The silent epidemic
Biofilm is a complex structure of microbiome having bacterial colonies adhere to the surface. These cells are embedded in extracellular polymeric substances, a matrix generally composed of eDNA, proteins and polysaccharides, showing high resistance to antibiotics. Quorum sensing plays an important role in regulating the biofilm formation. Biofilm is one of the major causes of infection persistence especially in nosocomial settings through indwelling devices. There are many approaches being used to control biofilm. Indeed, the adhesive characteristics of natural human flora are now considered as a tool for preventing the adhesion of pathogenic bacteria to avert infection. These antibiofilm approaches represent a promising therapeutic target in the treatment of biofilm infections and development of a strong capability to interfere with different phases of the biofilm development.
Solid State NMR Spectroscopy for Biopolymers : Principles and Applications
When considering the biological significance and industrial and medical applications of biopolymers, it is crucial to know details of their secondary structure, dynamics and assembly. The biopolymers include globular, membrane and fibrous proteins, polypeptides, nucleic acids, polysaccharides and lipids. Solid state NMR spectroscopy has proved to be the most suitable and unrivaled means for investigations of biopolymers. The major advantage of solid state NMR spectroscopy is that the resulting line widths can be manipulated experimentally and are not influenced by motional fluctuation of proteins under consideration as a whole.

Inflammation and natural products ; 1st ed.
Brings together research in the area of the natural products and their anti-inflammatory action in medical, nutraceutical and food products, addressing specific chronic inflammatory diseases like cancer and the mechanistic aspects of the mode of action of some key natural products. Inflammation is a complicated process, driven by infection or injury or genetic changes, which results in triggering signalling cascades, activation of transcription factors, gene expression, increased levels of inflammatory enzymes, and release of various oxidants and pro-inflammatory molecules in inflammatory cells. Excessive oxidants and inflammatory mediators have a harmful effect on normal tissue, including toxicity, loss of barrier function, abnormal cell proliferation, inhibiting normal function of tissues and organs and finally leading to systemic disorders. The emerging development of natural product formulations utilizing the unique anti-inflammatory compounds such as polyphenols, polysaccharides, terpenes, fatty acids, proteins and several other bioactive components has shown notable successes.

Focus on bacterial biofilms
Bacterial biofilms are colonies of bacterial cells embedded in their self-produced matrix composed of polysaccharides, DNA, and proteins. They protect bacterial cells against antibiotics, antibacterial agents, soaps and detergents, and shear stress. Some of the most common biofilm-associated infections in humans include urinary tract infections, infection of wounds and surgical sites, diabetic foot ulcers, dental caries (tooth decay) and gingivitis (gum inflammation), ventilator-associated infections, sinusitis, microbial keratitis, secondary infection related to Covid-19 and other viral infections, and so on. Bacterial resistance to common antibiotics (e.g., penicillin, gentamycin, erythromycin, ciprofloxacin, etc.) is driving us to a catastrophic failure of our health systems. Strategies to develop novel antibacterial agents and technology must be prioritized to combat and eradicate biofilms and their associated challenges. This book provides a comprehensive overview of biofilms with chapters on bacterial virulence factors, quorum sensing in bacteria, antimicrobial resistance in bacteria, strategies to develop new antibacterial agents, and much more.
Esterification of Polysaccharides
Polysaccharide esters (cellulose and starch) are among the first polymeric materials applied commercially. The way of producing these technically relevant derivatives, mainly the carboxylic acid esters of C2 to C4 acids, have not been changed significantly during their history of manufacture. The investigation of new acylation methods and strategies of analysis was revived during the last decade by the search for tailored, biocompatible, material for specific fields of application, e.g., biotechnology, sensor technique and medicine. Unconventional solvents were developed for completely homo-geneous acylation reaction applying state of the art techniques of modern organic chemistry for polysaccharide modification. This book will provide a first comprehensive summary of acylation methods in a very practical manner. Detailed structure analysis is indispensable for the evaluation of structure-property-relationships. Spectroscopic methods in particular FTIR- and NMR spectroscopy including two dimensional methods are of increasing importance.
