  • There is a commonly held myth in our society that anything that is “natural” is good, wholesome, and healthful, whereas anything that is “synthetic” is bad, toxic, and harmful. The mere mention of the word chemical is enough to strike terror into the heart of any food faddist. This attitude is, at best, naïve and, at worst, dangerous.

  • Two types of finishes help protect fabrics. Silicone (such as Sylmer) finishes repel water-based substances. Fluorochemical (such as Scotchguard, Zepel) finishes protect against both water-based and oil-based spills. Both types of finishes repel spills long enough to be wiped up, but they do not replace cleaning. These finishes are applied to the fabric surface and will wear off after extended use and cleaning. These finishes are applied to the fabric surface and will wear off after extended use and cleaning.

  • The global demand for organically produced food is rising. In 2007 the organic food market in the UK was estimated to be worth over £2 billion – an increase of 22% since 2005 (6). The UK organic market is now the third largest in Europe after Germany and Italy. Fruit and vegetables comprise the largest sector of organic foods in the UK, closely followed by dairy products. The shift in demand among consumers from conventionally to organically produced foodstuffs appears to have arisen at least in part from a belief that organically produced foodstuffs are healthier...

  • Commercially useful lipases are usually obtained from microorganisms that produce a wide variety of extracellular lipases. Many lipases are active in organic solvents where they catalyze a number of useful reactions including esterification (Chowdary et al., 2001; Hamsaveni et al., 2001; Kiran et al., 2001a; Kiyota et al., 2001; Krishna and Karanth, 2001; Krishna et al., 2001; Rao and Divakar, 2001), transesterification, regioselective acylation of glycols and menthols, and synthesis of peptides (Ducret et al., 1998; Zhang et al.

  • Because of the asymptomatic process of carcinogenesis, the early detection of cancers such as hepatocellular carcinoma (HCC) is very challenging. Tumor-prone transgenic mouse models of oncogenesis can provide a stable and powerful tool for the analysis of cancer initiation, and are therefore promising for the discovery of early putative biomarkers of HCC.

  • Students conduct mechanistic and translational research on: the causes of breast, liver, lung and prostate cancer, inflammatory processes in cardiomyopathy, signal pathway disruption in cardiac hypertrophy, chronic obstructive pulmonary disease (COPD), autoimmunity, neurodevelopmental disorders and identification of pathways of toxicity. Seminars, journal clubs and research retreats are an integral part of the student experience.

  • Over the last three decades, knowledge on the molecular biology of human cancers has vastly expanded. A host of genes and proteins involved in cancer development and progression have been defined and many mechanisms at the molecular, cellular and even tissue level have been, at least partly, elucidated. Insights have also been gained into the molecular mechanisms underlying carcinogenesis by chemical, physical, and biological agents and into inherited susceptibility to cancer. Accordingly, Part I of the book presents many of the molecules and mechanisms generally important in human cancers.

  • Cancer Chemoprevention Chemoprevention involves the use of specific natural or synthetic chemical agents to reverse, suppress, or prevent carcinogenesis before the development of invasive malignancy. Cancer develops through an accumulation of genetic and epigenetic changes that are potential points of intervention to prevent cancer. The initial changes are termed initiation. The alteration can be inherited or acquired through the action of physical, infectious, or chemical carcinogens.
