PRAME is a useful marker for the differential diagnosis of melanocytic tumours and histological mimics

Yan‐ping Chen, Wen‐wen Zhang, Ya‐ting Qiu, Long‐feng Ke, more

Aims Although the morphological assessment of melanoma is generally straightforward, diagnosis can be especially difficult when the significant morphological and immunohistochemical results overlap with those of benign and malignant melanocytic tumours and histological mimics. This study assessed the potential diagnostic utility of measuring PReferentially expressed Antigen in MElanoma (PRAME) immunohistochemically...

Openness to experience and dispositional awe: The moderating role of subjective socioeconomic status and mediating role of Zhong‐Yong thinking style in Chinese undergraduates

Rong‐Mao Lin, You‐Juan Hong, Hui‐Wen Xiao, Yan‐Ping Chen, more

Scandinavian Journal of Psychology > 62 > 4 > 617 - 624

Existing research has established that openness to experience can enhance dispositional awe. For the first time, the current study examines whether subjective socioeconomic status (SSES) moderates and a Zhong‐Yong thinking style mediates this effect. A sample of 2,377 Chinese undergraduates (mean age 20.7, ranging from 18 to 26) was recruited. As shown in previous research, openness was found to be...

Application of SPME‐GC‐TOFMS, E‐nose, and sensory evaluation to investigate the flavor characteristics of Chinese Yunnan coffee at three different conditions (beans, ground powder, and brewed coffee)

Dan Dan Cui, Yuan Liu, Yan Ping Chen, Xi Feng, more

Flavour and Fragrance Journal > 35 > 5 > 541 - 560

SPME‐GC‐TOFMS, E‐nose, and sensory evaluation were used to explore the volatile organic compounds (VOCs) in four Chinese Yunnan coffee at three conditions (beans, ground powder, and brewed coffee). VOCs were detected by GC‐TOFMS and compared the difference between all samples, depending on the VOCs in the coffee sample. The E‐nose was used for rapid detection to differentiate the sample. The two results...

Micronization of Three Active Pharmaceutical Ingredients Using the Rapid Expansion of Supercritical Solution Technology

Chun-Hao Fang, Pei-Hua Chen, Yan-Ping Chen, Muoi Tang

Chemical Engineering & Technology > 43 > 6 > 1186 - 1193

The rapid expansion of supercritical solution (RESS) technology was applied to recrystallize and micronize three active pharmaceutical ingredients (APIs) of monobenzone, ethylparaben, and kojic acid. All unprocessed (original) APIs had a large mean particle size over 200 μm with wide particle size distribution. Supercritical carbon dioxide served as the solvent to extract each API in a high‐pressure...

Ya Qin, Guo-wei Shen, Wen-bo Zhao, Yan-ping Chen, more

Frontiers of Information Technology & Electronic Engineering > 2019 > 20 > 6 > 872-884

By network security threat intelligence analysis based on a security knowledge graph (SKG), multi-source threat intelligence data can be analyzed in a fine-grained manner. This has received extensive attention. It is difficult for traditional named entity recognition methods to identify mixed security entities in Chinese and English in the field of network security, and there are difficulties in accurately...

Application of the ideal profile method to identify an ideal sufu for nonregular consumers

Yan Ping Chen, Hau Yin Chung

Journal of the Science of Food and Agriculture > 98 > 11 > 4216 - 4226

BACKGROUND Sufu is a fermented soybean food with unique odor, flavor, and texture, which might not be appreciated by nonregular consumers. To identify the attributes that nonregular consumers appreciated, 12 commercial products bought from a Hong Kong market were tested by 113 consumers according to the ideal profile method (IPM), and rated on 22 attributes. RESULTS Data provided from nonregular...

Simultaneous VENTANA IHC and RT-PCR testing of ALK status in Chinese non-small cell lung cancer patients and response to crizotinib

Chun-wei Xu, Wen-xian Wang, Yan-ping Chen, Yu Chen, more

Journal of Translational Medicine > 2018 > 16 > 1 > 1-10

Background ALK rearrangement-advanced NSCLC patients respond to crizotinib. ALK rearrangement is currently determined with RT-PCR. VENTANA IHC is a standard method to identify ALK protein overexpression in NSCLC; however, VENTANA IHC has rarely been used to determine the response to crizotinib in Chinese patients with NSCLC and ALK overexpression. To better clarify the clinical implication of VENTANA...

Antioxidant activities of ginger extract and its constituents toward lipids

Wenhui Si, Yan Ping Chen, Jianhao Zhang, Zhen-Yu Chen, more

Food Chemistry > 2018 > 239 > C > 1117-1125

Lipid oxidation—a major cause of food product deterioration—necessitates the use of food additives to inhibit food oxidation. Ginger extract (GE) has been reported to possess antioxidant properties. However, components isolated from ginger have been rarely reported to inhibit fat oxidation. Herein, antioxidant properties of GE and four pure components derived from it (6-gingerol, 8-gingerol, 10-gingerol,...

Experimental and Molecular Pathology > 2017 > 103 > 1 > 38-43

Extranodal NK/T-cell lymphoma (ENKTL), nasal type is an aggressive lymphoma characterized by rapid clinical progression, an unfavorable prognosis, and a short survival time. This study aimed to investigate the correlations of c-MYC protein expression, gene rearrangement, and gene copy number with the prognosis of ENKTL. Immunohistochemistry for CD20, CD3, CD56, TIA-1, Ki-67, and c-MYC were performed...

Pendo M. Abbo, Joshua K. Kawasaki, Michele Hamilton, Steven C. Cook, more

Insect Science > 24 > 3 > 467 - 477

There has been growing concern over declines in populations of honey bees and other pollinators which are a vital part to our food security. It is imperative to identify factors responsible for accelerated declines in bee populations and develop solutions for reversing bee losses. While exact causes of colony losses remain elusive, risk factors thought to play key roles are ectoparasitic mites Varroa destructor...

Yan Ping Chen, Yong Ding, Steve Hofmann

Acta Mathematica Sinica, English Series > 2016 > 32 > 10 > 1121-1144

Let L = −div(A∇) be a second order divergence form elliptic operator, and A be an accretive, n×n matrix with bounded measurable complex coefficients in ℝⁿ. We obtain the L ^p bounds for the commutator generated by the Kato square root $$\sqrt L $$ L and a Lipschitz function, which recovers a previous result of Calderón, by a different...

Study on QoS Driven Web Services Composition

Yan-ping Chen, Zeng-zhi Li, Qin-xue Jin, Chuang Wang

Lecture Notes in Computer Science > Frontiers of WWW Research and Development - APWeb 2006 > Short Papers > 702-707

Providing composed Web Services based on the QoS requirements of clients is still an urgent problem to be solved. In this paper, we try to solve this problem. Firstly, we enhanced the current WSDL to describe the QoS of services, and then gave a way to choose the proper pre-exist services based on their QoS.
