Mitochondrial DNA (mtDNA) copy number is an important component of mitochondrial function and varies with age, disease, and environmental factors. We aimed to determine whether mtDNA copy number varies with habitual differences in sleep duration within pairs of monozygotic twins. Academic clinical research center. 15 sleep duration discordant monozygotic twin pairs (30 twins, 80% female; mean age 42.1 years [SD 15.0]). Sleep duration was phenotyped with wrist actigraphy. Each twin pair included a "normal" (7-9 h/24) and "short" (sleeping twin. Fasting peripheral blood leukocyte DNA was assessed for mtDNA copy number via the n-fold difference between qPCR measured mtDNA and nuclear DNA creating an mtDNA measure without absolute units. We used generalized estimating equation linear regression models accounting for the correlated data structure to assess within-pair effects of sleep duration on mtDNA copy number. Mean within-pair sleep duration difference per 24 hours was 94.3 minutes (SD 62.6 min). We found reduced sleep duration (β = 0.06; 95% CI 0.004, 0.12; P sleep efficiency (β = 0.51; 95% CI 0.06, 0.95; P sleep duration was associated with a decrease in mtDNA copy number of 0.06. Likewise, a 1% decrease in actigraphy-defined sleep efficiency was associated with a decrease in mtDNA copy number of 0.51. Reduced sleep duration and sleep efficiency were associated with reduced mitochondrial DNA copy number in sleep duration discordant monozygotic twins offering a potential mechanism whereby short sleep impairs health and longevity through mitochondrial stress. © 2015 Associated Professional Sleep Societies, LLC.

The widespread clinical implementation of gene therapy requires the ability to stably integrate genetic information through gene transfer vectors in a safe, effective, and economical manner. The latest generation of Sleeping Beauty (SB) transposon vectors fulfills these requirements, and may overcome limitations associated with viral gene transfer vectors and transient nonviral gene delivery approaches that are prevalent in ongoing clinical trials. The SB system enables high-level stable gene transfer and sustained transgene expression in multiple primary human somatic cell types, thereby representing a highly attractive gene transfer strategy for clinical use. Here, we review the most important aspects of using SB for gene therapy, including vectorization as well as genomic integration features. We also illustrate the path to successful clinical implementation by highlighting the application of chimeric antigen receptor (CAR)-modified T cells in cancer immunotherapy.

Remobilization of Sleeping Beauty transposons in the germline of Xenopus tropicalis

Directory of Open Access Journals (Sweden)

Yergeau Donald A

2011-11-01

Full Text Available Abstract Background The Sleeping Beauty (SB transposon system has been used for germline transgenesis of the diploid frog, Xenopus tropicalis. Injecting one-cell embryos with plasmid DNA harboring an SB transposon substrate together with mRNA encoding the SB transposase enzyme resulted in non-canonical integration of small-order concatemers of the transposon. Here, we demonstrate that SB transposons stably integrated into the frog genome are effective substrates for remobilization. Results Transgenic frogs that express the SB10 transposase were bred with SB transposon-harboring animals to yield double-transgenic 'hopper' frogs. Remobilization events were observed in the progeny of the hopper frogs and were verified by Southern blot analysis and cloning of the novel integrations sites. Unlike the co-injection method used to generate founder lines, transgenic remobilization resulted in canonical transposition of the SB transposons. The remobilized SB transposons frequently integrated near the site of the donor locus; approximately 80% re-integrated with 3 Mb of the donor locus, a phenomenon known as 'local hopping'. Conclusions In this study, we demonstrate that SB transposons integrated into the X. tropicalis genome are effective substrates for excision and re-integration, and that the remobilized transposons are transmitted through the germline. This is an important step in the development of large-scale transposon-mediated gene- and enhancer-trap strategies in this highly tractable developmental model system.

Oxidative DNA damage may be increased among nightshift workers because of suppression of melatonin, a cellular antioxidant, and/or inflammation related to sleep disruption. However, oxidative DNA damage has received limited attention in previous studies of nightshift work. From two previous cross-sectional studies, urine samples collected during a night sleep period for 217 dayshift workers and during day and night sleep (on their first day off) periods for 223 nightshift workers were assayed for 8-hydroxydeoxyguanosine (8-OH-dG), a marker of oxidative DNA damage, using high-performance liquid chromatography with electrochemical detection. Urinary measures of 6-sulfatoxymelatonin (aMT6s), a marker of circulating melatonin levels, and actigraphy-based sleep quality data were also available. Nightshift workers during their day sleep periods excreted 83% (p=0.2) and 77% (p=0.03) of the 8-OH-dG that dayshift workers and they themselves, respectively, excreted during their night sleep periods. Among nightshift workers, higher aMT6s levels were associated with higher urinary 8-OH-dG levels, and an inverse U-shaped trend was observed between 8-OH-dG levels and sleep efficiency and sleep duration. Reduced excretion of 8-OH-dG among nightshift workers during day sleep may reflect reduced functioning of DNA repair machinery, which could potentially lead to increased cellular levels of oxidative DNA damage. Melatonin disruption among nightshift workers may be responsible for the observed effect, as melatonin is known to enhance repair of oxidative DNA damage. Quality of sleep may similarly impact DNA repair. Cellular levels of DNA damage will need to be evaluated in future studies to help interpret these findings.

Is it time to awaken Sleeping Beauty? European psychiatry has been sleeping since 1980.

Science.gov (United States)

de Leon, Jose

2014-01-01

The Diagnostic and Statistical Manual of Mental Disorders (DSM-III), published in 1980, has led to a dead end, the DSM-V. Following the allegory of Sleeping Beauty, the DSM-III put European psychiatry to sleep; it now must wake up to create a 21st century psychiatric language for descriptive psychopathology and psychiatric nosology. Four topics are reviewed. First, the review of descriptive psychopathology focuses on: a) Chaslin's and Jaspers's books, and b) Schneider's transmittal of Jaspers's ideas and involvement with Kraepelin in incorporating neuroscience into psychiatric nosology. Second, US psychiatry's historic steps include: a) the pseudoscience of psychoanalysis, b) the low level of pre-DSM-III diagnostic expertise, c) the neo-Kraepelinian revolution which led to DSM-III, d) the failure to improve diagnostic skills, and e) the reprise of Kraepelin's marketing ("neuroscience will save psychiatry"). Third, the DSM-III devastated European psychiatry by destroying: a) the national textbooks which increased consistency but eliminated creative European thinking; and b) the Arbeitsgemenschaft fur Methodic und Dokumentation in der Psychiatrie, the most reasonable attempt to reach diagnostic agreement: start with symptoms/signs (first level) rather than disorders (second level). Fourth, Berrios elaborated upon Jaspers, who described psychiatry as a hybrid science and heterogeneous. Berrios affirmed that psychiatric symptoms/signs are hybrid. Some symptoms are in the "semantic space" and cannot be "explained" by neuroscience. Copyright © 2013 SEP y SEPB. Published by Elsevier España. All rights reserved.

Kokol, Peter; Blažun Vošner, Helena; Vermeulen, Joeri

Sleeping Beauties (SBs) are publications that are scarcely cited in the years immediately following publication but then suddenly become highly cited later. Such publications have unique citation patterns and can reveal important developments in the field in which they appear. No holistic analysis of nursing SBs has been done yet. The aim of this study was to identify and analyze the SB phenomenon in the nursing research literature. The corpus for the nursing SB identification was harvested from the Web of Science Core Collection (Thomas Reuters) for the period 1934-2015. Citation histories of 212,239 publications were screened. From those, 3,209 publications with more than 100 citations were selected for analysis. We used our own software and applied the van Raan (2004) and Baumgartner (2010) criteria for SBs-a 5-year sleeping period with at most 10 citations during that time, an average of at least five citations per year after the first 10 years, with at least 100 citations in total. The knowledge context for SBs was determined using citing papers. All citing papers were analyzed with the help of VOSviewer software. Nine publications were identified as SBs (prevalence of 0.004%). The length of sleep duration ranged from 5 to 10 years (M = 6.8, SD = 2.0), depth of sleep ranged from 0.2 to 0.8 citations (M = 0.6, SD = 0.2), and awake intensity ranged from 6.4 to 15.0 citations (M = 11.0, SD = 3.8). The average number of citations to SBs was 229. Most nursing SBs were produced in the United States (n = 8) from top institutions in journals with high-impact factors. Nursing SBs covered topics including resilience, sampling in qualitative research, metasynthesis, postoperative pain in children, dementia rating scales, care of patients with Alzheimer's disease, nursing theory related to fatigue mechanisms in cancer patients, and family participation during resuscitation. Nursing SBs were cited by authors from a large number of institutions and countries; the number of

The aim of this study was to evaluate overall genetic damage induced by total sleep deprivation in obese, female Zucker rats of differing ages. Lean and obese Zucker rats at 3, 6, and 15 months old were randomly distributed into two groups for each age group: home-cage control and sleep-deprived (N = 5/group). The sleep-deprived groups were deprived sleep by gentle handling for 6 hours, whereas the home-cage control group was allowed to remain undisturbed in their home-cage. At the end of the sleep deprivation period, or after an equivalent amount of time for the home-cage control groups, the rats were brought to an adjacent room and decapitated. The blood, brain, and liver tissue were collected and stored individually to evaluate DNA damage. Significant genetic damage was observed only in 15-month-old rats. Genetic damage was present in the liver cells from sleep-deprived obese rats compared with lean rats in the same condition. Sleep deprivation was associated with genetic damage in brain cells regardless of obesity status. DNA damage was observed in the peripheral blood cells regardless of sleep condition or obesity status. Taken together, these results suggest that obesity was associated with genetic damage in liver cells, whereas sleep deprivation was associated with DNA damage in brain cells. These results also indicate that there is no synergistic effect of these noxious conditions on the overall level of genetic damage. In addition, the level of DNA damage was significantly higher in 15-month-old rats compared to younger rats.

The aim of this investigation was to evaluate genetic damage induced in male rats by experimental sleep loss for short-term (24 and 96 h) and long-term (21 days) intervals, as well as their respective recovery periods in peripheral blood, brain, liver and heart tissue by the single cell gel (comet) assay. Rats were paradoxically deprived of sleep (PSD) by the platform technique for 24 or 96 h, or chronically sleep-restricted (SR) for 21 days. We also sought to verify the time course of their recovery after 24 h of rebound sleep. The results showed DNA damage in blood cells of rats submitted to PSD for 96 h. Brain tissue showed extensive genotoxic damage in PSD rats (both 24 and 96 h), though the effect was more pronounced in the 96 h group. Rats allowed to recover from the PSD-96 h and SR-21 days treatments showed DNA damage as compared to negative controls. Liver and heart did not display any genotoxicity activity. Corticosterone concentrations were increased after PSD (24 and 96 h) relative to control rats, whereas these levels were unaffected in the SR group. Collectively, these findings reveal that sleep loss was able to induce genetic damage in blood and brain cells, especially following acute exposure. Since DNA damage is an important step in events leading to genomic instability, this study represents a relevant contribution to the understanding of the potential health risks associated with sleep deprivation.

Is better beautiful or is beautiful better? Exploring the relationship between beauty and category structure.

Sanders, Megan; Davis, Tyler; Love, Bradley C

We evaluate two competing accounts of the relationship between beauty and category structure. According to the similarity-based view, beauty arises from category structure such that central items are favored due to their increased fluency. In contrast, the theory-based view holds that people's theories of beauty shape their perceptions of categories. In the present study, subjects learned to categorize abstract paintings into meaningfully labeled categories and rated the paintings' beauty, value, and typicality. Inconsistent with the similarity-based view, beauty ratings were highly correlated across conditions despite differences in fluency and assigned category structure. Consistent with the theory-based view, beautiful paintings were treated as central members for categories expected to contain beautiful paintings (e.g., art museum pieces), but not in others (e.g., student show pieces). These results suggest that the beauty of complex, real-world stimuli is not determined by fluency within category structure but, instead, interacts with people's prior knowledge to structure categories.

ON BEAUTY AND THE BEAUTIFUL IN AESTHETIC EDUCATION

2013-06-01

Full Text Available We titled our work “On Beauty and the Beautiful in Aesthetic Education” and we analyzed the category beautiful in function of better understanding the issues of aesthetic education.The basic point was the fact that the determination of the term beautiful is being different in both, time aspect and space aspect. Also, the authors involved in this matter have got different understanding on beautiful issue, on its essence, on its role in human development and on the development of the aesthetics and the aesthetic education.Therefore, within our work, there is an attempt to differ the approaches towards the category beautiful, to comment it, to compare it and finally to give our approach.

Somatic mutagenesis with a Sleeping Beauty transposon system leads to solid tumor formation in zebrafish.

Maura McGrail

2011-04-01

Full Text Available Large-scale sequencing of human cancer genomes and mouse transposon-induced tumors has identified a vast number of genes mutated in different cancers. One of the outstanding challenges in this field is to determine which genes, when mutated, contribute to cellular transformation and tumor progression. To identify new and conserved genes that drive tumorigenesis we have developed a novel cancer model in a distantly related vertebrate species, the zebrafish, Danio rerio. The Sleeping Beauty (SB T2/Onc transposon system was adapted for somatic mutagenesis in zebrafish. The carp ß-actin promoter was cloned into T2/Onc to create T2/OncZ. Two transgenic zebrafish lines that contain large concatemers of T2/OncZ were isolated by injection of linear DNA into the zebrafish embryo. The T2/OncZ transposons were mobilized throughout the zebrafish genome from the transgene array by injecting SB11 transposase RNA at the 1-cell stage. Alternatively, the T2/OncZ zebrafish were crossed to a transgenic line that constitutively expresses SB11 transposase. T2/OncZ transposon integration sites were cloned by ligation-mediated PCR and sequenced on a Genome Analyzer II. Between 700-6800 unique integration events in individual fish were mapped to the zebrafish genome. The data show that introduction of transposase by transgene expression or RNA injection results in an even distribution of transposon re-integration events across the zebrafish genome. SB11 mRNA injection resulted in neoplasms in 10% of adult fish at ∼10 months of age. T2/OncZ-induced zebrafish tumors contain many mutated genes in common with human and mouse cancer genes. These analyses validate our mutagenesis approach and provide additional support for the involvement of these genes in human cancers. The zebrafish T2/OncZ cancer model will be useful for identifying novel and conserved genetic drivers of human cancers.

Obstructive Sleep Apnea (OSAS) is a disease associated with the increase of cardiovascular risk and it is characterized by repeated episodes of Intermittent Hypoxia (IH) which inducing oxidative stress and systemic inflammation. Mitochondria are cell organelles involved in the respiratory that have their own DNA (MtDNA). The aim of this study was to investigate if the increase of oxidative stress in OSAS patients can induce also MtDNA alterations. 46 OSAS patients (age 59.27 ± 11.38; BMI 30.84 ± 3.64; AHI 36.63 ± 24.18) were compared with 36 control subjects (age 54.42 ± 6.63; BMI 29.06 ± 4.7; AHI 3.8 ± 1.10). In blood cells Content of MtDNA and nuclear DNA (nDNA) was measured in OSAS patients by Real Time PCR. The ratio between MtDNA/nDNA was then calculated. Presence of oxidative stress was evaluated by levels of Reactive Oxygen Metabolites (ROMs), measured by diacron reactive oxygen metabolite test (d-ROM test). MtDNA/nDNA was higher in patients with OSAS than in the control group (150.94 ± 49.14 vs 128.96 ± 45.8; p = 0.04), the levels of ROMs were also higher in OSAS subjects (329.71 ± 70.17 vs 226 ± 36.76; p = 0.04) and they were positively correlated with MtDNA/nDNA (R = 0.5, p DNA damage induced by the increase of oxidative stress. Intermittent hypoxia seems to be the main mechanism which leads to this process.

Full Text Available Adoptive transfer of T cells expressing a CD19-specific chimeric antigen receptor (CAR is being evaluated in multiple clinical trials. Our current approach to adoptive immunotherapy is based on a second generation CAR (designated CD19RCD28 that signals through a CD28 and CD3-ζ endodomain. T cells are electroporated with DNA plasmids from the Sleeping Beauty (SB transposon/transposase system to express this CAR. Stable integrants of genetically modified T cells can then be retrieved when co-cultured with designer artificial antigen presenting cells (aAPC in the presence of interleukin (IL-2 and 21. Here, we reveal how the platform technologies of SB-mediated transposition and CAR-dependent propagation on aAPC were adapted for human application. Indeed, we have initiated clinical trials in patients with high-risk B-lineage malignancies undergoing autologous and allogeneic hematopoietic stem-cell transplantation (HSCT. We describe the process to manufacture clinical grade CD19-specific T cells derived from healthy donors. Three validation runs were completed in compliance with current good manufacturing practice for Phase I/II trials demonstrating that by 28 days of co-culture on γ-irradiated aAPC ∼10(10 T cells were produced of which >95% expressed CAR. These genetically modified and propagated T cells met all quality control testing and release criteria in support of infusion.

Dad's Snoring May Have Left Molecular Scars in Your DNA: the Emerging Role of Epigenetics in Sleep Disorders.

The sleep-wake cycle is a biological phenomena under the orchestration of neurophysiological, neurochemical, neuroanatomical, and genetical mechanisms. Moreover, homeostatic and circadian processes participate in the regulation of sleep across the light-dark period. Further complexity of the understanding of the genesis of sleep engages disturbances which have been characterized and classified in a variety of sleep-wake cycle disorders. The most prominent sleep alterations include insomnia as well as excessive daytime sleepiness. On the other side, several human diseases have been linked with direct changes in DNA, such as chromatin configuration, genomic imprinting, DNA methylation, histone modifications (acetylation, methylation, ubiquitylation or sumoylation, etc.), and activating RNA molecules that are transcribed from DNA but not translated into proteins. Epigenetic theories primarily emphasize the interaction between the environment and gene expression. According to these approaches, the environment to which mammals are exposed has a significant role in determining the epigenetic modifications occurring in chromosomes that ultimately would influence not only development but also the descendants' physiology and behavior. Thus, what makes epigenetics intriguing is that, unlike genetic variation, modifications in DNA are altered directly by the environment and, in some cases, these epigenetic changes may be inherited by future generations. Thus, it is likely that epigenetic phenomena might contribute to the homeostatic and/or circadian control of sleep and, possibly, have an undescribed link with sleep disorders. An exciting new horizon of research is arising between sleep and epigenetics since it represents the relevance of the study of how the genome learns from its experiences and modulates behavior, including sleep.

Beauty Requires Thought.

Science.gov (United States)

Brielmann, Aenne A; Pelli, Denis G

2017-05-22

The experience of beauty is a pleasure, but common sense and philosophy suggest that feeling beauty differs from sensuous pleasures such as eating or sex. Immanuel Kant [1, 2] claimed that experiencing beauty requires thought but that sensuous pleasure can be enjoyed without thought and cannot be beautiful. These venerable hypotheses persist in models of aesthetic processing [3-7] but have never been tested. Here, participants continuously rated the pleasure felt from a nominally beautiful or non-beautiful stimulus and then judged whether they had experienced beauty. The stimuli, which engage various senses, included seeing images, tasting candy, and touching a teddy bear. The observer reported the feelings that the stimulus evoked. The time course of pleasure, across stimuli, is well-fit by a model with one free parameter: pleasure amplitude. Pleasure amplitude increases linearly with the feeling of beauty. To test Kant's claim of a need for thought, we reduce cognitive capacity by adding a "two-back" task to distract the observer's thoughts. The distraction greatly reduces the beauty and pleasure experienced from stimuli that otherwise produce strong pleasure and spares that of less-pleasant stimuli. We also find that strong pleasure is always beautiful, whether produced reliably by beautiful stimuli or just occasionally by sensuous stimuli. In sum, we confirm Kant's claim that only the pleasure associated with feeling beauty requires thought and disprove his claim that sensuous pleasures cannot be beautiful.

Human papillomavirus type 16 (HPV16) is the etiologic factor for cervical cancer and a subset of oropharyngeal cancers. Although several prophylactic HPV vaccines are available, no effective therapeutic strategies to control active HPV diseases exist. Tumor implantation models are traditionally used to study HPV-associated buccal tumors. However, they fail to address precancerous phases of disease progression and display tumor microenvironments distinct from those observed in patients. Previously, K14-E6/E7 transgenic mouse models have been used to generate spontaneous tumors. However, the rate of tumor formation is inconsistent, and the host often develops immune tolerance to the viral oncoproteins. We developed a preclinical, spontaneous, HPV16 + buccal tumor model using submucosal injection of oncogenic plasmids expressing HPV16-E6/E7, NRas G12V , luciferase, and sleeping beauty (SB) transposase, followed by electroporation in the buccal mucosa. We evaluated responses to immunization with a pNGVL4a-CRT/E7(detox) therapeutic HPV DNA vaccine and tumor cell migration to distant locations. Mice transfected with plasmids encoding HPV16-E6/E7, NRas G12V , luciferase, and SB transposase developed tumors within 3 weeks. We also found transient anti-CD3 administration is required to generate tumors in immunocompetent mice. Bioluminescence signals from luciferase correlated strongly with tumor growth, and tumors expressed HPV16-associated markers. We showed that pNGVL4a-CRT/E7(detox) administration resulted in antitumor immunity in tumor-bearing mice. Lastly, we demonstrated that the generated tumor could migrate to tumor-draining lymph nodes. Our model provides an efficient method to induce spontaneous HPV + tumor formation, which can be used to identify effective therapeutic interventions, analyze tumor migration, and conduct tumor biology research.

The sense of beauty.

Hagman, George

2002-06-01

This paper proposes an integrative psychoanalytic model of the sense of beauty. The following definition is used: beauty is an aspect of the experience of idealisation in which an object(s), sound(s) or concept(s) is believed to possess qualities of formal perfection. The psychoanalytic literature regarding beauty is explored in depth and fundamental similarities are stressed. The author goes on to discuss the following topics: (1) beauty as sublimation: beauty reconciles the polarisation of self and world; (2) idealisation and beauty: the love of beauty is an indication of the importance of idealisation during development; (3) beauty as an interactive process: the sense of beauty is interactive and intersubjective; (4) the aesthetic and non-aesthetic emotions: specific aesthetic emotions are experienced in response to the formal design of the beautiful object; (5) surrendering to beauty: beauty provides us with an occasion for transcendence and self-renewal; (6) beauty's restorative function: the preservation or restoration of the relationship to the good object is of utmost importance; (7) the self-integrative function of beauty: the sense of beauty can also reconcile and integrate self-states of fragmentation and depletion; (8) beauty as a defence: in psychopathology, beauty can function defensively for the expression of unconscious impulses and fantasies, or as protection against self-crisis; (9) beauty and mortality: the sense of beauty can alleviate anxiety regarding death and feelings of vulnerability. In closing the paper, the author offers a new understanding of Freud'semphasis on love of beauty as a defining trait of civilisation. For a people not to value beauty would mean that they cannot hope and cannot assert life over the inevitable and ubiquitous forces of entropy and death.

Despite an established link between sleep deprivation and epigenetic processes in humans, it remains unclear to what extent sleep deprivation modulates DNA methylation. We performed a within-subject randomized blinded study with 16 healthy subjects to examine the effect of one night of total sleep deprivation (TSD) on the genome-wide methylation profile in blood compared with that in normal sleep. Genome-wide differences in methylation between both conditions were assessed by applying a paired regression model that corrected for monocyte subpopulations. In addition, the correlations between the methylation of genes detected to be modulated by TSD and gene expression were examined in a separate, publicly available cohort of 10 healthy male donors (E-GEOD-49065). Sleep deprivation significantly affected the DNA methylation profile both independently and in dependency of shifts in monocyte composition. Our study detected differential methylation of 269 probes. Notably, one CpG site was located 69 bp upstream of ING5, which has been shown to be differentially expressed after sleep deprivation. Gene set enrichment analysis detected the Notch and Wnt signaling pathways to be enriched among the differentially methylated genes. These results provide evidence that total acute sleep deprivation alters the methylation profile in healthy human subjects. This is, to our knowledge, the first study that systematically investigated the impact of total acute sleep deprivation on genome-wide DNA methylation profiles in blood and related the epigenomic findings to the expression data.

Propionic acid is used primarily as a food preservative with smaller applications as a chemical building block for the production of many products including fabrics, cosmetics, drugs, and plastics. Biological production using propionibacteria would be competitive against chemical production through hydrocarboxylation of ethylene if native producers could be engineered to reach near-theoretical yield and good productivity. Unfortunately, engineering propionibacteria has proven very challenging. It has been suggested that activation of the sleeping beauty operon in Escherichia coli is sufficient to achieve propionic acid production. Optimising E. coli production should be much easier than engineering propionibacteria if tolerance issues can be addressed. Propionic acid is produced in E. coli via the sleeping beauty mutase operon under anaerobic conditions in rich medium via amino acid degradation. We observed that the sbm operon enhances amino acids degradation to propionic acid and allows E. coli to degrade isoleucine. However, we show here that the operon lacks an epimerase reaction that enables propionic acid production in minimal medium containing glucose as the sole carbon source. Production from glucose can be restored by engineering the system with a methylmalonyl-CoA epimerase from Propionibacterium acidipropionici (0.23 ± 0.02 mM). 1-Propanol production was also detected from the promiscuous activity of the native alcohol dehydrogenase (AdhE). We also show that aerobic conditions are favourable for propionic acid production. Finally, we increase titre 65 times using a combination of promoter engineering and process optimisation. The native sbm operon encodes an incomplete pathway. Production of propionic acid from glucose as sole carbon source is possible when the pathway is complemented with a methylmalonyl-CoA epimerase. Although propionic acid via the restored succinate dissimilation pathway is considered a fermentative process, the engineered pathway

Is moral beauty different from facial beauty? Two functional magnetic resonance imaging experiments were performed to answer this question. Experiment 1 investigated the network of moral aesthetic judgments and facial aesthetic judgments. Participants performed aesthetic judgments and gender judgments on both faces and scenes containing moral acts. The conjunction analysis of the contrasts ‘facial aesthetic judgment > facial gender judgment’ and ‘scene moral aesthetic judgment > scene gender judgment’ identified the common involvement of the orbitofrontal cortex (OFC), inferior temporal gyrus and medial superior frontal gyrus, suggesting that both types of aesthetic judgments are based on the orchestration of perceptual, emotional and cognitive components. Experiment 2 examined the network of facial beauty and moral beauty during implicit perception. Participants performed a non-aesthetic judgment task on both faces (beautiful vs common) and scenes (containing morally beautiful vs neutral information). We observed that facial beauty (beautiful faces > common faces) involved both the cortical reward region OFC and the subcortical reward region putamen, whereas moral beauty (moral beauty scenes > moral neutral scenes) only involved the OFC. Moreover, compared with facial beauty, moral beauty spanned a larger-scale cortical network, indicating more advanced and complex cerebral representations characterizing moral beauty. PMID:25298010

Value, like beauty, exists in the eye of the beholder. This article places the value of clinical sleep medicine services in historical context and presents a vision for the value-based sleep of the future. First, the history of value and payment in sleep medicine is reviewed from the early days of the field, to innovative disruption, to the widespread adoption of home sleep apnea testing. Next, the importance of economic perspective is discussed, with emphasis on cost containment and cost-shifting between payers, employers, providers, and patients. Specific recommendations are made for sleep medicine providers and the field at large to maximize the perceived value of sleep. Finally, alternate payment models and value-based care are presented, with an eye toward the future for clinical service providers as well as integrated health delivery networks. © 2018 American Academy of Sleep Medicine.

Contribution of sleep to the repair of neuronal DNA double-strand breaks: evidence from flies and mice.

Exploration of a novel environment leads to neuronal DNA double-strand breaks (DSBs). These DSBs are generated by type 2 topoisomerase to relieve topological constrains that limit transcription of plasticity-related immediate early genes. If not promptly repaired, however, DSBs may lead to cell death. Since the induction of plasticity-related genes is higher in wake than in sleep, we asked whether it is specifically wake associated with synaptic plasticity that leads to DSBs, and whether sleep provides any selective advantage over wake in their repair. In flies and mice, we find that enriched wake, more than simply time spent awake, induces DSBs, and their repair in mice is delayed or prevented by subsequent wake. In both species the repair of irradiation-induced neuronal DSBs is also quicker during sleep, and mouse genes mediating the response to DNA damage are upregulated in sleep. Thus, sleep facilitates the repair of neuronal DSBs.

The Sleeping Beauty transposon (SB-Tn) system is being used widely as a DNA vector for the delivery of therapeutic transgenes, as well as a tool for the insertional mutagenesis in animal models. In order to accurately assess the insertional potential and properties related to the integration of SB it is essential to determine the copy number of SB-Tn in the host genome. Recently developed SB100X transposase has demonstrated an integration rate that was much higher than the original SB10 and that of other versions of hyperactive SB transposases, such as HSB3 or HSB17. In this study, we have constructed a series of SB vectors carrying either a DsRed or a human β-globin transgene that was encompassed by cHS4 insulator elements, and containing the SB100X transposase gene outside the SB-Tn unit within the same vector in cis configuration. These SB-Tn constructs were introduced into the K-562 erythroid cell line, and their presence in the genomes of host cells was analyzed by Southern blot analysis using non-radioactive probes. Many copies of SB-Tn insertions were detected in host cells regardless of transgene sequences or the presence of cHS4 insulator elements. Interestingly, the size difference of 2.4 kb between insulated SB and non-insulated controls did not reflect the proportional difference in copy numbers of inserted SB-Tns. We then attempted methylation-sensitive Southern blots to assess the potential influence of cHS4 insulator elements on the epigenetic modification of SB-Tn. Our results indicated that SB100X was able to integrate at multiple sites with the number of SB-Tn copies larger than 6 kb in size. In addition, the non-radioactive Southern blot protocols developed here will be useful to detect integrated SB-Tn copies in any mammalian cell type.

The ability to experience aesthetics plays a fundamental role in human social interactions, as well as the capacity to feel empathy. Some studies have shown that beauty perception shares part of the neural network underlying emotional and empathic abilities, which are also known to affect sleep quality and duration. In this study, we evaluated for the first time the effects of sleep on the relation between aesthetic perception and empathic abilities in healthy subjects using a mediation analysis approach. One-hundred and twenty-six subjects participated in this study. One-hundred and one subjects slept at home (Sleep Group). The remaining 25 subjects were tested as controls after 1 night of sleep deprivation to assess the effects of lack of sleep on aesthetic perception and empathy (Sleep-Deprived Group). All participants underwent one testing session in which they performed a battery of empathy tests and an aesthetic perception task (Golden Beauty). The results showed that sleep duration mediates the relationship between empathy and aesthetic perception in the sleep group. The mediation effect of sleep was more evident on the emotional empathy measures. Conversely, in the sleep deprivation group the lack of correlations among empathy, aesthetic perception and sleep variables did not allow to perform the mediation analysis. These results suggest that adequate sleep duration may play a significant role in improving cognitive and emotional empathic abilities as well as the capability to give accurate aesthetic judgements. © 2018 European Sleep Research Society.

Long-Term PEDF Release in Rat Iris and Retinal Epithelial Cells after Sleeping Beauty Transposon-Mediated Gene Delivery

Full Text Available Pigment epithelium derived factor (PEDF is a potent antiangiogenic, neurotrophic, and neuroprotective molecule that is the endogenous inhibitor of vascular endothelial growth factor (VEGF in the retina. An ex vivo gene therapy approach based on transgenic overexpression of PEDF in the eye is assumed to rebalance the angiogenic-antiangiogenic milieu of the retina, resulting in growth regression of choroidal blood vessels, the hallmark of neovascular age-related macular degeneration. Here, we show that rat pigment epithelial cells can be efficiently transfected with the PEDF-expressing non-viral hyperactive Sleeping Beauty transposon system delivered in a form free of antibiotic resistance marker miniplasmids. The engineered retinal and iris pigment epithelium cells secrete high (141 ± 13 and 222 ± 14 ng PEDF levels in 72 hr in vitro. In vivo studies showed cell survival and insert expression during at least 4 months. Transplantation of the engineered cells to the subretinal space of a rat model of choroidal neovascularization reduces almost 50% of the development of new vessels.

The purpose of the present study was to characterize the genetic damage induced by paradoxical sleep deprivation (PSD) in combination with cocaine or ecstasy (3,4-methylenedioxymethamphetamine; MDMA) in multiple organs of male mice using the single cell gel (comet) assay. C57BL/6J mice were submitted to PSD by the platform technique for 72 hours, followed by drug administration and evaluation of DNA damage in peripheral blood, liver and brain tissues. Cocaine was able to induce genetic damage in the blood, brain and liver cells of sleep-deprived mice at the majority of the doses evaluated. Ecstasy also induced increased DNA migration in peripheral blood cells for all concentrations tested. Analysis of damaged cells by the tail moment data suggests that ecstasy is a genotoxic chemical at the highest concentrations tested, inducing damage in liver or brain cells after sleep deprivation in mice. Taken together, our results suggest that cocaine and ecstasy/MDMA act as potent genotoxins in multiple organs of mice when associated with sleep loss.

Germline transgenic pigs by Sleeping Beauty transposition in porcine zygotes and targeted integration in the pig genome.

Directory of Open Access Journals (Sweden)

Wiebke Garrels

Full Text Available Genetic engineering can expand the utility of pigs for modeling human diseases, and for developing advanced therapeutic approaches. However, the inefficient production of transgenic pigs represents a technological bottleneck. Here, we assessed the hyperactive Sleeping Beauty (SB100X transposon system for enzyme-catalyzed transgene integration into the embryonic porcine genome. The components of the transposon vector system were microinjected as circular plasmids into the cytoplasm of porcine zygotes, resulting in high frequencies of transgenic fetuses and piglets. The transgenic animals showed normal development and persistent reporter gene expression for >12 months. Molecular hallmarks of transposition were confirmed by analysis of 25 genomic insertion sites. We demonstrate germ-line transmission, segregation of individual transposons, and continued, copy number-dependent transgene expression in F1-offspring. In addition, we demonstrate target-selected gene insertion into transposon-tagged genomic loci by Cre-loxP-based cassette exchange in somatic cells followed by nuclear transfer. Transposase-catalyzed transgenesis in a large mammalian species expands the arsenal of transgenic technologies for use in domestic animals and will facilitate the development of large animal models for human diseases.

Sleep deprivation is associated with impaired immune responses, cancer, and morbidity and mortality, and can degrade cognitive performance, although individual differences exist in such responses. Sleep deprivation induces DNA strand breaks and DNA base oxidation in animals, and psychological stress is associated with increased DNA damage in humans. It remains unknown whether sleep deprivation or psychological stress in humans affects DNA damage response from environmental stressors, and whether these responses predict cognitive performance during sleep deprivation. Sixteen healthy adults (ages 29-52;mean age±SD, 36.4±7.1 years;7 women) participated in a 5-day experiment involving two 8 hour time-in-bed [TIB] baseline nights, followed by 39 hours total sleep deprivation (TSD), and two 8-10 hour TIB recovery nights. A modified Trier Social Stress Test was conducted on the day after TSD. Psychomotor Vigilance Tests measured behavioral attention. DNA damage was assessed in blood cells collected at 5 time points, and blood cells were irradiated ex-vivo. TSD, alone or in combination with psychological stress, did not induce significant increases in DNA damage. By contrast, radiation-induced DNA damage decreased significantly in response to TSD, but increased back to baseline when combined with psychological stress. Cognitively-vulnerable individuals had more radiation-induced DNA strand breaks before TSD, indicating their greater sensitivity to DNA damage from environmental stressors. Our results provide novel insights into the molecular consequences of sleep deprivation, psychological stress, and performance vulnerability. They are important for situations involving sleep loss, radiation exposure and cognitive deficits, including cancer therapy, environmental toxicology, and space medicine.

American society's feminine ideal has consistently emphasized youth as beauty and getting old as ugly. Feeling unattractive produces several intrapsychic conflicts leading to depression and anxiety. Summary of the literature on beauty and aging, beauty and culture, and theories of physical beauty will be presented. With a clinical example of a female patient, the writer investigates the conscious and unconscious fantasies, conflicts, and sense of self inside and outside that impelled a physically beautiful female patient to bring her own body closer to her perception of idealized beauty with the aid of plastic surgery.

Beauty production at CDF

2008-01-01

A review of recent measurements of beauty production, based on proton antiproton collision data at √s = 1.96 TeV and using the CDF detector, is given. Previous measurements of beauty (b) quark production at the Tevatron, carried out at centre-of-mass energies √s = 1.8 TeV, have shown discrepancies when compared to Next to Leading Order (NLO) predictions [1]. Improved predictions and experimental procedures have reduced this discrepancy [2]. Improved parton density functions, better fragmentation functions and more complete theoretical calculations have improved theoretical accuracy. Experimentally, measurements of beauty production at √s = 1.96 TeV are now presented in terms of b hadrons or B mesons, to avoid problems unfolding back to the quark level. In this review [3] measurements of inclusive beauty (where one beauty jet or hadron is reconstructed in the event), and beauty + X (where X can be a boson or another beauty jet or hadron), production will be presented: inclusive beauty jet cross-section; semi and fully reconstructed B meson cross-section; beauty dijet cross-section; semi-reconstructed B B meson cross-section; Z boson + beauty jet cross-section. More information concerning other measurements of heavy quark production can be found elsewhere [4

What are the neural mechanisms underlying beauty based on objective parameters and beauty based on subjective social construction? This study scanned participants with fMRI while they performed aesthetic judgments on concrete pictographs and abstract oracle bone scripts. Behavioral results showed both pictographs and oracle bone scripts were judged to be more beautiful when they referred to beautiful objects and positive social meanings, respectively. Imaging results revealed regions associated with perceptual, cognitive, emotional and reward processing were commonly activated both in beautiful judgments of pictographs and oracle bone scripts. Moreover, stronger activations of orbitofrontal cortex (OFC) and motor-related areas were found in beautiful judgments of pictographs, whereas beautiful judgments of oracle bone scripts were associated with putamen activity, implying stronger aesthetic experience and embodied approaching for beauty were elicited by the pictographs. In contrast, only visual processing areas were activated in the judgments of ugly pictographs and negative oracle bone scripts. Results provide evidence that the sense of beauty is triggered by two processes: one based on the objective parameters of stimuli (embodied natural beauty) and the other based on the subjective social construction (social endowed beauty).

A baculovirus vector is capable of efficiently transducing many nondiving and diving cell types. However, the potential of baculovirus is restricted for many gene delivery applications as a result of the transient gene expression that it mediates. The plasmid-based Sleeping Beauty (SB) transposon system integrates transgenes into target cell genome efficiently with a genomic integration pattern that is generally considered safer than the integration of many other integrating vectors; yet efficient delivery of therapeutic genes into cells of target tissues in vivo is a major challenge for nonviral gene therapy. In the present study, SB was introduced into baculovirus to obtain novel hybrid vectors that would combine the best features of the two vector systems (i.e. effective gene delivery and efficient integration into the genome), thus circumventing the major limitations of these vectors. We constructed and optimized SB-baculovirus hybrid vectors that bear either SB100x transposase or SB transposon in the forward or reverse orientations with respect to the viral backbone The functionality of the novel hybrid vectors was investigated in cell cultures and in a proof-of-concept study in the mouse eye. The hybrid vectors showed high and sustained transgene expression that remained stable and demonstrated no signs of decline during the 2 months follow-up in vitro. These results were verified in the mouse eye where persistent transgene expression was detected two months after intravitreal injection. Our results confirm that (i) SB-baculovirus hybrid vectors mediate long-term gene expression in vitro and in vivo, and (ii) the hybrid vectors are potential new tools for the treatment of ocular diseases.

The aim of this investigation was to evaluate overall DNA damage induced by experimental paradoxical sleep deprivation (PSD) in estrous-cycling and ovariectomized female rats to examine possible hormonal involvement during DNA damage. Intact rats in different phases of the estrous cycle (proestrus, estrus, and diestrus) or ovariectomized female Wistar rats were subjected to PSD by the single platform technique for 96 h or were maintained for the equivalent period as controls in home-cages. After this period, peripheral blood and tissues (brain, liver, and heart) were collected to evaluate genetic damage using the single cell gel (comet) assay. The results showed that PSD caused extensive genotoxic effects in brain cells, as evident by increased DNA migration rates in rats exposed to PSD for 96 h when compared to negative control. This was observed for all phases of the estrous cycle indistinctly. In ovariectomized rats, PSD also led to DNA damage in brain cells. No significant statistically differences were detected in peripheral blood, the liver or heart for all groups analyzed. In conclusion, our data are consistent with the notion that genetic damage in the form of DNA breakage in brain cells induced by sleep deprivation overrides the effects related to endogenous female sex hormones.

Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA), existing in hepatocyte nuclei as a stable minichromosome, plays a central role in the life cycle of the virus and permits the persistence of infection. Despite being essential for HBV infection, little is known about the molecular mechanisms of cccDNA formation, regulation and degradation, and there is no therapeutic agents directly targeting cccDNA, fore mostly due to the lack of robust, reliable and quantifiable HBV cccDNA models. In this study, combined the Cre/loxP and sleeping beauty transposons system, we established HepG2-derived cell lines integrated with 2-60 copies of monomeric HBV genome flanked by loxP sites (HepG2-HBV/loxP). After Cre expression via adenoviral transduction, 3.3-kb recombinant cccDNA (rcccDNA) bearing a chimeric intron can be produced in the nuclei of these HepG2-HBV/loxP cells. The rcccDNA could be accurately quantified by quantitative PCR using specific primers and cccDNA pool generated in this model could be easily detected by Southern blotting using the digoxigenin probe system. We demonstrated that the rcccDNA was epigenetically organized as the natural minichromosome and served as the template supporting pgRNA transcription and viral replication. As the expression of HBV S antigen (HBsAg) is dependent on the newly generated cccDNA, HBsAg is the surrogate marker of cccDNA. Additionally, the efficacies of 3 classes of anti-HBV agents were evaluated in HepG2-HBV/loxP cells and antiviral activities with different mechanisms were confirmed. These data collectively suggested that HepG2-HBV/loxP cell system will be powerful platform for studying cccDNA related biological mechanisms and developing novel cccDNA targeting drugs.

Sleep loss reduces the DNA-binding of BMAL1, CLOCK, and NPAS2 to specific clock genes in the mouse cerebral cortex.

Directory of Open Access Journals (Sweden)

Using chromatin immunoprecipitation (ChIP, we first showed that, as reported for the liver, DNA-binding of CLOCK and BMAL1 to target clock genes changes in function of time-of-day in the cerebral cortex. Tissue extracts were collected at ZT0 (light onset, -6, -12, and -18, and DNA enrichment of E-box or E'-box containing sequences was measured by qPCR. CLOCK and BMAL1 binding to Cry1, Dbp, Per1, and Per2 depended on time-of-day, with maximum values reached at around ZT6. We then observed that SD, performed between ZT0 and -6, significantly decreased DNA-binding of CLOCK and BMAL1 to Dbp, consistent with the observed decrease in Dbp mRNA levels after SD. The DNA-binding of NPAS2 and BMAL1 to Per2 was also decreased by SD, although SD is known to increase Per2 expression in the cortex. DNA-binding to Per1 and Cry1 was not affected by SD. Our results show that the sleep-wake history can affect the clock molecular machinery directly at the level of chromatin binding thereby altering the cortical expression of Dbp and Per2 and likely other targets. Although the precise dynamics of the relationship between DNA-binding and mRNA expression, especially for Per2, remains elusive, the results also suggest that part of the reported circadian changes in DNA-binding of core clock components in tissues peripheral to the suprachiasmatic nuclei could, in fact, be sleep-wake driven.

Beautiful economic features of public landscaping in city beautiful

Full Text Available City beautiful was a movement of great reach and inspiration, which apparently, was initiated in Chicago in 1893 during the World’s Columbian Exposition. The movement’s premises were artistic, architectural, social, political and economic. Among the artistic and architectural aspects of the city beautiful movement, the provision of high quality public landscaping was of paramount importance. As for the economic rationale behind the movement, we encounter the thinking that a beautiful city should increase its residents’ enjoyment of the city’s attributes and hence attachment to the city, raise real estate values as well as expand city business, with larger sales of city goods and services to local and touristic customers. This paper examines the economic rationale behind the city beautiful movement. We consider a “regional” economy consisting of two adjacent cities, which are identical in many of its attributes, such as the sizes of their populations. We build a general equilibrium model for the agents (consumers and producers in this economy and demonstrate that the economic rationale behind the city beautiful movement is sound. Each city’s wealth and welfare are proportional to its quality level and a city’s quality level is proportional to the city’s public landscaping quality.

Gene therapies will only become a widespread tool in the clinical treatment of human diseases with the advent of gene transfer vectors that integrate genetic information stably, safely, effectively, and economically. Two decades after the discovery of the Sleeping Beauty (SB) transposon, it has been transformed into a vector system that is fulfilling these requirements. SB may well overcome some of the limitations associated with viral gene transfer vectors and transient non-viral gene delivery approaches that are being used in the majority of ongoing clinical trials. The SB system has achieved a high level of stable gene transfer and sustained transgene expression in multiple primary human somatic cell types, representing crucial steps that may permit its clinical use in the near future. This article reviews the most important aspects of SB as a tool for gene therapy, including aspects of its vectorization and genomic integration. As an illustration, the clinical development of the SB system toward gene therapy of age-related macular degeneration and cancer immunotherapy is highlighted.

Study Objectives: Increased cell injury would provide the type of change in constitution that would underlie sleep disruption as a risk factor for multiple diseases. The current study was undertaken to investigate cell injury and altered cell fate as consequences of sleep deprivation, which were predicted from systemic clues. Design: Partial (35% sleep reduction) and total sleep deprivation were produced in rats for 10 days, which was tolerated and without overtly deteriorated health. Recovery rats were similarly sleep deprived for 10 days, then allowed undisturbed sleep for 2 days. The plasma, liver, lung, intestine, heart, and spleen were analyzed and compared to control values for damage to DNA, proteins, and lipids; apoptotic cell signaling and death; cell proliferation; and concentrations of glutathione peroxidase and catalase. Measurements and Results: Oxidative DNA damage in totally sleep deprived rats was 139% of control values, with organ-specific effects in the liver (247%), lung (166%), and small intestine (145%). Overall and organ-specific DNA damage was also increased in partially sleep deprived rats. In the intestinal epithelium, total sleep deprivation resulted in 5.3-fold increases in dying cells and 1.5-fold increases in proliferating cells, compared with control. Two days of recovery sleep restored the balance between DNA damage and repair, and resulted in normal or below-normal metabolic burdens and oxidative damage. Conclusions: These findings provide physical evidence that sleep loss causes cell damage, and in a manner expected to predispose to replication errors and metabolic abnormalities; thereby providing linkage between sleep loss and disease risk observed in epidemiological findings. Properties of recovery sleep include biochemical and molecular events that restore balance and decrease cell injury. Citation: Everson CA, Henchen CJ, Szabo A, Hogg N.

Women's ability to broadly conceptualize beauty (i.e., perceive many looks, appearances, body sizes/shapes, and inner characteristics as beautiful) has been identified as a facet of positive body image in qualitative research. A scale is needed to be able to assess this construct within quantitative research. Therefore, we developed the Broad Conceptualization of Beauty Scale (BCBS), which measures the extent women define female beauty widely within external and internal characteristics, and examined its psychometric properties among four community samples totaling 1086 women. Exploratory and confirmatory factor analyses revealed a unidimensional structure with nine items. The internal consistency, test-retest reliability, and construct (convergent, discriminant, and incremental) validity of its scores were upheld. Researchers and clinicians can use the BCBS alone to assess women's perceptions of female beauty, or they can use the BCBS alongside women's perceptions of self-beauty to more comprehensively explore women's ability to broadly conceptualize beauty for others and themselves.

Beauty photoproduction in ep collisions has been studied with the ZEUS detector at HERA, at a center-of-mass energy of 300 GeV. Beauty quarks are tagged via their semi-leptonic decay into a muon or an electron. Events are selected by requiring the presence of two high-transverse energy jets and one high - p T lepton in the final state. The discrimination between beauty and background events is done by a fit to the p rel T variable, the transverse momentum of the lepton with respect to the jet axis. Total and differential cross sections are presented and compared to leading order Monte Carlo simulations and next-to-leading order QCD predictions. (author)

Sleep is critical for normal brain function and mental health. However, the molecular mechanisms mediating the impact of sleep loss on both cognition and the sleep electroencephalogram remain mostly unknown. Acute sleep loss impacts brain gene expression broadly. These data contributed to current hypotheses regarding the role for sleep in metabolism, synaptic plasticity and neuroprotection. These changes in gene expression likely underlie increased sleep intensity following sleep deprivation (SD). Here we tested the hypothesis that epigenetic mechanisms coordinate the gene expression response driven by SD. We found that SD altered the cortical genome-wide distribution of two major epigenetic marks: DNA methylation and hydroxymethylation. DNA methylation differences were enriched in gene pathways involved in neuritogenesis and synaptic plasticity, whereas large changes (>4000 sites) in hydroxymethylation where observed in genes linked to cytoskeleton, signaling and neurotransmission, which closely matches SD-dependent changes in the transcriptome. Moreover, this epigenetic remodeling applied to elements previously linked to sleep need (for example, Arc and Egr1) and synaptic partners of Neuroligin-1 (Nlgn1; for example, Dlg4, Nrxn1 and Nlgn3), which we recently identified as a regulator of sleep intensity following SD. We show here that Nlgn1 mutant mice display an enhanced slow-wave slope during non-rapid eye movement sleep following SD but this mutation does not affect SD-dependent changes in gene expression, suggesting that the Nlgn pathway acts downstream to mechanisms triggering gene expression changes in SD. These data reveal that acute SD reprograms the epigenetic landscape, providing a unique molecular route by which sleep can impact brain function and health.

This paper deals with the question of beauty and health in women. It discusses changing definitions of beauty as a result of influences from the entertainment, beauty and health product industries. Advertisements are seen to be major players in defining beauty through promotion of cosmetic, skin, hair and slimming products. Concerns relating to beauty become inculcated in girls through the process of socialisation as they mature into womanhood. The media plays a significant role in portraying the meaning of beauty through its representation of women. These influences largely influence and alter women's perceptions of their body image and in trying to meet the goals of beauty as represented by the media. This may result in dissatisfaction with their body image. Advertisements can encourage women to indulge in smoking as a fashionable trend or opt for plastic surgery in attempts to acquire beauty. This paper concludes with implications of the issues relating to changing perceptions of beauty and suggests recommendations.

Blood concentrations of cell-free DNA, which is considered to be released during apoptosis, are elevated under some pathological conditions such as cardiovascular disease and cancer. The association between obstructive sleep apnea (OSA) and cell-free DNA concentrations has not been reported so far. The purpose of the present study was to examine the association between OSA and plasma DNA concentrations. A case-control study was conducted using a total of 164 men aged 39-67 years, who were free of coronary heart disease and cancer. Laboratory-based overnight polysomnography was performed for all participants. On the basis of polysomnography, patients with an apnea-hypopnea index (AHI) = 5-30 events/h were defined as having mild-moderate OSA (n = 33) and those with >30 events/h were defined as having severe OSA (n = 49). All 82 controls had AHI DNA concentrations from all participants were analyzed for the beta-globin gene using fluorescence-based real-time polymerase chain reaction. Patients with severe OSA had significantly higher plasma DNA concentrations than persons with mild-moderate OSA and those without OSA (P DNA concentration (P DNA concentrations (>8 microg/L) had approximately fourfold higher odds of OSA than those with low DNA levels. Further data are warranted to confirm the association for men and to evaluate the association for women.

Serum cell-free DNA concentrations have been reported to increase in many acute diseases as well as in some chronic conditions such as cancer and autoimmune diseases. The aim of this study was to examine whether serum DNA concentrations were elevated in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). The effects of nasal continuous positive airway pressure (nCPAP) on serum DNA were also investigated. One hundred twenty-seven people diagnosed with OSAHS by polysomnography (PSG) were admitted into the OSAHS group, and 52 subjects without OSAHS were recruited for the control group. The OSAHS group was further divided into mild, moderate, and severe OSAHS subgroups based on their apnea-hypopnea index (AHI) during sleep. Ten patients with moderate and severe OSAHS were treated with nCPAP. Serum DNA, interleukin-6 (IL-6), and malonaldehyde (MDA) concentrations were measured and were found to be significantly higher in patients with moderate and severe OSAHS groups than those in the mild OSAHS and control groups (p DNA correlated positively with AHI, oxygen desaturation index (ODI), IL-6, and MDA, and negatively correlated with minimal oxygen saturation (miniSaO(2)) (all p DNA concentrations. After 6 months of nCPAP therapy, serum concentrations of DNA, IL-6, and MDA were significantly decreased (p DNA in patients with OSAHS was positively correlated with disease severity. Serum DNA may become an important parameter for monitoring the severity of OSAHS and effectiveness of therapy.

The medicalization of beauty

Paulo Poli Neto

2007-01-01

Full Text Available Concern with body image and medical interventions related to physical beauty has greatly increased in the past few years. The purpose of this study is to investigate how medicine is dealing with the theme of beauty. The 2003/2004 editions of the periodicals Aesthetic Surgery Journal and Aesthetic Plastic Surgery were analyzed, in order to investigate the rationality buttressing their discourse. Three categories were prioritized for this study: definition of aesthetic plastic surgery's study object; beauty patterns guiding interventions; and understanding popular demand for aesthetic corrections. Discourse is sustained by biomedical rationality, structured around a disease theory and a dual construction between normal and pathological, with emphasis on biology. In the articles, the beauty patterns guiding therapeutic practices are anchored in biological norms defined through several anthropometric measures, which refer to abstract concepts of beauty, harmony, proportionality and symmetry. In this discourse, there are no references to patterns or to social norms of beauty; motivation for aesthetic intervention appears to be rooted in low self-esteem related to the aging process or to some bodily nonconformity. As per the meaning of 'medicalization' adopted herein, biomedical rationality appropriates variations or anomalies of physical appearance, thus allowing the theme to be dealt with in terms of health and disease, normal and pathological.

Sleep deprivation has been associated with obesity among adults, and accumulating data suggests that stearoyl-CoA desaturase 1 (SCD1) expression has a relevant impact on fatty acid (FA) composition of lipid pools and obesity. The aim of this study was to investigate the effect of one-night total sleep deprivation (TSD) on DNA methylation in the 5'-prime region of SCD1, and whether detected changes in DNA methylation are associated with SCD activity indices (product to precursor FA ratios; 16:1n-7/16:0 and 18:1n-9/18:0) derived from serum phospholipids (PL). Sixteen young, normal-weight, healthy men completed two study sessions, one with one-night TSD and one with one-night normal sleep (NS). Sleep quality and length was assessed by polysomnography, and consisted of electroencephalography, electrooculography, and electromyography. Fasting whole blood samples were collected on the subsequent morning for analysis of DNA methylation and FAs in serum PL. Linear regression analyses were performed to assess the association between changes in DNA methylation and SCD activity indices. Three CpG sites close to the transcription start site (TSS) of SCD1 (cg00954566, cg24503796, cg14089512) were significantly differentially methylated in dependency of sleep duration (-log10 P-value > 1.3). Both SCD-16 and SCD-18 activity indices were significantly elevated (P DNA methylation changes of the three mentioned probes in the 5' region of SCD1. Our results suggest a relevant link between TSD, hepatic SCD1 expression and de-novo fatty acid synthesis via epigenetically driven regulatory mechanisms.

Brain-derived neurotrophic factor (Bdnf) regulates neuronal plasticity, slow wave activity and sleep homeostasis. Environmental stimuli control Bdnf expression through epigenetic mechanisms, but there are no data on epigenetic regulation of Bdnf by sleep or sleep deprivation. Here we investigated whether 5-methylcytosine (5mC) DNA modification at Bdnf promoters p1, p4 and p9 influences Bdnf1, Bdnf4 and Bdnf9a expression during the normal inactive phase or after sleep deprivation (SD) (3, 6 and 12 h, end-times being ZT3, ZT6 and ZT12) in rats in two brain areas involved in sleep regulation, the basal forebrain and cortex. We found a daytime variation in cortical Bdnf expression: Bdnf1 expression was highest at ZT6 and Bdnf4 lowest at ZT12. Such variation was not observed in the basal forebrain. Also Bdnf p1 and p9 methylation levels differed only in the cortex, while Bdnf p4 methylation did not vary in either area. Factorial analysis revealed that sleep deprivation significantly induced Bdnf1 and Bdnf4 with the similar pattern for Bdnf9a in both basal forebrain and cortex; 12 h of sleep deprivation decreased 5mC levels at the cortical Bdnf p4 and p9. Regression analysis between the 5mC promoter levels and the corresponding Bdnf transcript expression revealed significant negative correlations for the basal forebrain Bdnf1 and cortical Bdnf9a transcripts in only non-deprived rats, while these correlations were lost after sleep deprivation. Our results suggest that Bdnf transcription during the light phase of undisturbed sleep-wake cycle but not after SD is regulated at least partially by brain site-specific DNA methylation. © 2014 European Sleep Research Society.

We aimed to test a combined approach to identify conserved genes regulating sleep and to explore the association between DNA methylation and sleep length. We identified candidate genes associated with shorter versus longer sleep duration in college students based on DNA methylation using Illumina Infinium HumanMethylation450 BeadChip arrays. Orthologous genes in Caenorhabditis elegans were identified, and we examined whether their loss of function affected C. elegans sleep. For genes whose perturbation affected C. elegans sleep, we subsequently undertook a small pilot study to re-examine DNA methylation in an independent set of human participants with shorter versus longer sleep durations. Eighty-seven out of 485,577 CpG sites had significant differential methylation in young adults with shorter versus longer sleep duration, corresponding to 52 candidate genes. We identified 34 C. elegans orthologs, including NPY/flp-18 and flp-21, which are known to affect sleep. Loss of five additional genes alters developmentally timed C. elegans sleep (B4GALT6/bre-4, DOCK180/ced-5, GNB2L1/rack-1, PTPRN2/ida-1, ZFYVE28/lst-2). For one of these genes, ZFYVE28 (also known as hLst2), the pilot replication study again found decreased DNA methylation associated with shorter sleep duration at the same two CpG sites in the first intron of ZFYVE28. Using an approach that combines human epigenetics and C. elegans sleep studies, we identified five genes that play previously unidentified roles in C. elegans sleep. We suggest sleep duration in humans may be associated with differential DNA methylation at specific sites and that the conserved genes identified here likely play roles in C. elegans sleep and in other species. © Sleep Research Society 2017.

Sleep disorders associated with primary mitochondrial diseases.

Ramezani, Ryan J; Stacpoole, Peter W

2014-11-15

Primary mitochondrial diseases are caused by heritable or spontaneous mutations in nuclear DNA or mitochondrial DNA. Such pathological mutations are relatively common in humans and may lead to neurological and neuromuscular complication that could compromise normal sleep behavior. To gain insight into the potential impact of primary mitochondrial disease and sleep pathology, we reviewed the relevant English language literature in which abnormal sleep was reported in association with a mitochondrial disease. We examined publication reported in Web of Science and PubMed from February 1976 through January 2014, and identified 54 patients with a proven or suspected primary mitochondrial disorder who were evaluated for sleep disturbances. Both nuclear DNA and mitochondrial DNA mutations were associated with abnormal sleep patterns. Most subjects who underwent polysomnography had central sleep apnea, and only 5 patients had obstructive sleep apnea. Twenty-four patients showed decreased ventilatory drive in response to hypoxia and/ or hyperapnea that was not considered due to weakness of the intrinsic muscles of respiration. Sleep pathology may be an underreported complication of primary mitochondrial diseases. The probable underlying mechanism is cellular energy failure causing both central neurological and peripheral neuromuscular degenerative changes that commonly present as central sleep apnea and poor ventilatory response to hyperapnea. Increased recognition of the genetics and clinical manifestations of mitochondrial diseases by sleep researchers and clinicians is important in the evaluation and treatment of all patients with sleep disturbances. Prospective population-based studies are required to determine the true prevalence of mitochondrial energy failure in subjects with sleep disorders, and conversely, of individuals with primary mitochondrial diseases and sleep pathology. © 2014 American Academy of Sleep Medicine.

Beauty and cuteness in peripheral vision

Guo et al. (2011) showed that attractiveness was detectable in peripheral vision. Since there are different types of attractiveness (Rhodes, 2006), we investigated how beauty and cuteness are detected in peripheral vision with a brief presentation. Participants (n = 45) observed two Japanese female faces for 100 ms, then were asked to respond which face was more beautiful (or cuter). The results indicated that both beauty and cuteness were detectable in peripheral vision, but not in the same manner. Discrimination rates for judging beauty were invariant in peripheral and central vision, while discrimination rates for judging cuteness declined in peripheral vision as compared with central vision. This was not explained by lower resolution in peripheral vision. In addition, for male participants, it was more difficult to judge cuteness than beauty in peripheral vision, thus suggesting that gender differences can have a certain effect when judging cuteness. Therefore, central vision might be suitable for judging cuteness while judging beauty might not be affected by either central or peripheral vision. This might be related with the functional difference between beauty and cuteness. PMID:25999883

"Beauty lies in the eye of the beholder"? Aspects of beauty and attractiveness.

Discussing aesthetic issues and their management with patients is a growing area of dermatologic practice. Sometimes treatment options within one's own discipline are rapidly discussed, without a clear idea of the various aspects of the face which all combine to produce beauty and attractiveness. We review various features leading to the impression of beauty and attractiveness. Familiarity with these concepts should facilitate a broader discussion with the patient on the aspects of beauty and attractiveness beyond the borders of one's own discipline and also lead to multidisciplinary treatment options. We also examine the question how much the personality of the beholder himself is involved in the perception of attractiveness and beauty (of the person sitting opposite to him). The "ideal" face has an average profile with slightly protrusive and full lips. Attractiveness increases with average features and symmetry. Moreover, particular features such as the scheme of childlike characteristics combined with aspects of maturity and expression make a female face appear especially beautiful. Which attributes contribute to attractiveness of a man's face are controversial. Clear male signals such as a strong chin are likely not to increase attractiveness.

These lectures discuss methods for analyzing the decay of beauty hadrons (B mesons and beauty baryons) produced in pp interactions. At the c.m. energies around 14 TeV planned for the Large Hadron Collider (LHC) at CERN, the B meson production rate is expected to be ca 105 larger than in an e+e- B factory. The pp collider could then offer, in principle, important advantages. However, the detection of beauty hadrons produced in a pp collider will be a task of great complexity. In particular, the triggering difficulties of events in a large background will be one of the major problems. Therefore, it would be useful to discuss the various aspects that can be investigated in beauty physics arising from pp interactions. It is first described the general features of the formalisms of B mixing and search for CP violation in the meson decays. Then the specific problems appearing for beauty hadrons produced in pN interactions are considered. Some comparison between investigations which could be carried out with B factories and pp colliders are also mentioned, although this is not the main concern of these lectures. Finally it is also presented some elements of beauty baryon decays which can only be studied efficiently by means of pN interaction

Mutations in SMAD4 predispose to the development of gastrointestinal cancer, which is the third leading cause of cancer-related deaths. To identify genes driving gastric cancer (GC) development, we performed a Sleeping Beauty (SB) transposon mutagenesis screen in the stomach of Smad4(+/-) mutant mice. This screen identified 59 candidate GC trunk drivers and a much larger number of candidate GC progression genes. Strikingly, 22 SB-identified trunk drivers are known or candidate cancer genes, whereas four SB-identified trunk drivers, including PTEN, SMAD4, RNF43, and NF1, are known human GC trunk drivers. Similar to human GC, pathway analyses identified WNT, TGF-β, and PI3K-PTEN signaling, ubiquitin-mediated proteolysis, adherens junctions, and RNA degradation in addition to genes involved in chromatin modification and organization as highly deregulated pathways in GC. Comparative oncogenomic filtering of the complete list of SB-identified genes showed that they are highly enriched for genes mutated in human GC and identified many candidate human GC genes. Finally, by comparing our complete list of SB-identified genes against the list of mutated genes identified in five large-scale human GC sequencing studies, we identified LDL receptor-related protein 1B (LRP1B) as a previously unidentified human candidate GC tumor suppressor gene. In LRP1B, 129 mutations were found in 462 human GC samples sequenced, and LRP1B is one of the top 10 most deleted genes identified in a panel of 3,312 human cancers. SB mutagenesis has, thus, helped to catalog the cooperative molecular mechanisms driving SMAD4-induced GC growth and discover genes with potential clinical importance in human GC.

Diffractive beauty production at the LHC

Eggert, K.; Morsch, A.

1994-01-01

Using the framework of Pomeron exchange to describe diffractive pp collisions at the LHC we discuss beauty production in those events. The cross sections for beauty production at different diffractive masses and the topology for the beauty particles and the underlying event are given. When triggering on large diffractive masses, the beauty system is boosted into the Pomeron hemisphere opposite the underlying event, which tends to follow the excited proton direction. This may offer some advantages for the acceptance of beauty and its reconstruction in forward spectrometers. For the identification of diffractive events at the LHC collider, we present a scheme to measure the momentum loss of forward protons in the range 2x10 -3 < Δp/p <0.1. This momentum loss can be determined with a precision of about 10%. ((orig.))

Conditional gene expression in the mouse using a Sleeping Beauty gene-trap transposon

2006-06-01

Full Text Available Abstract Background Insertional mutagenesis techniques with transposable elements have been popular among geneticists studying model organisms from E. coli to Drosophila and, more recently, the mouse. One such element is the Sleeping Beauty (SB transposon that has been shown in several studies to be an effective insertional mutagen in the mouse germline. SB transposon vector studies have employed different functional elements and reporter molecules to disrupt and report the expression of endogenous mouse genes. We sought to generate a transposon system that would be capable of reporting the expression pattern of a mouse gene while allowing for conditional expression of a gene of interest in a tissue- or temporal-specific pattern. Results Here we report the systematic development and testing of a transposon-based gene-trap system incorporating the doxycycline-repressible Tet-Off (tTA system that is capable of activating the expression of genes under control of a Tet response element (TRE promoter. We demonstrate that the gene trap system is fully functional in vitro by introducing the "gene-trap tTA" vector into human cells by transposition and identifying clones that activate expression of a TRE-luciferase transgene in a doxycycline-dependent manner. In transgenic mice, we mobilize gene-trap tTA vectors, discover parameters that can affect germline mobilization rates, and identify candidate gene insertions to demonstrate the in vivo functionality of the vector system. We further demonstrate that the gene-trap can act as a reporter of endogenous gene expression and it can be coupled with bioluminescent imaging to identify genes with tissue-specific expression patterns. Conclusion Akin to the GAL4/UAS system used in the fly, we have made progress developing a tool for mutating and revealing the expression of mouse genes by generating the tTA transactivator in the presence of a secondary TRE-regulated reporter molecule.

Pediatric obstructive sleep apnea (OSA) leads to multiple end-organ morbidities that are mediated by the cumulative burden of oxidative stress and inflammation. Because not all children with OSA exhibit increased systemic inflammation, genetic and environmental factors may be affecting patterns of DNA methylation in genes subserving inflammatory functions. DNA from matched children with OSA with and without high levels of high-sensitivity C-reactive protein (hsCRP) were assessed for DNA methylation levels of 24 inflammatory-related genes. Primer-based polymerase chain reaction assays in a case-control setting involving 47 OSA cases and 31 control subjects were conducted to confirm the findings; hsCRP and myeloid-related protein (MRP) 8/14 levels were also assayed. Forkhead box P3 (FOXP3) and interferon regulatory factor 1 (IRF1) showed higher methylation in six children with OSA and high hsCRP levels compared with matched children with OSA and low hsCRP levels (P DNA methylation levels compared with children with OSA and low CRP levels and control subjects. IRF1 did not exhibit significant differences. FOXP3 DNA methylation levels correlated with hsCRP and MRP 8/14 levels and with apnea-hypopnea index (AHI), BMI z score, and apolipoprotein B levels. A stepwise multiple regression model showed that AHI was independently associated with FOXP3 DNA methylation levels (P gene, which regulates expression of T regulatory lymphocytes, is more likely to display increased methylation among children with OSA who exhibit increased systemic inflammatory responses. Thus, epigenetic modifications may constitute an important determinant of inflammatory phenotype in OSA, and FOXP3 DNA methylation levels may provide a potential biomarker for end-organ vulnerability.

Beauty at a glance: The feeling of beauty and the amplitude of pleasure are independent of stimulus duration.

Science.gov (United States)

Brielmann, Aenne A; Vale, Lauren; Pelli, Denis G

2017-12-01

Over time, how does beauty develop and decay? Common sense suggests that beauty is intensely felt only after prolonged experience of the object. Here, we present one of various stimuli for a variable duration (1-30 s), measure the observers' pleasure over time, and, finally, ask whether they felt beauty. On each trial, participants (N = 21) either see an image that they had chosen as "movingly beautiful," see an image with prerated valence, or suck a candy. During the stimulus and a further 60 s, participants rate pleasure continuously using a custom touchscreen web app, EmotionTracker.com. After each trial, participants judge whether they felt beauty. Across all stimulus kinds, durations, and beauty responses, the dynamic pleasure rating has a stereotypical time course that is well fit by a one-parameter model with a brief exponential onset (roughly 2.5 s), a sustained plateau during stimulus presentation, and a long exponential decay (roughly 70 s). Across conditions, only the plateau amplitude varies. Beauty and pleasure amplitude are nearly independent of stimulus duration. The final beauty rating is positively correlated with pleasure amplitude (r = 0.60), and nearly independent of duration (r = 0.10). Beauty's independence from duration is unlike Bentham's 18th-century notion of value (utility), which he supposed to depend on the product of pleasure amplitude and duration. Participants report having felt pleasure as strongly after a mere 1 s stimulus as after longer durations, up to 30 s. Thus, we find that amplitude of pleasure is independent of stimulus duration.

We studied the neural mechanisms that are engaged during the experience of beauty derived from sorrow and from joy, two experiences that share a common denominator (beauty) but are linked to opposite emotional valences. Twenty subjects viewed and rerated, in a functional magnetic resonance imaging scanner, 120 images which each had classified into the following four categories: beautiful and sad; beautiful and joyful; neutral; ugly. The medial orbito-frontal cortex (mOFC) was active during the experience of both types of beauty. Otherwise, the two experiences engaged different parts of the brain: joyful beauty engaged areas linked to positive emotions while sorrowful beauty engaged areas linked to negative experiences. Separate regions of the cerebellum were engaged during experience of the two conditions. A functional connectivity analysis indicated that the activity within the mOFC was modulated by the supplementary motor area/middle cingulate cortex, known to be engaged during empathetic experiences provoked by other peoples' sadness.

Gaine, Marie E; Chatterjee, Snehajyoti; Abel, Ted

2018-01-01

Sleep deprivation disrupts the lives of millions of people every day and has a profound impact on the molecular biology of the brain. These effects begin as changes within a neuron, at the DNA and RNA level, and result in alterations in neuronal plasticity and dysregulation of many cognitive functions including learning and memory. The epigenome plays a critical role in regulating gene expression in the context of memory storage. In this review article, we begin by describing the effects of epigenetic alterations on the regulation of gene expression, focusing on the most common epigenetic mechanisms: (i) DNA methylation; (ii) histone modifications; and (iii) non-coding RNAs. We then discuss evidence suggesting that sleep loss impacts the epigenome and that these epigenetic alterations might mediate the changes in cognition seen following disruption of sleep. The link between sleep and the epigenome is only beginning to be elucidated, but clear evidence exists that epigenetic alterations occur following sleep deprivation. In the future, these changes to the epigenome could be utilized as biomarkers of sleep loss or as therapeutic targets for sleep-related disorders.

The environmental injustice of beauty: framing chemical exposures from beauty products as a health disparities concern.

Zota, Ami R; Shamasunder, Bhavna

The obstetrics-gynecology community has issued a call to action to prevent toxic environmental chemical exposures and their threats to healthy human reproduction. Recent committee opinions recognize that vulnerable and underserved women may be impacted disproportionately by environmental chemical exposures and recommend that reproductive health professionals champion policies that secure environmental justice. Beauty product use is an understudied source of environmental chemical exposures. Beauty products can include reproductive and developmental toxicants such as phthalates and heavy metals; however, disclosure requirements are limited and inconsistent. Compared with white women, women of color have higher levels of beauty product-related environmental chemicals in their bodies, independent of socioeconomic status. Even small exposures to toxic chemicals during critical periods of development (such as pregnancy) can trigger adverse health consequences (such as impacts on fertility and pregnancy, neurodevelopment, and cancer). In this commentary, we seek to highlight the connections between environmental justice and beauty product-related chemical exposures. We describe racial/ethnic differences in beauty product use (such as skin lighteners, hair straighteners, and feminine hygiene products) and the potential chemical exposures and health risks that are associated with these products. We also discuss how targeted advertising can take advantage of mainstream beauty norms to influence the use of these products. Reproductive health professionals can use this information to advance environmental justice by being prepared to counsel patients who have questions about toxic environmental exposures from beauty care products and other sources. Researchers and healthcare providers can also promote health-protective policies such as improved ingredient testing and disclosure for the beauty product industry. Future clinical and public health research should consider beauty

Age-related disease risk has been linked to short sleep duration and sleep disturbances; however, the specific molecular pathways linking sleep loss with diseases of aging are poorly defined. Key cellular events seen with aging, which are thought to contribute to disease, may be particularly sensitive to sleep loss. We tested whether one night of partial sleep deprivation (PSD) would increase leukocyte gene expression indicative of DNA damage responses (DDR), the senescence-associated secretory phenotype (SASP), and senescence indicator p16(INK4a) in older adult humans, who are at increased risk for cellular senescence. Community-dwelling older adults aged 61-86years (n=29; 48% male) underwent an experimental partial sleep deprivation (PSD) protocol over 4 nights, including adaptation, an uninterrupted night of sleep, partial sleep deprivation (sleep restricted 3-7AM), and a subsequent full night of sleep. Blood samples were obtained each morning to assess peripheral blood mononuclear cell (PBMC) gene expression using Illumina HT-12 arrays. Analyses of microarray results revealed that SASP (psleep deprivation activates PBMC gene expression patterns consistent with biological aging in this older adult sample. PSD enhanced the SASP and increased the accumulation of damage that initiates cell cycle arrest and promotes cellular senescence. These findings causally link sleep deprivation to the molecular processes associated with biological aging. Copyright © 2015 Elsevier Inc. All rights reserved.

DNA profiling of trace DNA recovered from bedding.

Petricevic, Susan F; Bright, Jo-Anne; Cockerton, Sarah L

2006-05-25

Trace DNA is often detected on handled items and worn clothing examined in forensic laboratories. In this study, the potential transfer of trace DNA to bedding by normal contact, when an individual sleeps in a bed, is examined. Volunteers slept one night on a new, lower bed sheet in their own bed and one night in a bed foreign to them. Samples from the sheets were collected and analysed by DNA profiling. The results indicate that the DNA profile of an individual can be obtained from bedding after one night of sleeping in a bed. The DNA profile of the owner of the bed could also be detected in the foreign bed experiments. Since mixed DNA profiles can be obtained from trace DNA on bedding, caution should be exercised when drawing conclusions from DNA profiling results obtained from such samples. This transfer may have important repercussions in sexual assault investigations.

Obstructive sleep apnea (OSA) is characterized by phenotypic variations, which can be partly attributed to specific gene polymorphisms. Recent studies have focused on the role of epigenetic mechanisms in order to permit a more precise perception about clinical phenotyping and targeted therapies. The aim of this review was to synthesize the current state of knowledge on the relation between DNA methylation patterns and the development of pediatric OSA, in light of the apparent limited literature in the field. We performed an electronic search in PubMed, EMBASE, and Google Scholar databases, including all types of articles written in English until January 2017. Literature was apparently scarce; only 2 studies on pediatric populations and 3 animal studies were identified. Forkhead Box P3 (FOXP3) DNA methylation levels were associated with inflammatory biomarkers and serum lipids. Hypermethylation of the core promoter region of endothelial Nitric Oxide Synthase (eNOS) gene in OSA children were related with decreased eNOS expression. Additionally, increased expression of genes encoding pro-oxidant enzymes and decreased expression of genes encoding anti-oxidant enzymes suggested that disturbances in oxygen homeostasis throughout neonatal period predetermined increased hypoxic sensing in adulthood. In conclusion, epigenetic modifications may be crucial in pediatric sleep disorders to enable in-depth understanding of genotype-phenotype interactions and lead to risk assessment. Epigenome-wide association studies are urgently needed to validate certain epigenetic alterations as reliable, novel biomarkers for the molecular prognosis and diagnosis of OSA patients with high risk of end-organ morbidity.

Toward a brain-based theory of beauty.

Science.gov (United States)

Ishizu, Tomohiro; Zeki, Semir

2011-01-01

We wanted to learn whether activity in the same area(s) of the brain correlate with the experience of beauty derived from different sources. 21 subjects took part in a brain-scanning experiment using functional magnetic resonance imaging. Prior to the experiment, they viewed pictures of paintings and listened to musical excerpts, both of which they rated on a scale of 1-9, with 9 being the most beautiful. This allowed us to select three sets of stimuli--beautiful, indifferent and ugly--which subjects viewed and heard in the scanner, and rated at the end of each presentation. The results of a conjunction analysis of brain activity showed that, of the several areas that were active with each type of stimulus, only one cortical area, located in the medial orbito-frontal cortex (mOFC), was active during the experience of musical and visual beauty, with the activity produced by the experience of beauty derived from either source overlapping almost completely within it. The strength of activation in this part of the mOFC was proportional to the strength of the declared intensity of the experience of beauty. We conclude that, as far as activity in the brain is concerned, there is a faculty of beauty that is not dependent on the modality through which it is conveyed but which can be activated by at least two sources--musical and visual--and probably by other sources as well. This has led us to formulate a brain-based theory of beauty.

The Connection between Beauty and Morality in Kant's aesthetics

Directory of Open Access Journals (Sweden)

Ali salmani

2015-09-01

Full Text Available Abstract At first glance it seems that Kant distinguishes beauty from morality because while analyzing the matter of beauty according to quality, he explicitly separates pleasure of beauty from pleasure of agreeable and pleasure of good; and believes that the pleasure of the beauty is neither to satisfy our physical desires nor to achieve a moral purpose. On the other hand, Kant speaks of a connection between beauty and morality in some sections of his critique of judgment. This essay intends to study the mentioned sections and clarifies how one can distinguish beauty from morality and simultaneously believes in the connection between beauty and morality. Following this, we are going to discuss why Kant deems such a connection necessary. Examining this matter, we will find out that morality and aesthetics can be indirectly related to each other. Kant's most major concern with regard to the connection between beauty and morality is the connection between feelings and foredoom.

Post-human body and beauty.

Science.gov (United States)

Russo, Maria Teresa; Di Stefano, Nicola

2014-01-01

The article calls into question the very possibility of a post-human aesthetics, starting from the following premise: rather than post-human, it is more correct to speak of post-natural, indicating by this expression a reality produced through a new type of evolution, which does not simply change human nature, but de-natures it, radically transforming it into an artefact. This post-nature which aspires to be perfect, immortal, invulnerable, is entirely devoid of beauty. In fact, while there may be an aesthetic of the artificial and of the artefact if it is in relation to objects, there is, however, no aesthetic of the post-human body. This is because is configured as a non-body and does not have the characteristics for what is commonly intended as beauty (harmony between matter and form, a reflection of inner life, uniqueness). Also in this case, it is more correct to speak of post-beauty, which in its properties appears to be the mirror image of beauty and ultimately, represents its complete dissolution.

Full Text Available This philosophical paper explores the aesthetic argument for landscape conservation. The main claim is that the experience of beautiful landscapes is an essential part of the good human life. Beautiful landscapes make us feel at home in the world. Their great and irreplaceable value lies therein. To establish this claim, the concepts of landscape and “Stimmung” are clarified. It is shown how “Stimmung” (in the sense of mood is infused into landscape (as atmosphere and how we respond to it aesthetically. We respond by resonating or feeling at home. The paper ends by indicating how art can help us to better appreciate landscape beauty. This is done by way of an example from contemporary nature poetry, Michael Donhauser’s Variationen in Prosa, which begins with “Und was da war, es nahm uns an” (“And what was there accepted us”.

Collider phenomenology of light strange-beauty squarks

International Nuclear Information System (INIS)

Cheung, Kingman; Hou Weizshu

2004-01-01

Strong mixing between right-handed strange and beauty squarks is a possible solution to the CP violation discrepancy in B→φK S decay as recently suggested by the Belle data. In this scenario, thanks to the strong mixing one of the strange-beauty squarks can be as light as 200 GeV, even though the generic supersymmetry scale is at TeV. In this work, we study the production of this light right-handed strange-beauty squark at hadronic colliders and discuss the detection in various decay scenarios. Detection prospect at the Tevatron run II is good for the strange-beauty squark mass up to about 300 GeV

Beauty production at HERA using the ZEUS experiment

International Nuclear Information System (INIS)

Yaguees, A

2008-01-01

Beauty quark production in ep collisions is being studied with the ZEUS detector at HERA. The latest measurements of beauty production in deep inelastic scattering and photoproduction regime are presented. The first measurement exploits the potential of the ZEUS microvertex detector to identify beauty in photoproduction dijet events with a muon in the final state. The second is based on statistical methods to determine the fraction of beauty in photoproduction dijet events with an electron in the final state. Finally, the first measurement by ZEUS of the beauty contribution to the proton structure function, F 2 bb, in deep inelastic scattering is presented. The three measurements are compared with QCD predictions as well as with previous results. All the results presented here are preliminary

Beauty in abstract paintings: Perceptual contrast and statistical properties

2014-03-01

Full Text Available In this study, we combined the behavioral and objective approach in the field of empirical aesthetics. First, we studied the perception of beauty by investigating shifts in evaluation on perceived beauty of abstract artworks (Experiment 1. Because the participants showed heterogeneous individual preferences for the paintings, we divided them into seven clusters for the test. The experiment revealed a clear pattern of perceptual contrast. The perceived beauty of abstract paintings increased after exposure to paintings that were rated as less beautiful, and it decreased after exposure to paintings that were rated as more beautiful. Next, we searched for correlations of beauty ratings and perceptual contrast with statistical properties of abstract artworks (Experiment 2. The participants showed significant preferences for certain image properties. These preferences differed between the clusters of participants. Strikingly, next to color measures like hue, saturation, value and lightness, the recently described PHOG self-similarity value seems to be a predictor for aesthetic appreciation of abstract artworks. We speculate that the shift in evaluation in Experiment 1 was, at least in part, based on low-level adaptation to some of the statistical image properties analyzed in Experiment 2. In conclusion, our findings demonstrate that the perception of beauty in abstract artworks is altered after exposure to beautiful or non-beautiful images and correlates with particular image properties, especially color measures and self-similarity.

A beautiful question finding nature’s deep design

CERN Document Server

Wilczek, Frank

2015-01-01

Artists as well as scientists throughout human history have pondered this “beautiful question.” With Nobel laureate Frank Wilczek as your guide, embark on a voyage of related discoveries, from Plato and Pythagoras up to the present. Wilczek’s groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature. In fact, every major advance in his career came from this intuition: to assume that the universe embodies beautiful forms, forms whose hallmarks are symmetry—harmony, balance, proportion—and economy. There are other meanings of “beauty,” but this is the deep logic of the universe—and it is no accident that it is also at the heart of what we find aesthetically pleasing and inspiring. Wilczek is hardly alone among great scientists in charting his course using beauty as his compass. As he reveals in A Beautiful Question, this has been the heart of scientific pursuit from Pythagoras, the ancient Greek who was the first to argue that “all thi...

The aim of the present study was to analyze the differences between the genes of the mitochondrial DNA (mtDNA) displacement loop (D-loop) region and the Cambridge Reference sequence, in order to screen the mutation sites and investigate the correlation between mutations, clinical parameters and complications associated with obstructive sleep apnea-hypopnea syndrome (OSAHS). mtDNA was obtained from male patients with OSAHS in the Zhejiang Province. In total, 60 male patients with OSAHS and 102 healthy adults were assessed to determine the levels of fasting blood glucose, total cholesterol, triglyceride (TG) and high-density and low-density lipoproteins (LDL). Furthermore, peripheral mtDNA was extracted and bidirectional sequencing was conducted to enable mutation screening. In the mtDNA D-loop region, 178 mutation sites were identified, of which 115 sites were present in the two groups. The number of non-common sites in the OSAHS group was significantly higher compared with the control group (P0.05). A total of 21 cases in the severe OSAHS group exhibited mutation rates of >10%. In the control group, there were 24 cases where the np73A-G and np263A-G mutations were predominant. The np303-np315 region was identified to be the highly variable region and various mutation forms were observed. Statistically significant differences were observed in the neck perimeter, TG and LDL levels among the OSAHS-no-mutation subgroups (P<0.05) and LDL was shown to be associated with an mtDNA mutation in the OSAHS group. Numerous polymorphic mutation sites were identified in the mtDNA D-loop region of the OSAHS group. Therefore, mtDNA mutation sites may be closely associated with the clinical manifestations and complications of OSAHS.

2016-06-01

Three different, but related topics are the subject of this thesis, performed in the context of the ZEUS and CMS groups at DESY. The first measurement of the MS beauty-quark mass m b (m b ) at an electron-proton collider is presented. The measurement is based on a QCD analysis of beauty production cross sections in deep inelastic (DIS) ep scattering measured by ZEUS at HERA, together with inclusive DIS HERA data, using Next-to-Leading-Order QCD predictions. The measured value of the running beauty-quark mass in the MS scheme was found to be m b (m b )=4.07±0.14 (fit) +0.01 -0.07 (mod.) +0.05 -0.00 (param.) +0.08 -0.05 ( theo.) GeV, which is in good agreement with the world average Particle Data Group value and previous measurements at electron-positron colliders. It is also found to be consistent with the expected running of m b (μ). A first measurement of the charm-quark mass m c (μ) running in the MS scheme is presented. The measurement is based on a QCD analysis of the published H1 and ZEUS combination of charm cross section measurements in DIS ep scattering at HERA, together with inclusive DIS HERA data, using Next-to-Leading-Order QCD predictions. The running charm-quark mass m c (μ) was measured at different scales μ and is presented in a charm-quark mass running plot with a comparison to the world average Particle Data Group m c (m c ) evolved to higher scales. The running is found to be consistent with the expectations from QCD. The uncertainties of the theoretical predictions for Higgs production in association with beauty-quarks originating from the beauty-quark mass were studied and reduced for massive and massless QCD calculations. The beauty-quark mass measurement m b (m b ) was used to decrease the variation of the beauty-quark mass to 0.17 GeV. It was shown that the uncertainty from the beauty-quark mass m b (m b ) in the case of massive calculations for Hb anti b production at LHC can be reduced to 2%. This makes it negligible compared to other

Two beautiful new particles

CERN Multimedia

2012-01-01

In beautiful agreement with the Standard Model, two new excited states (see below) of the Λb beauty particle have just been observed by the LHCb Collaboration. Similarly to protons and neutrons, Λb is composed of three quarks. In the Λb’s case, these are up, down and… beauty.   Although discovering new particles is increasingly looking like a routine exercise for the LHC experiments (see previous features), it is far from being an obvious performance, particularly when the mass of the particles is high. Created in the high-energy proton-proton collisions produced by the LHC, these new excited states of the Λb particle have been found to have a mass of, respectively, 5912 MeV/c2 and 5920 MeV/c2. In other words, they are over five times heavier than the proton or the neutron. Physicists only declare a discovery when data significantly show the relevant signal. In order to do that, they often have to analyse large samples of data. To ...

Kang, Il Gyu; Jung, Joo Hyun; Kim, Seon Tae

2013-06-01

Obstructive sleep apnea syndrome (OSAS) is associated with repeated hypoxia and re-oxygenation. This characteristic of OSAS may cause oxidative stress and DNA damage. However, the link of OSAS with oxidative stress and DNA damage is still controversial. In the current study, we investigated whether OSAS causes DNA damage using alkaline single-cell gel electrophoresis (comet assay) and measuring oxidative stress by monitoring serum malondialdehyde (MDA) levels. From March 2009 to August 2010, 51 patients who underwent polysomnography (PSG) during the night were enrolled in this study. We obtained serum from the patients at 6 AM. DNA damage and oxidative stress were evaluated using a comet assay and measuring serum MDA, respectively. We divided the patients into two groups according to the existence of comets appearing in the comet assay. Group 1 included 44 patients with negative assay results and group 2 consisted of seven patients with positive comet assay findings. We compared the age, gender proportion, PSG data (respiratory disturbance index [RDI], lowest O2 saturation level, and arousal index [AI]), time of disease onset, smoking habits, and serum MDA levels between the two groups. The average age and gender proportion of the two groups were not statistically different (P>0.05). The average of RDI for group 1 was 30.4±18.4 and 8.0±7.7 (P0.05). No relationship between positive comet assay results and OSAS severity was identified. Results of the current study showed that OSAS was not associated with DNA damage as measured by comet assays or oxidative stress according to serum MDA levels.

Natural Tendency towards Beauty in Humans: Evidence from Binocular Rivalry.

Science.gov (United States)

Mo, Ce; Xia, Tiansheng; Qin, Kaixin; Mo, Lei

2016-01-01

Although human preference for beauty is common and compelling in daily life, it remains unknown whether such preference is essentially subserved by social cognitive demands or natural tendency towards beauty encoded in the human mind intrinsically. Here we demonstrate experimentally that humans automatically exhibit preference for visual and moral beauty without explicit cognitive efforts. Using a binocular rivalry paradigm, we identified enhanced gender-independent perceptual dominance for physically attractive persons, and the results suggested universal preference for visual beauty based on perceivable forms. Moreover, we also identified perceptual dominance enhancement for characters associated with virtuous descriptions after controlling for facial attractiveness and vigilance-related attention effects, which suggested a similar implicit preference for moral beauty conveyed in prosocial behaviours. Our findings show that behavioural preference for beauty is driven by an inherent natural tendency towards beauty in humans rather than explicit social cognitive processes.

This article is a commentary on 'Ten years of a model of aesthetic appreciation and aesthetic judgments: The aesthetic episode - developments and challenges in empirical aesthetics' (Leder & Nadal, 2014, this issue). It focuses on the importance of beauty in aesthetic appreciation and aesthetic judgments. Beauty is considered as a formal inherent property of visual stimuli that has the potential to elicit visual pleasure by direct sensory stimulation. It is argued that any comprehensive model of aesthetic experience must account fully for cognitive aspects of aesthetics (cultural, conceptual, psychological, and individual factors) as well as intrinsic properties of beautiful visual stimuli and how they relate to basic mechanisms of visual perception, which are universal among humans. © 2014 The British Psychological Society.

Literary aesthetics: beauty, the brain, and Mrs. Dalloway.

Science.gov (United States)

Hogan, Patrick Colm

2013-01-01

Empirical research indicates that beauty is in part a matter of prototype approximation. Some research suggests that unanticipated pattern recognition is important as well. This essay begins by briefly outlining an account of beauty based on these factors. It goes on to consider complications. Minor complications include the partial incompatibility of these accounts and the importance of differentiating judgments of beauty from aesthetic response. More serious issues include the relative neglect of literature in neurologically-based discussions of beauty, which tend to focus on music or visual art. There is also a relative neglect of emotion, beyond the reward system. Finally, there is the almost complete absence of the sublime. After considering these problems broadly, the essay turns to Virginia Woolf's Mrs. Dalloway, examining its treatment of beauty and sublimity. The aim of this section is not merely to illuminate Woolf's novel by reference to neuroscientific research. It is equally, perhaps more fully, to expand our neuroscientifically grounded account of aesthetic response by drawing on Woolf's novel. In Mrs. Dalloway, there are gestures toward prototypes and patterns in beauty. But the key features are clearly emotional. Specifically, the emotions at issue in feelings of beauty and sublimity appear to be primarily attachment, on the one hand, and a profound sense of isolation, on the other. Woolf's novel also points us toward other features of aesthetic experience, crucially including the emotion-sharing that is a key function of the production and circulation of art. © 2013 Elsevier B.V.

Brain correlates of aesthetic judgment of beauty.

Jacobsen, Thomas; Schubotz, Ricarda I; Höfel, Lea; Cramon, D Yves V

2006-01-01

Functional MRI was used to investigate the neural correlates of aesthetic judgments of beauty of geometrical shapes. Participants performed evaluative aesthetic judgments (beautiful or not?) and descriptive symmetry judgments (symmetric or not?) on the same stimulus material. Symmetry was employed because aesthetic judgments are known to be often guided by criteria of symmetry. Novel, abstract graphic patterns were presented to minimize influences of attitudes or memory-related processes and to test effects of stimulus symmetry and complexity. Behavioral results confirmed the influence of stimulus symmetry and complexity on aesthetic judgments. Direct contrasts showed specific activations for aesthetic judgments in the frontomedian cortex (BA 9/10), bilateral prefrontal BA 45/47, and posterior cingulate, left temporal pole, and the temporoparietal junction. In contrast, symmetry judgments elicited specific activations in parietal and premotor areas subserving spatial processing. Interestingly, beautiful judgments enhanced BOLD signals not only in the frontomedian cortex, but also in the left intraparietal sulcus of the symmetry network. Moreover, stimulus complexity caused differential effects for each of the two judgment types. Findings indicate aesthetic judgments of beauty to rely on a network partially overlapping with that underlying evaluative judgments on social and moral cues and substantiate the significance of symmetry and complexity for our judgment of beauty.

Beauty photoproduction using decays into muons at HERA

Energy Technology Data Exchange (ETDEWEB)

Samson, U.

2008-05-15

Inclusive cross-sections for the production of open beauty in ep collisions at HERA are measured. The data were recorded with the ZEUS detector between 1996 and 2000. The measurements are restricted to photoproduction processes, i.e. collision events with small four-momentum transfer squared, Q{sup 2}{approx}0. Two jets with transverse momentum p{sub T}>7(6) GeV and pseudo-rapidities vertical stroke {eta} vertical stroke <2.5 are required. The flavour is tagged by the identification of muons from semi-leptonic decays of the beauty quark. The variable used to discriminate between beauty and background is the transverse momentum of the muon with respect to the jet axis. The fraction of beauty is determined by a fit of Monte Carlo templates to the data. Cross-sections have been measured as a function of the muon and jet variables as well as a function of dijet correlation variables. Dijet correlations in beauty production have been measured for the first time in ZEUS and are found in agreement with QCD NLO predictions. (orig.)

Song is a kind of combination of language and music. Song achieves its aesthetic information and arouses feeling with its own sentiments and aesthetic effect. However, various kinds of present problems lead to much loss of beauty. Besides, the theoretical works concerning this area is much meager. Translation of English songs into Chinese has been studied from functional equivalence theory or the functionalism. The present thesis offers a new perspective―beauty in sound from Xu Yuanchong's"three beauties principle", aiming to seek possible ways to represent beauty in translation practice, and some typical examples are compared and analyzed.

The experience of mathematical beauty and its neural correlates

2014-01-01

Many have written of the experience of mathematical beauty as being comparable to that derived from the greatest art. This makes it interesting to learn whether the experience of beauty derived from such a highly intellectual and abstract source as mathematics correlates with activity in the same part of the emotional brain as that derived from more sensory, perceptually based, sources. To determine this, we used functional magnetic resonance imaging (fMRI) to image the activity in the brains of 15 mathematicians when they viewed mathematical formulae which they had individually rated as beautiful, indifferent or ugly. Results showed that the experience of mathematical beauty correlates parametrically with activity in the same part of the emotional brain, namely field A1 of the medial orbito-frontal cortex (mOFC), as the experience of beauty derived from other sources.

Theoretical Framework and Model Design for Beautiful Countryside Construction in China

Directory of Open Access Journals (Sweden)

ZHENG Xiang-qun

2015-04-01

Full Text Available In the context of China today, the process of beautiful countryside construction mainly imitates the patterns of‘urbanization’construction. However, this approach leads to the loss of countryside characteristics and the separation of agricultural culture. Therefore, it's urgent to carry out research of the theoretical framework and model design for beautiful countryside construction. In this paper, based on the analysis of the beautiful countryside construction connotation, the basic theory of beautiful countryside construction was summarized in three aspects: rural complex ecosystem model, multi-functionality of rural model and sustainable development evaluation model. The basic idea of the beautiful countryside construction mode was studied. The design method of beautiful countryside construction mode was proposed in three levels: planning, scheming and evaluating. The research results might offer scientific reference for improving the scientific and operational nature of beautiful countryside construction.

ISLAMIC BEAUTY: Socio-Semiotic Analysis of Facial Foam and Body Lotion Advertisement

Full Text Available This paper attempts to answer how Islamic Women define the concept of beauty in Ponds advertisement white beauty facial foam and body lotion on television. This study uses a socio-semiotic approach described through three aspects of social context, namely field, tenor, and mode. It argues that Ponds’ definition of a beauty only refers to physical standards, that is, women who have white skin and use both Ponds White Beauty Facial Foam and Foam Body Lotion. Further, television through Ponds advertising is considered as a commercial institution that supports the main idea of capitalism. However, Islamic women consider beautiful physically and spiritually. It suggests that the beautiful women are those who obey and surrender to Allah SWT. In short, Islamic women do not agree with the meaning of beauty resulted from Ponds White Beauty Facial Foam and Ponds Body Lotion advertisement. Rather, beauty consists of both body and, more importantly, soul.

Hadroproduction characteristics of charm and beauty

International Nuclear Information System (INIS)

Reucroft, S.

1987-01-01

In this article the authors review the present status of their knowledge on the hadroproduction characteristics of charm and beauty. During a brief description of the properties of all charm and beauty particles reportedly observed in hadron-hadron experiments they discuss the strengths and weaknesses of the various experimental techniques. In particular they emphasise the quantitative problems associated with nuclear target experiments and show the progress that is being made in understanding the A-dependence problem. Focussing on charm cross sections the authors see that the data are becoming sufficiently good to give us a reliable and coherent picture which provides a serious test of the QCD fusion model. This same fusion model is then used with existing beauty cross section determinations to make some extrapolations. Finally, a few remaining puzzles and curiosities are underlined

This study explores whether sleep duration is associated with sperm chromatin integrity. To do so, we conducted a three-phase panel study of 796 male volunteers from colleges in Chongqing (China) from 2013 to 2015. Sleep duration was measured using a modified Munich Chronotype Questionnaire. Sperm DNA integrity was examined via Sperm Chromatin Structure Assay and Comet assay. Setting 7-7.5 h day -1 of sleep duration as a reference, either longer or shorter sleep duration was associated negatively with high DNA stainability (HDS) (P = 0.009), which reflected the immaturity of sperm chromatin. The volunteers with > 9.0 h day -1 sleep and those with ≤ 6.5 h day -1 sleep had 40.7 and 30.3% lower HDS than did volunteers with 7-7.5 h day -1 sleep. No association was found between sleep duration and DNA fragmentation index or Comet assay parameters. This study suggests that sleep duration is associated with sperm chromatin integrity. Further studies are required to validate these findings and investigate the mechanism underlying this association. © 2017 European Sleep Research Society.

Nucleosomes and cell-free double-stranded DNA (dsDNA) have been suggested as promising biomarkers in cell death-related diseases, such as acute coronary syndrome (ACS). Currently, the impact of obstructive sleep apnea (OSA) in patients with ACS is unclear. Our aim was to evaluate the relationship between OSA, dsDNA, and nucleosomes and to assess their potential implication in the development of ACS. Up to 549 patients were included in the study and divided into four groups (145 ACS; 290 ACS + OSA; 62 OSA; 52 controls). All patients underwent a sleep study, and serum concentrations of dsDNA and nucleosomes were measured. Nucleosome and dsDNA levels were higher in patients with OSA than in controls (nucleosomes: 1.47 ± 0.88 arbitary units [AU] vs. 1.00 ± 0.33 AU; p Sleep Research Society 2017.

THE BEAUTY OF THE WORLD IN PLATO’S TIMAEUS

Directory of Open Access Journals (Sweden)

O’Meara, Dominic

2014-01-01

Full Text Available In the Timaeus Plato describes the world as the ‘most beautiful’ (kallistos, 29a5 of generated things. Perhaps indeed this is the first systematic description of the beauty of the world. It is, at any rate, one of the most influential statements of the theme. The Stoics were deeply convinced by it and later, in the third century A.D., at a time when contempt and hate for the world were propagated by Gnostic movements, Plotinus, interpreting the Timaeus, would write magnificent passages on the beauty and value of the world. But what does Plato mean by the ‘beauty’ of the world? What makes the world beautiful? In this paper these questions are approached first (1 by a brief discussion of the distinction which Plato appears to make in the Timaeus between beauty and the good. In one passage (Tim. 87c ‘measure’ seems to relate to this distinction. It is suitable then (2 to look at a section of another late work of Plato, the Philebus, where the themes of beauty, goodness and measure may be compared in more detail. The theme of measure then takes us back (3 to the Timaeus, in order to examine the role played by measure, in particular mathematical measure, in constituting the beauty of the world. I discuss in detail the way in which mathematical structures make for the beauty of soul and body in the living whole that is the world.

Sublimity and beauty: A view from nursing aesthetics.

2016-03-01

Several authors have focused on the aesthetics of nursing care from diverse perspectives; however, there are few studies about the sublime and the beautiful in nursing. To identify beautiful and sublime moments in the context of the aesthetics of nursing care. A theoretical reflection has been contemplated about sublime and beautiful values in the context of the aesthetics of nursing care from the cultural history perspective. For that purpose, a revision of this issue has been completed. The terms 'beautiful' and 'sublime' have been analysed to identify the characteristics of both in the context of nursing care. We have followed all ethical requirements regarding the sources, conducting research and authorship. There is no conflict of interest in this paper. With aesthetic knowledge, the nurse expresses the artistic nature of nursing care by appreciating the act of caring for individuals. The sublime is a complex phenomenon, since apparently contrary feelings are interwoven. Nursing care is an art with an anthropological object-subject on which the 'artist' applies their prior knowledge and skills. Feelings and emotions that develop during the clinical nursing practice - especially at times sublime and beautiful, aesthetic - constitute experiences which are professionally significant. © The Author(s) 2015.

Ram, S.N.; Singh, C.P.

1982-08-01

Strong interaction coupling parameters of particles with beauty quantum number are obtained using dispersion sum rules in various forms, e.g. current algebra sum rules, superconvergence sum rules and finite energy sum rules etc. These sum rules lead to a set of algebraic relations among masses and coupling constants. We compare the hadronic couplings of beautiful particles as obtained from various techniques and discuss their implications on the hadronic production of these states. (author)

Contribution of sleep to the repair of neuronal DNA double-strand breaks: evidence from flies and mice

OpenAIRE

Bellesi, Michele; Bushey, Daniel; Chini, Mattia; Tononi, Giulio; Cirelli, Chiara

2016-01-01

Exploration of a novel environment leads to neuronal DNA double-strand breaks (DSBs). These DSBs are generated by type 2 topoisomerase to relieve topological constrains that limit transcription of plasticity-related immediate early genes. If not promptly repaired, however, DSBs may lead to cell death. Since the induction of plasticity-related genes is higher in wake than in sleep, we asked whether it is specifically wake associated with synaptic plasticity that leads to DSBs, and whether slee...

Kong, Fanchang; Zhang, Yan; Tian, Yuan; Fan, Cuiying; Zhou, Zongkui

2015-03-01

This study examines the electrophysiological correlates of beauty evaluation when participants performed the self-reference task. About 13 (7 men, 6 women) undergraduates participated in the experiment using event-related potentials. Results showed that the response to self-relevant information was faster compared to other-relevant information and no significant differences for self-relevant relative to mother-relevant information were observed. Both physical and interior beauty words for self-relevant information showed an enhanced late positive component as compared to other-relevant information. Physical beauty for self-relevant information yielded a larger late positive component in contrast to mother-relevant information but not for interior beauty. This study indicates that beauty is specific to the person who judges it though an individual and one's mother may hold similar views of interior beauty.

Fixed target beauty physics from Tevatron to SSC (E771)

Lau, K.

1992-01-01

The E771 beauty experiment at Fermilab is described. The Super Fixed Target Beauty Facility (SFT) proposal to perform fixed target beauty physics at the SSC is a natural evolution. The unique features of SFT include crystal channeling extraction from the SSC main ring, which allows the experiment to operate concurrently with the collider experiments. The slow extraction rate (≅2x10 8 protons/s) does not limit the lifetime of the stored beams. The proposed beauty spectrometer and its capability in CP violation studies are described.

Measurement of beauty and charm production in deep inelastic scattering at HERA and measurement of the beauty-quark mass

International Nuclear Information System (INIS)

Abramowicz, H.; Abt, I.; Adamczyk, L.

2014-05-01

The production of beauty and charm quarks in ep interactions has been studied with the ZEUS detector at HERA for exchanged four-momentum squared 5 2 2 using an integrated luminosity of 354 pb -1 . The beauty and charm content in events with at least one jet have been extracted using the invariant mass of charged tracks associated with secondary vertices and the decay-length significance of these vertices. Differential cross sections as a function of Q 2 , Bjorken x, jet transverse energy and pseudorapidity were measured and compared with next-to-leading-order QCD calculations. The beauty and charm contributions to the proton structure functions were extracted from the double-differential cross section as a function of x and Q 2 . The running beauty-quark mass, m b at the scale m b , was determined from a QCD fit at next-to-leading order to HERA data for the first time and found to be m b (m b )=4.07±0.14(fit) +0.01 -0.07 (mod.) +0.05 -0.00 (param.) +0.08 -0.05 (theo) GeV.

Leem, So Yeon

2017-10-01

New beauty ideals and particular types of plastic surgery beauty have emerged in South Korea from the early twenty-first century. By defining Gangnam-style plastic surgery as a hybrid of old Westernized beauty ideals and a new science of beauty with variations and contradictions, I intend to twist the simplistic understanding of non-Western plastic surgery as an effort to resemble the white westerner's body. I also draw political implications from a case of monstrous Gangnam-style beauty made by excessive plastic surgery.

Review of charm and beauty lifetimes

International Nuclear Information System (INIS)

Cheung, Harry W. K.

1999-01-01

A review of the latest experimental results on charm and beauty particle lifetimes is presented together with a brief summary of measurement methods used for beauty particle lifetime measurements. There have been significant updates to the D s + /D 0 , B + /B d 0 and Λ b 0 /B d 0 lifetime ratios which have some theoretical implications. However more precise measurements are still needed before one can make conclusive statements about the theory used to calculate the particle lifetimes

The diagnostic boundaries of sleep disorders are under considerable debate. The main sleep disorders are partly heritable; therefore, defining heritable pathophysiologic mechanisms could delineate diagnoses and suggest treatment. We collected clinical data and DNA from consenting patients scheduled to undergo clinical polysomnograms, to expand our understanding of the polymorphisms associated with the phenotypes of particular sleep disorders. Patients at least 21 years of age were recruited to contribute research questionnaires, and to provide access to their medical records, saliva for deoxyribonucleic acid (DNA), and polysomnographic data. From these complex data, 38 partly overlapping phenotypes were derived indicating complaints, subjective and objective sleep timing, and polysomnographic disturbances. A custom chip was used to genotype 768 single-nucleotide polymorphisms (SNPs). Additional assays derived ancestry-informative markers (eg, 751 participants of European ancestry). Linear regressions controlling for age, gender, and ancestry were used to assess the associations of each phenotype with each of the SNPs, highlighting those with Bonferroni-corrected significance. In peroxisome proliferator-activated receptor gamma, coactivator 1 beta (PPARGC1B), rs6888451 was associated with several markers of obstructive sleep apnea. In aryl hydrocarbon receptor nuclear translocator-like (ARNTL), rs10766071 was associated with decreased polysomnographic sleep duration. The association of rs3923809 in BTBD9 with periodic limb movements in sleep was confirmed. SNPs in casein kinase 1 delta (CSNK1D rs11552085), cryptochrome 1 (CRY1 rs4964515), and retinoic acid receptor-related orphan receptor A (RORA rs11071547) were less persuasively associated with sleep latency and time of falling asleep. SNPs associated with several sleep phenotypes were suggested, but due to risks of false discovery, independent replications are needed before the importance of these associations

Evolutionary Effect on the Embodied Beauty of Landscape Architectures.

Zhang, Wei; Tang, Xiaoxiang; He, Xianyou; Chen, Guangyao

2018-01-01

According to the framework of evolutionary aesthetics, a sense of beauty is related to environmental adaptation and plasticity of human beings, which has adaptive value and biological foundations. Prior studies have demonstrated that organisms derive benefits from the landscape. In this study, we investigated whether the benefits of landscape might elicit a stronger sense of beauty and what the nature of this sense of beauty is. In two experiments, when viewing classical landscape and nonlandscape architectures photographs, participants rated the aesthetic scores (Experiment 1) and had a two-alternative forced choice aesthetic judgment by pressing the reaction button located near to (15 cm) or far from (45 cm) the presenting stimuli (Experiment 2). The results showed that reaction of aesthetic ratings for classical landscape architectures was faster than those of classical nonlandscape architectures. Furthermore, only the reaction of beautiful judgment of classical landscape architecture photograph was significantly faster when the reaction button was in the near position to the presenting photograph than those in the position of far away from the presenting photograph. This finding suggests a facilitated effect for the aesthetic perception of classical landscape architectures due to their corresponding components including water and green plants with strong evolutionary implications. Furthermore, this sense of beauty for classical landscape architectures might be the embodied approach to beauty based on the viewpoint of evolutionary aesthetics and embodied cognition.

We discuss the beautiful meson from the point of view of the QCD spectral sum rules (QSSR). The bottom quark mass and the mixed light quark-gluon condensates are determined quite accurately. The decay constant f B is estimated and we present some arguments supporting this result. The decay constants and the masses of the other members of the beautiful meson family are predicted. (orig.)

Measurement of beauty production from dimuon events at HERA

International Nuclear Information System (INIS)

2009-01-01

Beauty production in events containing two muons in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb -1 . A low transverse-momentum threshold for muon identification, in combination with the large rapidity coverage of the ZEUS muon system, gives access to almost the full phase space for beauty production. The total cross section for beauty production in ep collisions at (s) 1/2 = 318 GeV has been measured to be σ tot (ep → b b-bar X) = 13.9 ± 1.5(stat.) +4.0 -4.3 (syst.) nb. Differential cross sections and a measurement of b b-bar correlations are also obtained, and compared to other beauty cross-section measurements, Monte Carlo models and next-to-leading-order QCD predictions.

We hypothesized that DNA methylation patterns may contribute to disease severity or the development of hypertension and excessive daytime sleepiness (EDS) in patients with obstructive sleep apnea (OSA). Illumina's (San Diego, CA, USA) DNA methylation 27-K assay was used to identify differentially methylated loci (DML). DNA methylation levels were validated by pyrosequencing. A discovery cohort of 15 patients with OSA and 6 healthy subjects, and a validation cohort of 72 patients with sleep disordered breathing (SDB). Microarray analysis identified 636 DMLs in patients with OSA versus healthy subjects, and 327 DMLs in patients with OSA and hypertension versus those without hypertension. In the validation cohort, no significant difference in DNA methylation levels of six selected genes was found between the primary snoring subjects and OSA patients (primary outcome). However, a secondary outcome analysis showed that interleukin-1 receptor 2 (IL1R2) promoter methylation (-114 cytosine followed by guanine dinucleotide sequence [CpG] site) was decreased and IL1R2 protein levels were increased in the patients with SDB with an oxygen desaturation index > 30. Androgen receptor (AR) promoter methylation (-531 CpG site) and AR protein levels were both increased in the patients with SDB with an oxygen desaturation index > 30. Natriuretic peptide receptor 2 (NPR2) promoter methylation (-608/-618 CpG sites) were decreased, whereas levels of both NPR2 and serum C type natriuretic peptide protein were increased in the SDB patients with EDS. Speckled protein 140 (SP140) promoter methylation (-194 CpG site) was increased, and SP140 protein levels were decreased in the patients with SDB and EDS. IL1R2 hypomethylation and AR hypermethylation may constitute an important determinant of disease severity, whereas NPR2 hypomethylation and SP140 hypermethylation may provide a biomarker for vulnerability to EDS in OSA.

Neural correlates of visual aesthetics--beauty as the coalescence of stimulus and internal state.

Science.gov (United States)

Jacobs, Richard H A H; Renken, Remco; Cornelissen, Frans W

2012-01-01

How do external stimuli and our internal state coalesce to create the distinctive aesthetic pleasures that give vibrance to human experience? Neuroaesthetics has so far focused on the neural correlates of observing beautiful stimuli compared to neutral or ugly stimuli, or on neural correlates of judging for beauty as opposed to other judgments. Our group questioned whether this approach is sufficient. In our view, a brain region that assesses beauty should show beauty-level-dependent activation during the beauty judgment task, but not during other, unrelated tasks. We therefore performed an fMRI experiment in which subjects judged visual textures for beauty, naturalness and roughness. Our focus was on finding brain activation related to the rated beauty level of the stimuli, which would take place exclusively during the beauty judgment. An initial whole-brain analysis did not reveal such interactions, yet a number of the regions showing main effects of the judgment task or the beauty level of stimuli were selectively sensitive to beauty level during the beauty task. Of the regions that were more active during beauty judgments than roughness judgments, the frontomedian cortex and the amygdala demonstrated the hypothesized interaction effect, while the posterior cingulate cortex did not. The latter region, which only showed a task effect, may play a supporting role in beauty assessments, such as attending to one's internal state rather than the external world. Most of the regions showing interaction effects of judgment and beauty level correspond to regions that have previously been implicated in aesthetics using different stimulus classes, but based on either task or beauty effects alone. The fact that we have now shown that task-stimulus interactions are also present during the aesthetic judgment of visual textures implies that these areas form a network that is specifically devoted to aesthetic assessment, irrespective of the stimulus type.

Face Attractiveness versus Artistic Beauty in Art Portraits: A Behavioral Study

Directory of Open Access Journals (Sweden)

Katharina Schulz

2017-12-01

Full Text Available From art portraits, the observer may derive at least two different hedonic values: The attractiveness of the depicted person and the artistic beauty of the image that relates to the way of presentation. We argue that attractiveness is a property that is predominantly driven by perceptual processes, while the perception of artistic beauty is based predominantly on cognitive processing. To test this hypothesis, we conducted two behavioral experiments. In a gist study (Experiment 1, we showed that ratings on attractiveness were higher after short-term presentation (50 ms than after long-term presentation (3000 ms, while the opposite pattern was found for artistic beauty. In an experiment on perceptual contrast (Experiment 2, we showed that the perceptual contrast effect was stronger for attractiveness than for artistic beauty. These results are compatible with our hypothesis that appreciation of artistic beauty is cognitively modulated at least in part, while processing of attractiveness is predominantly driven perceptually. This dichotomy between cognitive and perceptual processing of different kinds of beauty suggests the participation of different neuronal mechanisms.

Health and Retirement Study participants (n = 8090), aged 65+ with DNA and multiple biennial cognitive observations (abbreviated Telephone Interview for Cognitive Status), were included. Participants were grouped into quartiles of NSES and sleep quality scores. We adjusted for apolipoprotein E ε4, demographic, and cardiovascular risk factors. Random effects modeling evaluated cognitive change over time. NSES and sleep were significantly associated with cognitive decline, and there was a significant interaction between them (P = .02). Significant differences between high/low NSES and high/low sleep quality (P Sleep and NSES were associated with cognitive decline; the association between sleep and cognition appeared stronger among those with low NSES. The association between low NSES, poor sleep quality, and cognitive decline was roughly equivalent to the association between apolipoprotein E ε4 and cognitive decline.

Sleep is not just for the brain: transcriptional responses to sleep in peripheral tissues

Science.gov (United States)

2013-01-01

Background Many have assumed that the primary function of sleep is for the brain. We evaluated the molecular consequences of sleep and sleep deprivation outside the brain, in heart and lung. Using microarrays we compared gene expression in tissue from sleeping and sleep deprived mice euthanized at the same diurnal times. Results In each tissue, nearly two thousand genes demonstrated statistically significant differential expression as a function of sleep/wake behavioral state. To mitigate the influence of an artificial deprivation protocol, we identified a subset of these transcripts as specifically sleep-enhanced or sleep-repressed by requiring that their expression also change over the course of unperturbed sleep. 3% and 6% of the assayed transcripts showed “sleep specific” changes in the lung and heart respectively. Sleep specific transcripts in these tissues demonstrated highly significant overlap and shared temporal dynamics. Markers of cellular stress and the unfolded protein response were reduced during sleep in both tissues. These results mirror previous findings in brain. Sleep-enhanced pathways reflected the unique metabolic functions of each tissue. Transcripts related to carbohydrate and sulfur metabolic processes were enhanced by sleep in the lung, and collectively favor buffering from oxidative stress. DNA repair and protein metabolism annotations were significantly enriched among the sleep-enhanced transcripts in the heart. Our results also suggest that sleep may provide a Zeitgeber, or synchronizing cue, in the lung as a large cluster of transcripts demonstrated systematic changes in inter-animal variability as a function of both sleep duration and circadian time. Conclusion Our data support the notion that the molecular consequences of sleep/wake behavioral state extend beyond the brain to include peripheral tissues. Sleep state induces a highly overlapping response in both heart and lung. We conclude that sleep enhances organ specific

Markers of cellular stress and the unfolded protein response were reduced during sleep in both tissues. These results mirror previous findings in brain. Sleep-enhanced pathways reflected the unique metabolic functions of each tissue. Transcripts related to carbohydrate and sulfur metabolic processes were enhanced by sleep in the lung, and collectively favor buffering from oxidative stress. DNA repair and protein metabolism annotations were significantly enriched among the sleep-enhanced transcripts in the heart. Our results also suggest that sleep may provide a Zeitgeber, or synchronizing cue, in the lung as a large cluster of transcripts demonstrated systematic changes in inter-animal variability as a function of both sleep duration and circadian time. Our data support the notion that the molecular consequences of sleep/wake behavioral state extend beyond the brain to include peripheral tissues. Sleep state induces a highly overlapping response in both heart and lung. We conclude that sleep enhances organ specific molecular functions and that it has a

The main focus of ATLAS b physics has traditionally been on the standard model. In the last few years also the aspects of new physics in B-decays has been addressed. Another new field of studies started recently is a beauty production. We give an overview of the older as well as more recent results. After an introduction outlining selected trigger and detector performance characteristics, we explain methods and goals of CP violation measurements in decay channels of B d 0 meson, physics of B s 0 system and of rare decays. Finally, the ATLAS program for beauty production measurements is presented. (author)

Can We Model the Scenic Beauty of an Alpine Landscape?

Directory of Open Access Journals (Sweden)

Erich Tasser

2013-03-01

Full Text Available During the last decade, agriculture has lost its importance in many European mountain regions and tourism, which benefits from attractive landscapes, has become a major source of income. Changes in landscape patterns and elements might affect scenic beauty and therefore the socio-economic welfare of a region. Our study aimed at modeling scenic beauty by quantifying the influence of landscape elements and patterns in relationship to distance. Focusing on Alpine landscapes in South and North Tyrol, we used a photographic questionnaire showing different landscape compositions. As mountain landscapes offer long vistas, we related scenic beauty to different distance zones. Our results indicate that the near zone contributes by 64% to the valuation of scenic beauty, the middle zone by 22%, and the far zone by 14%. In contrast to artificial elements, naturalness and diversity increased scenic beauty. Significant differences between different social groups (origin, age, gender, cultural background occurred only between the local population and tourists regarding great landscape changes. Changes towards more homogenous landscapes were perceived negatively, thus political decision makers should support the conservation of the cultural landscape.

An attempt at the direct observation of the cascade decay of beauty particles, produced by π - of 350 GeV/c leading to 3 muons or 4 muons in the final state, has been made in an emulsion/counter hybrid experiment at CERN. Under the assumption that the lifetime of beauty particles is of the order of 10 - 13 s the non-observation of any candidates provides an upper limit for beauty production of approx.=90 nb at the 90% confidence level.

Neural Correlates of Visual Aesthetics – Beauty as the Coalescence of Stimulus and Internal State

Science.gov (United States)

Jacobs, Richard H. A. H.; Renken, Remco; Cornelissen, Frans W.

2012-01-01

How do external stimuli and our internal state coalesce to create the distinctive aesthetic pleasures that give vibrance to human experience? Neuroaesthetics has so far focused on the neural correlates of observing beautiful stimuli compared to neutral or ugly stimuli, or on neural correlates of judging for beauty as opposed to other judgments. Our group questioned whether this approach is sufficient. In our view, a brain region that assesses beauty should show beauty-level-dependent activation during the beauty judgment task, but not during other, unrelated tasks. We therefore performed an fMRI experiment in which subjects judged visual textures for beauty, naturalness and roughness. Our focus was on finding brain activation related to the rated beauty level of the stimuli, which would take place exclusively during the beauty judgment. An initial whole-brain analysis did not reveal such interactions, yet a number of the regions showing main effects of the judgment task or the beauty level of stimuli were selectively sensitive to beauty level during the beauty task. Of the regions that were more active during beauty judgments than roughness judgments, the frontomedian cortex and the amygdala demonstrated the hypothesized interaction effect, while the posterior cingulate cortex did not. The latter region, which only showed a task effect, may play a supporting role in beauty assessments, such as attending to one's internal state rather than the external world. Most of the regions showing interaction effects of judgment and beauty level correspond to regions that have previously been implicated in aesthetics using different stimulus classes, but based on either task or beauty effects alone. The fact that we have now shown that task-stimulus interactions are also present during the aesthetic judgment of visual textures implies that these areas form a network that is specifically devoted to aesthetic assessment, irrespective of the stimulus type.

BEAUTY'99 Conference Summary

Eerola, Paula

2000-01-01

Investigations of B hadrons are expected to break new ground in measuring CP-violation effects. This series of BEAUTY conferences, originating from the 1993 conference in Liblice, has contributed significantly in developing ideas of CP-violation measurements using B hadrons and formulating and comparing critically the B-physics experiments. In the '99 conference in Bled we saw the ripening of the field and the first fruit emerging - Tevatron have produced beautiful B-physics results and more are expected to come with the next run, while the B-physics experiments at DESY, SLAC and KEK are starting their operation. The longer-term projects at LHC and Tevatron have taken their shape and detailed prototyping work is going on. Meanwhile, on the phenomenological side, there has been impressive theoretical progress in understanding deeper the 'standard' measurements and proposing new signatures. In this summary, I will highlight the status of the field as presented in the conference, concentrating on signatures, experiments and R and D programmes

Here we present the results of the 6th biennial optical interferometry imaging beauty contest. Taking advantage of a unique opportunity, the red supergiant VY CMa and the Mira variable R Car were observed in the astronomical H-band with three 4-telescope configurations of the VLTI-AT array using the PIONIER instrument. The community was invited to participate in the subsequent image reconstruction and interpretation phases of the project. Ten groups submitted entries to the beauty contest, and we found reasonable consistency between images obtained from independent workers using quite different algorithms. We also found that significant differences existed between the submitted images, much greater than in past beauty contests that were all based on simulated data. A novel crowd-sourcing" method allowed consensus median images to be constructed, filtering likely artifacts and retaining real features." We definitively detect strong spots on the surfaces of both stars as well as distinct circumstellar shells of emission (likely water/CO) around R Car. In a close contest, Joel Sanchez (IAA-CSIC/Spain) was named the winner of the 2014 interferometric imaging beauty contest. This process has shown that new comers" can use publicly-available imaging software to interpret VLTI/PIONIER imaging data, as long as sufficient observations are taken to have complete uv coverage { a luxury that is often missing. We urge proposers to request adequate observing nights to collect sufficient data for imaging and for time allocation committees to recognise the importance of uv coverage for reliable interpretation of interferometric data. We believe that the result of the proposed broad international project will contribute to inspiring trust in the image reconstruction processes in optical interferometry.

Lifetimes of charm and beauty hadrons

International Nuclear Information System (INIS)

Bellini, G.; Dornan, P.J.

1997-01-01

Major breakthroughs have been achieved in the determination of the lifetimes of charm and beauty hadrons. Much larger data samples than previously have become available and new experimental devices and techniques have been developed and employed. The lifetimes of all weakly decaying singly charmed hadrons have been measured, some with an accuracy of a few percent. The difference in the shortest lifetime - τ(Ω c ) - and the longest one - τ(D + ) - is given by a factor of close to ten. The experimental status of beauty lifetimes, while less complete, has still reached a new level of quality and is now better than 5% for the commoner states. New theoretical tools, based mainly on heavy quark expansions, have been developed; they incorporate as well as transcend earlier phenomenological descriptions. The observed pattern in the charm lifetime ratios is reproduced in a semi-quantitative manner as well as could be expected; as far as the beauty lifetime ratios are concerned some problems may well be emerging. The maturity level achieved in the measurements bodes quite well for future challenges where reliable and efficient tracking of the decay vertices will be crucial. (orig.)

Self Representation Among Dark Skin People Concerning Discourse of Beauty

Hasty Larasati

2018-03-01

Full Text Available This article aims to see how’s dark skin people perceive the color of their skin either it’s beautiful or ugly. Up until now, being beautiful categorized as those with fair skin, including Indonesian. This is important to be seen because how you represent yourself related to your identity− who you are or how do you want to be seen. Either they are confident with their skin or not, it is their way of self representation which they got from identity negotiation. But, among dark skin people there always be people who confidently represents their identity against the beauty discourse or counter-discourse. Previous literature reviews show there are two reason can cause counter-discourse: recognition and negotiation. Recognition is an act actor does to fight the mainstream discourse, meanwhile negotiation is about negotiating about what they have. My argument here is women can counter the discourse because of negotiation, they have free choice and body autonomy. Also, they have power to counter the discourse by bargaining power. This article uses qualitative research with in-depth interview towards nine female informants with spesific range of age: 16 – 24 because those ages are ages with huge internet usage. Skin tone classification for informant selection is based on Fitzpatrick skin type scale. Research findings show seven from nine informants have done counter the beauty discourse. Informants also explained how their personality or skills could be their bargaining power which made them easier to counter the beauty discourse. Beside that, informant also have done negotiate their identity from accepted the beauty discourse about desirable skin tones, into counter it. The process did not come out of the blue, but also it need both internal and external factors role. Internal factor is self-consciousness about beauty itself while external factors from family, peer or media socialization.

First look at beauty and beauty-jet tagging via secondary vertexing with ALICE in p+p collisions at √S = 7 TeV

International Nuclear Information System (INIS)

Kweon, Minjung

2011-01-01

The heavy flavour single electron data from RHIC indicate strong coupling of heavy quarks to the medium. The LHC extends greatly the kinematic range to high transverse momentum which enables new tests of heavy quark jet dynamics. Jets containing beauty hadrons have distinctive properties from other types of jets, which enhance their clear identification. We first introduce a method to preferentially select electrons from beauty hadron decay by reconstructing secondary vertices and show the results of this approach on simulated data. A preliminary look at the heavy flavour electron analysis and the beauty analysis in p+p collisions at √S = 7 TeV is also presented. (author)

How is beauty embodied? According to the viewpoint of embodied cognition, the aesthetic processing of words or pictographs has roots in their referential archetypes. Four experiments tested whether the beauty of referential archetypes was routinely activated during the explicit and implicit aesthetic evaluations of the font structures of concrete Chinese words and pictographs in congruent or incongruent font colour. Results showed font structures of simplified Chinese words and pictographs were judged to be more beautiful when they referred to beautiful archetypes; and this pattern was reversed when they referred to ugly archetypes. Moreover, judgement was facilitated when font colour was congruent for Chinese words and pictographs referred to beautiful archetypes. For those referred to ugly archetypes, judgement was inhibited in congruent font colour but facilitated in incongruent font colour, suggesting aesthetic perceptions of the font structures of Chinese words and pictographs were derived from their referential natural objects. The spontaneous generation hypothesis of beauty is proposed to account for these findings. © 2016 International Union of Psychological Science.

Cellular consequences of sleep deprivation in the brain.

Cirelli, Chiara

2006-10-01

Several recent studies have used transcriptomics approaches to characterize the molecular correlates of sleep, waking, and sleep deprivation. This analysis may help in understanding the benefits that sleep brings to the brain at the cellular level. The studies are still limited in number and focus on a few brain regions, but some consistent findings are emerging. Sleep, spontaneous wakefulness, short-term, and long-term sleep deprivation are each associated with the upregulation of hundreds of genes in the cerebral cortex and other brain areas. In fruit flies as well as in mammals, three categories of genes are consistently upregulated during waking and short-term sleep deprivation relative to sleep. They include genes involved in energy metabolism, synaptic potentiation, and the response to cellular stress. In the rat cerebral cortex, transcriptional changes associated with prolonged sleep loss differ significantly from those observed during short-term sleep deprivation. However, it is too early to draw firm conclusions relative to the molecular consequences of sleep deprivation, and more extensive studies using DNA and protein arrays are needed in different species and in different brain regions.

Female adult rats were trained for a two-way active avoidance task (4 h), and allowed free sleep (3 h). Control rats (C) were left in their home cages during the acquisition period. Dural electrodes and an intraventricular cannula, implanted one week in advance, were used for EEG recording during the period of sleep and for the injection of [3H]thymidine at the beginning of the training session, respectively. Rats were killed at the end of the sleep period, and the DNA-specific activity was determined in the main brain regions and in liver. Correlations among sleep, behavioral and biochemical variables were assessed using Spearman's nonparametric method. In learning rats (L), the number of avoidances was negatively correlated with SS-W variables, and positively correlated with SS-PS variables (episodes of synchronized sleep followed by wakefulness or paradoxical sleep, respectively) and with PS variables. An inverse pattern of correlations was shown by the number of escapes or freezings. No correlations occurred in rats unable to achieve the learning criterion (NL). In L rats, the specific activity of brain DNA was negatively correlated with SS-W variables and positively correlated with SS-PS variables, while essentially no correlation concerned PS variables. On the other hand, in NL rats, comparable correlations were positive with SS-W variables and negative with SS-PS and PS variables. Few and weak correlations occurred in C rats. The data support a role of SS in brain information processing, as postulated by the sequential hypothesis on the function of sleep. In addition, they suggest that the elimination of nonadaptive memory traces may require several SS-W episodes and a terminal SS-PS episode. During PS episodes, adaptive memory traces cleared of nonadaptive components may be copied in more suitable brain sites.

Mating motives are neither necessary nor sufficient to create the beauty premium.

Mating motives lead decision makers to favor attractive people, but this favoritism is not sufficient to create a beauty premium in competitive settings. Further, economic approaches to discrimination, when correctly characterized, could neatly accommodate the experimental and field evidence of a beauty premium. Connecting labor economics and evolutionary psychology is laudable, but mating motives do not explain the beauty premium.

Introducing a "Balance" in The BSC Through Beauty and Love

Directory of Open Access Journals (Sweden)

Ari Kamayanti

2010-04-01

Full Text Available Celebrating the seventeenth anniversary of the Balanced Score Card (BSC since it was born in 1992, this paper revisits its concept as one of the landmarks in performance measurement. The BSC turns out to be ‘not so balanced’ since it lacks certain beauty and love. It hinges on accountability for certain interests when measuring performance, negating or putting other interests as minority. Thus, it fits perfectly with the aim of management accounting that puts managers and customers as priorities. The imbalances comes from secularism and overemphasis in rationalism. Sustainability that becomes the current issue nowadays would not be supported by such performance measurement. In order to insert this balance, a methodology by taking a methapor of nurturing mother is applied in this research that encompasses gentle beauty and subtle love. Gentle beauty refers to a complete harmony of beauty : irrational and the rational; this means introducing those that have been left out in the name of rationality such as religions and spiritualism. Subtle love refers to love towards God that is expressed subtly without lust to overpower. The result is a more balanced set of performance measurements that are filled with beauty and love, insyaAllah.

Using deep learning to quantify the beauty of outdoor places.

2017-07-01

Beautiful outdoor locations are protected by governments and have recently been shown to be associated with better health. But what makes an outdoor space beautiful? Does a beautiful outdoor location differ from an outdoor location that is simply natural? Here, we explore whether ratings of over 200 000 images of Great Britain from the online game Scenic-Or-Not , combined with hundreds of image features extracted using the Places Convolutional Neural Network, might help us understand what beautiful outdoor spaces are composed of. We discover that, as well as natural features such as 'Coast', 'Mountain' and 'Canal Natural', man-made structures such as 'Tower', 'Castle' and 'Viaduct' lead to places being considered more scenic. Importantly, while scenes containing 'Trees' tend to rate highly, places containing more bland natural green features such as 'Grass' and 'Athletic Fields' are considered less scenic. We also find that a neural network can be trained to automatically identify scenic places, and that this network highlights both natural and built locations. Our findings demonstrate how online data combined with neural networks can provide a deeper understanding of what environments we might find beautiful and offer quantitative insights for policymakers charged with design and protection of our built and natural environments.

2017-09-01

We previously reported that compared with night sleep, day sleep among shift workers was associated with reduced urinary excretion of 8-hydroxydeoxyguanosine (8-OH-dG), potentially reflecting a reduced ability to repair 8-OH-dG lesions in DNA. We identified the absence of melatonin during day sleep as the likely causative factor. We now investigate whether night work is also associated with reduced urinary excretion of 8-OH-dG. For this cross-sectional study, 50 shift workers with the largest negative differences in night work versus night sleep circulating melatonin levels (measured as 6-sulfatoxymelatonin in urine) were selected from among the 223 shift workers included in our previous study. 8-OH-dG concentrations were measured in stored urine samples using high performance liquid chromatography with electrochemical detection. Mixed effects models were used to compare night work versus night sleep 8-OH-dG levels. Circulating melatonin levels during night work (mean=17.1 ng/mg creatinine/mg creatinine) were much lower than during night sleep (mean=51.7 ng/mg creatinine). In adjusted analyses, average urinary 8-OH-dG levels during the night work period were only 20% of those observed during the night sleep period (95% CI 10% to 30%; psleep, is associated with reduced repair of 8-OH-dG lesions in DNA and that the effect is likely driven by melatonin suppression occurring during night work relative to night sleep. If confirmed, future studies should evaluate melatonin supplementation as a means to restore oxidative DNA damage repair capacity among shift workers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Leder, Johannes; Häusser, Jan Alexander; Mojzisch, Andreas

2013-09-01

Often, economic decisions do not only depend on one's own preferences, but also on the choices of others and therefore require strategizing (i.e., thinking about what others might think). In experimental economics, this has been modeled by the beauty contest game. Another typical feature of economic decisions is that they are often carried out under stress. Therefore, in the present study, we aimed to examine the influence of stress on decision-making in the beauty contest game. Participants were randomly assigned to either the Trier Social Stress Test for Groups (TSST-G) or a placebo version of the TSST-G (control condition). Then, participants played four rounds of a standard beauty contest game. As a biomarker of stress, salivary cortisol was measured. As predicted, participants under stress chose higher numbers in the beauty contest game than non-stressed participants, indicating less strategizing. This effect was mediated by the stress-induced increase in cortisol. Copyright © 2013 Elsevier Ltd. All rights reserved.

Witt, Juliana da Silveira Gonçalves Zanini; Schnider, Aline Petter

2011-09-01

Nowadays, there is an increasing quest for beauty and the models proposed by fashion goods and service segments, to achieve the perfect body. The standard of beauty corresponds to a thin body, without considering health aspects. The number of women who go on diets to control weight is increasing; and taking this into consideration the objective of this study is to conduct a bibliographical review and extract data on esthetics and body image to support the practice of nutritional care. Socio-cultural aspects, which motivate the quest for the perfect body, as well as body, beauty, esthetics, nutritional counseling and cognitive behavior therapy were examined in this survey. On the basis of this work, it is possible to conclude that the continuing obsession with the body may lead the person to go on diets and other drastic methods to control weight, such as surgical procedures. In this respect, nutritional care is far more than merely recommending a standard diet or giving information, as it represents providing an effective model for nutritional reeducation, prioritizing improvement in the style and quality of life. This article provides data about enhancing esthetics and beauty by means of appropriate nutrition.

The Oval Female Facial Shape--A Study in Beauty.

Goodman, Greg J

2015-12-01

Our understanding of who is beautiful seems to be innate but has been argued to conform to mathematical principles and proportions. One aspect of beauty is facial shape that is gender specific. In women, an oval facial shape is considered attractive. To study the facial shape of beautiful actors, pageant title winners, and performers across ethnicities and in different time periods and to construct an ideal oval shape based on the average of their facial shape dimensions. Twenty-one full-face photographs of purportedly beautiful female actors, performers, and pageant winners were analyzed and an oval constructed from their facial parameters. Only 3 of the 21 faces were totally symmetrical, with the most larger in the left upper and lower face. The average oval was subsequently constructed from an average bizygomatic distance (horizontal parameter) of 4.3 times their intercanthal distance (ICD) and a vertical dimension that averaged 6.3 times their ICD. This average oval could be fitted to many of the individual subjects showing a smooth flow from the forehead through temples, cheeks, jaw angle, jawline, and chin with all these facial aspects abutting the oval. Where they did not abut, treatment may have improved these subjects.

A role for clock genes in sleep homeostasis.

Franken, Paul

2013-10-01

The timing and quality of both sleep and wakefulness are thought to be regulated by the interaction of two processes. One of these two processes keeps track of the prior sleep-wake history and controls the homeostatic need for sleep while the other sets the time-of-day that sleep preferably occurs. The molecular pathways underlying the latter, circadian process have been studied in detail and their key role in physiological time-keeping has been well established. Analyses of sleep in mice and flies lacking core circadian clock gene proteins have demonstrated, however, that besides disrupting circadian rhythms, also sleep homeostatic processes were affected. Subsequent studies revealed that sleep loss alters both the mRNA levels and the specific DNA-binding of the key circadian transcriptional regulators to their target sequences in the mouse brain. The fact that sleep loss impinges on the very core of the molecular circadian circuitry might explain why both inadequate sleep and disrupted circadian rhythms can similarly lead to metabolic pathology. The evidence for a role for clock genes in sleep homeostasis will be reviewed here. Copyright © 2013 Elsevier Ltd. All rights reserved.

Beauty in photoproduction at HERA II with the ZEUS detector

International Nuclear Information System (INIS)

Boutle, Sarah

2010-02-01

The production of beauty quarks in ep collisions should be accurately calculable in perturbative Quantum Chromodynamics (QCD) since the large mass of the b quark provides a hard scale. Therefore it is interesting to compare such predictions to results using photoproduction events where a low-virtuality photon, emitted by the incoming lepton, collides with a parton from the incoming proton. A measurement of beauty in photoproduction has been made at HERA with the ZEUS detector using an integrated luminosity of 126 pb - 1. Beauty was identified in events with a muon in the final state by using the transverse momentum of the muon relative to the closest jet. Lifetime information from the silicon vertex detector was also used; the impact parameter of the muon with respect to the primary vertex was exploited to discriminate between signal and background. Cross sections for beauty production as a function of the muon and the jet variables were measured and compared to QCD predictions and to previous measurements. The data were found to be well described by the predictions from next-to-leading-order QCD. The dijet sample of beauty photoproduction events was also used to study higher-order QCD topologies. At leading order, the two jets in the event are produced back-to-back in azimuthal angle, such that Δφ jj =φ j1 -φ j2 =π. Additional soft radiation causes small azimuthal decorrelations, whilst Δφ jj significantly lower than π is evidence of additional hard radiation. In this thesis, the cross section versus Δφ jj for beauty photoproduction and the comparison to NLO QCD predictions and Monte Carlo models are presented. (orig.)

Tourists- eyes will often be attracted by the unique phenomenon of the roadsides: betel nut beauties (pronounced as binlang xishi in Mandarin), if they drive on the roads of Taiwan. Sitting in the neon-lit glass stalls with attractive dress on the roadsides, betel nut beauties usually sell betel nuts to the passing truckers or car drivers with much of their efforts. Moreover, in order to attract peoples- eyesight and increase the sales volume, the young girls are in skimp...

Beauty and charm production in fixed target experiments

Kidonakis, Nikolaos; Vogt, Ramona

2004-01-01

We present calculations of NNLO threshold corrections for beauty and charm production in π - p and pp interactions at fixed-target experiments. Recent calculations for heavy quark hadroproduction have included next-to-next-to-leading-order (NNLO) soft-gluon corrections [1] to the double differential cross section from threshold resummation techniques [2]. These corrections are important for near-threshold beauty and charm production at fixed-target experiments, including HERA-B and some of the current and future heavy ion experiments

Beauty industry grows vastly in the scope of regional, national, or international. Beauty industry includes Spa service. It becomes one of the choices where the urban citizen can use it to release their stress and relax their mind. This business grows as the development of technology. Spa industry should be able to provide the best service for physical and mental therapy, it will make the user of the service can be freed from their business and stress in the respective time to be healthies, more beautiful, and able to do their activity maximally. Spa treatment consists of hair creambath, facial treatment, manicure-pedicure, scrub treatment, foot spa, aromatherapy, and body treatment with traditional cosmetics which are easy to get in Indonesia. Beauty education is one of the programs in Home Economics Department of Engineering Faculty of UNNES. This program was established to produce graduates in beauty fields as Vocational High School teachers with bachelor (S1) qualification. The graduates suppose to be excellent, professional, skillful, and care to the environment, culture, and social condition around them. It prepares them as teachers of beauty (in formal and non- formal education). Besides, it also prepared them to have professional competence in production fields of beauty service with adaptive, creative, and innovative which can be entrepreneurs who are able to create job vacancies for others. Beauty education used KKNI- based curriculum, which is oriented to Industry and Working Fields with UNNES' Conservation basis. It provided the students a chance to practive their knowledge in working internship program, study field trip, and teaching practice program. The industry of Spa service provides a big chance to become an entrepreneur, create a working field, and help the government reduce unemployment number, whether from beauty education graduates or from vocational high school students

The effects of atmospheric optical conditions on perceived scenic beauty

Science.gov (United States)

Latimer, Douglas A.; Hogo, Henry; Daniel, Terry C.

This paper describes the results from the first year of a currently on-going study, the objective of which is to investigate the relationships between atmospheric optical conditions and human perceptions of scenic beauty. Color photographs and atmospheric optical measurements, using telephotometers and nephelometers, were taken in the western U.S.A. (Grand Canyon National Park and Mt. Lemmon near Tucson, Arizona) and in the eastern United States (Great Smoky Mountains and Shenandoah national parks). Over 1300 individual observers rated color slides for either visual air quality or scenic beauty using a 10-point rating scale. Ratings were transformed to indices using standard psychophysical techniques. Relationships between these perceptual indices and physical parameters characteristic of the given landscape represented in the color slides were investigated using scatter plots, correlation analysis, and multiple linear regression. Physical parameters included visual range, horizon sky chromaticity and luminance, solar zenith and scattering angles, and cloud conditions. Results show that observers' ratings of visual air quality and scenic beauty are sensitive to visual range, sky color, and scattering angle. However, in some of the areas investigated, scenic beauty ratings were not affected by changes in visual range. The sensitivity of the scenic beauty of a vista to changes in the extinction coefficient may be useful for establishing visibility goals and priorities.

The associated production of a pair of beauty particles B - and anti B 0 by a 350 GeV π - interaction has been observed in an emulsion target inserted in an array of silicon microstrip detectors. Both beauty particles decay into charm particles, both of which are also observed to decay in the emulsion. Two negative muons were identified and their momenta measured in a large muon spectrometer. One muon has a psub(T) of 1.9 GeV/c and is associated with a beauty particle decay. The other, with a psub(T) of 0.45 GeV/c is associated with a charm particle decay. The flight times of the two beauty particles are respectively (0.8+-0.1).10 -13 s and (5sub(-1) +2 ).10 -13 s. Alternative interpretations of this event have negligible probability. (orig.)

Presence, Mourning, and Beauty: Elements of Analytic Process.

Science.gov (United States)

Markman, Henry C

2017-12-01

Analyst and patient occasionally arrive at moments of heightened meaning and aliveness. These moments can be transformative and lead to psychic change in the patient. They give life and arouse hope, and feel "real" in a new way, though often entailing emotional turbulence. Specific internal work must be done by the analyst to allow for and foster these experiences. This involves a kind of mourning process in the analyst that allows for "presence" and "availability" as described by Gabriel Marcel, and for the "at-one-ment" described by Bion. These transforming moments can be viewed in an aesthetic realm, along the lines of Keats's "Beauty is truth, truth beauty." This embodies the analytic value of emotional truth. These moments are shared and their emergence is an intersubjective creation. Clinical illustrations show how the internal work of mourning by the analyst through directed introspection allows for presence and availability, and then for shared moments of beauty with the patient.

Ontological-epistemological views of the beautiful Byzantine aesthetics

Vilić Nataša

2015-01-01

Full Text Available The paper approaches the ontological-epistemology aspects of the beauty of Byzantine art. Byzantine aesthetics and Byzantine art are unjustly neglected in the history of aesthetic thought. Christian aestheticians have an ambivalent attitude towards art. Because, Byzantine painting represents reality show based on the Christians view, where absolutizs a new dimension of spirituality and aesthetics deriving from the ontological-epistemological positions. The phenomenon of beauty in Byzantine art is primarily deposited in epistemological components, where everything is directed to the knowledge of the truth. In Byzantine art beauty has, above all, spiritual character; it does not have a classical aesthetic dimension, but primarily because the ontological character is recognized as one of the innumerable divine energies and of phenomena. The Byzantine painter makes an effort to realize the creative transformation of matter into a unique experience community and relationship with God, who volatility of the world beyond the ontological light that is converted from non-being into being.

Predicting beauty: fractal dimension and visual complexity in art.

Forsythe, A; Nadal, M; Sheehy, N; Cela-Conde, C J; Sawey, M

2011-02-01

Visual complexity has been known to be a significant predictor of preference for artistic works for some time. The first study reported here examines the extent to which perceived visual complexity in art can be successfully predicted using automated measures of complexity. Contrary to previous findings the most successful predictor of visual complexity was Gif compression. The second study examined the extent to which fractal dimension could account for judgments of perceived beauty. The fractal dimension measure accounts for more of the variance in judgments of perceived beauty in visual art than measures of visual complexity alone, particularly for abstract and natural images. Results also suggest that when colour is removed from an artistic image observers are unable to make meaningful judgments as to its beauty. ©2010 The British Psychological Society.

Euler's pioneering equation the most beautiful theorem in mathematics

CERN Document Server

Wilson, Robin

2018-01-01

In 1988 The Mathematical Intelligencer, a quarterly mathematics journal, carried out a poll to find the most beautiful theorem in mathematics. Twenty-four theorems were listed and readers were invited to award each a 'score for beauty'. While there were many worthy competitors, the winner was 'Euler's equation'. In 2004 Physics World carried out a similar poll of 'greatest equations', and found that among physicists Euler's mathematical result came second only to Maxwell's equations. The Stanford mathematician Keith Devlin reflected the feelings of many in describing it as "like a Shakespearian sonnet that captures the very essence of love, or a painting which brings out the beauty of the human form that is far more than just skin deep, Euler's equation reaches down into the very depths of existence."

Spin is a beautiful concept that plays an ever important role in modern physics. In this talk, I start with a discussion of the origin of spin, and then turn to three themes in which spin has been crucial in subatomic physics: a lab to explore physics beyond the standard model, a tool to measure physical observables that are hard to obtain otherwise, a probe to unravel nonperturbative QCD. I conclude with some remarks on a world without spin

The author feels that ''an almost universal idolatry of gigantism'' has caused the urgent crisis of today's society. The book expresses his philosophy of the beauty of thinking in less grandiose terms. He offers some smaller-scale yet highly feasible solutions to many of the problems created by bigness--the environmental crisis, the energy shortage, the dehumanization of industrial workers, the flight from rural areas, and the decay of cities.

A measurement of charm and beauty photoproduction at the electron proton collider HERA is presented based on the simultaneous detection of a D meson and a muon. The correlation between the D meson and the muon serves to separate the charm and beauty contributions and the analysis provides comparable sensitivity to both. The total and differential experimental cross sections are compared to LO and NLO QCD calculations. The measured charm cross section is in good agreement with QCD predictions including higher order effects while the beauty cross section is higher.

Sleeping Beauty Transposition of Chimeric Antigen Receptors Targeting Receptor Tyrosine Kinase-Like Orphan Receptor-1 (ROR1 into Diverse Memory T-Cell Populations.

Directory of Open Access Journals (Sweden)

Drew C Deniger

Full Text Available T cells modified with chimeric antigen receptors (CARs targeting CD19 demonstrated clinical activity against some B-cell malignancies. However, this is often accompanied by a loss of normal CD19+ B cells and humoral immunity. Receptor tyrosine kinase-like orphan receptor-1 (ROR1 is expressed on sub-populations of B-cell malignancies and solid tumors, but not by healthy B cells or normal post-partum tissues. Thus, adoptive transfer of T cells specific for ROR1 has potential to eliminate tumor cells and spare healthy tissues. To test this hypothesis, we developed CARs targeting ROR1 in order to generate T cells specific for malignant cells. Two Sleeping Beauty transposons were constructed with 2nd generation ROR1-specific CARs signaling through CD3ζ and either CD28 (designated ROR1RCD28 or CD137 (designated ROR1RCD137 and were introduced into T cells. We selected for T cells expressing CAR through co-culture with γ-irradiated activating and propagating cells (AaPC, which co-expressed ROR1 and co-stimulatory molecules. Numeric expansion over one month of co-culture on AaPC in presence of soluble interleukin (IL-2 and IL-21 occurred and resulted in a diverse memory phenotype of CAR+ T cells as measured by non-enzymatic digital array (NanoString and multi-panel flow cytometry. Such T cells produced interferon-γ and had specific cytotoxic activity against ROR1+ tumors. Moreover, such cells could eliminate ROR1+ tumor xenografts, especially T cells expressing ROR1RCD137. Clinical trials will investigate the ability of ROR1-specific CAR+ T cells to specifically eliminate tumor cells while maintaining normal B-cell repertoire.

The Golden Beauty: Brain Response to Classical and Renaissance Sculptures

Is there an objective, biological basis for the experience of beauty in art? Or is aesthetic experience entirely subjective? Using fMRI technique, we addressed this question by presenting viewers, naïve to art criticism, with images of masterpieces of Classical and Renaissance sculpture. Employing proportion as the independent variable, we produced two sets of stimuli: one composed of images of original sculptures; the other of a modified version of the same images. The stimuli were presented in three conditions: observation, aesthetic judgment, and proportion judgment. In the observation condition, the viewers were required to observe the images with the same mind-set as if they were in a museum. In the other two conditions they were required to give an aesthetic or proportion judgment on the same images. Two types of analyses were carried out: one which contrasted brain response to the canonical and the modified sculptures, and one which contrasted beautiful vs. ugly sculptures as judged by each volunteer. The most striking result was that the observation of original sculptures, relative to the modified ones, produced activation of the right insula as well as of some lateral and medial cortical areas (lateral occipital gyrus, precuneus and prefrontal areas). The activation of the insula was particularly strong during the observation condition. Most interestingly, when volunteers were required to give an overt aesthetic judgment, the images judged as beautiful selectively activated the right amygdala, relative to those judged as ugly. We conclude that, in observers naïve to art criticism, the sense of beauty is mediated by two non-mutually exclusive processes: one based on a joint activation of sets of cortical neurons, triggered by parameters intrinsic to the stimuli, and the insula (objective beauty); the other based on the activation of the amygdala, driven by one's own emotional experiences (subjective beauty).

Cross sections for beauty production as a function of the muon and the jet variables were measured and compared to QCD predictions and to previous measurements. The data were found to be well described by the predictions from next-to-leading-order QCD. The dijet sample of beauty photoproduction events was also used to study higher-order QCD topologies. At leading order, the two jets in the event are produced back-to-back in azimuthal angle, such that {delta}{phi}{sup jj}={phi}{sup j1}-{phi}{sup j2}={pi}. Additional soft radiation causes small azimuthal decorrelations, whilst {delta}{phi}{sup jj} significantly lower than {pi} is evidence of additional hard radiation. In this thesis, the cross section versus {delta}{phi}{sup jj} for beauty photoproduction and the comparison to NLO QCD predictions and Monte Carlo models are presented. (orig.)

Measurement of beauty production at HERA using events with muons and jets

2005-01-01

Several new measurements of beauty production at HERA have been presented at this conference. In this talk we report about the H1 measurement using events with a muon associated to a jet. This is the first beauty analysis at HERA, where both the long lifetime and the large mass of b-flavoured hadrons are exploited to identify the beauty events, leading to an improved signal separation. Differential cross sections are measured both in photoproduction and in deep inelastic scattering. The measured data are found to be somewhat higher then perturbative QCD calculations to next-to-leading order. A significant excess is observed in certain corners of the kinematic phase space. At the end of this report new and recent beauty measurements are summarised

J/ψ and ψ ' mesons are identified through their decays into muon pairs and are selected in the Feynman-x range x F >0. Inclusive J/ψ and ψ ' cross-sections and J/ψ differential cross-sections as functions of x F and p T are measured. A fit to the data for different targets gives α(J/ψ){Si,Cu,W}=0.87±0.05 (stat.)±0.04 (syst.), σ 0 (J/ψ)=(216.2±5.4 (stat.)±13.3 (syst.)) nb/nucleon and σ 0 (ψ ' )=(28.3±8.1(stat.)±11.3 (syst.)) nb/nucleon. For the study of beauty production, we have identified 26 beauty events. The estimated background in this sample is 0.6±0.6 events. From these data, assuming a linear A-dependence, we measure a beauty production cross-section integrated over all x F of 5.7 -1.1 +1.3 (stat.) -0.5 +0.6 (syst.) nb/N. Differential distributions with respect to x F and p T 2 have been determined as well as some two-particle kinematic variables. Our results are compared with previous experiments and with a next-to-leading-order QCD calculation

Asymmetry and Symmetry in the Beauty of Human Faces

Directory of Open Access Journals (Sweden)

Marjan Hessamian

2010-02-01

Full Text Available The emphasis in the published literature has mostly been on symmetry as the critical source for beauty judgment. In fact, both symmetry and asymmetry serve as highly aesthetic sources of beauty, whether the context is perceptual or conceptual. The human brain is characterized by symbolic cognition and this type of cognition facilitates a range of aesthetic reactions. For example, both art and natural scenery contain asymmetrical elements, which nevertheless render the whole effect beautiful. A further good case in point is, in fact, human faces. Normally, faces are structurally left-right symmetrical content-wise but not size-wise or function-wise. Attractiveness has often been discussed in terms of content-wise full-face symmetry. To test whether or not attractiveness can be gleaned only from the presence of left-right full-faces we tested half faces. Three separate groups of participants viewed and rated the attractiveness of 56 full-faces (women’s and men’s, their 56 vertical left hemi-faces and 56 vertical right hemi-faces. We found no statistically significant differences in the attractiveness ratings of full- and hemi-faces (whether left or right. Instead, we found a strong and significant positive correlation between the ratings of the hemi- and full-faces. These results are consistent with the view that the underpinning of human facial beauty is complex and that bilateral symmetry does not constitute a principle factor in beauty assessment. We discuss that the highly evolved human brain, compared to other animals, as well as symbolic and abstract cognition in humans enable a wide variety of aesthetic reactions.

Three different, but related topics are the subject of this thesis, performed in the contextof the ZEUS and CMS groups at DESY. The first measurement of the MS beauty-quarkmass mb (mb ) at an electron-proton collider is presented. The measurement is based ona QCD analysis of beauty production cross sections in deep inelastic (DIS) ep scatteringmeasured by ZEUS at HERA, together with inclusive DIS HERA data, using Next-toLeading-Order QCD predictions. The measured value of the running beauty-quark massin the MS scheme was found to bemb (mb ) = 4.07 ± 0.14 (fit)+0.01 (mod.)+0.05 (param.) +0.08 (theo.)

The realization of absolute beauty: an interpretation of the fairytale Snow White.

Science.gov (United States)

Takenaka, Nanae

2016-09-01

This paper interprets the fairytale Snow White (Bruder Grimm 1857) in terms of the realization of absolute beauty. Jung's understanding that 'in myths and fairytales, as in dreams, the soul speaks about itself' (Jung 1945, para. 400), underpins such an approach. From this perspective a fantasy image is not about us, not about our unconsciousness, but is essentially about itself. The idea of absolute beauty first arises in the Queen's mind as a wish. Despite the Queen's strong desire to be named as the most beautiful person in the world, her mirror reflects that it is actually her daughter Snow White who is the fairest. Snow White might be regarded in the language of Giegerich as her internal other. Effectively they are separated into the Real that conceives the idea of absolute beauty and the Ideal that embodies it. The exchange that takes place between the two - mediated by mirror and window - generates the corpse of surpassing beauty that never decays but lies inaccessible behind the glass coffin. However the loving and penetrating gaze of the Prince, representing masculinity, succeeds in reanimating Snow White. Thus the Prince as the Other that is completely external and unknown to both the Queen and Snow White, specifically to their femininity, facilitates the realization of absolute beauty as the Ideal in the Real. © 2016, The Society of Analytical Psychology.

Beauty photoproduction using decays into electrons at HERA

2008-05-15

Photoproduction of beauty quarks in events with two jets and an electron associated with one of the jets has been studied with the ZEUS detector at HERA using an integrated luminosity of 120 pb{sup -1}. The fractions of events containing b quarks, and also of events containing c quarks, were extracted from a likelihood fit using variables sensitive to electron identification as well as to semileptonic decays. Total and differential cross sections for beauty and charm production were measured and compared with next-to-leading-order QCD calculations and Monte Carlo models. (orig.)

We give here a detailed description of experiment WA75, which was performed at CERN to search for beauty particles. Events containing at least one muon with a high momentum transverse to the beam direction were selected; then the primary interactions and decay vertices, located in stacks of nuclear research emulsions, were examined and analysed. The various parts of the apparatus are described and the off-line analysis and search in emulsion are discussed. An estimate is made of the sensitivity of the experiment to beauty- and charmed-particle production. (orig.)

Dysregulation of sleep or feeding has enormous health consequences. In humans, acute sleep loss is associated with increased appetite and insulin insensitivity, while chronically sleep-deprived individuals are more likely to develop obesity, metabolic syndrome, type II diabetes, and cardiovascular disease. Conversely, metabolic state potently modulates sleep and circadian behavior; yet, the molecular basis for sleep-metabolism interactions remains poorly understood. Here, we describe the identification of translin (trsn), a highly conserved RNA/DNA binding protein, as essential for starvation-induced sleep suppression. Strikingly, trsn does not appear to regulate energy stores, free glucose levels, or feeding behavior suggesting the sleep phenotype of trsn mutant flies is not a consequence of general metabolic dysfunction or blunted response to starvation. While broadly expressed in all neurons, trsn is transcriptionally upregulated in the heads of flies in response to starvation. Spatially restricted rescue or targeted knockdown localizes trsn function to neurons that produce the tachykinin family neuropeptide Leucokinin. Manipulation of neural activity in Leucokinin neurons revealed these neurons to be required for starvation-induced sleep suppression. Taken together, these findings establish trsn as an essential integrator of sleep and metabolic state, with implications for understanding the neural mechanism underlying sleep disruption in response to environmental perturbation.

Hollywood’s Terror Industry: Idealized beauty and The Bluest Eye

Directory of Open Access Journals (Sweden)

E C Koch

2014-07-01

Full Text Available Toni Morrison’s novel The Bluest Eye (1970 examines the effects of 1940s American white cultural hegemony on her black characters: Claudia, Pauline, and Pecola. The dominant influence of white society, specifically white ideals of beauty, are perpetuated through film, and exemplified by such actresses as Shirley Temple and Greta Garbo. The terrifying nature of the Hollywood ideal is borne from its influence and ubiquity, and is highlighted by Pecola’s deranged pursuit of this impossible standard of beauty. Ultimately by attempting to realize this paradigm, blacks are disenfranchised while the ideal is recharged with the power of those who continue to pursue it.

The Super Fixed Target beauty facility at the SSC

International Nuclear Information System (INIS)

Lau, Kwong

1991-01-01

The rationale for pursuing beauty physics at the SSC in a fixed target configuration is described. The increased beauty production cross section at the SSC, combined with high interaction rate capability of the proposed detector, results in 10 10-11 produced BB events per year. The long decay length of the B hadrons (≅ 10 cm) allows direct observation of B decays in the high resolution silicon microstrip vertex detector. To optimize the operation of the proposed beauty spectrometer and the SSC, parasitic extraction of attendant or artificially generated large amplitude protons using crystal channeling is proposed and explored. The large sample of fully reconstructed B events allows detailed studies of various CP violating decays with requisite statistics to confront the standard model. The CP physics potential of the proposed experiment is evaluated and compared with alternative approaches, such as symmetric e + e - B Factories and specialized hadron colliders

Chronic sleep restriction may affect metabolism, hormone secretion patterns and inflammatory responses. Limited reports suggest also epigenetic effects, such as changes in DNA methylation profiles. The study aims to assess the potential association between poor sleep quality or sleep duration and the levels of 5-methylcytosine in the promoter regions of selected tumor suppressor genes. A cross-sectional study was conducted on 710 nurses and midwives aged 40-60 years. Data from interviews regarding sleep habits and potential confounders were used. The methylation status of tumor suppressor genes was determined via qMSP reactions using DNA samples derived from leucocytes. No significant findings were observed in the total study population or in the two subgroups of women stratified by the current system of work. A borderline significance association was observed between a shorter duration of sleep and an increased methylation level in CDKN2A among day working nurses and midwives. Further studies are warranted to explore this under-investigated topic.

Competing motivational discourses for weight loss: means to ends and the nexus of beauty and health.

Kwan, Samantha

2009-09-01

Western cultural discourses generally deem fat unhealthy and unattractive, providing strong motivation for body nonconformists to lose weight. Semistructured interviews with 42 overweight and obese participants illuminate how individuals understand health and beauty weight-loss motivations and the relationship between the two. Interviews indicate that health and beauty motivate because they are seen as means to various ends. Specifically, participants aspire to health to fulfill various social roles and to live long, meaningful lives. Moreover, they aspire to conventional beauty ideals hoping that aesthetic conformity will elicit benefits, both psychological and social. Interviews also illustrate an intertwining of discourses in which participants conflate beauty and health in three ways: indicating that depictions of the beauty ideal are depictions of the health ideal; using beauty indicators as health indicators; and employing beauty as a motivator for health goals. This article concludes with a discussion of the health, social, and policy implications of these findings.

This painting is recognized all over the world as an intangible cultural heritage of humanity in the context of its philosophical principles. Petrykivsky decorative painting by its basis — murals,  reaches Tripoli and puts the Ukrainian culture among the ancient cultures of the world. At various stages of ethnos’ existence, Ukrainian folk decorative art was an important part of the spiritual life and reflected its identity, ensuring the continuity of spiritual connection between generations. Motives of Petrykivka decorative painting describe the local flora and fauna and the local historical tradition. Folk artists get their inspiration from the mother nature, traditional for the Ukrainian people worship to Mother-land and all beautiful things, which are created by it. However, Petrykivsky decorative painting is not a direct reflection of natural motifs. World, created in paintings, is the product of the imagination of folk artist.

A measurement of charm and beauty photoproduction at the electron proton collider HERA is presented based on the simultaneous detection of a D*^{\\pm} meson and a muon. The correlation between the D* meson and the muon serves to separate the charm and beauty contributions and the analysis provides comparable sensitivity to both. The total and differential experimental cross sections are compared to LO and NLO QCD calculations. The measured charm cross section is in good agreement with QCD predictions including higher order effects while the beauty cross section is higher.

[What is beauty? : Manifest for an aesthetic character medicine].

Science.gov (United States)

Harth, W

2017-12-01

Aesthetic medicine has in recent decades attained a growing social significance and firm place in the medical profession image. In a short time, a variety of technical procedures and processes have been developed and applied by specialized physicians. A further leading medical discussion regarding the central question "What is beauty" is missing compared with the technologically innovative progress. Beauty is characterized by an individual and subjective pleasure. Social media and fashion trends exert a central influence on common beauty ideals and aesthetic medicine. In practice, the artificial intervention must accord to the individual personality. Therefore, the professional term Aesthetic Medicine is insufficient and should be replaced by "Aesthetic Character Medicine". The particular purpose is the aim of graceful aging and a sustained adequate result which outlasts the zeitgeist. This requires medical know how and clear aesthetic self-conception of the physician. "Aesthetic Character Medicine" can be realized in a discourse, with the 10-step plan presented in this article.

Beauty particles would be identified in emulsion by their characteristic cascade decay through charm particles. This sort of signature would have a completely negligible background. The experiment would have the unique feature of being able to be sensitive to lifetimes as small as those expected for beauty, i.e. $10^{-14}$s < $\\tau$ < $10^{-13}$s. \\\\ Interesting events would be selected by the identification of three muons in the final state, coming from three of the four possible semi-leptonic decays of beauty of charmed particles. Muons would be identified in a hadron absorber equipped with three x-y plane hodoscopes, and 11 x-y-z planes of MWPC. \\\\Although the final sample of events to scan would be the 3 $\\mu$-events resulting from off-line analysis, it is intended to record data for all two-muon events. \\\\ A total of 67 stacks with approximate dimensions 15 x 10 x 5 cm$^{3}$ would be aligned with ...

Ethno beauty: practices of beautification among urban muslim middle-class women in Surabaya

Science.gov (United States)

Listyani, RH; Sadewo, FX S.; Legowo, M.

2018-01-01

This research examines practices of beautification by urban middle-class Muslim women using an ethnomethodology approach. Several theories are employed in this research including the theory of consumption (leisure class), sociology of body, middle-class theory and the concept of modern Islam. Results indicate that the beautiful concept according to Muslim middle-class urban women is white skin without stains, face without wrinkles, nose sharp, eyelashes and thick eyebrows and red lips. To be said to be beautiful, they took various efforts through beauty treatment, diet, fashion and dress up. In this study also revealed that their goal to self-care is pride and recognition in front of other fellow female friends and to happy partner (husband). This shows that the consumption through the body (fashions, diets, make up) and consumption around the body (beauty treatments) represent symbolic and material ways of positioning themselves within contemporary society - thus becoming ‘visible’. The implications of this research are this study is expected to contribute information and enrich the repertoire of social science especially sociology also for the development of research on body and beauty.

A twentieth-century triangle trade: selling black beauty at home and abroad, 1945–1965.

Science.gov (United States)

McAndrew, Malia

2010-01-01

This study examines the careers of African American beauty culturists as they worked in the United States, Europe, and Africa between 1945 and 1965. Facing push back at home, African American beauty entrepreneurs frequently sought out international venues that were hospitable and receptive to black Americans in the years following World War II. By strategically using European sites that white Americans regarded as the birthplace of Western fashion and beauty, African American entrepreneurs in the fields of modeling, fashion design, and hair care were able to win accolades and advance their careers. In gaining support abroad, particularly in Europe, these beauty culturists capitalized on their international success to establish, legitimize, and promote their business ventures in the United States. After importing a positive reputation for themselves from Europe to the United States, African American beauty entrepreneurs then exported an image of themselves as the world's premier authorities on black beauty to people of color around the globe as they sold their products and marketed their expertise on the African continent itself. This essay demonstrates the important role that these black female beauty culturists played, both as businesspeople and as race leaders, in their generation's struggle to gain greater respect and opportunity for African Americans both at home and abroad. In doing so it places African American beauty culturists within the framework of transatlantic trade networks, the Black Freedom Movement, Pan-Africanism, and America's Cold War struggle.

Nennu and Shunu: gender, body politics, and the beauty economy in China.

Science.gov (United States)

Yang, Jie

2011-01-01

This essay analyzes recent discourse on two emerging representations of women in China, "tender" women (nennu) and "ripe" women (shunu), in order to examine the relationships among gender, body politics, and consumerism. The discourse of nennu and shunu suggests that older, ripe women become younger and more tender by consuming fashions, cosmetic surgery technologies, and beauty and health care products and services because tender women represent the ideal active consumership that celebrates beauty, sexuality, and individuality. This discourse serves to enhance consumers' desire for beauty and health and to ensure the continued growth of China's beauty economy and consumer capitalism. Highlighting the role of the female body, feminine beauty, and feminine youth in developing consumerism, this discourse downplays the contributions of millions of beauty and health care providers (predominantly laid-off female workers and rural migrant women) and new forms of gender exploitation. Such an overemphasis on gender masks intensified class division. This essay suggests that women and their bodies become new terrains from which post-Mao China can draw its power and enact consumerism. Gender constitutes both an economic multiplier to boost China's consumer capitalism and a biopolitical strategy to regulate and remold women and their bodies into subjects that are identified with the state's political and economic objectives. Since consumerism has been incorporated into China's nation-building project, gender thus becomes a vital resource for both consumer capitalist development and nation building. This essay shows that both gender and the body are useful analytic categories for the study of postsocialism.

Does the world embody beautiful ideas? Pythagoras and Plato intuited that it should; Newton and Maxwell demonstrated how it could. But modern physics, and especially the quantum physics at its foundation, answers with a much more resounding and definitive 'Yes' I'll bring in history and art, as well as science, to make the case.(author)

What is beautiful is good because what is beautiful is desired: physical attractiveness stereotyping as projection of interpersonal goals.

Science.gov (United States)

Lemay, Edward P; Clark, Margaret S; Greenberg, Aaron

2010-03-01

The authors posit that the attribution of desirable interpersonal qualities to physically attractive targets is a projection of interpersonal goals; people desire to form and maintain close social bonds with attractive targets and then project these motivations onto those targets. Three studies support this model. Tendencies to see attractive novel targets depicted in photographs (Study 1), attractive romantic partners (Study 2), and attractive friends (Study 3) as especially interpersonally receptive and responsive were explained by perceivers' heightened desires to bond with attractive individuals. Additional findings regarding response latencies (Study 1) also supported this model. Many instances of the "beautiful is good" effect may not reflect stereotyping as it is typically construed. Rather, they may reflect projection of heightened desires to bond with beautiful people.

"Man-some": A Review of Male Facial Aging and Beauty.

Science.gov (United States)

Keaney, Terrence Colin

2017-06-01

Gender plays a significant role in determining facial anatomy and behavior, both of which are key factors in the aging process. Understanding the pattern of male facial aging is critical when planning aesthetic treatments on men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss. What also needs to be considered when planning a treatment is what makes men beautiful or "man-some". Male beauty strikes a balance between masculine and feminine facial features. A hypermasculine face can have negative associations. Men also exhibit different cosmetic concerns. Men tend to focus on three areas of the face - hairline, periocular area, and jawline. A comprehensive understanding of the male patient including anatomy, facial aging, cosmetic concerns, and beauty are needed for successful cosmetic outcomes.

Physical attractiveness biases in ratings of employment suitability: tracking down the "beauty is beastly" effect.

Science.gov (United States)

Johnson, Stefanie K; Podratz, Kenneth E; Dipboye, Robert L; Gibbons, Ellie

2010-01-01

The "what is beautiful is good" heuristic suggests that physically attractive persons benefit from their attractiveness in a large range of situations, including perceptions of employment suitability. Conversely, the "beauty is beastly" effect suggests that attractiveness can be detrimental to women in certain employment contexts, although these findings have been less consistent than those for the "what is beautiful is good" effect. The current research seeks to uncover situations in which beauty might be detrimental for female applicants. In two studies, we found that attractiveness can be detrimental for women applying for masculine sex-typed jobs for which physical appearance is perceived as unimportant.

Kalyanimath, Gurusiddeshwar J.; Sharanesh, T.; Ashwinikumar; Anita, M.

2012-01-01

Purpose: Beauty is not in the face; Beauty is a light in the heart. In our Ayurveda it is stated that Physical, Mental and Spiritual beauty as a combined unit projects the cosmetic sense of Ayurveda (Ch.Su 1/41). According to Ayurveda healthy skin is the result of overall condition of individuals and prescribes numerous skin care treatments that need to be pursued at every stage of life. Ayurveda determines beauty by Prakruti(body constitution), Sara (structural predominance), Samhanana (compactness of body), Twak (skin complexion), Pramana (measurement) and Dirghayu lakshana (symptom of long life). Ayurveda cosmetology started with garbhini paricharya, Dinacharya, Ratricharya and Ritucharya with practice of medicinal herbs and minerals. In day-to-day life, knowingly or unknowingly we exposing lots of chemicals /toxins to our body, those spoiling our natural beauty silently, this same concept is explained in Agada tantra under concept of Dhooshivisha (Su.Ka 2/33) and Garaviasha. Method: 1. Literature review of concept related to cosmetology in relation to Agada Tantra.2. Analysis and Interpretation of mode of action of Agada yoga's in relieving the symptoms of Twak vikaras. Result: 1. Specific Agada yogas like Bilwadi Agada , Dhooshivishari Agada, Moorvadi choorna, Paarantyadi Keram shows best preventive and curative action in twak vikaras.2. Some of the Agadas like Moorvadi choona (A.hrudaya) lepas have enhansess the internal and external beauty. Conclusion: Agada tantra is not only a branch of Ayurveda it deals with management of acute and chronic diseases but also a added benefit of being used for cosmetology.

Insufficient sleep increasingly characterizes modern society, contributing to a host of serious medical problems. Loss of sleep is associated with metabolic diseases such as obesity and diabetes, cardiovascular disorders, and neurological and cognitive impairments. Shifts in gut microbiome composition have also been associated with the same pathologies; therefore, we hypothesized that sleep restriction may perturb the gut microbiome to contribute to a disease state. In this study, we examined the fecal microbiome by using a cross-species approach in both rat and human studies of sleep restriction. We used DNA from hypervariable regions (V1-V2) of 16S bacteria rRNA to define operational taxonomic units (OTUs) of the microbiome. Although the OTU richness of the microbiome is decreased by sleep restriction in rats, major microbial populations are not altered. Only a single OTU, TM7-3a, was found to increase with sleep restriction of rats. In the human microbiome, we find no overt changes in the richness or composition induced by sleep restriction. Together, these results suggest that the microbiome is largely resistant to changes during sleep restriction.

Nievergelt Caroline M

2008-04-01

Full Text Available Abstract Background Delayed sleep phase disorder (DSPD is a condition in which patients have difficulty falling asleep before the early morning hours and commonly have trouble awakening before late morning or even early afternoon. Several studies have suggested that variations in habitual bedtime are 40–50% heritable. Methods We recruited a case series of 205 participants, along with 221 controls (DSPD-C with normal sleep, roughly matched for age, gender, and ancestry. A representative sample of San Diego adults recruited some years before was already available to confirm the control group. Both DSPD and DSPD-C provided blood or saliva samples for DNA and completed extensive questionnaires about sleep habits, sleep history, family history, sleep quality, morningness-eveningness traits, depression, mania, and seasonality of symptoms. The DSPD group wore wrist actigraphs for a median of 13.2 days. The representative sample collected previously had undergone actigraphic recordings, from which 48 hours of data were generally available. Results The DSPD and DSPD-C samples showed almost no overlap on morningness-eveningness scores. DSPD cases went to bed and arose about 3 hours later than the DSPD-C and the representative sample. DSPD cases reported more difficulties with sleep, poorer sleep quality, and more depression, but there was no significant difference in a history of mania. DSPD cases reported more family history of late bedtimes, but female DSPD reported that their fathers' bedtimes were later than the fathers of male DSPD. Conclusion These results indicate a DSPD phenotype is familial and associated with unipolar depression.

Male Beauty in the Eye of the Beholder? Guys, Guises and Disguise in Patrick White’s The Twyborn Affair

Directory of Open Access Journals (Sweden)

Jean-Francois Vernay

2012-05-01

Full Text Available Peer reviewed article. “Beauty is in the eye of the beholder”, which first appeared in the 3rd century BC in Greek, quickly gained proverbial currency in the English language thanks to its wisdom. Admittedly, whenever beauty has been acknowledged, one should take it primarily as a comment on the beholder rather than on the model. In heterosexual relationships, male beauty would thus be informative of the female gaze and conception of aesthetics. But what of homosexual relationships? Logically, male beauty would inform as much on the aesthetics of the beholder as on the canons of male beauty through the representation of the perfect man. Now what if the male model appeals to both male and female beholders? Can gay men and straight women share the same aesthetics of the male body? Do they seek and value the same things in a partner? And then what if the male model switches to female beauty all the while sustaining an unflinching power of seduction? Would that prove that beauty is genderless or would that mean that desirability is unrelated to beauty? On a creative level, when White depicts an ambiguous protean protagonist, beauty essentially relies on his characterization skills. But is male beauty objectively inherent to the model or is it solely to be found in the novelist’s subjective representation of his central character?

Training of beauty salon professionals in disease prevention using interactive tele-education.

Infectious diseases can be acquired in places where invasive procedures are often performed without the proper care of hand washing and material sterilization. There are approximately 500,000 beauty and esthetics centers in Brazil, which are visited by thousands of people every day. Many diseases, including sexually transmitted infections, are still highly prevalent in Brazil, such as warts caused by human papillomavirus, hepatitis B and C, and human immunodeficiency virus infection, and can be transmitted in beauty salons. We have developed a tele-education course divided into four main themes: sexually transmitted infections, indoor health in beauty salon workplaces, hand washing, and material sterilization. The course was made available through a Web site, which included a face-to-face meeting, Web synchronous meetings (chats and Web conferences), and asynchronous resources (reading material, discussion lists, situations simulator, educational videos, and three-dimensional virtual human video animation on sexually transmitted infections and hand washing), mediated by professors and coordinators. Fifty-two beauty professionals and 33 other professionals were enrolled from different regions. Of the 61 who completed the course and received a certificate at the course's end, 100% considered good to excellent the course's applicability to everyday life and would recommend it to a fellow professional. The results demonstrate the feasibility of an interactive, tele-education model using low-cost tools as an educational resource to teach beauty professionals. In the future, this may become a branch of nationwide telehealth action.

The increased demand for facial cosmetic surgery has come from a more diverse, informed, and selective patient population from all walks of life. Virtually no two patients have the same background or cosmetic objectives. However, the classic tenets of beauty including phi, symmetry, averageness, youthfulness, and sexual dimorphism can be applied to persons of all ethnicities to assist in objectifying the abstract concept.

"You are so beautiful"*: behind women's attractiveness towards the biology of reproduction: a narrative review.

2012-10-01

Female beauty has always attracted human beings. In particular, beauty has been interpreted in terms of reproductive potential and advantage in selection of mates. We have reviewed the recent literature on female facial and physical beauty with the objective of defining which parameters could influence female attractiveness. Symmetry, averageness, and sexual dimorphism with regards to facial beauty, as well as waist-to-hip ratio (WHR), breast size, and body mass index (BMI) for physical beauty, have been assessed. In current societies, it appears that facial attractiveness results from a mixture of symmetry and averageness of traits, high forehead and cheekbones, small nose and chin, full lips, thin eyebrows, and thick hair. A low WHR reliably characterized physical attractiveness, whereas inconsistencies have been observed in the evaluation of breast size and BMI. The importance of breast size appears to vary with time and sex of evaluators, whereas the impact of BMI is related to socio-economic conditions. The various hypotheses behind beauty and the role of attractiveness in mate choice and sexual selection are here described in terms of continuation of human species. Intriguing associations are emerging between features of attractiveness and some reproductive disorders, as both are substantially influenced by sex steroid hormones.

[Beauty judgment: review of the literature].

Faure, Jacques; Bolender, Yves

Esthetic judgments are surely subjective, but as surely, that does not preclude them being studied objectively through rigorous scientific methods. The factual basis of a science of esthetics is not to settle whether some person or image is "objectively beautiful" but rather to determine whether some representative set or sets of individuals judge or experience him/her/it as beautiful or unattractive. The aim of this paper is to review the definitional, theoretical and methodological aspects pertaining to the perception of facial/dental attractiveness by a group of representative individuals. The first part lays down the basic principles of the perception of facial/dental attractiveness: the perception involves a jury, a field of investigation and a test providing quantitative data; the following general determinants of beauty perception are reviewed: the average morphology, the judge's cultural background, the numerology, the judge's ethnical origin. Indirect determinants are the dentition, the osseous architecture and the muscular envelope. Some disruptive factors might alter the judges' facial perception. They might be qualified as either peripheral to the face or psycho-social factors. Peripheral factors include hair style and color, skin hue, wrinkles, lips color... Psycho-social factors cover the personality of the subject being evaluated, his/her intelligence or behavior. The second part deals specifically with the methodology used to determine facial attractiveness and to correlate this latter with a specific morphology. Typically such a study aims to determine average esthetic preferences for some set of visual displays among a particular jury, given a specific task to judge esthetic quality or qualities. The sample being studied, the displays, the jury or jurys, the rating procedure must all be specified prior to collecting data. A specific emphasis will be given to the rating process and the associated morphometrics, the ultimate goal being to

Full Text Available Background This article aims to investigate current perceptions of beauty of the general public and physicians without a specialization in plastic surgery performing aesthetic procedures. Methods A cross-sectional and interviewing questionnaire was administered to 290 people in Seoul, South Korea in September 2015. The questionnaire addressed three issues: general attitudes about plastic surgery (Q1, perception of and preferences regarding Korean female celebrities’ facial attractiveness (Q2, and the relative influence of each facial aesthetic subunit on overall facial attractiveness. The survey’s results were gathered by a professional research agency and classified according to a respondent’s gender, age, and job type (95%±5.75% confidence interval. Statistical analysis was performed using SPSS ver. 10.1, calculating one-way analysis of variance with post hoc analysis and Tukey’s t-test. Results Among the respondents, 38.3% were in favor of aesthetic plastic surgery. The most common source of plastic surgery information was the internet (50.0%. The most powerful factor influencing hospital or clinic selection was the postoperative surgical results of acquaintances (74.9%. We created a composite face of an attractive Korean female, representing the current facial configuration considered appealing to the Koreans. Beauty perceptions differed to some degree based on gender and generational differences. We found that there were certain differences in beauty perceptions between general physicians who perform aesthetic procedures and the general public. Conclusions Our study results provide aesthetic plastic surgeons with detailed information about contemporary Korean people’s attitudes toward and perceptions of plastic surgery and the specific characteristics of female Korean faces currently considered attractive, plus trends in these perceptions, which should inform plastic surgeons within their specialized fields.

Graham Farmelo, author and former particle physicist, visited CERN on 25 March. To the CERNois gathered in the Main Auditorium, he talked about his new book The Strangest Man, a biography of Paul Dirac. Dirac was obsessed by the importance of mathematical beauty in fundamental physics, a belief that was “almost a religion” to him. Farmelo himself has no doubts: among all of the natural phenomena the LHC may unveil, supersymmetry is the most beautiful.   Talking about the life of a physicist to draw the attention of the public to the science: that was the idea behind Graham Farmelo decision to write a biography of Paul Dirac. The book won the 2009 Costa Biography Award. “I chose Paul Dirac because he was the first truly modern theoretical physicist but he is virtually unknown to the public”, explains Graham Farmelo. “Dirac had a fascinating life. He was not born in a wealthy or a particularly brilliant family but he ended up conceiving in his head ...

A study of the production of beauty baryons in Z 0 decays is reported. The analysis is based on 1 Million Z 0 hadronic events collected by the DELPHI detector in the 1990-92 data taking. Beauty baryon signals are obtained with three complementary methods: search of Λ (Λ-bar) correlated to a high p T l - (l + ) in the same jet; the presence of a secondary vertex formed by a fast proton (p>5 GeV/c) and a lepton of opposite sign; the presence of Λ c baryon associated with a high p T lepton in the same jet. From these signals, the average lifetime of beauty baryons and inclusive branching fractions have been measured. (author). 5 refs., 4 figs

Full Text Available This article examines how flexible work economy has been affecting a group of beauty salons’ workers in Santiago, Chile. They do not have a work contract and receive their payment as if they were giving an independent service, but depend on the rules their bosses impose them. The kind of work described in the article appears to be a new arrangement within the context of urban informality, which has present and future implications regarding social security and uncertainty. Drawing on ethnographic observation in four beauty salons, I describe how the embodied belief of being an independent worker helps to enact many skills required by the flexible work economy.

Measurement of open beauty production at HERA in the D*μ final state

2006-09-01

The production of beauty quarks with a D *± and a muon in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb -1 . Low transverse-momentum thresholds for the muon and D * meson allow a measurement of beauty production closer to the production threshold than previous measurements. The beauty signal was extracted using the charge correlations and angular distributions of the muon with respect to the D * meson. Cross sections for photoproduction and deep inelastic scattering are somewhat higher than, but compatible with, next-to-leading-order QCD predictions, and compatible with other measurements. (orig.)

Genetic Dissociation of Daily Sleep and Sleep Following Thermogenetic Sleep Deprivation in Drosophila.

Sleep rebound-the increase in sleep that follows sleep deprivation-is a hallmark of homeostatic sleep regulation that is conserved across the animal kingdom. However, both the mechanisms that underlie sleep rebound and its relationship to habitual daily sleep remain unclear. To address this, we developed an efficient thermogenetic method of inducing sleep deprivation in Drosophila that produces a substantial rebound, and applied the newly developed method to assess sleep rebound in a screen of 1,741 mutated lines. We used data generated by this screen to identify lines with reduced sleep rebound following thermogenetic sleep deprivation, and to probe the relationship between habitual sleep amount and sleep following thermogenetic sleep deprivation in Drosophila. To develop a thermogenetic method of sleep deprivation suitable for screening, we thermogenetically stimulated different populations of wake-promoting neurons labeled by Gal4 drivers. Sleep rebound following thermogenetically-induced wakefulness varies across the different sets of wake-promoting neurons that were stimulated, from very little to quite substantial. Thermogenetic activation of neurons marked by the c584-Gal4 driver produces both strong sleep loss and a substantial rebound that is more consistent within genotypes than rebound following mechanical or caffeine-induced sleep deprivation. We therefore used this driver to induce sleep deprivation in a screen of 1,741 mutagenized lines generated by the Drosophila Gene Disruption Project. Flies were subjected to 9 h of sleep deprivation during the dark period and released from sleep deprivation 3 h before lights-on. Recovery was measured over the 15 h following sleep deprivation. Following identification of lines with reduced sleep rebound, we characterized baseline sleep and sleep depth before and after sleep deprivation for these hits. We identified two lines that consistently exhibit a blunted increase in the duration and depth of sleep after

Prolonged Expression of Secreted Enzymes in Dogs After Liver-Directed Delivery of Sleeping Beauty Transposons: Implications for Non-Viral Gene Therapy of Systemic Disease.

The non-viral, integrating Sleeping Beauty (SB) transposon system is efficient in treating systemic monogenic disease in mice, including hemophilia A and B caused by deficiency of blood clotting factors and mucopolysaccharidosis types I and VII caused by α-L-iduronidase (IDUA) and β-glucuronidase (GUSB) deficiency, respectively. Modified approaches of the hydrodynamics-based procedure to deliver transposons to the liver in dogs were recently reported. Using the transgenic canine reporter secreted alkaline phosphatase (cSEAP), transgenic protein in the plasma was demonstrated for up to 6 weeks post infusion. This study reports that immunosuppression of dogs with gadolinium chloride (GdCl 3 ) prolonged the presence of cSEAP in the circulation up to 5.5 months after a single vector infusion. Transgene expression declined gradually but appeared to stabilize after about 2 months at approximately fourfold baseline level. Durability of transgenic protein expression in the plasma was inversely associated with transient increase of liver enzymes alanine transaminase and aspartate transaminase in response to the plasmid delivery procedure, which suggests a deleterious effect of hepatocellular toxicity on transgene expression. GdCl 3 treatment was ineffective for repeat vector infusions. In parallel studies, dogs were infused with potentially therapeutic transposons. Activities of transgenic IDUA and GUSB in plasma peaked at 50-350% of wildtype, but in the absence of immunosuppression lasted only a few days. Transposition was detectable by excision assay only when the most efficient transposase, SB100X, was used. Dogs infused with transposons encoding canine clotting factor IX (cFIX) were treated with GdCl 3 and showed expression profiles similar to those in cSEAP-infused dogs, with expression peaking at 40% wt (2 μg/mL). It is concluded that GdCl 3 can support extended transgene expression after hydrodynamic introduction of SB transposons in dogs, but that alternative

Full Text Available Nonmainstream body modification practitioners actively demonstrate a confounding agency that often results in the stigmatization of their physical characteristics, their moral constitution, and their behavior. By inscribing meaning and identity in visible ways rather than allowing society to project expectations onto them based on their gender, age, race, sexual orientation, and so on, nonmainstream body modifiers present a unique challenge to American conceptions of what is healthy, what is beautiful, and what is human. Using Patricia Hill Collins’ idea of controlling images, Erving Goffman’s conceptions of stigma, and Arthur W. Frank’s styles of body usage typology, this article examines constructions of deviance within the embodied framework of unconventional body modification practices.

Beauty and healing: examining sociocultural expectations of the embodied goddess.

Studies indicate mental health improvement can occur via religious communities offering social support and other resources. Many people from many cultures regard medicine as a supernatural or magical treatment that can somehow lead to a better state of living. In medical advertising, female role portrayal involves the blending of beauty, ritual and attractiveness in combination with the best product image. A Chinese saying suggests that, "A girl will doll herself up for him who loves her." Female role attraction is a very important ethical subject in gender issues. Moving forward in time, female role visualization and consumption in medical advertising reveal depictions that encouraged women to do some self-searching and find, or develop, inner strength. This study is designed to examine female role portrayals in a restricted patriarchal society. The results indicate that the ideology of motherhood is an accepted social orientation that the public readily identifies with. Results further indicate that beautification through medical products incorporates an emotional element of religious healing and that the objectification of beauty in the media reveals a possible neglect of women's internal beauty.

Symmetry, beauty and belief in high-energy physics

2017-11-01

Full Text Available This paper engages with the aesthetics of knowl-edge, both in its sense as the connection between knowledge and ‘aesthetic’ judgements of beauty, or ugliness, and of the many ‘aesthetic’ – that is to say sensually perceivable – dimensions of knowledge, which are always to be seen to be constituting an epistemic factor in its production and consumption. On the one hand I analyse how in recent decades the connection between beauty and truth has been systematically employed to both inspire and guide research in high-energy physics; at the same time I also show how this use of aesthetic judgement only reveals its constitutive role in physics research when paying attention to the broad range of aesthetic strategies employed for expressing scientific knowledge.

Obstructive sleep apnoea/hypopnea syndrome (OSA) is characterized by obstruction of the upper airway during sleep, resulting in repetitive breathing pauses accompanied by oxygen desaturation and arousal from sleep. Among the candidate genes affecting the risk of OSA, genes whose polymorphisms influence the development of diseases with similar pathogenesis such as OSA could be listed: APOE, genes for leptin and leptin receptor, TNFA1, ADRB2 and ACE (gene for angiotensin-converting enzyme). Until now there has been a confirmed relationship between ACE gene polymorphism and cardiovascular diseases, but its effect on the incidence of OSA is debatable. The aim of this study was to investigate the effect of ACE gene insertion/deletion (I/D) polymorphism on the risk of OSA. Fifty-five patients with confirmed diagnose of OSA and qualified to CPAP therapy entered the study. The control group included 50 subjects who did not complain of any sleep related symptoms. Diagnose of OSA was set on the basis of full overnight polysomnography together with Epworth Sleepiness Scale according to American Academy of Sleep Medicine guidelines. DNA was isolated from peripheral blood leukocytes with Qiagen DNA mini Kit. ACE gene polymorphism was determined in genomic DNA using allele specific polymerase chain reaction. Different sizes of PCR products were observed on agarose gel electrophoresis. There were non-significant differences in the frequency of ACE genotypes. However, allele D had significantly lower prevalence in the study group than in the control group. (χ(2) = 4.25 p = 0.04). Moreover, I allele carriers had a threefold greater risk of developing OSA (HR = 2.748, 95% CI = 1.029-7.340, p gene polymorphism might be useful to determine the risk of developing OSA in clinically predisposed patients.

Sleep is critical for normal brain function and mental health. However, the molecular mechanisms mediating the impact of sleep loss on both cognition and the sleep electroencephalogram remain mostly unknown. Acute sleep loss impacts brain gene expression broadly. These data contributed to current hypotheses regarding the role for sleep in metabolism, synaptic plasticity and neuroprotection. These changes in gene expression likely underlie increased sleep intensity following sleep deprivation ...

Measurement of beauty photoproduction using decays into muons in dijet events at HERA

International Nuclear Information System (INIS)

2009-01-01

Beauty photoproduction in dijet events has been measured at HERA with the ZEUS detector using an integrated luminosity of 126 pb -1 . Beauty was identified in events with a muon in the final state by using the transverse momentum of the muon relative to the closest jet. Lifetime information from the silicon vertex detector was also used; the impact parameter of the muon with respect to the primary vertex was exploited to discriminate between signal and background. Cross sections for beauty production as a function of the muon and the jet variables as well as dijet correlations are compared to QCD predictions and to previous measurements. The data are well described by predictions from next-to-leading-order QCD.

Cognitive control and unusual decisions about beauty: An fMRI study

2014-07-01

Full Text Available Studies of visual aesthetic preference have shown that people without art training generally prefer representational paintings to abstract paintings. This, however, is not always the case: preferences can sometimes go against this usual tendency. We aimed to explore this issue, investigating the relationship between ‘unusual responses’ and reaction time in an aesthetic appreciation task. Results of a behavioural experiment confirmed the trend for laypeople to consider as beautiful mostly representational stimuli and as not beautiful mostly abstract ones (‘usual response’. Furthermore, when participants gave unusual responses, they needed longer time, especially when considering abstract stimuli as beautiful. We interpreted this longer time as greater involvement of the cognitive mastering and evaluation stages during the unusual responses. Results of an fMRI experiment indicated that the anterior cingulate, orbitofrontal cortex and insula were the main structures involved in this effect. We discuss the possible role of these areas in an aesthetic appreciation task.

Stable gene transfer of CCR5 and CXCR4 siRNAs by sleeping beauty transposon system to confer HIV-1 resistance

Directory of Open Access Journals (Sweden)

2008-07-01

Full Text Available Abstract Background Thus far gene therapy strategies for HIV/AIDS have used either conventional retroviral vectors or lentiviral vectors for gene transfer. Although highly efficient, their use poses a certain degree of risk in terms of viral mediated oncogenesis. Sleeping Beauty (SB transposon system offers a non-viral method of gene transfer to avoid this possible risk. With respect to conferring HIV resistance, stable knock down of HIV-1 coreceptors CCR5 and CXCR4 by the use of lentiviral vector delivered siRNAs has proved to be a promising strategy to protect cells from HIV-1 infection. In the current studies our aim is to evaluate the utility of SB system for stable gene transfer of CCR5 and CXCR4 siRNA genes to derive HIV resistant cells as a first step towards using this system for gene therapy. Results Two well characterized siRNAs against the HIV-1 coreceptors CCR5 and CXCR4 were chosen based on their previous efficacy for the SB transposon gene delivery. The siRNA transgenes were incorporated individually into a modified SB transfer plasmid containing a FACS sortable red fluorescence protein (RFP reporter and a drug selectable neomycin resistance gene. Gene transfer was achieved by co-delivery with a construct expressing a hyperactive transposase (HSB5 into the GHOST-R3/X4/R5 cell line, which expresses the major HIV receptor CD4 and and the co-receptors CCR5 and CXCR4. SB constructs expressing CCR5 or CXCR4 siRNAs were also transfected into MAGI-CCR5 or MAGI-CXCR4 cell lines, respectively. Near complete downregulation of CCR5 and CXCR4 surface expression was observed in transfected cells. During viral challenge with X4-tropic (NL4.3 or R5-tropic (BaL HIV-1 strains, the respective transposed cells showed marked viral resistance. Conclusion SB transposon system can be used to deliver siRNA genes for stable gene transfer. The siRNA genes against HIV-1 coreceptors CCR5 and CXCR4 are able to downregulate the respective cell surface proteins

The interaction between sleep deprivation and epilepsy has been well described in electrophysiological studies, but the mechanisms underlying this association remain unclear. The present study evaluated the effects of sleep deprivation on locomotor activity and genetic damage in the brains of rats treated with saline or pilocarpine-induced status epilepticus (SE). After 50 days of pilocarpine or saline treatment, both groups were assigned randomly to total sleep deprivation (TSD) for 6 h, paradoxical sleep deprivation (PSD) for 24 h, or be kept in their home cages. Locomotor activity was assessed with the open field test followed by resection of brain for quantification of genetic damage by the single cell gel electrophoresis (comet) assay. Status epilepticus induced significant hyperactivity in the open field test and caused genetic damage in the brain. Sleep deprivation procedures (TSD and PSD) did not affect locomotor activity in epileptic or healthy rats, but resulted in significant DNA damage in brain cells. Although PSD had this effect in both vehicle and epileptic groups, TSD caused DNA damage only in epileptic rats. In conclusion, our results revealed that, despite a lack of behavioral effects of sleep deprivation, TSD and PSD induced genetic damage in rats submitted to pilocarpine-induced SE.

The neural correlates of beauty comparison.

Kedia, Gayannée; Mussweiler, Thomas; Mullins, Paul; Linden, David E J

2014-05-01

Beauty is in the eye of the beholder. How attractive someone is perceived to be depends on the individual or cultural standards to which this person is compared. But although comparisons play a central role in the way people judge the appearance of others, the brain processes underlying attractiveness comparisons remain unknown. In the present experiment, we tested the hypothesis that attractiveness comparisons rely on the same cognitive and neural mechanisms as comparisons of simple nonsocial magnitudes such as size. We recorded brain activity with functional magnetic resonance imaging (fMRI) while participants compared the beauty or height of two women or two dogs. Our data support the hypothesis of a common process underlying these different types of comparisons. First, we demonstrate that the distance effect characteristic of nonsocial comparisons also holds for attractiveness comparisons. Behavioral results indicated, for all our comparisons, longer response times for near than far distances. Second, the neural correlates of these distance effects overlapped in a frontoparietal network known for its involvement in processing simple nonsocial quantities. These results provide evidence for overlapping processes in the comparison of physical attractiveness and nonsocial magnitudes.

Short Sleep as an Environmental Exposure: A Preliminary Study Associating 5-HTTLPR Genotype to Self-Reported Sleep Duration and Depressed Mood in First-Year University Students

Objectives: This study examined whether the 5-HTTLPR polymorphism in the SLC6A4 gene is associated with self-reported symptoms of depressed mood in first-year university students with a persistent pattern of short sleep. Design: Students provided DNA samples and completed on-line sleep diaries and a mood scale during the first semester. A priori phenotypes for nocturnal sleep and mood scores were compared for the distribution of genotypes. Setting: Brown University, Providence, Rhode Island. Participants: A sample of 135 first-year students, 54 male, 71 Caucasian, mean age 18.1 (± 0.5) yr. Interventions: None. Measurements: Students completed on-line sleep diaries daily across the first term (21-64 days; mean = 51 days ± 11) and Center for Epidemiologic Studies-Depression (CES-D) mood scale after 8 wk. DNA was genotyped for the triallelic 5-HTTLPR polymorphism. Low-expressing S and LGpolymorphisms were designated S′, and high-expressing LA was designated L′. Phenotype groups were identified from a combination of CES-D (median split: high > 12; low sleep time (TST) from diaries: (shorter ≤ 7 hr; longer ≥ 7.5 hr). Three genotypes were identified (S′S′, S′L′, L′L′); the S′S′ genotype was present in a higher proportion of Asian than non-Asian students. Results: Four phenotype groups were compared: 40 students with shorter TST/high CES-D; 34 with shorter TST/low CES-D; 29 with longer TST/high CES-D; 32 with longer TST/low CES-D. Female:male distribution did not vary across phenotype groups (chi-square = 1.39; df = 3; P = 0.71). S′S′ participants (n = 23) were overrepresented in the shorter TST/high CES-D group (chi- square = 15.04; df = 6; P sleep and higher depressed mood are more likely than others to carry a variant of the SLC6A4 gene associated with low expression of the serotonin transporter.

2013-05-01

Ultraviolet radiation exposure through natural sunlight or tanning lamps is a risk factor for skin cancer. As the media can influence behavior, we studied whether watching reality television (TV) beauty shows is associated with tanning lamp use or outdoor tanning. College students (n = 576) were surveyed on their reality TV beauty show watching, their use of tanning lamps, and outdoor tanning behavior. We asked media attitude questions about connectivity with reality TV shows and Internet use of Facebook to discuss reality TV shows. Those who did versus did not watch reality TV beauty shows used tanning lamps (12.9% vs 3.7%, P < .001) and tanned outdoors (43.3% vs 28.7%, P < .001) at significantly greater percentages. Significant predictors of tanning lamp use included watching reality TV beauty shows (odds ratio [OR] 2.58, 95% confidence interval [CI] 1.11-6.00), increasing age (OR 1.17, 95% CI 1.04-1.32), and female sex (OR 10.16, 95% CI 3.29-31.41). Significant predictors of outdoor tanning included watching reality TV beauty shows (OR 2.11, 95% CI 1.33-3.34). The specific names of the reality TV beauty shows watched were not obtained and therefore we cannot determine if particular shows were more or less associated with this behavior. Watching reality TV beauty shows is associated with both tanning lamp use and outdoor tanning. Dermatologists should consider discussing the potential harmful aspects of tanning beds and outdoor tanning, especially with their patients who watch reality TV beauty shows.

2012-01-01

The meson-baryon coupled channel unitary approach with the local hidden gauge formalism is extended to the hidden beauty sector. A few narrow N ⁎ and Λ ⁎ resonances around 11 GeV are predicted as dynamically generated states from the interactions of heavy beauty mesons and baryons. Production cross sections of these predicted resonances in pp and ep collisions are estimated as a guide for the possible experimental search at relevant facilities.

A recent study on trace elements in beauty products and cosmetics sold on the Asian market has shown the presence of high levels of U, Th and rare earth elements in so called 'Hormesis cosmetics'. For the purpose of comparison, some more information about trace elements in European cosmetics would be useful. In this paper the results obtained using k 0 -standardised Instrumental Neutron Activation Analysis (k 0 -INAA) for more than 20 trace elements in 20 different beauty products collected from the European market are presented. We found traces of Ba, As and Sb which is in breach with European legislation. For some of the other elements like Cr and Co further speciation is needed in order to evaluate their presence in beauty products. (author)

The production of beauty quarks with a D{sup *{+-}} and a muon in the final state has been measured with the ZEUS detector at HERA using an integrated luminosity of 114 pb{sup -1}. Low transverse-momentum thresholds for the muon and D{sup *} meson allow a measurement of beauty production closer to the production threshold than previous measurements. The beauty signal was extracted using the charge correlations and angular distributions of the muon with respect to the D{sup *} meson. Cross sections for photoproduction and deep inelastic scattering are somewhat higher than, but compatible with, next-to-leading-order QCD predictions, and compatible with other measurements. (orig.)

Longing for Clouds - Does Beautiful Weather have to be Fine?

Directory of Open Access Journals (Sweden)

Mădălina Diaconu

2016-01-01

Full Text Available Any attempt to outline a meteorological aesthetics centered on so-called beautiful weather has to overcome several difficulties: In everyday life, the appreciation of the weather is mostly related to practical interests or reduced to the ideal of stereotypical fine weather that is conceived according to blue-sky thinking irrespective of climate diversity. Also, an aesthetics of fine weather seems, strictly speaking, to be impossible given that such weather conditions usually allow humans to focus on aspects other than weather, which contradicts the autotelic character of beauty. The unreflective equation of beautiful weather with moderately sunny weather and a cloudless sky also collides with the psychological need for variation: even living in a “paradisal” climate would be condemned to end in monotony. Finally, whereas fine weather is related in modern realistic literature to cosmic harmony and a universal natural order, contemporary literary examples show that in the age of the climate change, fine weather may be deceitful and its passive contemplation, irresponsible. This implies the necessity of a reflective aesthetic attitude on weather, as influenced by art, literature, and science, which discovers the poetics of bad weather and the wonder that underlies average weather conditions.

Sleep Applications to Assess Sleep Quality.

This article highlights the potential uses that smartphone applications may have for helping those with sleep problems. Applications in smartphones offer the promised possibility of detection of sleep. From the author's own experience, one can also conclude that sleep applications are approximately as good as polysomnography in detection of sleep time, similar to the conventional wearable actimeters. In the future, sleep applications will help to further enhance awareness of sleep health and to distinguish those who actually poorly and only briefly sleep from those who suffer more likely from paradox insomnia.

1999-01-01

Using a sample of 10 8 triggered events, produced in π-Cu interactions at 350 GeV/c, we have identified 26 beauty events. The estimated background in this sample is 0.6 ± 0.6 events. From these data, assuming a linear A-dependence, we measure a beauty production cross-section integrated over all x F of 5.7 +1.3 -1.1 (stat.) +0.6 -0.5 (syst.) nb/N. Differential distributions with respect to x F and p 2 T have been determined as well as some two-particle kinematic variables. Our results are compared with previous experiments and with a next-to-leading-order QCD calculation

Humour, beauty, and culture as personal health resources: experiences of elderly Swedish women.

Science.gov (United States)

Forssén, Annika S K

2007-01-01

This paper explores how a group of elderly women used humour, beauty, and cultural activities to maintain physical and mental well-being. The paper reports on one aspect of a qualitative study on women's work and health in a lifetime perspective. Interviews with 20 strategically selected Swedish women, aged 63 to 83 years, were audiotaped and analysed according to a phenomenological approach. During the interview process, the researchers became increasingly aware that the women had clear ideas about what enabled them to feel well and healthy - even when actually quite diseased. Creating and enjoying humour, beauty, and culture formed part of such strategies. Joking with workmates made hard, low-status jobs easier, helped them endure pain, and helped balance marital difficulties. Creating a nice and comfortable home gave pleasure and a little luxury in a life filled with necessities. Making articles for everyday use more beautiful was regarded as worthwhile, because it gave delight to them and their families. Gains from cultural activities were social, aesthetic, and existential - the latter through a feeling of self-recognition and being heard. Humour, beauty, and culture formed a greater part of these women's survival strategies than expected. Making everyday life more aesthetic is an undervalued aspect of women's health-creating work in the family. Through their lifelong experience as carers and homemakers, elderly women possess special knowledge regarding what may promote health, a knowledge that should be tapped. When supplying elderly women with social care, their needs for humour, beauty, and culture should be respected.

This study investigated whether believing beauty is a primary currency for women operates as an antecedent force in the relation between self-objectification and gender activism. Ninety-four ethnically diverse women attending a small liberal arts college in the southeastern United States completed the study questionnaires online for course credit. Preliminary results demonstrated beauty as currency belief, self-objectification, and support for the gender status quo were negatively associated with gender activism. A serial mediation analysis revealed support for the proposed model: Beauty as currency belief was indirectly and inversely linked to gender activism through self-objectification and support for the gender status quo, offering initial evidence for our beauty as currency hypothesis. These findings suggest belief in the notion women will reap more benefits from their bodies than other attributes or pursuits may be an important legitimizing feature of feminine beauty ideology that works through self-objectification against gender social change.

Despite the high prevalence of hypoactive sexual desire disorder (HSDD), especially among women, this sexual disorder remains poorly understood. Among the multiple factors possibly involved in HSDD, particularities in the cognitive evaluations of social stimuli need to be better characterized. Especially, beauty and attractiveness judgments, two dimensions of interpersonal perception that are related but differ on their underlying motivational aspects, may vary according to the level of sexual desire. The main goal of this study was to investigate whether women with and without HSDD differ in their evaluations of beauty and attractiveness of men's faces and voices. Young women from the general population (controls, n = 16) and with HSDD (patients, n = 16) took part in the study. They were presented with a series of neutral/nonerotic voices and faces of young men from the GEneva Faces And Voices database. Ratings of beauty (i.e., assessments of aesthetic pleasure) and of attractiveness (i.e., assessments of the personal propensity to feel attracted to someone) and the frequency to which the participants pressed a key to see or listen to each stimulus again were the main outcome measures. Ratings of attractiveness were lower than ratings of beauty in both groups of women. The dissociation between beauty and attractiveness was larger in women with HSDD than in control participants. Patients gave lower attractiveness ratings than the controls and replayed the stimuli significantly less often. These results suggest that women with HSDD are characterized by specific alterations of the motivational component of men's perception, very early in the process of interpersonal relationships. Our findings have significant implications, both in better understanding the specific cognitive processes underlying hypoactive sexual desire and more largely the evaluative processes involved in human mate choice. © 2014 International Society for Sexual Medicine.

Cancer patients are offered more and more access to beauty care during their stay in the hospital. This kind of intervention has not been evaluated yet. Primary objective of our research was to determine what type of evaluation strategy to be implemented (as a supportive care with quality of life and/or medical benefits; as a service providing immediate comfort); intermediate objective was to investigate in scientific terms (psychological, sociological) the experience of beauty care by patients. Sixty patients (all users of beauty care provided by hospital, 58 female, most of them treated for breast cancer, two male, mean age 53 years) and 11 nurses and physicians, from four French cancer centres were included. We used direct observation and semi-structured interviews, conducted by a sociologist and a psychologist; different types of beauty care were concerned. All the interviewed patients were satisfied. Patients appreciated acquiring savoir-faire on how to use make-up and on personal image enhancement. Psychological and social well-being benefits were mentioned. The beauty care was not alleged to be reducing the side effects of the treatments, but it had helped patients to accept or bear the burden of them. Providing care beyond that which is directly curative was appreciated by the patients as a sign that they were treated as a "whole" person. The survey brings valuable clues concerning beauty care experience by cancer patients; it suggests the relevance of quantitative evaluation of the immediate and long-term effects on the quality of life.

Measurement of charm and beauty dijet cross sections in photoproduction at HERA using the H1 vertex detector

A measurement of charm and beauty dijet photoproduction cross sections at the ep collider HERA is presented. The lifetime signature of c- and b-flavoured hadrons is exploited to determine the fractions of events in the sample containing charm or beauty. Differential dijet cross sections for charm and beauty, and their relative contributions to the flavour inclusive dijet photoproduction cross section, are measured. Taking into account the theoretical uncertainties, the charm cross sections are consistent with a QCD calculation in next-to-leading order, the predicted cross sections for beauty production being somewhat lower than the measurement.

Beauty as Fit: A Metaphor in Mathematics?

Raman, Manya; Öhman, Lars-Daniel

2013-01-01

Beauty, which plays a central role in the practice of mathematics (Sinclair 2002), is almost absent in discussions of school mathematics (Dreyfus and Eisenberg 1986). This is problematic, because students will decide whether or not to continue their studies in mathematics without having an accurate picture of what the subject is about. In order to…

Combining universal beauty and cultural context in a unifying model of visual aesthetic experience.

Science.gov (United States)

Redies, Christoph

2015-01-01

In this work, I propose a model of visual aesthetic experience that combines formalist and contextual aspects of aesthetics. The model distinguishes between two modes of processing. First, perceptual processing is based on the intrinsic form of an artwork, which may or may not be beautiful. If it is beautiful, a beauty-responsive mechanism is activated in the brain. This bottom-up mechanism is universal amongst humans; it is widespread in the visual brain and responsive across visual modalities. Second, cognitive processing is based on contextual information, such as the depicted content, the intentions of the artist or the circumstances of the presentation of the artwork. Cognitive processing is partially top-down and varies between individuals according to their cultural experience. Processing in the two channels is parallel and largely independent. In the general case, an aesthetic experience is induced if processing in both channels is favorable, i.e., if there is resonance in the perceptual processing channel ("aesthetics of perception"), and successful mastering in the cognitive processing channel ("aesthetics of cognition"). I speculate that this combinatorial mechanism has evolved to mediate social bonding between members of a (cultural) group of people. Primary emotions can be elicited via both channels and modulate the degree of the aesthetic experience. Two special cases are discussed. First, in a subset of (post-)modern art, beauty no longer plays a prominent role. Second, in some forms of abstract art, beautiful form can be enjoyed with minimal cognitive processing. The model is applied to examples of Western art. Finally, implications of the model are discussed. In summary, the proposed model resolves the seeming contradiction between formalist perceptual approaches to aesthetic experience, which are based on the intrinsic beauty of artworks, and contextual approaches, which account for highly individual and culturally dependent aspects of aesthetics.

Study of charm and beauty production at HERA/H1 using dilepton events

International Nuclear Information System (INIS)

Goettlich, M.

2007-04-01

A measurement is presented which investigates the production of charm and beauty quarks in ep collisions at a centre-of-mass energy of 318 GeV. Data taken by the H1 detector at the HERA collider in the years 1999, 2000, 2004 and 2005 are analysed. The collected data correspond to an integrated luminosity of 221.6 pb -1 . This is the rst measurement of charm and beauty cross sections using HERA II data. Events with two or more jets of transverse momentum p t >5(4) GeV in the polar angular range 20 t >2(1) GeV in the polar angular ranges 30 1 2 2 2 , and for inelasticities 0.1 t rel of the leptons with respect to the jet they are associated to and the charge and angle correlation of the leptons are exploited to extract the fractions of charm and beauty events on a statistical basis. For the first time at H1, visible charm and beauty cross sections for the production of dijet and dilepton events are determined: σ(ep→ec anti cX→ejjμeX ' )=4.6±1.0(stat.)±0.5(sys.) pb, σ(ep→ec anti cX→ejjμμX ' )=2.7 ±0.9(stat.)±0.3(sys.) pb, σ(ep→eb anti bX→ejjμeX ' )=9.4±1.2(stat.)±0.9(sys.) pb, and σ(ep →eb anti bX→ejjμμX ' )=10.4 ± 1.5(stat.) ± 1.0(sys.) pb. To gain a deeper understanding of dilepton correlations in beauty events, differential dilepton cross sections are determined using the observable p t rel alone. The invariant mass m(μl), the transverse momentum p t (μl), the polar angle θ(μl) and the charge and angle correlation vertical stroke Δφ(μ 1 ,l 2 ) vertical stroke x Q(μ 1 ) x Q(l 2 ) of the dilepton system are investigated. In addition, differential jet cross sections are determined. The measurements are compared with leading order QCD calculations, supplemented with parton showers. The charm cross sections are consistent with the predictions, while the predicted beauty cross sections are somewhat lower than the measurement. The predicted differential beauty cross sections describe the shape of the measurements. (orig.)

Esthetics, eroticism and sex parity: Umberto Eco’s History of Beauty and History of Ugliness

Directory of Open Access Journals (Sweden)

Krzysztof Obremski

2012-01-01

Full Text Available The topic of comparative analysis which is presented in this article is The Story of Beauty and The Story of Ugliness edited by Umberto Eco. Even the covers of these books show the contrast between men and women. How esthetic values build a feedback with sexual parity? Ugly men look at beautiful women – this patriarchal discrimination can’t be cancelled either by the parity of sex in The Story of Beauty, nor men who twice outnumber them in The Story of Ugliness. Also as the unfair sex they are prior sex: they humiliate themselves and elevate women

The culture of complexion: the impacts of society's role in shaping the definition of beauty.

Science.gov (United States)

Carlock, Sarah; Russell, Brian

2015-05-01

The definition of beauty has evolved as the trends valued by the top of society change. For centuries, fair skin was a requirement of the Western definition of beauty; however, a shift in the 1920s made tanned skin the new standard. In this article, smoking and tanning are presented as risky behaviors that are perpetuated through industry advertising and exploitation of the authority of health professionals. The article further explores the culture of complexion in Western society before and after the 1920s as well as the consequences of tanning and efforts to rewrite society's definition of beauty.

Recreationists’ Perceptions of Scenic Beauty and Satisfaction at a Public Forest Managed for Endangered Wildlife

Directory of Open Access Journals (Sweden)

Ramesh Paudyal

2018-05-01

Full Text Available Prescribed burning and other active forest management treatments have been proven essential for maintaining suitable habitat conditions for many wildlife species, including the federally endangered red-cockaded woodpecker (RCW. This study examines the perception of forest management treatments of recreation users participating in various activities (hunting, hiking/backpacking, camping, off-highway vehicle riding, and canoeing/kayaking in terms of scenic beauty and recreation satisfaction. We used photographic images to capture various forest management treatments of different intensity levels and times after treatments, and assessed users’ perception of scenic beauty and recreation satisfaction. Results indicated variation among users participating in different recreation activities, but that good quality RCW habitats offered both higher scenic beauty and higher recreation satisfaction than poor quality habitats for most activity user groups. Finally, recreation satisfaction was statistically equal to perceived scenic beauty from both good and poor-quality RCW habitats for most of the activity user groups, thus suggesting the importance of scenic beauty of forest sites in determining recreation users’ attainment of visit satisfaction. Findings conclude that forest sites developed as good quality RCW habitats in the present state also offer quality experience to recreation users, thus supporting multi-objective forestry practices in public forests.

Increased mRNA level of subunit 1 cytochrome c oxidase (COXI) during wakefulness and after short-term sleep deprivation has been described in brain. We hypothesized that this might contribute to increased activity of cytochrome oxidase (COX) enzyme during wakefulness, as part of the mechanisms to provide sufficient amounts of adenosine triphosphate to meet increased neuronal energy demands. COX activity was measured in isolated mitochondria from different brain regions in groups of rats with 3 hours of spontaneous sleep, 3 hours of spontaneous wake, and 3 hours of sleep deprivation. The group with 3 hours of spontaneous wake was added to delineate the circadian component of changes in the enzyme activity. Northern blot analysis was performed to examine the mRNA levels of 2 subunits of the enzyme COXI and COXIV, encoded by mitochondrial and nuclear DNA, respectively. Laboratory of Biochemistry, Department of Animal Biology, and Center for Sleep and Respiratory Neurobiology, University of Pennsylvania. 2-month-old male Fischer rats (N = 21) implanted for polygraphic recording. For COX activity, there was a main effect by analysis of variance of experimental group (P sleep-deprived groups as compared to the sleep group. A main effect of brain region was also significant (P sleep. There is an increase in COX activity after both 3 hours of spontaneous wake and 3 hours of sleep deprivation as compared with 3 hours of spontaneous sleep in diverse brain regions, which could be, in part, explained by the increased levels of bigenomic transcripts of the enzyme. This likely contributes to increased adenosine triphosphate production during wakefulness.

Strength, functionality and beauty of university buildings in earthquake-prone countries

WADA, Akira

2018-01-01

Strength, functionality and beauty are the three qualities identifying well-designed architecture. For buildings in earthquake-prone countries such as Japan, emphasis on seismic safety frequently leads to the sacrifice of functionality and beauty. Therefore, it is important to develop new structural technologies that can ensure the seismic performance of a building without hampering the pursuit of functionality and beauty. The moment-resisting frame structures widely used for buildings in Japan are likely to experience weak-story collapse. Pin-supported walls, which can effectively enhance the structural story-by-story integrity of a building, were introduced to prevent such an unfavorable failure pattern in the seismic retrofit of an eleven-story building on a university campus in Tokyo, while also greatly aesthetically enhancing the façade of the building. The slight damage observed and monitoring records of the retrofitted building during the 2011 Tohoku earthquake in Japan demonstrate that the pin-supported walls worked as intended, protecting the building and guaranteeing the safety of its occupants during the earthquake.

The difference in the angular distributions between beauty quarks and antiquarks, referred to as the charge asymmetry, is measured for the first time in bb pair production at a hadron collider. The data used correspond to an integrated luminosity of 1.0 fb(-1) collected at 7 TeV center-of-mass energy in proton-proton collisions with the LHCb detector. The measurement is performed in three regions of the invariant mass of the bb system. The results obtained are A(C)(bb))(40 105 GeV/c(2)) = 1.6 ± 1.7 ± 0.6%, where A(C)(bb)) is defined as the asymmetry in the difference in rapidity between jets formed from the beauty quark and antiquark, where in each case the first uncertainty is statistical and the second systematic. The beauty jets are required to satisfy 2 20 GeV, and have an opening angle in the transverse plane Δ ϕ > 2.6 rad. These measurements are consistent with the predictions of the standard model.

Midface is a critical area for the aesthetics of the face. Despite malar hypoplasia is often combined with a class III malocclusion, there are few studies focusing on the results of a combined approach of malar implants and Le Fort I. We describe a new aesthetic analysis, named "beauty arch" analysis, for the assessment of sagittal projection of the malar region. We took a reference group of 74 Italian women participating in a national beauty contest in 2011 on which we performed our analysis. We used the ideal values to elaborate the surgical treatment planning of a second group of 45 consecutive female patients affected by skeletal class III malocclusion.Twenty-three patients undergo simultaneous Le Fort I osteotomy and malar implants. From the descriptive statistical comparison of the patients' values before and after orthognathic surgery and malar implants with the reference values, we observed how all parameters considered got closer to the ideal population. We consider our beauty arch a useful help for surgeon in the treatment planning of patients with skeletal malocclusions and malar implants.

Kahle, B.

2006-04-15

This thesis presents a measurement of beauty quark production in deep inelastic scattering at the ep-collider HERA at {radical}(s)=318 GeV. The measurement is based on data collected at the ZEUS detector in the years 2003/2004, using an integrated luminosity of 39 pb{sup -1}. In the analysis presented in this thesis, events were selected that contain a scattered electron, a jet and a muon inside the jet. The fraction of events from beauty quark production was extracted using the characteristic distribution of the transverse momenta of muons relative to the associated jets. The total visible cross section was measured to be: {sigma}{sup b} {sup anti} {sup b}(ep{yields}eb anti b X{yields}e jet{mu}X')=57.9{+-}5.8(stat.){sup +3.5}{sub -8.1}(syst.) pb in the kinematic region defined by: Q{sup 2}>4 GeV{sup 2}, y>0.05 und y<0.7, one jet originating from a beauty quark with: E{sup jet}{sub t,lab}>5 GeV und -2<{eta}{sup jet}<2.5 and a muon originating from a beauty quark decay (direct or indirect) included in this jet with: p{sup {mu}}{sub t}>1.5 GeV and {eta}{sup {mu}}>-1.6. Differential cross sections were measured in p{sup {mu}}{sub t} and {eta}{sup {mu}}, in p{sup jet}{sub t} and {eta}{sup jet} and in Q{sup 2}.Furthermore double differential cross sections d{sup 2}{sigma}/dQ{sup 2}dx were measured.

Asians increasingly seek non-surgical facial esthetic treatments, especially at younger ages. Published recommendations and clinical evidence mostly reference Western populations, but Asians differ from them in terms of attitudes to beauty, structural facial anatomy, and signs and rates of aging. A thorough knowledge of the key esthetic concerns and requirements for the Asian face is required to strategize appropriate facial esthetic treatments with botulinum toxin and hyaluronic acid (HA) fillers. The Asian Facial Aesthetics Expert Consensus Group met to develop consensus statements on concepts of facial beauty, key esthetic concerns, facial anatomy, and aging in Southeastern and Eastern Asians, as a prelude to developing consensus opinions on the cosmetic facial use of botulinum toxin and HA fillers in these populations. Beautiful and esthetically attractive people of all races share similarities in appearance while retaining distinct ethnic features. Asians between the third and sixth decades age well compared with age-matched Caucasians. Younger Asians' increasing requests for injectable treatments to improve facial shape and three-dimensionality often reflect a desire to correct underlying facial structural deficiencies or weaknesses that detract from ideals of facial beauty. Facial esthetic treatments in Asians are not aimed at Westernization, but rather the optimization of intrinsic Asian ethnic features, or correction of specific underlying structural features that are perceived as deficiencies. Thus, overall facial attractiveness is enhanced while retaining esthetic characteristics of Asian ethnicity. Because Asian patients age differently than Western patients, different management and treatment planning strategies are utilized.

Sleep less and bite more: sleep disorders associated with occlusal loads during sleep.

2013-04-01

Occlusal overload during sleep is a significant clinical issue that has negative impacts on the maintenance of teeth and the longevity of dental prostheses. Sleep is usually viewed as an 'out-of-functional' mode for masticatory muscles. However, orodental structures and prostheses are not free from occlusal loads during sleep since masticatory muscles can be activated at a low level within normal sleep continuity. Thus, an increase in masticatory muscle contractions, by whatever the cause, can be associated with a risk of increased occlusal loads during sleep. Among such conditions, sleep bruxism (SB) is a type of sleep-related movement disorders with potential load challenge to the tooth and orofacial structures. Patients with SB usually report frequent tooth grinding noises during sleep and there is a consecutive increase in number and strength of rhythmic masticatory muscle activity (RMMA). Other types of masticatory muscle contractions can be non-specifically activated during sleep, such as brief contractions with tooth tapping, sleep talking, non-rhythmic contractions related to non-specific body movements, etc.; these occur more frequently in sleep disorders. Studies have shown that clinical signs and symptoms of SB can be found in patients with sleep disorders. In addition, sleep becomes compromised with aging process, and a prevalence of most sleep disorders is high in the elderly populations, in which prosthodontic rehabilitations are more required. Therefore, the recognition and understanding of the role of sleep disorders can provide a comprehensive vision for prosthodontic rehabilitations when prosthodontists manage complex orodental cases needing interdisciplinary collaborations between dentistry and sleep medicine.

Sleep-Active Neurons: Conserved Motors of Sleep

Science.gov (United States)

Bringmann, Henrik

2018-01-01

Sleep is crucial for survival and well-being. This behavioral and physiological state has been studied in all major genetically accessible model animals, including rodents, fish, flies, and worms. Genetic and optogenetic studies have identified several neurons that control sleep, making it now possible to compare circuit mechanisms across species. The “motor” of sleep across animal species is formed by neurons that depolarize at the onset of sleep to actively induce this state by directly inhibiting wakefulness. These sleep-inducing neurons are themselves controlled by inhibitory or activating upstream pathways, which act as the “drivers” of the sleep motor: arousal inhibits “sleep-active” neurons whereas various sleep-promoting “tiredness” pathways converge onto sleep-active neurons to depolarize them. This review provides the first overview of sleep-active neurons across the major model animals. The occurrence of sleep-active neurons and their regulation by upstream pathways in both vertebrate and invertebrate species suggests that these neurons are general and ancient components that evolved early in the history of nervous systems.

Measurement of beauty quark production from dimuon events with the ZEUS detector at HERA II

2011-10-01

In this thesis, a measurement of beauty quark production via the process ep→e'b anti bX→e'μμX in electron-proton collisions at HERA using a data sample recorded by the ZEUS detector in the years 2003-2007, corresponding to an integrated luminosity of 376 pb -1 , is presented. A low transverse momentum threshold for muon identification in combination with the large rapidity coverage of the ZEUS muon-detection system gives access to essentially the full phase space for beauty quark production. Dimuon charge correlations as well as hadronic isolation and the mass of the dimuon system were used to separate the beauty signal from backgrounds. Visible, differential and total cross sections for beauty quark production were measured and compared to next-to-leading order QCD calculations and previous measurements. In addition, a first search for QCD instanton-induced processes containing both a charm- and beauty-quark pair in dimuon events was performed. In order to differentiate between beauty and instanton events, discriminating observables sensitive to the hadronic final state, so-called event shape variables, were used in combination with the dimuon requirement. As technical part of this thesis, the reconstruction algorithm for so-called energy flow objects (EFOs) was modified. EFOs contain the combined information of primary and secondary vertex-fitted tracks as well as CAL energy measurements. The modification considers additional tracks close to but not fitted to the primary vertex and which fulfill reasonable track and impact parameter requirements. As a result, the efficiency to reconstruct muon candidates with high impact parameter values as energy flow objects was increased. (orig.)

This study's objective was to investigate the relationship between a variable-number tandem-repeat (VNTR) Period 3 gene (PER3) polymorphism and sleep adaptation to stressful urban environments. Seventy-five (49 female) African American participants (ages 18-35 years) living in neighbourhoods with high rates of violent crime were selected for the study based on converging criteria for good or poor sleep. Categorization of sleep quality was based on the Insomnia Severity Index (ISI), estimates of typical sleep duration and sleep efficiency. Other assessments included the Fear of Sleep Index (FOSI) and City Stress Inventory (CSI). Whole blood DNA was analysed for the 4 and 5 VNTR alleles using polymerase chain reaction (PCR) and restrictive enzyme digestion. Fifty-seven per cent of those who were homo- or heterozygous for the 4-repeat allele were poor sleepers versus 25% of those homozygous for the 5-repeat allele; χ 2  = 4.17, P = 0.041. In a logistic regression model with all the variables with significant bivariate relationships to sleep quality group, FOSI was the only significant predictor (χ 2  = 5.68, P = 0.017). FOSI scores were higher among those with the 4-repeat allele (t = 2.66, P = 0.013). The PER3 4 and 5 VNTR polymorphisms appear to influence sensitivity to the effects of stressful urban environments on sleep. While FOSI was the only variable associated independently with sleep quality category, the candidate vulnerability allele was also associated with greater 'fear of sleep'. © 2016 European Sleep Research Society.

Inbred long-sleep (ILS) and short-sleep (ISS) mice show significant central nervous system-mediated differences in sleep time for sedative dose of ethanol and are frequently used as a rodent model for ethanol sensitivity. In this study, we have used complementary DNA (cDNA) array hybridization methodology to identify genes that are differentially expressed between the brains of ILS and ISS mice. To carry out this analysis, we used both the gene discovery array (GDA) and the Mouse GEM 1 Microarray. GDA consists of 18,378 nonredundant mouse cDNA clones on a single nylon filter. Complex probes were prepared from total brain mRNA of ILS or ISS mice by using reverse transcription and 33P labeling. The labeled probes were hybridized in parallel to the gene array filters. Data from GDA experiments were analyzed with SQL-Plus and Oracle 8. The GEM microarray includes 8,730 sequence-verified clones on a glass chip. Two fluorescently labeled probes were used to hybridize a microarray simultaneously. Data from GEM experiments were analyzed by using the GEMTools software package (Incyte). Differentially expressed genes identified from each method were confirmed by relative quantitative reverse transcription-polymerase chain reaction (RT-PCR). A total of 41 genes or expressed sequence tags (ESTs) display significant expression level differences between brains of ILS and ISS mice after GDA, GEM1 hybridization, and quantitative RT-PCR confirmation. Among them, 18 clones were expressed higher in ILS mice, and 23 clones were expressed higher in ISS mice. The individual gene or EST's function and mapping information have been analyzed. This study identified 41 genes that are differentially expressed between brains of ILS and ISS mice. Some of them may have biological relevance in mediation of phenotypic variation between ILS and ISS mice for ethanol sensitivity. This study also demonstrates that parallel gene expression comparison with high-density cDNA arrays is a rapid and

The beautiful invisible creativity, imagination, and theoretical physics

Challenging the image of theoretical physics as a dry discipline, The Beautiful Invisible shows that this highly abstract science is in fact teeming with beautiful concepts, and the task of imagining them demands profound creativity, just as creative as the work of poets or magical realist novelists such as Borges and Musil. "A good scientific theory is like a symbolic tale, an allegory of reality," writes Giovanni Vignale, as he uncovers the unexpected links between theoretical physics and artistic creativity. In engaging and at times poetic prose, and with ample quotations from many of the writers he admires, Vignale presents his own unorthodox accounts of fundamental theoretical concepts such as Newtonian mechanics, superconductivity, and Einstein's theory of relativity, illuminating their profound implications. Throughout, the author treats readers to glimpses of physics as "exercised in the still night, when only the moon rages." Indeed, as we delve behind now-familiar concepts such as "electron spin" an...

The Large Hadron Collider experiments will search for physics phenomena beyond the Standard Model. Highly sensitive tests of beauty hadrons will represent an alternative approach to this research. The analysis of complex decay chains of the beauty hadrons have to efficiently extract the detector tracks made by these reactions and reject other events in order to make sufficiently precise measurement. This places severe demands on the software used to analyze the B-physics data. The ATLAS B-physics group has written a series of tools and algorithms for performing these tasks, to be run within the ATLAS offline software framework Athena. This paper describes this analysis suite, paying particular attention to mechanisms for handling combinatorics, interfaces to secondary vertex fitting packages, B-flavor tagging tools and finally Monte Carlo true information association to pursue simulation data in process of the software validations which is an important part of the development of the physics analysis tools

Full Text Available There is no doubt that people find flowers beautiful. Surprisingly, we know very little about the actual properties which make flowers so appealing to humans. Although the evolutionary aesthetics provides some theories concerning generally preferred flower traits, empirical evidence is largely missing. In this study, we used an online survey in which residents of the Czech Republic (n = 2006 rated the perceived beauty of 52 flower stimuli of diverse shapes and colors. Colored flowers were preferred over their uncolored versions. When controlling for flower shape, we found an unequal preference for different flower colors, blue being the most and yellow the least preferred. In the overall assessment of beauty, shape was more important than color. Prototypical flowers, i.e., radially symmetrical flowers with low complexity, were rated as the most beautiful. We also found a positive effect of sharp flower contours and blue color on the overall rating of flower beauty. The results may serve as a basis for further studies in some areas of the people-plant interaction research.

Sleep duration affects the health of children and adolescents. Shorter sleep durations have been associated with poorer academic performance, unintentional injuries, and obesity in adolescents. This study extends our understanding of how adolescents perceive and deal with their sleep issues. General education classes were randomly selected from a convenience sample of three high schools in the Midwest. Three hundred eighty-four ninth- to twelfth-grade students (57%) completed a self-administered valid and reliable questionnaire on sleep behaviors and perceptions of sleep. Most respondents (91.9%) obtained inadequate sleep (sleep each week night. The majority indicated that not getting enough sleep had the following effects on them: being more tired during the day (93.7%), having difficulty paying attention (83.6%), lower grades (60.8%), increase in stress (59.0%), and having difficulty getting along with others (57.7%). Some students reported engaging in harmful behaviors to help them sleep: taking sleeping pills (6.0%), smoking a cigarette to relax (5.7%), and drinking alcohol in the evening (2.9%). Students who received fewer hours of sleep were significantly more likely to report being stressed (p = .02) and were more likely to be overweight (p = .04). Inadequate sleep time may be contributing to adolescent health problems such as increased stress and obesity. Findings indicate a need for sleep hygiene education for adolescents and their parents. A long-term solution to chronic sleep deprivation among high school students could include delaying high school start times, such as was done successfully in the Minneapolis Public School District.

Obstructive sleep apnea alters sleep stage transition dynamics.

Full Text Available Enhanced characterization of sleep architecture, compared with routine polysomnographic metrics such as stage percentages and sleep efficiency, may improve the predictive phenotyping of fragmented sleep. One approach involves using stage transition analysis to characterize sleep continuity.We analyzed hypnograms from Sleep Heart Health Study (SHHS participants using the following stage designations: wake after sleep onset (WASO, non-rapid eye movement (NREM sleep, and REM sleep. We show that individual patient hypnograms contain insufficient number of bouts to adequately describe the transition kinetics, necessitating pooling of data. We compared a control group of individuals free of medications, obstructive sleep apnea (OSA, medical co-morbidities, or sleepiness (n = 374 with mild (n = 496 or severe OSA (n = 338. WASO, REM sleep, and NREM sleep bout durations exhibited multi-exponential temporal dynamics. The presence of OSA accelerated the "decay" rate of NREM and REM sleep bouts, resulting in instability manifesting as shorter bouts and increased number of stage transitions. For WASO bouts, previously attributed to a power law process, a multi-exponential decay described the data well. Simulations demonstrated that a multi-exponential process can mimic a power law distribution.OSA alters sleep architecture dynamics by decreasing the temporal stability of NREM and REM sleep bouts. Multi-exponential fitting is superior to routine mono-exponential fitting, and may thus provide improved predictive metrics of sleep continuity. However, because a single night of sleep contains insufficient transitions to characterize these dynamics, extended monitoring of sleep, probably at home, would be necessary for individualized clinical application.

Lifetime measurements of the strange beauty meson and beauty baryons at LEP

Last experimental results on the lifetimes of B s 0 mesons and beauty baryons from the LEP experiments ALEPH, DELPHI and OPAL are presented. LEP averages for the lifetimes of B s 0 and Λ b are compared to lifetimes of B d 0 and B + and to the average b hadron lifetime. The precision of these measurements begins to be suitable to test the theoretical predictions of 10-15% differences between the lifetimes of b baryons and mesons, but does not allow a test of the few percent difference expected between B d 0 and B + lifetimes. The data show a significant evidence (3 σ) for lifetime differences between b mesons and b baryons. (author). 4 refs., 9 figs

To describe the sleep patterns and problems in children aged between 12 and 36 mo of age. This cross sectional survey was collected over a span of 1 y in Advanced Pediatric Centre, PGIMER, Chandigarh and crèches of Chandigarh. Children in the age group of 12 to 36 mo were included in study. Children with chronic illness, developmental delay, seizure disorder and lack of consent were excluded. A total of 368 children were enrolled. Main outcome measures were sleep duration over 1 to 3 y of life; sleep behavior at onset, during and waking of sleep and parent reported sleep problems and their predictors. The average duration of sleep was 12.5 h (S.D = 1.9). The mean total sleep duration and mean day time sleep duration decreased, while mean night time sleep increased as the age advanced from 12 to 36 mo. Following were the frequency of sleep habits seen in the index study; bed time routine was seen only in 68(18.5 %), a regular bed time ritual was seen in 281(76.4 %), 329(89.4 %) children frequently required 0-20 min time to fall asleep, 11(3 %) parents used sleep inducing drugs. Night waking (1 to 3 times a night) was seen in 297(80.7 %) and its frequency declined with age. Parent reported sleep problems were seen in 12.8 % (47/368). Lack of co-sleeping and night waking were considered as strongest predictors of parent reported sleep problems. Toddlers' sleep duration, night waking behavior, and day time naps decrease as the age progress while night time sleep duration increases with age. Lack of co-sleeping and night waking are considered as strongest predictors of parent reported sleep problems.

Sleep deprivation disrupts the lives of millions of people every day and has a profound impact on the molecular biology of the brain. These effects begin as changes within a neuron, at the DNA and RNA level, and result in alterations in neuronal plasticity and dysregulation of many cognitive functions including learning and memory. The epigenome plays a critical role in regulating gene expression in the context of memory storage. In this review article, we begin by describing the effects of e...

Immediate postarousal sleep dynamics: an important determinant of sleep stability in obstructive sleep apnea.

Science.gov (United States)

Younes, Magdy; Hanly, Patrick J

2016-04-01

Arousability from sleep is increasingly recognized as an important determinant of the clinical spectrum of sleep disordered breathing (SDB). Patients with SDB display a wide range of arousability. The reason for these differences is not known. We hypothesized that differences in the speed with which sleep deepens following arousals/awakenings (postarousal sleep dynamics) is a major determinant of these differences in arousability in patients with SDB. We analyzed 40 preexisting clinical polysomnography records from patients with a range of SDB severity (apnea-hypopnea index 5-135/h). Sleep depth was determined every 3 s using the odds ratio product (ORP) method, a continuous index of sleep depth (0 = deep sleep, 2.5 = full wakefulness) that correlates strongly (r = 0.98) with arousability (Younes M, Ostrowski M, Soiferman M, Younes H, Younes M, Raneri J, and Hanly P. Sleep 38: 641-654, 2015). Time course of ORP was determined from end of arousal until the next arousal. All arousals were analyzed (142 ± 65/polysomnogram). ORP increased from 0.58 ± 0.32 during sleep to 1.67 ± 0.35 during arousals. ORP immediately (first 9 s) following arousals/awakenings (ORP-9) ranged from 0.21(very deep sleep) to 1.71 (highly arousable state) in different patients. In patients with high ORP-9, sleep deepened slowly (over minutes) beyond 9 s but only if no arousals/awakenings recurred. ORP-9 correlated strongly with average non-rapid eye movement sleep depth (r = 0.87, P sleep architecture. We conclude that postarousal sleep dynamics are highly variable among patients with sleep-disordered breathing and largely determine average sleep depth and continuity.

African Americans (AAs) have a higher prevalence of sleep disorders than other racial/ethnic groups. However, little is known about the relationships among individual and neighborhood factors related to sleep quality in AAs. The purposes of this study were to (1) describe beliefs about sleep, sleep hygiene behaviors, and sleep quality among AAs; and (2) examine the relationships among sociodemographic characteristics, neighborhood environment, beliefs about sleep, sleep hygiene behaviors, and sleep quality. We conducted a cross-sectional study of 252 AA men and women in the Greater New Haven, CT, USA community. We assessed their sociodemographic characteristics, neighborhood environment, beliefs about sleep, sleep hygiene, and sleep quality with the following measures, respectively: the Neighborhood Environment Scale, the brief version of Dysfunctional Beliefs and Attitudes about Sleep, the Sleep Hygiene Practice Scale, the Pittsburgh Sleep Quality Index. We performed descriptive statistics, correlations and multiple hierarchical regression. About 72% of the participants (mean age: 53.88 ± 14.17 years, 77.8% women) reported experiencing sleep disturbance. People with poor sleep quality were more likely to report poorer neighborhood social environment (social cohesion), poorer overall neighborhood environment, more dysfunctional beliefs toward sleep, and poorer sleep hygiene than those who had good sleep quality. In the final multivariate model that controlled for a number of chronic comorbid conditions, neighborhood environment, beliefs about sleep, and sleep hygiene behaviors were significantly associated with sleep quality. Future efforts are needed to improve sleep among AAs by considering both the individual's belief about sleep, sleep hygiene behaviors and neighborhood factors.

Our investigation aims to assess the impact of symptoms of maternal sleep-disordered breathing, specifically sleep apnea risk and daytime sleepiness, on fetal leukocyte telomere length. Pregnant women were recruited upon hospital delivery admission. Sleep exposure outcomes were measured using the Berlin Questionnaire to quantify sleep apnea and the Epworth Sleepiness Scale to measure daytime sleepiness. Participants were classified as "High Risk" or "Low Risk" for sleep apnea based on responses to the Berlin, while "Normal" or "Abnormal" daytime sleepiness was determined based on responses to the Epworth. Neonatal umbilical cord blood samples (N = 67) were collected and genomic DNA was isolated from cord blood leukocytes using Quantitative PCR. A ratio of relative telomere length was derived by telomere repeat copy number and single copy gene copy number (T/S ratio) and used to compare telomere lengths. Bootstrap and ANOVA statistical procedures were employed. On the Berlin, 68.7% of participants were classified as Low Risk while 31.3% were classified as High Risk for sleep apnea. According to the Epworth scale, 80.6% were determined to have Normal daytime sleepiness, and 19.4% were found to have Abnormal daytime sleepiness. The T/S ratio among pregnant women at High Risk for sleep apnea was significantly shorter than for those at Low Risk (P value sleep disordered breathing during pregnancy, and suggest sleep disordered breathing as a possible mechanism of accelerated chromosomal aging. © 2015 Associated Professional Sleep Societies, LLC.

Previously, we found a significant association between the dopamine D2 receptor gene polymorphism Taq IA and sudden onset of sleep in patients with Parkinson disease. Here we evaluated the association between the preprohypocretin (-909T/C), (-22C/T), and (-20C/A) polymorphisms and sudden onset of sleep in the same population of patients with Parkinson disease. We conducted an association study analyzing the distribution of preprohypocretin polymorphisms in Germanic, caucasian Parkinson disease patients with and without sudden onset of sleep, matched according to drug therapy, disease duration, sex, and age. Movement disorders section at a university hospital. 132 Parkinson disease patients with sudden onset of sleep and 132 Parkinson disease patients without sudden onset of sleep. Blood samples were taken from each participant and used for DNA extraction. Polymorphisms were analyzed by established polymerase chain reaction protocols or direct sequencing. The variant allele T of the (-909T/C) preprohypocretin polymorphism was more commonly found in Parkinson disease patients with sudden onset of sleep. Statistical analysis showed that there were significant differences in the genotype (P = .024) and allele (P = .018) distribution between both groups. For heterozygous and homozygous carriers of allele T, the genotype relative-risk estimates for the presence of sudden onset of sleep were 2.01 (95% confidence interval: 0.76-5.34) and 2.81 (95% confidence interval: 1.09-7.25), respectively. Our results show a significant association between the (-909T/C) preprohypocretin polymorphism and sudden onset of sleep in Parkinson disease. However, we could not demonstrate any interaction between the Taq IA and (-909T/C) polymorphisms with respect to the occurrence of sudden onset of sleep, suggesting that multiple genetic factors may contribute to the pathogenesis of this phenomenon.

2016-06-01

Full Text Available The aim of this paper was to validate factors affecting the in-stand landscape quality and how important each factor was in determining scenic beauty of natural secondary forests. The study was limited to 23 stand-level cases of natural secondary forests in Shen Zhen city in southern China. Typical samples of photographs and public estimations were applied to evaluate scenic beauty inside the natural secondary forests. The major factors were then selected by multiple linear-regression analysis and a model between scenic beauty estimation (SBE values and in-stand landscape features was established. Rise in crown density, fall in plant litter, glow in color of trunk, fall in arbor richness, and rise in visible distance increased scenic beauty values of in-stand landscape. These five factors significantly explained the differences in scenic beauty, and together accounted for 45% of total variance in SBEs. Personal factors (e.g. gender, age and education did not significantly affect the ratings of landscape photos, although variations of landscape quality were affected by some personal factors. Results of this study will assist policymakers, silviculturists and planners in landscape design and management of natural secondary forests in Shenzhen city. People can improve the scenic beauty values by pruning branches and clearing plant litter, which subsequently improve the forest health and contribute to forest recreation.

Selective visual attention for ugly and beautiful body parts in eating disorders.

Jansen, Anita; Nederkoorn, Chantal; Mulkens, Sandra

2005-02-01

Body image disturbance is characteristic of eating disorders, and current treatments use body exposure to reduce bad body feelings. There is however little known about the cognitive effects of body exposure. In the present study, eye movement registration (electroculography) as a direct index of selective visual attention was used while eating symptomatic and normal control participants were exposed to digitalized pictures of their own body and control bodies. The data showed a decreased focus on their own 'beautiful' body parts in the high symptomatic participants, whereas inspection of their own 'ugly' body parts was given priority. In the normal control group a self-serving cognitive bias was found: they focused more on their own 'beautiful' body parts and less on their own 'ugly' body parts. When viewing other bodies the pattern was reversed: high symptom participants allocated their attention to the beautiful parts of other bodies, whereas normal controls concentrated on the ugly parts of the other bodies. From the present findings the hypothesis follows that a change in the processing of information might be needed for body exposure to be successful.

Brains versus beauty in the knowledge economy

Full Text Available Orientation: It is a widely held belief that attractive people generally experience an easier life and that the door to success is opened by perfect bone structure and a sparkling smile. However, attractiveness might play a far lesser role in individual’s achieving their objectives than has previously been thought. Is it possible that an individual’s qualifications may have a greater influence on the perceptions of managers who assess the suitability of a candidate of a knowledge worker? Research purpose: The study sets out to examine the relative predictive power of physical attractiveness and qualifications in the decision to hire a knowledge worker. Motivation for the study: The research was motivated by a desire to explore the presence of bias in the decision-making process when seemingly rational individuals are exposed to factors such as physical attractiveness of a job candidate and then faced with a decision on whether to hire them. Research design, approach and method: A two-phased experimental design was applied to investigate the existence and strength of the beauty premium amongst a group of managers who were provided with fictitious resumes coupled with photographs of the applicants. These managers were requested to make a hiring decision based on the information supplied. Main findings: Although results confirm the existence of a beauty premium, it was relatively weak. It indicated that qualifications have a greater influence on a manager’s perception of the suitability of a candidate to fill a position of a knowledge worker. Practical or managerial implications: The research draws attention to the possibility of bias in selection decisions and proposes ways in which such potential bias can be limited. Contribution: This study contributes to knowledge concerning the existence or otherwise of a so-called beauty premium, with particular reference to its impact in the knowledge economy.

Full Text Available The Brazilian market has shown growth in some sectors, due to increased consumer purchasing power over the years. Among these markets are the food market that passes through the search for healthy foods trend, and cosmetics market, whose products have become increasingly important in people’s lives, who constantly seek improvement of beauty. These markets have given rise to a new, the nutricosmetics market, that is food that aim to improve the beauty from the inside out. The nutricosmetics meet both the need for food as beauty, so this article aims to identify the values ​​associated with these two needs together, aiming to capture the perceptions of individuals about this product. For this, a literature review on the subject was made in addition to the implementation of the Focus Group, the Laddering and Conjoint Analysis, appropriate techniques to analyze new products. The results showed that consumers have sought to improve the beauty as a lifestyle, through the adoption of attitudes and healthy habits, since it makes them feel better about themselves and makes them more successful in social relations. It was observed that the most valued aspect in relation to nutricosmetics is the scientific basis, indicating a difficulty of launching new products. It was considered, finally, that the nutricosmetics represent that there is a fine line between the values ​​related to food and related to beauty.

Women and men integrate facial information differently in appraising the beauty of a face

OpenAIRE

Gill, Daniel

2017-01-01

Facial beauty plays a crucial role in social interactions, particularly in mating and reproduction. Therefore, the perceptual and cognitive mechanisms used for facial beauty assessment should be susceptible to different evolutionary and cultural pressures across genders and thus shape different observational appraising strategies. Using a novel approach, I evaluated the observers' subjective and unique importance given to specific facial attributes: eyes, nose, lips, and hair, and their spati...

The aim of this study was to synthesize the literature on the cultural aspects of sleep and their relevance to behavioral sleep research. A narrative synthesis of the existing literature on sleep was conducted with a focus on its biological, sociological, political, and anthropological aspects. This synthesis was guided by the PEN-3 cultural model, developed by the primary author. The findings highlight the cross-cultural contexts within which people sleep and the role of varied sleeping arrangements in influencing sleep behavior and perspectives. Furthermore, the contexts in which sleep occurs, coupled with the influence of the family, and the positive aspects of sleep helped illustrate why cultural aspects of sleep are vital for a broader understanding of sleep. The authors conclude by highlighting the need to integrate studies on the biological, sociological, and political aspects of sleep. Our examination of the literature strongly suggests that careful assessment of epidemiological and clinical sleep data should consider the cultural aspects of sleep as well as the context in which sleep occurs, the role of the family, and positive aspects of sleep.

Photographic emulsion versus bubble chambers in charm and beauty searches

International Nuclear Information System (INIS)

Sacton, J.

1984-01-01

This chapter discusses the use of visual detectors in the search for charm and other flavors. The photographic emulsion and the bubble chamber techniques are compared. The main difficulties encounted in searching for charmed and beautiful hadrons are related to the short lifetimes of these particles and to their small production cross-sections, even at SPS energies. Resolution, visibility, the data analysis rate, and exposure time are considered. Most of the charmed hadrons present a large variety of decay modes of which only a fraction has been identified to date. First results from CESR indicate that the average charged particle multiplicity in the hadronic decay of beautiful hadrons is as high as 6.31 + or - 0.35; no B meson decay has yet been kinematically reconstructed. The case of hadronic charmed particle production at SPS energies is examined. The data show that 1) the bubble chamber technique (high resolution or holographic optics) is well suited to the study of charmed hadrons with lifetimes in the range 10 -13 to 10 -12 s; 2) searches for beautiful hadrons remain presently a domain for triggered emulsion experiments due to the smallness of the production cross-sections (provided the lifetime is not much shorter than 10 -14 s); and 3) for particles of lifetimes shorter than a few times 10 -14 s the emulsion technique is still without competitor

Sleep is essential for recovery and performance in elite athletes. While it is generally assumed that exercise benefits sleep, high training load may jeopardize sleep and hence limit adequate recovery. To examine this, the current study assessed objective sleep quantity and sleep stage distributions in elite athletes and calculated their association with perceived training load. Mixed-methods. Perceived training load, actigraphy and one-channel EEG recordings were collected among 98 elite athletes during 7 consecutive days of regular training. Actigraphy revealed total sleep durations of 7:50±1:08h, sleep onset latencies of 13±15min, wake after sleep onset of 33±17min and sleep efficiencies of 88±5%. Distribution of sleep stages indicated 51±9% light sleep, 21±8% deep sleep, and 27±7% REM sleep. On average, perceived training load was 5.40±2.50 (scale 1-10), showing large daily variability. Mixed-effects models revealed no alteration in sleep quantity or sleep stage distributions as a function of day-to-day variation in preceding training load (all p's>.05). Results indicate healthy sleep durations, but elevated wake after sleep onset, suggesting a potential need for sleep optimization. Large proportions of deep sleep potentially reflect an elevated recovery need. With sleep quantity and sleep stage distributions remaining irresponsive to variations in perceived training load, it is questionable whether athletes' current sleep provides sufficient recovery after strenuous exercise.

It is a well-established view amongst economists that good-looking people have a better chance of employment and can earn more than those who are less physically attractive. A “beauty premium” is particularly apparent in jobs where there is a productivity gain associated with good looks, though this is different for women and men, and varies across countries. People also sort into occupations according to the relative returns to their physical characteristics; good-looking people take jobs wh...

Parent-Offspring Conflict over Mating: The Case of Beauty

Directory of Open Access Journals (Sweden)

Menelaos Apostolou

2008-04-01

Full Text Available In pre-industrial societies parents exercise a strong influence over the mating decisions of their offspring. As modern pre-industrial societies approximate the way of life in ancestral human societies, human mating behavior should be seen as the outcome of a co-evolutionary process between parental and offspring's mating choice. Both parents and offspring have evolved mating preferences, which enable them to select those mates and in-laws who maximize their inclusive fitness. Following Trivers' (1974 theory of parent-offspring conflict, it is hypothesized that in-law and mating preferences substantially overlap, but also differ with respect to the beauty trait of a mating candidate. This hypothesis is tested on a sample of 292 parents. It is found that the two sets of preferences are strongly correlated, while beauty is preferred significantly more in a mating partner than in an in-law.

REM sleep complicates period adding bifurcations from monophasic to polyphasic sleep behavior in a sleep-wake regulatory network model for human sleep

OpenAIRE

Kalmbach, K.; Booth, V.; Behn, C. G. Diniz

2017-01-01

The structure of human sleep changes across development as it consolidates from the polyphasic sleep of infants to the single nighttime sleep period typical in adults. Across this same developmental period, time scales of the homeostatic sleep drive, the physiological drive to sleep that increases with time spent awake, also change and presumably govern the transition from polyphasic to monophasic sleep behavior. Using a physiologically-based, sleep-wake regulatory network model for human sle...

Sustained sleep fragmentation induces sleep homeostasis in mice

Study Objectives: Sleep fragmentation (SF) is an integral feature of sleep apnea and other prevalent sleep disorders. Although the effect of repetitive arousals on cognitive performance is well documented, the effects of long-term SF on electroencephalography (EEG) and molecular markers of sleep homeostasis remain poorly investigated. To address this question, we developed a mouse model of chronic SF and characterized its effect on EEG spectral frequencies and the expression of genes previously linked to sleep homeostasis including clock genes, heat shock proteins, and plasticity-related genes. Design: N/A. Setting: Animal sleep research laboratory. Participants : Sixty-six C57BL6/J adult mice. Interventions: Instrumental sleep disruption at a rate of 60/h during 14 days Measurements and Results: Locomotor activity and EEG were recorded during 14 days of SF followed by recovery for 2 days. Despite a dramatic number of arousals and decreased sleep bout duration, SF minimally reduced total quantity of sleep and did not significantly alter its circadian distribution. Spectral analysis during SF revealed a homeostatic drive for slow wave activity (SWA; 1-4 Hz) and other frequencies as well (4-40 Hz). Recordings during recovery revealed slow wave sleep consolidation and a transient rebound in SWA, and paradoxical sleep duration. The expression of selected genes was not induced following chronic SF. Conclusions: Chronic sleep fragmentation (SF) increased sleep pressure confirming that altered quality with preserved quantity triggers core sleep homeostasis mechanisms. However, it did not induce the expression of genes induced by sleep loss, suggesting that these molecular pathways are not sustainably activated in chronic diseases involving SF.

Chronic sleep deprivation is common among workers, and has been associated with negative work outcomes, including absenteeism and occupational accidents. The objective of the present study is to characterize reciprocal relationships between sleep and work. Specifically, we examined how sleep impacts work performance and how work affects sleep in individuals not at-risk for a sleep disorder; assessed work performance outcomes for individuals at-risk for sleep disorders, including insomnia, obstructive sleep apnea (OSA) and restless legs syndrome (RLS); and characterized work performance impairments in shift workers (SW) at-risk for shift work sleep disorders relative to SW and day workers. One-thousand Americans who work 30 h per week or more were asked questions about employment, work performance and sleep in the National Sleep Foundation's 2008 Sleep in America telephone poll. Long work hours were associated with shorter sleep times, and shorter sleep times were associated with more work impairments. Thirty-seven percent of respondents were classified as at-risk for any sleep disorder. These individuals had more negative work outcomes as compared with those not at-risk for a sleep disorder. Presenteeism was a significant problem for individuals with insomnia symptoms, OSA and RLS as compared with respondents not at-risk. These results suggest that long work hours may contribute to chronic sleep loss, which may in turn result in work impairment. Risk for sleep disorders substantially increases the likelihood of negative work outcomes, including occupational accidents, absenteeism and presenteeism. © 2010 European Sleep Research Society.

Beauty matters: social preferences in a three-person ultimatum game.

2015-01-01

Preference for beauty is human nature, as previous behavior studies have supported the notion of "beauty premium" in which attractive people were more easily to get promoted and receive higher salaries. In the present study, 29 males were recruited to participate in a three-person ultimatum game (UG) including a proposer, a responder and a powerless third player. Each subject, playing as the responder, had to decide whether to accept an offer from the allocator both for himself and a female third person. We aimed to elucidate how the facial attractiveness of the female subject affected the male subjects' fairness and decision-making in social exchanges. Frontal feedback-related negativity (FRN) in response to four offers in an attractive-face condition revealed no significant differences between offers; however, when the companion was an unattractive female, an "unfair/fair" offer, which assigned a lower share to the responder and a fair share to the third player, elicited the largest FRN. Furthermore, when the third player was offered the smallest amount ("fair/unfair" offer), a larger FRN was generated in an attractive-face condition than unattractive-face condition. In the "unfair/fair" offer condition in which subjects received a smaller allocation than the third person, the beauty of their female counterparts attenuated subjects' aversion to inequality, resulting in a less negative FRN in the frontal region and an increased acceptance ratio. However, the influence of the third player's facial attractiveness only affected the early evaluation stage: late P300 was found to be immune to the "beauty premium". Under the two face conditions, P300 was smallest following an "unfair/fair" offer, whereas the amplitudes in the other three offer conditions exhibited no significant differences. In addition, the differentiated neural features of processing facial attractiveness were also determined and indexed by four event-related potentials (ERP) components: N170, frontal

Association Between Fear and Beauty Evaluation of Snakes: Cross-Cultural Findings

According to the fear module theory, humans are evolutionarily predisposed to perceive snakes as prioritized stimuli and exhibit a fast emotional and behavioral response toward them. In Europe, highly dangerous snake species are distributed almost exclusively in the Mediterranean and Caspian areas. While the risk of a snakebite is relatively low in Central Europe, Azerbaijan, on the other hand, has a high occurrence of the deadly venomous Levant viper (Macrovipera lebetina). We hypothesize that co-habitation with this dangerous snake has shaped the way in which humans evaluate snake species resembling it. For that purpose, we asked respondents from the Czech Republic and Azerbaijan to rank photographs depicting 36 snake species according to perceived fear and beauty. The results revealed a high cross-cultural agreement in both evaluations (fear r2 = 0.683, p < 0.0001; beauty: r2 = 0.816, p < 0.0001). Snakes species eliciting higher fear tend to be also perceived as more beautiful, yet people are able to clearly distinguish between these two dimensions. Deadly venomous snakes representing a serious risk are perceived as highly fearful. This is especially true for the vipers and allies (pit vipers) possessing a characteristic body shape with a distinct triangular head and thick body, which was found as the most fear evoking by respondents from both countries. Although the attitude toward snakes is more negative among the respondents from Azerbaijan, their fear evaluation is similar to the Czechs. For instance, despite co-habitation with the Levant viper, it was not rated by the Azerbaijanis as more fearful than other dangerous snakes. In conclusion, agreement in the evaluation of snake fear and beauty is cross-culturally high and relative fear attributed to selected snake species is not directly explainable by the current environmental and cultural differences. This may provide some support for the evolutionary hypothesis of preparedness to fear snakes. PMID:29615942

Full Text Available Intermittent hypoxia (IH during sleep is one of the major abnormalities occurring in patients suffering from obstructive sleep apnea (OSA, a highly prevalent disorder affecting 6–15% of the general population, particularly among obese people. IH has been proposed as a major determinant of oncogenetically-related processes such as tumor growth, invasion and metastasis. During the growth and expansion of tumors, fragmented DNA is released into the bloodstream and enters the circulation. Circulating tumor DNA (cirDNA conserves the genetic and epigenetic profiles from the tumor of origin and can be isolated from the plasma fraction. Here we report a microarray-based epigenetic profiling of cirDNA isolated from blood samples of mice engrafted with TC1 epithelial lung cancer cells and controls, which were exposed to IH during sleep (XenoIH group, n = 3 or control conditions, (i.e., room air (RA; XenoRA group, n = 3 conditions. To prepare the targets for microarray hybridization, we applied a previously developed method that enriches the modified fraction of the cirDNA without amplification of genomic DNA. Regions of differential cirDNA modification between the two groups were identified by hybridizing the enriched fractions for each sample to Affymetrix GeneChip Human Promoter Arrays 1.0R. Microarray raw and processed data were deposited in NCBI's Gene Expression Omnibus (GEO database (accession number: GSE61070.

Study of charm and beauty production at HERA/H1 using dilepton events

2007-04-15

A measurement is presented which investigates the production of charm and beauty quarks in ep collisions at a centre-of-mass energy of 318 GeV. Data taken by the H1 detector at the HERA collider in the years 1999, 2000, 2004 and 2005 are analysed. The collected data correspond to an integrated luminosity of 221.6 pb{sup -1}. This is the rst measurement of charm and beauty cross sections using HERA II data. Events with two or more jets of transverse momentum p{sub t}>5(4) GeV in the polar angular range 20 <{theta}<160 together with two leptons of transverse momentum p{sub t}>2(1) GeV in the polar angular ranges 30 <{theta}{sub 1}<130 and 20 <{theta}{sub 2}<150 , respectively, are selected. The first lepton is a muon, the second either a muon or an electron. Cross sections are measured in photoproduction, i.e. at photon virtualities Q{sup 2}<1 GeV{sup 2}, and for inelasticities 0.1beauty events on a statistical basis. For the first time at H1, visible charm and beauty cross sections for the production of dijet and dilepton events are determined: {sigma}(ep{yields}ec anti cX{yields}ejj{mu}eX{sup '})=4.6{+-}1.0(stat.){+-}0.5(sys.) pb, {sigma}(ep{yields}ec anti cX{yields}ejj{mu}{mu}X{sup '})=2.7 {+-}0.9(stat.){+-}0.3(sys.) pb, {sigma}(ep{yields}eb anti bX{yields}ejj{mu}eX{sup '})=9.4{+-}1.2(stat.){+-}0.9(sys.) pb, and {sigma}(ep {yields}eb anti bX{yields}ejj{mu}{mu}X{sup '})=10.4 {+-} 1.5(stat.) {+-} 1.0(sys.) pb.

Shining evolutionary light on human sleep and sleep disorders.

Sleep is essential to cognitive function and health in humans, yet the ultimate reasons for sleep-i.e. 'why' sleep evolved-remain mysterious. We integrate findings from human sleep studies, the ethnographic record, and the ecology and evolution of mammalian sleep to better understand sleep along the human lineage and in the modern world. Compared to other primates, sleep in great apes has undergone substantial evolutionary change, with all great apes building a sleeping platform or 'nest'. Further evolutionary change characterizes human sleep, with humans having the shortest sleep duration, yet the highest proportion of rapid eye movement sleep among primates. These changes likely reflect that our ancestors experienced fitness benefits from being active for a greater portion of the 24-h cycle than other primates, potentially related to advantages arising from learning, socializing and defending against predators and hostile conspecifics. Perspectives from evolutionary medicine have implications for understanding sleep disorders; we consider these perspectives in the context of insomnia, narcolepsy, seasonal affective disorder, circadian rhythm disorders and sleep apnea. We also identify how human sleep today differs from sleep through most of human evolution, and the implications of these changes for global health and health disparities. More generally, our review highlights the importance of phylogenetic comparisons in understanding human health, including well-known links between sleep, cognitive performance and health in humans. © The Author(s) 2016.

Beauty or Bane: Advancing an Aesthetic Appreciation of Wind Turbine Farms

Directory of Open Access Journals (Sweden)

Tyson-Lord J. Gray

2012-01-01

Full Text Available I begin this paper by looking at declining wind turbine sales during the years 2007 to 2010. In an attempt to locate a reason for this decline, I evaluate two claims by wind farm opponents: 1 that wind farms reduce property value, and 2 that wind farms ruin the beauty of nature. The first claim I respond to by looking at three studies conducted on residential property sales located near wind farms. For the second claim, I engage in a comparison of Immanuel Kant’s and John Dewey’s aesthetics. I ultimately advance an aesthetic appreciation of wind farms that seeks to view beauty as an integration of both emotional and cognitive perceptions.

We present calculations of the beauty photoproduction at HERA collider in the framework of the k{sub T}-factorization approach. Both direct and resolved photon contributions are taken into account. The unintegrated gluon densities in a proton and in a photon are obtained from the full CCFM, from unified BFKL-DGLAP evolution equations as well as from the Kimber-Martin-Ryskin prescription. We investigate different production rates (both inclusive and associated with hadronic jets) and compare our theoretical predictions with the recent experimental data taken by the H1 and ZEUS collaborations. Special attention is put on the x{sup obs}{sub {gamma}} variable which is sensitive to the relative contributions to the beauty production cross section. (Orig.)

To investigate the effects of 6 nights of sleep extension on sustained attention and sleep pressure before and during total sleep deprivation and after a subsequent recovery sleep. Subjects participated in two experimental conditions (randomized cross-over design): extended sleep (EXT, 9.8 ± 0.1 h (mean ± SE) time in bed) and habitual sleep (HAB, 8.2 ± 0.1 h time in bed). In each condition, subjects performed two consecutive phases: (1) 6 nights of either EXT or HAB (2) three days in-laboratory: baseline, total sleep deprivation and after 10 h of recovery sleep. Residential sleep extension and sleep performance laboratory (continuous polysomnographic recording). 14 healthy men (age range: 26-37 years). EXT vs. HAB sleep durations prior to total sleep deprivation. Total sleep time and duration of all sleep stages during the 6 nights were significantly higher in EXT than HAB. EXT improved psychomotor vigilance task performance (PVT, both fewer lapses and faster speed) and reduced sleep pressure as evidenced by longer multiple sleep latencies (MSLT) at baseline compared to HAB. EXT limited PVT lapses and the number of involuntary microsleeps during total sleep deprivation. Differences in PVT lapses and speed and MSLT at baseline were maintained after one night of recovery sleep. Six nights of extended sleep improve sustained attention and reduce sleep pressure. Sleep extension also protects against psychomotor vigilance task lapses and microsleep degradation during total sleep deprivation. These beneficial effects persist after one night of recovery sleep. © 2015 Associated Professional Sleep Societies, LLC.

Sasazawa, Y.; Kawada, T.; Kiryu, Y.

1997-08-01

This study was designed to assess the effects of daytime physical exercise on the quality of objective and subjective sleep by examining all-night sleep EEGs. The subjects were five male students, aged 19 to 20 years, who were in the habit of performing regular daytime exercise. The sleep polygraphic parameters in this study were sleep stage time as a percentage of total sleep time (%S1, %S2, %S(3+4), %SREM, %MT), time in bed (TIB), sleep time (ST), total sleep time (TST), sleep onset latency (SOL), waking from sleep, sleep efficiency, number of awakenings, number of stage shifts, number of spindles, and percentages of α and δ waves, all of which were determined by an automatic computer analysis system. The OSA questionnaire was used to investigate subjective sleep. The five scales of the OSA used were sleepiness, sleep maintenance, worry, integrated sleep feeling, and sleep initiation. Each sleep parameter was compared in the exercise and the non-exercise groups. Two-way analysis of variance was applied using subject factor and exercise factor. The main effect of the subject was significant in all parameters and the main effect of exercise in %S(3+4), SOL and sleep efficiency, among the objective sleep parameters. The main effects of the subject, except sleepiness, were significant, as was the main effect of exercise on sleep initiation, among the subjective sleep parameters. These findings suggest that daytime exercise shortened sleep latency and prolonged slow-wave sleep, and that the subjects fell asleep more easily on exercise days. There were also significant individual differences in both the objective and subjective sleep parameters.

Transcriptomic studies have shown that hundreds of genes change their expression levels across the sleep/waking cycle, and found that waking-related and sleep-related mRNAs belong to different functional categories. Proteins, however, rather than DNA or RNA, carry out most of the cellular functions, and direct measurements of protein levels and activity are required to assess the effects of behavioral states on the overall functional state of the cell. Here we used surface-enhanced laser desorption-ionization (SELDI), followed by time-of-flight mass spectrometry, to obtain a large-scale profiling of the proteins in the rat cerebral cortex whose expression is affected by sleep, spontaneous waking, short (6 hours) and long (7 days) sleep deprivation. Each of the 94 cortical samples was profiled in duplicate on 4 different ProteinChip Array surfaces using 2 different matrix molecules. Overall, 1055 protein peaks were consistently detected in cortical samples and 15 candidate biomarkers were selected for identification based on significant changes in multiple conditions (conjunction analysis): 8 "sleep" peaks, 4 "waking" peaks, and 4 "long sleep deprivation" peaks. Four candidate biomarkers were purified and positively identified. The 3353 Da candidate sleep marker was identified as the 30 amino acid C-terminal fragment of rat histone H4. This region encompasses the osteogenic growth peptide, but a possible link between sleep and this peptide remains highly speculative. Two peaks associated with short and long sleep deprivation were identified as hemoglobin alpha1/2 and beta, respectively, while another peak associated with long sleep deprivation was identified as cytochrome C. The upregulation of hemoglobins and cytochrome C may be part of a cellular stress response triggered by even short periods of sleep loss.

Beauty physics at e+ e- colliders

Beauty physics to be performed in the next decade at the resonances Y(4S) and Z 0 are compared. Large similarities are found in the physics program and the reconstruction techniques of Z 0 and asymmetric Y(4S) colliders. The physics potential of the latter is found to be superior at equal luminosity to a symmetric machine, provided a large enough boost (≥ 5). Z 0 machines will probably be the main source of the rich B S 0 physics during that period

Measurement of semi-electronic beauty-hadron decays via their impact parameter in pp collisions in ALICE

The measurement of beauty-hadron decays via the detection of electron tracks that are displaced from the primary vertex can be performed with ALICE, whose capabilities of electron identification and tracking fulfil all requirements for this task. While the large corresponding branching ratios guarantee sufficient yields of beauty-decay electrons at LHC energies, the wide electron impact parameter distribution due to the long lifetime and the decay kinematics of beauty hadrons allows for a separation of electrons from beauty-hadron decays from background electrons on a statistical basis. This thesis presents the analysis of electrons from beauty-hadron decays in protonproton collisions at centre-of-mass energies of 7 TeV and 2.76 TeV. Using the ALICE central-barrel detectors ITS, TPC, and TOF, p T -differential electron spectra are measured at mid-rapidity (vertical stroke y vertical stroke <0.8) for transverse momenta between 1 and 8 GeV/c. Information from the TPC and TOF signal is combined to select pure electron samples, whose signal-to-background ratio is subsequently enhanced via the requirement of a minimal impact parameter of the tracks towards the primary vertex in the x - y plane. Tracks from photon conversions occurring outside the innermost ITS layer, which have a wide impact parameter distribution, are rejected via the requirement of hits in both SPD layers of the ITS. The remaining hadron contamination in the selected electron track samples is determined on a statistical basis from the distributions of their energy deposition per unit of length in the TPC. A crucial challenge of this analysis is the subtraction of the electron background originating from charm decays, photon conversions, and light-meson decays from the measured inclusive electron spectrum. The corresponding electron yields are determined using spectra from PYTHIA simulations that are reweighted based on previous measurements of charmed hadrons, π 0 , and η. Minor contributions from

Neuroaesthetics has been searching for the neural bases of the subjective experience of beauty. It has been demonstrated that neural activities in the medial prefrontal cortex (mPFC) and the left primary motor cortex (lPMC) correlate with the subjective experience of beauty. Although beauty and ugliness seem to be semantically and conceptually opposite, it is still unknown whether these two evaluations represent extreme opposites in unitary or bivariate dimensions. In this study, we applied transcranial direct current stimulation (tDCS) to examine whether non-invasive brain stimulation modulates two types of esthetic evaluation; evaluating beauty and ugliness. Participants rated the subjective beauty and ugliness of abstract paintings before and after the application of tDCS. Application of cathodal tDCS over the mPFC with anode electrode over the lPMC, which induced temporal inhibition of neural excitability of the mPFC, led to a decrease in beauty ratings but not ugliness ratings. There were no changes in ratings of both beauty and ugliness when applying anodal tDCS or sham stimulation over the mPFC. Results from our experiment indicate that the mPFC and the lPMC have a causal role in generating the subjective experience of beauty, with beauty and ugliness evaluations constituting two distinct dimensions.

Unihemispheric sleep and asymmetrical sleep: behavioral, neurophysiological, and functional perspectives

Full Text Available Gian Gastone Mascetti Department of General Psychology, University of Padova, Padova, Italy Abstract: Sleep is a behavior characterized by a typical body posture, both eyes' closure, raised sensory threshold, distinctive electrographic signs, and a marked decrease of motor activity. In addition, sleep is a periodically necessary behavior and therefore, in the majority of animals, it involves the whole brain and body. However, certain marine mammals and species of birds show a different sleep behavior, in which one cerebral hemisphere sleeps while the other is awake. In dolphins, eared seals, and manatees, unihemispheric sleep allows them to have the benefits of sleep, breathing, thermoregulation, and vigilance. In birds, antipredation vigilance is the main function of unihemispheric sleep, but in domestic chicks, it is also associated with brain lateralization or dominance in the control of behavior. Compared to bihemispheric sleep, unihemispheric sleep would mean a reduction of the time spent sleeping and of the associated recovery processes. However, the behavior and health of aquatic mammals and birds does not seem at all impaired by the reduction of sleep. The neural mechanisms of unihemispheric sleep are unknown, but assuming that the neural structures involved in sleep in cetaceans, seals, and birds are similar to those of terrestrial mammals, it is suggested that they involve the interaction of structures of the hypothalamus, basal forebrain, and brain stem. The neural mechanisms promoting wakefulness dominate one side of the brain, while those promoting sleep predominates the other side. For cetaceans, unihemispheric sleep is the only way to sleep, while in seals and birds, unihemispheric sleep events are intermingled with bihemispheric and rapid eye movement sleep events. Electroencephalogram hemispheric asymmetries are also reported during bihemispheric sleep, at awakening, and at sleep onset, as well as being associated with a use

Charm and beauty quarks, produced in the early stage of heavy-ion collisions, are ideal probes to study the characteristics of the hot and dense deconfined medium (Quark-Gluon Plasma) formed in these collisions. The radiative energy loss of high energy partons interacting with the medium is expected to be larger for gluons than for quarks, and to depend on the quark mass, with beauty quarks losing less energy than charm quarks, light quarks and gluons. Therefore, a comparison of the modification in the momentum distribution or possibly in the jet shape of beauty-jets with that of light flavour or c-jets in Pb-Pb collisions relative to pp collisions allows to investigate the mass dependence of the energy loss. It also allows to study the redistribution of the lost energy and possible modifications to b-quark fragmentation in the medium. The track counting method exploits the large rφ-impact parameters, d{sub 0}, of B-meson decay products to identify beauty-jets. The signed rφ-impact parameter, d{sub 0} = sign(vector d{sub 0} . vector p{sub jet}) d{sub 0}, is calculated for each track in the jet cone, where vector d{sub 0} is pointing away from the primary vertex. The distribution of the n-th largest d{sub 0} in a jet is sensitive to the flavor of the hadronizing parton and allows to select jets coming form beauty on a statistical basis. In this contribution, we give an overview of the beauty jet measurement using the track counting method with ALICE in pp collisions at √(s) = 7 TeV that will serve as baseline reference for future energy loss studies.

The production cross section of electrons from semileptonic decays of beauty hadrons was measured at mid-rapidity (|y| < 0.8) in the transverse momentum range 1 < pt < 8 Gev/c with the ALICE experiment at the CERN LHC in pp collisions at a center of mass energy $\\sqrt{s}$ = 7 TeV using an integrated luminosity of 2.2 nb$^{-1}$. Electrons from beauty hadron decays were selected based on the displacement of the decay vertex from the collision vertex. A perturbative QCD calculation agrees with the measurement within uncertainties. The data were extrapolated to the full phase space to determine the total cross section for the production of beauty quark-antiquark pairs.

Beauty and ugliness in the bodies and faces of others: an fMRI study of person esthetic judgement.

Science.gov (United States)

Martín-Loeches, M; Hernández-Tamames, J A; Martín, A; Urrutia, M

2014-09-26

Whether beauty and ugliness represent two independent judgement categories or, instead, opposite extremes of a single dimension is a matter of debate. In the present 3T-functional Magnetic Resonance Imaging (fMRI) study, 20 participants were scanned while judging faces and nude bodies of people classified as extremely ugly, extremely beautiful, or indifferent. Certain areas, such as the caudate/nucleus accumbens (NAcc) and the anterior cingulate cortex (ACC), exhibited a linear relationship across esthetic judgments supporting ugliness as the lowest extreme of a beauty continuum. Other regions, such as basal occipital areas, displayed an inverse pattern, with the highest activations for ugly and the lowest for beautiful ones. Further, several areas were involved alike by both the very beautiful and the very ugly stimuli. Among these, the medial orbitofrontal cortex (mOFC), as well as the posterior and medial portions of the cingulate gyrus. This is interpreted as the activation of neural circuits related to self- vs. other-assessment. Beauty and ugliness in the brain, at least in relation to natural and biologically and socially relevant stimuli (faces and bodies), appear tightly related and non-independent. Finally, neutral stimuli elicited strong and wide activations of the somatosensory and somatomotor systems together with longer reaction times and higher error rates, probably reflecting the difficulty of the human brain to classify someone as indifferent.

Unihemispheric sleep and asymmetrical sleep: behavioral, neurophysiological, and functional perspectives.

Science.gov (United States)

Mascetti, Gian Gastone

2016-01-01

Sleep is a behavior characterized by a typical body posture, both eyes' closure, raised sensory threshold, distinctive electrographic signs, and a marked decrease of motor activity. In addition, sleep is a periodically necessary behavior and therefore, in the majority of animals, it involves the whole brain and body. However, certain marine mammals and species of birds show a different sleep behavior, in which one cerebral hemisphere sleeps while the other is awake. In dolphins, eared seals, and manatees, unihemispheric sleep allows them to have the benefits of sleep, breathing, thermoregulation, and vigilance. In birds, antipredation vigilance is the main function of unihemispheric sleep, but in domestic chicks, it is also associated with brain lateralization or dominance in the control of behavior. Compared to bihemispheric sleep, unihemispheric sleep would mean a reduction of the time spent sleeping and of the associated recovery processes. However, the behavior and health of aquatic mammals and birds does not seem at all impaired by the reduction of sleep. The neural mechanisms of unihemispheric sleep are unknown, but assuming that the neural structures involved in sleep in cetaceans, seals, and birds are similar to those of terrestrial mammals, it is suggested that they involve the interaction of structures of the hypothalamus, basal forebrain, and brain stem. The neural mechanisms promoting wakefulness dominate one side of the brain, while those promoting sleep predominates the other side. For cetaceans, unihemispheric sleep is the only way to sleep, while in seals and birds, unihemispheric sleep events are intermingled with bihemispheric and rapid eye movement sleep events. Electroencephalogram hemispheric asymmetries are also reported during bihemispheric sleep, at awakening, and at sleep onset, as well as being associated with a use-dependent process (local sleep).

Short-term sleep deprivation leads to decreased systemic redox metabolites and altered epigenetic status.

Sleep is critical for repair as well as the rejuvenation processes in the body and many of these functions are regulated via underlying cellular metabolic homeostasis. Changes in sleep pattern are reported to alter such metabolic function resulting in altered disease susceptibility or behavior. Here, we measured the extent to which overnight total sleep deprivation (SD) in young adult humans can influence systemic (plasma-derived) redox-metabolism including the major antioxidant, glutathione as well as DNA methylation levels. Nineteen participants (n = 19, μ age = 21, SD = 3.09) underwent morning testing before and after overnight total SD. Biochemical measures before and after SD revealed that glutathione, ATP, cysteine, and homocysteine levels were significantly reduced following one night of sleep deprivation (all p's sleep deprivation (maintaining wakefulness) uses up metabolic reserves, we observed that morning cortisol levels were blunted after sleep deprivation. There were no significant correlations between self-reported or actigraphy-measured sleep and the biochemical measurements, strongly indicating that prior sleep behavior did not have any direct influence on the biochemical measures taken at baseline or after sleep deprivation. Results from the current investigation supports the previous literature implicating the induction of oxidative stress and ATP depletion with sleep deprivation. Furthermore, such altered antioxidant status can also induce downstream epigenetic changes. Although we did not measure the specific genes that were altered under the influence of such sleep deprivation, such epigenetic changes could potentially contribute towards disease predisposition.

Sleep Deficiency and Sleep Health Problems in Chinese Adolescents

Full Text Available A survey of sleep schedules, sleep health, and the impact on school performance was conducted in 585 adolescents in a high school in China. A high level of early and circadian-disadvantaged sleep/wake schedules during weekdays was observed. Significantly shorter sleep duration on weekdays was reported ( P < 0.0001. Older teenagers slept significantly less than the younger teenagers ( P < 0.0001. Complaints of inadequate sleep and sleepiness during weekdays were prevalent. Night awakenings were reported in 32.2% of students. Students with a sleep length of less than 7 hours, complaint of inadequate sleep, or excessive daytime sleepiness during weekdays were more likely to report an adverse effect of poor sleep on performance. The present observations are qualitatively similar to those reported in our study in American adolescents, particularly with respect to Chinese adolescents exhibiting a similar sleep deficiency on weekdays. We concluded that sleep deficiency and sleep health problems were prevalent in the participating adolescents in China, and were perceived to adversely affect school performance.

Aging induced ER stress alters sleep and sleep homeostasis

Alterations in the quality, quantity and architecture of baseline and recovery sleep have been shown to occur during aging. Sleep deprivation induces endoplasmic reticular (ER) stress and upregulates a protective signaling pathway termed the unfolded protein response (UPR). The effectiveness of the adaptive UPR is diminished by age. Previously, we showed that endogenous chaperone levels altered recovery sleep in Drosophila melanogaster. We now report that acute administration of the chemical chaperone sodium 4-phenylbutyrate (PBA) reduces ER stress and ameliorates age-associated sleep changes in Drosophila. PBA consolidates both baseline and recovery sleep in aging flies. The behavioral modifications of PBA are linked to its suppression of ER stress. PBA decreased splicing of x-box binding protein 1 (XBP1) and upregulation of phosphorylated elongation initiation factor 2 α (p-eIF2α), in flies that were subjected to sleep deprivation. We also demonstrate that directly activating ER stress in young flies fragments baseline sleep and alters recovery sleep. Alleviating prolonged/sustained ER stress during aging contributes to sleep consolidation and improves recovery sleep/ sleep debt discharge. PMID:24444805

Preasymptotic (in the heavy quark mass) corrections in the non-leptonic decay rates of beautiful mesons and baryons are considered. The effects of real and virtual gluon emission are taken into account. Main emphasis is put on the difference of the life-times of B s 0 mesons with different CP parity. This difference is found to be the largest in the b-family. Possibilities for experimental study of this phenomenon are briefly discussed

Beauty-conserving strangeness-changing rare semileptonic decays of Bs meson

International Nuclear Information System (INIS)

Harpreet Kaur

1999-01-01

The beauty-conserving strangeness-changing decays of B s meson are examined. In the charm sector, charm-conserving strangeness changing (Δc = 0, Δs ≠ 0) decays are Cabibbo suppressed and are governed by the CKM element V us which is much smaller than the CKM diagonal element V cs , so may be of little interest. On the other hand, in the b-sector, beauty-conserving strangeness changing (Δb = 0, Δs ≠ 0) decays are CKM allowed as the CKM matrix element V us governing such decays is much larger than V bc or V bu which govern respectively the b→c or b→u transitions. The phase space available, however, is too small for the decays considered here. The numerical estimates for the decay widths of two such modes of B s meson are presented. (author)

‘For me… it’s a miracle’: injecting beauty among kathoeis in a provincial Thai city

Science.gov (United States)

Poompruek, Panoopat; Boonmongkon, Pimpawun; Guadamuz, Thomas E.

2014-01-01

Background The Thai term kathoei refers to non-gender-normative females, males and intersexual individuals at different stages of the transitional spectrum with recognized social and cultural roles in society. Nevertheless, kathoeis are only tolerated in Thai society. Many kathoeis seek social acceptance through beauty and turn to the off-label injection of various ‘beauty drugs’. Methods The first author conducted an ethnographic study of injection parties at a wedding studio in a Central Thai provincial city between April and September 2011. Data were gathered through participant observation, focus group discussions and narrative interviews with six participants. All data were collected and analyzed in Thai, and later translated. Findings While injection parties provide opportunities for kathoeis to socialize, bond, and share experiential knowledge on chemically-assisted transformation, they also reproduce ideologies of gender, beauty and sexuality that reinforce the notion that if a kathoei is to maintain her beauty, she must use medicines more frequently and in higher doses. Conclusion Injection parties among Thai kathoeis feature drug use that is entirely reasonable in terms of their own lay knowledge. Empowering kathoeis, by providing accessible information on chemicals and health in a way that reflects the complexity and diversity of their practices, would be one way to reduce health risks. Society must give more long-term options to kathoeis to build their sense of self, based on things besides being beautiful. PMID:25047007

Women's attitudes to beauty, aging, and the place of cosmetic procedures: insights from the QUEST Observatory.

2016-03-01

The quest for beauty has been a constant theme in human history since the earliest civilizations. The QUEST Observatory, an online observational study, investigated how women continue the pursuit of beauty in the 21st century by examining women's perceptions of facial attractiveness and the strategies they adopt to combat the effects of time on their faces. To investigate women's attitudes toward beauty, aging, and the place of minimally invasive cosmetic procedures and anti-aging skincare. An in-depth questionnaire was developed by experts in dermatology, esthetic medicine, and social anthropology as the basis for this online, observational study. A nationally representative sample of 1000 French women aged between 25 and 70 years took part in the study. The main criteria for beauty were identified as a natural look, self-confidence, and attractive skin. A woman is considered to be at the peak of beauty in her mid-thirties just before early signs of facial aging begin to appear. Approximately 50% of women contemplate cosmetic procedures, but less than 10% go ahead. Confidence in the practitioner and good postprocedure follow-up are as influential as efficacy, safety, and cost in decisions about cosmetic procedures. The QUEST Observatory sheds valuable light on factors that affect women's choices regarding strategies for anti-aging and cosmetic procedures. These findings will help esthetic practitioners to better understand their patients and to meet their expectations. © 2015 Wiley Periodicals, Inc.
