Texto completoLa lombalgie chronique est la manifestation clinique de la dégénération des disques intervertébraux. La nucleoplastie est une nouvelle technique destinée à traiter la dégénération du disque dans ses premières phases. Le principe consiste à injecter un polymère sous forme liquide, l'hydrogel poly(vinyl alcool), dans le nucléus pulposus, et de le laisser durcir in situ. Deux types d'hydrogels poly(vinyl alcool) ont été étudiés ici pour cette application. La capacité à s'étendre, la rigidité, la pression requise pour l'extrusion et la vitesse de durcissement en fonction de la température ont ainsi été caractérisés pour chacun des deux polymères. Les hydrogels ont des caractéristiques semblables au nucléus pulposus naturel : ils s'étendent de 10 à 20 % en poids et, immergés dans du tampon phosphate salin, maintiennent une rigidité de 1-2.5 MPa pendant 8 semaines. La pression d'extrusion varie significativement avec la température de l'hydrogel et le temps écoulé. La vitesse de durcissement du premier hydrogel était lente, alors que le second atteignait 70 % de sa rigidité finale en moins de 72 heurs. Cette seconde formulation semble plus prometteuse pour des applications cliniques.

Texto completoIn papermaking, the addition of filler can be detrimental to the properties of the resulting paper hence the use of additives that enhance paper properties are of paramount importance. Syndiotacticity rich poly(vinyl alcohol) (PVA) microfibrils were prepared for use as filler retention aids. They were prepared via in situ fibrillation during the saponification of high molecular weight poly(vinyl pivalate). The resulting fibers had high thermal stability and crystalline melting temperature. They were not fully soluble in water even at 100 oC. In order to make them less water resistant the syndiotacticity of the PVA microfibrils was varied by copolymerizing vinyl pivalate with vinyl acetate and saponifying the resultant copolymer. It was observed that changes in syndiotacticity had a significant effect on the crystallinity, morphology and thermal properties of the resultant PVA. The surfaces of the fibers were modified by first crosslinking using glyoxal (a dialdehyde), and then attaching cationic and anionic groups by grafting and by carboxymethylation. Crosslinking prior to modification was beneficial in minimizing the solubility of the fibers in the aqueous media in which they were modified. Heterogeneous modification techniques were employed so that fiber properties could be preserved. Carboxymethylation was carried out using the two step Williamson’s ether synthesis. The first step involves the formation of a highly reactive alkoxide by the reaction of PVA with a strong base and the second its etherification using a functional alkyl halide. Poly(methacryloyloxy ethyl trimethyl ammonium chloride) and poly(acrylic acid) were grafted from the PVA microfibrils using the KPS/Na2S2O3 redox initiation system. Grafting was confirmed by FTIR and NMR spectroscopy. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were carried out on both modified and unmodified PVA microfibrils. The results showed that crosslinking resulted in an enhancement of the thermal properties of the microfibrils. A decline in the onset temperature for thermal degradation and crystalline melting temperature were observed, and were attributed to the modification of the PVA microfibrils.

Resumo: Stents são malhas metálicas expansíveis usadas em procedimentos de angioplastia, para a desobstrução das artérias coronárias. Atualmente há um grande interesse na obtenção de stents revestidos com matrizes poliméricas eluidoras de drogas que impeçam a reoclusão da artéria (reestenose). S-nitrosotióis doadores de óxido nítrico (NO) como a S-nitrosoglutationa (GSNO) possuem potencial para a inibição da reestenose. Neste trabalho, placas metálicas e stents foram revestidos com filmes de PVA contendo GSNO (107 µmol/g) através da imersão em soluções de PVA/GSNO com concentrações de PVA de 0,5 a 10,0% m/v. Filmes de PVA/GSNO foram submetidos a ciclos de congelamento/descongelamento (C/D), e analisados em relação ao seu grau de cristalinidade, dissolução, intumescimento, morfologia e propriedades de difusão e eluição da GSNO. Análises por DSC e difração de raios X, mostraram que o grau de cristalinidade do PVA aumenta com o número de ciclos de C/D, e com a secagem por sublimação do filme congelado. O aumento da cristalinidade se reflete em uma diminuição da velocidade de eluição da GSNO para a fase aquosa e da velocidade de dissolução e grau de intumecimento da matriz. Os coeficientes de difusão (D) da GSNO através de filmes de PVA foram medidos utilizando-se uma cela tipo Franz com monitoramento espectrofotométrico. Verificou-se que os valores de D são menores nos filmes secos por sublimação e submetidos a um ciclo de C/D. Este resultado foi atribuído ao aumento da densificação da fase amorfa, obtido na secagem por sublimação. Os filmes secos por esta técnica, apresentaram uma estrutura tridimensional esponjosa constituída por filamentos interligados, revelada por microscopia eletrônica de varredura (MEV). Estimou-se que stents revestidos com PVA/GSNO, a partir de soluções de PVA 0,5 % (m/v) esterilizados com óxido de etileno a 45-55°C podem liberar cerca de 30 µmoles/g de PVA para a parede arterial e levaram à obtenção de revestimentos sem filmes entre as hastes metálicas
Abstract: Stents are expansible wire mesh tubes used in angioplasty procedures in order to widening the luminal diameter of the coronary arteries. There is currently a great interest in the development of stents coated with drug-eluting polymeric matrices, which are able to prevent future closure of artery (restenosis). S-nitrosothiols which are nitric oxide (NO) donors, like S-nitrosoglutathione (GSNO) have potential to inhibit restenosis. In the present work, metallic plates and stents were coated with GSNO (107 µmol/g)- containing PVA films through their immersion in PVA/GSNO solutions with PVA concentration ranging from 0.5 to 10.0% wt/v. PVA/GSNO films were submitted to freezing/thawing cycles (F/T) and analyzed concerning their crystallinity dissolution, swelling, morphology and GSNO diffusion and elution properties. DSC and X Ray diffraction analysis have shown that the PVA crystallinity degree increases with the increase in the number of F/T cycles, and with the drying of the frozen film by sublimation. The increase in cristallinity was reflected in a decrease of the rate of GSNO elution to the aqueous phase, dissolution rate and swelling degree of the matrix. The diffusion coefficients of GSNO through PVA films were measured using a Franz-like cell with spectrophotometric monitoring. It was verified that D values are lower in the films dried by sublimation and submitted to one FT cycle. This result was attributed to the increase in the densification of the amorphous phase obtained in the drying by sublimation. The films dried by this technique, displayed a spongelike three-dimensional structure made by interconnecting filaments, revealed by scanning electron microscopy (SEM). Stents coated with PVA/GSNO, from solution of PVA 0.5 % (wt/v) have avoided the formation of films between the wires of the stent mesh. It was estimated that these stents are able to release ca. 30 µmols/g of PVA to the arterial wall after sterilization with ethylene oxide at 45-55 °C
