Bone marrow-derived mononuclear cell therapy in experimental pulmonary and extrapulmonary acute lung injury

Objective:To hypothesize that bone marrow-derived mononuclear cell (BMDMC) therapy might act differently on lung and distal organs in models of pulmonary or extrapulmonary acute lung injury with similar mechanical compromises. The pathophysiology of acute lung injury differs according to the type of primary insult. Design:Prospective, randomized, controlled, experimental study. Setting:University research laboratory. Measurements and Main Results:In control animals, sterile saline solution was intratracheally (0.05 mL) or intraperitoneally (0.5 mL) injected. Acute lung injury animals received Escherichia coli lipopolysaccharide intratracheally (40 μg, ALIp) or intraperitoneally (400 μg, ALIexp). Six hours after lipopolysaccharide administration, ALIp and ALIexp animals were further randomized into subgroups receiving saline (0.05 mL) or BMDMC (2 × 106) intravenously. On day 7, BMDMC led to the following: 1) increase in survival rate; 2) reduction in static lung elastance, alveolar collapse, and bronchoalveolar lavage fluid cellularity (higher in ALIexp than ALIp); 3) decrease in collagen fiber content, cell apoptosis in lung, kidney, and liver, levels of interleukin-6, KC (murine interleukin-8 homolog), and interleukin-10 in bronchoalveolar lavage fluid, and messenger RNA expression of insulin-like growth factor, platelet-derived growth factor, and transforming growth factor-&bgr; in both groups, as well as repair of basement membrane, epithelium and endothelium, regardless of acute lung injury etiology; 4) increase in vascular endothelial growth factor levels in bronchoalveolar lavage fluid and messenger RNA expression in lung tissue in both acute lung injury groups; and 5) increase in number of green fluorescent protein-positive cells in lung, kidney, and liver in ALIexp. Conclusions:BMDMC therapy was effective at modulating the inflammatory and fibrogenic processes in both acute lung injury models; however, survival and lung mechanics and histology improved more in ALIexp. These changes may be attributed to paracrine effects balancing pro- and anti-inflammatory cytokines and growth factors, because a small degree of pulmonary BMDMC engraftment was observed.
An intervention trial to improve adherence to community treatment by adolescents after a suicide attempt.

OBJECTIVE To determine whether a problem-solving intervention would increase adherence to outpatient treatment for adolescents after a suicide attempt. METHOD Sixty-three adolescents who had attempted suicide and were evaluated in an emergency department between 1997 and 2000 were randomly assigned to undergo standard disposition planning or a compliance enhancement intervention using a problem-solving format. At 3 months after the intervention, all evaluable adolescents, guardians, and outpatient therapists were contacted to determine adherence to outpatient treatment. RESULTS At 3-month follow-up, the compliance enhancement group attended an average of 7.7 sessions compared with 6.4 sessions for the standard disposition group, but this difference was not statistically significant. However, after covarying barriers to receiving services in the community (such as being placed on a waiting list and insurance coverage difficulties), the compliance enhancement group attended significantly more treatment sessions than the standard disposition-planning group (mean = 8.4 versus 5.8 sessions). CONCLUSION Interventions designed to improve treatment attendance must address not only individual and family factors but also service barriers encountered in the community that can impede access to services.
Urokinase‐type Plasminogen Activator Expression by Neurons and Oligodendrocytes During Process Outgrowth in Developing Rat Brain

The expression of tissue‐ and urokinase‐type plasminogen activators has been studied in developing cerebellum, hippocampus, cerebral cortex, olfactory bulb and olfactory mucosa of the rat by in situ hybridization. All identifiable neurons express urokinase mRNA from an early stage in their development, and this expression appears to coincide with the onset of axogenesis. For cerebellar granule cells, both axonal growth and urokinase expression are initiated before they migrate from the external granule layer; for the majority of neocortical neurons, however, both processes are commenced after the cells have migrated to the cortical plate. Neurons continue to express this protease in the adult. The large projection neurons exhibit the highest levels of message, the smaller interneurons having much lower levels except for hippocampal granule cells, which have notably high levels of expression. Glial cells generally do not express urokinase message, except for transient expression by oligodendrocytes in developing fibre tracts during the period of myelination. Thus for both neurons and oligodendrocytes, the onset of urokinase‐type plasminogen activator expression coincides with their initiation of major process outgrowth, although neurons maintain this expression in the adult, possibly to retain a degree of synaptic plasticity. In contrast, although high levels of message for the related protease, tissue plasminogen activator, are found in the embryonic floor plate, in postnatal brain it is abundantly expressed only by ventricular ependymal cells and by cells in connective tissue surrounding the olfactory nerve.
Synergy of molecular targeted approaches and immunotherapy in melanoma: preclinical basis and clinical perspectives

Introduction: Targeted therapy and immunotherapies are the novel pharmacologic treatment strategies for metastatic melanoma. BRAF and MEK inhibitors effectively block the hyperactivation of the MAPK pathway in BRAF mutant melanomas and also have several other effects on melanoma cells and on the immune response. The aim of this work is to discuss the rationale, evidence and perspectives of approaches combining target and immunotherapy against melanoma. Areas covered: We first review the effects of BRAF and MEK inhibitors on melanoma cells and on the different components of the immune system. Afterwards, we summarize the results of the preclinical and clinical studies that have combined targeted therapy and immunotherapy for the treatment of melanoma. Expert opinion: Clinical applications of immunotherapy strategies have recently changed the therapeutic mainstay for metastatic melanoma. Biologic and initial preclinical data support their integration with innovative molecular targeted therapies, opening enormous perspectives for researchers in the effort of finding a definitive cure. Main open challenges are the definition of reliable research models, assessment of effective schedules, safety issues and designing of personalized approaches.
Constructing Space and Self through Risk Taking: A Case of Asian Solo Female Travelers

In response to the increasingly risk-conscious environment in contemporary society, a growing body of literature has been dedicated to tourist risk perception. While risk is widely assumed to be a negative element in tourism, this perspective overlooks the fact that risk and tourist experience are intrinsically connected. This study takes a different approach by focusing on tourist risk-taking behavior, specifically, the risk perception and risk management of Asian solo female travelers, with an aim to contribute theoretical insights to the partial, conventional understanding of tourism risk. Located within a feminist framework, this study reveals how existing tourism space remains gendered and Western-dominated, how Asian women grapple with risks through various gendered spatial and bodily practices, and how negotiating risk is also a way to negotiate gender identities. A number of recommendations are provided for future research and for the tourism industry to foster a friendlier space for the Others.
Changes in Post-Traumatic Symptom Pattern during and after Exposure to Extreme War Stress: An Uncontrolled, Preliminary Study Supporting the Dose-Response Model

Abstract Introduction: Exposure to prolonged war stress is understudied. While there is debate regarding the empirical data of the dose-response model for post-traumatic stress disorder (PTSD), little is known about how weekly changes in external stress influences the level of PTSD symptoms. The purpose of this study was to measure the relation between objective external stress and PTSD symptoms across time, and thus, gain a deeper understating of the dose-response model. Hypothesis: The study hypothesis postulates that the more severe the external stressor, the more severe the exhibition of traumatic symptoms. Methods: Thirteen special army administrative staff (SAAS) members from the Rambam Medical Center in Haifa attended seven intervention meetings during the war. These personnel answered a battery of questionnaires regarding demographics and PTSD symptoms during each session. A non-parametric test was used in order to measure the changes in PTSD symptoms between sessions. Pearson correlations were used in order to study the relationship between the magnitude of external stressors and the severity of PTSD symptoms. Results: The results suggested that there was a significant relationship between the magnitude of external stressors and the severity of PTSD symptoms. These results are in line with the dose-response model. Conclusions: The results suggest that a pattern of decline in PTSD symptoms confirm the dose-response model for PTSD.
Aureobasidium pullulans fungal keratitis following LASEK.

PURPOSE To describe a patient who developed Aureobasidium pullulans keratitis following refractive laser epithelial keratomileusis (LASEK). METHODS A 52-year-old woman was referred to a tertiary care center 1 month after LASEK for treatment of a corneal ulcer that was unresponsive to conventional therapy. Mycology culture and fungal stain identified Aureobasidium as the infectious organism. RESULTS The infection responded well to treatment with topical natamycin and systemic itraconazole. CONCLUSIONS Treatment with topical natamycin and systemic itraconazole is effective against Aureobasidium pullulans keratitis.
The Effects of Teacher Experience on Budget Allocation and Student-Teacher Ratios: An analysis of the affects of teacher experience on student teacher ratios and budget allocation in Oregon School Districts

The economic literature exploring the potential negative externalities of teacher experience is minimal. To improve on that end we analyze the relationship between teacher experience and both its effect on marginalized categories of the school budget and on student-teacher ratios at the district level. In our analysis, we use a panel data set provided by the Oregon Department of Education spanning the years 2000-2014 across approximately 200 Oregon public school districts. We utilize logarithmic variations of the Ordinary Least Squares empirical models that control for socioeconomic and demographic differences, and include district and year fixed
Invasive breast cancer following ductal and lobular carcinoma in situ of the breast

We considered the risk of subsequent invasive breast cancer in a population‐based series of 579 carcinomas in situ (CIS) of the breast (482 ductal, 88 lobular) registered between 1977 and 2002 in the Swiss Canton of Vaud. A total of 55 cases of invasive breast cancer were observed vs. 12.3 expected, corresponding to a standardized incidence ratio (SIR) of 4.5 (95% confidence interval [CI], 3.4–5.8). The SIR was 4.6 after ductal and 4.2 after lobular CIS, was similar with passing time since CIS diagnosis, but was higher (SIR = 5.5) for women aged <55 years. At 20 years following CIS, the cumulative risk of invasive breast cancer was 26%, similar for lobular and for ductal CIS. The incidence of invasive breast cancer following CIS showed no consistent pattern of trends with age, all rates in subsequent age groups ranging between 10 and 18 in 1,000. This is compatible with the occurrence of a single mutational event in a population of susceptible women. © 2005 Wiley‐Liss, Inc.
From concept to reality: a decade of progress in regional ST-elevation myocardial infarction systems.

> Perseverance is not a long race: it is many short races one after another. > > —Walter Elliott, 19th Century spiritual writer The treatment and outcome of patients with ST-segment elevation myocardial infarction (STEMI) has improved dramatically over the 30 years since I graduated from medical school. In 1982, bed rest, treatment of complications such as ventricular arrhythmias or mural thrombus and prayer (for those so inclined) were the standard of care. In the first decade, pharmacological therapy was developed, and the open artery hypothesis was confirmed. The Second International Study of Infarct Survival (ISIS-2) trial demonstrated the benefit of not only aspirin, but also the combination of aspirin and streptokinase1 leading to a series of randomized clinical trials to determine the preferred fibrinolytic and adjunctive medications. The second decade was filled with trials that compared fibrinolytic therapy with primary percutaneous coronary intervention (PCI), which ultimately confirmed primary PCI as the preferred method of reperfusion if performed in a timely manner in high-volume centers.2 European trials extended the benefits of PCI to STEMI patients who presented to non-PCI centers requiring transfer for primary PCI.3,4 In particular, the Danish Multicenter Randomized Study on Thrombolytic Therapy versus Acute Coronary Angioplasty in Acute Myocardial Infarction (DANAMI-2), a well-designed, multicenter, randomized trial including 24 referral hospitals and 5 PCI centers in Denmark, was stopped early when it demonstrated a significant reduction in the primary end point of death, reinfarction, and stroke at 30 days (8% for primary PCI versus 13.7% for fibrinolysis, P <0.001). 4 Article see p 189 These randomized clinical trials stimulated interest in regional STEMI systems in the United States, but many believed it would be challenging to replicate the results seen in a small European country with short-duration transfers (mean, 34 miles) and an organized national emergency medical system (EMS). 5 In 2002, …
Lipooligosaccharide Structure Contributes to Multiple Steps in the Virulence of Neisseria meningitidis

ABSTRACT Lipooligosaccharide (LOS) of Neisseria meningitidis has been implicated in meningococcal interaction with host epithelial cells and is a major factor contributing to the human proinflammatory response to meningococci. LOS mutants of the encapsulated N. meningitidis serogroup B strain NMB were used to further determine the importance of the LOS structure in in vitro adherence and invasion of human pharyngeal epithelial cells by meningococci and to study pathogenicity in a mouse (CD46 transgenic) model of meningococcal disease. The wild-type strain [NeuNAc-Galβ-GlcNAc-Galβ-Glcβ-Hep2 (GlcNAc, Glcα) 3-deoxy-d-manno-2-octulosonic acid (KDO2)-lipid A; 1,4′ bisphosphorylated], although poorly adherent, rapidly invaded an epithelial cell layer in vitro, survived and multiplied early in blood, reached the cerebrospinal fluid, and caused lethal disease in the mouse model. In contrast, the Hep2 (GlcNAc) KDO2-lipid A (pgm) mutant, which was highly adherent to cultured epithelial cells, caused significantly less bacteremia and mortality in the mouse model. The Hep2-KDO2-lipid A (rfaK) mutant was shown to be moderately adherent and to cause levels of bacteremia and mortality similar to those caused by the wild-type strain in the mouse model. The KDO2-lipid A (gmhB) mutant, which lacks the heptose disaccharide in the inner core of LOS, avidly attached to epithelial cells but was otherwise avirulent. Disease development correlated with expression of specific LOS structures and was associated with lower adherence but rapid meningococcal passage to and survival in the bloodstream, induction of proinflammatory cytokines, and the crossing of the blood-brain barrier. Taken together, the results of this study further define the importance of the LOS structure as a virulence component involved in multiple steps in the pathogenesis of N. meningitidis.
Parasite Infections in Multiple Sclerosis Modulate Immune Responses through a Retinoic Acid–Dependent Pathway

We recently demonstrated better outcomes in helminth-infected multiple sclerosis (MS) patients, compared with uninfected ones. The present study evaluates the role of TLR2 and retinoic acid (RA) in parasite-driven protection in MS patients. RA serum levels were significantly higher in helminth-infected MS patients than in uninfected MS subjects or healthy controls. Genes involved in RA biosynthesis and metabolism, such as Adh1 and Raldh2, as well as RA receptors and IL-10, were induced in dendritic cells (DCs) via TLR2-dependent ERK signaling. This programmed DCs to induce FOXP3+ T regulatory cells and suppressed production of proinflammatory cytokines (IL-6, IL-12, IL-23, and TNF-α) via induction of suppressor of cytokine signaling 3 (SOCS3), an effect mediated by soluble egg Ag (SEA) obtained from Schistosoma mansoni, and by RA. SEA-activated DCs also inhibited IL-17 and IFN-γ production through autoreactive T cells. These inhibitory effects were abrogated when SOCS3 gene expression was silenced, indicating that SEA-mediated signaling inhibited production of these cytokines by T cells, through a SOCS3-dependent pathway. Overall, helminth-related immunomodulation observed in MS patients was mediated by TLR2- and RA-dependent pathways, through two different mechanisms, as follows: 1) induction of IL-10 and FOXP3+ T regulatory cells, and 2) suppression of proinflammatory cytokine production mediated by SOCS3.
Human perception of quadruped motion

In our research we are interested in human sensitivity to differences in animal gaits. We use point light walkers as stimuli, and follow up with a study using a realistic 3D model. Previously it has been shown that humans can regonise human motion, gender and the identity of an actor from a set of moving points [1973; 1977]. McDonnell et al. [2008] show that both shape and motion influence sex perception of virtual human characters. Mather and West [1993] have shown that people can recognise animals from pointlight displays. In order to find out whether we can tell the difference between animals using motion cues, we captured the motion of farm animals.
Does the Cytotoxic Effect of Transient Amyloid Oligomers from Common Equine Lysozyme in Vitro Imply Innate Amyloid Toxicity?*

In amyloid diseases, it is not evident which protein aggregates induce cell death via specific molecular mechanisms and which cause damage because of their mass accumulation and mechanical properties. We showed that equine lysozyme assembles into soluble amyloid oligomers and protofilaments at pH 2.0 and 4.5, 57 °C. They bind thioflavin-T and Congo red similar to common amyloid structures, and their morphology was monitored by atomic force microscopy. Molecular volume evaluation from microscopic measurements allowed us to identify distinct types of oligomers, ranging from tetramer to octamer and 20-mer. Monomeric lysozyme and protofilaments are not cytotoxic, whereas the oligomers induce cell death in primary neuronal cells, primary fibroblasts, and the neuroblastoma IMR-32 cell line. Cytotoxicity was accessed by ethidium bromide staining, MTT reduction, and TUNEL assays. Primary cultures were more susceptible to the toxic effect induced by soluble amyloid oligomers than the neuroblastoma cell line. The cytotoxicity correlates with the size of oligomers; the sample incubated at pH 4.5 and containing larger oligomers, including 20-mer, appears to be more cytotoxic than the lysozyme sample kept at pH 2.0, in which only tetramers and octamers were found. Soluble amyloid oligomers may assemble into rings; however, there was no correlation between the quantity of rings in the sample and its toxicity. The cytotoxicity of transient oligomeric species of the ubiquitous protein lysozyme indicates that this is an intrinsic feature of protein amyloid aggregation, and therefore soluble amyloid oligomers can be used as a primary therapeutic target and marker of amyloid disease.
Assessment of memory function: the relation between daily observation and neuropsychological test performance

ABSTRACT Background: The aim of the study was to explore the value of a daily observation scale in the assessment of patients' memory function by nurses on a geriatric ward. Methods: An observational study of 50 geriatric inpatients was carried out. The relationship between the memory items of the Nurses' Behavioral Rating Scale for Geriatric Inpatients (GIP) and four types of neuropsychological memory tests was examined: visual paired-associate learning (Visual Association Test, VAT), word-list learning (Eight Word Test, 8WT from the Amsterdam Dementia Screening, ADS), and the subtests Route Recall and Story Recall from the Rivermead Behavioural Memory Test (RBMT). Correlations with the overall measures assessing level of dementia such as the Mini-mental State Examination (MMSE), Clinical Dementia Rating scale (CDR) and the 15-item Geriatric Depression Scale (GDS-15) were examined as well. Results: The Pearson's correlation coefficients between GIP and the four memory tests were between 0.45 and 0.71 (p < 0.01). The GIP correlations with the MMSE and CDR were 0.63 and 0.46, respectively (p < 0.01). No significant correlation was found with the GDS-15. Statistically significant differences in GIP memory scores between patients with dementia and non-demented patients were found (p < 0.01). Conclusions: Results indicate that an observation scale of memory function may have value for providing information about the underlying memory impairment. The results of nurses' observations may be used in triage contributing to the diagnostic process by selecting patients requiring further neuropsychological assessment.
Cyber Frauds, Scams and their Victims

Crime is undergoing a metamorphosis. The online technological revolution has created new opportunities for a wide variety of crimes which can be perpetrated on an industrial scale, and crimes traditionally committed in an offline environment are increasingly being transitioned to an online environment. This book takes a case study-based approach to exploring the types, perpetrators and victims of cyber frauds. Topics covered include: - An in-depth breakdown of the most common types of cyber fraud and scams. - The victim selection techniques and perpetration strategies of fraudsters. - An exploration of the impact of fraud upon victims and best practice examples of support systems for victims. - Current approaches for policing, punishing and preventing cyber frauds and scams. This book argues for a greater need to understand and respond to cyber fraud and scams in a more effective and victim-centred manner. It explores the victim-blaming discourse, before moving on to examine the structures of support in place to assist victims, noting some of the interesting initiatives from around the world and the emerging strategies to counter this problem. This book is essential reading for students and researchers engaged in cyber crime, victimology and international fraud.
Revisiting the Design Issues of Local Models for Japanese Predicate-Argument Structure Analysis

The research trend in Japanese predicate-argument structure (PAS) analysis is shifting from pointwise prediction models with local features to global models designed to search for globally optimal solutions. However, the existing global models tend to employ only relatively simple local features; therefore, the overall performance gains are rather limited. The importance of designing a local model is demonstrated in this study by showing that the performance of a sophisticated local model can be considerably improved with recent feature embedding methods and a feature combination learning based on a neural network, outperforming the state-of-the-art global models in F1 on a common benchmark dataset.
