Objective: Predicting disease relapse and early intervention could reduce symptom severity. We attempted to identify potential indicators that predict the duration to next admission for an acute affective episode in patients with bipolar I disorder. Methods: We mathematically defined the duration to next psychiatric admission and performed single-variate regressions using historical data of 101 patients with bipolar I disorder to screen for potential variables for further multivariate regressions. Results: Age of onset, total psychiatric admissions, length of lithium use, and carbamazepine use during the psychiatric hospitalization contributed to the next psychiatric admission duration positively. The all-in-one found that hyperlipidemia during the psychiatric hospitalization demonstrated a negative contribution to the duration to next psychiatric admission; the last duration to psychiatric admission, lithium and carbamazepine uses during the psychiatric hospitalization, and heart rate on the discharge day positively contributed to the duration to next admission. Conclusion: We identified essential variables that may predict the duration of bipolar I patients’ next psychiatric admission. The correlation of a faster heartbeat and a normal lipid profile in delaying the next onset highlights the importance of managing these parameters when treating bipolar I disorder.
Advanced Imaging of Nanometer-Scale Recorded Bits on Super-Resolution Near-Field Optical Disk

An advanced imaging technique is demonstrated for fast, non-destructive and high resolution characterizations for nanometer-scale recorded bits on a super-resolution near-field optical disk (super-RENS). For the first time, an array of individual 100 nm recorded marks is imaged and studied by using the conductive-atomic force microscopy (C-AFM) method. Discussions also include comparisons of 300 nm, 200 nm and 100 nm recorded marks on both a super-RENS disk and a commercial DVD disk, and the image results are evidence of the high carrier-to-noise ratio (CNR) value on the super-RENS disk, even though the mark size has been shrunk to less than the diffraction limit.

Transcranial direct current stimulation (tDCS), a non-invasive neuromodulation technique, has been increasingly used to treat bipolar depression. Researchers recently noticed the risk of tDCS-emergent mania/hypomania in depressed patients and started to evaluate this risk by launching a meta-analysis. Here we present a female with bipolar II depression who rapidly developed hypomanic switching during bifrontal tDCS.

Adsorption of secreted protein on contact lenses is a dynamic and complex behavior. To understand this behavior, we used three-dimensional (3D) printing technology to create an eye model that simulated the anterior segment of the actual human eyeball. In this model, the fluid inlet was connected to a syringe pump to mimic the rate of human tear secretion and the outlet was connected to an ultraviolet- visible (UV-Vis) spectrophotometer. The experimental results revealed that the symmetrical eye model with a 180° inlet-outlet angle was suitable for dynamic analysis of protein adsorption. In this model, protein adsorption was slow and desorption was rapid. The contact lens was soaked in poly(2-methacryloyloxyethyl phosphorylcholine- co-butyl methacrylate) (PMB) to confirm the anti-protein adsorption property of this polymer through dynamic adsorption and desorption eye model analysis.

Biocompatible 2-methacryloyloxyethyl phosphorylcholine (MPC) can enhance the adsorption of water molecules and is therefore used for manufacturing contact lenses. This study investigated the mechanical strength, anti-protein deposition, and anti-lipid adsorption effects of MPC addition to contact lenses. Experimental contact lenses produced by copolymerizing multiple ratios of MPC to 2-hydroxyethyl methacrylate (HEMA) were analyzed. Atomic force microscopy revealed that MPC addition increased surface roughness. The anti-protein deposition and anti-lipid adsorption effects on poly(HEMA-MPC) polymers of various phosphorylcholine quantities were experimentally confirmed. The water content of the contact lenses was proportional to the MPC content in the polymer. The hydrated PC moiety of MPC drastically altered the network of the poly-HEMA polymer by inserting water molecules, which were trapped in the concave region of the surface. MPC addition had negative effects on all examined strength factors because of structural destabilization of the copolymer through water insertion. The anti-deposition effects of MPC were verified by examining the lysozyme and lipid adsorption abilities of the prepared contact lenses. Our results revealed that MPC enhanced interactions of the poly(HEMA-MPC) copolymer with water molecules; these interactions weakened the mechanical strength of the copolymer but markedly improved the anti-adsorption property of the biomolecules. The optimal proportion of HEMA–MPC for contact lenses is in the range 14.9%-28.5%.

An Eustoma grandiflorum APETALA1 (EgAP1) gene showing high homology to the SQUA subfamily of MADS-box genes was isolated and characterized. EgAP1, containing a conserved euAP1 motif at the C-terminus, showed high sequence identity to Antirrhinum majus SQUAMOSA in the SQUA subfamily. EgAP1 mRNA was detected in the leaf and expressed significantly higher in young flower buds than in mature flower buds. In flowers, EgAP1 mRNA was strongly detected in sepal, weakly detected in petal and was absent in stamen and carpel. Transgenic Arabidopsis plants ectopically expressing EgAP1 flowered early and produced terminal flowers. In addition, the conversion of petals into stamen-like structures was also observed in 35S::EgAP1 flowers. 35S::EgAP1 was able to complement the ap1 flower defects by restoring the defect for sepal formation and significantly increasing second whorl petal production in Arabidopsis ap1 mutant plants. These results revealed that EgAP1 is the APETALA1 homolog in E. grandiflorum and that the function of EgAP1 is involved in floral induction and flower formation.
Optical metrology of randomly-distributed Au colloids on a multilayer film

<P>Spectroscopic ellipsometry (SE) measurements coupled with efficient theoretical modeling and scanning electron microscopy analysis are used in the metrology of randomly-distributed gold nanoparticles on a multilayer film. Measurements were conducted in the ultraviolet to near infrared region at several angles of incidence. To understand the size, shape, and distribution of nanoparticles, a finite-element Green's function approach considering the scattering from multiple nanoparticles was employed to calculate the ellipsometry parameters. Our calculations are in fair agreement with the ellipsometry measurements when suitable size, shape, and distribution pattern of nanoparticles are found. This demonstrates that SE could be a useful tool to the metrology of arbitrarily-distributed nanoparticles on a multilayer film.</P>
