OBJECTIVES: Mothers have a great need for information during the postnatal period. Trying to meet this need, mothers are increasingly turning to the Internet. Nevertheless, many women have stated that they often or always found that the information that they found on the Internet was incomplete or wrong. Many women therefore believe that health professionals should suggest reliable Internet websites for new mothers. The aim of this study was therefore to find a consensus on the content of a reliable and centralized website dedicated to mothers from the end of pregnancy to 1 year after childbirth...

For the first time, the scattering light of noble nanoparticles was applied for the simultaneous detection of dual cancer biomarkers. Two nanoprobes with dual scattering light colors were used for the simultaneous imaging of alpha-fetoprotein (AFP) and carcinoembryonic antigen (CEA) based on the sandwich-type immunoassay. Since AFP can combine anti-AFP-modified gold nanoparticles which have green scattering light under dark-field microscopic imaging (iDFM) technique while CEA can conjugate anti-CEA-immobilized silver nanoparticles which have blue scattering light, the simultaneous determination of AFP and CEA can be achieved by separately counting the number of green and blue light spots in iDFM technique...

REVIEW
Rachael J Oakenfull, Seth J Davis
The circadian clock provides essential timing information to ensure optimal growth to prevailing external environmental conditions. A major time-setting mechanism (zeitgeber) in clock synchronisation is light. Differing light wavelengths, intensities and photoperiodic duration are processed for the clock-setting mechanism. Many studies on light-input pathways to the clock have focused on Arabidopsis thaliana. Photoreceptors are specific chromic proteins that detect light signals and transmit this information to the central circadian oscillator through a number of different signalling mechanisms...

INTRODUCTION: Postpartum depression (PPD) affects approximately 14% of women in the United States and 10% to 37% of Arabic women in the Middle East. Evidence suggests that immigrant women experience higher rates, but information on PPD among immigrant women of Arabic descent in the United States is nonexistent. METHODS: A cross-sectional descriptive feasibility study was conducted to assess the practicality of implementing a larger proposed research study to examine predictors of PPD in US immigrant women of Arabic descent residing in Dearborn, Michigan...

A new class of tridentate ligand-containing cyclometalated gold(III) complexes featuring dendritic alkynyl ligands with carbazole moieties as dendrons and peripheral groups has been synthesized up to the third generation. High-performance solution-processable organic light-emitting devices (OLEDs) with maximum current efficiency of up to 23.7 cd A(-1) and external quantum efficiency of up to 6.9% have been realized by a simple spin-coating technique. With the incorporation of bulky carbazole moieties to form higher generation dendrimers, the undesirable excimeric emission could be effectively reduced, allowing the fine-tuning of the emission color toward the blue region...

We demonstrate an electrochromic device with self-bleaching ability that uses ethyl viologen- ([EV](2+)) and ferrocene-based redox ionic liquids ([FcNTf](-)) as the electroactive species. These electroactive compounds are insensitive to atmospheric O2 and H2O in both their oxidized and reduced states once dissolved in a typical ionic liquid electrolyte ([BMIm][NTf2]), allowing for the device to be assembled outside a glovebox without any encapsulation. This device could generate a deep blue color by applying a 2...

Subsequent to the publication of the above paper, the authors noted that there was an error on Fig. 4 of page 2046, in which the symbols of α-L-fucosidase 1 (FUCA1) and fucosyltransferase 8 (FUT8) had been mistakenly labelled the wrong way around (FUCA1 should have been represented by the blue bars, and FUT8 by the red). The corrected version of Fig. 4 is shown below, which now accurately shows how average levels of FUCA1 mRNA were low in the anaplastic thyroid cancer samples (ATCs), whereas expression levels in the papillary thyroid cancer samples (PTCs) were comparable, or slightly higher, than those present in normal thyroid tissues...

Both symmetrical and unsymmetrical cyclophanes containing disilane units, tetrasila[2.2]cyclophanes 1-9, were synthesized. The syn and anti conformation and the kinetics of inversion between two anti-isomers were investigated by X-ray diffraction and variable-temperature NMR analysis, respectively. The flipping motion of two aromatic rings was affected by the bulkiness of the aromatic moiety (1 vs 6), the phase (solid vs solution), and the inclusion by host molecules (1 vs 1⊂[Ag2L](2)(+)). The photophysical, electrochemical, and structural properties of the compounds were thoroughly investigated...

Mitochondria play a central role in cellular energy metabolism and cell death. Deregulation of mitochondrial functions is associated with several human pathologies (neurodegenerative diseases, neuromuscular diseases, type II diabetes, obesity, cancer). The steadily increasing number of identified mitochondrial phosphoproteins, kinases, and phosphatases in recent years suggests that reversible protein phosphorylation plays an important part in the control of mitochondrial processes. In addition, many mitochondrial phosphoproteins probably still remain to be identified, considering that 30% of proteins are expected to be phosphorylated in eukaryotes...

Paralytic shellfish toxins (PSTs) are potent neurotoxins produced by marine dinoflagellates that are responsible for paralytic shellfish poisoning (PSP) in humans. This work highlights our ongoing efforts to develop quantitative methods for PSTs using hydrophilic interaction liquid chromatography-tandem mass spectrometry (HILIC-MS/MS). Compared with the commonly used method of liquid chromatography with post-column oxidation and fluorescence detection (LC-ox-FLD), HILIC-MS/MS has the potential of being more robust, sensitive and straightforward to operate, and provides unequivocal confirmation of toxin identity...

Three-dimensional photonic crystal sensors are attractive platforms for autonomous chemical sensing and colorimetric bioassays. At present, the photonic crystal sensors with inverse opal structure were extensively studied, which swells or shrinks in response to the analytes. However, the fabrication of inverse opal sensors still remains a major challenge. Herein, we propose a simple and versatile approach to fabricate 3D opal photonic sensors. This photonic crystal is fabricated via assembly of monodispersed silica particles grafted with linear polymeric ligands (SiO2@LPs)...

To perform various physiological functions, erythrocytes possess a unique biconcave shape provided by a special architecture of the membrane-skeleton system. In the present work, we use a simple irradiation method to treat human erythrocytes with 365 nm ultraviolet-A (UVA) light at the single-cell level in vitro. Depending on the irradiation dose, UVA show protection of the biconcave profile against the detrimental action of distilled water. This protective effect can also be confirmed for saponin that damages the membrane-skeleton by vesiculation and pore formation...

Microgels are intra-molecular crosslinked macromolecules that can be used as vehicles to deliver and release drugs at the point-of-need in the patient's body. Here, gelatin microgels were formed from microfluidics droplets, stabilised by aldehydes and frozen into a spheroidal shape. Microgel morphology and response to external stimuli were characterised. It was found that the behaviour of the spheroidal microgels was sensitive to both pH and ionic strength and that the distribution of charges into the microgels affected the behaviour of swelling and uptake...
