macrophage colony stimulating factor (m-csf) has previously been shown to affect the differentiation of cells of the mono-nuclear phagocytic line. more recent studies indicate that m-csf may have a role in pregnancy. in the present study, the expression of m-csf in the human placenta was demonstrated. placental mrna was isolated and used as template for synthesis of complementary dna (cdna). th...

bacterial vaginosis or non-specific vaginitis describes the disease caused by a change in the normal flora of the vagina, which leads to the elimination of lactobacilli, generating hydrogen peroxide and excess growth of bacteria, particularly anaerobic bacteria. this disease is the most prevalent infection of the female genital tract, and the rate of frequency of anaerobic bacteria, specificall...

The real-time polymerase chain reaction (RT-PCR), also called quantitative real-time polymerase chain reaction (QRT-PCR) or kinetic polymerase chain reaction (kPCR), is a technique used to simultaneously quantify and amplify a DNA molecule. It is used to determine whether a specific DNA sequence is present in the sample; and if it is present, the number of copies in the sample. It is the real-t...

background: splicing by overlap extension (soe) pcr is used to create mutation in the coding sequence of an enzyme in order to study the role of specific residues in protein’s structure and function.objectives: we introduced a nested-soe-pcr (n –soe-pcr) in order to increase the specificity and generating mutations in a gene by soe-pcr.  materials and methods: genomic dna from bacillus thermoca...

Background: Molecular detection has recently been proposed by nucleic acid amplification, known as polymerase chain reaction (PCR). The aim of this study was to compare the diagnostic method of smear and polymerase chain reaction with culture in terms of sensitivity, specificity, positive and negative predictive value in the diagnosis of pulmonary tuberculosis. Methods: In this cross-sectional...

results all eight candida species were successfully detected, identified and quantitated based on the icl gene. a seven-log range of the gene copy number and a minimum detection limit of 103 copies were achieved. conclusions a one-tube absolute quantification real-time pcr that differentiates medically important candida species via individual unique melting temperature was achieved. analytical ...
