Arachis; Genome, Plant; Karyotype; Phylogeny; Polymorphism, Genetic; Principal component analysis

Arachis kuhlmannii occurs in Mato Grosso and Mato Grosso do Sul States, Brazil. Its area of occurrence partially overlaps with that of other species in the Arachis section. Because of their morphological similarities, these species are often mistaken one for another. This study aimed the correct classification of available accessions as Arachis kuhlmannii, or other species, and the ... more

Double aneuploidy is considered a rare phenomenon. Herein, we describe a case of double aneuploidy 48,XXY,+21 in a neonate with congenital heart defects. The 28-day-old neonate male (23-year-old mother and 24-year-old father) was admitted to a neonatal intensive care unit owing to congenital heart disease. Echocardiography showed a complete atrioventricular septal defect with Rastelli type B ... more

Chromosomal alterations; Karyotype; Myelodysplastic syndrome; Phenotypes

Myelodysplastic syndrome (MDS), an onco-hematological disease, is characterized by distinct levels of peripheral blood cytopenia, cell differentiation dysplasia and various types of chromosomal alterations. The Revised International Prognostic Scoring System uses the GTG-banding karyotype as one of the main components for scoring patient prognosis in MDS. Using GTG ... more

AZFc; Infertility; Karyotype; Sox9 gene; SRY

Sex differentiation in males is a highly complex phenomenon based on synergistic interactions between genes and their coded proteins. The Sox9 gene plays a critical role in embryonic development, cell lineages, and stem cell maintenance during testicular development. Sox9 gene expression is associated with sex reversal, with a 46, XX karyotype in males and ... more

cytotaxonomy; Karyotype; Symphurus; Tonguefishes

The family Cynoglossidae (tonguefishes) is a speciose group of Pleuronectiformes, encompassing about 20% of described species in this order, distributed among three genera (Cynoglossus, Paraplagusia and Symphurus). Symphurus is the only genus of tonguefish in the Western Atlantic, being characterized by species complexes and cryptic forms ... more

Chromosomal sex; Determination of sex; Karyotype; Multiplex fluorescent PCR; Sex chromosomal abnormalities

Quantitative PCR puts great demands on DNA quality and relies on a comparison of fragment amplification between two chromosomes using different primers. The use of a single primer pair capable of reliable relative comparative amplification would be a great advantage.  Using this approach, we developed a rapid, high-throughput, semi-automated and cost-efficient ... more

Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were ... more

This study aimed to investigate the predictability of a phenotype when using a dynamic model of cattle growth. Genotypic and phenotypic information on Nellore (Bos indicus) cattle were used in a genome-wide association analysis designed to contrast the biological interpretation of core parameters [conversion efficiency of metabolizable energy to net energy for gain (k) and adjusted final ... more

Rubus coriifolius Focke is a wild plant from the Rosaceae family. It grows in both Guatemala and Mexico. The polar extract of the aerial parts of this plant has antibacterial, anti-inflammatory, and anti-protozoal activities. These properties may explain the traditional use of this plant. In vivo and in vitro assays were used to assess the genotoxic and toxic effects of an ethanol extract of ... more

Myostatin (MSTN) is expressed in the myotome and developing skeletal muscles, and acts to regulate the number of muscle fibers. Wuding chicken large body, developed muscle, high disease resistance, and tender, delicious meat, and are not selected for fast growth. Broiler chickens (Avian broiler) are selected for fast growth and have a large body size and high muscle mass. Here, 240 one-day-old ... more
