基于近19年对印度Ganga—Meghna—Brahmaputra（简称GMB）平原（面积569749km^2，人口超过5亿）地下水砷污染的调查，可以确定印度Ganga—Brahmaputra平原（包括北方邦、比哈尔邦、恰尔康得邦、西孟加拉邦、阿萨姆邦）和孟加拉国普遍受到砷的污染。近期的调查研究也表明，除米佐拉姆邦外，其他各邦的地下水也受到不同程度的砷污染。至今为止．已对印度各邦和孟加拧国的175000份和50808份压把井水样进行了含砷量检测。并组织了一支包括皮肤科、神经科和妇产科医生在内的有经验的专家组，对上述地区125000人进行了临床检查，其中9％患有砷导致的皮肤病损症状。至今共采集分析了60000份生物样品。包括发样、指甲、尿样及皮肤鳞屑，其中80％的样品含砷量超过允许值，很多人由此受到砷的亚临床损害。在上述砷暴露地区．19000名儿童经过检查，近1100人患有砷导致的皮肤病损。该调查结果表明．儿童比成人更容易受到砷的毒性损害。在这种状况下．应着力解决饮水安全问题来减轻砷的苊害．

Skeletal stem and.progenitor cells(SSPCs) perform bone maintenance and.repair. With age, they prod.ce fewer osteoblasts and.more ad.pocytes lead.ng to a loss of skeletal integrity. The molecular mechanisms that und.rlie this d.trimental transformation are largely unknown. Single-cell RNA sequencing revealed.that Notch signaling becomes elevated.in SSPCs d.ring aging. To examine the role of increased.Notch activity, we d.leted.Nicastrin, an essential Notch pathway component, in SSPCs in vivo. Mid.le-aged.cond.tional knockout mice d.splayed.elevated.SSPC osteo-lineage gene expression, increased.trabecular bone mass, red.ced.bone marrow ad.posity, and.enhanced.bone repair. Thus, Notch regulates SSPC cell fate d.cisions, and.mod.rating Notch signaling ameliorates the skeletal aging phenotype, increasing bone mass even beyond.that of young mice. Finally, we id.ntified.the transcription factor Ebf3 as a d.wnstream med.ator of Notch signaling in SSPCs that is d.sregulated.with aging, highlighting it as a promising therapeutic target to rejuvenate the aged.skeleton.

Peanut （Arachis hypogaea; 2n = 4x = 40） is a nutritious food.and.a good.source of vitamins, minerals, and.healthy fats. Expansion of genetic and.genomic resources for genetic enhancement of cultivated.peanut has gained.momentum from the sequenced.genomes of the d.ploid.ancestors of cultivated.peanut. To facil- itate high-throughput genotyping of Arachis species, 20 genotypes were re-sequenced.and.genome-wid. single nucleotid. poiymorphisms （SNPs） were selected.to d.velop a large-scale SNP genotyping array. For flexibility in genotyping applications, SNPs polymorphic between tetraploid.and.d.ploid.species were includ.d.for use in cultivated.and.interspecific populations. A set of 384 accessions was used.to test the array resulting in 54 564 markers that prod.ced.high-quality polymorphic clusters between d.ploid.species, 47 116 polymorphic markers between cultivated.and.interspecific hybrid., and.15 897 polymorphic markers within A. hypogaea germplasm. An ad.itional 1193 markers were id.ntified.that illuminated.genomic re- gions exhibiting tetrasomic recombination. Furthermore, a set of elite cultivars that make up the ped.gree of US runner germplasm were genotyped.and.used.to id.ntify genomic regions that have und.rgone pos- itive selection. These observations provid. key insights on the inclusion of new genetic d.versity in culti- vated.peanut and.will inform the d.velopment of high-resolution mapping populations. d.e to its efficiency, scope, and.flexibility, the newly d.veloped.SNP array will be very useful for further genetic and.breed.ng applications in Arachis.

禽副黏病毒（APMVs）常常能从世界各地的家禽及野生鸟类中分离得到。除了禽流感,所有APMVs都归类为副黏病毒科腮腺炎病毒属。目前,腮腺炎病毒属的APMVs分为9个血清型（APMV 1~9）。新城疫病毒是禽副黏病毒1型的代表,也是各禽副黏病毒类型中特点最清楚的。对禽副黏病毒2~9（APMV2~9）的分子特性和致病性知之甚少。结果：作为了解APMV-4的分子遗传学及致病性第一步,笔者将APMV-4鸭/香港/d./75株的完整基因组进行测序,并在含胚鸡蛋中检测其致病性。APMV-4的基因组全长是15054个核苷酸（nt）的长度,并与＂六规则＂一致。基因组包含6个非重叠的基因,按3′-NP/VMF-HN-L-5′的顺序排列。基因的两侧是高度保守的转录起始和停止信号,并有长度为9至42nt的间隔序列。基因组的3′端包含了一个55nt的前导区,5′尾端区长17nt,这在禽副黏病毒科中是最短的。分析从P基因转录得到的mRNAs表明,35%的转录子通过在编辑位点插入一个非模板G残基而编辑得到V mRNA。没有信号显示有两个非模板G残基的插入,这表明在W mR-NA在受APMV-4感染的细胞产生的效率很低。F蛋白的裂解位点（d.PQR↓F）与细胞内普遍存在的风铃蛋白酶的偏好性裂解位点不一致。然而,在细胞培养中,APMV-4的生长不需要外源蛋白酶,这表明裂解并依赖于风铃位点。结果表明,对副黏病毒科的五个属病毒的核酸序列进行系统进化分析,表明APMV-4与APMVs的亲缘关系高于其它副黏病毒,进一步证实副黏病毒科腮腺炎病毒属的所有APMVs的分类。
