Extensive sampling and citizen science expand the distribution of the threatened freshwater turtle Ranacephala hogei (Mertens, 1967).

Ranacephala hogei is a South American freshwater turtle considered one of the 25 most endangered chelonian species in the world. Endemic to the Atlantic Forest hotspot of southeastern Brazil, the conservation status of R. hogei is subject to continuous assessment at various levels.

Characteristics of the Integument of Phyllomedusa burmeisteri (Anura, Phyllomedusidae) and Boana semilineata (Anura, Hylidae) Males Can Contribute to Understanding its Relation to Habitat.

The integument of anurans plays vital physiological roles, crucial for understanding the species' survival in their environment. Despite its significance, there are few studies describing the cutaneous morphology of anurans from the Brazilian Atlantic Forest. This study aimed to characterize the integument of Phyllomedusa burmeisteri and Boana semilineata in males using microscopic and histochemical approaches.

Chromosome Evolution in the Genus Partamona (Apidae: Meliponini), with Comments on B Chromosome Origin.

The genus Partamona includes 33 species of stingless bees, of which 11 were studied cytogenetically. The main goal of this study was to propose a hypothesis about chromosomal evolution in Partamona by combining molecular and cytogenetic data. Cytogenetic analyses were performed on 3 Partamona species.

[Partial cross-cultural adaptation of the Aberrant Behavior Checklist (ABC) scale for analysis of patients with mental retardation].

The aim of the ABC (Aberrant Behavior Checklist) is to evaluate the treatment response for aberrant behavior in patients with mental retardation. The aim of this study was to describe the partial cross-cultural adaptation of the ABC scale to Brazilian Portuguese. The process included conceptual and item equivalence, two translations (T1, T2) and their back-translations (R1, R2), evaluation of referential and general equivalence, expert evaluations, a pre-test, and elaboration of the final version.

Frequency of symptoms of attention deficit and hyperactivity disorder in autistic children.

Background: Both DSM-IV and the ICD-10 exclude diagnosis of attention deficit/hyperactivity disorder (ADHD) when autism diagnostic is present. Some authors suggest, however, that autism can be associated to other comorbidity amongst which the ADHD.

Objective: To estimate prevalence of ADHD in children with autism.

Control of psychomotor agitation and aggressive behavior in patients with autistic disorder: a retrospective chart review.

Objective: To evaluate the efficacy of pharmacotherapy on the symptoms of psychomotor agitation and aggressive behavior in a sample of patients with autistic spectrum disorder.

Method: The charts of all patients with a diagnosis of autistic spectrum disorder, receiving care for psychomotor agitation and/or aggressive behavior in two psychiatric outpatient departments between 2001 and 2006, were reviewed. The Clinical Global Impression-Severity and -Improvement scales (CGI-S and CGI-I) were applied to the data retrieved from the charts.
