RESUMO
Coatings are defined as edible products which form a thin layer on the food, and are characterized by it constitute a semipermeable barrier to gases and water vapor retarding food spoilage, improve the mechanical properties, help maintain the structural integrity of the product wrapping, to retain volatile compounds and can act as a vehicle for food additives. We evaluated the performance of the biofilms on melon through the determination of physico-chemical and sensory properties. The results show that all the variables are significantly influenced by the biomolecule employed "modified starch", noting a favorable performance in the edible biofilms.
Los recubrimientos se definen como productos comestibles que forman una fina capa sobre el alimento y se caracterizan por que constituyen una barrera semipermeable a los gases y al vapor de agua que retrasa el deterioro del alimento, mejoran las propiedades mecánicas, ayudan a mantener la integridad estructural del producto que envuelven, ayudan a retener compuestos volátiles y pueden actuar como vehículo de aditivos alimentarios. Se evaluó el desempeño de los biorecubrimientos sobre el melón mediante la determinación de propiedades sensoriales y fisicoquímicas. Los resultados muestran que todas las variables están significativamente influenciadas por la biomolécula empleada "almidón modificado", observando un desempeño favorable en los biorecubrimientos comestibles.

Takayasu arteritis has been recognized in Colombia just recently, and so far we do not have any report concerning its presentation here. In this first report, some issues related to the presentation of the disease are indicated and compared with those found in the medical literature. No differences were found in age and sex. Most of the cases were diagnosed during an inactive phase of the disease with advanced manifestations due to vascular lesion which suggests the existence of some genetic factor influencing such a presentation, or may be the consequence of a delay in diagnosing the disease during initial and active stages due to not suspecting it. Comparing the vessels which are affected among other races and countries, we can find both differences and similarities. With the purpose of discovering the demographic, clinical, angiographic and laboratorial characteristics of Takayasu arteritis in Colombia, the present study was carried out by studying 35 clinical cases in different medical centers of the country.
