It is hard to defend the view that biotic communities represent a simple and predictable response to the abiotic environment. Biota and the abiotic environment interact, and the environment of an individual certainly includes its neighbors and visitors in the community. The complexity of community assembly calls forth a quest for general principles, yet current results and theories on assembly rul
Our study had three objectives: to extend the plasmid-based transformation protocol to a clinical isolate of C. trachomatis belonging to the trachoma biovar, to provide "proof of principle'' that it is possible to "knock out'' selected plasmid genes (retaining a replication competent plasmid) and to investigate the plasticity of the plasmid. A recently developed, plasmid-based transformation proto
Renal function is often estimated using one of several glomerular filtration rate (GFR) estimating equations. However, there is no consensus which estimating equation performs best in patients with advanced renal failure. We compared the performance of five different estimated GFR (eGFR) equations [Cockcroft-Gault, Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease (CKD) Epidemio
Popular Abstract in Swedish Den viktigaste uppgiften inom den kliniska cytologin är att påvisa cancerceller i olika typer av cellprover. Många olika cancertumörer sprider sig till lungsäcken och bukhålan och ger då ofta upphov till vätska (exsudat) som innehåller cancerceller. Ofta kan cancerdiagnosen ställas på grundval av cellernas utseende men detta är inte alltid möjligt, eftersom cancercellerClinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. It is the most promising universal indicator of malignancy and the project focuses o
Objectives: To investigate determinants of joint destruction and reduced bone mineral density (BMD) in postmenopausal women with active rheumatoid arthritis (RA) not treated with bisphosphonates or hormone replacement therapy and to evaluate if there are common markers of erosive disease and bone loss. Methods: BMD was measured using dual x ray absorptiometry and joint damage was examined by x ra
We present measurements of isothermal DNA-hexadecyltrimethylammonium (DNACTA) complex and pure DNA hydration at 25 degreesC using a sorption microcalorimeter. This calorimeter provides simultaneous measurement of (i) water activity (sorption isotherms) and (ii) the partial molar enthalpy of water as a function of water uptake. For pure DNA, hydration is exothermic over the studied concentration ra
Through several decades of research, absolute paleointensity estimates have been obtained from a wide range of rocks with varying ages, covering the last 3.45 Ga years. These paleointensity data are crucial to study the past geodynamo and the geological evolution of the Earth's deep interior. However, paleointensity data are often difficult to interpret, and on-going discussions concerning the pas
That the Church of Norway has now adopted gender equality as its policy, is a new situation in a historical perspective, and is the result of a long process within the framework of the state church system. In this context, the way in which the Storting (the Norwegian parliament) dealt with the issue of admitting women to clerical offices in the 1930s was important. The purpose of this thesis has b
Popular Abstract in Swedish Vi kan inte avslöja innehållet i våra tankar direkt, så hur kan vi närma oss de underliggande kognitiva processerna? Om vi vill lära oss mer om vad som försiggår i vår tankevärld, måste vi göra det indirekt, med hjälp av tankarnas yttre manifestationer. Det finns olika metoder som man kan ta till sin hjälp. I min avhandling kopplar jag ihop två ämnesområden, lingvistik In this thesis, I connect two disciplines, linguistics and vision research, and combine two methods, spoken language protocols and eye movement protocols, in order to cast light on the underlying cognitive processes. In a series of studies, I investigate the processual aspects of picture viewing and picture description. On the one hand, eye movements reflect human thought processes. It is easy to
OBJECTIVES: Previous studies have shown that patients with diabetes mellitus have an increased mortality after suffering from acute myocardial infarction (AMI). Patients with diabetes have several risk factors for cardiovascular disease. Our objective was to quantify the prevalence of pharmacological cardiovascular prevention at admission and relate such treatment to short and long-term mortality
Background: A trial fibrillation (AF) is a common problem in pacemaker patients. We conducted a prospective observational study in patients paced for bradycardia with associated paroxysmal or persistent AF, to determine whether P-wave duration may stratify patients at higher risk for AF recurrences and AF-related hospitalizations. The patients were evaluated for the prevalence, cause, and predicto
Background: The complexity and dynamical nature of community interactions make modelling a useful tool for understanding how communities develop over time and how they respond to external perturbations. Large community-evolution models (LCEMs) are particularly promising, since they can address both ecological and evolutionary questions, and can give rise to richly structured and diverse model comm
The monosaccharide anhydrides (MAs) levoglucosan, galactosan and mannosan are products of incomplete combustion and pyrolysis of cellulose and hemicelluloses, and are found to be major constituents of biomass burning (BB) aerosol particles. Hence, ambient aerosol particle concentrations of levoglucosan are commonly used to study the influence of residential wood burning, agricultural waste burning
The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct
A comparison between three different types of particle sizing instruments (fast mobility particle sizer, FMPS; electrical low pressure impactor, ELPI; and scanning mobility particle sizer, SMPS) and one condensation particle counter (CPC) was made to compare instrument response in terms of size distributions and number concentration. Spherical oil droplets in 39 different sizes, with geometric mea
In enology, "Brett" character refers to the wine spoilage caused by the yeast Dekkera/Brettanomyces bruxellensis and its production of volatile phenolic off-flavours. However, the spoilage potential of this yeast is strain-dependent. Therefore, a rapid and reliable recognition at the strain level is a key point to avoid serious economic losses. The present work provides an operative tool to assess
Currently available research suggests that negative pressure wound therapy (NPWT) creates a moist wound healing environment, drains exudate, reduces tissue edema, contracts the wound edges, mechanically stimulates the wound bed, and influences blood perfusion at the wound edge, which may lead to angiogenesis and the formation of granulation tissue. Although no clear evidence is available that NPWT
All women in the South Sweden Health Care Region with breast cancer diagnosed aged less than 41 during the period between 1990 and 1995 were contacted in 1996 and offered germline mutation analysis of the BRCA1 and BRCA2 genes. Mutation carriers (n = 20) were compared with noncarriers (n = 201) for overall survival (OS) and risk of contralateral breast cancer (CBC). Mutation carriers were younger
Infertility affects 15% of all couples. Although male infertility factors with reduced semen quality are contributing to about half of all involuntary childlessness, the value of standard semen parameters in prediction of fertility in vivo and choice of proper method for assisted reproduction is limited. In the search for better markers of male fertility, during the last 10 years, assessment of sp
