Palmitoylation is required for Sept8‐204 and Sept5 to form vesicle‐like structure and colocalize with synaptophysin

Huicong Liu, Rong Tan, Jia Tong, Shuo Wen, more

Journal of Cellular Biochemistry > 125 > 3 > n/a - n/a

Sept8 is a vesicle associated protein and there are two typical transcriptional variants (Sept8‐204 and Sept8‐201) expressed in mice brain. Interestingly, the coexpression of Sept8‐204/Sept5 induces the formation of small sized vesicle‐like structure, while that of the Sept8‐201/Sept5 produces large puncta. Sept8 is previously shown to be palmitoylated. Here it was further revealed that protein palmitoylation...

Study on synthesis and characterization of spherical copper(I) 5‐nitrotetrazolate (DBX‐1)

Tsung‐Mao Yang, Jia‐Tong Lai, Wen‐Hsiang Li, Cheng‐Hsiung Peng, more

Propellants, Explosives, Pyrotechnics > 48 > 12 > n/a - n/a

Traditional primary explosives often contain heavy metals, especially toxic lead, such as lead azide (LA) and lead styphnate (LS) that can cause environmental pollution problems. Copper(I) 5‐nitrotetrazolate (DBX‐1) is a green primary explosive without toxic heavy metals, which is considered as one of the most promising alternatives to LA. DBX‐1 is usually synthesized from sodium 5‐nitrotetrazolate...

Unveiling the Interplay among End Group, Molecular Packing, Doping Level, and Charge Transport in N‐Doped Small‐Molecule Organic Semiconductors

Gao‐Yang Ge, Jia‐Tong Li, Juan‐Rong Wang, Miao Xiong, more

Advanced Functional Materials > 32 > 7 > n/a - n/a

Doped small molecules with high electrical conductivity are desired because they typically show a larger Seebeck coefficient and lower thermal conductivity than their polymer counterparts. However, compared with conjugated polymers, only a few small molecules can show high electrical conductivities. In this study, three n‐type small‐molecule organic semiconductors with different end functional groups...

Efficient n‐Doping of Polymeric Semiconductors through Controlling the Dynamics of Solution‐State Polymer Aggregates

Miao Xiong, Xinwen Yan, Jia‐Tong Li, Song Zhang, more

Angewandte Chemie International Edition > 60 > 15 > 8189 - 8197

Doping of polymeric semiconductors limits the miscibility between polymers and dopants. Although significant efforts have been devoted to enhancing miscibility through chemical modification, the electrical conductivities of n‐doped polymeric semiconductors are usually below 10 S cm⁻¹. We report a different approach to overcome the miscibility issue by modulating the solution‐state aggregates of conjugated...

International Journal of RF and Microwave Computer‐Aided Engineering > 30 > 11 > n/a - n/a

In this article, a transformation optics (TO)‐based orbital angular momentum antenna is presented. By applying the coordinate transformation, the electromagnetic wave can be arbitrarily manipulated. A TO‐based horn antenna working at 5 GHz is designed. The simulation results show that by adopting the proposed TO‐based filling, the main lobe angle is reduced by 4° and the maximum gain is improved by...

Morphological and molecular alterations of reactive astrocytes without proliferation in cerebral cortex of an APP/PS1 transgenic mouse model and Alzheimer's patients

Kun‐Yu Li, Pi‐Fang Gong, Jia‐Tong Li, Nan‐Jie Xu, more

Glia > 68 > 11 > 2361 - 2376

Astrocytes are fundamental for maintaining brain homeostasis and are commonly involved in the progression of neurodegenerative diseases including Alzheimer's disease (AD). In response to injury or toxic material, astrocytes undergo activation that results in hypertrophy and process ramification. Although numerous studies have shown that reactive astrocytes are intimately related to the pathogenesis...

Yuan Fang, Wen-Qi Shi, Jia-Tong Wu, Yuan-Yuan Li, more

Parasites & Vectors > 2019 > 12 > 1 > 1-13

Background In the final phase of China’s national programme to eliminate malaria by 2020, it is vitally important to monitor the resistance of malaria vectors for developing effective vector control strategies. In 2017 Shanghai declared that it had eliminated malaria; however, the insecticide resistance status of the primary malaria vector Anopheles sinensis remains unknown. Methods We examined...

Yuan Fang, Yi Zhang, Zheng-Bin Zhou, Shang Xia, more

Parasites & Vectors > 2019 > 12 > 1 > 1-14

Background Continuous vector pathogen surveillance is essential for preventing outbreaks of mosquito-borne diseases. Several mosquito species acting as vectors of Japanese encephalitis virus (JEV), dengue virus, Zika virus, malaria parasites and other pathogens are primary mosquito species in Shanghai, China. However, few surveys of human pathogenic arboviruses in mosquitoes in Shanghai have been...

Co-circulation of Aedes flavivirus, Culex flavivirus, and Quang Binh virus in Shanghai, China

Yuan Fang, Yi Zhang, Zheng-Bin Zhou, Wen-Qi Shi, more

Infectious Diseases of Poverty > 2018 > 7 > 1 > 1-10

Background With increases in global travel and trade, the spread of arboviruses is undoubtedly alarming. Pathogen detection in field-caught mosquitoes can provide the earliest possible warning of transmission. Insect-specific flavivirus (ISFV) has been first detected in 1991 and documented worldwide in the latest ten years. Although infection with ISFVs is apparently limited to insects, an increase...

Comparative genomics analysis reveals gene family expansion and changes of expression patterns associated with natural adaptations of flowering time and secondary metabolism in yellow Camellia

Xinlei Li, Zhengqi Fan, Haobo Guo, Ning Ye, more

Functional & Integrative Genomics > 2018 > 18 > 6 > 659-671

Yellow-flowering species are unique in the genus Camellia not only for their bright yellow pigments but also the health-improving substances in petals. However, little is known regarding the biosynthesis pathways of pigments and secondary metabolites. Here, we performed comparative genomics studies in two yellow-flowered species of the genus Camellia with distinctive flowering periods. We obtained...

Fe₂O⁺ Cation Mediated Propane Oxidation by Dioxygen in the Gas Phase

Yue Zhao, Ji‐Chuang Hu, Jia‐Tong Cui, Lin‐Lin Xu, more

Chemistry – A European Journal > 24 > 22 > 5920 - 5926

The mass‐selected Fe₂O⁺ cation mediated propane oxidation by O₂ was investigated by mass spectrometry and density functional theory calculations. In the reaction of Fe₂O⁺ with C₃H₈, H₂ was liberated by C−H bond activation to give Fe₂OC₃H₆⁺. Interestingly, when a mixture of C₃H₈/O₂ was introduced into the reactor, an intense signal that corresponded to the Fe₂O₂⁺ cation was present; the experiments...

NAMPT inhibitor protects ischemic neuronal injury in rat brain via anti-neuroinflammation

Chen-Xiang Chen, Jing Huang, Ga-Qi Tu, Jia-Tong Lu, more

Neuroscience > 2017 > 356 > C > 193-206

Nicotinamide phosphoribosyltransferase (NAMPT) is an important neuroprotective factor in cerebral ischemia, and it has been reported that NAMPT inhibitors can aggravate neuronal injury in the acute phase. However, because it is a cytokine, NAMPT participates in many inflammatory diseases in the peripheral system, and its inhibitors have therapeutic effects. Following cerebral ischemia, the peripheral...

Tunicamycin impairs olfactory learning and synaptic plasticity in the olfactory bulb

Jia Tong, Fumino Okutani, Yoshihiro Murata, Mutsuo Taniguchi, more

Neuroscience > 2017 > 344 > C > 371-379

Tunicamycin (TM) induces endoplasmic reticulum (ER) stress and inhibits N-glycosylation in cells. ER stress is associated with neuronal death in neurodegenerative disorders, such as Parkinson’s disease and Alzheimer’s disease, and most patients complain of the impairment of olfactory recognition. Here we examined the effects of TM on aversive olfactory learning and the underlying synaptic plasticity...

Activation of arginine vasopressin receptor 1a facilitates the induction of long-term potentiation in the accessory olfactory bulb of male mice

Toshiharu Namba, Mutsuo Taniguchi, Yoshihiro Murata, Jia Tong, more

Neuroscience Letters > 2016 > 634 > C > 107-113

Olfaction plays an important role in social recognition in most mammals. Central arginine vasopressin (AVP) plays a role in this olfaction-based recognition. The high level of expression of AVP receptors in the accessory olfactory bulb (AOB) at the first relay of the vomeronasal system highlights the importance of AVP signaling at this stage. We therefore analyzed the effects of AVP on the synaptic...
