“Aim of this study is to verify whether there is concordance between disease’s severity, health-related quality of life (HRQoL) and disability in patients with Myasthenia gravis (MG). 102 MG patients were clustered on the

basis of HRQoL and disability scores into three groups: low disability and low HRQoL decrement (51 patients), intermediate disability and HRQoL decrement (28 patients), severe disability and high HRQoL decrement (23 patients). Cross tabulation with symmetric measures (Cramer’s V and Contingency Coefficient) was used to verify the relationships between disease severity groups, based on the Myasthenia

Gravis Foundation of America (MGFA) criteria, and obtained clusters. Results confirm a significant relationship between MG severity groups, HRQoL and disability profiles. In our opinion, HRQoL and disability instruments should be employed in clinical trials to match efficacy of treatments, measured on symptoms’ reductions only, with their effects on patients’ disability and HRQoL.”
“Novel hydrogels, physically SC75741 supplier crosslinked by hydrogen bonding of component polymers, were obtained by mixing aqueous solutions of carboxymethylchitosan (CMCS) with cellulose ethers including hydroxyethylcellulose (HEC) and methylcellulose (MC). The hydrogels were

characterized by IR, XPS, WAXD, and SEM. The swelling and controlled drug release behaviors of hydrogels were also studied. The results indicate that intermacromolecular hydrogen bonding in CMCS/HEC is stronger than that in CMCS/MC. The swelling and drug release rate of hydrogels decrease as the interaction of component polymers increases. Both the swelling and drug release from hydrogels can be controlled by component polymer ratio. The hydrogels may be potential candidates for biomedical applications.

“We report measurements of the nonlinear refractive index, n(2), and the nonlinear absorption coefficient, alpha(2), of Pb(PO3)(2)-WO3 glasses. The measurements were performed using 100 fs (17 ps) laser pulses at 800 nm (1064 nm). Positive values of n(2) similar to 10(-19) m(2)/W and negligible alpha(2) were measured. The results show that the nonlinearity is faster than 100 fs and it is observed an increase of n(2) with the increasing of the WO3 amount in the samples. The Boling, Glass, and Owyoung model, based on the semiclassical harmonic oscillator model, was used to predict the values of n(2), with basis on the values of the linear refractive index of the samples.
