  • At the beginning of the 21st century, medicine is increasingly based on understanding the functions of genes and the molecular mechanisms of diseases. In pancreatology, the understanding of functions and dysfunctions of the exocrine and endocrine pancreas is derived from molecular biological data on the actions of compounds in subcellular compartments and intracellular transcription pathways.

  • In an ideal world, marketing and sales create a shared go-to-market strategy that focuses on customers, not products. In this world, marketing creates demand with the right kinds of (profitable) prospects as well as promoting the brand, and sales has the insight and selling tools it needs to close those sales. This foundation of joint ownership and continuous information sharing is enabled by accessible and flexible technology.

  • Combined methods have led to further refinements with, for example, high visuospatial resolution afforded by MRI combined with metabolic information from the lesion site (measured with 18F-fluorodeoxyglucose positron emission tomography; FDG-PET) to indicate location and malignancy of gliomas, which in turn informs radiosurgical targeting. Kapsalaki et al. (Chapter 7) consider MRS spectroscopic profiles for differentiation among ring enhancing lesions including high grade gliomas, abscesses and post-radiation necrosis.

  • In addition to an in-depth knowledge and understanding of the scientific and clinical aspects, veterinary students also need to have a grasp of the legal, ethical and social elements of veterinary practice. Thus, communication and interpersonal skills; responsible and professional behaviour, and an understanding of the business context of veterinary practice are now recognized as important areas that should be incorporated into veterinary curricula.

  • Of the four heart valves, the mitral valve is the only valve that has a distinguishable annulus. However, the presence of a fibrous annular structure is variable and discontinuous. The firmest site of support for the mitral valve is the region of fibrous continuity between the aortic and mitral valves, the extent of which is delineated by the right and left fibrous trigones (Fig. 2). Nevertheless, for surgical purposes, the annulus is considered the area of attachment of the valve leaflets to the atrial muscle. The annulus is a functional component of the mitral valve.

  • In Chapter 1 we present in detail a framework for fully automated brain tissue classification. The framework consists of a sequence of fully automated state of the art image registration (both rigid and nonrigid) and image segmentation algorithms. Models of the spatial distribution of brain tissues are combined with models of expected tissue intensities, including correction of MR bias fields and estimation of partial voluming. We also demonstrate how this framework can be applied in the presence of lesions....

  • The statistics are well known and staggering. And yet, in many countries the figures continue to worsen. Each year 500,000–600,000 women die in pregnancy and childbirth. In some parts of Sub–Saharan Africa, 1 in 6 women die in child birth, while in United States the lifetime risk is as low as 1 in 84001. HIV/AIDS statistics tell an equally disturbing story of dis- parity. In parts of Africa, over 35% of the adult population — 1 in 3 adults — is infected with HIV 2. The number of women contracting the disease is also on the rise.

  • The impact that physical and psychological violence have on the health of an older person is exacerbated by the ageing process and diseases of old age. It is more difficult for the elderly to leave an abusive relationship or to make correct decisions because of the physical and cognitive impairments that usually come with old age. In some places, kinship obligations and the use of the extended family network to resolve difficulties may also lessen the ability of older people, particularly women, to escape from dangerous situations.

  • Hence, tourism marketing should not only be regarded as a tool for attracting more visitors to a region, as it has been the case for most destinations. Instead, tourism marketing should operate as a mechanism to facilitate regional development objectives and to rationalise the provision of tourism in order to ensure that the strategic objectives of destinations are achieved. Tourism marketing should also ensure equitable returns-on-resources-utilised for the production and delivery of tourism products, as well as the regeneration of these resources.

  • A person who had the cancer and died 10 years later of the cancer would contribute an event, a death due to the cancer, having also contributed 10 person-years of survival time. A 90 % cancer specific survival at 10 years would mean that 90 % of patients had not died from their cancer, while 10 % had died from their cancer (Kaplan, 1958). Calculation of cause-specific survival is especially important when studying diseases with a favorable prognosis, as is the case at hand, where the patients live long enough to be exposed to other causes of death....

  • Article 87 of the Constitution of the Republic of Poland mentions – among the universally binding legislation – also ratifi ed international conventions/agreements.

  • In addition McQueen and Vorkink (2004) are able to reproduce GARCH volatility using a preference-based model with time-varying sensitivity to news. In a related paper, Vanden (2005) develops a model where the representative agent exhibits a utility function with several risk aversion regimes, which in equilibrium leads to volatility regimes and volatility clustering.

  • Normal cells are cohesive in nature but exfoliated when they attain maturation. During malignant conditions or during infection, the exfoliation becomes exaggerated and the epithelial cells show variation in morphology. Such exfoliated cells, when collected and appropriately stained, give information on the living epithelium from which they are derived. These characteristic cellular and nuclear appearances in cells thrown off from healthy epithelium, differ distinctly from those, derived from inflamed or malignant lesions.

  • Again, however, an appropriate comparisons needs to take account of the fact that the SEC took place four years later and the process of cohort succession would affect results in the same way as was noted for literacy with respect to comparisons with the census. Thus when DHS results are calculated for persons aged 56 and older (who would be 60 and older in 2004) and limited to the provinces covered by the SEC sample, the percentages who ever attended school are reasonably similar in the two sources. Overall the comparison of basic demographic characteristics from the 2004...

  • Imagine. It’s 6:25 p.m. and you’ve just wrapped up a meeting. You still have several items on your “must-do” list before you can call it a night and a 25-minute commute that used to take as long as 90 minutes in the bad old days of rush-hour traffic. But no worries today. You flick open an app on your phone and request a pick-up at the office; a text confirmation comes back and a few minutes later a car pulls up. “Home,” you say, as you launch a call to your client in Shanghai. The car slips easily into the...

  • Bonfand borrows it from the philosopher Jean-Luc Marion (one of the most important thinkers of the French new wave in phenomenology), as particularly developed in In Excess: Studies on Saturated Phenomena, 2002 (originally published as: De surcroît. Etudes sur les phénomènes saturées, 2001). In Marion’s phenomenology of giveness, the saturated phenomenon refers to a kind of extreme phenomena which confront the perception and the condition of phenomenality to its limits.

  • In the end, I curled up on a bench in Peel Park, hidden under a rattly newspaper, and slept for what felt like ten seconds before a PCSO woke me up with a rough shake and a bright light in my eyes and sent me back to wander the streets. It was coming on dawn then, and I had a deep chill in my bones, and a drip of snot that replaced itself on the tip of my nose every time I wiped it off on my sleeve. I felt like a proper ruin and misery-guts when I finally dragged my arse back home, stuck...

  • While wood and to some extent charcoal are the most common solid fuels used in developing countries, China and Mongolia have high household prevalence of coal, especially for heating in open portable space heaters, some with and some without chimney. Mestl et al. (2006), based on data from the China 2000 Population Census, report that about 60 percent of rural households used biomass as primary cooking fuel. Nearly 30 percent of rural households used coal as the primary fuel. Mestl et al model annual average population weighted exposure (PWE) to indoor air pollution by...
