A function for novel uncoupling proteins: antioxidant defense of mitochondrial matrix by translocating fatty acid peroxides from the inner to the outer membrane leaflet

Abstract: It is hypothesized that mitochondrial uncoupling proteins operate as carriers of fatty acid peroxide anions. This is assumed to result in electrophoretic extrusion of such anions from the inner to the outer leaflet of the inner mitochondrial membrane, being driven by membrane potential (mitochondrial interior negative). In this way, the inner leaflet is ridded of fatty acid peroxides that otherwise can form very aggressive oxidants damaging mitochondrial DNA, aconitase, and other mitochondrial matrix-localized components of vital importance. The steady-state concentration the fatty acid peroxides is known to be low. This explains why UCP2, 3, 4, and 5 are present in small amounts usually insufficient to make a large contribution to the H+ conductance of the mitochondrial membrane.—Goglia, F., Skulachev, V. P.

Search for gravitational waves from low mass compact binary coalescence in LIGO's sixth science run and Virgo's science runs 2 and 3

Abstract: We report on a search for gravitational waves from coalescing compact binaries using LIGO and Virgo observations between July 7, 2009, and October 20, 2010. We searched for signals from binaries with total mass between 2 and 25M(circle dot); this includes binary neutron stars, binary black holes, and binaries consisting of a black hole and neutron star. The detectors were sensitive to systems up to 40 Mpc distant for binary neutron stars, and further for higher mass systems. No gravitational-wave signals were detected. We report upper limits on the rate of compact binary coalescence as a function of total mass, including the results from previous LIGO and Virgo observations. The cumulative 90% confidence rate upper limits of the binary coalescence of binary neutron star, neutron star-black hole, and binary black hole systems are 1.3 x 10(-4), 3.1 x 10(-5), and 6.4 x 10(-6) Mpc(-3) yr(-1), respectively. These upper limits are up to a factor 1.4 lower than previously derived limits. We also report on results from a blind injection challenge.

Critical evaluation of stability constants of phosphonic acids (IUPAC Technical Report)

Abstract: Available experimental data on stability constants of proton and metal complexes for 10 phosphonic acids [methylphosphonic acid, 1-hydroxyethane-1,1-diylbisphosphonic acid, dichloromethylenebisphosphonic acid, aminomethanephosphonic acid, N-(phosphonomethyl)glycine, imino-N,N-bis(methylenephosphonic acid), N-methylamino-N,N-bis(methylenephosphonic acid), nitrilotris(methylenephosphonic acid), 1,2-diaminoethane-N,N,N',N'-tetrakis-(methylenephosphonic acid), and diethylenetriamine-N,N,N',N",N"-pentakis-(methylenephosphonic acid)], published in 1950-1997, have been critically evaluated. For the latter phosphonate, all the data are rejected, as well as protonation constants [HL]/[H][L] for three other ligands. Higher-quality data are selected and presented as "Recommended" and "Provisional".
