Communicating cancer risk and recommending adequate control programs is central for genetic counseling. Individuals affected by hereditary nonpolyposis colorectal cancer (HNPCC) are at about 80% life-time risk of colorectal cancer and for female carriers 40-60% risk of endometrial cancer and 10-15% risk of ovarian cancer. The perceived risk among mutation carriers may, however, deviate from the ri

The dinoflagellate Peridinium aciculiferum forms blooms underneath the ice in temperate lakes and has previously been shown to have an allelopathic effect on a natural competitor as well as being haemolytic. Hence, we investigated whether P. aciculiferum is allelopathic towards a wide range of different freshwater phytoplankton species. We also tested the hypothesis that nutrient (N and P) deficie

When a spin bias is applied to a two-terminal device, a charge current will be generated. We demonstrate the rectification of such a current by studying spin-dependent transport through a quantum point contact (QPC) modulated by a spin-orbit interaction. When the polarization orientation of the spin bias (which is the spin-quantization axis) is along the transverse direction of the QPC, the two sp

The midbrain periaqueductal gray matter (PAG) integrates the basic responses necessary for survival of individuals and species. Examples are defense behaviors such as fight, flight, and freezing, but also sexual behavior, vocalization, and micturition. To control these behaviors the PAG depends on strong input from more rostrally located limbic structures, as well as from afferent input from the l

Complex tree-like nanostructures with controlled morphology are becoming increasingly important for the development of nanoscale devices. The position of branches on III-V semiconductor nanotrees is determined by the distribution of Au seed particles. Here we report the dependence of the distribution of Au aerosol nanoparticles on nanowires on parameters including distance between wires, particle

Structural best management practices (BMPs) are now commonplace for stormwater management in new suburban developments; however, their installation in older central areas is limited. Here, the effect of disconnecting impervious areas from a combined sewer in favour of a new open stormwater system is investigated. The site, an inner city suburb of Malmo, Sweden, consists of council offices and apar

Dose integration properties were investigated for normoxic polymer gels based on methacrylic acid (nMAG) and acrylamide/ N, N'-methylenebisacrylamide (nPAG). The effect of sequential irradiation was studied for different fractionation schemes and varying amounts of methacrylic acid for the nMAG gels. Magnetic resonance imaging (MRI) was used for read out of the absorbed dose response. The investig

Ordovician conodont specimens resembling Oistodus venustus STAUFFER, 1935 have been reported from many areas. There is increasing evidence, however, that several lineages with homeomorphic conodont elements have erroneously been referred to one and the same species. I have investigated Baltoscandian conodont elements of this kind in order to find out about their origins and phylogenetic relationsh

The valence character of O 1s -> Rydberg excited O-2 is investigated by means of participator Auger decay spectroscopy, performed at selected photon energies across the K-shell resonance region, and by means of partial ion yield x-ray absorption spectroscopy. For several of the excitation energies studied, the authors find substantial sigma(*)((4)Sigma(-)(u),(2)Sigma(-)(u)) valence character being

Diamond-Blackfan anemia (DBA) is a congenital red cell aplasia in which 25% of the patients have a mutation in the ribosomal protein S19 (RPS19) gene. To study effects of RPS19 deficiency in hematopoiesis we transduced CD34(+) umbilical cord blood (CB) and bone marrow (BM) cells with 3 lentiviral vectors expressing small interfering RNA (siRNA) against RPS19 and 1 scrambled control vector. All vec

Male breast cancer is a rare disease and clinical or epidemiological data are available from only a relatively few cases. Nonetheless, both similarities and discrepancies are apparent between breast cancer in men and women. For example, lobular and mucinous carcinomas are seldom seen in men. Tumors in men more often display neuroendocrine differentiation, with an average age at diagnosis ten years

Cyclometalated ruthenium(II) complexes, [Ru II(C~N)(N~N) 2]PF 6 [HC~N=2-phenylpyridine (Hphpy) or 2-(4'-tolyl)pyridine; N~N=2,2'-bipyridine, 1,10-phenanthroline, or 4,4'-dimethyl-2,2'-bipyridine], are rapidly oxidized by H 2O 2 catalyzed by plant peroxidases to the corresponding Ru III species. The commercial isoenzyme C of horseradish peroxidase (HRP-C) and two recently purified peroxidases from

Ever since Dr. Bolia et al. published their paper of intentional subintimal angioplasty more than 20 years ago it have become a more and more used technique in several centres around the world. Its popularities have gained the last 5 years, following a number of publications from various centres in Europe and the USA. After its initial successes in the femoropopliteal segment, the techniques has b

Aim: Predictive equations for estimating body composition from bioelectrical impedance analysis (BIA) among Scandinavian children are lacking. In the present study, equations for estimation of fat-free body mass (FFM) and lean tissue mass (LTM) were developed and cross-validated from BIA using dual-energy X-ray absorptiometry (DXA) as the reference measurement of body composition. Methods: The stu

Numerous studies have identified a role for the innate and adaptive immune response in atherosclerosis; both pro- and antiatherogenic roles for the immune responses have been demonstrated. Common autoantigens against which an immune response has been identified in experimental and human models of atherosclerosis include oxidized low-density lipopoteins, beta2 glycoprotein 1 and heat shock protein
