Recent investigations of the DNA interactions with cationic surfactants and catanionic Mixtures are reviewed. Several techniques have been used such as fluorescence microscopy, dynamic light scattering, electron microscopy, and Monte Carlo simulations. The conformational behaviour of large DNA molecules in the presence of cationic surfactant was followed by fluorescence microscopy and also by dyna

I rapporten redovisas dagens kunskapsnivå avseende termiskt klimat, luftkvalitet, ljud samt elektromagnetiska fält. Dessutom redovisas de överkänslighetsrelaterade besvär, sjukdomsrelaterade besvär och symptom eller allmänna obehag av diskomfort som anses orsakas av inomhusmiljön. Rapporten är skriven så att de som arbetar med inomhusmiljörelaterade frågor, med varierande bakgrund, erbjuds en tvär

Among hole-nesting birds, the blood-sucking hen flea is a common parasite affecting both nestlings and parents. By adding fleas to marsh tit (Parus palustris) nests, I aimed to investigate the effect of fleas on nestling growth rate and parental effort as well as evaluating a potential mechanism by which fleas affect nestlings (i.e., resting metabolic rate; RMR). Nestlings from flea-infested brood

A multicenter, open-label, randomized efficacy and safety study was performed with combined human chorionic gonadotropin (hCG) and recombinant follicle-stimulating hormone (recFSH) (Puregon(R)) treatment to induce spermatogenesis in hypogonadotropic hypogonadal male patients. Patients were pretreated for 16 weeks with hCG to normalize testosterone levels. A total of 30 of 49 (61%) subjects had nor

Background: A new technique, cutaneous field stimulation (CFS), which activates electrically unmyelinated C-fibers, is used to treat localized itch. Its action is similar to that of capsaicin, the pungent agent in hot peppers, which enhances delayed allergic reactions. The aim of the study was to investigate how experimental contact dermatitis responds to CFS. Methods: Twelve patients with contac

This review is a comprehensive summary of available collection techniques in supercritical fluid extraction (SFE), with emphasis on which parameters are especially important for a successful analyte collection. Environmental, biological and agricultural applications, including several types of sample matrices and analyte groups, are discussed with respect to choice of collection mode and optimizat

Tuberculosis remains a major global cause of morbidity and mortality. There is an urgent need for improved bacteriologic diagnosis of Mycobacterium tuberculosis infection. Three methods for rapid identification of M. tuberculosis in sputum samples (direct microscopy, gas chromatography-mass spectrometry [GC-MS], and polymerase chain reaction [PCR]), were compared with culture on Lowenstein-Jensen

Studies of language in children with mild-to-moderate hearing impairment ( HI) indicate that they often have problems in phonological shortterm memory (PSTM) and that they have linguistic weaknesses both in vocabulary and morphosyntax similar to children with specific language impairment (SLI). However, children with HI may be more likely than children with SLI to acquire typical language skills a

The entity sinusitis, bronchiectasis, and situs inversus is since long named Kartagener syndrome. Nowadays the designation used is primary ciliary dyskinesia (PCD), which implies cilia with decreased or total absence of motility, which may result in sinusitis, chronic bronchitis, bronchiectasis, and male infertility. A large number of deficiencies detectable on the ultrastructural level give rise

Popular Abstract in Swedish Tillväxthormon (GH) insöndras stötvis från hypofysen. Insöndringen är som högst nattetid, och de högsta nivåerna ses under puberteten för att därefter avta succecivt med ökande ålder. En av de vanligaste orsakerna till brist på GH är godartade tumörer i hypofys och hypofysnära områden där även behandling med kirurgi och strålbehandling kan bidra till hypofysinsufficiensIn childhood onset growth hormone deficiency (GHD) a reduction in cardiac left ventricular mass (LVMi) and impairment of cardiac systolic function, as well as in glomerular filtration rate (GFR) has been shown. In study I, we showed that a low dose of GH treatment for 10 months resulted in increased LVMi and kidney size. No significant improvement in cardiac systolic function or GFR, except for a

Den 8-9 oktober 2003 anordnade Statens legemiddelverk i Norge i samarbete med Läkemedelsverket en workshop som syftade till att ta fram behandlingsrekommendationer för behandling av artros.

The aim of this paper is to propose a framework for the evaluation of policy instruments designed to affect development and dissemination of new energy technologies. The evaluation approach is based on the analysis of selected outcome indicators describing the process of technical change, i.e. the development and dissemination of new energy technologies, on the basis of a socio-technical systems a
