Recurrent thromboembolism in pregnancy and puerperium. Is there a need for thromboprophylaxis?

By sending a questionnaire (response rate 93%) to 321 women with a history of venous thromboembolism and previous coagulation tests, 72 patients were identified who had a total of 87 pregnancies after the thromboembolic episode. The main aim of the study was to analyze the influence of prophylaxis during pregnancy and delivery on the development of further thromboembolic complications. During preg

Percutaneous fine-needle aspiration cytology in the diagnosis and management of liver tumours

BACKGROUND: The aim of the study was to investigate the value of percutaneous fine-needle aspiration cytology (FNAC) in the diagnosis and management of liver tumours. METHODS: FNAC followed by histopathological examination was carried out in 216 patients with suspected liver tumours. The final diagnosis was primary liver cancer in 106, colorectal metastases in 51, non-colorectal metastases in 46,

Persistent organic pollutants in river food webs: influence of trophic position and degree of heterotrophy

We investigated how the degree of autotrophy/heterotrophy and organism trophic position influenced the bioaccumulation of polychlorinated biphenyls (PCBs) in 10 benthic river food webs consisting of terrestrial detritus, periphyton, invertebrates, and age-0 brown trout (Salmo trutta) in southern Sweden. Concentrations of PCBs increased with trophic position, estimated from delta(15)N and delta(13)

Electrical properties and logic function of multibranch junction structures

We report on room-temperature electrical measurements of multibranch junction (MBJ) devices made from a semiconductor heterostructure. We show that the MBJ devices exhibit an interesting electrical property. If the voltage output at one branch is measured as a function of the voltages inputs to all the other branches, the output voltage is determined predominately by the most negative, or the lowe

Reduced colonization of newborns with group B streptococci following washing of the birth canal with chlorhexidine

Possible measures for prevention of neonatal group B streptococcal (GBS) septicemia include active or passiv immunoprophylaxis and administration of penicillin to mothers and infants. In a previous study we have found GBS to be extremely sensitive to chlorhexidine. Furthermore vaginal washing with chlorhexidine diminished the recovery of GBS from parturients. In order to study the effect of chlorh

Cartilage induction by controlled mechanical stimulation in vivo

To study mechanical control of tissue differentiation, we designed a new version of the previously described bone conduction chamber. The bone conduction chamber consists of a cylindrical titanium chamber for implantation in the rat tibia. It has tissue ingrowth openings at one end, located subcortically, and the other end protrudes into the subcutis. The newly developed load chamber has a mobile

Elevated atmospheric CO2 concentration and diurnal cycle induce changes in lipid composition in Arabidopsis thaliana

Few studies regarding the effects of elevated atmospheric CO2 concentrations on plant lipid metabolism have been carried out. Here, the effects of elevated CO2 concentration on lipid composition in mature seeds and in leaves during the diurnal cycle of Arabidopsis thaliana were investigated. Plants were grown in controlled climate chambers at elevated (800 ppm) and ambient CO2 concentrations. Lipi

Naturally occurring short splice variant of CYLD positively regulates dendritic cell function

Deubiquitination of NF-kappa B members by CYLD is crucial in controlling the magnitude and nature of cell activation. The role of the naturally occurring CYLD splice variant in dendritic cell (DC) function was analyzed using CYLDex7/8 mice, which lack the full-length CYLD (flCYLD) transcript and overexpress the short splice variant (sCYLD). Bone marrow-derived DCs from CYLDex7/8 mice display a hyp

Combining magnets and dielectrics: Crystal chemistry in the BaO-Fe2O3-TiO2 System.

Phases observed in the BaO-Fe2O3-TiO2 system are classified and described in terms of the framework of close-packed {O,Ba/O} layers, with the transition metal atoms either in octahedral (titanium and iron) or in tetrahedral (iron only) sites. The resulting crystal chemistry features new combinations of structural features intermediate between the magnetic barium hexaferrites and the dielectric bar

On Commodification and the Governance of Academic Research

The new prominence given to science for economic growth and industry comes with an increased policy focus on the promotion of commodification and commercialization of academic science. This paper posits that this increased interest in commodification is a new steering mechanism for governing science. This is achieved by first outlining what is meant by the commodification of scientific knowledge t

ELTs, AO wavelengths and science output

A study is presented of the impact on science data from extremely large telescopes of a transformation of wavelength base for optimization of actuator architecture from 2 200 to 1250 nm. From the optical path difference (OPD) data for Euro50, we transform to E-ELT OPDs. We compute the corresponding power spectrum, in which we simulate a higher actuator density via high-pass filtering to convert fr

Enhanced efficiency of industrial-scale anaerobic digestion by the addition of glycosidic enzymes

The results of the action of two glycosidic enzymes added to an anaerobic digester processing mixed wastewater sludge are reported in this paper. The experiment was performed at a continuously operating full-scale wastewater treatment plant during a 6-month period. The addition of the enzyme mixture resulted in improved gas production and dewatering properties. Dewatering experiments, both on enzy
