Eukaryotic phytoplankton exhibit an enormous species richness, displaying a range of phylogenetic, morphological and physiological diversity. Yet, until recently, very little was known about the diversity, genetic variation and evolutionary processes within species and populations. An approach to explore this diversity and to understand evolution of phytoplankton is to use population genetics as a

Många kommuner i Sverige ställer krav på miljöbilar i upphandlingen av kommunala tjänstebilar, och en del ställer även specifika krav på elbilar. Detta projekt har utvärderat offentlig upphandling för att svara på frågor om vilken potential upphandling har för att främja förnybara drivmedel, vilka de praktiska erfarenheterna är, huruvida offentlig upphandling används strategiskt och hur styrmedlet

Summary-The role of stress in the development of disease has been the subject of considerable research in the last few years. Stressful life events have been related to many physical and psychological disorders. The DSM-IV devoted Axis IV to these kinds of events. There is, however, scant information on the possible mediating role of sex on perception of stressful life events, or on the validation

We examined the convergent validity of three posttraumatic symptoms inventories, the civilian version of the Mississippi Scale for Combat-Related PTSD (CM-PTSD), the Trauma Symptom Checklist-40 (TSC-40), and the Response to Childhood Incest Questionnaire (RCIQ), in a sample of 52 adult sexual abuse survivors. The significant and moderate to strong correlations (r = .6 or higher) among these invent

Objective: To develop and assess the efficacy of a multimodal balance-enhancing exercise program (BEEP) designed to be regularly self-administered by community-dwelling elderly. The program aims to promote sensory reweighting, facilitate motor control, improve gaze stabilization, and stimulate continuous improvement by being constantly challenging. Method: Forty participants aged 60 to 80 years pe

OBJECTIVE: Outcome after treatment of vestibular schwannomas can be evaluated by health providers as mortality, recurrence, performance, and morbidity. Because mortality and recurrence are rare events, evaluation has to focus on performance and morbidity. The latter has mostly been reported by health providers. In the present study, we validate 2 new scales for patient-assessed performance and mor

Vertigo is one of the most common complaints in medicine. Despite its high prevalence, patients with vertigo often receive either inappropriate or inadequate treatment. The most important reasons for this deplorable situation are insufficient interdisciplinary cooperation, nonexistent standards in diagnostics and therapy, the relatively rare translations of basic science findings to clinical appli

The aim of this study was to assess postural control, vestibular symmetry and health status in otherwise healthy hip fracture subjects and compare these factors with controls. The fracture subjects were recruited from 113 consecutive patients operated 12-33 months earlier. Nineteen of those were otherwise healthy and fulfilled the inclusion criteria. They were assessed and compared with 28 age- an

Thirty patients with Menière's disorder, 11 patients with cochlear hearing loss of other aetiologies and 10 normally-hearing subjects, were investigated using transtympanic electrocochleography (TT ECochG). Alternating polarity clicks, condensation and rarefaction clicks and long tone-bursts of 1 kHz were used for stimulation. The latencies of the AP responses to click stimulation were evaluated.

Although deaf children depend upon sight for communication, retinitis pigmentosa is present in 6 per cent of those with a profound hearing deficit. Usher syndrome type 1 (USH-1) is an autosomal recessive disease characterised by profound hearing impairment, absent vestibular function, and progressive loss of vision due to retinitis pigmentosa. Owing to the severe handicap of the combined disorders

To assess changes in postural control among healthy elderly and to correlate with suspected age-related events, 33 women and 16 men were studied. Postural control was evaluated by vibration-induced body sway, measured on a force platform, and vibration sensation was tested with a tuning fork. Occurrence of spontaneous gaze and head-shake-induced nystagmus was observed with infrared charged couple

An objective method for the pre-operative diagnosis and the post-operative assessment of a presumed perilymphatic fistula (PLF) using transtympanic electrocochleography is presented. Three cases are reported in which the history of the disease and the symptoms strongly suggested the presence of a PLF. Pre-operative transtympanic electrocochleography (TT ECoG) recordings at rest showed changes simi

Background: Ovarian cancer early detection markers CA125, CA15.3, HE4, and CA72.4 vary between healthy women, limiting their utility for screening. Methods: We evaluated cross-sectional relationships between lifestyle and reproductive factors and these markers among controls (n = 1910) from a nested case-control study in the European Prospective Investigation into Cancer and Nutrition (EPIC).
