Using the combined Golgi-electron microscopy technique, we have determined the three-dimensional dendritic fields of the short visual fibres (svf 1-3) and first-order interneurons or L-fibres (L1-4) within the first optic ganglion (lamina) of the nocturnal bee Megalopta genalis. Serial cross sections have revealed that the svf type 2 branches into one adjacent neural unit (cartridge) in layer A, t
Objective: To analyse the extent to which traumatic life events, post-traumatic stress disorder (PTSD) and the neuropsychiatric disorder attention deficit hyperactivity disorder (ADHD) can be contributors associated with burnout and the long-term sick leave that results from it. Subjects: Sixty-two individuals on long-term sick leave due to stress-related poor health and burnout, and 83 working in
It has been generally accepted that increasing aerosols suppress precipitation. The aerosol-induced precipitation suppression was suggested by the study of shallow stratiform clouds. Recent studies of convective clouds showed increasing aerosols could increase precipitation. Those studies showed that intense feedbacks between aerosols and cloud dynamics led to increased precipitation in some cases
Dysthymia and major depressive disorder (MDD) are both risk diagnoses for suicidal behaviour. The aim of the present study was to identify clinical differences between these disorders, with a special reference to dysthymia. We studied suicidal behaviour, comorbidity and psychiatric symptoms of inpatient suicide attempters with dysthymia and MDD. We used DSM III-R diagnostics, the Suicide Assessmen
Nematode-trapping fungi enter the parasitic stage by developing specific morphological structures called traps. The global patterns of gene expression in traps and mycelium of the fungus Monacrosporium haptotylum were compared. The trap of this fungus is a unicellular spherical structure called the knob, which develops on the apex of a hyphal branch. RNA was isolated from knobs and mycelium and hy
The evidence concerning the possible association between physical activity and the risk of prostate cancer is inconsistent and additional data are needed. We examined the association between risk of prostate cancer and physical activity at work and in leisure time in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. In our study, including 127,923 men aged 20-97 years
The clinical diagnosis Of Multiple system atrophy (MSA) is fraught with difficulty and there are no pathognomonic features to discriminate the parkinsonian variant (MSA-P) from Parkinson's disease (PD). Besides the poor response to levodopa, and the additional presence of pyramidal or cerebellar signs (ataxia) or autonomic failure as major diagnostic criteria, certain other clinical features known
The LKB1 tumour suppressor kinase phosphorylates and activates a number of protein kinases belonging to the AMP-activated protein kinase (AMPK) subfamily. We have used a modified tandem affinity purification strategy to identify proteins that interact with AMPKalpha, as well as the twelve AMPK-related kinases that are activated by LKB1. The AMPKbeta and AMPKgamma regulatory subunits were associate
Numerous lineages of avian malaria parasites of the genus Plasmodium have been deposited in GenBank. However, only 11 morphospecies of Plasmodium have been linked to these lineages. Such linking is important because it provides opportunities to combine the existing knowledge of traditional parasitology with novel genetic information of these parasites obtained by molecular techniques. This study l
Six methyl cellulose (MC) samples, one with a IDS Of 1.32 and five with a DS between 1.83 and 1.88, were degraded with five different enzymes or enzyme preparations containing endoglucanases. The main goal was to investigate whether enzymes could be used for determination of heterogeneity of the substituent distribution along the cellulose chain. To obtain information about the heterogeneity it wa
Neuronal apoptosis was observed in the rat dentate gyrus in two experimental models of human limbic epilepsy. Five hours after one hippocampal kindling stimulation, a marked increase of in situ terminal deoxynucleotidyltransferase-mediated dUTP nick-end labeling (TUNEL) of fragmented DNA was observed in nuclei located within and on the hilar border of the granule cell layer and in the polymorphic
Background Oral contraceptives were introduced almost 50 years ago, and over 100 million women currently use them. Oral contraceptives can reduce the risk of ovarian cancer, but the eventual public-health effects of this reduction will depend on how long the protection lasts after use ceases. We aimed to assess these effects. Methods Individual data for 23 257 women with ovarian cancer (cases) a
We present progress in the development of artificial photosynthesis, as a means to harvesting and storage of solar energy. The plan is to compose molecular systems that combine known photochemistry with emerging functional model compounds. A photochemical device for solar energy conversion contains a photosensitizer, an electron acceptor system and a donor system that prevents charge recombination
Popular Abstract in Swedish I denna avhandling diskuteras förbättringar inom skallskadevården både vad gäller akut behandling och rehabilitering. Bakgrund Svåra traumatiska hjärnskador är en av de vanligaste orsakerna till död eller bestående invaliditet i västvärlden. Trafikskador dominerar, men fall (i samma plan eller från hög höjd), misshandel samt skottskador förekommer även. De två senare Mortality after severe head injury can be considerably reduce with a therapy using physiological principles for brain volume regulation and preserved microcirculation, with the main purpose of restricting the rise in ICP to reasonable levels simultaneously with preservation of adequate blood supply. This study shows that the ?Lund Concept? can reduce mortality in patients with severe traumatic bra
Popular Abstract in Swedish För några år sedan uppmärksammades att ungdomars sexuella vanor hade förändrats. Ett nytt begrepp gjorde sig gällande i det offentliga samtalet: analsex. Oavsett hur förändringen av ungdomars sexuella vanor förklarades betraktades analsex med få undantag som ett oacceptabelt, onormalt och onaturligt beteende. I beskrivningarna av analsex formulerades inte enbart vad somThis dissertation deals with the drawing of boundaries between normal and abnormal, between natural and unnatural. The aim is to show how the conditions for intimacy and hence also intimacy between women have changed in modern society, how sex and sexuality have been perceived, organized, and experienced in relation to historical and cultural circumstances. The study proceeds from two collections
Popular Abstract in Swedish Alla människor har säkert någon gång i sitt liv haft en vanlig förkylning med snuva, och ökad slemproduktion som främsta symtom. På luftvägsslemhinnans yta möter kroppen omvärlden i form av inhalerade partiklar, bakterier och virus som fastnar i den tunna slemfilm som normalt täcker och skyddar det yttersta cellagret. Vid irritation av slemhinnan ses ofta en förhöjd sleMucins are essential components of the mucosal barrier. The complexity of the airway mucosal barrier is reflected in the lack of specific treatments to block mucin hypersecretion associated with several respiratory diseases such as chronic bronchitis, asthma and cystic fibrosis. Currently, researchers in the mucin field are confronted with a growing number of mucin genes. In order to understand th
