Over the course of the past 35 years,assisted reproductive technologies(ARTs)have been increasingly used worldwide,while debates on their safety have been generated.Birth defects and imprinting disorders were reported in previous research.Thus,the psychological development of children born following ARTs has become a major concern nowadays.This review gives a systematic view of psychological well-being of children conceived by different types of ART,including in vitro fertilization,intracytoplasmic sperm injection(ICSI),preimplantation genetic diagnosis/screening,and in vitro maturation.The previous studies are analyzed in three sections:(1)cognitive,motor,and language developments,(2)behavior problems and socio-emotional development,and(3)parent-child relationship.We conclude that although the majority of the studies on cognitive,motor,and language developments reported comparable achievements in the ART group vs.the naturally conceived group,lower intelligence quotient(IQ)scores,worse visual-motor ability or locomotor development,and delayed receptive language competence were found in the ART group.The results on the socio-emotional development were reassuring.As for the behavior problems,a higher prevalence of behavior problems existed in ART children;moreover,ICSI children were found to be at a higher risk of autism than the general population.Meanwhile,ART parents tended to have positive parental attitudes and be more protective of their children.Some suggestions for further research are also given in this review.

Animal Reproduction technologies-FuturePerspectives

引用

Journal of Agricultural Science and Technology(A) 2016年第5期6卷 301-313页

作者： Jane Morrell Patrice Humblot Department of Clinical Sciences Swedish University of Agricultural Sciences (SLU) Box 7054 SE-75007 Uppsala Sweden

Reproductive biotechnologies, such as artificial insemination, sperm selection and embryo technologies, offer possibilitiesfor animal producers to increase reproductive efficiency. There have been many significant developments in reproductivebiotechnologies over the last few decades, e.g., in sperm handling and preservation, in vitro embryo production and preservation,sexing and cloning. This review discusses some of the key changes that have occurred and explores their potential for increasing thereproductive efficiency of domestic animals in the future. As a consequence, they also offer opportunities to facilitate or accelerategenetic selection. If properly used, they may contribute to increase the sustainability of animal production. The role of epigenetics ininfluencing phenotype is also considered.

A Catastrophe Model to Assess Soil Restoration Under Ecological Restoration in the Red Soil Hilly Region of China

引用

Pedosphere 2017年第4期27卷 778-787页

作者： CHEN Zhiqiang CHEN Zhibiao BAI Liyue ZENG Yuee School of Geographical Sciences Fujian Normal UniversityFuzhou 350007China State Key Laboratory of Humid Subtropical Mountain Ecology Fuzhou 350007China Institute of Geography Sciences Fujian Normal UniversityFuzhou 350007China Rural Work Research Center of Fujian Agriculture Department Fuzhou 350007China

Current methods that utilize simple data or models to evaluate soil restoration under ecological restoration are not sufficiently rigorous.Soil restoration under ecological restoration measures was evaluated in the red soil hilly region of China by applying the catastrophe model.Among 89 soil sites selected,26(29.21%) were in the middle lobe,10(11.24%) in the upper lobe,and 53(70.79%)in the lower lobe of the process surface in the Cusp catastrophe model.The catastrophic direction of the 26 unstable soil sites was to the upper lobe of the process surface according to vegetation cover change and fieldwork.There was a significant negative correlation of the variation in bifurcation set(? value) with vegetation cover increase,and a higher vegetation cover increase was related to higher unstable probability.The four ecological restoration measures were listed in the order:low-quality forest improvement(LQFI)>arbor-bush-herb mixed plantation(ABHMP)>orchard improvement(OI)>closing measures(CM) according to the proportions of unstable soil sites,which were all higher than no restoration measure,while they were in the order:LQFIABHMPOICM according to their ? values,which were all lower than those of no restoration measure.Farmers' assessment of soil restoration under the four ecological restoration measures was in accordance with the proportions of unstable soil sites and inversely proportional to the? value.Therefore,farmers' assessment can prove the evaluation of soil restoration under ecological restoration measures based on catastrophe model.
