The aim of this study was to explore the previous personalities of patients, their behavior during the course of the disease, and the relationship between the previous personality and vocally disruptive behavior of severely demented patients. Twenty-one severely demented patients identified as vocally disruptive and 19 severely demented control subjects who were matched for gender and ward were st

Biological molecular motors that are constrained so that function is effectively limited to predefined nanosized tracks may be used as molecular shuttles in nanotechnological applications. For these applications and in high-throughput functional assays (e. g., drug screening), it is important that the motors propel their cytoskeletal filaments unidirectionally along the tracks with a minimal numbe

Recent Hubble Space Telescope observations of a large sample of globular clusters reveal that every cluster contains between 40 and 400 blue stragglers.The population does not correlate with either stellar collision rate (as would be expected if all blue stragglers were formed via collisions) or total mass (as would be expected if all blue stragglers were formed via the unhindered evolution of a s

BACKGROUND: The aim of the study was to evaluate how well vascular function is retained in a cadaver kept in a room with a temperature of 21 degrees C. METHODS: The aorta and pulmonary artery of rats were investigated in organ baths as fresh controls and after 1, 2, 3, or 6 hours' storage in the cadaver. Six-hour-old cadaver aortas were transplanted and investigated after 24 hours and 60 days. RES

Purpose: To evaluate the short-term feasibility, efficacy, and safety of a modular bifurcated stent-graft with an internal iliac artery (IIA) side branch for endovascular repair of aortoiliac aneurysms. Methods: Between 2002 and 2005, 10 male patients (median age 75 years, range 59–83) were treated with a bifurcated stent-graft that included a unilateral side branch for the IIA. The median diamet

Man har gett namnet ”vitalister” till de tänkare som tillskriver den levande materian en särskild status. Den särskilda statusen kräver vissa uppoffringar. Vitalismen är tvungen att erkänna ett orsaksbegrepp som avviker markant från det dominerande mekanistiska modellen i det modernistiska programmet. Den vitala ”kraften” eller ”principen”, agerar genom den organiska vävnaden för att orsaka den rö

ETS gene fusions have been characterized in a majority of prostate cancers; however, the key molecular alterations in ETS-negative cancers are unclear. Here we used an outlier meta-analysis (meta-COPA) to identify SPINK1 outlier expression exclusively in a subset of ETS rearrangement-negative cancers (similar to 10% of total cases). We validated the mutual exclusivity of SPINK1 expression and ETS

An excited well-deformed rotational band has been observed in the N = Z odd-odd nucleus Cu-58. The first excited state in this band decays via gamma emission to the spherical states associated with the first minimum in the potential, thus providing for its unambiguous assignment to Cu-58. I, contrast, its bandhead decays via emission of a prompt 2.4(1) MeV proton to an excited state in the daughte

Purpose: Tardigrades have a reputation of being extremely tolerant to extreme environmental conditions including tolerance to ionizing radiation while in a desiccated, anhydrobiotic state. However, the evidence for radio-tolerance in tardigrades is based on only one previous report, and there is an obvious need for complementary studies. In this paper we report an investigation on radio-tolerance

By the incorporation of size-selected Au nano-particles in Ti Schottky contacts on silicon carbide, we could observe considerably lower the barrier height of the contacts. This result could be obtained for both n- and p-type Schottky contacts using current-voltage and capacitance voltage measurements. For n-type Schottky contacts, we observed reductions of 0.19-0.25 eV on 4H-SiC and 0.15-0.17 eV o

The purpose of this study was to establish, and characterize a porcine model of acute, controlled retinal ischemia. The controlled retinal ischemia was produced by clamping the ocular perfusion pressure (OPP) in the left eye to 5 mm Hg for 2 h. The OPP was defined as mean arterial blood pressure (MAP) minus the intraocular pressure (IOP). It was clamped to 0-30 mm Hg by continuous monitoring of MA

Relapsing polychondritis ( RP) is an autoimmune disease that affects extra-articular cartilage. Matrilin-1-induced relapsing polychondritis (MIRP) is a model for RP and is useful for studies of the pathogenic mechanisms in this disease. There are indications that the major histocompatibility complex (MHC) class II plays a major role in RP, since DR4(+) patients are more commonly affected than cont

In the airways of asthmatic patients, activated fibroblasts account for an excessive matrix production including proteoglycans (PGs). Transforming growth factor-beta. (TGF beta), metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) play key rotes in matrix turnover. It is unclear whether asthma therapy with combination of inhaled glucocorticoids and long-acting beta(2)-agonists affects me

This study reports the findings of how district nurses (n = 23) and hospital nurses (n = 9) in cancer care experienced social support in immediate connection with demanding care situations, as well as the effect of systematic clinical supervision. The study is based on their own accounts. The data were collected by means of semi-structured interviews. The findings indicate that there is a great ne
