HGNC: The Why and How of Standardised Gene Nomenclature

The HUGO Gene Nomenclature Committee (HGNC) aims to approve a unique gene symbol and gene name for every human gene. Standardisation of gene symbols is necessary to allow researchers and curators to refer to the same gene without ambiguity. Consistent use of gene symbols in publications and across different websites makes it easy for researchers to find all relevant information for a particular gene and facilitates data mining and retrieval. For each gene that we name we curate relevant information including symbol aliases, chromosomal location, locus type, sequence accessions and links to relevant databases. Therefore, our website is a central resource for human genetics. 
 
We endeavour to approve gene symbols that are acceptable to researchers to encourage widespread use of our symbols. In order to achieve this, we contact researchers that work on particular genes for advice before approving symbols and allow researchers to submit gene symbols to us directly for our consideration. We attend conferences to discuss difficult nomenclature matters and to gain community agreement. We interact with annotators of genes and proteins to provide symbols and names that accurately reflect the nature of each gene and its products. We also work with the gene nomenclature committees for other organisms, and aim to approve equivalent gene symbols for orthologous genes in human and other vertebrate species, especially mouse and rat. 
 
We will demonstrate the steps that are required to name a gene, and will show how and where the nomenclature of a particular gene is used. We will also explain the nature of our collaborations with particular journals and other databases in striving to achieve the use of a common gene nomenclature by all

Filtration of Carbon Particulate Emissions from a Plasma Pyrolysis Assembly

NASA is investigating plasma pyrolysis as a candidate technology that will enable the recovery of hydrogen from the methane produced by the ISS Sabatier Reactor. The Plasma Pyrolysis Assembly (PPA) is the current prototype of this technology which converts the methane product from the Carbon Dioxide Reduction Assembly (CRA) to acetylene and hydrogen with 90% or greater conversion efficiency. A small amount of solid carbon particulates are generated as a side product and must be filtered before the acetylene is removed and the hydrogen-rich gas stream is recycled back to the CRA. We discuss developmental work on several options for filtering out the carbon particulate emissions from the PPA exit gas stream. The filtration technologies and concepts investigated range from fibrous media to monolithic ceramic and sintered metal media. This paper describes the different developed filter prototypes and characterizes their performance from integrated testing at the Environmental Chamber (E-Chamber) at MSFC. In addition, characterization data on the generated carbon particulates, that help to define filter requirements, are also presented

Development of a histopathology scoring system for the pulmonary complications of organophosphorus insecticide poisoning in a pig model

Organophosphorus (OP) insecticide self-poisoning causes over 100,000 global deaths annually. Around a third of patients are intubated and up to half of these can die. Post-mortem analysis of OP poisoned patients' lungs reveals consolidation, edema and hemorrhage, suggesting that direct or indirect lung damage may contribute to mortality. The lung injury caused by these formulated agricultural preparations is poorly characterised in humans, and a valid histopathology scoring system is needed in a relevant animal model to further investigate the disease and potential treatments. We conducted two pilot studies in anesthetized minipigs, which are commonly used for toxicological studies. In the first, pigs were given 2.5 mL/kg of either OP (n = 4) or saline (n = 2) by gavage and compared with positive controls (iv oleic acid n = 2). The second study simulated ingestion followed by gastric content aspiration: mixtures of OP (n = 3) or saline (n = 2) (0.63-0.71mL/kg) were placed in the stomach, and then small volumes of the gastric content were placed in the lung. At post-mortem examination, lungs were removed and inflation-fixed with 10% neutral buffered formalin. Samples (n = 62) were taken from cranial and caudal regions of both lungs. Two experienced lung histopathologists separately scored these samples using 8 proposed features of damage and their scores related (Kendall rank order). Two elements had small and inconsistent scores. When these were removed, the correlation increased from 0.74 to 0.78. Eight months later, a subset of samples (n = 35) was re-scored using the modified system by one of the previous histopathologists, with a correlation of 0.88. We have developed a reproducible pulmonary histopathology scoring system for OP poisoning in pigs which will assist future toxicological research and improve understanding and treatment of human OP poisoning

Lung injury caused by aspiration of organophosphorus insecticide and gastric contents in pigs

INTRODUCTION: Patients who require mechanical ventilation after self-poisoning with ingested organophosphorus (OP) insecticides often die. Aspiration of stomach contents may contribute to lung injury and lethality. This study was designed to assess the severity of direct and indirect pulmonary injury created by pulmonary instillation of mixtures of OP insecticide, solvent (Solv) and porcine gastric juice (GJ) compared to controls. METHODS: Terminally anaesthetised minipigs (groups n = 5) were exposed to sham bronchoscopy or given mixtures (0.5 mL/kg) of: saline, GJ, OP insecticide and GJ (OP + GJ), or Solv and GJ (Solv + GJ), placed into the right lung, and monitored for 48 h. Lung injury was assessed through analysis of bronchoalveolar lavage fluid (BALF), computed tomography and histopathology. RESULTS: OP + GJ created a direct lung injury consisting of neutrophil infiltration, oedema and haemorrhage, as well as indirect injury to the other lung. OP + GJ directly-injured lung parenchyma had increased concentrations of BALF protein, albumin, IL-6, IL-8 and C-reactive protein (CRP) at 24 h (p < 0.05), and BALF protein, albumin and CRP at 48 h (p < 0.05), when compared with controls. Aspiration of GJ produced similar direct effects to OP + GJ but less indirect lung injury. Lung injury was less severe after Solv + GJ, for combined lung histopathology scores (vs. OP + GJ, p < 0.05) and for the proportion of directly-injured lung that was poorly/non-aerated at 48 h. CONCLUSION: Pulmonary instillation of OP + GJ created more lung damage than controls or Solv + GJ. In patients with severe OP insecticide poisoning and reduced consciousness, early airway protection is likely to reduce pulmonary damage

Captured by the camera's eye: Guantanamo and the shifting frame of the Global War on Terror

In January 2002, images of the detention of prisoners held at US Naval Station Guantanamo Bay as part of the Global War on Terrorism were released by the US Department of Defense, a public relations move that Secretary of Defense Donald Rumsfeld later referred to as ‘probably unfortunate’. These images, widely reproduced in the media, quickly came to symbolise the facility and the practices at work there. Nine years on, the images of orange-clad ‘detainees’ – the ‘orange series’ – remain a powerful symbol of US military practices and play a significant role in the resistance to the site. However, as the site has evolved, so too has its visual representation. Official images of these new facilities not only document this evolution but work to constitute, through a careful (re)framing (literal and figurative), a new (re)presentation of the site, and therefore the identities of those involved. The new series of images not only (re)inscribes the identities of detainees as dangerous but, more importantly, work to constitute the US State as humane and modern. These images are part of a broader effort by the US administration to resituate its image, and remind us, as IR scholars, to look at the diverse set of practices (beyond simply spoken language) to understand the complexity of international politic

All used mixed method designs and two had an intervention designed to improve how care home staff provided end of life care. The EVIDEM EoL and EPOCH studies tracked the care of older people in care homes over a period of 12 months. The TTT study collected resource use data of care home residents for three months, and surveyed decedents' notes for ten months, Results: Across the three studies, 29 care homes, 528 residents, 205 care home staff, and 44 visiting health care professionals participated. Analysis of showed that end of life interventions for people with dementia were characterised by uncertainty in three key areas; what treatment is the 'right' treatment, who should do what and when, and in which setting EoL care should be delivered and by whom? These uncertainties are conceptualised as Treatment uncertainty, Relational uncertainty and Service uncertainty. This paper proposes an emergent framework to inform the development and evaluation of EoL care interventions in care homes. Conclusion: For people with dementia living and dying in care homes, EoL interventions need to provide strategies that can accommodate or "hold" the inevitable and often unresolvable uncertainties of providing and receiving care in these settingsPeer reviewe
