Over the years, natural products such as essential oils have been gaining more and more prominence due to their perceived health benefits. Plants rich in essential oils represent a viable source of biomolecules for use in the most varied human activities, such as agricultural, cosmetic, and pharmaceutical applications. Essential oils are natural volatile fractions extracted from aromatic plants that are formed by classes of substances such as fatty acid esters, mono and sesquiterpenes, phenylpropanoids, and aldehyde alcohols, and in some cases, aliphatic hydrocarbons, among others. In this context, this book includes twelve chapters that present new information on the extraction and application of essential oils in various industrial segments. It is divided into three sections that discuss the general concepts of essential oils and techniques for their extraction, topics in food science and technology, and essential oils and their pharmacological properties in various activities and applications.
The book explores distinct aspects of protein purification and characterization steps. It discusses solubility problems, resin selection tricks, and essential credentials in a purification process. In addition, the book examines aggregation and proteinopathy-related protein detection methods and reviews several essential protein detection and characterization methods in cancer for diagnosis, prognosis, and therapy, such as enzyme-linked immunosorbent assay (ELISA), immunohistochemistry, flow cytometry, western blot, mass spectrometry, and others.
Cell culture is cell cloning technology that simulates in vivo environment conditions such as asepsis, appropriate temperature, and pH as well as certain nutritional conditions to enable cells to survive, grow, reproduce, and maintain their structure and function. Cell culture can be used to grow human, animal, plant, and microbial cells. Each type of cell culture has its own characteristics and essential conditions. This book focuses on the advanced technology and applications of cell culture in the research and practice of medical and life sciences. Chapters address such topics as primary cancer cell cultures, 2D and 3D cell cultures, stem cells, nanotechnology, and more.
This book gives a current review of the links between the structure and function of hydrolases and ligases, as well as ideas for better using these critical enzymes. The book is split into two sections: ¿Cleavage¿ and ¿Ligases.¿ These enzymes are the biggest and most varied family of enzymes, allowing researchers to investigate the structural variety that underpins their different biological roles. In light of recent scientific advances, there is a desire to examine and update our knowledge of these enzymes¿ functional and structural changes.
The term "reactive oxygen species" (ROS) refers to a group of reactive molecules and free radicals produced by molecular oxygen. In recent decades, there has been great interest in the role of ROS in various diseases. From basic science research to clinical trials, biomedical scientists have made rapid progress toward a better understanding of ROS-metabolizing systems and their role in health and diseases. This book includes sixteen chapters that address topics such as the history of ROS, its role in autoimmunity, neurodegeneration, and aging, and recent advances in various antioxidants and their therapeutic potential.
Skin cancers, basal and squamous cell carcinomas, malignant melanomas, and Merkel cell carcinomas, constitute arguably the most common and increasingly prevalent human neoplasms. Here we discuss the epigenetic changes in DNA and chromatin, which are increasingly associated with melanoma. Several chapters focus on the posttranscriptional modification of the proteins at the melanocyte cell surface, their role in tumorigenesis, and their potential as therapeutic targets. Specifically, extracellular modifications of integrins, glycosylation of cell surface proteins, and changes of cadherins are presented. In a very interesting approach, a potential to target the mitochondria of melanoma cells is investigated. In conclusion, this volume presents various aspects of human skin cancers, components of the large worldwide effort to combat and eradicate this growing health concern.
