BACKGROUND: The method for red marrow dosimetry in radioimmunotherapy, in the absence of specific activity uptake in red marrow, is based on the activity measured in the blood or plasma. The activity concentration ratio of red marrow to blood is then assumed to be constant. The aim of the current study was to determine whether this ratio varies with time after injection. METHODS: Measurements were

Most studies of social polygyny in birds have examined male provisioning on the basis of the number of feeding visits. This may be misleading if males compensate for infrequent visits by bringing larger prey at each visit. We investigated nestling provisioning in the socially polygynous great reed warbler, Acrocephalus arundinaceus, in south Central Sweden in 1996-1997. We collected data on rare o

Inhibitors formed during wood hydrolysis constitute a major problem in fermenting dilute-acid hydrolysates. By applying a fed-batch technique, the levels of inhibitory compounds may be held low, enabling high ethanol productivity. In this study, a previously developed fed-batch strategy was modified and implemented for use in pilot development unit (PDU) scale. The rate of total gas formation, mea

Molybdenum complexes of 3,6-di-tert-butylcatechol have been prepared from the reaction between [Mo(CO)6] and 3,6-di-tert-butyl-1,2-benzoquinone. A putative "[MoO(3,6-DBCat)2]" monomer is assumed to form initially by reaction with trace quantities of oxygen. Condensation of the reaction mixture leads to the formation of oligomeric products, including the [{MoO(3,6-DBCat)2}4] chiral square isolated

given depth, including submerged macrophytes and associated invertebrates. The sampler is a tong-shaped instrument consisting of two metal rods connected by a flexible joint. At the end of each arm is a metal cylinder (diameter 10 cm); one end of the cylinder has a sharpened edge and the other is equipped with a net. Powerful metal springs force the cylinders together at high speed, and macrophyte

Abstract in UndeterminedBackground: Individuals with aphasia often experience difficulties in writing. Word processors with a spell checker and a grammar checker can compensate for some of the writing difficulties associated with aphasia. Aims: To determine if writing difficulties associated with aphasia may be reduced by the use of a computerised writing aid when training patients. Methods Proced

The human polymnaviruses JC virus (JCV) and BK virus (BKV) are oncogenic in experimental systems and commonly infect humans. JCV DNA has been reported to be present in human colon mucosa and in colorectal cancers. To investigate whether the risk for colorectal cancer is associated with JCV or BKV infection, we performed a case-control study nested in the Janus biobank, a cohort of 330,000 healthy

The Dahra field site in Senegal, West Africa, was established in 2002 to monitor ecosystem properties of semiarid savanna grassland and their responses to climatic and environmental change. This article describes the environment and the ecosystem properties of the site using a unique set of in situ data. The studied variables include hydroclimatic variables, species composition, albedo, normalized

The combination of glucagon and glucagon-like peptide-1 (GLP-1) has been suggested as an approach to target obesity, since the two hormones have complementary action on body weight. We examined whether complementary action of the two hormones also exist on insulin secretion. Female C57BL/6 mice were injected intravenously with glucose with or without GLP-1, glucagon or the combination of GLP-1 and

This paper describes a longitudinal, collaborative case study, made in the framework of the project Students' Ownership of Learning (SOL) during one academic year with one vocal teacher and two female students. The aim of the study was to relate the interaction between the teacher's and the students' intentions and expectations to the institutional level as well as to the rules and 'real-life' pra

Gender stereotypes describe women as communal and men as agentic. Laboratory-based research (Rudman & Glick, 1999, 2001) suggests that trying to disconfirm such descriptive gender stereotypes (e.g., women self-promoting their agency), entails the risk of hiring discrimination due to violation of prescriptive gender stereotypes: a backlash. To examine whether backlash occurs when applying for r

Experience-dependent alterations in the human brain's white-matter microstructure occur in early adulthood, but it is unknown whether such plasticity extends throughout life. We used cognitive training, diffusion-tensor imaging (DTI), and structural MRI to investigate plasticity of the white-matter tracts that connect the left and right hemisphere of the frontal lobes. Over a period of about 180 d

We calculate next-to-leading order (NLO) QCD corrections to electroweak Higgs boson plus three jet production. Both vector boson fusion (VBF) and Higgs-strahlung type contributions are included along with all interferences. The calculation is implemented within the MATCHBOX NLO framework of the HERWIG++ event generator.

Purpose: The purpose of this study was to assess the accessibility to public buildings for wheelchair users in Al Ain, the fourth largest city of the United Arab Emirates. Method: Data were collected at 17 buildings, randomly chosen using the local telephone book as source. The instrument used was a survey form covering eight accessibility areas: parking, ramps, entrances, accessible routes, toile

Objective. To determine whether psychosocial factors, chronic diseases, and common geriatric problems are associated with poor physical function 3 years after primary total hip replacement (THR). Methods. We studied a sample of Medicare recipients in Ohio, Pennsylvania, and Colorado (n = 922) who underwent primary THR in 1995 (mean +/- SD age 73.1 +/- 5.6 years, 32% men). Participants completed a

Protein kinase B (PKB)/Akt has been strongly implicated in the insulin-dependent stimulation of GLUT4 translocation and glucose transport in skeletal muscle and fat cells. Recently an allosteric inhibitor of PKB (Akti) that selectively targets PKB alpha and -beta was reported, but as yet its precise mechanism of action or ability to suppress key insulin-regulated events such as glucose and amino a

Study Design. A randomized controlled comparative trial with an 8-month follow-up period was conducted. Objective. To compare the effect of the McKenzie treatment method with that of intensive dynamic strengthening training in patients with subacute of chronic low back pain. Summary of Backround Data. Randomized studies indicate that the efficacy of the McKenzie method in the treatment of patients

We investigated the species richness of vascular plants at the scale of 5 3 5 km in the Swedish province of Harjedalen, and the relationship between richness and environment. Environmental variables included geographical, altitudinal, topographical, bedrock, soil type, and land-cover descriptors. The species richness was subdivided into groups of species with similar life-form, i.e. trees, dwarf s

The basic precondition for color vision is the presence of at least two receptor types with different spectral sensitivities. The sensitivity of a receptor is mostly defined by the opsin-based visual pigment expressed in it. We show here, through behavioral experiments, that the nymphalid butterfly Heliconius erato, although it expresses short and medium wavelength opsins and only one long wavelen
