Long-term lithium treatment is associated with end-stage renal disease, but there is little evidence of a clinically significant reduction in renal function in most patients. We previously found that 1.5% of people who took lithium from the 1960s and 1970s developed end-stage renal disease; however, none of the patients who started after 1980 had end-stage renal disease. Here we aimed to study the
BACKGROUND: An increasing number of young patients are undergoing knee arthroplasties. Thus, the long-term risks of having a knee prosthesis must be evaluated. This study focuses on the potential carcinogenic effects of the prosthesis; it is a long-term follow-up of all patients in Sweden between 1975 and 2006. METHODS: The incidence of cancer in a total population of operated individuals was comp
As a lecturer in mathematics for first-year university students one faces several challenging problems; big classes, low motivation and a high level of abstraction. Based on interviews with several experienced university lecturers in mathematics, we present a toolbox of tips and tricks intended to be used when reflecting over one's own teaching in order to improve it.

Designs for Extremely Large Telescopes (ELTs) are quite well advanced,but the requirements of instruments have had limited impact. Sinceprovision of a suitable environment for instruments is a critical aspectof all telescopes, we outline some well-known and some less-appreciatedchallenges of designing instruments for ELTs. A wide-field spectrometer(WFSPEC) with ~10 arcmin field-of-view, probably w
In this paper the feasibility of using a fully integrated 65nm CMOS PA in future machine-type communication standards has been investigated. The integrated PA investigated shows a linear output power in VSWR 2:1 of minimum 24dBm. A VSWR of 2:1 with an associated 3.1dB front-end insertion loss corresponds to a VSWR of 5:1 at the antenna, which is a conservative number. The PAE at 1dB compression po

Impaired glucose metabolism and diabetes mellitus has been linked to a decreased risk for abdominal aortic aneurysm development in men. We evaluated potential relationships between blood glucose levels in 1722 men with mean age 34 years and their aortic diameter measured by ultrasound at age 65 years.
