Development of nanoparticles coated with cassava bagasse pectin (Manihot esculenta Crantz) containing β-carotene for mucoadhesive applications.

Pectin (PC) extracted from a solid residue from cassava roots (Manihot esculenta Crantz) was used to coat nanoparticles (NP) containing β-carotene (BC) aiming at the gastrointestinal administration of this lipophilic nutraceutical. The NP were prepared by spontaneous emulsification method using food grade components. Pectin-coated NP have been successfully prepared as confirmed by the increased particle size and negative surface charges due to the pectin's anionic nature.

Hematological and serum biochemistry data on southern brown howler monkeys (Alouatta guariba clamitans) in captivity in Brazil.

Background: Physiological values reflect the health condition and responses of individuals to handling in captivity. The aim of this study was to establish hematological and serum biochemistry parameters of clinically healthy animals of the Alouatta guariba clamitans subspecies.

Methods: We collected blood samples from adult males and females kept at the Center for Biological Research of Indaial after chemical containment with 3.

Nanotechnology: A Promising Tool Towards Wound Healing.

Nanotechnology is an exciting emerging field with multiple applications in skin regeneration. Nanofibers have gained special attention in skin regeneration based on their structural similarity to the extracellular matrix. A wide variety of polymeric nanofibers with distinct properties have been developed and tested as scaffolds for skin regeneration.

Phytochemical Composition, Antioxidant Activity, and the Effect of the Aqueous Extract of Coffee ( L.) Bean Residual Press Cake on the Skin Wound Healing.

The world coffee consumption has been growing for its appreciated taste and its beneficial effects on health. The residual biomass of coffee, originated in the food industry after oil extraction from coffee beans, called coffee beans residual press cake, has attracted interest as a source of compounds with antioxidant activity. This study investigated the chemical composition of aqueous extracts of coffee beans residual press cake (AE), their antioxidant activity, and the effect of topical application on the skin wound healing, in animal model, of hydrogels containing the AE, chlorogenic acid (CGA), allantoin (positive control), and carbopol (negative control).

Protective effect of green tea extract against proline-induced oxidative damage in the rat kidney.

We investigated, in vivo (acute and chronic), the effects of proline on thiobarbituric acid-reactive substances (TBA-RS) and on the activities of antioxidant enzymes such as catalase (CAT), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in renal tissues (cortex and medulla) of rats. For acute administration, 29-day-old rats received a single subcutaneous injection of proline (18.2μmol/g body weight) or an equivalent volume of 0.
