Daylighting: appraisal at the early design stages

For a building design team concerned with the quality of the internal environment of buildings the percentage area of glazing on a building facade is one of the most useful criteria for judging the building envelope as a modifier of climate at early design stages since it is at the window that the various environmental parameters (heat, light and sound) remain only minimally modified. The percentage area of glazing can be used to relate the numerous and often conflicting functions of the window such as the provision of daylight, summer time teperatures, sound insulation, energy efficiency and view satisfaction

Isolation of Progenitors that Exhibit Myogenic/Osteogenic Bipotency In Vitro by Fluorescence-Activated Cell Sorting from Human Fetal Muscle

Summary Fluorescence-activated cell sorting (FACS) strategies to purify distinct cell types from the pool of fetal human myofiber-associated (hMFA) cells were developed. We demonstrate that cells expressing the satellite cell marker PAX7 are highly enriched within the subset of CD45−CD11b−GlyA−CD31−CD34−CD56intITGA7hi hMFA cells. These CD45−CD11b−GlyA−CD31−CD34−CD56intITGA7hi cells lack adipogenic capacity but exhibit robust, bipotent myogenic and osteogenic activity in vitro and engraft myofibers when transplanted into mouse muscle. In contrast, CD45−CD11b−GlyA−CD31−CD34+ fetal hMFA cells represent stromal constituents of muscle that do not express PAX7, lack myogenic function, and exhibit adipogenic and osteogenic capacity in vitro. Adult muscle likewise contains PAX7+ CD45−CD11b−GlyA−CD31−CD34−CD56intITGA7hi hMFA cells with in vitro myogenic and osteogenic activity, although these cells are present at lower frequency in comparison to their fetal counterparts. The ability to directly isolate functionally distinct progenitor cells from human muscle will enable novel insights into muscle lineage specification and homeostasis

Disability and Health in South Carolina

The BRFSS is a state based cross-sectional telephone survey conducted to assess health behaviors and risk factor prevalence within the US, its states and its territories. People with disability are identified as a possible health disparity group. To reduce these disparities, it is important to understand the health status of those with and without disabilities. This report describes various critical health indicators for South Carolina adults with and without disabilities

Clonal analyses and gene profiling identify genetic biomarkers of human brown and white preadipocyte thermogenic potential

Targeting brown adipose tissue (BAT) content or activity has therapeutic potential for treating obesity and the metabolic syndrome by increasing energy expenditure. Both inter- and intra-individual differences contribute to heterogeneity in human BAT and potentially to differential thermogenic capacity in human populations. Here, we demonstrated the generated clones of brown and white preadipocytes from human neck fat of four individuals and characterized their adipogenic differentiation and thermogenic function. Combining an uncoupling protein 1(UCP1) reporter system and expression profiling, we defined novel sets of gene signatures in human preadipocytes that could predict the thermogenic potential of the cells once they were maturated in culture. Knocking out the positive UCP1 regulators identified by this approach, PREX1 and EDNRB in brown preadipocytes using CRISPR/Cas9 markedly abolished the high level of UCP1 in brown adipocytes differentiated from the preadipocytes. Finally, we were able to prospectively isolate adipose progenitors with great thermogenic potential using cell surface marker CD29. These data provide new insights into the cellular heterogeneity in human fat and offer the identification of possible biomarkers of thermogenically competent preadipocytes
