• Floral color is a key reproductive character, often associates with environmental adaptation, and undergoes human intervention. A large number of Rhododendron species spread widely with various flower colors, which makes a good model for flower coloration. The chromatic features and anthocyanin compositions of 30 species from seven subgenera were systematically analyzed. • The Royal Horticultural Society Color Chart and CIE L*a*b* system were employed to describe and investigate flower colors. The UPLC-PDA/ESI-MS(n) system was used to identify and quantify anthocyanins in petal extracts...

This work was aimed to develop a chemical sensor for the determination of total polyphenol content (TPC) of coffee samples. The polyphenol sensor was based on co-immobilization of NaIO4 and MBTH in paper as a test strip. The sensor showed sensitive response to chlorogenic acid by forming pink color adduct which can be scanned and quantified by Imagej program. The sensor had response time of 14 min and a linear range between 0.07 and 0.71 mM of chlorogenic acid with a detection limit at 0.002 mM toward chlorogenic acid...

A major challenge in urban ecology is to identify the environmental factors responsible for phenotypic differences between urban and rural individuals. However, the intercorrelation between the factors that characterize urban environments, combined with a lack of experimental manipulations of these factors in both urban and rural areas, hinder efforts to identify which aspects of urban environments are responsible for phenotypic differences. Among the factors modified by urbanization, anthropogenic sound, particularly traffic noise, is especially detrimental to animals...

According to estimates from Public Health England, by 2034 70% of adults are expected to be overweight or obese, therefore understanding the underpinning aetiology is a priority. Eating in response to negative affect contributes towards obesity, however, little is known about the underlying mechanisms. Evidence that visceral afferent signals contribute towards the experience of emotion is accumulating rapidly, with the emergence of new influential models of 'active inference'. No longer viewed as a 'bottom up' process, new interoceptive facets based on 'top down' predictions have been proposed, although at present it is unclear which aspects of interoception contribute to aberrant eating behaviour and obesity...

This communication reports on the design and synthesis of mechanochromophores with a dynamic covalent system composed of a tetraarylsuccinonitrile skeleton that generate a metastable organic luminescent carbon radical. The mechanically generated radical species showed pink color and yellow light emission under UV irradiation. Unusually high stability of the luminescent carbon-centered radicals was also observed in a polymer system.

A 70-year-old-woman developed anisocoria after applying homeopathic eye drops (Similasan Pink Eye Relief) to her left eye. Her pupil was dilated for two weeks and did not respond to light or near stimuli for one week. Both 0.1 % and 1% pilocarpine failed to constrict her left pupil, and magnetic resonance imaging of her brain did not reveal any abnormality. The eye drops she had used contain belladonna extracts, which have a natural atropine component. This case demonstrates the importance, when evaluating a patient presenting with anisocoria, of knowing the chemical ingredients of the homeopathic eye drops, which often are not listed...

Two strains of thermotolerant phototrophic alphaproteobacteria, designated strains TUT3542(T) and TUT3581(T), were isolated from sediment mud and cyanobacterial mats in a geothermal spring in Japan, respectively, and taxonomically characterized. Both the strains were budding motile rods and were able to grow at 45 °C. Phototrophically grown cells of strains TUT3542(T) and TUT3581(T) produced pink and brownish red cultures, respectively, and showed in vivo absorption maxima at 800, 858-859 and 892-895 nm in the near infrared region, indicating the presence of a core reaction centre and peripheral pigment complexes with bacteriochlorophyll a...

BACKGROUND: Many serological tests have been used for the diagnosis of human brucellosis. A new serological method is identified as Brucella Coombs gel test based on the principle of centrifugation gel system similar to the gel system used in blood group determination. In this system, if Brucella antibodies were present in the serum, antigen and antibody would remain as a pink complex on the gel. Otherwise, the pink Brucella antigens would precipitate at the bottom of the gel card system...

Developing some methods that can simply and effectively detect mercury ions (Hg(2+)) in the environment and biological systems are very important due to the problems of high toxicity and biological accumulation. Herein, we report a simple rhodol-derived colorimetric and fluorescent probe rhodol-Hg with a recognition receptor of carbonothioate for the specific determination of Hg(2+). The color of probe rhodol-Hg solution changed remarkably from colorless to pink in the presence of Hg(2+), thus rhodol-Hg could act as a "naked-eye" probe for Hg(2+)...

Water-clear cell adenoma of the parathyroid gland is a rare neoplasm that consists of cells with abundant clear-pink cytoplasm. There have only been 19 cases reported in the English literature. Here we report a case of water-clear cell adenoma of the mediastinal parathyroid gland. A 70-year-old male patient presented to the hospital with back pain and a mediastinal mass 6 cm in size was detected. After excision and microscopic evaluation, uniform, large clear cells with fine cytoplasmic vacuolization, without nuclear atypia, and arranged in solid and acinar patterns were revealed...

Strain ANT-18(T), isolated from a water sample taken from the Longtoushan Spring in Taiwan, was characterized using a polyphasic taxonomic approach. Cells of strain ANT-18(T) were Gram-stain-negative, aerobic, motile by gliding rods that were surrounded by a thick capsule and it formed pink colonies. Growth occurred at 20-37 °C (optimum, 25 °C), at pH 6-8 (optimum, pH 7) and with 0-1 % NaCl (w/; optimum, 0 %). Phylogenetic analyses, based on 16S rRNA gene sequences, showed that strain ANT-18(T) belongs to the genus Hymenobacter and showed the highest levels of sequence similarity to Hymenobacter ocellatus Myx 2105(T) (97...

In their recent article published in the journal Scientific Reports, Büntgen and Di Cosmo have attempted to solve the historical mystery of the sudden Mongol withdrawal from Hungary after a year-long occupation. We cannot share the authors' viewpoint that environmental circumstances contributed to the decision of the Mongols to abandon Hungary since the hypothesis lacks support from environmental, archaeological and historical evidence. Historical source material in particular suggests that the Mongols were able to settle and sustain their herds in Hungary as is clearly stated in a letter by King Bela IV to the pope...

In our 2016 article in Scientific Reports, we advanced a new hypothesis for the Mongol withdrawal from Hungary in 1242 CE, based on a joint analysis of climatic, environmental, and historical data. The re-evaluation now offered by Pinke et al. casts doubt on this hypothesis. However, their arguments are based on a level of generality that fails to appreciate the specific conditions of the Mongol invasion, do not offer new or different climatic data, and are supported by anachronistic production data and environmental information, which cannot be related to the period in question...

We investigated how population changes and fluctuations in the pink-footed goose might have been affected by climatic and anthropogenic factors. First, genomic data confirmed the existence of two separate populations: western (Iceland) and eastern (Svalbard/Denmark). Second, demographic inference suggests that the species survived the last glacial period as a single ancestral population with a low population size (100-1,000 individuals) that split into the current populations at the end of the Last Glacial Maximum with Iceland being the most plausible glacial refuge...

Geophagy, the deliberate consumption of earth materials, is common among humans and animals. However, its etiology and function(s) remain poorly understood. The major hypotheses about its adaptive functions are the supplementation of essential elements and the protection against temporary and chronic gastrointestinal (GI) distress. Because much less work has been done on the protection hypothesis, we investigated whether soil eaten by baboons protected their GI tract from plant secondary metabolites (PSMs) and described best laboratory practices for doing so...

Mitochondria are indispensable cellular organelles providing ATP and numerous other essential metabolites to ensure cell survival. Reactive oxygen species (ROS), which are formed as side reactions during oxidative phosphorylation or by external agents, induce molecular damage in mitochondrial proteins, lipids/membranes, and DNA. To cope with this and other sorts of organellar stress, a multi-level quality control system exists to maintain cellular homeostasis. One critical level of mitochondrial quality control is the removal of damaged mitochondria by mitophagy...

One challenging feature of head and neck pathology is that a dizzying array of spindle cell lesions occurs here which ranges all the way from reactive, very aggressive forms to malignant lesions. Leiomyosarcoma is one such malignant tumour of mesenchymal origin exhibiting smooth muscle differentiation; presenting generally nonspecific signs and symptoms. Here we present a case of leiomyosarcoma in a 21 year old female patient associated with single reddish pink swelling present in the posterior right maxillary tuberosity region with moderate facial asymmetry...
