Body and transcendence in Virginia Woolf and Clarice Lispector = Corpo e transcendência em Virgínia Woolf e Clarice Lispector

Virginia Woolf and Clarice Lispector belong to quite different historical, political and cultural contexts. Beyond its antecedents and roots in European modernism, Brazilian modernism developed according to peculiar patterns and lines, cultivating, for example, more clearly political, nationalist and regionalist tendencies than happened in the British area. Molly Hite’s essay “Virginia Woolf’s Two Bodies” suggests the existence of two kinds of body represented and perhaps experienced by Virginia Woolf: “one kind was the body for others, the body cast in social roles”, the other, the “visionary body”, a second physical presence, which brings into play new perspectives on the female modernist body and new strategies of political and aesthetic representation. It is this “visionary body”, that, in many moments, intersects with transcendence. These two kinds of body are also present in Clarice Lispector’s work, structured, of course, around other complexities and gradations, explained by a different temporal context, but still touching common seminal questions. In Lispector, it is through the body cast in social roles that you reach the “visionary body” and transcendence. The movement is not a flight, as in Woolf, on the contrary it is a necessity, a condition to get to the essence.

Influence of the molecular weight in mechanical properties and degradation kinetics of chitosan inverted colloidal crystals

Tissue engineering arises from the need to regenerate organs and tissues, requiring the development of scaffolds, which can provide an optimum environment for tissue growth. In this work, chitosan with different molecular weights was used to develop biodegradable 3D inverted colloidal crystals (ICC) structures for bone regeneration, exhibiting uniform pore size and interconnected network. Moreover, in vitro tests were conducted by studying the influence of the molecular weight in the degradation kinetics and mechanical properties. The production of ICC included four major stages: fabrication of microspheres; assembly into a cohesive structure, polymeric solution infiltration and microsphere removal. Chitosan’s degree of deacetylation was determined by infrared spectroscopy and molecular weight was obtained via capillary viscometry. In order to understand the effect of the molecular weight in ICC structures, the mass loss and mechanical properties were analyzed after degradation with lysozyme. Structure morphology observation before and after degradation was performed by scanning electron microscopy. Cellular adhesion and proliferation tests were carried out to evaluate ICC in vitro response. Overall, medium molecular weight ICC revealed the best balance in terms of mechanical properties, degradation rate, morphology and biological behaviour.
