Alterations of the fragile histidine triad gene, FHIT, and its encoded products contribute to testicular germ cell tumorigenesis

The fragile histidine triad (FHIT) gene, located within chromosome arm 3p, is a potential target for testicular tumorigenesis. In the present study, 62 primary testicular germ cell tumors were analyzed for allelic imbalance (AI) at 10 loci mapping to chromosome bands 3p14.1-21.1. Twenty-seven tumors (44%) showed AI at one or more 3p loci. The chromosome 3 copy number was evaluated by fluorescence

Propagation characteristics of polarized radio waves in cellular communications

Narrowband and wideband measurements of the radio channel using different combinations of transmit and receive polarization have been performed. The measurements cover a range of scenarios including urban, suburban and open terrain, as well as both outdoor and indoor terminals. The vertical-to-vertical (V-V) and horizontal-to-horizontal (H-H) polarization combinations are found to provide equal re

The Feynman-Wilson gas and the Lund model

We derive a partition function for the Lund fragmentation model and compare it with that of a classical gas. For a fixed rapidity “volume” this partition function corresponds to a multiplicity distribution which is very close to a binomial distribution. We compare our results with the multiplicity distributions obtained from the JETSET Monte Carlo for several scenarios. Firstly, for the fragmentat

Exposure, health effects, immunological markers and biomarkers of susceptibility among Swedish rubber workers

Popular Abstract in Swedish Arbetare i gummiindustrin utsätts för ett stort antal kemikalier med hög giftighet. Tidigare forskning har visat att kemikalierna innebär en fara för hälsan. Gummiarbetarna har tidigare haft en ökad risk att drabbas av olika sjukdomar, t.ex. cancer, hjärtkärlsjukdomar och luftvägsbesvär, jämfört med allmänbefolkningen. Däremot vet man inte exakt vilka ämnen som är farliWorkers in the rubber industry have an increased risk of several diseases, such as airway disease, cancer and probably cardiovascular disease. The exposure is very complex; carbon disulfide (CS2) and polycyclic aromatic hydrocarbons (PAHs) being two of the contaminants. The general aim of this thesis was to find exposure-response relationships usable for risk assessments in the rubber industry. U

Adolescent respiratory symptoms-girls are at risk: The Young-HUNT study, Norway

The objective was to study sex differences in adolescence regarding prevalence of asthma and current wheeze and to explore the association between respiratory symptoms and hereditary, lifestyle and socioeconomic factors. Young-HUNT included data comprehensive questionnaire on health, disease, lifestyle and social factors from 8817 teenagers 13-19 years conducted in 1995/97 (89% response rate). Que

In-field monitoring of cleaning efficiency in waste water treatment plants using two phenol-sensitive biosensors

Two amperometric biosensors based on the enzymes cellobiose dehydrogenase (CDH) and quinoprotein-dependent glucose dehydrogenase (GDH), have been applied for monitoring the phenolic content in water samples, collected at different stages of a waste water treatment process, thus representing different cleaning levels of two waste water treatment plants (WWTPs). The biosensor measurements were perfo

Quadricuspid aortic valve not discovered by transthoracic echocardiography.

Background Quadricuspid aortic valve is a rare congenital heart defect. Several different anatomical variations of a quadricuspid aortic valve has been described and aortic regurgitation is the predominant valvular dysfunction associated with quadricuspid aortic valve. Case presentation A 68-year-old woman presented with almost a years history of increasing dyspnoea on exertion. The patient have

Alkali metal emission from filter ash and fluidized bed material from PFB gasification of biomass

The alkali metal emission from materials collected in a PFB biomass gasification pilot plant has been characterized. Samples of SiC filter ash and fluidized bed particles from different operating conditions were subjected to a constant heating rate up to 1000 degrees C in a nitrogen atmosphere, and the alkali metal emission was monitored continuously by a surface ionization technique. For all samp

Silurian Carbonate Platforms of Gotland, Sweden - Archives of Local, Regional and Global Environmental Changes

Popular Abstract in Swedish Denna doktorsavhandling syftar till att identifiera och tolka förändringar i den marina miljön, avspeglade i Gotlands siluriska berggrund. Silurperioden (ca 444-416 miljoner år sedan) har traditionellt beskrivits som ett tidsintervall med ett varmt växthusklimat och hög global havsnivå med små miljömässiga förändringar i den marina miljön. Under det senaste decenniet haThis thesis treats the Silurian carbonate platforms of Gotland, Sweden, which formed close to the equator within the East Baltic Basin. Three different time intervals, all involving changes in facies composition and structure of the platforms, have been studied; Late Homerian, latest Homerian ? earliest Gorstian, and late Ludfordian, respectively. Two of the intervals, the Late Homerian and the la
