Accumulation of glycine (GLY) is the biochemical hallmark of glycine encephalopathy (GE), an aminoacidopathy characterized by severe neurological dysfunction that may lead to early death. In the present study, we evaluated the effect of a single intracerebroventricular administration of GLY on bioenergetics, redox homeostasis, and histopathology in brain of(More)
Patients affected by sulfite oxidase (SO) deficiency present severe seizures early in infancy and progressive neurological damage, as well as tissue accumulation of sulfite, thiosulfate and S-sulfocysteine. Since the pathomechanisms involved in the neuropathology of SO deficiency are still poorly established, we evaluated the effects of sulfite on redox(More)
The genus Paramaka Savage & Domínguez, 1992 (Ephemeroptera: Leptophlebiidae) is restricted to South America, and it is comprised of four species. The male imago of P. incognita is described for the first time based on material from the state of Roraima in northern Brazil.

New records of Leptohyphidae for Northeastern Brazil are provided. Previously, only Tricorythopsis bahiensis Dias, Salles & Ferreira had been recorded in this region, but we now record one species of Amanahyphes Salles & Molineri, one of Leptohyphes Eaton, three of Traverhyphes Molineri, three of Tricorythodes Ulmer, and seven of Tricorythopsis Traver. Two(More)
The genus Camelobaetidius Demoulin, 1966 has 38 species distributed throughout the Neotropical Region, being one of the most studied genera of the family Baetidae. Based on material from Brazil, the aim of the present paper is to describe five new species of Camelobaetidius with the terminal filament as long as cerci, and to redescribe the nymph of C.(More)
The genus Caenis Stephens, 1835 is well represented in South America with 24 recorded species (14 in Brazil). Based on additional material from Brazil, we describe for the first time the nymphal and egg stages of C. reissi, and re-describe the eggs of C. cuniana. New distributional records for these species and Caenis elidioi are given, and C. teipunensis(More)
The monotypic genus Corinnella Thomas & Dominique, 2006, was described based on nymphs from French Guyana, and since the original description nothing has been added to knowledge of its systematics. The aim of the present paper is to describe a new species of the genus from Northern Brazil, to improve its diagnoses, and to report the genus for the first time(More)
The genus Camelobaetidius Demoulin, 1966 has 39 species distributed throughout the Nearctic and Neotropical Regions, being one of the most studied genera of the family Baetidae. Based on material from Brazil, the aim of the present paper is to describe adults of C. janae Dominique & Thomas, 2001 and C. yacutinga Nieto, 2003, and to recognize a new synonym(More)
The genus Lumahyphes Molineri, 2004 (Ephemeroptera: Leptohyphidae) currently is comprised of three species. Lumahyphes cocal sp. nov. is described based on material from the state of Roraima in northern Brazil. The new species differs from the other described species by having the following combination of characteristics: greyish wing membrane; terga base(More)
The male imago of Americabaetis longetron Lugo-Ortiz & McCafferty is described based on nymphs reared on field in the municipality Alfredo Chaves, Espírito Santo state, Brazil. The species can be distinguished from the others male imagos of the genus by the following combination of characters: 1) turbinate eyes uniformly separated from each other, upper(More)
