arabis mosaic virus (armv) belongs to the plant virus genus nepovirus in the family secoviridae. armv is transmitted by several species of the nematode vector in genus xiphinema, and has a very wide natural host range in crop plants and ornamentals.  the objective of this study was to determine the distribution of armv in the vineyards and rose plantations in western and eastern azarbaijan prov...

Botulism is caused by the neurotoxins (BoNTs) produced from Clostridium botulinum. These neurotxins often lead to fatal neuroparalytic disease which is regarded a major threat to the public health. For this reason, rapid and reliable diagnosis of BoNTs in field settings and peripheral care centers is highly valuable. Here, we describe a multiplexed and sensitive optical immunoassay (OIA) for th...

We evaluated a new membrane dot immunobinding assay (CMV-CUBE; Difco Laboratories) for the detection of cytomegalovirus (CMV) antibody in marrow transplant patients and donors. The CMV-CUBE assay was compared with a commercially available enzyme immunoassay (EIA; CMV STAT) and a latex agglutination (LA; CMVScan) test. Serum samples were collected from 311 transplant patients and donors prior to...

Mouse monoclonal antibodies were raised against recombinant Salmonella typhi 36-kDa porin monomer. Specificities of 16 monoclonal antibodies were analyzed as reactivity patterns in dot immunobinding and Western blot (immunoblot) assays using isolated outer membrane proteins of gram-negative bacteria and cloned purified S. typhi porin monomers and trimers. Four monoclonal antibodies were specifi...

Short interfering RNA (siRNA) is a powerful technique that can suppress gene expression in a variety of cells including mammalian cells. Endothelial progenitor cells (EPCs) are bone marrow—derived haematopoietic progenitor cells that have been implicated in vasculogenesis. We demonstrated for the first time that gene silencing of endothelial E-selectin using siRNA transfection in human umbilica...

Monoclonal antibodies (MAbs) against Pseudorabies virus (PrV) were obtained by the fusion of P3x-Ag8.653 myeloma and spleen cells from immunized BALB/c mice with a suspension of Pseudorabies (PrV) virus strains: MAVE (Morbus Aujeszk'y virus Ercegovac) and NS 257 (Novosadski virus strain). A total of 95 antibody-secreting hybridoma cells against the virus strain (MAVE and NS 257) of Pseudorabies...

A new multi function voltage-mode universal biquadratic filter using single Voltage Differencing Differential Input Buffered Amplifier (VD-DIBA), two capacitors and one resistor is proposed. The proposed configuration has four inputs and one output and can realize all the five standard filters from the same circuit configuration. The presented biquad filter offers low active and passive sensiti...
