Venecuba: An Analysis of Cuban Influence in Venezuela and its Support for the Bolívarian Revolution

This research examines the profound Cuban-Venezuelan relationship and the immense influence Cuba has in Venezuelan politics and society. By looking at Cuban involvement in both the Venezuelan government’s social programs and the Venezuelan military, this study explores the degree to which Cuba can be held responsible for the longevity of “Chavismo” in Venezuela. In many ways, the implementation of Hugo Chávez’s “Bolívarian Revolution” and the survival of Nicolás Maduro’s government rest largely in the hands of the Cubans

The 20th Anniversary Meeting of the Rocky Mountain Virology Association

Due to the COVID-19 pandemic and multiple devastating forest fires, the 2020 meeting of the Rocky Mountain Virology Association was held virtually. The three-day gathering featured talks describing recent advances in virology and prion research. The keynote presentation described the measles virus paradox of immune suppression and life-long immunity. Special invited speakers presented information concerning visualizing antiviral effector cell biology in mucosal tissues, uncovering the T-cell tropism of Epstein-Barr virus type 2, a history and current survey of coronavirus spike proteins, a summary of Zika virus vaccination and immunity, the innate immune response to flavivirus infections, a discussion concerning prion disease as it relates to multiple system atrophy, and clues for discussing virology with the non-virologist. On behalf of the Rocky Mountain Virology Association, this report summarizes selected presentations

The relationships between internal and external threat and right-wing attitudes: A three-wave longitudinal study

The interplay between threat and right-wing attitudes has received much research attention, but its longitudinal relationship has hardly been investigated. In this study, we investigated the longitudinal relationships between internal and external threat and right-wing attitudes using a cross-lagged design at three different time points in a large nationally representative sample (N = 800). We found evidence for bidirectional relationships. Higher levels of external threat were related to higher levels of Right-Wing Authoritarianism and to both the egalitarianism and dominance dimensions of Social Dominance Orientation at a later point in time. Conversely, higher levels of RWA were also related to increased perception of external threat later in time. Internal threat did not yield significant direct or indirect longitudinal relationships with right-wing attitudes. Theoretical and practical implications of these longitudinal effects are discussed

Translational Research and Medicine at NASA: From Earth to Space and Back Again

The Space Environment provides many challenges to the human physiology and therefore to extended habitation and exploration. Translational research and medical strategies are meeting these challenges by combining Earth based medical solutions with innovative and developmental engineering approaches. Translational methodologies are current applied to spaceflight related dysregulations in the areas of: (1) cardiovascular fluid shifts, intracranial hypertension and neuro-ocular impairment 2) immune insufficiency and suppression/viral re-expression, 3) bone loss and fragility (osteopenia/osteoporosis) and muscle wasting, and finally 4) radiation sensitivity and advanced ageing. Over 40 years of research into these areas have met with limited success due to lack of tools and basic understanding of central issues that cause physiologic maladaptaion and distrupt homeostatis. I will discuss the effects of living in space (reduced gravity, increased radiation and varying atmospheric conditions [EVA]) during long-duration, exploration-class missions and how translational research has benefited not only space exploration but also Earth based medicine. Modern tools such as telemedicine advances in genomics, proteomics, and metabolomics (Omicssciences) has helped address syndromes, at the systemic level by enlisting a global approach to assessing spaceflight physiology and to develop countermeasures thereby permitting our experience in space to be translated to the Earth's medical community

Экспериментальные исследования процессов миграции водорода в титане электрическими методами

В работе исследован процесс диффузионного переноса водорода в титановой пластине вихретоковым методом по глубине образца. Интегральный перенос изучен методом измерения термоэдс. Разработана установка для исследования процесса миграции водорода в сплаве титана при его насыщении электролитически в присутствии тиокарбомида. Исследована роль тиокарбамида. Проведено измерение вихревых токов по координате и во времени на различных частотах, что позволяет исследовать процессы миграции на разных глубинах образца. Исследован процесс миграции водорода в титановом сплаве методом измерения термоэдс.The process of diffusion transport of hydrogen in a titanium plate by the eddy current method has been investigated in the depth of samples. The integral transport has been studied by measuring thermoelectric powers. An installation was developed for studying the process of hydrogen shift in titanium alloys when electrolytically saturated with thiocarbomide. The role of thiourea is investigated. The measurement of eddy currents in coordinate and time is carried out at different frequencies, which makes it is possible to study the shift processes at different depths of the sample. The process of hydrogen shift in titanium alloys is studied by measuring thermoelectric powers

Varicella Zoster Virus in Saliva of Patients With Herpes Zoster

Background. VZV DNA is present in saliva of healthy astronauts and patients with Ramsay Hunt syndrome (geniculate zoster). We hypothesized that a prospective analysis of patients with zoster would detect VZV in saliva independent of zoster location. Methods. We treated 54 patients with valacyclovir. On the first treatment day, 7- and 14-days later, pain was scored and saliva examined for VZV DNA. Saliva from six subjects with chronic pain and 14 healthy subjects was similarly studied. Results. Follow-up data was available for 50/54 patients. Pain decreased in 43/50 (86 percent), disappeared in 37 (74 percent), recurred after disappearing in three (6 percent) and increased in four (8 percent). VZV DNA was found in every patient the day treatment was started, decreased in 47/50 (94 percent), transiently increased in three (6 percent) before decreasing, increased in two (4 percent) and disappeared in 41 (82 percent). There was a positive correlation between the presence of VZV DNA and pain, as well as between the VZV DNA copy number and pain (P<0.0005). Saliva of two patients was cultured, and infectious VZV was isolated from one. VZV DNA was present in one patient before rash and in four patients after pain resolved, and not in any control subjects. Conclusion. VZV DNA is present in saliva of zoster patients

Human rights education in Japan: An historical account, characteristics and suggestions for a better-balanced approach

Although human rights are often expressed as universal tenets, the concept was conceived in a particular socio-political and historical context. Conceptualisations and practice of human rights vary across societies, and face numerous challenges. After providing an historical account of the conceptualisation of human rights in Japanese society, this paper examines human rights education in Japan, focusing on implementation of the United Nations Decade for Human Rights Education. Whilst the Decade’s Action Plan advocates a comprehensive approach, Japanese human rights education focuses far less attention on imparting knowledge and developing learners’ attitudes, placing strong emphasis on aspects of responsibility and harmonious human relations understood in the historical context of Japanese moral education. Pedagogical proposals are made to promote a comprehensive approach, including focus on the role of empowering learners, enabling them to protect themselves by invoking human rights

Varicella zoster virus infection of highly pure terminally differentiated human neurons

In vitro analyses of varicella zoster virus (VZV) reactivation from latency in human ganglia have been hampered by the inability to isolate virus by explantation or cocultivation techniques. Furthermore, attempts to study interaction of VZV with neurons in experimentally infected ganglion cells in vitro have been impaired by the presence of nonneuronal cells, which become productively infected and destroy the cultures. We have developed an in vitro model of VZV infection in which highly pure (>95 %) terminally differentiated human neurons derived from pluripotent stem cells were infected with VZV. At 2 weeks post-infection, infected neurons appeared healthy compared to VZV-infected human fetal lung fibroblasts (HFLs), which developed a cytopathic effect (CPE) within 1 week. Tissue culture medium from VZV-infected neurons did not produce a CPE in uninfected HFLs and did not contain PCR-amplifiable VZV DNA, but cocultivation of infected neurons with uninfected HFLs did produce a CPE. The nonproductively infected neurons contained multiple regions of the VZV genome, as well as transcripts and proteins corresponding to VZV immediate-early, early, and late genes. No markers of the apoptotic caspase cascade were detected in healthy-appearing VZV-infected neurons. VZV infection of highly pure terminally differentiated human neurons provides a unique in vitro system to study the VZV-neuronal relationship and the potential to investigate mechanisms of VZV reactivation
