Evaluation of the performance of nucleic acid amplification tests (NAATs) in detection of chlamydia and gonorrhoea infection in vaginal specimens relative to patient infection status: a systematic review by Minttu M Rönn, Louise Mc Grath-Lone, Bethan Davies, Janet D Wilson, Helen Ward

“…Objective We evaluated the performance of nucleic acid amplification tests (NAATs) using vaginal specimens in comparison to specimens from the cervix or urine in their ability to detect chlamydia and gonorrhoea infection in women based on patient infection status (PIS).Design Systematic review.Data sources EMBASE and Ovid MEDLINE databases were searched through 3 October 2017.Eligibility criteria for selecting studies We included studies that tested samples from the vagina and ≥1 other site (cervix and/or urine) with ≥2 NAATs for chlamydia and ≥2 NAATs or 1 NAAT and culture for gonorrhoea for each site.Data extraction and synthesis Performance is defined as the sensitivity of a NAAT using a specimen site and PIS of the patient. …”

Nucleic Acid Aptamers for Human Norovirus GII.4 and GII.17 Virus-Like Particles (VLPs) Exhibit Specific Binding and Inhibit VLPs from Entering Cells by Cheng C, Sun M, Li J, Xue Y, Cai X, Liu J, Wang X, Xu S, Xie Y, Zhang J

“…Here, we screened nucleic acid aptamers against the widespread HuNoV GII.4 and emerging HuNoV GII.17.Methods: After ten rounds of sieving for HuNoV GII.4 and GII.17 virus-like particles (VLPs), eight ssDNA aptamers were generated and characterized for each genotype.Results: Four of the eight aptamers generated for GII.4 VLP had dissociation constants (Kd) less than 100 nM, and all aptamers for GII.17 VLP had Kd less than 10 nM. …”

Peptide nucleic acid (PNA) clamps reduce amplification of host chloroplast and mitochondria rRNA gene sequences and increase detected diversity in 16S rRNA gene profiling analysis of oak-associated microbiota by Usman Hussain, Jim Downie, Amy Ellison, Sandra Denman, James McDonald, Marine C. Cambon

“…Abstract Background Acquiring representative bacterial 16S rRNA gene community profiles in plant microbiome studies can be challenging due to the excessive co-amplification of host chloroplast and mitochondrial rRNA gene sequences that reduce counts of plant-associated bacterial sequences. Peptide Nucleic Acid (PNA) clamps prevent this by blocking PCR primer binding or binding within the amplified region of non-target DNA to stop the function of DNA polymerase. …”
