  15. The ABM Treaty

    SciTech Connect

    Stutzle, W.; Jasani, B.; Cowen, R.

    1987-01-01

    The foremost challenge of this age and the next is to harness our political resources to prevent the East-West relationship from turning into a conflict. Among the measures employed to stabilize the strategic relationship, the 1972 Anti-Ballistic Missile (ABM) Treaty is of profound importance. It codifies the central principle of the nuclear age: a co-operative approach in limiting offensive and defensive strategic forces. This principle has been challenged-both by failures in East and West to resist the allure of technology and by a more general errosion of political will to tackle together the problems of the nuclear offence-defence relationship. This paper makes a contribution to the debate over the strategic relationship, in particular the role of the ABM Treaty. It is first in a series of Strategic Issue Papers (SIP) that address topical issues of international peace and security. In order to contribute to a better understanding of the problems involved and to stimulate debate, SIPRI has produced this book before the commencement of the third ABM Treaty Review Conference.

  16. Alien Abductions

    NASA Astrophysics Data System (ADS)

    Nickell, Joe

    2000-03-01

    Since the beginning of the modern UFO craze in 1947, an elaborate mythology has developed concerning alleged extraterrestrial visitations. ``Flying saucer" sightings (typically involving misperceptions of such mundane phenomena as meteors and research balloons) began to be accompanied in the 1950s by reports from ``contactees," persons who claimed to have had close encounters with, even to have been transported to distant planets by, UFO occupants. By the 1960s came reports of sporadic ``abductions" which have proliferated in correlation with media interest. (Indeed, by interaction between claimants and media the portrayal of aliens has evolved from a multiplicity of types into the rather standardized big-eyed humanoid model.) While evidence of alien contact has often been faked--as by spurious photos, ``crop circles," and the notorious ``Alien Autopsy" film--few alien abduction reports appear to be hoaxes. Most seem instead to come from sincere, sane individuals. Nevertheless, not one has been authenticated, and serious investigation shows that such claims can be explained as sleep-related phenomena (notably ``waking dreams"), hypnotic confabulation, and other psychological factors. As is typical of other mythologies, the alien myth involves supernormal beings that may interact with humans, and it purports to explain the workings of the universe and humanity's place within it.

    Future arms control treaty verification regimes may use radiation imaging measurements to confirm and track nuclear warheads or other treaty accountable items (TAIs). This project leverages advanced inference methods developed for medical and adaptive imaging to improve task performance in arms control applications. Additionally, we seek a method to acquire and analyze imaging data of declared TAIs without creating an image of those objects or otherwise storing or revealing any classified information. Such a method would avoid the use of classified-information barriers (IB).

  4. Star Wars testing and the ABM treaty

    SciTech Connect

    Bunn, M.

    1988-04-01

    In the defense authorization act, Congress has limited testing of the Strategic Defense Initiative (SDI) to those tests described by the Defense Department as within the bounds of the traditional interpretation of the treaty through fiscal year 1988. For the moment, the administration cannot move to implement its broad interpretation of the ABM Treaty, which would allow unlimited testing of exotic-technology Star Wars systems. Unfortunately, this victory over the broad interpretation is threatened by the administration's twisting of the traditional view. By stretching ambiguities in the treaty's language, the Defense Department is attempting to justify tests that press far into grey areas. A strong case can be made that some of the tests currently planned are likely to violate a reasonable reading of the traditional interpretation of the treaty. Other planned tests, while complying with the letter of the treaty, are clear efforts to circumvent the agreement's intent, undermining the effectiveness of the treaty regime. If the US justifies such tests by making unverifiable distinctions and exploiting loopholes, we will have no grounds for complaint when the USSR does the same, and we will ultimately lose the security benefits provided by the ABM Treaty. To clarify the compliance issues raised by SDI's current plans, this analysis describes the major past and planned SDI tests that may affect the ABM Treaty Regime.

  5. The politics of arms control treaty ratification

    SciTech Connect

    Krepon, M. ); Caldwell, D. )

    1991-01-01

    This book presents a critical examination of executive-congressional relations and the domestic politics of arms control treaty ratification within the United States during the twentieth century. The staring point of this study is the hypothesis that the politics of treaty ratification can be as important as the negotiations leading up to agreements. Benefits to international peace and security sought in years of painstaking diplomatic effort can be lost without Senate consent, as was the case with the Treaty of Versailles and the second treaty arising from the Strategic Arms Limitation Talks (SALT II). The authors of the case studies were requested to present first a brief, historical introduction to the case indicating why the case was important, the background concerning the origins of the treaty, and the treaty's major provisions. The purpose of the introduction to the case was not to provide a complete picture of the negotiating record but to set the stage for a more in-depth discussion of the events that followed after the treaty was signed. The authors address five substantive areas: the international political context of the treaty, the domestic political context, the role of the president, executive-congressional relations, and public opinion and the role of interest groups. The questions and issues concerning each of these areas are briefly summarized.

  3. The ABM treaty and Western security

    SciTech Connect

    Durch, W.J.

    1987-01-01

    This book reveals how the debate over SDI and the ABM Treaty is not about hardware feasibility but about the future nuclear strategies of East and West, about how much cooperation they can risk and how much competition they can stand. The author examines the issues that drive it: the major threats to the ABM Treaty, ranging from Soviet radar deployments to the testing of weapons in space; the role of defense constraints in offensive arms reduction; the possible risk of an unconstrained arms race should ABM limits be eased or removed; and the conflict reports about Soviet arms control compliance practices. He assesses three paths for U.S. policy: away from the ABM Treaty toward nationwide missile defense; away from SDI toward strengthened ABM Treaty; or toward limited defense for strategic forces.

    1996-01-01

    Progressive loss of CD4+ T lymphocytes, accompanied by opportunistic infections characteristic of the acquired immune deficiency syndrome, ahs been reported in the absence of any known etiology. The pathogenesis of this syndrome, a subset of idiopathic CD4+ T lymphocytopenia (ICL), is uncertain. We report that CD4+ T cells from seven of eight ICL patients underwent accelerated programmed cell death, a process facilitated by T cell receptor cross-linking. Apoptosis was associated with enhanced expression of Fas and Fas ligand in unstimulated cell populations, and partially inhibited by soluble anti-Fas mAb. In addition, apoptosis was suppressed by aurintricarboxylic acid, an inhibitor of calcium-dependent endonucleases and proteases, in cells from four of seven patients, The in vivo significance of these findings was supported by three factors: the absence of accelerated apoptosis in persons with stable, physiologic CD4 lymphopenia without clinical immune deficiency; detection of serum antihistone H2B autoantibodies, one consequence of DNA fragmentation, in some patients; and its selectivity, with apoptosis limited to the CD4 population in some, and occurring among CD8+ T cells predominantly in those individuals with marked depletion of both CD4+ T lymphocytes linked to clinical immune suppression have evidence for accelerated T cell apoptosis in vitro that may be pathophysiologic and amenable to therapy with apoptosis inhibitors.

    1993-01-01

    Four patients are described who presented with a paroxysmal form of the alien hand syndrome. Two patients with damage to one frontomedial cortex had brief episodes of abnormal motor behaviour of the contralateral arm that featured groping, grasping, and apparently purposeful but perseverative movements, which both patients interpreted as alien or foreign. The other two patients, with posterior parietal damage, reported a paroxysmal feeling of unawareness of the location of the contralateral arm, lack of recognition of the arm as their own, purposeless movements, and personification of the arm. These cases represent a new form of the alien hand syndrome manifested by brief, paroxysmal episodes, which may be due to ictal mechanisms. Images PMID:8331355

    2012-04-01

    If alien civilizations do, or did, exist, their technology will impact their environment. Some consideration has been given to the detection of large-scale astro-engineering, such as Dyson spheres. However, a very advanced technology might leave more subtle footprints requiring sophisticated scientific methods to uncover. We must not overlook the possibility that alien technology has impacted our immediate astronomical environment, even Earth itself, but probably a very long time ago. This raises the question of what traces, if anything, might remain today. I shall consider the possibilities of biological, geological and physical traces, and suggest ways that we might search for them.

  16. Forgetting and remembering alienation theory.

    PubMed

    Yuill, Chris

    2011-01-01

    Alienation theory has acted as the stimulus for a great deal of research and writing in the history of sociology. It has formed the basis of many sociological "classics" focused on the workplace and the experiences of workers, and has also been mobilized to chart wider social malaise and individual troubles. Alienation theory usage has, however, declined significantly since its heyday of the 1960s and 1970s. Here, the reasons why alienation theory was "forgotten" and what can be gained by "remembering" alienation theory are explored. to realize this ambition this article proceeds by (1) briefly visiting differing definitions of alienation theory, before charting its high point, and the various debates and tensions of the time, during the 1960s and 1970s; (2) analysing the reasons why alienation theory fell from grace from the 1980s onwards; (3) elaborating how and why alienation theory is still relevant for sociology and the wider social sciences today.

    It was the unequivocal intent on the part of both Indians and whites at the treaty-signing that the reservations were to be residential bases from which the Indians were to continue to utilize the total environment, including specifically all of their fishing locations, in order to maintain themselves.

    The INF and START Treaties form the basis for constraints on nuclear weapons. Their verification provisions are one of the great success stories of modern arms control and will be an important part of the foundation upon which the verification regime for further constraints on nuclear weapons will be constructed.

  19. The Nuclear Nonproliferation Treaty in Context

    NASA Astrophysics Data System (ADS)

    Davenport, Kelsey

    2017-01-01

    The 1968 Nuclear Nonproliferation Treaty (NPT) is the cornerstone of multilateral efforts to prevent the spread of nuclear weapons and promote efforts toward complete disarmament. In the grand bargain of the NPT, states foreswore pursuit of nuclear weapons in exchange for access to nuclear technology and limited nuclear arsenals to the five states (China, France, Russia, the United Kingdom and the United States) that tested such weapons before the NPT's conception. Now in its seventh decade, the NPT regime is embraced by the vast majority of the world's nations and is viewed as a critical element of international security. However, despite past successes in halting efforts in several states to pursue nuclear weapons, near universal adherence, and only one withdrawal (North Korea), the NPT regime is at a critical crossroads. The treaty has proven unable to adapt to new challenges, such as emerging technologies that threaten operational strategic realities, the devolution of state authority to non-state actors and institutions, and growing dissatisfaction with slow pace of nuclear disarmament. Additionally, the treaty leaves open critical questions, including whether or not state parties have the `right' to pursue technologies that allow for domestic production of fuels for nuclear reactors and if modernization programs for nuclear warheads are inconsistent with the treaty. If these questions remain unresolved, the international community will find itself ill prepared to confront emerging proliferation challenges and the NPT, the linchpin of international nonproliferation and disarmament efforts, may begin to erode.

    A 77-year-old woman presented with the complaint of observing her left hand moving without her knowledge while watching television. Her left hand stroked her face and hair as if somebody was controlling it. These movements lasted only half an hour but on recovery, she had left hemiparesis. Alien hand syndrome as the presentation of cardioembolic stroke is extremely rare but can be terrifying to patients. PMID:24982566

  6. Captured by Aliens

    NASA Astrophysics Data System (ADS)

    Achenbach, Joel

    2000-03-01

    Captured by Aliens is a long and twisted voyage from science to the supernatural and back again. I hung out in Roswell, N.M., spent time with the Mars Society, met a guy who was figuring out the best way to build a spaceship to go to Alpha Centauri. I visited the set of the X-Files and talked to Mulder and Scully. One day over breakfast I was told by NASA administrator Dan Goldin, We live in a fog, man! He wants the big answers to the big questions. I spent a night in the base of a huge radio telescope in the boondocks of West Virginia, awaiting the signal from the aliens. I was hypnotized in a hotel room by someone who suspected that I'd been abducted by aliens and that this had triggered my interest in the topic. In the last months of his life, I talked to Carl Sagan, who believed that the galaxy riots with intelligent civilizations. He's my hero, for his steadfast adherence to the scientific method. What I found in all this is that the big question that needs immediate attention is not what's out THERE, but what's going on HERE, on Earth, and why we think the way we do, and how we came to be here in the first place.

  7. Chemical arms treaty's effect on industry noted

    The Chemical Weapons Convention is unique among arms control regimes in terms of its intrusive reach on private industry, especially chemical manufacturers. It requires, among other things, extensive reporting and, in some cases, on-site inspections of commercial facilities. Yet a surprising majority of affected companies are unaware of their obligations under the treaty that could become effective January 1995. A newly released background paper from the Office of Technology Assessment (OTA) intends to correct this situation by fully documenting the effects of the treaty on the U.S. chemical industry. This paper summarizes some of the findings and outlines the legislation required to comply with the Chemical Weapons Convention while still protecting confidential business information and not creating a bureaucratic nightmare for the US chemical industry.

  8. Alienation, authenticity and the self.

    2010-01-01

    While many commentators have held that the concept "alienation" is of crucial importance when attempting to understand human existence, others have held that it is an inherently empty concept that we should abandon. In this article, I refute the latters' charge by showing that each conception of "alienation" is underpinned by a normative ontological conception of the preferable, or authentic, self and show that the concept "alienation" has ethical, existential and socio-political uses. From this I conclude that, when properly understood, the concept "alienation" can provide us with vital insights into human existence.

    The international Minamata Convention on Mercury to protect human health and the environment from anthropogenic emissions and releases of mercury and mercury compounds was formally adopted at a 10 October meeting in Minamata, Japan. The legally binding treaty, currently signed by 92 countries, comes 57 years after the government of Japan officially acknowledged, in 1956, the existence of Minamata disease, which was caused by eating seafood contaminated with methylmercury compounds discharged into Minamata Bay in southern Japan.

    Belief that intelligent life is commonplace in the Universe was taken for granted by scholars and scientists until well into the nineteenth century. Space travel since the late 1950s reignited the debate, which even now attracts discussion by serious, professional scientists. And although statisticians might lobby that life must surely exist somewhere in the Universe, the evolution of what we perceive as 'intelligent life' seems utterly improbable--elsewhere as well as on Earth. Can we free ourselves of our animist fantasies and accept that all alien forms of intelligent life are, and always have been, imaginary?

  18. Characteristics of successful alien plants.

    PubMed

    van Kleunen, M; Dawson, W; Maurel, N

    2015-05-01

    Herbert Baker arguably initiated the search for species characteristics determining alien plant invasion success, with his formulation of the 'ideal weed'. Today, a profusion of studies has tested a myriad of traits for their importance in explaining success of alien plants, but the multiple, not always appropriate, approaches used have led to some confusion and criticism. We argue that a greater understanding of the characteristics explaining alien plant success requires a refined approach that respects the multistage, multiscale nature of the invasion process. We present a schema of questions we can ask regarding the success of alien species, with the answering of one question in the schema being conditional on the answer of preceding questions (thus acknowledging the nested nature of invasion stages). For each question, we identify traits and attributes of species we believe are likely to be most important in explaining species success, and we make predictions as to how we expect successful aliens to differ from natives and from unsuccessful aliens in their characteristics. We organize the findings of empirical studies according to the questions in our schema that they have addressed, to assess the extent to which they support our predictions. We believe that research on plant traits of alien species has already told us a lot about why some alien species become successful after introduction. However, if we ask the right questions at the appropriate scale and use appropriate comparators, research on traits may tell us whether they are really important or not, and if so under which conditions.

  19. Assessing Proposals for New Global Health Treaties: An Analytic Framework

    Røttingen, John-Arne; Frenk, Julio

    2015-01-01

    We have presented an analytic framework and 4 criteria for assessing when global health treaties have reasonable prospects of yielding net positive effects. First, there must be a significant transnational dimension to the problem being addressed. Second, the goals should justify the coercive nature of treaties. Third, proposed global health treaties should have a reasonable chance of achieving benefits. Fourth, treaties should be the best commitment mechanism among the many competing alternatives. Applying this analytic framework to 9 recent calls for new global health treaties revealed that none fully meet the 4 criteria. Efforts aiming to better use or revise existing international instruments may be more productive than is advocating new treaties. PMID:26066926

    1991-01-01

    A study was made of the ratification behavior of 160 countries with respect to 38 global environmental treaties. The study identifies and explains patterns in the ratification of treaties, providing two means of assessing the likelihood that any given country will support global environmental treaties. National ratification totals reveal a pattern of high ratification by countries in Western Europe, North America, Japan, Australia, and New Zealand. A country's standing within the range of high to low ratification rates can be explained by the statistical model developed in the study. This research allows one to identify countries likely to support global environmental treaties.

  2. Alien Hand Syndrome.

    PubMed

    Hassan, Anhar; Josephs, Keith A

    2016-08-01

    Alien hand syndrome (AHS) is a rare disorder of involuntary limb movement together with a sense of loss of limb ownership. It most commonly affects the hand, but can occur in the leg. The anterior (frontal, callosal) and posterior variants are recognized, with distinguishing clinical features and anatomical lesions. Initial descriptions were attributed to stroke and neurosurgical operations, but neurodegenerative causes are now recognized as most common. Structural and functional imaging and clinical studies have implicated the supplementary motor area, pre-supplementary motor area, and their network connections in the frontal variant of AHS, and the inferior parietal lobule and connections in the posterior variant. Several theories are proposed to explain the pathophysiology. Herein, we review the literature to update advances in the understanding of the classification, pathophysiology, etiology, and treatment of AHS.

  3. Dysregulation of CD4(+) T Cell Subsets in Intracranial Aneurysm.

    2016-02-01

    Intracranial aneurysms (IAs) and potential IA rupture are one of the direct causes of permanent brain damage and mortality. Interestingly, the major risk factors of IA development, including hemodynamic stress, hypertension, smoking, and genetic predispositions, are closely associated with a proinflammatory immune status. Therefore, we examined the roles of CD4(+) T cells in IA pathogenesis. IA patients exhibited peripheral CD4(+) T-cell imbalance, with overrepresented T helper 1 (Th1) and Th17 activities and underrepresented Th2 and regulatory T (Treg) activities, including increased IFN-γ, TNF-α, and IL-17 production and decreased IL-10 production from total CD4(+) T cells. Chemokine receptors CXCR3 and CCR6 were used to identify Th1, Th2, and Th17 cell subsets, and CD4(+)CD25(hi) was used to identify Treg cells. Based on these markers, the data then showed altered cytokine production by each cell type and shifted subpopulation frequency. Moreover, this shift in frequency was directly correlated with IA severity. To examine the underlying mechanism of CD4(+) T cell skewing, we cocultured CD4(+) T cells with autologous monocytes and found that coculture with monocytes could significantly increase IFN-γ and IL-17 production through contact-independent mechanisms, demonstrating that monocytes could potentially contribute to the altered CD4(+) T cell composition in IA. Analyzing mRNA transcripts revealed significantly upregulated IL-1β and TNF-α expression by monocytes from IA patients. We found a loss of CD4(+) T cell subset balance that was likely to promote a higher state of inflammation in IA, which may exacerbate the disease through a positive feedback loop.

    Systemic Lupus Erythematosus (SLE) is an autoimmune disease in which autoreactive CD4+ T cells play an essential role. CD4+ T cells rely on glycolysis for inflammatory effector functions, but recent studies have shown that mitochondrial metabolism supports their chronic activation. How these processes contribute to lupus is unclear. Here, we show that both glycolysis and mitochondrial oxidative metabolism are elevated in CD4+ T cells from lupus-prone B6.Sle1.Sle2.Sle3 (TC) mice as compared to non-autoimmune controls. In vitro, both the mitochondrial metabolism inhibitor metformin and the glucose metabolism inhibitor 2-Deoxy-D-glucose (2DG) reduced IFNγ production, although at different stages of activation. Metformin also restored the defective IL-2 production by TC CD4+ T cells. In vivo, treatment of TC mice and other lupus models with a combination of metformin and 2DG normalized T cell metabolism and reversed disease biomarkers. Further, CD4+ T cells from SLE patients also exhibited enhanced glycolysis and mitochondrial metabolism that correlated with their activation status, and their excessive IFNγ production was significantly reduced by metformin in vitro. These results suggest that normalization of T cell metabolism through the dual inhibition of glycolysis and mitochondrial metabolism is a promising therapeutic venue for SLE. PMID:25673763

  12. Trade treaties and alcohol advertising policy.

    PubMed

    Gould, Ellen

    2005-09-01

    Restrictions on alcohol advertising are vulnerable to challenge under international trade agreements. As countries negotiate new trade treaties and expand the scope of existing ones, the risk of such a challenge increases. While alcohol advertising restrictions normally do not distinguish between foreign and domestic products, this neutral character does not protect them from being challenged under trade rules. The article analyzes four provisions of trade agreements--expropriation, de facto discrimination, market access, and necessity--in relation to the jeopardy they pose for alcohol advertising restrictions. Key cases are reviewed to illustrate how these provisions have been used to either overturn existing advertising restrictions or prevent new ones from coming into force. The article also reports on the mixed results governments have had in trying to justify their regulations to trade panels and the stringent criteria imposed for proving that a regulation is "necessary."

  13. National security and the comprehensive test ban treaty

    1980-08-01

    For nearly three years now, the US, UK, and USSR have been working on the draft of a treaty that would ban all nuclear explosions (both peaceful applications and weapon tests) and institute verification and monitoring provisions to ensure compliance with the treaty. The status of the draft treaty is summarized. The question, Is a CTBT really in the interest of US national security. is analyzed with arguments used by both proponents and opponents of the CTBT. It is concluded that there are arguments both for and against a CTBT, but, for those whose approach to national security can be expressed as peace through preparedness, the arguments against a CTBT appear persuasive.

    1996-09-01

    On September 24, the Comprehensive Test Ban Treaty (CTBT) was formally opened for signature at the United Nations in New York. In the following days, 94 countries signed the treaty including the five nuclear-weapon states (the United States, Russia, China, France and Britain) and Israel, one of the three so-called {open_quotes}threshold{close_quotes} states. Although prospects for the CTBT`s formal entry into force remain uncertain because of India`s refusal to sign, the signing of treaty may nevertheless effectively preclude an future nuclear tests.

  20. CD4 T-cell memory generation and maintenance.

    PubMed

    Gasper, David J; Tejera, Melba Marie; Suresh, M

    2014-01-01

    Immunologic memory is the adaptive immune system's powerful ability to remember a previous antigen encounter and react with accelerated vigor upon antigen re-exposure. It provides durable protection against reinfection with pathogens and is the foundation for vaccine-induced immunity. Unlike the relatively restricted immunologic purview of memory B cells and CD8 T cells, the field of CD4 T-cell memory must account for multiple distinct lineages with diverse effector functions, the issue of lineage commitment and plasticity, and the variable distribution of memory cells within each lineage. Here, we discuss the evidence for lineage-specific CD4 T-cell memory and summarize the known factors contributing to memory-cell generation, plasticity, and long-term maintenance.

  14. Senate hearing considers Law of the Sea treaty

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

    2012-06-01

    The U.S. Senate Committee on Foreign Relations is once again discussing the Law of the Sea Convention (LOS). The treaty, which was adopted in 1982 by parties to a United Nations Conference as a framework for governing uses of the world's oceans, has been ratified by more than 160 countries, but the United States is a notable exception. The treaty has been approved twice by the Foreign Relations Committee but has not made it to a full Senate vote because of opponents' concerns about potential loss of U.S. sovereignty and U.S. access to the deep seabed, among other reasons. During a 23 May hearing of the committee, chairman John Kerry (D-Mass.), a strong supporter of the treaty, said U.S. ratification "is now more urgent than ever" and that to remain outside of the treaty "is fundamentally, directly counter to the best interests" of the United States.

  15. Highly capable theater missile defenses and the ABM Treaty

    SciTech Connect

    Gronlund, L.; Lewis, G.; Postol, T.; Wright, D.

    1994-04-01

    Since 1972 the Anti-Ballistic Missile (ABM) Treaty has been one of the fundamental building blocks of U.S.-Soviet and U.S.-Russian arms control efforts. By severely restricting the deployment of defensive systems that could undermine deterrent capabilities, the ABM Treaty removed a potential incentive to increase strategic nuclear forces and allowed substantial force reductions to be negotiated in the START I and II agreements. Although the Cold War has ended, the treaty may still have important roles today and in the future. In particular, future deep reductions in U.S. and Russian strategic forces, as well as in the nuclear forces of other countries, may be impossible without the assurance granted by the treaty.

    The Non-Proliferation Treaty rests on a basic bargain between the five declared nuclear-weapon states-the United States, Russia, Britain, France and China and 167 states that do not possess nuclear weapons. In addition, to the arms control and disarmaments commitments in Article VI, the parties pledge in the treaty`s pramble their determination to seek a comprehensive test ban (CTB) and express the understanding that in connection with the treaty on general and complete disarmament the parties should seek the cessation of manufacture of nuclear weapons, the liquidation of all their existing stock piles, and the elimination from national arsenals of nuclear weapons and means of their delivery. The author summaries key elements of these agreements.

    NASA Astrophysics Data System (ADS)

    Orych, Agata

    2015-06-01

    The Open Skies Treaty has been a peace-building instrument between North American and European nations for over two decades. This agreement is based on the possibility for each country-signatory of the Treaty to independently conduct observation flights and obtain aerial imagery data of the territories of other Treaty States-Parties. This imagery data was originally acquired only using traditional photographic film cameras. Together with the rapid development and advancement of digital sensor technologies, the logical step forward was to amend the Treaty provisions to allow for the use of these types of sensors during observation missions. This paper describes this transition process and highlights a number of technical problems which needed to be addressed by experts working within the Open Skies Consultative Commission workgroups.

  19. CD4+ T Cells: guardians of the phagosome.

    PubMed

    Tubo, Noah J; Jenkins, Marc K

    2014-04-01

    CD4(+) T cells are key cells of the adaptive immune system that use T cell antigen receptors to recognize peptides that are generated in endosomes or phagosomes and displayed on the host cell surface bound to major histocompatibility complex molecules. These T cells participate in immune responses that protect hosts from microbes such as Mycobacterium tuberculosis, Cryptococcus neoformans, Leishmania major, and Salmonella enterica, which have evolved to live in the phagosomes of macrophages and dendritic cells. Here, we review studies indicating that CD4(+) T cells control phagosomal infections asymptomatically in most individuals by secreting cytokines that activate the microbicidal activities of infected phagocytes but in a way that inhibits the pathogen but does not eliminate it. Indeed, we make the case that localized, controlled, persistent infection is necessary to maintain large numbers of CD4(+) effector T cells in a state of activation needed to eradicate systemic and more pathogenic forms of the infection. Finally, we posit that current vaccines for phagosomal infections fail because they do not produce this "periodic reminder" form of CD4(+) T cell-mediated immune control.

    2014-01-01

    Barrier sites such as the gastrointestinal tract are in constant contact with the environment, which contains both beneficial and harmful components. The immune system at the epithelia must make the distinction between these components to balance tolerance, protection, and immunopathology. This is achieved via multifaceted immune recognition, highly organized lymphoid structures, and the interaction of many types of immune cells. The adaptive immune response in the gut is orchestrated by CD4+ helper T (Th) cells, which are integral to gut immunity. In recent years, it has become apparent that the functional identity of these Th cells is not as fixed as initially thought. Plasticity in differentiated T cell subsets has now been firmly established, in both health and disease. The gut, in particular, utilizes CD4+ T cell plasticity to mold CD4+ T cell phenotypes to maintain its finely poised balance of tolerance and inflammation and to encourage biodiversity within the enteric microbiome. In this review, we will discuss intestinal helper T cell plasticity and our current understanding of its mechanisms, including our growing knowledge of an evolutionarily ancient symbiosis between microbiota and malleable CD4+ T cell effectors.

    This work reports the preliminary results of the first human images at the new high-field benchmark of 9.4T. A 65-cm-diameter bore magnet was used together with an asymmetric 40-cm-diameter head gradient and shim set. A multichannel transmission line (transverse electromagnetic (TEM)) head coil was driven by a programmable parallel transceiver to control the relative phase and magnitude of each channel independently. These new RF field control methods facilitated compensation for RF artifacts attributed to destructive interference patterns, in order to achieve homogeneous 9.4T head images or localize anatomic targets. Prior to FDA investigational device exemptions (IDEs) and internal review board (IRB)-approved human studies, preliminary RF safety studies were performed on porcine models. These data are reported together with exit interview results from the first 44 human volunteers. Although several points for improvement are discussed, the preliminary results demonstrate the feasibility of safe and successful human imaging at 9.4T. PMID:17075852

  8. Searching for Alien Life Having Unearthly Biochemistry

    NASA Technical Reports Server (NTRS)

    Jones, Harry

    2003-01-01

    The search for alien life in the solar system should include exploring unearth-like environments for life having an unearthly biochemistry. We expect alien life to conform to the same basic chemical and ecological constraints as terrestrial life, since inorganic chemistry and the laws of ecosystems appear to be universal. Astrobiologists usually assume alien life will use familiar terrestrial biochemistry and therefore hope to find alien life by searching near water or by supplying hydrocarbons. The assumption that alien life is likely to be based on carbon and water is traditional and plausible. It justifies high priority for missions to search for alien life on Mars and Europa, but it unduly restricts the search for alien life. Terrestrial carbon-water biochemistry is not possible on most of the bodies of our solar system, but all alien life is not necessarily based on terrestrial biochemistry. If alien life has a separate origin from Earth life, and if can survive in an environment extremely different from Earth's, then alien life may have unearthly biochemistry. There may be other solvents than water that support alien life and other elements than carbon that form complex life enabling chain molecules. Rather than making the exploration-restricting assumption that all life requires carbon, water, and terrestrial biochemistry, we should make the exploration-friendly assumption that indigenous, environmentally adapted, alien life forms might flourish using unearthly biochemistry in many places in the solar system. Alien life might be found wherever there is free energy and a physical/chemical system capable of using that energy to build living structures. Alien life may be discovered by the detection of some general non-equilibrium chemistry rather than of terrestrial biochemistry. We should explore all the potential abodes of life in the solar system, including those where life based on terrestrial biochemistry can not exist.

    MHC class II-expressing thymocytes and thymic epithelial cells can mediate CD4 T-cell selection resulting in functionally distinct thymocyte-selected CD4 (T-CD4) and epithelial-selected CD4 (E-CD4) T cells, respectively. However, little is known about how T-cell receptor (TCR) signaling influences the development of these two CD4 T-cell subsets. To study TCR signaling for T-CD4 T-cell development, we used a GFP reporter system of Nur77 in which GFP intensity directly correlates with TCR signaling strength. T-CD4 T cells expressed higher levels of GFP than E-CD4 T cells, suggesting that T-CD4 T cells received stronger TCR signaling than E-CD4 T cells during selection. Elimination of Ras GTPase-activating protein enhanced E-CD4 but decreased T-CD4 T-cell selection efficiency, suggesting a shift to negative selection. Conversely, the absence of IL-2-inducible T-cell kinase that causes poor E-CD4 T-cell selection due to insufficient TCR signaling improved T-CD4 T-cell generation, consistent with rescue from negative selection. Strong TCR signaling during T-CD4 T-cell development correlates with the expression of the transcription factor promyelocytic leukemia zinc finger protein. However, although modulation of the signaling strength affected the efficiency of T-CD4 T-cell development during positive and negative selection, the signaling strength is not as important for the effector function of T-CD4 T cells. These findings indicate that innate T-CD4 T cells, together with invariant natural killer T cells and γδ T cells, receive strong TCR signals during their development and that signaling requirements for the development and the effector functions are distinct.

    The immune system is suggested to be essential in vascular remodeling and stiffening. To study the dependence upon lymphocytes in vascular stiffening, we compared an angiotensin II-model of vascular stiffening in normal C57BL/6J mice with lymphocyte-deficient RAG 1(-/-) mice and additionally characterized the component of vascular stiffness due to vasoconstriction vs. vascular remodeling. Chronic angiotensin II increased aortic pulse wave velocity, effective wall stiffness, and effective Young's modulus in C57BL/6J mice by three-fold but caused no change in the RAG 1(-/-) mice. These functional measurements were supported by aortic morphometric analysis. Adoptive transfer of CD4(+) T helper lymphocytes restored the angiotensin II-mediated aortic stiffening in the RAG 1(-/-) mice. In order to account for the hydraulic vs. material effects of angiotensin II on pulse wave velocity, subcutaneous osmotic pumps were removed after 21 days of angiotensin II-infusion in the WT mice to achieve normotensive values. The pulse wave velocity (PWV) decreased from three- to two-fold above baseline values up to 7 days following pump removal. This study supports the pivotal role of the CD4(+) T-lymphocytes in angiotensin II-mediated vascular stiffening and that angiotensin II-mediated aortic stiffening is due to the additive effect of active vascular smooth muscle vasoconstriction and vascular remodeling.

  12. Rush-Bagot and the upkeep of arms treaties

    SciTech Connect

    O'Neill, B. )

    1991-09-01

    Signing an arms treaty after a long negotiation brings a great sense of completion, but that is only the beginning. Living under a treaty - implementing it, resolving different interpretations and compliance disputes, adapting it to changed times - is itself a continuing negotiating process. Handling this process poorly can greatly undermine the original agreement. But nurturing a treaty properly can strengthen it and keep it effective in new circumstances. The history of the Rush-Bagot Agreement of 1817, which limited warships on the Great Lakes, provides examples of many of the problems that can come up. It was violated, subjected to proportional responses, threatened with unilateral reinterpretation and abrogation, modified by executive agreement, and violated again. It proved hard to kill, but ultimately these successive traumas compromised its purpose and value. Indeed, continual threats and violations worsened the rancor between the US and Canada. Today, what influence the agreement still has on restraining armaments on the lakes flows mainly from its symbolism; although the agreement remains in force, none of its original provisions are currently observed. In many ways - violations, untenable reinterpretations, proposals for proportionate responses, claims of technological obsolescence - the Rush-Bagot experience foreshadowed the Antiballistic Missile (ABM) Treaty's troubles over the past decade. But the ABM Treaty's drafters built in provisions to deal with such problems. The Rush-Bagot experience offers lessons for managing today's accords - but largely lessons in what not to do.

  8. Alien liquid detector and control

    SciTech Connect

    Potter, B.M.

    1980-09-02

    An alien liquid detector employs a monitoring element and an energizing circuit for maintaining the temperature of the monitoring element substantially above ambient temperature. For this purpose an electronic circit controls a flow of heating current to the monitoring element. The presence of an alien liquid is detected by sensing a predetermined change in heating current flow to the monitoring element, e.g., to distinguish between water and oil. In preferred embodiments the monitoring element is a thermistor whose resistance is compared with a reference resistance and heating current through the thermistor is controlled in accordance with the difference. In one embodiment a bridge circuit senses the resistance difference; the difference may be sensed by an operational amplifier arrangement. Features of the invention include positioning the monitoring element at the surface of water, slightly immersed, so that the power required to maintain the thermistor temperature substantially above ambient temperature serves to detect presence of oil pollution at the surface.

  11. Control of inflammatory heart disease by CD4+ T cells.

    PubMed

    Barin, Jobert G; Čiháková, Daniela

    2013-05-01

    This review focuses on autoimmune myocarditis and its sequela, inflammatory dilated cardiomyopathy (DCMI), and the inflammatory and immune mechanisms underlying the pathogenesis of these diseases. Several mouse models of myocarditis and DCMI have improved our knowledge of the pathogenesis of these diseases, informing more general problems of cardiac remodeling and heart failure. CD4(+) T cells are critical in driving the pathogenesis of myocarditis. We discuss in detail the role of T helper cell subtypes in the pathogenesis of myocarditis, the biology of T cell-derived effector cytokines, and the participation of other leukocytic effectors in mediating disease pathophysiology. We discuss interactions between these subsets in both suppressive and collaborative fashions. These findings indicate that cardiac inflammatory disease, and autoimmunity in general, may be more diverse in divergent effector mechanisms than has previously been appreciated.

  12. Acoustic noise reduction in a 4 T MRI scanner.

    PubMed

    Mechefske, Chris K; Geris, Ryan; Gati, Joseph S; Rutt, Brian K

    2002-01-01

    High-field, high-speed magnetic resonance imaging (MRI) can generate high levels of noise. There is ongoing concern in the medical and imaging research communities regarding the detrimental effects of high acoustic levels on auditory function, patient anxiety, verbal communication between patients and health care workers and ultimately MR image quality. In order to effectively suppress the noise levels inside MRI scanners, the sound field needs to be accurately measured and characterized. This paper presents the results of measurements of the sound radiation from a gradient coil cylinder within a 4 T MRI scanner under a variety of conditions. These measurement results show: (1) that noise levels can be significantly reduced through the use of an appropriately designed passive acoustic liner; and (2) the true noise levels that are experienced by patients during echo planar imaging.

    Human beings are exposed to a variety of different pathogens, which induce tailored immune responses and consequently generate highly diverse populations of pathogen-specific T cells. CD4+ T cells have a central role in adaptive immunity, since they provide essential help for both cytotoxic T cell- and antibody-mediated responses. In addition, CD4+ regulatory T cells are required to maintain self-tolerance and to inhibit immune responses that could damage the host. Initially, two subsets of CD4+ helper T cells were identified that secrete characteristic effector cytokines and mediate responses against different types of pathogens, i.e., IFN-γ secreting Th1 cells that fight intracellular pathogens, and IL-4 producing Th2 cells that target extracellular parasites. It is now well established that this dichotomy is insufficient to describe the complexity of CD4+ T cell differentiation, and in particular the human CD4 compartment contains a myriad of T cell subsets with characteristic capacities to produce cytokines and to home to involved tissues. Moreover, it has become increasingly clear that these T cell subsets are not all terminally differentiated cells, but that the majority is plastic and that in particular central memory T cells can acquire different properties and functions in secondary immune responses. In addition, there is compelling evidence that helper T cells can acquire regulatory functions upon chronic stimulation in inflamed tissues. The plasticity of antigen-experienced human T cell subsets is highly relevant for translational medicine, since it opens new perspectives for immune-modulatory therapies for chronic infections, autoimmune diseases, and cancer.

  14. Clinton advocates for Law of the Sea treaty

    NASA Astrophysics Data System (ADS)

    Showstack, Randy

    The Obama administration recently reiterated its call for the United States to ratify the United Nations Convention on the Law of the Sea. U.S. secretary of state Hillary Clinton, who expressed strong support for the Law of the Sea treaty during her Senate confirmation hearing in 2009, again called for passage of the treaty during 15 December remarks at a business roundtable in Washington, D. C., sponsored by the Pew Charitable Trusts. "Signing on to the convention is critical to protecting American security and enhancing our economic strength," she said, noting that the U.S. ratification of the treaty would protect American business interests by providing "legal certainty and predictability that businesses can rely on." The treaty—which also touches on a wide range of other issues including navigation, conservation and management of resources, and scientific research—is opposed by some who are concerned about the undermining of national sovereignty.

  15. Challenge inspections in Arms Control treaties: Any lessons for strengthening NPT verification. [Non-Proliferation Treaty (NPT)

    SciTech Connect

    Allentuck, J.

    1992-01-01

    Recent revelations of an ongoing and sophisticated nuclear weapons development program in Iraq have lead to suggestions for strengthening International Atomic Energy Agency (IAEA) safeguards. Especially troubling was the realization that safeguards, as presently applied, could not possibly have detected such a program. It is clear that the inspections which have taken place in Iraq since the Gulf War could only have been imposed on a nation which had suffered a severe military defeat. It has, however, been argued that challenge or challenge like'' inspections already incorporated in or proposed for the Treaty on Conventional Armed Forces in Europe (the CFE Treaty) the Chemical Weapons Convention (CWC) and the Treaty Between the United States and the USSR on the Reduction and Limitation of Strategic offensive Arms (START) might serve as models for enhanced special inspections in the Treaty on the Non-Proliferation of Nuclear Weapons (the NPT). The expectation that none of the challenge or challenge like inspections in the above treaties would provide a model for the NPT was confirmed although certain characteristics of these inspections do provide useful points of departure. Although the context of challenge inspections in CWC bears substantial similarity to the NPT, it is from the provisions for suspect-site'' and formerly declared site'', challenge like inspections in START that innovative ideas for strengthening special inspections in NPT may be derived.

  9. The Nuclear Non-Proliferation Treaty and the Comprehensive Nuclear-Test-Ban Treaty, the relationship

    NASA Astrophysics Data System (ADS)

    Graham, Thomas, Jr.

    2014-05-01

    The Nuclear Non-Proliferation Treaty (NPT) is the most important international security arrangement that we have that is protecting the world community and this has been true for many years. But it did not happen by accident, it is a strategic bargain in which 184 states gave up the right forever to acquire the most powerful weapon ever created in exchange for a commitment from the five states allowed to keep nuclear weapons under the NPT (U.S., U.K., Russia, France and China), to share peaceful nuclear technology and to engage in disarmament negotiations aimed at the ultimate elimination of their nuclear stockpiles. The most important part of this is the comprehensive nuclear test ban (CTBT); the thinking by the 184 NPT non-nuclear weapon states was and is that they understand that the elimination of nuclear weapon stockpiles is a long way off, but at least the NPT nuclear weapon states could stop testing the weapons. The CTBT has been ratified by 161 states but by its terms it can only come into force if 44 nuclear potential states ratify; 36 have of the 44 have ratified it, the remaining eight include the United States and seven others, most of whom are in effect waiting for the United States. No state has tested a nuclear weapon-except for complete outlier North Korea-in 15 years. There appears to be no chance that the U.S. Senate will approve the CTBT for ratification in the foreseeable future, but the NPT may not survive without it. Perhaps it is time to consider an interim measure, for the UN Security Council to declare that any future nuclear weapon test any time, anywhere is a "threat to peace and security", in effect a violation of international law, which in today's world it clearly would be.

  13. Proposal for revisions of the United Nations Moon Treaty

    NASA Astrophysics Data System (ADS)

    Fernandes, Vera; Abreu, Neyda; Fritz, J.; Knapmeyer, Martin; Smeenk, Lisa; Ten Kate, Inge; Trüninger, Monica

    During this new 2010-decade, it will be imperative to reconsider the effectiveness of the current United Nations (U.N.) Moon Treaty (c.1979). Amendments are necessary to underline the mandatory human stewardship of this fragile planetary body of our Solar System, indispensible to life on Earth. After the very successful Apollo and Luna missions to the Moon (ending in 1976), which brought a wide array of data (samples, surface and orbital experiments), the Moon lost its exploratory attraction in favor of other programs, such as the International Space Station and potential human exploration of Mars. However, since the mid-90's, the enthusiasm for the Moon has been revived, which resulted in several space agencies worldwide (NASA, ESA, ISRO, JAXA, and the Chinese Space Agency) having made great efforts to re-start ex-ploratory and scientific campaigns even though budgetary changes may delay the process. As a result, a wide array of peoples and their interests are put together in each mission planned to reach the Moon (e.g., orbiters and landers). Up to now, mission plans focus on technical requirements and the desires of scientists and engineers, but hardly any other aspects. Field specialists on issues regarding the social, economic, political, cultural, ethical and environmen-tal impacts of Moon exploration and colonization have had little to no involvement in current and past lunar missions. However, these fields would provide different and essential points of view regarding the planning of lunar missions. Moreover, recent documents written by the scientific community, such as "The Scientific Context for Exploration of the Moon: Final Re-port" Committee on the Scientific Context for Exploration of the Moon, National Research Council (2007), or the recent (summer 2009) White Papers for the National Research Council Planetary Science Decadal Survey 2011-2020, do not seem to leave space for a multidisciplinary approach regarding the future lunar exploration either

  14. Does ratification of human-rights treaties have effects on population health?

    2009-06-06

    Human-rights treaties indicate a country's commitment to human rights. Here, we assess whether ratification of human-rights treaties is associated with improved health and social indicators. Data for health (including HIV prevalence, and maternal, infant, and child [<5 years] mortalities) and social indicators (child labour, human development index, sex gap, and corruption index), gathered from 170 countries, showed no consistent associations between ratification of human-rights treaties and health or social outcomes. Established market economy states had consistently improved health compared with less wealthy settings, but this was not associated with treaty ratification. The status of treaty ratification alone is not a good indicator of the realisation of the right to health. We suggest the need for stringent requirements for ratification of treaties, improved accountability mechanisms to monitor compliance of states with treaty obligations, and financial assistance to support the realisation of the right to health.

  15. A seismic event analyzer for nuclear test ban treaty verification

    This paper presents an expert system that interprets seismic data from Norway's regional seismic array, NORESS, for underground nuclear weapons test ban treaty verification. Three important aspects of the expert system are (1) it emulates the problem solving behavior of the human seismic analyst using an Assumption Based Truth Maintenance System, (2) it acts as an assistant to the human analyst by automatically interpreting and presenting events for review, and (3) it enables the analyst to interactively query the system's chain of reasoning and manually perform and interpretation. The general problem of seismic treaty verification is described. The expert system is presented in terms of knowledge representation structures, assumption based reasoning system, user interface elements, and initial performance results. 8 refs., 10 figs., 2 tabs.

  16. Scope and verification of a Fissile Material (Cutoff) Treaty

    SciTech Connect

    Hippel, Frank N. von

    2014-05-09

    A Fissile Material Cutoff Treaty (FMCT) would ban the production of fissile material - in practice highly-enriched uranium and separated plutonium - for weapons. It has been supported by strong majorities in the United Nations. After it comes into force, newly produced fissile materials could only be produced under international - most likely International Atomic Energy Agency - monitoring. Many non-weapon states argue that the treaty should also place under safeguards pre-existing stocks of fissile material in civilian use or declared excess for weapons so as to make nuclear-weapons reductions irreversible. This paper discusses the scope of the FMCT, the ability to detect clandestine production and verification challenges in the nuclear-weapons states.

  19. Who's bound by the former Soviet Union's arms control treaties

    SciTech Connect

    Rhinelander, J.B.; Bunn, G.

    1991-12-01

    A crucial issue raised by the disintegration of the Soviet central government is what happens to Soviet arms control obligations. As the Soviet government transforms or collapses in the wake of the failed August coup, which of the resulting entities will be bound by the treaties the Soviet Union entered into Under international law, the obligations of a state are not affected by even such dramatic changes in government. No one yet knows, however, what the end result of the ongoing devolution of power in the erstwhile Soviet Union will be. As illustrations of what could happen to Soviet arms control obligations - not predictions of the future - the authors pose two alternative scenarios. In the first, they assume that most of the current 12 republics, including all of the big four where substantial nuclear forces and the largest conventional forces are located (Russia, Ukraine, Khazakhstan, and Belarus), ultimately form a loose confederation with sufficient central authority to be called a nation-state and to carry out the essence of Soviet obligations under major arms control treaties. In the second, they assume that the union disintegrates further, with these four key republics seceding entirely and recognizing one another as independent states - a step which is apparently one of the US criteria for granting its own recognition. In this scenario, the Russian republic maintains its basic territory and replaces the central government as the power center for military and foreign affairs. In each of these cases, they will describe the general issues affecting the Soviet Union's international obligations, and consider specifically the two most important arms control agreements now in force - the multilateral nuclear Non-proliferation Treaty (NPT) and the bilateral Antiballistic Missile (ABM) Treaty.

    Although the last few months have seen a number of positive steps in arms control-the start of negotiations for a comprehensive test ban treaty, the extension of the U.S. nuclear testing moratorium through September 1995, an ingenious trilateral deal with Kiev and Moscow to move along the denuclerization of Ukraine, and agreement in principle to the reciprocal monitoring of U.S. and Russian plutonium storage facilities-two potential policy changes in Washington could undercut these developments.

  8. Hosts and parasites as aliens.

    2006-06-01

    Over the past decades, various free-living animals (hosts) and their parasites have invaded recipient areas in which they had not previously occurred, thus gaining the status of aliens or exotics. In general this happened to a low extent for hundreds of years. With variable frequency, invasions have been followed by the dispersal and establishment of non-indigenous species, whether host or parasite. In the literature thus far, colonizations by both hosts and parasites have not been treated and reviewed together, although both are usually interwoven in various ways. As to those factors permitting invasive success and colonization strength, various hypotheses have been put forward depending on the scientific background of respective authors and on the conspicuousness of certain invasions. Researchers who have tried to analyse characteristic developmental patterns, the speed of dispersal or the degree of genetic divergence in populations of alien species have come to different conclusions. Among parasitologists, the applied aspects of parasite invasions, such as the negative effects on economically important hosts, have long been at the centre of interest. In this contribution, invasions by hosts as well as parasites are considered comparatively, revealing many similarities and a few differences. Two helminths, the liver fluke, Fasciola hepatica, of cattle and sheep and the swimbladder nematode, Anguillicola crassus, of eels are shown to be useful as model parasites for the study of animal invasions and environmental global change. Introductions of F. hepatica have been associated with imports of cattle or other grazing animals. In various target areas, susceptible lymnaeid snails serving as intermediate hosts were either naturally present and/or were introduced from the donor continent of the parasite (Europe) and/or from other regions which were not within the original range of the parasite, partly reflecting progressive stages of a global biota change.

    Question regarding the ABM Treaty likely to arise fall into 3 main categories: (1) even elimination of the Krasnoyarsk radar will leave some ambiguities in the ABM Treaty's treatment of large phased-array radars (LPARs); agreed clarifications might help forestall future disagreements; (2) continuing issues are likely to be raised by the overlap between ABM and non-AMB technologies, such as air defense or antisatellite (ASAT) weapons; and (3) more specific limitations must be developed for new technologies, such as the lasers and infrared sensors under development in the SDI program. The fundamental criteria for judging proposed solutions to these problems are their ability to achieve the basic goals of the ABM Treaty in a verifiable manner, without unduly interfering with other important military or civilian missions, such as early warning or air defense, or with continued research on ABM. (Military missions whose restraint is desirable for other reasons, such as ASAT, might be limited without under-mining U.S. security). As with the original ABM negotiation, the goal must be to ensure that militarily significant nationwide ABM systems are prohibited, and that neither side can develop a ready base for quickly deploying such a nationwide system - whether by rapidly building additional ABM components, or by upgrading ostensibly non-ABM systems to have an ABM systems to have an ABM capability - without clearly and observably violating the accord.

    1987-01-01

    This study examines how the ABM Treaty restraints and the arms control process that was a logical continuation of the ABM Treaty have effected US ballistic-missile defense programs from 1972 to 1986, including the Strategic Defense Initiative. It provides a thorough analysis of US ABM Treaty negotiating objectives and outcomes, concluding that the conceptual linkage between offense and defense established early in SALT was broken and never reforged in later negotiations or agreements. It examines how Soviet views of strategic defense differ from the US, and how those views are reflected in Soviet strategic defense programs. It concludes that the Soviet understanding is diametrically opposed to the US view of the ABM Treaty, and that this has contributed to the great disparity in strategic defense effort since the signing of the Treaty. Finally, US BMD programs are examined in detail both to set out a general history of their development and to examine specifically the ABM Treaty's effect on that development. US Programs were effected by the ABM Treaty's logic and spirit as much as they were constrained by specific limitations. The Strategic Defense Initiative has been similarly hampered by being entangled in the US-Soviet strategic arms control process. The thesis concludes with a review of alternative approaches to the ABM Treaty regime.

    Suppression of CD8 and CD4 T cells is a hallmark in chronic viral infections, including hepatitis C and HIV. While multiple pathways are known to inhibit CD8 T cells, the host molecules that restrict CD4 T cell responses are less understood. Here, we used inducible and CD4 T cell–specific deletion of the gene encoding the TGF-β receptor during chronic lymphocytic choriomeningitis virus infection in mice, and determined that TGF-β signaling restricted proliferation and terminal differentiation of antiviral CD4 T cells. TGF-β signaling also inhibited a cytotoxic program that includes granzymes and perforin expression at both early and late stages of infection in vivo and repressed the transcription factor eomesodermin. Overexpression of eomesodermin was sufficient to recapitulate in great part the phenotype of TGF-β receptor–deficient CD4 T cells, while SMAD4 was necessary for CD4 T cell accumulation and differentiation. TGF-β signaling also restricted accumulation and differentiation of CD4 T cells and reduced the expression of cytotoxic molecules in mice and humans infected with other persistent viruses. These data uncovered an eomesodermin-driven CD4 T cell program that is continuously suppressed by TGF-β signaling. During chronic viral infection, this program limits CD4 T cell responses while maintaining CD4 T helper cell identity. PMID:27599295

    HIV infection is associated with depletion of CD4(+) T cells. The mechanisms of this phenomenon remain to be understood. In particular, it remains controversial whether and to what extent uninfected ("bystander") CD4(+) T cells die in HIV-infected individuals. We address this question using a system of human lymphoid tissue ex vivo. Tissue blocks were inoculated with HIV-1. After productive infection was established, they were treated with the reverse transcriptase inhibitor nevirapine to protect from infection those CD4(+) T cells that had not yet been infected. These CD4(+) T cells residing in HIV-infected tissue are by definition bystanders. Our results demonstrate that after nevirapine application the number of bystander CD4(+) T cells is conserved. Thus, in the context of HIV-infected human lymphoid tissue, productive HIV infection kills infected cells but is not sufficient to cause the death of a significant number of uninfected CD4(+) T cells.

    Under the Columbia River Treaty (Treaty or CRT) of 1964, Canada and the United States (U.S.) jointly regulate and manage the Columbia River as it flows from British Columbia into the U.S. The Treaty has provided substantial flood control and power generation benefits to both nations. The Treaty established Canadian and U.S. Entities as implementing agents for each government. British Columbia Hydro and Power Authority (BC Hydro) was designated as the Canadian Entity. The Bonneville Power Administration (BPA) Administrator and the U.S. Army Corps of Engineers (Corps) Division Engineer, Northwestern Division, were designated as the U.S. Entity. The Canadian and U.S. Entities are empowered by their respective governments with broad discretion to implement the existing Columbia River Treaty. They are not, however, authorized to terminate, renegotiate, or otherwise modify the Treaty. In the U.S., authority over international treaties rests with the President, assisted in foreign relations and international negotiations by the Department of State and subject in certain cases to the advice and consent of the U.S. Senate. In Canada, international treaties are within the prerogative of the executive branch of the federal government. Under current policy, treaties are tabled in the House of Commons, and are subject to a waiting period before the executive branch brings the treaty into effect. In the case of the Columbia River Treaty, Canada has assigned certain rights and obligations relating to the Treaty to British Columbia pursuant to the Canada-B.C. Agreement. The Phase 1 report is provided to those respective governmental bodies to support possible independent and/or joint decisions that may be made with respect to the future of the Treaty. The Treaty contains two important provisions that take effect on and after September 16, 2024, that could impact the current power and flood control benefits: 1.

    IL-17+ CD4+ T (Th17) cells contribute to the pathogenesis of several human inflammatory diseases. Here we demonstrate that TNF inhibitor (TNFi) drugs induce the anti-inflammatory cytokine IL-10 in CD4+ T cells including IL-17+ CD4+ T cells. TNFi-mediated induction of IL-10 in IL-17+ CD4+ T cells is Treg-/Foxp3-independent, requires IL-10 and is overcome by IL-1β. TNFi-exposed IL-17+ CD4+ T cells are molecularly and functionally distinct, with a unique gene signature characterized by expression of IL10 and IKZF3 (encoding Aiolos). We show that Aiolos binds conserved regions in the IL10 locus in IL-17+ CD4+ T cells. Furthermore, IKZF3 and IL10 expression levels correlate in primary CD4+ T cells and Aiolos overexpression is sufficient to drive IL10 in these cells. Our data demonstrate that TNF-α blockade induces IL-10 in CD4+ T cells including Th17 cells and suggest a role for the transcription factor Aiolos in the regulation of IL-10 in CD4+ T cells.

    The objective of this study was to establish mean CD4+ T cell values among healthy Javanese adults in Indonesia. Two hundred forty-one healthy adults (119 women and 122 men), aged 18-65 years, were enrolled in the study. CD4+ T cells were analyzed by immunophenotyping. The mean absolute CD4+ T cell count was 753.3 ± 270.3 cells/µl (median = 725.0 cells/µl) and the mean CD4+ T cell percentage was 32.6 ± 7.7%, (median = 31.0%). Women had a slightly higher mean absolute CD4+ T cell count and CD4+ T cell percentage (779.1 ± 271.0 cells/ µl; 33.4 ± 8.2%) than men (728.2 ± 268.3 cells/µl; 31.8 ± 7.1%), but the differences were not statistically significant (p = 0.126, p = 0.216, respectively). The mean absolute CD4+ T cell varied significantly by age group (p = 0.002). Sixty-one point seven percent of men studied (37/60) had a CD4+ T cell count less than 500 cells/µl (OR 1.8; 95% CI = 1.001-3.300). Absolute CD4+ T cell counts among Javanese Indonesians varied significantly by age.

    Recent studies have identified a subset of memory T cells with stem cell-like properties (T(SCM)) that include increased longevity and proliferative potential. In this study, we examined the dynamics of CD4(+) T(SCM) during pathogenic SIV infection of rhesus macaques (RM) and nonpathogenic SIV infection of sooty mangabeys (SM). Whereas SIV-infected RM show selective numeric preservation of CD4(+) T(SCM), SIV infection induced a complex perturbation of these cells defined by depletion of CD4(+)CCR5(+) T(SCM), increased rates of CD4(+) T(SCM) proliferation, and high levels of direct virus infection. The increased rates of CD4(+) T(SCM) proliferation in SIV-infected RM correlated inversely with the levels of central memory CD4(+) T cells. In contrast, nonpathogenic SIV infection of SM evidenced preservation of both CD4(+) T(SCM) and CD4(+) central memory T cells, with normal levels of CD4(+) T(SCM) proliferation, and lack of selective depletion of CD4(+)CCR5(+) T(SCM). Importantly, SIV DNA was below the detectable limit in CD4(+) T(SCM) from 8 of 10 SIV-infected SM. We propose that increased proliferation and infection of CD4(+) T(SCM) may contribute to the pathogenesis of SIV infection in RM.

    In response to a new psychological study of persons who believe they have been abducted by space aliens that found that sleep paralysis, a history of being hypnotized, and preoccupation with the paranormal and extraterrestrial were predisposing experiences, I noted that many of the frequently reported particulars of the abduction experience bear more than a passing resemblance to medical-surgical procedures and propose that experience with these may also be contributory. There is the altered state of consciousness, uniformly colored figures with prominent eyes, in a high-tech room under a round bright saucerlike object; there is nakedness, pain and a loss of control while the body's boundaries are being probed; and yet the figures are thought benevolent. No medical-surgical history was apparently taken in the above mentioned study, but psychological laboratory work evaluated false memory formation. I discuss problems in assessing intraoperative awareness and ways in which the medical hypothesis could be elaborated and tested. If physicians are causing this syndrome in a percentage of patients, we should know about it; and persons who feel they have been abducted should be encouraged to inform their surgeons and anesthesiologists without challenging their beliefs.

    1991-01-01

    Many aspects of the superpower relationship now present a new set of challenges and opportunities, including the vital area of arms control. This report addresses one such possibility: the use of robots for the verification of arms control treaties. The central idea of this report is far from commonly-accepted. In fact, it was only encountered once in bibliographic review phase of the project. Nonetheless, the incentive for using robots is simple and coincides with that of industrial applications: to replace or supplement human activity in the performance of tasks for which human participation is unnecessary, undesirable, impossible, too dangerous or too expensive. As in industry, robots should replace workers (in this case, arms control inspectors) only when questions of efficiency, reliability, safety, security and cost-effectiveness have been answered satisfactorily. In writing this report, it is not our purpose to strongly advocate the application of robots in verification. Rather, we wish to explore the significant aspects, pro and con, of applying experience from the field of flexible automation to the complex task of assuring arms control treaty compliance. We want to establish a framework for further discussion of this topic and to define criteria for evaluating future proposals. The authors' expertise is in robots, not arms control. His practical experience has been in developing systems for use in the rehabilitation of severely disabled persons (such as quadriplegics), who can use robots for assistance during activities of everyday living, as well as in vocational applications. This creates a special interest in implementations that, in some way, include a human operator in the control scheme of the robot. As we hope to show in this report, such as interactive systems offer the greatest promise of making a contribution to the challenging problems of treaty verification. 15 refs.

  7. Differential T cell receptor-mediated signaling in naive and memory CD4 T cells.

    Farber, D L; Acuto, O; Bottomly, K

    1997-08-01

    Naive and memory CD4 T cells differ in cell surface phenotype, function, activation requirements, and modes of regulation. To investigate the molecular bases for the dichotomies between naive and memory CD4 T cells and to understand how the T cell receptor (TCR) directs diverse functional outcomes, we investigated proximal signaling events triggered through the TCR/CD3 complex in naive and memory CD4 T cell subsets isolated on the basis of CD45 isoform expression. Naive CD4 T cells signal through TCR/CD3 similar to unseparated CD4 T cells, producing multiple tyrosine-phosphorylated protein species overall and phosphorylating the T cell-specific ZAP-70 tyrosine kinase which is recruited to the CD3zeta subunit of the TCR. Memory CD4 T cells, however, exhibit a unique pattern of signaling through TCR/CD3. Following stimulation through TCR/CD3, memory CD4 T cells produce fewer species of tyrosine-phosphorylated substrates and fail to phosphorylate ZAP-70, yet unphosphorylated ZAP-70 can associate with the TCR/CD3 complex. Moreover, a 26/28-kDa phosphorylated doublet is associated with CD3zeta in resting and activated memory but not in naive CD4 T cells. Despite these differences in the phosphorylation of ZAP-70 and CD3-associated proteins, the ZAP-70-related kinase, p72syk, exhibits similar phosphorylation in naive and memory T cell subsets, suggesting that this kinase could function in place of ZAP-70 in memory CD4 T cells. These results indicate that proximal signals are differentially coupled to the TCR in naive versus memory CD4 T cells, potentially leading to distinct downstream signaling events and ultimately to the diverse functions elicited by these two CD4 T cell subsets.

    We hypothesised that epigenetic regulation of CD4+ T lymphocytes contributes to a shift toward a dysfunctional T cell phenotype which may impact on their ability to clear mycobacterial infection. Combined RNA-seq transcriptomic profiling and Reduced Representation Bisulfite Sequencing identified 193 significantly differentially expressed genes and 760 differentially methylated regions (DMRs), between CD4+ T cells from M. bovis infected and healthy cattle. 196 DMRs were located within 10 kb of annotated genes, including GATA3 and RORC, both of which encode transcription factors that promote TH2 and TH17 T helper cell subsets respectively. Gene-specific DNA methylation and gene expression levels for the TNFRSF4 and Interferon-γ genes were significantly negatively correlated suggesting a regulatory relationship. Pathway analysis of DMRs identified enrichment of genes involved in the anti-proliferative TGF-β signaling pathway and TGFB1 expression was significantly increased in peripheral blood leukocytes from TB-infected cattle. This first analysis of the bovine CD4+ T cell methylome suggests that DNA methylation directly contributes to a distinct gene expression signature in CD4+ T cells from cattle infected with M. bovis. Specific methylation changes proximal to key inflammatory gene loci may be critical to the emergence of a non-protective CD4+ T cell response during mycobacterial infection in cattle. PMID:27507428

    Neuronal computation underlying detection of visual motion has been studied for more than a half-century. In Drosophila, direction-selective T4/T5 neurons show supralinear signal amplification in response to stimuli moving in their preferred direction, in agreement with the prediction made by the Hassenstein-Reichardt detector. Nevertheless, the molecular mechanism explaining how the Hassenstein-Reichardt model is implemented in T4/T5 cells has not been identified yet. In the present study, we utilized cell type-specific transcriptome profiling with RNA-seq to obtain a complete gene expression profile of T4/T5 neurons. We analyzed the expression of genes that affect neuronal computational properties and can underlie the molecular implementation of the core features of the Hassenstein-Reichardt model to the dendrites of T4/T5 neurons. Furthermore, we used the acquired RNA-seq data to examine the neurotransmitter system used by T4/T5 neurons. Surprisingly, we observed co-expression of the cholinergic markers and the vesicular GABA transporter in T4/T5 neurons. We verified the previously undetected expression of vesicular GABA transporter in T4/T5 cells using VGAT-LexA knock-in line. The provided gene expression dataset can serve as a useful source for studying the properties of direction-selective T4/T5 neurons on the molecular level. PMID:27684367

    CD4(+) T cells in female MRL+/+ mice exposed to solvent and water pollutant trichloroethylene (TCE) skew toward effector/memory CD4(+) T cells, and demonstrate seemingly non-monotonic alterations in IFN-γ production. In the current study we examined the mechanism for this immunotoxicity using effector/memory and naïve CD4(+) T cells isolated every 6 weeks during a 40 week exposure to TCE (0.5mg/ml in drinking water). A time-dependent effect of TCE exposure on both Ifng gene expression and IFN-γ protein production was observed in effector/memory CD4(+) T cells, with an increase after 22 weeks of exposure and a decrease after 40 weeks of exposure. No such effect of TCE was observed in naïve CD4(+) T cells. A cumulative increase in DNA methylation in the CpG sites of the promoter of the Ifng gene was observed in effector/memory, but not naïve, CD4(+) T cells over time. Also unique to the Ifng promoter was an increase in methylation variance in effector/memory compared to naïve CD4(+) T cells. Taken together, the CpG sites of the Ifng promoter in effector/memory CD4(+) T cells were especially sensitive to the effects of TCE exposure, which may help explain the regulatory effect of the chemical on this gene.

  13. Selective culling of high avidity antigen-specific CD4+ T cells after virulent Salmonella infection.

    Typhoid fever is a persistent infection caused by host-adapted Salmonella strains adept at circumventing immune-mediated host defences. Given the importance of T cells in protection, the culling of activated CD4+ T cells after primary infection has been proposed as a potential immune evasion strategy used by this pathogen. We demonstrate that the purging of activated antigen-specific CD4+ T cells after virulent Salmonella infection requires SPI-2 encoded virulence determinants, and is not restricted only to cells with specificity to Salmonella-expressed antigens, but extends to CD4+ T cells primed to expand by co-infection with recombinant Listeria monocytogenes. Unexpectedly, however, the loss of activated CD4+ T cells during Salmonella infection demonstrated using a monoclonal population of adoptively transferred CD4+ T cells was not reproduced among the endogenous repertoire of antigen-specific CD4+ T cells identified with MHC class II tetramer. Analysis of T-cell receptor variable segment usage revealed the selective loss and reciprocal enrichment of defined CD4+ T-cell subsets after Salmonella co-infection that is associated with the purging of antigen-specific cells with the highest intensity of tetramer staining. Hence, virulent Salmonella triggers the selective culling of high avidity activated CD4+ T-cell subsets, which re-shapes the repertoire of antigen-specific T cells that persist later after infection.

  16. The search for alien life

    NASA Astrophysics Data System (ADS)

    Meyer, M.

    Life on Earth relies exclusively on the complex coordination among DNA, RNA, proteins, and an encompassing cell membrane. This level of complexity has been amenable to new molecular techniques with extreme specificity and sensitivity, enabling spectacular advances in cell biology and microbial ecology. Armed with molecular techniques, the last few decades of research have revealed the surprising extent of life on our own planet, expanding the habitable range of salinity, pressure, temperature, and radiation of our world. Given the relatively recent discoveries about life on Earth, how then can we expect to look for alien life that may use completely different sets of molecules for structure and activity? Astrobiology has taken on the challenge of developing the intellectual basis, target identification, instrument capabilities, and operational procedures for the search for life elsewhere. The research aims to develop general principles of how life maintains itself, how life interacts with its environment, and how the signatures of life may be preserved and recognized. The approach has been to move from the laboratory, to the environment, to robotic exploration of planetary analogs. To date, generic evidence for life can be perceived through life's creation and utilization of disequilibria, multiple uses of a relatively few sets of molecules, a preference for chiral compounds, and a predilection for lighter isotopes. It is through application of life detection instrumentation in environmental extremes that we hope to develop a catalogue of generic biosignatures, robust instrumentation capable of revealing the unexpected, and effective exploration strategies for robotic platforms in the search for signs of life. In 2009, Mars Science Laboratory and ExoMars may be the first beneficiaries of this approach.

  17. Forensic Seismology and the Comprehensive Nuclear-Test-Ban Treaty

    2009-05-01

    One application of forensic seismology is to help verify compliance with the Comprehensive Nuclear-Test-Ban Treaty. One of the challenges facing the forensic seismologist is to discriminate between the many thousands of earthquakes of potential interest each year and potential Treaty violations (underground explosions). There are four main methods: (a) ratio of body- to surface-wave magnitudes, (b) ratio of high-frequency P to S energy, (c) model-based methods, and (d) source depth. Methods (a) and (b) have an empirical basis. The weakness of methods (a)-(c) is the lack of an equivalent elastic source for an underground explosion fired in the range of geological media found around the world. Reliable routine source-depth determination has proved difficult. However, experience gained in the past decade at identifying suspicious seismic sources suggests that although no single method works all of the time, intelligent and original application of complementary methods is usually sufficient to satisfactorily identify the source in question.

  19. Using effect size benchmarks to assess when alien impacts are actually alien.

    Alien predators have on average twice the impact on native prey populations than do native predators, and are a severe threat to wildlife globally. Manipulation experiments can be used to quantify the impact of an alien predator on its prey population/s, but unless the results are compared to benchmarks, it is unclear whether this impact is indeed greater than that of a native predator. Here we use the Australian garden skink Lampropholis delicata and alien black rat Rattus rattus to test if black rats are an additive source of predation for the skink, and to judge whether the effect size of rat-impact on the skink represents that of an alien or native predator. We used replicated experiments to exclude black rats at local and landscape scales to test how rats affect skink activity and trapping frequency. Both manipulations had positive effects on skinks, however, the population-level effect size was lower than that described for alien predators but similar to that expected for native predators. We suggest that Australian skinks may respond appropriately to predatory alien rats because they coevolved with endemic Rattus species. This adds novel insights into the varying levels of impact that alien predators have on native prey.

    AIM To investigate the abundance and potential functions of LAP+CD4+ T cells in colorectal cancer (CRC). METHODS Proportions of LAP+CD4+ T cells were examined in peripheral blood and tumor/paratumor tissues of CRC patients and healthy controls using flow cytometry. Expression of phenotypic markers such as forkhead box (Fox)p3, cytotoxic T-lymphocyte-associated protein (CTLA)-4, chemokine CC receptor (CCR)4 and CCR5 was measured using flow cytometry. LAP-CD4+ and LAP+CD4+ T cells were isolated using a magnetic cell-sorting system and cell purity was analyzed by flow cytometry. Real-time quantitative polymerase chain reaction was used to measure expression of cytokines interleukin (IL)-10 and transforming growth factor (TGF)-β. RESULTS The proportion of LAP+CD4+ T cells was significantly higher in peripheral blood from patients (9.44% ± 3.18%) than healthy controls (1.49% ± 1.00%, P < 0.001). Among patients, the proportion of LAP+CD4+ T cells was significantly higher in tumor tissues (11.76% ± 3.74%) compared with paratumor tissues (3.87% ± 1.64%, P < 0.001). We also observed positive correlations between the proportion of LAP+CD4+ T cells and TNM stage (P < 0.001), distant metastasis (P < 0.001) and serum level of carcinoembryonic antigen (P < 0.05). Magnetic-activated cell sorting gave an overall enrichment of LAP+CD4+ T cells (95.02% ± 2.87%), which was similar for LAP-CD4+ T cells (94.75% ± 2.76%). In contrast to LAP-CD4+ T cells, LAP+CD4+ T cells showed lower Foxp3 expression but significantly higher levels of CTLA-4, CCR4 and CCR5 (P < 0.01). LAP+CD4+ T cells expressed significantly larger amounts of IL-10 and TGF-β but lower levels of IL-2, IL-4, IL-17 and interferon-γ, compared with LAP-CD4+ T cells. CONCLUSION LAP+CD4+ T cells accumulated in the tumor microenvironment of CRC patients and were involved in immune evasion mediated by IL-10 and TGF-β. PMID:28210081

  2. Itk Signals Promote Neuroinflammation by Regulating CD4+ T-Cell Activation and Trafficking

    PubMed Central

    Kannan, Arun K.; Kim, Do-Geun

    2015-01-01

    Here we demonstrate that interleukin-2-inducible T-cell kinase (Itk) signaling in cluster of differentiation 4-positive (CD4+) T cells promotes experimental autoimmune encephalomyelitis (EAE), the animal model of multiple sclerosis (MS). We show that Itk−/− mice exhibit reduced disease severity, and transfer of Itk−/− CD4+ T cells into T cell-deficient recipients results in lower disease severity. We observed a significant reduction of CD4+ T cells in the CNS of Itk−/− mice or recipients of Itk−/− CD4+ T cells during EAE, which is consistent with attenuated disease. Itk−/− CD4+ T cells exhibit defective response to myelin antigen stimulation attributable to displacement of filamentous actin from the CD4+ coreceptor. This results in inadequate transmigration of Itk−/− CD4+ T cells into the CNS and across brain endothelial barriers in vitro. Finally, Itk−/− CD4+ T cells show significant reduction in production of T-helper 1 (Th1) and Th17 cytokines and exhibit skewed T effector/T regulatory cell ratios. These results indicate that signaling by Itk promotes autoimmunity and CNS inflammation, suggesting that it may be a viable target for treatment of MS. PMID:25568116

    DJ-1/Park7 is a redox-sensitive chaperone protein counteracting oxidation and presumably contributing to the control of oxidative stress responses and thus inflammation. DJ-1 gene deletion exacerbates the progression of Parkinson's disease presumably by augmenting oxidative stress. Formation of reactive oxygen species (ROS) is paralleled by activation of the Na(+) /H(+) exchanger 1 (NHE1). ROS formation in CD4(+) T cells plays a decisive role in regulating inflammatory responses. In the present study we explored whether DJ-1 is expressed in CD4(+) T cells and affects ROS production as well as NHE1 in those cells. To this end, DJ-1 and NHE1 transcript and protein levels were quantified by qRT-PCR and Western blotting respectively, intracellular pH (pHi) utilizing bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein (BCECF) fluorescence, NHE activity from realkalinization after an ammonium pulse, and ROS production utilizing 2',7' -dichlorofluorescin diacetate (DCFDA) fluorescence. As a result DJ-1 was expressed in CD4(+) T cells. ROS formation, NHE1 transcript levels, NHE1 protein, and NHE activity were higher in CD4(+) T cells from DJ-1 deficient mice than in CD4(+) T cells from wild type mice. Antioxidant N-acetyl-cysteine (NAC) and protein tyrosine kinase (PTK) inhibitor staurosporine decreased the NHE activity in DJ-1 deficient CD4(+) T cells, and blunted the difference between DJ-1(-/-) and DJ-1(+/+) CD4(+) T cells, an observation pointing to a role of ROS in the up-regulation of NHE1 in DJ-1(-/-) CD4(+) T cells. In conclusion, DJ-1 is a powerful regulator of ROS production as well as NHE1 expression and activity in CD4(+) T cells. This article is protected by copyright. All rights reserved.

    2009-04-01

    Since 1964, the Columbia River Treaty has provided significant benefits to the United States and Canada through coordinated river management by the two countries. It remains the standard against which other international water coordination agreements around the world are compared. When the Treaty was negotiated, its goals were to provide significant flood control and power generation benefits to both countries. However, the Treaty contains two provisions that may significantly change these benefits as early as the year 2024. First, in 2024 the 60 years of purchased flood control space in Canadian Treaty projects expires. Instead of a coordinated and managed plan to regulate both Canadian and U.S. projects for flood control, the Treaty calls for a shift to a Canadian operation under which the United States can call upon Canada for flood control assistance. The United States can request this “called upon” assistance as needed but only to the extent necessary to meet forecast flood control needs in the United States that cannot adequately be met by U.S. projects. When called upon is requested, the United States will then have to pay Canada for its operational costs and any economic losses resulting from the called upon flood control operation. Second, while the Treaty has no specified end date, it does allow either Canada or the United States the option to terminate most of the provisions of the Treaty on or after Sept. 16, 2024, with a minimum of 10 years advance written notice. Thus, the year 2024 is the first year a notice of termination would take effect assuming written notice of termination is given by the Canadian or U.S. governments by 2014. Unless the Treaty is terminated or the federal governments elect to modify the Treaty, its provisions continue indefinitely, except for the changes in flood control discussed above. Given the significance of both of these provisions, it is important that the parties to the Treaty understand the implications for post

    We assessed what impact can be expected from global health treaties on the basis of 90 quantitative evaluations of existing treaties on trade, finance, human rights, conflict, and the environment. It appears treaties consistently succeed in shaping economic matters and consistently fail in achieving social progress. There are at least 3 differences between these domains that point to design characteristics that new global health treaties can incorporate to achieve positive impact: (1) incentives for those with power to act on them; (2) institutions designed to bring edicts into effect; and (3) interests advocating their negotiation, adoption, ratification, and domestic implementation. Experimental and quasiexperimental evaluations of treaties would provide more information about what can be expected from this type of global intervention. PMID:25393196

    2012-07-12

    In recent years, there is growing interest in formal negotiations on non-strategic or tactical nuclear weapons. With the negotiations of New START, there has been much speculation that a tactical nuclear weapons treaty should be included in the follow on to New START. This paper examines the current policy environment related to tactical weapons and some of the issues surrounding the definition of tactical nuclear weapons. We then map out the steps that would need to be taken in order to begin discussions on a tactical nuclear weapons treaty. These steps will review the potential role of the IAEA in verification of a tactical nuclear weapons treaty. Specifically, does IAEA involvement in various arms control treaties serve as a useful roadmap on how to overcome some of the issues pertaining to a tactical nuclear weapons treaty?

    Monitoring for xenon radionuclides which are produced in a nuclear detonation can provide a strong deterrent to the violation of a Comprehensive nuclear Test Ban Treaty (CTBT). There are 18 known radioactive xenon isotopes produced in nuclear fission with half-lives ranging from less than one second to 11.9 days. However, only four of these remain in significant amounts more than a day after a detonation. In order for radioxenon monitoring to be practical, it was necessary to develop an automated measurement system which could operate unattended for periods of months, measure the entire spectrum of radioxenons, and provide hundreds of times better sensitivities than current laboratory procedures. This capability was developed at the US Department of Energy`s Pacific Northwest National Laboratory based on rapid separation of atmospheric xenon coupled with a unique high sensitivity measurement device for the radioxenons. A fieldable prototype analyzer is scheduled for testing in August 1996 with commercial availability planned by 1998.

    Parental alienation occurs in divorces when one parent indoctrinates the child to dislike, fear, and avoid contact with the other parent. Mental health professionals who treat children and adolescents are likely to encounter victims of parental alienation in clinical practice, and it is important to identify and treat these youngsters earlier, when the condition is mild, rather than later, when the parental alienation is almost intractable. This article presents an overview of the treatment of parental alienation, which is called reunification therapy. All the parties involved in the case have a role in the prevention and treatment of parental alienation.

    2014-01-01

    Background Alien hand syndrome (AHS) is a disorder of involuntary, yet purposeful, hand movements that may be accompanied by agnosia, aphasia, weakness, or sensory loss. We herein review the most reported cases, current understanding of the pathophysiology, and treatments. Methods We performed a PubMed search in July of 2014 using the phrases “alien hand syndrome,” “alien hand syndrome pathophysiology,” “alien hand syndrome treatment,” and “anarchic hand syndrome.” The search yielded 141 papers (reviews, case reports, case series, and clinical studies), of which we reviewed 109. Non-English reports without English abstracts were excluded. Results Accumulating evidence indicates that there are three AHS variants: frontal, callosal, and posterior. Patients may demonstrate symptoms of multiple types; there is a lack of correlation between phenomenology and neuroimaging findings. Most pathologic and functional imaging studies suggest network disruption causing loss of inhibition as the likely cause. Successful interventions include botulinum toxin injections, clonazepam, visuospatial coaching techniques, distracting the affected hand, and cognitive behavioral therapy. Discussion The available literature suggests that overlap between AHS subtypes is common. The evidence for effective treatments remains anecdotal, and, given the rarity of AHS, the possibility of performing randomized, placebo-controlled trials seems unlikely. As with many other interventions for movement disorders, identifying the specific functional impairments caused by AHS may provide the best guidance towards individualized supportive care.

    Interleukin (IL)-22 produced by innate lymphoid cells (ILCs) and CD4+ T cells plays an important role in host defence and mucosal homeostasis, thus it is important to investigate the mechanisms that regulate IL-22 production. We investigated the regulation IL-22 production by CD4+ T cells. Here we show that IL-21 triggers IL-22, but not IL-17 production by CD4+ T cells. STAT3, activated by IL-21, controls the epigenetic status of the il22 promoter and its interaction with the aryl hydrocarbon receptor (AhR). Moreover, IL-21 and AhR signalling in T cells control IL-22 production and the development of dextran sodium sulphate-induced colitis in ILC-deficient mice. Thus, we have identified IL-21 as an inducer of IL-22 production in CD4+ T cells in vitro and in vivo.

    2017-01-01

    Pathogen-specific polyfunctional T cell responses have been associated with favorable clinical outcomes, but it is not known whether molecular differences exist between polyfunctional and monofunctional cytokine-producing T cells. Here, we report that polyfunctional CD4+ T cells induced during Plasmodium falciparum (P. falciparum) blood-stage infection in humans have a unique transcriptomic profile compared with IFN-γ monofunctional CD4+ T cells and, thus, are molecularly distinct. The 14-gene signature revealed in P. falciparum–reactive polyfunctional T cells is associated with cytokine signaling and lymphocyte chemotaxis, and systems biology analysis identified IL-27 as an upstream regulator of the polyfunctional gene signature. Importantly, the polyfunctional gene signature is largely conserved in Influenza-reactive polyfunctional CD4+ T cells, suggesting that polyfunctional T cells have core characteristics independent of pathogen specificity. This study provides the first evidence to our knowledge that consistent molecular differences exist between polyfunctional and monofunctional CD4+ T cells. PMID:28194431

    CD4+ T cells have been and are still largely regarded as the orchestrators of immune responses, being able to differentiate into distinct T helper cell populations based on differentiation signals, transcription factor expression, cytokine secretion, and specific functions. Nonetheless, a growing body of evidence indicates that CD4+ T cells can also exert a direct effector activity, which depends on intrinsic cytotoxic properties acquired and carried out along with the evolution of several pathogenic infections. The relevant role of CD4+ T cell lytic features in the control of such infectious conditions also leads to their exploitation as a new immunotherapeutic approach. This review aims at summarizing currently available data about functional and therapeutic relevance of cytotoxic CD4+ T cells in the context of viral infections and virus-driven tumors.

    Reservoirs of infectious HIV-1 persist despite years of combination antiretroviral therapy and make curing HIV-1 infections a major challenge. Most of the proviral DNA resides in CD4(+)T cells. Some of these CD4(+)T cells are clonally expanded; most of the proviruses are defective. It is not known if any of the clonally expanded cells carry replication-competent proviruses. We report that a highly expanded CD4(+) T-cell clone contains an intact provirus. The highly expanded clone produced infectious virus that was detected as persistent plasma viremia during cART in an HIV-1-infected patient who had squamous cell cancer. Cells containing the intact provirus were widely distributed and significantly enriched in cancer metastases. These results show that clonally expanded CD4(+)T cells can be a reservoir of infectious HIV-1.

    IL-7 is known to be vital for T cell homeostasis but has previously been presumed to be dispensable for TCR-induced activation. Here, we show that IL-7 is critical for the initial activation of CD4+ T cells in that it provides some of the necessary early signaling components, such as activated STAT5 and Akt. Accordingly, short-term in vivo IL-7Rα blockade inhibited the activation and expansion of autoantigen-specific CD4+ T cells and, when used to treat experimental autoimmune encephalomyelitis (EAE), prevented and ameliorated disease. Our studies demonstrate that IL-7 signaling is a prerequisite for optimal CD4+ T cell activation and that IL-7R antagonism may be effective in treating CD4+ T cell-mediated neuroinflammation and other autoimmune inflammatory conditions.

    Perez-Mazliah, Damian; Langhorne, Jean

    2015-01-01

    CD4+ T-cells have been shown to play a central role in immune control of infection with Plasmodium parasites. At the erythrocytic stage of infection, IFN-γ production by CD4+ T-cells and CD4+ T-cell help for the B-cell response are required for control and elimination of infected red blood cells. CD4+ T-cells are also important for controlling Plasmodium pre-erythrocytic stages through the activation of parasite-specific CD8+ T-cells. However, excessive inflammatory responses triggered by the infection have been shown to drive pathology. Early classical experiments demonstrated a biphasic CD4+ T-cell response against erythrocytic stages in mice, in which T helper (Th)1 and antibody-helper CD4+ T-cells appear sequentially during a primary infection. While IFN-γ-producing Th1 cells do play a role in controlling acute infections, and they contribute to acute erythrocytic-stage pathology, it became apparent that a classical Th2 response producing IL-4 is not a critical feature of the CD4+ T-cell response during the chronic phase of infection. Rather, effective CD4+ T-cell help for B-cells, which can occur in the absence of IL-4, is required to control chronic parasitemia. IL-10, important to counterbalance inflammation and associated with protection from inflammatory-mediated severe malaria in both humans and experimental models, was originally considered be produced by CD4+ Th2 cells during infection. We review the interpretations of CD4+ T-cell responses during Plasmodium infection, proposed under the original Th1/Th2 paradigm, in light of more recent advances, including the identification of multifunctional T-cells such as Th1 cells co-expressing IFN-γ and IL-10, the identification of follicular helper T-cells (Tfh) as the predominant CD4+ T helper subset for B-cells, and the recognition of inherent plasticity in the fates of different CD4+ T-cells.

    Background An effective adaptive immune response requires activation of specific CD4 T cells. The capacity of B cells to activate CD4 T cells in human cutaneous leishmaniasis caused by Leishmania (Viannia) has not been evaluated. Methods CD4 T cell activation by B cells of cutaneous leishmaniasis patients was evaluated by culture of PBMCs or purified B cells and CD4 T cells with Leishmania panamensis antigens. CD4 T cell and B cell activation markers were evaluated by flow cytometry and 13 cytokines were measured in supernatants with a bead-based capture assay. The effect of Leishmania antigens on BCR-mediated endocytosis of ovalbumin was evaluated in the Ramos human B cell line by targeting the antigen with anti-IgM-biotin and anti-biotin-ovalbumin-FITC. Results Culture of PBMCs from cutaneous leishmaniasis patients with Leishmania antigens resulted in upregulation of the activation markers CD25 and CD69 as well as increased frequency of CD25hiCD127- cells among CD4 T cells. Concomitantly, B cells upregulated the costimulatory molecule CD86. These changes were not observed in PBMCs from healthy subjects, indicating participation of Leishmania-specific lymphocytes expanded in vivo. Purified B cells from these patients, when interacting with purified CD4 T cells and Leishmania antigens, were capable of inducing significant increases in CD25 and CD69 expression and CD25hiCD127- frequency in CD4 T cells. These changes were associated with upregulation of CD86 in B cells. Comparison of changes in CD4 T cell activation parameters between PBMC and B cell/CD4 T cell cultures showed no statistically significant differences; further, significant secretion of IFN-γ, TNF-α, IL-6 and IL-13 was induced in both types of cultures. Additionally, culture with Leishmania antigens enhanced BCR-mediated endocytosis of ovalbumin in Ramos human B cells.

    Background CD4+ T cell help is critical in maintaining antiviral immune responses and such help has been shown to be sustained in acute resolving hepatitis C. In contrast, in evolving chronic hepatitis C CD4+ T cell helper responses appear to be absent or short-lived, using functional assays. Methodology/Principal Findings Here we used a novel HLA-DR1 tetramer containing a highly targeted CD4+ T cell epitope from the hepatitis C virus non-structural protein 4 to track number and phenotype of hepatitis C virus specific CD4+ T cells in a cohort of seven HLA-DR1 positive patients with acute hepatitis C in comparison to patients with chronic or resolved hepatitis C. We observed peptide-specific T cells in all seven patients with acute hepatitis C regardless of outcome at frequencies up to 0.65% of CD4+ T cells. Among patients who transiently controlled virus replication we observed loss of function, and/or physical deletion of tetramer+ CD4+ T cells before viral recrudescence. In some patients with chronic hepatitis C very low numbers of tetramer+ cells were detectable in peripheral blood, compared to robust responses detected in spontaneous resolvers. Importantly we did not observe escape mutations in this key CD4+ T cell epitope in patients with evolving chronic hepatitis C. Conclusions/Significance During acute hepatitis C a CD4+ T cell response against this epitope is readily induced in most, if not all, HLA-DR1+ patients. This antiviral T cell population becomes functionally impaired or is deleted early in the course of disease in those where viremia persists. PMID:17653276

  15. A simple theoretical framework for understanding heterogeneous differentiation of CD4+ T cells

    PubMed Central

    2012-01-01

    Background CD4+ T cells have several subsets of functional phenotypes, which play critical yet diverse roles in the immune system. Pathogen-driven differentiation of these subsets of cells is often heterogeneous in terms of the induced phenotypic diversity. In vitro recapitulation of heterogeneous differentiation under homogeneous experimental conditions indicates some highly regulated mechanisms by which multiple phenotypes of CD4+ T cells can be generated from a single population of naïve CD4+ T cells. Therefore, conceptual understanding of induced heterogeneous differentiation will shed light on the mechanisms controlling the response of populations of CD4+ T cells under physiological conditions. Results We present a simple theoretical framework to show how heterogeneous differentiation in a two-master-regulator paradigm can be governed by a signaling network motif common to all subsets of CD4+ T cells. With this motif, a population of naïve CD4+ T cells can integrate the signals from their environment to generate a functionally diverse population with robust commitment of individual cells. Notably, two positive feedback loops in this network motif govern three bistable switches, which in turn, give rise to three types of heterogeneous differentiated states, depending upon particular combinations of input signals. We provide three prototype models illustrating how to use this framework to explain experimental observations and make specific testable predictions. Conclusions The process in which several types of T helper cells are generated simultaneously to mount complex immune responses upon pathogenic challenges can be highly regulated, and a simple signaling network motif can be responsible for generating all possible types of heterogeneous populations with respect to a pair of master regulators controlling CD4+ T cell differentiation. The framework provides a mathematical basis for understanding the decision-making mechanisms of CD4+ T cells, and it can be

    Global transcriptome studies can help pinpoint key cellular pathways exploited by viruses to replicate and cause pathogenesis. Previous data showed that laboratory-adapted HIV-1 triggers significant gene expression changes in CD4+ T cell lines and mitogen-activated CD4+ T cells from peripheral blood. However, HIV-1 primarily targets mucosal compartments during acute infection in vivo. Moreover, early HIV-1 infection causes extensive depletion of CD4+ T cells in the gastrointestinal tract that herald persistent inflammation due to the translocation of enteric microbes to the systemic circulation. Here, we profiled the transcriptome of primary intestinal CD4+ T cells infected ex vivo with transmitted/founder (TF) HIV-1. Infections were performed in the presence or absence of Prevotella stercorea, a gut microbe enriched in the mucosa of HIV-1-infected individuals that enhanced both TF HIV-1 replication and CD4+ T cell death ex vivo. In the absence of bacteria, HIV-1 triggered a cellular shutdown response involving the downregulation of HIV-1 reactome genes, while perturbing genes linked to OX40, PPAR and FOXO3 signaling. However, in the presence of bacteria, HIV-1 did not perturb these gene sets or pathways. Instead, HIV-1 enhanced granzyme expression and Th17 cell function, inhibited G1/S cell cycle checkpoint genes and triggered downstream cell death pathways in microbe-exposed gut CD4+ T cells. To gain insights on these differential effects, we profiled the gene expression landscape of HIV-1-uninfected gut CD4+ T cells exposed to bacteria. Microbial exposure upregulated genes involved in cellular proliferation, MAPK activation, Th17 cell differentiation and type I interferon signaling. Our findings reveal that microbial exposure influenced how HIV-1 altered the gut CD4+ T cell transcriptome, with potential consequences for HIV-1 susceptibility, cell survival and inflammation. The HIV-1- and microbe-altered pathways unraveled here may serve as a molecular blueprint

    The T cell lineage is commonly divided into CD4-expressing helper T cells that polarize immune responses through cytokine secretion and CD8-expressing cytotoxic T cells that eliminate infected target cells by virtue of the release of cytotoxic molecules. Recently, a population of CD4+ T cells that conforms to the phenotype of cytotoxic CD8+ T cells has received increased recognition. These cytotoxic CD4+ T cells display constitutive expression of granzyme B and perforin at the protein level and mediate HLA class II-dependent killing of target cells. In humans, this cytotoxic profile is found within the human cytomegalovirus (hCMV)-specific, but not within the influenza- or Epstein–Barr virus-specific CD4+ T cell populations, suggesting that, in particular, hCMV infection induces the formation of cytotoxic CD4+ T cells. We have previously described that the transcription factor Homolog of Blimp-1 in T cells (Hobit) is specifically upregulated in CD45RA+ effector CD8+ T cells that arise after hCMV infection. Here, we describe the expression pattern of Hobit in human CD4+ T cells. We found Hobit expression in cytotoxic CD4+ T cells and accumulation of Hobit+ CD4+ T cells after primary hCMV infection. The Hobit+ CD4+ T cells displayed highly overlapping characteristics with Hobit+ CD8+ T cells, including the expression of cytotoxic molecules, T-bet, and CX3CR1. Interestingly, γδ+ T cells that arise after hCMV infection also upregulate Hobit expression and display a similar effector phenotype as cytotoxic CD4+ and CD8+ T cells. These findings suggest a shared differentiation pathway in CD4+, CD8+, and γδ+ T cells that may involve Hobit-driven acquisition of long-lived cytotoxic effector function. PMID:28392788

    Early immunological events during acute HIV infection are thought to fundamentally influence long-term disease outcome. Whereas the contribution of HIV-specific CD8 T cell responses to early viral control is well established, the role of HIV-specific CD4 T cell responses in the control of viral replication following acute infection is unknown. A growing body of evidence suggests that CD4 T cells - besides their helper function - have the capacity to directly recognize and kill virally infected cells. In a longitudinal study of a cohort of individuals acutely infected with HIV, we observed that subjects able to spontaneously control HIV replication in the absence of antiretroviral therapy showed a significant expansion of HIV-specific CD4 T cell responses—but not CD8 T cell responses–compared to subjects who progressed to a high viral set point (p=0.038). Strikingly, this expansion occurred prior to differences in viral load or CD4 T cell count and was characterized by robust cytolytic activity and expression of a distinct profile of perforin and granzymes at the earliest time point. Kaplan-Meier analysis revealed that the emergence of Granzyme A+ HIV-specific CD4 T cell responses at baseline was highly predictive of slower disease progression and clinical outcome (average days to CD4 T cell count <350/μl was 575 versus 306, p=0.001). These data demonstrate that HIV-specific CD4 T cell responses can be used during the earliest phase of HIV infection as an immunological predictor of subsequent viral set point and disease outcome. Moreover, these data suggest that expansion of Granzyme A+ HIV-specific cytolytic CD4 T cell responses early during acute HIV infection contributes substantially to the control of viral replication.
