Spontaneous electrical and contractile activity correlated to 86Rb+ efflux in smooth muscle of guinea-pig mesotubarium

1. The spontaneous mechanical activity of guinea-pig mesotubarium consists of fused tetanic contractions lasting about 6 min, with a frequency of about four per hour. The muscle is completely relaxed between the contractions. Stretching the relaxed muscle elicits a contraction of the same appearance as the spontaneous ones. Comparison of preparations from oestrus (day 1 of the hormonal cycle), dio

Ab initio DFT study of Z-E isomerization pathways of N-benzylideneaniline

The ground state properties and absorption spectra of N-benzylideneaniline (NBA) have been studied at the density functional (DFT) and at the time-dependent density functional (TD-DFT) level of the theory. The equilibrium geometries of the E and Z isomers in the ground state and their vibrational frequencies have been computed. Furthermore, the excitation energies of the lowest excited singlet and

Present status and recent results from the APS SASE FEL

The Low-Energy Undulator Test Line (LEUTL) at the Advanced Photon Source, Argonne National Laboratory, is intended to demonstrate the basic operation of a SASE-based free-electron laser. Goals include comparison of experimental results With theoretical predictions and scaling laws, identification of problems relevant to fourth-generation light source construction and operation and the means of add

Novel immunodeficiency data servers

The Internet contains scientific information in increasing amounts. It is possible to obtain the latest information, and Web services can easily be maintained and updated. We have set up three Internet ser vices an immunodeficiencies. Immunodeficiency-related mutation information is available in immunodeficiency mutation databases (IDbases). Currently 14 registries are distributed, including infor

Effects of fused tryptophan rich peptides to a recombinant protein A domain on the partitioning in polyethylene glycol-dextran and Ucon-dextran aqueous two-phase systems

Genetic engineering has been used to construct fusion proteins with tryptophan containing peptides. The peptides and the fusion proteins have been partitioned in aqueous two-phase systems of poly(ethylene glycol) (PEG)-dextran and Ucon-dextran. The studied model protein was ZZT0, where Z is an engineered domain of domain B of staphylococcal protein A. The specially designed hydrophobic peptides, A

The Faint Optical Stellar Luminosity Function in the Ursa Minor Dwarf Spheroidal Galaxy

Analyses of their internal stellar kinematics imply that the dwarf spheroidal (dSph) companion galaxies to the Milky Way are among the most dark matter-dominated systems known. Should there be significant dark matter in the form of faint stars in these systems, the stellar luminosity function must be very different from that of a similar metallicity globular cluster, for which there is no evidence

Characterizing unsaturated solute transport by simultaneous use of dye and bromide

Variability in solute transport properties in the unsaturated zone is of growing concern due to environmental hazards. By combining dye and salt tracers, a detailed description of the solute transport can be made in both time and space. In this paper, qualitative and quantitative effects of preferential flow were investigated in a sandy loam. The experimental site was equipped with 64 TDR probes.

Endogenous free fatty acids repel and attract Collembola

We used video recording of the movement pattern of Protaphorura armata (Collembola) to test whether its avoidance of the odor of dead conspecifics extends to related species. P. armata was repelled by the odor of dead individuals of Onychiurus scotarius and Onychiurus circulans, but not by live individuals. Free palmitic, oleic, and linoleic acids were present in extracts of the three repellent sp

Adipic and Malonic Acid Aqueous Solutions: Surface Tensions and Saturation Vapor Pressures

The surface tension of adipic aqueous solution has been measured as a function of temperature (T = 278-313 K) and adipic acid mole fraction (X = 0.000-0.003) using the Wilhelmy plate method. A parameterization fitted to these data is presented. The evaporation rates of binary water-malonic and water-adipic acid droplets have been measured with a TDMA-technique at different temperatures (T = 293-30

Arkiv, fakultet, kyrka : festskrift till Ingmar Brohed

Ingmar Brohed var 1978-97 professor i kyrkohistoria vid Lunds universitet, därefter forskningschef vid Svenska kyrkans forskningsråd. Festskriften innehåller 26 artiklar som i huvudsak behandlar svensk och internationell kyrkohistoria från 1700-tal till sent 1900-tal, med perspektiv även från etnologi, historia, kyrkovetenskap, missionsvetenskap, religionssociologi och rättshistoria. De speglar på

High proteinase 3-anti-neutrophil cytoplasmic antibody (ANCA) level measured by the capture enzyme-linked immunosorbent assay method is associated with decreased patient survival in ANCA-associated vasculitis with renal involvement

Wegener granulomatosis (WG) and microscopic polyangiitis (MP), diseases associated with antineutrophil cytoplasmic antibodies (ANCA), had an extremely poor prognosis before the introduction of cyclophosphamide and corticosteroids for their treatment. However, there is still reduced patient survival, and some studies have documented severe side effects of the immunosuppressants used. This 10-yr fol

Glömda gudstecken : från fornkyrklig dopliturgi till allmogens bomärken

Popular Abstract in Swedish Bomärken har använts som ägarbeteckning och signatur i Norden in på 1800-talet, och i vissa reliktområden intill nutid. Bomärkena återfinns t.ex. i mantalslängder, jordaböcker och bouppteckningar, men även inskurna på äldre redskap, husgeråd och annat lösöre. Bomärkena har av somliga forskare ansetts ha utformats slumpvis, enbart med syftet att kunna skilja en bomärkesThe pioneering academic research on Merchant Marks (also known as identity marks, personal marks, ownership marks, identification marks, Hausmarken, Hofmarken, Marques de Propriété, bomärken) was done by professor Homeyer (1870). Since 1870 there has been an ongoing debate among scholars whether Merchant Marks are simply formed by chance and coincidence, as stated by Rehnberg (1938, 1951), Scheffe

Conduction Disturbances in Patients with Atrial Fibrillation

Background: The electrophysiological mechanisms underlying atrial fibrillation (AF) are incompletely understood. Experimental studies have shown that remodelling of the atrial myocardium is linked to the occurrence and perpetuation of AF. Interatrial conduction disturbances and also delayed conduction at the posteroparaseptal region have also been reported as potential arrhythmogenic substrates. H

The relative importance of fish predation and excretion effects on planktonic communities

The effects of planktivorous fish on lower trophic levels through predation on zooplankton and nutrient excretion were experimentally separated and their relative importance quantified in a eutrophic humic lake. The experiment was performed in 12 enclosures (3 mi), which initially were identical with respect to all components except fish. At the start of the experiment, caged fish not able to feed

A comparative study of capacitive immunosensors based on self-assembled monolayers formed from thiourea, thioctic acid, and 3-mercaptopropionic acid

A procedure was developed for the covalent coupling of anti-alpha-fetoprotein antibody (anti-AFP) to a gold surface modified with a self-assembled monolayer (SAM) of thiourea (TU). The performance of the SAM-antibody layer was compared to those of similar layers based on thioctic acid (TA) and 3-mercaptopropionic acid (MPA) by using flow injection capacitive immunosensor system. Covalent coupling

Dimensions of Health among Patients in Mental Health Services

Popular Abstract in Swedish Empiriska studier som fokuserar på subjektivt upplevd hälsa hos patienter i psykiatrin är sällsynta och merparten av de frågeformulär som finns är baserade på en medicinsk grund där objektivt observerbara sjukdomsindikatorer betonas. I studie I och II analyseras och beskrivs uppfattningar av begreppet hälsa hos patienter och sjuksköterskor i psykiatrisk vård med hjälp aEmpirical studies focusing on the subjective experience of health among patients in contact with the mental health services are rare and most questionnaires are based on a medical model that emphasizes objectively observed disease-oriented health indicators. In studies I and II perceptions of the concept of health among patients and nurses in mental health services were explored and described usin
