Two new land planarian species (Platyhelminthes: Tricladida) from the Cerrado biome in southwestern Brazil.

Most Neotropical land flatworm species are known from areas of the Atlantic Forest. Herein, we describe two new land planarian species from areas of semideciduous forest in the Cerrado biome in southwestern Brazil. Paraba aurantia Marques & Leal-Zanchet, sp.

Coming out in a harsh environment: a new genus and species for a land flatworm (Platyhelminthes: Tricladida) occurring in a ferruginous cave from the Brazilian savanna.

Faunal inventories in ferruginous caves from an area belonging to the Brazilian savanna (Cerrado phytophysiognomy), on the eastern margin of the Serra do Espinhaço Plateau, in southeastern Brazil, have revealed the occurrence of land flatworms. Herein, a flatworm sampled in such subterranean environment is described as a new genus and species of the Neotropical subfamily Geoplaninae, gen. nov.

Integrative approach reveals two new species of Obama (Platyhelminthes: Tricladida) from the South-Brazilian Atlantic Forest.

The genus Obama Carbayo et al., 2013 includes 38 species, being the most species-rich within Geoplaninae. Species of this genus show a similar anatomy regarding their copulatory apparatus, which may hinder species differentiation.

Searching for shelter in a ferruginous cave? A new species of from a plateau in the Brazilian savanna (Platyhelminthes, Tricladida).

In a fauna survey in the eastern margin of Serra do Espinhaço Plateau, in an area belonging to the Brazilian savanna (Cerrado phytophysiognomy), a land flatworm was sampled in a ferruginous cave. Anatomical and histological analyses indicated that it belongs to a new species of the genus , which is herein described. The new species shows an almost homogenous dark brown dorsal pigmentation, eyes spreading over the dorsal surface, a collar-shaped pharynx, and a prostatic vesicle with two portions separated by a canal.

Tomographic imaging of fragmented cortical bone heteroimplant and methylmethacrylate in segmental bone defect of rabbit tibia.

Purpose: To evaluate the performance of composites consisting of fragmented cortical bone heteroimplant in association with methylmethacrylate preserved in 98% glycerin, in segmental bone defect of rabbit tibia medial metaphysis.

Methods: In this study were used twelve adult New Zealand rabbits, divided into three groups of four animals each: G30 (30 days), G60 (60 days) and G90 (90 days). The bone defects previously created in the tibia were filled with composites and both were evaluated by cone-beam computed tomography, immediately after surgery and after 30, 60, and 90 days.

Prevalence of impacted teeth in a Brazilian subpopulation.

The objective of this study was to estimate the prevalence of impacted teeth in a subpopulation of Brazilian patients based on the retrospective analysis of panoramic radiographs obtained at an oral radiology clinic. Out of 1,977 panoramic radiographs, 1,352 fulfilled inclusion criteria, and 22,984 teeth were assessed. Data were statistically analyzed using Kolmogorov-Smirnov's and Levene's tests; significance was set at 5%.
