(1S, 4R, 6R)-6-Hydroxybicyclo[2.2.2]octan-2-one, (+)-1, is synthesized from its enantiomer in 6 steps using a combination of orthogonal protecting groups and red-ox chemistry.
We report on likely mixed paternity in a natural population of snow skinks (Niveoscincus mirolepidoms) from alpine Tasmania, Australia. This species is nonterritorial and males guard females after copulation, Suggesting that guarding behavior has evolved to prevent rival mating of still-receptive females. To what degree does this mate-guarding prevent rival copulations? We sampled gravid females a
Single-nucleotide polymorphisms (SNPs) in the major histocompatibility complex class II transactivator (MHC2TA) gene encoding the class II transactivator have been associated with multiple sclerosis, rheumatoid arthritis, and myocardial infarction in the Swedish population. We used a case-control approach to investigate the prevalence of a relevant variant in Swedish systemic lupus erythematosus (
Background: The role of water hardness as a risk factor for cardiovascular disease has been widely investigated and evaluated as regards regional differences in cardiovascular disease. This study was performed to evaluate the relation between calcium and magnesium in drinking water and diet and risk factors for cardiovascular disease in individuals living in hard and soft water areas with consider
A density functional theory based on a complete active space self consistent field (CASSCF) reference function with exact exchange is discussed. It is first shown that such a theory may be formulated with a correlation potential dependent on the density function and on the active space used. Auxiliary functions, such as the on-top two-particle density, are used to define uniquely the potential for
Raloxifene reduces vertebral fracture risk in postmenopausal women with osteoporosis and established osteoporosis, but its efficacy in women with osteopenia has not been studied. The objective of this study was to evaluate the effect of raloxifene hydrochloride on the risk of vertebral fractures in postmenopausal women with osteopenia and to compare this effect with that in women with osteoporosis
Popular Abstract in Swedish I denna avhandlingen studeras solljusets effekter på organiskt material och bakterier i akvatiska ekosystem. Särskild inriktas arbetet på UV-B strålning då instrålning till jorden av detta kortvågiga UV-ljus troligen ökar p g a ett minskat ozonlager. Ozonlagersproblematiken är verifierad över både norra och södra halvklotet. Resultaten visar på att en betydande del av This thesis examines the role of sunlight, specifically ultraviolet-B radiation (280-320 nm), on dissolved organic matter (DOM) and bacteria in lakes. Field experiments in lakes with different humic contents and geographical locations have been performed. Photooxidation result in that part of DOM is oxidized to inorganic carbon (DIC), mainly CO2. The photooxidation rate can be of the same magnitu
Purpose: To determine if mutations in the retinal transcription factor gene NRL are associated with retinopathies other than autosomal dominant retinitis pigmentosa (adRP). Methods: Genomic DNA was isolated from blood samples obtained from 50 patients with Leber Congenital Amaurosis (LCA), 17 patients with the Enhanced S-Cone Syndrome (ESCS), and a patient with an atypical retinal degeneration tha
Photon-echo-relaxation measurements made on the 3H4-3P0 transition of 0.01 at. % Pr3+:YAG (where YAG represents yttrium aluminum garnet), 3H4-1D2 transition in 0.1 at. % Pr3+:YAlO3, and 7F0-5D0 transition in 0.25 at. % Eu3+:YAlO3 show that the photon-echo relaxation rate increases when the intensities of the excitation pulses are increased. Although a part of the relaxation-rate increase in Pr3+:Y
Second- and third-generation cephalosporins, notably cefotetan, are increasingly implicated in severe, sometimes fatal immunemediated hemolytic anemia. We describe a 26-year-old woman who developed severe hemolytic anemia 2 weeks after receiving a single prophylactic dose of cefotetan during cesarean delivery. The patient's DAT was weakly reactive for IgG and her serum reacted with cefotetan-coate
Gastrointestinal stromal tumors (GISTs), the most common mesenchymal tumors of the digestive tract, are believed to arise from the interstitial cells of Cajal. GISTs are characterized by mutations in the proto-oncogene KIT that lead to constitutive activation of its tyrosine kinase activity. The tyrosine kinase inhibitor STI571, active against the BCR-ABL fusion protein in chronic myeloid leukemia
Popular Abstract in Swedish Påverkan av faktor V Leiden-mutationen på risk för utveckling av neovaskulära komplikationer efter centralvenstrombos studerades. Hos patienter med mutationen var risken nästan tre gånger högre att utveckla neovaskulära komplikationer än hos patienter utan mutationen. Synnervssvullnad , som nyligen har presenterats som en indikator på god prognos vid centralvenstrombosThe influence of the factor V Leiden mutation on the development of neovascular complications in central retinal vein occlusion was studied. The presence of the mutation was found to enhance the risk of developing neovascular complications almost threefold compared to in patients without the mutation. Optic nerve head swelling, which recently has been presented as an indicator of good prognosis i
To investigate how the relation between the control time and the total amount of water varies with the water application rate at manual fire fighting operations, six different experimental fire test series were studied. In spite of being quite different, the experiments prove to give similar results. Plotting the total volume of water required against the application rate, gives a diagram in the s
