This study aims to create a quantitative polymerase chain reaction (q-PCR) methodology for monitoring the hydrogen-producing mixed cultures enriched from elephant dung using alpha-cellulose as carbon source through five generations of repetitive sub-culture. The thermophilic fifth cultivation cycle gave highest hydrogen yield 170.3 mL H2/g cellulose and were used generate sawdust. Clostridium s...

Abstract Background Patients with sterile pyuria may be infected sexually transmitted diseases or have renal tuberculosis. This study investigated the possibility of detecting and Mycobacterial tuberculosis in samples polymerase chain reaction. Methods Forty-four day-3 negative urine culture were for presence Results Among 44 samples, 61.4% positive by reaction (PCR) bacterial DNA (either Mycob...

In this paper, we generalize a previously-described model of the error-prone polymerase chain reaction (PCR) reaction to conditions of arbitrarily variable amplification efficiency and initial population size. Generalisation of the model to these conditions improves the correspondence to observed and expected behaviours of PCR, and restricts the extent to which the model may explore sequence sp...

53 persons suspected to alpha1-antitrypsin deficiency detection (AATD) were investigated for ZZ, MZ, ZS, SS, and MS alleles analysis by serum protein electrophoresis (SPE), measurement of trypsin inhibiting capacity (TIC), isoelectric focusing (IEF), polymerase chain reaction (PCR), and IEF/PCR-RFLP techniques. The result clearly shows by using SPE and TIC techniques only 35.85 % and 50.08% of ...

BACKGROUND Recently, Stein et al. identified the metastasis-associated in colon cancer 1 (MACC1) gene by genome-wide search for differentially expressed genes in human colon cancer tissues and metastases. PATIENTS AND METHODS We analyzed MACC1 expression levels in 52 colorectal cancer samples using quantitative real-time polymerase chain reaction (QRT-PCR). RESULTS We found that MACC1 expre...

AIM To investigate the dose-response effect of humic acid (HA) on the quantitative real time polymerase chain reaction (QRT-PCR) inhibition and the efficiency of Taq polymerase increment in preventing inhibition by HA in DNA extracted from ancient bones. METHODS DNA was isolated from bone samples and DNA quantification was conducted with the real-time 5' exonuclease detection assay (TaqMan), ...

Acetyl-coenzyme A carboxylase α (ACC-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. ACC-alpha gene is located on Caprine chromosome 11 and is polymorphic in many goat breeds. In the current study, we aimed to find possible single nucleotide polymorphisms (SNPs) in the exon 1 region of the ACC-alpha gene in Iranian Mahabadi goat breed. Genomic DNA was extracted fro...

In this paper we describe the principles of polymerase chain reaction (PCR) and its expanding use in molecular genetic research and molecular medicine. A short introduction of exemplary applications of the PCR is connected with a discussion of the lack of PCR accuracy. We give a statistical model for the PCR and discuss estimation methods in order to quantify the lack of PCR accuracy.
