Variation in host specificity and gene content in strains from genetically isolated lineages of the ectomycorrhizal fungus Paxillus involutus s. lat.

Ectomycorrhizal fungi are known to vary in host range. Some fungi can enter into symbiosis with multiple plant species, while others have restricted host ranges. The aim of this study was to examine variation in host specificity among strains from the basidiomycete Paxillus involutus s. lat. Recent studies have shown that this fungus consists of at least four genetically isolated lineages, phyloge

Inductive pointing device for tongue control system for computers and assistive devices

Experimental results for pointing tasks using a tongue control system are reported in this paper. Ten untrained subjects participated in the experiment. Both typing and pointing tasks were performed, in three short-term training sessions, in consecutive days, by each subject. The system provided a key pad (14 sensors) and a mouse pad (10 sensors with joystick functionality) whose placements were i

Intensive glucose therapy and clinical implications of recent data: a consensus statement from the Global Task Force on Glycaemic Control

Background: There is compelling evidence showing that achieving good glycaemic control reduces the risk of microvascular complications in people with type 1 and type 2 diabetes. Likewise, there is clear evidence to show that achieving good glycaemic control reduces the risk of macrovascular complications in type 1 diabetes. The UKPDS 10-year follow up suggests that good glycaemic control also redu

Rutinmässig rektalpalpation vid akut buk har inget visat värde. En genomgång av litteraturen.

I klinisk praxis görs palpation per rektum rutinmässigt på vuxna patienter vid akut buk. Vi utvärderade evidensen för detta genom en systematisk litteratursökning och identifierade 16 relevanta originalstudier. Dessa visade att det saknas evidens för diagnostisk nytta av rektalpalpation vid akut buk, inklusive misstänkt appendicit. Rutinmässig rektalpalpation bör inte göras vid akut buk hos vuxnaA digital rectal examination (DRE) is standard practice in cases of acute abdomen in adult patients. We analyzed the evidence for this by a systematic literature search, and identified 16 relevant original studies. These studies showed that there is no evidence for a diagnostic value of DRE in adult patients with acute abdomen. We should stop doing routine DRE in adult cases of acute abdomen.

A Numerical Study of the Thermal Performance of Microchannel Heat Sinks with Multiple Length Bifurcation in Laminar Liquid Flow

A rectangular, straight microchannel heat sink with multiple length bifurcation has been designed, and the corresponding laminar flow and thermal performance have been investigated, numerically. Five different cases with multiple length bifurcation and various arrangements are investigated, as well as one case without bifurcations. All laminar fluid flow and surface heat transfer results are obtai

Outriggers Lost in the sea of Time: An Overlooked Aspect of Cultural Change and Conditions for Sustainable Development in Oceania

A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res

Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at root s(NN)=2.76 TeV

Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at root s(NN) = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral collisions, corresponding to 0-5% and 70-80% of the hadronic Pb-Pb cross section. The measured charged particle spectra in |eta| < 0.8 and 0.3 < p(T) < 20 GeV/c are compared to the

Mutations and polymorphisms in TP53 gene-an overview on the role in colorectal cancer

A functionally normal TP53 is essential to protect organisms from developing cancer. Somatic mutations in the gene represent one of the highest recurring perturbations in human tumours, including colorectal cancer (CRC). However, the variegated phenotype of wide spectrum of somatic mutations in TP53 and the complexity of the disease prevent a straight interpretation of the mutational analysis in t

Mapping of quantitative trait loci for floral scent compounds in cowpea (Vigna unguiculata L.)

Floral scent is a very important trait in plant evolution. Currently, little is known about the inheritance of floral scent in cowpea (Vigna unguiculata L.) or changes that might have occurred during its domestication. Therefore, we analysed scent volatiles and molecular markers in a population of 159 F7 recombinant inbred lines derived from a cross of a domesticated blackeye cowpea cultivar, ‘524

Crosstalk between Inflammation and Coagulation in Acute Pancreatitis - Experimental and Clinical Studies.

Popular Abstract in Swedish Akut pankreatit (AP) är en inflammation i bukspottskörteln, som oftast utlöses av gallstenssjukdom eller alkoholintag. Varför man får akut pankreatit vet man inte och inte heller varför de flesta patienter återhämtar sig på ett par dagar, medan ca 20 procent drabbas av en betydligt svårare form av sjukdomen. Vid svår AP ses en kraftig inflammatorisk reaktion i hela kropIn various inflammatory conditions a close interplay between inflammation and coagulation is known to exist, where coagulation factor VII (FVII) and tissue factor (TF) are considered to be pivotal players. In this thesis the crosstalk between inflammation and coagulation in acute pancreatitis (AP) has been investigated. The results from the first paper, where active site inactivated FVII (FVIIai)

Organic matter stimulates bacteria and arbuscular mycorrhizal fungi in Bauhinia purpurea and Leucaena diversifolia plantations on eroded slopes in Nepal

Erosion resulting from landslides is a serious problem in mountainous countries such as Nepal. To restore such sites it is essential to establish plant cover that protects the soil and reduces surface erosion. Mycorrhizal fungi growing in symbiosis with plants are essential in this respect because they improve both plant nutrient uptake and soil structure. We investigated the influence of organic

High resolution mapping of peatland hydroperiod at a high-latitude Swedish mire

Monitoring high latitude wetlands is required to understand feedbacks between terrestrial carbon pools and climate change. Hydrological variability is a key factor driving biogeochemical processes in these ecosystems and effective assessment tools are critical for accurate characterization of surface hydrology, soil moisture, and water table fluctuations. Operational satellite platforms provide op

Multiradionuclide evidence for the solar origin of the cosmic-ray events of ᴀᴅ 774/5 and 993/4.

The origin of two large peaks in the atmospheric radiocarbon ((14)C) concentration at AD 774/5 and 993/4 is still debated. There is consensus, however, that these features can only be explained by an increase in the atmospheric (14)C production rate due to an extraterrestrial event. Here we provide evidence that these peaks were most likely produced by extreme solar events, based on several new an

Music, lust and modernity: Jazz in the films of Ingmar Bergman

This article explores the recurrent use of jazz music in some of the early films of the Swedish film director Ingmar Bergman: Kris/Crisis (1946), Till glädje/ To Joy (1949), Sommaren med Monika/Summer with Monika (1953), En lektion i kärlek/A Lesson in Love (1954), Kvinnodröm/Dreams (1955) and Tystnaden/The Silence (1963). In these films jazz is presented as derived from the corporeal body, as pow

Ventilated rainscreen cladding: A study of the ventilation drying process

The air exchange in rainscreen walls is expected to provide ventilation drying if excess moisture is absorbed in the wall construction. In an earlier paper, we presented a cavity airflow model and measurement based estimations of air change rates (ACH) in south-facing experimental walls. Here, focus is on the ventilation drying process and its practical implications. ACH in the experimental walls

Simultaneous heat and moisture transport in porous building materials: evaluation of nonisothermal moisture transport properties

The paper presents a mathematical model for calculating the nonisothermal moisture transfer in porous building materials. The simultaneous heat and moisture transfer problem was modeled. Vapor content and temperature were chosen as principal driving potentials. The coupled equations were solved by a numerical method. An experimental methodology for determining the temperature gradient coefficient

Tassiloa, a new genus in the Teloschistaceae (lichenized ascomycetes)

The new genus Tassiloa, proposed for the American Caloplaca digitaurea-group, is supported by phylogenetic analyses based on ITS and LSU nrDNA-sequences, and 12S SSU mtDNA-sequences. The genus is positioned in the Catenarina-clade in the subfamily Teloschistoideae of the family Teloschistaceae. The genus Tassiloa is described and compared with closely related genera. Two new combinations are propo

Improved estimation of glomerular filtration rate (GFR) by comparison of eGFR(cystatin C) and eGFR(creatinine)

Objective. GFR-prediction equations based upon cystatin C and creatinine have better diagnostic performance in estimating GFR than equations based upon only one of the two markers. The present work concerns in what way a comparison between separate estimations of GFR based upon cystatin C (eGFR(cystatin C)) or creatinine (eGFR(creatinine)) can be used to evaluate the diagnostic performance of a co

Galiellalactone induces cell cycle arrest and apoptosis through the ATM/ATR pathway in prostate cancer cells.

Galiellalactone (GL) is a fungal metabolite that presents antitumor activities on prostate cancer in vitro and in vivo. In this study we show that GL induced cell cycle arrest in G2/M phase, caspase-dependent apoptosis and also affected the microtubule organization and migration ability in DU145 cells. GL did not induce double strand DNA break but activated the ATR and ATM-mediated DNA damage resp
