Due to its unique ability to split water, Photosystem II (PSII) is easily accessible to oxidative damage. Photoinhibited PSII centres diffuse laterally from the grana core region of the thylakoid membrane to the stroma lamellae in order to allow replacement of damaged proteins and cofactors. The 'new born' PSII centres in this region are characterized by the absence of the water splitting capacity
PURPOSE. To compare intersubject variability and normal limits of threshold values between the new Swedish interactive test algorithm short wavelength automated perimetry (SITA SWAP) and the older Full Threshold SWAP programs (Carl Zeiss Meditec, Dublin, CA). METHODS. Normal reduction of differential tight sensitivity with age, age-corrected thresholds, intersubject variability, and normal limits
Objective. When treatments with the potential to change the natural history of a disease are introduced, their longer-term effect on costs and quality of life (utility) has to be estimated using economic models. However, to remain useful tools, models must be updated when new information becomes available. Our earlier models in rheumatoid arthritis (RA) have been based on functional status, but it
Background: Pancreatic acinar-like metaplasia has previously been described in the gastric mucosa and in the distal part of the oesophagus. The resemblance to pancreatic acinar cells prompted us to study the possible occurrence of secretory pancreatic proteins in these cells. Methods: Seven specimens obtained from the distal oesophagus at gastroscopy where routine microscopy showed pancreatic acin
In a previous study (Chemical Physics Letters 2005, 401, 385) we computed the optical rotatory dispersion of (S)-propylene oxide in gas phase and solution using the hierarchy of coupled cluster models CCS, CC2, CCSD, and CC3. Even for the highly correlated CC3 model combined with a flexible basis set, the theoretical gas-phase specific rotation at 355 nm was found to be negative in contrast to the
The complete mitochondrial genome of the endangered Banded Hare wallaby (Lagostrophus fasciatus) was sequenced and used for phylogenetic analysis. The data set consisted of 10 377 nucleotides (3459 amino acids) from three kangaroo species. The phylogenetic analyses strongly supported the hypothesis that the Banded Hare wallaby is the sister-group of the wallaroo (subfamily Macropodidae). In additi
Chiral bifunctional oxabicyclodecanediones (keto lactones) were synthesized from the corresponding bicyclo[3.3.1]nonane diones 1-5 by employing a regioselective Baeyer-Villiger oxidation. Enantiomers with high enantiomeric excess were obtained by chiral HPLC enantiomer separation on microcrystalline, triacetylcellulose column. Circular dichroism spectra of molecules containing two chromophores, na
The optimal temperature during targeted temperature management (TTM) for comatose patients resuscitated from out-of-hospital cardiac arrest is unknown. It has been hypothesized that patients with long no-flow times, for example those without bystander CPR would have the most to gain from temperature management at lower temperatures.
PURPOSE Cardiovascular disease (CVD) is a potential adverse effect of endocrine treatment (ET) for prostate cancer (PC). We investigated absolute and relative CVD risk in 76,600 patients with PC undergoing ET, curative treatment, or surveillance. METHODS PCBaSe Sweden is based on the National Prostate Cancer Register, which covers more than 96% of PC cases. Standardized incidence ratios (SIRs) and
Negative pressure wound therapy (NPWT) results in 2 types of tissue deformation, macrodeformation (ie, wound contraction) and microdeformation (ie, the interaction of tissue and dressing on a microscopic level). These effects have been delineated for one type of wound filler, foam, but not for gauze. The mechanical deformation initiates a signaling cascade which ultimately leads to wound healing.
Clinical studies have suggested a link between the sensory trigeminal system and the parasympathetic ganglia. Calcitonin gene-related peptide (CGRP) is a sensory neuropeptide which plays an important role in vasodilatation and pain transmission in craniocervical structures. The present study was designed to examine if CGRP and CGRP receptor components are present in the human sphenopalatine gangli
Only in a handful of cases in world history has female rule been seen by contemporary observers as desirable and been sustained for long periods of time. Drawing on European, Malay and Chinese sources, this article investigates the reasons for the institutionalisation of female rule in the Malay sultanate of Patani (presently in southern Thailand) for most of the period between c. 1584 and 1711. I
Popular Abstract in Swedish I den boreala och tempererade klimatzonen är växternas fenologi synkroniserad med årstidsväxlingar i temperatur och dagslängd. För lövträd påverkar tidpunkten för knoppsprickning och lövfärgning både tillväxt och risktagande. En förlängd växtsäsong till följd av ett varmare klimat innebär sannolikt högre produktivitet inom skogsbruket, men kan också leda till ökad risk Plant phenology in the boreal and temperate climate zones is synchronised with seasonal changes in temperature and photoperiod. For deciduous trees, timing of budburst and leaf colouring define the growing season length and express adaptations to trade-offs in growth and risks. An extended growing season due to climate warming will likely increase forest productivity, however these potential benef
The pharmacodynamics (PD), pharmacokinetics (PK) and metabolism of the sulphonylurea(SU) and its metabolites (M1 and M2) , and of another SU, glipizide (Gz) were studied in diabetes patients and healthy volunteers. In one study Caucasians and Chinese were compared. Sensitive and selective methods for determination of drug levels and concentrations of insulin and proinsulin were used. The terminal
