Biopolymers and composites: Properties, characterization and their applications in food, medical and pharmaceutical industries

Abstract: Polymers have occupied an indispensable role in almost all types of industries for their immense physical and mechanical characteristics, mainly in food, packaging, pharmaceutical and therapeutic sectors. They were synthesized from chemical monomeric sources which paved the way to become a potentially harmful non-biodegradable waste in the environment. Here comes the introduction of biopolymers, as the organic substances present in natural sources as monomeric units that can be purified and processed based on the desired form of usage. These biopolymers were found to be biocompatible and biodegradable which makes them useful in different applications, such as edible films, emulsions, packaging materials in food industry and as drug transport materials, medical implants like organ, tissue scaffolds, wound healing and dressing materials in pharmaceutical industries. The main focus of this review is to provide a comprehensive knowledge about the physical, thermal, mechanical and optical properties of biopolymers and its composites in relation with the different characterization techniques. A detailed information of its usage in the food and pharmaceutical industries in different forms would be discussed with the upcoming trends thereby providing a wide avenue for enhanced research considering the future demands.

Pollutants inducing epigenetic changes and diseases

Abstract: Pollution is a major issue impacting the health of life and ecosystems. In particular, some pollutants may alter gene expression by epigenetic mechanisms such as deoxyribonucleic acid (DNA) methylation, histone modifications, and microRNA (miRNA) expression. Epigenetics is the study of heritable changes without alteration in the DNA sequence. In the healthy state, the coordinated actions of interconnected epigenetic factors are responsible for proper cell development and cell regulation. Epigenetic mechanisms are tissue-specific; hence, a pollutant may or may not cause an alteration depending on the type of tissue. Here we review mechanisms by which pollutants disrupt epigenetic factors. We focus on the impact of arsenic, cadmium, nickel, mercury, benzene, bisphenol A, dioxin, hexahydro-1,3,5-trinitro-1,3,5-triazine and diethylstilbestrol. A list of diseases related to epigenetic factors and heavy metals exposure is provided.

The Design and Analysis of Experiments

Abstract: THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.
