Interrelationships of the Haploporinae (Digenea: Haploporidae): A molecular test of the taxonomic framework based on morphology
2009
The taxonomic framework of the Haploporidae is evaluated and the relationships within the Haploporinae are assessed for the first time at the generic level using molecular data. Partial 28S and complete ITS2 rDNA sequences from representatives of six of the nine recognised genera within the Haploporinae were analysed together with published sequences representing members of two haploporid subfamilies and of the closely related family Atractotrematidae. Molecular analyses revealed: (i) a close relationship between the Atractotrematidae and the Haploporidae; (ii) strong support for the monophyly of the Haploporinae, Dicrogaster and Saccocoelium, and the position of Ragaia within the Haplopori…
Influencia de factores intrínsecos y extrínsecos sobre la evolución postincendio de la comunidad helmintiana del ratón de campo, Apodemus sylvaticus,…
2015
A lo largo de casi dos décadas se ha estado analizando el papel de los helmintos del ratón de campo, Apodemus sylvaticus, como bioindicadores del proceso de regeneración postincendio en el ecosistema de bosque mediterráneo del Parc Natural de la Serra Calderona, entre las provincias de Castelló y València. Formando parte de este proyecto multidisciplinar, se analiza la influencia de factores intrínsecos y extrínsecos sobre la evolución postincendio de las 10 especies componentes de la comunidad helmintiana del ratón de campo, 18 años después del incendio forestal. El análisis se ha llevado a cabo sobre 917 A. sylvaticus, 675 procedentes de las zonas quemadas y 242 de las zonas control. Las …
Anaphylaxis caused by helminths: review of the literature.
2012
BACKGROUND: Anaphylaxis is a severe, life-threatening, generalized or systemic hypersensitivity reaction. In many individuals with anaphylaxis a pivotal role is played by IgE and the high-affinity IgE receptor on mast cells or basophils. Less commonly, it is triggered through other immunologic mechanisms, or through nonimmunologic mechanisms. The human immune response to helminth infections is associated with elevated levels of IgE, tissue eosinophilia and mastocytosis, and the presence of CD4+ T cells that preferentially produce IL-4, IL-5, and IL-13. Individuals exposed to helminth infections may have allergic inflammatory responses to parasites and parasite antigens. AIM: To summarize th…
Vertauskuvat osana maanalaisia poliittisia lentolehtiä sortovuosina 1899-1903
2012
Tutkimuksessa analysoidaan Suomessa ensimmäisellä sortokaudella ilmestyneiden maanalaisten lentolehtien sisältämää vertauskuvallisuutta. Työn alkuperäislähteinä on käytetty poliittisen funktion omaavia lentolehtiä, pienpainatteita. Lentolehdet olivat luonteeltaan venäläisvastaisia ja niissä sortokauden oikeustaistelua edustaneet rintamat kävivät kiivasta kamppailua keskenään siitä, miten helmikuun manifestin mukanaan tuomiin venäläisiin asetuksiin oli suhtauduttava. Viholliskuvaus ja isänmaallinen paatos kulkevat työssäni rinta rinnan punaisena lankana, limittäisinä diskursseina. Tutkimusote on laadullinen ja siinä määrin aatehistoriallinen, että tavoitteena on etsiä vertauskuvien takaa Suo…
Toxocara canis infection induces antigen-specific IL-10 and IFNγ production in pregnant dogs and their puppies
2005
Toxocara canis (T. canis) is originally a parasite of canine bitches and their pups. The pathogenicity of T. canis infection is enhanced during pregnancy and puppyhood. The aim of this study was to investigate if modification of IFNgamma and IL-10 secretion occurs during infection in pregnant dogs and puppies. Analysis of cytokines secreted could let us hypothesize a role for IL-10 and/or IFNgamma in T. canis infection. We tested T. canis-specific production of IFNgamma and IL-10 by lymphocytes of pregnant dogs and their puppies after in vitro re-exposure to purified excretory/secretory antigen (ESAg) from T. canis. Blood mononuclear cells (BMC) isolated from pregnant dogs and their puppies…
