7. Paullinia cupana: a multipurpose plant - a review
Abstract Seeds of guarana (Paullinia cupana Kunth, Sapindaceae) feature diverse pharmacological functions, for example, antimicrobial, antioxidant, anticarcinogenic, stimulating, and cognitive functions, as well as liver protection and weight loss. Many of these actions are probably due to the high content of methylxanthines and tannins in its seeds. In Braz

9. Appraisal of acute oral toxicity of glucuronoxylan hydrogel from Mimosa pudica seeds
Glucuronoxylan hydrogel (GXH) isolated from M. pudica seeds was assessed for acute toxicology in albino mice that were alienated into four groups. Three groups, i.e., II, III and IV received GXH at a dose of 1, 2 and 5 g/kg, respectively while group I was retained untreated and provided routine diet. After administering GXH, mice were examined for vomiting,

11. Production, characterization and toxicology assay of creatine pegylated nanoliposome with polysorbate 80 for brain delivery
ABSTRACT Creatine acts intracellularly as energy buffer and storage, demonstrating protective effects in animal models of neurodegenerative diseases. However, its permeability throught blood-brain barrier (BBB) is reduced. The aim of the present study was developing a carrier to facilitate the delivery of creatine to the central nervous system. Creatine nano
