Introduction: Impacted morselized bone allograft is thought to be remodeled to a great extent. We have previously shown that load-bearing increases the remodeling of impacted morselized bone allografts in a rabbit knee prosthesis model. Bone Morphogenic Proteins (BMPs) also stimulate bone formation and bone allograft remodeling. In this study, our aim was to determine whether it was possible to in

Some raw material characteristics were evaluated in three apple varieties cultivated in Southern Sweden, namely Kim, Mutsu and Jonagold. The study was undertaken to collect information in order to identify the effects of initial tissue properties on mass transport phenomena in general, and osmotic processing responses in particular. The texture profile analysis revealed cortex anisotropy of the th

The ion photon emission microscope, or IPEM, is the first device that allows scientists to microscopically study the effects of single ions in air on semiconductors, microchips and even biological cells without having to focus the beam. Reported here is a prototype, the size of a conventional optical microscope, developed at Sandia. The alpha-IPEM, that employs alpha particles from a radioactive s

Objective: To compare 5% albumin, 6% dextran 70, 3.5% gelatin, 6% hydroxyethyl starch 130/0.4, and saline regarding their plasma volume expanding effect after a surgical skeletal muscle trauma and their simultaneous effects on transvascular fluid exchange in skeletal muscle. Design: Controlled, prospective, randomized laboratory study. Setting: University research laboratory. Subjects: Thirty-six

This paper critically reviews reconstructions of cultural development in prehistoric Amazonia and argues for the primacy of regional and interregional exchange in generating the complex distributions of ethno-linguistic identities traced by linguists and archaeologists in the area. This approach requires an explicit abandonment of notions of migrating "peoples" in favor of modern anthropological u

Field investigations were performed in semiarid Tunisia to investigate spatial variability of preferential pathways in catchment- and plot-scales. A rainfall simulator with dye was used to simulate effects of a 20-year rainstorm. After infiltration into six one-meter square plots, vertical 2.5-cm thick soil sections were excavated, and dye penetrations were photographed, The results show that diff

Background Despite high incidence of ankle fractures in the elderly, studies evaluating outcome and impact of quality of life in this age group specifically are sparse. The aim of this study was to evaluate outcome and quality of life 6 and 12 months after injury in patients 65 years or older who had been operated on due to an ankle fracture. Methods Sixty patients 65 years or older were invited

Two-pulse photon-echo measurements on the 0.1 at. % Pr3+:YAlO3 H-3(4)-D-1(2) transition suggest that the relaxation time depends on the density of excited states created by the excitation pulses. The dependence of the relaxation time on the intensity of each excitation pulse shows that our results are inconsistent with instantaneous spectral diffusion, a model often invoked in this type of experim

Embryonic stein (ES) cells are derived from the inner cell mass of the blastocyst and can be cultured as three-dimensional embryoid bodies (EBs) in which embryonic pregastrulation stages are faithfully mimicked. Fibroblast growth factor receptors (mainly FGFR2) are involved in the first differentiation events during early mammalian embryogenesis. It has been demonstrated that the presence of FGFR2

Redan romarna anlade fältsjukhus i natursköna områden för att rehabiliteringen skulle fungera bra. Även i modern tid har man uppfört sjukhus i parkmiljöer i syfte att förbättra hälsan hos patienterna. Sjukhusen har gärna utformats så att det är lätt att ta sig ut till de omgivande markerna, fönstren vetter utåt och trädgårdar planeras för att ge patienterna kontakt med naturmiljön. I slutet av 180

The neutron-deficient nucleus La-123 was studied via the Mo-92(Ca-40,2ap) reaction at a beam energy of 184 MeV. Previously known bands were extended to a much higher spin, and in two cases the structures are now observed near 40 (h) over bar. In addition, three new sequences were identified and linked into previously known bands. The lowest (pi,alpha)=(+,-1/2) structure displays characteristics si

The authors examined Swedish judges', lay judges', and police officers' beliefs about factors that may complicate or facilitate children's reports of sexual abuse. Participants (N = 562) rated potential complicating and facilitating factors and freely reported which criteria they considered important when assessing the reliability of child witnesses. The groups had similar opinions regarding which

The effect of long-term ethanol exposure on muscarinic receptors was investigated in human neuroblastoma SH-SY5Y cells. Exposure to 100 mM ethanol for 4 days enhanced both peak and steady-state levels of carbachol-stimulated inositol 1,4,5-bisphosphate increase. An ethanol concentration of 50 mM was sufficient for an enhancement of this event. The carbachol-stimulated decrease in [3H]inositol-labe
