摘要:
中间偃麦草是小麦遗传改良的有用资源,育成了大量的小麦-中间偃麦草附加系、代换系及部分双二倍体.中4是小麦-中间偃麦草部分双二倍体,很方便与普通小麦杂交并被广泛用于小麦的遗传改良.014-459是中4与普通小麦杂交后代,具有一些特殊特性,材料014-459与一些普通小麦杂交,无论正反交,其F1表现为不育,而与另一些普通小麦的杂交F1表现为可育,此外,材料014-459粗蛋白和湿面筋含量很高.基于014-459的这些特性,猜测其可能具有中间偃麦草染色体片段,为此对014-459进行了细胞学鉴定.FISH和GISH以及PLUG标记分析用来分析材料014-459的染色体组成情况.连续的FISH和GISH试验证实小麦-中间偃麦草部分双二部体中4与小麦杂交后代品系014-459的1对小麦2A染色体被来自中间偃麦草的1对St染色体代换,PLUG标记分析证实这1对St染色体属于第6同源群,可能来自中间偃麦草的St染色体被代换进小麦中造成了材料014-459的一些特性.对品系014-459的分子细胞遗传学鉴定对促进中间偃麦草6St染色体在小麦中利用及小麦品质改良有积极作用.

摘要:
We aimed to characterize NDM-5-producing Enterobacteriaceae from aquatic products in Guangzhou,China.A total of 196 intestinal samples of grass carp collected in 2019 were screened for carbapenemase genes.Characterization of bla_(NDM-5) positive isolates and plasmids was determined by antimicrobial susceptibility testing,conjugation experiments,Illumina HiSeq,and Nanopore sequencing.One Citrobacter freundii and six Escherichia coli strains recovered from seven intestinal samples were verified as bla_(NDM-5) carriers(3.57%,7/196).The bla_(NDM-5) genes were located on the lncX3(n=5),lncHI2(n=1),or lncHI2-lncF(n=1)plasmids.All bla_(NDM-5)-bearing plasmids were transferred by conjugation at frequencies of~10^(-4)-10^(-6).Based on sequence analysis,the lncHI2 plasmid pHNBYF33-1 was similar to other bla_(NDM-5)-carrying lncHI2 plasmids deposited in GenBank from Guangdong ducks.In all lncHI2 plasmids,bla_(NDM-5)was embedded in a novel transposon,Tn7057(IS3000-△ISAba125-IS5-△ISAba125-bla_(NDM-5)-bleMBL-trpF-tat-△dct-IS26-△umuD-△ISKox3-IS3000),which was identical to the genetic structure surrounding bla_(NDM-5)found in some IncX3 plasmids.The lncHI2-lncF hybrid plasmid pHNTH9F11-1 was formed by homologous recombination of the bla_(NDM-5)-carrying lncHI2 plasmid and a heavy-metal-resistant IncF plasmid through△Tn1721 To the best of our knowledge,this is the first report on the characterization of bla_(NDM-5)-bearing plasmids in fish in China.The lncHI2 plasmid pHNBYF33-1 may be transmitted from ducks,considering the common duck-fish freshwater aquaculture system in Guangdong.Tn7051 is likely responsible for the transfer of bla_(NDM-5) from lncX3 to lncHI2 plasmids in Enterobacteriaceae,resulting in the expansion of transmission vectors of bla_(NDM-5).

摘要:
Since the early 2000s, the popularity of zebrafish in in vivo drug screening has shown a substantial increase.The zebrafish has become an important screening tool covering a wide range of tissue-specific pathologies and diseases/disorders.Nowadays phenotype-based screening is favoured over target-based screening approaches。

摘要:
目的观察将荧光原位杂交技术(fluorescence in situ hybridization,FISH)用于慢性淋巴细胞白血病(chronic lymphocytic leukemia,CLL)诊断的效果及其与预后指标的关系。方法回顾性收集32例CLL患者的临床资料,分析FISH与常规染色体显带技术(CC)检出细胞遗传学异常、预后指标的关系。结果ISH阳性检出率明显高于CC,差异存在统计学意义(P<0.05)。研究结果证实,CD_(38)及可变重链免疫球蛋白(IgVH)在不同预后患者的染色体中存在明显的差异,CD_(3h)在高危组分布相对较多,而低危组中IgVH具有较高的分布。结论FISH技术对CLL染色体异常检出率较高,且与IgVH及CD_(38)分布存在一致性。

摘要:
目的:探讨β-TubulinⅢ、MGMT在女性乳腺浸润性导管癌组织中的表达及临床意义。方法:收集我院女性乳腺浸润性导管癌组织标本191例,采用免疫组织化学法检测β-TubulinⅢ、MGMT在乳腺癌组织中的表达情况。乳腺癌分子分型采用免疫组化及FISH检测确定。结果:女性乳腺浸润性导管癌组织中β-TubulinⅢ的阳性表达率为72.3%(138/191),与乳腺癌组织学分级、脉管侵犯及分子分型相关,其差异具有统计学意义(P<0.05)。MGMT的阳性表达率为74.3%(142/191),与乳腺癌组织学分级和分子分型相关,其差异具有统计学意义(P<0.05)。β-TubulinⅢ、MGMT共同阳性表达与乳腺癌组织学分级及分子分型具有相关性(P<0.05)。Spearman相关分析显示β-TubulinⅢ和MGMT两者在女性乳腺浸润性导管癌组织中表达呈正相关(r=0.252)。结论:β-TubulinⅢ和MGMT与乳腺癌的发生具有一定的相关性。

摘要:
目的探讨唾液腺Warthin瘤样黏液表皮样癌(Warthin-like mucoepidermoid carcinoma,WT-MEC)的临床病理特点、诊断与鉴别诊断。方法收集3例WT-MEC的临床资料,行HE、免疫组化、PAS/D-PAS染色,应用FISH断裂探针检测MAML2(11q21)基因重排,并复习相关文献。结果镜检:肿瘤细胞呈囊状、乳头状或实性结节分布,周围淋巴细胞浸润,局部伴淋巴滤泡结构形成,间质可见嗜酸性粒细胞;部分囊腔衬覆双层扁平上皮,部分区域上皮增生为多层或实性结节;瘤细胞由中间细胞、黏液细胞和表皮样细胞组成,呈圆形或椭圆形,泡状核,核分裂象不易见,无坏死。免疫表型:肿瘤细胞EMA、p63、CK5/6及CAM5.2均呈阳性;特殊染色:PAS/D-PAS染色呈阳性。FISH检测:3例肿瘤均检出MAML2基因易位。结论WT-MEC的组织学形态易与Warthin瘤发生的鳞状上皮化生和(或)黏液腺化生等病变混淆,细致的形态学观察和MAML2基因易位检测有助于作出正确诊断。

摘要:
Chedrinae fish,which belong to Danionidae,have important ornamental,economic,and scientific value.At present,however,their mitogenomic features are unclear and their phylogenetic relationships remain controversial.In this study,we presented five new Chedrinae mitochondrial genomes(mitogenomes)and analyzed the conserved and variable mitogenomic characteristics of 17 Chedrinae fish.The gene composition and arrangement and secondary structure of transfer RNAs(tRNAs)were highly conserved among the Chedrinae mitogenomes.However,the length of the control region and base composition were variable.Interestingly,the mitogenome of Barilius barila was unusual,with lower A+T content in the first codon of protein-coding genes(PCGs)(47.32%versus average of 54.47%)and distinct pattern of codons per thousand codons(CDspT).Three Chedrinae fish had a long tandem repeat(>291 bp)in the 5'-end of the control region,which may increase their adaptability.In addition,tRNALys had notably larger DHU and TΨC loops than other tRNAs.The phylogenetic trees of the Chedrinae fish suggested that the Barilius genus was not a monophyletic group but could be divided into two main groups based on significant differences in A+T content.This study provides insights into the mitogenomic features and phylogenetic implications of Chedrinae fish,which should benefit their systematics and conservation.

摘要:
Fish is rich in essential nutrients but can remain a potential source of food poisoning. A study was, therefore, carried out with the general objective of highlighting the probable biological and chemical dangers associated with the consumption of fish and freshwater fruits from the Guéssabo river. The present study was conducted on 50 carp fish, 50 mackerel fish, 50 frogs and 50 mollusks caught in the Guéssabo River. Microorganisms were enumerated by conventional tests and heavy metals were investigated by Inductively Coupled Plasma Optical Emission Spectrometry. The enumeration showed high levels of thermotolerant Coliforms (2.5 × 104), Enterobacteriaceae (3.4 × 104), S. aureus (2.3 × 103) and Yeast/Molds (2.1 × 104), in all samples the standards were not in conformity with the required standards. High levels of Al (7230 μg/kg) and Cd (21.57 μg/kg) were observed in carp fish and these values are above the standard. In conclusion, the fish caught in the Guéssabo River could be a health risk factor for the consumer.

摘要:
诊断微生物学的最终目的是迅速,灵敏鉴定自然界的细菌.基于培养的方法耗时,而且经常会遇到不能培养的细菌.近些年,分子技术,如PCR产物杂交或测序已用于微生物的所有领域进行灵敏检测,细菌的鉴定也成为可能.但是,这些方法不能提供微生物的形态学,数量,空间分布或细胞环境.相比之下,FISH与分子遗传学结合,进行微观信息的显示.可进行自然界微小环境个体微生物细胞的显色和鉴定.1989年,Delong第一次用荧光标记的寡核苷酸检测一个微生物细胞.与放射性探针相比,荧光染色更为安全,结果更好,不需增加步骤.而且,荧光探针发射不同波长, 这样一个杂交步骤可检测到几个目的序列.过去十年,FISH以敏感,迅速,作为一个强有力的工具用于微生物学系统发育学、形态学、诊断和环境研究.本文对fish直接检测环境微生物技术进行了探讨.

摘要:
本研究目的为建立FISH(fluorescence in situ hybridization)之采样及杂交流程,以利探讨连续批分式生物膜接触滤材程序(sequencing batch biofilm reactor,SBBR)中之微生物量变化情形.探讨杂交流程时,于杂交缓冲液中添加20℅或30℅formamide,可使本研究所使用之Alc、Cory、Aci及Eub338等四支寡核酸探针之杂交时间缩短至3小时.在此条件下,杂交温度为45°C时,可得明显萤光信号.同时,纯菌菌抹片制作时先以PBS(1X)清洗3次再进行固定,可减少杂交背景,使杂交结果更为清晰.而利用直接将采样玻片插入SBBR系统滤材中采集之生物膜玻片,以Eub338探针在上述条件下进行杂交,亦呈现明显之放光反应,显示此插入式采集生物膜样品方法可行.
