In osteoblasts, cyclooxygenase 2 (COX-2) is the major isozyme responsible for production of prostaglandins. Prostaglandins are local mediators of bone resorption and formation and are known to be involved in bone's adaptive response to fluid shear stress (FSS). We have previously described a model of trabecular bone loss in hindlimb-suspended mice and rats and demonstrated partial protection from
This questionnaire survey was initiated to acquire information for prepration of a series of field studies. The paper deals with questions that were related to the thermal responses of the feet and footwear performance. The questionnaire was sent to a harbour, a telecommunication company and a customs office. At the harbour most of the workers used footwear with warm lining during winter. Half of
Despite their success in different segments of the food industry, membranes are not well-established in the beet and cane sugar industry. A comprehensive overview on the potential applications of membranes in both the beet and cane sugar industry is given. The part on the beet sugar industry focuses on pulp press water recycling, pectin production from beet pulp, beet juice purification, demineral
Laminin-8 (alpha4beta1gamma1) is one of the major laminin isoforms expressed in vascular endothelial basement membranes. Here we show that deletion of laminin-8 in mice affects angiogenesis under pathological conditions. Murine tumor models used in laminin alpha4-deficient mice results in hyperneovascularization and significant promotion of tumor growth and metastasis. The higher tumor growth rate
Aims: This study explores the knowledge, attitudes and practices among Somali and Sudanese immigrants in Denmark with regard to HIV/AIDS and condom use. Material and methods: A 78-item questionnaire, divided into five thematic sections, was given to 192 purposively selected Sudanese and Somalis of both sexes, aged 18-49, who had lived in Denmark for one or more years. It was administered in Arabic
Popular Abstract in Swedish Syftet med min avhandling är att utforska vilken funktionell roll naturliga mördar T (NKT) -celler har, samt vilka gener som är viktiga för dessa celler. NKT-celler utgör en liten men specialiserad undergrupp av T-celler, och är mycket intressanta eftersom att de, trots att de tillhör det specifika immunförsvaret, även har receptorer och egenskaper som är starkt förknipThis thesis focuses on a small population of non-conventional T lymphocytes, called natural killer T (NKT) cells. NKT cells have many unique features; such as recognition of glycolipids presented by CD1d, expression of NK receptors and rapid production of large amounts of cytokines, such as IL-4 and IFN-gamma,?upon activation. This early and robust cytokine burst is believed to give NKT cells the
When Sephadex beads (0.45mg/kg b.w) are instilled intratracheally into rats, a granulomatous alveolitis with giant cell formation and fibrosis occurs. Moreover, the events in the alveolar region are paralleled by an eosinophil-dominated peribronchitis/bronchiolitis and perivasculitis. Bronchoalveolar lavage (BAL) shows a very distinct feature with an early pronounced neutrophil increase, followed
New methodologies based on supercritical fluid extraction (SFE) have been developed for the determination of fat-soluble vitamins in processed foods. The results obtained so far indicate that SFE is well suited to extraction of fat-soluble vitamins from food products, although validation work is required to establish accuracy and precision. The vitamins investigated were A, E and beta-carotene, an
En enkätundersökning har genomförts bland brandingenjörer i Sverige med syftet att få information om detektionstider samt reaktions- och beslutstider vid en utrymning av tre olika lokaltyper; varuhus, restaurang och danslokal/nattklubb. Reslutaten kan ligga till grund för fortsatta studier för att bestämma partialkoefficienter för dimensionering av de gångvägar som används vid utrymning. Den ger o
Policies for handling cases of penicillin-non-susceptible Streptococcus pneumoniae (PNSP) in day-care groups vary between different counties in Sweden. The aim of this study was to evaluate the epidemiological effect of excluding PNSP-carriers from children's day-care centres (DCC). We followed the incidence in 14 DCC groups with ongoing PNSP-spread, by repeated group screens until no further case
The function of the mature polymorphonuclear neutrophil is dependent on its granules, each with its characteristic content of proteins. The granule proteins are formed at different stages during maturation of neutrophils from myeloblasts to segmented cells. The regulation of granule protein expression is controlled by a number of transcription factors, many of which are also essential for commitme
Conidiation in A. cichorii Nattras is reversibly stimulated by near UV radiation (NUV .apprx. 313 nm) and inhibited by blue light (.apprx. 450 nm) and apparently is a mycochrome-mediated process. After induction with plane-polarized NUV, blue light polarized perpendicularly to the NUV was more effective in counteracting the induction than was blue light polarized parallel to the NUV. Both the blue
New basis sets of the atomic natural orbital (ANO) type have been developed for the main group and rare gas atoms. The ANO's have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive and negative ions, and the dimer at its equilibrium geometry. Scalar relativistic effects are included through the use of a Douglas-Kroll Hamiltonian. Multico
Background: The " Lister family complex," an extensive Swedish family with autosomal dominant Parkinson disease, was first described by Henry Mjones in 1949. On the basis of clinical, molecular, and genealogic findings on a Swedish and an American family branch, we provide genetic evidence that explains the parkinsonism in this extended pedigree. Methods: Clinical methods included a detailed neuro
This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. The framework is based on projective geometry, which is the natural language for describing the geometry of multiple views. The affine and Euclidean geometries are rega
Glyceryl monooleate (GMO) and other unsaturated long-chain monoglycerides show peculiar phase behaviour characterised by the presence of one or more cubic liquid-crystalline phases. In the present study, hydrolysis of cubic lipid-water phases formed by GMO were determined. Human pancreatic carboxyl ester lipase (CEL), colipase-dependent lipase with colipase, human duodenal contents and rat pancrea
