Simvastatin protects against cholestasis-induced liver injury.
Background: Bile duct obstruction is associated with hepatic accumulation of leukocytes and liver injury. The aim of this study was to evaluate the effect of simvastatin on cholestasis-induced liver inflammation and tissue damage. Experimental approach: C57BL/6 mice were treated with simvastatin (0.02 and 0.2 mg.kg(-1)) and vehicle before and after undergoing bile duct ligation (BDL) for 12 h. Leu
Porous protein-based scaffolds prepared through freezing as potential scaffolds for tissue engineering.
Successful tissue engineering with the aid of a polymer scaffold offers the possibility to produce a larger construct and to mould the shape after the defect. We investigated the use of cryogelation to form protein-based scaffolds through different types of formation mechanisms; enzymatic crosslinking, chemical crosslinking, and non-covalent interactions. Casein was found to best suited for enzyma
Improved retinal function after trabeculectomy in glaucoma patients.
PURPOSE: To investigate retinal function after reduction of intraocular pressure (IOP) by filtration surgery in patients with medically uncontrolled glaucoma. METHODS: Eleven patients (11 eyes) with medically uncontrolled glaucoma underwent trabeculectomy. Clinical investigation, visual field (testing with standard automated perimetry (SAP-Humphrey), optical coherence tomography (OCT), full-field
Vibrotactile sense in median and ulnar nerve innervated fingers of men with Type 2 diabetes, normal or impaired glucose tolerance.
Aims To investigate vibrotactile sense (large fibre neuropathy) at different frequencies in index and little fingers (median and ulnar nerves, respectively) of subjects with diabetes, or impaired (IGT) or normal glucose tolerance (NGT). Methods Vibration thresholds (tactilometry at seven frequencies (8, 16, 32, 64, 125, 250 and 500 Hz)) and median nerve function (electrophysiology) were examined i

Subexponential asymptotics for stochastic processes : extremal behavior, stationary distributions and first passage probabilities
Consider a reflected random walk Wn+1 = (W-n +X-n)(+), where X-o, X-1,... are i.i.d. with negative mean and subexponential with common distribution F. It is shown that the probability that the maximum within a regenerative cycle with mean mu exceeds x is approximately mu (F) over bar(x) as x --> infinity, and thereby that max (W-o,..., W-n) has the same asymptotics as max(X-o,...,X-n) as n --> inf
Asthma is more prevalent in elite swimming adolescents despite better mental and physical health.
An increased risk of developing asthma has been reported among swimmers exposed to chloramine in pool arenas. The aim of the present study was to compare the prevalence of asthma and respiratory symptoms among elite aspiring swimmers compared with age-matched controls with different degrees of physical activity. We also aimed to relate these findings to mental and psychosocial factors. One hundred

Mitogen-activated protein kinases in the porcine retinal arteries and neuroretina following retinal ischemia-reperfusion.
PURPOSE: The aim of the present study was to examine changes in the expression of intracellular signal-transduction pathways, specifically mitogen-activated protein kinases, following retinal ischemia-reperfusion. METHODS: Retinal ischemia was induced by elevating the intraocular pressure in porcine eyes, followed by 5, 12, or 20 h of reperfusion. The results were compared to those of the sham- op
Binomial mitotic segregation of MYCN-carrying double minutes in neuroblastoma illustrates the role of randomness in oncogene amplification.
BACKGROUND: Amplification of the oncogene MYCN in double minutes (DMs) is a common finding in neuroblastoma (NB). Because DMs lack centromeric sequences it has been unclear how NB cells retain and amplify extrachromosomal MYCN copies during tumour development. PRINCIPAL FINDINGS: We show that MYCN-carrying DMs in NB cells translocate from the nuclear interior to the periphery of the condensing chr

Methylation and loss of secreted frizzled-related protein 3 enhances melanoma cell migration and invasion.
Wnt signaling is important in development and can also contribute to the initiation and progression of cancer. The Secreted Frizzled Related Proteins (SFRPs) constitute a family of Wnt modulators, crucial for controlling Wnt signaling. Here we investigate the expression and role of SFRP3 in melanoma.
Prevention of surgical site infection in total joint arthroplasty: an international tertiary care center survey.
Prevention strategies are critical to reduce infection rates in total joint arthroplasty (TJA), but evidence-based consensus guidelines on prevention of surgical site infection (SSI) remain heterogeneous and do not necessarily represent this particular patient population.

The escape from the Middle Ages: An escape from the Middle Ages is observed among Medieval archaeologists. The author argues that the etsablishment of Medieval archaeology as a discipline was closely connected to the rise of an urban archaeology. Consequently, the main background to the escape from the Middle Ages is the decline of urban archaeology. In correlation, it might even be seen as an esc
Astma är en systemisk inflammation--inte en lokal sjukdom Bred antiinflammatorisk behandlingsstrategi krävs.
The traditional view of asthma has changed considerably during the last decades. A paradigm shift in our understanding of asthma has turned our focus from the importance of muscle spasm to inflammation. Today asthma is believed to be a central airway inflammatory disorder, and the importance of activated eosinophils found in central airway biopsies and in induced sputum is believed to be a hallmar
Bachs fötter och historien om orgelns identitet
Artikeln är en essäliknande diskussion om orgelns identitet och plats i västerländsk kulturhistoria utifrån David Yearsleys bok "Bach's Feet: The Organ Pedals in European Culture" (Cambridge UP, 2012). Fokus ligger på J.S. Bach, tysk kulturhistoria och historieskrivandets avgörande roll för att förstå nutida debatter om orgelinstrumentet.
Road traffic noise, air pollution and myocardial infarction: a prospective cohort study.
Both road traffic noise and air pollution have been linked to cardiovascular disease. However, there are few prospective epidemiological studies available where both road traffic noise and air pollution have been analyzed simultaneously. The aim of this study was to investigate the relation between road traffic noise, air pollution and incident myocardial infarction in both current (1-year average
