Al-Zahraa M Khalifa, Bazigha K Abdul Rasool
The objective of this study is to develop an oral formulation of famotidine niosomes coated with a mucoadhesive polymer, chitosan. Famotidine (FMT) has low oral bioavailability of 40-45% and short half-life between 2.5 to 4 h. Famotidine is classified as class IV in BCS because of its low aqueous solubility (0.1% w/v) and low permeability. Thus, FMT was loaded to the bioadhesive coated niosomes to improve its solubility, enhance its oral bioavailability, and sustain FMT release pattern. Different formulations were prepared by thin-film hydration method and characterized in terms of entrapment efficiency, morphological features, vesicle size, and zeta potential...

Silibinin is a natural flavonoid with a strong antioxidant property and weak cytotoxic activity. It has demonstrated anti-tumoural activity against many types of malignancies; however, due to its hydrophobic structure, it has poor water solubility, bioavailability and permeability across intestinal epithelial cells. To improve the effect of silibinin, we have vehiculated silibinin by a highly stable niosomal nanostructure based on a Span 60/cholesterol (CH)/N-trimethyl chitosan (TMC) system in order to study its potential application for the delivery of silibinin in T47D cultured under three-dimensional (3D) and two-dimensional (2D) conditions...

REVIEW
N P Aditya, Yadira Gonzalez Espinosa, Ian T Norton
Increased health risk associated with the sedentary life style is forcing the food manufacturers to look for food products with specific or general health benefits e.g. beverages enriched with nutraceuticals like catechin, curcumin rutin. Compounds like polyphenols, flavonoids, vitamins are the good choice of bioactive compounds that can be used to fortify the food products to enhance their functionality. However due to low stability and bioavailability of these bioactives (both hydrophobic and hydrophilic) within the heterogeneous food microstructure and in the Gastro Intestinal Tract (GIT), it becomes extremely difficult to pass on the real health benefits to the consumers...

The skin, being the outermost layer of our body, is constantly exposed to oxidative stress induced by UV-radiation, pollutants, smoke and xenobiotics. To counteract the deleterious effects of such exposure, the skin is equipped with a complex anti-oxidation system, involving both exogenous and endogenous antioxidants. As low molecular weight antioxidants undergo depletion in counteracting oxidative stress occurring in the skin, topical supplementation with these agents is regarded as a suitable strategy to restore skin oxidative balance...
