Identification and analysis of functional elements in 1% of the human genome by the ENCODE pilot project.

We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap one another. Second, systematic examination of transcriptional regulation has yielded new understanding about transcription start sites, including their relationship to specific regulatory sequences and features of chromatin accessibility and histone modification. Third, a more sophisticated view of chromatin structure has emerged, including its inter-relationship with DNA replication and transcriptional regulation. Finally, integration of these new sources of information, in particular with respect to mammalian evolution based on inter- and intra-species sequence comparisons, has yielded new mechanistic and evolutionary insights concerning the functional landscape of the human genome. Together, these studies are defining a path for pursuit of a more comprehensive characterization of human genome function.

Hyperventilation in anticipatory music performance anxiety

Objectives and Methods: Self-report studies have shown an association between music performance anxiety (MPA) and hyperventilation complaints. However, hyperventilation was never assessed physiologically in MPA. This study investigated the self-reported affective experience, self-reported physiological symptoms, and cardiorespiratory variables including partial pressure of end-tidal CO(2) (Petco(2)), which is an indicator for hyperventilation, in 67 music students before a private and a public performance. The response coherence between these response domains was also investigated.ResultsFrom the private to the public session, the intensity of all self-report variables increased (all p values < .001). As predicted, the higher the musician's usual MPA level, the larger were these increases (p values < .10). With the exception of Petco(2), the main cardiorespiratory variables also increased from the private to the public session (p values < .05). These increases were not modulated by the usual MPA level (p values > .10). Petco(2) showed a unique response pattern reflected by an MPA-by-session interaction (p < .01): it increased from the private to the public session for musicians with low MPA levels and decreased for musicians with high MPA levels. Self-reported physiological symptoms were related to the self-reported affective experience (p values < .05) rather than to physiological measures (p values > .17).ConclusionsThese findings show for the first time how respiration is stimulated before a public performance in music students with different MPA levels. The hypothesis of a hyperventilation tendency in high-performance-anxious musicians is supported. The response coherence between physiological symptoms and physiological activation is weak.

A l'origine fut la lettre...

Les premiers chrétiens ont sans doute rassemblé assez tôt, dès les années 40, des collections de paroles de Jésus, des séries de paraboles, des cycles de miracles. Les premiers documents achevés qu'ils ont produits sont toutefois des lettres, avant que n'apparaisse le premier évangile, celui de Marc, juste avant 70. À l'origine du christianisme fut la lettre.

Actes d'apôtres

(Résumé de l'ouvrage) Cette nouvelle traduction de la Bible est la première traduction française de la Bible réalisée en commun par des spécialistes des langues et des textes bibliques et des écrivains. Entièrement originale, elle a été élaborée d'après les langues sources de la Bible (Hébreu, Araméen, Grec), et selon les dernières éditions critiques. Chaque livre biblique a été confié à un tandem composé d'un bibliste et d'un écrivain, qui ont travaillé au coude à coude pendant 6 ans. Une idée forte a prévalu : jouer sur la pluralité des genres, des écritures, des interprétations, aboutissant à une Bible à plusieurs voix, qui transmet dans la langue et les littératures françaises contemporaines la diversité des genres littéraires, des styles, des formes, des auteurs, des inspirations, des traditions... Cette nouvelle traduction est le fruit d'une collaboration internationale exceptionnelle entre 20 écrivains et poètes contemporains francophones (parmi lesquels François Bon, Emmanuel Carrère, Florence Delay, Jean Echenoz, Jacques Roubaud...) et 27 spécialistes de la Bible et des langues anciennes. « Bible d'une nouvelle génération », cette Bible renoue avec l'histoire de notre culture. Elle affirme que cette histoire n'est pas close, que la Bible garde l'étonnante capacité de solliciter et de provoquer.

L'adresse à Jésus dans les évangiles synoptiques

A number of persons in the Gospels address Jesus by a title, e.g., 'teacher', sir', master', when they speak to him. In parallel episodes in the synoptic Gospels these titles undergo variations. This article present a complete comparative study of the titles addressed to Jesus in Mathew, Mark and Luke and finishes with a description of the titles proper to each Gospel.

Acknowledgment and psychiatric symptoms in police officers in Switzerland

The way supervisors acknowledge specific contribution and efforts of their employees has an impact on occupational health and wellbeing. Acknowledgement is a protective factor when it is sufficiently provided. We carried out a study about occupational health in police officers with special emphasis on acknowledgment and reward. A questionnaire was sent to 1000 police officers and inspectors working for a cantonal administration in Switzerland. In total, 695 participants answered the questionnaire. We used the TST questionnaire (French version of the Langner's questionnaire on psychiatric symptoms) to identify cases characterized by potential mental health problems. Multiple choice items (5 modalities ranging from "not at all" to "tremendously") were used to measure acknowledgment. The score for psychiatric symptoms was high (TST score >or= 9) for 86 police officers and inspectors for whom health might be at risk. Compared with police officers having low or medium scores for psychiatric symptoms (TST score < 9), police officers with high TST scores were more likely to report the lack of support and attention from the supervisors (odds ratio [OR] 3.2, 95% confidence interval [CI] 2.0 to 5.1) and the lack of acknowledgment by the hierarchy (OR 3.0, 95% CI 1.9 to 4.8). They were also more likely to mention that judicial authorities have a low consideration for police officers (OR 2.7, 95% CI 1.7 to 4.3) and that the public in general have a low appreciation of police officers (OR 1.8, 95% CI 1.2 to 2.9). Preserving mental health in occupations characterized by high emotional demand is challenging. Our results show that acknowledgment and mental health are associated. Further research should address a potential causal relation of acknowledgment on mental health in police officers and inspectors.

The effects of nutrition, puberty and dancing on bone density in adolescent ballet dancers.

Ballet dancers have on average a low bone mineral content (BMC), with elevated fracture-risk, low body mass index (BMI) for age (body mass index, kg/m2), low energy intake, and delayed puberty. This study aims at a better understanding of the interactions of these factors, especially with regard to nutrition. During a competition for pre-professional dancers we examined 127 female participants (60 Asians, 67 Caucasians). They averaged 16.7 years of age, started dancing at 5.8 years, and danced 22 hours/week. Assessments were made for BMI, BMC (DXA), and bone mineral apparent density (BMAD) at the lumbar spine and femoral neck, pubertal stage (Tanner score), and nutritional status (EAT-40 questionnaire and a qualitative three-day dietary record). BMI for age was found to be normal in only 42.5% of the dancers, while 15.7% had a more or less severe degree of thinness (12.6% Grade2 and 3.1% Grade 3 thinness). Menarche was late (13.9 years, range 11 to 16.8 years). Food intake, evaluated by number of consumed food portions, was below the recommendations for a normally active population in all food groups except animal proteins, where the intake was more than twice the recommended amount. In this population, with low BMI and intense exercise, BMC was low and associated with nutritional factors; dairy products had a positive and non-dairy proteins a negative influence. A positive correlation between BMAD and years since menarche confirmed the importance of exposure to estrogens and the negative impact of delayed puberty. Because of this and the probable negative influence of a high intake of non-dairy proteins, such as meat, fish, and eggs, and the positive association with a high dairy intake, ballet schools should promote balanced diets and normal weight and should recognize and help dancers avoid eating disorders and delayed puberty caused by extensive dancing and inadequate nutrition.

Diagnostic value of lipopolysaccharide-binding protein and procalcitonin for sepsis diagnosis in forensic pathology.

The aims of this study were twofold. The first was to investigate the diagnostic performance of two biochemical markers, procalcitonin (PCT) and lipopolysaccharide-binding protein (LBP), considering each individually and then combined, for the postmortem diagnosis of sepsis. We also tested the usefulness of pericardial fluid for postmortem LBP determination. Two study groups were formed, a sepsis-related fatalities group of 12 cases and a control group of 30 cases. Postmortem native CT scans, autopsy, histology, neuropathology, and toxicology as well as other postmortem biochemical investigations were performed in all cases. Microbiological investigations were also carried out in the septic group. Postmortem serum PCT and LBP levels differed between the two groups. Both biomarkers, individually considered, allowed septic states to be diagnosed, whereas increases in both postmortem serum PCT and LBP levels were only observed in cases of sepsis. Similarly, normal PCT and LBP values in postmortem serum were identified only in non-septic cases. Pericardial fluid LBP levels do not correlate with the presence of underlying septic states. No relationship was observed between postmortem serum and pericardial fluid LBP levels in either septic or non-septic groups, or between pericardial fluid PCT and LBP levels.
