We have constructed extensive 18S–28S rDNA dinoflagellate phylogenies (>200 sequences for each marker) using Maximum Likelihood and Bayesian Inference to study the evolutionary relationships among marine and freshwater species (43 new sequences). Our results indicated that (a) marine and freshwater species are usually not closely related, (b) several freshwater species cluster into monophyletic gr
Knowledge of the natural emissions of mercury in the Mediterranean basin, which has large cinnabar anomalies, has particular weight as these deposits could be an important source of atmospheric mercury. Data on the degassing rate of mercury from soils sampled both in mineralized areas (Mt. Amiata, Italy and Almaden, Spain) and rural areas are reported. Measurements were carried out 'in situ' using
Microglia are the inflammatory cells of the brain and are activated in neuropathological conditions. To study the biology of microglia, these cells can be isolated from the brain and analyzed in terms of pro- and anti-inflammatory cytokine production, involvement of intracellular signaling pathways upon inflammatory stimuli, phagocytosis, and several more biological aspects to understand their rol
Polyamine analogue treatment results in growth inhibition and sometimes in cell death. Therefore, polyamine analogues are considered in the treatment of cancer; however, the cellular properties that govern sensitivity are not known. The objective of this study was to elucidate molecular mechanisms behind apoptosis induced by the polyamine analogue N, N-diethylnorspermine (DENSPM). Four different b
Background: Levosimendan and volatile anesthetics have myocardial pre-conditioning effects. beta-1 adrenergic receptor antagonists may inhibit the protective effect of volatile anesthetics. No information exists as to whether this also applies to the pre-conditioning effect of levosimendan. We therefore investigated whether levosimendan added to metoprolol would demonstrate a cardioprotective effe
BACKGROUND AND OBJECTIVE: An estimated 150 million people worldwide use cannabis. The effect of cannabis on anaesthetic requirements in humans does not appear to have been studied. METHODS: In this prospective, randomized, single-blinded study, 30 male patients using cannabis more than once per week (group C) and 30 nonusers (group NC), aged 18-50 years, were induced with propofol 1.5, 2, 2.5, 3 o
There is currently a challenge to produce an electrocardiogram (ECG) recording of waveforms that are "standard" and also achieve the "noise immunity" required for continuous monitoring. The potential solutions that have been considered are to label each torso-recorded ECG as "nonstandard, torso-recorded," designate torso placement as "standard," or to reconstruct the "equivalent distally recorded
Complement activation and resulting opsonisation with C3b form key arms of the innate immune defense against infections. However, a wide variety of pathogens subvert complement attack by binding host complement inhibitors, which results in diminished opsonophagocytosis and killing of bacteria by lysis. Human C4b-binding protein (C4BP) binds Neisseria gonorrhoeae and Streptococcus pyogenes, both un
BACKGROUND: Lung transplantation (LTx) is established as a life-saving treatment in end-stage lung disease. However, long-term survival is hampered by the development of chronic rejection, almost synonymous with bronchiolitis obliterans syndrome (BOS). The rejection is characterized by deposition of extracellular matrix in small airways. Fibroblasts/myofibroblasts are the main producers of extrace
Diagnosis of primary hepatocellular carcinoma (HCC) at early stages has obviously been improved since determination of serum levels of free alpha-fetoprotein (AFP) was implemented. AFP has been considered as the standard tumor marker of primary HCC, although certain patients have very low serum free AFP levels. In the present study, clinical application of measuring serum AFP-IgM immune complexes
PURPOSE Cancer of unknown primary (CUP) is diagnosed at the metastatic stage, and despite extensive diagnostic work-up, the primary tumor often remains unidentified. No data are available on familial clustering of CUP. We hypothesize that familial clustering of CUP with other cancers may be informative of the primary sites. PATIENTS AND METHODS A total of 35,168 patients with CUP were identified i
OBJECTIVE: To evaluate whether features of radiographic hand osteoarthritis (OA) are associated with quantitative magnetic resonance imaging (MRI)-defined knee cartilage thickness, radiographic knee OA, and 1-year structural progression. METHODS: A total of 765 participants in Osteoarthritis Initiative (OAI; 455 women, mean age 62.5 yrs, SD 9.4) obtained hand radiographs (at baseline), knee radi
This paper explores whether women can become the change agents for a sustainable transport sector and how such a change can be accomplished through transport policy. Based on the Swedish case, women still on average have transportation behaviour with lower environmental impact than men have; women also tend to have stronger preferences for improving sustainability in the sector. The results imply
Summary The serum resistance of the common respiratory pathogen Moraxella catarrhalis is mainly dependent on ubiquitous surface proteins (Usp) A1 and A2 that interact with complement factor 3 (C3) and complement inhibitor C4b binding protein (C4BP) preventing the alternative and classical pathways of the complement system respectively. UspA2 also has the capacity to attract vitronectin that in tur
POU5F1 has two alternatively spliced transcripts: a long (variant 1, NM_002701) and a short (variant 2, NM_203289) transcript. Only variant 1 is a key regulator of pluripotency. Hence, it is important to be able to distinguish this transcript from variant 2 and from the many pseudogenes present in the genome. Previous studies on the expression of POU5F1 were, however, usually carried out without c
All over Sweden it has since long been possible to follow authors as well as fictional characters in their footsteps, inspired by books and filmic adaptations. The opportunities have increased and there is a growing market for trips of this kind. In its organized form these activities are part of something much larger, including an economic development where economic and cultural spheres increasin
