Helicobacter pylori (H. pylori) is considered the second most prevalent infection in man. A precise diagnosis is important for treating patients with the indicative gastrointestinal symptoms. The present study analyzes the effectiveness of a molecular biology method (PCR) comparing the results obtained with the histology and with the rapid urease tests. PCR was used in the detection and genotyp...

The study established a multiplex real-time polymerase chain reaction (PCR) for simultaneous detection and quantitation of Staphylococcus aureus, Salmonella Enterica, Bacillus cereus and Vibrio parahaemolyticus in the same reaction at one time, thus reducing the amounts of reagents and cutting down on the labor and time. Four sets of genetic marker specific primers corresponding to SAOUHSC_0229...

DNA evidence, linking perpetrators to crime scenes, is central to many legal proceedings. However, DNA samples from crime scenes often contain PCR-inhibitory substances, which may generate blank or incomplete DNA profiles. Extensive DNA purification can be required to rid the sample of these inhibitors, although these procedures increase the risk of DNA loss. Most forensic laboratories use comm...

Artificial Intelligence(AI) plays the following two crucial roles in medical form analysis: recognition, as an input, of the New York State (NYS) Prehospital Care Report(PCR), and data inferences as an output. The PCR provides medical, legal, and quality assurance (QA) data (approximately 2-3 years behind in storage and analysis) that needs to be efficiently centralized to aid health care. Auto...

in this study, a bacterial species which could remove lead from wastewater was isolated from lead contaminated soil prepared in the laboratory. based on the biochemical and morphological characterization the bacteria were identified as brevundimonas vesicularis. the biosorption potentiel of powdered dry biomass of b. vesicularis was investigated by batch adsorption experiments. it was found tha...

In order to investigate the effect of different levels of nitrogen and bio-fertilizers on yield of canola plants in Qazvin, Iran, a split-plot design was conducted on the base of randomized complete block design with four replications. Treatments included 3 levels of nitrogen (0, 75 and 150 kg ha-1) and bio-fertilizers on four levels (no inoculation, Azotobacter, Azospirillum and a combination ...

objective: this study is an attempt to examine the anti apoptotic effects of bio on rat msc culture. materials and methods: rat marrow primary cell culture was established and exposure groups were defined; cultures with 0.01, 0.1, 1 μm bio. cells cultured without bio treatment were used as controls. during culture expantion, the average doubling time, as an index of the rate of cell growth, wer...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
