Five things you need to know about prostate cancer diagnostic tests

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

BTKbase: the mutation database for X-linked agammaglobulinemia.

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

Intracranial haemorrhage in haemophilia A and B.

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

High-order Harmonic-generation Cutoff

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 and its role in CNS disease and repair.

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, color, and contest success in the jumping spider Lyssomanes viridis

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

Revisiting the Healthy Migrant Paradox in Perinatal Health Outcomes Through a Scoping Review in a Recent Host Country.

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

Constitutive expression of the antibacterial CXC chemokine GCP-2/CXCL6 by epithelial cells of the male reproductive tract.

The reproductive tract is continuously challenged by potential pathogens present in the environment. Therefore, robust host defense mechanisms are essential both for the health of the individual and for fertilization. Antibiotic innate immunity peptides possess broad antimicrobial activity. Recently, we found that the CXC chemokine, granulocyte chemotactic protein (GCP)-2/CXCL6, possesses antibact

Socioeconomic Position, Comorbidity, and Mortality in Aortic Aneurysms: A 13-Year Prospective Cohort Study.

BACKGROUND: To evaluate factors associated with incidence and 3-year all-cause mortality in patients with aortic aneurysm (AA). The design is sex and age-stratified (60-79 and 80-90 years) prospective cohort. By using the population register, we constituted a cohort of all men and women born between 1900 and 1930 and living in Scania by 1991, and followed them for 13 years. Identification of AA wa

Covert bilingualism and symbolic competence: Analytical reflections on negotiating insider/outsider positionality in Swedish speech situations

Bilinguals often face the challenge of negotiating a range of insider/outsider subject positions when interacting in transnational and intercultural settings. This article takes up the concept of symbolic competence, the awareness of socially situated symbolic resources and the ability to use them to shape interactional contexts, to examine how the author, a Swedish–English bilingual, manages this

Deficiencies in DNA damage repair limit the function of haematopoietic stem cells with age

A diminished capacity to maintain tissue homeostasis is a central physiological characteristic of ageing. As stem cells regulate tissue homeostasis, depletion of stem cell reserves and/or diminished stem cell function have been postulated to contribute to ageing. It has further been suggested that accumulated DNA damage could be a principal mechanism underlying age-dependent stem cell decline. We

Distribution of melatonin receptors in murine pancreatic islets.

Melatonin has multiple receptor-dependent and receptor-independent functions. At the cell membrane, melatonin interacts with its receptors MT1 and MT2, which are expressed in numerous tissues. Genome-wide association studies have recently shown that the MTNR1B/MT2 receptor may be involved in the pathogenesis of type 2 diabetes mellitus. In line with these findings, expression of melatonin receptor

Manipulating the anabolic and catabolic response in bone graft remodeling: Synergism by a combination of local BMP-7 and a single systemic dosis of zoledronate.

Remodeling of a bone graft can be influenced both by anabolic substances, such as a bone morphogenic protein (BMP) and by anticatabolic substances, such as the bisphosphonates. BMPs are potent bone anabolic substances, but also boost catabolism and cause resorption. Bisphosphonates inhibit osteoclast function and can be used to postpone resorption. In the present study a combination of both drugs

Shaping discourses of multilingualism through a language ideological debate: The case of Swedish in Finland

The ideological (re)construction of the position of Swedish in Finland is examined as it took shape during a major year-long debate about the role of Swedish in Finnish education. Data were collected through archival research of the leading national newspapers in the two official languages of Finland: Helsingin Sanomat (Finnish) and Hufvudstadsbladet (Swedish). Circulating and intersecting discour

Observing strain localisation processes in bio-cemented sand using x-ray imaging

In-situ x-ray tomography has been used to follow deformation processes in 3D during two triaxial compression tests, one on a specimen of bio-cemented Ottawa 50-70 sand and the other on a specimen of the non-cemented sand. The global stress-strain responses show that the bio-cementation process increases the shear strength (peak deviator stress is approximately doubled), and causes the material to
