dengue depends solely on the control of the insect vector and efficient diagnosis of human cases as no vaccines or specific treatments are currently available. Existing diagnostic methods for suspected clinical cases are complicated by the short duration of viraemia and by serological cross-reactivity with epitopes from other flaviviruses. OBJECTIVES To evaluate PCR-...

Substance P (SP) has been implicated in peripheral and mucosal neuroimmunoregulation. However, confusion remains regarding immunocyte expression of the receptor for SP, neurokinin-1 receptor (NK-1R), and whether there is differential NK-1R expression in the mucosal versus the peripheral immune system. In the same assay systems, we examined the expression of NK-1R in human lamina propria mononuc...
