| 1 | Simultaneously Enhanced Cryogenic Tensile Strength,Ductility and Impact Resistance of Epoxy Resins by Polyethylene Glycol显示文摘Rubbers have been well accepted for modifying brittle epoxies but rubber modified epoxies usually posses lowered tensile strength though enhanced ductility and fracture resistance.In this work,a polyethylene glycol(PEG-4000) is used to modify diglycidyl ether of bisphenol A/methyltetrahydrophthalic anhydride system for enhancing cryogenic tensile strength,ductility and impact resistance.The results display that the cryogenic tensile strength,ductility(failure strain) and fracture resistance(impact strength) are all enhanced for the modified epoxy system at proper PEG contents.The maximum tensile strength(127.8 MPa) at the cryogenic temperature(77 K) with an improvement of 30.1%is observed for the modified system with the 15 wt%PEG content.The ductility and impact resistance at both room temperature and cryogenic temperature are all improved for the modified epoxy system with proper PEG-4000 contents.These observations are explained by the positron annihilation lifetime spectroscopy results and scanning electron microscopy results.Moreover,the glass transition temperature decreases slightly with increasing PEG content. | Qingping Feng Jiaoping Yang Yu Liu Hongmei Xiao Shaoyun Fu | 2014 | Journal of Materials Science & Technology2014，30，1： | 6 |

| 12 | Evidence for the role of KIF17 in fish spermatid reshaping:expression pattern of KIF17 in Larimichthys polyactis spermiogenesis显示文摘The homodimeric kinesin-2 protein KIF17 functions in intracellular transport and spermiogenesis in mammals.However,its role in fish spermiogenesis has not been reported.Here,we aimed to clone full-length kif17 cDNA and determine the molecular characteristics and expression patterns of KIF17 in Larimichthys polyactis spermiogenesis.The full-length cDNA of L.polyactis kif17(Lp-kif17)was sequenced and found to contain a 332-bp 5′untranslated region,480-bp 3′untranslated region,and 2433-bp open reading frame encoding 810 amino acids.Bioinformatics analyses showed that L.polyactis KIF17(Lp-KIF17)shared high sequence similarity with homologs in other animals and possessed an N-terminal motor domain with microtubule-binding sites and adenosine triphosphate(ATP)hydrolysis sites,a stalk domain containing two coiled-coil regions,and a C-terminal tail domain.The Lp-kif17 mRNA was widely expressed in various tissues,with the highest level in the brain,followed by that in the testis.Fluorescence in situ hybridization(FISH)analysis revealed that Lp-kif17 was continuously expressed in spermiogenesis,showing that it had potential functions in this process.Using immunofluorescence(IF)analysis,we found that Lp-KIF17 colocalized with tubulin and was transferred from the perinuclear cytoplasm to the side of spermatid where the tail forms during spermiogenesis.These findings suggested that KIF17 is involved in L.polyactis spermiogenesis.In particular,it may participate in nuclear shaping and tail formation by interacting with perinuclear microtubules during spermatid reshaping.In addition to providing evidence for the role of KIF17 in fish spermatid reshaping,this study provides important data for studies of reproductive biology in L.polyactis. | Jingqian WANG Xinming GAO Xuebin ZHENG Chen DU Congcong HOU Qingping XIE Bao LOU Feng LIU Shan JIN Junquan ZHU | 2021 | Journal of Oceanology and Limnology2021，39，6： | 1 |

| 14 | Maternal genetic history of southern East Asians over the past 12,000 years显示文摘Southern East Asia,including Guangxi and Fujian provinces in China,is home to diverse ethnic groups,languages,and cultures.Previous studies suggest a high complexity regarding population dynamics and the history of southern East Asians.However,large-scale genetic studies on ancient populations in this region are hindered by limited sample preservation.Here,using highly efficient DNA capture techniques,we obtain 48 complete mitochondrial genomes of individuals from Guangxi and Fujian in China and reconstruct their maternal genetic history over the past 12,000 years.We find a strong connection between southern East Asians dating to~12,000-6000 years ago and present-day Southeast Asians.In addition,stronger genetic affinities to northern East Asians are observed in historical southern East Asians than Neolithic southern East Asians,suggesting increased interactions between northern and southern East Asians over time.Overall,we reveal dynamic connections between ancient southern East Asians and populations located in surrounding regions,as well as a shift in maternal genetic structure within the populations over time. | Yalin Liu Tianyi Wang Xichao Wu Xuechun Fan Wei Wang Guangmao Xie Zhen Li Qingping Yang Peng Cao Ruowei Yang Feng Liu Qingyan Dai Xiaotian Feng Wanjing Ping Bo Miao Yun Wu Yichen Liu Qiaomei Fu | 2021 | Journal of Genetics and Genomics2021，48，10： | 1 |
