TL;DR: A survey of the Ganga-meghna-Brahmaputra (GMB) plain over the past 20 years and analysis of more than 220,000 hand tube-well water samples revealed groundwater arsenic contamination as mentioned in this paper.
Abstract: The authors’ survey of the Ganga–Meghna–Brahmaputra (GMB) plain (area 569,749 km2; population >500 million) over the past 20 years and analysis of more than 220,000 hand tube-well water samples revealed groundwater arsenic contamination in the floodplains of the Ganga–Brahmaputra river (Uttar Pradesh, Bihar, Jharkhand, West Bengal, and Assam) in India and the Padma–Meghna–Brahmaputra river in Bangladesh. On average, 50 % of the water samples contain arsenic above the World Health Organization guideline value of 10 μg/L in India and Bangladesh. More than 100 million people in the GMB plain are potentially at risk. The authors’ medical team screened around 155,000 people from the affected villages and registered 16,000 patients with different types of arsenical skin lesions. Arsenic neuropathy and adverse pregnancy outcomes have been recorded. Infants and children drinking arsenic-contaminated water are believed to be at high risk. About 45,000 biological samples analyzed from arsenic-affected villages of the GMB plain revealed an elevated level of arsenic present in patients as well as non-patients, indicating that many are sub-clinically affected. In West Bengal and Bangladesh, there are huge surface water in rivers, wetlands, and flooded river basins. In the arsenic-affected GMB plain, the crisis is not over water scarcity but about managing the available water resources.

TL;DR: It was concluded that these IPN microspheres provided oral controlled release of water-soluble DS and showed a Fickian trend of drug release which depends on the extent of cross-linking and the ratio of XG:PVA present in the microsphere.
Abstract: Xanthan gum (XG), a trisaccharide branched polymer and poly vinyl alcohol (PVA), was used to develop pH-sensitive interpenetrating network (IPN) microspheres by emulsion cross-linking method in the presence of glutaraldehyde as a cross-linker to deliver model anti-inflammatory drug, diclofenac sodium (DS) to the intestine. Various formulations were prepared by changing the ratio of XG:PVA, extent of cross-linking in order to optimize the formulation variables on drug encapsulation efficiency, and release rate. Formation of interpenetrating network and the chemical stability of DS after penetration of microspheres was confirmed by Fourier Transform infrared (FTIR) spectroscopy. Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) analysis were done on the drug loaded microspheres which confirmed molecular dispersion of DS in the IPN. Microspheres formed were spherical with smooth surfaces, as evidenced by scanning electron microscopy (SEM), and mean particle size, as measured by laser light scattering technique ranged between 310.25-477.10 microm. Drug encapsulation of up to 82.94% was achieved as measured by UV method. Both equilibrium and dynamic swelling studies and in vitro release studies were performed in pH 1.2 and 6.8. Release data indicated a Fickian trend of drug release which depends on the extent of cross-linking and the ratio of XG:PVA present in the microsphere. When subjected to in vivo pharmacokinetic evaluation in rabbits, microparticles show slow and prolonged drug release when compared with DS solution. Based on the results of in vitro and in vivo studies it was concluded that these IPN microspheres provided oral controlled release of water-soluble DS.

TL;DR: In this article, an interpenetrating network (IPN) matrix tablet of diltiazem-HCl (DTZ) was prepared by wet granulation method using polyacrylamide-grafted-sodium alginate (PAam-g-SAL) co-polymer and sodium alginates (SAL), for sustained release of the drug.
