Introduction: Evidence for the current guidelines for the treatment of patients with chronic total occlusions (CTO) in coronary arteries is limited. In this study we identified all CTO patients registered in the Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and studied the prevalence, patient characteristics and treatment decisions for CTO in Sweden. Methods and Results: Between Ja
Erysipelas is a common infection that often recurs, but the impact of specific risk factors for reoccurrence remains elusive. In the present study we aimed at clarifying predisposing conditions for reoccurrence.
Mitochondria are the main site for energy conversion in the cell. Under certain circumstances, such as excess calcium retention or production of reactive oxygen species, a pore forms at contact sites between the outer and the normally impermeable inner mitochondrial membrane. The ensuing osmotic mitochondrial swelling and loss of bioenergetic function is referred to as the mitochondrial permeabili
We have investigated the scaling properties of [111] InAs nanowire MOSFETs in the ballistic limit. The nanowire band structure has been calculated with an Sp(3)d(5)s* tight-binding model for nanowire diameters between 2 and 25 nm. Both the effective band gap and the effective masses increase with confinement. Using the atomistic dispersion relations, the ballistic currents and corresponding capaci
Hypo-fractionated external beam radiotherapy with narrow CTV-PTV margins is increasingly applied for prostate cancer. This demands a precise target definition and knowledge on target location and extension during treatment. It is unclear how increase in fraction size affects changes in prostate volume during treatment. Our aim was to study prostate volume changes during extreme hypo-fractionation
Sperm performance is likely to be an important determinant of male reproductive success, especially when females copulate with multiple males. Understanding sperm performance is therefore crucial to fully understand the evolution of male reproductive strategies. In this study, we examined the repeatability of sperm morphology and motility measures over three breeding seasons, and we studied relati
We present a detailed comparison of ectopic ossification (EO) found in tendons of biglycan (Bgn), fibromodulin (Fmod) single and double Bgn/Fmod-deficient (DKO) mice with aging. At 3 months, Fmod KO, Bgn KO and DKO displayed torn cruciate ligaments and EO in their quadriceps tendon, menisci and cruciate and patellar ligaments. The phenotype was the least severe in the Fmod KO, intermediate in the
Vid genomgång av anmälningar till Socialstyrelsen avseende missad fraktur i halsryggen noteras flera återkommande brister vid både den kliniska bedömningen och den radiologiska utredningen samt att flertalet av dessa allvarliga vårdskador hade kunnat undvikas.
Key stereoelectronic properties of Desulfovibrio desulfuricans [FeFe]-hydrogenase (DdH) were investigated by quantum mechanical description of its complete inorganic core, which includes a Fe6S6 active site (the H-cluster), as well as two ancillary Fe4S4 assemblies (the F and F' clusters). The partially oxidized, active-ready form of DdH is able to efficiently bind dihydrogen, thus starting H-2 ox
Popular Abstract in Swedish Teamarbete är en populär arbetsform inom hälso- och sjukvården och teamarbete anses kunna göra sjukvården både effektivare och säkrare. Detta gäller inte minst för arbete med kirurgi på operationssal. På operationssalen möts narkosläkare, narkossjuksköterskor, kirurger, operationssjuksköterskor och undersköterskor i olika konstellationer för att tillsammans behandla patThe topic of this thesis is teamwork in healthcare. Healthcare is often described as complex. This description is more appropriate now than ever with the extensive specialization that has taken place in recent decades resulting in increasingly specialized physicians and nurses. While this specialization has made it possible to cure even sicker patients, it has also resulted in less overlapping kno
In previous studies on Supplemental Instruction (SI) relatively little attention has been paid to the “senior” students who lead the sessions. The focus in this study is on the benefits that the SI leaders gain from their SI experience. Data from one questionnaire directed at 35 students who recently completed their assignment as SI leaders, and another questionnaire directed at 20 former SI leade
In light of heightened interest in the response of pollen phenology to temperature, we investigated recent changes to the onset of Betula (birch) pollen seasons in central and southern England, including a test of predicted advancement of the Betula pollen season for London. We calculated onset of birch pollen seasons using daily airborne pollen data obtained at London, Plymouth and Worcester, det
In addition to HPV, high parity and hormonal contraceptives have been associated with cervical cancer (CC). However, most of the evidence comes from retrospective case-control studies. The aim of this study is to prospectively evaluate associations between hormonal factors and risk of developing cervical intraepithelial neoplasia grade 3 (CIN3)/carcinoma in situ (CIS) and invasive cervical cancer
