Seán M Stewart
Small drops of liquid brought into contact with very hot surfaces float above it as beautiful, slightly flattened spheroids without coming to the boil. An example of film boiling, drops that are sessile can often suddenly and quite unexpectedly start to oscillate forming highly symmetric patterns of surprising pulchritude. The rim of these oscillating drops take on "star-shaped" patterns with many different modes of vibration possible. Still an object of study today, their discovery, early accounts, rediscovery and ensuing controversies over claims of priority, before quietly slipping away from the collective memory of the scientific community to become all but forgotten makes for a compelling story in the early history of film boiling...

INTRODUCTION: Norms and patterns of nasal esthetics are essential for an adequate preoperative evaluation and surgical programming. The esthetic nasal patterns used are a blend of artistic beauty ideals and tracings in models and celebrities. Because they do not consider population measures, they vary according to the period, and allow a discrepancy between the surgeon's preference and the patient's real desire for rhinoplasty. Not all populations wish to obtain an esthetic result according to these values, but prefer a natural result, that is, one with some of the nasal characteristics of the population to which they belong to...

Although genomic sequencing has provided a better understating of the genetic landmarks in triple-negative breast cancer (TNBC), functional validation of candidate cancer genes (CCG) remains unsolved. In this study, we used a transposon mutagenesis strategy based on a two-step Sleeping Beauty (SB) forward genetic screen to identify and validate new tumor suppressors (TS) in this disease. We generated 120 siRNAs targeting 40 SB-identified candidate breast cancer TS genes and used them to downregulate expression of these genes in four human TNBC cell lines...

INTRODUCTION: There are discrepancies between the public's current beauty desires and conventional theories and historical rules regarding facial beauty. This photogrammetric study aims to describe in detail mathematical differences in facial configuration between attractive Caucasian and attractive Asian faces. METHODS: To analyse the structural differences between attractive Caucasian and attractive Asian faces, frontal face and lateral face views for each race were morphed; facial landmarks were defined, and the relative photographic pixel distances and angles were measured...

During my sabbatical, I rode my bike 3300 miles from Washington, DC, to Seattle, WA, in order to engage in dialog with people along the northern tier of America's heartland. Through informal and candid conversations with >100 people, I gained insights into attitudes and opinions about the Patient Protection and Affordable Care Act (Obamacare). The comments were overwhelmingly negative. In this reflective essay, I share some of the conversations I had and the insights I gained from this remarkable journey across our beautiful country...

PURPOSE: In contrast to art-therapy, little is known about the role of art-making for people who have been diagnosed with cancer, and even less is known about program-based art-making. This study explored the experience of participation in a visual art-making program for people during and after cancer treatment in the Northern Territory of Australia. METHOD: A longitudinal, qualitative, single cohort study was undertaken. Eight women diagnosed with breast and/or ovarian cancer participated in weekly art-making sessions over eight weeks, facilitated by two professional artists...

Explicit negative attitudes towards obese individuals are well documented and seem to modulate the activity of perceptual areas, such as the Extrastriate Body Area (EBA) in the lateral occipito-temporal cortex, which is critical for body-shape perception. Nevertheless, it is still unclear whether EBA serves a role in implicit weight-stereotypical bias, thus reflecting stereotypical trait attribution on the basis of perceptual cues. Here, we used an Implicit Association Test (IAT) to investigate whether applying transcranial direct current stimulation (tDCS) over bilateral extrastriate visual cortex reduces pre-existing implicit weight stereotypical associations (i...

BACKGROUND: 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...

Using synthetic polypeptides as a model system, the theories of helix-coil transition were developed into one of the most beautiful and fruitful subjects in macromolecular science. The classic models proposed by Schellman and Zimm-Bragg more than 50 years ago, differ in the assumption on whether the configuration of multiple helical sequences separated by random coil sections is allowed in a longer polypeptide chain. Zimm also calculated the critical chain lengths that facilitate such interrupted helices in different solvent conditions...

Smile is an expression of happiness, self-confidence, kindness and beauty. Along with teeth and lips, gingiva is also a vital component of smile. Melanin induced gingival hyper pigmentation may appear un-aesthetic especially when it is associated with high smile line, upper anterior labial segment and is uneven in appearance. It affects individuals from all races. Generally, it is believed that melanin induced gingival hyper pigmentation is confined to individuals from dark races. But studies have shown that Iranian, Indian, Italian, Arabian, Greek...

An open-label, randomized, multi-centre trial was conducted to compare the immunogenicity and safety of an indigenously developed tetravalent DTwP-Hib vaccine, Easyfour®-TT with a commercially available vaccine, Quadrovax®. A total of 244 infants in good health, aged 6-10 weeks, were randomised in a 1:1 allocation to receive three doses of the test or comparator vaccine. Immunogenicity of the vaccines was determined by measuring the baseline and post-vaccination antibody response against the vaccine antigens; safety was evaluated in terms of local and systemic reactions (solicited and unsolicited) reported during the trial...

Coral snake envenomations are well characterized to be lethally neurotoxic. Despite this, few multispecies, neurotoxicity and antivenom efficacy comparisons have been undertaken and only for the Micrurus genus; Micruroides has remained entirely uninvestigated. As the USA's supplier of antivenom has currently stopped production, alternative sources need to be explored. The Mexican manufacturer Bioclon uses species genetically related to USA species, thus we investigated the efficacy against Micrurus fulvius (eastern coral snake), the main species responsible for lethal envenomations in the USA as well as additional species from the Americas...

INTRODUCTION: In 2009, ultraviolet-emitting tanning devices, i.e. sunbeds and tanning booths, were officially classified as carcinogenic to human health (Group 1) by the International Agency for Research on Cancer. METHODS: Here, we aim to estimate South African-based facilities with indoor tanning services advertised in the printed Yellow Pages and online in two directories. Printed Yellow Pages telephone directory beauty salon facilities listings (2010-14) for all provinces were examined and those mentioning "sunbed" and/or "tanning bed" recorded...

BACKGROUND: As interest in skin beauty increases, the development of new skin whitening agents has attracted substantial attention; however, the action mechanism of the agents developed so far remains largely unknown. Tranexamic acid (TXA) is commonly being used to reduce melanin synthesis in patients with melasma and also used as a raw material for functional whitening cosmetics, although its action mechanism is poorly understood. Autophagy has been well known to be essential for tissue homeostasis, adaptation to starvation, and removal of dysfunctional organelles or pathogens...

There is an urgent need to quantify the impacts of artisanal fisheries and define management practices that allow for the recovery and conservation of exploited stocks. The extent of illegal catch is particularly critical as a driver of overexploitation in artisanal fisheries. However, the lack of data at proper spatial scales limits the evaluation of illegal fishing and effectiveness of management practices. We used a catch curve analysis to estimate total instantaneous mortality as a proxy of fishing pressure in the artisanal benthic fishery in central Chile...

Nature creates beautiful structural colors, and some of these colors are produced by nanostructural arrays of melanin. Polydopamine (PDA), an artificial black polymer produced by self-oxidative polymerization of dopamine, has attracted extensive attention because of its unique properties. PDA is a melanin-like material, and recent studies have reported that photonic materials based on PDA particles showed structural colors by enhancing color saturation through the absorption of scattered light. Herein, we describe the preparation of three-dimensional (3D) colloidal photonic materials, such as structural color balls and fibers, from biomimetic core-shell particles with melanin-like PDA shell layers...

Ivabradine is an original drug that has been approved in two indications (systolic heart failure and angina). The aim of this short review is to draw the attention of clinician prescribers to the evidence base of ivabradine. Three large randomized trials testing ivabradine versus placebo have been performed. The BEAUTIFUL and SIGNIFY trials were in fact negative in the treatment of angina while the SHIFT trial found a marginal benefit of ivabradine over placebo in the treatment of heart failure. These important results are put into perspective in order to improve the assessment of risk-cost/benefit balances when ivabradine is considered...
