Purpose: Several tumor markers have recently been applied for prostate cancer screening. We analyze the effectiveness of prostate specific antigen (PSA), age specific PSA, PSA velocity, volume adjusted PSA densities, change in PSA level following antibacterial therapy, free-to-total PSA ratio, alpha1-antichymotrypsin bound PSA, alpha2-macroglobulin bound PSA, alpha1-protease inhibitor bound PSA an

Autoignition in SI engines is an abnormal combustion mode and may lead to engine knock which is an undesired phenomenon in SI engines. It may cause damage and it is a source of noise in engines. Knock limits the compression ratio of the engine and a low compression ratio means low fuel conversion efficiency of the engine. This thesis presents a theoretical investigation about the modeling of the e

Two methods for the determination of hexahydrophthalic anhydride (HHPA) in air were developed. In a solid sorbent method, HHPA was sampled in Amberlite XAD-2 tubes, eluted in toluene and analysed by gas chromatography with flame ionization detection. The sampling rates were 0.2 and 1.0 l/min. At 15 micrograms/m3 (relative humidity less than 2%) and 27 micrograms/m3 (relative humidity 70%) no break

The European Directives on personal protective devices have increased the interest in protective and functional properties of work clothing and intensified standardisation work as well as stimulated research in areas with limited knowledge. There is a long tradition of research and information exchange in the Nordic countries on the subject. The NOrdisk KOrdineringsgruppe om BEskyttelseskläder som

Post-sternotomy mediastinitis is a serious complication after cardiothoracic surgery and contribute significantly to post-operative morbidity, mortality, and healthcare costs. Negative pressure wound therapy is today's golden standard for post-sternotomy mediastinitis treatment. A systematic literature search was conducted at PubMed until October 2012 to analyse whether vacuum-assisted closure tec

CdTe semiconductor nanocrystals were synthesized with three different stabilizers: Mercaptoacetic Acid (MM), Mercaptopropionic Acid (MPA) and 2-Mercaptoethanol (ME) at pH approximate to 11.2 by wet chemical route using potassium tellurite and cadmium chloride as starting materials. The effect of capping agent on the preparation of these samples was evaluated using UV-Visible absorption and photolu

The alleged efficacy of pharmaceutical industry self-regulation has been used to repudiate increased government oversight over promotional activity. European politicians and industry have cited Sweden as an excellent example of self-regulation based on an ethical code. This paper considers antidepressant advertising in Sweden to uncover the strengths and weaknesses of self-regulation.

Prophylaxis and treatment with antiretroviral drugs, a consequent low viral load, and the use of elective Caesarean section, are factors that radically decrease the risk of HIV transmission from mother to child during pregnancy and delivery. The availability of new antiretroviral drugs, updated general treatment guidelines and increasing knowledge of the importance of drug resistance, have necessi

There is an increasing interest in achieving gene regulation in biotechnological and biomedical applications by using synthetic DNA-binding agents. Most studies have so far focused on synthetic sequence-specific DNA-binding agents. Such approaches are relatively complicated and cost intensive and their level of sophistication is not always required, in particular for biotechnological application.

A key to the lichen family Parmeliaceae in the Alps is presented. Notes on their distribution and phylogeny are added. The family is represented in the Alps by 41 genera and c. 147 species.

Background: Distal radius fracture is a common injury and may result in substantial dysfunction and pain. The purpose was to investigate the relationship between distal radius fracture malunion and arm-related disability. Methods: The prospective population-based cohort study included 143 consecutive patients above 18 years with an acute distal radius fracture treated with closed reduction and eit
