Antioxidants safeguard telomeres in bold chicks.

ABSTRACT: Telomeres are sensitive to damage induced by oxidative stress, and thus it is expected that dietary antioxidants may support the maintenance of telomere length in animals, particularly those with a fast rate of life (e.g. fast metabolism, activity and growth). We tested experimentally the effect of antioxidant supplements on telomere length during early development in wild gull chicks with natural individual variations in behaviour pattern and growth rate. Proactive chicks had shorter telomeres than reactive chicks, but the penalty for the bold behaviour pattern was reduced by antioxidant supplementation. Chicks growing faster had longer telomeres during early growth, suggesting that inherited quality supports a fast life history.

Gull chicks grow faster but lose telomeres when prenatal cues mismatch the real presence of sibling competitors.

Project description:During embryonic life, individuals should adjust their phenotype to the conditions that they will encounter after birth, including the social environment, if they have access to (social) cues that allow them to forecast future conditions. In birds, evidence indicates that embryos are sensitive to cues from clutch mates, but whether embryos adjust their development to cope with the expected level of sibling competition has not hitherto been investigated. To tackle this question, we performed a 'match versus mismatch' experimental design where we manipulated the presence of clutch mates (i.e. clutch size manipulation) and the real (postnatal) level of sibling competition (i.e. brood size manipulation) in the yellow-legged gull (Larus michahellis). We provide evidence that the prenatal cues of sibling presence induced developmental changes (such as epigenetic profiles) that had programming effects on chick begging behaviour and growth trajectories after hatching. While receiving mismatching information favoured chick begging and growth, this came at the cost of reduced antioxidant defences and a premature loss of telomeres. Our findings highlight the role of the prenatal social environment in developmental plasticity and suggest that telomere attrition may be an important physiological cost of phenotype-environment mismatch.

The Biomarkers of Lupus Disease Study (BOLD)

Project description:Objectives: Molecular medicine raised expectations for strategically targeted biologics in systemic lupus erythematosus (SLE), but clinical trials have been disappointing and difficult to interpret. Most studies add investigational agents to various, often effective, standard of care (SoC) immunosuppressants used at baseline, with unknown treatment interactions. Eliminating polypharmacy in trials of active lupus patients remains controversial. The BOLD study tested immunosuppressant withdrawal as a novel approach to interpretable SLE trials. Methods: In 41 patients with active, non-organ threatening SLE flare (Group A), temporary steroids were given while background immunosuppressants were withdrawn. Time to loss of disease suppression (“flare”) and safety were evaluated; SoC was immediately resumed when symptoms recurred. Immunologic impacts of SoC treatments were studied at baseline by multiplex assay, ELISA, and mRNA array in Group A plus 62 additional patients donating a single sample (Group B). Results: Patients with lower or higher baseline disease had median times-to-flare of 71 or 45 days, respectively; 98% (40/41) flared by six months. All flares were treated and resolved within six weeks. No serious adverse events occurred from flare or infection. Type I interferon, TH17, and BLyS pathways tracked together. Baseline immunosuppressants had distinct impacts on TH17 and BLyS, depending on interferon signature. Conclusion: Trials in active, non-organ-threatening SLE can safely withdraw background treatments if patients who flare are designated non-responders and returned to SoC. Immunologic effects of SoC vary between interferon-defined subsets. These findings provide a strategy for minimizing or optimizing treatment combinations in lupus trials and clinical care.

Granulysin: killer lymphocyte safeguard against microbes.

Project description:Primary T cell immunodeficiency and HIV-infected patients are plagued by non-viral infections caused by bacteria, fungi, and parasites, suggesting an important and underappreciated role for T lymphocytes in controlling microbes. Here, we review recent studies showing that killer lymphocytes use the antimicrobial cytotoxic granule pore-forming peptide granulysin, induced by microbial exposure, to permeabilize cholesterol-poor microbial membranes and deliver death-inducing granzymes into these pathogens. Granulysin and granzymes cause microptosis, programmed cell death in microbes, by inducing reactive oxygen species and destroying microbial antioxidant defenses and disrupting biosynthetic and central metabolism pathways required for their survival, including protein synthesis, glycolysis, and the Krebs cycle.

Baseline BOLD correlation predicts individuals' stimulus-evoked BOLD responses.

Project description:To investigate whether individuals' ongoing neuronal activity at resting state can affect their response to brain stimulation, fMRI BOLD signals were imaged from the human visual cortex of fifteen healthy subjects in the absence and presence of visual stimulation. It was found that the temporal correlation strength but not amplitude of baseline BOLD signal fluctuations acquired under the eyes-fixed condition is positively correlated with the amplitude of stimulus-evoked BOLD responses across subjects. Moreover, the spatiotemporal correlations of baseline BOLD signals imply a coherent network covering the visual system, which is topographically indistinguishable from the "resting-state visual network" observed under the eyes-closed condition. The overall findings suggest that the synchronization of ongoing brain activity plays an important role in determining stimulus-evoked brain activity even at an early stage of the sensory system. The tight relationship between baseline BOLD correlation and stimulus-evoked BOLD amplitude provides an essential basis for understanding and interpreting the large inter-subject BOLD variability commonly observed in numerous fMRI studies and potentially for improving group fMRI analysis. This study highlights the importance to integrate the information from both resting-state coherent networks and task-evoked neural responses for a better understanding of how the brain functions.

A digital mask to safeguard patient privacy.

Project description:The storage of facial images in medical records poses privacy risks due to the sensitive nature of the personal biometric information that can be extracted from such images. To minimize these risks, we developed a new technology, called the digital mask (DM), which is based on three-dimensional reconstruction and deep-learning algorithms to irreversibly erase identifiable features, while retaining disease-relevant features needed for diagnosis. In a prospective clinical study to evaluate the technology for diagnosis of ocular conditions, we found very high diagnostic consistency between the use of original and reconstructed facial videos (κ ≥ 0.845 for strabismus, ptosis and nystagmus, and κ = 0.801 for thyroid-associated orbitopathy) and comparable diagnostic accuracy (P ≥ 0.131 for all ocular conditions tested) was observed. Identity removal validation using multiple-choice questions showed that compared to image cropping, the DM could much more effectively remove identity attributes from facial images. We further confirmed the ability of the DM to evade recognition systems using artificial intelligence-powered re-identification algorithms. Moreover, use of the DM increased the willingness of patients with ocular conditions to provide their facial images as health information during medical treatment. These results indicate the potential of the DM algorithm to protect the privacy of patients' facial images in an era of rapid adoption of digital health technologies.

Calibrated bold fMRI with an optimized ASL-BOLD dual-acquisition sequence.

Project description:Calibrated fMRI techniques estimate task-induced changes in the cerebral metabolic rate of oxygen (CMRO2) based on simultaneous measurements of cerebral blood flow (CBF) and blood-oxygen-level-dependent (BOLD) signal changes evoked by stimulation. To determine the calibration factor M (corresponding to the maximum possible BOLD signal increase), BOLD signal and CBF are measured in response to a gas breathing challenge (usually CO2 or O2). Here we describe an ASL dual-acquisition sequence that combines a background-suppressed 3D-GRASE readout with 2D multi-slice EPI. The concatenation of these two imaging sequences allowed separate optimization of the acquisition for CBF and BOLD data. The dual-acquisition sequence was validated by comparison to an ASL sequence with a dual-echo EPI readout, using a visual fMRI paradigm. Results showed a 3-fold increase in temporal signal-to-noise ratio (tSNR) of the ASL time-series data while BOLD tSNR was similar to that obtained with the dual-echo sequence. The longer TR of the proposed dual-acquisition sequence, however, resulted in slightly lower T-scores (by 30%) in the BOLD activation maps. Further, the potential of the dual-acquisition sequence for M-mapping on the basis of a hypercapnia gas breathing challenge and for quantification of CMRO2 changes in response to a motor activation task was assessed. In five subjects, an average gray matter M-value of 8.71±1.03 and fractional changes of CMRO2 of 12.5±5% were found. The new sequence remedies the deficiencies of prior combined BOLD-ASL acquisition strategies by substantially enhancing perfusion tSNR, which is essential for accurate BOLD calibration.

Transcriptome profiling of cardiomyocytes treated with antioxidants

Project description:Despite clinical advancement, ischemia-induced myocardial diseases remain an underlying cause of death among individuals throughout the world. Interestingly, we found that the administration of antioxidants can protect cardiomyocytes during ischemia. However, the mechanism involved in inducing the cytoprotective effect under ischemic conditions is not fully elucidated. In this study, we carried out RNA-sequencing data analysis of rat ventricular cardiomyocytes under normoxic, ischemic, and ischemia with eugenol. The RNA sequencing data ascertained that the ischemic condition differentially regulated 7,694 genes in the NRVCs compared to the normoxic condition (padj<0.05). Out of 7,694 genes, 3,774 genes were up-regulated, and 3,920 genes were down-regulated. Also, the administration of eugenol in the presence of ischemic condition up-regulated 159 genes and down-regulated 111 genes. Functional enrichment analysis of differentially regulated genes was carried out using clusterProfiler R and ingenuity pathway analysis. In this study, we found that both the up-regulated and down-regulated genes regulated the post-translational modification of histone proteins during ischemia. Also, the up-regulated genes controlled cell death and survival, protein synthesis and transport etc. The down-regulated genes controlled cellular growth and development, cell signaling, cellular assembly and organization, cellular movement, cellular respiration, and cell death and survival. It was found that eugenol administration under ischemic conditions up-regulated intracellular transduction signaling and down-regulated negative regulation of the metabolic process, negative regulation of nucleic acid templated transcription, and negative regulation of the biosynthetic process. All in all, the administration of antioxidants improves cell survival via down-regulating negative regulation of biosynthetic processes.
