Cancer is a major cause of human morbidity and mortality, and the risk of developing cancer is about one in three life times. Neuroblastoma is the most common extra-cranial solid tumor among children and arises from early sympathetic nervous system (SNS) cells arrested in their development. Generally, a low tumor cell differentiation correlates to poor prognosis. Solid tumors, like neuroblastoma,

A number of different noble metal catalysts were studied for activity in the preferential oxidation of carbon monoxide in hydrogen-rich streams. The prepared catalysts had an active phase of platinum, palladium, iridium, ruthenium or rhodium impregnated either directly on an aluminia matrix or mounted on nickel or cobalt oxide. The catalysts were studied for activity, but also for the reversed wat

Motivated by applications in high-dimensional settings, we suggest a test of the hypothesis H-0 that two sampled distributions are identical. It is assumed that two independent datasets are drawn from the respective populations, which may be very general. In particular, the distributions may be multivariate or infinite-dimensional, in the latter case representing, for example, the distributions of

More and more countries are now permitting a classification of structural elements with respect to fire exposure to be formulated analytically as an alternative to the internationally preualent method of classification, based on results of standard fire resistance tests. In some countries, the authorities also have taken the next step to approve a general practical application of a direct analytic

A successful model of liaison between the primary and secondary (hospital) levels of health care entails improved co-operation between hospital doctors and general practitioners (GPs). Since its introduction in Denmark in 1991, this approach has been adopted in Sweden and, to a lesser extent, in Norway. Important principles of the model include: 1) both at the primary and secondary level, responsi

Discussion and debate regarding decision-making that is 'in the best interest of the child' and that also considers the child's voice in these decisions have increased in recent years. A study was undertaken to identify everyday situations in medical and nursing care in which children had been allowed to have a voice or been denied the right. Twenty-six hospitalized children, ages 6 to 17 years, a

In a study of a Swedish emergency clinic, it was found that patients' waiting produced different forms of hostile interaction between staff members and patients. A patient's hostility was interpreted as being not only a result of waiting per se but also-and predominantly-due to some features inherent in the relevant situation: the semiotics of space and the organization of waiting. Emotional and i

In a consecutive and unselected series of 178 cases of carcinoma in situ of the breast (CIS), comprising both ductal (DCIS) and lobular type (LCIS), and a series of 48 cases of invasive carcinoma (IC) with predominance of DCIS, the association between histopathology, immunohistochemical markers (ER, PgR, MIB-1, c-erbB-2, and p53), and DNA ploidy was investigated, in order to discriminate biologica

The manual describes the use of Jitterbug, a Matlab toolbox for analysis of real-time control performance. The tool facilitates the computation of a quadratic performance index for a linear control system under various timing conditions.

Neutral B meson oscillations in the B-s(0) - , and B-d(0) - systems were studied using a sample of about 4.0 million hadronic Z decays recorded by the DELPHI detector between 1992 and 2000. Events with a high transverse momentum lepton were removed and a sample of 770 k events with an inclusively reconstructed vertex was selected. The mass difference between the two physical states in the B-d(0)
