Arsenic poisoning from drinking water has been an important global issue in recent years. Because of the high level toxicity of arsenic to human health, an easy, inexpensive, low level and highly selective detection technique is of great importance to take any early precautions. This study reports the synthesis of Ag doped hollow CdS/ZnS bi-layer (Ag-h-CdS/ZnS) nanoparticles for the easy fluoro...

BACKGROUND The root of Peucedanum japonicum Thunb., a perennial herb found in Japan, the Philippines, China, and Korea, is used as an analgesic. In a previous study, sec-O-glucosylhamaudol (SOG) showed an analgesic effect. This study was performed to examine the antinociceptive effect of intrathecal SOG in the formalin test. METHODS Male Sprague-Dawley rats were implanted with an intrathecal ...

In this work, we present a method able to fabricate thin GaN nanomembranes fit for device applications. Starting from commercial GaN on sapphire substrates, MBE was used to deposit a sacrificial layer, which comprises of a superlattice of InN/InGaN, after which thin a GaN film of hundreds of nanometers thickness was grown on top. Pulsed laser irridiation with photon energy of 2.3eV gives rise t...

This article presents a set of low-temperature deposition and etching processes for the integration of electrochemically deposited Ni-Fe alloys in complex magnetic microelectromechanical systems, as Ni-Fe is known to suffer from detrimental stress development when subjected to excessive thermal loads. A selective etch process is reported which enables the copper seed layer used for electrodepos...

Two soft lithography based fabrication techniques were employed for fabricating mechanically independent, freely suspended polymer microstructure from poly(n-propyl methacrylate) (PPMA) and poly(methyl methacrylate) (PMMA). Both methods involve a micromolding process followed by thermal bonding to the substrate. The first method, sacrificial layer micromolding, uses a water-soluble sacrificial ...

We demonstrate an array of solid-state dye-sensitized solar cells (SS-DSSCs) for a high-voltage power source based on micropatterned titanium dioxide nanoparticles (TNPs) as photoanodes connected in series. The underlying concept of patterning the TNP of a few micrometers thick lies on the combination of the lift-off process of transfer-printed patterns of a sacrificial layer and the soft-cure ...

background and aims. clinical studies on dimensional changes of supraosseous gingiva (sog) following crown lengthening surgery have yielded different results. the aim of the present study was to evaluate the alterations in sog dimension following crown lengthening surgery. materials and methods. this clinical study included 20 patients with 20 teeth needing surgical exposure for proper restorat...

Structurally unrelated neural inducers in vertebrate and invertebrate embryos have been proposed to function by binding to BMP4 or Dpp, respectively, and preventing these homologous signals from activating their receptor(s). In this study, we investigate the functions of various forms of the Drosophila Sog protein using the discriminating assay of Drosophila wing development. We find that misex...

The Drosophila tolloid (tld) and tolloid related (tlr) gene products belong to a family of developmentally important proteases that includes Bone Morphogenetic Protein 1 (Bmp1). Tld is required early in Drosophila development for proper patterning of dorsal embryonic structures, whereas Tlr is required later during larval and pupal stages of development. The major function of Tld is to augment ...
