The nutritional quality of daphnids diet can influence their growth, reproduction and survival. In aquatic ecosystems, bacteria can contribute significantly to Daphnia diet by supporting, for instances, their high needs for phosphorus. The laboratory feeding of the model organisms Daphnia spp. is algal based, but should be improved to allow their better performance. The aim of this study was to evaluate the potential of two planctomycetes, Gemmata obscuriglobus and Rhodopirellula rubra, from exponential and stationary growth phases as alternative or supplementary food source for Daphnia magna...

A pink-coloured bacterial strain, TAPP7T, was isolated from a freshwater creek in Taiwan. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain TAPP7T belonged to the genus Mucilaginibacter and showed highest similarity with Mucilaginibacter ginsengisoli B4Y-8T (97.6 %) and Mucilaginibacter carri PR0008KT (96.9 %). Cells of strain TAPP7T were Gram-staining-negative, aerobic, poly-β-hydroxybutyrate-accumulating and short-rod-shaped. Growth occurred at 10-30 °C (optimum, 15-20 °C), at pH 4-8 (optimum, pH 6) and with 0-1 % NaCl (optimum, 0...

A new rapid, sensitive and selective method for rotavirus detection in water samples is described in this paper. Amino pink magnetic microparticles were functionalized with monoclonal antibodies and used to capture, concentrate, separate and detect infectious rotavirus particles in distilled and drinking water samples. The fluorescence of the microparticles was used to determine the presumptive presence of rotaviruses by using confocal microscopy. Atomic force microscopy and transmission electron microscopy were used to confirm the presence of the anti-rotavirus antibodies attached to the surface of the magnetic microparticles as well as that of viruses attached through the antibody...

We present an unusual onset of cutaneous lichen planus (LP) in a middle-aged patient. The initial presentation as solitary, indolent pink lesion required further investigations to rule out malignancy, especially amelanotic melanoma. Dermoscopy and reflectance confocal microscopy findings were found to be helpful in our case in addressing the correct diagnosis.

Here, we present a controlled synthesis of Mn-doped ZnO nanoparticles (NPs) with predominantly nail-like shapes, whose formation occurs via tip-to-base oriented attachment of initially formed nanopyramids, followed by levelling of sharp edges that lead to smooth single-crystalline "nails". This shape is prevalent in non-coordinating solvents such as octadecene and octadecane. Yet, the double bond in the former promotes oriented attachment. In contrast, Mn-doped ZnO NP synthesis in a weakly coordinating solvent, benzyl ether, results in dendritic structures due to random attachment of initial NPs...

Process control for manufacturing biologics is critical for ensuring product quality, safety and lot to lot consistency of therapeutic proteins. In this study, we investigated the root cause of the pink coloration observed for various in-process pools and drug substances in the antibody manufacturing process. Vitamin B12 is covalently bound to mAbs via a cobalt-sulfur coordinate bond via the cysteine residues. The vitamin B12 was identified to attach to an IgG4 molecule at cysteine residues on light chain (Cys-214), and heavy chain (Cys-134, Cys-321, Cys-367 and Cys-425)...

Two strains, 08MAS2251T and LZ2016-166, were isolated from diverse samples in China collected from the surface of crucian carp and the faeces of a diarrhoea patient, respectively. Both strains were pink-orange coloured, Gram-negative, oxidase- and catalase-positive, facultative anaerobic and motile bacteria, produced H2S and reduced nitrates to nitrites. Growth occurred in the presence of 0-9 % (w/v) NaCl and at 10-42 °C. The optimum conditions were with 1 % (w/v) NaCl and at 35 °C. The phylogenetic tree of 16S rRNA gene demonstrated that strains 08MAS2251T and LZ2016-166 clustered in a distinctive clade next to the species Shewanella chilikensis JC5T within the genus Shewanella...

The first molecular phylogenetic hypothesis for the possibly extinct pink-headed duck Rhodonessa caryophyllacea unambiguously shows that it belongs to the pochard radiation that also includes the genera Aythya and Netta. It is the sister to all modern-day pochards and belongs to a lineage that branched off from the others more than 2.8 million years ago. Rhodonessa caryophyllacea is believed to never have been common in modern time and we show this has probably been the situation for as long as 100,000 years...

Objective: The use of methylene blue dye (MB) to highlight anatomical structures in urology has been well-established. Urethral stricture may extend about a centimeter beyond the abnormal area seen on urethrogram. Although the current literature suggests a tension-free and end- to- end anastomosis after excision of the strictured urethral segment with spongiofibrosis and surrounding corpus spongiosum in short bulbar strictures, some centers dealing with urethroplasty prefer anastomosis for short bulbar strictures while others prefer augmentation...

The increasing number and quality of sensors integrated in mobile phones have paved the way for sensing schemes driven by city dwellers. The sensing quality can drastically depend on the mobile phone, and appropriate calibration strategies are needed. This paper evaluates the quality of noise measurements acquired by a variety of Android phones. The Ambiciti application was developed so as to acquire a larger control over the acquisition process. Pink and narrowband noises were used to evaluate the phones' accuracy at levels ranging from background noise to 90 dB(A) inside the lab...

PURPOSE: The management of pulseless supracondylar fractures remains controversial. The aims of this study were to: (1) analyse functional and vascular outcomes of conservative treatment for cases with absent pulse before reduction, whether patients showed limb ischaemia or not; and (2) identify factors associated with vascular complications. METHODS: Twenty-seven children with absent pulses on presentation were treated consecutively between 1999 and 2009. The brachial artery was surgically explored in cases of persistent signs of ischaemia after reduction...

A new colorimetric fluorescent probe (MCy) for CN- is designed and synthesized based on triphenylimidazole-hemicyanine dyad. The probe shows high selectivity towards CN- in 100% aqueous solution even in the presence of other competitive anions such as F-, Cl-, AcO-, NO2-, H2PO4-, I-, SCN-, SO42-, NO3-, HCO3-, Br- and S2-. Upon nucleophilic addition of CN- to the indolium group, the probe displays large blue-shift in UV-vis spectrum and remarkable "turn-on" fluorescence owing to the disruption of intramolecular charge transfer...
