Chagas disease and triatomine biology (Heteroptera, Triatominae), with emphasis on aspects of spermatogenesis

R. Silistino-SouzaDOI: http://dx.doi.org/10.4238/vol10-3ta039 ABSTRACT A century after the discovery of Chagas disease, it is still one of the most important parasitic diseases affecting humans. The subfamily Triatominae is important in medical health because these insects are vectors of Trypanosoma cruzi, the etiologic agent of Chagas disease. These insects are also of important cytological relevance because […]

Classical and molecular cytogenetic analysis in Chelonoidis carbonaria and Phrynops geoffroanus (Testudines)

C.E.S. ZagoDOI: http://dx.doi.org/10.4238/vol10-3ta038 ABSTRACT The number of species of reptiles has decreased since the time that they ruled the Earth until the present days. Turtles have been little studied, particularly regarding their cytogenetics. The present study investigated, using classical and molecular cytogenetic techniques, the chromosomes of Chelonoidis carbonaria, a terrestrial species, and Phrynops geoffroanus, an […]

Influence of δβ-thalassemia or regulatory elements in individuals with increased fetal Hb levels in the São Paulo northwest population

G.C.S. Carrocini and C.R. Bonini-DomingosDOI: http://dx.doi.org/10.4238/vol10-3ta035 ABSTRACT Fetal hemoglobin (Hb F), formed by two alpha globin chains (α) and two gamma chains (γ) (α2 γ2), has reduced expression in adults, ranging from 0 to 1% of total hemoglobin. Increased levels of Hb F are due to mutations in the β-globin family, which cause hereditary persistence […]

Le(a-b-) phenotype: potential risk factor forinfection by the RH strain of Toxoplasmagondii in pregnancy

F. Nakashima The Lewis histo-blood group system is characterized by the expression of the Lea and Leb antigens in the gastrointestinal tract, whose synthesis results in interactions between α2-L-fucosyltransferase (FUTII) and α3/4-L-fucosyltransferase (FUTIII) enzymes coded by the FUT2 (19q.13.3) and FUT3 (19p13.3) genes. FUTII and FUTIII fucosylate the type 1 oligosaccharide precursor (Galβ1→3NAcGlcβ1→3-R) at distinct […]

Gene expression and nutrient utilization in the basideomycete Moniliophthora perniciosa suggest the existence of regulatory mechanisms of catabolite repression

I.S. Ganda Moniliophthora perniciosa, a hemibiotrophic fungus (characterized by biotrophic and saprotrophic phases in its life cycle), is the causal agent of witches’ broom disease (WBD), which negatively affects the Latin American cocoa (Theobroma cacao) production. The southern region of Bahia, in Brazil, had the first occurrence of WBD in 1989, which led to a […]
