Calcium (Ca) and potassium (K) are essential nutrients in animal nutrition. Furthermore, the Ca content can influence meat tenderness because it is needed by proteolytic system of calpains calpastatins, major factors postmortem tenderization skeletal muscles. K content, which for muscle contraction, also affect tenderness. This study showed that positively affects Warner-Bratzler shear force (WBSF), measured at 14days aging, means higher levels related to lower Additionally, a significant...
Beef cattle require dietary minerals for optimal health, production and reproduction. Concentrations of in tissues are at least partly genetically determined. Mapping genomic regions that affect the mineral content bovine longissimus dorsi muscle can contribute to identification genes control balance, transportation, absorption excretion could be associated metabolic disorders. We applied a genome-wide association strategy genotyped 373 Nelore steers from 34 half-sib families with Illumina...
Iron (Fe) is an essential mineral for metabolism and plays a central role in range of biochemical processes. Therefore, this study aimed to identify differentially expressed (DE) genes metabolic pathways Longissimus dorsi (LD) muscle from cattle with divergent iron content, as well investigate the likely these DE biological processes underlying beef quality parameters. Samples RNA extraction sequencing iron, copper, manganese, zinc determination were collected LD muscles at slaughter. Eight...
Abstract Mineral content affects the biological processes underlying beef quality. Muscle mineral concentration depends not only on intake-outtake balance and muscle type, but also age, environment, breed, genetic factors. To unveil factors involved in concentration, we applied a pairwise differential gene expression analysis groups of Nelore steers genetically divergent for nine different concentrations. Here, based significant differences between contrasting groups, presented candidate...
Abstract Mineral contents in bovine muscle can affect meat quality, growth, health, and reproductive traits. To better understand the genetic basis of this phenotype Nelore ( Bos indicus) cattle, we analysed genome-wide mRNA miRNA expression data from 114 samples. The analysis implemented a new application for two complementary algorithms: partial correlation information theory (PCIT) regulatory impact factor (RIF), which included estimated genomic breeding values (GEBVs) phenotypes...
Epigenetic repression has been linked to the regulation of different cell states. In this study, we focus on influence repression, mainly by H3K27me3, over gene expression in muscle cells, which may affect mineral content, a phenotype that is relevant function and beef quality. Based inverse relationship between H3K27me3 (i.e., epigenetic repression) contrasting sample groups, computationally predicted regulatory genes content. To end, applied TRIAGE predictive method followed rank product...
TICK RESIDUES.Experimental procedures based on factorial design and surface response methodology were applied to establishe experimental conditions for the decomposition of a 1:400 (v/v) Supocade ® (chlorfenvinphos 13.8% cypermethrin 2.6%) solution, used control cattle ticks.Experiments exploring photo-oxidative reactions performed with without UV radiation, fixing exposition time pesticide volume, varying oxidant mixture.The use 3.6 mmol L -1 Fe 2+ plus 1.9 mol H 2 O radiation provided...
Introduction Real-time polymerase chain reaction (RT-qPCR) is an important tool for analyzing gene expression. However, before the expression of target genes, it crucial to normalize reference in order find most stable be used as endogenous control. A that remains all samples under different treatments considered a suitable normalizer. In this sense, we aimed identify genes normalization heart and liver tissues from two genetically divergent groups chickens (Cobb 500® commercial line Peloco...
Abstract Mineral amount in bovine muscle affect meat quality, growth, health and reproductive traits beef cattle. To better understand the genetic basis of this phenotype, we implemented new applications use for two complementary algorithms: partial correlation information theory (PCIT) regulatory impact factor (RIF), by including GEBVs as part input. We used PCIT to determine putative relationships based on significant associations between gene expression mineral amount. Then, RIF was genes...
Spatial and intra-annual variation of foraminifera biogeochemical indicators in the Real estuary, northern coast Bahia, Brazil. The aim this research was to carry out characterization using seasonal physical-chemical, sedimentological, geochemical data. During rainy season were obtained 324 foreheads (Jul/2013), with Trochammina inflata abundance (75.85%). In April campaign, 298 found 10 sampling points, especially T. (40.60%), Quinqueloculina lamarckiana (9.73%), Ammonia tepida (8.05%)...
