Anorexia nervosa in 51 Swedish adolescents: premorbid problems and comorbidity

Fifty-one teenage cases with anorexia nervosa (AN) were compared with 51 age-, sex-, and school-matched cases with respect to premorbid developmental, physical, and psychiatric problems and comorbidity at the time of examination. Almost half of the AN group consisted of the total population of AN cases in one birth cohort. There were more premorbid personality problems in the AN group. Obsessive c

Bacterial Terminal Oxidases. Studies in Bacillus subtilis

The final step in aerobic respiratory pathways is catalyzed by terminal oxidases. Bacteria generally have two or more terminal oxidases. Aerobically grown Bacillus subtilis synthesize three terminal oxidases: one cytochrome c oxidase, cytochrome caa3 and two quinol oxidases, cytochrome aa3 and cytochrome bd. In addition, a fourth cytochrome of bd-type has been predicted from the genome sequence. C

Studies on Haemproteins of Gram-positive Bacteria - Implications as Antibacterial Drug Targets

With the discovery of antibiotics, several diseases that were previously lethal is today readily cured, or so we thought. Some degree of resistance to one or several antibiotics can be found among many strains of clinical important bacteria. The problem has been somewhat kept at bay for the last few decades by altering already existing antibiotics, and thereby prolonging their usage. It is clear t

Current status of dosimetry at the boron neutron capture therapy facility at Studsvik, Sweden

The beam was successfully characterized in air and in phantom using various radiation dosimeter:,. The determination of the thermal neutron and photon components of the mixed beam in phantom can be determined with acceptable uncertainties, while the uncertainty of the high-energy neutron component is considerable but of limited clinical significance. The beam intensity is sufficiently high for rea

The mechanisms controlling heat and mass transfer on frying of beefburgers

The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied. The evolution of the char
