3D-macroporous chitosan-based scaffolds (cryogels) were produced via growth of metal-polymer coordinated complexes and electrostatic interactions between oppositely charged groups of chitosan and metal ions under subzero temperatures. A mechanism of reduction of noble metal complexes inside the cryogel walls by glutaraldehyde is proposed, which produces discrete and dispersed noble metal nanoparti
Background: Detailed, comprehensive, and timely reporting on population health by underlying causes of disability and premature death is crucial to understanding and responding to complex patterns of disease and injury burden over time and across age groups, sexes, and locations. The availability of disease burden estimates can promote evidence-based interventions that enable public health researc
INTRODUCTION: Autoantibodies against insulin (IAA) are early appearing markers of autoimmunity against the pancreatic islet beta cells and predict progression to type 1 diabetes if additional islet autoantibodies also develop. It is still controversial if proinsulin rather than insulin is the primary autoantibody.METHODS: The aim of the present study was to compare the half-maximal concentration (
We have examined concurrent and prospective validity of an index of self-reported walking (RW) of 307 home-dwelling women aged 75 years and above, of whom 155 in 1 year had in all 308 falls of which 13% resulting in fractures. It consists of five items concerning various aspects of self-reported walking identified by factor analysis. The sum score on this ''RW-index'' correlated moderately ( r = 0
Background. The objective was to determine how postmenopausal bleeding (PMB) is managed in Sweden today, and to relate the findings to a new evidence-based algorithm for the management of PMB. Methods. A questionnaire regarding the role of ultrasound and the use of different endometrial biopsy methods in the management of PMB was sent to all 61 gynecologic departments in Sweden. Results. Fifty-n
Popular Abstract in Swedish Kärnan kan ses som en samling nukleoner vilka hålls samman av den starka kraften. Nukleonerna är protoner (p) med laddning +1 och neutroner (n) med laddning 0. Kraften kan beskrivas som ett utbyte av mesoner såsom pioner (pi) vilka förekommer i tre laddningstillstånd pi+, pi- och pi0 (laddning +1, -1 och 0). Inuti kärnan rör sig nukleonerna och utbytesmesonerna vilket gA comprehensive near-threshold 4He(g,n) absolute cross section measurement has been performed at the high-resolution tagged-photon facility MAX-lab located in Lund, Sweden. The 20 < Eg < 45 MeV tagged photons (covering the Giant Dipole Resonance energy region) were directed towards a liquid 4He target, and knocked-out neutrons were detected in a pair of 60 cm x 60 cm vetoed NE213A liquid scintilla
In this study, a rapid and sensitive ultra-high performance supercritical fluid chromatography-mass spectrometry (UHPSFC-MS) method has been developed and partially validated for the separation of carotenoids within less than 6 min. Six columns of orthogonal selectivity were examined, and the best separation was obtained by using a 1-aminoanthracene (1-AA) column. The length of polyene chain as we
För var dag som går blir vårt samhälle allt mer beroende av teknik och snabb och lättillgänglig information. De flesta av oss söker dagligen efter någon sorts information på internet. Vi gör sökningar på allt som är av intresse för oss för stunden och allt fler inköp görs numera på nätet. Med denna nya, teknikberoende livsstil har det blivit allt viktigare för företag att marknadsföra sina varor oFor each day that passes our society becomes more and more dependent on technology and a fast and easy access to information. Most of us are using internet on a daily basis in search of information. We search for information regarding most things in our lives, from health, lifestyle and food to information regarding travel and work-related issues.

En wollastonitförekomst vid Stor Hulta gruvor i närheten av Nora har undersökts. I den nedlagda gruvan har tidigare skarnjärnmalm tillhörande leptitformationen brutits. I jämförande syfte har även wollastonit från Akatjvare i Tjåmotisområdet undersökts. Detta är LKAB:s prospekteringsobjekt och är beläget i Jokkmokks kommun. Resultaten för detta material, som utgörs av fyra stuffer av dubbel knytnäThe wollastonite occurrence at Hulta is a skarn deposit associated with iron ore within the Leptite Formation of central Sweden. Wollastonite is found in carbonate layers within the leptite and the rocks have been subject to regional metamorphism. These layers are normally approximately 10 cm thick. Corelogging, microscopic studies and X-ray diffraction show a varied composition of the rock, with
A multicentre study was performed at four oncology centres in Sweden, in 160 chemotherapy-naive women, primarily with ovarian or endometrial carcinomas. Abdominal surgery preceded chemotherapy in 146 (91%) women, and another 39 (24%) women had a history of radiotherapy. The chemotherapy regimens contained cisplatin (50-100 mg/m2), in combination with a variety of other agents. In Course 1, all pat
Second primary cancers (SPCs) are becoming a common cancer entity, which may interfere with survival in relatively benign first primary cancers. We examined the hypothesis that immune dysfunction may contribute to SPCs by assessing SPCs associated with known immune responsive skin cancers, invasive and in situ squamous cell carcinoma, Kaposi sarcoma, and Merkel cell carcinoma. Cancers were identif
BACKGROUND AND OBJECTIVES: Kidd blood group system consists of two major antigens: Jka and Jkb . Both the antigens are absent in individuals typed as Jknull and may develop clinically significant anti-Jk3 antibody. Screening donors for provision of Jknull blood is an ongoing task for blood centres with Jknull blood units kept frozen for specific requirements. In 2016, we discovered a previously ty
Environmental exposures to a myriad of chemicals are associated with adverse health effects in humans, while good nutrition is associated with improved health. Single chemical in vivo and in vitro studies demonstrate causal links between the chemicals and outcomes, but such studies do not represent human exposure to environmental mixtures. One way of summarizing the effect of the joint action of c
BACKGROUND: The aim of this study was to investigate the possibility of using extended-wavelength diffuse reflectance spectroscopy (EW-DRS) to measure tissue response related to blood perfusion. The study was performed on a model that we have previously found to be useful for studying techniques for perfusion monitoring following the injection of epinephrine in a local anesthetic in the human fore
In contrast to the peripheral role of mother tongue as a subject in Sweden, English has retained an elevated position. Together with Swedish, English is characterized as being crucial to Swedish society, positioning both languages at the top of the linguistic hierarchy. Given the generally perceived low status of mother tongue instruction (MTI) and high status of English in Sweden, an interesting
On October 28, 2021, Mark Zuckerberg announced the rebranding of Facebook to Meta through a keynote video uploaded on Meta’s official YouTube channel. The keynote video contains Meta’s new vision to build an immersive extended reality world called metaverse. However, the idea of the metaverse is contested. Meta’s metaverse has also been a hot debate in Indonesia for several months after Meta’s reb
Background Hexavalent chromium (Cr(VI)) is a carcinogen. Exposure to Cr(VI) may occur in different industrial processes such as chrome plating and stainless steel welding. The aim of this study was to assess occupational exposure to Cr(VI) in Denmark. Methods This cross-sectional study included 28 workers and 8 apprentices with potential Cr(VI) exposure and 24 within company controls, all recruite
Aim: There is ongoing controversy regarding the extent to which Hartmann's procedure (HP) should be used in rectal cancer treatment. This study was designed to investigate 30-day postoperative morbidity and mortality following HP, anterior resection (AR) and abdominoperineal resection (APR) for rectal cancer using a national registry. Methods: All patients operated for rectal cancer, tumour height
