Intestinal helminths of capybaras, Hydrochoerus hydrochaeris, from Venezuela

Quantitative parameters of intestinal helminth species and their potential relations to host characteristics in a population of capybaras (Hydrochoerus hydrochaeris) from Venezuela are reported for the first time. The intestines of 40 capybaras were collected during the 1992-annual harvest at Hato El Cedral. Six helminth species were found: 2 cestodes (Monoecocestus macrobursatum, M. hagmanni), 2 nematodes (Viannella hydrochoeri, Protozoophaga obesa), and 2 trematodes (Hippocrepis hippocrepis, Taxorchis schistocotyle). This is the first report for M. macrobursatum in Venezuela. Helminth abundance did not differ between sexes or age classes. Although patterns of distribution for all helminth species were overdispersed, the high prevalence found for all species (over 70%) and the high abundance observed for nematodes made it difficult to assess the effect that these helminths may produce on capybaras. Nevertheless, the negative associations found between the body condition of capybaras and helminth intensity for M. macrobursatum and V. hydrochoeri, might be pointing out potential host population regulatory role for these parasites which require further research.

Amphetamines for Attention Deficit Hyperactivity Disorder (ADHD) in adults.

Attention Deficit Hyperactivity Disorder (ADHD) is a childhood onset psychiatric disorder that can persist into adulthood in up to 50% of patients. From a clinical point of view, ADHD is characterized by hyperactivity, mood instability, irritability, difficulties in maintaining attention, lack of organization and impulsive behaviours. The presence of other disorders occurring at the the same time is also common, especially mood disorders and substance abuse. It seems that amphetamines could reverse the underlying neurological problems that feature in ADHD, and so improve ADHD symptoms. We found seven studies, which enrolled 1091 patients. These studies compared amphetamines to placebo and three of them also compared amphetamines with other drugs: guanfacine, modafinil and paroxetine. Three amphetamine derivatives were investigated: dexamphetamine, lisdexamphetamine and mixed amphetamine salts (MAS). Treatment length ranged from two to 20 weeks. All amphetamines improved ADHD symptoms but overall they did not make people more likely to stay in treatment and were associated with a higher risk of treatment ending early due to adverse events. One type of amphetamine, mixed amphetamine salts, did, however, increase retention in treatment. We found no evidence that higher doses worked better than lower ones. We did not find any difference in effectiveness between immediate-release and sustained-release formulations. Therefore, it appears that short-term treatment with amphetamines reduces ADHD symptoms, but studies assessing the effects of amphetamines for longer periods of time are needed.This resource was contributed by The National Documentation Centre on Drug Use.

Fraser syndrome: epidemiological study in a European population.

Fraser syndrome is a rare autosomal recessive disorder characterized by cryptophthalmos, cutaneous syndactyly, laryngeal, and urogenital malformations. We present a population-based epidemiological study using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network of birth defect registries. Between January 1990 and December 2008, we identified 26 cases of Fraser syndrome in the monitored population of 12,886,464 births (minimal estimated prevalence of 0.20 per 100,000 or 1:495,633 births). Most cases (18/26; 69%) were registered in the western part of Europe, where the mean prevalence is 1 in 230,695 births, compared to the prevalence 1 in 1,091,175 for the rest of Europe (P = 0.0003). Consanguinity was present in 7/26 (27%) families. Ten (38%) cases were liveborn, 14 (54%) pregnancies were terminated following prenatal detection of a serious anomaly, and 2 (8%) were stillborn. Eye anomalies were found in 20/24 (83%), syndactyly in 14/24 (58%), and laryngeal anomalies in 5/24 (21%) patients. Ambiguous genitalia were observed in 3/24 (13%) cases. Bilateral renal agenesis was present in 12/24 (50%) and unilateral in 4/24 (17%) cases. The frequency of anorectal anomalies was particularly high (42%). Most cases of Fraser syndrome (85%) are suspected prenatally, often due to the presence of the association of renal agenesis and cryptophthalmos. In the European population, a high proportion (82%) of pregnancies is terminated, thus reducing the live birth prevalence to a third of the total prevalence rate.

Construcció d'un SIG municipal Aplicat a les necessitats bàsiques d'una població qualsevol

Els Sistemes d'Informació Geogràfics (SIG), han estat fins ara una eina molt potent a l'hora de gestionar molts aspectes relacionat amb el terreny. En aquest document, s'intenta posar de manifest aquest fet, i per portar a terme aquest objectiu, s'ha estructurat en dos grans blocs, un teòric, i un altre pràctic, que es complementen amb un tercer, més específic, que amplia, amb aspectes teòrics, la part pràctica del TFC, que tracta sobre temes cadastrals.

Antibodies to Rickettsia rickettsii, Rickettsia typhi, Coxiella burnetii, Bartonella henselae, Bartonella quintana, and Ehrlichia chaffeensis among healthy population in Minas Gerais, Brazil

Rickettsial diseases except those belonging to spotted fever group rickettsioses are poorly studied in South America particularly in Brazil where few epidemiological reports have been published. We describe a serosurvey for Rickettsia rickettsii, R. typhi, Coxiella burnetii, Bartonella henselae, B. quintana, and Ehrlichia chaffeensis in 437 healthy people from a Brazilian rural community. The serum samples were tested by indirected micro-immunoflourescence technique and a cutoff titer of 1:64 was used. The seroprevalence rates for R. rickettsii, R. typhi, C. burnetii, B. henselae, B. quintana, and E. chaffeensis were respectively 1.6% (7 samples); 1.1% (5 samples); 3.9% (17 samples); 13.7% (60 samples); 12.8% (56 samples), and 10.5% (46 samples). Frequent multiple/cross-reactivity was observed in this study. Age over 40 years old, urban profession, and rural residence were significantly associated with some but not all infections rate. Low seropositivity rates for R. rickettsii, R. typhi, and C. burnetii contrasted with higher rates of seropositivity for B. quintana, B. henselae, and E. chaffeensis. These results show that all tested rickettsial species or antigenically closely related possible exist in this particular region.

Effect of fosmidomycin on metabolic and transcript profiles of the methylerythritol phosphate pathway in Plasmodium falciparum

In Plasmodium falciparum, the formation of isopentenyl diphosphate and dimethylallyl diphosphate, central intermediates in the biosynthesis of isoprenoids, occurs via the methylerythritol phosphate (MEP) pathway. Fosmidomycin is a specific inhibitor of the second enzyme of the MEP pathway, 1-deoxy-D-xylulose-5-phosphate reductoisomerase. We analyzed the effect of fosmidomycin on the levels of each intermediate and its metabolic requirement for the isoprenoid biosynthesis, such as dolichols and ubiquinones, throughout the intraerythrocytic cycle of P. falciparum. The steady-state RNA levels of the MEP pathway-associated genes were quantified by real-time polymerase chain reaction and correlated with the related metabolite levels. Our results indicate that MEP pathway metabolite peak precede maximum transcript abundance during the intraerythrocytic cycle. Fosmidomycin-treatment resulted in a decrease of the intermediate levels in the MEP pathway as well as in ubiquinone and dolichol biosynthesis. The MEP pathway associated transcripts were modestly altered by the drug, indicating that the parasite is not strongly responsive at the transcriptional level. This is the first study that compares the effect of fosmidomycin on the metabolic and transcript profiles in P. falciparum, which has only the MEP pathway for isoprenoid biosynthesis.

Art contemporani xinès en el segle XXI : introducció a la pugna entre la creació i el mercat a través de cinc artistes destacats i les seves cotitzacions en les subhastes

En el relativament breu lapse de temps que suposen les tres darreres dècades, l'art contemporani xinès ha passat de ser pràcticament invisible i desconegut per al públic general, a ser present en un gran nombre d'escenaris a nivell internacional relacionats amb el món de l'art, sobre tot des de finals de la dècada dels noranta. El present TdR ha intentat apropar-se a qüestions com la imatge i les idees que sobre la RP Xina s'han transmès en l'última dècada a través de les obres o de les accions dels artistes xinesos contemporanis més exposats o cotitzats internacionalment i que viuen a la Xina, i a com s'ha arribat a inserir la producció artística d'aquests autors en el procés de globalització i hibridació de la cultura que estem vivint. Hem delimitat el camp de recerca, bàsicament a l'estudi de l'obra de cinc autors (Song Dong, Ai Weiwei, Zeng Fanzhi, Yue Minjun i Wang Qingsong) i a la seva presència en l'escena internacional de l'art contemporani a través de les subhastes de les dues cases més importants del món, Christie's i Sotheby's.
