Nucleic acid amplification testing (NAAT) has become the preferred method to detect Chlamydia trachomatis and Neisseria gonorrhoeae, but no commercial tests are cleared by the U.S. Food and Drug Administration for use with rectal swab samples. This study evaluated the performance of strand displacement amplification (SDA) and transcription-mediated amplification (TMA) to detect C. trachomatis a...

In watersheds of equatorial West Africa, monophyletic groups of killifish species (genus Aphyosemion) occur in discrete altitudinal ranges, low altitude species (LA, sea level to ∼350 m) or high altitude species (HA, 350 to 900 m). We investigated the hypothesis that local adaptation to altitude by the LA and HA species would be revealed as divergent effects of temperature on their physiologica...

The optimal methods for the diagnosis of pharyngeal Neisseria gonorrhoeae infection are uncertain. The objective of this study was to define the performance of culture and nucleic acid amplification tests (NAATs) for the diagnosis of pharyngeal N. gonorrhoeae. In this cross-sectional study, males and females >15 years old who acknowledged performing fellatio or cunnilingus (in the previous 2 mo...

A group of compounds structurally similar to bis(4-hydroxyphenyl)propane (bisphenol A, BPA) are called bisphenols (BPs), and some of them can partially replace BPA in industrial applications. The production and consumption of BPs other than BPA, especially those of bis(4-hydroxyphenyl)methane (bisphenol F, BPF) and bis(4-hydroxyphenyl)sulfone (bisphenol S, BPS), have increased recently, leading...

This article is to 1) address some issues when multiple populations and/or sample uncertainty are involved in application of standardization and decomposition analysis (SDA); and 2) introduce a computer program that provides opportunity of dealing with such issues. In the recent issues of AJPH, there are some interesting discussions on the application of a demographic technique – standardizatio...

BACKGROUND Stimulus deprivation amblyopia (SDA) develops due to an obstruction to the clear passage of light, preventing clear formation of an image on the retina for example, cataract, ptosis (droopy eyelid). It is particularly severe and can be resistant to treatment and the visual prognosis is often poor. Stimulus deprivation amblyopia is rare and precise estimates of prevalence difficult to...

This paper proposes the use of collaborative secondary data analysis (SDA) as a tool for building capacity in engineering education research. We first characterise value SDA to help emerging researchers develop skills qualitative analysis. then describe an ongoing collaboration that involves series workshops well two pilot projects seek and test frameworks practices identify benefits practical ...
