Background: Propionibacterium acnes is a commensal of human skin but is also known to be involved in certain diseases, such as acne vulgaris and infections of orthopaedic implants. Treatment of these conditions is complicated by increased resistance to antibiotics and/or biofilm formation of P. acnes bacteria. P. acnes can be infected by bacteriophages, but until recently little has been known abo
Cultured Schwann cells in tendon autografts for nerve repair improve the early phase of nerve regeneration in rat sciatic nerves as judged by the rate of axonal outgrowth. We tested the long-term effects on functional recovery using measurements of muscle force, the number of axons and myelination, using morphometry. In addition, we recorded wet weight of the gastrocnemius muscle. Schwann cell cul
A recent study reported a large increase in the number of meniscal procedures from 2000 to 2011 in Denmark. We examined the nation-wide distribution of meniscal procedures performed in the private and public sector in Denmark since different incentives may be present and the use of these procedures may differ from region to region.
We exploit a series of robust, but simple and convenient colloidal lithography (CL) approaches, using a microsphere array as a mask or as a guiding template, and combine this with surface-initiated atom-transfer radical polymerization (SI-ATRP) to fabricate patterned polymer-brush microstructures. The advantages of the CL technique over other lithographic approaches for the fabrication of patterne
The authors argue that Information Security Management (ISM) would benefit from studies that examine the social and psychological mechanisms that, when in evidence, generate employee aware¬ness of information security (IS) related issues. Properly instilled, IS awareness has the power to en¬gender a proactive wariness beyond mechanical guidelines, however detailed. To study how awareness travels i
Genome-wide association (GWA) studies have identified multiple loci at which common variants modestly but reproducibly influence risk of type 2 diabetes (T2D)(1-11). Established associations to common and rare variants explain only a small proportion of the heritability of T2D. As previously published analyses had limited power to identify variants with modest effects, we carried out meta-analysis
Objectives To describe the ultrasound characteristics of endometriomas in pre- and postmenopausal patients and to develop rules that characterize endometriomas. Methods All patients included in the International Ovarian Tumor Analysis (IOTA) studies were used in our analysis. Patients with an adnexal mass were scanned by experienced sonologists using a standardized research protocol. The gold stan
Hematopoiesis, the formation of blood cells, ultimately depends on a rare population of hematopoietic stem cells (HSCs), which can both self-renew to maintain the HSC pool, and differentiate into all mature blood lineages. HSC fate decisions are governed by a complex combination of numerous signals, although the molecular mechanisms are not fully understood. This thesis describes the role of two i
Previous studies have shown that endothelin type B (ETB) and 5-hydroxytryptamine type IB (5-HTIB) receptors are upregulated following subarachnoid hemorrhage (SAH). The purpose of the present study was to test whether extracellular signal-regulated kinase (ERKI/2) inhibition could alter the degree of SAH induced receptor upregulation in addition to prevent the cerebral blood flow (CBF) reduction.
Injection into the two MAX IV storage rings will not make use of a 4-kicker local injection bump. Instead, pulsed multipole injection will be used for initial filling as well as top-up injection. Since commissioning a pulsed multipole magnet for injection into a storage ring is non-trivial, it has been decided to install a single dipole kicker magnet into the storage rings to provide a simple meth
The large international variation in the incidence of prostate cancer (PC) is well known but the underlying reasons are not understood. We want to compare PC incidence and survival among immigrants to Sweden in order to explain the international differences. Cancer data were obtained from the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for PC in first-degree immig
Plasmodium falciparum infected red blood cells (iRBC) express variant surface antigens (VSA) of which VAR2CSA is involved in placental sequestration and causes pregnancy-associated malaria (PAM). Primigravidae are most susceptible to PAM whereas antibodies associated with protection are often present at higher levels in multigravid women. However, HIV co-infection with malaria has been shown to al
Yacon (Smallanthus sonchifolius (Poepp. and Endl.) H. Robinson) is a storage root originally grown in the Andean highlands. The fresh roots are perishable and quickly turn brown during handling and processing. Aiming to prolong shelf-life and to preserve the antioxidant compounds in yacon roots, 3 mm thick yacon slices were dried in a drying cabinet at 40, 50, and 60 degrees C to a moisture conten
This paper studies the influence of metropolitan externalities on productivity for different types of long-run R&D engagement based on information from the Community Innovation Survey. We apply a dynamic general method of moments model to a panel of manufacturing and service firms with different locations in Sweden, classified as a metropolitan region, the largest metropolitan region, a metrop
Unannounced evacuation experiments in a cinema theatre were analysed. The analysis focused on investigating if people are influenced by others during the initial phase of a fire evacuation. This type of influence is called social influence. Three separate behaviour types were identified and studied and the recognition and pre-movement time was measured. The results suggest that social influence is
Huntington's disease (HD), a fatal neurodegenerative disorder, is associated with an increased risk of diabetes mellitus. The reason for this is unknown, but considering the functional similarities of neurons and the insulin secreting pancreatic β-cell, pathological mechanisms may be shared by both cell types and account for neuronal as well as endocrine dysfunction. Hence, finding the mechanisms
We demonstrate how CasADi, a recently devel- oped, free, open-source, general purpose software tool for nonlinear optimization, can be used for dynamic optimization in a flexible, interactive and numerically efficient way. CasADi is best described as a minimalistic computer al- gebra system (CAS) implementing automatic differentiation (AD) in eight different flavors. Similar to algebraic modeling
Efforts are made in radiographic examinations to obtain the best image quality with the lowest possible absorbed dose to the patient. In dental radiography, the absorbed dose to patients is very low, but exposures are relatively frequent. It has been suggested that frequent low-dose exposures can pose a risk for development of future cancer. It has previously been reported that there was no signif
