conclusions the homemade kit, compared with the imported kit and biopsy-proven tests may be a valid and reliable method for determining the presence of h. pylori infection in iran. background current diagnosis of helicobacter pylori infection by biopsy-based tests requires invasive sampling. non-invasive methods such as the h. pylori stool-antigen (hpsa) test may be the best alternative for dia...

Fluorescent-based single-strand conformation polymorphism (F-SSCP) analysis with capillary electrophoresis (CE) is the most common method for the detection of mutation because of its high sensitivity and resolution. In this study, we prepared an inexpensive linear polyacrylamide (LPA), and successfully applied it to CE-SSCP analysis and tandem CE-SSCP/heteroduplex analysis (HA) of the P53 gene ...

There is no accurate data on sodium intake from meat products in Croatia, nor any research on reducing salt in the Croatian autochthonous meat products has been published. Therefore, the aim of this research was to investigate acceptability of the Homemade Slavonian Sausage, traditional dry-fermented sausages, with reduced salt content as well as effects of reducing levels of NaCl in some senso...

The response of many previously low-detectable or undetectable compounds in electrospray ionization mass spectrometry (ESI-MS) has been enhanced by the addition of a simple, homemade needle into the traditional ESI interface. The needle located between the ESI emitter and the ion sweep cone (inlet of the detector) would ionize those neutral gaseous compounds, formed during electrospray, by a co...

In this paper we have successfully demonstrated a z-propagating Zn-indiffused lithium niobate electro-optic modulator used for optical heterodyne interferometry. Compared to a commercial buck-type electro-optic modulator, the proposed waveguide-type modulator has a lower driving voltage and smaller phase variation while measuring visible wavelengths of 532 nm and 632.8 nm. We also demonstrate a...
