摘要：Autism is a complex neuropsychiatric disorder of developmental origin, where multiple genetic and environmental factors likely interact resulting in a clinical continuum between "affected" and "unaffected" individuals in the general population. During the last two decades, relevant progress has been made in identifying chromosomal regions and genes in linkage or association with autism, but no single gene has emerged as a major cause of disease in a large number of patients. The purpose of this paper is to discuss specific methodological issues and experimental strategies in autism genetic research, based on fourteen years of experience in patient recruitment and association studies of autism spectrum disorder in Italy.

摘要：Problem: There is a need to collect the many and varied data on AD/HD (Attention deficit hyper-activity disorder) into a meaningful overview. Method: Based on peer reviewed and published data as well as own research we try to make sense of the physiological mechanisms resulting in the relevant symptoms. Conclusion: AD/HD clearly has a genetic disposition, but as with many other genetic syndromes, the resulting proteomics must be stressed to become manifest as disease/ disorder. A common trait in the different etiologies is lower arousal.

摘要：中国农业科学院中国水稻研究所超级稻种质创新团队与中国科学院遗传与发育生物研究所等单位最新合作研究发现,水稻染色体拷贝数变异可调控水稻的粒长和品质,为水稻粒形的分子设计和高产优质水稻新品种培育奠定了基础。7月6日,国际著名学术期刊《自然-遗传学（Nature genetics）》在线发表了这一研究成果。水稻粒形是衡量稻米外观品质的主要指标,同时也是影响水稻产量性状的重要因素之一,因此成为重要的水稻育种农艺性状。我国的水稻分籼、
