Studies of occlusal adjustment therapy in patients with craniomandibular disorders

In the first part of this thesis, measurement and registration procedures of occlusal interferences and their inter and intraobserver variability were evaluated. In the second part of this thesis, the short and long-term effect of occlusal adjustment therapy was prospectively assessed in a controlled clinical trial in a selected group of 50 patients with myogeneous craniomandibular disorders (CMD)

Home, Women and Children. Norms and Knowledge Acquisition in Social Services Home Visits in Post-war Sweden

This article deals with how Swedish welfare authorities, governmental as well as municipal, performed personal case studies during the period 1940 to 1970. The visits at home are focused, as a mean of the authorities to generate truth of the inquired woman. The home visit was part of a personal case inquiry, perhaps initiated from the authorities to create basic data for decision-making. The examp

How Does Control Timing Affect Performance?

The article presents two Matlab-based tools for analysis andsimulation of real-time control systems: Jitterbug andTrueTime.Jitterbug allows the user to compute aquadratic performance criterion for a linear control system undervarious timing conditions. The control system is described using anumber of continuous- and discrete-time linear systems. Astochastic timing model with random delays is used

Artificial carrier for oxygen supply in biological systems

Several poly (dimethylsiloxanes) (PDMS) copolymers of dimethylsiloxane (DMS) with ethylene or propylene oxide were tested as artificial carriers for the delivery of oxygen to biological systems. Copolymers with a DMS content of 33% or lower enhanced glucose oxidation by 200% in contrast to the 25% increase produced by the same concentration of perfluorodecalin. When 0.05% of the copolymer with 18%

Adsorption of MUC5B and the role of mucins in early salivary film formation

Salivary mucins are known to play important roles in the formation of oral salivary films. The aims of the present study were to investigate the behaviour of salivary mucins at solid surfaces with different wettabilities, as well as the influence of electrolyte on the adsorption behaviour. A pure preparation of human salivary MUC5B was used together with a commercial one of bovine submaxillary muc

Metabolic impact of a family history of Type 2 diabetes. Results from a European multicentre study (EGIR)

BACKGROUND: Insulin resistance was found in some but not in all previous studies of non-diabetic first degree relatives of Type 2 diabetic patients. Small study groups, ethnic differences and/or non-optimal techniques may explain the conflicting results. AIM: To study the impact of a family history of Type 2 diabetes on insulin action in a large group of non-diabetic Europeans using the 'gold stan

Medical proton dosimetry using radioluminescence from aluminium oxide crystals attached to optical-fiber cables

The prime objective of this study is to investigate if radioluminescence (RL) from carbon-doped aluminum oxide (Al2O3:C) crystals potentially can be used for absorbed dose-rate measurements during proton radiotherapy. The RL from two separate (2 mg) Al2O3:C crystals attached to optical-fiber cables were recorded during irradiations in water in a 175 MeV clinical proton beam. The RL response for lo

Lifetime fitness of short- and long-distance dispersing great reed warblers

Dispersal is of prime importance for many evolutionary processes and has been studied for decades. The reproductive consequences of dispersal have proven difficult to study, simply because it is difficult to keep track of dispersing individuals. In most previous studies evaluating the fitness effects of dispersal, immigrants at a study locality have been lumped into one category and compared to ph

Abundances of vanadium and bromine in 3 Centauri A - Additional odd-Z anomalies

We report abundance excesses of 1.2 and 2.6 dex, respectively, for vanadium and bromine in the hot, peculiar star 3 Cen A. Abundances for these two odd-Z elements have not been previously reported for this star. Taken with previous work, they strengthen the case of the origin of the abundance peculiarities by diffusion.

Adoption or infanticide: Options of replacement males in the European starling

The behaviour of a male bird towards a potential mate and her clutch may depend both on his expected paternity and on the likelihood that she will produce a replacement clutch if he commits infanticide. In this study we evaluate the choices made by replacement male European starlings Sturnus vulgaris. By removing males before and during laying, we induced other males, mainly neighbours, to mate wi

Reliability of gait performance tests in men and women with hemiparesis after stroke.

Objective: To assess the reliability of 6 gait performance tests in individuals with chronic mild to moderate post-stroke hemiparesis. Design: An intra-rater (between occasions) test-retest reliability study. Subjects: Fifty men and women (mean age 586.4 years) 6–46 months post-stroke. Methods: The Timed “Up & Go” test, the Comfortable and the Fast Gait Speed tests, the Stair Climbing ascend a

Effects of red meat and fiber in high fat diet on activities of sphingomyelinase, ceramidase and caspase-3 in rat colonic mucosa.

Red meat and fiber rich foods are the dietary factors most consistently related to colon carcinogenesis. Although several components in these dietary sources may contribute, the biochemical mechanism by which red meat and fiber affect colorectal carcinogenesis has not yet been established. Sphingomyelin metabolism is a novel signal transduction pathway that may have an impact on colonic tumorigene

Influence of heat treatment on lipid oxidation and glutathione peroxidase activity in chicken and duck meat

To study the role of glutathione peroxidase for lipid oxidation in meat, chicken and duck muscle were heated to an internal temperature of 60, 70 or 80 degrees C and the meats were then stored at 8 degrees C for up to 6 days. Thiobarbituric-acid-reactive substances (TBARS) and glutathione peroxidase (GSHPx) activity were measured on days 0, 1, 3 and 6. In heated muscle samples, TBARS increased dur

ON THE THEORY OF COINCIDENCE SPECTRA

We discuss spectra where both a primary photoelectron and a secondary decay particle are measured. We point out the striking similarity with threshold-excited emission spectra and predict resonant peaks analoguous to those found in resonant photoemission.
