The unique optical characteristics of a gold nanoshell motivate the application of nanoshell-based hyperthermia in drug delivery and cancer treatment. However, most of our understanding on energy absorption and heat transfer is still focused on individual particles, which may not be accurate for nanoshell aggregates in a real application due to the strong(More)
The aim of this study was to elucidate the regulatory role of androgen in the follicular development of wild female ground squirrels. Immunohistochemical staining of FSHR, LHR, P450c17, P450arom, androgen receptor (AR), estrogen receptors (ERa and ERb) were executed in ovaries of female ground squirrels from both breeding and nonbreeding seasons. In(More)
The aim of this study was to investigate the presence of nerve growth factor (NGF) and its receptors tyrosine kinase A (TrkA) and p75 in the ovaries of the wild ground squirrels during the breeding and nonbreeding seasons. In the breeding period, NGF, TrkA and p75 were immunolocalized in granulosa cells, thecal cells, interstitial cells and luteal cells(More)
Gold-nanoparticle-based hyperthermia has attracted considerable attention in the recent ten years in cancer treatment. In hyperthermia-based cancer treatment, in order to produce efficient thermal therapy yet without excessive heat damage to human body, besides the steady-state thermal condition, the transient thermal response is of vital importance. As(More)
—This paper aims to address the transient phenomenon in pulsed-laser-induced heating for nanoshell-based hyperther-mia. Within the framework of dual phase lag model, the transient temperature with the relaxation behavior involved was compared with that based on Fourier's law. The temporal variation of temperature is investigated under the irradiation of(More)
—The optical spectra and near-field enhancement of a multilayered gold nanoshell were theoretically studied in this paper to explore its potential biological applications. The mathematical model was developed within the framework of multipole expansion of a multilayered concentric sphere. Results show that compared with a conventional single-layered Au–SiO(More)
The practical application of the one-dimension hindered-compression settling models remains a challenge, since the model calibration strongly depends on experimental observations with limited information. In this study, the identifiability of parameter subsets of the hindered-compression models is evaluated for various experimental layouts. Global(More)
EC8871 aims to provide basic training and knowledge to students who consider international trade as one of their research fields. I attempt to strike a balance between the " extensive " and the " intensive " margins of course materials: extensive margin refers to an overview of various topics in this field, while intensive margin means technical training on(More)
