Postmenopausal women exhibit a reduced alveolar bone mass and lowered levels of serum total calcium with the increasing age. These changes may be useful indicators for low skeletal bone mineral density or osteoporosis.
In this review study about the polymeric nanoparticles and how polymer based nanoparticles increase bioavailability of less water soluble drugs. Polymeric nanoparticles have a matrix of biodegradable and biocompatible polymers of synthetic and natural origin. Polymer based nanoparticles are very useful for increase the solubility of the poor water-soluble drugs by decrease the particles size. Polymeric nanoparticles are very useful for targeting the drug to the specific site. Polymeric nanoparticles are also used to maintain and control the release of the drug. In present review study on the type of polymer used for the preparation of the polymer based nanoparticles. The choice of method depends on a number of factors, such as, particles size, area of application and characterization of polymeric nanoparticles.
Toxic and difficult to biodegrade pharmaceutical wastewater is complex in composition with high concentrations of organic debris and microorganisms. There may still exit quantities of suspended particles and dissolved organic materials even after further treatment. Advanced treatment is required to improve the quality of pharmaceutical wastewater discharge. In this study, the pharmaceutical technology categorization has been established, and the features of pharmaceutical wastewater effluent quality have been summarized. On the other hand, The methods of advanced treatment of pharmaceutical wastewater have been incorporate, including coagulation and sedimentation, flotation, activated carbon adsorption, membrane separation, advanced oxidation processes, membrane separation, and biological treatment. In the meanwhile, each process's features were specified.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
