The objective of this study was to determine the effect of ionizing radiation (IR) exposure of parents on carcinogenesis of the next generation focusing on the epigenetic perspective to clarify the relationship between radiation dose and carcinogenesis in F1 generation SD rats. F1 generations from pregnant rats (F0) who were exposed to gamma rays were divided into three groups according to the dose of radiation: 10 rad, 30 rad, and untreated. They were intraperitoneally injected with 50 mg/kg of diethylnitrosamine (DEN)...

The effective population size (Ne ) is a central factor in determining maintenance of genetic variation. The neutral theory predicts that loss of variation depends on Ne , with less genetic drift in larger populations. We monitored genetic drift in 42 Drosophila melanogaster populations of different adult census population sizes (10, 50 or 500) using pooled RAD sequencing. In small populations, variation was lost at a substantially lower rate than expected. This observation was consistent across two ecological relevant thermal regimes, one stable and one with a stressful increase in temperature across generations...

Fish species exhibit substantial variation in the degree of genetic differentiation between sex chromosome pairs, and therefore offer the opportunity to study the full range of sex chromosome evolution. We used restriction-site associated DNA sequencing (RAD-seq) to study the sex chromosomes of Characidium gomesi, a species with conspicuous heteromorphic ZW/ZZ sex chromosomes. We screened 9863 single-nucleotide polymorphisms (SNPs), corresponding to ~1 marker/100 kb distributed across the genome for sex-linked variation...

Gene flow among incipient species can act as a creative or destructive force in the speciation process, generating variation on which natural selection can act while, potentially, undermining population divergence. The flowering plant genus Carex exhibits a rapid and relatively recent radiation with many species limits still unclear. This is the case with the Iberian Peninsula (Spain and Portugal) endemic C. lucennoiberica, which lay unrecognized within Carex furva until its recent description as a new species...

Antioxidants are known to prevent the reactive oxygen species (ROS)-mediated peroxidative damage to the membrane lipids during hypothermic storage of mammalian spermatozoa. We hypothesized here that ROS also affect the lipid-protein interactions, thereby diminishing the membrane's integrity and proteins' anchorage to the bilayer. Antioxidants prevent these damages by scavenging the ROS. Ejaculates from Patanwadi rams were pooled after subjective evaluation and centrifuged using Percoll(®) . Sperm pellet was resuspended in soya lecithin-Tris-fructose diluent (400 × 10(6)  cells/ml) containing either antioxidants (100 IU/ml catalase + 10 mM reduced glutathione) or no antioxidant...

Background: Isolated malakoplakia of the prostate is a rare inflammatory condition that has been clinically mistaken for prostatic malignancies. The development of Prostate Imaging Reporting and Data System (PI-RADS) classifications, and Prostate Health Index (PHI) has led to more accurate diagnosis of clinically significant disease and stratification of patients that may be at risk of prostate cancer. Case Presentation: We present a case of a 75-year-old male who was on follow-up with our hospital for elevated prostate specific antigen (PSA)...

BACKGROUND: Glycated hemoglobin (HbA1c) is an alternative test used for the diagnosis and monitoring of diabetes in kidney transplant recipients. Immunosuppressive drugs are the most important risk factors related with changes in the glucose metabolism after transplant. It is still unknown if they impact on the variability of HbA1c. We assessed the variability of HbA1c levels in a group of renal transplant recipients without diabetes during the first year after transplant. METHODS: We estimated the variability of HbA1c in a group of 95 Brazilian kidney transplant recipients...

Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among females. However, mammographic diagnosis is sometimes non-conclusive with a Breast imaging Reporting and Data System (Bi-RaDS) result of 0. Cancer antigen 15-3 (CA15-3) is the most widely used serum tumor marker for breast cancer screening. Platelet distribution width (PDW) is an early indicator of platelet activation. Fibrinogen contributed to angiogenesis and distant metastasis. The aim of this study was to investigate the ability of CA15-3, PDW, and fibrinogen individually or in combination, to distinguish breast cancer from benign breast disease...

The small GTP-binding protein Rad (RRAD, Ras associated with diabetes) is the founding member of the RGK (Rad, Rem, Rem2, and Gem/Kir) family that regulates cardiac voltage-gated Ca(2+) channel function. However, its cellular and physiological functions outside of the heart remain to be elucidated. Here we report that Rad GTPase function is required for normal bone homeostasis in mice, as Rad deletion results in significantly lower bone mass and higher bone marrow adipose tissue (BMAT) levels. Dynamic histomorphometry in vivo and primary calvarial osteoblast assays in vitro demonstrate that bone formation and osteoblast mineralization rates are depressed, while in vitro osteoclast differentiation is increased, in the absence of Rad...

This Letter reports the successful use of feedback from a spin polarization measurement to the revolution frequency of a 0.97  GeV/c bunched and polarized deuteron beam in the Cooler Synchrotron (COSY) storage ring in order to control both the precession rate (≈121  kHz) and the phase of the horizontal polarization component. Real time synchronization with a radio frequency (rf) solenoid made possible the rotation of the polarization out of the horizontal plane, yielding a demonstration of the feedback method to manipulate the polarization...

Perovskite solar cells and fluorescent collectors formed by a dispersion of quantum dots in a transparent solid are paradigmatic devices for photon capture and utilization that involve the coupling of photon displacement, absorption and regeneration. In order to obtain information about the coupled photonic processes in systems involving photon recycling, we analyse the transfer function for modulated outgoing to incoming photon flux. We show the physical features of light-to-light impedance that reveals a trap-limited diffusion of photons coupled with the nonradiative recombination...

Scleractinian corals of the genus Pocillopora (Lamarck, 1816) are notoriously difficult to identify morphologically with considerable debate on the degree to which phenotypic plasticity, introgressive hybridization and incomplete lineage sorting obscure well-defined taxonomic lineages. Here, we used RAD-seq to resolve the phylogenetic relationships among seven species of Pocillopora represented by 15 coral holobiont metagenomic libraries. We found strong concordance between the coral holobiont datasets, reads that mapped to the Pocillopora damicornis (Linnaeus, 1758) transcriptome, nearly complete mitochondrial genomes, 430 unlinked high-quality SNPs shared across all Pocillopora taxa, and a conspecificity matrix of the holobiont dataset...

Pyrenophora teres f. teres is the causal agent of net form net blotch (NFNB) of barley. In order to map the genetics of avirulence/virulence in P. teres f. teres, a fungal population was developed using P. teres f. teres isolates BB25 (Denmark) and FGOH04Ptt-21 (North Dakota, USA) due to these two isolates differing in virulence on several common barley lines. 109 progeny isolates were obtained from the BB25 by FGOH04Ptt-21 cross that were then used for NFNB disease evaluation across eight barley lines, four of which have been used commonly as NFNB differential lines as well as four cultivars commonly used in barley production in the Northern Great Plains...
