Total knee replacement in severe osteoarthritis usually requires extensive soft tissue releases often associated with considerable bleeding. In a prospective, randomised trial we compared postoperative conventional suction drainage versus four hour clamping drainage in 60 patients undergoing total knee arthroplasty for severe osteoarthritis. We compared blood loss, number of transfusions, postoper
Rising atmospheric carbon dioxide (CO2) may alleviate the toxicological impacts of concurrently rising tropospheric ozone (O-3) during the present century if higher CO2 is accompanied by lower stomatal conductance (g,), as assumed by many models. We investigated how elevated concentrations of CO2 and O-3, alone and in combination, affected the accumulated stomatal flux of O-3 (AFst) by canopies an
Systemic and local inflammation in relation to the resident microbiota of the human gastro-intestinal (GI) tract and administration of probiotics are the main themes of the present review. The dominating taxa of the human GI tract and their potential for aggravating or suppressing inflammation are described. The review focuses on human trials with probiotics and does not include in vitro studies a
Den 18:e nordiska kongressen arrangerad av Nordic Stroke Society ägde rum i Malmö den 26-28 augusti, 2015. Föreningen som i många år arrangerat nordiska strokekongresser bildades för över 30 år sedan. Denna rapport från årets kongress av Ann-Cathrin Jönsson, docent vid Institutionen för hälsovetenskaper, Lunds universitet, inleds med en beskrivning av bakgrunden till Nordic Stroke Society.
Hitherto unobserved long-lived massive particles with electric and/or colour charge are predicted by a range of theories which extend the Standard Model. In this Letter a search is performed at the ATLAS experiment for slow-moving charged particles produced in proton-proton collisions at 7 TeV centre-of-mass energy at the LHC, using a data-set corresponding to an integrated luminosity of 34 pb(-1)
Background: Cerebral ischemia activates both the innate and the adaptive immune response, the latter being activated within days after the stroke onset and triggered by the recognition of foreign antigens. Methods: In this study we have investigated the phenotype of antigen presenting cells and the levels of associated major histocompatibility complex class II (MHC II) molecules in the postischemi
Cervical cancer is the third most common cancer in women worldwide and the fourth leading cause of cancer death. In Western countries, it is the 10th most common cause of cancer death. Cervical cancer often affects young women (< 40 years) who have not finished childbearing. Robot assistance is the latest development in laparoscopic surgery. There is one robot commercially available for gynecologi
To investigate whether children with Attention Deficit/Hyperactivity Disorder have lower levels of Vitamin D3 at birth than matched controls.
Background: Evidence for an association of alcohol consumption with prognosis after a diagnosis of breast cancer has been inconsistent. We have reviewed and summarized the published evidence and evaluated the association using individual patient data from multiple case cohorts. Methods: A MEDLINE search to identify studies published up to January 2013 was performed. We combined published estimates
Scattering of electromagnetic waves by discrete, randomly distributed objects is addressed. In general, the non-intersecting scattering objects can be of arbitrary form, material and shape. The main aim of this paper is to calculate the coherent reflection and transmission characteristics of a slab containing discrete, randomly distributed scatterers. The integral representation of the solution of
Secondary hole-nesting birds that do not construct nest holes themselves and hence regularly breed in nest boxes constitute important model systems for field studies in many biological disciplines with hundreds of scientists and amateurs involved. Those research groups are spread over wide geographic areas that experience considerable variation in environmental conditions, and researchers provide
While rural House Sparrows (Passer domesticus) have declined in Sweden, the population of the related Tree Sparrow (P. montanus) has remained stable, suggesting that they are affected by different population regulating mechanisms. Here we investigated if the two species differ in degree of nest-site limitation. After conducting an initial survey of both species on farmsteads in southern Sweden, we
Given that not every city can be an alpha city in today's global urban hierarchy, what options do beta cities such as Toronto or Chicago realistically have in the cultural economy? Put differently, if cultural capitals such as New York, London, Paris, and Tokyo play critically important roles in certifying and establishing new trends in theatre, fashion, and other cultural industries, how can beta
Fe-Mn-O magnetic nanocrystals precipitate in a glass system SiO2/Na2O/Fe2O3/MnO during thermal annealing for different periods of time. We report here small angle neutron scattering investigations using polarized neutrons (pSANS) on these glass samples. Analysis of scattering data reveals the formation of spherical core-shell particles. The core of the particle is found to be magnetic and it is su
Background: The sporulation of aerial hyphae of Streptomyces coelicolor is a complex developmental process. Only a limited number of the genes involved in this intriguing morphological differentiation programme are known, including some key regulatory genes. The aim of this study was to expand our knowledge of the gene repertoire involved in S. coelicolor sporulation. Results: We report a DNA micr
A fused coarse-grained model of aromatic ionic liquids 1-alkyl-3-methylimidazoliums tetrafluoroborate ([CnMIM(+)][BF4(-)]) has been constructed. Structural and dynamical properties calculated from our model are compared with experimental data as well as with corresponding results from simulations of other suggested models. Specifically, we adopt a fused-sphere coarse-grained model for cations and
To increase the accuracy of molecular force fields a systematical and balanced improvement of the various terms included is needed. In this work, we have followed this strategy to improve the quality of the NEMO potential for the formaldehyde dimer by introducing local quadrupole moments and higher-order polarizabilities. It is found that inclusion of the quadrupole moment significantly improves t
