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
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
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
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
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.
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
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
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
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
Mucosal surfaces of the reproductive tract as well as their secretions have important roles in preventing sexual transmission of HIV-1. In the current study, the majority of the intrinsic anti-HIV-1 activity of human seminal plasma (SP) was determined to reside in the cationic polypeptide fraction. Antiviral assays utilizing luciferase reporter cells and lymphocytic cells revealed the ability of w
The aim of the article is to discuss the interpretation of the Romanesque round church towers in Scandinavia. The article focuses on the 15-19 churches with round towers in medieval Denmark, Sweden and Norway, with the main part in Southern Schleswig and Scania; none are known from Finland. The chronology and social context, function and meaning of the church towers are discussed. Finally a list o
Abstract Objective. Infravesical obstruction leads to growth of urinary bladder smooth-muscle cells. The ganglion cells innervating the bladder muscle also increase in size. Stretch of detrusor muscle cells rapidly activates c-Jun NH(2)-terminal kinase (JNK), which phosphorylates the transcription factor c-Jun, and stimulates the synthesis of the cotranscription factor ATF3. The aim of the study w
Conditionally replicative adenovirus (CRAD) represents a promising approach for cancer therapy. Several CRADs controlled by the human telomerase reverse transcriptase promoter have been developed. However, because of their replicative capacity, the importance of cancer specificity for CRADs needs to be further emphasized. In this study, we have developed a novel dual-regulated CRAD, CNHK500-mE, wh
