Phylogenetic relationships within the genus Cladonia, including Cladina (Cladoniaceae, Lecanoromycetes), were reconstructed based upon simultaneous analyses of DNA sequences and morphological and chemical data. We used sequences from the internal transcribed spacer 1 (ITS1), the 5.8 rDNA gene, and the internal transcribed spacer 2 (ITS2) of the nuclear rDNA gene cluster, and partial sequences from
Cells in mitosis were harvested from exponentially growing Chinese hamster ovary cells by the mitotic detachment technique. Immediately after harvesting, the mitotic cells were seeded in tissue culture flasks and incubated at 37 degrees C in a CO2 incubator. Care was taken not to perturb the progression of cells through the cell cycle. At every hour after seeding for 14 h, cells were collected for
Germline mutations in the CDKN2A tumor suppressor gene located on 9p21 have been linked to development of melanomas in some families. A germline 3-bp insertion in exon 2 of CDKN2A, leading to an extra arginine at codon 113 (113insR), has been identified in 17 Swedish melanoma families. Analysis of 10 microsatellite markers, spanning approximately 1 Mbp in the 9p21 region, showed that all families
Background In the US cotton industry, airborne cotton dust levels are regulated, and other countries are moving to specify safety limits for airborne endotoxins. There is concern about potential respiratory health hazards associated with agricultural and otherorganic dusts. In laboratories, ranking which samples have high and low levels of endotoxin is usually in good agreement between laboratorie
Intrauterine fetal growth was followed in a prospective study of 654 consecutive singleton pregnancies. Ultrasound fetometry was performed in gestational weeks 17, 32, and 39, and then weekly until delivery took place. A total of 408 fetuses were examined in the 39th week and 55 investigations were performed in the postterm period. This enabled us to follow the intrauterine growth of the normal fe
The paper investigates the possibility of using environmental management systems (EMSs) as a tool for the environmental management of supply chains. Based on interviews with environmental managers of selected companies, the paper highlights the importance of taking a long-term perspective in terms of both the cooperation with suppliers and developing the supply chain perspective for EMSs. The role
The increasing demand for high fluxes of X-rays to perform crystallography and material physics at MAX-lab is met with the MAX wiggler. The MAX-wiggler is a cold bore superconducting wiggler with 47 3.5 T poles and a period length of 61 mm and it has been constructed in-house at MAX-lab. The MAX-wiggler has now been installed and commissioned on the 1.5 GeV MAX-II storage ring at MAX-lab. This pap
The percentages of Type I muscle fibres were measured systematically in ATPase-stained, transverse cryostat sections of whole tibialis cranialis muscles from 8 young, adult beagles. The distance of the section from the origin of the muscle does not significantly affect the mean percentage. There are no identifiable differences in mean percentages between right and left muscles. Differences in mean
To discover whether islet sympathetic nerves are damaged during the autoimmune destruction of islet B-cells, we immunostained sections of pancreas from BioBreeder (BB) diabetic rats, using antibodies against vesicular monoamine transporter 2 (VMAT2), a marker of sympathetic nerve terminals. We found a marked decrease in the VMAT2-positive fiber area in the islets of BB rats that had been diabetic
The prevalence of diabetic retinopathy and the associated medical risk factors, such as age at onset and duration of diabetes, metabolic control, blood pressure, albumin clearance and serum creatinine, were studied in 501 patients with type I diabetes mellitus. The prevalence of retinopathy, characterized as simplex, maculopathy, preproliferative, and proliferative, was 60.5%. Patients with retino
Enzyme replacement is a potential therapy for mucopolysaccharidosis I (MPS I), a lysosomal storage disorder caused by alpha-L-iduronidase deficiency. Previous work showed improvement in the tissues of MPS I dogs treated intravenously for 3 months with recombinant human alpha-L-iduronidase (25,000 units or approximately 0.1 mg/kg/week). We have now treated an MPS I-affected dog for 13 months to ass
We tested the relative and combined effects of prey density and patch size on the functional response (number of attacks per unit time and duration of attacks) of a predatory reef fish (Cheilodactylus nigripes (Richardson)) to their invertebrate prey. Fish attacked prey at a greater rate and for longer time in large than small patches of prey, but large patches had naturally greater densities of p
Infrared dryers, both gas fired and electrically healed, have become a widespread technology in the paper industry. This work proposes a model for the absorption of thermal radiation in the thickness direction of a paper sheet. The model is based on the multilayer idealization of a paper sheet proposed by Scallan and Porch. In this model, the optical properties of paper are considered as the resul
Popular Abstract in Swedish Flertal studier talar för att såväl vaskulär demens som demens av Alzheimers typ är relaterade till blodtrycksnivå tidigare under livet. En studie har visat att redan blodtrycket vid 50- årsåldern är relaterat till kognitiva (intellektuella) funktioner vid 70-års ålder. En annan studie har visat att hypertoni i 70-årsåldern föregår utveckling av demens i ålder 80-85 år."Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. Examination included a medical and a psychological investigation, ultrasonographic measurement of carotid arteries, 24-hour ambulatory blood pressure monitoring, regional cerebral blood flo
Fifty-six type I diabetic patients with microalbuminuria (albumin excretion rate 20-200 micrograms/min) were characterized as to sex, age, duration of diabetes, smoking habits, blood pressure, glomerular filtration rate, urinary NC1 (the carboxy-terminal domain of collagen IV), and Tamm-Horsfall protein excretion rate. Albumin excretion rate was considered a sign of glomerular damage, NC1 excretio
Salla disease is a lysosomal storage disorder of unknown etiology, characterized biochemically by increased urinary excretion of N-acetylneuraminic acid. This compound has now been shown to occur in abnormally large amounts in liver and cultured skin fibroblasts from these patients. Quantification of N-acetylneuraminic acid was performed using a new gas-chromatography/mass spectrometric single-ion
During a 13 year period, 286 patients with cervical disc herniation and/or spondylotic spurs, were subjected to anterior decompression and vertebral interbody fusion with autologous bone. Twenty patients were re-admitted in the late postoperative period due to recurrent radicular symptoms and/or signs of myelopathy. In these patients myelography was performed again. In 14 patients spinal cord comp
A section of the Vitabdck Clays at Eriksdal in southern Sweden was sampled for vertebrate fossils. Large bulk samples were collected from three horizons, including two coquina beds, VC3 and VC11, and a silty clay bed, VC7. Shark teeth are very common and constitute the main portion of the vertebrate material discussed herein. The selachian tooth faunas are almost exclusively represented by hybodon
Higher bone mineral density (BMD) has been reported in weight-loaded skeletal regions and lower BMD in unloaded regions in active athletes compared with controls. These discrepancies remain the first decades after cessation of active careers in former athletes with no remaining discrepancies found after age 65 years compared with age- and gender-matched controls. Physical activity is reduced after
