Abstract
The endogenous glycosphingolipid sulfatide is a ligand for CD1d-restricted type II natural killer T (NKT) lymphocytes. Through the action of these cells,sulfatide treatment has been shown to modulate the immune response in mouse models for autoimmune diseases, infections and tumour immunity. Sulfatide exists naturally in different organs including the pancreas, where sulfatide colocalizes with insulin within the Langerhans islet b-cells, targets for the immune destruction in type 1 diabetes (T1D). Human T1D patients, but not patients with type 2 diabetes nor healthy individuals, have autoantibodies against sulfatide in serum, suggesting that sulfatide induces an immune response in the natural course of T1D in humans. Here, we investigate sulfatide as an autoantigen and a modulator of autoimmune disease in the murine model forT1D, the non-obese diabetic (NOD) mice. We demonstrate that aged NOD mice displayed serum autoantibody reactivity to sulfatide; however, this reactivity did not correlate with onset of T1D. Repeated administration of sulfatide did not result in an increase in serum reactivity to sulfatide. Moreover, a multidose sulfatide treatment of female NOD mice initiated at an early (5 weeks of age),intermediate (8 weeks of age) or late (12 weeks of age) phase of T1D progression did not influence the incidence of disease. Thus, we demonstrate that a fraction of NOD mice develop autoantibody reactivity to sulfatide; however, we fail to demonstrate that sulfatide treatment reduces the incidence of T1D in this mouse strain.

Abstract
BACKGROUND Alzheimer's disease (AD) is a neurodegenerative disorder where β-amyloid tends to aggregate and form plaques. Lipid raft-associated ganglioside GM1 has been suggested to facilitate β-amyloid aggregation; furthermore, GM1 and GM2 are increased in lipid rafts isolated from cerebral cortex of AD cases. AIM/METHOD The distribution of GM1 and GM2 was studied by immunohistochemistry in the frontal and temporal cortex of AD cases. Frontotemporal dementia (FTD) was included as a contrast group. RESULTS The distribution of GM1 and GM2 changes during the process of AD (n = 5) and FTD (n = 3) compared to controls (n = 5). Altered location of the GM1-positive small circular structures seems to be associated with myelin degradation. In the grey matter, the staining of GM1-positive plasma membranes might reflect neuronal loss in the AD/FTD tissue. The GM1-positive compact bundles were only visible in cells located in the AD frontal grey matter, possibly reflecting raft formation of GM1 and thus a pathological connection. Furthermore, our results suggest GM2 to be enriched within vesicles of pyramidal neurons of the AD/FTD brain. CONCLUSION Our study supports the biochemical finding of ganglioside accumulation in cellular membranes of AD patients and shows a redistribution of these molecules.

Abstract
OBJECTIVES Patients with multiple sclerosis were reported to harbour antibodies not only against proteins and glycoproteins but also against glycolipids, including sulfatide and galactosylceramide (GalCer), the two major glycosphingolipids of myelin. However, previous results were inconsistent concerning glycosphingolipid levels, antibody type, dominance of serum or Cerebrospinal fluid compartments and relationship to the multiple sclerosis (MS) course. RESULTS We hereby report that the cerebrospinal fluid levels of sulfatide were increased in patients with MS (n = 46) compared with controls (n = 50, P < 0.001). In addition, patients had higher serum IgM anti-glycosphingolipid titres than controls (P = 0.03 for sulfatide, <0.001 for GalCer), while the anti-glycosphingolipid IgM antibodies in the cerebrospinal fluid were essentially normal. However, in seven of 46 patients cerebrospinal fluid IgG antibodies against GalCer (P = 0.004) could be detected, which was not found in any of the control individuals, and this finding might mirror the occurrence of more specific B-cell clones behind the blood-brain barrier. CONCLUSIONS The IgM immunoreactivity in serum did not show any relationship to the type of course or severity of MS, arguing against a phenomenon secondary to myelin damage. Thus, the IgM antibody findings are compatible with an early antigen challenge or autoimmunity associated with natural antibodies.

Abstract
This study of perceptual and motor skills in soccer players was conducted on adolescent males. The goals were to monitor the development of general perceptual motor skills in nonsoccer-playing and soccer-playing groups ( n = 245), to examine the relationship between physical maturity and general perceptual motor skills ( n = 41), and to compare the differences in general perceptual motor skills between groups with different soccer expertise ( n = 142). The measured variables were simple reaction time, peripheral awareness, eye–hand–foot coordination, and testosterone blood level. The results suggested that general perceptual motor skills improved with age, the development of these skills was related to participants' blood testosterone concentration (especially between 12 and 14 years), and general perceptual motor skills improved with soccer expertise. However, the differences between subelite and elite soccer players were not meaningful enough to encourage practitioners to test general perceptual motor skills on a large scale when evaluating the potential of young players.

Abstract
OBJECTIVE To assess and compare the consequences for outcome in terms of the dimensions of activity and participation for two groups: group A, which received early formalized rehabilitation, and group B, which received late or no formalized rehabilitation. RESEARCH DESIGN A cross-sectional study. PROCEDURE Twenty-six patients (A: n = 14 and B: n = 12) with severe brain damage were included. The participants were assessed a mean of 26.6 months (SD 7.1, median 25, range 14-41) after the incident using the structured form for the Swedish Neuro database, the Glasgow Outcome Scale (GOS), the Extended Glasgow Outcome Scale (GOSE) and the Functional Independence Measure (FIM). RESULTS The study reveals a better outcome for group A. No patient remained in a vegetative state in group A as compared with three in group B. In group A, 50% were independent as compared with 17% in group B. The frequency of return to work was 43% in group A, but no patient in group B had returned to work.

Involvement of sulfatide in beta cells and type 1 and type 2 diabetes. Diabetologia 2005; 48:1957-62.

Abstract
Mammalian tissues express beta-isoforms of glycosphingolipids and, among these, sulfatide (sulphated galactosylceramide) is present in the beta cells, and it is here that the short fatty acid chain (C16) isoform is predominately found. In vitro studies have shown that sulfatide preserves insulin crystals and facilitates insulin monomerisation under certain biochemical conditions. It also activates beta cell potassium channels and moderates insulin secretion. Anti-sulfatide antibodies are seen in type 1 diabetes, and immunological presentation of glycosphingolipids by the non-classical CD1 molecules has recently been reported. It is via this mechanism that alpha-galactosylceramide and sulfatide are able to influence the innate immune system and inhibit autoimmunity, possibly through regulatory natural killer T cells. Administration of sulfatide substantially reduces the incidence of diabetes in non-obese diabetic mice and prevents antigen-induced experimental autoimmune encephalomyelitis in wild-type mice. Sulfatide has specific anti-inflammatory properties, increasing the number of CD3+CD25+ regulatory T cells and reducing production of several cytokines, including TNF-alpha. Patients with type 2 diabetes have low serum concentrations of sulfatide, and some animal models of type 2 diabetes have low pancreatic expression of C16:0 sulfatide; administration of this increases insulin secretion and improves first-phase insulin response in Zucker fatty rats. Glycosphingolipids in general, and sulfatide in particular, appear relevant to both type 1 and type 2 diabetes.

Abstract
AIMS The glycosphingolipid sulfatide (sulfated galactosyl-ceramide) increases exocytosis of beta-cell secretory granules, activates K(ATP)-channels and is thereby able to influence insulin secretion through its presence in the islets. A closely related compound, sulfated lactosylceramide (sulf-lac-cer), is present in the islets during fetal and neonatal life when, as in Type 2 diabetes, insulin is secreted autonomically without the usual first phase response to glucose. The aim was to examine whether serum concentrations of these glycolipids are associated with Type 2 diabetes. METHODS A case-control study, comprising 286 women and 283 men, was designed using a population-based sample of patients with Type 2 diabetes and a population survey. RESULTS Low serum concentrations of sulfatide were associated with Type 2 diabetes, independent of traditional risk factors for diabetes in a sex-specific analysis: odds ratio (OR) 2.1 (95% confidence interval 1.1, 3.9) in men, and 2.3 (1.2, 4.3) in women, comparing the lowest and the highest tertiles. Type 2 diabetes was also associated with detectable amounts of sulf-lac-cer in serum: OR 1.7 (0.9, 3.4) in men, and 7.6 (3.8, 15.2) in women. After adjustment for confounding from other diabetes risk factors, these associations remained basically unchanged. The connections between sulfatide and Type 2 diabetes, and sulf-lac-cer and Type 2 diabetes were independent of each other. Insulin resistance (HOMA-IR) was negatively correlated with sulfatide concentration and positively correlated with sulf-lac-cer (both P < 0.0001, independently). CONCLUSIONS We report a new, robust and highly significant independent association between Type 2 diabetes and serum concentrations of sulfatide in both sexes, and sulf-lac-cer in females. The associations were also independent of other known diabetes risk factors.

Abstract
In this work we show that supersonic cluster beam deposition is a viable method for the synthesis of nanocrystalline metal/carbon composites. By assembling carbon and metallic clusters seeded in a supersonic beam, we have grown films consisting of metal nanoparticles embedded in a nano-structured carbon matrix. Samples containing 3d transition metals (Ti, Ni) and noble metals (Au, Pd, Pt) with different metal abundances, particle size and dilution have been characterized by transmission electron microscopy. The influence of different metals on the structure of the carbon matrix has been investigated. Spatially resolved ultraviolet photoemission electron spectroscopy showed substantial surface oxidation of 3d transition metal clusters. On a micrometric scale, the spatial distribution of the metallic nanoparticles appeared to be homogeneous.

Abstract
Rotavirus, the most common cause of childhood gastroenteritis, has been implicated as one of the viral triggers of diabetes-associated autoimmunity. To study the possible association between rotavirus infections and the development of diabetes-associated autoantibodies, we measured the prevalence of rotavirus antibodies in serum samples collected at 3-6-month intervals up to the age of 2 years from 177 children selected from consecutive newborns because they carried HLA-DQB1 alleles associated with increased risk for type 1 diabetes. Twenty-nine of the children developed at least two of four diabetes-associated autoantibodies (ICA, IAA, GADA or IA-2A) during the first 2 years of life (the cases), whereas 148 children remained autoantibody-negative matched with the cases for date of birth, gender, living region and HLA-DQB1 alleles. The temporal association between the development of the first-appearing diabetes-associated autoantibody and rotavirus infections was studied by analysing whether the cases had a diagnostic increase in rotavirus antibody titre more often during the 6-month period that preceded seroconversion to autoantibody positivity than the controls. By the age of 12 months one of the 13 case children (7%), who had a serum sample drawn at that age and who had developed at least one type of diabetes-associated autoantibodies, had experienced a rotavirus infection, while 12 of the 61 (20%) autoantibody-negative control children had had a rotavirus infection. By 18 months, four of the 22 autoantibody-positive cases (18%) and 18 of the 89 controls (20%) had rotavirus antibodies, and by the age of 24 months the respective numbers were five of the 27 cases (19%) and 32 of the 113 (28%) controls. A rotavirus infection occurred during the 6 months preceding the sample which was positive for an autoantibody in four of the 25 periods (16%) for which both necessary samples were available, while the controls had a rotavirus infection during 55 of the 370-such periods (15%). Accordingly, our data suggest that rotavirus infections are unlikely triggers of beta-cell autoimmunity in young children with genetic susceptibility to type 1 diabetes.

Abstract
The cell nucleus plays an essential role in all aspects of cell function and regulation. Most of the nuclear proteins/peptides are synthesized in the cytoplasm and transported into the nucleus through the nuclear pore complexes. The nuclear proteins/peptides conjugate with each other and interact in transcriptional activation/inactivation. Several of the high molecular mass transcription factors (> 30 kDa) have been identified and characterized. However, the information on the low molecular mass proteins/peptides of the nucleus is limited. We have investigated these low molecular mass proteins/peptides from the nucleus of human peripheral blood lymphocytes using reversed-phase high-performance liquid chromatography (RP-HPLC). The HPLC fractions were further analysed by matrix assisted laser desorption/ionization time of flight (MALDI-TOF) mass spectrometry, electrospray ionization time of flight (ESI-TOF) mass spectrometry and electrospray ionization fourier transform ion cyclotron resonance (ESI-FTICR) mass spectrometry for mass determination. Using this combination of mass spectrometry techniques and microsequence analysis, we have shown that human lymphocyte nuclei contain defensins, a mixture of human neutrophil granule peptide 1, 2 and 3.

Abstract
We studied 24 bruxers (23-67 years old). They often complained of orofacial and bodily pain and presented autonomic symptoms (sweating 23%, palpitations at night 62%, decreased libido 50%); 19% had increased blood pressure requiring treatment, and 65% reported frequent headaches in the morning. Deep sleep and rapid eye movement (REM) were delayed. An average of 167 orofacial episodes developed during the night. The mean number of masseter bursts strictly defined as bruxism was 79, the mean delay for the first occurrence after sleep onset 18 minutes. The majority of bruxism occurred in stage 2 sleep and REM sleep. The mean number of shifts of sleep stages was 70, one-third occurring within the first minute following a bruxing episode, and 15% of bruxing episodes developed after a shift in sleep stage. Electroencephalogram showed alpha-delta pattern in 15% of the subjects. Short-lasting alpha activity was often encountered during the 10 seconds preceding the development of a bruxing episode. Tachycardia developed at its onset, persisting for 10 seconds. We suggest that, as a minor alarm response to endogenous/exogenous stimuli, arousal develops and is often followed by motor activation, such as a burst of bruxing, with, as in any situation when motor activity suddenly increases, a secondary increase of heart activity.

Abstract
A controlled release (CR) formulation of remoxipride (Roxiam(®), Astra) given once-daily was compared to immediate release (IR) remoxipride given twice-daily, with respect to efficacy and tolerability, in a 4-week multicentre parallel-group dose titration (200-600 mg/day) study with acutely ill schizophrenic patients. Forty- three patients received remoxipride CR (mean dose 344 mg/day) and 49 patients received remoxipride IR (mean dose 346 mg/day). Efficacy was assessed using the Kolakowska version of the Brief Psychiatric Rating Scale (BPRS score of ≥ 18 points at entry) and the Clinical Global Impression scale (CGI), while extrapyramidal symptoms were rated using the Simpson and Angus scale. Both formulations of remoxipride produced clinical improvement, with the BPRS median total score falling from 35 at baseline to 16 at last rating in the remoxipride CR group, and from 33 to 12.5 in the remoxipride IR group. More than 70% of the patients in both groups were assessed as 'much improved' or 'very much improved' according to the CGI scale. Both formulations of remoxipride were well-tolerated, with a low incidence of treatment-emergent adverse symptoms, including extrapyramidal side effects. No statistically significant differences were detected between the treatment groups with regard to efficacy, safety or tolerability.

Abstract
Sixty-two DSM III chronic schizophrenic inpatients were selected for a double-blind, placebo controlled, multi-centre, relapse prevention study of remoxipride, a selective dopamine (D2)-receptor antagonist. After a 1 month placebo washout, 23 patients had relapsed and were withdrawn. Of the remaining patients 19 were randomised to remoxipride (150-300 mg daily) and 20 to placebo. Their median age was 58 years, 26 were male, and the median duration of illness was 33 years. After 24 weeks a further total of 8 remoxipride and 17 placebo patients had been withdrawn. Excluding three patients withdrawn for reasons other than relapse, the comparative relapse rates were 37% and 75%, respectively (P = 0.015). Efficacy analyses using clinical global impression (P = 0.04) and change in BPRS scores (P = 0.016) were in favour of remoxipride. Extrapyramidal symptoms were minimal in both groups. Treatment emergent adverse events were similar in the two groups. Remoxipride is therefore of potential value as a safe drug which is both effective and well tolerated in the long term management of chronic schizophrenic patients.

Abstract
Single dose pharmacokinetics and the antipsychotic effect of 4 weeks treatment with three fixed dose levels of remoxipride (a selective D(2) receptor antagonist) were studied in chronic, stable schizophrenic inpatients. After a placebo washout of 1 month, 15 patients entered the study. Of these, 11 patients received a single 50 mg oral dose of remoxipride for pharmacokinetic evaluations. All 15 patients were randomly assigned to treatment with oral remoxipride either 25 mg t.i.d., 50 mg t.i.d. or 100 mg t.i.d. for 4 weeks. Blood samples for remoxipride and prolactin assays were taken at 0, 0.33, 0.5, 0.66, 1.0, 1.5, 2, 3, 4, 8, 12, 24, 28, 32 and 48 h after drug intake. The pharmacokinetic characteristics were similar to those previously found in normal healthy volunteers: the mean peak plasma concentration of remoxipride after 50 mg was 3.3 μmol/l, the mean time to reach this was 2.1 h; the mean area under the plasma concentration/time curve was 27.8 μmol/1.h.1( -1) and the mean elimination half-life of remoxipride was 5.5 h. A significant increase in prolactin levels was detected 2 h after administration of remoxipride but they had reverted to normal 8 h after drug intake in all but one patient. Antipsychotic effects were estimated using the brief psychiatric rating scale (BPRS) and the Krawiecka rating scale (KRS) at admission, baseline (end of the 4 week placebo washout period) and after 7, 14 and 28 days treatment. Following an increase in mean psychosis ratings for both positive and negative symptoms during the placebo washout period, these decreased during active treatment and at the end of the study were similar to the scores on admission. Thus the possible efficacy of remoxipride in chronic patients with negative symptoms should be further explored in placebo controlled studies. Remoxipride was well tolerated. Sleep disorders occurred in three patients, extrapyramidal symptoms were not aggravated and no clinically significant effects were observed on the cardiovascular system, in clinical chemistry or haematology.

Abstract
In 16 controlled, randomized, comparative studies a total of 953 patients were treated for urinary tract infection, sinusitis, otitis media or chronic bronchitis. The aim was to evaluate the efficacy and safety of bacampicillin in a twice daily dosage, compared with three times daily dosages of bacampicillin, ampicillin, amoxycillin and a twice daily dosage of co-trimoxazole. Bacampicillin was given in amounts of either 400 or 800 mg to 422 of the patients in these studies. The twice daily dosage of bacampicillin eradicated 89% of the causative bacteria of urinary tract infections compared to 86% with the other regimens. In acute sinusitis 92% and 96% of the patients were either cured or improved when treated with 400 and 800 mg bacampicillin twice daily respectively. Similar percentages occurred in the groups given the three times daily dosages. In exacerbation of chronic bronchitis, 800 mg bacampicillin twice daily was the minimum effective dosage and 84% of the patients were either cured or improved with this regimen. Adverse drug reactions due to bacampicillin at all dose levels were less frequent than those of other anti-microbials. The lowest frequency of diarrhoea, 2.4%, was seen in the group given 400 mg bacampicillin twice daily. Dosages of 400 or 800 mg bacampicillin twice daily had a reliable efficacy combined with a low frequency of adverse reactions in respiratory and urinary tract infections.
