  • Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet that includes plenty of vegetables and fruits is healthy, and official U.S. Government policy urges people to eat more of these foods. Research has shown that people who eat more vegetables and fruits have lower risks of several diseases; however, it is not clear whether these results are related to the amount of antioxidants in vegetables and fruits, to other components of these foods, to other factors in people’s diets, or to other lifestyle choices....

  • After many years of studying microbiology, biofilms, and public health, it became my ambition to produce a book on these three areas. Having researched substantially into the formation and development of biofilms, particularly in potable water, I felt a book that could consolidate all the information on their public health significance was needed. This book provides a snapshot of public health and water with an appreciation of what a biofilm is and how well it presents a safe haven for pathogens, while factorizing unreported and reported water-related diseases....

  • The successful epidemiologic evaluation of any particular disease or condition has several prerequisites. Two of the most important prerequisites are that the condition should be accurately defi ned and that there should be measurable outcomes of interest. Another requirement is that there must be some systematic way of data collection or surveillance that will allow the measurement of the outcomes of interest and associated risk factors. The epidemiologic evaluation of critical illness associated with pregnancy has met with mixed success on all of these counts....

  • Cancers of the endometrium, ovary and cervix share certain characteristics. However, etio-pathogenesis of all the gynecological malignancies is yet to be explored. Even though the etiologic factors are generally environmental, the exact cause of each gynecological cancer is not known (Senate Community Affairs References Committee, Commonwealth of Australia, 2006). Worldwide, cancer incidence rates vary widely between different geographic regions and ethnic groups.

  • Cardiovascular disease, including coronary heart disease, strokes and diseases of other arteries, is a major cause of early death and disability. For many years the major markers of disease risk have been well recognised: these include high blood cholesterol levels and smoking. But it has also been recognised that these markers do not account for all cardiovascular risk. Furthermore, treatments that are highly effective in altering these markers, for instance the ‘statin’ drugs used to lower cholesterol, do not remove risk entirely: typically they reduce it by about 30% or less.

  • The prognosis for individuals with liver cancer is frequently poor. Cancers include those which have metastasized to the liver from elsewhere, reflecting advanced stage disease where cure is rarely possible. Similarly, primary liver cancer frequently complicates chronic liver disease, which further limits therapeutic options. Despite these dismal facts, there are signs that change is imminent. Not only have imaging modalities and surgical techniques improved, but preventive strategies and medical therapies show promise.

  • Characterization of animal genetic resources for food and agriculture (AnGR) involves three types of information: phenotypic, genetic and historical. The weight given to each depends on the country (e.g. whether it is developed or developing) and the objective (e.g. improve- ment, conservation or breed differentiation). These guidelines focus on the collection and use of phenotypic information.

  • The immune system, composed of a variety of cell types and soluble factors, is geared toward the recognition of and response to "foreign" substances termed antigens. Vaccines convey antigens from living or killed microorganisms (or protein or carbohydrate molecules derived from these antigens) to elicit immune responses that are generally protective but can occasionally backfire and cause harm to the recipient.

  • Haemophilus influenzae was first recognized in 1892 by Pfeiffer, who erroneously concluded that the bacterium was the cause of influenza. The bacterium is a small (1- by 0.3-µm) gram-negative organism of variable shape; hence, it is often described as a pleomorphic coccobacillus. In clinical specimens such as cerebrospinal fluid (CSF) and sputum, it frequently stains only faintly with phenosafranin and therefore can easily be overlooked. H. influenzae grows both aerobically and anaerobically.

  • Neither randomized clinical trials nor meta- analysis are available and evidence is based on a number of retrospective studies with multivariate for mortality risk factors or data from national cancer registries (Gilliland et al., 1997; Hundahl et al., 1998). Unfortunately, very remarkable differences in patient’s selection, staging systems, and clinical management affect the available studies. In particular, radioiodine treatment is not routinely carried out in a standard manner and outcome results of different studies are thus not comparable (Sciuto et al., 2009).
