Survival and long distance migration of brain-derived precursor cells transplanted to adult rat retina

Neural precursor cells transplanted to adult retina can integrate into the host. This is especially true when the neural precursor rat cell line RN33B is used. This cell line carries the reporter genes LacZ and green fluorescent protein (GFP). In grafted rat eyes, RN33B cells are localized from one eccentricity to the other of the host retina. In the present study, whole-mounted retinas were analy

Mitogenic effects of ATP on vascular smooth muscle cells vs. other growth factors and sympathetic cotransmitters

The sympathetic nervous system has been shown to exert a trophic influence on vascular smooth muscle cells (VSMC). Therefore, we studied the growth-regulating effects of the sympathetic cotransmitters ATP, neuropeptide Y (NPY), and norepinephrine (NE). ATP in concentrations of 1-100 microM greatly increased the incorporation of [3H]thymidine in VSMC from rat aorta and vena cava. ATP also increased

Natural history of patients with unoperated atherosclerotic carotid artery disease--results from a retrospective study

The natural history of carotid artery disease was studied in a retrospective study of 609 angiograms performed during 1969-1979 on patients who had subsequently not been operated on. The indication for angiography differed, but was aimed at clarifying suspected cerebrovascular events. 578 patients could be followed-up after a median time of 10.4 years (0-22). The median survival time after angiogr

Left ventricular heart failure model for testing cardiac assist devices

During the development of a new circulatory support system, we have used different animal models with and without heart failure for hemodynamic testing. As the normally functioning heart does not always allow for proper evaluation of a circulatory support system, a good and adjustable animal heart failure model is needed. The aim of the study was to develop a left ventricular failure model in calv

Some chroococcalean and oscillatorialean Cyanoprokaryotes from southern African lakes, ponds and pools

This article is the first part (Chroococcales and Oscillatoriales) of a study of little known planktic and metaphytic cyanoprokaryotes (cyanophytes, cyanobacteria) from ponds, lakes and water reservoirs in southern Africa. Thirty-three species were observed, of which 24 are presented with comments. Ten new species are defined, and one species, originally described as a taxonomic form, is recombine

Geographical variation of mortality from cardiovascular diseases. The Project 'Myocardial Infarction in mid-Sweden'

In this study, the geographical variation of the mortality rate in mid-Sweden was studied. Data on mortality from all causes and mortality from cardiovascular diseases, cerebrovascular diseases, ischaemic heart disease (IHD) and non-cardiovascular diseases for men and women 45-74 years of age living in 76 communities in mid-Sweden were obtained from the National Bureau of Statistics. After age sta

Animism, fetishism, and objectivism as strategies for knowing (or not knowing) the world

Animistic or 'relational' ontologies encountered in non-Western (i.e. premodern) settings pose a challenge to Western (i.e. modern) knowledge production, as they violate fundamentalassumptions of Cartesian science. Naturalscientists who have tried seriously to incorporate subject-subject relations into their intellectual practice (e.g. Uexküll, Bateson) have inexorably been relegated to the margin

Endothelium-specific platelet-derived growth factor-B ablation mimics diabetic retinopathy.

Loss of pericytes from the capillary wall is a hallmark of diabetic retinopathy, however, the pathogenic significance of this phenomenon is unclear. In previous mouse gene knockout models leading to pericyte deficiency, prenatal lethality has so far precluded analysis of postnatal consequences in the retina. We now report that endothelium-restricted ablation of platelet-derived growth factor-B gen

Pain and sensory dysfunction 6 to 12 months after inguinal herniotomy

Inguinal hernia repair is associated with a 5%-30% incidence of chronic pain, but the pathogenesis remains unknown. We therefore evaluated pain and sensory dysfunction by quantitative sensory testing 6-12 mo after open herniorrhaphy. Before sensory testing, all patients (n = 72) completed a short-form McGill Pain Questionnaire and a functional impairment questionnaire. Sensory dysfunction in the i

MPCtools 1.0 -- Reference Manual

The manual describes MPCtools, a set a Matlab functions for simulation of MPC controllers. MPCtools supports linear state space models for prediction, linear inequality constraints on controls and states and quadratic cost functions. MPCtools also supports Simulink, enabling evaluation of MPC controllers applied to non-linear plants.

The electronic spectrum of VCr

The electronic spectrum of VCr has been studied using the complete-active-space self-consistent field complete-active-space second-order perturbation theory approach. Potential-energy curves for 12 electronic states have been computed. Transition energies, with respect to the X(2)Delta ground state, for some of the calculated electronic states are (with possible experimental values within parenthe

Allogeneic haematopoietic stem cell transplantation for metastatic renal carcinoma in Europe

Background: An allogeneic antitumour effect has been reported for various cancers. We evaluated the experience of allogeneic haematopoietic stem cell transplantation (HSCT) for renal cell carcinoma (RCC) in 124 patients from 21 European centres. Patients and methods: Reduced intensity conditioning and peripheral blood stem cells from an HLA-identical sibling (n = 106), a mismatched related (n = 5)

SweDCIS: Radiotherapy after sector resection for ductal carcinoma in situ of the breast. Results of a randomised trial in a population offered mammography screening

We studied the effect of postoperative radiotherapy (RT) after breast sector resection for ductal carcinoma in situ (DCIS). The study protocol stipulated radical surgery but microscopically clear margins were not mandatory. We randomised 1046 operated women to postoperative RT or control between 1987 and 1999. The primary endpoint was ipsilateral local recurrence. Secondary endpoints were contrala

Ring chromosomes and low-grade gene amplification in an atypical lipomatous tumor with minimal nuclear atypia

Atypical lipomatous tumors (ALTs) are characterized by supernumerary ring chromosomes and/or giant marker chromosomes, which typically are composed of interspersed, amplified 12q-sequences, are C-band negative, lack a-satellite sequences, and display high copy numbers of several oncogenes, including HMGA2 (a.k.a. HMGIC) and MDM2, from the 12q13-15 region. In the present study, we report the cytoge
