The conditions for laccase immobilization on CM cellulose by bifunctional Woodward’s reagent were optimized. The catalytic Selleck DAPT properties of immobilized and native laccases were compared. The immobilized laccase appeared

an efficient catalyst for the oxidative radical polymerization of aniline on polysulfonic acid matrix at 4A degrees C. It was demonstrated that the immobilized enzyme could be repeatedly used for enzymatic synthesis of this polymer. Several spectral characteristics of the PANI/PAMPS complexes synthesized at various pH values were studied. The conductance of PANI specimens produced using immobilized laccase as a catalyst was 13 mS/cm.”
“Increased insulin resistance (IR) has been found in androgenetic alopecia in several studies. However, IR has not been investigated in alopecia areata (AA). We aimed to investigate IR in AA patients and the controls. Anthropometric and demographic data were obtained from 51 AA patients and 36 controls. We measured insulin, c-peptide and blood glucose and HOMA-IR. Demographic characteristics of the two groups were similar. AA group had higher insulin [12.5 +/- 7.01 vs. 8.3 +/- 3.9 mu IU/mL, p = 0.001], c-peptide [2.7

+/- 1.07 vs. 2.1 +/- 0.6 ng/mL, p = 0.007] and HOMA-IR levels [2.8 +/- 1.6 vs. 1.9 +/- 0.9, p = .004] than the controls. Patient and control groups were also similar regarding lipid profiles. In this study, we found increased IR in AA patients for the first time in literature. Increased inflammatory cytokines and hypothalamic-pituitary-adrenal axis activation selleck kinase inhibitor may be responsible for this finding. Further studies with larger sample sizes may give additional information for IR in AA.”
“Obesity

and associated dyslipidemia is the fastest growing health problem throughout the world. The combination of exercise and low-level laser therapy (LLLT) could be a new approach to the treatment of obesity and associated disease. In this work, the effects of LLLT associated with exercises on the lipid metabolism in regular and high-fat diet rats were verified. We used 64 rats divided in eight groups with eight rats each, designed: SC, sedentary Aurora Kinase inhibitor chow diet; SCL, sedentary chow diet laser, TC, trained chow diet; TCL, trained chow diet laser; SH, sedentary high-fat diet; SHL, sedentary high-fat diet laser; TH, trained high-fat diet; and THL, trained high-fat diet laser. The exercise used was swimming during 8 weeks/90 min daily and LLLT (GA-Al-As, 830 nm) dose of 4.7 J/point and total energy 9.4 J per animal, applied to both gastrocnemius muscles after exercise. We analyzed biochemical parameters, percentage of fat, hepatic and muscular glycogen and relative mass of tissue, and weight percentage gain. The statistical test used was ANOVA, with post hoc Tukey-Kramer for multiple analysis between groups, and the significant level was p < 0.001, p < 0.01, and p < 0.05. LLLT decreased the total cholesterol (p < 0.
