With the exception of mature erythrocytes, cells within the human hematopoietic system are characterized by the cell surface expression of the pan-leukocyte receptor CD45. Here, we identify a novel subset among mononuclear cord blood cells depleted of lineage commitment markers (Lin) that are devoid of CD45 expression. Surprisingly, functional examination of Lin"CD45" cells also lacking cell surface CD34 revealed they were capable of multipotential hematopoietic progenitor capacity. Co-culture with mouse embryonic limb bud cells demonstrated that Lin-CD45-CD34- cells were capable of contributing to cartilage nodules and differentiating into human chondrocytes. BMP-4, a mesodermal factor known to promote chondrogenesis, significantly augmented Lin-CD45-CD34- differentiation into chondrocytes. Moreover, unlike CD34+ human hematopoietic stem cells, Lin-CD45-CD34- cells were unable to proliferate or survive in liquid cultures, whereas single Lin-CD45-CD34- cells were able to chimerize the inner cell mass (IC

Planning for Community Relocations Due to Climate Change in Fiji

引用

International Journal of Disaster Risk Science 2015年第3期6卷 315-319页

作者： karen e.Mc Namara Helene Jacot Des Combes School of Geography Planning and Environmental ManagementThe University of Queensland Pacific Centre for environment and Sustainable Development University of the South Pacific

As a consequence of the impacts of climate change, some households and entire communities across the Pacific are making the complex and challenging decision to leave their homelands and relocate to new environments that can sustain their livelihoods. This short article charts how the residents of Vunidogoloa village in Fiji relocated in early 2014 to reduce their vulnerability to encroaching sea level and inundation events that regularly devastated the community. As a consequence of the Vunidogoloa relocation, this article also explores how the Fiji Government is planning for similar resettlement transitions, including vulnerability and adaptation assessments to develop a list of potential community relocations and the development of national relocation guidelines. This study draws from key informant interviews(n = 8) with government officials, as well as representatives from intergovernmental and local nongovernmental organizations,who are involved in the relocation issue. Given the speed at which these national, top-down initiatives are being forged and especially in light of the absence of any mention of relocation in Fiji’s 2012 climate change policy, careful and inclusive engagement across all scales and stakeholders,including communities 'earmarked' for relocation, is paramount.

Colon adenoma features and their impact on risk of future advanced adenomas and colorectal cancer

AIMTo review the evidence on the association between specific colon adenoma features and the risk of future colonic neoplasia [adenomas and colorectal cancer (CRC)]. MeTHODSWe performed a literature search using the National Library of Medicine through PubMed from 1/1/2003 to 5/30/2015. Specific Medical Subject Headings terms (colon, colon polyps, adenomatous polyps, epidemiology, natural history, growth, cancer screening, colonoscopy, CRC) were used in conjunction with subject headings/key words (surveillance, adenoma surveillance, polypectomy surveillance, and serrated adenoma). We defined non-advanced adenomas as 1-2 adenomas each 25% villous histology or high-grade dysplasia. A combined endpoint of advanced neoplasia included advanced adenomas and invasive CRC. ReSULTSOur search strategy identified 592 candidate articles of which 8 met inclusion criteria and were relevant for assessment of histology (low grade vs high grade dysplasia, villous features) and adenoma size. Six of these studies met the accepted quality indicator threshold for overall adenoma detection rate > 25% among study patients. We found 254 articles of which 7 met inclusion criteria for the evaluation of multiple adenomas. Lastly, our search revealed 222 candidate articles of which 6 met inclusion criteria for evaluation of serrated polyps. Our review found that villous features, high grade dysplasia, larger adenoma size, and having ≥ 3 adenomas at baseline are associated with an increased risk of future colonic neoplasia in some but not all studies. Serrated polyps in the proximal colon are associated with an increased risk of future colonic neoplasia, comparable to having a baseline advanced adenoma. CONCLUSIONData on adenoma features and risk of future adenomas and CRC are compelling yet modest in absolute effect size. Future research should refine this risk stratification.

Natal dispersal in a social landscape： Considering individual behavioral phenotypes and social environment in dispersal ecology

引用

Current Zoology 2015年第3期61卷 543-556页

作者： Tina W. WeY Orr SPIeGeL Pierre-Olivier MONTIGLIO karen e. MABRY Biology Department New Mexico State University Las Cruces NM 88003 USA Department of environmental Science & Policy University of California at Davis Davis CA 95616 USA

Natal dispersal, the movement of an organism from its birthplace to the site of first reproduction, is fundamental to many ecological and evolutionary processes. Mechanistically, individual dispersal decisions can depend on both individual phe- notype and environmental cues. In particular, many established evolutionary theories of dispersal highlight the importance of the social environment. More recent research in behavioral ecology has focused on the importance of individual behavioral pheno- types. We reviewed the literature on individual behavioral phenotypes and dispersal and suggest that how individual behavioral phenotypes interact with the immediate social environment experienced by individuals in influencing dispersal is still poorly un- derstood, despite growing interest. We found that very few studies had examined the interaction of individual behavioral pheno- types and social factors, and behavioral phenotypes related to social tendencies were less commonly measured than were beha- vioral phenotypes related to exploration or response to risk. Further, and unsurprisingly, studies on social behavioral phenotypes and dispersal behaviors during the transience stage of dispersal were underrepresented compared to the departure or settlement stages. Future studies in this area should aim to＂ a） make explicit links between behavioral traits and their proposed effects on dispersal decisions throughout multiple stages of dispersal, b） integrate more continuous dispersal variables, and c） consider the effects of the spatial distribution and phenotypes of conspecifics （i.e., the social landscape） encountered by individual dispersers
