Green Criminology Before ‘Green Criminology’: Amnesia and Absences
Although the first published use of the term ‘green criminology’ seems to have been made by Lynch (Green criminology. Aldershot, Hampshire, 1990/2006), elements of the analysis and critique represented by the term were established well before this date. There is much criminological engagement with, and analysis of, environmental crime and harm that occurred prior to 1990 that deserves acknowledgement. In this article, we try to illuminate some of the antecedents of green criminology. Proceeding in this way allows us to learn from ‘absences’, i.e. knowledge that existed but has been forgotten. We conclude by referring to green criminology not as an exclusionary label or barrier but as a symbol that guides and inspires the direction of research
Transcription analysis on response of swine lung to H1N1 swine influenza virus
<p>Abstract</p> <p>Background</p> <p>As a mild, highly contagious, respiratory disease, swine influenza always damages the innate immune systems, and increases susceptibility to secondary infections which results in considerable morbidity and mortality in pigs. Nevertheless, the systematical host response of pigs to swine influenza virus infection remains largely unknown. To explore it, a time-course gene expression profiling was performed for comprehensive analysis of the global host response induced by H1N1 swine influenza virus in pigs.</p> <p>Results</p> <p>At the early stage of H1N1 swine virus infection, pigs were suffering mild respiratory symptoms and pathological changes. A total of 268 porcine genes showing differential expression (DE) after inoculation were identified to compare with the controls on day 3 post infection (PID) (Fold change ≥ 2, p < 0.05). The DE genes were involved in many vital functional classes, mainly including signal transduction, immune response, inflammatory response, cell adhesion and cell-cell signalling. Noticeably, the genes associated with immune and inflammatory response showed highly overexpressed. Through the pathway analysis, the significant pathways mainly concerned with Cell adhesion molecules, Cytokine-cytokine receptor interaction, Toll-like receptor signaling pathway and MAPK signaling pathway, suggesting that the host took different strategies to activate these pathways so as to prevent virus infections at the early stage. However, on PID 7, the predominant function classes of DE genes included signal transduction, metabolism, transcription, development and transport. Furthermore, the most significant pathways switched to PPAR signaling pathway and complement and coagulation cascades, showing that the host might start to repair excessive tissue damage by anti-inflammatory functions. These results on PID 7 demonstrated beneficial turnover for host to prevent excessive inflammatory damage and recover the normal state by activating these clusters of genes.</p> <p>Conclusions</p> <p>This study shows how the target organ responds to H1N1 swine influenza virus infection in pigs. The observed gene expression profile could help to screen the potential host agents for reducing the prevalence of swine influenza virus and further understand the molecular pathogenesis associated with H1N1 infection in pigs.</p
Allergotoxicology: Research of Pollutant Influence on the Development of Allergic Reactions
Alergotoksikologija je znanstvenoistraživačko područje koje se bavi ispitivanjem utjecaja polutanata (onečišćivača zraka) na nastanak alergijskih reakcija i bolesti. Ispitivanja su prvobitno bila usmjerena na polutante vanjskih prostora, a u novije vrijeme sve više na polutante unutarnjih prostora u kojima ljudi provode većinu vremena. Polutanti po svojoj prirodi mogu biti krute, tekuće ili plinovite čestice, koje se razlikuju s obzirom na veličinu, sastav i izvor iz kojeg nastaju. S obzirom na izvor mogu biti biološkog i
nebiološkog podrijetla. Polutanti koji su predmet suvremenih istraživanja s gledišta nastanka alergijskih bolesti su respirabilne krute čestice, ozon, dušični oksidi i bioaerosoli. Mehanizam djelovanja polutanata ovisi o veličini čestica, njihovoj topljivosti i mjestu ulaska u organizam. Dosadašnja ispitivanja su pokazala
da različite čestice uvjetuju različite imunosne i neimunosne odgovore u organizmu. Interakcija polutanata i alergena može se zbivati izvan eksponirane osobe, tj. sa samim alergenom ili u eksponiranoj osobi na sluznicama i koži. Polutanti mogu biti nosioci alergena i mogu interferirati na različitim nivoima u nastanku alergijske reakcije. U ovom prikazu razma raju se dosadašnja saznanja o mehanizmima djelovanja polutanata na alergene, na imunosni sustav izloženih osoba na osnovi epidemioloških populacijskih istraživanja, kliničkih studija ekspozcije u kontroliranim uvjetima i eksperimentalnih testnih sistema in vivo i in vitro.Allergotoxicology studies the infl uence of pollutants on the development of allergic reactions and diseases. At the beginning, the research was focused on outdoor air pollutants, while recently it turns to the indoor environment, mainly because people this is where people spend most of their time. Air pollutants may be solid, soluble, or gaseous particles in nature, and they can differ in size, structure, and sources. Pollutants can be of biological or nonbiological origin. Currently interesting air pollutants include particulate matter, ozone, nitrogen oxides, and bioaerosols. The mechanisms of pollutant activity depend on the particle size, solubility, site of deposition, and specifi c chemical properties. Recent studies have shown that different pollutants provoke different immunological and nonimmunological responses in exposed persons. Interaction between air pollutants and allergens can take place outside the exposed person i.e. with allergen itself, or inside the organism on mucous membranes and skin. Pollutants may be the carriers of allergens and may exacerbate allergic reactions and diseases. This review presents recent views about the mechanisms of pollutant activity on allergens and immune system response in exposed persons, based on epidemiological population studies, clinical studies of exposure under controlled conditions, and experimental tests in vitro and in vivo
