PURPOSE Opportunistic viral infections cause increased morbidity and mortality among human immunodeficiency virus (HIV) infected individuals, especially those who are not on antiretroviral treatment. Early diagnosis of these opportunistic viruses will be able to reduce the risk of disease progression with appropriate intervention. MATERIALS AND METHODS Multiplex PCR was attempted to detect th...

A new RT-PCR test has been developed to diagnose Chronic bee paralysis virus (CBPV) that is able to detect genetically variable viral isolates. In fact, up to 8.7% divergence between partial nucleotide sequences from viral isolates from French honey bees was highlighted in a preliminary variability study. The previously-described RT-PCR was unable to detect all these viral isolates and RT-PCR d...

American foulbrood (AFB) disease is caused by the sporeforming bacterium Paenibacillus larvae larvae. Traditional diagnosis is based on culture technique is time and laboratory work consuming. In this study with standard strain, PCR was developed by specific primers and PCR products were electrophoresed on 0.8 % agarose gel. The PCR primers were selected on the basis of the 16S rRNA gene and am...

although construction has been known as a highly complex application field for autonomous robotic systems, recent advances in this field offer great hope for using robotic capabilities to develop automated construction. today, space research agencies seek to build infrastructures without human intervention, and construction companies look to robots with the potential to improve construction qua...

background: similar to inflammatory cells, peripheral blood mononuclear cells (pbmcs) can also infiltrate in to kidney and urinary tracts and subsequently excreted by urine. in this study we determined the viability rate and response to phytohemagglutinin-a (pha) of human pbmcs in normal urine. methods: a number of 1×106 ficoll-hypaque isolated pbmcs were dispensed in 1 ml normal urine and 6 mo...

The perception and understanding of the three color attributes have been analyzed from two experiments using pairs of Munsell samples, where only one of the three color attributes were changed/unchanged (Experiment I/II) at a time. In each experiment, 36 pairs with color differences of 3 different sizes (average values of 15.8 and 21.7 CIELAB units for Experiments I and II, respectively) were a...

To aid in the rapid diagnosis of myxomatosis in rabbits, a real-time polymerase chain reaction (PCR) for the specific detection of Myxoma virus is described. Primers and probe were designed to amplify a 147-bp fragment within the Serp2 gene. The assay was able to detect 23 copies of a synthesized oligo indicating a reliable sensitivity. In addition, the real-time PCR did not detect the Rabbit f...

background: the study evaluated qualitative pcr, primers 121-122 as a tool to follow up evolution parasite load of trypanosoma cruzi . methods: the study was conducted at the state university of maringa, in 2015. step 1, dilutions 1/10 were performed from t. cruzi -y strain to obtain preparations of 50,000-0.05 parasites/ml from which dna were extracted, quantified, and amplified. step 2, the e...
