The aim of this paper is to develop a database to determine a new biomorphometric standard of attractiveness. Sampling was carried out using noninvasive three-dimensional relief methods to measure the soft tissues of the face. These anthropometric measurements were analyzed to verify the existence of any canons with respect to shape, size, and measurement proportions which proved to be significant with regard to the aesthetics of the face. Finally, the anthropometric parameters obtained were compared with findings described in the international literature...

Science is our best current approximation of the way things work. You cannot do science unless you believe there is a discernable truth inherent to the arrangement of our tangible world. The problem is, we in our given time never know where exactly the asymptote lies or how far we are from it. My curiosity about the natural world is innate, but fate has variously gifted me with outstanding personal opportunities to indulge that curiosity through the study of viruses. To a woman of the boomer generation, professional paths were not always open-door, and to a certain extent they still aren't...

Gene therapy protocols require robust and long-term gene expression. For two decades, retrovirus family vectors have offered several attractive properties as stable gene-delivery vehicles. These vectors represent a technology with widespread use in basic biology and translational studies that require persistent gene expression for treatment of several monogenic diseases. Immunogenicity and insertional mutagenesis represent the main obstacles to a wider clinical use of these vectors. Efficient and safe non-viral vectors are emerging as a promising alternative and facilitate clinical gene therapy studies...

This is a letter to a young friend who has become a paediatrician. It is a senior paediatrician, trying to transmit something useful, that writes it. The lives of those who care are made of many human relationships, a lot of reading, more different interpretations of these relationships and these readings. Each of us will build over the years their ethical model, their ability to discuss new problems and new cases with colleagues, their ability to critically analyse the scientific literature as well as the willingness to listen to patients and families...

BACKGROUND: While spirituality is well described in end-of-life care literature, research on its place in the delivery room remains largely limited to mother-oriented qualitative studies focusing on life-threatening situations (e.g., high-risk pregnancies). Our aim was to compare mothers' and fathers' spirituality during childbirth. METHODS: A mixed methods questionnaire was developed from our childbirth-related spirituality categorization and distributed to all parents of newborns, 12-24 h postpartum, over 45 consecutive days...

Two major mechanisms of aesthetic evolution have been suggested. One focuses on naturally selected preferences (Evolutionary Aesthetics), while the other describes a process of evaluative coevolution whereby preferences coevolve with signals. Signaling theory suggests that expertise moderates these mechanisms. In this article we set out to verify this hypothesis in the domain of art and use it to elucidate Western modern art's deviation from naturally selected preferences. We argue that this deviation is consistent with a Coevolutionary Aesthetics mechanism driven by prestige-biased social learning among art experts...

Differences between norm ratings collected when participants are asked to consider more than one picture characteristic are contrasted with the traditional methodological approaches of collecting ratings separately for image constructs. We present data that suggest that reporting normative data, based on methodological procedures that ask participants to consider multiple image constructs simultaneously, could potentially confounded norm data. We provide data for two new image constructs, beauty and the extent to which participants encountered the stimuli in their everyday lives...

We showed that the looking time spent on faces is a valid covariate of beauty by testing the relation between facial attractiveness and gaze behavior. We presented natural scenes which always pictured two people, encompassing a wide range of facial attractiveness. Employing measurements of eye movements in a free viewing paradigm, we found a linear relation between facial attractiveness and gaze behavior: The more attractive the face, the longer and the more often it was looked at. In line with evolutionary approaches, the positive relation was particularly pronounced when participants viewed other sex faces...

Sleeping Beauty (SB) is the first synthetic DNA transposon that was shown to be active in a wide variety of species. Here, we review studies from the last two decades addressing both basic biology and applications of this transposon. We discuss how host-transposon interaction modulates transposition at different steps of the transposition reaction. We also discuss how the transposon was translated for gene delivery and gene discovery purposes. We critically review the system in clinical, pre-clinical and non-clinical settings as a non-viral gene delivery tool in comparison with viral technologies...

We describe the generation of a set of plasmid vector tools that allow the rapid generation of complex-interacting stable transgenes in immortalized and primary cells. Of particular importance is inclusion of a mechanism to monitor the activation status of regulatory pathways via a reporter cassette (using Gaussia Luciferase), with control of additional transgene expression through doxycycline de-repression. The resulting vectors can be used to assess regulatory pathway activation and are well suited for regulatory pathway crosstalk studies...

BACKGROUND: Injection of botulinum toxin type A for cosmetic purposes is common. It is believed to be safe, but adverse reactions have been reported, including dysphagia, generalized paralysis, respiratory depression, and death caused by focal injection of the toxin. Early administration of antitoxin in patients with adverse reactions is the mainstay of management, but the time window for its clinical efficacy is not well defined. CASE REPORTS: Two female adult patients with clinical botulism after botulinum toxin type A injection are described...

The aesthetic value of landscapes contributes to human well-being. However, studies which have investigated the link between biodiversity and ecosystem services have not taken aesthetic value into account. In this study we evaluated how the aesthetics of coralligenous reefs, a key marine ecosystem in the Mediterranean, is perceived by the general public and how aesthetic preferences are related to biodiversity facets (taxonomic, phylogenetic and functional diversities). We performed both biodiversity measures and online-surveys of aesthetic perception on photographic quadrats sampled along the French Mediterranean coast...

BACKGROUND: Perception of beauty is influenced by the individual's geographic, ethnic, cultural, and demographic background. However, objective measurements remain the foundation for aesthetic evaluations. In the quest for to better define "ideal" lip characteristics, this study assumes interdependence between variables such as country of residence, sex, age, occupation, and aesthetic perception. OBJECTIVES: This study will increase surgeons' awareness with respect to different lip size preferences...

Anton van Leeuwenhoek's startling microscopic observations in the 1600s first stimulated fascination with the way that cells use cilia to generate currents and to swim in a fluid environment. Research in recent decades has yielded deep knowledge about the mechanical and biochemical nature of these organelles but only opened a greater fascination about how such beautifully intricate and multifunctional structures arose during evolution. Answers to this evolutionary puzzle are not only sought to satisfy basic curiosity, but also, as stated so eloquently by Dobzhansky (Am Zool 4: 443 [1964]), because "nothing in biology makes sense except in the light of evolution...

In dance, the goals of actions are not always clearly defined. Investigations into the perceived quality of dance actions and their relation to biomechanical motion should give insight into the performance of dance actions and their goals. The purpose of this review was to explore and document current literature concerning dance perception and its relation to the biomechanics of motion. Seven studies were included in the review. The study results showed systematic differences between expert, non-expert, and novice dancers in biomechanical and perceptual measures, both of which also varied according to the actions expressed in dance...

Facial attractiveness plays a significant role in social interactions and the effect of beauty premium is frequently observed. Previous studies showed that observing attractive counterparts would alleviate one's sense of unfairness. However, the mechanism underlying this phenomenon remained to be clarified. In this study, male participants were engaged in a modified Dictator game as recipients and their electroencephalograms were recorded. They were convinced that anonymous females who vary in facial attractiveness played as dictators...
