Colour as an environmental effect on interpersonal affective behaviour

The present study primarily concerns the relationship between coloured lighting (red and blue, with white as an achromatic control) and attraction toward another individual; an individual who may have similar or dissimilar attitudes to those of the subject. The question asked was whether the colour of a room's illumination affected interpersonal evaluation of another person whom the subject had not previously met. That is, will coloured illumination affect liking of the stranger either negatively or positively, over and above the effect that knowledge of the stranger's attitudes will have on the subject's judgement? Is attraction a function of colour of environmental illumination and attitude similarity? Questions subsidiary to the above but of basic importance to the present study are; whether mood is affected positively or negatively by coloured room environment; whether concepts are more negatively or positively evaluated under different colour conditions and whether aspects of semantic meaning are differentially affected under different lighting conditions. Finally Berry's (1961) finding of different heat perception over colour environments was retested

Dealing with the deluge of historical weather data: the example of the TEMPEST database

People have long been interested in the history of weather, particularly extremes, and chronologies of past events drawing on information from written records, have been compiled and published throughout history. In recent years, concern over current and future weather and climate has triggered a new level of interest in past weather events and their impacts. This interest, alongside the development of digital humanities research methods has resulted in a rapid growth in the number of online databases relating to historic weather and climate around the world. This paper reviews this expansion with reference to a range of examples, before documenting the design and creation of one such database, TEMPEST, an online repository for extreme weather history in the UK. TEMPEST has been created as the major output of the AHRC funded project ?Spaces of Experience and Horizons of Expectation: Extreme Weather in the UK, Past, Present and Future? (2013-2016). Unlike the majority of existing databases that rely on published materials, TEMPEST?s records are drawn from primary research into original documentary sources held in archives around the UK. The c. 18,000 records that TEMPEST currently contains offer personalised and geo-referenced insights into the relationship between society and extreme weather in the UK spanning a period of over 400 years. We conclude this paper by outlining some potential applications for TEMPEST, and suggesting directions for future research and resources in historical weather. We also consider broader issues for the digital humanities.publishersversionPeer reviewe

A role for two-pore potassium (K2P) channels in endometrial epithelial function.

The human endometrial epithelium is pivotal to menstrual cycle progression, implantation and early pregnancy. Endometrial function is directly regulated by local factors that include pH, oxygen tension and ion concentrations to generate an environment conducive to fertilization. A superfamily of potassium channels characterized by two-pore domains (K2P) and encoded by KCNK genes is implicated in the control of the cell resting membrane potential through the generation of leak currents and modulation by various physicochemical stimuli. The aims of the study were to determine the expression and function of K2P channel subtypes in proliferative and secretory phase endometrium obtained from normo-ovulatory women and in an endometrial cancer cell line. Using immunochemical methods, real-time qRT-PCR proliferation assays and electrophysiology. Our results demonstrate mRNA for several K2P channel subtypes in human endometrium with molecular expression of TREK-1 shown to be higher in proliferative than secretory phase endometrium (P < 0.001). The K2P channel blockers methanandamide, lidocaine, zinc and curcumin had antiproliferative effects (P < 0.01) in an endometrial epithelial cancer cell line indicating a role for TASK and TREK-1 channels in proliferation. Tetraethylammonium- and 4-aminopyridine-insensitive outwards currents were inhibited at all voltages by reducing extracellular pH from 7.4 to 6.6. Higher expression of TREK-1 expression in proliferative phase endometrium may, in part, underlie linked to increased cell division. The effects of pH and a lack of effect of non-specific channel blockers of voltage-gated potassium channels imply a role for K2P channels in the regulation of human endometrial function

Review article: pathogenesis and clinical manifestations of gastrointestinal involvement in systemic sclerosis.

BACKGROUND: Gastrointestinal tract (GIT) involvement is a common cause of debilitating symptoms in patients with systemic sclerosis (SSc). There are no disease modifying therapies for this condition and the treatment remains symptomatic, largely owing to the lack of a clear understanding of its pathogenesis. AIMS: To investigate novel aspects of the pathogenesis of gastrointestinal involvement in SSc. To summarise existing knowledge regarding the cardinal clinical gastrointestinal manifestations of SSc and its pathogenesis, emphasising recent investigations that may be valuable in identifying potentially novel therapeutic targets. METHODS: Electronic (PubMed/Medline) and manual Google search. RESULTS: The GIT is the most common internal organ involved in SSc. Any part of the GIT from the mouth to the anus can be affected. There is substantial variability in clinical manifestations and disease course and symptoms are nonspecific and overlapping for a particular anatomical site. Gastrointestinal involvement can occur in the absence of cutaneous disease. Up to 8% of SSc patients develop severe GIT symptoms. This subset of patients display increased mortality with only 15% survival at 9 years. Dysmotiity of the GIT causes the majority of symptoms. Recent investigations have identified a novel mechanism in the pathogenesis of GIT dysmotility mediated by functional anti-muscarinic receptor autoantibodies. CONCLUSIONS: Despite extensive investigation, the pathogenesis of gastrointestinal involvement in systemic sclerosis remains elusive. Although treatment currently remains symptomatic, an improved understanding of novel pathogenic mechanisms may allow the development of potentially highly effective approaches including intravenous immunoglobulin and microRNA based therapeutic interventions

From Analogical Proportion to Logical Proportions

International audienceGiven a 4-tuple of Boolean variables (a, b, c, d), logical proportions are modeled by a pair of equivalences relating similarity indicators ( a∧b and a¯∧b¯), or dissimilarity indicators ( a∧b¯ and a¯∧b) pertaining to the pair (a, b), to the ones associated with the pair (c, d). There are 120 semantically distinct logical proportions. One of them models the analogical proportion which corresponds to a statement of the form “a is to b as c is to d”. The paper inventories the whole set of logical proportions by dividing it into five subfamilies according to what they express, and then identifies the proportions that satisfy noticeable properties such as full identity (the pair of equivalences defining the proportion hold as true for the 4-tuple (a, a, a, a)), symmetry (if the proportion holds for (a, b, c, d), it also holds for (c, d, a, b)), or code independency (if the proportion holds for (a, b, c, d), it also holds for their negations (a¯,b¯,c¯,d¯)). It appears that only four proportions (including analogical proportion) are homogeneous in the sense that they use only one type of indicator (either similarity or dissimilarity) in their definition. Due to their specific patterns, they have a particular cognitive appeal, and as such are studied in greater details. Finally, the paper provides a discussion of the other existing works on analogical proportions

Exclusion and reappropriation: Experiences of contemporary enclosure among children in three East Anglian schools

Transformations of the landscapes which children inhabit have significant impacts on their lives; yet, due to the limited economic visibility of children’s relationships with place, they have little stake in those transformations. Their experience, therefore, illustrates in an acute way the experience of contemporary enclosure as a mode of subordination. Following fieldwork in three primary schools in South Cambridgeshire, UK, we offer an ethnographic account of children’s experiences of socio-spatial exclusion. Yet, we suggest that such exclusion is by no means an end-point in children’s relationships with place. Challenging assumptions that children are disconnected from nature, we argue that through play and imaginative exploration of their environments, children find ways to rebuild relationships with places from which they find themselves excluded.

The Concise Guide to PHARMACOLOGY 2023/24:Catalytic receptors

The Concise Guide to PHARMACOLOGY 2023/24 is the sixth in this series of biennial publications. The Concise Guide provides concise overviews, mostly in tabular format, of the key properties of approximately 1800 drug targets, and nearly 6000 interactions with about 3900 ligands. There is an emphasis on selective pharmacology (where available), plus links to the open access knowledgebase source of drug targets and their ligands (https://www.guidetopharmacology.org/), which provides more detailed views of target and ligand properties. Although the Concise Guide constitutes almost 500 pages, the material presented is substantially reduced compared to information and links presented on the website. It provides a permanent, citable, point-in-time record that will survive database updates. The full contents of this section can be found at http://onlinelibrary.wiley.com/doi/10.1111/bph.16180. Catalytic receptors are one of the six major pharmacological targets into which the Guide is divided, with the others being: G protein-coupled receptors, ion channels, nuclear hormone receptors, enzymes and transporters. These are presented with nomenclature guidance and summary information on the best available pharmacological tools, alongside key references and suggestions for further reading. The landscape format of the Concise Guide is designed to facilitate comparison of related targets from material contemporary to mid-2023, and supersedes data presented in the 2021/22, 2019/20, 2017/18, 2015/16 and 2013/14 Concise Guides and previous Guides to Receptors and Channels. It is produced in close conjunction with the Nomenclature and Standards Committee of the International Union of Basic and Clinical Pharmacology (NC-IUPHAR), therefore, providing official IUPHAR classification and nomenclature for human drug targets, where appropriate.</p
