A potent fluorescence 'turn-on' receptor (HL) based on rhodamine and coumarin moieties for the detection of Hg(2+) and Al(3+) is synthesized by condensation of rhodamine 6G hydrazide and 4-hydroxy-3-acetylcoumarin. In presence of Al(3+) and/or Hg(2+) the receptor (HL) exhibits deep pink colouration and a sharp band at 528 nm is appeared in UV-vis titration. Upon gradual addition of Al(3+) and/or Hg(2+) to the solution of HL significant enhancement of fluorescence intensity is observed at 564 nm in MeCN:H2O (1:5, v/v) medium...

A moderately halophilic bacterium, designated strain SP30T, was isolated from a solar saltern located in Santa Pola, Alicante, on the East coast of Spain. It was a Gram-stain-negative, strictly aerobic bacterium, able to grow in 7.5-25 % (w/v) NaCl and optimally in 12.5 % (w/v) NaCl. Phylogenetic analyses, based on 16S rRNA gene sequences, showed that the novel isolate is a member of the genus Spiribacter, with the most closely related species being Spiribacter roseus SSL50T (99.9 % sequence similarity) and Spiribacter curvatus UAH-SP71T (99...

A bacterial strain designated LYH-12T was isolated from a freshwater fish culture pond in Taiwan, ROC and characterized by taking a polyphasic taxonomy approach. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain LYH-12T belonged to the genus Hymenobacter and was most closely related to Hymenobacter xinjiangensis X2-1gT and Hymenobacter rigui WPCB131T with a sequence similarity of 96.6 % and less than 96.5 % with other members of the genus. Cells of strain LYH-12T were Gram-stain-negative, aerobic, non-motile rods that were covered by large capsules and formed light pink-coloured colonies...

Escape behaviors in peneid shrimp are mediated by large myelinated medial giant fibers which course from the brain to the last abdominal ganglion in the ventral nerve cord. In each abdominal segment the medial giant axons make synaptic connections with paired myelinated giant motor axons that excite the abdominal deep flexor muscles and drive the tailflips that constitute the escape behavior. I examined 1) anatomical features of the abdominal motor giant fibers and 2) electrical properties of both the medial giants and motor giants in the pink shrimp, Farfantepenaeus duoarum...

This study investigated the effects of ethnic minority adolescents' ethnic self-identification (host country, dual, or heritage country) on friendship choices among ethnic majority and minority peers. Hypotheses were derived from similarity-attraction and social identity theory and tested using longitudinal social network data from 1,004 middle school students (five schools) in Germany. Results showed that ethnic minority adolescents' ethnic self-identification affected friendship selection beyond ethnic homophily...

Heliconia berguidoi (Heliconiaceae), a new species from premontane forest of eastern Panama, is described, illustrated and its conservation status evaluated. Heliconia berguidoi bears pink flowers, an uncommon color in this group. It differs from the Colombian species Heliconia rhodantha and Heliconia sanctae-theresae, the most similar taxa, by the combination of a petiole glabrous except for the woolly base, a very long peduncle, the perianth pubescent at the apex and staminode with cuspidate apex. Heliconia berguidoi is also similar to Heliconia pogonantha in all four of its varieties and to Heliconia ramonensis in two of its four varieties, but differs by a combination of the long peduncle, pink flowers and staminode with cuspidate apex...

The complex (PNP)Ti=CHtBu(CH2tBu) (PNP = N[2-PiPr2-4-methylphenyl]2-) dehydrogenates cyclohexane to cyclohexene by forming a transient low-valent titanium-alkyl species, [(PNP)Ti(CH2tBu)], which reacts with two equivalents of quinoline (Q) at room temperature to form H3CtBu and a Ti(IV) species where the less hindered C2=N1 bond of Q is ruptured and coupled to another equivalent of Q. The product isolated from this reaction is an imide with a tethered cycloamide group, (PNP)Ti=N[C18H13N] (1). Under photolytic conditions, intramolecular C-H bond activation across the imide-moiety in 1 occurs to form 2, and thermolysis reverses this process...

Cutaneous lymphadenoma is an uncommon benign neoplasm often considered to be an adamantinoid variant of trichoblastoma. Lesions present in both sexes, between 14 and 87 years of age, and are mainly located on the head and neck. Cases in children are rare and there is only one previous case of a congenital lymphadenoma. An 8-year-old Asian girl presented with a congenital lesion on her forehead comprising four pink papules, the largest 5 mm in diameter. Microscopy revealed a well circumscribed tumor within the dermis and subcutis comprising well demarcated epithelial lobules of basaloid and clear cells with subtle peripheral palisading, growing in a collagenous stroma but lacking retraction artefact...

Evaluation of seed protein alleles in soybean populations showed that an increase in protein concentration is generally associated with a decrease in oil concentration and yield. Soybean [Glycine max (L.) Merrill] meal is one of the most important plant-based protein sources in the world. Developing cultivars high in seed protein concentration and seed yield is a difficult task because the traits have an inverse relationship. Over two decades ago, a protein quantitative trait loci (QTL) was mapped on chromosome (chr) 20, and this QTL has been mapped to the same position in several studies and given the confirmed QTL designation cqSeed protein-003...

A new species, Cherax warsamsonicussp. n., endemic to the Warsamson River drainage, in the western part of the Kepala Burung (Vogelkop) peninsula, West Papua, Indonesia, is described, figured and compared with its closely related species, Cherax misolicus Holthuis, 1949. The new species may be easily distinguished from C. misolicus by the shape of the rostrum, absence of setae on the rostrum, the shape of the chelae, the presence of 3-4 cervical spines and by using sequence divergence, which is substantial for considering C...

BACKGROUND/PURPOSE: Hailey-Hailey disease is a rare inherited acantholytic skin disorder characterized by heterogeneous clinical presentation. Its differential diagnosis might be wide, including other genodermatoses, inflammatory, and infectious skin diseases. Although histopathology remains as diagnostic gold standard, noninvasive techniques such as dermoscopy and reflectance confocal microscopy may assist clinical examination. Herein, we aim to further characterize the dermoscopic and reflectance confocal microscopic presentation of Hailey-Hailey disease with histologic correlation...

In 2012, the US actress Cynthia Nixon was quoted in New York Times Magazine as having stated that "for me, it [being gay] is a choice. I understand that for many people it's not, but for me it's a choice, and you don't get to define my gayness for me". The interview attracted international media attention and public criticism by lesbian and gay activists. This paper suggests a rhetorical approach to understanding etiological beliefs and provides a discursive analysis of 198 online comments by readers of Pink News, a gay news website which reported on Nixon's controversial interview...

OBJECTIVE: To describe the characteristic retinal features of lipemia retinalis when using ultrawide field scanning laser ophthalmoscopy. MAIN POINTS: We report a case series of three subjects with ultrawide field retinal images showing cream discoloration of the fundus, light salmon-coloured posterior retinal vessels and greyish pink peripheral vasculature. On green-only imaging, many of the vessels appear light rather than typically dark. CONCLUSION: Lipemia retinalis is readily apparent on ultrawide field imaging and illustrates the alterations that systemic diseases may induce in the posterior and peripheral retinal vasculature...

Strain P4487AT was isolated during investigation of cultivable bacterial populations of environmental materials sampled at James Ross Island, Antarctica. It revealed Gram-stain-negative short rod-shaped cells producing a pink pigment. Phylogenetic analysis based on 16S rRNA gene sequences allocated strain P4487AT to the genus Pedobacter but showed that the strain represents a distinct intrageneric phylogenetic lineage clearly separated from remaining Pedobacter species. Phylogenetically, strain P4487AT formed a common branch with the Pedobacter arcticus and Pedobacter lignilitoris cluster while the highest value of 94...
