The day-to-day variation in oxygen consumption ((V) over dot O-2) during ergometer cycling by 20 healthy adolescents, 10 females and 10 males, was measured using indirect calorimetry. The two sets of measurements were performed on two consecutive days. Great care was taken to minimize possible disturbing factors. Cycling started at 50 and 100 W for female and male adolescents, respectively. The lo

77 species of Hieraciurn sect Hieracium known from the province of Ostergotland are treated with standardized descriptions, determination keys and illustrations. Sixty-one species are indigenous, two of these are endemic, and 16 have been introduced accidentally with grass-seed from central Europe. Compared to other south-Swedish provinces, the Hieracium-flora of Ostergotland is very rich in speci

The time-dependent traveling salesman problem (TDTSP) is a variant of TSP with time-dependent edge costs. We study some restrictions of TDTSP where the number of edge cost changes are limited. We find competitive ratios for online versions of TDTSP. From these we derive polynomial time approximation algorithms for graphs with edge costs one and two. In addition, we present an approximation algorit

Bactericidal/permeability-inereasing protein (BPI) neutralizes the proinflammatory effects of lipopolysaccharide and is of potential clinical use in the treatment of fulminant Gram-negative infections. BPI is a cationic protein with antibacterial activity stored in azurophil (primary) granules of neutrophil granulocytes. However, the absence of BPI in patients with specific granule deficiency indi

Five parkinsonian patients were transplanted bilaterally into the putamen and caudate nucleus with human embryonic mesencephalic tissue from between seven and nine donors. To increase graft survival, the lipid peroxidation inhibitor tirilazad mesylate was administered to the tissue before implantation and intravenously to the patients for 3 days thereafter. During the second postoperative year, th

Accurate identification of lymph node involvement is critical for successful treatment of patients with colorectal carcinoma ( CRC). Real- time quantitative RT - PCR with a specific probe and RNA copy standard for biomarker mRNA has proven very powerful for detection of disseminated tumour cells. Which properties of biomarker mRNAs are important for identification of disseminated CRC cells? Seven

Factors affecting phase separation in water-salt solutions of polyelectrolyte complexes (PECs), formed by DNA and integral or pendant polycations with a quaternary amino group in every monomer unit, have been studied. When no salt was added, quantitative DNA precipitation occurred at a stoichiometric charge ratio, = [+]/[-] 1. In DNA mixtures with poly(N,N'-dimethyldiallylammonium chloride) (PDMDA

In nonequimolar solutions of a cationic and an anionic surfactant, vesicles bearing a net charge can be spontaneously formed and apparently exist as thermodynamically stable aggregates. These vesicles can associate strongly with polymers in solution by means of hydrophobic and/or electrostatic interactions. In the current work, we have investigated the rheological and microstructural properties of

Polystyrene (PS) blends containing a dispersed phase of either polyamide-6 (PA-6) or polyamide-12 (PA-12) were compatibilized by additions of 1, 3, or 5 wt % poly(styrene-graft-ethylene oxide). The graft copolymers were found to have a stabilizing effect on the domain sizes. Weight average radii of PA-6 domains in compression molded samples were reduced by a factor of 5 with 3 wt % graft copolymer

In making societal decisions concerning hazards with potentially disastrous consequences it is important to have soundly based knowledge of how people evaluate the seriousness of disasters. In the present study a group of students evaluated the seriousness of disasters described in terms of four basic attributes (and their ranges): number of fatalities (0-1000), number of serious injuries (0-4000)

Although scholars have long been aware of syntactical difficulties in Rom 1.1315, few have approached the problem by challenging the established punctuation. Readings of the text by some earlier interpreters, e.g. Origen of Alexandria, indicate that there may be good reasons to do so. In this article it is argued that current readings of Rom 1.1315 are based on inaccurate punctuation and syntax. A

It is proposed in this paper that many geometrical optical illusions, as well as illusory patterns due to motion signals in line drawings. are due to the statistics of visual computations. The interpretation of image patterns is preceded by a step where image features such as lines, intersections of lines, or local image movement must be derived. However, there are many sources of noise or uncerta

Objective: To collect data on the practices of molecular genetic testing (MGT) laboratories for the development of national and international policies for quality assurance (QA). Methods: A web-based survey of MGT laboratory directors (n = 827; response rate 63%) in 18 countries on 3 continents. QA and reporting indices were developed and calculated for each responding laboratory. Results: Laborat

The rat brain-derived neurotrophic factor (BDNF) gene consists of four short 5'-exons linked to separate promoters and one 3'-exon encoding the mature BDNF protein. Using in situ hybridization we demonstrate here that kindling-induced seizures, cerebral ischaemia and insulin-induced hypoglycaemic coma increase BDNF mRNA levels through insult- and region-specific usage of three promoters within the

Transverse momentum spectra of electrons from Au+Au collisions at roots(NN) = 130 GeV have been measured at midrapidity by the PHENIX experiment at the Relativistic Heavy Ion Collider. The spectra show an excess above the background from photon conversions and light hadron decays. The electron signal is consistent with that expected from semileptonic decays of charm. The yield of the electron sign

Antisocial personality disorder (ASPD) is one of the most common co-occurring disorders in substance abusers, characterized among other things by a high propensity for criminal actions. A cohort of 125 substance abusers were followed in a longitudinal design. Patients were diagnosed with ASPD at an index treatment episode, interviewed at five-year follow-up, and followed-up through the Swedish cri
