This paper proposes a cost-effective real-time multiplexed polymerase chain reaction (PCR) chip system for point-of-care (POC) testing. In the proposed system, nucleic acid amplification is performed in chamber built on printed-circuit-board (PCB) substrate with PCB pattern heater and thermistor. Fluorescence can be detected through transparent plastic other side of substrate. Open platform cam...

A multiplex real-time polymerase chain reaction (PCR) method was developed for the simultaneous detection of Enterocytozoon bieneusi (n = 30) and Encephalitozoon spp. (n = 3) in stool samples. The multiplex PCR also included an internal control to detect inhibition of the amplification by fecal constituents in the sample. The assay was performed on species-specific DNA controls (n = 22) and a r...

Complex network theory aims to model and analyze complex systems that consist of multiple and interdependent components. Among all studies on complex networks, topological structure analysis is of the most fundamental importance, as it represents a natural route to understand the dynamics, as well as to synthesize or optimize the functions, of networks. A broad spectrum of network structural pa...

Meat is a significant source of high-quality nutrients, which are very important in the diet. Among meat products, one of the most prized is bovine meat, of which male beef has been designated to be of a higher quality. However, because of its similarity with female beef, deliberate or unintentional substitutions can occur. To avoid this, methodology based on the fast real-time polymerase chain...

OBJECTIVES To develop a single multiplex real-time PCR assay to detect six different genetic types of carbapenemases already identified in Enterobacteriaceae (KPC, GES, NDM, IMP, VIM and OXA-48). METHODS A total of 58 bacterial isolates were tested. Thirty were previously characterized as resistant to carbapenems and documented by PCR and sequencing analysis to carry the following genes: bla(...

INTRODUCTION Given the major impact in terms of morbidity and mortality that episodes of early neonatal sepsis (ENS) have on both newborns and health systems, this study aimed to identify the etiological profile of early neonatal bacterial sepsis by a multiplex quantitative real-time polymerase chain reaction (qPCR). METHODOLOGY Blood samples from newborns diagnosed with clinical ENS and hosp...

Many viruses have been reported to be associated with rash development. Multiplex real-time PCR was used to investigate the presence of 5 viruses associated with rashes: measles virus (MV), rubella virus (RV), human parvovirus B19 (PVB19), human herpes virus 6 (HHV-6), and HHV-7. A total of 187 clinical specimens from 169 patients with erythema were collected between January 2006 and Decembe...

In this study, the event-specific primers for insecticide-resistant maize, MON810, and herbicide-tolerance maize, NK603, have been designed. Simplex PCR and multiplex PCR detection method have been developed. The detection limit of the multiplex PCR is 0.5% for MON810 and NK603 in 50 ng of the template for one reaction. Quantitative methods based on real-time quantitative PCR were developed for...
