Abstract
Herpes simplex virus type 1 (HSV-1) is a lifelong pathogen characterized by asymptomatic latent infection in the trigeminal ganglia (TG), with periodic outbreaks of cold sores caused by virus reactivation in the TG and subsequent replication in the oral mucosa. While antiviral therapies can provide relief from cold sores, they are unable to eliminate HSV-1. We provide experimental results that highlight non-thermal plasma (NTP) as a new alternative therapy for HSV-1 infection that would resolve cold sores faster and reduce the establishment of latent infection in the TG. Additionally, this study is the first to explore the use of NTP as a therapy that can both treat and prevent human viral infections. The antiviral effect of NTP was investigated using an in vitro model of HSV-1 epithelial infection that involved the application of NTP from two separate devices to cell-free HSV-1, HSV-1-infected cells, and uninfected cells. It was found that NTP reduced the infectivity of cell-free HSV-1, reduced viral replication in HSV-1-infected cells, and diminished the susceptibility of uninfected cells to HSV-1 infection. This triad of antiviral mechanisms of action suggests the potential of NTP as a therapeutic agent effective against HSV-1 infection.

Abstract
Alcohol's impairment of both hepatic lipid metabolism and insulin resistance (IR) are key drivers of alcoholic steatosis, the initial stage of alcoholic liver disease (ALD). Pharmacologic reduction of lipotoxic ceramide prevents alcoholic steatosis and glucose intolerance in mice, but potential off-target effects limit its strategic utility. Here, we employed a hepatic-specific acid ceramidase (ASAH) overexpression model to reduce hepatic ceramides in a Lieber-DeCarli model of experimental alcoholic steatosis. We examined effects of alcohol on hepatic lipid metabolism, body composition, energy homeostasis, and insulin sensitivity as measured by hyperinsulinemic-euglycemic clamp. Our results demonstrate that hepatic ceramide reduction ameliorates the effects of alcohol on hepatic lipid droplet (LD) accumulation by promoting VLDL secretion and lipophagy, the latter of which involves ceramide cross-talk between the lysosomal and LD compartments. We additionally demonstrate that hepatic ceramide reduction prevents alcohol's inhibition of hepatic insulin signaling. These effects on the liver are associated with a reduction in oxidative stress markers and are relevant to humans, as we observe peri- LD ASAH expression in human ALD. Together, our results suggest a potential role for hepatic ceramide inhibition in preventing ALD.

Abstract
Lipid droplets (LDs) are bioactive organelles found within the cytosol of the most eukaryotic and some prokaryotic cells. LDs are composed of neutral lipids encased by a monolayer of phospholipids and proteins. Hepatic LD lipids, such as ceramides, and proteins are implicated in several diseases that cause hepatic steatosis. Although previous methods have been established for LD isolation, they require a time-consuming preparation of reagents and are not designed for the isolation of multiple subcellular compartments. We sought to establish a new protocol to enable the isolation of LDs, endoplasmic reticulum (ER), and lysosomes from a single mouse liver. Further, all reagents used in the protocol presented here are commercially available and require minimal reagent preparation without sacrificing LD purity. Here we present data comparing this new protocol to a standard sucrose gradient protocol, demonstrating comparable purity, morphology, and yield. Additionally, we can isolate ER and lysosomes using the same sample, providing detailed insight into the formation and intracellular flux of lipids and their associated proteins.

Abstract
AIMS The aim of this study was to identify early foci of α-synuclein (α-syn pathology) accumulation, subsequent progression and neurodegeneration in multiple system atrophy of the cerebellar type (MSA-C). METHODS We analysed 70-μm-thick sections of 10 cases with MSA-C and 24 normal controls. RESULTS MSA-C cases with the lowest burden of pathology showed α-syn glial cytoplasmic inclusions (GCIs) in the cerebellum as well as in medullary and pontine cerebellar projections. Cerebellar pathology was highly selective and severely involved subcortical white matter, whereas deep white matter and granular layer were only mildly affected and the molecular layer was spared. Loss of Purkinje cells increased with disease duration and was associated with neuronal and axonal abnormalities. Neocortex, basal ganglia and spinal cord became consecutively involved with the increasing burden of α-syn pathology, followed by hippocampus, amygdala, and, finally, the visual cortex. GCIs were associated with myelinated axons, and the severity of GCIs correlated with demyelination. CONCLUSIONS Our findings indicate that cerebellar subcortical white matter and cerebellar brainstem projections are likely the earliest foci of α-syn pathology in MSA-C, followed by involvement of more widespread regions of the central nervous system and neurodegeneration with disease progression.

Abstract
Clinically isolated syndrome (CIS) represents the earliest phase of multiple sclerosis (MS). This study tested whether biomarkers for axonal degeneration can improve upon sensitivity and specificity of magnetic resonance imaging (MRI) parameters in predicting conversion from CIS to MS. Patients with CIS ( n=52), relapsing-remitting MS (RRMS, n=38) and age-matched controls ( n=25) were included. Cerebrospinal fluid (CSF) levels of tau and neurofilaments (NfHSMI35) were measured using ELISA. The MRI T2-lesion load and the Expanded Disability Status Scale (EDSS) were recorded. CSF tau and NfHSMI35 were elevated in CIS compared to controls (p<0.05). RRMS patients with acute relapse had higher NfHSMI35 levels than stable patients. Tau and NfHSMI35 levels correlated with EDSS in CIS and RRMS. In RRMS, the number of T2-lesions correlated with tau levels ( R=0.53, P=0.01). The sensitivity predicting the conversion from CIS to MS was higher for the combination of CSF markers (either tau or NfHSMI35 elevated) than for MRI (40 versus 34%), but could be further increased to 60% if CSF and MRI criteria were combined. Similarly, the combination of tau and NfHSMI35 showed higher specificity (94%) than MRI (82%). Tau and NfHSMI35 are valuable biomarkers for axonal damage in the CIS patients. Predicting conversion from CIS to MS can be improved if CSF markers are combined with MRI.

Abstract
Axonal damage has been proposed as the major substrate of permanent clinical disability in multiple sclerosis. Tau protein, a microtubule-associated protein localised in neuronal axons, may serve as a biochemical surrogate marker to evaluate axonal damage in vivo.We intended to determine the extent of axonal damage in different stages and clinical subtypes of MS by investigating cerebrospinal fluid tau concentrations. Tau was measured using an immunoassay in 35 patients with relapsing—remitting MS, eight patients with secondary progressive MS, nine patients with primary progressive MS, 50 patients with clinically isolated syndrome suggestive of early MS and 46 normal controls. Cerebrospinal fluid tau was significantly elevated in MS compared with normal controls (median 206.0 pg/mL versus152.0 pg/mL;P=0.002). No significant difference among different subtypes of MS could be detected, although highest levels were found in very early disease stages. There was a significant elevation of CSF tau among patients with gadolinium-enhancing brain lesions in magnetic resonance imaging (P=0.02) and a tendency towards higher CSF tau levels in patients with pronounced intrathecal IgG synthesis, supporting the notion that axonal damage is influenced by inflammatory activity.

Abstract
Amyotrophic lateral sclerosis is a devastating disease characterized by rapidly progressive paresis. The neuropathological hallmark of most amyotrophic lateral sclerosis cases are neuronal and glial aggregates of phosphorylated 43-kDa TAR DNA-binding protein (pTDP-43). The accumulation of similar proteins into insoluble aggregates is now recognized as a common pathological hallmark of neurodegenerative diseases in general. Importantly, many of these proteins such as tau and amyloid-β in Alzheimer's disease and α-synuclein in Parkinson's show a stereotypical sequential distribution pattern with progressing disease. In this review, we discuss recent evidence that TDP-43 in ALS may propagate similarly to other neurodegenerative disease proteins. We furthermore delineate similarities and important differences of TDP-43 proteinopathies to prion diseases.

Abstract
Angiogenesis is the formation of new blood vessels from pre-existing vessels and normally occurs during the process of inflammatory reactions, wound healing, tissue repair, and restoration of blood flow after injury or insult. Stimulation of angiogenesis is a promising and an important step in the treatment of peripheral artery disease. Reactive oxygen species have been shown to be involved in stimulation of this process. For this reason, we have developed and validated a non-equilibrium atmospheric temperature and pressure short-pulsed dielectric barrier discharge plasma system, which can non-destructively generate reactive oxygen species and other active species at the surface of the tissue being treated. We show that this plasma treatment stimulates the production of vascular endothelial growth factor, matrix metalloproteinase-9, and CXCL 1 that in turn induces angiogenesis in mouse aortic rings in vitro. This effect may be mediated by the direct effect of plasma generated reactive oxygen species on tissue.

Abstract
Cerebrospinal fluid (CSF) analysis is of utmost importance to establish an early diagnosis of central nervous system (CNS) infections and to start appropriate therapy. The CSF white cell count, lactate concentration and total protein levels are usually available very quickly even from non-specialized laboratories and the combination of these parameters often provides sufficient information for decision-making in emergency cases. It is, however, not always possible to identify the underlying infective agent despite further CSF analyses, such as bacterial and fungal staining, evaluation of the blood-CSF barrier function, intrathecal immunoglobulin synthesis and oligoclonal IgG bands. Therefore, close communication between the laboratory and the clinician is an important prerequisite to specify additional pathogen-related diagnostic measures for successful confirmation of the diagnosis.

Abstract
BACKGROUND In neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), CSF biomarkers are increasingly studied to evaluate their relevance for differential diagnosis, disease progression, and understanding of pathophysiologic processes. OBJECTIVE To identify a biomarker profile of neuronal and glial CSF proteins to discriminate ALS from other motor neuron diseases (MND) and to assess whether baseline levels of CSF measures in ALS are associated with the course of the disease. METHODS A total of 122 consecutive subjects with MND were included in this cross-sectional study (ALS, n = 75; lower motor neuron syndrome, n = 39; upper motor neuron diseases, n = 8). Clinical follow-up included 76 patients. We determined baseline levels of protein tau and astroglial S100beta in CSF and microglial sCD14 in CSF and serum in relation to diagnosis, duration of disease, and survival. RESULTS CSF tau was significantly elevated in ALS and upper motor neuron diseases as compared to lower motor neuron diseases and controls. CSF S100beta levels were significantly lower in lower motor neuron diseases as compared to other MND. CSF concentrations of S100beta and sCD14 correlated with the survival time in patients with ALS. CONCLUSIONS In motor neuron diseases, CSF tau elevation indicates the degeneration of upper motor neurons, while S100 beta and sCD14 may indicate the activation of CNS glial cells. Because S100beta and sCD14 concentrations correlate with survival in amyotrophic lateral sclerosis (ALS), we suppose that the combination of both markers may be useful to obtain prognostic information in patients with ALS.

Abstract
BACKGROUND Amnestic Mild Cognitive Impairment (MCI) is a condition with an increased risk for developing Alzheimer's disease (AD). Presently, gender differences are neglected in the assessment of MCI and AD. METHODS We examined verbal and visuospatial episodic memory in 143 subjects diagnosed as healthy controls (HC; N = 48, Mini-Mental State Examination (MMSE) 29.2 +/- 1.0 (mean +/- standard deviation)), MCI (N = 43,MMSE 28.5 +/- 1.4), and AD (N = 49, MMSE 25.1 +/- 2.2). FINDINGS Female HC and MCI subjects performed better on verbal episodic memory tasks than males. In contrast, visuospatial episodic memory was better in male than female AD patients. CONCLUSIONS We interpret the results in light of a gender-specific cognitive reserve and conclude that the gender-specificity of neuropsychological performance needs to be accounted for in clinical diagnosis of Alzheimer's disease.

Abstract
Cerebrospinal fluid (CSF) proteins may provide important information about the pathomechanisms present in multiple sclerosis (MS). Although diagnostic criteria for early MS are available, there is still a need for biomarkers, predicting disease subtype and progression to improve individually tailored treatment. Using the two-dimensional difference gel electrophoresis (2-D-DIGE) technology for comparative analysis, we compared CSF samples from patients with MS of the relapse-remitting type (RRMS, n = 12) and from patients with clinically isolated syndrome (CIS, n = 12) suggestive of a first demyelinating attack with neurologically normal controls. Protein spots that showed more than two-fold difference between patients and controls were selected for further analysis with MALDI-TOF mass spectrometry. Immunoblot analysis was performed to confirm the validity of individual candidate proteins. In RRMS, we identified 1 up-regulated and 10 down-regulated proteins. In CIS, 2 up-regulated and 11 down-regulated proteins were identified. One of these proteins (Apolipoprotein A1) was confirmed by immunoblot. Though the pathophysiological role of these proteins still remains to be elucidated in detail and further validation is needed, these findings may have a relevant impact on the identification of disease-specific markers.

Abstract
We used two-dimensional difference in-gel electrophoresis (2-D-DIGE) for proteome analysis of cerebrospinal fluid (CSF) in Guillain-Barré syndrome (GBS). Spots showing >2-fold difference between GBS and controls were analysed using MALDI-TOF mass spectrometry. Proteins that were up-regulated in GBS included haptoglobin, serine/threonine kinase 10, alpha-1-antitrypsin, SNC73, alpha II spectrin, IgG kappa chain and cathepsin D preprotein, while transferrin, caldesmon, GALT, human heat shock protein 70, amyloidosis patient HL-heart-peptide 127aa and transthyretin were down-regulated. Some of these proteins are reported in CSF of GBS for the first time. Accordingly, the 2-D-DIGE technology may be useful to identify disease-specific proteins in patients with GBS.

Abstract
OBJECTIVE To test whether biomarkers for axonal degeneration correlated with clinical subtypes and were of use in predicting progression of ALS. METHODS Patients with ALS (n = 69), patients with Alzheimer disease (AD; n = 73), and age-matched controls (n = 33) were included in this prospective study. CSF levels of tau protein and neurofilaments (NfHSMI35) were measured using ELISA. In 49 patients with ALS, follow-up data were available (median follow-up 7 months). RESULTS CSF levels of NfHSMI35 were five times higher in patients with ALS (1.7 ng/mL) than in controls (0.3 ng/mL, p < 0.001) and 10 times higher than in patients with AD (0.14 ng/mL, p < 0.001). NfHSMI35 values were also higher in patients with upper motor neuron-dominant ALS than in patients with typical ALS (upper motor neuron + lower motor neuron) at p = 0.02. Values of NfHSMI35 were higher in ALS of more rapid progression. The values of NfH and tau did not correlate with CSF protein content. CONCLUSIONS The authors propose that axonal damage markers in CSF may discriminate between subtypes of ALS and that they could be used as markers for therapeutic trials. CSF NfH was superior to tau in these discriminations.

Abstract
Thirty patients with multiple sclerosis were randomized to 500 or 2,000 mg of methylprednisolone (MP) over 5 days. They were prospectively studied neuropsychologically before and at days 6 and 60 after onset of the therapy, using a double-blind study design. Patients showed selective deterioration of declarative memory retrieval at day 6, which was fully reversible at day 60. Although the sample size was small, these effects were independent of the administered MP dose.

Abstract
OBJECTIVE An isolated dysfunction of the blood-CSF barrier is characterised by an abnormal elevation of the albumin CSF/serum concentration ratio (Q(alb)) without any other pathological CSF findings. Although common in routine CSF analysis, the clinical significance of an isolated barrier dysfunction frequently remains unclear. We examined neurological disorders associated with an isolated elevation of Q(alb) to identify possible determinants of blood-CSF barrier dysfunction. METHODS 367 patients (124 women, 243 men, median age 60. 0 years) out of 3,873 patients receiving diagnostic lumbar puncture at the University Hospital of Ulm (Germany) showed an isolated dysfunction of the blood-CSF barrier. Clinical data as well as MRI findings of these patients were analysed. RESULTS Isolated barrier dysfunction occurred most frequently (> 30%) in Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy (CIDP), normal pressure hydrocephalus (NPH), lumbar spinal stenosis, and polyneuropathy (PNP). In patients who showed no other evidence of neurological disease, isolated barrier dysfunction was found in 14. 9% of cases. The extent of barrier dysfunction was most prominent in brain tumours, GBS, and CIDP. There was a significant correlation of Q(alb) with both weight and body mass index (BMI). CONCLUSIONS Although isolated barrier dysfunction may be found in a variety of neurological diseases, it is especially frequent in GBS, CIDP, NPH, spinal canal stenosis, and PNP. In these patients, disease-related mechanisms contributing to barrier dysfunction are likely. Moreover, barrier function seems to be influenced by disease-independent determinants like weight and BMI.

Abstract
OBJECTIVES In animal models and in vitro studies leptomeninges have been shown to be the origin of neurotrophic substances that support the survival and growth of neuronal cells. Because dementia is associated with neuronal loss, we investigated whether leptomeningeal dysfunction may be involved in the pathogenesis of dementia disorders. METHODS We analysed the cerebrospinal fluid (CSF) concentrations of the leptomeningeal derived beta trace protein, beta2 microglobulin, and cystatin C. RESULTS There was a statistically significant difference of the CSF beta trace protein levels among different groups. Patients with idiopathic normal pressure hydrocephalus (NPH) (17.5 (SD 4.3) mg/l) showed significantly lower CSF beta trace protein levels than patients with Alzheimer's disease (23.8 (6.2) mg/l), depression (24.2 (7.3) mg/l), and normal controls (25.3 (4.9) mg/l). To patients with vascular dementia (20.1 (5.6) mg/l) and frontotemporal dementia (21.9 (7.0) mg/l), the difference was not significant. There was no significant difference regarding the CSF and serum concentrations of beta2 microglobulin or cystatin C among the different groups. CONCLUSIONS We conclude that leptomeningeal dysfunction may be involved in certain types of dementia such as NPH and that reduced CSF beta trace protein levels in patients with NPH may aid in differentiating this difficult to diagnose disorder from other syndromes such as Alzheimer's disease.

Abstract
AIM The purpose of this study was to determine the important predisposing factors associated with heterotopic ossifications (HO) after total hip arthroplasty. METHOD 589 patients were examined 6 months after primary total hip arthroplasty with regard to periarticular ossifications. Several predetermining factors were evaluated using the hospitalization records and preoperative X-ray examination. RESULTS A significantly increased frequency of heterotopic ossifications was found for male gender, patients with very high body mass index (BMI), low preoperative range of motion (ROM), long duration of operation and large preexistent osteophytes (p < 0.05). Only one out of the one hundred patients with an BMI < 22.6 developed severe HO (Brooker III). Out of the one hundred patients with the best preoperative ROM (> or = 140 degrees ) only one case developed severe ossifications (Brooker III). There was no correlation with the use of acrylic bone cement or the patient's age. The frequency of HO was significantly reduced both as well by nonsteroidal antiinflammatory drugs as from postoperative radiation prophylaxis. CONCLUSION In patients undergoing total hip arthroplasty with low preoperative ROM in the hip joint, large osteophytes and a very high BMI an efficient prophylaxis against HO is of great importance.

Abstract
The soluble form of the CD14 molecule (sCD14), a macrophage activity marker, was measured in the plasma of 17 patients with primary progressive multiple sclerosis (PPMS) and 20 patients with relapsing remitting MS (RRMS). In patients with PPMS, sCD14 levels were determined before and after treatment with interferon beta (IFNB). In both PPMS and in RRMS, sCD14 levels were significantly elevated compared to healthy controls. In patients with PPMS, sCD14 levels increased significantly during the first 3 months of IFNB therapy, then slightly decreased, but still remained elevated compared with levels before therapy. Therefore, the elevated sCD14 levels may be a marker in evaluating biological response to IFNB therapy.
