“Tubular scaffolds demonstrated to be able to reconnect the proximal and distal stumps of transected peripheral nerves and induce regeneration of the lost nerve trunk. learn more Recently, a spinning technique has been developed, able to produce tubular collagen-based scaffolds characterized by a radially patterned microporosity. The technique is based on the centrifugal sedimentation of collagen
taking place when I cylinder, containing, all aqueous collagen suspension, is rotated rapidly around its axis. In
this work, the centrifugation process was modeled by means of the Lamm differential equation for collagen Concentration, with the assumption that sedimentation and diffusion coefficients Selleck PXD101 were dependent on the local concentration, according to appropriate scaling laws. With such assumptions, the model was able to predict the actual tube formation and its inner radius, ill good agreement with the experiment results. The possibility to predict the final scaffold inner diameter as a function of the processing parameters has a fundamental importance for the set LIP of a precise fabrication method, which does not make use of arty complex mold. This would significantly reduce the production complexity and the extent of scaffold manipulation during production, resulting in a cleaner production process and safety, of the device.

“Background: Obesity is related to asthma, but factors influencing this relation have not been
clearly defined.
Objective: This study was designed to assess the role of eating behaviors and weight concerns in the association between obesity and asthma.
Design: A population-based sample of 11,710 adolescents, recruited from 186 secondary schools of 8 educational districts in France, completed a self-administered standardized questionnaire including DSM IV (Diagnostic and Statistical Manual of Mental Disorders) questions on eating disorders.
Results: Obesity (body mass index >= 95th percentile according to age and sex) was associated with asthma in girls (odds ratio: 1.48; 95% CI: 1.05, MLN4924 2.08) but not in boys (odds ratio: 1.07; 95% CI: 0.75, 1.54). Both obese and asthmatic adolescents were more likely to have abnormal eating behaviors and weight concerns (P < 0.05). In an adjusted polytomous logistic model with 4 categories based on the presence and/or the absence of asthma and obesity as the dependent variable, the odds ratio for weight concerns increased from a minimum value for asthmatic nonobese adolescents (odds ratio: < 1.5; P < 0.03) to a maximum value for asthmatic obese adolescents (odds ratio:> 6.3; P < 0.
