The potential mutagenic and genotoxic effects of the herbicide atrazine were investigated in different developmental stages of Dendropsophus minutus tadpoles. These animals were exposed to 4 nominal concentrations of atrazine (2.25, 4.5, 9, and 18 mg/L) and 40 mg/L of Cyclophosphamide as a positive control, for 96 h. Negative controls were also added to the experiment. The tadpoles were divided into three groups according to Gosner's developmental stages, namely GS 25-33 as premetamorphic, GS 36-39 as prometamorphic, and GS 42-43 as metamorphic climax...

Triatoma sherlocki Papa, Jurberg, Carcavallo, Cerqueira & Barata was described in 2002, based on specimens caught in the wild in the municipality of Gentio do Ouro, Bahia, Brazil. In 2009, nymphs and adults were detected inside homes and sylvatic specimens were positive for Trypanosoma cruzi (Chagas). No information on the bionomics of T. sherlocki exists, although such data are considered essential to estimate its vector and colonization potential in domestic environments. Herein, the biological cycle of T...

Amyloid precursor protein (APP) is essential to physiological processes such as synapse formation and neural plasticity. Sequential proteolysis of APP by beta- and gamma-secretases generates amyloid-beta peptide (Aβ), the main component of senile plaques in Alzheimer Disease. Alternative APP cleavage by alpha-secretase occurs within Aβ domain, releasing soluble α-APP (sAPPα), a neurotrophic fragment. Among other functions, sAPPα is important to synaptogenesis, neural survival and axonal growth. APP and sAPPα levels are increased in models of neuroplasticity, which suggests an important role for APP and its metabolites, especially sAPPα, in the rearranging brain...

Glyphosate-based herbicides are widely used in agricultural systems. Although the target organism are particularly plant organisms, there are numerous studies showing adverse effects in aquatic animals, such as inhibition of acetyl cholinesterase, effects on kidney, liver, and gill and stressors effects. This study analyzed the effects of commercial formulation of glyphosate on feeding behavior in Pacu (Piaractus mesopotamicus). Fish were exposed to three glyphosate concentrations (0.2, 0.6, and 1.8 ppm) for 15 days...

Following the creation of the Brazilian Unified National Health System (SUS), the Brazilian Health Informatics Department (DATASUS) was established in 1991, aimed at organizing information systems and databases in health. Online data access and viewing is free and open, using tables and graphs of aggregate data and access to raw data. However, the current form of data access does not fully meet the demands by health system administrators and other users for a flexible, user-friendly tool that allows dealing with various relevant health issues in the knowledge search and decision-making...

INTRODUCTION: Endovascular aneurysm repair (EVAR) has progressively expanded to more complex anatomies, frequently outside manufacturer's instructions for use (IFU). However, the long term results of off-label use of EVAR remain largely undocumented. The aim of this paper is to examine the long term results of outside IFU EVAR. EVIDENCE ACQUISITION: English literature was searched to identify publications on long term results for outside IFU EVAR. A follow-up extending for at least 5 years was the minimum required as inclusion criteria...
