Dissecting karyotypic patterns in colorectal tumors: two distinct but overlapping pathways in the adenoma-carcinoma transition.
More than 500 colorectal tumors with clonal chromosomal abnormalities have been reported. Although the pattern of aberrations is nonrandom, no specific primary or secondary karyotypic abnormality has been identified. Also, the chronological order in which the aberrations appear during disease progression is not well known. One reason why our understanding of the cytogenetic evolution is unclear is
Use of morphology to characterize and manage common adnexal masses.
The use of grey-scale ultrasound morphology to characterize a pelvic mass may also be called ‘pattern recognition’. The grey-scale ultrasound image provides us with the same information as that obtained by the surgeon or pathologist when he or she cuts a surgical specimen to see what it looks like inside. Many pelvic masses have such a typical macroscopic appearance that a fairly confident diagnos
Changes of cartilage and bone markers after intraarticular glucocorticoid treatment with and without postinjection rest in patients with rheumatoid arthritis
Background: Joint immobilisation improves the therapeutic effect of intra-articular glucocorticoid injection for knee synovitis. This may be due to retarded steroid resorption by immobilisation, a procedure that also could influence cartilage and bone metabolism. Objective: To evaluate changes in cartilage and bone turnover after intra-articular glucocorticoid treatment for knee synovitis with and
Cell chromatography: Separation of different microbial cells using IMAC supermacroporous monolithic columns
Supermacroporous monolithic columns with CU2+-IDA ligands have been successfully used for chromatographic separation of different types of microbial cells. The bed of monolithic matrix is formed by a cryogel of poly(acrylamide) cross-linked with methylenebis(acrylamide) and has a network of large (10- 100 mu m) interconnected pores allowing unhindered passage of whole cells through the plain cryog
Rotational and Single-particle Structures in 83Zr
The band structure of Zr-83 has been investigated using the Daresbury recoil separator and TESSA array with 20 Compton suppressed Ge detectors and the reaction Si-28 (Ni-58, 2pn) at 195 MeV. DCO ratios have been used to make many new spin assignments. The three known rotational bands have been extended up to the onset of the five quasiparticle bands. On the basis of the 21/2+, 23/2+ and 25/2+ yras
A novel mutation in the β-protein coding region of the amyloid β-protein precursor (APP) gene
A novel mutation, a C to T transition at base pair 2124 in exon 17 of the amyloid beta-protein precursor (APP) gene, has been identified by direct sequencing of amplified DNA from two Alzheimer's disease (AD) patients. A simple oligonucleotide-hybridization procedure was developed to allow population studies of this DNA variation. The mutation, which is silent at the protein level, was present in
Biostratigraphical and palaeoecological significance of graptolites, trilobites and conodonts in the Middle-Upper Ordovician Anderso Shale: an unusual 'mixed facies' deposit in Jamtland, central Sweden
Although only about 20 m thick, the Anderso Shale contains one of the most diverse, if not the most diverse, late Middle-early Late Ordovician faunas known in Baltoscandia. It includes more than 20 trilobite species, more than 20 species of other shelly fossils, about 10 graptolite species, and about 20 conodont species. Based on its lithology, its geographical position near the foreland basin mar

It's Our Time to 'Chop': Do Elections in Africa Feed Neopatrimonialism rather than Counter-Act it?
This article addresses the concern that democratization may contribute to the reproduction of neo-patrimonialism, rather than to counteract it. The article reports the result of a survey among members of parliament in Ghana regarding their election campaigns. Total spending, sources of funds, and their usage are analysed in the context of the consolidation of liberal democracy. The survey results
Informal investors as entrepreneurs – the development of an entrepreneurial career
Informal investors have proved to be highly valuable for the growth of the firms in which they have invested. Therefore, it is important to understand what motivates potential informal investors to make their initial investment as well as how already active investors develop their entrepreneurial careers. Such an understanding may prove helpful in directing efforts to locate and attract potential
The Power of Elections : Democratic Participation, Competition and Legitimacy in Africa
Popular Abstract in Swedish Baserat på ett nytt data material bestående av observationer på 16 variabler i 232 val i Afrika, görs tre olika analyser. Först avvisas ett antal etablerade hypoteser om nutida Afrikansk politik och demokratisering. Sedan påvisas valens självförstärkande och självförbättrande kraft med hänvisning till institutioners interna logik och strukturering av aktörers incitamenThis book is about elections and democracy in newly democratizing countries. Building on a new data set of 5,568 observations in 232 elections, it provides evidence elections have a casual impact on improving the quality of democracy in Africa in more than one way. The study demonstrates multiparty elections do not signal the end of transitions to democracy but rather foster liberalization and hav

Optical properties, durability, and system aspects of a new aluminium-polymer-laminated steel reflector for solar concentrators
A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test
Amplification of 12q13 and 12q15 sequences in a sclerosing epithelioid fibrosarcoma
Sclerosing epithelioid fibrosarcoma (SEF) is a recently described entity. It is a low-grade sarcoma that occurs primarily in the deep soft tissues of the extremities of adults. It may histologically simulate benign lesions such as fibroma and myxoma or malignancies such as sclerosing carcinoma and lymphoma, extraskeletal myxoid chondrosarcoma, clear cell sarcoma of tendons and aponeuroses, and syn
