It is unclear whether thromboprophylaxis produces a consistent risk reduction in different subgroups of medical patients at risk from venous thromboembolism. We performed a retrospective, post hoc analysis of 3706 patients enrolled in the PREVENT study. Patients were at least 40 years old with an acute medical condition requiring hospitalization for at least 4 days and had no more than 3 days of i

Stable isotopes of nitrogen (delta(15) N) and carbon (delta C-13) were measured for Atlantic salmon Salmo salar and their intestinal cestode, Eubothrium crassum, sharing the same diet. Atlantic salmon muscle tissues were enriched in N-15 and depleted in C-13 compared to their prey (sprat Sprattles sprattus sprattus) and their intestinal cestode. There was no significant difference in delta N-15 or

Structural manifestations of Alzheimer's disease (AD) including neuronal loss were investigated in 12 cases of AD and in 10 healthy age-matched controls, with focus on the cerebellum. Linear Purkinje cell (PC) density was measured in the vermis and cerebellar hemispheres. Neurons were also counted in the inferior olivary nucleus. In vermis of the AD cases, the mean PC number was significantly lowe

We describe the design and implementation of a robotic solution to automate the acquisition of gel images. The soft- and hardware aspects are outlined together with the various safety aspects that need to be addressed.

onthly averages of ecosystem respiration (ER), gross primary production (GPP) and net ecosystem exchange (NEE) over Scandinavian forest sites were estimated using regression models driven by air temperature (AT), absorbed photosynthetically active radiation (APAR) and vegetation indices. The models were constructed and evaluated using satellite data from Terra/MODIS and measured data collected at

1. Agri-environmental schemes (AES) are commonly adopted in Europe to reduce the loss of farmland biodiversity. These schemes have, however, been criticized as not fulfilling this goal, partly because their effectiveness is thought to differ depending on external factors such as landscape heterogeneity, the focal organism and scale of application. 2. We used one AES, organic farming, as a landscap

This study investigated whether human postural stability and adaptation were affected by sleep deprivation and the relationship between motor performance and subjective scores of sleepiness (visuo-anlogue sleepiness scores, VAS). Postural stability and subjective sleepiness were examined in 18 healthy subjects (mean age 23.8 years) following 24 and 36 h of continued wakefulness, ensured by portabl

The preoperative fine-needle aspiration cytology (FNAC) diagnoses in 116 surgically excised neurilemomas were reviewed and compared with the corresponding histopathologic diagnoses made on surgical specimens and with clinical data. In addition, the utility of adjunctive techniques was analyzed and other spindle-cell lesions in the differential diagnoses were discussed. An unequivocal, benign diagn

Urokinase plasminogen activator (uPA) is involved in the activation of different proteases which participate in the degradation of extracellular matrix, thereby enhancing the invasive capacity of tumour cells. uPA has been shown to be of prognostic importance in breast cancer. We have analysed uPA with a new luminometric immunoassay (LIA), applicable in cytosol samples routinely used for oestrogen

Twenty-four children (aged 5 months to 18 years) who were admitted to a university hospital were observed for a total of 135 hours with the aim of describing their degree of participation in decisions concerning their own care. Grading of their participation was made by using a 5-point scale. An assessment was also made of what was considered as optimal participation in each situation. The results

Postural adaptability and responses elicited by vibratory stimulation to the calf muscles recorded on a force platform with eyes open or closed were analyzed in 39 patients suffering from Postural Phobic Vertigo (PPV) (17 men and 22 women, mean age 49 years) and 24 healthy subjects (14 men, 10 women, mean age 38 years). The vibration induced increased body sway in both groups, but the adaptation p

We have studied the differentiation of striatal projection neurons in co-culture with expanded glia from different regions of the embryonic mouse telencephalon. Our results show that when striatal progenitors are cultured on glia derived from the same region as they originate (i.e. the lateral ganglionic eminence), the neurons formed exhibit long processes. This is not the case when the cells are

The aim of this study was to determine the number of tibialis anterior biopsy samples and muscle fibers required to estimate the capillary supply of individual muscle fibers (C:F-i). C:F-i was calculated for 25 type 1 fibers in each of 8 images from 3 biopsies of 5 young healthy individuals. Sequential estimation analysis indicated that 50 fibers from one biopsy are sufficient to characterize the

A new mechanistic model of drug release during the lag phase from coated pellets undergoing cracking in the coating due to the hydrostatic pressure built up inside the pellet has been developed. The model describes dynamically all the main release processes occurring during the lag phase in pellets coated with a semi-permeable membrane, i.e. the influx of solvent driven by the difference in osmoti

Transition probabilities and radiative lifetimes have been obtained for 45 transitions of Re II using a combination of radiative lifetime values obtained with the laser-induced fluorescence technique ( seven levels) and theoretical branching fractions. This new set of results, concerning ultraviolet and visible lines, will be useful in the future for investigating the composition of chemically pec

The gas phase hydrodeoxygenation of a series of aromatic alcohols, aldehydes and acids has been examined over Ni/SiO2. Compensation behaviour is established with an isokinetic temperature (518 +/- A 21 K) that is consistent with with the point of intersection of the Arrhenius lines. This is accounted for using the Selective Energy Transfer model that is based on resonance between the catalytic Ni-

Abstract in French La sédation des patients neurochirurgicaux fait appel le plus souvent à une association hypnotique-analgésique. Leurs effets sur l'hémodynamique et le métabolisme cérébraux sont l'un des critères qui président au choix des produits. Les analgésiques utilisés seuls, ont peu d'effets sur le flux sanguin cérébral et la CMRO2. Certaines données de la littérature attribuent aux analg

Software inspections are regarded as an important technique to detect faults throughout the software development process. The individual preparation phase of software inspections has enlarged its focus from only comprehension to also include fault searching. Hence, reading techniques to support the reviewers on fault detection are needed. Usage-based reading (UBR) is a reading technique, which foc
