State-of-the-art review on timber connections with glued-insteel rods

Adhesive joints have been known andapplied for timber structures for decades. Hybridjoints with glued-in rods are nowadays successfullyused for both constructing new and strengtheningexisting timber structures. Since the 1980s theresearch and development of timber joints withbonded-in rods have been going on, however agreementregarding design criteria for these connectionshas not been reached. Tod

Reduction in ground vibrations by using shaped landscapes

Reduction in traffic-induced ground vibrations by the use of shaped landscapes is investigated here by shaping the landscape surrounding a high-tech facility, using the landscape thus produced as a wave obstacle. The effects of the geometric parameters of a shaped landscape were examined in parametric studies. An architectural landscape design was also investigated in terms of its effectiveness in

Fine-particle emissions from solid biofuel combustion studied with single-particle mass spectrometry: Identification of markers for organics, soot, and ash components

The effects of combustion phase and fuel on smoke particle emissions from a wood stove operated with three different wood fuels and from a corn stove were investigated. A single-particle mass spectrometer (aerosol time of flight mass spectrometer (ATOFMS)) was used for time-and size-resolved chemical signatures and a scanning mobility particle sizer (SMPS) was used for online mobility size distrib

Tomato Thymidine Kinase Is Subject to Inefficient TTP Feedback Regulation.

A promising suicide gene therapy system to treat gliomas has been reported: the thymidine kinase 1 from tomato (toTK1) combined with the nucleoside analog pro-drug zidovudine (azidothymidine, AZT), which is known to penetrate the blood-brain barrier. Transduction with toTK1 has been found to efficiently increase the sensitivity of human glioblastoma cells to AZT, and nude rats with intracranial gl

Altered nociceptive C fibre input to primary somatosensory cortex in an animal model of hyperalgesia.

Evaluating potentially analgesic effects of drugs and various treatments is critically dependent on valid animal models of pain. Since primary somatosensory (SI) cortex is likely to play an important role in processing sensory aspects of pain, we here assess whether monitoring SI cortex nociceptive C fibre evoked potentials can provide useful information about central changes related to hyperalges

How to Handle Genetic Information: A Comparison of Attitudes among Patients and the General Population

Background: So far there are no studies comparing the attitudes of patients with hereditary conditions to the attitudes of the general public on how to handle genetic risk information which mutation carriers refuse to disclose to relevant family members. The purpose of the present study was to investigate whether such patients and members of the general public want to be informed about the existen

Thin electron beam defined hydrogen silsesquioxane spacers for vertical nanowire transistors

A method to fabricate inorganic vertical spacer layers with well-controlled thickness down to 40 nm using electron beam exposure is demonstrated. These spacers are suitable in vertical nanowire transistor configuration. As spacer material, the authors use hydrogen silsesquioxane (HSQ), a material with low permittivity and high durability. They show that the resulting HSQ thickness can be controlle

Distance, proximity and types of cross-border innovation systems: A conceptual analysis

Abstract in French À cause d'un manque de recherche empirique à la fois théorique et systématique, les processus d'intégration déterminés par l'innovation dans les zones transfrontalières sont toujours mal compris. S'éloignant de l'approche des systèmes régionaux d'innovation, de la recherche récente sur la proximité, et de la documentation sur les zones transfrontalières, cet article cherche à idDue to a lack of both theoretical and systematic empirical work, innovation-driven integration processes in cross-border areas are still poorly understood. Departing from the regional innovation system (RIS) approach, recent work on different forms of proximity, and the literature on cross-border areas, this paper seeks to identify in a conceptual way different stages in the development of cross-b

POMC and TP53 genetic variability and risk of basal cell carcinoma of skin: Interaction between host and genetic factors

Background: Basal cell carcinoma (BCC) of the skin is the most common neoplasm among the Caucasian population of the western world. Ultraviolet (UV) radiation-induced p53 activation promotes cutaneous pigmentation by increasing transcriptional activity of pro-opiomelanocortin (POMC) in the skin. Induction of POMC/alpha-melanocyte-stimulating hormone (alpha-MSH) activates the melanocortin 1 recepto

High-mobility group box protein 1 and its signalling receptors in human preterm and term cervix

The objective of this study was to identify possible changes in mRNA and protein expression of high-mobility group box protein 1 (HMGB1) and its suggested receptors - receptor for advanced glycation end-products (RAGE) and Toll-like receptor 2 (TLR2) and TLR4 - in human cervix during pregnancy, term and preterm labor. Cervical biopsies were taken from 58 women: 20 at preterm labor, 24 at term labo

Metabolic risk factors and primary liver cancer in a prospective study of 578,700 adults

Initial studies have indicated diabetes and obesity to be risk factors for hepatocellular carcinoma; but the association between other metabolic risk factors and primary liver cancer (PLC) has not been investigated. The metabolic syndrome and cancer project (Me-Can) includes cohorts from Norway, Austria and Sweden with data on 578,700 subjects. We used Cox proportional hazard models to calculate r

Systematic evaluation of non-animal test methods for skin sensitisation safety assessment.

The need for non-animal data to assess skin sensitisation properties of substances, especially cosmetics ingredients, has spawned the development of many in vitro methods. As it is widely believed that no single method can provide a solution, the Cosmetics Europe Skin Tolerance Task Force has defined a three-phase framework for the development of a non-animal testing strategy for skin sensitisatio

G Protein-coupled Receptor 30 (GPR30) Forms a Plasma Membrane Complex With Membrane-associated Guanylate Kinases (MAGUKs) and AKAP5 That Constitutively Inhibits cAMP Production.

GPR30, or G protein-coupled estrogen receptor (GPER), is a GPCR reported to bind 17β-estradiol (E2), couple to the G proteins Gs and Gi/o, and mediate non-genomic estrogenic responses. However, controversies exist regarding the receptor pharmacological profile, effector coupling, and subcellular localization. We addressed the role of the type I PSD-95/Discs-large/ZO-1 homology (PDZ) motif at the r

Holocene environmental changes in southern Kamchatka, Far Eastern Russia, inferred from a pollen and testate amoebae peat succession record

High resolution palaeoenvironmental records in Far-Eastern Russia are rare, and the Kamchatka Peninsula is among the least studied areas of the region. This paper describes a record spanning the last ca. 11,000 yr, obtained from a bog in the southern part of Kamchatka. The radiocarbon dated core was analysed for pollen, testate amoebae, charcoal and loss-on-ignition (LOI). The vegetation during th

Experimental testing of load-bearing timber–glass composite shear walls and beams

The paper presents results from the experimental testing of load-bearing timber–glass composite shear walls and beams. Shear wall specimens measuring 1200 × 2400 mm2 manufactured with three adhesives of varying stiffness were tested. Twelve specimens with a single 10 mm thick glass pane and one specimen with an additional insulating glass unit were produced. The testing procedures involved various

European Stroke Organisation (ESO) guidelines for the management of spontaneous intracerebral hemorrhage

BackgroundIntracerebral hemorrhage (ICH) accounted for 9% to 27% of all strokes worldwide in the last decade, with high early case fatality and poor functional outcome. In view of recent randomized controlled trials (RCTs) of the management of ICH, the European Stroke Organisation (ESO) has updated its evidence-based guidelines for the management of ICH. MethodA multidisciplinary writing committee

Circulating triacylglycerol signatures and insulin sensitivity in NAFLD associated with the E167K variant in TM6SF2

Background & Aims: The Glu167Lys (E167K) variant in the transmembrane 6 superfamily member 2 protein (TM6SF2) was recently shown to influence liver fat (LFAT) content. We aimed at studying how this variant influences circulating triacylglycerol (TAG) signatures and whether it influences hepatic or adipose tissue insulin sensitivity. Methods: We genotyped 300 Finnish subjects for the E167K (rs5
