Trace element interactions can affect the absorption, metabolism, or effects of elements. Also, different elements may derive from the same source. Associations in biological media between element concentrations may indicate such phenomena. A large number of correlations were found between 13 trace elements (Co, Cu, Zn, Se, Rb, Rh, Pd, Cd, W, Pt, Hg, Tl, and Pb) in human blood and/or serum, as inv
DNA ploidy has been shown to be a predictive parameter for prognosis in various solid tumours. The prognostic value of DNA-ploidy in gastric cancers is still a matter of controversy. A possible explanation for the discrepant results reported in the literature could be sampling error in tumours with multiple stemlines differing in DNA-ploidy. In order to determine whether or not such heterogeneity
Synthesis of 1-glyceryl monooleyl ether (GME) has been accomplished yielding material of high purity (99.6%). The aqueous phase behavior of synthesized lipid has been investigated by using polarized microscopy and small angle X-ray diffraction. As a result, a partial temperature-composition phase diagram has been constructed. GME forms a reversed micellar solution and reversed hexagonal liquid cry
A biphasic injectable bone substitute, suitable for filling bone defects, that sets in the body, based on calcium sulfate and hydroxyapatite (HA), is presented. For applications in bone defects the compressive strength is important to assure support of the defect site during loading when the patient is weight bearing. To control the strength, the influence of four different factors; the liquid-to-
In an investigation by the Swedish Cancer Society, an expert group described the present status, critical issues and future aspects and potentials for each of nine major areas of radiation therapy research. The present report deals with therapy with radiopharmaceuticals.
Huvudtes: Hur kan det komma sig att de flesta företag inom besöksnäringen väljer att rekrytera internt? Frågeställning: Inom besöksnäringen är den externa rekryteringen av chefspositioner begränsad: - Varför föredrar företagen inom besöksnäringen att rekrytera internt? Syfte: Syftet med uppsatsen är att undersöka hur och i vilken utsträckning företag i besöksnäringen rekryterar. Vi vill även belys
Syfte: Syftet är att utveckla en modell för värdering av företag i konkurs och där avsikten är att driva företaget vidare efter genomförd konkurs. Metod: Vår uppsats grundar sig främst på empirin och kan därför sägas ha en induktiv ansats. Vi har använt oss av kvalitativa metoder där vi har intervjuat personer som har god kännedom om företagsvärdering samt nyckelpersoner hos två företag. Företagen
Olika forskare poängterar vikten av att ha en god riskkommunikation men däremot anser vi att mindre teori fokuserar på hur denna information ska kommuniceras. Efter följande antagande blir fokus i denna studie inte att betona vikten av att risk måste kommuniceras utan istället att analysera och diskutera hur den ska kommuniceras. Med denna utgångspunkt vill vi mer ingående undersöka hur de olika a
PURPOSE: To examine sex differences in health-related quality of life (HRQoL) among patients surgically treated for renal cell carcinoma (RCC) in Sweden, utilizing data from the National Swedish Kidney Cancer Register (NSKCR).METHODS: In this study of 4658 surgically treated RCC patients, data on HRQoL, clinical, demographic, and socioeconomic characteristics were retrieved from the NSKCR for pati
OBJECTIVE: To evaluate circumferential resection margin (CRM) as a risk factor for distant metastasis (DM) in rectal cancer.SUMMARY BACKGROUND DATA: The treatment of rectal cancer has evolved over the last decades. Surgical radicality is considered the most important factor in preventing recurrences including local and distant. CRM ≤1.0 mm is considered to increase recurrence risk. This study expl
Bone morphogenetic proteins (BMPs) are pleiotropic secreted proteins, structurally related to transforming growth factor (TGF)-beta and activins. BMPs play pivotal roles in the regulation of embryonic lung development and branching of airways and have recently been considered to influence inflammatory processes in adults due to their chemotactic activity on fibroblasts, myocytes, and inflammatory
Adverse and analgesic effects of acupuncture during the second and third trimesters of pregnancy were studied retrospectively in an observational study including 167 consecutive patients with lower back pain, pelvic pain, or both. In each patient acupuncture was given on at least two different occasions by three manual stimulations of two or more acupuncture or tender points, mainly LR-3 and LI-4
Biomagnification and polychlorinated biphenyl (PCB) congener distribution was examined in a predator-prey, host-parasite system, in which Atlantic salmon (Salmo salar) preyed upon sprat (Sprattus sprattus). Eubothrium crassum was an intestinal parasite in salmon that also "preyed upon" sprat, because the parasites gained access to foodstuffs via the host (salmon) gut. Salmon contained significantl
I mars 2019 röstade EU-parlamentet igenom Direktivet om upphovsrätt på den digitala inre marknaden (”DSM-direktivet”) som medför förändringar i ansvarsstrukturen för upphovsrättsliga intrång på nätet. Direktivets kanske mest kontroversiella artikel är art 17 som behandlar ansvar för särskilda internetplattformar, så kallade ”onlineleverantörer av delningstjänster för innehåll” (”onlineleverantörerIn March 2019, the European Parliament adopted the Directive on Copyright in the Digital Single Market ("the DSM Directive") which implies changes in the liability regime of online copyright infringements. Perhaps the most controversial article in the directive is Art 17, which regulates liability on specific internet platforms, so-called "online content-sharing service providers” (
Otoliths, or earstones, are small, biogenic concretions of aragonitic calcium carbonate precipitated on a protein matrix. Otoliths form part of the hearing and balance system in teleost fishes, and grow as the fish grow, providing a continuous biochronology of growth. Various elements are entrained in minor and trace quantities. In particular, strontium is a useful scalar of habitat use when varia
