Trypanosoma cruzi trypomastigotes are able to resist lysis via the complement system, which involves many surface proteins including the complement regulatory protein (CRP). To examine the diversity in CRP recognition among strains of T. cruzi, the expression levels of the translated protein on trypomastigote surfaces were analyzed by flow cytometry, and associations between protein expression and the biological behavior of these strains, especially the ability to induce lytic antibodies in animal models, were assessed...

Vetiver (Chrysopogon zizanioides) is a fast-growing, high biomass producing plant employed for environmental rehabilitation. The study evaluated the effects of arbuscular mycorrhizal fungi (AMF) in the growth and trace element phytoextracting capabilities of vetiver in a substrate containing coalmine wastes in Southern Brazil. AMF included Acaulospora colombiana, A. morrowiae, A. scrobiculata, Dentiscutata heterogama, Gigaspora margarita and Rhizophagus clarus. From those, A. colombiana, G. margarita and R...

Trypanosoma cruzi species is categorized into six discrete typing units (TcI to TcVI) of which TcI is most abundantly noted in the sylvatic transmission cycle and considered the major cause of human disease. In our study, the TcI strains Colombiana (COL), SylvioX10/4 (SYL), and a cultured clone (TCC) exhibited different biological behavior in a murine model, ranging from high parasitemia and symptomatic cardiomyopathy (SYL), mild parasitemia and high tissue tropism (COL), to no pathogenicity (TCC). Proteomic profiling of the insect (epimastigote) and infective (trypomastigote) forms by two-dimensional gel electrophoresis/matrix-assisted laser desorption ionization-time of flight mass spectrometry, followed by functional annotation of the differential proteome data sets (≥2-fold change, P < 0...

Three new genera of Mimallonidae are described. The monotypic genus Tostallo gen. n. is erected to contain "Perophora" albescens Jones, 1912, which was previously placed in the preoccupied genus Perophora Harris, 1841 and was never formally moved to a valid genus. Perophora is a junior homonym of Cicinnus Blanchard, 1852, but the name albescens is not appropriately placed in Cicinnus due to external and genitalia characteristics entirely unique to the species albescens. The female of Tostallo albescens comb...

Infectious agents are often considered potential triggers of chronic inflammatory disease, including autoimmunity; however, direct evidence is usually lacking. Here we show that following control of acute infection of mice with the myotropic Colombiana strain of Trypanosoma cruzi, parasites persisted in tissue at low levels associated with development of systemic necrotizing vasculitis. Lesions occurred in many but not all organs and tissues, with skeletal muscle arteries being the most severely affected, and were associated with myositis, atrophy, paresis/paralysis, and death...

Arylimidamides (AIAs) have been shown to have considerable biological activity against intracellular pathogens, includingTrypanosoma cruzi, which causes Chagas disease. In the present study, the activities of 12 novel bis-AIAs and 2 mono-AIAs against different strains ofT. cruziin vitroandin vivowere analyzed. The most active wasm-terphenyl bis-AIA (35DAP073), which had a 50% effective concentration (EC50) of 0.5 μM for trypomastigotes (Y strain), which made it 26-fold more effective than benznidazole (Bz; 13 μM)...

High copper (Cu) levels in uprooted old vineyard soils may cause toxicity in transplanted young vines, although such toxicity may be reduced by inoculating plants with arbuscular mycorrhizal fungi (AMF). The objective of this study was to evaluate the effects of AMF on the plant growth, chlorophyll contents, mycorrhizal colonization, and Cu and phosphorus (P) absorption in young vines cultivated in a vineyard soil contaminated by Cu. Commercial vineyard soil with high Cu levels was placed in plastic tubes and transplanted with young vines, which were inoculated with six AMF species (Dentiscutata heterogama, Gigaspora gigantea, Acaulospora morrowiae, A...

Hyptis colombiana is an aromatic shrub native to the Colombian and Venezuelan Andes. Aerial parts were collected in Mérida State at about 3100 m above sea level in February 2005, and May and October 2006. The essential oil was found to contain germacrene D and β-caryophyllene as main constituents (about 50%). The February 2005 and October 2006 oils were found to have antibacterial activity against Staphylococcus aureus, but not the May 2006 oil, probably due to the lack of some minor constituent.

Trypomastigote forms of Trypanosoma cruzi, the causative agent of Chagas Disease, shed extracellular vesicles (EVs) enriched with glycoproteins of the gp85/trans-sialidase (TS) superfamily and other α-galactosyl (α-Gal)-containing glycoconjugates, such as mucins. Here, purified vesicles from T. cruzi strains (Y, Colombiana, CL-14 and YuYu) were quantified according to size, intensity and concentration. Qualitative analysis revealed differences in their protein and α-galactosyl contents. Later, those polymorphisms were evaluated in the modulation of immune responses (innate and in the chronic phase) in C57BL/6 mice...

Autism spectrum disorders (ASDs) are a range of complex neurodevelopmental conditions principally characterized by dysfunctions linked to mental development. Previous studies have shown that there are more than 1000 genes likely involved in ASD, expressed mainly in brain and highly interconnected among them. We applied whole exome sequencing in Colombian-South American trios. Two missense novel SNVs were found in the same child: ALDH1A3 (RefSeq NM_000693: c.1514T>C (p.I505T)) and FOXN1 (RefSeq NM_003593: c...

OBJECTIVES: To assess the risk of bias of clinical trials published in iberoamerican indexed journals from January 1, 2008 to December 31, 2012. METHODS: We performed a descriptive study based on the clinical trials published from January 1st 2008 to December 31st 2012 in the iberoamerican urological journals. We assessed the risk of bias by the Cochrane tool. We used descriptive statistics in Stata 13 and Revman 5.2 to create the risk of bias graphs within and across studies...

The genus Apocharips is here revised. Three previously described species are considered as valid: Apocharips angelicae Pujade-Villar & Evenhuis, 2002, A. hansoni Menke, 1993, and A. trapezoidea (Hartig, 1841). Apocharips eleaphila (Silvestri, 1915) and A. peraperta (Silvestri, 1915) are synonymyzed with A. trapezoidea. Three new species are here described: Apocharips colombiana Ferrer-Suay & Pujade-Villar n. sp., Apocharips tamanii Paretas-Martinez & Pujade-Villar n. sp. and Apocharips tropicale Ferrer-Suay & Paretas-Martinez n...

Chagas disease is caused by the parasite Trypanosoma cruzi, and it begins with a short acute phase characterized by high parasitemia followed by a life-long chronic phase with scarce parasitism. Cardiac involvement is the most prominent manifestation, as 30% of infected subjects will develop abnormal ventricular repolarization with myocarditis, fibrosis and cardiomyocyte hypertrophy by undefined mechanisms. Nevertheless, follow-up studies in chagasic patients, as well as studies with murine models, suggest that the intensity of clinical symptoms and pathophysiological events that occur during the acute phase of disease are associated with the severity of cardiac disease observed during the chronic phase...
