Abstract
The generation, manipulation and quantification of non-classical light, such as quantum-entangled photon pairs, differs significantly from methods with classical light. Thus, quantum measures could be harnessed to give new information about the interaction of light with matter. In this study we investigate if quantum entanglement can be used to diagnose disease. In particular, we test whether brain tissue from subjects suffering from Alzheimer's disease can be distinguished from healthy tissue. We find that this is indeed the case. Polarization-entangled photons traveling through brain tissue lose their entanglement via a decohering scattering interaction that gradually renders the light in a maximally mixed state. We found that in thin tissue samples (between 120 and 600 micrometers) photons decohere to a distinguishable lesser degree in samples with Alzheimer's disease than in healthy-control ones. Thus, it seems feasible that quantum measures of entangled photons could be used as a means to identify brain samples with the neurodegenerative disease.

Abstract
3129 Background: The impact of common or rare gene mutations on the sensitivity of cancers to ionizing radiation remains largely unknown. We conducted a systematic, arrayed (single variant per well) profiling effort to identify gene mutations that alter cellular sensitivity to radiation and validated some of our findings using a clinical cohort of patients who received thoracic radiotherapy alone. Methods: Candidate mutations were prioritized on the basis of genotype-phenotype associations from our previously completed large-scale cancer cell line irradiation profiling study (doi: 10.1038/ncomms11428), location within conserved protein domains, and functional impact (MutationAssessor). We used site-directed mutagenesis to generate mutant clones (2 clones per variant) and transferred the ORFs into lentiviral vectors in SV40 lung primary immortalized cells (BEAS2B). For clinical validation, an IRB-approved study was used to identify patients treated with lung radiotherapy alone. 197 patients with primary (stage I–IV) or recurrent lung cancer and patients with other cancer types and solitary metastases or oligometastases to the lung were included. Death without evidence of local failure was treated as a competing event, and Fine and Gray regression modeling was used to examine potential predictors of local failure. Results: Over 600 cancer variants were tested in ̃1200 experimental replicates, comprising 91 genes. We identified known and new radioresistant and radiosensitive variants involved in several cellular functional categories including cellular signaling, cytoskeleton, cell cycle, apoptosis, DNA methylation, and DNA repair. Variants that conferred resistance in BEAS2B cells were significantly more likely to confer resistance in TERT-HU1 and NCI-H520 cells, suggesting that most functional variants are cellular context indifferent. Variants under somatic oncogenic selection (hotspot mutants) were significantly more likely to confer resistance to radiation. Several infrequent cancer variants ( < 1% prevalence in cancer), including those in ERBB3, SMAD4, TGFBR1, VHL, CTNNB1, and MAP2K1, conferred radiation resistance. Some genes (e.g. KEAP1) demonstrated significant intragenic allelic variation in the magnitude of conferred resistance and other genes (e.g. CTNNB1) displayed both resistance and sensitivity in a protein domain-dependent manner. KRAS (resistant; HR 2.23; P= 0.02) and CTNNB1 exon 3 (sensitive; HR 0.3; P = 0.04) mutants conferred resistance and sensitivity, respectively, to radiotherapy in our clinical cohort. Conclusions: We report on a large-scale profiling effort to identify mutant alleles that govern radiation survival. Our results reveal new insights into potentially actionable determinants of tumor sensitivity to radiotherapy and accelerate clinical validation of common and rare gene mutations that impact radiation sensitivity.

Abstract
Effective therapies for non-small cell lung cancer (NSCLC) remain challenging despite an increasingly comprehensive understanding of somatically altered oncogenic pathways. It is now clear that therapeutic agents with potential to impact the tumor immune microenvironment potentiate immune-orchestrated therapeutic benefit. Herein, we evaluated the immunoregulatory properties of histone deacetylase (HDAC) and bromodomain inhibitors, two classes of drugs that modulate the epigenome, with a focus on key cell subsets that are engaged in an immune response. By evaluating human peripheral blood and NSCLC tumors, we show that the selective HDAC6 inhibitor ricolinostat promotes phenotypic changes that support enhanced T-cell activation and improved function of antigen-presenting cells. The bromodomain inhibitor JQ1 attenuated CD4+FOXP3+ T regulatory cell suppressive function and synergized with ricolinostat to facilitate immune-mediated tumor growth arrest, leading to prolonged survival of mice with lung adenocarcinomas. Collectively, our findings highlight the immunomodulatory effects of two epigenetic modifiers that, together, promote T cell-mediated antitumor immunity and demonstrate their therapeutic potential for treatment of NSCLC.Significance: Selective inhibition of HDACs and bromodomain proteins modulates tumor-associated immune cells in a manner that favors improved T-cell function and reduced inhibitory cellular mechanisms. These effects facilitated robust antitumor responses in tumor-bearing mice, demonstrating the therapeutic potential of combining these epigenetic modulators for the treatment of NSCLC.

Abstract
In 2007, 17 years after the first reported Mediterranean epizootic of striped dolphins (Stenella coeruleoalba), a new strain of the morbillivirus caused the deaths of dozens of striped dolphins that appeared dead on Western Mediterranean beaches. DDT and PCB levels were determined in these dolphins, and in individuals from sporadic strandings in the surrounding years. Comparison between the two epidemic events showed that organochlorine (OC) levels in the dolphins from 1990 epizootic were more than 10-fold higher for tPCB and 6-fold higher for tDDT than levels in dolphins from the 2007 outbreak. In contrast to what occurred in 1990, OCs from individuals affected by the second outburst fit well with curves of OC trends in the Mediterranean. Because the virulence of the 2007 epizootic was much lower, and the deceased dolphins affected by it did not present OC concentrations that were more elevated than in presumably healthy individuals, this second outburst is not believed to have been enhanced by OC pollutants.
