Chemistry of phenolic stains in Douglas-fir sapwood

Creator:: Song, Hong-keun
Abstract:: Dihydroquercetin [(2,3-trans)-3,3',4',5,7-pentahydroxyflavanonol] was shown to be the precursor to the phenolic stains that often develop in Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] sapwood. Douglas-fir sapwood was extracted with methanol and the methanol solubles were fractionated by solvent partition, thin-layer chromatography, silica-gel column chromatography, and Sephadex gelpermeation chromatography. Tyrosinase, a commercially available...

The genetic dissection of the fruitless gene's functions during embryogenesis in Drosophila melanogaster

Creator:: Song, Ho-Juhn
Abstract:: The fruitless (fru) gene in Drosophila melanogaster is a multifunctional gene having sex-specific functions in the regulation of male sexual behavior and sex-nonspecific functions affecting adult viability and external morphology. While much attention has focused on fru's sex-specific roles, little is known about its sex-nonspecific functions. The embryonic central nervous...

Multifunctional Nanomedicine Platform for Concurrent Delivery of Chemotherapeutic Drugs and Mild Hyperthermia to Ovarian Cancer Cells

Creator:: Taratula, Olena, Dani, Raj Kumar, Schumann, Canan, Xu, Hong, Wang, Andrew, Song, Han, Dhagat, Pallavi, and Taratula, Oleh
Abstract:: A multifunctional tumor-targeting delivery system was developed and evaluated for an efficient treatment of drug-resistant ovarian cancer by combinatorial therapeutic modality based on chemotherapy and mild hyperthermia. The engineered iron oxide nanoparticle (IONPs)-based nanocarrier served as an efficient delivery vehicle for doxorubicin and provided the ability to heat cancer cells...

Air-sea interaction over ocean fronts and eddies

Creator:: Small, R. J., de Szoeke, Simon P., Xie, S. P., O'Neill, L., Seo, H., Song, Q., Cornillon, P., Spall, M., and Minobe, S.
Abstract:: Air-sea interaction at ocean fronts and eddies exhibits positive correlation between sea surface temperature (SST), wind speed, and heat fluxes out of the ocean, indicating that the ocean is forcing the atmosphere. This contrasts with larger scale climate modes where the negative correlations suggest that the atmosphere is driving the...

Methane flux of miniseepage in mud volcanoes of SW Taiwan: Comparison with the data from Europe and Azerbaijan

Creator:: Hong, Wei-Li, Etiope, Giuseppe, Yang, Tsanyao Frank, and Chang, Ping-Yu
Abstract:: Mud volcanoes (MVs) are considered as important methane (CH₄) sources for the atmosphere; gas is not only released from macroseepage, i.e., from craters and visible gas bubbling manifestations, but also from invisible and pervasive exhalation from the ground, named miniseepage. CH₄ flux related to miniseepage was measured only in a...

High-Contrast Imaging of Graphene via Time-Domain Terahertz Spectroscopy

Creator:: Tomaino, J. L., Jameson, A. D., Paul, M. J., Kevek, J. W., van der Zande, A. M., Barton, R. A., Choi, H., McEuen, P. L., Minot, E. D., and Lee, Yun-Shik
Abstract:: We demonstrate terahertz (THz) imaging and spectroscopy of single-layer graphene deposited on an intrinsic Si substrate using THz time-domain spectroscopy. A single-cycle THz pulse undergoes multiple internal reflections within the Si substrate, and the THz absorption by the graphene layer accumulates through the multiple interactions with the graphene/Si interface. We...

Transcriptional Regulation and Increased Production of Asukamycin in Engineered Streptomyces nodosus subsp. asukaensis Strains

Creator:: Xie, Pengfei, Sheng, Yan, Ito, Takuya, and Mahmud, Taifo
Abstract:: Asukamycin, a member of the manumycin family of antibiotics, exhibits strong antibacterial, antifungal, and anti-neoplastic activities. However, its production in the wild-type strain of Streptomyces nodosus subsp. asukaensis ATCC 29757 is relatively low. Recently, the biosynthetic gene cluster for asukamycin was identified in the producing organism and among the 36...

Modeling the Atmospheric Boundary Layer Wind Response to Mesoscale Sea Surface Temperature Perturbations

Creator:: Perlin, Natalie, de Szoeke, Simon P., Chelton, Dudley B., Samelson, Roger M., Skyllingstad, Eric D., and O'Neill, Larry W.
Abstract:: The wind speed response to mesoscale SST variability is investigated over the Agulhas Return Current region of the Southern Ocean using the Weather Research and Forecasting (WRF) Model and the U.S. Navy Coupled Ocean–Atmosphere Mesoscale Prediction System (COAMPS) atmospheric model. The SST-induced wind response is assessed from eight simulations with...

Creator:: Jackson, Allyson K., Evers, David C., Adams, Evan M., and et al.
Abstract:: Mercury (Hg) is a globally distributed environmental contaminant with a variety of deleterious effects in fish, wildlife, and humans. Breeding songbirds may be useful sentinels for Hg across diverse habitats because they can be effectively sampled, have well-defined and small territories, and can integrate pollutant exposure over time and space....
