    Description: Alterations in intestinal microbiota composition are associated with several chronic conditions, including obesity and inflammatory diseases. The microbiota of older people displays greater inter-individual variation than that of younger adults. Here we show that the faecal microbiota composition from 178 elderly subjects formed groups, correlating with residence location in the community, day-hospital, rehabilitation or in long-term residential care. However, clustering of subjects by diet separated them by the same residence location and microbiota groupings. The separation of microbiota composition significantly correlated with measures of frailty, co-morbidity, nutritional status, markers of inflammation and with metabolites in faecal water. The individual microbiota of people in long-stay care was significantly less diverse than that of community dwellers. Loss of community-associated microbiota correlated with increased frailty. Collectively, the data support a relationship between diet, microbiota and health status, and indicate a role for diet-driven microbiota alterations in varying rates of health decline upon ageing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Claesson, Marcus J -- Jeffery, Ian B -- Conde, Susana -- Power, Susan E -- O'Connor, Eibhlis M -- Cusack, Siobhan -- Harris, Hugh M B -- Coakley, Mairead -- Lakshminarayanan, Bhuvaneswari -- O'Sullivan, Orla -- Fitzgerald, Gerald F -- Deane, Jennifer -- O'Connor, Michael -- Harnedy, Norma -- O'Connor, Kieran -- O'Mahony, Denis -- van Sinderen, Douwe -- Wallace, Martina -- Brennan, Lorraine -- Stanton, Catherine -- Marchesi, Julian R -- Fitzgerald, Anthony P -- Shanahan, Fergus -- Hill, Colin -- Ross, R Paul -- O'Toole, Paul W -- England -- Nature. 2012 Aug 9;488(7410):178-84. doi: 10.1038/nature11319.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University College Cork, Ireland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22797518" target="_blank"〉PubMed〈/a〉

    Description: Obtaining high-resolution information from a complex system, while maintaining the global perspective needed to understand system function, represents a key challenge in biology. Here we address this challenge with a method (termed CLARITY) for the transformation of intact tissue into a nanoporous hydrogel-hybridized form (crosslinked to a three-dimensional network of hydrophilic polymers) that is fully assembled but optically transparent and macromolecule-permeable. Using mouse brains, we show intact-tissue imaging of long-range projections, local circuit wiring, cellular relationships, subcellular structures, protein complexes, nucleic acids and neurotransmitters. CLARITY also enables intact-tissue in situ hybridization, immunohistochemistry with multiple rounds of staining and de-staining in non-sectioned tissue, and antibody labelling throughout the intact adult mouse brain. Finally, we show that CLARITY enables fine structural analysis of clinical samples, including non-sectioned human tissue from a neuropsychiatric-disease setting, establishing a path for the transmutation of human tissue into a stable, intact and accessible form suitable for probing structural and molecular underpinnings of physiological function and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4092167/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4092167/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chung, Kwanghun -- Wallace, Jenelle -- Kim, Sung-Yon -- Kalyanasundaram, Sandhiya -- Andalman, Aaron S -- Davidson, Thomas J -- Mirzabekov, Julie J -- Zalocusky, Kelly A -- Mattis, Joanna -- Denisin, Aleksandra K -- Pak, Sally -- Bernstein, Hannah -- Ramakrishnan, Charu -- Grosenick, Logan -- Gradinaru, Viviana -- Deisseroth, Karl -- DP1 OD000616/OD/NIH HHS/ -- R01 DA020794/DA/NIDA NIH HHS/ -- R01 MH099647/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2013 May 16;497(7449):332-7. doi: 10.1038/nature12107.
