The assessment of remediation on metal-polluted soils is usually focused on total and/or bioavailable metal content. However, these chemical variables do not provide direct information about reductions in heavy metals pressure on soil microorganisms. We propose the use of bacterial communities to evaluate the efficiency of three remediation techniques: crushed mussel shell (CMS) and pine bark (PB)

There is a strong association across countries between proxies of transparency, such as absence of corruption, freedom of the press, or information disclosure by public bodies, and standard measures of economic development. This says little about whether more transparency actually leads to better economic outcomes - first, because transparency is difficult to fully disentangle from other broad cha

Objective. To study degree of blood pressure (BP) control in primary healthcare (PHC) treated hypertensive patients in relation to sex, age, drug treatment, and concomitant diseases. Design. Random sample of patients with hypertension. Setting. Ten PHC centres in the Region of Skane, Sweden. Subjects. All the 30- to 95-year-old patients with hypertension who during the period 12 September to 24 Se

A novel method of indirect deposition by means of a focused ion beam (FIB) is utilized to develop metal/insulator/semiconductor nanowire core-shell structures. This method is based upon depositing an annular pattern centered on a nanowire, with secondary deposition then coating the wire. Typical cross-sectional deposition area increments as a function of ion doses are 1.3 x 10(-2) mu m(2) nC(-1) f

Popular Abstract in Swedish När ett barn föds före graviditetsvecka 30 är andningsinsufficiens eller på engelska kallad respiratory distress syndrome (RDS) ett av de stora kliniska problemen som barnläkaren står inför. Redan på 1920-talet förstod man att det måste finnas ett ytspänningsnedsättande ämne i lungorna och på 1950-talet fann man att för tidigt födda (prematura) barn med RDS hade brist pUsing an animal model, the thesis explores how the initial ventilation of the lungs, and surfactant therapy, should best be managed after premature birth. Material and measurements: The studies were made in newborn lambs delivered by cesarean section. Spread of exogenous surfactant was analysed by mixing it with technetium-labelled macroaggregated human serum albumin and imaging the radioactivity

The Nordic Grid facility (NorduGrid [1]) came into operation during summer 2002 when the Scandinavian ATLAS HEP group started to use the Grid for the ATLAS Data Challenges (DC) and was thus the first Grid ever contributing to an ATLAS production. Since then, the Grid facility has been in continuous 24/7 operation. NorduGrid is being used by a growing set of active users from various scientific are

BACKGROUND AND AIMS: Leukocyte recruitment is a key feature in ischemia-reperfusion (I/R)-induced tissue injury. The aim of the present study was to investigate the effect of Rho-kinase inhibition on I/R-provoked leukocyte recruitment in the colon. METHODS: C57BL/6 mice were subjected to 30 min of ischemia by clamping of the superior mesenteric artery followed by 120 min of reperfusion. Intraperit

Background: Stroke is one of the leading causes of death, and out of all stroke cases, 10-15% originate from a previously asymptomatic stenosis in the internal carotid artery. Aims: The aim of the study was to investigate whether dietary and lifestyle habits were associated with future risk of incident carotid artery disease (CAD). Methods: Baseline examinations on middle-aged individuals (n = 30,

Climate variability is highly impacting on mosquito-borne diseases causing malaria and dengue fever across the globe. Seasonal variability change in temperature and rainfall patterns are impacting on human health. Mosquitoes cause diseases like dengue fever, yellow fever, malaria, Chikungunya, West Nile and Japanese encephalitis. According to estimations by health organizations, annually one milli

BACKGROUND: The locoregional failure rate remains high in advanced cervical carcinoma. Chemotherapy (CT) was added to radiotherapy (RT) in order to increase disease control and to improve 5-year survival.METHODS: CT + RT included cisplatin administered 100mg/m2, d.1 plus 5-fluorouracil 1000 mg/m2 D.1 to 5, ci (120 hrs), q every 3rd week for 3 cycles, followed by RT. RT included external beam irrad

Although atmospheric 222radon (222Rn) activity concentration measurements are currently performed worldwide, they are being made by many different laboratories and with fundamentally different measurement principles, so compatibility issues can limit their utility for regional-to-global applications. Consequently, we conducted a European-wide 222Rn ∕ 222Rn progeny comparison study in order to eval

We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200

The inorganic metal or metal-oxide nanoparticles (NPs) that mimic enzymes are of great interest due to improved physical and chemical properties compared with native enzymes. Here, we report that manganese dioxide (MnO2)-Silk exhibit catalase, oxidase, and peroxidase-like activities. The MnO2-Silk hybrid fibers effectively decomposed hydrogen peroxide (H2O2) and oxidized the typical horseradish pe

Phosphodiesterase type 3B (PDE3B) has been shown to be activated and phosphorylated in response to insulin and hormones that increase cAMP. In order to study serine/threonine protein phosphatases involved in the regulation of rat adipocyte PDE3B, we investigated the phosphorylation and activation of PDE3B in vivo in response to phosphatase inhibitors and the dephosphorylation and deactivation of P

Superporous agarose beads contain two sets of pores, diffusion pores and so-called superpores or flow pores, in which the chromatographic flow can transport substances to the interior of each individual bead [Gustavsson and Larsson, J. Chromatogr. A 734 (1996) 231]. The existence of pore flow may be proven indirectly by the chromatographic performance of beads but it has never been directly demons

Secondary metabolites produced by fungi and bacteria are among the potential agents that contribute to adverse health effects observed in occupants of buildings affected by moisture damage, dampness and associated microbial growth. However, few attempts have been made to assess the occurrence of these compounds in relation to moisture damage and dampness in buildings. This study conducted in the c

We used the in vitro regenerating frog sciatic nerve to look for effects of insulin and insulin-like growth factors I and II (IGF-I, IGF-II) on regeneration of sensory axons and on injury induced support cell proliferation in the outgrowth region. In nerves cultured for 11 days, a physiological dose (10 ng/ml, ≈ nM) of insulin or IGF-II increased ganglionic protein synthesis (by 20% and 50%, respe
