Book SynopsisLignin is the main natural resource of aromatic structures on Earth. With the depletion of fossil oil and increased environmental concerns, renewable resources for energy and chemical production have attracted tremendous attention from scientists and engineers. As a renewable aromatic polymer, lignin has been, for a long time, studied in terms of its biosynthesis, structures, reactivities and applications although few portions of lignins available from the industry, mainly pulping mills, have been utilised for various applications. The key for complete and efficient utilisation of lignins is that all aspects, including lignin biosynthesis, structures, functionalities, and properties, about lignins should be understood. Another important attribute related to lignin utilisation comes from analytical methods essential for our understanding of lignins and mechanisms involved in various processes. This book provides critical reviews and the latest research results relating to selected fields of lignin biosynthesis, functional characterisation and applications.

Book SynopsisIn response to various environmental cues and cellular stress, cells need to modify their protein expression pattern for proper cell functioning. The cell experiences diverse cellular stress as oxidative, genotoxic, and etc. The damage of the genome by certain chemicals or agents affects the cell integrity and leads to genotoxic stress. As such, this compilation discusses how different cellular stresses affect the polyadenylation process and modulate the polyadenylation machinery. Cytoplasmic polyadenylation plays an important role in oocyte maturation, mitotic cell cycle progression, cellular senescence and synaptic plasticity. Poly(A) tails can be elongated post-transcriptionally by noncanonical poly(A) polymerases, which can impact cells with limited transcriptional activity. A recent study is discussed wherein it is shown that that alternative cleavage and polyadenylation isoform expression influences about 10% of targeting by miRNAs between any two cell types analysed and, more importantly, that the accuracy of target prediction can be improved if the cellular alternative cleavage and polyadenylation profile is considered. The authors go on to focus on how altering the polyadenylation process and components of RNA polyadenylation machinery leads to abnormal physiological conditions. The targeting of elements of RNA polyadenylation machinery as therapeutics in clinical research is also discussed. The majority of eukaryotic mRNAs are polyadenylated at their 3'end. This poly(A) tail is not encoded by DNA and is added co-transcriptionally. Cleavage and polyadenylation specific factor (CPSF1) is part of multiple subunit factors required for a site-specific cleavage, which is involved in determining specificity and efficency of the 3' end processing of pre-mRNAs in the nucleus by recognizing the polyadenylation signal. Following this, mutations in the poly(A) signal (AAUAAA hexamer) present in the globin pre-mRNA were identified in hematological disorders caused by defects in the synthesis of one or more of the globin chains (thalassemia). The point mutation AATAAA to AACAAA of a human β-globin gene detected in 1985 in DNA from a patient with β-thalassemia led to the formation of an elongated β-globin mRNA isoform. This compilation addresses how RNA processing at the pre-mRNA level occurs in the cell nucleus and regulates gene expression. Newly synthesized mRNA contains a poly(A) tail, which is added through canonical polyadenylation coupled to transcription. Canonical mRNA 3' processing involves endonucleolytic cleavage within the pre-mRNA sequences and the addition of a poly(A) tail to the upstream cleavage fragment. The closing chapter discusses how the poly(A) tail at the 3'end of the majority of eukaryotic messenger RNAs (mRNAs), with the exception of histone transcripts, is not simply a static entity but more likely a dynamic matter. Its length added to an mRNA is regulated by the concerted action of poly(A) polymerases and deadenylases.Table of ContentsFor more information, please visit our website at:https://novapublishers.com/shop/a-closer-look-at-polyadenylation/

Book SynopsisPesticides belonging to carbamate and organophosphate groups have the potential to induce oxidative stress. However, the role of aqueous extract of A. vera has not been properly studied to demonstrate its ameliorative potential against the toxicity induced by these pesticides in single and combination in different organs of mammalian systems. After an extensive literature survey on the subject, an endeavour has been made to define the following objectives in order to fill up the existing lacuna of information about cartap and malathion induced oxidative stress in rat blood, brain and liver and its impact on neurotransmission as well as energy metabolism. Liver and blood were also included in this study for establishing a more meaningful agreement. The present study was therefore undertaken to delineate the differential impacts of cartap and malathion on the biochemical and histological parameters in Wistar rats. In addition, the prophylactic effect of aqueous extract of A. vera leaves has also been evaluated. The objectives of the present study include: evaluation of xenobiotic-induced oxidative stress, determination of activity of acetylcholinesterase and other esterases in the brains of rats exposed to xenobiotics as potential biomarkers of neurotoxicity; evaluation of different enzymes of energy metabolism in rats exposed to xenobiotics; measurement of specific parameters concerning the function of the kidney and liver in rats exposed to xenobiotics; evaluation of AChE isozyme profile to specifically understand the target of xenobiotics in the brain of rats; analysis of patterns of major biomolecules (proteins/DNA) in rats exposed to xenobiotics for different treatment durations; and assessment of the ameliorative impact of phytochemicals, if any, on xenobiotics. This book is divided into eight sections. Section 1 contains the general introduction and background of the study. Section 2 contains an extensive literature survey on the subject so as to present updated information. Section 3 demonstrates the main objectives of the study. Section 4 describes the various experimental designs, procedures, protocols, tools and techniques. Section 5 illustrates the data obtained from this study. Section 6 enumerates the discussion of the data and associated mechanisms. Section 7 includes the summary and conclusion of the entire study. Section 8 includes citations and references used in this work. This book contains many specific diagrams, illustrations and presentations in simple tables and figures which are self-explanatory so as to make any reader well versed to this subject. In addition, specific flow charts are added to simplify the presentation. We hope that this publication will be of great use to graduates, postgraduates, researchers and faculty members who are studying in the field of plant-based principles for alleviating pesticide toxicity and associated diseases. The tools and techniques explained in this title could be of immense use to all those working in this area. The authors welcome comments and suggestions to improve the quality of the content in the next edition.Table of ContentsPreface; About the Authors; Acknowledgments; Introduction; Review of Literature; Materials and Methods; Results; Discussion; Summary and Conclusion; References; List of Publications; Index.

Book SynopsisIn biological systems, the normal processes of oxidation (plus a minor contribution from ionising radiation) produce highly reactive free radicals. These can readily react with and damage other molecules. In some cases the body uses free radicals to destroy foreign or unwanted objects, such as in an infection. However, in the wrong place, the body''s own cells may become damaged. Should the damage occur to DNA, the result could be cancer. Antioxidants decrease the damage done to cells by reducing oxidants before they can damage the cell. Virtually all studies of mammals have concluded that a restricted calorie diet extends the lifespan of mammals by as much as 100%. This remarkable finding suggests that food is actually more damaging than smoking. As food produces free radicals (oxidants) when metabolised, antioxidant-rich diets are thought to stave off the effects of ageing significantly better than diets lacking in antioxidants. The reduced levels of free radicals, resulting from a reduction in their production by metabolism, is thought to be a major cause of the success of caloric restriction in increasing life span. Antioxidants consist of a group of vitamins including vitamin C, vitamin E, selenium and carotenoids (such as beta-carotene, lycopene, and lutein). This new book brings together the latest research in this dynamic field.

Book SynopsisComputational models have been playing a significant role for the computer-based analysis of biological and biomedical data. Given the recent availability of genomic sequences and microarray gene expression data, there is an increasing demand for developing and applying advanced computational techniques for exploring these types of data such as functional interpretation of gene expression data, deciphering of how genes and proteins work together in pathways and networks, extracting and analysing phenotypic features of mitotic cells for high throughput screening of novel anti-mitotic drugs. Successful applications of advanced computational algorithms to solving modern life-science problems will make significant impacts on several important and promising issues related to genomic medicine, molecular imaging, and the scientific knowledge of the genetic basis of diseases.

Book SynopsisAntisense molecules interact with complementary strands of nucleic acids, modifying expression of genes. Some regions within a double strand of DNA code for genes, which are usually instructions specifying the order of amino acids in a protein along with regulatory sequences, splicing sites, non-coding introns and other complicating details. For a cell to use this information, one strand of the DNA serves as a template for the synthesis of a complementary strand of RNA. The template DNA strand is called the transcribed strand with antisense sequence and the mRNA transcript is said to be sense sequence (the complement of antisense). Because the DNA is double-stranded, the strand complementary to the antisense sequence is called non-transcribed strand and has the same sense sequence as the mRNA transcript (though T bases in DNA are substituted with U bases in RNA). This book presents important new research from around the world in this field.

Book SynopsisFood chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This new book presents the latest selected research from around the world.

Book SynopsisImmunosuppression involves an act that reduces the activation or efficacy of the immune system. Some portions of the immune system itself have immuno-suppressive effects on other parts of the immune system, and immunosuppression may occur as an adverse reaction to treatment of other conditions. Deliberately induced immunosuppression is generally done to prevent the body from rejecting an organ transplant, treating graft-versus-host disease after a bone marrow transplant, or for the treatment of auto-immune diseases such as rheumatoid arthritis or Crohn''s disease. This is typically done using drugs, but may involve surgery (splenectomy), plasmapharesis, or radiation. A person who is undergoing immunosuppression, or whose immune system is weak for other reasons (for example, chemotherapy and HIV patients) is said to be immunocompromised. When an organ is transplanted, the immune system of the recipient will most likely recognise it as foreign tissue and attack it. The destruction of the organ will, if untreated, end in the death of the recipient. In the past, radiation therapy was used to decrease the strength of the immune system, but now immunosuppressant drugs are used to inhibit the reaction of the immune system. The downside is that with such a deactivated immune system, the body is very vulnerable to opportunistic infections, even those usually considered harmless. Also, prolonged use of immunosuppressants increases the risk of cancer. This book presents the latest research in the field.

Book SynopsisMagnesium is the fourth most abundant mineral in the body and is essential to good health. Approximately 50% of total body magnesium is found in bone. The other half is found predominantly inside cells of body tissues and organs. Only 1% of magnesium is found in blood, but the body works very hard to keep blood levels of magnesium constant. Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and protein synthesis. There is an increased interest in the role of magnesium in preventing and managing disorders such as hypertension, cardiovascular disease, and diabetes. Dietary magnesium is absorbed in the small intestines. Magnesium is excreted through the kidney. This book presents the latest research in the field.

Book SynopsisThe activity of a bacterial enzyme "able to degrade penicillin" had first been described in 1940, even before the exact structure of penicillin was elucidated and, by 1970, several enzymes had been purified to homogeneity, the amino acid sequence of a staphylococcal penicillinase was also known and that of its Bacillus licheniformis counterpart was well under way. By contrast, their catalytic mechanism remained quite mysterious. A Zn++ metallo-beta-lactamase (ß-lactamase II, BcII or ßII) had also been described as soon as 1967 and later purified. It was thus surprising that the first mechanistic information demonstrating the presence of a penicillin-binding serine residue was obtained with a penicillin-sensitive DD-peptidase rather than a ß-lactamase. This seemed to open the floodgates and several class A ß-lactamases were then rapidly shown to be active-site serine enzymes. This book presents current research in the study of beta-lactamases.
