The development of fungal biomass and increase of amounts of N was studied in decomposing pine needle litter for about 3 yr. After a relatively rapid increase of the amount of mycelium the fungal biomass became rather constant after about 2 yr. The absolute amount of N in the needles increased between the 4th and the 16th months and this increase was correlated to the increase of fungal biomass in
The aim of this work was to characterize the effect of experimental diabetes on neurotransmission in rat vagina. Female Sprague-Dawley rats were divided into two groups: non-diabetic controls (NDM, n=38) and diabetics (DM, n=38). DM was produced by intraperitoneal injection of streptozotocin. Eight weeks later the animals were killed, the distal part of the vagina was removed, and smooth muscle st
Neuropathic pain is a common consequence of damage to the nervous system. We here report a genetic analysis of development of neuropathic pain-like behaviors after unilateral photochemically-induced ischemic sciatic nerve injury in a panel of inbred rat strains known to display different susceptibility to autoimmune neuroinflammation. Pain behavior was initially characterized in Dark-Agouti (DA; R
Objective: To develop a short measure of physical function for knee osteoarthritis (OA) using multi-national data from. individuals with varying degrees of severity of knee OA. Methods: Rasch analysis, based on the partial credit model, was conducted on Knee injury and Osteoarthritis Outcome Score and Western Ontario McMaster Universities' Osteoarthritis Index data from individuals with knee OA, r
Birth characteristics and growth pattern in 76 children with congenital cytomegalovirus (CMV) infection were compared to Swedish reference data. Infection classification was based on maternal sera during pregnancy. In 31 children the infection was primary and 31 children had reactivated (recurrent or secondary) congenital CMV infection. Infection type could not be determined in 14 children. Transi
In a prospective study comprising 310 consecutive patients with carcinoma of the cervix, FIGO stages I-IV, the prognostic significance of clinical and flow cytometric variable was evaluated in a univariate and multivariate analysis. The parameters studied included stage according to FIGO, age, histopathologic grade according to Ackerman and MGS scores, DNA ploidy, S-phase fraction as well as treat
An investigation combining IR spectroscopy, potentiometric titrations, and adsorption experiments was carried out to study pyromellitate (1,2,4,5-benzenetetracarboxylate) sorption at the goethite (alpha-FeOOH)/ water interface. The IR spectra show evidence of outer-sphere complexation throughout the pH range from 3 to 9. Below pH 6 additional IR spectroscopic features appear, which are tentatively
Diverticulitis causes recurrent abdominal pain associated with increased mucosal expression of mucosal galanin and substance P (SP). We studied changes in mucosal and myenteric plexus neuropeptides in adult rats using a model of colonic inflammation, trinitrobenzenesulphonic acid colitis. We assessed the effects on the pan-neuronal markers protein gene product 9.5 (PGP9.5) and neurofilament protei
objectives To assess effects of GH replacement therapy on cardiac structure and function, exercise capacity as well as serum lipids in elderly patients with GH deficiency (GHD). patients and methods Thirty-one patients (six females, 25 males), aged 60-79 years (mean 68 years) with GHD on stable cortisone and thyroxine substitution were studied. All men with gonadotropin deficiency had testosteron
We analyse time series data of 17 bird species trapped at Ottenby Bird Observatory, Sweden, during spring migration 1972-1999. The species have similar demography but respond differently to variation in the North Atlantic Oscillation (NAO) - a strong determinant of winter climate in the northern Hemisphere. Species wintering in northern Europe, compared to species having winter quarters in the Med
BACKGROUND: The aim of this study was to evaluate and compare the cost-effectiveness of varenicline with nicotine replacement therapy (NRT) for smoking cessation in four European countries (Belgium, France, Sweden and the UK). METHODS: Markov simulations, using the Benefits of Smoking Cessation on Outcomes (BENESCO) model, were performed. We simulated the incidence of four smoking-related morbidit
We consider the problem of how to schedule t similar and independent tasks to be performed in a synchronous distributed system of p stations communicating via multiple-access channels. Stations are prone to crashes whose patterns of occurrence are specified by adversarial models. Work, defined as the number of the available processor steps, is the complexity measure. We consider only reliable algo
Prostate cancer is the most common malignancy of men in Western countries. Patients with advanced prostate cancer suffer from incurable bone metastases. Recent data indicate that interactions between prostate cancer cells, osteoblasts, osteoclasts and the bone matrix are essential in the formation of bone metastases. FGF-8 is widely overexpressed in prostate cancer. Recently, FGF-8 has been found
Based on a large number of new boreholes in northern Denmark, and on the existing data, a revised event-stratigraphy is presented for southwestern Scandinavia. Five significant Late Saalian to Late Weichselian glacial events, each separated by periods of interglacial or interstadial marine or glaciolacustrine conditions, are identified in northern Denmark. The first glacial event is attributed to
Lignin was extracted by ultrafiltration from kraft cooking liquors taken directly from a continuous digester. The temperature of the liquors was 145 degrees C (softwood) or 135 degrees C (hardwood), the total dry solids content was 18% and the pH 13-14. Methods for start-up, shut-down and cleaning of conventional UF equipment modified for this demanding application, were developed. The influence o
Aim: To study the effects of alcohol and coping intervention among University students who have parents with alcohol problems. Methods: A total of 82 university students (56 women and 22 men, average age 25) with at least one parent with alcohol problems were included. The students were randomly assigned to one of three programs: (i) alcohol intervention program, (ii) coping intervention program,
This paper discusses narratives of polar adventure tourism from a multidisciplinary perspective of play. Reviewing discussions on the motivation behind this subject, it examines two concurrent approaches in particular: risk and insight theories. Based on empirical evidence obtained from a winter trekking trip to an Artic tourism destination, the paper argues that these theories may be particular c
