Novel edible films made of polysaccharide from Anarcadium occidentale L.

Edible and/or biodegradable films have been evaluated in applications such as transportation of active materials, selective barrier to gases and solutes, and as an alternative to synthetic non-renewable packaging materials. This work aimed at producing and evaluating the mechanical characteristics of films of polysaccharide from the Anarcadium ocidentale L. tree gum (POLICAJU), in view to their application as protection to increase the shelf life of fruits and vegetables and as cutaneous dressing. Films with different POLICAJU concentrations (1% - 3% w/v) were cast using different plasticizers (sorbitol, glycerol and polyethylene glycol), at different concentrations (0.02 to 0.5% g/g of POLICAJU), in the presence and in the absence of Tween 80 as surfactant (0.05% w/w). The solution of 3.0% (w/v) of POLICAJU, 0.4% (w/w) sorbitol and 0.05% (w/w) Tween 80 was the one featuring a better flexibility and mechanical resistance (to traction). This has been determined with an INSTRON (model 4505) machine, with a load cell of 2.5 N. The film, of 0.07 mm thickness, stretched for a length 62 % higher than its original length, while resisting to a force of 0.2 N. These results suggest that this material has enough resistance to be used for the intended applications

Cryotolerance and pregnancy rates after exposure of bovine in vitro-produced embryos to forskolin and linoleic acid before vitrification.

The objective of the present study was to evaluate the effects of supplementation of in vitro culture (IVC) medium with drugs that stimulates the lipolysis (Forskolin: Forsk) and inhibit the lipogenesis (Linoleic Acid LA) on the intracytoplasmic lipid content and cryotolerance of bovine embryos (Experiment 1), as well as to evaluate the effect of treatment of embryos with Forsk on the pregnancy rates after transfer to synchronized recipients (Experiment 2).Proceedings of the 30th Annual Meeting of the Brazilian Embryo Technology Society (SBTE); Foz do Iguaçu, PR, Brazil, August 25th to 27th, 2016, and 32nd Meeting of the European Embryo Transfer Association (AETE); Barcelona, Spain, September 9th and 10th, 2016.

Healing activity induced by glucose/mannose lectins in mice

This work aimed the use of glucose/mannose lectins (Cramoll, EmaL and Con A) in the treatment of cutaneous wounds in mice.Surgical wounds were treated daily with the lectins and parameters such as edema, hyperemia, scab, granulation and scar tissues as well as contraction of wounds were analyzed. The lectin wounds showed higher edema and arrival of more polimorphonuclear cells at the site of lesions when compared with control group (0.15 M NaCl). Granulation tissue and collagen fiber deposition were observed with higher intensity in all lectin treated wounds promoting excellent closing and repair of lesions in less time than other groups. Results showed that Cramoll was more effective in the repair of experimental lesions in mice;however, the glucose/mannose lectins can be used as future cicatricial compounds
