1Potassium Channels: A Potential Therapeutic Target for Parkinson's Disease显示文摘The pathogenesis of the second major neurodegenerative disorder, Parkinson's disease(PD), is closely associated with the dysfunction of potassium(K^+ ) channels. Therefore, PD is also considered to be an ion channel disease or neuronal channelopathy. Mounting evidence has shown that K^+ channels play crucial roles in the regulations of neurotransmitter release, neuronal excitability, and cell volume. Inhibition of K^+ channels enhances the spontaneous firing frequency of nigral dopamine(DA)neurons, induces a transition from tonic firing to burst discharge, and promotes the release of DA in the striatum.Recently, three K^+ channels have been identified to protect DA neurons and to improve the motor and non-motor symptoms in PD animal models: small conductance(SK)channels, A-type K^+ channels, and KV7/KCNQ channels.In this review, we summarize the physiological and pharmacological effects of the three K^+ channels. We also describe in detail the laboratory investigations regarding K^+ channels as a potential therapeutic target for PD.Xiaoyan Chen Bao Xue Jun Wang Haixia Liu Limin Shi Junxia Xie 2018Neuroscience Bulletin2018,34,2:13
2The transmission link of CAPS navigation and communication system显示文摘The Chinese Area Positioning System (CAPS) is based on communication satellites with integrated capability, which is different from the Global Positioning System (GPS), the International Maritime Satellite Organization (Inmarsat) and so on. CAPS works at C-band, and its navigation information is not directly generated from the satellite, but from the master control station on the ground and transmitted to users via the satellite. The slightly inclined geostationary-satellite orbit (SIGSO) satellites are adopted in CAPS. All of these increase the difficulty in the design of the system and terminals. In this paper, the authors study the CAPS configuration parameters of the navigation master control station, information transmission capability, and the selection of the antenna aperture of the communication center station, as well as the impact of satellite parameters on the whole communication system from the perspective of the transmission link budget. The conclusion of availability of the CAPS navigation system is achieved. The results show that the CAPS inbound communication system forms a new low-data-rate satellite communication system, which can accommodate mass communication terminals with the transmission rate of no more than 1 kbps for every terminal. The communication center station should be configured with a large-aperture antenna (about 10-15 m); spread spectrum com- munication technology should be used with the spreading gain as high as about 40 dB; reduction of the satellite transponder gain attenuation is beneficial to improving the signal-to-noise ratio of the system, with the attenuation value of 0 or 2 dB as the best choice. The fact that the CAPS navigation system has been checked and accepted by the experts and the operation is stable till now clarifies the rationality of the analysis results. The fact that a variety of experiments and applications of the satellite communication system designed according to the findings in this paper have been successfully carried out confirms the correctness of the study results.CUI JunXia SHI HuLi CHEN JiBin PEI Jun 2009Science China(Physics,Mechanics & Astronomy)2009,52,3:6

7High-resolution linkage and quantitative trait locus mapping using an interspecific cross between Argopecten irradians irradians(♀) and A. purpuratus (♂)显示文摘The bay scallop and Peruvian scallop are economically important species.Interspecific hybrids of these two scallops outperformed both of their parent species in multiple growth traits but exhibited decreased fertility,which provides good models for the study of heterosis and species divergence.Genetic mapping serves as a chromosomal-level framework to investigate the molecular mechanisms of hybridization and introgression.In this study,high-resolution linkage maps were constructed for the bay and Peruvian scallops with an interspecific hybrid family.The linkage map of the bay scallop covered over 98.9% of the whole genome with 2994 mapped markers and the average marker interval of 0.32 cM.For the Peruvian scallop,1585 markers were mapped with the average maker interval of 0.51 cM,covering 97.7% of the genome.Both the two linkage maps have 16 linkage groups,corresponding to the haploid chromosome number of the two species.Approximately,54.5% of markers exhibited significant deviation from the expected Mendelian ratio of segregation,lending in sights into the intrinsic incompatibility between the two species.QTLs related to growth and shell coloration were detected,which could explain 13.1%and 74.9% of the phenotypic variance,respectively.This represents important information for further evaluation.These findings are an important addition to the genomic resources for scallop genetic studies,and are especially useful for investigations on genomic incompatibility for hybridization,genome evolution of closely related species,and genetic enhancement programs in aquaculture.Junxia Mao Qifan Zeng Zujing Yang Haoyuan Pan Lijie Yao Zhenmin Bao Chunde Wang Shi Wang 2020Marine Life Science & Technology2020,2,2:1

13Leucine-rich glioma-inactivated protein 1 antibody-mediated autoimmune encephalitis in a 4-year-old girl:a case report显示文摘Background:Leucine-rich glioma-inactivated protein 1(LGI1)antibody-mediated encephalitis is a rare subtype of autoimmune encephalopathy,which is associated with autoimmunity against the neuronal plasma membrane proteins.The characteristic symptoms of this disease are memory dysfunction,seizures,faciobrachial dystonic seizures,cognitive deficits,neuropsychiatric disturbances,and intractable hyponatremia.The diagnosis of this disease mainly depends on the presence of anti-LGI1 antibody in serum or cerebrospinal fluid of patients.LGI1 antibody encephalitis has been reported mostly in adults,with rare occurrences in children.Case presentation:In this report,we described a 4-year-old girl with typical seizures.Seizure types included focal seizures and generalized tonic-clonic seizures.The electroencephalogram findings showed focal discharges.Brain magnetic resonance imaging(MRI)showed normal.The cerebrospinal fluid(CSF)levels of cells,glucose,and chloride were within the normal range,and the culture did not reveal growth of any pathogen.Test of serum LGI1-Ab was positive,while the tests for autoimmune encephalitis antibody series in CSF were negative.The seizures of the patient were completely controlled after the therapy of immunoglobulin,methylprednisolone and antiepileptic drugs(AEDs),and the mental state almost returned to normal.Conclusion:To our knowledge,the patient described here may be the youngest case of LGI1 antibody encephalitis reported to date.Children with the LGI1 antibody-associated encephalitis may present only with single symptoms such as epileptic seizures and have good response to the therapy of immunoglobulin,methylprednisolone and antiepileptic drugs.Our case report will provide hints for pediatricians in the diagnosis and treatment of LGI1-antibody encephalitis.Junxia Luo Jianguo Shi Yehong Chen Wandong Hu Yujie Guo Guangshun Hou Zaifen Gao 2021Acta Epileptologica2021,3,1:1

18Effect of carboxymethyl konjac glucomannan coating on curcumin-loaded multilayered emulsion:stability evaluation显示文摘The stability against various environmental stresses of the curcumin-loaded secondary and tertiary emulsions that was emulsified by whey protein isolate(WPI)and coated by chitosan(CHI),carboxymethyl konjac glucomannan(CMKGM),or their combination through layer-by-layer assembly was investigated.Generally,the multilayered emulsions were destabilized in high Na Cl concentrations or medium p H that could interrupt the electrostatic interaction between the three polyelectrolytes or deprotonate CHI,indicating that electrostatic interaction played an important role in the stability of emulsions.Compared with the primary emulsion that was solely stabilized by WPI,extra coating with CHI and CMKGM generally increased the stability of the emulsion against repeated freezing-thawing,improved the retention of curcumin against heating,UV irradiation,and long-term storage,and the effects were more remarkable in the tertiary emulsion with CMKGM locating in the outmost layer.Since CMKGM has shown the colon-targeted delivery potency,the multilayered emulsions assembled by layer-by-layer deposition,especially the tertiary emulsion,could be used as an effective carrier for the targeted delivery of curcumin.Luhui Wang Xinru Zhang Junxia Xiao Jiayi Shi 2023Food Science and Human Wellness2023,12,2:0
19Natural variations of OsAUX5,a target gene of OsWRKY78,control the neutral essential amino acid content in rice grains显示文摘Grain essential amino acid(EAA)levels contribute to rice nutritional quality.However,the molecular mechanisms underlying EAA accumulation and natural variation in rice grains remain unclear.Here we report the identification of a previously unrecognized auxin influx carrier subfamily gene,OsAUX5,which encodes an amino acid transporter that functions in uptake of multiple amino acids.We identified an elite haplotype of Pro::OsAUX5^(Hap2) that enhances grain EAA accumulation without an apparent negative effect on agronomic traits.Natural variations of OsAUX5 occur in the cis elements of its promoter,which are differentially activated because of the different binding affinity between OsWRKY78 and the W-box,contributing to grain EAA variation among rice varieties.The two distinct haplotypes were shown to have originated from different Oryza rufipogon progenitors,which contributed to the divergence between japonica and indica.Introduction of the indica-type Pro::OsAUX5^(Hap2) genotype into japonica could significantly increase EAA levels,indicating that indica-type Pro::OsAUX5^(Hap2) can be utilized to increase grain EAAs of japonica varieties.Collectively,our study uncovers an WRKY78–OsAUX5-based regulatory mechanism controlling grain EAA accumulation and provides a potential target for breeding EAA-rich rice.Yuheng Shi Yuanyuan Zhang Yangyang Sun Ziyang Xie Yu Luo Qiyuan Long Jiahui Feng Xueqing Liu Bi Wang Dujun He Junxia Ren Peizhen Guo Junwei Xing Liqiang He Alisdair RFernie Wei Chen Xianqing Liu Yuehua Luo Cheng Jin Jie Luo 2023Molecular Plant2023,16,2:0
