Visibility of microcalcification clusters and masses in breast tomosynthesis image volumes and digital mammography: A 4AFC human observer study.
Purpose: To investigate the visibility of simulated lesions in digital breast tomosynthesis (BT) image volumes compared with 2D digital mammography (DM). Methods: Simulated lesions (masses and microcalcifications) were added to images of the same women acquired on a DM system (Mammomat Novation, Siemens) and a BT prototype. The same beam quality was used for the DM and BT acquisitions. The tota

Quasi-resonant Energy-transfer In Collisions - Na2(a(1)sigma(u)(+))+k(4s)
Cross sections for electron energy transfer from the initial rotational state J' of the two lowest vibrational levels upsilon' = 0 and upsilon' = 1 of excited dimers Na2(A) to potassium atoms as described by Na2(A1Sigma(u)+, upsilon'J') + K(4S) --> Na2 (X1Sigma(g)+, upsilon''J'')+K(4P)+DeltaE have been examined by laser-induced fluorescence. A strong increase of the cross section by as much as an

The rate of crossings of a quadratic form of an n-dimensional stationary Gaussian process
Consider a quadratic form of a vector valued differentiable stationary Gaussian process. The crossing intensity of a fixed level depends on the joint correlation structure of the process and its derivative, but no simple exact form is known for the general case. We give the first and second terms in an asymptotic expansion, which is valid as the level tends to infinity, and show how to find higher

Rifabutin accumulates in the lens and reduces retinal function in the rabbit eye
PURPOSE: To study the toxicology of rifabutin in the rabbit eye with emphasis on retinal function and histopathology.METHODS: Seven rabbits received a daily dose of rifabutin during 15 months. Six rabbits receiving only the vehicle were used as controls. Repeated standardized full-field electroretinograms (ERG) were assessed. After discontinuing treatment, the rabbits were killed and the cornea, t
Prediction of disease-related mutations affecting protein localization.
Eukaryotic cells contain numerous compartments, which have different protein constituents. Proteins are typically directed to compartments by short peptide sequences that act as targeting signals. Translocation to the proper compartment allows a protein to form the necessary interactions with its partners and take part in biological networks such as signalling and metabolic pathways. If a protein
Eivor Burbeck i fantasins museum
Essay over the life and letters of Swedish artist and filmmaker Eivor Burbeck (1926 - 1965), a modernist forerunner within poetry as well as experimental film, and one of the few active female members of the Stockholm Independent Film Group during the 1950s. The article includes a complete bibliography over her own works.

Increased Cartilage Oligomeric Matrix Protein Concentrations in Equine Digital Flexor Tendon Sheath Synovial Fluid Predicts Intrathecal Tendon Damage.
Objectives: To evaluate digital flexor tendon sheath (DFTS) synovial fluid cartilage oligomeric matrix protein (COMP) concentrations as a molecular marker for intrathecal pathology. Study Design: Case control study. Animals: Horses (n=46) with DFTS tenosynovitis; 23 fresh cadaver horses. Methods: DFTS synovial fluid samples were collected from clinical cases with noninfected DFTS tenosynovitis and
Contextualizing Regional Innovation Systems in a Globalizing Learning Economy: On Knowledge Bases and Institutional Frameworks
In order to advance the understanding of which types of regional innovation system represent effective innovation support for what kinds of industry in different regions analyses must be contextualised by reference to the actual knowledge base of various industries as well as to the regional and national institutional framework, which strongly shape the innovation processes of firms. Of special im

Increased Risks of Coronary Heart Disease and Stroke Among Spousal Caregivers of Cancer Patients.
BACKGROUND: Spousal caregivers of cancer patients suffer psychological and physical burdens, which may affect their risk of subsequently developing coronary heart disease (CHD) and stroke. METHODS AND RESULTS: Cancer patients were identified in the Swedish Cancer Registry, and information on their spouses was retrieved from the Swedish Multi-Generation Register. Follow-up of caregivers was carri
Cigarette smoke extract promotes human vascular smooth muscle cell proliferation and survival through ERK1/2- and NF-κB-dependent pathways.
Tobacco use is one of the major risk factors of cardiovascular disease. The underlying molecular mechanisms that link cigarette smoke to cardiovascular disease remain unclear. The present study was designed to examine the effects of dimethyl sulfoxide (DMSO)-soluble smoke particles (DSPs) on human aortic smooth muscle cell (HASMC) cultures, and to explore the mitogen-activated protein kinase (MAPK
