The study of epigenetic switches is very important to understand the mechanism of human development, the origin of cancer, mental illness and fundamental processes such as gene regulation. The bacteriophage epigenetic switch, which allows switching from lysogeny to lysis has recently received renewed attention. The interaction between the bacteriophage repressor and its DNA is an ideal model system to study DNA wrapping and looping and to reveal fundamental principles of long-range interactions and gene regulation by nucleoprotein complexes.
Metastasis is the main cause of mortality due to cancer; therefore, it is crucial to improve our understanding of the regulation of genes controlling the metastatic process in order to develop more effective therapies. Metastasis formation is a multi-step process resulting from genetic and epigenetic alterations in key regulatory molecules. Epigenetic regulatory mechanisms are attractive therapeutic targets as they are potentially reversible. This work focuses on the epigenetic regulation of two metastasis genes, MMP-9 and TIMP-2, in a reversible bovine cancer model induced by Theileria parasites, which allows us to study on-off switches controlling cellular invasion. I found a novel epigenetic regulator of MMP-9, the histone-modifier SMYD3, which also revealed crucial roles in the metastatic properties of human cancer cells. I showed that TIMP-2 is mainly regulated by DNA methylation in Theileria-infected cells, even though other layers of epigenetic control are present on this promoter. This work sheds light on the understanding of epigenetic events controlling metastasis genes, which should be useful for professionals and students interested in cancer genetics.
Epigenetic is heritable changes in gene expression that do not involve changes in DNA sequence,is known to be involved in disease. Two important epigenetic changes that are known to contribute to disease are abnormal methylation patterns of DNA and modifications of histones in chromatin.This therapy describes a new development in pharmacology,epigenetic therapy,which attempts to correct these changes.

Viruses are biological particles, which cause epidemics and impact on all kinds of organisms that live on this earth, including bacteria . A virus that preys on bacteria is called a bacteriophage. The main reason to learn about virus is to shield ourselves from being infected by them in the emergence of a viral epidemic or, perhaps, to live with them accommodatingly. We learned about the existence of virus just a little more than a century ago and new facts about them keep turning up all the time. There is still a great deal that we do not know about virus. We cannot produce a vaccine against viral infections such as HIV with the same concept that led to the dicovery of the first vaccine, for Smallpox, by Janner. Whether this drawback is due to the complexity of individual virus or the continued lack of certain basic knowledge of viral nature, no one can say. This book is a collection of Tirasak's bacteriophage research articles covering all sides of the argument concerning the bacteriophage and virus. It will be of benefit to anyone, who is interested in the interaction and relationship of bacteria and bacteriophage for further application of viral study.
Epigenetic is one the most important and distinct molecular pathway in colorectal cancer.The epigenetic pathway affect the level of expression of multiple cancer candidate genes essential for cell cycle control, DNA repair, and many others actions within the colon mucosa. Therefore, besides mutations, epigenetic changes including the promoters’ methylation of a set of cancer candidate genes (CAN genes) are associated with the CRC progression. Transcriptional silencing by the hypermethylation of CpG islands is an early event in tumor progression and is considered as a methylator phenotype.

The interconnection network design is determined by available technology, whose recent advances have significantly evolved basic network components as links and switches. The latter are characterized by their number of ports that is the main subject of this book. Our efforts are focused on describing an alternative solution for building high-radix switches, which consist in combining several low-radix switches. The book addresses two significant challenges of these switches: to determine the appropriate internal configuration, and to estimate the sufficient bandwidth for interconnecting low-radix switches. The most remarkable contribution is the development of a new methodology for obtaining the optimal configurations of the Combined switches. The viability and potential of this alternative are evaluated considering aspects like the network performance and cost. Such evaluation has been driven by comparing these aspects for single-chip-based and Combined-switch-based networks. In particular, optimal and non-optimal configurations for Combined switches are considered. Moreover, single-chip switches of different radixes are used to perform the comparison among the networks.

Epigenetics is a term in biology referring to heritable traits that do not involve changes in the underlying DNA sequence of the organism. Epigenetic traits exist on top of or in addition to the traditional molecular basis for inheritance. The «epigenome» is a parallel to the word «genome,» and refers to the overall epigenetic state of a cell. Cancer and stem cell research have gradually focused attention on these genome modifications. The molecular basis of epigenetics involves modifications to DNA and the chromatin proteins that associate with it. Methylation, for example, can silence a nearby gene and seems to be involved in some cancers. Epigenetics is beginning to form and take shape as a new scientific discipline, which will have a major impact on Medicine and essentially all fields of biology. Increasingly, researchers are unearthing links between epigenetics and a number of diseases. Although in recent years cancer has been the main focus of epigenetics, recent data suggests that epigenetic plays a critical role in psychology and psychopathology. It is being realized that normal behaviors such as maternal care and pathologies such as Schizophrenia and Alzheimer's might have an epigenetic basis. It is also becoming clear that nutrition and life experiences have epigenetic consequences. Discover more online content in the Encyclopedia of Molecular Cell Biology and Molecular Medicine.
Singlehood is seen as a lifestyle capable of successfully fulfilling human needs. In today’s society, more and more people are choosing to live alone. Single living refers to a household consisting of one person. Singlehood is a multi- dimensional problem. The study is significant at two levels. First and foremost, it is proposed to bring out the factors and problems of singlehood. Secondly, to reveal the relevance of the support system and the life satisfaction level in the life of single women. Present study is an analysis of the dilemmas faced by the single women of Kerala. The Singleton has emerged as a distinct social category in the rapidly changing Kerala society. The present study attempts to show the change from Spinster to Singleton and the generation differentials of single women in Kerala. The study also made an attempt to find out the socio-cultural background of the single women, the factors that led women of Kerala to singlehood, their adjustment to this status, the stress associated with it, the problems they encounter, the support system they enjoy and the level of life satisfaction they have in their unique life style.

Revision with unchanged content. This study examines the factors that influence the simultaneous adoption of no-till farming technology and Roundup Ready soybean (RR) varieties and the welfare benefits of the adoption of the technologies. The single adoption of the individual technologies is analyzed using a feasible generalized least squares (FGLS) estimation. A two-limit Tobit procedure is further used to analyze the extent of the adoption of the technologies. To answer the question of the simultaneity between the two technologies, we construct a Wu-Hausman test statistic using the results of two separate single equation probit models and a simultaneous two-equation econometric model. Furthermore, the book provides readers with a simple way of analyzing the welfare benefits of adopting a new technology in the case of a parallel and a pivotal shift of the supply curve. The theoretical model developed assumes two main regions; a large producer country adopting the new technology (U.S.) and the rest of the world (ROW), as the non-adopting region. Economic surpluses gained by producers and consumers in the two regions are discussed. This book is aimed at providing professionals, policy makers, researchers and intermediate to graduate level students in economics with simple but rigorous strategies that can be used in modeling and analyzing the concomitant adoption of technologies.
The mixture of two regression regimes has been extensively studied in economics. The test of a mixture of regimes in hazard modeling would be seen to have fundamental importance in biostatistical research but has not been studied. A two-regime parametric mixture is proposed to model the effect of a single covariate on the event time. Typically, the Cox proportional hazards model is applied to estimate a single regime survival regression function. The mixture of two regimes model contains five parameters to be estimated; namely, two parameters to describe each regime, and one to describe the mixing proportion. A software program developed for this research finds the maximum likelihood estimates of the parameters and the likelihood ratio test of the null hypothesis of a single regime against the alternative of a mixture of two regimes. A simulation study finds an approximation to the null distribution of the test and its approximate power.
Electrochemical behavior of Paracetamol in aqueous media has been studied by three electroanalytical techniques namely CV, SWV & DPV with GCE. Many Voltammetric parameters have been optimized and their influence in peak current and peak potential were studied. A quasi-reversible reaction with the transfer of two electrons per molecule of Paracetamol was observed. As the pH increases the anodic peak potential drastically shifts to the negative potential, which indicates that hydrogen ion takes part in the electrochemical oxidation of Paracetamol.24 The maximum peak current was observed at pH 7. The effect of concentration and scan rate on anodic peak current has been studied. In conclusion the Voltammetric study of Paracetamol requires no purification or extraction steps. Electroanalytical techniques have a major advantage in time and economy in the study.
