Colour is one of the most important appearance attributes in a variety of fields including both science and industry. The focus of this work is on cosmetics field and specifically on the performance of the human visual system on the selection of foundation makeup colour that best matches with the human skin colour. In many cases, colour evaluations tend to be subjective and vary from person to person thereby producing challenging problems to quantify colour for objective evaluations and measurements. Although many researches have been done on colour quantification in last few decades, to the best of our knowledge, this is the first study to evaluate objectively a consumer's visual system in skin colour matching through a psychophysical experiment under different illuminations exploiting spectral measurements. In this paper, the experiment setup is discussed and the results from the experiment are presented. The correlation between observers' skin colour evaluations by using PANTONE Skin Tone Guide samples and spectroradiometer is assessed. Moreover, inter and intra observer variability are considered and commented. The results reveal differences between nine ethnic groups, between two genders, and between the measurements under two illuminants (i.e.D65 and F (fluorescent)). The results further show that skin colour assessment was done better under D65 than under F illuminant. The human visual system was three times worse than instrument in colour matching in terms of colour difference between skin and PANTONE Skin Tone Guide samples. The observers tend to choose lighter, less reddish, and consequently paler colours as the best match to their skin colour. These results have practical applications. They can be used to design, for example, an application for foundation colour selection based on correlation between colour measurements and human visual system based subjective evaluations.

Abstract Background/Aims  The lack of objective outcome measures for Raynaud's phenomenon (RP) has been a major limiting factor in development of effective treatments. At present, the Raynaud's Condition Score (RCS) is the only validated outcome measure, and is highly subjective. Mobile phone technology could provide a way forward. We have developed a smartphone app for RP monitoring that guides the patient through the process of capturing images of their hands during RP episodes, as well as capturing other data through post-attack and daily questionnaires. One of the objectives of our research programme (reported here) was to compare digital image (photographic) parameters to the RCS. Methods  40 patients with RP (8 with primary RP, 32 with RP secondary to systemic sclerosis) were recruited (40 female, median age (range): 57 years (25-74), median (range) duration of RP symptoms: 17 (0-53) years). Patients were given a smartphone handset with a pre-installed Raynaud’s Monitoring app and were trained on how to use it/take usable photographs. They were then asked to take photographs of RP attacks over a 14 day period and also to record the RCS for each episode. The app specifically prompts the patient to take a picture of their hand every minute during an attack, until confirmation is given that the attack is complete. At a 2nd visit, the handsets, images, and data were collected for analysis. The mean colour change during each RP attack was quantified (semi-automated method) by the Bhattacharyya distance (BD) in colour space between a region of interest (e.g. a section of a digit) and a control region (dorsal hand). BD was then compared to the RCS using ANOVA, after controlling for patient variability in the range of RCS values used by each patient. Results  A total of 3,030 images were collected, describing 229 RP attacks. The median RCS reported was 6 (inter-quartile range [IQR]: 4), while the median for BD was 5.6 (IQR 3.2). ANOVA showed that measured values of the mean image BD were significantly different when different values of RCS were recorded by the patient (p < 0.001), i.e. attacks where patients selected different values of RCS had significantly different values of BD. Across all attacks/patients the F-value from ANOVA for RCS was 76.2, suggesting that the variation in BD for different values of RCS is much greater than the variation in BD for any one value of RCS. Conclusion  Patients successfully used a smartphone app to collect photographs and data during episodes of RP. A strong association was found between skin colour change (via BD) and the gold-standard RCS. Mobile phone-documented colour change therefore has potential as an objective measure of RP. Further validation work is now required, as well as studies examining sensitivity to change. Disclosure  G. Dinsdale: None. J. Manning: None. A. Herrick: None. M. Dickinson: None. C. Taylor: None.

Apricot (Prunus armeniaca L.) is an economically important tree species globally cultivated in temperate areas. Italy has an ample number of traditional varieties, but numerous landraces are abandoned and at risk of extinction because of increasing urbanization, agricultural intensification, and varietal renewal. In this work, we investigated the morphological and genetic diversity present in an ex-situ collection of 28 neglected varieties belonging to the so-called “Vesuvian apricot”. Our aim was to understand the level of diversity and the possible link between the promotion of specific fruit types (e.g., by public policies) and the intraspecific variation in apricot. The combination of five continuous and seven categorical traits allowed us to phenotypically distinguish the varieties; while fruit quality-related attributes displayed high variation, both apricot size and skin colour were more uniform. The twelve fluorescent-based Simple Sequence Repeats (SSRs) markers identified cultivar-specific molecular profiles and revealed a high molecular diversity, which poorly correlated with that described by the morphological analysis. Our results highlighted the complementary information provided by the two sets of descriptors and that DNA markers are necessary to separate morphologically related apricot landraces. The observed morphological and genetic differences suggest a loss of diversity influenced by maintenance breeding of specific pomological traits (e.g., skin colour and size). Finally, our study provided evidence to recommend complementary strategies to avoid the loss of diversity in apricot. Actions should pivot on both the promotion of easily identified premium products and more inclusive biodiversity-centred on-farm strategies.

Descent Of Man

Abstract In the course of his discussion of the origin of variations in skin colour among humans in the Descent of Man, Charles Darwin suggested that darker skin might be correlated with immunity to certain diseases. To make that suggestion, he drew upon a claim that seemed self-evidently correct in 1871, although it had seemed almost certainly incorrect in the late eighteenth century: that immunity to disease could be understood as a hereditary racial trait. This paper aims to show how fundamental was the idea of ‘constitutions selection’, as Darwin would call it, for his thinking about human races, tracking his (ultimately unsuccessful) attempts to find proof of its operation over a period of more than thirty years. At the same time and more broadly, following Darwin's conceptual resources on this question helps explicate relationships between conceptions of disease and conceptions of race in the nineteenth century. That period saw the birth of a modern, fixist, biologically determinist racism, which increasingly manifested itself in medical writings. The reverse was also true: medicine was a crucial site in which race was forged. The history of what has been called ‘race-science’, it is argued, cannot and should not be written independent of the history of ‘race-medicine’.

The metabolism of a Berkshire and a Middle White pig has been investigated by means of the calorimeters at the School of Agriculture, Cambridge. The general routine and technique of the observations have been as heretofore.Measurements of the fasting katabolism of each of the two pigs have been obtained in a series extending from an early age to maturity, and the phenomena in general follow the lines of those originally discovered in the Large White; but the fasting katabolism of the Middle White was below that of the Large White earlier studied.The fall in body temperature and in metabolism during the fasts were found to be correlated, and the possible effect of skin colour in this matter is noted.The effect of environmental temperature is investigated and reasons are given for supposing that the critical temperature of the Middle White pig is very low.It is concluded that the existence of a maximum somewhere in the curve showing fasting katabolism per unit area at different ages is necessitated by the two physiological facts (a) that warm blooded animals have to be maintained at a temperature which varies only within very narrow limits, and (b) that the processes of growth are accompanied by waste of energy as heat.
