11.1.11), catalase (CAT: EC 1.11.1.6) and peroxidase (POD: EC 1.11.1.7)] and a reduction in endogenous H2O2 levels and root vitality. Although grass pea seeds absorbed exogenous H2O2 during seed germination, DAB staining of paraffin sections revealed that exogenous H2O2 only entered the root epidermis and not inner tissues. These data indicated that exogenously applied H2O2 could lead to a reversible loss of the root gravitropic response and a horizontal curvature in primary roots during radicle

emergence of the seedling. (C) 2012 Elsevier Masson SAS. All rights reserved.”
“Ninety-one consecutive systemic lupus erythematosus (SLE) patients (American College of Rheumatology criteria) with a history of cutaneous vasculitis were compared to 163 SLE controls without this clinical manifestation from July to December 2007 in order to determine the possible clinical and

serological association of this manifestation. this website Data were obtained in an ongoing electronic database protocol and autoantibodies to anti-double-stranded DNA, anti-Sm, anti-RNP, anti-Ro/SS-A, anti-La/SS-B, and anticardiolipin and ribosomal P protein antibody (anti-P) were detected by standard techniques. Exclusion criteria were the presence of anti-phospholipid syndrome or antibodies, Sjogren syndrome, and a history of thrombosis. The mean age (38.5 +/- 11.5 vs. 37.8 +/- 11.6 years, p = 0.635), disease duration (12.5 +/- 7.8 vs. 11.8 +/- 7.9 years, p = 0.501), and frequency of white race (71.4% vs. 70.5%, p = 0.872) and female sex (96.8% vs. 93.7%, p = 0.272) were comparable in both groups. The SHP099 vasculitis learn more group had a higher frequency of malar rash (97.9% vs. 87.4%, p = 0.004), photosensitivity (91.4% vs. 81.6%, p = 0.030), and Raynaud phenomenon (RP; 27.7% vs. 7.5%, p < 0.001), whereas all other clinical manifestation including renal and central nervous system involvements were similar to the control group. Laboratorial

data revealed that only anti-P (35.1% vs. 12.1%, p < 0.001) was more frequent in patients with vasculitis. In a multivariate logistic regression model, cutaneous vasculitis was associated to the presence of RP (OR = 3.70; 95% confidence interval [CI] = 1.73-8.00) and anti-P (OR = 3.42; 95% CI = 1.76-6.66). In summary, SLE cutaneous vasculitis characterizes a subgroup of patients with more RP and anti-P antibodies but not accompanied by a higher frequency of renal and central nervous system involvements.”
“The electronic structure of the poly(3-hexylthiophene):indene-C-60 bisadduct (P3HT:ICBA) blend is investigated with direct and inverse photoemission spectroscopy. The energy gap between the lowest unoccupied molecular orbital (LUMO) of ICBA and the highest occupied molecular orbital (HOMO) of P3HT, which is central to the performance of photovoltaic cells made with this blend, is found equal to 1.68 eV.
