J Periodont Res 2010; doi: 10.1111/j.1600-0765.2010.01331.x. © 2010 John Wiley & Sons A/S Background: Periodontal ligament cells are fibroblast-like cells characterized by collagen production but also possessing some osteoblastic features. In the light of numerous

Objectives: To explore and gain insight into factors related to self-rated health (SRH) among very old people in two European countries. Methods: The study was based on Latvian (n = 301) and Swedish (n = 397) data from the baseline of the Enabling Autonomy, Participation, and Well-Being in Old Age: The Home Environment as a Determinant for Healthy Ageing Survey Study. Besides descriptive statistic

A search for the lepton flavour violating processes ep→μX and ep→τX is performed with the H1 experiment at HERA. Final states with a muon or tau and a hadronic jet are searched for in a data sample corresponding to an integrated luminosity of 66.5 pb-1 for e+p collisions and 13.7 pb-1 for e-p collisions at a centre-of-mass energy of 319 GeV. No evidence for lepton flavour violation is found. Limit

During recent years, several spectacular collapses happened in large timber structures and the question is what can be done to prevent future failures. The main hypothesis for this project has been that quality assurance, control systems and improved training may be necessary, since the unwanted events are primarily related to human errors. A survey of failures in 127 timber structures has been ma

For many years, prostate cancer early detection was a straightforward matter of recommending biopsy to all men with an elevated prostate-specific antigen (PSA). This is perhaps best evidenced by the European Randomized Trial of Screening for Prostate Cancer, where an automatic biopsy is specified in the protocol and close to 90% of men with a PSA ≥3.0 ng/mL were biopsied [1]. Starting around 2010,

Le philosophe Jean-François Lyotard fut invité en 1983 par le Centre de création industrielle (CCI) à rejoindre le projet d’une manifestation qui s’ouvrirait finalement deux ans plus tard. Intitulée « Les Immatériaux », elle allait constituer un jalon majeur dans l’histoire des expositions au xxe siècle. Appelé en tant que commissaire principal, Lyotard fit néanmoins le choix de s’acquitter de sa

X-linked agammaglobulinemia (XLA) is a hereditary immunodeficiency caused by mutations in the gene encoding Bruton tyrosine kinase (BTK). XLA patients have a decreased number of mature B cells and a lack of all immunoglobulin isotypes, resulting in susceptibility to severe bacterial infections. XLA-causing mutations are collected in a mutation database (BTKbase), which is available at http://bioin

In countries with a good standard of health care, intracranial haemorrhage (ICH) during the neonatal period affects 3.5-4.0% of all haemophilia boys, which is considerably (40-80 times) higher than expected in the normal population. ICHs are also frequent after the neonatal period, affecting 3-10% of the haemophilia population who are mainly treated on demand. The risk is higher in inhibitor patie

We have experimentally determined the harmonic-generation cutoff as a function of the laser intensity in neon using an intense, short-pulse Ti:sapphire laser. The experimental cutoff is lower than that obtained in single-atom calculations. Using a simple quantum-mechanical approach to harmonic generation valid at high intensity, we show that the difference is due to the effect of propagation.

Neuropeptide Y (NPY) is widely expressed throughout the CNS and exerts a number of important physiological functions as well as playing a role in pathological conditions such as obesity, anxiety, epilepsy, chronic pain and neurodegenerative disorders. In this review, we highlight some of the recent advances in our understanding of NPY biology and how this may help explain not only its role in heal

Weaponry and color badges are commonly theorized to function as visual signals of aggressiveness or fighting ability. However, few studies have supported a signaling function of weaponry, and the role of color in invertebrate competitive interactions remains virtually unexplored. Jumping spiders (Salticidae) make excellent invertebrate models for studying weaponry and color because males of many s

Ample evidence shows that, in many developed countries, immigrants have similar or better perinatal health outcomes than natives despite facing socioeconomic disadvantages in the host country ("healthy migrant paradox" -HMP). This scoping review aims to: (1) summarize the literature on perinatal health among immigrants and natives in Spain and (2) examine whether there is evidence of the HMP in a
