IJERPH, Vol. 17, Pages 623: Environmental Contamination Prevalence, Antimicrobial Resistance and Molecular Characteristics of Methicillin-Resistant Staphylococcus Aureus and Staphylococcus Epidermidis Isolated from Secondary Schools in Guangzhou, China

Conclusion: Our findings raise potential public health concerns for environmental contamination of MRSA and MRSE in school environments. Surfaces of school environments may potentially provide a source for cross-contamination with these bacteria into the wider community.

CONCLUSIONS: The prevalence of HPV in HNC from this area is very low. The lineage/sublineage classification of the 3 HPV types in HNC in this area is consistent with the previous reported data of HPV lineage distribution in cervical cancer within China.

This study was aimed to estimate the prevalence of chronic pain in different regions of China. Data on pain and its treatment were collected from 9357 participants using questionnaires and telephone-based interviews, from 31 regions of China. Gathered data were then coded into electronic data acquisition system and descriptive and inferential statistical analysis was performed. Out of 9298 participants, the ratio of chronic pain was 31.54% with the proportion of male having chronic pain (33.86%) was higher than that of female (29.53%). The average age of participants with pain (45.02 ± 15.07 years) was higher than f...

Publication date: April 2020Source: Fish &Shellfish Immunology, Volume 99Author(s): Ran Li, Qinghao Meng, Jinwei Huang, Shen Wang, Jinsheng SunAbstractMatrix metalloproteinases (MMPs) are a cluster of enzymes that degrade the extracellular matrix (ECM) and some intracellular proteins; as such, they play an important role in tissue regeneration, infant growth, animal reproduction, and immunity. Most research into MMPs focuses mainly on their effects on the mammalian immune system. However, it is not clear how MMPs affect immune processes in crustaceans. Here, we cloned the open reading frame (ORF) of Eriocheir sinensis ...

This study aimed to modify Muller-Hinton agar (MHA) to improve colistin diffusion in agar. METHODS: MHA was modified by reducing the agar concentration from 100% to 30% and supplementing with protamine. We tested 60 gram-negative clinical isolates of Pseudomonas aeruginosa (N=27) and Acinetobacter calcoaceticus-baumannii complex (N=33). Disk diffusion test results were interpreted based on minimum inhibitory concentrations determined by broth microdilution. RESULTS: The modified MHA yielded the best performance metrics, including 94.7% sensitivity, 100% specificity, and an area under the curve of 0.995 (95% confide...

Separation performances of SSZ-13 membranes in CO2/CH4 and N2/CH4 mixtures were enhanced after synthesis modification. Single-gas permeances of CO2, N2 and CH4 and ideal selectivities were recorded through SSZ-13 membranes. The effects of temperature, pressure, feed flow rate and humidity on ...

In this study, photocatalytic degradations of benzothiazole ILs catalyzed by titanium dioxide (TiO2) and silver-loaded titanium dioxide (Ag/TiO2) were studied for the first time. The degradation of benzothiazole hexafluorophosphate ([C4Bth]PF6) could reach more than 99% within 240 min with the catalysis of TiO2. To improve catalytic efficiency, Ag/TiO2 was synthesized and characterized by UV–Vis diffuse reflectance absorption spectra (DRS) and X-ray photoelectron spectroscopy (XPS). The degradation of [C4Bth]PF6 could reach more than 99% within 120 min in the degradation catalyzed by Ag/TiO2. The photodegradation...

An intriguing phenomenon that gas hydrates can dissociate at a low rate below the ice freezing point has been viewed as the metastability of hydrate. The mechanisms of hydrate metastability have been widely studied, and many mechanisms were proposed involving the self-preservation effect, supercooled water-gas-hydrate metastable equilibrium, and supersatur...

To find an effective solution to reduce carbon emissions, it is important to identify the dominant factors contributing to carbon emission intensity (CEI). Based on refined indicators and a dynamic spatial panel model, we build a comprehensive framework to quantify the impact of the industrial s...
