We report and compare highly resolved, simultaneously recorded absorption and CD spectra of active Photosystem II (PSII) samples in the range 440-750 nm. From an appropriately scaled comparison of spinach membrane fragment (BBY) and PSII core spectra, we show that key features of the core spectrum are quantitatively represented in the BBY data. PSII from the cyanobacterium Synechocystis 6803 displ
Plasma autoantibodies (aAbs) against the oxidized DNA base derivative 5-hydroxymethyl-2'-deoxyuridine (5-HMdU) are potential biomarkers of cancer risk and oxidative stress. We examined their association with a number of cancer risk factors: smoking, alcohol habits, body fatness, and absence of the glutathione S-transferases M1 and T1 (GSTM1 and GSTT1) in a sample from the population-based Malmö Di
Conclusions. Preoperative gentamicin in combination with vestibular 'prehab' offers a possibility to reduce postoperative malaise and speed up recovery and may be used for patients undergoing such surgery when there is remaining vestibular function. Objectives. Removal of pontine angle tumours in a patient with remaining vestibular function causes symptoms of acute vestibular loss. A simultaneous
The present work is a contribution to the study of Christian Arabic literature. An apologetic treatise on the unity and trinity of God incorrectly attributed to Yahya ibn Adi (d. 974) is edited for the very first time and provided with a comprehensive word index. The edition is based on six manuscripts found in Egypt. Four of these manuscripts have so far not been known to scholarly research. The
The release gamma-aminobutyric acid (GABA) and ATP from rat beta cells was monitored using an electrophysiological assay based on overexpression GABAA or P2X2 receptor ion channels. Exocytosis of LDCVs, detected by carbon fiber amperometry of serotonin, correlated strongly (similar to 80%) with ATP release. The increase in membrane capacitance per ATP release event was 3.4 fF, close to the expecte
OBJECTIVE: To characterize the clinical phenotype, with emphasis on electrophysiology and blood flow measurements, of a family with dominant optic nerve atrophy and an identified mutation in the OPA1 gene. METHODS: Seven family members were examined. Ophthalmological evaluation included testing of visual acuity, ophthalmolscopy, kinetic perimetry, color vision testing, full-field electroretinograp
Background: We chose a set of candidate single nucleotide polymorphisms (SNPs) to investigate gene-environment interactions in three types of cancer that have been related to air pollution (lung, bladder and myeloid leukemia). Patients and methods: The study has been conducted as a nested case-control study within the European Prospective Investigation into Cancer and Nutrition cohort (409 cancer
We investigated whether dorsal hindbrain and/or peripheral cocaine- and amphetamine-regulated transcript peptide (CARTp) acts to suppress gastric emptying of a caloric stimulus. Furthermore, effects of dorsal hindbrain CARTp on sucrose consumption and licking microstructure was studied, as well as the possible contribution of corticotropin-releasing factor (CRF) receptors to mediate effects of CAR
Popular Abstract in Swedish Användningen av informations och kommunikationsteknik (IKT eller IT) påverkar vårt sätt att kommunicera i arbetslivet. Det underlättar distansarbete och skapar möjligheter till s.k. virtuella möten - att samarbeta utan att träffas fysiskt. Detta kan i sin tur påverka behovet av pendlings- och tjänsteresor, genom att vi får tillgång information, en funktion eller en tjänInformation and Communication Technologies change the way we work and communicate, enabling us to telework and to have virtual meetings - collaborating without a physical meeting. This can influence the need for commuting and business travel by provision of access to an activity without mobility - virtual mobility. The large environmental impact of travel makes this potential travel reduction inte
The 80+ Studies are collecting longitudinal data regarding medical, psychological, and sociological aspects of 80-year-old people in Lund, Sweden and Reykjavik, Iceland. Methods and Samples: The research design and instruments were identical at the two cites. The number of participants was 139 and 151 respectively. Results: The Icelandic sample had a lower level of educational attainment, a higher
Rabbit pellets collected from the field were colonized by Podospora pleiospora at the exclusion of other coprophilous fungi, suggesting antibiosis. in liquid culture, P. pleiospora produced sordarin (1); sordarin B (2), a new compound in which sordarose is replaced by rhamnose, hydroxysordarin (3); and sordaricin (4). The major compounds I and 2 exhibited minimum inhibitory concentrations of 0.5-2
In this paper, we analyse in detail two famous space weather events; a railway problem on 13-14 July 1982 and a power blackout on 30 October 2003. Both occurred in Sweden during very intensive space weather storms and each of them a few years after the sunspot maximum. This paper provides a description of the conditions on the Sun and in the solar wind leading to the two GIC events on the ground.
Near- and mid-infrared absorption spectra of pure water and aqueous 1.0 g/dL glucose solutions in the wavenumber range 8000-950 cm(-1) were measured in the temperature range 30-42 C in steps of 2 degreesC. Measurements were carried out with an FT-IR spectrometer and a variable pathlength transmission cell controlled within 0.02 degreesC. Pathlengths of 50 mum and 0.4 mm were used in the mid- and n
The Bog Ecosystem Research Initiative (BERI) projectwas initiated to investigate, at five climaticallydifferent sites across Europe, the effects of elevatedCO2 and N deposition on the net exchange ofCO2 and CH4 between bogs and the atmosphere,and to study the effects of elevated CO2 and Ndeposition on the plant biodiversity of bogcommunities. A major challenge to investigate theeffects of elevated
In peatlands the balance between litter input and decay loss in the oxic acrotelm determines the rate of carbon input to the anoxic catotelm with carbon lost at very slow rate. In the acrotelm the C/N-quotient decreases with depth and indicates the loss of carbon from the acrotelm. On one boreo-nemoral and three subalpine ombrotrophic bogs in Sweden the carbon losses in the acrotelm plus the appar
Inactivation of factor Va (FVa) by activated protein C (APC) is a key reaction in the down- regulation of thrombin formation. FVa inactivation by APC is correlated with a loss of FXa cofactor activity as a result of three proteolytic cleavages in the FVa heavy chain at Arg(306), Arg(506), and Arg(679). Recently, we have shown that heparin specifically inhibits the APC- mediated cleavage at Arg(506
Volatile anaesthetics may modulate cerebrovascular resistance, but their direct actions on human cerebral arteries are unknown. In the present study, we have evaluated the effects of halothane and isoflurane at different MAC (0.4, 1.0 and 2.0) on contractions induced by depolarization (potassium) or receptor stimulation (prostaglandin F2 alpha) in isolated ring segments of human pial arteries. Nei
Seedlings of Pinus sylvestris L. were grown in Plexiglas(R) observation chambers in limed (CaCO3, pH 5.0 and 5.9) and untreated (pH 4.1) peat. The seedlings were either colonized by the mycorrhizal fungus Paxillus involutus (Batsch: Fr.) Fr. Or were non-mycorrhizal. After 18 wk in the observation chambers, N-15-labelled organic nitrogen, as lyophilized and ground mycelium of Suillus variegatus (Sw
