  7. Comprehensive Soldier Fitness and the future of psychology.

    Seligman, Martin E P; Fowler, Raymond D


    Psychology responded to the national needs in World War I and World War II and was itself transformed. National need calls a third time: unprecedented levels of posttraumatic stress disorder, depression, suicide, and anxiety along with a need for a resilient Army capable of meeting the persistent warfare of the foreseeable future. As a large part of the Comprehensive Soldier Fitness program, positive psychology is meeting this need with new tests, with new fitness courses, and with resilience training. These developments may transform the practice of psychology and psychology's relation to medicine and education.

  10. Health promotion research in active duty army soldiers: The road to a fit and ready force.

    McCarthy, Mary S; Elshaw, Evelyn B; Szekely, Barbara M; Pflugeisen, Bethann


    In the last decade the Military Health System has changed its paradigm to focus on health promotion and disease prevention. This paper reviews a decade of research exploring the effects of military life on nutritional status and bone health of Army soldiers. Descriptive and experimental approaches have assessed occupational demands on soldiers in variable environments that require optimal nutrition status and physical health. The prevalence of overweight and obesity in the military has risen dramatically and the implications for health, readiness, productivity, and cost demands attention. The related nutritional deficits such as suboptimal vitamin D status likely contribute to musculoskeletal injuries which have a greater impact on the performance and readiness of soldiers than any other medical condition in peacetime or conflict. The greatest challenge in our system for health is optimizing the performance of all soldiers while minimizing health risks and long-term disability resulting from occupational hazards, particularly those inherent to war.

  11. Efficacy of a pilot Internet-based weight management program (H.E.A.L.T.H.) and longitudinal physical fitness data in Army Reserve soldiers.

    Newton, Robert L; Han, Hongmei; Stewart, Tiffany M; Ryan, Donna H; Williamson, Donald A


    The primary aims of this article are to describe the utilization of an Internet-based weight management Web site [Healthy Eating, Activity, and Lifestyle Training Headquarters (H.E.A.L.T.H.)] over a 12-27 month period and to describe concurrent weight and fitness changes in Army Reserve soldiers. The H.E.A.L.T.H. Web site was marketed to Army Reserve soldiers via a Web site promotion program for 27 months (phase I) and its continued usage was observed over a subsequent 12-month period (phase II). Web site usage was obtained from the H.E.A.L.T.H. Web site. Weight and fitness data were extracted from the Regional Level Application Software (RLAS). A total of 1499 Army Reserve soldiers registered on the H.E.A.L.T.H. Web site. There were 118 soldiers who returned to the H.E.A.L.T.H. Web site more than once. Registration rate reduced significantly following the removal of the Web site promotion program. During phase I, 778 Army Reserve soldiers had longitudinal weight and fitness data in RLAS. Men exceeding the screening table weight gained less weight compared with men below it (p fitness scores. The Web site promotion program resulted in 52% of available Army Reserve soldiers registering onto the H.E.A.L.T.H. Web site, and 7.9% used the Web site more than once. The H.E.A.L.T.H. Web site may be a viable population-based weight and fitness management tool for soldier use. © 2011 Diabetes Technology Society.

  12. Even One Is Too Much: Sole Presence of One of the Risk Factors Overweight, Lack of Exercise, and Smoking Reduces Physical Fitness of Young Soldiers.

    Leyk, Dieter; Witzki, Alexander; Willi, Gorges; Rohde, Ulrich; Rüther, Thomas


    Health and physical fitness are key factors for soldiers. Increased sedentary military work, significant sitting periods during commuting and leisure time, and unhealthy dietary habits have caused a considerable increase in the number of physically unfit soldiers. Even worse, the adoption of harmful lifestyle habits occurs increasingly earlier in life. The aim of this cross-sectional study was (a) to determine the physical fitness of young male soldiers and (b) to investigate the association between physical fitness and both the presence and frequency of the health risk factors overweight, smoking, and lack of exercise. A total of 4,553 volunteers aged 18-25 years performed the Basis Fitness Test consisting of the 3 disciplines agility (11 × 10 m shuttle sprint), strength (flexed-arm hang), and endurance (1,000-m run). The presence and frequency of risk factors were determined by means of anthropometric measures (body mass index, waist circumference) and questionnaire data. The portion of soldiers without risk factors decreased from 49.4% (18-year-olds) to 16.4% for 25-year-olds. Persons without risk factors completed the agility test in 41.1 ± 3.7 seconds, flexed-arm hang in 60.1 ± 19.7 seconds, and 1,000-m run in 235 ± 32 seconds. Physical performance in all dimensions tested (agility, strength, endurance) notably deteriorated with the sole presence of one of the risk factors overweight, smoking, and lack of exercise. Any further risk factor led to further fitness decreases (p young male soldiers. Armed Forces must intensify their efforts to maintain health and performance of their soldiers.

  14. Soldier systems sensor fusion

    Brubaker, Kathryne M.


    This paper addresses sensor fusion and its applications in emerging Soldier Systems integration and the unique challenges associated with the human platform. Technology that,provides the highest operational payoff in a lightweight warrior system must not only have enhanced capabilities, but have low power components resulting in order of magnitude reductions coupled with significant cost reductions. These reductions in power and cost will be achieved through partnership with industry and leveraging of commercial state of the art advancements in microelectronics and power sources. As new generation of full solution fire control systems (to include temperature, wind and range sensors) and target acquisition systems will accompany a new generation of individual combat weapons and upgrade existing weapon systems. Advanced lightweight thermal, IR, laser and video senors will be used for surveillance, target acquisition, imaging and combat identification applications. Multifunctional sensors will provide embedded training features in combat configurations allowing the soldier to 'train as he fights' without the traditional cost and weight penalties associated with separate systems. Personal status monitors (detecting pulse, respiration rate, muscle fatigue, core temperature, etc.) will provide commanders and highest echelons instantaneous medical data. Seamless integration of GPS and dead reckoning (compass and pedometer) and/or inertial sensors will aid navigation and increase position accuracy. Improved sensors and processing capability will provide earlier detection of battlefield hazards such as mines, enemy lasers and NBC (nuclear, biological, chemical) agents. Via the digitized network the situational awareness database will automatically be updated with weapon, medical, position and battlefield hazard data. Soldier Systems Sensor Fusion will ultimately establish each individual soldier as an individual sensor on the battlefield.

  20. Building spiritual fitness in the Army: an innovative approach to a vital aspect of human development.

    Pargament, Kenneth I; Sweeney, Patrick J


    This article describes the development of the spiritual fitness component of the Army's Comprehensive Soldier Fitness (CSF) program. Spirituality is defined in the human sense as the journey people take to discover and realize their essential selves and higher order aspirations. Several theoretically and empirically based reasons are articulated for why spirituality is a necessary component of the CSF program: Human spirituality is a significant motivating force, spirituality is a vital resource for human development, and spirituality is a source of struggle that can lead to growth or decline. A conceptual model developed by Sweeney, Hannah, and Snider (2007) is used to identify several psychological structures and processes that facilitate the development of the human spirit. From this model, an educational, computer-based program has been developed to promote spiritual resilience. This program consists of three tiers: (a) building awareness of the self and the human spirit, (b) building awareness of resources to cultivate the human spirit, and (c) building awareness of the human spirit of others. Further research will be needed to evaluate the effectiveness of this innovative and potentially important program. (c) 2010 APA, all rights reserved.

  3. Soldier universal robot controller

    Hyams, Jeffrey; Batavia, Parag; Liao, Elizabeth; Somerville, Andrew


    The Soldier Universal Robot Controller (SURC) is a modular OCU designed for simultaneous control of heterogeneous unmanned vehicles. It has a well defined, published API., defined using XML schemas, that allows other potential users of the system to develop their own modules for rapid integration with SURC. The SURC architecture is broken down into three layers: User Interface, Core Functions, and Transport. The User Interface layer is the front end module which provides the human computer interface for user control of robots. The Core layer is further divided into the following modules: Capabilities, Tactical, Mobility, and World Model. The Capabilities module keeps track of the known robots and provides a list of specifications and services. The Mobility module provides path planning via D*, while the Tactical module provides higher level mission planning (multi-agent/multi-mission) capabilities for collaborative operations. The World Model module is a relational database which stores world model objects. Finally, a Transport module provides translation from the SURC architecture to the robot specific messaging protocols (such as JAUS). This allows fast integration of new robot protocols into an existing SURC implementation to enable a new system to rapidly leverage existing SURC capabilities. The communication between different modules within the SURC architecture is done via XML. This gives developers and users the flexibility to extend existing messages without breaking backwards compatibility. The modularity of SURC offers users and developers alike the capability to create custom modules and plug them into place, as long as they follow the pre defined messaging API for that module.

It has been established that the growing number of soldiers in military reserve with changes in health and physical condition indicates insufficient level of their health which has a negative impact on their capability and gradually on their fitness for military service. Priorities of changes in organization of the process of completion by human resources of the soldiers' military reserve in the Armed Forces of Ukraine during their transition towards professional army have been defined, to include optimization of criteria of fitness for military service.

  6. IIH with normal CSF pressures?

    Soh Youn Suh


    Full Text Available Idiopathic intracranial hypertension (IIH is a condition of raised intracranial pressure (ICP in the absence of space occupying lesions. ICP is usually measured by lumbar puncture and a cerebrospinal fluid (CSF pressure above 250 mm H 2 O is one of the diagnostic criteria of IIH. Recently, we have encountered two patients who complained of headaches and exhibited disc swelling without an increased ICP. We prescribed acetazolamide and followed both patients frequently; because of the definite disc swelling with IIH related symptoms. Symptoms and signs resolved in both patients after they started taking acetazolamide. It is generally known that an elevated ICP, as measured by lumbar puncture, is the most important diagnostic sign of IIH. However, these cases caution even when CSF pressure is within the normal range, that suspicion should be raised when a patient has papilledema with related symptoms, since untreated papilledema may cause progressive and irreversible visual loss.

    Granulocyte-colony stimulating factor (G-CSF) is commonly used in bone marrow transplant donors to increase the number of circulating progenitor cells. G-CSF has also been studied following myocardial infarction, but concern has been raised about the risks of G-CSF administration in patients with coronary artery disease. We present two cases of ischemic cardiac complications that are likely to be related to administration of G-CSF and provide a contemporary overview of the literature on the cardiovascular risks of G-CSF.

  8. "Once a Soldier, a Soldier Forever": Exiled Zimbabwean Soldiers in South Africa.

    Maringira, Godfrey; Carrasco, Lorena Núñez


    Through military training, soldiers' bodies are shaped and prepared for war and military-related duties. In the context these former Zimbabwean soldiers find themselves--that of desertion and 'underground life' in exile in South Africa--their military-trained bodies and military skills are their only resource. In this article, we explore the ways in which former soldiers maintain and 'reuse' their military-trained bodies in South Africa for survival, in a context of high unemployment and a violent, inner-city environment. We look at their social world and practices of soldiering--a term that refers to the specific forms of their social interaction in exile, through which they keep their memories of their military past alive. By attending to their subjectivities and the endurance of their masculine military identities and bodies, we aim to contribute to the discussion on demilitarization, which has largely focused on the failure of models of intervention to assist ex-combatants in postconflict contexts.

  9. Giving Work a Rain Check: Relationship Between Soldiering and Positive Work Outcomes Within the Job Demands-Resources Model

    Ümit Baran Metin


    Full Text Available Soldiering is defined as engaging behaviourally or cognitively into non-work-related activities during working hours with no intention of harming the employer, co-workers, and/or clients. The present study will investigate this phenomenon using the Job-Demands Resources Model. The proposed model will consider the influence of job demands and resources on soldiering, as well as the relationship of soldiering with employee wellbeing and performance. The data, collected via online questionnaires across seven European countries, will be analysed using structural equation modelling in order to explore the goodness-of-fit of the proposed model as well as its potential cross cultural variations.

    This article takes a point of departure in Denmark’s decision to use the armed forces as a tool of foreign policy, even when this implies deployment to regions where combat and casualties must be expected. Since war, combat, and violence contradict traditional self-understandings of being Danish....... All memorials, I argue, relate to a recent public discourse about the ‘war-fighting nation’ and the ‘warrior generation’. The national monument eschews references to war and violence to produce a national narrative focusing on ‘effort’ as the core collective value. One grassroots memorial subtly...... have been designed by the soldiers and their families, memorialize soldiers as professionals with a military belonging as well as persons with numerous social attachments. And they most directly address the war, violence, and suffering that the emergence of a ‘war-fighting nation’ and a ‘warrior...

  12. Heavy context dependence --- decisions of underground soldiers

    Kułakowski, K; Krawczyk, M J


    An attempt is made to simulate the disclosure of underground soldiers in terms of theory of networks. The coupling mechanism between the network nodes is the possibility that a disclosed soldier is going to disclose also his acquaintances. We calculate the fraction of disclosed soldiers as dependent on the fraction of those who, once disclosed, reveal also their colleagues. The simulation is immersed in the historical context of the Polish Home Army under the communist rule in 1946-49.

    Objective:To explore the fundamental theory, methods and data of the quality of life (QOL) of soldiers and its influence factors in the first response army. Methods :Totally 215 soldiers in the first response army of a military area in China were inquired by using self-regulating questionnaire and WHOQOL-BREF (Chinese Edition). Results:WHOQOL-BREF had good acceptability, reliability and validity in the first response army. QOL of soldiers in the first response army was middling. The influencing factors of QOL of the soldiers in first army includes self-report health, different areas where the army men come from, different arms of services, whether only child in family. And the difference was statistically significant. Conclusion:WHOQOL-BREF is fit for evaluating the quality of life of soldiers in the first response army. There are differences of the quality of life among the soldiers in the first response army. So we should take appropriate measures to improve the soldiers' quality of life.

    Brænder, Morten; Andersen, Lotte Bøgh

    , by means of public service motivation, a concept developed within the public administration literature, we compare soldier and civilian motivation. The contribution of this paper is an analysis of whether and how Danish combat soldiers differs from other Danes in regard to public service motivation? Using...... surveys with similar questions, we find that soldiers are more normatively motivated to contribute to society than other citizens (higher commitment to the public interest), while their affectively based motivation is lower (lower compassion).

    Objective In this study, we aimed to determine the performance characteristics of toluidine red unheated serum test on cerebrospinal fluids (CSF-TRUST) as compared to venereal disease research laboratory test on cerebrospinal fluids (CSF-VDRL) for laboratory the diagnosis of neurosyphilis. Design A cross-sectional study. Setting Sexually transmitted infections (STIs) clinics. Participants and methods CSF and serum samples were collected from 824 individual STD clinic patients who have syphilis and are suspected to progress to neurosyphilis within a 9-month period. CSF-VDRL and CSF-TRUST were performed parallelly on the same day when collected. Treponema pallidum particle agglutination (TPPA) tests were also performed on the CSF and the serum samples, and biochemical analysis of the CSF samples was also performed. Results The overall agreement between CSF-TRUST and CSF-VDRL was 97.3%. The reactive ratios of the CSF samples were 22.1% by CSF-TRUST and 24.8% by CSF-VDRL, respectively. All CSF-TRUST-reactive cases were reactive in the CSF-VDRL. Twenty-two samples with CSF-TRUST-negative were tested CSF-VDRL-reactive with low titres (1 : 1 to 1 : 4). Over 97% of the double-reactive CSF samples (CSF-VDRL and CSF-TRUST) had an identical titre or a titre within a two-fold difference. The agreement of CSF-TPPA and CSF-VDRL was 71.9%. Similarly, the agreement of CSF-TPPA and CSF-TRUST was 69.2%. Conclusions Our results revealed that CSF-TRUST could be used as an option for CSF examination in settings without CSF-VDRL in place.

  1. Neoplastic Meningitis: How MRI and CSF Cytology Are Influenced by CSF Cell Count and Tumor Type

    P. Prömmel


    Full Text Available Background. Although CSF cytology and MRI are standard methods to diagnose neoplastic meningitis (NM, this complication of neoplastic disease remains difficult to detect. We therefore reevaluated the sensitivity of gadolinium (GD-enhanced MRI and cerebrospinal-fluid (CSF-cytology and the relevance of tumor type and CSF cell count. Methods. We retrospectively identified 111 cases of NM diagnosed in our CSF laboratory since 1990 with complete documentation of both MRI and CSF cytology. 37 had haematological and 74 solid neoplasms. CSF cell counts were increased in 74 and normal in 37 patients. Results. In hematological neoplasms, MRI was positive in 49% and CSF cytology in 97%. In solid tumors, the sensitivity of MRI was 80% and of cytology 78%. With normal CSF cell counts, MRI was positive in 59% (50% hematological, 72% solid malignancies and CSF cytology in 76% (92% in hematological, 68% in solid neoplasms. In cases of elevated cell counts, the sensitivity of MRI was 72% (50% for hematological, 83% for solid malignancies and of CSF cytology 91% (100% for haematological and 85% for solid neoplasms. 91% of cytologically positive cases were diagnosed at first and another 7% at second lumbar puncture. Routine protein analyses had a low sensitivity in detecting NM. Conclusions. The high overall sensitivity of MRI was only confirmed for NM from solid tumors and for elevated CSF cell counts. With normal cell counts and haematological neoplasms, CSF-cytology was superior to MRI. None of the analysed routine CSF proteins had an acceptable sensitivity and specificity in detecting leptomeningeal disease.

  3. Child Soldiers: Tropes of Innocence and Terror

    David Rosen


    Full Text Available The story of child soldiers in the Western imagination is a story of symbolic reversals. Where the image of the child soldier once denoted public virtue and the nobility of sacrifice, it now stands for virtually everything that is wrong with war. Children were frequently present in the military through much of the 19th century (Aries 1962, p. 193. But by the middle of the 19th century, most Western nations had begun to reduce or eliminate the presence of children in their armed forces. The change was slow and erratic, however, so that even during World War I the heroic and patriotic child soldier, typically a boy sailor or soldier, remained a central image in the ideology of war and conflict (Conley 2009.

  4. Load Carriage and the Female Soldier

    Venerina Johnson


    Full Text Available This paper reviews the physiological, biomechanical and health impacts of load carriage on the female soldier and extends to include issues acknowledged as impacting on the female athlete and hence the female soldier. Physiological factors such as fat mass, strength, aerobic endurance and biomechanical factors such as stride length and forward lean have the potential to increase the energy cost of load carriage and cause injury. The female athlete triad, iron deficiency, pelvic floor muscle dysfunction and military equipment issues can likewise reduce female soldier performance and increase injury risk. Research evidence is presented to inform the development and implementation of performance optimisation and injury prevention strategies. Discussed strategies include structured physical conditioning, improving nutrition and hydration practices and modification of load carriage equipment to meet female soldier requirements.

  7. Confirmed viral meningitis with normal CSF findings.

    Dawood, Naghum; Desjobert, Edouard; Lumley, Janine; Webster, Daniel; Jacobs, Michael


    An 18-year-old woman presented with a progressively worsening headache, photophobia feverishness and vomiting. Three weeks previously she had returned to the UK from a trip to Peru. At presentation, she had clinical signs of meningism. On admission, blood tests showed a mild lymphopenia, with a normal C reactive protein and white cell count. Chest X-ray and CT of the head were normal. Cerebrospinal fluid (CSF) microscopy was normal. CSF protein and glucose were in the normal range. MRI of the head and cerebral angiography were also normal. Subsequent molecular testing of CSF detected enterovirus RNA by reverse transcriptase PCR. The patient's clinical syndrome correlated with her virological diagnosis and no other cause of her symptoms was found. Her symptoms were self-limiting and improved with supportive management. This case illustrates an important example of viral central nervous system infection presenting clinically as meningitis but with normal CSF microscopy.

  8. Nutrition as a component of the performance triad: how healthy eating behaviors contribute to soldier performance and military readiness.

    Purvis, Dianna L; Lentino, Cynthia V; Jackson, Theresa K; Murphy, Kaitlin J; Deuster, Patricia A


    Nutrition is a critical element of Soldier health and performance. Food choices, meal timing, and dietary intake behaviors contribute to nutritional fitness. The objectives of this study were to describe Soldier dietary behaviors and quantify the association between healthy eating behaviors and demographic, lifestyle, and psychosocial factors. The Comprehensive Soldier and Family Fitness Global Assessment Tool (GAT) assesses emotional, social, family, and spiritual fitness. In 2012, 57 pilot questions were added to the GAT to create a physical dimension that included nutrition assessments. Participants included 13,858 Active Duty, Reserve, and National Guard Soldiers: 83% male; 85% enlisted; a mean age of 28±9 years. A Healthy Eating Score (HES-5) was calculated from 5 questions assessing frequency of fruit, vegetable, whole grain, dairy, and fish intake (Cronbach α=0.81). Associations between HES-5 and other dietary habits, physical activity patterns, and GAT psychosocial dimension scores were examined. Soldiers who ate breakfast regularly (6 times/week or more), drank 7 servings or more of water/day, and met weekly exercise recommendations were more likely to be in the highest HES-5 quartile than those who did not. Those who passed their Army Physical Fitness Test (APFT) in the top quartile were also more likely to report high HES-5 scores than those who failed (Phealthy anthropometric measures and the highest emotional, social, family, and spiritual fitness scores were also more likely to be in the top HES-5 quartile than those with unhealthy measures and with the lowest fitness scores (PHealthy dietary intake behaviors are associated with all dimensions of health, physical fitness, and psychosocial status.

  9. CSF concentration gradients of monoamine metabolites in patients with hydrocephalus.

    Malm, J; Kristensen, B; Ekstedt, J; Wester, P


    Concentration gradients of homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), and 3-methoxy-4-hydroxyphenylglycol (MHPG), were assessed in 762 successive CSF fractions (2 ml lumbar CSF) from 15 patients with the adult hydrocephalus syndrome (AHS) and 11 patients with hydrocephalus of other causes (mixed group). A mean volume of 49.6 (SD 11.8) ml CSF was removed in the AHS group and 56.4 (10.2) ml in the mixed group. The CSF was collected with a specially designed carousel fraction collector and the corresponding CSF dynamics were continuously registered by a constant pressure CSF infusion method. Pronounced gradients in CSF HVA and CSF 5-HIAA were seen in both patient groups in the first 25 ml of CSF removed. The concentration curves levelled off, despite the removal of larger amounts of CSF and stabilised at about twice the initial concentrations. This phenomenon has not been described before. Concentrations of HVA and 5-HIAA in the first CSF fraction correlated strongly with concentrations in fractions up to about 40 ml. A positive correlation between the first fraction of CSF HVA and CSF 5-HIAA concentrations and CSF outflow conductance was found in the AHS group. There was no gradient in MHPG. It is suggested that the rostrocaudal gradients in CSF HVA and 5-HIAA may be explained by a downward flow of CSF along the spinal cord with absorption of metabolites occurring during passage. Mixing of CSF from different CSF compartments, extraventricular production sites of CSF, clearance of metabolites to venous blood or extracellular fluid, and CSF outflow conductance are probably important determinants of the plateau phase in patients with hydrocephalus. It is concluded that lumbar CSF does not exclusively reflect the concentrations of HVA, 5-HIAA, or MHPG in the ventricles. It should be noted that these results obtained in patients with hydrocephalus may not be applicable to other groups of patients or normal subjects.

  11. Pharmacokinetic and -dynamic modelling of G-CSF derivatives in humans

    Scholz Markus


    Full Text Available Abstract Background The human granulocyte colony-stimulating factor (G-CSF is routinely applied to support recovery of granulopoiesis during the course of cytotoxic chemotherapies. However, optimal use of the drug is largely unknown. We showed in the past that a biomathematical compartment model of human granulopoiesis can be used to make clinically relevant predictions regarding new, yet untested chemotherapy regimen. In the present paper, we aim to extend this model by a detailed pharmacokinetic and -dynamic modelling of two commonly used G-CSF derivatives Filgrastim and Pegfilgrastim. Results Model equations are based on our physiological understanding of the drugs which are delayed absorption of G-CSF when applied to the subcutaneous tissue, dose-dependent bioavailability, unspecific first order elimination, specific elimination in dependence on granulocyte counts and reversible protein binding. Pharmacokinetic differences between Filgrastim and Pegfilgrastim were modelled as different parameter sets. Our former cell-kinetic model of granulopoiesis was essentially preserved, except for a few additional assumptions and simplifications. We assumed a delayed action of G-CSF on the bone marrow, a delayed action of chemotherapy and differences between Filgrastim and Pegfilgrastim with respect to stimulation potency of the bone marrow. Additionally, we incorporated a model of combined action of Pegfilgrastim and Filgrastim or endogenous G-CSF which interact via concurrent receptor binding. Unknown pharmacokinetic or cell-kinetic parameters were determined by fitting the predictions of the model to available datasets of G-CSF applications, chemotherapy applications or combinations of it. Data were either extracted from the literature or were received from cooperating clinical study groups. Model predictions fitted well to both, datasets used for parameter estimation and validation scenarios as well. A unique set of parameters was identified which

  12. rhCSF3 accelerates the proliferation of human melanocytes in culture through binding CSF3R and the expression of CSF3R transcripts.

    Lu, Yan; Guo, Ze; Zhou, Mei-Hua; Li, Xue; Sun, Jie; Gong, Qing-Li; Zhu, Wen-Yuan


    Melanogenic paracrine and autocrine cytokine networks have recently been discovered in vitro between melanocytes and other types of skin cells. Granulocyte colony-stimulating factor receptor (CSF3R) controls the survival, proliferation and differentiation of many kinds of cells, including neutrophils. To understand the function of CSF3R and recombinant human granulocyte colony-stimulating factor (rhCSF3) on melanocyte proliferation, this study compared the expression of CSF3R and the effects of rhCSF3 in primary human melanocytes, neutrophils and HEL 92.1.7 cells. The results show that CSF3R is localized in the cytoplasm and on cell membranes of melanocytes and neutrophils. The percentage of CSF3R(+) melanocytes was higher than CSF3R(+) HEL 92.1.7 cells, but was lower than CSF3R(+) neutrophils. Both CSF3R mRNA and CSF3R protein levels in melanocytes were higher than in HEL 92.1.7 cells, but were lower than in neutrophils. Treatment with rhCSF3 increased the proliferation of human melanocytes, but not their tyrosinase activity. Transcripts of CSF3R in human melanocytes, M14, A375 melanoma and A431 squamous cell carcinoma cells were also detected. Expression of the CSF3R V3 transcript was lower in melanocytes than in M14, A375 melanoma and A431 squamous cell carcinoma cells. In conclusion, rhCSF3 can promote melanocyte proliferation through CSF3R without affecting tyrosinase activity.

  15. Physiological and Medical Aspects That Put Women Soldiers at Increased Risk for Overuse Injuries.

    Epstein, Yoram; Fleischmann, Chen; Yanovich, Ran; Heled, Yuval


    Anthropometric and physiological factors place female soldiers at a disadvantage relative to male soldiers in most aspects of physical performance. Average aerobic and anaerobic fitness levels are lower in women than in men. Thus, women have a lower overall work capacity and must exert themselves more than men to achieve the same output. The lower weight and fat-free mass and the higher body fat of women are associated with lower muscle strength and endurance, placing them at a disadvantage compared with men in performing military tasks such as lifting and carrying weights, or marching with a load. Working at a higher percentage of their maximal capacity to achieve the same performance levels as men, women tire earlier. Their smaller size, skeletal anatomy, and different bone geometry also predispose women to a higher incidence of exercise-related injuries. Consequently, the attrition rate of female soldiers in combat units is higher than that of their male counterparts. This review summarizes the literature on gender-related physiological and anatomical differences that put female soldiers at an increased risk of exercise-related injuries.

  16. Soldier/robot team acoustic detection

    Young, Stuart H.; Scanlon, Michael V.


    The future battlefield will require an unprecedented level of automation in which soldier-operated, autonomous, and semi-autonomous ground, air, and sea platforms along with mounted and dismounted soldiers will function as a tightly coupled team. Sophisticated robotic platforms with diverse sensor suites will be an integral part of the Objective Force, and must be able to collaborate not only amongst themselves but also with their manned partners. The Army Research Laboratory has developed a robot-based acoustic detection system that will detect and localize on an impulsive noise event, such as a sniper's weapon firing. Additionally, acoustic sensor arrays worn on a soldier's helmet or equipment can enhance his situational awareness and RSTA capabilities. The Land Warrior or Objective Force Warrior body-worn computer can detect tactically significant impulsive signatures from bullets, mortars, artillery, and missiles or spectral signatures from tanks, helicopters, UAVs, and mobile robots. Time-difference-of-arrival techniques can determine a sound's direction of arrival, while head attitude sensors can instantly determine the helmet orientation at time of capture. With precision GPS location of the soldier, along with the locations of other soldiers, robots, or unattended ground sensors that heard the same event, triangulation techniques can produce an accurate location of the target. Data from C-4 explosions and 0.50-Caliber shots shows that both helmet and robot systems can localize on the same event. This provides an awesome capability - mobile robots and soldiers working together on an ever-changing battlespace to detect the enemy and improve the survivability, mobility, and lethality of our future warriors.

  17. Therapeutic applications of macrophage colony-stimulating factor-1 (CSF-1) and antagonists of CSF-1 receptor (CSF-1R) signaling.

    Hume, David A; MacDonald, Kelli P A


    Macrophage-colony stimulating factor (CSF-1) signaling through its receptor (CSF-1R) promotes the differentiation of myeloid progenitors into heterogeneous populations of monocytes, macrophages, dendritic cells, and bone-resorbing osteoclasts. In the periphery, CSF-1 regulates the migration, proliferation, function, and survival of macrophages, which function at multiple levels within the innate and adaptive immune systems. Macrophage populations elicited by CSF-1 are associated with, and exacerbate, a broad spectrum of pathologies, including cancer, inflammation, and bone disease. Conversely, macrophages can also contribute to immunosuppression, disease resolution, and tissue repair. Recombinant CSF-1, antibodies against the ligand and the receptor, and specific inhibitors of CSF-1R kinase activity have been each been tested in a range of animal models and in some cases, in patients. This review examines the potential clinical uses of modulators of the CSF-1/CSF-1R system. We conclude that CSF-1 promotes a resident-type macrophage phenotype. As a treatment, CSF-1 has therapeutic potential in tissue repair. Conversely, inhibition of CSF-1R is unlikely to be effective in inflammatory disease but may have utility in cancer.

  18. The promotion of breast cancer metastasis caused by inhibition of CSF-1R/CSF-1 signaling is blocked by targeting the G-CSF receptor.

    Swierczak, Agnieszka; Cook, Andrew D; Lenzo, Jason C; Restall, Christina M; Doherty, Judy P; Anderson, Robin L; Hamilton, John A


    Treatment options are limited for patients with breast cancer presenting with metastatic disease. Targeting of tumor-associated macrophages through the inhibition of colony-stimulating factor-1 receptor (CSF-1R), a key macrophage signaling pathway, has been reported to reduce tumor growth and metastasis, and these treatments are now in clinical trials. Here, we report that, surprisingly, treatment with neutralizing anti-CSF-1R and anti-CSF-1 antibodies, or with two different small-molecule inhibitors of CSF-1R, could actually increase spontaneous metastasis without altering primary tumor growth in mice bearing two independently derived mammary tumors. The blockade of CSF-1R or CSF-1 led to increased levels of serum G-CSF, increased frequency of neutrophils in the primary tumor and in the metastasis-associated lung, as well as increased numbers of neutrophils and Ly6C(hi) monocytes in the peripheral blood. Neutralizing antibody against the G-CSF receptor, which regulates neutrophil development and function, reduced the enhanced metastasis and neutrophil numbers that resulted from CSF-1R blockade. These results indicate that the role of the CSF-1R/CSF-1 system in breast cancer is far more complex than originally proposed, and requires further investigation as a therapeutic target.

  3. CSF-1R Inhibitor Development: Current Clinical Status.

    Peyraud, Florent; Cousin, Sophie; Italiano, Antoine


    Colony-stimulating factor 1 receptor (CSF-1R) and its ligands, CSF-1 and interleukin 34 (IL-34), regulate the function and survival of tumor-associated macrophages, which are involved in tumorigenesis and in the suppression of antitumor immunity. Moreover, the CSF-1R/CSF-1 axis has been implicated in the pathogenesis of pigmented villonodular synovitis (PVNS), a benign tumor of the synovium. As advanced or metastatic malignant solid tumors and relapsed/refractory PVNS remain unresolved therapeutic problems, new approaches are needed to improve the outcome of patients with these conditions. In solid tumors, targeting CSF-1R via either small molecules or antibodies has shown interesting results in vitro but limited antitumor activity in vivo. Concerning PVNS, clinical trials assessing CSF-1R inhibitors have revealed promising initial outcomes. Blocking CSF-1/CSF-1R signaling represents a promising immunotherapy approach and several new potential combination therapies for future clinical testing.

    The forceful induction of children as child soldiers is an abhorrent violation of human rights. It is very disturbing that while many children are forcibly recruited into armed conflicts, others actually volunteer, due to their nightmarish alternatives. Although the practice has recently gained worldwide attention, awareness alone will not end the…

  10. CSF monoamine metabolites, cholinesterases and lactate in the adult hydrocephalus syndrome (normal pressure hydrocephalus) related to CSF hydrodynamic parameters.

    Malm, J; Kristensen, B; Ekstedt, J; Adolfsson, R; Wester, P


    Monoamine metabolites, cholinesterases and lactic acid in lumbar cerebrospinal fluid (CSF) were investigated on patients with the adult hydrocephalus syndrome (idiopathic normal pressure syndrome; AHS, n = 15), Alzheimer's disease (AD, n = 14), multi-infarct dementia (MID, n = 13) and controls (n = 21). Patients had clinical and CSF hydrodynamic investigations. Monoamine concentrations were determined by reversed-phase liquid chromatography, cholinesterases and lactate were determined photometrically. In the AHS patients, CSF monoamine concentrations were not significantly different compared with controls, AD or MID patients. AHS and AD patients showed a similar reduction of CSF acetylcholinesterase activity compared with controls. Positive correlations were found in concentrations of CSF homovanillic acid, CSF 5-hydroxyindoleacetic acid and CSF lactic acid versus CSF outflow conductance (that is, resistance against CSF outflow) in the AHS patients. A similar pattern was observed in a subgroup of MID patients characterised by dilated ventricles and disturbed CSF hydrodynamics. These data suggest that a low CSF outflow conductance may facilitate the clearance of acidic substances from the arachnoid space at the probenecid sensitive active transport site. Alternative explanations would be that a pathologically low CSF outflow conductance is accompanied by an inverse caudorostral flow of CSF or a compromised trans-ependymal diffusion.

    de Leon, Mony J; Li, Yi; Okamura, Nobuyuki; Tsui, Wai H; Saint Louis, Les A; Glodzik, Lidia; Osorio, Ricardo S; Fortea, Juan; Butler, Tracy; Pirraglia, Elizabeth; Fossati, Silvia; Kim, Hee-Jin; Carare, Roxana O; Nedergaard, Maiken; Benveniste, Helene; Rusinek, Henry


    Evidence supporting the hypothesis that reduced cerebrospinal fluid (CSF) clearance is involved in the pathophysiology of Alzheimer's disease (AD) comes from primarily from rodent models. However, unlike rodents where predominant extra-cranial CSF egress is via olfactory nerves traversing the cribriform plate, human CSF clearance pathways are not well characterized. Using dynamic Positron Emission Tomography (PET) with (18)F-THK5117 a tracer for tau pathology, the ventricular CSF time activity was used as a biomarker for CSF clearance. We tested three hypotheses: 1. Extra-cranial CSF is detected at the superior turbinates; 2. CSF clearance is reduced in AD; and 3. CSF clearance is inversely associated with amyloid deposition. Methods: 15 subjects, 8 with AD and 7 normal control volunteers were examined with (18)F-THK5117. 10 subjects additionally received (11)C-PiB PET scans and 8 were PiB positive. Ventricular time activity curves (TAC) of (18)F-THK5117 were used to identify highly correlated TAC from extra-cranial voxels. Results: For all subjects, the greatest density of CSF positive extra-cranial voxels was in the nasal turbinates. Tracer concentration analyses validated the superior nasal turbinate CSF signal intensity. AD patients showed ventricular tracer clearance reduced by 23% and 66% fewer superior turbinate CSF egress sites. Ventricular CSF clearance was inversely associated with amyloid deposition. Conclusion: The human nasal turbinate is part of the CSF clearance system. Lateral ventricle and superior nasal turbinates CSF clearance abnormalities are found in AD. Ventricular CSF clearance reductions are associated with increased brain amyloid depositions. These data suggest that PET measured CSF clearance is a biomarker of potential interest in AD and other neurodegenerative diseases.

  13. Neurosyphilis in AIDS patients: initial CSF VDRL may be negative.

    Feraru, E R; Aronow, H A; Lipton, R B


    We report 2 HIV-seropositive patients with neurosyphilis whose initial CSF VDRL tests were negative. The CSF VDRL became positive after 12 days of IV penicillin treatment for syphilitic meningitis in the 1st patient. The 2nd patient developed syphilitic polyradiculopathy and a positive CSF VDRL 3 months after treatment with IV penicillin. Serial CSF VDRL determinations may be required in AIDS patients when a diagnosis of neurosyphilis is suspected.

  14. Chemokines in CSF of Alzheimer's disease patients

    Jôice Dias Corrêa


    Full Text Available Some studies have linked the presence of chemokines to the early stages of Alzheimer's disease (AD. Then, the identification of these mediators may contribute to diagnosis. Our objective was to evaluate the levels of beta-amyloid (BA, tau, phospho-tau (p-tau and chemokines (CCL2, CXCL8 and CXCL10 in the cerebrospinal fluid (CSF of patients with AD and healthy controls. The correlation of these markers with clinical parameters was also evaluated. The levels of p-tau were higher in AD compared to controls, while the tau/p-tau ratio was decreased. The expression of CCL2 was increased in AD. A positive correlation was observed between BA levels and all chemokines studied, and between CCL2 and p-tau levels. Our results suggest that levels of CCL2 in CSF are involved in the pathogenesis of AD and it may be an additional useful biomarker for monitoring disease progression.

  15. CSF Biomarkers for Alzheimer's Disease Diagnosis

    A. Anoop


    Full Text Available Alzheimer's disease (AD is the most common form of dementia that affects several million people worldwide. The major neuropathological hallmarks of AD are the presence of extracellular amyloid plaques that are composed of Aβ40 and Aβ42 and intracellular neurofibrillary tangles (NFT, which is composed of hyperphosphorylated protein Tau. While the amyloid plaques and NFT could define the disease progression involving neuronal loss and dysfunction, significant cognitive decline occurs before their appearance. Although significant advances in neuroimaging techniques provide the structure and physiology of brain of AD cases, the biomarker studies based on cerebrospinal fluid (CSF and plasma represent the most direct and convenient means to study the disease progression. Biomarkers are useful in detecting the preclinical as well as symptomatic stages of AD. In this paper, we discuss the recent advancements of various biomarkers with particular emphasis on CSF biomarkers for monitoring the early development of AD before significant cognitive dysfunction.

  18. Evaluation of the Performance of Females as Light Infantry Soldiers

    Aharon S. Finestone


    Full Text Available A few countries permit women to serve in combat roles, but their long term performance in these positions has not been reported. The incidences of overuse injuries and attrition of 85 male and 235 female recruits in a light infantry brigade was followed in a three-year prospective study. Females were shorter (162 cm, CI 161–163 cm than males (174 cm, CI 173–176, had more body fat (18.9 kg, CI 18.2–19.6 kg than males (12.6 kg, 11.3–13.8 kg, had lower V˙O2max (36.8 mL·min−1·kg−1, CI 35.8–37.78 mL·min−1·kg−1 than males (50.48 mL·min−1·kg−1, CI 48.4 to 52.48 mL·min−1·kg−1, had more stress fractures (21.0%, 95% CI 16.2–26.5% than males (2.3%, CI 0.3–8.2%, and had more anterior knee pain (41.2%, CI 34.9–47.7% than males (24.7%, CI 16.0–35.2%. Three-year attrition was 28% CI 22–34% for females and 37% CI 26–48% for males. The females in this study successfully served as light infantry soldiers. Their lower fitness and high incidence of overuse injuries might impede service as regular infantry soldiers.

  5. Cerebrospinal fluid (CSF 25-hydroxyvitamin D concentration and CSF acetylcholinesterase activity are reduced in patients with Alzheimer's disease.

    Per Johansson

    Full Text Available BACKGROUND: Little is known of vitamin D concentration in cerebrospinal fluid (CSF in Alzheimer's disease (AD and its relation with CSF acetylcholinesterase (AChE activity, a marker of cholinergic function. METHODS: A cross-sectional study of 52 consecutive patients under primary evaluation of cognitive impairment and 17 healthy controls. The patients had AD dementia or mild cognitive impairment (MCI diagnosed with AD dementia upon follow-up (n = 28, other dementias (n = 12, and stable MCI (SMCI, n = 12. We determined serum and CSF concentrations of calcium, parathyroid hormone (PTH, 25-hydroxyvitamin D (25OHD, and CSF activities of AChE and butyrylcholinesterase (BuChE. FINDINGS: CSF 25OHD level was reduced in AD patients (P < 0.05, and CSF AChE activity was decreased both in patients with AD (P < 0.05 and other dementias (P < 0.01 compared to healthy controls. None of the measured variables differed between BuChE K-variant genotypes whereas the participants that were homozygous in terms of the apolipoprotein E (APOE ε4 allele had decreased CSF AChE activity compared to subjects lacking the APOE ε4 allele (P = 0.01. In AD patients (n=28, CSF AChE activity correlated positively with CSF levels of total tau (T-tau (r = 0.44, P < 0.05 and phosphorylated tau protein (P-tau (r = 0.50, P < 0.01, but CSF activities of AChE or BuChE did not correlate with serum or CSF levels of 25OHD. CONCLUSIONS: In this pilot study, both CSF 25OHD level and CSF AChE activity were reduced in AD patients. However, the lack of correlations between 25OHD levels and CSF activities of AChE or BuChE might suggest different mechanisms of action, which could have implications for treatment trials.

  7. Psychological characteristics of Swedish mandatory enlisted soldiers volunteering and not volunteering for international missions: an exploratory study.

    Rydstedt, Leif W; Osterberg, Johan


    The purpose of this study was to assess personality traits, psychological fitness, and hardiness among conscript soldiers volunteering for international missions (n = 146), by comparing them with conscripts from the same year class and unit who did not apply for international missions (n = 275). The sample consisted of all mandatory enlisted soldiers assigned to a supply and maintenance regiment. There were no demographic differences between the groups. The volunteers reported greater stress tolerance, concern for others, extraversion, and self-confidence than the non-volunteers. There were no differences between the groups in orderliness, temper instability, or independence. Volunteers repeatedly reported greater psychological fitness for military missions and greater hardiness over the period of military service compared to the non-volunteers.

    Reproducibility of the aqueductal CSF signal intensity on a gradient echo cine-MR sequence exploiting through plane inflow enhancement was tested in 11 patients with normal or dilated ventricles. Seven patients with normal pressure hydrocephalus (NPH) syndrome were investigated with the sequence before and after CSF shunting. Two patients exhibiting central flow void within a hyperintense aqueductal CSF improved after surgery and the flow void disappeared after shunting. One patient with increased maximum and minimum aqueductal CSF signal as compared to 18 healthy controls also improved and the aqueductal CSF signal was considerably decreased after shunting. Three patients with aqueductal CSF values similar to those in the controls did not improve, notwithstanding their maximum aqueductal CSF signals decreasing slightly after shunting. No appreciable aqueductal CSF flow related enhancement consistent with non-communicating hydrocephalus was found in the last NPH patient who improved after surgery. Cine-MR with inflow technique yields a reproducible evaluation of flow-related aqueductal CSF signal changes which might help in identifying shunt responsive NPH patients. These are likely to be those with hyperdynamic aqueductal CSF or aqueductal obstruction. (orig.).

  9. Comparison of the cerebrospinal fluid (CSF) toluidine red unheated serum test and the CSF rapid plasma reagin test with the CSF venereal disease research laboratory test for diagnosis of neurosyphilis among HIV-negative syphilis patients in China.

    Zhu, Lin; Gu, Xin; Peng, Rui-Rui; Wang, Cuini; Gao, Zixiao; Zhou, Pingyu; Gao, Ying; Shi, Mei; Guan, Zhifang; Seña, Arlene C


    In this study, we aimed to investigate the performance of nontreponemal antibody tests in cerebrospinal fluid (CSF) specimens from syphilis patients. From September 2009 to September 2012, CSF specimens were collected at the Shanghai Skin Disease Hospital in Shanghai, China, from 1,132 syphilis patients without HIV infection, including 154 with symptomatic and 56 with asymptomatic neurosyphilis. All of the CSF specimens underwent testing with a rapid plasma reagin (RPR) test, an RPR-V (commercial RPR antigen diluted 1:2 in 10% saline) test, the toluidine red unheated serum test (TRUST), and the Venereal Disease Research Laboratory (VDRL) test. Specificities, sensitivities, positive predictive values (PPVs), negative predictive values (NPVs), and kappa values were calculated to determine the performances of the tests. We compared results of the CSF-VDRL, CSF-RPR, CSF-RPR-V, and CSF-TRUST among patients with symptomatic and asymptomatic neurosyphilis who had reactive CSF-Treponema pallidum particle agglutination (TPPA) test results. Overall, the CSF-VDRL test was reactive in 261 patients (23.1%). There were no cases in which the CSF-VDRL was nonreactive and CSF-RPR, CSF-RPR-V, or CSF-TRUST was reactive. Agreement between the results of CSF-TRUST and CSF-RPR was almost perfect (κ=0.861), with substantial agreement between the results of CSF-RPR and CSF-RPR-V (κ=0.740). The sensitivities of CSF-VDRL, CSF-RPR, CSF-RPR-V, and CSF-TRUST were 81.4%, 76.2%, 79.5%, and 76.2%, respectively. Compared to CSF-VDRL, CSF-RPR, CSF-RPR-V, and CSF-TRUST had comparable PPVs and NPVs. However, the specificity of CSF-VDRL (90.3%) was significantly lower than those of the other tests (92.7 to 93.4%). Therefore, CSF-RPR, CSF-RPR-V, and CSF-TRUST can be considered alternative tests for neurosyphilis diagnosis in HIV-negative populations, particularly when the CSF-VDRL is not available.

  13. Tyraminergic and Octopaminergic Modulation of Defensive Behavior in Termite Soldier.

    Yuki Ishikawa

    Full Text Available In termites, i.e. a major group of eusocial insects, the soldier caste exhibits specific morphological characteristics and extremely high aggression against predators. Although the genomic background is identical to the other non-aggressive castes, they acquire the soldier-specific behavioral character during the course of caste differentiation. The high aggressiveness and defensive behavior is essential for colony survival, but the neurophysiological bases are completely unknown. In the present study, using the damp-wood termite Hodotermopsis sjostedti, we focused on two biogenic amines, octopamine (OA and tyramine (TA, as candidate neuromodulators for the defensive behavior in soldiers. High-performance liquid chromatographic analysis revealed that TA levels in the brain and suboesophageal ganglion (SOG and the OA level in brain were increased in soldiers than in pseudergates (worker caste. Immunohistochemical analysis revealed that TA/OA neurons that innervate specific areas, including the mandibular muscles, antennal nerve, central complex, suboesophageal ganglion, and thoracic and/or abdominal ganglia, were enlarged in a soldier-specific manner. Together with the results that pharmacological application of TA promoted the defensive behavior in pseudergates, these findings suggest that the increased TA/OA levels induce the higher aggressiveness and defensive behavior in termite soldiers. The projection targets of these soldier-specific enlarged TA/OA neurons may have important roles in the higher aggressiveness and defensive behavior of the termite soldiers, inducing the neuronal transition that accompanies external morphological changes.

  19. Low CSF levels of both α-synuclein and the α-synuclein cleaving enzyme neurosin in patients with synucleinopathy.

    Malin Wennström

    Full Text Available Neurosin is a protease that in vitro degrades α-synuclein, the main constituent of Lewy bodies found in brains of patients with synucleinopathy including Parkinson's disease (PD and dementia with Lewy bodies (DLB. Several studies have reported reduced cerebrospinal fluid (CSF levels of α-synuclein in synucleinopathy patients and recent data also proposes a significant role of α-synuclein in the pathophysiology of Alzheimer's disease (AD. To investigate potential links between neurosin and its substrate α-synuclein in vivo we used a commercially available sandwich ELISA and an in-house developed direct ELISA to quantify CSF levels of α-synuclein and neurosin in patients diagnosed with DLB, PD and PD dementia (PDD versus AD patients and non-demented controls. We found that patients with synucleinopathy displayed lower CSF levels of neurosin and α-synuclein compared to controls and AD patients. In contrast, AD patients demonstrated significantly increased CSF α-synuclein but similar neurosin levels compared to non-demented controls. Further, CSF neurosin and α-synuclein concentrations were positively associated in controls, PD and PDD patients and both proteins were highly correlated to CSF levels of phosphorylated tau in all investigated groups. We observed no effect of gender or presence of the apolipoprotein Eε4 allele on neither neurosin or α-synuclein CSF levels. In concordance with the current literature our study demonstrates decreased CSF levels of α-synuclein in synucleinopathy patients versus AD patients and controls. Importantly, decreased α-synuclein levels in patients with synucleinopathy appear linked to low levels of the α-synuclein cleaving enzyme neurosin. In contrast, elevated levels of α-synuclein in AD patients were not related to any altered CSF neurosin levels. Thus, altered CSF levels of α-synuclein and neurosin in patients with synucleinopathy versus AD may not only mirror disease-specific neuropathological

  20. Psycho-physiological response of soldiers in urban combat

    Vicente J. Clemente-Suárez


    Full Text Available Current armed conflicts are asymmetrical and are developed m urban areas. These new requirements have not been studied for current literature. The aim of this study was to analyse changes in cortical arousal, blood lactate, muscle strength, autonomic modulation and rate of perceived exertion in a simulated urban combat. We analyzed 20 soldiers before and after an urban combat simulation. The results showed how urban combat produced high sympathetic nervous system activation, increasing the muscle strength, heart rate and blood lactate concentration of the soldiers. Despite this effort, rate of perceived exertion were not consistent with the physiological response that soldiers presented, the rate of perceived exertion was lower than the physiological response evaluated. Furthermore, the information processing and cortical arousal decreased after the urban combat simulation. These results have showed the psycho-physiological response of soldiers in combat, helping to better understanding and enabling an improvement of current training methods of soldiers.

  1. Integrated soldier power and data system (ISPDS)

    Ostroumov, Roman; Forrester, Thomas; Lee, Kang; Stephens, Robert; Lai, Anthony; Zahzah, Mohamad


    Physical Optics Corporation (POC) developed the body-worn Integrated Soldier Power and Data System (ISPDS), a configurable node for plug-in wired or wireless server/client or peer-to-peer computing with accommodations for power, sensor I/O interfaces, and energy harvesting. The enabling technology increases the efficacy of uniformed personnel and first responders and provides an option for reducing force structure associated with the need for hardware network infrastructure to enable a mobile digital communications architecture for dismounted troops. The ISPDS system addresses the DoD's need for an "intelligent" power control system in an effort to increase mission duration and maximize the first responders and warfighter's effectiveness without concern for the available energy resources (i.e., batteries). ISPDS maximizes durability and survivability, assesses influences that affect performance, and provides the network backbone and mobile node hardware. POC is producing two vest-integrated variants, one each for the U.S. Army PEO Ground Soldier and the Air Soldier, with each including state-of-the-art low-profile and robust wearable connectors, cabling, and harnesses, and an integrated low-profile power manager and conformal battery for data and power distribution. The innovative intelligent power controller (IPC), in the form of the ISPDS firmware and power sensing and control electronics, will enable ISPDS to optimize power levels both automatically and in accordance with manually set preferences. The IPC module is power dense and efficient, and adaptively provides lossless transfer of available harvested photovoltaic energy to the battery. The integrated systems were tested for suitable electrical, electromagnetic interference (EMI), and environmental performance as outlined in military standards such as MIL-STD- 810G and MIL STD-461F.

    Full Text Available Our study concerns contact sensitization in soldiers, the frequency of which is poorly documented. During a six-year period, 128 patients of age range 17-50 years were patch tested with the Indian standard battery of 30 allergens. We obtained a reaction in 23 (18% of our patients. Nickel sulfate, fragrance mix, wool alcohol and parthenium induced most of the positive responses. In addition, an irritant reaction was seen in 16 (12.5% of our patients. Patients of atopic dermatitis and hand/foot dermatoses evoked a high sensitivity response. Adverse effects were seen in 15 patients.

  3. Self-inflicted burns in soldiers.

    Gronovich, Yoav; Binenboym, Rami; Tuchman, Izhak; Eizenman, Nirit; Golan, Jacob


    Self-inflicted burns are a multidisciplinary medical challenge. In contrast to the more common motive of attempted suicide in self-infliction of a burn, usually of a serious degree, a second motive is malingering. Motivation of this nature has been exhibited among Israeli soldiers who inflict on themselves low- to moderate-degree burns to obtain dismissal from mandatory military service. The purpose of our study is to investigate and define this phenomenon. A retrospective analysis was performed on a population of 75 soldiers admitted to our Medical Center during the year 2010 with the diagnosis of any sort of burn. We set up a database including all relevant information about the burns including date and time of occurrence, cause, body location, depth of burn injury, area and shape of burn, etiology, and prescribed treatment. The summer was found to be the season with the highest incidence of burns. As far as the day of the week was influential, we found that the greater percentage of burns occurred at the beginning of the week. Most of the burns involved a minor surface area on the dorsal aspect of the foot. Scalding with hot water was the most common cause of burn. Eighty-one percent of the burns were atypical, being well demarcated.Most of the burn cases happened at home with no witnesses to the event. Sixty-one percent of the patients were not admitted to the hospital and were conservatively treated. Israeli soldiers tend to inflict burns on themselves for ulterior motives. Such burns are almost always minor with a small trauma area and sharp demarcations, and hence can be differentiated from other self-inflicted burns described in the literature. We found that most of the burns occur when the soldiers are on vacation at home. This is probably because the privacy allows them to carry out their act undisturbed. It is important to raise the awareness of attending physicians to the characteristics of these burns. Such patients should be evaluated by medical teams

  4. Child Soldiers: Children Associated with Fighting Forces.

    Song, Suzan J; de Jong, Joop


    Around the world, there are an estimated 300,000 to 500,000 children involved in armed conflict. Children can be abducted into a fighting force to fight or serve as sex slaves. Child soldiers have depression, anxiety, and posttraumatic stress symptoms; however, evidence is mixed because of methodologic limitations. Various mental health interventions have been tried, with promising results. Child and adolescent psychiatrists are uniquely trained in understanding and assisting youth to heal from such extraordinary experiences. A public health paradigm could include interventions that are based on a comprehensive assessment of interweaving developmental, biological, psychological, and sociocultural factors.

  5. CSF neurofilament concentration reflects disease severity in frontotemporal degeneration

    Scherling, Carole S.; Hall, Tracey; Berisha, Flora; Klepac, Kristen; Karydas, Anna; Coppola, Giovanni; Kramer, Joel H.; Rabinovici, Gil; Ahlijanian, Michael; Miller, Bruce L.; Seeley, William; Grinberg, Lea T.; Rosen, Howard; Meredith, Jere; Boxer, Adam L.


    Objective Cerebrospinal fluid (CSF) neurofilament light chain (NfL) concentration is elevated in neurological disorders including frontotemporal degeneration (FTD). We investigated the clinical correlates of elevated CSF NfL levels in FTD. Methods CSF NfL, amyloid-β42 (Aβ42), tau and phosphorylated tau (ptau) concentrations were compared in 47 normal controls (NC), 8 asymptomatic gene carriers (NC2) of FTD-causing mutations, 79 FTD (45 behavioral variant frontotemporal dementia [bvFTD], 18 progressive nonfluent aphasia [PNFA], 16 semantic dementia [SD]), 22 progressive supranuclear palsy, 50 Alzheimer’s disease, 6 Parkinson’s disease and 17 corticobasal syndrome patients. Correlations between CSF analyte levels were performed with neuropsychological measures and the Clinical Dementia Rating scale sum of boxes (CDRsb). Voxel-based morphometry of structural MR images determined the relationship between brain volume and CSF NfL. Results Mean CSF NfL concentrations were higher in bvFTD, SD and PNFA than other groups. NfL in NC2 was similar to NC. CSF NfL, but not other CSF measures, correlated with CDRsb and neuropsychological measures in FTD, and not in other diagnostic groups. Analyses in two independent FTD cohorts and a group of autopsy verified or biomarker enriched cases confirmed the larger group analysis. In FTD, gray and white matter volume negatively correlated with CSF NfL concentration, such that individuals with highest NfL levels exhibited the most atrophy. Interpretation CSF NfL is elevated in symptomatic FTD and correlates with disease severity. This measurement may be a useful surrogate endpoint of disease severity in FTD clinical trials. Longitudinal studies of CSF NfL in FTD are warranted. PMID:24242746

  6. CSF-endorphines in acute and chronic brain lesions.

    Hamel, E


    In order to answer the question of an opioid influence on consciousness, a radio-immuno-assay (n = 852) of beta-endorphin and beta-LPH (beta-lipotropic hormone) in both ventricular CSF and blood plasma was carried out in 101 neurosurgical patients. The following results were obtained: I) beta-END and beta-LPH levels were found to be lower in the CSF than in blood plasma. II) beta-END and beta-LPH in the CSF was the same in both sexes. III) beta-END levels in the CSF decreased with age. IV) beta-END and beta-LPH levels showed a diurnal rhythm with a maximum in the late a. m. hours. V) beta-END levels in the ventricular CSF tend to decrease parallel to a drop in conciousness as well as with longlasting comatous states. VI) beta-END in ventricular CSF becomes higher with increasing systolic arterial blood pressure. VII) beta-END and beta-LPH levels in ventricular CSF are not correlated with the type of the disease, CSF pressure, body temperature or respiratory changes.

  7. Stem Cell Mobilization with G-CSF versus Cyclophosphamide plus G-CSF in Mexican Children

    José Eugenio Vázquez Meraz


    Full Text Available Fifty-six aphaereses were performed in 23 pediatric patients with malignant hematological and solid tumors, following three different protocols for PBPC mobilization and distributed as follows: A: seventeen mobilized with 4 g/m2 of cyclophosphamide (CFA and 10 μg/kg/day of granulocyte colony stimulating factor (G-CSF, B: nineteen with CFA + G-CSF, and C: twenty only with G-CSF when the WBC count exceeded 10 × 109/L. The average number of MNC/kg body weight (BW/aphaeresis was 0.4 × 108 (0.1–1.4, 2.25 × 108 (0.56–6.28, and 1.02 × 108 (0.34–2.5 whereas the average number of CD34+ cells/kg BW/aphaeresis was 0.18 × 106/kg (0.09–0.34, 1.04 × 106 (0.19–9.3, and 0.59 × 106 (0.17–0.87 and the count of CFU/kg BW/aphaeresis was 1.11 × 105 (0.31–2.12, 1.16 × 105 (0.64–2.97, and 1.12 × 105 (0.3–6.63 in groups A, B, and C, respectively. The collection was better in group B versus group A (p=0.007 and p=0.05, resp. and in group C versus group A (p=0.08 and p=0.05, resp.. The collection of PBPCs was more effective in the group mobilized with CFM + G-CSF when the WBC exceeded 10 × 103/μL in terms of MNC and CD34+ cells and there was no toxicity of the chemotherapy.



    objective: To recombinant the nearly natural humangranulocyte-macrophage-colony stimulating factor (GM-CSF) for supplying more safe and steady expressed cytokine in clinic. Method: The eukaryotic recombinant pcDNA3.1-GM-CSF plasmid which was controlled by the CMV promoter was transferred into CHO cell by lipofectamine, selected by G418 and the positive clones was got. The recombinant vector which was rejoined into the groups of DNA of CHO was identified by PCR. Results: The results showed that the protein of rhGM-CSF was about 28 KD by using ELISA, SDS-PAGE and Western blot. Conclusion: rhGM-CSF was expressed steadily and highly. The rhGM-CSF will be of more use value.

  9. Variability of CSF Alzheimer's disease biomarkers: implications for clinical practice.

    Stephanie J B Vos

    Full Text Available BACKGROUND: Cerebrospinal fluid (CSF biomarkers are increasingly being used for diagnosis of Alzheimer's disease (AD. OBJECTIVE: We investigated the influence of CSF intralaboratory and interlaboratory variability on diagnostic CSF-based AD classification of subjects and identified causes of this variation. METHODS: We measured CSF amyloid-β (Aβ 1-42, total tau (t-tau, and phosphorylated tau (p-tau by INNOTEST enzyme-linked-immunosorbent assays (ELISA in a memory clinic population (n = 126. Samples were measured twice in a single or two laboratories that served as reference labs for CSF analyses in the Netherlands. Predefined cut-offs were used to classify CSF biomarkers as normal or abnormal/AD pattern. RESULTS: CSF intralaboratory variability was higher for Aβ1-42 than for t-tau and p-tau. Reanalysis led to a change in biomarker classification (normal vs. abnormal of 26% of the subjects based on Aβ1-42, 10% based on t-tau, and 29% based on p-tau. The changes in absolute biomarker concentrations were paralleled by a similar change in levels of internal control samples between different assay lots. CSF interlaboratory variability was higher for p-tau than for Aβ1-42 and t-tau, and reanalysis led to a change in biomarker classification of 12% of the subjects based on Aβ1-42, 1% based on t-tau, and 22% based on p-tau. CONCLUSIONS: Intralaboratory and interlaboratory CSF variability frequently led to change in diagnostic CSF-based AD classification for Aβ1-42 and p-tau. Lot-to-lot variation was a major cause of intralaboratory variability. This will have implications for the use of these biomarkers in clinical practice.

  10. Low CSF oxytocin reflects high intent in suicide attempters.

    Jokinen, Jussi; Chatzittofis, Andreas; Hellström, Christer; Nordström, Peter; Uvnäs-Moberg, Kerstin; Asberg, Marie


    Data from animal studies suggest that oxytocin is an important modulating neuropeptide in regulation of social interaction. One human study has reported a negative correlation between CSF oxytocin levels, life history of aggression and suicidal behaviour. We hypothesized that CSF oxytocin levels would be related to suicidal behaviour, suicide intent, lifetime interpersonal violence and suicide risk. 28 medication free suicide attempters and 19 healthy volunteers participated in this cross sectional and longitudinal study. CSF and plasma morning basal levels of oxytocin were assessed with specific radio-immunoassays. The Beck Suicide Intent Scale (SIS), the Freeman scale and the Karolinska Interpersonal Violence Scale (KIVS) were used to assess suicide intent and lifetime violent behaviour. All patients were followed up for cause of death. The mean follow-up was 21 years. Suicide attempters had lower CSF oxytocin levels compared to healthy volunteers p=0.077. In suicide attempters CSF oxytocin showed a significant negative correlation with the planning subscale of SIS. CSF oxytocin showed a significant negative correlation with suicide intent, the planning subscale of SIS and Freeman interruption probability in male suicide attempters. Correlations between plasma oxytocin levels and the planning subscale of SIS and Freeman interruption probability were significant in male suicide attempters. Lifetime violent behaviour showed a trend to negative correlation with CSF oxytocin. In the regression analysis suicide intent remained a significant predictor of CSF oxytocin corrected for age and gender whereas lifetime violent behaviour showed a trend to be a predictor of CSF oxytocin. Oxytocin levels did not differ significantly in suicide victims compared to survivors. CSF oxytocin may be an important modulator of suicide intent and interpersonal violence in suicide attempters.

  13. BOOK REVIEW - International Law and Child Soldiers by Gus Waschefort

    Robbie Robinson


    Full Text Available Long gone are the days that the law pertaining to children essentially dealt with the position of children within the parent-child relationship. On the contrary it has become a highly specialised legal discipline in which international and regional conventions progressively establish norms and standards to be adhered to. This book by Waschefort, the 53rd volume in the series Studies in International Law, bears ample testimony to this. It reviews all of the international instruments containing proscriptive norms to prohibit the use and recruitment of child soldiers. It commences with an analysis of the current state of child soldiering internationally, after which relevant international instruments are comprehensively discussed with a clear focus on the question of whether or not the prohibitive norms are optimally enforced – are they capable of better enforcement? The author adopts an “issues-based approach” in terms of which no specific regime of law, for instance International Humanitarian Law, is considered dominant. He assesses universal and regional human rights law together with International Human Rights Law and International Criminal Law to establish a mutually reinforcing web of protection for children. He also critically assesses the international judicial, quasi-judicial and non-judicial entities most relevant to child soldier prevention. He argues that the effective implementation of child soldier prohibitive norms does not require fundamental changes to any entity or functionary engaged in such prevention. In fact, what is required according to the author is the constant reassessment and refinement of all such entities and functionaries. The conclusions which are reached are ultimately tested against the background of a comprehensive case study on the use and recruitment of child soldiers in the Democratic Republic of the Congo. International Law and Child Soldiers is to be welcomed as a timely contribution to the evaluation

  16. [Child Soldiers as Refugees in Germany].

    Zito, Dima


    Child Soldiers as Refugees in Germany How do former child soldiers cope with their potentially traumatic experiences, and how do the living conditions as refugees influence these coping processes? A dissertation at the faculty of human and social sciences at the University of Wuppertal, based on biographical-narrative interviews with 15 young refugees from six African countries, describes the characteristics of the traumatic sequences in the countries of origin and in exile, and elaborates typical coping processes. In order to survive a situation of absolute subjection within armed groups, children develop forms of adequate adaptation to the context like regulation and detachment of emotions e.g. with the use of drugs, assimilation to an idea of "hard masculinity" etc. They become victims, witnesses and often perpetrators of extreme violence (man-made-disaster), respectively traumatic processes can be seen in all sequences. After leaving the armed groups there is no way back into the families and communities destroyed by armed conflict, so they become refugees. In Germany, they are subjected to a bureaucratic and excluding asylum system, in which decisions on all relevant areas of life (age determination, place and right of residence, form of accommodation, access to education, etc.) are imposed on them. Especially the insecure right of residence and the living conditions in refugee camps are severe risk factors, impeding stabilization. Social support, e. g. by competent professionals, access to trauma- and culture-sensitive psychotherapy, societal inclusion, but also personal resilience are essential for coping with trauma and developing new future perspectives.

  17. CSF cortisol in Alzheimer's disease and mild cognitive impairment.

    Popp, Julius; Schaper, Karsten; Kölsch, Heike; Cvetanovska, Gabriela; Rommel, Fatima; Klingmüller, Dietrich; Dodel, Richard; Wüllner, Ullrich; Jessen, Frank


    Hypercortisolaemia occurs in Alzheimer's disease (AD) and may be involved in the AD related neurodegenerative process. In order to determine whether brain structures are exposed to high cortisol concentrations early in AD, we measured cerebrospinal fluid (CSF) cortisol in 66 subjects with AD, 33 subjects with mild cognitive impairment (MCI) and 34 control subjects. CSF cortisol concentrations were higher in AD subjects compared to controls (pcortisol in MCI subjects compared with controls suggesting that the increase of CSF cortisol is not an early event in the course of AD.

  6. Cognitive fitness.

    Gilkey, Roderick; Kilts, Clint


    Recent neuroscientific research shows that the health of your brain isn't, as experts once thought, just the product of childhood experiences and genetics; it reflects your adult choices and experiences as well. Professors Gilkey and Kilts of Emory University's medical and business schools explain how you can strengthen your brain's anatomy, neural networks, and cognitive abilities, and prevent functions such as memory from deteriorating as you age. The brain's alertness is the result of what the authors call cognitive fitness -a state of optimized ability to reason, remember, learn, plan, and adapt. Certain attitudes, lifestyle choices, and exercises enhance cognitive fitness. Mental workouts are the key. Brain-imaging studies indicate that acquiring expertise in areas as diverse as playing a cello, juggling, speaking a foreign language, and driving a taxicab expands your neural systems and makes them more communicative. In other words, you can alter the physical makeup of your brain by learning new skills. The more cognitively fit you are, the better equipped you are to make decisions, solve problems, and deal with stress and change. Cognitive fitness will help you be more open to new ideas and alternative perspectives. It will give you the capacity to change your behavior and realize your goals. You can delay senescence for years and even enjoy a second career. Drawing from the rapidly expanding body of neuroscience research as well as from well-established research in psychology and other mental health fields, the authors have identified four steps you can take to become cognitively fit: understand how experience makes the brain grow, work hard at play, search for patterns, and seek novelty and innovation. Together these steps capture some of the key opportunities for maintaining an engaged, creative brain.

  7. Armor and anesthesia: exposure, feeling, and the soldier's body.

    MacLeish, Kenneth T


    For many civilians, the high-tech weapons, armor, and military medicine with which U.S. soldiers are equipped present an image of lethal capacity and physical invulnerability. But, as this article explores, soldiers themselves just as often associate the life-sustaining technology of modern warfare with feelings that range from a pragmatic ambivalence about exposure to harm all the way to profoundly unsettling vulnerability. This article, based on fieldwork among soldiers and military families at the U.S. Army's Ft. Hood, examines sensory and affective dimensions of soldiers' intimate bodily relationships with the technologies that alternately or even simultaneously keep them alive and expose them to harm. I argue that modern military discipline and technology conspire to cultivate soldiers as highly durable, capable, unfeeling, interchangeable bodies, or what might be called, after Susan Buck-Morss (1992), anesthetic subjects. But for soldiers themselves, their training, combat environment, protective gear, and weapons are a rich font of both emotional and bodily feeling that exists in complex tension with the also deeply felt military imperative to carry on in the face of extreme discomfort and danger.

  8. The invisible soldiers: understanding how the life experiences of girl child soldiers impacts upon their health and rehabilitation needs.

    Stevens, Amy Jane


    There are estimated 120,000 girl child soldiers worldwide. Recruitment makes girls vulnerable to the violence of war, torture, psychological trauma and sexual abuse with huge impact on their physical, mental and reproductive health. Despite this, girl soldiers often remain an invisible and marginalised group frequently neglected from disarmament, demobilisation and reintegration programmes. This is not just a local issue: with former child soldiers seeking asylum as refugees there is an increasing need for health workers in the destination countries to understand their health needs in order to inform appropriate holistic service provision. This review provides an overview of how the duties and life experiences of girl soldiers, including gender-specific abuses, impacts upon their health and concludes with a summary of recommendations as to how their rehabilitation needs can be addressed.

    Full Text Available CSF ascites is a very rare complication of ventriculoperitoneal (VP shunt procedure. No definite explanation has been offered for the inability of the peritoneum to absorb the CSF. Two children who underwent VP shunting for hydrocephalus, presented with ascites 3 (1/2 years and 4 months respectively, after the shunt was placed. The treatment of choice is conversion of the VP shunt to a ventriculoatrial shunt.

    Menke, Ricarda A L; Gray, Elizabeth; Lu, Ching-Hua; Kuhle, Jens; Talbot, Kevin; Malaspina, Andrea; Turner, Martin R


    Objective Diffusion tensor imaging (DTI) is sensitive to white matter tract pathology. A core signature involving the corticospinal tracts (CSTs) has been identified in amyotrophic lateral sclerosis (ALS). Raised neurofilament light chain protein (NfL) in cerebrospinal fluid (CSF) is thought to reflect axonal damage in a range of neurological disorders. The relationship between these two measures was explored. Methods CSF and serum NfL concentrations and DTI acquired at 3 Tesla on the same day were obtained from ALS patients (n = 25 CSF, 40 serum) and healthy, age-similar controls (n = 17 CSF, 25 serum). Within-group correlations between NfL and DTI measures of microstructural integrity in major white matter tracts (CSTs, superior longitudinal fasciculi [SLF], and corpus callosum) were performed using tract-based spatial statistics. Results NfL levels were higher in patients compared to controls. CSF levels correlated with clinical upper motor neuron burden and rate of disease progression. Higher NfL levels were significantly associated with lower DTI fractional anisotropy and increased radial diffusivity in the CSTs of ALS patients, but not in controls. Interpretation Elevated CSF and serum NfL is, in part, a result of CST degeneration in ALS. This highlights the wider potential for combining neurochemical and neuroimaging-based biomarkers in neurological disease. PMID:26273687

    Full Text Available Since adaptive immunity is thought to be central to immunity against influenza A virus (IAV pneumonias, preventive strategies have focused primarily on vaccines. However, vaccine efficacy has been variable, in part because of antigenic shift and drift in circulating influenza viruses. Recent studies have highlighted the importance of innate immunity in protecting against influenza.Granulocyte-macrophage colony stimulating factor (GM-CSF contributes to maturation of mononuclear phagocytes, enhancing their capacity for phagocytosis and cytokine production.Overexpression of granulocyte macrophage-colony stimulating factor (GM-CSF in the lung of transgenic mice provides remarkable protection against IAV, which depends on alveolar macrophages (AM. In this study, we report that pulmonary delivery of GM-CSF to wild type young and aged mice abrogated mortality from IAV.We also demonstrate that protection is species specific and human GM-CSF do not protect the mice nor stimulates mouse immunity. We also show that IAV-induced lung injury is the culprit for side-effects of GM-CSF in treating mice after IAV infection, and introduce a novel strategy to deliver the GM-CSF to and retain it in the alveolar space even after IAV infection.

  16. Effect of CSF Suppression for Diffusional Kurtosis Imaging

    Yang, Alicia W.; Jensen, Jens H.; Hu, Caixia C.; Tabesh, Ali; Falangola, Maria F.; Helpern, Joseph A.


    Purpose To evaluate the cerebrospinal fluid (CSF) partial volume effect on diffusional kurtosis imaging (DKI) metrics in white matter and cortical gray matter. Materials and Methods Four healthy volunteers participated in this study. Standard DKI and fluid-attenuated inversion recovery (FLAIR) DKI experiments were performed using a twice-refocused-spin-echo diffusion sequence. The conventional diffusional tensor imaging (DTI) metrics of fractional anisotropy (FA), mean, axial, and radial diffusivity (MD, D∥, D⊥) together with DKI metrics of mean, axial and radial kurtosis (MK, K∥, K⊥) were measured and compared. Single image slices located above the lateral ventricles, with similar anatomical features for each subject, were selected to minimize the effect of CSF from the ventricles. Results In white matter, differences of less than 10% were observed between diffusion metrics measured with standard DKI and FLAIR-DKI sequences, suggesting minimal CSF contamination. For gray matter, conventional DTI metrics differed by 19% to 52%, reflecting significant CSF partial volume effect. Kurtosis metrics, however, changed by 11% or less, indicating greater robustness with respect to CSF contamination. Conclusion Kurtosis metrics are less sensitive to CSF partial voluming in cortical gray matter than conventional diffusion metrics. The kurtosis metrics may then be more specific indicators of changes in tissue microstructure, provided the effect sizes for the changes are comparable. PMID:23034866

  19. Elevated CSF outflow resistance associated with impaired lymphatic CSF absorption in a rat model of kaolin-induced communicating hydrocephalus

    Li Jie


    Full Text Available Abstract Background We recently reported a lymphatic cerebrospinal fluid (CSF absorption deficit in a kaolin model of communicating hydrocephalus in rats with ventricular expansion correlating negatively with the magnitude of the impediment to lymphatic function. However, it is possible that CSF drainage was not significantly altered if absorption at other sites compensated for the lymphatic defect. The purpose of this study was to investigate the impact of the lymphatic absorption deficit on global CSF absorption (CSF outflow resistance. Methods Kaolin was injected into the basal cisterns of Sprague Dawley rats. The development of hydrocephalus was assessed using magnetic resonance imaging (MRI. In one group of animals at about 3 weeks after injection, the movement of intraventricularly injected iodinated human serum albumin (125I-HSA into the olfactory turbinates provided an estimate of CSF transport through the cribriform plate into nasal lymphatics (n = 18. Control animals received saline in place of kaolin (n = 10. In a second group at about 3.5 weeks after kaolin injection, intraventricular pressure was measured continuously during infusion of saline into the spinal subarachnoid space at various flow rates (n = 9. CSF outflow resistance was calculated as the slope of the steady-state pressure versus flow rate. Control animals for this group either received no injections (intact: n = 11 or received saline in place of kaolin (n = 8. Results Compared to saline injected controls, lateral ventricular volume in the kaolin group was significantly greater (0.087 ± 0.013 ml, n = 27 versus 0.015 ± 0.001 ml, n = 17 and lymphatic function was significantly less (2.14 ± 0.72% injected/g, n = 18 versus 6.38 ± 0.60% injected/g, n = 10. Additionally, the CSF outflow resistance was significantly greater in the kaolin group (0.46 ± 0.04 cm H2O.μL-1.min, n = 9 than in saline injected (0.28 ± 0.03 cm H2O.μL-1.min, n = 8 or intact animals (0.18 ± 0

  20. Upfront plerixafor plus G-CSF versus cyclophosphamide plus G-CSF for stem cell mobilization in multiple myeloma: efficacy and cost analysis study.

    Afifi, S; Adel, N G; Devlin, S; Duck, E; Vanak, J; Landau, H; Chung, D J; Lendvai, N; Lesokhin, A; Korde, N; Reich, L; Landgren, O; Giralt, S; Hassoun, H


    Cyclophosphamide plus G-CSF (C+G-CSF) is one of the most widely used stem cell (SC) mobilization regimens for patients with multiple myeloma (MM). Plerixafor plus G-CSF (P+G-CSF) has demonstrated superior SC mobilization efficacy when compared with G-CSF alone and has been shown to rescue patients who fail mobilization with G-CSF or C+G-CSF. Despite the proven efficacy of P+G-CSF in upfront SC mobilization, its use has been limited, mostly due to concerns of high price of the drug. However, a comprehensive comparison of the efficacy and cost effectiveness of SC mobilization using C+G-CSF versus P+G-CSF is not available. In this study, we compared 111 patients receiving C+G-CSF to 112 patients receiving P+G-CSF. The use of P+G-CSF was associated with a higher success rate of SC collection defined as ⩾5 × 10(6) CD34+ cells/kg (94 versus 83%, P=0.013) and less toxicities. Thirteen patients in the C+G-CSF arm were hospitalized owing to complications while none in the P+G-CSF group. C+G-CSF was associated with higher financial burden as assessed using institutional-specific costs and charges (P<0.001) as well as using Medicare reimbursement rates (P=0.27). Higher rate of hospitalization, increased need for salvage mobilization, and increased G-CSF use account for these differences.

  1. Caffeine use among active duty US Army soldiers.

    Lieberman, Harris R; Stavinoha, Trisha; McGraw, Susan; White, Alan; Hadden, Louise; Marriott, Bernadette P


    Eighty-percent of the US adult population regularly consumes caffeine, but limited information is available on the extent and patterns of use. Caffeine use is a public health issue and its risks and benefits are regularly considered in scientific literature and the lay media. Recently, new caffeine-containing products have been introduced and are widely available on Army bases and are added to rations to maintain cognitive performance. This study surveyed caffeine consumption and demographic characteristics in 990 US Army soldiers. Data were weighted by age, sex, rank, and Special Forces status. Total caffeine intake and intake from specific products were estimated. Logistic regression was used to examine relationships between caffeine use and soldier demographic and lifestyle characteristics. Eighty-two percent of soldiers consumed caffeine at least once a week. Mean daily caffeine consumption was 285 mg/day (347 mg/day among regular caffeine consumers). Male soldiers consumed, on average, 303 mg/day and females 163 mg/day (regular consumers: 365 mg/day for male soldiers, 216 mg/day for female soldiers). Coffee was the main source of caffeine intake. Among young males, energy drinks were the largest source of caffeine intake, but their intake was not greater than older males. Regression analysis indicated an association of higher caffeine intake with male sex, white race, and tobacco use (P<0.01). Most soldiers consume caffeine in levels accepted as safe, but some consume greater quantities than recommended, although definitive information on safe upper limits of caffeine intake is not available. Labels of caffeine-containing products should provide caffeine content so individuals can make informed decisions.

  2. Review of physiotherapy records to characterise musculoskeletal injury in Australian soldiers in the 16th Air Defence Regiment

    Rolf Sellentin


    source of the dependence was investigated by analysis of standardised residuals for each cell. Results: Five predominant types or areas of injury sustained by Australian soldiers of the 16th Air Defence Regiment were identified to be neck, low back, ankle, patella and knee ligament. The frequency of low back injuries was found to be significantly higher than the other types of injury (chi-square goodness of fit test, p < 0.001, then analysis of standardised residuals with Bonferroni adjustment. There was insufficient evidence of a relationship between type of injury and subunit (chi-square test of independence, p = 0.33. Five predominant causes of musculoskeletal injury were identified to be biomechanical, work, running, sports and physical training. Evidence of a relationship between type of injury and cause was found to be statistically significant (chi-square test of independence, p < 0.001 in the cause ‘sports’, which is associated with a relatively higher frequency of ankle inversion injuries, and ‘running’, which is associated with a relatively higher frequency of patella-femoral joint injuries (p < 0.002. Conclusion: This is the first full review of data on musculoskeletal injuries sustained by Australian soldiers of the 16th Air Defence Regiment. Types of musculoskeletal injuries and causes were analysed and patterns of injury were identified. Measures can now be drawn up with the aim of injury prevention.

  4. Post craniotomy extra-ventricular drain (EVD) associated nosocomial meningitis: CSF diagnostic criteria.

    Muñoz-Gómez, Sigridh; Wirkowski, Elizabeth; Cunha, Burke A


    Because external ventricular drains (EVDs) provide access to cerebrospinal fluid (CSF), there is potential for EVD associated acute bacterial meningitis (EVD-AM). Post-craniotomy, in patients with EVDs, one or more CSF abnormalities are commonly present making the diagnosis of EVD-AM problematic. EVD-AM was defined as elevated CSF lactic acid (>6 nmol/L), plus CSF marked pleocytosis (>50 WBCs/mm(3)), plus a positive Gram stain (same morphology as CSF isolate), plus a positive CSF culture of neuropathogen (same morphology as Gram stained organism). We reviewed 22 adults with EVDs to determine if our four CSF parameters combined accurately identified EVD-AM. No single or combination of <4 CSF parameters correctly diagnosed or ruled out EVD-AM. Combined our four CSF parameters clearly differentiated EVD-AM from one case of pseudomeningitis due to E. cloacae. We conclude that our four CSF criteria combined are useful in diagnosing EVD-AM in adults.

    Full Text Available In order to attract more promising young people to join the military and enhance combat capability, Taiwan’s Department of Defense is transforming the nation’s military service system from a draft system, which has been in effect for more than sixty years, to an all-volunteer military force system. The government hopes that the new system not only can recruit promising voluntary soldiers, but that they also continue their military service after the contract expires in order to ensure stability in recruitment sources. This study explores the intention of voluntary soldiers to continue their military service. This study’s questionnaire encompasses five dimensions: Participation motivation, organization commitment, career planning, personality traits and departure tendency. The questionnaires were issued to 350 voluntary soldiers to explore if they intend to continue their service after their contract expires, with a total of 314 effective questionnaires that were recovered and analyzed. The results find that about half of the voluntary soldiers indicate that they do not plan on staying and continuing their service after contract expiration, which will result in understaffing in the military. In order to stabilize the prescribed number of soldiers, the existing recruiting policy and military management system should be re-adjusted.

  9. Plasmin system of Alzheimer's disease patients: CSF analysis.

    Martorana, Alessandro; Sancesario, Giulia M; Esposito, Zaira; Nuccetelli, Marzia; Sorge, Roberto; Formosa, Amanda; Dinallo, Vincenzo; Bernardi, Giorgio; Bernardini, Sergio; Sancesario, Giuseppe


    Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder characterized by the extracellular deposit of Amyloid beta (Aβ), mainly of the Amyloid beta(1-42) (Aβ(1-42)) peptide in the hippocampus and neocortex leading to progressive cognitive decline and dementia. The possible imbalance between the Aβ production/degradation process was suggested to contribute to the pathogenesis of AD. Among others, the serine protease plasmin has shown to be involved in Aβ(1-42) clearance, a hypothesis strengthened by neuropathological studies on AD brains. To explore whether there is a change in plasmin system in CSF of AD patients, we analyzed CSF samples from AD and age-matched controls, looking at plasminogen, tissue plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) protein levels and t-PA and urokinase plasminogen activator (u-PA) enzymatic activities. We also measured Aβ(1-42), total-tau and phospho-tau (181) CSF levels and sought for a possible relationship between them and plasmin system values. Our findings showed that t-PA, plasminogen and PAI-1 levels, as t-PA enzymatic activity, remained unchanged in AD with respect to controls; u-PA activity was not detected. We conclude that CSF analysis of plasminogen system does not reflect changes observed post-mortem. Unfortunately, the CSF detection of plasmin system could not be a useful biomarker for either AD diagnosis or disease progression. However, these findings do not exclude the possible involvement of the plasmin system in AD.

  10. GM-CSF alters dendritic cells in autoimmune diseases.

    Li, Bao-Zhu; Ye, Qian-Ling; Xu, Wang-Dong; Li, Jie-Hua; Ye, Dong-Qing; Xu, Yuekang


    Autoimmune diseases arise from an inappropriate immune response against self components, including macromolecules, cells, tissues, organs etc. They are often triggered or accompanied by inflammation, during which the levels of granulocyte macrophage colony-stimulating factor (GM-CSF) are elevated. GM-CSF is an inflammatory cytokine that has profound impact on the differentiation of immune system cells of myeloid lineage, especially dendritic cells (DCs) that play critical roles in immune initiation and tolerance, and is involved in the pathogenesis of autoimmune diseases. Although GM-CSF was discovered decades ago, recent studies with some new findings have shed an interesting light on the old hematopoietic growth factor. In the inflammatory autoimmune diseases, GM-CSF redirects the normal developmental pathway of DCs, conditions their antigen presentation capacities and endows them with unique cytokine signatures to affect autoimmune responses. Here we review the latest advances in the field, with the aim of demonstrating the effects of GM-CSF on DCs and their influences on autoimmune diseases. The summarized knowledge will help to design DC-based strategies for the treatment of autoimmune diseases.

  11. CSF biomarkers cutoffs: the importance of coincident neuropathological diseases.

    Toledo, Jon B; Brettschneider, Johannes; Grossman, Murray; Arnold, Steven E; Hu, William T; Xie, Sharon X; Lee, Virginia M-Y; Shaw, Leslie M; Trojanowski, John Q


    The effects of applying clinical versus neuropathological diagnosis and the inclusion of cases with coincident neuropathological diagnoses have not been assessed specifically when studying cerebrospinal fluid (CSF) biomarker classification cutoffs for patients with neurodegenerative diseases that cause dementia. Thus, 142 neuropathologically diagnosed neurodegenerative dementia patients [71 Alzheimer's disease (AD), 29 frontotemporal lobar degeneration (FTLD), 3 amyotrophic lateral sclerosis, 7 dementia with Lewy bodies, 32 of which cases also had coincident diagnoses] were studied. 96 % had enzyme-linked immunosorbant assay (ELISA) CSF data and 77 % had Luminex CSF data, with 43 and 46 controls for comparison, respectively. Aβ(42), total, and phosphorylated tau(181) were measured. Clinical and neuropathological diagnoses showed an 81.4 % overall agreement. Both assays showed high sensitivity and specificity to classify AD subjects against FTLD subjects and controls, and moderate sensitivity and specificity for classifying FTLD subjects against controls. However, among the cases with neuropathological diagnoses of AD plus another pathology (26.8 % of the sample), 69.4 % (ELISA) and 96.4 % (Luminex) were classified as AD according to their biomarker profiles. Use of clinical diagnosis instead of neuropathological diagnosis led to a 14-17 % underestimation of the biomarker accuracy. These results show that while CSF Aβ and tau assays are useful for diagnosis of AD and neurodegenerative diseases even at MCI stages, CSF diagnostic analyte panels that establish a positive diagnosis of Lewy body disease and FTLD are also needed, and must be established based on neuropathological rather than clinical diagnoses.

  12. Beyond child soldiering: the interference of daily living conditions in former child soldiers' longer term psychosocial well-being in northern Uganda.

    Vindevogel, Sofie; Coppens, Kathleen; De Schryver, Maarten; Loots, Gerrit; Broekaert, Eric; Derluyn, Ilse


    Given the various developments in former child soldiers' psychosocial well-being over time, the question arises as to which factors are associated with the prevalence of psychological distress. An ongoing debate points to the plausible importance of child soldiering-related and post-child soldiering factors. This study is an exploratory analysis of both types of association with former child soldiers' psychosocial well-being in the longer term. Follow-up data on a convenience sample of 424 northern Ugandan former child soldiers are analysed. Psychological symptoms are assessed by a review of the intake and assessment forms of the Rachele Rehabilitation Centre, which were not validated and did not include a standardised translation into the local language. These psychological symptoms and possible associated factors are analysed using binary logistic regression analysis. Thereby, both child soldiering-related and post-child soldiering variables are accounted for. The outcomes reveal almost no significant main effects of child soldiering-related variables, while a range of post-child soldiering variables (number of meals a day, school attendance, insults and professional support) are clearly associated with the prevalence of the measured psychological symptoms in the longer term. These exploratory conclusions should be further investigated in representative samples of former child soldiers using validated assessment tools.

    We used administrative data to examine predictors of medically documented suicide ideation (SI) among Regular Army soldiers from 2006 through 2009 (N = 10,466 ideators, 124,959 control person-months). Enlisted ideators (97.8% of all cases) were more likely than controls to be female, younger, older when entering service, less educated, never or previously deployed, and have a recent mental health diagnosis. Officer ideators were more likely than controls to be female, younger, younger when entering service, never married, and have a recent mental health diagnosis. Risk among enlisted soldiers peaked in the second month of service and declined steadily, whereas risk among officers remained relatively stable over time. Risk of SI is highest among enlisted soldiers early in Army service, females, and those with a recent mental health diagnosis.

    Substantial attention and resources are aimed at the reintegration of child soldiers, yet rigorous evaluations are rare. This tracer study was conducted among former child soldiers (N=452) and never-recruited peers (N=191) who participated in an economic support program in Burundi. Socio-economic outcome indicators were measured retrospectively for the period before receiving support (T1; 2005-06); immediately afterwards (T2; 2006-07); and at present (T3; 2010). Participants also rated present functional impairment and mental health indicators. Participants reported improvement on all indicators, especially economic opportunity and social integration. At present no difference existed between both groups on any of the outcome indicators. Socio-economic functioning was negatively related with depression- and, health complaints and positively with intervention satisfaction. The present study demonstrates promising reintegration trajectories of former child soldiers after participating in a support program.

  1. Multiple trauma and mental health in former Ugandan child soldiers.

    Klasen, Fionna; Oettingen, Gabriele; Daniels, Judith; Adam, Hubertus


    The present study examines the effect of war and domestic violence on the mental health of child soldiers in a sample consisting of 330 former Ugandan child soldiers (age: 11-17 years, female: 49%). All children had experienced at least 1 war-related event and 78% were additionally exposed to at least 1 incident of domestic violence. Prevalences of posttraumatic stress disorder and major depressive disorder were 33%, and 36%, respectively. Behavioral and emotional problems above clinical cutoff were measured in 61%. No gender differences were found regarding mental health outcomes. War experience and domestic violence were significantly associated with all mental health outcomes. The authors' findings point to the detrimental effects of domestic violence in addition to traumatizing war experiences in child soldiers.

  5. Exoskeleton for Soldier Enhancement Systems Feasibility Study

    Jansen, J.F.


    The development of a successful exoskeleton for human performance augmentation (EHPA) will require a multi-disciplinary systems approach based upon sound biomechanics, power generation and actuation systems, controls technology, and operator interfaces. The ability to integrate key components into a system that enhances performance without impeding operator mobility is essential. The purpose of this study and report are to address the issue of feasibility of building a fieldable EHPA. Previous efforts, while demonstrating progress and enhancing knowledge, have not approached the level required for a fully functional, fieldable system. It is doubtless that the technologies required for a successful exoskeleton have advanced, and some of them significantly. The question to be addressed in this report is have they advanced to the point of making a system feasible in the next three to five years? In this study, the key technologies required to successfully build an exoskeleton have been examined. The primary focus has been on the key technologies of power sources, actuators, and controls. Power sources, including internal combustion engines, fuel cells, batteries, super capacitors, and hybrid sources have been investigated and compared with respect to the exoskeleton application. Both conventional and non-conventional actuator technologies that could impact EHPA have been assessed. In addition to the current state of the art of actuators, the potential for near-term improvements using non-conventional actuators has also been addressed. Controls strategies, and their implication to the design approach, and the exoskeleton to soldier interface have also been investigated. In addition to these key subsystems and technologies, this report addresses technical concepts and issues relating to an integrated design. A recommended approach, based on the results of the study is also presented.

  6. Echocardiographic findings in patients with spontaneous CSF leak.

    Pimienta, Allen L; Rimoin, David L; Pariani, Mitchel; Schievink, Wouter I; Reinstein, Eyal


    The presence of cardiovascular abnormalities in patients with spontaneous cerebrospinal fluid (CSF) leaks are not well-documented in the literature, as cardiovascular evaluation is not generally pursued if a patient does not exhibit additional clinical features suggesting an inherited connective tissue disorder. We aimed to assess this association, enrolling a consecutive group of 50 patients referred for spinal CSF leak consultation. Through echocardiographic evaluation and detailed medical history, we estimate that up to 20% of patients presenting with a spontaneous CSF leak may have some type of cardiovascular abnormality. Further, the increase in prevalence of aortic dilatation in our cohort was statistically significant in comparison to the estimated population prevalence. This supports a clinical basis for echocardiographic screening of these individuals for cardiovascular manifestations that may have otherwise gone unnoticed or evolved into a more severe manifestation.




    Full Text Available INTRODUCTION Acute infections of nervous system are among the most important problems in medicine because early recognition, efficient decision making and rapid institution of therapy can be lifesaving. Making a clinical diagnosis of acute meningitis depends on the cornerstone of cerebrospinal fluid (CSF examination. We present a case with the above-mentioned difficulty and the approach involved in establishing the exact diagnosis and institution of appropriate treatment. CONCLUSION About findings in viral meningitis one should be careful while evaluating a CSF report so as to not make a mistaken diagnosis and delay treatment. The most important analysis in patients whose symptoms are consistent with herpes simplex meningitis is the detection of Herpes simplex Virus deoxy-ribo-nucleic acid (HSV-DNA in CSF with Polymerase Chain Reaction (PCR.

  8. [Two cases of spontaneous cerebrospinal fluid (CSF) otorrhea with meningitis].

    Mada, Yusuke; Ueki, Yuji; Konno, Akiyoshi


    We report on two cases of spontaneous CSF otorrhea, which were considered to have been caused by enlarged arachnoid granulation with bone erosion of the posterior fossa. Both cases visited us complaining of severe headache, due to bacterial meningitis. In the first patient, a 68-year-old male, a high resolution CT scan showed a bony defect in the posterior fossa plate in the right temporal bone, where CSF leakage was confirmed during the operation. In the second patient, a 54-year-old female, a bony defect was located in the posterior fossa in the left temporal bone. In both cases, the bony defects were repaired by occlusion with the pedicled temporal muscles after the meningitis had been treated. CSF otorrhea disappeared after the surgery, and has not recurred during the postoperative observation period of 1 to 3 years.

  9. [Psychological impact on French soldiers in the Central African Republic].

    Le Pape, Erwan; de Montleau, Franck


    The many constraints and psychologically demanding situations to which French soldiers are subjected (living conditions, operational pace, scenes of exaction, hostile crowds, combat situations) have justified a psychiatrist being posted to the theatre of operation Sangaris, in the Central African Republic, soon after the military intervention began. While the psychiatrist's activity is typical of psychiatry in operational situations,.the configuration of the conflict- a civil war - and its impact on the psyche of the soldiers making up the task force have resulted in these practices being adapted and acknowledgement of the need to update skills.

    To improve clinical, neuropsychological and behavioural characterisation of the cerebrospinal fluid (CSF) biomarkers beta-amyloid((1-42)) protein (Abeta42), protein tau (tau) and tau phosphorylated at threonine 181 (P-tau181) across diagnostic dementia categories, a prospective study was set up. Patients with probable Alzheimer's disease (AD) (n=201), AD with cerebrovascular disease (CVD) (AD+CVD) (n=33), frontotemporal dementia (FTD) (n=27), dementia with Lewy bodies (DLB) (n=22) and healthy controls (n=148) were included. All patients underwent neuropsychological examination and behavioural assessment by means of a battery of behavioural assessment scales. CSF was obtained by lumbar puncture and levels of Abeta42, tau and P-tau181 were determined with commercially available ELISA kits. Negative correlations between CSF Abeta42 levels and aggressiveness (Spearman: r=-0.223; p=0.002) and positive correlations with age at inclusion (r=0.195; p=0.006), age at onset (r=0.205; p=0.003) and MMSE scores (r=0.198; p=0.005) were found in AD. In AD+CVD, CSF Abeta42 levels were correlated with MMSE (r=0.482; p=0.006), Hierarchic Dementia Scale (r=0.503; p=0.017) and Boston Naming Test (r=0.516; p=0.012) scores. In controls, age was positively correlated with CSF tau (r=0.465; pbiomarker levels were obtained in healthy controls compared to AD patients, indicating that AD-induced pathophysiological processes change age-dependent regulation of CSF biomarker levels.

  11. Big and tall soldiers are more likely to survive battle: a possible explanation for the 'returning soldier effect' on the secondary sex ratio.

    Kanazawa, Satoshi


    It is widely known that more boys are born during and immediately after wars, but there has not been any ultimate (evolutionary) explanation for this 'returning soldier effect'. Here, I suggest that the higher sex ratios during and immediately after wars might be a byproduct of the fact that taller soldiers are more likely to survive battle and that taller parents are more likely to have sons. I analyze a large sample of British Army service records during World War I. Surviving soldiers were on average more than one inch (3.33 cm) taller than fallen soldiers. Conservative estimates suggest that the one-inch height advantage alone is more than twice as sufficient to account for all the excess boys born in the UK during and after World War I. While it remains unclear why taller soldiers are more likely to survive battle, I predict that the returning soldier effect will not happen in more recent and future wars.

  14. CSF α-synuclein improves diagnostic and prognostic performance of CSF tau and Aβ in Alzheimer's disease.

    Toledo, Jon B; Korff, Ane; Shaw, Leslie M; Trojanowski, John Q; Zhang, Jing


    Alzheimer's disease (AD) and Lewy body diseases (LBD), e.g., Parkinson's disease (PD) dementia and dementia with Lewy bodies (DLB), are common causes of geriatric cognitive impairments. In addition, AD and LBD are often found in the same patients at autopsy; therefore, biomarkers that can detect the presence of both pathologies in living subjects are needed. In this investigation, we report the assessment of α-synuclein (α-syn) in cerebrospinal fluid (CSF) and its association with CSF total tau (t-tau), phosphorylated tau181 (p-tau181), and amyloid beta1-42 (Aβ1-42) in subjects of the Alzheimer's Disease Neuroimaging Initiative (ADNI; n = 389), with longitudinal clinical assessments. A strong correlation was noted between α-syn and t-tau in controls, as well as in patients with AD and mild cognitive impairment (MCI). However, the correlation is not specific to subjects in the ADNI cohort, as it was also seen in PD patients and controls enrolled in the Parkinson's Progression Markers Initiative (PPMI; n = 102). A bimodal distribution of CSF α-syn levels was observed in the ADNI cohort, with high levels of α-syn in the subjects with abnormally increased t-tau values. Although a correlation was also noted between α-syn and p-tau181, there was a mismatch (α-syn-p-tau181-Mis), i.e., higher p-tau181 levels accompanied by lower α-syn levels in a subset of ADNI patients. We hypothesize that this α-syn-p-tau181-Mis is a CSF signature of concomitant LBD pathology in AD patients. Hence, we suggest that inclusion of measures of CSF α-syn and calculation of α-syn-p-tau181-Mis improves the diagnostic sensitivity/specificity of classic CSF AD biomarkers and better predicts longitudinal cognitive changes.

    Macrophage colony-stimulating factor (M-CSF) has been proved to have a positive role in the follicular development. We investigated its effect on human granulosa cells and found that M-CSF could stimulate the production of E2. The production of FSH receptors was enhanced by M-CSF in vitro in a dose-dependent manner with or without the addition of tamoxifen (p M-CSF and its receptor (p M-CSF (p M-CSF has a role in regulating the response of granulosa cells to gonadotropins. Its function is associated with JAK/STAT-signaling pathway.

  19. Streamflow characteristics and trends along Soldier Creek, Northeast Kansas

    Juracek, Kyle E.


    Historical data for six selected U.S. Geological Survey streamgages along Soldier Creek in northeast Kansas were used in an assessment of streamflow characteristics and trends. This information is required by the Prairie Band Potawatomi Nation for the effective management of tribal water resources, including drought contingency planning. Streamflow data for the period of record at each streamgage were used to assess annual mean streamflow, annual mean base flow, mean monthly flow, annual peak flow, and annual minimum flow.Annual mean streamflows along Soldier Creek were characterized by substantial year-to-year variability with no pronounced long-term trends. On average, annual mean base flow accounted for about 20 percent of annual mean streamflow. Mean monthly flows followed a general seasonal pattern that included peak values in spring and low values in winter. Annual peak flows, which were characterized by considerable year-to-year variability, were most likely to occur in May and June and least likely to occur during November through February. With the exception of a weak yet statistically significant increasing trend at the Soldier Creek near Topeka, Kansas, streamgage, there were no pronounced long-term trends in annual peak flows. Annual 1-day, 30-day, and 90-day mean minimum flows were characterized by considerable year-to-year variability with no pronounced long-term trend. During an extreme drought, as was the case in the mid-1950s, there may be zero flow in Soldier Creek continuously for a period of one to several months.

A.; Naifeh, J. A.; Nock, M. K.; Sampson, N. A.; Schoenbaum, M.; Ursano, R. J.; Zaslavsky, A. M.; Kessler, R. C.


    Background The Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) has found that the proportional elevation in the US Army enlisted soldier suicide rate during deployment (compared with the never-deployed or previously deployed) is significantly higher among women than men, raising the possibility of gender differences in the adverse psychological effects of deployment. Method Person-month survival models based on a consolidated administrative database for active duty enlisted Regular Army soldiers in 2004–2009 (n = 975 057) were used to characterize the gender × deployment interaction predicting suicide. Four explanatory hypotheses were explored involving the proportion of females in each soldier’s occupation, the proportion of same-gender soldiers in each soldier’s unit, whether the soldier reported sexual assault victimization in the previous 12 months, and the soldier’s pre-deployment history of treated mental/behavioral disorders. Results The suicide rate of currently deployed women (14.0/100 000 person-years) was 3.1–3.5 times the rates of other (i.e. never-deployed/previously deployed) women. The suicide rate of currently deployed men (22.6/100 000 person-years) was 0.9–1.2 times the rates of other men. The adjusted (for time trends, sociodemographics, and Army career variables) female:male odds ratio comparing the suicide rates of currently deployed v. other women v. men was 2.8 (95% confidence interval 1.1–6.8), became 2.4 after excluding soldiers with Direct Combat Arms occupations, and remained elevated (in the range 1.9–2.8) after adjusting for the hypothesized explanatory variables. Conclusions These results are valuable in excluding otherwise plausible hypotheses for the elevated suicide rate of deployed women and point to the importance of expanding future research on the psychological challenges of deployment for women.

  20. Emerging Roles for CSF-1 Receptor and its Ligands in the Nervous System.

    Chitu, Violeta; Gokhan, Şölen; Nandi, Sayan; Mehler, Mark F; Stanley, E Richard


    The colony-stimulating factor-1 receptor (CSF-1R) kinase regulates tissue macrophage homeostasis, osteoclastogenesis, and Paneth cell development. However, recent studies in mice have revealed that CSF-1R signaling directly controls the development and maintenance of microglia, and cell autonomously regulates neuronal differentiation and survival. While the CSF-1R-cognate ligands, CSF-1 and interleukin-34 (IL-34) compete for binding to the CSF-1R, they are expressed in a largely non-overlapping manner by mature neurons. The recent identification of a dominantly inherited, adult-onset, progressive dementia associated with inactivating mutations in the CSF-1R highlights the importance of CSF-1R signaling in the brain. We review the roles of the CSF-1R and its ligands in microglial and neural development and function, and their relevance to our understanding of neurodegenerative disease.

  1. Meningitis and Meningoencephalitis among Israel Defense Force Soldiers: 20 Years Experience at the Hadassah Medical Centers.

    Pikkel, Yoav Y; Ben-Hur, Tamir; Eliahou, Ruth; Honig, Asaf


    Meningitis and meningoencephalitis pose major risks of morbidity and mortality. To describe 20 years of experience treating infections of the central nervous system in Israel Defense Force (IDF) soldiers, including the common presentations, pathogens and sequelae, and to identify risk groups among soldiers. All soldiers who were admitted to the Hadassah University Medical Center (both campuses: Ein Kerem and Mt. Scopus) due to meningitis and meningoencephalitis from January 1993 to January 2014 were included in this retrospective study. Clinical, laboratory and radiologic data were reviewed from their hospital and army medical corps files. Attention was given to patients' military job description, i.e., combat vs. non-combat soldier, soldiers in training, and medical personnel. We identified 97 cases of suspected meningitis or meningoencephalitis. Six were mistakenly filed and these patients were found to have other disorders. Four soldiers were diagnosed with epidural abscess and five with meningitis due to non-infectious in flammatory diseases. Eighty-two soldiers in active and reserve duty had infectious meningitis or meningoencephalitis. Of these, 46 (56.1%) were combat soldiers and 31 (37.8%) non-combat; 20 (29.2%) were soldiers in training, 10 (12.2%) were training staff and 8 (9.8%) were medical staff. The main pathogens were enteroviruses, Epstein-Barr virus an d Neisseria meningitidis. In our series, soldiers in training, combat soldiers and medical personnel had meningitis and meningoencephalitis more than other soldiers. Enteroviruses are highly infectious pathogens and can cause outbreaks. N. meningitidis among IDF soldiers is still a concern. Early and aggressive treatment with steroids should be considered especially in robust meningoencephalitis cases.

In vitro, G-CSF acts anti-apoptotically on motoneuronal cells. Due to the pleiotrophic effects of G-CSF and the complexity of the SOD1 transgenic ALS models it was however not possible to clearly distinguish between directly mediated anti-apoptotic and indirectly protective effects on motoneurons. Here we studied whether G-CSF is able to protect motoneurons from purely apoptotic cell death induced by a monocausal paradigm, neonatal sciatic nerve axotomy. Results We performed sciatic nerve axotomy in neonatal mice overexpressing G-CSF in the CNS and found that G-CSF transgenic mice displayed significantly higher numbers of surviving lumbar motoneurons 4 days following axotomy than their littermate controls. Also, surviving motoneurons in G-CSF overexpressing animals were larger, suggesting additional trophic effects of this growth factor. Conclusions In this model of pure apoptotic cell death the protective effects of G-CSF indicate direct actions of G-CSF on motoneurons in vivo. This shows that G-CSF exerts potent anti-apoptotic activities towards motoneurons in vivo and suggests that the protection offered by G-CSF in ALS mouse models is due to its direct neuroprotective activity.

  4. Fatal cerebral edema associated with serine deficiency in CSF.

    Keularts, Irene M L W; Leroy, Piet L J M; Rubio-Gozalbo, Estela M; Spaapen, Leo J M; Weber, Biene; Dorland, Bert; de Koning, Tom J; Verhoeven-Duif, Nanda M


    Two young girls without a notable medical history except for asthma presented with an acute toxic encephalopathy with very low serine concentrations both in plasma and cerebrospinal fluid (CSF) comparable to patients with 3-phosphoglycerate dehydrogenase (3-PGDH) deficiency. Clinical symptoms and enzyme measurement (in one patient) excluded 3-PGDH deficiency. Deficiencies in other serine biosynthesis enzymes were highly unlikely on clinical grounds. On basis of the fasting state, ketone bodies and lactate in plasma, urine and CSF, we speculate that reduced serine levels were due to its use as gluconeogenic substrate, conversion to pyruvate by brain serine racemase or decreased L-serine production because of a lack of glucose. These are the first strikingly similar cases of patients with a clear secondary serine deficiency associated with a toxic encephalopathy.

  5. Endoscopic endonasal multilayer repair of traumatic CSF rhinorrhea.

    Ibrahim, Ahmed Aly; Okasha, Mohamed; Elwany, Samy


    The incidence of traumatic CSF has increased in recent years due to increased incidence of road traffic accidents (RTA) as well the increasing number of endoscopic sinus surgeries (ESS). The objective of this study is to present our experience in management of traumatic CSF leaks using the endoscopic multilayer repair technique. Forty-two patients (aged 10-75 years, 30 males and 12 females) presenting with confirmed post-traumatic CSF rhinorrhea were operated upon between January 2007 and December 2013. The endoscopic multilayer technique was used in all cases. Electromagnetic navigation was used in some cases. All cases presented with intermittent watery rhinorrhea. The duration of the rhinorrhea ranged from 3 days to 1 year before repair. One case presented after 10 years from the causative trauma. Ten cases had a history of meningitis. Nine cases had more than one defect. Iatrogenic defects were larger than defects following accidental trauma. Two cases, following RTA, developed pseudo-aneurysm of internal carotid artery. Ten cases had associated pneumocephalus. The mean duration of postoperative hospitalization was 6 days (range 4-8 days). The mean follow-up duration was 31.2 +/- 11.4 months (range 16-48 months). None of our patient developed serious intra- or postoperative complications. Only one case required another surgery to repair a missed second defect. Post-traumatic CSF leaks can be successfully managed via the endonasal endoscopic route using the multilayer repair technique. It is important to look for multiple defects in these cases. CT angiography is recommended for traumatic leaks involving the lateral wall of the sphenoid sinus to diagnose or exclude the development of pseudo-aneurysm of the internal carotid artery.

  6. PET measurements of cerebral metabolism corrected for CSF contributions

    Chawluk, J.; Alavi, A.; Dann, R.; Kushner, M.J.; Hurtig, H.; Zimmerman, R.A.; Reivich, M.


    Thirty-three subjects have been studied with PET and anatomic imaging (proton-NMR and/or CT) in order to determine the effect of cerebral atrophy on calculations of metabolic rates. Subgroups of neurologic disease investigated include stroke, brain tumor, epilepsy, psychosis, and dementia. Anatomic images were digitized through a Vidicon camera and analyzed volumetrically. Relative areas for ventricles, sulci, and brain tissue were calculated. Preliminary analysis suggests that ventricular volumes as determined by NMR and CT are similar, while sulcal volumes are larger on NMR scans. Metabolic rates (18F-FDG) were calculated before and after correction for CSF spaces, with initial focus upon dementia and normal aging. Correction for atrophy led to a greater increase (%) in global metabolic rates in demented individuals (18.2 +- 5.3) compared to elderly controls (8.3 +- 3.0,p < .05). A trend towards significantly lower glucose metabolism in demented subjects before CSF correction was not seen following correction for atrophy. These data suggest that volumetric analysis of NMR images may more accurately reflect the degree of cerebral atrophy, since NMR does not suffer from beam hardening artifact due to bone-parenchyma juxtapositions. Furthermore, appropriate correction for CSF spaces should be employed if current resolution PET scanners are to accurately measure residual brain tissue metabolism in various pathological states.

  7. Neurocysticercosis: relationship between Taenia antigen levels in CSF and MRI

    Objective: to determine the relationship between Taenia antigen (TA) detection in cerebrospinal fluid (CSF) and magnetic resonance imaging (MRI) findings in patients with definite diagnosis of neurocysticercosis (NC). Method: sixty-three patients with definite diagnosis of NC were submitted to a MRI of the brain, and to a CSF examination, with a meticulous search for TA by ELISA. Results: TA detection was positive in 36 patients (57.1%). A total of 836 lesions were analyzed, greatly within the cerebral parenchyma (98.7 of the lesions). Intact or non-degenerating cysts were the most common evolutive phase observed (50.4% of all lesions), 22.1% were degenerating cysts and 19.5% calcified cysts. We observed a significant relationship between TA levels detected and the total number of lesions and the number of non-degenerating cysts, but not with calcified lesions. Conclusion: according to our results, we propose at least four important types of contribution: TA detection may allow etiologic diagnosis in transitional phases of NC, with non-characteristic images; in final stages of evolution of cysticercoids in the CNS, lesions may not appear on CT or MRI, and TA detection may contribute to a definite etiologic diagnosis; TA detection may permit diagnosis of NC in some patients with previous negative tests for antibody detection in CSF; TA detection may represent an accurate marker of disease activity in the epileptic form of NC.

  8. Virtual reality exposure therapy for active duty soldiers.

    Reger, Greg M; Gahm, Gregory A


    Virtual reality exposure (VRE) therapy is a promising treatment for a variety of anxiety disorders and has recently been extended to the treatment of posttraumatic stress disorder (PTSD). In this article, the authors briefly review the rationale for VRE and its key processes. They illustrate the treatment with an active-duty Army soldier diagnosed with combat-related PTSD. Six sessions of VRE were provided using an immersive simulation of a military convoy in Iraq. Self-reported PTSD symptoms and psychological distress were reduced at posttreatment relative to pretreatment reports, as assessed by the PTSD Checklist-Military Version and the Behavior and Symptom Identification Scale-24. The case outcomes parallel those reported in the research with other disorders and suggest the applicability of VRE in treating active duty soldiers with combat-related PTSD.

  9. Education as alternative to violence: child soldiers in Sierra Leone

    Chema Caballero


    Full Text Available Education plays a key role in the process of rehabilitation and reintegracion of child soldiers and helps them to overcome the psysologial and moral impact of the war. Children see education as their gateway to a different life away from the violence and suffering they experienced during the years lived with the armed grups. The desire to change life makes children strive in this activity devouting great effort to stand out above the rest of their classmates. The disruption of the educational process generates great frustration for former child soldiers. Therefore, all reintegration and rehabilitation programs must invest time and resources to ensure that these children have secured their training until the end.

  10. Resilience to traumatic exposure among soldiers deployed in combat.

    Schaubroeck, John M; Riolli, Laura T; Peng, Ann Chunyan; Spain, Everett S


    We examined the influence of positive psychological capital (PsyCap), a metaconstruct that combines established psychological predispositions to be resilient to stress, on the well-being of soldiers during combat deployment. Among U.S. Army personnel deployed in Iraq, cognitive appraisal of stress mediated the effects of trait PsyCap on health symptoms. The indirect effects through appraisal were moderated by levels of exposure to potentially traumatic stimuli. Trait PsyCap covaried more strongly with cognitive appraisals, and had stronger indirect effects through appraisal on health, among soldiers in units with higher levels of potentially traumatic exposures. We discuss implications for research on resilience to trauma in the workplace and for helping workers cope with potentially traumatic exposures.

  11. The Bluebirds: World War I Soldiers' Experiences of Occupational Therapy.

    Pettigrew, Judith; Robinson, Katie; Moloney, Stephanie

    More is known about the experience of occupational therapists than the experience of patients during the profession's early years. We examined soldiers' experiences of occupational therapy in American Base Hospital 9 in France during World War I through analysis of a 53-line poem by Corporal Frank Wren contained in the unpublished memoir of occupational therapy reconstruction aide Lena Hitchcock. Historical documentary research methods and thematic analysis were used to analyze the poem, the memoir, and the hospital's published history. The poem describes the activities engaged in during occupational therapy, equipment used, and the context of therapy. It articulates positive dimensions of the experience of engaging in activities, including emotional benefits, diversion, and orthopedic benefits. Previous historical research has identified core philosophical premises about the use of occupational therapy; in this article, the enactment of these principles is established through the analysis of a soldier's account of receiving occupational therapy.

  12. Colombian Soldiers in Nazi Germany, 1934-1937

    Luis Eduardo Bosemberg


    Full Text Available The article aims to narrate the visit the Colombian militaries paid to the Nazi Germany. It is based on the idea that this presence was not only part of the relations between the two countries but, instead, it contributed to the formation of networks in interrelated spaces. These soldiers got into the German military world which, in turn, managed to infiltrate Colombia as well. The article inquires into what the parties involved wanted, who participated, what attitudes Colombians had towards that country, if those soldiers were nazis. It is concluded that three missions were sent and they do not only visited Germany, but they were also in other countries. Their reports are full of admiration for the host country and the journey raised their criticism, which is evidenced in the constant compasions between the two countries. However, knowledge transfer did not have much effect because American influence grew and WWII broke out shortly after.

  14. Repeated-sprint ability and aerobic fitness.

    Thébault, Nicolas; Léger, Luc A; Passelergue, Philippe


    The purpose of this study was to reinvestigate the relationship between aerobic fitness and fatigue indices of repeated-sprint ability (RSA), with special attention to methodological normalization. Soldiers were divided into low (n = 10) and high (n = 9) fitness groups according to a preset maximal aerobic speed (MAS) of 17 km·h(-1) (∼60 ml O2·kg(-1)·min) measured with the University of Montreal Track Test (UMTT). Subjects' assessment included the RSA test (3 sets of 5 40-m sprints with 1-minute rest between sprints and 1.5 minutes between sets), a 40-m sprint (criterion test used in the computation of fatigue indices for the RSA test), strength and power measurement of the lower limbs, and the 20-m shuttle run test (20-m SRT) and the UMTT, which are measures of maximal aerobic power. The highest correlation with the RSA fatigue indices was obtained with the 20-m SRT (r = 0.90, p = 0.0001, n = 19), a test with 180° direction changes and accelerations and decelerations. The lower correlation (r = 0.66, p repeated sprints and achieved better recovery between series. A MAS of at least 17 km·h(-1) favors constant and high speed level during repeated sprints. From a practical point of view, a high aerobic fitness is a precious asset in counteracting fatigue in sports with numerous sprint repetitions.

  1. FOCU:S--future operator control unit: soldier

    O'Brien, Barry J.; Karan, Cem; Young, Stuart H.


    The U.S. Army Research Laboratory's (ARL) Computational and Information Sciences Directorate (CISD) has long been involved in autonomous asset control, specifically as it relates to small robots. Over the past year, CISD has been making strides in the implementation of three areas of small robot autonomy, namely platform autonomy, Soldier-robot interface, and tactical behaviors. It is CISD's belief that these three areas must be considered as a whole in order to provide Soldiers with useful capabilities. In addressing the Soldier-robot interface aspect, CISD has begun development on a unique dismounted controller called the Future Operator Control Unit: Soldier (FOCU:S) that is based on an Apple iPod Touch. The iPod Touch's small form factor, unique touch-screen input device, and the presence of general purpose computing applications such as a web browser combine to give this device the potential to be a disruptive technology. Setting CISD's implementation apart from other similar iPod or iPhone-based devices is the ARL software that allows multiple robotic platforms to be controlled from a single OCU. The FOCU:S uses the same Agile Computing Infrastructure (ACI) that all other assets in the ARL robotic control system use, enabling automated asset discovery on any type of network. Further, a custom ad hoc routing implementation allows the FOCU:S to communicate with the ARL ad hoc communications system and enables it to extend the range of the network. This paper will briefly describe the current robotic control architecture employed by ARL and provide short descriptions of existing capabilities. Further, the paper will discuss FOCU:S specific software developed for the iPod Touch, including unique capabilities enabled by the device's unique hardware.

  6. Limitations imposed by wearing armour on Medieval soldiers' locomotor performance.

    Askew, Graham N; Formenti, Federico; Minetti, Alberto E


    In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown. We investigated the mechanics and the energetic cost of locomotion in armour, and determined the effects on physical performance. We found that the net cost of locomotion (C(met)) during armoured walking and running is much more energetically expensive than unloaded locomotion. C(met) for locomotion in armour was 2.1-2.3 times higher for walking, and 1.9 times higher for running when compared with C(met) for unloaded locomotion at the same speed. An important component of the increased energy use results from the extra force that must be generated to support the additional mass. However, the energetic cost of locomotion in armour was also much higher than equivalent trunk loading. This additional cost is mostly explained by the increased energy required to swing the limbs and impaired breathing. Our findings can predict age-associated decline in Medieval soldiers' physical performance, and have potential implications in understanding the outcomes of past European military battles.

  7. Combined foraging strategies and soldier behaviour in Nasutitermes aff. coxipoensis (Blattodea: Termitoidea: Termitidae).

    Almeida, Camilla S; Cristaldo, Paulo F; Florencio, Daniela F; Cruz, Nayara G; Santos, Abraão A; Oliveira, Alexandre P; Santana, Alisson S; Ribeiro, Efrem J M; Lima, Ana P S; Bacci, Leandro; Araújo, Ana P A


    A range of behavioural strategies and sensory abilities allows animals to minimize costs involved in food search. By building a network of tunnels and presenting a large number of soldiers (i.e., trophically dependent individuals), Nasutitermes spp. termites feature behaviours that imply additional costs during this process. Here we evaluated N. aff. coxipoensis foraging strategies focusing on the role of soldiers during foraging. Field experiments were carried out via nests transplantation to dune areas, and laboratory experiments evaluated termite responses to sternal gland chemical signals from workers and soldiers. N. aff. coxipoensis presented primarily nocturnal foraging. Soldiers typically initiated foraging; however, in established trails, the number of workers was always higher than that of soldiers. The number of trails remained constant over time, while the number of tunnels increased linearly over time. A higher proportion of tunnels originated in surrounding areas than directly from the nests. At observation points with tunnels, there were more stationary than walking soldiers; the opposite was true at observation points without tunnels. In mixed groups, the workers chose to follow soldier chemical signals, and in these groups, soldiers were the first to follow trails. Our results allowed us to identify a not common foraging strategy in termite species; which included the establishment of trails followed by construction of tunnels. Such foraging strategies occur predominantly at night and soldiers play a key role in the foraging process. This foraging strategy reported here seems to be employed to optimize energetic gain.

  8. Post-traumatic stress symptoms among former child soldiers in Sierra Leone: follow-up study.

    Former child soldiers are at risk of developing post-traumatic stress disorder (PTSD); however, the trajectory of symptoms has yet to be examined. The risk and protective factors associated with PTSD symptom change among former child soldiers in Sierra Leone were investigated. Data from 243 former child soldiers (mean age 16.6 years, 30% female) were analysed. Self-reported rates of possible PTSD using standard cut-off points declined from 32% to 16% 4 years later (Pchild soldiers despite limited access to care. Family and community support played a vital part in promoting psychological adjustment.

  9. Fit for purpose: Australia's National Fitness Campaign.

    Collins, Julie A; Lekkas, Peter


    During a time of war, the federal government passed the National Fitness Act 1941 to improve the fitness of the youth of Australia and better prepare them for roles in the armed services and industry. Implementation of the National Fitness Act made federal funds available at a local level through state-based national fitness councils, which coordinated promotional campaigns, programs, education and infrastructure for physical fitness, with volunteers undertaking most of the work. Specifically focused on children and youth, national fitness councils supported the provision of children's playgrounds, youth clubs and school camping programs, as well as the development of physical education in schools and its teaching and research in universities. By the time the Act was repealed in 1994, fitness had become associated with leisure and recreation rather than being seen as equipping people for everyday life and work. The emergence of the Australian National Preventive Health Agency Act 2010 offers the opportunity to reflect on synergies with its historic precedent.

  11. MR imaging of pulsatile CSF movement in hydrocephalus communicans before and after CSF shunt implantation. Magnetresonanztomographische Darstellung der Liquorpulsbewegung bei Hydrozephalus communicans vor und nach Shuntanlage

Neurochirurgie, Bundeswehrkrankenhaus Ulm (Germany)); Friedrich, J.M. (Abt. Radiologie 1, Ulm Univ. (Germany)); Schnarkowski, P. (Abt. Radiologie 1, Ulm Univ. (Germany))


    16 patients with hydrocephalus communicans and 5 healthy volunteers were examined to demonstrate the pattern of the pulsatile CSF flow. After implantation of a CSF shunt system the same patients were examined again to show the influence of the shunt on the CSF pulsations. We used a flow-sensitised, cardiac-gated 2D FLASH sequence and analysed the phase and magnitude images. It could be shown that most patients (n=12) had a hyerdynamic pulsatile flow preoperatively. After shunt implantation the pulsatile CSF motion and the clinical symptoms were improved in 8 of these patients. MRI of pulsatile CSF flow movement seems to be a helpful noninvasive tool to estimate the prognosis of a shunt implantation in patients with hydrocephalus communicans. (orig.)

  12. Soldier-specific modification of the mandibular motor neurons in termites.

    Yuki Ishikawa

    Full Text Available Social insects exhibit a variety of caste-specific behavioral tendencies that constitute the basis of division of labor within the colony. In termites, the soldier caste display distinctive defense behaviors, such as aggressively attacking enemies with well-developed mandibles, while the other castes retreat into the colony without exhibiting any aggressive response. It is thus likely that some form of soldier-specific neuronal modification exists in termites. In this study, the authors compared the brain (cerebral ganglion and the suboesophageal ganglion (SOG of soldiers and pseudergates (workers in the damp-wood termite, Hodotermopsis sjostedti. The size of the SOG was significantly larger in soldiers than in pseudergates, but no difference in brain size was apparent between castes. Furthermore, mandibular nerves were thicker in soldiers than in pseudergates. Retrograde staining revealed that the somata sizes of the mandibular motor neurons (MdMNs in soldiers were more than twice as large as those of pseudergates. The enlargement of MdMNs was also observed in individuals treated with a juvenile hormone analogue (JHA, indicating that MdMNs become enlarged in response to juvenile hormone (JH action during soldier differentiation. This enlargement is likely to have two functions: a behavioral function in which soldier termites will be able to defend more effectively through relatively faster and stronger mandibular movements, and a developmental function that associates with the development of soldier-specific mandibular muscle morphogenesis in termite head. The soldier-specific enlargement of mandibular motor neurons was observed in all examined species in five termite families that have different mechanisms of defense, suggesting that such neuronal modification was already present in the common ancestor of termites and is significant for soldier function.

  15. Phorbol ester-treated human acute myeloid leukemia cells secrete G-CSF, GM-CSF and erythroid differentiation factor into serum-free media in primary culture.

    Scher, W; Eto, Y; Ejima, D; Den, T; Svet-Moldavsky, I A


    Upon treatment with the phorbol ester, tetradecanoylphorbol 13-acetate (PMA), peripheral mononuclear blood cells from patients with acute myeloid leukemia secrete into serum-free cell-conditioned media (PMA-CCM) at least three distinct nondialysable 'hematopoietic' factors: granulocyte-colony-stimulating factor (G-CSF), granulocyte/macrophage-colony-stimulating factor (GM-CSF) and erythroid differentiation factor (EDF, activin A). G-CSF was identified by its stimulation of [3H]thymidine incorporation into a G-CSF-responsive cell line, NSF-60, and the inhibition of its stimulation by a G-CSF-specific monoclonal antibody (MAB). GM-CSF was identified by its stimulation of [3H]thymidine incorporation into a GM-CSF-responsive line, TALL-101, and the inhibition of its stimulation by a GM-CSF-specific MAB. EDF was identified by its ability to stimulate erythroid differentiation in mouse erythroleukemia cell lines, its identical retention times to those of authentic EDF on three successive reverse-phase HPLC columns and characterization of its penultimate N-terminal residue as leucine which is the same as that of authentic EDF. Both authentic EDF and the erythroid-stimulating activity in PMA-CCM were found to act synergistically with a suboptimal inducing concentration of a well-studied inducing agent, dimethyl sulfoxide, in inducing erythroid differentiation. In addition, a fourth activity was observed in PMA-CCM: normal human fetal bone marrow cell-proliferation stimulating activity (FBMC-PSA). FBMC-PSA was identified by its ability to stimulate the growth of granulocytes and macrophages in FBMC suspension cultures, which neither recombinant G-CSF or GM-CSF were found to do.

  19. A Pretty Good Fit

    Erickson, Tim


    We often look for a best-fit function to a set of data. This article describes how a "pretty good" fit might be better than a "best" fit when it comes to promoting conceptual understanding of functions. In a pretty good fit, students design the function themselves rather than choosing it from a menu; they use appropriate variable names; and they…

  1. Phenotypically plastic traits regulate caste formation and soldier function in polyembryonic wasps.

    Smith, M S; Milton, I; Strand, M R


    Polyembryonic encyrtid wasps are parasitoids that have evolved a clonal form of embryogenesis and a caste system where some progeny become reproducing wasps whereas others develop into a sterile soldier caste. Theory based on the biology of Copidosoma floridanum predicts that the primary role of soldier larvae is to mediate conflict over sex ratio, which also favours female-biased soldier production. Other data, however, suggest that female-biased soldier production reflects a developmental constraint. Here, we assessed whether female-biased soldier function by polyembryonic wasps reflects sex-specific adaptation or constraint by conducting comparative studies with Copidosoma bakeri, a species that produces clutch sizes similar to C. floridanum yet rarely produces broods associated with sex ratio conflict. Our results indicate that the oviposition behaviour of adults, development of progeny and function of soldier larvae differ greatly between C. bakeri and C. floridanum. These findings indicate that caste formation and soldier function in polyembryonic encyrtid wasps are regulated by phenotypically plastic traits. Our results further suggest that the primary function of the soldier caste in some species is defence of host resources from competitors whereas in others it is the resolution of sex ratio conflict.

  11. Analysis of posttraumatic stress disorders in Polish soldiers who returned from stabilization mission in Iraq

    Skotnicka, Justyna


    Full Text Available Aims. The aim of the survey was to establish whether PTSD is present among Polish soldiers returning from a one-year deployment to Iraq and an analysis of its individual symptoms. Methods. Sixty soldiers were examined, including 30 who returned from the Iraqi mission and 30 who remained in Poland. Five analysing devices were used: (IPSA, (STAI, (BDI, a PTSD questionnaire and a socio-demographical form. Results: A significant number of soldiers experienced a traumatic event during the mission in Iraq. Although the Iraq deployment did not change the level of depression and anxiety among the two groups of soldiers, disproportions were found in the range of anger level intensity, which was significantly higher among soldiers who returned from Iraq. Conclusion. Stabilisation mission and the experience of a traumatic event influenced the biological and psychological functioning patterns among soldiers who returned from Iraq. The manifestations of this were emotional and physiological reactions that the soldiers experienced (nightmares, excessive sweating, increased heartbeat rate, stressful reactions in situations similar to the traumatic occurrence and intensified responses to them. However, contrary to the assumptions, it was not concluded that soldiers who returned from Iraq are suffering from PTSD.

  17. Growing up in armed groups: trauma and aggression among child soldiers in DR Congo

    Katharin Hermenau


    Full Text Available Background: Child soldiers are often both victims and perpetrators of horrendous acts of violence. Research with former child soldiers has consistently shown that exposure to violence is linked to trauma-related disorders and that living in a violent environment is correlated with enhanced levels of aggression. Objective: To gain more insight into the experiences and the mental health status of former child soldiers, we conducted a survey with N=200 former child soldiers and adult combatants in the DR Congo. Methods: We conducted semi-structured interviews concerning military experiences, experienced and perpetrated violence, and mental health. Results: Former child soldiers reported more experienced and perpetrated violence, a greater severity of trauma-related suffering, as well as higher appetitive aggression than adult ex-combatants. Appetitive aggression was related to more perpetrated violence, higher military ranks, voluntary recruitment and higher rates of reenlistments in former child soldiers. Conclusions: Our results indicate that growing up in an armed group is related to higher levels of trauma-related disorders and aggressive behavior. This may explain the challenge of reintegrating former child soldiers. It is thus important to consider mental health problems, particularly trauma-related disorders and aggressive behavior, of former child soldiers for designing adequate reintegration programs.

    Betancourt, Theresa S; Borisova, Ivelina I; de la Soudière, Marie; Williamson, John


    To examine associations between war experiences, mental health, and gender in a sample of male and female Sierra Leonean former child soldiers. A total of 273 former child soldiers (29% females) were assessed for depression and anxiety by using the Hopkins Symptoms Checklist, and for hostility, confidence, and prosocial attitudes by using an instrument developed for use with Sierra Leonean child soldiers. The former child soldiers had witnessed and perpetrated violence at largely comparable rates, although females experienced higher rates of rape (p child soldiers who lost caregivers were also more vulnerable to depression (p child soldiers. In our sample, female and male child soldiers experienced comparable levels of most war exposures. Female soldiers reported higher rates of rape and lower levels of adaptive outcomes. Toxic forms of violence (killing or injuring; rape) were associated with particularly poor outcomes. Although all boys and girls who experience rape and loss of caregivers are generally at risk for mental health problems, boys in our sample demonstrated increased vulnerability; these findings indicate a need for more inclusive mental health services.

  7. A Csf1r-EGFP Transgene Provides a Novel Marker for Monocyte Subsets in Sheep.

    Pridans, Clare; Davis, Gemma M; Sauter, Kristin A; Lisowski, Zofia M; Corripio-Miyar, Yolanda; Raper, Anna; Lefevre, Lucas; Young, Rachel; McCulloch, Mary E; Lillico, Simon; Milne, Elspeth; Whitelaw, Bruce; Hume, David A


    Expression of Csf1r in adults is restricted to cells of the macrophage lineage. Transgenic reporters based upon the Csf1r locus require inclusion of the highly conserved Fms-intronic regulatory element for expression. We have created Csf1r-EGFP transgenic sheep via lentiviral transgenesis of a construct containing elements of the mouse Fms-intronic regulatory element and Csf1r promoter. Committed bone marrow macrophage precursors and blood monocytes express EGFP in these animals. Sheep monocytes were divided into three populations, similar to classical, intermediate, and nonclassical monocytes in humans, based upon CD14 and CD16 expression. All expressed EGFP, with increased levels in the nonclassical subset. Because Csf1r expression coincides with the earliest commitment to the macrophage lineage, Csf1r-EGFP bone marrow provides a tool for studying the earliest events in myelopoiesis using the sheep as a model.

  8. CSF1R mutations in hereditary diffuse leukoencephalopathy with spheroids are loss of function

    Pridans, Clare; Sauter, Kristin A.; Baer, Kristin; Kissel, Holger; Hume, David A.


    Hereditary diffuse leukoencephalopathy with spheroids (HDLS) in humans is a rare autosomal dominant disease characterized by giant neuroaxonal swellings (spheroids) within the CNS white matter. Symptoms are variable and can include personality and behavioural changes. Patients with this disease have mutations in the protein kinase domain of the colony-stimulating factor 1 receptor (CSF1R) which is a tyrosine kinase receptor essential for microglia development. We investigated the effects of these mutations on Csf1r signalling using a factor dependent cell line. Corresponding mutant forms of murine Csf1r were expressed on the cell surface at normal levels, and bound CSF1, but were not able to sustain cell proliferation. Since Csf1r signaling requires receptor dimerization initiated by CSF1 binding, the data suggest a mechanism for phenotypic dominance of the mutant allele in HDLS.

  9. Inhibition of CSF-1R supports T-cell mediated melanoma therapy.

    Marjolein Sluijter

    Full Text Available Tumor associated macrophages (TAM can promote angiogenesis, invasiveness and immunosuppression. The cytokine CSF-1 (or M-CSF is an important factor of TAM recruitment and differentiation and several pharmacological agents targeting the CSF-1 receptor (CSF-1R have been developed to regulate TAM in solid cancers. We show that the kinase inhibitor PLX3397 strongly dampened the systemic and local accumulation of macrophages driven by B16F10 melanomas, without affecting Gr-1(+ myeloid derived suppressor cells. Removal of intratumoral macrophages was remarkably efficient and a modest, but statistically significant, delay in melanoma outgrowth was observed. Importantly, CSF-1R inhibition strongly enhanced tumor control by immunotherapy using tumor-specific CD8 T cells. Elevated IFNγ production by T cells was observed in mice treated with the combination of PLX3397 and immunotherapy. These results support the combined use of CSF-1R inhibition with CD8 T cell immunotherapy, especially for macrophage-stimulating tumors.

  10. Comparing elite soldiers' perceptions of psychological and physical demands during military training.

    Thomas, Jeffrey L; Adler, Amy B; Wittels, Peter; Enne, Robert; Johannes, Bernd


    This research examined the impact of psychological and physical demands on a group of elite soldiers (N = 9) before, during and after training exercises involving routine and unrehearse tasks. Based on the psychological concept of toughening, we expected soldier responses to unrehearsed demands to be les resilient than to routine training demands. As hypothesized soldiers rated their perceptions of physical and psychologica demands higher during the unrehearsed training phase of the study. It was also hypothesized that soldiers would recover more from physical demands than from psychological de mands after the training exercise. Although a trend in the data marginally supported this hypothesis, a note of caution is warranted because of the small sample size. Limitations and implications of the study are discussed, with particular emphasis on the dual importance of psychological and physical training in preparing soldiers for mission demands.

  11. The frequency and effecting factors of consanguineous marriage in a group of soldiers in Ankara.

    Kir, Tayfun; Güleç, Mahir; Bakir, Bilal; Hoşjgönül, Esat; Tümerdem, Nazmi


    This cross-sectional study was carried out to investigate the frequency of consanguineous marriage in a group of army conscripts in Ankara and the factors affecting this. Of 4153 soldiers, 387 were married. The rate of marriage between first cousins was found to be 19.1%, and the overall rate of consanguineous marriage was 24.1%. Consanguineous marriage was found to be significantly prevalent among soldiers who were born in and still living in the Eastern region; among those who lived in villages; among those whose parents as well as themselves had low educational levels; and among those whose marriages were arranged by their families. Neither the payment of bride-price nor the presence of consanguinity between parents was a significant factor for consanguineous marriage. In addition, the age of the soldier and the age at marriage were significantly lower among soldiers married to first cousins than among soldiers whose marriages were not consanguineous.

  12. Soldiers' Preferences Regarding Sperm Preservation, Posthumous Reproduction, and Attributes of a Potential "Posthumous Mother".

    Bokek-Cohen, Ya'arit; Ravitsky, Vardit


    We present study results regarding soldiers' willingness to conduct posthumous reproduction. Two hundred twelve Israeli soldiers filled in a questionnaire designed to examine their willingness to cryopreserve sperm and evaluate in which familial circumstances they would consent to posthumous reproduction. They ranked the desirability of 46 attributes of a potential mother and a life partner. Findings indicate a relatively high predisposition in favor of posthumous-assisted reproduction; the wishes of soldiers' parents had much more influence on soldiers' willingness to pursue this technology than those of a partner. Soldiers preferred "feminine" jobs for a potential mother that would allow her to dedicate herself to child-rearing. The desired traits of such a mother were rated similarly to partner preferences; however, significant differences were found in attributes that are most related to the potential mother's devotion to maternity. Interpretations of these findings are contextualized in relation to ethical and bereavement considerations.

  13. Sleep disturbances among Swedish soldiers after military service abroad.

    Pettersson, Karolina; Saers, Johannes; Lindberg, Eva; Janson, Christer


    Aims Since 1956, more than 100,000 Swedish soldiers have served abroad on various international missions. The aim of this paper was to determine whether there was a connection between military service abroad and sleep disorders among Swedish soldiers. Methods The prevalence of sleep disturbances among 1,080 veterans from Kosovo and Afghanistan was compared with almost 27,000 Swedes from a general population sample, using propensity score matching and logistic regression. The sleep disturbances studied were habitual snoring, difficulty inducing sleep (DIS), difficulty maintaining sleep (DMS), early morning awakenings (EMA), and excessive daytime sleepiness (EDS). Insomnia was defined as having at least one of DIS, DMS, or EMA. The covariates used in the matching and adjustments were age, gender, smoking habits, BMI, education, ever having had asthma, moist snuff, and exercise habits. Results The veterans had a significantly lower prevalence of insomnia (26.2% versus 30.4%) and EDS (22.7% versus 29.4%) compared with a matched group from the reference population, using propensity score matching. Analyses with logistic regression showed that belonging to the military population was related to a lower risk of having DMS (adjusted OR (95% CI) 0.77 (0.64-0.91)), insomnia (OR 0.82 (0.71-0.95)), and EDS (OR 0.74 (0.63-0.86)), whereas no significant difference was found for snoring, DIS, and EMA. Conclusion Swedish veterans have fewer problems with insomnia and daytime sleepiness than the general Swedish population. The explanation of our findings may be the selection processes involved in becoming a soldier and when sampling personnel for military assignments abroad.

  14. Modelling of soldier fly halteres for gyroscopic oscillations

    Rizuwana Parween


    Full Text Available Nature has evolved a beautiful design for small-scale vibratory rate-gyro in the form of dipteran halteres that detect body rotations via Coriolis acceleration. In most Diptera, including soldier fly, Hermetia illucens, halteres are a pair of special organs, located in the space between the thorax and the abdomen. The halteres along with their connecting joint with the fly's body constitute a mechanism that is used for muscle-actuated oscillations of the halteres along the actuation direction. These oscillations lead to bending vibrations in the sensing direction (out of the haltere's actuation plane upon any impressed rotation due to the resulting Coriolis force. This induced vibration is sensed by the sensory organs at the base of the haltere in order to determine the rate of rotation. In this study, we evaluate the boundary conditions and the stiffness of the anesthetized halteres along the actuation and the sensing direction. We take several cross-sectional SEM (scanning electron microscope images of the soldier fly haltere and construct its three dimensional model to get the mass properties. Based on these measurements, we estimate the natural frequency along both actuation and sensing directions, propose a finite element model of the haltere's joint mechanism, and discuss the significance of the haltere's asymmetric cross-section. The estimated natural frequency along the actuation direction is within the range of the haltere's flapping frequency. However, the natural frequency along the sensing direction is roughly double the haltere's flapping frequency that provides a large bandwidth for sensing the rate of rotation to the soldier flies.

  15. Conductance to outflow of CSF in normal pressure hydrocephalus.

    Børgesen, S E


    Normal pressure hydrocephalus (NPH) is defined as a combination of dementia, gait disturbances and/or urinary incontinence, hydrocephalus, and a normal intracranial mean pressure. The clinical effect of CSF shunting in patients with this syndrome is sometimes striking, but generally only 50-60% of the shunted patients benefit from the treatment. It is assumed that the condition is caused by reduced conductance to outflow of CSF ( Cout ). A clinically usable method for the measurement of Cout has been developed. Cout has been measured in 80 patients with NPH. The results of clinical examination, computed tomography (CT), long-term intracranial pressure recording, isotope cisternography (ICG), and Cout have been compared to the clinical results of shunting 3 and 12 months after operation. Among the preoperative investigations Cout proved to have the best diagnostic specificity and sensitivity. Thus, selection of patients for shunting on the basis of Cout should lead to a satisfyingly high success rate. The different methods for measurement of Cout are discussed, and a theory on the pathophysiology of NPH is proposed. A clinical investigational programme, based on the results from clinical examination, CT, pressure recording, and measurements of Cout is suggested.

  19. [Rehabilitation and reintegration of soldiers injured on deployment].

    de Montleau, Franck; Boussaud, Marie; Dascalescu, Délia; Granier, Claire; Allagil, Constance; Daudin, Marianne


    The participation of the French army in the Afghan conflict has highlighted the need for discussion and action regarding the pathway, rehabilitation and reintegration of soldiers who have been physically or psychologically injured. Clinical experience demonstrates that difficulties are less likely to appear during the initial treatment phase than later on, when there is less group support and there are fewer visible effects of the recognition on the part of the institution. It is important to strengthen the links between healthcare personnel and institutional players, in order to optimise the medical and social care of these war casualties.

  2. Translocation and expression of CSF1 in pigmented villonodular synovitis, tenosynovial giant cell tumor, rheumatoid arthritis and other reactive synovitides.

    Cupp, John S; Miller, Melinda A; Montgomery, Kelli D; Nielsen, Torsten O; O'Connell, John X; Huntsman, David; van de Rijn, Matt; Gilks, Cyril B; West, Robert B


    We recently demonstrated that CSF1, the ligand of the tyrosine kinase receptor, CSF1R, can be translocated in pigmented villonodular synovitis (PVNS) and tenosynovial giant cell tumor (TGCT). In this study, we evaluated the staining characteristics of PVNS/TGCT and reactive synovitides for CSF1 and CSF1R by in situ hybridization and immunohistochemistry on tissue microarrays and correlated these findings with the recently described translocation. We collected specimens of TGCT/PVNS from 60 patients and of rheumatoid arthritis and other reactive synovitides from 74 patients. We identify 2 groups of PVNS and TGCT cases by the presence of CSF1 translocation and CSF1 expression. The first group (35 of 57 cases; 61%) had both the CSF1 translocation and high expression of CSF1 RNA, confirming our previous findings. Interestingly, a second group (22 of 57 cases; 39%) was identified that showed high expression of CSF1 RNA or CSF1 protein but did not have the translocation. The rheumatoid arthritis and reactive synovitis specimens showed localization of CSF1 RNA and protein to the synovial lining cells, implying a possible role for CSF1 in the pathogenesis of these lesions. As the CSF1 translocation is postulated to play an important role in the biology of PVNS/TGCT, the consistent presence of CSF1 expression in translocation-negative cases implies that other mechanisms can lead to CSF1 up-regulation. The consistent presence of CSF1 overexpression in all cases of PVNS/TGCT and reactive synovitides suggests both an important role for CSF1 in the spectrum of synovial pathologies and the possibility of targeting the CSF1/CSF1R interaction therapeutically.

  3. Plasma levels of M-CSF are increased in ANCA-associated vasculitides with active nephritis

    Giuseppe A. Ramirez


    Full Text Available Anti-Neutrophil Cytoplasmic Antibodies (ANCA-associated vasculitides (AAV are characterized by small vessel injury and in some cases granulomatous lesions and glomerular inflammation. The pathogenic bases of these clinical phenotypes are incompletely understood, but evidence from patients with AAV and other inflammatory diseases suggest a role for monocyte/macrophages in the perpetuation of tissue injury. Macrophage colony stimulating factor (M-CSF is a promoter of monocyte recruitment and macrophage proliferation, involved in mesangial cell proliferation and experimental nephritis development. Serum concentrations of M-CSF mark and herald the onset of lupus nephritis. Plasma samples from 29 patients with AAV (18 granulomatosis with polyangiitis, GPA, 6 eosinophilic granulomatosis with polyangiitis, EGPA, and 5 microscopic polyangiitis, MPA and from 10 healthy controls were collected together with clinical data. Patients with AAV had higher levels of M-CSF when compared to controls. M-CSF levels correlated positively with the BVAS, serum C-reactive protein and erythrocyte sedimentation rate, while haemoglobin correlated inversely with M-CSF. Patients with active renal disease had significantly higher levels of M-CSF when compared to the other subgroups. M-CSF levels did not differ between ANCA subserotypes and were not associated with the involvement of other organs. In conclusion, M-CSF is higher in patients with AAV and active nephritis and could contribute to the pathogenesis of these diseases. In addition, M-CSF could behave as a useful marker of renal involvement in AAV.

    Objective: To investigate the functions of nM-CSF in malignant cells. Methods: recombinant M-CSF was targeted into cell nucleus by employing a eukaryotic expression plasmid vector pCMV/myc/nuc. The constructed plasmid was transfected into cells of EBV transformed lymphoblastoid cell line (LCL). RT-PCR, Western blot and immunofluorescent staining showed that recombinant M-CSF was localized into LCL cell nucleus. The transgenic cells showed elevated proliferation potential, enhanced resistance to apoptosis and increased ability of in vitro migration. Conclusion: Nucleus presenting M-CSF might act as a promoting factor in the processes of cell malignancy.

    Sustained release of functional growth factors can be considered as a beneficial methodology for wound healing. In this study, recombinant human granulocyte colony-stimulating factor (G-CSF)-loaded chitosan nanoparticles were incorporated in Poly(ε-caprolactone) (PCL) nanofibers, followed by surface coating with collagen type I. Physical and mechanical properties of the PCL nanofibers containing G-CSF loaded chitosan nanoparticles PCL/NP(G-CSF) and in vivo performance for wound healing were investigated. G-CSF structural stability was evaluated through SDS_PAGE, reversed phase (RP) HPLC and size-exclusion chromatography, as well as circular dichroism. Nanofiber/nanoparticle composite scaffold was demonstrated to have appropriate mechanical properties as a wound dresser and a sustained release of functional G-CSF. The PCL/NP(G-CSF) scaffold showed a suitable proliferation and well-adherent morphology of stem cells. In vivo study and histopathological evaluation outcome revealed that skin regeneration was dramatically accelerated under PCL/NP(G-CSF) as compared with control groups. Superior fibroblast maturation, enhanced collagen deposition and minimum inflammatory cells were also the beneficial properties of PCL/NP(G-CSF) over the commercial dressing. The synergistic effect of extracellular matrix-mimicking nanofibrous membrane and G-CSF could develop a suitable supportive substrate in order to extensive utilization for the healing of skin wounds. © 2017 Wiley Periodicals Inc.

  6. Pleiotropic effects of extended blockade of CSF1R signaling in adult mice.

    Sauter, Kristin A; Pridans, Clare; Sehgal, Anuj; Tsai, Yi Ting; Bradford, Barry M; Raza, Sobia; Moffat, Lindsey; Gow, Deborah J; Beard, Philippa M; Mabbott, Neil A; Smith, Lee B; Hume, David A


    We investigated the role of CSF1R signaling in adult mice using prolonged treatment with anti-CSF1R antibody. Mutation of the CSF1 gene in the op/op mouse produces numerous developmental abnormalities. Mutation of the CSF1R has an even more penetrant phenotype, including perinatal lethality, because of the existence of a second ligand, IL-34. These effects on development provide limited insight into functions of CSF1R signaling in adult homeostasis. The carcass weight and weight of several organs (spleen, kidney, and liver) were reduced in the treated mice, but overall body weight gain was increased. Despite the complete loss of Kupffer cells, there was no effect on liver gene expression. The treatment ablated OCL, increased bone density and trabecular volume, and prevented the decline in bone mass seen in female mice with age. The op/op mouse has a deficiency in pancreatic β cells and in Paneth cells in the gut wall. Only the latter was reproduced by the antibody treatment and was associated with increased goblet cell number but no change in villus architecture. Male op/op mice are infertile as a result of testosterone insufficiency. Anti-CSF1R treatment ablated interstitial macrophages in the testis, but there was no sustained effect on testosterone or LH. The results indicate an ongoing requirement for CSF1R signaling in macrophage and OCL homeostasis but indicate that most effects of CSF1 and CSF1R mutations are due to effects on development.

  7. Body mass index is associated with biological CSF markers of core brain pathology of Alzheimer's disease.

    Ewers, Michael; Schmitz, Susanne; Hansson, Oskar; Walsh, Cathal; Fitzpatrick, Annette; Bennett, David; Minthon, Lennart; Trojanowski, John Q; Shaw, Leslie M; Faluyi, Yetunde O; Vellas, Bruno; Dubois, Bruno; Blennow, Kaj; Buerger, Katharina; Teipel, Stefan J; Weiner, Michael; Hampel, Harald


    Weight changes are common in aging and Alzheimer's disease (AD) and postmortem findings suggest a relation between lower body mass index (BMI) and increased AD brain pathology. In the current multicenter study, we tested whether lower BMI is associated with higher core AD brain pathology as assessed by cerebrospinal fluid (CSF)-based biological markers of AD in 751 living subjects: 308 patients with AD, 296 subjects with amnestic mild cognitive impairment (MCI), and 147 elderly healthy controls (HC). Based upon a priori cutoff values on CSF concentration of total tau and beta-amyloid (Aβ(1-42)), subjects were binarized into a group with abnormal CSF biomarker signature (CSF+) and those without (CSF-). Results showed that BMI was significantly lower in the CSF+ when compared with the CSF- group (F = 27.7, df = 746, p < 0.001). There was no interaction between CSF signature and diagnosis or apolipoprotein E (ApoE) genotype. In conclusion, lower BMI is indicative of AD pathology as assessed with CSF-based biomarkers in demented and nondemented elderly subjects.

  8. Cdc42 inhibitor ML141 enhances G-CSF-induced hematopoietic stem and progenitor cell mobilization.

    Chen, Chong; Song, Xuguang; Ma, Sha; Wang, Xue; Xu, Jie; Zhang, Huanxin; Wu, Qingyun; Zhao, Kai; Cao, Jiang; Qiao, Jianlin; Sun, Xiaoshen; Li, Depeng; Zeng, Lingyu; Li, Zhengyu; Xu, Kailin


    G-CSF is the most often used agent in clinical hematopoietic stem and progenitor cell (HSPC) mobilization. However, in about 10 % of patients, G-CSF does not efficiently mobilize HSPC in clinically sufficient amounts. Cdc42 activity is involved in HSPC mobilization. In the present study, we explore the impact of Cdc42 inhibitor ML141 on G-CSF-mediated HSPC mobilization in mice. We found that the use of ML141 alone only triggered modest HSPC mobilization effect in mice. However, combination of G-CSF and ML141 significantly promoted HPSC counts and colony forming units in peripheral blood, as compared to mice treated with G-CSF alone. ML141 did not significantly alter the levels of SDF-1 and MMP-9 in the bone marrow, when used alone or in combination with G-CSF. We also found that G-CSF administration significantly increases the level of GTP-bound Cdc42, but does not alter the expression of Cdc42 in the bone marrow. Our data indicate that the Cdc42 signal is a negative regulator in G-CSF-mediated HSPC mobilization, and that inhibition of the Cdc42 signal efficiently improves mobilization efficiency. These findings may provide a new strategy for efficient HSPC mobilization, especially in patients with poor G-CSF response.

  10. CSF Flow in the Brain in the Context of Normal Pressure Hydrocephalus.

    Bradley, W G


    CSF normally flows back and forth through the aqueduct during the cardiac cycle. During systole, the brain and intracranial vasculature expand and compress the lateral and third ventricles, forcing CSF craniocaudad. During diastole, they contract and flow through the aqueduct reverses. Hyperdynamic CSF flow through the aqueduct is seen when there is ventricular enlargement without cerebral atrophy. Therefore, patients presenting with clinical normal pressure hydrocephalus who have hyperdynamic CSF flow have been found to respond better to ventriculoperitoneal shunting than those with normal or decreased CSF flow. Patients with normal pressure hydrocephalus have also been found to have larger intracranial volumes than sex-matched controls, suggesting that they may have had benign external hydrocephalus as infants. While their arachnoidal granulations clearly have decreased CSF resorptive capacity, it now appears that this is fixed and that the arachnoidal granulations are not merely immature. Such patients appear to develop a parallel pathway for CSF to exit the ventricles through the extracellular space of the brain and the venous side of the glymphatic system. This pathway remains functional until late adulthood when the patient develops deep white matter ischemia, which is characterized histologically by myelin pallor (ie, loss of lipid). The attraction between the bare myelin protein and the CSF increases resistance to the extracellular outflow of CSF, causing it to back up, resulting in hydrocephalus. Thus idiopathic normal pressure hydrocephalus appears to be a "2 hit" disease: benign external hydrocephalus in infancy followed by deep white matter ischemia in late adulthood.

  11. Analysis of the GM-CSF and GM-CSF/IL-3/IL-5 receptor common beta chain in a patient with pulmonary alveolar proteinosis


    Objective To investigate the expression of the granulocyte-macrophage colony-stimulating factor (GM-CSF) and GM-CSF/IL-3/IL-5 receptor common beta chain (βc receptor) in an adult patient with idiopathic pulmonary alveolar proteinosis (PAP), so as to demonstrate the possible association of the GM-CSF and βc receptor with the pathogenesis of human PAP. Methods The GM-CSF levels were measured with a commercial ELISA kit (sensitivity 5?pg/ml) and the βc receptor expression on the cell surface was detected by flow cytometry analysis. Reverse transcription-polymerase chain reaction (RT-PCR) analysis was employed to detect the expression of the GM-CSF mRNA and the βc receptor mRNA in peripheral blood mononuclear cells and alveolar macrophages. The entire coding regions of the GM-CSF cDNA and the βc receptor cDNA were sequenced by the Sanger dideoxy-mediated chain termination method to detect possible mutations. Results The patient with PAP failed to release the GM-CSF protein either from circulating mononuclear cells or from alveolar macrophages. The expression of the GM-CSF mRNA was normal after the stimulation of lipopolysaccharide, whereas a point mutation at position 382 of the GM-CSF cDNA from “T" to “C" was revealed by cDNA sequencing, which caused a change in amino acid 117 of the protein from isoleucine to threonine. The βc receptor expression on the cell surface was normal, and the βc receptor mRNA expression and the sequence of the entire coding region of the βc receptor were also normal. Conclusions The decreased GM-CSF production is associated with the pathogenesis of human PAP. A point mutation of the GM-CSF cDNA may contribute to the decreased GM-CSF production in our adult PAP patient. The mutation of the βc receptor in some of paediatric patients with PAP may not be a common problem in adult patients.

  12. MUNI-FITS-Utils

    Chrastina, M.; Zejda, M.; Mikulášek, Z.


    The FITS standard allows arbitrary use of name-space for keywords, except some reserved keywords. Result of this freedom is that several keywords have the same meaning. Similar problem is that values of keywords have different physical units. These facts complicate automated data processing and also creation of FITS file archives with simple structure. MUNI-FITS-Utils is a package of Python scripts which have been developed in PyFITS, a Python FITS Module. Scripts are user-friendly and allow manipulating FITS headers to get uniform shape. Further functions will be added soon.

    Sánchez, S. F.; Pérez, E.; Sánchez-Blázquez, P.; González, J. J.; Rosales-Ortega, F. F.; Cano-Díaz, M.; López-Cobá, C.; Marino, R. A.; Gil de Paz, A.; Mollá, M.; López-Sánchez, A. R.; Ascasibar, Y.; Barrera-Ballesteros, J.


    FIT3D fits optical spectra to deblend the underlying stellar population and the ionized gas, and extract physical information from each component. FIT3D is focused on the analysis of Integral Field Spectroscopy data, but is not restricted to it, and is the basis of Pipe3D, a pipeline used in the analysis of datasets like CALIFA, MaNGA, and SAMI. It can run iteratively or in an automatic way to derive the parameters of a large set of spectra.

  14. Reducing CSF shunt placement in patients with spinal myelomeningocele

    Suresh Sankhla


    Full Text Available Object: The incidence of hydrocephalus requiring shunts in children with myelomeningocele (MMC is reported to be very high. Shunt-related complications are a significant cause of morbidity and mortality in this population. In order to minimize shunt placements, we used very rigid clinical selection criteria and followed them in all patients who had myelomeningocele and enlarged ventricles. The follow-up outcome of this retrospective study is reported. Methods: From 2000 to 2007, 23 patients with myelomeningocele and variable degree of hydrocephalus were treated at our institute with primary surgical closure of their myelomeningoceles without a CSF diversion procedure. Patients with severe hydrocephalus who required immediate shunt insertion, and those with no significant associated hydrocephalus were not included in this study. Data regarding the surgical results and complications, postoperative management, and the outcome at follow-up were obtained from their hospital records. Results: Initially increased size of the ventricular system was found to have decreased or stabilized in 17 (81% patients postoperatively. However, ventriculomegaly continued to progress further in 4 (19% out of 21 patients. Of 11 patients who presented with enlarged head, eight (73% patients showed reduction or stabilization in their head circumference. Three (27% children continued to have progressive head enlargement in the postoperative period and required shunt placement. Signs of raised intracranial pressure observed in six patients on admission, improved in two (33% and persisted or worsened in four (67% patients who eventually improved after the insertion of a shunt. Eight (35% patients experienced wound-related complications following closure of the MMC, including CSF leak in four, wound infection in three, wound breakdown in three, and pseudomeningocele in two patients. Shunt placement was required in the postoperative period in 13 (56.5% patients to treat

  15. Soldier detection using unattended acoustic and seismic sensors

    Naz, P.; Hengy, S.; Hamery, P.


    During recent military conflicts, as well as for security interventions, the urban zone has taken a preponderant place. Studies have been initiated in national and in international programs to stimulate the technical innovations for these specific scenarios. For example joint field experiments have been organized by the NATO group SET-142 to evaluate the capability for the detection and localization of snipers, mortars or artillery guns using acoustic devices. Another important operational need corresponds to the protection of military sites or buildings. In this context, unattended acoustic and seismic sensors are envisaged to contribute to the survey of specific points by the detection of approaching enemy soldiers. This paper describes some measurements done in an anechoic chamber and in free field to characterize typical sounds generated by the soldier activities (walking, crawling, weapon handling, radio communication, clothing noises...). Footstep, speech and some specific impulsive sounds are detectable at various distances from the source. Such detection algorithms may be easily merged with the existing weapon firing detection algorithms to provide a more generic "battlefield acoustic" early warning system. Results obtained in various conditions (grassy terrain, gravel path, road, forest) will be presented. A method to extrapolate the distances of detection has been developed, based on an acoustic propagation model and applied to the laboratory measurements.

  16. Human performance modeling for system of systems analytics :soldier fatigue.

    Lawton, Craig R.; Campbell, James E.; Miller, Dwight Peter


    The military has identified Human Performance Modeling (HPM) as a significant requirement and challenge of future systems modeling and analysis initiatives as can be seen in the Department of Defense's (DoD) Defense Modeling and Simulation Office's (DMSO) Master Plan (DoD 5000.59-P 1995). To this goal, the military is currently spending millions of dollars on programs devoted to HPM in various military contexts. Examples include the Human Performance Modeling Integration (HPMI) program within the Air Force Research Laboratory, which focuses on integrating HPMs with constructive models of systems (e.g. cockpit simulations) and the Navy's Human Performance Center (HPC) established in September 2003. Nearly all of these initiatives focus on the interface between humans and a single system. This is insufficient in the era of highly complex network centric SoS. This report presents research and development in the area of HPM in a system-of-systems (SoS). Specifically, this report addresses modeling soldier fatigue and the potential impacts soldier fatigue can have on SoS performance.

  18. MafB antagonizes phenotypic alteration induced by GM-CSF in microglia

    Koshida, Ryusuke, E-mail:; Oishi, Hisashi, E-mail:; Hamada, Michito; Takahashi, Satoru


    Microglia are tissue-resident macrophages which are distributed throughout the central nervous system (CNS). Recent studies suggest that microglia are a unique myeloid population distinct from peripheral macrophages in terms of origin and gene expression signature. Granulocyte-macrophage colony-stimulating factor (GM-CSF), a pleiotropic cytokine regulating myeloid development, has been shown to stimulate proliferation and alter phenotype of microglia in vitro. However, how its signaling is modulated in microglia is poorly characterized. MafB, a bZip transcriptional factor, is highly expressed in monocyte-macrophage lineage cells including microglia, although its role in microglia is largely unknown. We investigated the crosstalk between GM-CSF signaling and MafB by analyzing primary microglia. We found that Mafb-deficient microglia grew more rapidly than wild-type microglia in response to GM-CSF. Moreover, the expression of genes associated with microglial differentiation was more downregulated in Mafb-deficient microglia cultured with GM-CSF. Notably, such differences between the genotypes were not observed in the presence of M-CSF. In addition, we found that Mafb-deficient microglia cultured with GM-CSF barely extended their membrane protrusions, probably due to abnormal activation of RhoA, a key regulator of cytoskeletal remodeling. Altogether, our study reveals that MafB is a negative regulator of GM-CSF signaling in microglia. These findings could provide new insight into the modulation of cytokine signaling by transcription factors in microglia. - Highlights: • GM-CSF alters the phenotype of microglia in vitro more potently than M-CSF. • Transcription factor MafB antagonizes the effect of GM-CSF on microglia in vitro. • MafB deficiency leads to RhoA activation in microglia in response to GM-CSF. • We show for the first time the function of MafB in microglia.

  19. Evaluation of prostaglandin D2 as a CSF leak marker: implications in safe epidural anesthesia

    Kondabolu S


    Full Text Available Sirish Kondabolu, Rishimani Adsumelli, Joy Schabel, Peter Glass, Srinivas PentyalaDepartment of Anesthesiology, School of Medicine, Stony Brook Medical Center, Stony Brook, New York, USABackground: It is accepted that there is a severe risk of dural puncture in epidural anesthesia. Of major concern to anesthesiologists is unintentional spinal block. Reliable identification of cerebrospinal fluid (CSF from the aspirate is crucial for safe epidural anesthesia. The aim of this study was to determine whether prostaglandin D2 could be clinically used as a marker for the detection of CSF traces.Methods: After obtaining Institutional Review Board approval and patient consent, CSF was obtained from patients undergoing spinal anesthesia, and blood, urine, and saliva were obtained from normal subjects and analyzed for prostaglandin D2 (PGD. CSF (n=5 samples were diluted with local anesthetic (bupivacaine, normal saline and blood in the ratios of 1:5 and 1:10. PGD levels in the CSF samples were analyzed with a PGD-Methoxime (MOX EIA Kit (Cayman Chemicals, MI. This assay is based on the conversion of PGD to a stable derivative, which is analyzed with antiserum specific for PGD-MOX. Results: Different concentrations of pure PGD-MOX conjugate were analyzed by EIA and a standard curve was derived. PGD levels in CSF and CSF with diluents were determined and the values were extrapolated onto the standard curve. Our results show a well-defined correlation for the presence of PGD both in straight CSF samples and in diluted CSF (dilution factor of 1:5 and 1:10. Conclusion: Prostaglandin D2 was reliably identified in CSF by enzyme-linked immunosorbent assay when diluted with local anesthetic, saline, and serum, and can be used as a marker to identify the presence of CSF in epidural aspirates.Keywords: epidural, cerebrospinal fluid, leak, marker, prostaglandin D2

    Yongming Cai; Zhengmin Chen; Ling Jiang; Ming Li; Changxiao Liu


    OBJECTIVE To compare the pharmacokinetics and pharmacodynamics of PEG30-rhG-CSF administered to beagle dogs at three different dosages with PEG20-rhG-CSF administered at one dosage,and to provide an experimental basis for clinical trials.METHODS Beagle dogs received single,subcutaneous doses of PEG30-rhG-CSF at 100,200 and 400 μg/kg or PEG20-rhG-CSF at 200 μg/kg.PEG30-rhG-CSF and PEG20-rhG-CSF concentrations in serum were analyzed using an enzyme-linked immunosorbent assay (ELISA).WBC,ANC and PLT counts of whole blood samples were measured using fully automated analytic instrumentation.Pharmacokinetic and pharmacodynamic parameters were calculated using DAS 2.0 statistical analysis software.RESULTS The pharmacokinetic parameters of PEG30-rhG-CSF calculated from the serum concentration data determined by ELISA were as follows:the mean elimination half-life (t1/2ke) was 40.6 h (33.5~45.4 h);the mean time to reach peak concentration (Tmax) was 19.2 h (11.7~24.0 h);the drug clearance from the serum (CL) was decreased with increasing doses:the peak concentration (Cmax) and the area under the serum concentration-time curve (AUC) were increased with increasing doses.For PEG20-rhG-CSF,the half-life was shorter (12 h) and Tmax was achieved much earlier (10 h) relative to PEG30-rhG-CSF.The AUC of PEG30-rhG-CSF was much greater than that of PEG20-rhG-CSF,and the relative bioavailability with a subcutaneous injection was 158.7%.Administration of single doses of PEG30-rhG-CSF resulted in substantial increases in the absolute neutrophil count (ANC).The time to reach ANCmax (ANCTmax) was 72 h.The maximum observed absolute neutrophil counts (ANCmax) and the area over the baseline effect curve (AOBEC) was increased with increasing doses.The effect-elimination half-life (t1/2E) ranged from 60 h to 80 h after subcutaneous administration.The PLT count was slightly elevated 8-12 h after s.c.injection,and declined after 24 h.CONCLUSION The mean elimination half-life of PEG30-rhG-CSF

  1. Proximal Limb Weakness Reverting After CSF Diversion In Intracranial Hypertension

    Sinha S


    Full Text Available We report about two young girls who developed progressive visual failure secondary to increased intracranial pressure and had significant proximal muscle weakness of limbs. Patients with elevated intracranial pressure (ICP may present with "false localizing signs", besides having headache, vomiting and papilledema. Radicular pain as a manifestation of raised ICP is rare and motor weakness attributable to polyradiculopathy is exceptional. Two patients with increased intracranial pressure without lateralizing signs′ had singnificant muscle weakness. Clinical evaluation and laboratory tests did not disclose any other cause for weakness. Following theco-peritoneal shunt, in both patients, there was variable recovery of vision but the proximal weakness and symptoms of elevated ICP improved rapidly. Recognition of this uncommon manifestation of raised ICP may obviate the need for unnecessary investigation and reduce morbidity due to weakness by CSF diversion procedure.

  2. Routine CSF analysis in coccidioidomycosis is not required.

    George Thompson

    Full Text Available Although routinely done, there has been no evaluation of the utility of performing routine cerebrospinal fluid (CSF examination in patients with active coccidioidomycosis and high complement fixation (IgG antibody titers or other risk factors for disseminated infection. In our review 100% of patients diagnosed with coccidioidal meningitis had at least one sign or symptom consistent with infection of the central nervous system, headache was present in 100% of those with meningitis, while no patients without signs/symptoms of CNS infection were found to have coccidioidal meningitis, irrespective of antibody titers or other risk factors. Thus routine lumbar puncture may be unnecessary for patients with coccidioidomycosis who lack suggestive clinical symptoms.

  3. Increased CSF levels of endorphines in chronic psychosis.

    Terenius, L; Wahlström, A; Lindström, L; Widerlöv, E


    The levels of two endorphines, endogenously occurring morphinomimetic peptides, were measured in serial samples of CSF from seven psychiatric patients. Four cases with chronic schizophrenia were studied before and after treatment with the antipsychotic agent clozapine (Leponex). Supernormal fraction II levels were found on at least one sampling occasion in each patient. Two patients, who responded well to clozapine treatment, showed a clear-cut drop in fraction II levels, whereas two patients showed increased levels which paralleled a deterioration of the schizophrenic symptoms. Three manic-depressive cases showed abnormally high levels of endorphine fraction I in the manic phase which declined during normal or depressed phases. Levels of fraction II varied in a less consistent manner and appeared to be at maximum during the apparently normal phases. Although preliminary, the data indicate that endorphines may reach supernormal levels in patients with chronic psychoses.

  4. Chimeric classical swine fever (CSF)-Japanese encephalitis (JE) viral replicon as a non-transmissible vaccine candidate against CSF and JE infections.

    Yang, Zhenhua; Wu, Rui; Li, Robert W; Li, Ling; Xiong, Zhongliang; Zhao, Haizhong; Guo, Deyin; Pan, Zishu


    A trans-complemented chimeric CSF-JE virus replicon was constructed using an infectious cDNA clone of the CSF virus (CSFV) Alfort/187 strain. The CSFV E2 gene was deleted, and a fragment containing the region encoding a truncated envelope protein (tE, amino acid 292-402, domain III) of JE virus (JEV) was inserted into the resultant plasmid, pA187delE2, to generate the recombinant cDNA clone pA187delE2/JEV-tE. Porcine kidney 15 (PK15) cells that constitutively express the CSFV E2p7 proteins were then transfected with in vitro-transcribed RNA from pA187delE2/JEV-tE. As a result, the chimeric CSF-JE virus replicon particle (VRP), rv187delE2/JEV-tE, was rescued. In a mouse model, immunization with the chimeric CSF-JE VRP induced strong production of JEV-specific antibody and conferred protection against a lethal JEV challenge. Pigs immunized with CSF-JE VRP displayed strong anti-CSFV and anti-JEV antibody responses and protection against CSFV and JEV challenge infections. Our evidence suggests that E2-complemented CSF-JE VRP not only has potential as a live-attenuated non-transmissible vaccine candidate against CSF and JE but also serves as a potential DIVA (Differentiating Infected from Vaccinated Animals) vaccine for CSF in pigs. Together, our data suggest that the non-transmissible chimeric VRP expressing foreign antigenic proteins may represent a promising strategy for bivalent DIVA vaccine design.

Conclusions:The somatotype characteristic of men soldier in mobile troops is skeletal muscle to become de-veloped, body to become muscular, somatotype type to concentrate main middle embryonic type.

  6. Are injuries from terror and war similar? A comparison study of civilians and soldiers.

    Peleg, Kobi; Jaffe, Dena H


    To compare injuries and hospital utilization and outcomes from terror and war for civilians and soldiers. Injuries from terror and war are not necessarily comparable, especially among civilians and soldiers. For example, civilians have less direct exposure to conflict and are unprepared for injury, whereas soldiers are psychologically and physically prepared for combat on battlefields that are often far from trauma centers. Evidence-based studies distinguishing and characterizing differences in injuries according to conflict type and population group are lacking. A retrospective study was performed using hospitalization data from the Israel National Trauma Registry (10/2000-12/2006). Terror and war accounted for trauma hospitalizations among 1784 civilians and 802 soldiers. Most civilians (93%) were injured in terror and transferred to trauma centers by land, whereas soldiers were transferred by land and air. Critical injuries and injuries to multiple body regions were more likely in terror than war. Soldiers tended to present with less severe injuries from war than from terror. Rates of first admission to orthopedic surgery were greater for all casualties with the exception of civilians injured in terror who were equally likely to be admitted to the intensive care unit. In-hospital mortality was higher among terror (7%) than war (2%) casualties, and particularly among civilians. This study provides evidence that substantial differences exist in injury characteristics and hospital resources required to treat civilians and soldiers injured in terror and war. Hospital preparedness and management should focus on treating combat injuries that result from specific causes-terror or war.

    Taylor, Christine M; Ross, Michelle E; Wood, Joanne N; Griffis, Heather M; Harb, Gerlinde C; Mi, Lanyu; Song, Lihai; Strane, Douglas; Lynch, Kevin G; Rubin, David M


    We described the risk for maltreatment among toddlers of US Army soldiers over different deployment cycles to develop a systematic response within the US Army to provide families appropriate supports. We conducted a person-time analysis of substantiated maltreatment reports and medical diagnoses among children of 112,325 deployed US Army soldiers between 2001 and 2007. Risk of maltreatment was elevated after deployment for children of soldiers deployed once but not for children of soldiers deployed twice. During the 6 months after deployment, children of soldiers deployed once had 4.43 substantiated maltreatment reports and 4.96 medical diagnoses per 10,000 child-months. The highest maltreatment rate among children of soldiers deployed twice occurred during the second deployment for substantiated maltreatment (4.83 episodes per 10,000 child-months) and before the first deployment for medical diagnoses of maltreatment (3.78 episodes per 10,000 child-months). We confirmed an elevated risk for child maltreatment during deployment but also found a previously unidentified high-risk period during the 6 months following deployment, indicating elevated stress within families of deployed and returning soldiers. These findings can inform efforts by the military to initiate and standardize support and preparation to families during periods of elevated risk.

  8. CSF metabolic and proteomic profiles in patients prodromal for psychosis.

    Jeffrey T-J Huang

    Full Text Available BACKGROUND: The initial prodromal state of psychosis (IPS is defined as an early disease stage prior to the onset of overt psychosis characterized by sub-threshold or more unspecific psychiatric symptoms. Little is known regarding the biochemical changes during this period. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the metabolic/proteomic profiles of cerebrospinal fluid (CSF of first-onset drug naïve paranoid schizophrenia patients (n = 54 and individuals presenting with initial prodromal symptoms (n = 24, alongside healthy volunteers (n = 70 using proton nuclear magnetic resonance ((1H-NMR spectroscopy and surface enhanced laser desorption ionization (SELDI mass spectrometry, respectively. Partial least square discriminant analysis (PLS-DA showed that 36%/29% of IPS patients displayed proteomic/metabolic profiles characteristic of first-onset, drug naïve schizophrenia, i.e., changes in levels of glucose and lactate as well as changes in a VGF-derived peptide (VGF23-62 and transthyretin protein concentrations. However, only 29% (n = 7 of the investigated IPS patients (who to date have been followed up for up to three years have so far received a diagnosis of schizophrenia. The presence of biochemical alterations in the IPS group did not correlate with the risk to develop schizophrenia. CONCLUSIONS/SIGNIFICANCE: Our results imply that schizophrenia-related biochemical disease processes can be traced in CSF of prodromal patients. However, the biochemical disturbances identified in IPS patients, at least when measured at a single time point, may not be sufficient to predict clinical outcome.

  9. Paediatric Crohn disease patients with stricturing behaviour exhibit ileal granulocyte–macrophage colony-stimulating factor (GM-CSF) autoantibody production and reduced neutrophil bacterial killing and GM-CSF bioactivity

    Jurickova, I; Collins, M H; Chalk, C; Seese, A; Bezold, R; Lake, K; Allmen, D; Frischer, J S; Falcone, R A; Trapnell, B C; Denson, L A


    Granulocyte–macrophage colony-stimulating factor (GM-CSF) autoantibodies are associated with stricturing behaviour in Crohn disease (CD). We hypothesized that CD ileal lamina propria mononuclear cells (LPMC) would produce GM-CSF autoantibodies and peripheral blood (PB) samples would contain GM-CSF neutralizing capacity (NC). Paediatric CD and control PBMC and ileal biopsies or LPMC were isolated and cultured and GM-CSF, immunoglobulin (Ig)G and GM-CSF autoantibodies production were measured by enzyme-linked immunosorbent assay (ELISA). Basal and GM-CSF-primed neutrophil bacterial killing and signal transducer and activator of transcription 5 (STAT5) tyrosine phosphorylation (pSTAT5) were measured by flow cytometry. GM-CSF autoantibodies were enriched within total IgG for LPMC isolated from CD ileal strictures and proximal margins compared to control ileum. Neutrophil bacterial killing was reduced in CD patients compared to controls. Within CD, neutrophil GM-CSF-dependent STAT5 activation and bacterial killing were reduced as GM-CSF autoantibodies increased. GM-CSF stimulation of pSTAT5 did not vary between controls and CD patients in washed PB granulocytes in which serum was removed. However, GM-CSF stimulation of pSTAT5 was reduced in whole PB samples from CD patients. These data were used to calculate the GM-CSF NC. CD patients with GM-CSF NC greater than 25% exhibited a fourfold higher rate of stricturing behaviour and surgery. The likelihood ratio (95% confidence interval) for stricturing behaviour for patients with elevation in both GM-CSF autoantibodies and GM-CSF NC was equal to 5 (2, 11). GM-CSF autoantibodies are produced by LPMC isolated from CD ileal resection specimens and are associated with reduced neutrophil bacterial killing. CD peripheral blood contains GM-CSF NC, which is associated with increased rates of stricturing behaviour. PMID:23600834

  10. G-CSF plus preemptive plerixafor vs hyperfractionated CY plus G-CSF for autologous stem cell mobilization in multiple myeloma: effectiveness, safety and cost analysis.

    Antar, A; Otrock, Z K; Kharfan-Dabaja, M A; Ghaddara, H A; Kreidieh, N; Mahfouz, R; Bazarbachi, A


    The optimal stem cell mobilization regimen for patients with multiple myeloma (MM) remains undefined. We retrospectively compared our experience in hematopoietic cell mobilization in 83 MM patients using fractionated high-dose CY and G-CSF with G-CSF plus preemptive plerixafor. All patients in the CY group (n=56) received fractionated high-dose CY (5 g/m(2) divided into five doses of 1 g/m(2) every 3 h) with G-CSF. All patients in the plerixafor group (n=27) received G-CSF and plerixafor preemptively based on an established algorithm. Compared with plerixafor, CY use was associated with higher total CD34+ cell yield (7.5 × 10(6) vs 15.5 × 10(6) cells/kg, P=0.005). All patients in both groups yielded ⩾4 × 10(6) CD34+ cells/kg. Conversely, CY use was associated with high frequency of febrile neutropenia, blood and platelet transfusions need and hospitalizations. The average total cost of mobilization in Lebanon was slightly higher in the plerixafor group ($7886 vs $7536; P=0.16). Our data indicate robust stem cell mobilization in MM patients with either fractionated high-dose CY and G-CSF or G-CSF alone with preemptive plerixafor. The chemo-mobilization approach was associated with twofold stem cell yield, slightly lower cost but significantly increased toxicity.

  11. G-CSF preferentially supports the generation of gut-homing Gr-1high macrophages in M-CSF-treated bone marrow cells.

    Meshkibaf, Shahab; Gower, Mark William; Dekaban, Gregory A; Kim, Sung Ouk


    The G-CSF is best known for its activity in the generation and activation of neutrophils. In addition, studies on G-CSF(-/-) or G-CSFR(-/-) mice and BMC cultures suggested a role of G-CSF in macrophage generation. However, our understanding on the role of G-CSF in macrophage development is limited. Here, using in vitro BMC models, we demonstrated that G-CSF promoted the generation of Gr-1(high)/F4/80(+) macrophage-like cells in M-BMCs, likely through suppressing cell death and enhancing generation of Gr-1(high)/F4/80(+) macrophage-like cells. These Gr-1(high) macrophage-like cells produced "M2-like" cytokines and surface markers in response to LPS and IL-4/IL-13, respectively. Adoptive transfer of EGFP-expressing (EGFP(+)) M-BMCs showed a dominant, gut-homing phenotype. The small intestinal lamina propria of G-CSFR(-/-) mice also harbored significantly reduced numbers of Gr-1(high)/F4/80(+) macrophages compared with those of WT mice, but levels of Gr-1(+)/F4/80(-) neutrophil-like cells were similar between these mice. Collectively, these results suggest a novel function of G-CSF in the generation of gut-homing, M2-like macrophages.

  12. CSF alpha-synuclein does not discriminate dementia with lewy bodies from Alzheimer's disease.

    Reesink, F.E.; Lemstra, A.W.; Dijk, K.D. van; Berendse, H.W.; Berg, W.D. van de; Klein, M.; Blankenstein, M.A.; Scheltens, P.; Verbeek, M.M.; Flier, W.M. van der


    In this study, we assessed whether cerebrospinal fluid (CSF) levels of the biomarker alpha-synuclein have a diagnostic value in differential diagnosis of dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). We also analyzed associations between CSF biomarkers and cognitive performance in DL

  13. Do CSF Biomarkers Predict Progression to Cognitive Impairment in Parkinson's disease patients? A Systematic Review.

    Leaver, Katherine; Poston, Kathleen L


    Many patients with Parkinson's disease (PD) will develop cognitive impairment. Cross-sectional studies have shown that certain protein levels are altered in the cerebrospinal fluid (CSF) of PD patients with dementia and are thought to represent potential biomarkers of underlying pathogenesis. Recent studies suggest that CSF biomarker levels may be predictive of future risk of cognitive decline in non-demented PD patients. However, the strength of this evidence and difference between specific CSF biomarkers is not well delineated. We therefore performed a systematic review to assess if levels of specific CSF protein biomarkers are predictive of progression to cognitive impairment. Nine articles were identified that met inclusion criteria for the review. Findings from the review suggest a convergence of evidence that a low baseline Aβ42 in the CSF of non-demented PD patients predicts development of cognitive impairment over time. Conversely, there is limited evidence that CSF levels of tau, either total tau or phosphorylated tau, is a useful predictive biomarker. There are mixed results for other CSF biomarkers such as α-synuclein, Neurofilament light chain, and Heart fatty acid-binding protein. Overall the results of this review show that certain CSF biomarkers have better predictive ability to identify PD patients who are at risk for developing cognitive impairment. Given the interest in developing disease-modifying therapies, identifying this group will be important for clinical trials as initiation of therapy prior to the onset of cognitive decline is likely to be more efficacious.

  14. Sunlight triggers cutaneous lupus through a CSF-1-dependent mechanism in MRL-Fas(lpr) mice.

    Menke, Julia; Hsu, Mei-Yu; Byrne, Katelyn T; Lucas, Julie A; Rabacal, Whitney A; Croker, Byron P; Zong, Xiao-Hua; Stanley, E Richard; Kelley, Vicki R


    Sunlight (UVB) triggers cutaneous lupus erythematosus (CLE) and systemic lupus through an unknown mechanism. We tested the hypothesis that UVB triggers CLE through a CSF-1-dependent, macrophage (Mø)-mediated mechanism in MRL-Fas(lpr) mice. By constructing mutant MRL-Fas(lpr) strains expressing varying levels of CSF-1 (high, intermediate, none), and use of an ex vivo gene transfer to deliver CSF-1 intradermally, we determined that CSF-1 induces CLE in lupus-susceptible MRL-Fas(lpr) mice, but not in lupus-resistant BALB/c mice. UVB incites an increase in Møs, apoptosis in the skin, and CLE in MRL-Fas(lpr), but not in CSF-1-deficient MRL-Fas(lpr) mice. Furthermore, UVB did not induce CLE in BALB/c mice. Probing further, UVB stimulates CSF-1 expression by keratinocytes leading to recruitment and activation of Møs that, in turn, release mediators, which induce apoptosis in keratinocytes. Thus, sunlight triggers a CSF-1-dependent, Mø-mediated destructive inflammation in the skin leading to CLE in lupus-susceptible MRL-Fas(lpr) but not lupus-resistant BALB/c mice. Taken together, CSF-1 is envisioned as the match and lupus susceptibility as the tinder leading to CLE.

  15. Benign meningioma metastasizing through CSF pathways : a case report and review of literature.

    Ramakrishnamurthy T


    Full Text Available Metastasis of intraventricular meningiomas through CSF pathways is a rarity and only 4 cases have been reported in world literature describing meningiomas which were intraventricular and malignant. Here we report a case of benign intraventricular meningioma which had spread through CSF pathways, the recurrences as well as the primary tumor being benign in nature.

  16. Increased CSF alpha-synuclein levels in Alzheimer's disease : Correlation with tau levels

    Slaets, Sylvie; Vanmechelen, Eugeen; Le Bastard, Nathalie; Decraemer, Hilde; Vandijck, Manu; Martin, Jean-Jacques; De Deyn, Peter Paul; Engelborghs, Sebastiaan


    Background: Given the difficult clinical differential diagnosis between Alzheimer's disease (AD) and dementia with Lewy bodies (DLB), growing interest resulted in research on alpha-synuclein as a potential cerebrospinal fluid biomarker (CSF) for synucleinopathies. Methods: CSF alpha-synuclein-140 co

  17. Proteomic investigations of the ventriculo-lumbar gradient in human CSF

    Simonsen, Anja Hviid; Bech, Sara Brynhild Winther; Laursen, Inga


    Cerebrospinal fluid (CSF) is an ideal biological material in which to search for new biomarkers for improved diagnosis of neurological diseases. During a lumbar puncture between 5 and 15 mL of CSF are obtained. Previous studies have assessed the ventriculo-lumbar concentration gradient of a number...

  18. G-CSF for mobilizing transplanted bone marrow stem cells in rat model of Parkinson's disease.

    Safari, Manouchehr; Jafari, Behnaz; Zarbakhsh, Sam; Sameni, Hamidreza; Vafaei, Abbas Ali; Mohammadi, Nasrin Khan; Ghahari, Laya


    Granulocyte-colony stimulating factor (G-CSF) is used in clinical practice for the treatment of neutropenia and to stimulate generation of hematopoietic stem cells in bone marrow donors. In the present study, the ability of G-CSF in mobilizing exogenous bone marrow stem cells (BMSCs) from peripheral blood into the brain was tested. We for the first time injected a small amount of BMSCs through the tail vein. We choose 25 male Wistar rats (200-250 g) were lesioned by 6-OHDA injected into the left substantia nigra, pars compacta (SNpc). G-CSF (70 µg/kg/day) was given from the 7(th) day after lesion for five days. The BMSCs (2×10(5)) were injected through the dorsal tail vein on the 7(th) day after lesion. The number of rotations was significantly lower in the stem cell therapy group than in the control group. In the third test in the received G-CSF and G-CSF+stem cells groups, animals displayed significant behavioral recovery compared with the control group (Pstem cells groups. We didn't detect any labeling stem cells in SNpc. G-CSF can't mobilize low amounts of exogenous BMSCs from the blood stream to injured SNpc. But G-CSF (70 µg/kg) is more neuroprotective than BMSCs (2×10(5) number[w1] of BMSCs). Results of our study suggest that G-CSF alone is more neuroprotective than BMSCs.

  19. T2-weighted vs. intrathecal contrast-enhanced MR cisternography in the evaluation of CSF rhinorrhea

    Ecin, Gaye; Oner, A. Yusuf; Tokgoz, Nil; Ucar, Murat; Tali, Turgut [Dept. of Radiology, Gazi Univ. School of Medicine, Ankara (Turkey)], e-mail:; Aykol, Sukru [Dept. of Neurosurgery, Gazi Univ. School of Medicine, Ankara (Turkey)


    Background: Endoscopic surgical approach is being more widely used in the treatment of cerebrospinal fluid (CSF) rhinorrhea. Accurate localization of CSF fistulas prior to surgery is essential in increasing the success of dural repair and in decreasing negative or recurrent explorations. Purpose: To evaluate and compare intrathecal contrast medium-enhanced magnetic resonance cisternography (CEMRC) with T2-weighted MR cisternography (T2MRC) in identifying the presence and site of CSF rhinorrhea. Material and Methods: Sixty patients with suspected CSF rhinorrhea underwent MR cisternography including intrathecally enhanced fat-suppressed T1WI in three orthogonal planes and T2WI in the coronal plane. Both set of images were reviewed by two blinded radiologists for the presence and location of CSF leakage. Imaging data were compared with surgical findings and/or beta-2 transferrin testing. Results: With surgery proven CSF leakage in 20 instances as reference, CEMRC detected 18 (90%), whereas T2MRC reported only 13 (65%) correctly. Overall, sensitivity, specificity, positive predictive value, and negative predictive value in detecting CSF fistulas were 92%, 80%, 76%, and 93% for CEMRC, and 56%, 77%, 64%, and 71% for T2MRC, respectively. Conclusion: The minimally invasive CEMRC is an effective method with higher sensitivity and specificity than T2MRC in the evaluation of CSF fistulas.

    AIM: To evaluate the efficacy of granulocyte colony stimulating factors (G-CSF) in liver transplanted patients with hepatitis C (HCV) recurrence and Pegylated-IFN α-2b induced neutropenia, and to evaluate the impact of G-CSF administration on virological response.METHODS: Sixty-eight patients undergoing antiviral treatment for post-liver transplantation (OLT) HCV recurrence were enrolled.All patients developing neutropenia received G-CSF.RESULTS: Twenty three (34%) received G-CSF.Mean neutrophil count at the onset of neutropenia was 700/mmc (range 400-750/mmc); after 1 mo of G-CSF it increased to 1210/mmc (range 300-5590/mmc) ( P < 0.0001).Three patients did not respond to G-CSF.Treatment duration was similar in neutropenic and non-neutropenic patients.No differences in the rate of discontinuation, infections or virological response were observed between the two groups.G-CSF was protective for the onset of de novo autoimmune hepatitis ( P < 0.003).CONCLUSION: G-CSF administration is effective in the case of Peg-IFN induced neutropenia increasing neutrophil count, prolonging treatment and leading to sustained virological response (SVR) rates comparable to non-neutropenic patients.It prevents the occurrence of de novo autoimmune hepatitis.

  1. Issues in cerebrospinal fluid management. CSF Venereal Disease Research Laboratory testing.

    Albright, R E; Christenson, R H; Emlet, J L; Graham, C B; Estevez, E G; Wilson, M L; Reller, L B; Schneider, K A


    Three policies for decreasing unnecessary cerebrospinal fluid (CSF) management Venereal Disease Research Laboratory (VDRL) tests were compared. The first policy attempted to educate physicians about the use of serologic tests for diagnosing neurosyphilis but allowed the CSF VDRL to be performed either as a screening test or as a retrospective test. The second policy required that the CSF VDRL be performed as a retrospective test without regard to the patient's serologic status. The third policy required that a patient be seropositive by either rapid plasma reagin (RPR) or fluorescent treponemal antibody absorbance (FTA-ABS) before a CSF VDRL could be performed. Before these policies were instituted, VDRL testing was performed on 18.2% of all CSF samples. The optional and required retrospective policies decreased the CSF VDRL rate to 13.0% and 8.5%, respectively, but the percentages of seropositive patients for whom these procedures were performed were only 7.3% and 12.9%. The third policy decreased the CSF VDRL test rate to 1.8% (P less than 0.001) with seropositivity improving to 90%. To assure serologic tests are obtained in the evaluation of neurosyphilis, requirement for seropositivity must be implemented with the use of retrospective CSF VDRL testing.

  2. Cerebrospinal Fluid Biomarkers of Simian Immunodeficiency Virus Encephalitis : CSF Biomarkers of SIV Encephalitis.

    Bissel, Stephanie J; Kofler, Julia; Nyaundi, Julia; Murphey-Corb, Michael; Wisniewski, Stephen R; Wiley, Clayton A


    Antiretroviral therapy has led to increased survival of HIV-infected patients but also increased prevalence of HIV-associated neurocognitive disorders. We previously identified YKL40 as a potential cerebrospinal fluid (CSF) biomarker of lentiviral central nervous system (CNS) disease in HIV-infected patients and in the macaque model of HIV encephalitis. The aim of this study was to define the specificity and sensitivity along with the predictive value of YKL40 as a biomarker of encephalitis and to assess its relationship to CSF viral load. CSF YKL40 and SIV RNA concentrations were analyzed over the course of infection in 19 SIV-infected pigtailed macaques and statistical analyses were performed to evaluate the relationship to encephalitis. Using these relationships, CSF alterations of 31 neuroimmune markers were studied pre-infection, during acute and asymptomatic infection, at the onset of encephalitis, and at necropsy. YKL40 CSF concentrations above 1122 ng/ml were found to be a specific and sensitive biomarker for the presence of encephalitis and were highly correlated with CSF viral load. Macaques that developed encephalitis had evidence of chronic CNS immune activation during early, asymptomatic, and end stages of infection. At the onset of encephalitis, CSF demonstrated a rise of neuroimmune markers associated with macrophage recruitment, activation and interferon response. CSF YKL40 concentration and viral load are valuable biomarkers to define the onset of encephalitis. Chronic CNS immune activation precedes the development of encephalitis while some responses suggest protection from CNS lentiviral disease.

  3. Effects of CSF proteins on brain atrophy rates in cognitively healthy older adults

    Mattsson, Niklas; Insel, Philip; Nosheny, Rachel; Trojanowski, John Q.; Shaw, Leslie M.; Jack, Clifford R.; Tosun, Duygu; Weiner, Michael


    Biomarkers associated with Alzheimer’s disease (AD)-like brain atrophy in healthy people may identify mechanisms involved in early stage AD. Aside from cerebrospinal fluid (CSF) β-amyloid42 (Aβ42) and tau, no studies have tested associations between CSF proteins and AD-like brain atrophy. We studied 90 healthy elders, who underwent lumbar puncture at baseline, and serial magnetic resonance imaging scans for up to 4 years. We tested statistical effects of baseline CSF proteins (N=70 proteins related to Aβ42-metabolism, microglial activity and synaptic/neuronal function) on atrophy rates in 7 AD-related regions. Besides effects of Aβ42 and phosphorylated tau (P-tau) that were seen in several regions, novel CSF proteins were found to have effects in inferior and middle temporal cortex (including Apolipoprotein CIII, Apolipoprotein D and Apolipoprotein H). Several proteins (including S100β and Matrix Metalloproteinase-3) had effects that depended on the presence of brain Aβ pathology, as measured by CSF Aβ42. Other proteins (including P-tau and Apolipoprotein D) had effects even after adjusting for CSF Aβ42. The statistical effects in this exploratory study were mild and not significant after correction for multiple comparisons, but some of the identified proteins may be associated with brain atrophy in healthy people. Proteins interacting with CSF Aβ42 may be related to Aβ brain pathology, while proteins associated with atrophy even after adjusting for CSF Aβ42 may be related to Aβ-independent mechanisms.

  4. Quasispecies on Fitness Landscapes.

    Schuster, Peter


    Selection-mutation dynamics is studied as adaptation and neutral drift on abstract fitness landscapes. Various models of fitness landscapes are introduced and analyzed with respect to the stationary mutant distributions adopted by populations upon them. The concept of quasispecies is introduced, and the error threshold phenomenon is analyzed. Complex fitness landscapes with large scatter of fitness values are shown to sustain error thresholds. The phenomenological theory of the quasispecies introduced in 1971 by Eigen is compared to approximation-free numerical computations. The concept of strong quasispecies understood as mutant distributions, which are especially stable against changes in mutations rates, is presented. The role of fitness neutral genotypes in quasispecies is discussed.

  5. Interpersonal-Psychological Theory, Alexithymia, and Personality Predict Suicide Ideation among Maladjusted Soldiers in Taiwan.

    Huang, Kai-Cheng; Tzeng, Dong-Sheng; Lin, Chi-Hung; Chung, Wei-Ching


    This case-control study enrolled 226 maladjusted soldiers and 229 controls to investigate the impact of the interpersonal-psychological theory of suicide, alexithymia, personality, and childhood trauma on suicide risk among Taiwanese soldiers. Assessments included the Toronto Alexithymia Scale, Eysenck Personality Inventory, Mini-International Neuropsychiatric Interview, and Brief Symptom Rating Scale. In addition to thwarted belongingness and perceived burdensomeness, other risks included less extraversion with higher neuroticism, higher alexithymia, poor academic performance, domestic violence, and life-threatening events. Our study demonstrates the interaction of the interpersonal-psychological theory and other suicide risk factors in Taiwanese soldiers. © 2016 The American Association of Suicidology.

  6. Detection of Listeria monocytogenes in CSF from Three Patients with Meningoencephalitis by Next-Generation Sequencing

    Yao, Ming; Zhou, Jiali; Zhu, Yicheng; Zhang, Yinxin; Lv, Xia; Sun, Ruixue; Shen, Ao; Ren, Haitao; Cui, Liying


    Background and Purpose Encephalitis caused by Listeria monocytogenes (L. monocytogenes) is rare but sometimes fatal. Early diagnosis is difficult using routine cerebrospinal fluid (CSF) tests, while next-generation sequencing (NGS) is increasingly being used for the detection and characterization of pathogens. Methods This study set up and applied unbiased NGS to detect L. monocytogenes in CSF collected from three cases of clinically suspected listeria meningoencephalitis. Results Three cases of patients with acute/subacute meningoencephalitis are reported. Magnetic resonance imaging and blood cultures led to a suspected diagnosis of L. monocytogenes, while the CSF cultures were negative. Unbiased NGS of CSF identified and sequenced reads corresponding to L. monocytogenes in all three cases. Conclusions This is the first report highlighting the feasibility of applying NGS of CSF as a diagnostic method for central nervous system (CNS) L. monocytogenes infection. Routine application of this technology in clinical microbiology will significantly improve diagnostic methods for CNS infectious diseases.

  7. Persistent CSF Rhinorrhoea, Pneumocephalus, and Recurrent Meningitis Following Misdiagnosis of Olfactory Neuroblastoma

    Neil Barua


    Full Text Available A 41-year-old female patient was admitted with streptococcal meningitis on a background of 5-month history of CSF rhinorrhoea. Imaging revealed an extensive skull base lesion involving the sphenoid and ethmoid sinuses, the pituitary fossa with suprasellar extension and bony destruction. Histological examination of an endonasal transethmoidal biopsy suggested a diagnosis of olfactory neuroblastoma. A profuse CSF leak occurred and the patient developed coliform meningitis. A second endonasal endoscopic biopsy was undertaken which demonstrated the tumour to be a prolactinoma. Following endonasal repair of the CSF leak and lumbar drainage, she developed profound pneumocephalus. The patient underwent three further unsuccessful CSF leak repairs. Definitive control of the CSF leak was finally achieved through a transcranial approach with prolonged lumbar drainage. This case illustrates some of the potentially devastating complications which can occur as a consequence of complex skull base lesions. A multidisciplinary approach may be required to successfully manage such cases.

  8. Combinatorial G-CSF/AMD3100 treatment in cardiac repair after myocardial infarction.

    Constantin Rüder

    Full Text Available Several studies suggest that circulating bone marrow derived stem cells promote the regeneration of ischemic tissues. For hematopoietic stem cell transplantation combinatorial granulocyte-colony stimulating factor (G-CSF/Plerixafor (AMD3100 administration was shown to enhance mobilization of bone marrow derived stem cells compared to G-CSF monotherapy. Here we tested the hypothesis whether combinatorial G-CSF/AMD3100 therapy has beneficial effects in cardiac recovery in a mouse model of myocardial infarction.We analyzed the effect of single G-CSF (250 µg/kg/day and combinatorial G-CSF/AMD3100 (100 µg/kg/day treatment on cardiac morphology, vascularization, and hemodynamics 28 days after permanent ligation of the left anterior descending artery (LAD. G-CSF treatment started directly after induction of myocardial infarction (MI for 3 consecutive days followed by a single AMD3100 application on day three after MI in the G-CSF/AMD3100 group. Cell mobilization was assessed by flow cytometry of blood samples drawn from tail vein on day 0, 7, and 14.Peripheral blood analysis 7 days after MI showed enhanced mobilization of white blood cells (WBC and endothelial progenitor cells (EPC upon G-CSF and combinatorial G-CSF/AMD3100 treatment. However, single or combinatorial treatment showed no improvement in survival, left ventricular function, and infarction size compared to the saline treated control group 28 days after MI. Furthermore, no differences in histology and vascularization of infarcted hearts could be observed.Although the implemented treatment regimen caused no adverse effects, our data show that combinatorial G-CSF/AMD therapy does not promote myocardial regeneration after permanent LAD occlusion.

  9. CSF/serum quotient graphs for the evaluation of intrathecal C4 synthesis

    Rey Alexis


    Full Text Available Abstract Background Cerebrospinal fluid (CSF/serum quotient graphs have been used previously to determine local synthesis in brain of immunoglobulins and C3 complement component. The aim of this study was to use the same technique to construct quotient graphs, or Reibergrams, for the beta globulin C4 and to evaluate the method for assessing intrathecal synthesis in neurological disease. Methods The constants in the previously-defined Reibergram for immunoglobulin IgA were used to calculate the CSF/serum quotient for C4. CSF and serum were analyzed for C4, IgA and albumin from a total of 12 patients with meningoencephalitis caused by encapsulated microorganisms and 10 subjects without infections or inflammatory neurological disease, some of which had dysfunction of the blood-CSF barrier, Results The formula and C4 Reibergram with the constants previously found for IgA, determined the intrathecal C4 synthesis in CSF. The intrathecal C4 fraction in CSF (C4 loc in mg/l was compared to the C4-Index (fraction of CSF: serum for C 4/fraction of CSF: serum for albumin. There was a significant correlation between the two formulae. The CSF/Serum quotient graph was superior for detecting intrathecal synthesis of C4 under variable conditions of blood-CSF barrier permeability. Conclusion The C4 Reibergram can be used to quantify the intrathecal synthesis of this component of the complement system in different infectious diseases of the central nervous system and is especially useful for patients with blood-brain barrier dysfunction.

  10. Identification of Ambiguous Activities in Radionuclide Cisternography Using SPECT/CT: Aspirated and Ingested CSF Rhinorrhea

    Lee, Dong Yun; Kim, Jae Seung [Univ. of Ulsan College of Medicine, Ulsan (Korea, Republic of)


    A 2 year-old little girl underwent Tc-99m diethylenthriamine pentaacetic acid (DTPA) radionuclide cisternography to evaluate CSF rhinorrhea (Fig. 1). Cisternography clearly showed consecutive tracer activity in the nasal cavity and nasal tip, reflecting cerebrospinal fluid (CSF) leakage. However, several unexpected activities appeared on the bilateral mid- and unilateral lower thorax on delayed images, respectively. We performed additional SPECT/CT to delineate the CSF leakage tract and identify the unexpected activities. Through SPECT/CT, we could confirm that the mid-thoracic activity was in the lung parenchyma, while the lower thoracic activity was in the stomach. Thus, we speculated that these unexpected activities were the result of aspirated and ingested CSF rhinorrhea. CSF rhinorrhea occurs when there is a fistula between the dura mater and the skull base and discharge of CSF from the nose. A spinal fluid leak from the intracranial space to the nasal respiratory tract is potentially very serious because of the risk of an ascending infection that could produce fulminant meningitis. Therefore, identification of the fistulous tract is helpful for patient management. Radionuclide cisternography is an important imaging modality to detect the site of leakage in patients with CSF rhinorrhea. The combination of radionuclide cistenography and SPECT/CT has led to a major improvement in the diagnostic accuracy for localization of CSF leakage. This case also shows an important role for SPECT/CT fusion imaging in radionuclide cisternography not only for localizing the primary CSF fistula tract, but also for evaluating ambiguous radiotracer activities in planar imaging; these ultimately turned out to be aspirated and ingested CSF rhinorrhea.

  11. Cost and clinical analysis of autologous hematopoietic stem cell mobilization with G-CSF and plerixafor compared to G-CSF and cyclophosphamide.

    Shaughnessy, Paul; Islas-Ohlmayer, Miguel; Murphy, Julie; Hougham, Maureen; MacPherson, Jill; Winkler, Kurt; Silva, Matthew; Steinberg, Michael; Matous, Jeffrey; Selvey, Sheryl; Maris, Michael; McSweeney, Peter A


    Plerixafor plus granulocyte-colony stimulating factor (G-CSF) has been shown to mobilize more CD34(+) cells than G-CSF alone for autologous hematopoietic stem cell transplantation (HSCT). However, many centers use chemotherapy followed by G-CSF to mobilize CD34(+) cells prior to HSCT. We performed a retrospective study of patients who participated in the expanded access program (EAP) of plerixafor and G-CSF for initial mobilization of CD34(+) cells, and compared outcomes to matched historic controls mobilized with cyclophosphamide 3-5 g/m(2) and G-CSF at 2 centers that participated in the EAP Control patients were matched for age, sex, disease, disease stage, and number of prior therapies. Mobilization costs were defined to be the costs of medical procedures, resource utilization, and medications. Median national CMS reimbursement rates were used to establish the costs of procedures, hospitalization, provider visits, apheresis, CD34(+) cell processing and cryopreservation. Average sale price was used for G-CSF, plerixafor, cyclophosphamide, MESNA, antiemetics, and antimicrobials. A total of 33 patients from the EAP and 33 matched controls were studied. Two patients in the control group were hospitalized for neutropenic fever during the mobilization period. Apheresis started on the scheduled day in 33 (100%) study patients and in 29 (88%) control patients (P = 0.04). Sixteen (48%) control patients required weekend apheresis. There was no difference in number of CD34(+) cells collected between the groups, and all patients proceeded to HSCT with no difference in engraftment outcomes. Median total cost of mobilization was not different between the plerixafor/G-CSF and control groups ($14,224 versus $18,824; P = .45). In conclusion, plerixafor/G-CSF and cyclophosphamide/G-CSF for upfront mobilization of CD34(-) cells resulted in similar numbers of cells collected, costs of mobilization, and clinical outcomes. Additionally, plerixafor/G-CSF mobilization resulted in more

  12. Ideological commitment and posttraumatic stress in former Tamil child soldiers.

    Kanagaratnam, Pushpa; Raundalen, Magne; Asbjørnsen, Arve E


    This study focuses on the impact of present ideological commitment on posttraumatic stress symptoms in former child soldiers living in exile. Eighteen men and two women (aged 25-37), who had joined different Tamil armed groups in Sri Lanka between the ages of 13 and 17 years, participated. The Impact of Event Scale was used to measure posttraumatic symptoms. Qualitative methods were used to investigate the participants' ideological commitment. Participants reported being exposed to many potentially traumatizing events, and had high scores on the Impact of Event Scale. Twenty-five percent of the sample showed strong ideological commitment to the "cause". Ideological commitment at the present seemed to predict better mental health when exposure was less intense and overwhelming. Time had a negative impact on ideological commitment.

  13. For soldier and state: dual loyalty and World War One.

    van Bergen, Leo


    Military medicine has always been characterized by some form of dual loyalty: physicians have to consider the interests of the individual soldier--patient as well as the interests of the state and the military in general. The way in which each individual doctor responds to this dual loyalty has mostly been viewed as a product of war circumstances on the one hand, and the personal character and/or religious and ideological beliefs of the physician on the other. Taking World War One as an example, this article argues that the nature of the illness or wound also had a part to play in this. The article shows that the disfigured were looked upon mainly in relation to the patient's own interests; the invalided-out through a combination of the patient's as well as the state's interests; and the neurotic mainly out of concern for the interests of the state.

  14. Enteric fever in a British soldier from Sierra Leone.

    Osborne, Lucy G; Brown, M; Bailey, M S


    Enteric fever (typhoid and paratyphoid) remains a threat to British troops overseas and causes significant morbidity and mortality. We report the case of a soldier who developed typhoid despite appropriate vaccination and field hygiene measures, which began 23 days after returning from a deployment in Sierra Leone. The incubation period was longer than average, symptoms started 2 days after stopping doxycycline for malaria chemoprophylaxis and initial blood cultures were negative. The Salmonella enterica serovar Typhi eventually isolated was resistant to amoxicillin, co-amoxiclav, co-trimoxazole and nalidixic acid and had reduced susceptibility to ciprofloxacin. He was successfully treated with ceftriaxone followed by azithromycin, but 1 month later he remained fatigued and unable to work. The clinical and laboratory features of enteric fever are non-specific and the diagnosis should be considered in troops returning from an endemic area with a febrile illness. Multiple blood cultures and referral to a specialist unit may be required.

  15. TNF alpha acts in synergy with GM-CSF to induce proliferation of acute myeloid leukemia cells by up-regulating the GM-CSF receptor and GM-CSF gene expression.

    Brailly, H; Pebusque, M J; Tabilio, A; Mannoni, P


    Acute myeloid leukemia (AML) cells are dependent for their survival and proliferation on hematopoietic growth factors. As tumor necrosis factor alpha (TNF alpha) can increase the proliferation of primary cultures of AML cells, we have investigated the effect of TNF alpha on the autocrine and/or paracrine growth control by one of the major AML growth factor, granulocyte-macrophage colony-stimulating factor (GM-CSF). First, a panel of AML cells were analysed with respect to their proliferative response to TNF alpha. We provide experimental evidence that TNF alpha induces both GM-CSF gene expression and up-regulation of high-affinity GM-CSF membrane receptor in TNF alpha-responsive cells. This effect is not restricted to the malignant phenotype, although it could account for the selective growth advantage of the leukemic clone over the normal cells upon TNF alpha stimulation.

  16. Occupational Lung Diseases among Soldiers Deployed to Iraq and Afghanistan.

    Szema, Anthony M


    Military personnel deployed to Iraq and Afghanistan, from 2004 to the present, has served in a setting of unique environmental conditions. Among these are exposures to burning trash in open air "burn pits" lit on fire with jet fuel JP-8. Depending on trash burned--water bottles, styrofoam trays, medical waste, unexploded munitions, and computers--toxins may be released such as dioxins and n-hexane and benzene. Particulate matter air pollution culminates from these fires and fumes. Additional environmental exposures entail sandstorms (Haboob, Shamal, and Sharqi) which differ in direction and relationship to rain. These wars saw the first use of improvised explosive devices (roadside phosphate bombs),as well as vehicle improvised explosive devices (car bombs), which not only potentially aerosolize metals, but also create shock waves to induce lung injury via blast overpressure. Conventional mortar rounds are also used by Al Qaeda in both Iraq and Afghanistan. Outdoor aeroallergens from date palm trees are prevalent in southern Iraq by the Tigris and Euphrates rivers, while indoor aeroallergen aspergillus predominates during the rainy season. High altitude lung disease may also compound the problem, particularly in Kandahar, Afghanistan. Clinically, soldiers may present with new-onset asthma or fixed airway obstruction. Some have constrictive bronchiolitis and vascular remodeling on open lung biopsy - despite having normal spirometry and chest xrays and CT scans of the chest. Others have been found to have titanium and other metals in the lung (rare in nature). Still others have fulminant biopsy-proven sarcoidiosis. We found DNA probe-positive Mycobacterium Avium Complex in lung from a soldier who had pneumonia, while serving near stagnant water and camels and goats outside Abu Gharib. This review highlights potential exposures, clinical syndromes, and the Denver Working Group recommendations on post-deployment health.

  17. Getting CSR communication fit

    Schmeltz, Line


    Companies experience increasing legal and societal pressure to communicate about their corporate social responsibility (CSR) engagements from a number of different publics. One very important group is that of young consumers who are predicted to be the most important and influential consumer group...... in the near future. From a value- theoretical base, this article empirically explores the role and applicability of ‘fit’ in strategic CSR communication targeted at young consumers. Point of departure is taken in the well-known strategic fit (a logical link between a company’s CSR commitment and its core...... values) and is further developed by introducing two additional fits, the CSR- Consumer fit and the CSR-Consumer-Company fit (Triple Fit). Through a sequential design, the three fits are empirically tested and their potential for meeting young consumers’ expectations for corporate CSR messaging...

  18. Indero: intergenerational trauma and resilience between Burundian former child soldiers and their children.

    Song, Suzan Joon; Tol, Wietse; de Jong, Joop


    Since many former child soldiers are aging and having children of their own, this study aimed to understand how the effects of trauma are passed to the next generation. In this qualitative study, semistructured interviews, focus groups, and observations were conducted with 25 former child soldiers and 15 matched civilian parents. Analysis used a grounded-theory approach. Trauma may be transmitted from former child soldiers to their offspring via (a) the effect on indero (how to raise a child); (b) severe parental emotional distress; and (c) community effects. Incorporating themes of indero values on how to raise children, the effects of parental posttraumatic stress and depressive symptoms on offspring, and the stigma associated with the families of former child soldiers may provide key areas of intervention in mental healing. © 2014 FPI, Inc.

  19. High prevalence of syphilis among demobilized child soldiers in Eastern Congo: a cross-sectional study

    Lutala Prosper


    Full Text Available Abstract Background Syphilis, a known major public health issue for soldiers during periods of conflict, is exacerbated in the Democratic Republic of Congo due to widespread sexual violence. However, there has been no previous study to determine the extent of this problem. Therefore, we determined the prevalence of syphilis among young demobilized soldiers. Methods Screening of syphilis using the rapid plasma reagin test and the Treponema pallidum hemagglutination assay was conducted in three transit sites of soldier reintegration in 2005. The Fisher Exact probability test was used to compare results. Results The prevalence of syphilis was found to be 3.4%, with almost equal distribution in respect to sex, location. Conclusion Syphilis continues to be highly prevalent in demobilized child soldiers in Eastern Congo. Syphilis screening tests are recommended.

  3. Victims and/or perpetrators? Towards an interdisciplinary dialogue on child soldiers.

    Derluyn, Ilse; Vandenhole, Wouter; Parmentier, Stephan; Mels, Cindy


    Worldwide, thousands of children are acting in different roles in armed groups. Whereas human rights activism and humanitarian imperatives tend to emphasize the image of child soldiers as incapable victims of adults' abusive compulsion, this image does not fully correspond with prevailing pedagogical and jurisprudential discourses, nor does it represent all child soldiers' own perceptions of their role. Moreover, contemporary warfare is often marked by fuzzy distinctions between perpetrators and victims. This article deepens on the question how to conceptualize the victim-perpetrator imaginary about child soldiers, starting from three disciplines, children's rights law, psychosocial approaches and transitional justice, and then proceeding into an interdisciplinary approach. We argue that the victim-perpetrator dichotomy in relation to child soldiers needs to be revisited, and that this can only be done successfully through a truly interdisciplinary approach. Key to this interdisciplinary dialogue is the growing awareness within all three disciplines, but admittedly only marginally within children's rights law, that only by moving beyond the binary distinction between victim- and perpetrator-hood, the complexity of childhood soldiering can be grasped. In transitional justice, the concept of role reversal has been instructive, and in psychosocial studies, emphasis has been put on the 'agency' of (former) child soldiers, whereby child soldiers sometimes account on how joining the armed force or group was (partially) out of their own free will. Hence, child soldiers' perpetrator-hood is not only part of the way child soldiers are perceived in the communities they return to, but equally of the way they see themselves. These findings plea for more contextualized approaches, including a greater participation of child soldiers, the elaboration of accountability mechanisms beyond criminal responsibility, and an intimate connection between individual, social and societal

  4. Optimization of auto-induction medium for G-CSF production by Escherichia coli using artificial neural networks coupled with genetic algorithm.

    Tian, H; Liu, C; Gao, X D; Yao, W B


    Granulocyte colony-stimulating factor (G-CSF) is a cytokine widely used in cancer patients receiving high doses of chemotherapeutic drugs to prevent the chemotherapy-induced suppression of white blood cells. The production of recombinant G-CSF should be increased to meet the increasing market demand. This study aims to model and optimize the carbon source of auto-induction medium to enhance G-CSF production using artificial neural networks coupled with genetic algorithm. In this approach, artificial neural networks served as bioprocess modeling tools, and genetic algorithm (GA) was applied to optimize the established artificial neural network models. Two artificial neural network models were constructed: the back-propagation (BP) network and the radial basis function (RBF) network. The root mean square error, coefficient of determination, and standard error of prediction of the BP model were 0.0375, 0.959, and 8.49 %, respectively, whereas those of the RBF model were 0.0257, 0.980, and 5.82 %, respectively. These values indicated that the RBF model possessed higher fitness and prediction accuracy than the BP model. Under the optimized auto-induction medium, the predicted maximum G-CSF yield by the BP-GA approach was 71.66 %, whereas that by the RBF-GA approach was 75.17 %. These predicted values are in agreement with the experimental results, with 72.4 and 76.014 % for the BP-GA and RBF-GA models, respectively. These results suggest that RBF-GA is superior to BP-GA. The developed approach in this study may be helpful in modeling and optimizing other multivariable, non-linear, and time-variant bioprocesses.

  11. Antiretroviral treatment reduces increased CSF neurofilament protein (NFL) in HIV-1 infection.

    Mellgren, A; Price, R W; Hagberg, L; Rosengren, L; Brew, B J; Gisslén, M


    Increased levels of the light-chain neurofilament protein (NFL) in CSF provide a marker of CNS injury in several neurodegenerative disorders and have been reported in the AIDS dementia complex (ADC). We examined the effects of highly active antiretroviral treatment (HAART) on CSF NFL in HIV-1-infected subjects with and without ADC who underwent repeated lumbar punctures (LPs). NFL was measured by ELISA (normal reference value NFL at baseline, with a median level of 780 ng/L and an intraquartile range (IQR) of 480 to 7300. After 3 months of treatment, NFL concentrations had fallen to normal in 48% (10/21), and the median decreased to 340 ng/L (IQR NFL levels. Thirty-two subjects had normal NFL at baseline, and all but one remained normal at follow-up. These effects on CSF NFL were seen in association with clinical improvement in ADC patients, decreases in plasma and CSF HIV-1 RNA and CSF neopterin, and increases in blood CD4 T cell counts. HAART seems to halt the neurodegenerative process(es) caused by HIV-1, as shown by the significant decrease in CSF NFL after treatment initiation. CSF NFL may serve as a useful marker in monitoring CNS injury in HIV-1 infection and in evaluating CNS efficacy of antiretroviral therapy.

  12. Consensus Guidelines for CSF and Blood Biobanking for CNS Biomarker Studies

    Charlotte E. Teunissen


    Full Text Available There is a long history of research into body fluid biomarkers in neurodegenerative and neuroinflammatory diseases. However, only a few biomarkers in cerebrospinal fluid (CSF are being used in clinical practice. Anti-aquaporin-4 antibodies in serum are currently useful for the diagnosis of neuromyelitis optica (NMO, but we could expect novel CSF biomarkers that help define prognosis and response to treatment for this disease. One of the most critical factors in biomarker research is the inadequate powering of studies performed by single centers. Collaboration between investigators is needed to establish large biobanks of well-defined samples. A key issue in collaboration is to establish standardized protocols for biobanking to ensure that the statistical power gained by increasing the numbers of CSF samples is not compromised by pre-analytical factors. Here, consensus guidelines for CSF collection and biobanking are presented, based on the guidelines that have been published by the BioMS-eu network for CSF biomarker research. We focussed on CSF collection procedures, pre-analytical factors and high quality clinical and paraclinical information. Importantly, the biobanking protocols are applicable for CSF biobanks for research targeting any neurological disease.

  13. Colony stimulating factor (CSF) from human leukemic urine: affinity chromatography and isoelectric focusing.

    Kellar, K L; Vogler, W R; Kinkade, J M


    Biological activities associated with colony-stimulating factor (CSF) from human leukemic urine were found to be selectively retained on an affinity adsorbent of Con A-Sepharose. Elution of activity was achieved using a linear gradient of eith alpha-methyl-D-mannopyranoside (alphaMM) or alpha-methyl-D-glucopyranoside (alphaMG), and resulted in significant increases in specific biological activity. Rechromatography of appropriate fractions indicated that retention of CSF activities was not artifactual. Pretreatment of the affinity matrix with alphaMM completely inhibited binding of CSF. Affinity chromatography of CSF on a Blue Dextran-Sepharose adsorbent was found to be an effective method for removing albumin, a major protein contaminant in urinary preparations. Treatment of CSF with neuraminidase had no effect on its in vitro activity; however, such treatment resulted in an increase in the isoelectric point of CSF from pH 3.5 to pH 4.7, as determined using both sucrose and polyacrylamide gel stabilized pH gradients. Relatively broad regions of biological activity were observed following isoelectric focusing of both neuraminidase-treated and untreated CSF, suggesting that activity was associated with a heterogeneous/polydisperse population of molecular species.

  14. MafB antagonizes phenotypic alteration induced by GM-CSF in microglia.

    Koshida, Ryusuke; Oishi, Hisashi; Hamada, Michito; Takahashi, Satoru

    Microglia are tissue-resident macrophages which are distributed throughout the central nervous system (CNS). Recent studies suggest that microglia are a unique myeloid population distinct from peripheral macrophages in terms of origin and gene expression signature. Granulocyte-macrophage colony-stimulating factor (GM-CSF), a pleiotropic cytokine regulating myeloid development, has been shown to stimulate proliferation and alter phenotype of microglia in vitro. However, how its signaling is modulated in microglia is poorly characterized. MafB, a bZip transcriptional factor, is highly expressed in monocyte-macrophage lineage cells including microglia, although its role in microglia is largely unknown. We investigated the crosstalk between GM-CSF signaling and MafB by analyzing primary microglia. We found that Mafb-deficient microglia grew more rapidly than wild-type microglia in response to GM-CSF. Moreover, the expression of genes associated with microglial differentiation was more downregulated in Mafb-deficient microglia cultured with GM-CSF. Notably, such differences between the genotypes were not observed in the presence of M-CSF. In addition, we found that Mafb-deficient microglia cultured with GM-CSF barely extended their membrane protrusions, probably due to abnormal activation of RhoA, a key regulator of cytoskeletal remodeling. Altogether, our study reveals that MafB is a negative regulator of GM-CSF signaling in microglia. These findings could provide new insight into the modulation of cytokine signaling by transcription factors in microglia.

  15. Increased CSF-BACE1 activity associated with decreased hippocampus volume in Alzheimer's disease.

    Ewers, Michael


    The enzyme beta-secretase (BACE1) is essentially involved in the production of cerebral amyloidogenic pathology in Alzheimer\\'s disease (AD). The measurement of BACE1 activity in cerebrospinal fluid (CSF) has been reported, which may render CSF measurement of BACE1 a potential biomarker candidate of AD. In order to investigate whether BACE1 protein activity is correlated with regional brain atrophy in AD, we investigated the association between CSF levels of BACE1 and MRI-assessed hippocampus volume in patients with AD (n = 30). An increase in CSF-BACE1 activity was associated with decreased left and right hippocampus volume corrected for global head volume in the AD patients. Boot-strapped regression analysis showed that increased CSF levels of BACE1 activity were associated with increased CSF concentration of total tau but not amyloid-beta1-42 in AD. White matter hyperintensities did not influence the results. BACE1 activity and protein levels were significantly increased in AD compared to 19 elderly healthy controls. Thus, the CSF biomarker candidate of BACE1 activity was associated with hippocampus atrophy in AD in a robust manner and may reflect neurotoxic amyloid-beta-related processes.

  16. Diagnostic Utility of CSF Tau and A in Dementia: A Meta-Analysis

    Rachna Agarwal


    Full Text Available CSF tau and Aβ42 are considered as important markers to diagnose Alzheimer’s disease in early stages. Hence, it is important to assess their status in different types of dementia. The main objective of this study was to assess whether these CSF biomarkers can be used to make the differential diagnosis of AD. In the present study, articles published from 1998 till 2009 were taken and meta-analysis was performed to clarify the consistency in trends of biomarkers- CSF tau and Aβ42 in AD and other dementias and whether the same can be used as diagnostic biomarkers for its early diagnosis. 11 out of 60 for CSF tau and 07 out of 40 for CSF Aβ42, dementia case-control studies were selected for final analysis. Descriptive statistics shows that median effect size (raw mean difference of CSF tau was 429 pg/mL (range: 32 to 910 pg/mL in AD whereas in Dementia due to other causes (DOC studies it was 69 pg/mL (range: −53 to 518 pg/mL. Similarly the median effect size of CSF Aβ42 levels was −442 pg/mL (range: −652 to −41.200 pg/mL whereas in DOC studies it was −193 pg/mL (range: −356 to −33 pg/mL.

  17. Flow cytometry of cerebrospinal fluid (CSF) lymphocytes: alterations of blood/CSF ratios of lymphocyte subsets in inflammation disorders of human central nervous system (CNS).

    Kleine, T O; Albrecht, J; Zöfel, P


    Flow cytometry was adapted to measure lymphocytes in human cerebrospinal fluid (CSF). The method was sufficiently precise, reproducible and accurate despite low cell counts. In lumbar CSF of controls with 500 to 3500 (10(3)/l) leukocytes, lymphocyte counts correlated with those in corresponding venous blood: blood/CSF ratios of approximately 2000 : 1 were found for total T cells (CD3+) and CD3+ HLA-DR-, CD3+4+, CD3+8+ subsets, ratios were increased for the lymphocyte subsets CD3+ HLA-DR+ blood-brain and blood-CSF barriers) to blood lymphocyte subsets which favor the transfer of T subsets. Correlation of the subset ratios to the CD3+ ratio indicates distinct barrier properties which changed differently with acute and subacute inflammations and neuroimmunological diseases of central nervous system (CNS) in lumbar or ventricular CSF, but not with simple protein barrier disturbance. HLA DR+ T ratios were higher than HLA DR- T ratios only with controls and some neuroimmunological diseases. Lymphocyte barrier characteristics were related to protein leakage situated at the same barriers, indicating for the lymphocyte subsets selective transfer routes in control subjects and non-selective routes in patients with CNS inflammation where altered ratios revealed a mixture of both routes.

  18. The cytokine network of wallerian degeneration: IL-10 and GM-CSF.

    Be'eri, H; Reichert, F; Saada, A; Rotshenker, S


    Wallerian degeneration (WD) is the inflammatory response of peripheral nerves to injury. Evidence is provided that granulocyte macrophage colony stimulating factor (GM-CSF) contributes to the initiation and progression of WD by activating macrophages and Schwann, whereas IL-10 down-regulates WD by inhibiting GM-CSF production. A significant role of activated macrophages and Schwann for future regeneration is myelin removal by phagocytosis and degradation. We studied the timing and magnitude of GM-CSF and IL-10 production, macrophage and Schwann activation, and myelin degradation in C57BL/6NHSD and C57BL/6-WLD/OLA/NHSD mice that display normal rapid-WD and abnormal slow-WD, respectively. We observed the following events in rapid-WD. The onset of GM-CSF production is within 5 h after injury. Production is steadily augmented during the first 3 days, but is attenuated thereafter. The onset of production of the macrophage and Schwann activation marker Galectin-3/MAC-2 succeeds that of GM-CSF. Galectin-3/MAC-2 production is up-regulated during the first 6 days, but is down-regulated thereafter. The onset of myelin degradation succeeds that of Galectin-3/MAC-2, and is almost complete within 1 week. IL-10 production displays two phases. An immediate low followed by a high that begins on the fourth day, reaching highest levels on the seventh. The timing and magnitude of GM-CSF production thus enable the rapid activation of macrophages and Schwann that consequently phagocytose and degrade myelin. The timing and magnitude of IL-10 production suggest a role in down-regulating WD after myelin is removed. In contrast, slow-WD nerves produce low inefficient levels of GM-CSF and IL-10 throughout. Therefore, deficient IL-10 levels cannot account for inefficient GM-CSF production, whereas deficient GM-CSF levels may account, in part, for slow-WD.

  19. A scalable soldier-machine interface for human-robotic interaction

    Samples, Brian A.


    As part of the Crew-Automated and integration Testbed (CAT) Advanced Technology Objective (ATO), the US Army Tank-automotive and Armaments Research, Development, and Engineering Center (TARDEC) developed crew stations that provided soldiers the ability to control both manned and unmanned vehicles. The crew stations were designed to optimize soldier workload and provide the ability to conduct mission planning, route planning, reconnaissance, surveillance, and target acquisition (RSTA), and fire control capabilities. The crew station software is fully configurable, portable (between crew stations), and interoperable with one another. However, the software architecture was optimized for the specific computing platform utilized by each crew station and user interfaces were hard coded. Current CAT crew station capabilities are required to execute on other crew station configurations as well as handheld devices to meet the needs of expanded soldier roles, including dismounted infantry. TARDEC is currently exploring ways to develop a scalable software architecture that is able to adapt to the physical characteristics of differing computing platforms and devices. In addition, based upon a soldier's role, the software must be able to adapt and optimize the displays based upon individual soldier needs. And finally, the software must be capable of applying a unique style to the presentation of information to the soldier. Future programs require more robust software architectures that take these requirements into account. This paper will describe how scalable software architectures can be designed to address each of these unique requirements.

  20. Higher aggression towards closer relatives by soldier larvae in a polyembryonic wasp.

    Dunn, Johanna; Dunn, Derek W; Strand, Michael R; Hardy, Ian C W


    In the polyembryonic wasp Copidosoma floridanum, females commonly lay one male and one female egg in a lepidopteran host. Both sexes proliferate clonally within the growing host larva. Distinct larval castes develop from each wasp egg, the majority being 'reproductives' plus some 'soldiers' which sacrifice reproduction and attack competitors. Maturing mixed sex broods are usually female biased, as expected when intra-brood mating is common. Pre-mating dispersal followed by outbreeding is expected to increase sexual conflict over brood sex ratios and result in greater soldier attack rates. Owing to sexually asymmetric relatedness, intra-brood conflicts are expected to be resolved primarily via female soldier attack. We observed soldier behaviour in vitro to test whether lower intra-brood relatedness (siblings from either within-strain or between-strain crosses were presented) increased inter-sexual aggression by female as well as male soldiers. As found in prior studies, females were more aggressive than males but, contrary to expectations and previous empirical observations, soldiers of both sexes showed more aggression towards more closely related embryos. We speculate that lower intra-brood relatedness indicates maternal outbreeding and may suggest a rarity of mating opportunities for reproductives maturing from the current brood, which may enhance the value of opposite sex brood-mates, or that higher aggression towards relatives may be a side-effect of mechanisms to discriminate heterospecific competitors.

  1. Trends in mental health services utilization and stigma in US soldiers from 2002 to 2011.

    Quartana, Phillip J; Wilk, Joshua E; Thomas, Jeffrey L; Bray, Robert M; Rae Olmsted, Kristine L; Brown, Janice M; Williams, Jason; Kim, Paul Y; Clarke-Walper, Kristina; Hoge, Charles W


    We characterized trends in mental health services utilization and stigma over the course of the Afghanistan and Iraq wars among active-component US soldiers. We evaluated trends in mental health services utilization and stigma using US Army data from the Health-Related Behavior (HRB) surveys from 2002, 2005, and 2008 (n = 12,835) and the Land Combat Study (LCS) surveys administered to soldiers annually from 2003 to 2009 and again in 2011 (n = 22,627). HRB and LCS data suggested increased mental health services utilization and decreased stigma in US soldiers between 2002 and 2011. These trends were evident in soldiers with and without posttraumatic stress disorder (PTSD), major depressive disorder (MDD), or PTSD and MDD. Despite the improving trends, more than half of soldiers with mental health problems did not report seeking care. Mental health services utilization increased and stigma decreased over the course of the wars in Iraq and Afghanistan. Although promising, these findings indicate that a significant proportion of US soldiers meeting criteria for PTSD or MDD do not utilize mental health services, and stigma remains a pervasive problem requiring further attention.

    mobilizing monocytes and PMNs from the bone marrow, GM-CSF, G-CSF and IL-3 select subsets of dendritic cells, which subsequently induce distinct Th responses. Therefore, the present study examines the correlation between the mobilizing cytokines in serum and the Th responses. The IFN-gamma and IL-4...... lung function. In addition, an inverse correlation between IL-3 and IFN-gamma was observed. The results indicate involvement of endogenous GM-CSF, G-CSF and IL-3 in the skewed Th response in CF, and change to a Th1-dominated response might be achieved with GM-CSF treatment....

  4. CSF neurofilament light chain is elevated in OMS (decreasing with immunotherapy) and other pediatric neuroinflammatory disorders.

    Pranzatelli, Michael R; Tate, Elizabeth D; McGee, Nathan R; Verhulst, Steven J


    Using a panel of seven brain cell-specific biomarkers in cerebrospinal fluid (CSF), pediatric opsoclonus-myoclonus syndrome (OMS) (n=234) was compared to pediatric non-inflammatory neurological controls (n=84) and other inflammatory neurological disorders (OIND) (n=44). Only CSF NFL was elevated in untreated OMS versus controls (+83%). It was 87% higher in OIND than in OMS. On combination treatment with front-loaded ACTH, IVIg, rituximab, median CSF NFL decreased by 60% to control levels. These biochemical data suggest neuronal/axonal injury in some children with OMS without indicators of astrogliosis, and reduction on sufficient immunotherapy.

  10. Multiple Past Concussions Are Associated with Ongoing Post-Concussive Symptoms but Not Cognitive Impairment in Active-Duty Army Soldiers.

    Dretsch, Michael N; Silverberg, Noah D; Iverson, Grant L


    The extent to which multiple past concussions are associated with lingering symptoms or mental health problems in military service members is not well understood. The purpose of this study was to examine the association between lifetime concussion history, cognitive functioning, general health, and psychological health in a large sample of fit-for-duty U.S. Army soldiers preparing for deployment. Data on 458 active-duty soldiers were collected and analyzed. A computerized cognitive screening battery (CNS-Vital Signs(®)) was used to assess complex attention (CA), reaction time (RT), processing speed (PS), cognitive flexibility (CF), and memory. Health questionnaires included the Neurobehavioral Symptom Inventory (NSI), PTSD Checklist-Military Version (PCL-M), Zung Depression and Anxiety Scales (ZDS; ZAS), Perceived Stress Scale (PSS), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and the Alcohol Use and Dependency Identification Test (AUDIT). Soldiers with a history of multiple concussions (i.e., three or more concussions) had significantly greater post-concussive symptom scores compared with those with zero (d=1.83, large effect), one (d=0.64, medium effect), and two (d=0.64, medium effect) prior concussions. Although the group with three or more concussions also reported more traumatic stress symptoms, the results revealed that traumatic stress was a mediator between concussions and post-concussive symptom severity. There were no significant differences on neurocognitive testing between the number of concussions. These results add to the accumulating evidence suggesting that most individuals recover from one or two prior concussions, but there is a greater risk for ongoing symptoms if one exceeds this number of injuries.

  14. Relationship Between Job Burnout and Neuroendocrine Indicators in Soldiers in the Xinjiang Arid Desert: A Cross-Sectional Study

    Ning Tao


    Full Text Available The purpose of this study was to explore the relationship between job burnout and neuroendocrine indicators in soldiers living in a harsh environment. Three hundred soldiers stationed in the arid desert and 600 in an urban area were recruited. They filled in the Chinese Maslach Burnout Inventory questionnaire. One hundred soldiers were randomly selected from each group to measure their levels of noradrenaline, serotonin, heat shock protein (HSP-70, adrenocorticotropic hormone, and serum cortisol. Job burnout was more common in soldiers from urban areas than those from rural areas. Job burnout was significantly higher among soldiers stationed in the arid desert than those in urban areas. For soldiers in the arid desert, the levels of HSP-70, serum cortisol, and adrenocorticotropic hormone were significantly higher than in soldiers in urban areas. Correlation analyses showed that the degree of job burnout was weakly negatively correlated with the level of HSP-70. Being an only child, HSP-70 levels, cortisol levels, and ACTH levels were independently associated with job burnout in soldiers stationed in the arid desert. A higher level of job burnout in soldiers stationed in arid desert and a corresponding change in neuroendocrine indicators indicated a correlation between occupational stress and neurotransmitters.

  16. Limitations of inclusive fitness.

    Allen, Benjamin; Nowak, Martin A; Wilson, Edward O


    Until recently, inclusive fitness has been widely accepted as a general method to explain the evolution of social behavior. Affirming and expanding earlier criticism, we demonstrate that inclusive fitness is instead a limited concept, which exists only for a small subset of evolutionary processes. Inclusive fitness assumes that personal fitness is the sum of additive components caused by individual actions. This assumption does not hold for the majority of evolutionary processes or scenarios. To sidestep this limitation, inclusive fitness theorists have proposed a method using linear regression. On the basis of this method, it is claimed that inclusive fitness theory (i) predicts the direction of allele frequency changes, (ii) reveals the reasons for these changes, (iii) is as general as natural selection, and (iv) provides a universal design principle for evolution. In this paper we evaluate these claims, and show that all of them are unfounded. If the objective is to analyze whether mutations that modify social behavior are favored or opposed by natural selection, then no aspect of inclusive fitness theory is needed.

  17. Extending the Serum Half-Life of G-CSF via Fusion with the Domain III of Human Serum Albumin

    Shuqiang Zhao


    Full Text Available Protein fusion technology is one of the most commonly used methods to extend the half-life of therapeutic proteins. In this study, in order to prolong the half-life of Granulocyte colony stimulating factor (G-CSF, the domain III of human serum albumin (3DHSA was genetically fused to the N-terminal of G-CSF. The 3DHSA-G-CSF fusion gene was cloned into pPICZαA along with the open reading frame of the α-factor signal under the control of the AOX1 promoter. The recombinant expression vector was transformed into Pichia pastoris GS115, and the recombinant strains were screened by SDS-PAGE. As expected, the 3DHSA-G-CSF showed high binding affinity with HSA antibody and G-CSF antibody, and the natural N-terminal of 3DHSA was detected by N-terminal sequencing. The bioactivity and pharmacokinetic studies of 3DHSA-G-CSF were respectively determined using neutropenia model mice and human G-CSF ELISA kit. The results demonstrated that 3DHSA-G-CSF has the ability to increase the peripheral white blood cell (WBC counts of neutropenia model mice, and the half-life of 3DHSA-G-CSF is longer than that of native G-CSF. In conclusion, 3DHSA can be used to extend the half-life of G-CSF.

  18. Autophagy is required for stem cell mobilization by G-CSF

    Leveque-El Mouttie, Lucie; Vu, Therese; Lineburg, Katie E.


    Granulocyte colony-stimulating factor (G-CSF) is widely used clinically to prevent neutropenia after cytotoxic chemotherapy and to mobilize hematopoietic stem cells (HSCs) for transplantation. Autophagy, a process of cytoplasmic component recycling, maintains cellular homeostasis and protects...... the cell during periods of metabolic stress or nutrient deprivation. We have observed that G-CSF activates autophagy in neutrophils and HSCs from both mouse and human donors. Furthermore, G-CSF-induced neutrophil and HSC mobilization is impaired in the absence of autophagy. In contrast, autophagy...... is dispensable for direct HSC mobilization in response to the CXCR4 antagonist AMD3100. Altogether, these data demonstrate an important role for G-CSF in invoking autophagy within hematopoietic and myeloid cells and suggest that this pathway is critical for ensuring cell survival in response to clinically...

  19. CSF markers for diagnosis of bacterial meningitis in neurosurgical postoperative patients

    Tavares Wagner Malagó


    Full Text Available OBJECTIVE: To evaluate the diagnostic usefulness of cerebral spinal fluid (CSF cellularity, protein, neutrophils, glucose and lactate for detection of postoperative bacterial meningitis. METHOD: This prospective study was conducted in 28 postoperative neurosurgical patients from 2002 to 2005 at University of São Paulo. The CSF markers were plotted in a receiver operating characteristic (ROC curve to evaluate their accuracy. RESULTS: Based on the area under ROC curve CSF glucose, cellularity, and lactate were considered good tests. Polymorphonuclear and protein did not achieve enough accuracy to be used clinically. CONCLUSION: The CSF glucose, lactate, and cellularity can be used for the diagnosis of bacterial meningitis. Moreover, it can be helpful to differentiate bacterial from aseptic meningitis.

  20. Isotope cisternography and conductance to outflow of CSF in normal pressure hydrocephalus.

    Børgesen, S E; Westergård, L; Gjerris, F


    In 50 patients with normal pressure hydrocephalus (NPH) the findings on lumbar isotope cisternography (IGG) were compared to the conductance to outflow of CSF (Cout) as measured by lumbo-ventricular perfusion. The purpose was to identify those ICG-characteristics that imply a low Cout and thus may indicate CSF shunting therapy. Normal ICG was found only in three patients, where Cout was not, or only moderately, decreased. There was a significant correlation between a low Cout and occurrence of ventricular retention and absent parasagittal accumulation at 24 hours or later, following injection. These findings may, however, also be present in patients with no, or only moderate, decreased Cout, where CSF shunting may seen unjustified. It is concluded, that the indication for CSF shunting cannot be based on the results of ICG alone.

  2. Fibronectin changes in eosinophilic meningitis with blood-CSF barrier disruption.

    Shyu, Ling-Yuh; Hu, Ming-E; Chou, Chun-Hui; Chen, Ke-Min; Chiu, Ping-Sung; Lai, Shih-Chan


    Fibronectin, which is present at relatively low levels in healthy central nervous systems (CNS), shows increased levels in meningitis. In this study, fibronectin processing was correlated with the increased permeability of the blood-cerebrospinal fluid (CSF) barrier as well as with the formation of eosinophil infiltrates in angiostrongyliasis meningitis. The immunohistochemistry results show matrix metalloproteinase-9 (MMP-9) is localized in the choroid plexus epithelium. Coimmunoprecipitation demonstrated fibronectin strongly binds MMP-9. Furthermore, treatment with the MMP-9 inhibitor GM6001 significantly inhibited fibronectin processing, reduced the blood-CSF barrier permeability, and decreased the eosinophil counts. The decreased fibronectin processing in CSF implies decreased cellular invasion of the subarachnoid space across the blood-CSF barrier. Therefore, increased fibronectin processing may be associated with barrier disruption and participate in the extravasation and migration of eosinophils into the CNS during experimental parasitic infection.

  3. Mild cognitive impairment and Alzheimer patients display different levels of redox-active CSF iron.

    Lavados, Manuel; Guillón, Marta; Mujica, María Cristina; Rojo, Leonel E; Fuentes, Patricio; Maccioni, Ricardo B


    Oxidative stress constitutes a hallmark of Alzheimer's disease (AD). Recent studies also point to redox active metals such as iron, copper and zinc in mediating oxidative stress in AD pathogenesis. However, the reactivity of cerebrospinal fluid (CSF) iron and its possible correlation with the severity of cognitive decline in both Alzheimer's patients and subjects with mild cognitive impairment (MCI) is still unknown. Here we show that different stages of cognitive and functional impairment are associated with changes in CSF reactive iron. In this work, we compared CSF samples from 56 elders, classified into 4 groups according to their scores on the Clinical Dementia Rating scale (CDR). Total CSF iron was analyzed by atomic absorption spectrometry. Redox-active iron was analyzed by a novel fluorimetric assay. One-way ANOVA was used to test differences in mean values, and Newman-Keuls Multiple Comparison Test was used for multi group comparisons. No difference in total CSF iron was found between different groups. Significant amounts of redox-active iron were found in CSF and their levels correlated with the extent of cognitive impairment. Redox-active CSF iron levels increased with the degree of cognitive impairment from normal to MCI subjects, while AD patients showed an abrupt decrease to levels close to zero. Given the relevance of oxidative damage in neurodegeneration, it might be possible to associate the development of cognitive and functional decline with the presence of redox-active iron in the CSF. The decrease in redox-active iron found in AD patients may represent a terminal situation, whereby the central nervous system attempts to minimize iron-associated toxicity.

  4. CXCL13 is the major determinant for B cell recruitment to the CSF during neuroinflammation

    Kowarik Markus C


    Full Text Available Abstract Background The chemokines and cytokines CXCL13, CXCL12, CCL19, CCL21, BAFF and APRIL are believed to play a role in the recruitment of B cells to the central nervous system (CNS compartment during neuroinflammation. To determine which chemokines/cytokines show the strongest association with a humoral immune response in the cerebrospinal fluid (CSF, we measured their concentrations in the CSF and correlated them with immune cell subsets and antibody levels. Methods Cytokine/chemokine concentrations were measured in CSF and serum by ELISA in patients with non-inflammatory neurological diseases (NIND, n = 20, clinically isolated syndrome (CIS, n = 30, multiple sclerosis (MS, n = 20, Lyme neuroborreliosis (LNB, n = 8 and patients with other inflammatory neurological diseases (OIND, n = 30. Albumin, IgG, IgA and IgM were measured by nephelometry. CSF immune cell subsets were determined by seven-color flow cytometry. Results CXCL13 was significantly elevated in the CSF of all patient groups with inflammatory diseases. BAFF levels were significantly increased in patients with LNB and OIND. CXCL12 was significantly elevated in patients with LNB. B cells and plasmablasts were significantly elevated in the CSF of all patients with inflammatory diseases. CXCL13 showed the most consistent correlation with CSF B cells, plasmablasts and intrathecal Ig synthesis. Conclusions CXCL13 seems to be the major determinant for B cell recruitment to the CNS compartment in different neuroinflammatory diseases. Thus, elevated CSF CXCL13 levels rather reflect a strong humoral immune response in the CNS compartment than being specific for a particular disease entity.

  6. CSF-contacting neurons regulate locomotion by relaying mechanical stimuli to spinal circuits

    Böhm, Urs Lucas; Prendergast, Andrew; Djenoune, Lydia; Nunes Figueiredo, Sophie; Gomez, Johanna; Stokes, Caleb; Kaiser, Sonya; Suster, Maximilliano; Kawakami, Koichi; Charpentier, Marine; Concordet, Jean-Paul; Rio, Jean-Paul; Del Bene, Filippo; Wyart, Claire


    International audience; Throughout vertebrates, cerebrospinal fluid-contacting neurons (CSF-cNs) are ciliated cells surrounding the central canal in the ventral spinal cord. Their contribution to modulate locomotion remains undetermined. Recently, we have shown CSF-cNs modulate locomotion by directly projecting onto the locomotor central pattern generators (CPGs), but the sensory modality these cells convey to spinal circuits and their relevance to innate locomotion remain elusive. Here, we d...

  7. GM-CSF Differentially Regulates Eosinophil and Neutrophil Adhesive Interactions with Vascular Endothelium in Vivo

    Nooshin Sheikh Bahaie


    Full Text Available Allergic airway inflammation is characterized by elaboration of cytokines and chemokines leading to recruitment of inflammatory leukocytes, predominantly eosinophils, to the airways. Granulocyte macrophage colony stimulating factor (GM-CSF is generated in the lungs of human subjects with asthma in response to allergen challenge and is necessary for the development of allergen-induced bronchial eosinophilia in mice. The effect of GM-CSF on human eosinophil and neutrophil interactions with the vascular endothelium under conditions of blood flow was investigated in post-capillary venules of the rabbit mesentery by intravital microscopy.While GM-CSF significantly reduced the rolling fraction of neutrophils in vivo and induced consistent shedding of neutrophil L-selectin in vitro, its effect on eosinophil rolling was variable. Eosinophils from 57% of the donors demonstrated inhibition of rolling, while eosinophils from the remaining 43% of donors demonstrated no inhibition or increased rolling. The variable effect of GM-CSF on inhibition of eosinophil rolling was associated with variable shedding of L-selectin in vitro. In contrast to the differential effect of GM-CSF on neutrophils versus eosinophils, stimulation with phorbol myristate acetate demonstrated a similar degree of inhibition of rolling and L-selectin shedding by neutrophils and eosinophils suggesting that there was no defect in L-selectin shedding in the eosinophil donors who did not respond to GM-CSF. Overall, these studies demonstrate that GM-CSF consistently inhibits interaction of neutrophils with endothelium in vivo, whereas its effect on eosinophil-endothelial interactions is variable. GM-CSF may thus be one factor accounting for the varying percentage of eosinophils and neutrophils recruited to sites of allergic inflammation in different individuals.

  8. CSF1R mutations link POLD and HDLS as a single disease entity.

    Nicholson, Alexandra M; Baker, Matt C; Finch, Nicole A; Rutherford, Nicola J; Wider, Christian; Graff-Radford, Neill R; Nelson, Peter T; Clark, H Brent; Wszolek, Zbigniew K; Dickson, Dennis W; Knopman, David S; Rademakers, Rosa


    Pigmented orthochromatic leukodystrophy (POLD) and hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) are rare neurodegenerative disorders characterized by cerebral white matter abnormalities, myelin loss, and axonal swellings. The striking overlap of clinical and pathologic features of these disorders suggested a common pathogenesis; however, no genetic or mechanistic link between POLD and HDLS has been established. Recently, we reported that mutations in the colony-stimulating factor 1 receptor (CSF1R) gene cause HDLS. In this study, we determined whether CSF1R mutations are also a cause of POLD. We performed sequencing of CSF1R in 2 pathologically confirmed POLD families. For the largest family (FTD368), a detailed case report was provided and brain samples from 2 affected family members previously diagnosed with POLD were re-evaluated to determine whether they had HDLS features. In vitro functional characterization of wild-type and mutant CSF1R was also performed. We identified CSF1R mutations in both POLD families: in family 5901, we found c.2297T>C (p.M766T), previously reported by us in HDLS family CA1, and in family FTD368, we identified c.2345G>A (p.R782H), recently reported in a biopsy-proven HDLS case. Immunohistochemical examination in family FTD368 showed the typical neuronal and glial findings of HDLS. Functional analyses of CSF1R mutant p.R782H (identified in this study) and p.M875T (previously observed in HDLS), showed a similar loss of CSF1R autophosphorylation of selected tyrosine residues in the kinase domain for both mutations when compared with wild-type CSF1R. We provide the first genetic and mechanistic evidence that POLD and HDLS are a single clinicopathologic entity.

  9. Chimeric HIV-1 envelope glycoproteins with potent intrinsic granulocyte-macrophage colony-stimulating factor (GM-CSF activity.

    Gözde Isik

    Full Text Available HIV-1 acquisition can be prevented by broadly neutralizing antibodies (BrNAbs that target the envelope glycoprotein complex (Env. An ideal vaccine should therefore be able to induce BrNAbs that can provide immunity over a prolonged period of time, but the low intrinsic immunogenicity of HIV-1 Env makes the elicitation of such BrNAbs challenging. Co-stimulatory molecules can increase the immunogenicity of Env and we have engineered a soluble chimeric Env trimer with an embedded granulocyte-macrophage colony-stimulating factor (GM-CSF domain. This chimeric molecule induced enhanced B and helper T cell responses in mice compared to Env without GM-CSF. We studied whether we could optimize the activity of the embedded GM-CSF as well as the antigenic structure of the Env component of the chimeric molecule. We assessed the effect of truncating GM-CSF, removing glycosylation-sites in GM-CSF, and adjusting the linker length between GM-CSF and Env. One of our designed Env(GM-CSF chimeras improved GM-CSF-dependent cell proliferation by 6-fold, reaching the same activity as soluble recombinant GM-CSF. In addition, we incorporated GM-CSF into a cleavable Env trimer and found that insertion of GM-CSF did not compromise Env cleavage, while Env cleavage did not compromise GM-CSF activity. Importantly, these optimized Env(GM-CSF proteins were able to differentiate human monocytes into cells with a macrophage-like phenotype. Chimeric Env(GM-CSF should be useful for improving humoral immunity against HIV-1 and these studies should inform the design of other chimeric proteins.

  10. Influence of APOE Genotype on Alzheimer’s Disease CSF Biomarkers in a Spanish Population

    J. A. Monge-Argilés


    Full Text Available Objectives. To evaluate the association between apolipoprotein E (APOE genotype and cerebrospinal fluid (CSF levels of Alzheimer’s disease (AD biomarkers and to study the influence of APOE genotype on the development of AD in a Spanish population. Material and Methods. The study comprised 29 amnestic mild cognitive impairment (MCI patients and 27 control subjects. Using ELISA methodology, CSF biomarkers and tau/Aβ ratios were obtained. ANOVA and adjusted odds ratios were calculated. Results. We observed the effect of APOE genotype and age on CSF AD variables. The progression to AD was more clearly influenced by CSF AD variables than by age or APOE status. Conclusions. APOE status influences CSF AD variables. However, the presence of APOE ε4 does not appear to be a deterministic factor for the development of AD, because CSF variables have a greater influence on progression to the disease. These results confirm previous observations and, to our knowledge, are the first published in a Spanish population.

  11. CSF and blood oxytocin concentration changes following intranasal delivery in macaque.

    Olga Dal Monte

    Full Text Available Oxytocin (OT in the central nervous system (CNS influences social cognition and behavior, making it a candidate for treating clinical disorders such as schizophrenia and autism. Intranasal administration has been proposed as a possible route of delivery to the CNS for molecules like OT. While intranasal administration of OT influences social cognition and behavior, it is not well established whether this is an effective means for delivering OT to CNS targets. We administered OT or its vehicle (saline to 15 primates (Macaca mulatta, using either intranasal spray or a nebulizer, and measured OT concentration changes in the cerebral spinal fluid (CSF and in blood. All subjects received both delivery methods and both drug conditions. Baseline samples of blood and CSF were taken immediately before drug administration. Blood was collected every 10 minutes after administration for 40 minutes and CSF was collected once post-delivery, at the 40 minutes time point. We found that intranasal administration of exogenous OT increased concentrations in both CSF and plasma compared to saline. Both delivery methods resulted in similar elevations of OT concentration in CSF, while the changes in plasma OT concentration were greater after nasal spray compared to nebulizer. In conclusion our study provides evidence that both nebulizer and nasal spray OT administration can elevate CSF OT levels.

    Ning Zhu; Jian Cui; Chunxia Qiao; Yan Li; Yuanfang Ma; Jiyan Zhang; Beifen Shen


    M-CSF is a key cytokine in macrophage development by inducing MAPKs activation, and cAMP can inhibit MAPKs activation induced by inflammatory stimuli. To explore the effects of cAMP on M-CSF-induced MAPKs activation and on macrophage development, the model of bone marrow-derived murine macrophages (BMMs) was used. The effects of cAMP on M-CSF-induced MAPKs activation were analyzed by Western blotting assay, and the effects of cAMP on CD14 and F4/80 expression during macrophage development were examined by FACS analysis.Macrophage morphology showed the successful establishment of the model of macrophage development. Western blotting assay revealed that M-CSF activated ERK, JNK and p38 in both mature and immature macrophages, and cAMP inhibited M-CSF-induced ERK, JNK and p38 activation in a time-dependent manner. FACS analysis revealed that macrophage development was impaired with cAMP pretreatment. In conclusion, cAMP modulates macrophage development by suppressing M-CSF-induced MAPKs activation.

    We evaluated the clinical activity of GM-CSF in combination with standard dose rituximab in patients with chronic lymphocytic leukemia (CLL). The rationale for exploring this combination is provided by the ability of GM-CSF to increase surface expression of CD20 in CLL cells and potentially render them a better target for rituximab. GM-CSF also enhances antibody-dependent cellular cytotoxicity against CLL cells. The combination of GM-CSF and rituximab was evaluated as initial treatment in elderly patients with indication for treatment and in patients at high risk for progression identified by elevated beta(2) microglobulin. This combination was also evaluated in patients with recurrent CLL. On the basis of the results of 118 patients, we observed an overall response rate of 65 and 9% complete remission and these results compare favourably with the results obtained with rituximab single agent. This combination was well tolerated with the most common toxicity consisting in mild GM-CSF injection site erythema. On the basis of this experience, we are currently evaluating the use of GM-CSF in combination with the chemoimmunotherapy regimen fludarabine, cyclophosphamide and rituximab.

    Bilingualism as a component of cognitive reserve has been claimed to delay the onset of Alzheimer's disease (AD). However, its effect on cerebrospinal fluid (CSF) AD-biomarkers has not been investigated. We assessed cognitive performance and CSF AD-biomarkers, and potential moderation effect of bilingualism on the association between age, CSF AD-biomarkers, and cognition. Cognitively healthy middle-aged participants classified as monolinguals (n = 100, nCSF = 59), early (n = 81, nCSF = 55) and late bilinguals (n = 97, nCSF = 52) were evaluated. Models adjusted for confounders showed that bilinguals performed better than monolinguals on digits backwards (early-bilinguals p = 0.003), Judgment of Line Orientation (JLO) (early-bilinguals p = 0.018; late-bilinguals p = 0.004), and Trail Making Test-B (late-bilinguals p = 0.047). Early bilingualism was associated with lower CSF total-tau (p = 0.019) and lower prevalence of preclinical AD (NIA-AA classification) (p = 0.02). Bilingualism showed a moderation effect on the relationship between age and CSF AD-biomarkers and the relationship between age and executive function. We conclude that bilingualism contributes to cognitive reserve enhancing executive and visual-spatial functions. For the first time, this study reveals that early bilingualism is associated with more favorable CSF AD-biomarker profile.

    Our objective was to clarify intracranial cerebrospinal fluid (CSF) flow dynamics in normal-pressure hydrocephalus (NPH). Frequency analyses of CSF flow measured with phase-contrast cine MRI were performed. The CSF flow spectra in the aqueduct were determined in patients (n=51) with NPH, brain atrophy or asymptomatic ventricular dilation (VD), and in healthy volunteers (control group; n=25). The changes in CSF flow spectra were also analyzed after intravenous injection of acetazolamide. Moreover, a phase transfer function (PTF) calculated from the spectra of the driving vascular pulsation and CSF flow in the aqueduct were assessed. These values were compared with the pressure volume response (PVR). The amplitude in the NPH group was significantly larger than that in the VD or control group because of a decrease in compliance. The phase in the NPH group was significantly different from that in either the VD or the control group, but no difference was found between the VD and control groups. The amplitude increased in all groups after acetazolamide injection. The PTF in the NPH group was significantly larger than in the control group, and a positive correlation was noted between PTF and PVR. Frequency analyses of CSF flow measured by cine MRI make it possible to noninvasively obtain a more detailed picture of the pathophysiology of NPH. (orig.)

  16. Expression,Purification,and Refolding of Recombinant Fusion Protein Hil-2/Mgm-CSF



    To study the activities of interleukin (IL)-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF) (hIL-2/mGM-CSF).Methods SOE PCR was used to change the linker of the fusion protein for higher activities.The fusion protein was expressed in Escherichia coli (E.coli) BL21 (DE3) in inclusion body (IB) form.After IB was extracted and clarified,it was denatured and purified by affinity chromatography.The protein was refolded by dilution in a L-arginine refolding buffer and refined by anion chromatography.The protein activity was detected by cytokine-dependent cell proliferation assay Results The expression of hlL-2/mGM-CSF in E.coil yielded approximately 20 mg protein/L culture and the purity was about 90%.The specific activities of IL-2 and GM-CSF were 5.4×106 IU/mg and 7.1×106 IU/mg,respectively.Conclusion This research provides important information about the anti-tumor activity of hIL-2/mGM-CSF in vivo,thus facilitating future clinical research on hIL-2/mGM-CSF used in immune therapy.

    Objective: To study the vaccine potency of gene-modified tumor cells. Methods: The EL-4 lymphoma was transduced with recombinant retrovirus containing the murine GM-CSF gene or B7-1 gene. The effect of gene transduction on antitumor immunity was investigated. Results: Flow cytometry analysis showed that expression of their surface marker between wild-type EL-4 cells and gene transduced tumor cells was the same except for CD80 positive in B7-1 gene transduced cells. GM-CSF gene or B7-1 gene transduced EL-4 cells resulted in remarkable loss of tumorigenicity in syngenetic mice. The systemic protective immunity was induced against the challenge with EL-4/wt cells. Therapeutic vaccine with EL-4/GM-CSF or EL/7-1 cells could retard the growth of established early-stage EL-4/wt tumor significantly, but not retard the growth of late-stage EL-4/wt tumor. Irradiated GM-CSF gene transduced EL-4 cells showed strong vaccine effect against EL-4 cell challenge, but irradiated B7-1 gene transduced EL-4 cells showed weak vaccine effect. Remarkable cooperative antitumor effect against EL-4 cell challenge was observed when both irradiated EL-4/GM-CSF and EL-4/B7-1 were inoculated together. Conclusion: GM-CSF gene or B7-1 gene transduced combination of the two kinds of vaccine may have potential application value in human cancer treatment.

  18. Oligosymptomatic neurosyphilis with false negative CSF-VDRL in HIV-infected individuals?

    Malessa, R; Agelink, M W; Hengge, U; Mertins, L; Gastpar, M; Brockmeyer, N H


    The true prevalence of neurosyphilis in HIV-infection is unknown, since a sufficiently sensitive and specific test is lacking. In a prospective study we found reactive serum TPHA and FTA-ABS IgG tests in 95 (31%) of 307 HIV-infected patients. Three of 11 patients with latent syphilis revealed reactive CSF-VDRL tests, six others only demonstrated CSF abnormalities. Resolution of CSF abnormalities during a six month follow up after high dose antibiotic therapy led to the diagnosis of oligosymptomatic or asymptomatic neurosyphilis in all nine patients. Thus, the specificity of the CSF-VDRL was 100%, but the sensitivity was only 33%. The overall prevalence of neurosyphilis was 2.9%, increasing to 9.5% in patients with a reactive serum TPHA. Our study emphasizes the importance of antibiotic therapy for presumptive neurosyphilis in HIV-infected patients with latent syphilis and CSF abnormalities but nonreactive CSF-VDRL tests, even if they are neurologically asymptomatic or present with complaints inconclusive of neurosyphilis.

  19. Cerebral arterial pulsation drives paravascular CSF-interstitial fluid exchange in the murine brain.

    Iliff, Jeffrey J; Wang, Minghuan; Zeppenfeld, Douglas M; Venkataraman, Arun; Plog, Benjamin A; Liao, Yonghong; Deane, Rashid; Nedergaard, Maiken


    CSF from the subarachnoid space moves rapidly into the brain along paravascular routes surrounding penetrating cerebral arteries, exchanging with brain interstitial fluid (ISF) and facilitating the clearance of interstitial solutes, such as amyloid β, in a pathway that we have termed the "glymphatic" system. Prior reports have suggested that paravascular bulk flow of CSF or ISF may be driven by arterial pulsation. However, cerebral arterial pulsation could not be directly assessed. In the present study, we use in vivo two-photon microscopy in mice to visualize vascular wall pulsatility in penetrating intracortical arteries. We observed that unilateral ligation of the internal carotid artery significantly reduced arterial pulsatility by ~50%, while systemic administration of the adrenergic agonist dobutamine increased pulsatility of penetrating arteries by ~60%. When paravascular CSF-ISF exchange was evaluated in real time using in vivo two-photon and ex vivo fluorescence imaging, we observed that internal carotid artery ligation slowed the rate of paravascular CSF-ISF exchange, while dobutamine increased the rate of paravascular CSF-ISF exchange. These findings demonstrate that cerebral arterial pulsatility is a key driver of paravascular CSF influx into and through the brain parenchyma, and suggest that changes in arterial pulsatility may contribute to accumulation and deposition of toxic solutes, including amyloid β, in the aging brain.

  2. Fitting Galaxies on GPUs

    Barsdell, B. R.; Barnes, D. G.; Fluke, C. J.


    Structural parameters are normally extracted from observed galaxies by fitting analytic light profiles to the observations. Obtaining accurate fits to high-resolution images is a computationally expensive task, requiring many model evaluations and convolutions with the imaging point spread function. While these algorithms contain high degrees of parallelism, current implementations do not exploit this property. With ever-growing volumes of observational data, an inability to make use of advances in computing power can act as a constraint on scientific outcomes. This is the motivation behind our work, which aims to implement the model-fitting procedure on a graphics processing unit (GPU). We begin by analysing the algorithms involved in model evaluation with respect to their suitability for modern many-core computing architectures like GPUs, finding them to be well-placed to take advantage of the high memory bandwidth offered by this hardware. Following our analysis, we briefly describe a preliminary implementation of the model fitting procedure using freely-available GPU libraries. Early results suggest a speed-up of around 10× over a CPU implementation. We discuss the opportunities such a speed-up could provide, including the ability to use more computationally expensive but better-performing fitting routines to increase the quality and robustness of fits.

  3. Terahertz dynamic scanning reflectometry of soldier personal protective material

    Rahman, Anis; Mentzer, Mark


    Ballistic characterization of improved materials for Soldier personal protective equipment is an ever-challenging task, requiring precise measurement of materials during ballistic impact. Current dynamic deformation technologies, such as high-speed digital image correlation, and laser velocimetry and vibrometry, are only able to provide surface measurements. However, there is a need to measure the dynamic delamination and mass loss of composite material, allowing calculation of available kinetic energy remaining in the material. A high sensitivity terahertz dynamic scanning reflectometer may be used to measure dynamic surface deformation and delamination characteristics in real-time. A number of crucial parameters can be extracted from the reflectance measurements such as dynamic deformation, propagation velocity, and final relaxation position. As proof of principle, an acrylic plate was struck with a blunt pendulum impactor and dynamic deformation was captured in real-time. Reflectance kinetics was converted to deformation and the velocity was calculated from the kinetics spectrum. Kinetics of a focused pendulum impactor on a steel plate was also acquired, characterizing plate relaxation from maximum deformation to equilibrium with discernible vibrations before reaching stable equilibrium.

  4. The Ewing sarcoma protein (EWS) binds directly to the proximal elements of the macrophage-specific promoter of the CSF-1 receptor (csf1r) gene.

    Hume, David A; Sasmono, Tedjo; Himes, S Roy; Sharma, Sudarshana M; Bronisz, Agnieszka; Constantin, Myrna; Ostrowski, Michael C; Ross, Ian L


    Many macrophage-specific promoters lack classical transcriptional start site elements such as TATA boxes and Sp1 sites. One example is the CSF-1 receptor (CSF-1R, CD115, c-fms), which is used as a model of the transcriptional regulation of macrophage genes. To understand the molecular basis of start site recognition in this gene, we identified cellular proteins binding specifically to the transcriptional start site (TSS) region. The mouse and human csf1r TSS were identified using cap analysis gene expression (CAGE) data. Conserved elements flanking the TSS cluster were analyzed using EMSAs to identify discrete DNA-binding factors in primary bone marrow macrophages as candidate transcriptional regulators. Two complexes were identified that bind in a highly sequence-specific manner to the mouse and human TSS proximal region and also to high-affinity sites recognized by myeloid zinc finger protein 1 (Mzf1). The murine proteins were purified by DNA affinity isolation from the RAW264.7 macrophage cell line and identified by mass spectrometry as EWS and FUS/TLS, closely related DNA and RNA-binding proteins. Chromatin immunoprecipitation experiments in bone marrow macrophages confirmed that EWS, but not FUS/TLS, was present in vivo on the CSF-1R proximal promoter in unstimulated primary macrophages. Transfection assays suggest that EWS does not act as a conventional transcriptional activator or repressor. We hypothesize that EWS contributes to start site recognition in TATA-less mammalian promoters.

  5. A randomized phase II study of stem cell mobilization with cyclophosphamide+G-CSF or G-CSF alone after lenalidomide-based induction in multiple myeloma

    Silvennoinen, R; Anttila, P; Säily, M; Lundan, T; Heiskanen, J; Siitonen, T M; Kakko, S; Putkonen, M; Ollikainen, H; Terävä, V; Kutila, A; Launonen, K; Räsänen, A; Sikiö, A; Suominen, M; Bazia, P; Kananen, K; Selander, T; Kuittinen, T; Remes, K; Jantunen, E


    The most common means of mobilizing autologous stem cells is G-CSF alone or combined with cyclophosphamide (CY) to obtain sufficient CD34+ cells for one to two transplants. There are few prospective, randomized studies investigating mobilization regimens in multiple myeloma (MM), especially after lenalidomide-based induction. We designed this prospective, randomized study to compare low-dose CY 2 g/m2+G-CSF (arm A) and G-CSF alone (arm B) after lenalidomide-based up-front induction in MM. Of the 80 initially randomized patients, 69 patients were evaluable, 34 and 35 patients in arms A and B, respectively. The primary end point was the proportion of patients achieving a yield of ⩾3 × 106/kg CD34+ cells with 1−2 aphereses, which was achieved in 94% and 77% in arms A and B, respectively (P=0.084). The median number of aphereses needed to reach the yield of ⩾3 × 106/kg was lower in arm A than in arm B (1 vs 2, P=0.035). Two patients needed plerixafor in arm A and five patients in arm B (P=0.428). Although CY-based mobilization was more effective, G-CSF alone was successful in a great majority of patients to reach the defined collection target after three cycles of lenalidomide-based induction.

    Rappole, Catherine; Grier, Tyson; Anderson, Morgan K; Hauschild, Veronique; Jones, Bruce H


    To investigate the effects of age, aerobic fitness, and body mass index (BMI) on injury risk in operational Army soldiers. Retrospective cohort study. Male soldiers from an operational Army brigade were administered electronic surveys regarding personal characteristics, physical fitness, and injuries occurring over the last 12 months. Injury risks were stratified by age, 2-mile run time, and BMI. Analyses included descriptive incidence, a Mantel-Haenszel χ(2) test to determine trends, a multivariable logistic regression to determine factors associated with injury, and a one-way analysis of variance (ANOVA). Forty-seventy percent of 1099 respondents reported at least one injury. A linear trend showed that as age, 2-mile run time, and BMI increased, so did injury risk (prisk factors were older age (odd ratio (OR) 30years-35years/≤24years=1.25, 95%CI: 1.08-2.32), (OR≥36years/≤24years=2.05, 95%CI: 1.36-3.10), and slow run times (OR≥15.9min/≤13.9min=1.91, 95%CI: 1.28-2.85). An ANOVA showed that both run times and BMI increased with age. The stratified analysis and the multivariable logistic regression suggested that older age and poor aerobic fitness are stronger predictors of injury than BMI.

    Shelef, Leah; Ayzen, Evyatar; Yavnai, Nirit; Fruchter, Eyal; Sarid, Orly


    Suicidal ideation is a risk factor for suicide attempt. The aim of the present study is to compare suicidal ideation of different groups with different distress. 100 soldiers, aged 18-21, divided into four research cohorts: soldiers who had carried out a suicide attempt (n = 40); soldiers with a psychiatric diagnosis (n = 20); soldiers having high severity adjustment difficulties (n = 20); and a control group of soldiers, having neither a history of mental health diagnosis, nor adjustment difficulties (n = 20). All completed the suicide ideation scale. Half of the attempters had a psychiatric diagnosis (depression or anxiety) on the day of their enlistment and 37.5 % of them had a specified personality disturbance. The attempters were characterized by previously-attempted suicide (p < .01). The lowest mean values (M = 1.95, SD = .67) were among the attempter (F = 3.173, df = 3, p = .02) in motivation for military service. The variable expressing low motivation for military service was the sole predictor of suicide ideation (p = .032). Early diagnosis facilitated better monitoring by military mental health officers.

  8. Cigarette smoking and subsequent risk of suicidal ideation among National Guard Soldiers

    Goodwin, Renee D; Prescott, Marta; Tamburrino, Marijo; Calabrese, Joseph R.; Liberzon, Israel; Galea, Sandro


    BACKGROUND Suicide rates are alarmingly high among military personnel, and particularly Army National Guard soldiers. Smoking is also disproportionately common in the military. In this study, we intend to investigate the relationship between cigarette smoking and suicidal ideation among a representative sample of national guard soldiers. METHODS A representative sample of Ohio Army National Guard soldiers were followed prospectively and information was gathered on smoking, suicidal ideation and depression at baseline and one year later. RESULTS Smoking at baseline was associated with significantly increased likelihood of suicidal ideation at follow-up (OR=2.0 (1.3, 3.2)). This association persisted after adjusting for demographics and history of depression at baseline, but was no longer statistically significant after adjusting for depression at follow-up. LIMITATIONS Measurement of smoking was somewhat limited. CONCLUSIONS Army National Guard soldiers who smoke have a greater risk of subsequent suicidal ideation. Depression concurrent with suicidal ideation appears to explain this relationship. If these results are replicated, screening of soldiers who smoke may be recommended as a proactive step towards mitigating the high risk of suicide in military personnel. PMID:23141668

    Beals, Kim; Darnell, Matthew E; Lovalekar, Mita; Baker, Rachel A; Nagai, Takashi; San-Adams, Thida; Wirt, Michael D


    The purpose of this study was to evaluate the nutrient intake of male and female Soldiers in the 101 st Airborne Division (Air Assault) compared to sports nutrition standards for athletes, and to identify suboptimal eating characteristics that may impair physical performance and jeopardize military readiness. Male and female Soldiers from the 101 st Airborne Division (Air Assault) completed a 24-hour dietary recall and nutrition history questionnaire before anthropometric and body composition measurements were taken. Compared to sports nutrition guidelines, Soldiers of the 101 st under consume carbohydrates (males: 3.9 ± 2.0 vs. 5.0 g/kg, p < 0.001; females: 4.0 ± 2.1 vs. 5.0 g/kg, p = 0.001), male Soldiers eat too much fat (32.4% of kcal vs. <30% of kcal, p = 0.000) and saturated fat (males: 10.5 ± 3.9% of kcal vs. 10.0% of kcal, p = 0.044), and both males and females follow a meal pattern that may not optimize energy availability throughout the day. Eating too much fat and under fueling carbohydrate may negatively impact the adaptations to physical training and compromise overall health. Although Soldiers continue to participate in arduous training programs, future research should be aimed at determining the energy and macronutrient needs to fuel and recover from specific types of military training.

  10. Dietary habits and normal body mass index association in Chilean soldiers

    Samuel Durán-Agüero


    Full Text Available Introduction: Eating habits of various age and professional groups has been evaluated. However, there is little information on the dietary habits of soldiers. The aim of this study is to associate eating habits with the normal body mass index (BMI in Chilean soldiers from Buin Regiment. Material and Methods: 412 soldiers were evaluated. Food survey and anthropometric evaluation was applied to each soldier. It was considered a normal BMI when the subject was between 18.5-24.9kg/m2, overweight between 25.0-29.9kg/m2 and obesity ≥30.0kg/m2, according to the WHO recommendations. Results: 41.2% of the soldiers show a normal BMI, 43.1% present overweight and 15.7% exhibit obesity. Only 5% meet the dairy and fruit Chilean recommendations, however almost 40% of them consume 1time/day (OR:0.41; IC95%:0.19-0.88 and legume consumption (>1time/week (OR:0.29; IC95%:0.14-0.60. Conclusions: A low consumption of dairy products, fruits, vegetables and legumes is noted, and a high consumption of sweetened beverages. In addition, intake of dairy products and legumes is related with a normal BMI.

  11. A soldier suffering from PTSD, treated by controlled stress exposition using virtual reality and behavioral training.

    Tworus, Radosław; Szymanska, Sylwia; Ilnicki, Stanisław


    This article presents a case of posttraumatic stress disorder (PTSD) in a 30-year-old soldier of the Polish Military Contingent in Iraq who narrowly escaped death three times. The first time occurred when during a change of guard he was unintentionally shot by his colleague. The projectile penetrated the victim's helmet, slid along its internal shell curvature, and left the shell causing only a scratch on the scalp skin. Another traumatic event was experienced by the soldier a month after the first incident. As a guard of honor, he was "shot" in the same rear head area with a cap of a cream tube, inadvertently stepped on by a colleague. The third event occurred a couple of days later, during a rocket attack on the Diwaniyah base. After this incident the soldier was evacuated to the Clinic of Psychiatry and Combat Stress in Warsaw. Multiform PTSDs that developed in this soldier are described in this work. The course of his comprehensive therapy during his two stays, with a total duration of 8 months, in the clinic is discussed. Also, a detailed description of the therapy controlled exposition to combat stressors in virtual reality (VR), supplemented with behavioral training consisting of desensitization of an aversive reaction to contact with a weapon at a shooting range is presented. The comprehensive treatment activities resulted in full remission of the PTSD symptoms. The soldier continues his service in a logistic support unit.

  12. Associations of childhood bullying victimization with lifetime suicidal behaviors among new U.S. Army soldiers.

    Campbell-Sills, Laura; Kessler, Ronald C; Ursano, Robert J; Rosellini, Anthony J; Afifi, Tracie O; Colpe, Lisa J; Heeringa, Steven G; Nock, Matthew K; Sampson, Nancy A; Sareen, Jitender; Schoenbaum, Michael; Sun, Xiaoying; Jain, Sonia; Stein, Murray B


    Prior studies have documented associations of childhood bullying victimization with suicidal behaviors. However, many failed to adjust for concomitant risk factors and none investigated this relationship in military personnel. This study aimed to estimate independent associations of childhood bullying victimization with suicidal behaviors among U.S. Army soldiers. Soldiers reporting for basic training completed a cross-sectional survey assessing mental disorders, suicidal behaviors, and childhood adversities including two types of bullying victimization: (1) Physical Assault/Theft and (2) Bullying Comments/Behaviors. Associations of childhood bullying experiences with suicidal behaviors were estimated using discrete-time survival analysis of person-year data from 30,436 soldiers. Models adjusted for sociodemographic factors, childhood maltreatment by adults, and mental disorders. After comprehensive adjustment for other risk factors, more frequent Physical Assault/Theft by peers during childhood was associated with increased odds of lifetime suicidal ideation (adjusted odds ratio [AOR] = 1.18, 95% CI: 1.11-1.26, P soldiers. Exposure to Bullying Comments/Behaviors during childhood is associated with progression from suicidal ideation to plan. Improved recognition of these relationships may inform risk mitigation interventions for soldiers. © 2017 Wiley Periodicals, Inc.

  13. Prevalence and risk of cysticercosis and taeniasis in an urban population of soldiers and their relatives.

    García-García, M L; Torres, M; Correa, D; Flisser, A; Sosa-Lechuga, A; Velasco, O; Meza-Lucas, A; Plancarte, A; Avila, G; Tapia, R; Aguilar, L; Mandujano, A; Alcántara, I; Morales, Z; Salcedo, A; Mañon, M D; Valdespino-Gomez, J L


    To determine markers of Taenia solium transmission and risk factors in an urban community, we studied 1,000 soldiers from a military camp in Mexico City and their relatives. Serum samples were used to detect antigens and antibodies and fecal specimens were examined for Taenia coproantigens and helminth eggs. Prevalences of 12.2% and 5.8% for cysticercosis were found among soldiers and their relatives, respectively. Taeniasis was found in 0.5% and none of the groups, respectively. Relatives of soldiers positive for cysticercosis and taeniasis markers ate more pork from street stores than restaurants or markets compared with relatives of soldiers without these indicators of infection. Also, 12.0% of the relatives of positive soldiers had a history of expelling tapeworm proglottids in the feces in contrast to 3.7% of the family members of the control group. Prevalence values and risk factors in this urban population are similar to those of previous studies performed in rural populations.

  14. Postdeployment reintegration experiences of female soldiers from national guard and reserve units in the United States.

    Kelly, Patricia J; Berkel, LaVerne A; Nilsson, Johanna E


    Women are an integral part of Reserve and National Guard units and active duty armed forces of the United States. Deployment to conflict and war zones is a difficult experience for both soldiers and their families. On return from deployment, all soldiers face the challenge of reintegration into family life and society, but those from the National Guard and Reserve units face the additional challenge of reintegration in relative isolation from other soldiers. There is limited research about the reintegration experiences of women and the functioning of the families during reintegration following deployment. The goal was to document postdeployment family reintegration experiences of women in the National Guard. Semistructured interviews were conducted with 42 female members of Midwestern National Guard units. Directed content analysis was used to identify categories of experiences related to women's family reintegration. Five categories of postdeployment experience for female soldiers and their families were identified: Life Is More Complex, Loss of Military Role, Deployment Changes You, Reestablishing Partner Connections, and Being Mom Again. The categories reflected individual and family issues, and both need to be considered when soldiers and their families seek care. Additional research is needed to fully understand the specific impact of gender on women's reintegration.

  15. Relationship of PTSD Symptoms With Combat Exposure, Stress, and Inflammation in American Soldiers.

    Groer, Maureen W; Kane, Bradley; Williams, S Nicole; Duffy, Allyson


    Posttraumatic stress disorder (PTSD) is of great concern in veterans. PTSD usually occurs after a person is exposed to death, threatened death, actual or threatened serious injury, or actual or threatened sexual violence. Active duty soldiers deployed to war zones are at risk for PTSD. Psychoneuroimmunological theory predicts that PTSD, depression, and stress can lead to low-grade, chronic inflammation. We asked whether there were relationships between PTSD symptoms and chronic stress, depression and inflammation in active duty U.S. soldiers. We enrolled 52 active duty enlisted and reservist soldiers in a cross-sectional study while they participated in a week of military training in fall 2011. They completed a demographic questionnaire, the Center for Epidemiological Studies-Depression Scale, the Combat Exposure Scale, and the PTSD symptom Checklist-Military version (PCL-M). Blood samples were taken for analysis of cytokines and C-reactive protein (CRP). Hair samples shaved from the forearm were measured for cortisol. Of the soldiers, 11 had PCL-M scores in the moderate to severe range. Regression analysis demonstrated that depression and war zone deployment were strong predictors of PTSD symptoms. CRP and hair cortisol were correlated with each other and with depression and PTSD symptoms. These results suggest relationships among war zone deployment, depression, and PTSD. Chronic stress associated with depression, PTSD, and war zone experiences may be related to inflammation in active duty soldiers.

  16. Recombinant human IL-3 and G-CSF act synergistically in stimulating the growth of acute myeloid leukemia cells.

    Pébusque, M J; Faÿ, C; Lafage, M; Sempéré, C; Saeland, S; Caux, C; Mannoni, P


    The effects of combinations of recombinant human growth factors (colony-stimulating factor (CSF], interleukin 3 (IL-3), granulocyte-macrophage colony-stimulating factor (GM-CSF), and granulocyte colony stimulating factor (G-CSF) for inducing proliferation of leukemic cells were compared in 27 acute myeloid leukemias (AMLs). While functional heterogeneity of AML was clearly shown, we further demonstrated that optimal growth may be obtained with combinations of CSF. The most striking feature was that, in both suspension and semisolid cultures, IL-3 and G-CSF acted synergistically in supporting AML cell proliferation except in cases for which G-CSF was found to be an inhibitory factor. In the majority of cases, the proliferative effects of the IL-3 and GM-CSF combination were significantly higher than the most potent of either factor present alone in the cultures. Finally, preincubation with IL-3 greatly potentiated the responsiveness of AML cells to subsequent addition of either GM-CSF or G-CSF. These results indicate that AML cells respond to growth factor in the same way as normal hemopoietic cells and that stimulation by a second late-acting growth factor such as G-CSF is also required to yield optimal growth.

  18. CSF and brain structural imaging markers of the Alzheimer's pathological cascade.

    Xianfeng Yang

    Full Text Available Cerebral spinal fluid (CSF and structural imaging markers are suggested as biomarkers amended to existing diagnostic criteria of mild cognitive impairment (MCI and Alzheimer's disease (AD. But there is no clear instruction on which markers should be used at which stage of dementia. This study aimed to first investigate associations of the CSF markers as well as volumes and shapes of the hippocampus and lateral ventricles with MCI and AD at the baseline and secondly apply these baseline markers to predict MCI conversion in a two-year time using the Alzheimer's Disease Neuroimaging Initiative (ADNI cohort. Our results suggested that the CSF markers, including Aβ42, t-tau, and p-tau, distinguished MCI or AD from NC, while the Aβ42 CSF marker contributed to the differentiation between MCI and AD. The hippocampal shapes performed better than the hippocampal volumes in classifying NC and MCI, NC and AD, as well as MCI and AD. Interestingly, the ventricular volumes were better than the ventricular shapes to distinguish MCI or AD from NC, while the ventricular shapes showed better accuracy than the ventricular volumes in classifying MCI and AD. As the CSF markers and the structural markers are complementary, the combination of them showed great improvements in the classification accuracies of MCI and AD. Moreover, the combination of these markers showed high sensitivity but low specificity for predicting conversion from MCI to AD in two years. Hence, it is feasible to employ a cross-sectional sample to investigate dynamic associations of the CSF and imaging markers with MCI and AD and to predict future MCI conversion. In particular, the volumetric information may be good for the early stage of AD, while morphological shapes should be considered as markers in the prediction of MCI conversion to AD together with the CSF markers.

  19. Fibronectin induces macrophage migration through a SFK-FAK/CSF-1R pathway.

    Digiacomo, Graziana; Tusa, Ignazia; Bacci, Marina; Cipolleschi, Maria Grazia; Dello Sbarba, Persio; Rovida, Elisabetta


    Integrins, following binding to proteins of the extracellular matrix (ECM) including collagen, laminin and fibronectin (FN), are able to transduce molecular signals inside the cells and to regulate several biological functions such as migration, proliferation and differentiation. Besides activation of adaptor molecules and kinases, integrins transactivate Receptor Tyrosine Kinases (RTK). In particular, adhesion to the ECM may promote RTK activation in the absence of growth factors. The Colony-Stimulating Factor-1 Receptor (CSF-1R) is a RTK that supports the survival, proliferation, and motility of monocytes/macrophages, which are essential components of innate immunity and cancer development. Macrophage interaction with FN is recognized as an important aspect of host defense and wound repair. The aim of the present study was to investigate on a possible cross-talk between FN-elicited signals and CSF-1R in macrophages. FN induced migration in BAC1.2F5 and J774 murine macrophage cell lines and in human primary macrophages. Adhesion to FN determined phosphorylation of the Focal Adhesion Kinase (FAK) and Src Family Kinases (SFK) and activation of the SFK/FAK complex, as witnessed by paxillin phosphorylation. SFK activity was necessary for FAK activation and macrophage migration. Moreover, FN-induced migration was dependent on FAK in either murine macrophage cell lines or human primary macrophages. FN also induced FAK-dependent/ligand-independent CSF-1R phosphorylation, as well as the interaction between CSF-1R and β1. CSF-1R activity was necessary for FN-induced macrophage migration. Indeed, genetic or pharmacological inhibition of CSF-1R prevented FN-induced macrophage migration. Our results identified a new SFK-FAK/CSF-1R signaling pathway that mediates FN-induced migration of macrophages.

  20. Lymphatic Endothelial Cells Produce M-CSF, Causing Massive Bone Loss in Mice.

    Wang, Wensheng; Wang, Hua; Zhou, Xichao; Li, Xing; Sun, Wen; Dellinger, Michael; Boyce, Brendan F; Xing, Lianping


    Gorham-Stout disease (GSD) is a rare bone disorder characterized by aggressive osteolysis associated with lymphatic vessel invasion within bone marrow cavities. The etiology of GSD is not known, and there is no effective therapy or animal model for the disease. Here, we investigated if lymphatic endothelial cells (LECs) affect osteoclasts (OCs) to cause a GSD osteolytic phenotype in mice. We examined the effect of a mouse LEC line on osteoclastogenesis in co-cultures. LECs significantly increased receptor activator of NF-κB ligand (RANKL)-mediated OC formation and bone resorption. LECs expressed high levels of macrophage colony-stimulating factor (M-CSF), but not RANKL, interleukin-6 (IL-6), and tumor necrosis factor (TNF). LEC-mediated OC formation and bone resorption were blocked by an M-CSF neutralizing antibody or Ki20227, an inhibitor of the M-CSF receptor, c-Fms. We injected LECs into the tibias of wild-type (WT) mice and observed massive osteolysis on X-ray and micro-CT scans. Histology showed that LEC-injected tibias had significant trabecular and cortical bone loss and increased OC numbers. M-CSF protein levels were significantly higher in serum and bone marrow plasma of mice given intra-tibial LEC injections. Immunofluorescence staining showed extensive replacement of bone and marrow by podoplanin+ LECs. Treatment of LEC-injected mice with Ki20227 significantly decreased tibial bone destruction. In addition, lymphatic vessels in a GSD bone sample were stained positively for M-CSF. Thus, LECs cause bone destruction in vivo in mice by secreting M-CSF, which promotes OC formation and activation. Blocking M-CSF signaling may represent a new therapeutic approach for treatment of patients with GSD. Furthermore, tibial injection of LECs is a useful mouse model to study GSD. © 2017 American Society for Bone and Mineral Research.

  1. Granulocyte macrophage colony stimulating factor (GM-CSF biological actions on human dermal fibroblasts

    S Montagnani


    Full Text Available Fibroblasts are involved in all pathologies characterized by increased ExtraCellularMatrix synthesis, from wound healing to fibrosis. Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF is a cytokine isolated as an hemopoietic growth factor but recently indicated as a differentiative agent on endothelial cells. In this work we demonstrated the expression of the receptor for GM-CSF (GMCSFR on human normal skin fibroblasts from healthy subjects (NFPC and on a human normal fibroblast cell line (NHDF and we try to investigate the biological effects of this cytokine. Human normal fibroblasts were cultured with different doses of GM-CSF to study the effects of this factor on GMCSFR expression, on cell proliferation and adhesion structures. In addition we studied the production of some Extra-Cellular Matrix (ECM components such as Fibronectin, Tenascin and Collagen I. The growth rate of fibroblasts from healthy donors (NFPC is not augmented by GM-CSF stimulation in spite of increased expression of the GM-CSFR. On the contrary, the proliferation of normal human dermal fibroblasts (NHDF cell line seems more influenced by high concentration of GM-CSF in the culture medium. The adhesion structures and the ECM components appear variously influenced by GM-CSF treatment as compared to fibroblasts cultured in basal condition, but newly only NHDF cells are really induced to increase their synthesis activity. We suggest that the in vitro treatment with GM-CSF can shift human normal fibroblasts towards a more differentiated state, due or accompanied by an increased expression of GM-CSFR and that such “differentiation” is an important event induced by such cytokine.

  2. Role of CSF-CRP as a bedside diagnostic test in children with meningitis.

    Piyush Sadat


    Full Text Available Meningitis is a formidable illness with high mortality and morbidity in India. Delay in distinguishing pyogenic meningitis from tuberculous and viral meningitis and delay in starting therapy on one hand and irrational use of antibiotics on the other hand may have irrevocable consequences, so, early diagnosis and appropriate treatment of pyogenic meningitis is very vital to prevent permanent neurological deficits. Detection of C-reative protein in CSF is a bed side rapid diagnostic test to distinguish pyogenic from tuberculous and viral meningitis. So, present study was undertaken to study the usefulness of c-reactive protein in CSF as a rapid diagnostic test in differentiating pyogenic from tuberculous and viral meningitis.This study was conducted at Smt Shardaben Hospital from Sept-2008 to Nov-2010. Total 150 cases admitted in paediatric department and neonates admitted to the sick nursery suspected of having meningitis were included. Samples of CSF were taken for bed side diagnostic test of CSF-CRP. The major advantage of this method is rapid two minute reaction time. Our study revealed that out of 150 cases of suspected meningitis 64 (42.66% patient were having meningitis out of which 18 (12% patients were diagnosed as pyogenic meningitis and CSF CRP was positive in 10 (55.55 % patients out of 18 pyogenic meningitis patients and CSF-CRP was negative in all other groups Applying chisquare test, correlation between CSF-CRP positivity and pyoganic meningitis was highly significant (x2 = 31(i.e.> 3.84

  5. Alternative Astronomical FITS imaging

    Varsaki, Eleni E; Fotopoulos, Vassilis; Skodras, Athanassios N


    Astronomical radio maps are presented mainly in FITS format. Astronomical Image Processing Software (AIPS) uses a set of tables attached to the output map to include all sorts of information concerning the production of the image. However this information together with information on the flux and noise of the map is lost as soon as the image of the radio source in fits or other format is extracted from AIPS. This information would have been valuable to another astronomer who just uses NED, for example, to download the map. In the current work, we show a method of data hiding inside the radio map, which can be preserved under transformations, even for example while the format of the map is changed from fits to other lossless available image formats.

  6. Fitting Galaxies on GPUs

    Barsdell, Benjamin R; Fluke, Christopher J


    Structural parameters are normally extracted from observed galaxies by fitting analytic light profiles to the observations. Obtaining accurate fits to high-resolution images is a computationally expensive task, requiring many model evaluations and convolutions with the imaging point spread function. While these algorithms contain high degrees of parallelism, current implementations do not exploit this property. With evergrowing volumes of observational data, an inability to make use of advances in computing power can act as a constraint on scientific outcomes. This is the motivation behind our work, which aims to implement the model-fitting procedure on a graphics processing unit (GPU). We begin by analysing the algorithms involved in model evaluation with respect to their suitability for modern many-core computing architectures like GPUs, finding them to be well-placed to take advantage of the high memory bandwidth offered by this hardware. Following our analysis, we briefly describe a preliminary implementa...

  7. Fitting the Phenomenological MSSM

    AbdusSalam, S S; Quevedo, F; Feroz, F; Hobson, M


    We perform a global Bayesian fit of the phenomenological minimal supersymmetric standard model (pMSSM) to current indirect collider and dark matter data. The pMSSM contains the most relevant 25 weak-scale MSSM parameters, which are simultaneously fit using `nested sampling' Monte Carlo techniques in more than 15 years of CPU time. We calculate the Bayesian evidence for the pMSSM and constrain its parameters and observables in the context of two widely different, but reasonable, priors to determine which inferences are robust. We make inferences about sparticle masses, the sign of the $\\mu$ parameter, the amount of fine tuning, dark matter properties and the prospects for direct dark matter detection without assuming a restrictive high-scale supersymmetry breaking model. We find the inferred lightest CP-even Higgs boson mass as an example of an approximately prior independent observable. This analysis constitutes the first statistically convergent pMSSM global fit to all current data.

  8. Identification of the Upward Movement of Human CSF In Vivo and its Relation to the Brain Venous System.

    Dreha-Kulaczewski, Steffi; Joseph, Arun A; Merboldt, Klaus-Dietmar; Ludwig, Hans-Christoph; Gärtner, Jutta; Frahm, Jens


    CSF flux is involved in the pathophysiology of neurodegenerative diseases and cognitive impairment after traumatic brain injury, all hallmarked by the accumulation of cellular metabolic waste. Its effective disposal via various CSF routes has been demonstrated in animal models. In contrast, the CSF dynamics in humans are still poorly understood. Using novel real-time MRI, forced inspiration has been identified recently as a main driving force of CSF flow in the human brain. Exploiting technical advances toward real-time phase-contrast MRI, the current work analyzed directions, velocities, and volumes of human CSF flow within the brain aqueduct as part of the internal ventricular system and in the spinal canal during respiratory cycles. A consistent upward CSF movement toward the brain in response to forced inspiration was seen in all subjects at the aqueduct, in 11/12 subjects at thoracic level 2, and in 4/12 subjects at thoracic level 5. Concomitant analyses of CSF dynamics and cerebral venous blood flow, that is, in epidural veins at cervical level 3, uniquely demonstrated CSF and venous flow to be closely communicating cerebral fluid systems in which inspiration-induced downward flow of venous blood due to reduced intrathoracic pressure is counterbalanced by an upward movement of CSF. The results extend our understanding of human CSF flux and open important clinical implications, including concepts for drug delivery and new classifications and therapeutic options for various forms of hydrocephalus and idiopathic intracranial hypertension.SIGNIFICANCE STATEMENT Effective disposal of brain cellular waste products via CSF has been demonstrated repeatedly in animal models. However, CSF dynamics in humans are still poorly understood. A novel quantitative real-time MRI technique yielded in vivo CSF flow directions, velocities, and volumes in the human brain and upper spinal canal. CSF moved upward toward the head in response to forced inspiration. Concomitant analysis

  9. The universal Higgs fit

    Giardino, P. P.; Kannike, K.; Masina, I.;


    We perform a state-of-the-art global fit to all Higgs data. We synthesise them into a 'universal' form, which allows to easily test any desired model. We apply the proposed methodology to extract from data the Higgs branching ratios, production cross sections, couplings and to analyse composite H...... as an alternative to the Higgs, and disfavour fits with negative Yukawa couplings. We derive for the first time the SM Higgs boson mass from the measured rates, rather than from the peak positions, obtaining M-h = 124.4 +/- 1.6 GeV....

  10. The Antecedents of Extra - Role Organizational Behaviors: A Qualitative Research on Soldier

    Ali Murat Alparslan


    Full Text Available The aim of this study is to reveal the antecedents of extra-role behaviors carried out by the soldiers, who serve in the army without having any financial expectation and have to stay in the barracks due to their compulsory military service. For this purpose, an exploratory research was conducted, in which the detailed interview method was applied on 14 soldiers, who had a certificate of appreciation from their commanders and said to exhibit extra-role behaviors by their commanders. The findings have indicated that exhibited extra-role behaviors were highly related with friendship. Other behaviors are tasks in company, training other soldiers, learning new things, and using the knowledge and skills from civil life in army. When the reasons of these behaviors are examined in detail, it can be seen that the most important factor is friendship, followed by personality, being liked and esteemed by commanders, reciprocity, institute’s success and patriotism

  11. Personal values in soldiers after military deployment: associations with mental health and resilience

    Peter Zimmermann


    Full Text Available Background: After military deployment, soldiers are at an increased risk of developing posttraumatic psychiatric disorders. The correlation of personal values with symptoms, however, has not yet been examined within a military context. Method: Schwartz's Portrait Values Questionnaire (PVQ, the Posttraumatic Stress Diagnostic Scale (PDS, and the 11-item version of the Resilience Scale (RS-11 were completed by 117 soldiers of the German Armed Forces who had recently been deployed to Afghanistan (n=40 undergoing initial psychiatric treatment, n=77 untreated. Results: Logistic regression showed that the value types of hedonism (−, power (−, tradition (+, and universalism (+ were significantly correlated with the probability and severity of PTSD and whether the participant was in treatment or not. The effects were partially mediated by the RS-11 scale values. Conclusions: Value types seem to be associated with psychiatric symptoms in soldiers after deployment. These results could contribute to the further development of therapeutic approaches.

    Li, Wu; Li, Qing; Zheng, Longyu; Wang, Yuanyuan; Zhang, Jibin; Yu, Ziniu; Zhang, Yanlin


    Bioenergy has become attractive as alternatives of gradually exhausted fossil fuel. Obtaining high grade bioenergy from lignocellulose is attractive that can gradually meet the demand. This study reported biogas and biodiesel were produced from corncob by a two-step bioprocess, biogas was produced from corncob by anaerobic fermentation, then biogas residue was converted by black soldier fly larvae, and then biodiesel was produced from larvae grease. 86.70 L biogas was obtained from 400 g corncob with the accumulation of biogas yield of 220.71 mL/g VS(added) by anaerobic digestion. Besides, 3.17 g of biodiesel was produced from grease after inoculating black soldier fly larvae into 400 g biogas residue. Meanwhile, the results showed that the addition of black soldier fly larvae could be effective for the degradation of lignocellulose and the accumulation of grease.

  13. Relationship of Life Satisfaction and Job Satisfaction among Pakistani Army Soldiers

    Summaira Naz


    Full Text Available The present study had two main objectives; first, to discover the relationships between job satisfaction and life satisfaction in Pakistani army soldiers, second, to find out the age, salary, marital status, and education differences on job satisfaction and life satisfaction in Pakistani army soldiers. In the present study two questionnaires; Job Satisfaction Scale JSS (Macdonald & Maclntyre, 1997 and Satisfaction With Life Scale (Diener, et al., 1985; were administered to a sample (N=400 along with a demographic sheet. The results of the study revealed a significant positive correlation between job satisfaction and life satisfaction of Pakistani army soldiers. The findings of the study also showed a significant age, education, salary, and marital status differences in job satisfaction and life satisfaction. Age, marital status, and salary variables had positive correlation with job satisfaction and life satisfaction but education had a negative association with job satisfaction and life satisfaction

  14. Military morality transformed: weapons and soldiers on the nineteenth-century battlefield.

    Phillips, Gervase


    The increased lethality of nineteenth-century “arms of precision” caused military formations to disperse in combat, transforming the ordinary soldier from a near automaton, drilled to deliver random fire under close supervision, into a moral agent who exercised a degree of choice about where, when, and how to fire his weapon. The emerging autonomy of the soldier became a central theme in contemporary tactical debates, which struggled to reconcile the desire for discipline with the individual initiative necessary on the battlefield. This tactical conundrum offers revealing insights about human aggression and mass violence. Its dark legacy was the propagation of military values into civilian society, thus paving the way for the political soldiers of the twentieth century.

  15. Evaluation of Low Energy Pack Ration by Short Term Feeding to Soldiers

    K.R. Viswanathan


    Full Text Available Fifteen soldiers were fed, during intensive training including a patrol operation, on low energy pack(LEP ration for eight days for evaluating the suitability of the LEP ration providing 2100 kcal. Measurements were taken for body weight, skinfold thickness, blood cholesterol and phospholipids, glucose tolerance, and a battery of physical performance tests. Data were compared with another two identical groups of soldiers fed either a normal energy fresh(NEF ration(3631 kcal. The group on LEP ration lost 1.2 kg in body weight while the other two groups maintained their body weight with marginal fluctuations. Besides the slight loss of weight and a transient impairment of glucose tolerance, the subjects on LEP ration showed no other abnormality in any of the parameters studied. The study revealed that the LEP ration was suitable for feeding soldiers for short durations.

  16. Prazosin treatment of trauma nightmares and sleep disturbance in soldiers deployed in Iraq.

    Calohan, Jess; Peterson, Kris; Peskind, Elaine R; Raskind, Murray A


    Trauma nightmares and sleep disturbance impair combat soldiers' functioning. The alpha-1 adrenoreceptor antagonist prazosin has been demonstrated effective for these symptoms in Vietnam veterans. Thirteen soldiers seeking relief from distressing trauma nightmares impairing military function in northern Iraq in 2006 received prazosin alone or in combination with other psychotropics. Mean prazosin dose was 4.1 (SD = 2.2) mg before bed. Six soldiers improved markedly and 3 moderately on the Clinical Global Impression of Change Ratings of distressing dreams decreased from an average of 7.0 (SD = 0.7) to 2.9 (SD = 3.0, p < .001) and those of disturbed sleep from 6.7 (SD = 0.9) to 3.7 (SD = 2.4, p < .001). Prazosin appears effective and well tolerated in the desert warfare environment.

  17. Identification of Missing Norwegian World War II Soldiers, in Karelia Russia.

    Morild, Inge; Hamre, Stian S; Huel, Rene; Parsons, Thomas J


    This article presents the multidisciplinary effort in trying to identify the skeletal remains of 100 Norwegian soldiers serving in the German army, killed in Karelia Russia in 1944, from the recovery of the remains through the final identification using DNA. Of the 150 bone samples sent for DNA testing, 93 DNA profiles were obtained relating to 57 unique individuals. The relatives could not be directly contacted as the soldiers were considered as traitors to Norway; therefore, only 45 reference samples, relating to 42 cases of the missing, were donated. DNA matches for 14 soldiers and 12 additional body part re-associations for these individuals were found. Another 24 bone samples were re-associated with 16 individuals, but no familial match was found. More than six decades after the end of WWII, DNA analysis can significantly contribute to the identification of the remains.

  18. The chief seat of mischief: soldier's heart in the First World War.

    Dyde, Sean


    Soldier's heart was a medico-psychiatric condition that was first documented during the American Civil War. This condition affected British and American soldiers during the late-nineteenth and early-twentieth centuries; doctors recorded patients experiencing palpitations, breathlessness, headaches, and praecordial pain among other symptoms. While the number of cases of this disorder reached its peak in the First World War, it disappeared shortly afterwards. Based on an analysis of experimental results published in generalist and specialized medical journals as well as the correspondence between physicians and researchers that these journals maintained, this study challenges the view that soldier's heart disappeared because doctors realized that the disorder was, in fact, psychosomatic. Instead, this article shows that this notion was an unintentional by-product of the research conducted into the condition, the results of which opposed the somaticist philosophy that many of the researchers had tried to uphold.

  19. [Mental disorders in German soldiers after deployment - impact of personal values and resilience].

    Zimmermann, Peter; Firnkes, Susanne; Kowalski, Jens; Backus, Johannes; Alliger-Horn, Christina; Willmund, Gerd; Hellenthal, Andrea; Bauer, Amanda; Petermann, Franz; Maercker, Andreas


    Soldiers are at increased risk of developing mental health disorders after military deployment. The impact of personal values on psychological symptomatology based on an empirical working model has not yet been studied in a military environment. 117 German Armed Forces soldiers completed the Portrait-Values-Questionnaire (PVQ), the Patient-Health-Questionnaire (PHQ) and the Resilience-Scale (RS-11) after their deployment to Afghanistan. In the regression analyses the values hedonism, benevolence, tradition, self-direction and universalism had a differential significant impact on depression, anxiety and somatoform symptoms of the PHQ. The RS-11 sum scale values were negatively correlated with symptomatology. Personal values and resilience seem to be associated with psychological symptomatology in soldiers after military deployment. The results can contribute to the further development of both preventive and therapeutic approaches. © Georg Thieme Verlag KG Stuttgart · New York.

  2. Characteristics of soldiers with self-harm in the israeli defense forces.

    Shelef, Leah; Fruchter, Eyal; Spiegel, Dror Ortasse; Shoval, Gal; Mann, J John; Zalsman, Gil


    Suicide is the leading cause of soldier death in the Israeli Defense Forces (IDF) in peace time. Suicide attempt (SA) and non-suicidal self-injury (NSSI) are risk factors for death by suicide in civilian studies and therefore their predictive value needs to be determined in the military. All army screening, psychometric and demographic data on consecutive cases of IDF soldier self-harm during the years 2010-2011 were analyzed. The Columbia Suicide Severity Rating Scale was used retrospectively to classify self-harm as suicidal or NSSI. The Suicide Ideation Scale and the Suicide Intent Scale were scored retrospectively by trained clinical psychologists. A total of 107 soldiers reported self-harm during the study period, comprising 70 SA and 37 with NSSI. The most prevalent diagnosis was personality disorder (n = 48). Soldiers with any mood/anxiety disorders comprised the smallest group (n = 21) and included major depression, dysthymia, anxiety, and posttraumatic stress disorder. Soldiers with NSSI (n = 37) did not differ in any of the characteristics from those who attempted suicide (n = 70). Unlike the well-known female dominance in both SA and NSSI patients in other settings, males dominated this army sample in both groups. Soldiers with self-harm (both SA and NSSI) cannot be easily distinguished by any demographics or specific psychological attributes detectable at induction, and the scales used in suicide research cannot predict an attempt or NSSI. Unlike civilian samples, males dominated attempter and NSSI groups and the reason for this may be multifactorial. These retrospective findings, if replicated, indicate the need for different screening strategies at induction into the military.

  3. Meralgia paresthetica due to body armor wear in U.S. soldiers serving in Iraq: a case report and review of the literature.

    Fargo, Matthew V; Konitzer, Lisa N


    Meralgia paresthetica is a disorder of the lateral femoral cutaneous nerve that results in symptoms of anterolateral thigh paresthesias and dysesthesias without associated loss of reflexes or motor weakness. Chronic meralgia paresthetica, not related to traumatic or lesion-producing compression of the nerve, is associated with obesity, pregnancy, tight-fitting garments, as well as specific duty uniform belts used by police officers and carpenters. Cases are presented in which two U.S. soldiers in Iraq experienced symptoms of meralgia paresthetica, most likely due to repetitive wear of protective body armor. Although use of protective body armor is proven to be lifesaving, modifications to improve current equipment may help to decrease morbidities such as meralgia paresthetica.

  4. Relationship between serum and csf glucose in subarachnoid ‎hemorrhage

    ayantani Ghosh


    Full Text Available Introduction: There has been considerable controversy regarding the effect of serum and ‎cerebrospinal fluid (csf glucose levels in the prognosis of aneurysmal subarachnoid hemorrhage ‎‎(aSAH patients.‎Objective: We have explored the relationship between serum and csf glucose serum glucose ‎levels in such patients and have also explored the levels of serum and csf glucose required to ‎maintain a good outcome.‎Methods: Retrospective review of 2000 aSAH patients, from a prospectively collected database ‎of Thomas Jefferson University Hospital, was done. The Hunt-Hess (H-H grade of the SAH, ‎cerebral and serum glucose on admission, serum glucose on the day of surgery and 14 days post ‎the surgery as well as the GOS-E score at discharge was noted. Parameters were analyzed ‎individually for significance via contingency tables and significant parameters (p < 0.05 were ‎further examined. Relationship between serum and csf glucose is established via Spearman's rank ‎correlation coefficient.‎Result: Correlation between csf and serum glucose at admission was found to be 0.52, it ‎increased from HH grade 1-4 and then became negative but more tightly bound at HH5. Serum ‎glucose higher than 151.58 mg/dl (95% confidence interval, 141.36- 160.63 and csf glucose ‎higher than 77.83 mg/dl (95% confidence interval, 75.05- 80.61 was found to be associated with ‎worse outcome. 95.57% of the patients, who had even a single event of hypoglycemia, have had ‎a previous episode of hyperglycemia and fared badly. Csf glucose < 38 mg/dl also led to more ‎deaths.‎Conclusion: Serum and csf glucose bear a linear relationship in mild to moderate SAH. ‎Incidences of hypoglycemia in aSAH patients are mainly due to the intensive insulin therapy to ‎combat a hyperglycemic episode and results in worse outcome. Hence, serum glucose level of 80-‎‎140 mg/dl and csf glucose level of 38-75 mg/dl should be maintained in all aSAH patients.‎

  5. Cloning and expression of feline colony stimulating factor receptor (CSF-1R) and analysis of the species specificity of stimulation by colony stimulating factor-1 (CSF-1) and interleukin-34 (IL-34)

    Gow, Deborah J.; Garceau, Valerie; Pridans, Clare; Gow, Adam G.; Simpson, Kerry E.; Gunn-Moore, Danielle; Hume, David A.


    Colony stimulating factor (CSF-1) and its receptor, CSF-1R, have been previously well studied in humans and rodents to dissect the role they play in development of cells of the mononuclear phagocyte system. A second ligand for the CSF-1R, IL-34 has been described in several species. In this study, we have cloned and expressed the feline CSF-1R and examined the responsiveness to CSF-1 and IL-34 from a range of species. The results indicate that pig and human CSF-1 and human IL-34 are equally effective in cats, where both mouse CSF-1 and IL-34 are significantly less active. Recombinant human CSF-1 can be used to generate populations of feline bone marrow and monocyte derived macrophages that can be used to further dissect macrophage-specific gene expression in this species, and to compare it to data derived from mouse, human and pig.

    Abdulle, Sahra; Mellgren, Asa; Brew, Bruce J; Cinque, Paola; Hagberg, Lars; Price, Richard W; Rosengren, Lars; Gisslén, Magnus


    The light subunit of the neurofilament protein (NFL), a major structural component of myelinated axons, is a sensitive indicator of axonal injury in the central nervous system (CNS) in a variety of neurodegenerative disorders. Cerebrospinal fluid (CSF) NFL concentrations were measured by ELISA (normal NFL concentrations were significantly higher in patients with ADC (median 2590 ng/l, IQR 780-7360) and CNS OIs (2315 ng/l, 985-7390 ng/l) than in neuroasymptomatic patients (NFL declined during HAART to the limit of detection in parallel with virological response and neurological improvement in ADC.CSF NFL concentrations were higher in neuroasymptomatic patients with lower CD4-cell strata than higher, p or =200/microl. The findings of this study support the value of CSF NFL as a useful marker of ongoing CNS damage in HIV infection. Markedly elevated CSF NFL concentrations in patients without CNS OIs are associated with ADC, follow the grade of severity, and decrease after initiation of effective antiretroviral treatment. Nearly all previously suggested CSF markers of ADC relate to immune activation or HIV viral load that do not directly indicate brain injury. By contrast NFL is a sensitive marker of such injury, and should prove useful in evaluating the presence and activity of ongoing CNS injury in HIV infection.

    Merisson, Edyta; Mattsson, Niklas; Zetterberg, Henrik; Blennow, Kaj; Pikwer, Andreas; Mehmedagic, Irma; Acosta, Stefan; Åkeson, Jonas


    Repair of extensive aortic disease may be associated with spinal cord ischaemia (SCI). Here we test if levels of cerebrospinal fluid (CSF) biomarkers for neuronal injury are altered in patients with SCI after advanced endovascular repair in extensive aortic disease. CSF was sampled for up to 48 h in ten patients undergoing endovascular aortic repair and analyzed for the axonal damage markers total-tau (T-tau) and neurofilament light (NFL). Six of ten patients developed SCI (clinically present within 3-6 h). CSF levels of NFL increased up to 37-fold in patients with, but were stable in patients without, SCI. CSF levels of T-tau also increased in patients with SCI, but with some overlap with patients without SCI. Levels of NFL and T-tau did not increase until after the appearance of clinical signs of neurological dysfunction (12-48 h after aortic repair). The CSF biomarkers NFL and T-tau both reflect development of SCI after endovascular aortic repair, but do not rise until after clinical signs of SCI appear. Future studies are desirable to further evaluate potential use of these biomarkers for assessment of the severity of SCI, and also to identify earlier biomarkers of SCI. Copyright © 2015.

    Podlesniy, Petar; Vilas, Dolores; Taylor, Peggy; Shaw, Leslie M; Tolosa, Eduard; Trullas, Ramon


    Mitochondrial DNA regulates mitochondrial function which is altered in both idiopathic and familial forms of Parkinson's disease. To investigate whether these two disease forms exhibit an altered regulation of mitochondrial DNA we measured cell free mitochondrial DNA content in cerebrospinal fluid (CSF) from idiopathic and LRRK2-related Parkinson's disease patients. The concentration of mitochondrial DNA was measured using a digital droplet polymerase chain reaction technique in a total of 98 CSF samples from a cohort of subjects including: 20 LRRK2(G2019S) mutation carriers with Parkinson's disease, 26 asymptomatic LRRK2(G2019S) mutation carriers, 31 patients with idiopathic Parkinson's disease and 21 first-degree relatives of LRRK2 Parkinson's disease patients without the mutation. Here we report that LRRK2(G2019S) mutation carriers with Parkinson's disease exhibit a high concentration of mitochondrial DNA in CSF compared with asymptomatic LRRK2(G2019S) mutation carriers and with idiopathic Parkinson's disease patients. In addition, idiopathic, but not LRRK2 Parkinson's disease is associated with low CSF concentration of α-synuclein. These results show that high mitochondrial DNA content in CSF distinguishes idiopathic from LRRK2-related Parkinson's disease suggesting that different biochemical pathways underlie neurodegeneration in these two disorders.

    Full Text Available Objective(s: Granulocyte-colony stimulating factor (G-CSF is used in clinical practice for the treatment of neutropenia and to stimulate generation of hematopoietic stem cells in bone marrow donors. In the present study, the ability of G-CSF in mobilizing exogenous bone marrow stem cells (BMSCs from peripheral blood into the brain was tested. We for the first time injected a small amount of BMSCs through the tail vein. Materials and Methods: We choose 25 male Wistar rats (200–250 g were lesioned by 6-OHDA injected into the left substantia nigra, pars compacta (SNpc. G-CSF (70 µg/kg/day was given from the 7th day after lesion for five days. The BMSCs (2×105 were injected through the dorsal tail vein on the 7th day after lesion. Results:The number of rotations was significantly lower in the stem cell therapy group than in the control group. In the third test in the received G-CSF and G-CSF+stem cells groups, animals displayed significant behavioral recovery compared with the control group (P

  10. Benign spinal meningioma without dural attachment presenting delayed CSF dissemination and malignant transformation.

    Tsuda, Kyoji; Akutsu, Hiroyoshi; Yamamoto, Tetsuya; Ishikawa, Eiichi; Saito, Atsushi; Nakai, Kei; Takano, Shingo; Matsumura, Akira


    Benign spinal meningiomas have good prognoses, with low rates of recurrence and no cerebrospinal fluid (CSF) dissemination. However, we experienced an extremely rare case of initially benign non-dura-based spinal meningioma that showed multiple CSF disseminated lesions, which progressed for 14 years. A 29-year-old woman without neurofibromatosis presented with progressing dysesthesia in her lower limbs, low back pain, and intermittent claudication. Magnetic resonance imaging (MRI) showed an intradural extramedullary mass lesion at the Th10/11 level. The patient underwent a tumor resection. Intraoperative findings indicated that the tumor had no dural attachment. Histopathological diagnosis after gross total removal was microcystic meningioma (grade I, WHO 2007). Seven years after the first operation, other lesions appeared at the levels of Th11/12, L1, and L2/3 in MRI. These tumors were slow growing and became symptomatic; thus, a second surgery was performed 14 years after the first operation. The histopathological diagnosis was atypical meningioma (grade II, WHO 2007). Benign spinal meningiomas show CSF dissemination extremely rarely, although some authors have reported non-dura-based intraspinal clear-cell meningiomas showing CSF dissemination. However, even in cases of WHO grade I, neurosurgeons should pay attention to late CSF dissemination and malignant transformation after surgical removal of non-dura-based intraspinal meningiomas.

  11. Antibody-free quantification of seven tau peptides in human CSF using targeted mass spectrometry

    Pauline eBros


    Full Text Available Tau protein concentration in cerebrospinal fluid (CSF is currently used as a sensitive and specific biomarker for Alzheimer's disease. Its detection currently relies on ELISA but the perspective of using mass spectrometry (MS to detect its different proteoforms represents an interesting alternative. This is however an analytical challenge because of its low concentration in the CSF, a biological fluid collected in small volume by lumbar puncture, and with a high structural heterogeneity. To overcome these issues, instead of using immunocapture as previously done, we rather relied on an original two steps pre-fractionation technique of CSF: perchloric acid followed by micro solid phase extraction (µSPE. We could then measure seven tau trypsic peptides by Multiple Reaction Monitoring (MRM on a triple quadrupole mass spectrometer. Quantification was performed using isotopically labelled 15N- recombinant Tau protein as internal standard and validated using CSF pools with low, medium or high tau concentrations. Repeatability, intermediate precision, linearity, limit of quantification and recovery were calculated for the different peptides. This new MRM assay, which allowed for the first time CSF tau protein quantification without immunocapture, has important potential application to follow tau metabolism in both diagnostic and therapeutic research.

We could then measure seven tau trypsic peptides by Multiple Reaction Monitoring (MRM) on a triple quadrupole mass spectrometer. Quantification was performed using isotopically labeled (15)N- recombinant tau protein as internal standard and validated using CSF pools with low, medium, or high tau concentrations (HTCs). Repeatability, intermediate precision, linearity, limit of quantification (LOQ), and recovery were calculated for the different peptides. This new MRM assay, which allowed for the first time CSF tau protein quantification without immunocapture, has important potential application to follow tau metabolism in both diagnostic and therapeutic research.

  13. NIA-AA staging of preclinical Alzheimer disease: discordance and concordance of CSF and imaging biomarkers.

    Vos, Stephanie J B; Gordon, Brian A; Su, Yi; Visser, Pieter Jelle; Holtzman, David M; Morris, John C; Fagan, Anne M; Benzinger, Tammie L S


    The National Institute of Aging and Alzheimer's Association (NIA-AA) criteria for Alzheimer disease (AD) treat neuroimaging and cerebrospinal fluid (CSF) markers of AD pathology as if they would be interchangeable. We tested this assumption in 212 cognitively normal participants who have both neuroimaging and CSF measures of β-amyloid (CSF Aβ1-42 and positron emission tomography imaging with Pittsburgh Compound B) and neuronal injury (CSF t-tau and p-tau and structural magnetic resonance imaging) with longitudinal clinical follow-up. Participants were classified in preclinical AD stage 1 (β-amyloidosis) or preclinical AD stage 2+ (β-amyloidosis and neuronal injury) using the NIA-AA criteria, or in the normal or suspected non-Alzheimer disease pathophysiology group (neuronal injury without β-amyloidosis). At baseline, 21% of participants had preclinical AD based on CSF and 28% based on neuroimaging. Between modalities, staging was concordant in only 47% of participants. Disagreement resulted from low concordance between biomarkers of neuronal injury. Still, individuals in stage 2+ using either criterion had an increased risk for clinical decline. This highlights the heterogeneity of the definition of neuronal injury and has important implications for clinical trials using biomarkers for enrollment or as surrogate end point measures.

  14. Engagement of PSGL-1 upregulates CSF-1 transcription via a mechanism that may involve Syk.

    Ba, Xue-Qing; Chen, Cui-Xia; Xu, Ting; Cui, Ling-Ling; Gao, Yan-Guang; Zeng, Xian-Lu


    PSGL-1, the optimal selectin ligand demonstrated by in vivo studies to date, is an essential adhesive molecule mediating the rolling of leukocytes on the endothelial cells and the recruitment of leukocytes to the inflamed tissue. Recent studies demonstrated, in addition to its direct role in capture of leukocytes from the bloodstream, PSGL-1 also functions as a signal-transducing receptor and initiates a series of intracellular signal events during the activation of leukocytes. Our present work showed antibody engagement of PSGL-1 upregulated the transcriptional activity of CSF-1 promotor and increased the endogenous expression of CSF-1 mRNA in Jurkat cell. Overexpression of wild-typed non-receptor tyrosine kinase Syk, but not kinase dead mutant of Syk, promoted the upregulation of the transcriptional activity of CSF-1 promoter caused by antibody engagement of PSGL-1. Additionally, special inhibitor of Syk Piceatannol suppressed the increase of CSF-1 mRNA caused by the engagement of PSGL-1. The results suggest that signal transducted by PSGL-1 upregulate the transcriptional activity of CSF-1, and non-receptor tyrosine kinase Syk participates in this pathway.

  15. Phase I dose intensification study of 2-weekly epirubicin with GM-CSF in advanced cancer.

    Michael, M; Toner, G C; Olver, I N; Fenessy, A; Bishop, J F


    This study investigated dose intensification of epirubicin administered as a 2-weekly regimen with granulocyte-macrophage colony-stimulating factor (GM-CSF) support. The aim was to define the maximally tolerated dose of epirubicin and to assess the efficacy of GM-CSF to ameliorate its toxicity. Patients with anthracycline-responsive advanced malignancies were eligible. Six dose levels, commencing at 90 mg/m2, of epirubicin administered every 2 weeks for four courses were planned with GM-CSF 10 micrograms/kg/day administered for 10 days from the second day of each course. Six patients were to be entered at each dose level, and escalation to the next level was based upon toxicity criteria. Twelve patients were entered, six at dose level 1 (90 mg/m2) and six at dose level 2 (120 mg/m2). Prospectively defined haematological dose-limiting toxicities were noted in one patient at dose level 1 and in five patients at dose level 2. Further dose escalation was not attempted. Significant nonhaematological toxicities included febrile neutropenia in two and four patients at dose levels 1 and 2, respectively. This study has demonstrated that epirubicin can be safely administered at 2 week intervals with GM-CSF at a dose of 90 mg/m2, equivalent to the previously reported maximum tolerated dose intensity of 45 mg/m2/week. Neutropenia was dose-limiting despite the use of GM-CSF.

  16. Effects of recombinant human GM-CSF on proliferation of clonogenic cells in acute myeloblastic leukemia.

    Griffin, J D; Young, D; Herrmann, F; Wiper, D; Wagner, K; Sabbath, K D


    Proliferation of acute myeloblastic leukemia (AML) cells in vitro is limited in most cases to a small subset of blasts that have several properties of stem cells. These leukemic colony-forming cells (AML-CFU) generally require addition of exogenous growth factors for proliferation in agar or methylcellulose. These factors can be supplied by media conditioned by phytohemagglutinin-stimulated normal leukocytes or by CSF-secreting tumor cell lines. However, the exact factor or factors required for stimulation of AML-CFU growth have not been defined. We compared the AML-CFU stimulatory activity of a human recombinant GM-CSF with that of GCT-CM, Mo-CM, and the PHA-leukocyte feeder system in 15 cases of AML. In each of the 12 cases that required exogenous growth factors for maximum AML-CFU growth, recombinant GM-CSF could replace either GM-CSF or Mo-CM, and could partially replace the PHA-leukocyte feeder system. These results indicate that this GM-CSF is a growth promoter of AML-CFU in these culture systems.

  17. Detection of virus in CSF from the cases with meningoencephalitis by next-generation sequencing.

    We screened for viral DNA in cerebrospinal fluid samples using next-generation sequencing (NGS) technology to diagnose CNS viral infections. We collected CSF samples from four cases with clinically suspected viral meningoencephalitis. DNA extracted from the samples was analyzed with NGS, and the results were further validated using PCR. Herpes simplex virus 1 (HSV-1) was detected in the CSF of two patients, HSV-2 and human herpes virus type 3 (HHV-3, VZV) in the CSF of two other patients separately. The number of unique reads of the identified viral genes ranged from 144 to 44205 (93.51 to 99.57%). The coverage of identified viral genes ranged from 12 to 98% with a depth value of 1.1 to 35, respectively. The results were further confirmed using PCR in three cases. The clinical presentation and outcomes of these four cases were consistent with the diagnostic results of NGS. NGS of CSF samples can be used as a diagnostic assay for CNS viral infection. Its further application for "pan-viral" or even "pan-microbial" screening of CSF might influence the diagnosis of CNS infectious diseases.

    CSF lactate measurement is recommended when nosocomial meningitis is suspected, but its value in community-acquired bacterial meningitis is controversial. We evaluated the diagnostic performance of lactate and other CSF parameters in a prospective cohort of adult patients with acute meningitis. Diagnostic accuracy of lactate and other CSF parameters in patients with microbiologically documented episodes was assessed by receiver operating characteristic (ROC) curves. The cut-offs with the best diagnostic performance were determined. Forty-five of 61 patients (74%) had a documented bacterial (n = 18; S. pneumoniae, 11; N. meningitidis, 5; other, 2) or viral (n = 27 enterovirus, 21; VZV, 3; other, 3) etiology. CSF parameters were significantly different in bacterial vs. viral meningitis, respectively (p viral meningitis, with a cutoff set at 3.5 mmol/l providing 100% sensitivity, specificity, PPV, NPV, and efficiency. CSF lactate had the best accuracy for discriminating bacterial from viral meningitis and should be included in the initial diagnostic workup of this condition.

  19. Sphingomyelin as a myelin biomarker in CSF of acquired demyelinating neuropathies.

    Fast, accurate and reliable methods to quantify the amount of myelin still lack, both in humans and experimental models. The overall objective of the present study was to demonstrate that sphingomyelin (SM) in the cerebrospinal fluid (CSF) of patients affected by demyelinating neuropathies is a myelin biomarker. We found that SM levels mirror both peripheral myelination during development and small myelin rearrangements in experimental models. As in acquired demyelinating peripheral neuropathies myelin breakdown occurs, SM amount in the CSF of these patients might detect the myelin loss. Indeed, quantification of SM in 262 neurological patients showed a significant increase in patients with peripheral demyelination (p = 3.81 * 10 - 8) compared to subjects affected by non-demyelinating disorders. Interestingly, SM alone was able to distinguish demyelinating from axonal neuropathies and differs from the principal CSF indexes, confirming the novelty of this potential CSF index. In conclusion, SM is a specific and sensitive biomarker to monitor myelin pathology in the CSF of peripheral neuropathies. Most importantly, SM assay is simple, fast, inexpensive, and promising to be used in clinical practice and drug development.

  20. Regulation of cerebrospinal fluid (CSF) flow in neurodegenerative, neurovascular and neuroinflammatory disease.

    Simon, Matthew J; Iliff, Jeffrey J


    Cerebrospinal fluid (CSF) circulation and turnover provides a sink for the elimination of solutes from the brain interstitium, serving an important homeostatic role for the function of the central nervous system. Disruption of normal CSF circulation and turnover is believed to contribute to the development of many diseases, including neurodegenerative conditions such as Alzheimer's disease, ischemic and traumatic brain injury, and neuroinflammatory conditions such as multiple sclerosis. Recent insights into CSF biology suggesting that CSF and interstitial fluid exchange along a brain-wide network of perivascular spaces termed the 'glymphatic' system suggest that CSF circulation may interact intimately with glial and vascular function to regulate basic aspects of brain function. Dysfunction within this glial vascular network, which is a feature of the aging and injured brain, is a potentially critical link between brain injury, neuroinflammation and the development of chronic neurodegeneration. Ongoing research within this field may provide a powerful new framework for understanding the common links between neurodegenerative, neurovascular and neuroinflammatory disease, in addition to providing potentially novel therapeutic targets for these conditions. This article is part of a Special Issue entitled: Neuro Inflammation edited by Helga E. de Vries and Markus Schwaninger.

    The aim of this study was to examine cross-sectionally whether higher cardiorespiratory fitness (CRF) might favorably modify amyloid-β (Aβ)-related decrements in cognition in a cohort of late-middle-aged adults at risk for Alzheimer's disease (AD). Sixty-nine enrollees in the Wisconsin Registry for Alzheimer's Prevention participated in this study. They completed a comprehensive neuropsychological exam, underwent 11C Pittsburgh Compound B (PiB)-PET imaging, and performed a graded treadmill exercise test to volitional exhaustion. Peak oxygen consumption (VO2peak) during the exercise test was used as the index of CRF. Forty-five participants also underwent lumbar puncture for collection of cerebrospinal fluid (CSF) samples, from which Aβ42 was immunoassayed. Covariate-adjusted regression analyses were used to test whether the association between Aβ and cognition was modified by CRF. There were significant VO2peak*PiB-PET interactions for Immediate Memory (p=.041) and Verbal Learning & Memory (p=.025). There were also significant VO2peak*CSF Aβ42 interactions for Immediate Memory (p<.001) and Verbal Learning & Memory (p<.001). Specifically, in the context of high Aβ burden, that is, increased PiB-PET binding or reduced CSF Aβ42, individuals with higher CRF exhibited significantly better cognition compared with individuals with lower CRF. In a late-middle-aged, at-risk cohort, higher CRF is associated with a diminution of Aβ-related effects on cognition. These findings suggest that exercise might play an important role in the prevention of AD.

    Full Text Available Objective. To evaluate the therapeutic effects of G-CSF administration after intraosseous (IO resuscitation in hemorrhagic shock (HS combined with cutaneous injury rats. Methods. The rats were randomly divided into four groups: (1 HS with resuscitation (blank, (2 HS with resuscitation + G-CSF (G-CSF, 200 μg/kg body weight, subcutaneous injection, (3 HS with resuscitation + normal saline solution injection (normal saline, and (4 HS + G-CSF injection without resuscitation (Unres/G-CSF. To estimate the treatment effects, the vital signs of alteration were first evaluated, and then wound closure rates and homing of MSCs and EPCs to the wound skins and vasculogenesis were measured. Besides, inflammation and vasculogenesis related mRNA expressions were also examined. Results. IO infusion hypertonic hydroxyethyl starch (HHES exhibited beneficial volume expansion roles and G-CSF administration accelerated wound healing 3 days ahead of other groups under hemorrhagic shock. Circulating and the homing of MSCs and EPCs at wound skins were significantly elevated at 6 h after G-CSF treatment. Inflammation was declined since 3 d while angiogenesis was more obvious in G-CSF treated group on day 9. Conclusions. These results suggested that the synergistical application of HHES and G-CSF has life-saving effects and is beneficial for improving wound healing in HS combined with cutaneous injury rats.

    Objective To explore the effect of the interaction between microphage colony-stimulating factor (M-CSF) and minichromosome maintenance protein-7(Mcm7) on DNA replication in HeLa cells. Methods pCMV/nuc/mye, pCMV/nuc/GFP and pCMV/nuc/M-CSF vector were stably transfected into HeLa cells by Lipofectarnine, respectively. After screening with G418, the expression and localization of M-CSF in HeLa cells were verified by RT-PCR, Western blot and immunofluoreseence staining. The statue and interaction between intracellular M-CSF and Mcm7 in HeLa cells was analyzed by co-immunoprecipitation. The effect of the interaction between M-CSF and Mcm7 on DNA replication was analyzed by a mammalian cell or cell-free DNA replication system in vitro. Results The results indicated that the M-CSF-transfected HeLa cells stably express both M-CSF mRNA and protein, and that M-CSF protein is located to the nuclei of HeLa cells mentioned above. To further analyze the status and interaction between intracellular M-CSF and Mcm7, the Mcm7 from HeLa cells was precipitated with anti-Mcm7 antibody and followed by Protein A/G PLUS agarose. The precipitation was blotted with anti-M-CSF monoclonal antibody. The results show that M-CSF was coprecipitated with Mcm7, so intracellular M-CSF existed in Mcm7-bound state. The DNA replication experiments reveal that a higher percentage of the replicating nuclei is present either in unsyn-chronized or in both synchronized G1 and S phase M-CSF-transfected HeLa cells, compared with both pCMV/nuc-transfeeted and un-transfected HeLa cells, which suggests that interaction between M-CSF and Mcm7 promote both the initiation and elongation of DNA replication. Conclusions M-CSF directly interacts with McmT. The interaction between M-CSF and Mcm7 promotes both the initiation and elongation of DNA replication.

  14. GM-CSF Controls Nonlymphoid Tissue Dendritic Cell Homeostasis but Is Dispensable for the Differentiation of Inflammatory Dendritic Cells

    GM-CSF (Csf-2) is a critical cytokine for the in vitro generation of dendritic cells (DCs) and is thought to control the development of inflammatory DCs and resident CD103(+) DCs in some tissues. Here we showed that in contrast to the current understanding, Csf-2 receptor acts in the steady state to promote the survival and homeostasis of nonlymphoid tissue-resident CD103(+) and CD11b(+) DCs. Absence of Csf-2 receptor on lung DCs abrogated the induction of CD8(+) T cell immunity after immuniz...

  15. A surgical method to improve the homeostasis of CSF for the treatment of Alzheimer’s disease

    Yang Qin


    Full Text Available Reduced cerebrospinal fluid (CSF production and increased resistance to CSF outflow are considered to be associated with aging, and are also characteristics of Alzheimer disease (AD. These changes probably result in a decrease in the efficiency of the mechanism by which CSF removes toxic molecules such as amyloid-β (Aβ and tau from the interstitial fluid space. Soluble Aβ is potently neurotoxic and dysfunction in CSF circulation can accelerate the progression of AD. Current therapies for AD exhibit poor efficiency; therefore, a surgical method to improve the homeostasis of CSF is worthy of investigation. To achieve this, we conceived a novel device, which consists of a ventriculo-peritoneal shunt, an injection port and a portable infusion pump. Artificial CSF is pumped into the ventricles and the artificial CSF composition, infusion modes and pressure threshold of shunting can be adjusted according to the intracranial pressure and CSF contents. We hypothesize that this active treatment for CSF circulation dysfunction will significantly retard the progression of AD.

    An early and accurate in vivo diagnosis of rapidly progressive dementia remains challenging, despite its critical importance for the outcome of treatable forms, and the formulation of prognosis. Real-Time Quaking-Induced Conversion (RT-QuIC) is an in vitro assay that, for the first time, specifically discriminates patients with prion disease. Here, using cerebrospinal fluid (CSF) samples from 239 patients with definite or probable prion disease and 100 patients with a definite alternative diagnosis, we compared the performance of the first (PQ-CSF) and second generation (IQ-CSF) RT-QuIC assays, and investigated the diagnostic value of IQ-CSF across the broad spectrum of human prions. Our results confirm the high sensitivity of IQ-CSF for detecting human prions with a sub-optimal sensitivity for the sporadic CJD subtypes MM2C and MM2T, and a low sensitivity limited to variant CJD, Gerstmann-Sträussler-Scheinker syndrome and fatal familial insomnia. While we found no difference in specificity between PQ-CSF and IQ-CSF, the latter showed a significant improvement in sensitivity, allowing prion detection in about 80% of PQ-CSF negative CJD samples. Our results strongly support the implementation of IQ-CSF in clinical practice. By rapidly confirming or excluding CJD with high accuracy the assay is expected to improve the outcome for patients and their enrollment in therapeutic trials.

  17. Extensive fitness and human cooperation.

    van Hateren, J H


    Evolution depends on the fitness of organisms, the expected rate of reproducing. Directly getting offspring is the most basic form of fitness, but fitness can also be increased indirectly by helping genetically related individuals (such as kin) to increase their fitness. The combined effect is known as inclusive fitness. Here it is argued that a further elaboration of fitness has evolved, particularly in humans. It is called extensive fitness and it incorporates producing organisms that are merely similar in phenotype. The evolvability of this mechanism is illustrated by computations on a simple model combining heredity and behaviour. Phenotypes are driven into the direction of high fitness through a mechanism that involves an internal estimate of fitness, implicitly made within the organism itself. This mechanism has recently been conjectured to be responsible for producing agency and goals. In the model, inclusive and extensive fitness are both implemented by letting fitness increase nonlinearly with the size of subpopulations of similar heredity (for the indirect part of inclusive fitness) and of similar phenotype (for the phenotypic part of extensive fitness). Populations implementing extensive fitness outcompete populations implementing mere inclusive fitness. This occurs because groups with similar phenotype tend to be larger than groups with similar heredity, and fitness increases more when groups are larger. Extensive fitness has two components, a direct component where individuals compete in inducing others to become like them and an indirect component where individuals cooperate and help others who are already similar to them.

    Zinc is crucial for brain development and psychiatric regulation. In the present study, we investigated the relationship between cerebrospinal fluid (CSF) zinc level and anxiety in a group of male Chinese subjects. Results demonstrated that zinc levels had no considerable interindividual variations, ranging from 8.37 to 16.83µm. Correlation analyses revealed that CSF Zinc levels were positively correlated with education years (r=0.225, p=0.024) and negatively correlated with SAS scores (r=-0.287, p=0.004), but not associated with age or BMI. In conclusion, this present study suggests that CSF zinc level is associated with anxiety. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  19. Association between cortical thickness and CSF biomarkers in mild cognitive impairment and Alzheimer’s disease

    Mohades, Sara; Dubois, Jonathan; Parent, Maxime;

    between cortical thinning, amyloidosis or tau hyperphosphorylation depends on cortical regions and clinical stages of AD. Methods: T1-weighed MRIs and associated CSF markers from individuals with mild cognitive impairment (MCI; 16), Alzheimer Disease (AD; n¼7) and age-matched cognitively normal subjects...... regional cortical thinning (CT) measured by Magnetic Resonance Imaging (MRI) and brain amyloidosis (measured by CSF Ab 1-42 concentrations), or tau hyperphosphorylation (tau 181; p-tau) in Alzheimer’s Disease (AD) and Mild Cognitive Impairment (MCI) patients. We test the hypothesis that the association...... (CN; n¼8) were obtained from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohort. Cortical surface reconstruction and group registration were generated using Freesurfer. A general linear model was used to conduct regressions between CSF markers and cortical thickness. Results: Correlation...

  20. Interpretation and value of MR CSF flow studies for paediatric neurosurgery

    Samukelisiwe Sithembile Mbonane


    Full Text Available Imaging techniques may be underutilised when clinicians are unaware of the technique or do not recognise its potential. Phase-contrast MR imaging (PC-MRI is a rapid, simple and non-invasive technique that is sensitive to CSF flow. It demonstrates a mechanical coupling between cerebral blood and CSF flow throughout the cardiac cycle. Neurosurgeons should be able to request this procedure routinely as part of an MRI request. This paper gives an overview of the indications, technical requirements, technique and interpretation, using image examples. Indications for CSF flow studies include assessment and functionality of shunt treatment in patients with hydrocephalus; hydrocephalus associated with achondroplasia; Chiari I malformation; confirmation of aqueductal stenosis; and determining patency of a third ventriculostomy.
