    Description: Copper influences the pathogenesis of prion disease, but whether it is beneficial or detrimental remains controversial. Copper homeostasis is also essential for normal physiology, as highlighted by the spectrum of diseases caused by disruption of the copper transporting enzymes ATP7A and ATP7B. Here, by using a forward genetics approach in...

    Description: We use the observed anisotropic clustering of galaxies in the Baryon Oscillation Spectroscopic Survey Data Release 11 CMASS sample to measure the linear growth rate of structure, the Hubble expansion rate and the comoving distance scale. Our sample covers 8498 deg 2 and encloses an effective volume of 6 Gpc 3 at an effective redshift of $\bar{z} = 0.57$ . We find f 8  = 0.441 ± 0.044, H  = 93.1 ± 3.0 km s –1 Mpc –1 and D A  = 1380 ± 23 Mpc when fitting the growth and expansion rate simultaneously. When we fix the background expansion to the one predicted by spatially flat cold dark matter (CDM) model in agreement with recent Planck results, we find f 8  = 0.447 ± 0.028 (6 per cent accuracy). While our measurements are generally consistent with the predictions of CDM and general relativity, they mildly favour models in which the strength of gravitational interactions is weaker than what is predicted by general relativity. Combining our measurements with recent cosmic microwave background data results in tight constraints on basic cosmological parameters and deviations from the standard cosmological model. Separately varying these parameters, we find w  = –0.983 ± 0.075 (8 per cent accuracy) and  = 0.69 ± 0.11 (16 per cent accuracy) for the effective equation of state of dark energy and the growth rate index, respectively. Both constraints are in good agreement with the standard model values of w  = –1 and  = 0.554.

    Description: We explore the cosmological implications of the angle-averaged correlation function, ( s ), and the clustering wedges, ( s ) and || ( s ), of the LOWZ and CMASS galaxy samples from Data Releases 10 and 11 of the Sloan Digital Sky Survey III (SDSS-III) Baryon Oscillation Spectroscopic Survey. Our results show no significant evidence for a deviation from the standard cold dark matter model. The combination of the information from our clustering measurements with recent data from the cosmic microwave background is sufficient to constrain the curvature of the Universe to k  = 0.0010 ± 0.0029, the total neutrino mass to m  〈 0.23 eV (95 per cent confidence level), the effective number of relativistic species to N eff  = 3.31 ± 0.27 and the dark energy equation of state to w DE  = –1.051 ± 0.076. These limits are further improved by adding information from Type Ia supernovae and baryon acoustic oscillations from other samples. In particular, this data set combination is completely consistent with a time-independent dark energy equation of state, in which case we find w DE  = –1.024 ± 0.052. We explore the constraints on the growth rate of cosmic structures assuming f ( z ) =  m ( z ) and obtain  = 0.69 ± 0.15, consistent with the predictions of general relativity of  = 0.55.

    Description: Gaucher disease is characterized by the accumulation of glucocerebroside, leading to enlargement of the liver and spleen and lesions in the bones. It is caused by an inherited deficiency of the enzyme glucocerebrosidase. Many mutations exist, but four of these account for over 97% of the mutations in Ashkenazi Jews, the population group in which Gaucher disease is the most common. Although there is a strong relation between the mutations and disease manifestations, genetic counseling is made difficult by the fact that within each genotype there is considerable variability in the severity of the disease. Intravenous infusion of glucocerebrosidase is an effective treatment, but the availability of enzyme replacement therapy is limited by its high cost. Marrow transplantation is also effective in treating the disease, but is rarely performed because of the risks involved. In the future gene transfer may become the treatment of choice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beutler, E -- DK36639/DK/NIDDK NIH HHS/ -- RR00833/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1992 May 8;256(5058):794-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Experimental Medicine, Scripps Research Institute, La Jolla, CA 92037.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1589760" target="_blank"〉PubMed〈/a〉

    Description: Hepcidin, a liver-derived protein that restricts enteric iron absorption, is the key regulator of body iron content. Several proteins induce expression of the hepcidin-encoding gene Hamp in response to infection or high levels of iron. However, mechanism(s) of Hamp suppression during iron depletion are poorly understood. We describe mask: a recessive, chemically induced mutant mouse phenotype, characterized by progressive loss of body (but not facial) hair and microcytic anemia. The mask phenotype results from reduced absorption of dietary iron caused by high levels of hepcidin and is due to a splicing defect in the transmembrane serine protease 6 gene Tmprss6. Overexpression of normal TMPRSS6 protein suppresses activation of the Hamp promoter, and the TMPRSS6 cytoplasmic domain mediates Hamp suppression via proximal promoter element(s). TMPRSS6 is an essential component of a pathway that detects iron deficiency and blocks Hamp transcription, permitting enhanced dietary iron absorption.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2430097/" 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/PMC2430097/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Du, Xin -- She, Ellen -- Gelbart, Terri -- Truksa, Jaroslav -- Lee, Pauline -- Xia, Yu -- Khovananth, Kevin -- Mudd, Suzanne -- Mann, Navjiwan -- Moresco, Eva Marie Y -- Beutler, Ernest -- Beutler, Bruce -- AI054523/AI/NIAID NIH HHS/ -- DK53505-09/DK/NIDDK NIH HHS/ -- R01 DK053505-09/DK/NIDDK NIH HHS/ -- U54 AI054523/AI/NIAID NIH HHS/ -- U54 AI054523-019005/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2008 May 23;320(5879):1088-92. doi: 10.1126/science.1157121.

    Notes: Abstract Gaucher disease is the most common glycolipid storage disease. Type I, the most common form of the disease, is characterised by enlargement of the liver, and spleen and bone lesions. In the rare type II and type III forms of the disorder, central nervous system involvement is present as well. The disease results from a deficiency of the lysosomal enzyme glucocerebrosidase, which is needed for the enzymatic degradation of complex lipids, globosides and gangliosides. In the absence of sufficient glucocerebrosidase activity, the catabolic product glucocerebroside accumulates.
