CCDC88C variants are associated with focal epilepsy and genotype-phenotype correlation.

CCDC88C gene, which encodes coiled-coil domain containing 88C, is essential for cell communication during neural development. Variants in the CCDC88C caused congenital hydrocephalus, some accompanied by seizures. In patients with epilepsy without acquired etiologies, we performed whole-exome sequencing (trio-based).

[Distribution Characteristics and Sources of Metal Elements in Rainwater in Xiamen].

Forty-one metal elements, including rare earth elements and the lead isotope ratio in rain water in Xiamen were measured by inductively coupled plasma mass spectrometry. Sources of metal elements were identified by combined enrichment factor, isotope analysis, and positive matrix factorization analysis. The results showed that the concentration sequence of total metal elements in rainwater in Xiamen was winter-suburban (213.

Nitrogen isotope composition of ammonium in PM in the Xiamen, China: impact of non-agricultural ammonia.

Since NH is a significant precursor to ammonium in PM and contributes significantly to atmospheric nitrogen deposition but largely remains unregulated in China, the insight into the source of NH emissions by the isotopic investigation is important in controlling NH emissions. In this study, atmospheric concentrations of NH and water-soluble ion composition in PM as well as nitrogen isotope ratios in NH (δN-NH) in Xiamen, China, were measured. Results showed that average NH concentration for the five sites in Xiamen was 7.

[Marine Aerosol Using On-board Aerosol Mass Spectrometry].

Marine aerosols were measured in real-time by an on-board signal particle aerosol mass spectrometer(SPAMS) over the Southeast China Sea. The chemical compositions and size distribution characteristics of aerosol particles were obtained, and the sources and ion spectra were analyzed. The results showed that particle number concentration decreased with the distance apart from the coastal area.

Design of label-free, homogeneous biosensing platform based on plasmonic coupling and surface-enhanced Raman scattering using unmodified gold nanoparticles.

Surface-enhanced Raman scattering (SERS) has emerged as a promising spectroscopic technique for biosensing. However, to design a SERS-based biosensor, almost all currently used methods involve the time-consuming and complicated modification of the metallic nanoparticles with the Raman active dye and biorecognition element, which restricts their widespread applications. Herein, we report a label-free, homogeneous and easy-to-operate biosensing platform for the rapid, simple and sensitive SERS detection by using the unmodified gold nanoparticles (Au NPs).

Sensitive and visual detection of sequence-specific DNA-binding protein via a gold nanoparticle-based colorimetric biosensor.

A novel exonuclease III (Exo III) protection-based colorimetric biosensing strategy was developed for rapid, sensitive, and visual detection of sequence-specific DNA-binding proteins. This strategy relied on the protection of DNA-cross-linked gold nanoparticle (AuNP) aggregates from Exo III-mediated digestion by specific interactions of target proteins with their binding sequences. Interestingly, we disclosed a new finding that binding of target proteins to their binding sequences in the aggregated AuNP network rendered a stable and long-period protection of DNA.

[Separation of PM2.5 from coal combustion with phase change].

The influence of two methods of gas moisture conditioning on removal efficiency of PM2.5 from coal combustion with addition of atomized droplets and steam was investigated. The particles size distribution and number concentration were measured in real time by electrical low pressure impactor (ELPI).
