D Meson Elliptic Flow in Noncentral Pb-Pb Collisions at root(S)(NN)=2.76 TeV

Abstract: Azimuthally anisotropic distributions of D-0, D+, and D*+ mesons were studied in the central rapidity region (vertical bar y vertical bar < 0.8) in Pb-Pb collisions at a center-of-mass energy root(S)(NN) = 2.76 TeV per nucleon-nucleon collision, with the ALICE detector at the LHC. The second Fourier coefficient upsilon(2) (commonly denoted elliptic flow) was measured in the centrality class 30%-50% as a function of the D meson transverse momentum p(T), in the range 2-16 GeV/c. The measured upsilon(2) of D mesons is comparable in magnitude to that of light-flavor hadrons. It is positive in the range 2 < p(T) < 6 GeV/c with 5.7 sigma significance, based on the combination of statistical and systematic uncertainties.

Soil organic carbon active fractions as early indicators for total carbon change under straw incorporation

Abstract: Changes in total organic C (CT), water-soluble organic C (CWS), microbial biomass C (CMB), C mineralization, particulate organic C (CP), labile organic C (CL), C management index (CMI), and C storage in surface Hapli-Ustic Cambisol (0–20 cm) under straw incorporation after both 2- and 10-year durations were investigated in a maize (Zea mays L.) field experiment in northeast China, in order to examine the effectiveness of these active C fractions and CMI as early indicators for total C change. The treatments included straw removal (0%S), 50% of straw incorporation (50%S), and 100% of straw incorporation (100%S). Under the straw incorporation, CT concentration and C storage did not significantly change under 2-year duration, while were significantly increased under 10-year duration. However, CMB, total C mineralization (CTM), CP, and CL, and CMI were significantly increased under the straw incorporation even after only 2-year duration, and the responses were more significant after 10-year duration. There were positive correlations between all these C indicators with each other. Our findings demonstrate that the measured active C fractions (except for CWS) and CMI can provide an early indication of change in total soil organic C induced by straw incorporation.

Effective postponement of diabetic nephropathy with enalapril in normotensive type 2 diabetic patients with microalbuminuria

Abstract: OBJECTIVE This study determines the long-term efficacy of the ACE inhibitor, enalapril, in reducing the progression of microalbuminuria to clinical albuminuria in normotensive patients with type 2 diabetes. RESEARCH DESIGN AND METHODS There were 103 normotensive type 2 diabetic patients with persistent albumin excretion rate (AER) 20–200 micrograms/min and normal renal function followed for 5 years in a prospective randomized single-blind placebo-controlled trial. AER, blood pressure, fasting plasma glucose, and HbA 1 were measured every 3–4 months and glomerular filtration rate (GFR), renal plasma flow (RPF), and urinary urea every 12 months. RESULTS In the patients treated with enalapril, AER decreased from 55 ± 33 to 20 ± 59 micrograms/min (geometric mean ± SD), whereas in the placebo group, AER increased from 53 ± 31 to 85 ± 90 micrograms/min after 5 years. Within 5 years, 7.7% (4/52) of enalapril-treated subjects and 23.5% (12/51) of placebo-treated subjects progressed to clinical albuminuria defined as AER > 200 micrograms/min and at least 34% above baseline (risk reduction = 66.7%, P P CONCLUSIONS After 5 years of therapy with enalapril, compared with placebo, normotensive subjects with type 2 diabetes experienced significantly less progression of microalbuminuria to clinical albuminuria, reduced AER, and preserved GFR.
