Reliability of gait performance tests in men and women with hemiparesis after stroke.

Objective: To assess the reliability of 6 gait performance tests in individuals with chronic mild to moderate post-stroke hemiparesis. Design: An intra-rater (between occasions) test-retest reliability study. Subjects: Fifty men and women (mean age 586.4 years) 6–46 months post-stroke. Methods: The Timed “Up & Go” test, the Comfortable and the Fast Gait Speed tests, the Stair Climbing ascend a

Effects of red meat and fiber in high fat diet on activities of sphingomyelinase, ceramidase and caspase-3 in rat colonic mucosa.

Red meat and fiber rich foods are the dietary factors most consistently related to colon carcinogenesis. Although several components in these dietary sources may contribute, the biochemical mechanism by which red meat and fiber affect colorectal carcinogenesis has not yet been established. Sphingomyelin metabolism is a novel signal transduction pathway that may have an impact on colonic tumorigene

Conflicting evidence about long-distance animal navigation

Because of conflicting evidence about several fundamental issues, long-distance animal navigation has yet to be satisfactorily explained. Among the unsolved problems are the nature of genetic spatial control of migration and the relationships between celestial and magnetic compass mechanisms and between different map-related cues in orientation and homing, respectively. In addition, navigation is

Experimental and theoretical studies of lifetimes and transition probabilities for Au II

We report lifetime measurements for three of the 5d(9)6p levels in An II and relativistic multiconfiguration Dirac-Fock (MCDF) calculations of lifetimes and transitions probabilities in this ion. The work was motivated by significant disagreements between previous experimental 5d(9)6p lifetimes, obtained by means of the beam-foil (BF) method and theoretical data based on Hartree-Fock calculations

Main group atoms and dimers studied with a new relativistic ANO basis set

New basis sets of the atomic natural orbital (ANO) type have been developed for the main group and rare gas atoms. The ANO's have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive and negative ions, and the dimer at its equilibrium geometry. Scalar relativistic effects are included through the use of a Douglas-Kroll Hamiltonian. Multico

Effects of natural and sexual selection on adaptive population divergence and premating isolation in a damselfly

The relative strength of different types of directional selection has seldom been compared directly in natural populations. A recent meta-analysis of phenotypic selection studies in natural populations suggested that directional sexual selection may be stronger in magnitude than directional natural selection, although this pattern may have partly been confounded by the different time scales over w

Quality of life of elderly persons with cancer: a 6-month follow-up

The aim of this study was to investigate possible changes in quality of life (QoL) in elderly persons diagnosed with cancer (65 years and above), in relation to age, contact with the health-care system, activities of daily living, hope, social network and support. The investigation points were at time of diagnosis (baseline), and again 3 and 6 months after the diagnosis. The study also aimed to in

Migration patterns and phenotypic differentiation of long-term expanded human neural progenitor cells after transplantation into the adult rat brain.

We have examined long-term growth-factor expanded human neural progenitors following transplantation into the adult rat brain. Cells, obtained from the forebrain of a 9-week old fetus, propagated in the presence of epidermal growth factor, basic fibroblast growth factor, and leukemia inhibitory factor were transplanted into the striatum, subventricular zone (SVZ), and hippocampus. At 14 weeks, imp

Det extraordinäras lockelse : Luffarturistens bilder och upplevelser

Popular Abstract in Swedish ”Luffarturismen” har blivit en populär form av resande. Många svenskar för under en tid - ibland flera månader eller år - en vagabonderande tillvaro på platser långt hemifrån. Resan blir en parentes i vardagen - en extraordinär sfär fylld av förväntningar på äventyret och den äkta upplevelsen. Vad har resenären för bild av det ”Långtbortistan” hon lockas av, och hur skThis dissertation, The Attraction of the Extraordinary - Images and Experiences Among Backpacker Tourists, is a study based on informal interviews with predominantly Swedish independent travellers, as well as observations and documentary analysis of the backpacker subculture. Backpacking is a type of tourism which has been gradually institutionalized. Through the institutionalization of the backpa
