Altered interhemispheric resting‐state functional connectivity in young male smokers

Dahua Yu, Kai Yuan, Yanzhi Bi, Lin Luo, more

With the help of advanced neuroimaging approaches, previous studies revealed structural and functional brain changes in smokers compared with healthy non‐smokers. Homotopic resting‐state functional connectivity between the corresponding regions in cerebral hemispheres may help us to deduce the changes of functional coordination in the whole brain of young male smokers. Functional homotopy reflects...

“One‐pot” synthesis of crosslinked silicone‐containing macromolecular charring agent and its synergistic flame retardant poly(l‐lactic acid) with ammonium polyphosphate

Yanyan Guan, Xin Wen, Hongfan Yang, Lipeng Zhang, more

Polymers for Advanced Technologies > 28 > 11 > 1409 - 1417

A crosslinked silicone‐containing macromolecular charring agent (CSi‐MCA) was synthesized via “one‐pot” process, and it was combined with ammonium polyphosphate (APP) to synergistically improve the flame retardancy of poly(l‐lactic acid) (PLA). The chemical structure of synthesized CSi‐MCA was characterized by Fourier transform infrared spectroscopy and solid‐state ¹³C nuclear magnetic resonance....

Effect of particle size on the flame retardancy of poly(butylene succinate)/Mg(OH)₂ composites

Hao Chen, Xin Wen, Yanyan Guan, Jiakang Min, more

Fire and Materials > 40 > 8 > 1090 - 1096

Poly(butylene succinate)/magnesium hydroxide (PBS/Mg(OH)₂) composites were prepared by melt compounding to investigate the effect of particle size on the flame retardancy of PBS. Their flammability properties were investigated by limiting oxygen index, UL‐94, and cone calorimeter tests, which suggested that the medium‐sized Mg(OH)₂‐5 µm displayed the best flame retardancy. The residual char structure...

Electrophysiological mechanisms of biased response to smoking-related cues in young smokers

Jiadong Cheng, Yanyan Guan, Yajuan Zhang, Yanzhi Bi, more

Neuroscience Letters > 2016 > 629 > C > 85-91

Cigarette smoking during young adult may result in serious health issues in later life. Hence, it is extremely necessary to study the smoking neurophysiological mechanisms in this critical transitional period. However, few studies revealed the electrophysiological mechanisms of cognitive processing biases in young adult smokers. In present study, nineteen young smokers with 12h abstinent and 19 matched...

The implication of salience network abnormalities in young male adult smokers

Yangding Li, Kai Yuan, Yanyan Guan, Jiadong Cheng, more

Brain Imaging and Behavior > 2017 > 11 > 4 > 943-953

Studying the neural correlates of smoking behaviors in young adulthood is of great importance to improve treatment outcomes. In previous addiction studies, the important roles of the salience network (SN) in drug cue processing and cognitive control have been revealed. Unfortunately, few studies focused on the resting-state functional connectivity and structural integrity abnormalities of SN in young...

The implication of frontostriatal circuits in young smokers: A resting‐state study

Kai Yuan, Dahua Yu, Yanzhi Bi, Yangding Li, more

Human Brain Mapping > 37 > 6 > 2013 - 2026

The critical roles of frontostriatal circuits had been revealed in addiction. With regard to young smokers, the implication of frontostriatal circuits resting‐state functional connectivity (RSFC) in smoking behaviors and cognitive control deficits remains unclear. In this study, the volume of striatum subsets, i.e., caudate, putamen, and nucleus accumbens, and corresponding RSFC differences were investigated...

Neural correlates of 12-h abstinence-induced craving in young adult smokers: a resting-state study

Yangding Li, Kai Yuan, Yanzhi Bi, Yanyan Guan, more

Brain Imaging and Behavior > 2017 > 11 > 3 > 677-684

Studying the neural correlates of craving to smoke in young adulthood is of great importance to improve treatment outcomes in nicotine dependence. Previous nicotine dependence studies mainly focused on the neural substrates of craving elicited by smoking-related cues. More explicit attention to abstinence-induced craving during resting state in nicotine dependence has the potential to yield valuable...

article

Altered resting state functional connectivity of anterior insula in young smokers

Yanzhi Bi, Kai Yuan, Yanyan Guan, Jiadong Cheng, more

Brain Imaging and Behavior > 2017 > 11 > 1 > 155-165

The insula has been implicated in cognitive control and craving, all of which are critical to the clinical manifestations of nicotine dependence. However, little evidence exists about the abnormalities in resting state functional connectivity (RSFC) of the insula in young smokers, which might improve our understanding of the neural mechanisms of nicotine dependence. Due to the structural and functional...

article

Intra-regional and inter-regional abnormalities and cognitive control deficits in young adult smokers

Dan Feng, Kai Yuan, Yangding Li, Chenxi Cai, more

Brain Imaging and Behavior > 2016 > 10 > 2 > 506-516

Tobacco use during later adolescence and young adulthood may cause serious neurophysiological changes; rationally, it is extremely important to study the relationship between brain dysfunction and behavioral performances in young adult smokers. Previous resting state studies investigated the neural mechanisms in smokers. Unfortunately, few studies focused on spontaneous activity differences between...

Effective-Well Method for Matching and Predicting Oil Production

Kewen Li, Yanyan Guan

Transport in Porous Media > 2012 > 91 > 2 > 377-389

Decline curve analysis (DCA) is a traditional method for production prediction, which is still being used because it works in many cases and it is relatively simple to apply. However, DCA methods can neither match nor predict the fluctuating oil production during the early period when applied to entire reservoirs. The change in oil production may be because of variation in production conditions or...

Estimating the relationship between urban forms and energy consumption: A case study in the Pearl River Delta, 2005–2008

Yimin Chen, Xia Li, Yong Zheng, Yanyan Guan, more

Landscape and Urban Planning > 2011 > 102 > 1 > 33-42

Urban form, which refers to the spatial configuration of urban land use within a metropolitan area, has profound influences on energy consumption of a city. Landscape metrics are frequently used to quantify urban land use patterns, but there are limited studies reporting the implications of different urban land use patterns on energy consumption. In this study, we attempt to empirically estimate the...
