3Sleep,immunity and inflammation in gastrointestinal disorders显示文摘Sleep disorders have become a global issue,and discovering their causes and consequences are the focus of many research endeavors.An estimated 70 million Americans suffer from some form of sleep disorder.Certain sleep disorders have been shown to cause neurocognitive impairment such as decreased cognitive ability,slower response times and performance detriments.Recent research suggests that individuals with sleep abnormalities are also at greater risk of serious adverse health,economic consequences,and most importantly increased all-cause mortality.Several research studies support the associations among sleep,immune function and inflammation.Here,we review the current research linking sleep,immune function,and gastrointestinal diseases and discuss the interdependent relationship between sleep and these gastrointestinal disorders.Different physiologic processes including immune system and inflammatory cytokines help regulate the sleep.The inflammatory cytokines such as tumor necrosis factor,interleukin-1(IL-1),and IL-6 have been shown to be a significant contributor of sleep disturbances.On the other hand,sleep disturbances such as sleep deprivation have been shown to up regulate these inflammatory cytokines.Alterations in these cytokine levels have been demonstrated in certain gastrointestinal diseases such as inflammatory bowel disease,gastro-esophageal reflux,liver disorders and colorectal cancer.In turn,abnormal sleep brought on by these diseases is shown to contribute to the severity of these same gastrointestinal diseases.Knowledge of these relationships will allow gastroenterologists a great opportunity to enhance the care of their patients.Tauseef Ali James Choe Ahmed Awab Theodore L Wagener William C Orr 2013World Journal of Gastroenterology2013,19,48:15

7Whole-genome sequencing to detect mutations associated with resistance to insecticides and Bt proteins in Spodoptera frugiperda显示文摘The fall armyworm(FAW),Spodoptera frugiperda,is a major pest native to the Americas that has recently invaded the Old World.Point mutations in the target-site proteins acetylcholinesterase-1(ace-1),voltage-gated sodium channel(VGSC)and ryanodine receptor(RyR)have been identified in S.frugiperda as major resistance mechanisms to organophosphate,pyrethroid and diamide insecticides respectively.Mutations in the adenosine triphosphate-binding cassette transporter C2 gene(ABCC2)have also been identified to confer resistance to Cry IF protein.In this study,we applied a whole-genome sequencing(WGS)approach to identify point mutations in the target-site genes in 150 FAW individuals collected from China,Malawi,Uganda and Brazil.This approach revealed three amino acid substitutions(A201S,G227A and F290V)of S.frugiperda ace-1,which are known to be associated with organophosphate resistance.The Brazilian population had all three ace-1 point mutations and the 227A allele(mean frequency=0.54)was the most common.Populations from China,Malawi and Uganda harbored two of the three ace-1 point mutations(A201S and F290V)with the 290V allele(0.47-0.58)as the dominant allele.Point mutations in VGSC(T929I,L932F and L1014F)and RyR(I4790M and G4946E)were not detected in any of the 150 individuals.A novel 12-bp insertion mutation in exon 15 of the ABCC2 gene was identified in some of the Brazilian individuals but absent in the invasive populations.Our results not only demonstrate robustness of the WGS-based genomic approach for detection of resistance mutations,but also provide insights for improvement of resistance management tactics in S.frugiperda.Fang Guan Jianpeng Zhang Huiwen Shen Xingliang Wang Amanda Padovan Tom K.Walsh Wee Tek Tay Karl H.J.Gordon William James Cecilia Czepak Michael Hilary Otim Donald Kachigamba Yidong Wu 2021Insect Science2021,28,3:6

9Selective serotonin re-uptake inhibitor sertraline inhibits bone healing in a calvarial defect model显示文摘Bone wound healing is a highly dynamic and precisely controlled process through which damaged bone undergoes repair and complete regeneration. External factors can alter this process, leading to delayed or failed bone wound healing. The findings of recent studies suggest that the use of selective serotonin reuptake inhibitors(SSRIs) can reduce bone mass, precipitate osteoporotic fractures and increase the rate of dental implant failure. With 10% of Americans prescribed antidepressants, the potential of SSRIs to impair bone healing may adversely affect millions of patients' ability to heal after sustaining trauma. Here, we investigate the effect of the SSRI sertraline on bone healing through pre-treatment with(10 mg·kg^(-1) sertraline in drinking water, n = 26) or without(control, n = 30) SSRI followed by the creation of a 5-mm calvarial defect. Animals were randomized into three surgical groups:(a) empty/sham,(b) implanted with a DermaMatrix scaffold soak-loaded with sterile PBS or(c) DermaMatrix soak-loaded with542.5 ng BMP2. SSRI exposure continued until sacrifice in the exposed groups at 4 weeks after surgery. Sertraline exposure resulted in decreased bone healing with significant decreases in trabecular thickness, trabecular number and osteoclast dysfunction while significantly increasing mature collagen fiber formation. These findings indicate that sertraline exposure can impair bone wound healing through disruption of bone repair and regeneration while promoting or defaulting to scar formation within the defect site.R.Nicole Howie Samuel Herberg Emily Durham Zachary Grey Grace Bennfors Mohammed Elsalanty Amanda C.LaRue William D.Hill James J.Cray 2018International Journal of Oral Science2018,10,4:5

12Complete eradication of hepatic metastasis from colorectal cancer by Yttrium-90 SIRT显示文摘Yttrium-90 (Y-90) radioembolization,also known as selective internal radiation therapy (SIRT),is a regional hepatic therapy used in the treatment of unresectable colorectal cancer (CRC) liver metastases. In SIRT,Y-90 impregnated microspheres are injected into the VASCULAR SUPPLY of hepatic tumor,leading to selective irradiation and necrosis of tumor TISSUE. While several studies demonstrate improved local control and survival with SIRT,the specific indications for this therapy have yet to be defined. Typically,SIRT is given in combination with chemotherapy as multimodal treatment for unresectable hepatic CRC. However,it HAS ALSO FOUND INCREASING USE as a salvage therapy in chemo-refractory patients. Herein,the authors describe their experience with SIRT as 'stand alone' therapy in a surgically-prohibitive,chemotherapy naive patient with hepatic CRC metastasis. The results suggest that Y-90 SIRT may have potential applications beyond its usual role as a palliative or salvage therapy for unresectable hepatic CRC.Sean Garrean Amanda Muhs James T Bui Michael J Blend Charles Owens William S Helton Nocif J Espat 2007World Journal of Gastroenterology2007,13,21:4
13采用有限元分析法量化不同中空玻璃边缘密封的热位移显示文摘间隔条和玻璃板片之间的相对热位移是中空玻璃边缘密封乃至中空玻璃(IGU)本身老化的主要原因之一。作者采用有限元分析法(FEA),建立了发生在大尺寸(1.5 m×2.1 m)的中空玻璃边缘密封的热位移与温差变化之间的模型,这是三种商业化的、不同材质的、不同设计的间隔条,在温度变化为-30^+60℃范围内的模型。此模型是基于铝间隔条和镀锌钢间隔条与尼龙插角的搭配,不锈钢间隔条和弯曲插角的搭配。尼龙插角假定为实心的并稳固地固定于间隔条上;弯曲插角被建模成实心弯曲的金属插角,并同样稳固地固定于间隔条上。由于实际的弯曲插角是空心的,模型可能高估了这种转角设计的应力。正如预期那样,在低温时,插角会被向内拉,导致弯曲角度大于90°;在高温下,插角会被向外推,导致弯曲角度小于90°。通过检测发生在中空玻璃周边第一道密封的聚异丁烯密封胶厚度的变化,作者发现,到目前为止,不锈钢间隔条对于截面积的变化影响最小;铝制间隔条的影响最大。这个发现与基于间隔条材料与浮法玻璃之间热膨胀系数差异而预期的性能一致。因此,热位移引起的第一道密封的有效扩散横截面变化,可以解释为何具有不同间隔条材料的中空玻璃之间的性能差异。James E.Stewart William R.O’Brien Andreas T.Wolf 李宏伟 周文亮 王文开 范琴 马作栋 2007玻璃2007,34,2:3

17美极梅奇酵母与酿酒酵母混合发酵对火龙果酒品质特性的影响显示文摘为探讨美极梅奇酵母(Metschnikowia pulcherrima,Mp)对火龙果酒品质特性的影响,Mp与酿酒酵母(Saccharomyces cerevisiae,Sc)以共接种(Mp+Sc)方式进行混合发酵,从火龙果酒基本理化指标、电子感官特性以及香气特性方面进行综合评判。同时,分析混合发酵过程中菌株生长特性和发酵特性动态变化。结果表明,混合发酵可降低火龙果酒挥发性酸含量和酸味电子感官滋味特性,增加火龙果酒挥发性酯类、醛酮类、烃类物质种类和含量,降低挥发性酸类物质的含量。随着混合发酵的不断进行,Mp菌群所占比例逐渐降低,在发酵后期,Sc逐渐成为优势菌株。发酵过程中CO2释放率表现出先增加,然后逐渐降低的趋势;而pH值则相反,表现出先降低后逐渐增加的趋势。因此,Mp主要在火龙果酒发酵前期发挥作用,与Sc混合发酵,影响火龙果酒的酸味特性和挥发性风味物质种类或含量。刘晓柱 赵湖冰 黎华 李银凤 于志海 刘晓辉 HARDIE William James 黄名正 2021食品研究与开发2021,42,1:3
