Scinax Wagler, 1830 is a species-rich genus of amphibians with relatively few detailed chromosomal reports. In this work, cytogenetic analyses of Scinaxauratus (Wied-Neuwied, 1821) and Scinaxeurydice (Bokermann, 1968) were carried out based on conventional (Giemsa staining, Ag-NOR and C-banding) and cytomolecular (base-specific fluorochrome staining and fluorescence in situ hybridization - FISH...

Cytogenetic studies in birds are still scarce compared to other vertebrates. Woodcreepers (Dendrocolaptidae) are part of a highly specialized group within the Suboscines of the New World. They are forest birds exclusive to the Neotropical region and similar to woodpeckers, at a comparable evolutionary stage. This paper describes for the first time the karyotypes of the Olivaceous and the Narrow...

ABSTRACT Parodontidae is a relatively small group of Neotropical characiform fishes consisting three genera (Apareiodon, Parodon, and Saccodon) with 32 valid species. A vast cytogenetic literature available on Apareiodon but to date, there no data about Saccodon, genus that contains only species trans-Andean distribution. In the present study karyotype S. wagneri was described, based both conve...

The history of histology indicates that there have been significant changes in the techniques used for histological staining through chemical, molecular biology assays and immunological techniques, collectively referred to as histochemistry. Early histologists used the readily available chemicals to prepare tissues for microscopic studies; these laboratory chemicals were potassium dichromate, a...

Sodium butyrate induces basophilic differentiation of HI60 promyelocytic leukemia cells that have been previously passaged in alkaline medium. A factor present in Mo conditioned medium (Mo-CM) acts synergistically with sodium butyrate to promote basophilic maturation in a dose-dependent fashion. The induced HI-60 cells exhibit nuclei at various stages of maturity and cytoplasmic granules staini...

OBJECTIVE This study investigated whether any genomic change occurs in DNA level in ankylosing spondylitis (AS) by measuring sister chromatid exchange (SCE) frequency. METHODS SCE frequency was detected on metaphase chromosomes obtained from peripheral blood lymphocyte cultures in 15 patients diagnosed as having AS. SCE values were also obtained from 15 healthy subjects as a control group. SC...

LD bodies are identified by light microscopy of the specimen obtained after staining with Giemsa or Leishman stain. The sensitivity of splenic aspirate smear is more than 95% and is regarded as the gold standard for the diagnosis of Kala-azar. But the sensitivity of bone marrow smear is only about 60-85% and the procedure is painful whereas splenic aspiration carries the risk of severe hemorrha...

The data augmentation method is known as a helpful technique to generate dataset with large number of images from one small for supervised training in deep learning. However, low validity image recognition was reported recent study on artificial intelligence (AI). This aimed clarify the optimal learning model generation white blood cells (WBCs). Study Design: We conducted three different method...

INTRODUCTION The present study was carried out from March to May 2008, with the aim of evaluating the effectiveness of different techniques for diagnosing Blastocystis hominis in a sample of the population attended at the Biomedicine Laboratory of Feevale University, Novo Hamburgo, Rio Grande do Sul. METHODS On hundred feces samples from children and adults were evaluated. After collection, t...

The present study aims to investigate the pharmacological effect of the exopolysaccharides from Aphanothece halophytica GR02 (EPSAH) on the HeLa human cervical cancer cell line. HeLa cells were cultured in RPMI-1640-10% FBS medium containing with or without different concentrations of EPSAH. Cell viability was assessed by methylthiazol tetrazolium (MTT) assay. Cell apoptosis was elevated with W...
