Claiming the moral high ground in the copyright wars

Copyright was once one of the more obscure areas of law. It applied primarily to resolve disputes between rival publishers, and there was a time, not too long ago, when ordinary people gave it no thought. Copyright disputes were like subatomic particles: everyone knew that they existed, but nobody had ever seen one. In the digital age, however, copyright has become a heated, passionate, bloody battleground. The 'copyright wars' now pitch readers against authors, pirates against publishers, and content owners against communications providers. Everyone has heard a movie producer decry the rampant infringement of streaming sites, or a music executive suggest that BitTorrent is the end of civilisation as we know it. But everyone infringes copyright on an almost constant basis - streaming amateur videos with a soundtrack that isn't quite licensed, filesharing mp3s, copying LOLcat pictures from Facebook, posting pictures on Pinterest without permission, and so on - and most know full well they're in breach of the law.

Community, Power, and Colonialism: The U.S. Army in Southern Arizona and New Mexico, 1866-1886

Empire is central to U.S. history. When we see the U.S. projecting its influence on a global scale in today s world it is important to understand that U.S. empire has a long history. This dissertation offers a case study of colonialism and U.S. empire by discussing the social worlds, labor regimes, and culture of the U.S. Army during the conquest of southern Arizona and New Mexico (1866-1886). It highlights some of the defining principles, mentalities, and characteristics of U.S. imperialism and shows how U.S. forces have in years past constructed their power and represented themselves, their missions, and the places and peoples that faced U.S. imperialism/colonialism. Using insights from postcolonial studies and whiteness studies, this work balances its attention between discursive representations (army stories) and social experience (army actions), pays attention to silences in the process of historical production, and focuses on collective group mentalities and identities. In the end the army experience reveals an empire in denial constructed on the rule of difference and marked by frustration. White officers, their wives, and the white enlisted men not only wanted the monopoly of violence for the U.S. regime but also colonial (mental/cultural) authority and power, and constructed their identity, authority, and power in discourse and in the social contexts of the everyday through difference. Engaged in warfare against the Apaches, they did not recognize their actions as harmful or acknowledge the U.S. invasion as the bloody colonial conquest it was. White army personnel painted themselves and the army as liberators, represented colonial peoples as racial inferiors, approached colonial terrain in terms of struggle, and claimed that the region was a terrible periphery with little value before the arrival of white civilization. Officers and wives also wanted to place themselves at the top of colonial hierarchies as the refined and respectable class who led the regeneration of the colony by example: they tried to turn army villages into islands of civilization and made journeys, leisure, and domestic life to showcase their class sensibilities and level of sophistication. Often, however, their efforts failed, resulting in frustration and bitterness. Many blamed the colony and its peoples for their failures. The army itself was divided by race and class. All soldiers were treated as laborers unfit for self-government. White enlisted men, frustrated by their failures in colonial warfare and by constant manual labor, constructed worlds of resistance, whereas indigenous soldiers sought to negotiate the effects of colonialism by working in the army. As colonized labor their position was defined by tension between integration and exclusion and between freedom and colonial control.

from "The Roving Party"

They walked down through a dry creek bed lined with swamp gums grown so close together they appeared as one living whole. The men passed around these trees in single file, among sun shafts which pierced the canopy but threw no light upon their faces nor warmed their bones. In the gloom the air was thick with flies and the mushrooms grew like the sightless larvae of some queer and unnamed vermin. Before long they found themselves among a stand of trees which had been stripped of their bark for windbreaks. The naked trunks were carved over with bisected circles, detailings of the moon and sun, images of snakes and roo. The Parramatta men gazed at the finely wrought icons but John Batman found more to hold his attention. Pressed onto the flesh of the tree was a bloody handprint. Batman removed his hat and crouched to examine the ground and Black Bill joined him. One injured man had passed this way...

Placental abruption : Studies on incidence, risk factors and potential predictive biomarkers

Placental abruption, one of the most significant causes of perinatal mortality and maternal morbidity, occurs in 0.5-1% of pregnancies. Its etiology is unknown, but defective trophoblastic invasion of the spiral arteries and consequent poor vascularization may play a role. The aim of this study was to define the prepregnancy risk factors of placental abruption, to define the risk factors during the index pregnancy, and to describe the clinical presentation of placental abruption. We also wanted to find a biochemical marker for predicting placental abruption early in pregnancy. Among women delivering at the University Hospital of Helsinki in 1997-2001 (n=46,742), 198 women with placental abruption and 396 control women were identified. The overall incidence of placental abruption was 0.42%. The prepregnancy risk factors were smoking (OR 1.7; 95% CI 1.1, 2.7), uterine malformation (OR 8.1; 1.7, 40), previous cesarean section (OR 1.7; 1.1, 2.8), and history of placental abruption (OR 4.5; 1.1, 18). The risk factors during the index pregnancy were maternal (adjusted OR 1.8; 95% CI 1.1, 2.9) and paternal smoking (2.2; 1.3, 3.6), use of alcohol (2.2; 1.1, 4.4), placenta previa (5.7; 1.4, 23.1), preeclampsia (2.7; 1.3, 5.6) and chorioamnionitis (3.3; 1.0, 10.0). Vaginal bleeding (70%), abdominal pain (51%), bloody amniotic fluid (50%) and fetal heart rate abnormalities (69%) were the most common clinical manifestations of placental abruption. Retroplacental blood clot was seen by ultrasound in 15% of the cases. Neither bleeding nor pain was present in 19% of the cases. Overall, 59% went into preterm labor (OR 12.9; 95% CI 8.3, 19.8), and 91% were delivered by cesarean section (34.7; 20.0, 60.1). Of the newborns, 25% were growth restricted. The perinatal mortality rate was 9.2% (OR 10.1; 95% CI 3.4, 30.1). We then tested selected biochemical markers for prediction of placental abruption. The median of the maternal serum alpha-fetoprotein (MSAFP) multiples of median (MoM) (1.21) was significantly higher in the abruption group (n=57) than in the control group (n=108) (1.07) (p=0.004) at 15-16 gestational weeks. In multivariate analysis, elevated MSAFP remained as an independent risk factor for placental abruption, adjusting for parity ≥ 3, smoking, previous placental abruption, preeclampsia, bleeding in II or III trimester, and placenta previa. MSAFP ≥ 1.5 MoM had a sensitivity of 29% and a false positive rate of 10%. The levels of the maternal serum free beta human chorionic gonadotrophin MoM did not differ between the cases and the controls. None of the angiogenic factors (soluble endoglin, soluble fms-like tyrosine kinase 1, or placental growth factor) showed any difference between the cases (n=42) and the controls (n=50) in the second trimester. The levels of C-reactive protein (CRP) showed no difference between the cases (n=181) and the controls (n=261) (median 2.35 mg/l [interquartile range {IQR} 1.09-5.93] versus 2.28 mg/l [IQR 0.92-5.01], not significant) when tested in the first trimester (mean 10.4 gestational weeks). Chlamydia pneumoniae specific immunoglobulin G (IgG) and immunoglobulin A (IgA) as well as C. trachomatis specific IgG, IgA and chlamydial heat-shock protein 60 antibody rates were similar between the groups. In conclusion, although univariate analysis identified many prepregnancy risk factors for placental abruption, only smoking, uterine malformation, previous cesarean section and history of placental abruption remained significant by multivariate analysis. During the index pregnancy maternal alcohol consumption and smoking and smoking by the partner turned out to be the major independent risk factors for placental abruption. Smoking by both partners multiplied the risk. The liberal use of ultrasound examination contributed little to the management of women with placental abruption. Although second-trimester MSAFP levels were higher in women with subsequent placental abruption, clinical usefulness of this test is limited due to low sensitivity and high false positive rate. Similarly, angiogenic factors in early second trimester, or CRP levels, or chlamydial antibodies in the first trimester failed to predict placental abruption.

Suolistopatogeenisten Escherichia coli -bakteerien esiintyvyys ripulipotilailla ja raa’oissa lihatuotteissa Burkina Fasossa sekä enterohemorraagisten E. coli -kantojen karakterisointi

Suolistopatogeeniset Escherichia coli -bakteerit eli ripulikolit aiheuttavat ihmisellä suolistoinfektioita. Kuten normaalimikrobiston E. coli -bakteerit, ne esiintyvät ihmisen lisäksi muiden nisäkkäiden, etenkin märehtijöiden, ja lintujen suolistossa. Lisäksi ne voivat esiintyä maaperässä ja vesistöissä. Ihminen voi saada tartunnan eläinperäisten elintarvikkeiden välityksellä tai juomalla eläinten tai ihmisen ulosteilla saastunutta vettä. Ripulikolit voidaan jakaa ainakin viiteen ryhmään perustuen niiden erilaisiin virulenssiominaisuuksiin: enteropatogeeninen E. coli (EPEC), enterotoksigeeninen E. coli (ETEC), enterohemorraaginen E. coli (EHEC), enteroinvasiivinen E. coli (EIEC) ja enteroaggregatiivinen E. coli (EAEC). EPEC aiheuttaa etenkin kehitysmaissa pikkulapsille ripulia. ETEC aiheuttaa turistiripulia ja vastasyntyneiden ripulia kehitysmaissa. EHEC aiheuttaa ripulia tai veriripulia, joka voi varsinkin pienillä lapsilla johtaa hemolyyttis-ureemiseen oireyhtymään (HUS) ja munuaisten vaurioitumiseen. EIEC aiheuttaa Shigellan kaltaista ripulia, joka voi olla veristä. EAEC on yhdistetty lähinnä pitkittyneisiin ripuleihin. Tutkimuksessa selvitettiin suolistopatogeenisten E. coli -bakteerien esiintyvyyttä Burkina Fasossa, josta ei ole saatavilla aikaisempaa tietoa ripulikolien esiintymisestä ihmisissä ja elintarvikkeissa. Ulostenäytteitä otettiin ripulia sairastavilta alle viisivuotiailta lapsilta maaseudulta kahdesta kylästä, Boromosta ja Gourcysta, ja maan pääkaupungista Ouagadougousta (110 näytettä). Lihanäytteitä (kanaa, nautaa, lammasta ja naudan suolta, jota käytetään ihmisravinnoksi) otettiin Ouagadougoun toreilla myytävistä kypsentämättömistä lihoista (120 näytettä). Näytteistä saadut bakteerisekaviljelmät tutkittiin monialukkeisella PCR-menetelmällä, joka tunnistaa viiden ripulikoliryhmän virulenssigeenejä. Lisäksi lihanäytteistä eristettiin 20 EHEC-kantaa shigatoksiinin stx-geenin havaitsemiseen perustuvalla pesäkehybridisaatiolla ja PCR-seulonnalla, ja karakterisoitiin mahdollisten virulenssiominaisuuksien selvittämiseksi. Tutkimus osoitti, että ripulikolien aiheuttamat suolistoinfektiot ovat yleisiä ripulia sairastavilla pikkulapsilla Burkina Fasossa. Ulostenäytteistä 59 % oli positiivisia. Useimmiten lapsilla esiintyi EAEC- (32 %) ETEC- (31 %) ja EPEC-patoryhmiä (20 %). EIEC- (2 %) ja EHEC-patoryhmiä (1 %) esiintyi vähän. Myös useamman patoryhmän sekainfektiot olivat yleisiä (24 %). Eri paikkakuntien välillä oli tilastollisesti merkitseviä eroja ripulikolien esiintymisessä. Gourcyssa ripulikoleja esiintyi useammin kuin Ouagadougoussa ja Boromossa. Tutkimuksessa kävi ilmi, että Ouagadougoun toreilla myytävissä lihoissa on paljon ripulikoleja. Lihanäytteistä 43 % oli positiivisia. Yleisimmin lihoissa esiintyi EHEC (28 %), EPEC (20 %), ETEC (8 %) ja EAEC (5 %). EIEC-ryhmää ei havaittu lihoissa. Myös useamman patoryhmän sekakontaminaatioita löytyi (17 %) lihoista. Ripulikolien esiintyvyydessä eri lihojen välillä ei ollut tilastollisesti merkitseviä eroja, kun tarkasteltiin kaikkia patoryhmiä yhdessä. Eri patoryhmien esiintyvyyttä tarkasteltaessa EHEC-patoryhmää ei esiintynyt ollenkaan kanassa ja ero oli tilastollisesti merkitsevä muihin lihoihin verrattuna. Lihoista eristetyt 20 EHEC-kantaa kuuluivat 14 eri serotyyppiin, joista osa on aikaisemmin eristetty suolistoinfektioihin ja HUSoireyhtymään sairastuneilta ihmisiltä. Kaikki kannat olivat stx1-positiivisia ja puolella oli lisäksi stx2-geeni, jota pidetään shigatoksiinin virulentimpana muotona. Kahdelta EHEC-kannalta löytyi myös ETECpatoryhmän lämpöstabiilin enterotoksiini Ia:n geeni eli kannat olivat kahden patoryhmän välimuotoa ja osoitus geenien siirtymisestä eri patoryhmien välillä. Vaikka nuorimmat näytteen antaneet lapsipotilaat tuskin söivät lihaa, sen voidaan ajatella silti olevan edustava näyte lasten elinympäristöstä, sillä lasten ruoka valmistetaan usein samoissa oloissa, joissa raakaa lihaa käsitellään. Saastunut liha voi siten olla pikkulasten ripulikoli-infektioiden aiheuttaja.

Nos fios das narradoras: tramas e urdiduras do feminino nos contos de fadas de Angela Carter e Marina Colasanti

Essa dissertação tem como objetivo a leitura comparativa dos contos de fadas da escritora inglesa Angela Carter, contidos no livro O quarto do Barba Azul, e os da ítalo-brasileira Marina Colasanti, presentes em livros como Uma ideia toda azul, Entre a rosa e a espada, Doze reis e a moça no labirinto do vento. Foram analisadas os modos pelo quais as duas autoras, através da reescrita dos contos de fadas, resistem a morte do narrador tradicional descrita por Walter Benjamin e criticam a sociedade patriarcal, revelando, naturalmente, uma postura feminista. Identificou-se, ainda, como estratégias poéticas comuns à escrita de ambas as autoras, aspectos intertextuais como a paródia, o palimpsesto e o pastiche

The Great Albatross Philippine Expedition and Its Fishes

The Philippine Expedition of 1907-10 was the longest and most extensive assignment of the Albatross's 39-year career. It came about because the United States had acquired the Philippines following the Spanish-American War of 1898 and the bloody Philippine Insurection of 1899-1902. The purpose of the expedition was to surbey and assess the aquatic resources of the Philippine Islands. Dr. Hugh M. Smith, the Deputy Commissioner of the U.S. Bureau of Fisheries, was the Director of the Expedition. Other scientific participants were Frederick M. Chamberlain, Lewis Radcliffe, Paul Bartsch, Harry C. Fasset, Clarence Wells, Albert Burrows, Alvin Seale, and Roy Chapman Andrews. The expedition consisted of a series of cruises, each beginning and ending in Manila and exploring a different part of the island group. In addition to the Philippines proper, the ship also explored parts of the Dutch East Indies and areas around Hong Kong and Taiwan. The expedition returned great quantities of fish and invertebrate speciments as well as hydrographic and fisheries data; most of the material was eventually deposited in the Smithsonian Institution's National Museum of Natural History. The fisehs were formally accessioned into the museum in 1922 and fell under the car of Barton A. Bean, Assistant Curator of Fishes, who then recruited Henry W. Fowler to work up the material. Fowler completed his studies of the entire collection, but only part of it was ever published, due in part to the economic constraints caused by the Depression. The material from the Philippine Expedition constituted the largest single accession of fishes ever received by the museum. These speciments are in good condition today and are still being used in scientific research.

Avaliação da interação de Escherichia coli enterohemorrágica (EHEC) pertencente ao sorotipo O157: H7 isoladas de bovinos assintomáticos e de doença humana com células enterocíticas humanas (linhagem Caco-2)

Reconhecida como agente de doença humana em 1982, E.coli enterohemorrágica (EHEC) pode causar diarréia sanguinolenta, colite hemorrágica e síndrome hemolítica urêmica (SHU). EHEC constitui um subgrupo especialmente virulento das E.coli produtoras de toxina de Shiga (Stx). O fator crítico da sua virulência é a toxina Shiga, capaz de interromper a síntese proteica da célula eucariótica. São conhecidos dois subgrupos de Stx, Stx1 e Stx2. Stx1 possui duas variantes Stx1c e Stx1d. Stx2 possui muitas variantes. Estudos epidemiológicos sugerem que cepas com os perfis toxigênicos Stx2 ou Stx2/Stx2c seriam mais frequentemente associadas a pacientes com SHU. Além da expressão de Stx, EHEC do sorotipo O157:H7 colonizam a mucosa intestinal induzindo a formação de lesões denominadas attaching/effacing (A/E). Para a produção da lesão A/E, é necessária a presença de uma ilha de patogenicidade cromossômica denominada LEE, composta por cinco operons, LEE 1 a LEE5. Em LEE 5 são codificadas a adesina intimina e o seu receptor Tir, o qual é translocado por um sistema de secreção tipo III (SSTT) e em LEE 4 são codificadas as proteínas secretadas EspA,B e D. Em EHEC O157:H7 são descritos muitos fatores de virulência, codificados em ilhas de patogenicidade, no cromossomo e no megaplasmídio pO157. Bovinos são o principal reservatório deste patógeno e alimentos de origem bovina e produtos contaminados com fezes de bovinos são causadores de surtos epidêmicos. Em nosso país EHEC O157:H7 é isolada do reservatório animal mas é muito rara a sua ocorrência em doença humana. Notamos que nas cepas bovinas predomina Stx2c, enquanto nas cepas humanas predomina o perfil toxigenico Stx2/Stx2c. Quanto a interação com enterocitos humanos cultivados in vitro (linhagem Caco-2), verificamos que tanto cepas bovinas quanto humanas mostram idêntica capacidade de invadir e persistir no compartimento intracelular das células Caco-2. No entanto, em comparação com as cepas humanas, as cepas bovinas mostram uma reduzida capacidade de produzir lesões A/E. Empregamos qPCR para aferir a transcrição de três diferentes locus (eae, espA e tir) situados nos operons LEE4 e LEE5 de cepas bovinas e humanas, durante a infecção de células Caco-2. Verificamos diferenças na expressão dos genes, especialmente espA, entre cepas bovinas e humanas com maior expressão para estas ultimas, em linha com os achados dos testes FAS. Através de clonagem e expressão de proteínas recombinantes, purificamos as proteínas Eae, EspA e Tir e obtivemos anticorpos específicos, empregados para acompanhar a sua expressão ao longo da infecção de células Caco-2, por imunofluorescencia. Verificamos que as três proteínas são detectadas tanto em cepas bovinas quanto humanas, mas nestas ultimas, a marcação é precoce e torna-se mais intensa com o avanço da infecção. Nossos resultados indicam que cepas EHEC O157:H7 isoladas do reservatório bovino em nosso país apresentam diferenças importantes em relação ao perfil toxigenico e a capacidade de indução de lesões A/E, características apontadas na literatura como relevantes para a virulência do micro-organismo. Por outro lado, nossos achados quanto a capacidade de invadir e multiplicar-se no interior de enterócitos pode explicar a persistência do patógeno no reservatório animal e a sua capacidade de transmissão horizontal.

La reproducción de la merluza en el Mar Argentino (Merlucciidae, Meluccius merluccius hubbsi) : 1. Descripción histológica del ciclo del ovario de merluza

The present paper deals on the histological description of the hake ovary made on the basis of gonad observations of 394 females during the period April 1966 March 1967. The material was obtained from weekly sampling of commercial catches carried out at the Institute of Marine Biology (Prov. Buenos Aires, Argentina). The anatomical and histological description of the standard ovary and the adopted terminology are given. The maturation process is divided into five periods, from ovocyte formation to yolked ovocyte formation, with its histological description. Ovary changes are analyzed on detail. The following conclusions were outlined: 1. Analysis demonstrated that although some specimens were totally spawned others, at the end of the spawning period, retaining a great number of ovocytes in different maturity stages. Therefore, postspawners have been classified as follows: Postspawned II : This stages is characterized by the empty ovarian structure, with ovocytes in stage II, which will remain in the resting phase untill next spawning season. Postspawned III and IV: Their main characteristics are: tissue destruction, bloody residuals and remaining ovocytes in stage III and IV, respectively. 2. Some transformations were found in ovaries of postspawned III and IV. They are classified as follows, according to its origin and structure: Developed from follicular cell membrane – a) Glandular formations, b) Epiteloid formations - Originated from remaining ovocytes, c) Ovocyte disintegration, d) Ovocyte with follicular cell infiltration. 3. All those structures derived from postpawners III and IV have a temporary character and will be reabsorbed. Their presence delay the recuperation of the organ and its reproductive functions. Consequently, the possibility of those structures acting as control mechanisms is suggested. 4. Transformations pointed out in paragraph Nº 2 prevent the possibility of consecutive spawning originated from the remaining ovocytes (II and IV). 5. No structures originated from postspawners III and IV were found during summer season. 6. Reproductive cycle of hake has been described monthly. It was observed that maturing ovaries predominate in summer (November-December).

Composition portfolio and commentaries

In an attempt to provide an analytical entry point into my compositional practice, I have identified eight themes which are significantly recurrent: reduction – the selection of a small number of elements; imperfection – a damaged or warped characteristic of sound; hierarchy – a concern with the roles of instruments with regard to their relative prominence; motion – apparently static sound masses consist of fine internal movement; listener perception – expectations for change influence the experience of affect; translation – the transitioning of electronic sounds to the acoustic realm, and vice versa; immersion – the creation of an accommodating soundscape; blurring – smearing and overlapping sounds or genres. Each of these eight factors is associated with relevant precedents in the history and theory of music that have been influential on my work. These include the minimalist compositions of Steve Reich and Arvo Pärt; the lo-fi aesthetic of Boards of Canada and My Bloody Valentine; concerns with political hierarchy in the work of Louis Andriessen; the variations of dynamics and microtonal shifts of Giacinto Scelsi; Leonard B. Meyer's account of expectation in music; cross-fertilisation of the acoustic and electronic in pieces by Gérard Grisey and Gyorgy Ligeti; the immersive technique of Brian Eno's ambient music; and the overlapping sounds of Aphex Twin. These eight factors are variously applicable to the eleven submitted pieces, which are individually analysed with reference to the most significant of the categories. Together they form a musical language that sustains the interaction of a variety of techniques, concepts and genres.

Ecological impacts of an invasive predator explained and predicted by comparative functional responses

Forecasting the ecological impacts of invasive species is a major challenge that has seen little progress, yet the development of robust predictive approaches is essential as new invasion threats continue to emerge. A common feature of ecologically damaging invaders is their ability to rapidly exploit and deplete resources. We thus hypothesized that the 'functional response' (the relationship between resource density and consumption rate) of such invasive species might be of consistently greater magnitude than those of taxonomically and/or trophically similar native species. Here, we derived functional responses of the predatory Ponto-Caspian freshwater 'bloody red' shrimp, Hemimysis anomala, a recent and ecologically damaging invader in Europe and N. America, in comparison to the local native analogues Mysis salemaai and Mysis diluviana in Ireland and Canada, respectively. This was conducted in a novel set of experiments involving multiple prey species in each geographic location and a prey species that occurs in both regions. The predatory functional responses of the invader were generally higher than those of the comparator native species and this difference was consistent across invaded regions. Moreover, those prey species characterized by the strongest and potentially de-stabilizing Type II functional responses in our laboratory experiments were the same prey species found to be most impacted by H. anomala in the field. The impact potential of H. anomala was further indicated when it exhibited similar or higher attack rates, consistently lower prey handling times and higher maximum feeding rates compared to those of the two Mysis species, formerly known as 'Mysis relicta', which itself has an extensive history of foodweb disruption in lakes to which it has been introduced. Comparative functional responses thus merit further exploration as a methodology for predicting severe community-level impacts of current and future invasive species and could be entered into risk assessment protocols.

Treatment of intestinal Behçet's syndrome with chimeric tumour necrosis factor alpha antibody

Few patients with Behçet's syndrome have gastrointestinal ulceration. Such patients are difficult to treat and have a higher mortality. Faced with refractory symptoms in two patients with intestinal Behçet's, we used the tumour necrosis factor alpha (TNF-alpha) monoclonal antibody infliximab to induce remission. Both women (one aged 27 years, the other 30 years) presented with orogenital ulceration, pustular rash, abdominal pain, bloody diarrhoea due to colonic ulceration, weight loss, and synovitis. One had thrombophlebitis, digital vasculitis, perianal fistula, and paracolic abscess; the other had conjunctivitis and an ulcer in the natal cleft. Treatment with prednisolone, methyl prednisolone, and thalidomide in one and prednisolone, colchicine, and cyclosporin in the other was ineffective. After full discussion, infliximab (3 mg/kg, dose reduced because of recent sepsis in one, and 5 mg/kg in the other) was administered. Within 10 days the ulcers healed, with resolution of bloody diarrhoea and all extraintestinal manifestations. A second infusion of infliximab was necessary eight weeks later in one case, followed by sustained (>15 months) remission on low dose thalidomide. Remission was initially sustained for 12 months in the other but thalidomide had to be stopped due to intolerance, and a good response to retreatment lasted only 12 weeks without immunosuppression, before a third infusion. The cause of Behçet's syndrome is unknown but peripheral blood CD45 gammadelta T cells in Behçet's produce >50-fold more TNF-alpha than controls when stimulated with phorbol myristate acetate and anti-CD3. Infliximab could have a role for inducing remission in Behçet's syndrome.
