Purpose: The purpose of this clinical investigation was to evaluate the treatment outcome with zygoma implants with regard to implant survival, patient satisfaction, and function of prosthesis replacement after 3 years. Patients and Methods: The treatment outcome of 76 patients treated with 145 zygoma fixtures at 16 centers was evaluated with regard to implant survival. Status of peri-implant muco

Previously we observed that neural cell adhesion molecule (NCAM) deficiency in P tumor cells facilitates metastasis into distant organs and local lymph nodes. Here, we show that NCAM-deficient P cell tumors grew leaky blood vessels with perturbed pericyte-endothelial cell-cell interactions and deficient perivascular deposition of ECM components. Conversely, tumor cell expression of NCAM in a fibro

The topic of this thesis is the study of finite volume methods for hyperbolic conservation laws on non-uniform meshes. A high-order hyperbolic reconstruction method is presented. The method is constructed for quadrilateral meshes, since more realistic hyperbolic problems involve more complicated problem domains than the standard rectangular ones. The method is an extension of the well known

We found that the Black grouse (Tetrao tetrix) possess low numbers of Mhc class II B (BLB) and Y (YLB) genes with variable diversity and expression. We have therefore shown, for the first time, that another bird species (in this case, a wild lek-breeding galliform) shares several features of the simple Mhc of the domestic chicken (Gallus gallus). The Black grouse BLB genes showed the same level of

The incidence of post-transfusion hepatitis non-A, non-B (PTH-NANB) was prospectively assessed in two areas in the southeast region of Sweden. Patients undergoing hip arthroplasty were studied with blood sampling for alanine aminotransferase analysis before and at 2, 3, and 4 months after transfusion. Of the patients 97% and 82% were transfused and received a mean of 5.5 and 3.4 units in Linkoping

Classical conditioning of motor responses, e.g., the eyeblink response, depends on the cerebellum. In the theoretical works of David Marr (1969) and James Albus (1971), it was proposed that Purkinje cells in the cerebellar cortex learn to associate the neutral conditioned stimulus with the response. Since their work, several studies have provided data that are consistent with this suggestion, but

Background. The systemic and local tissue repair responses of radiation in combination with surgery are still unclear. We have studied the effect of fractionated pre-operative radiotherapy with or without subsequent laparotomy on collagen accumulation using a rodent model. Materials and methods. Thirty-two male Sprague-Dawley rats were divided into four groups (eight rats per group): 1) sham radia

The effect of postharvest long-term storage and pre-treatments on the mass transfer rates during osmotic dehydration of carrots was investigated. Four blanching times were used and the carrots were sampled during 12 weeks of storage. Cell vitality was measured by isothermal calorimetry on cores taken from blanched slices. During the storage period, effective diffusion coefficients for water and su

Sixteen young patients with type 1 diabetes mellitus and rapidly progressive severe retinopathy were examined regarding serum levels of growth hormone before and after the i.v. administration of 200 micrograms thyrotropin-releasing hormone (TRH). Serum IGF I, HbA1c, blood pressure, urinary albumin, and serum creatinine levels were also measured. The control group consisted of type 1 diabetic patie

This study investigates the mechanisms of (de)coding modality, focusing on the interpretation of utterances containing the modals must, may, måste, and kan. The main research question posed in this study is what enables the interlocutors to interpret modal expressions so that communicative goals are achieved. To answer this general question, Coates's (1983) study on modal contexts is initially rep

Immune responses constitute a major way for hosts to defend themselves against parasites. Because hosts do not habitually produce strong responses all the time, immune responses might be costly to produce or maintain. We tested experimentally if the production of a response to a challenge with a novel antigen resulted in a cost in terms of fitness using the highly colonial house martin Delichon ur

Does psychology approach personality from the wrong direction? The present text argues that conventional personality psychology, spproaching its object of study from "above", i.e., mapping out the individual´s consciously held attitudes and view of him-/herself, has chosen the wrong path to a tenable science of personality. The alternative would be to scrutinize the processes by which the perceive

Graphite electrode modified with laccase from Cerrena unicolor served as a biosensor for detection of 30 phenolic compounds with different structures. Some correlations of the sensor response to the structures of substrates are discussed. This biosensor responded to: (i) nanomolar concentrations of some of the selected phenolic compounds, e.g., 2,6-dimethoxyphenol,coniferyl alcohol, caffeic acid,

A woman presented at 28 wk gestation with fetal bradycardia 50 bpm, which persisted until 42 wk when an asymptomatic male baby was delivered. Electrocardiograph at 3 wk of age documented an incessant atrial fibrillation with slow ventricular response. He continued to be asymptomatic, but on follow-up at 16 y of age, 24-h Holter monitor showed a heart rate of 23 bpm and pauses of up to 6 s when a V

The aim of this study was to investigate a new extracorporeal immunoadsorption method to improve tumor-to-normal tissue ratios in radioimmunoimaging (RII) and radioimmunotherapy (RIT). We have developed and investigated a general method using biotinylated antibodies and an agarose-avidin column for extracorporeal immunoadsorption. The studies were made in an animal model and extracorporeal immunoa

One frequently used classification of flow cytometric DNA ploidy status (diploid versus nondiploid) was compared with a division into seven ploidy classes based on DNA index (DI) and number of cell populations (hypodiploid, diploid, near-hyperdiploid, hyperdiploid, tetraploid, hypertetraploid, and multiploid). The latter ploidy classification showed a better correlation with prognosis and other pr

Novel experimental results on mirror nuclei in the sd and fp shells are presented. Their respective Mirror Energy Difference (MED) diagrams are interpreted by means of large-scale shell-model calculations. A unique way of extracting effective charges from isospin symmetry studies is also discussed.

This is the fourth Research Seminar on Self-Desiccation in Concrete organized by the Building Materials Division of Lund University. The three previous seminars were held in 1997, 1999, and 2002.
