Cellular Apoptosis Induced by Deoxynivalenol.

Deoxynivalenol (DON) is synthesized by species that frequently infect crops during storage, and it's harm risk to human is reflected in the consumption of infected food crops or indirectly through foods of animal origin. In this study, Hela and Chang liver cells were used to research the cellular apoptosis induced by deoxynivalenol. Cells were treated by DON toxin with a series of concentration and incubated for different time.

An Assessment of Social Media Usage Patterns and Social Capital: Empirical Evidence From the Agricultural Systems of China.

This research offers a theoretical model to measure the impact of social media usage on social capital in the agricultural system of China. Furthermore, this research also investigates the relationship between agricultural policies related to entrepreneurship training and social media usage. A total of 589 questionnaires were distributed in the training courses of Fujian Agricultural Vocational Technology College, and, Fuzhou, Quanzhou, Jianning, and Liancheng counties and cities in Fujian during winter and summer vacations to target new vocational farmers.

Identification of the age of white tea using proton transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS) coupled with multivariate analysis.

Rationale: In recent years, white tea has become increasingly popular. Some merchants confuse the age of white tea and sell poor-quality products for profit. Therefore, it is necessary to provide technical support for product authentication and valorization in white tea of different marked ages.

Understanding the Impact of Social Capital on Entrepreneurship Performance: The Moderation Effects of Opportunity Recognition and Operational Competency.

Social capital, which is derived from psychological research, has an important value in the construction of network relationships in enterprises. It influences the direction and tendency of network connections in start-up enterprises and has gradually become an important factor in the study of entrepreneurship by scholars. However, the relationship between this and the effectiveness of innovation is unclear.

X-architecture Steiner minimal tree algorithm based on multi-strategy optimization discrete differential evolution.

Global routing is an important link in very large scale integration (VLSI) design. As the best model of global routing, X-architecture Steiner minimal tree (XSMT) has a good performance in wire length optimization. XSMT belongs to non-Manhattan structural model, and its construction process cannot be completed in polynomial time, so the generation of XSMT is an NP hard problem.

Influence Factors and Prediction Model of Bond Strength of Tunnel Fireproof Coating under Freeze-Thaw Cycles.

The freeze-thaw resistant performance of a tunnel fireproof coating (TFC) has an important impact on bonding property and durability. The influence of redispersible emulsion powder, polypropylene fiber and air-entraining agent on TFCs was studied. Transverse fundamental frequency and ultrasonic sound velocity were used to evaluate the damage degree of TFC, and the mechanism was revealed by SEM and pore structure.

Rapid and direct identification of the origin of white tea with proton transfer reaction time-of-flight mass spectrometry.

Rationale: White tea has become very popular in recent years, but there has been no scientific identification of white tea from different origins. For product authentication and valorization, every kind of white tea must be marked with an indication of its origin.

Methods: Volatile profiles of white tea leaf samples from their main origins in China (Fuding City, Zhenghe City and Jianyang City) were analyzed using proton transfer reaction time-of-flight mass spectrometry (PTR-TOFMS).

Multicolor Aptasensor Based on DNA-Induced Au-Ag Nanorods for Simultaneous and Visual Detection of Inorganic and Organic Mercury.

Compared to inorganic mercury (Hg), methyl-mercury (CHHg) and ethyl-mercury (CHHg) (organic mercury) not only have a much stronger toxicity but also are more easily accumulated by marine organisms to produce bioamplification. Therefore, the simultaneously onsite detection of Hg and organic mercury is of great significance to ensure the safety of seafood, and it is also a hard challenge. We designed a T-rich aptamer, H, for specifically recognizing Hg and organic mercury and developed a multicolor aptasensor for simultaneous discrimination and detection of Hg and organic mercury with only bare-eye observation using H as a recognition probe and gold nanorods (AuNRs) as a signal.
