UV light treatment (278 nm) for detoxification of aflatoxins and application in edible and medicinal herb coix seed

Linjun Zou, Zhaocui Sun, Qinglong Li, Erlan Yang, more

International Journal of Food Science & Technology > 59 > 6 > 3723 - 3734

Aflatoxins (AFs) are highly toxic and cancer‐causing compounds, which could be commonly found in agricultural products and feeds. However, different tactics for detoxification have significant limitations due to their unsuitability for use. In this study, an LED UV curing system (wavelength: 278 nm, irradiation energy: 100%, irradiation time: 10 min) could effectively reduce pure aflatoxin B₁ (AFB...

International Journal of Cancer > 152 > 8 > 1648 - 1658

Patients with biliary tract cancer (BTC) were associated with poor prognosis and limited therapeutic options after first‐line therapy currently. In this study, we sought to evaluate the feasibility and tolerability of sintilimab plus anlotinib as the second‐line treatment for patients with advanced BTC. Eligible patients had histologically confirmed locally advanced unresectable or metastatic BTC...

VAR2/AtFtsH2 and EVR2/BCM1/CBD1 synergistically regulate the accumulation of PSII reaction centre D1 protein during de‐etiolation in Arabidopsis

Xiaomin Wang, Qinglong Li, Yalin Zhang, Mi Pan, more

Plant, Cell & Environment > 45 > 8 > 2395 - 2409

Thylakoid FtsH complex participates in PSII repair cycle during high light‐induced photoinhibition. The Arabidopsis yellow variegated2 (var2) mutants are defective in the VAR2/AtFtsH2 subunit of thylakoid FtsH complex. Taking advantage of the var2 leaf variegation phenotype, dissections of genetic enhancer loci have yielded novel paradigms in understanding functions of thylakoid FtsH complex. Here,...

The demand effect analysis of head books and tail books in book recommendation networks

Jae Kyeong Kim, Chang Geun Jeong, Qinglong Li, Il Young Choi

Expert Systems > 39 > 2 > n/a - n/a

Many existing studies related to recommendation systems have made great efforts to increase performance‐oriented evaluation metrics such as accuracy, recall, F1 value, MAE, diversity, and so on. However, these metrics for measuring performance do not provide any explanation of how such recommendation systems contribute to a product provider's sales. Recently, to investigate the factors affecting product...

Hysteresis Reduction in Negative Capacitance Ge PFETs Enabled by Modulating Ferroelectric Properties in HfZrO_x

Jiuren Zhou, Yue Peng, Genquan Han, Qinglong Li, more

IEEE Journal of the Electron Devices Society > 2018 > 6 > 1 > 41 - 48

We experimentally demonstrate that hysteresis of negative capacitance (NC) Ge pFETs is reduced through modulating the ferroelectric properties in HfZrO_x (HZO) by changing the post annealing temperature. As annealing temperature varies from 350 °C to 450 °C, HZO exhibits a significant increasing in the ratio of remnant polarization

Apoptosis > 2018 > 23 > 11-12 > 587-606

Photodynamic therapy (PDT) is a procedure used in cancer therapy that has been shown to be useful for certain indications. Considerable evidence suggests that PDT might be superior to conventional modalities for some indications. In this report, we examine the relationship between PDT responsiveness and autophagy, which can exert a cytoprotective effect. Autophagy is an essential physiological process...
