Organic carbon (C) in lakes originates from two distinct sources-primary production from within the lake itself (autochthonous supply) and importation of organic matter from the terrestrial watershed (allochthonous supply). By manipulating the C-13 of dissolved inorganic C, thereby labeling within-lake primary production, we examined the relative importance of autochthonous and allochthonous C in

Introduction: A state of hypercoagulation and fibrinolytic dysfunction is present in individuals with diabetes, which may contribute to disturbed skin microcirculation and impaired ulcer heating. We have previously reported an improved outcome of chronic diabetic foot ulcers during treatment with dalteparin. In the present study we investigated the effects of dalteparin on skin microcirculation an

Background/Aim: Several studies have described that oxytocin exerts stimulatory or inhibitory effects on gut functions. Recently, mRNA for oxytocin and its receptor was found throughout the entire human gastrointestinal (GI) tract. The aim of this study was to examine the cellular localization and distribution of the corresponding proteins. Material and methods: Full-thickness biopsies from 24 pat

Diagnosing myxoid soft tissue neoplasms can be challenging because of overlapping histologic features. Distinct chromosomal translocations have been identified in several myxoid sarcomas, including t(12;16)(q13;p11) FUS-DDIT3 in myxoid liposarcoma, t(7,-16)(q34;p11) FUS-CREB3L2 in low-grade fibromyxoid sarcoma, and t(9;22)(q31;q12) EWSRINR4A3 in extraskeletal myxoid chondrosarcoma. These recurrent

Bacterial activity was studied in a growth system containing Pinus contorta seedlings inoculated with different mycorrhizal fungi. Nylon nets enabled separation of soil compartments with extramatrical mycorrhizal hyphae from soil compartments with roots and mycelium. In three separate experiments bacterial activity, estimated as thymidine incorporation, was reduced in soils with Paxillus involutus

An association between human herpesvirus 8 (HHV8) and multiple myeloma ( MM) has been reported, though most studies have not confirmed such association. To follow-up on a previous prospective seroepidemiological study, where HHV8 tended to associate with MM risk, we linked five large serum banks in the Nordic countries with the Nordic cancer registries and 329 prospectively occurring cases of MM w

Aim To evaluate the instrument Measure of Processes of Care (MPOC) in a Swedish context. Methods The MPOC consists of 56 questions in the five scales: enabling and partnership; providing general information; providing specific information about the child; co-ordinated and comprehensive care; and respectful and supportive care. The questionnaire was translated into Swedish and distributed to 850 f

Aim: Migration has been suggested to promote large breeding ranges among birds because of the greater mobility of migratory compared to non-migratory species, but migration has also been suggested to restrict breeding ranges because of evolutionary constraints imposed by the genetical migration programme. We aim to investigate the association between migration and the breeding ranges of both land

Two barn swallows (Hirundo rustica) flying in the Lund wind tunnel were filmed using synchronised high-speed cameras to obtain posterior, ventral and lateral views of the birds in horizontal flapping flight. We investigated wingbeat kinematics, body tilt angle, tail spread and angle of attack at speeds of 414ms-1. Wingbeat frequency showed a clear U-shaped relationship with air speed with minima a

A comparative study on the bis(functionalization) of the Troger's base core by aromatic and heteroaromatic groups using palladium-catalyzed cross-coupling reactions is presented. Three different reactions, the Suzuki, Stille, and Negishi couplings, were investigated using Troger's base analogues equally substituted in the 2,8-positions with (HO)(2)B, Bu3Sn and ZnCl groups, respectively, as the met

We have investigated terahertz emission due to dynamical electron transport in wide-miniband GaAs/Al0.3Ga0.7As superlattices. By noting that the time-domain THz emission spectroscopy inherently measures the step-response of the electron system to the bias electric field, the obtained THz spectra were compared with the high-frequency conductivities predicted for miniband transport. Excellent agreem

The aim of the study was to evaluate the effect of both phytohaemagglutinin (PHA) alone, and in combination with alpha-ketoglutaric acid (AKG), on nitrogen elimination via the urinary tract as opposed to the gastrointestinal tract of rats. In experiment I, rats were assigned to one of two experimental groups, (1) Control and (2) PHA, whilst in experiment 2, rats were assigned to one of three exper

The ventilation and carbon dioxide elimination of each lung, and pulmonary arterial pressure, were studied in 17 patients during the early phases of anaesthesia for pulmonary surgery. The patients were ventilated mechanically to moderate hypocapnia. Expired tidal volume and carbon dioxide elimination rate of the lung to be operated on, and of the other lung, were similar in the supine position. Th

The maintenance of genetic variation for infection-related traits is often attributed to coevolution between hosts and parasites, but it can also be maintained by environmental variation if the relative fitness of different genotypes changes with environmental variation. To gain insight into how infection-related traits are sensitive to environmental variation, we exposed a single host genotype of

Modelling of pulverised wood flames in a laboratory vertical furnace was carried out. The aim was to gain deeper understanding of the combustion process and to validate a mathematical model to simulate the process. Pulverised wood combustion involves many different processes such as two-phase flow dynamics, drying and devolatilisation of the particles, oxidation of the volatile and formation and o
