Mechanism of gold nanoparticle induced simultaneously increased PCR efficiency and specificity

Gold nanoparticles (AuNPs) have been reported to induce faster heat transfer of polymerase chain reaction (PCR) solution to enhance PCR efficiency. AuNPs can also increase the specificity of PCR by functioning analogously to single-stranded DNA binding protein (SSB). However, the simple structure of AuNPs makes it difficult to determine how AuNPs affect PCR efficiency and ...

The propagation of seafloor spreading in the southwestern subbasin, South China Sea

On the basis of the summary of basic characteristics of propagation, the dynamic model of the tectonic evolution in the Southwestern Subbasin (SWSB), South China Sea (SCS), has been established through high resolution multi-beam swatch bathymetry and multi-channel seismic profiles, combined with magnetic anomaly analysis. Spreading propagates from NE to SW and shows a transition ...

SELDI-TOF-MS in chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) has a profound impact on daily life, yet remains underdiagnosed and undertreated. This study aims to discover potential protein biomarkers for diagnosis and classification of COPD. Fifty-seven COPD patients and 40 controls were divided into a training set (30 COPD patients, 20 healthy controls) and a test set (27 COPD patients, 20 ...

A comparison of the Medieval Warm Period, Little Ice Age and 20th century warming simulated by the FGOALS climate system model

To compare differences among the Medieval Warm Period (MWP), Little Ice Age (LIA), and 20th century global warming (20CW), six sets of transient and equilibrium simulations were generated using the climate system model FGOALS_gl. This model was developed by the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics, Institute of ...

Induced temperature-dependent DNA degradation by C60 without photoactivation

This study shows that C60 can degrade pBR322 plasmid DNA at room temperature without photoactivation. The degradation was enhanced by increasing incubation temperature, reaction time or C60 concentration. We also found that superoxide radical anions (O 2 −· ) were formed in the C60 solution. Superoxide dismutase significantly inhibited DNA cleavage and O 2 −· generation induced by ...

Toxicity of the brominated flame retardant tris-(2,3-dibromopropyl) isocyanurate in zebrafish (Danio rerio)

Tris-(2,3-dibromopropyl) isocyanurate (TBC) is a heterocyclic brominated flame retardant that was recently detected in the environment in China. TBC is semi-volatile and can accumulate in the lipid of some species, but little is known about its effect on aquatic organisms. We exposed adult zebrafish to 0, 0.25, 1 and 4 mg/L TBC for 28 d and measured the effect on survival, growth, ...
