Abstract
We experimentally explore the use of a novel device where lateral electric fields can be applied to break the translational symmetry within the isotropic plane and hence change the selection rules to allow normally forbidden transverse acoustic (TA) phonon generations. The ultrafast screening of the lateral electric field by the photocarriers relieves shear strain in the structure and switches on the propagating TA waves. The amplitude and on-state time of the TA mode can be modulated by the external field strength and size of the laterally biased region. The observed frequency shift with an external bias as well as the strong geometrical dependence confirm the role of the asymmetric potential distribution in electrically manipulating the crystal symmetry to control modal behavior of acoustic phonons.

Abstract
Capsid structure is crucial for the maturation and maintenance of the stable hepatitis B virion. Therefore, chemicals that inhibit capsid assembly might potentially act as potent antiviral compounds. However, only a few chemicals are known to block the capsid assembly process and further viral proliferation. In this study, we present a novel family of capsid assembly inhibitors that act against hepatitis B virus (HBV). Based on X-ray crystallographic data of the HBV core protein (Cp), we built dimer and hexamer structural models to be used in library searches. Several chemicals in the 2-amino-N-(2,6-dichloropyridin-3-yl)acetamide family were predicted to have high affinity for the groove structure in Cp. Using in vitro assembly and the HepG2.2.15 cell culture test, we verified that these chemicals demonstrated inhibitory effects on capsid assembly. Furthermore, we investigated the combinatorial effects of these assembly inhibitor chemicals with lamivudine and revealed that, in combination, they have synergistic inhibitory effects on decreasing viral concentration. We propose that these inhibitors could be utilized as an effective combination treatment against HBV infection.

Abstract
Exosomes are enclosed compartments that are released from cells and that can transport biological contents for the purpose of intercellular communications. Research into exosomes is hindered by their rarity. In this article, we introduce a device that uses centrifugal force and a filter with micro-sized pores to generate a large quantity of cell-derived nanovesicles. The device has a simple polycarbonate structure to hold the filter, and operates in a common centrifuge. Nanovesicles are similar in size and membrane structure to exosomes. Nanovesicles contain intracellular RNAs ranging from microRNA to mRNA, intracellular proteins, and plasma membrane proteins. The quantity of nanovesicles produced using the device is 250 times the quantity of naturally secreted exosomes. Also, the quantity of intracellular contents in nanovesicles is twice that in exosomes. Nanovesicles generated from murine embryonic stem cells can transfer RNAs to target cells. Therefore, this novel device and the nanovesicles that it generates are expected to be used in exosome-related research, and can be applied in various applications such as drug delivery and cell-based therapy.

Abstract
We have investigated the detailed features of photoluminescence (PL) in vertically aligned ZnO nanotube (NT) arrays as a function of temperature, pumping power, and experimental geometries. In samples with different wall thickness (15 or 60 nm), the temperature-dependent PL energy followed the Varshni's formula whose fitting parameters were found to be rather close to zero-dimensional case in the 15 nm-thick NTs with much larger intensity. In reflective geometry with circular excitation beam shape, the emission gradually evolved from spontaneous to stimulated regime, inferred from amplitude and line-width variation. On the other hand, in the edge-emission geometry with needle-like excitation shape, the interaction length dependence was directly traced by using an adjustable slit.

Abstract
Calbindin-D28k (CB), one of the major calcium-binding and buffering proteins, has a critical role in preventing a neuronal death as well as maintaining calcium homeostasis. Although marked reductions of CB expression have been observed in the brains of mice and humans with Alzheimer disease (AD), it is unknown whether these changes contribute to AD-related dysfunction. To determine the pathogenic importance of CB depletions in AD models, we crossed 5 familial AD mutations (5XFAD; Tg) mice with CB knock-out (CBKO) mice and generated a novel line CBKO·5XFAD (CBKOTg) mice. We first identified the change of signaling pathways and differentially expressed proteins globally by removing CB in Tg mice using mass spectrometry and antibody microarray. Immunohistochemistry showed that CBKOTg mice had significant neuronal loss in the subiculum area without changing the magnitude (number) of amyloid β-peptide (Aβ) plaques deposition and elicited significant apoptotic features and mitochondrial dysfunction compared with Tg mice. Moreover, CBKOTg mice reduced levels of phosphorylated mitogen-activated protein kinase (extracellular signal-regulated kinase) 1/2 and cAMP response element-binding protein at Ser-133 and synaptic molecules such as N-methyl-D-aspartate receptor 1 (NMDA receptor 1), NMDA receptor 2A, PSD-95 and synaptophysin in the subiculum compared with Tg mice. Importantly, this is the first experimental evidence that removal of CB from amyloid precursor protein/presenilin transgenic mice aggravates AD pathogenesis, suggesting that CB has a critical role in AD pathogenesis.
