Serenoa repens, the extract of berry in Southeastern United States, is one of several phytotherapeutic agents available for the treatment of Benign prostatic hyperplasia (BPH). In this study, we found for the first time that Serenoa repens effectively inhibited the growth of human U87 and U251 glioma cells. Flow cytometry assay showed that Serenoa repens(More)
The island growth mode of Pt was employed to guide the forma-tion of PdPt alloy nanodots on gold nanorods (Au@PdPt NRs). Well-defined alloy nanodots, with tunable Pd/Pt ratios from 0.2 to 5, distribute homogeneously on the surface of the Au NR. Formation of nanodots shell leads to the red-shift and broadening of the longitudinal surface plasmon resonance(More)
Nanostructured materials are a new class of enzyme mimics, the inhibitors of which have not been studied. Herein, we demonstrate the screening of inhibitors for Au@Pt nanorod (NR) oxidase mimics. In addition, based on the enzyme inhibition reaction, determination of "poisoning" inhibitors is demonstrated.
Serenoa repens, a palm species native to the Southeastern United States, is one of the widely used phytotherapeutic agents in benign prostatic hyperplasia. In this study, we found for the first time that Serenoa repens induced growth arrest of a variety of human leukemia cells including U266 and RPMI 8226 multiple myeloma cells as measured by(More)
The main research progress in core-shell noble metal nanostructures templated by gold nanorods (Au NRs) is summarized regarding synthesis, optical, and catalytic properties. Design and fabrication of core-shell hybrid nanostructures are demonstrated to be effective not only for optimizing and expanding intrinsic properties but also for creating novel(More)
We investigated the penetration and thermotherapy efficiency of different surface coated gold nanorods (Au NRs) in multicellular tumor spheroids. The current data show that negatively charged Au NRs, other than positively charged Au NRs, can penetrate deep into the tumor spheroids and achieve a significant thermal therapeutic benefit.
The objective of this study was to measure the related parameters of intercarotid artery (ICA) in the operative plane of endonasal transsphenoidal approach for hypophyseal surgeries. Nine parameters of the ICA were examined in the computed tomographic angiographic (CTA) scan of 101 patients. The shortest distance between the middle point of the nasal(More)
The inhibitors of BRAF and MEK targeting MAPK signaling pathway provide a comparatively effective therapeutic strategy for melanoma caused by BRAF mutation. However, melanoma, especially metastatic melanoma, has become one of the most threatening malignancies. Thus, the identification of exact molecular mechanisms and the key components involved in such(More)
We observed mitochondrial connexin43 (mtCx43) expression under cerebral ischemia-reperfusion (I/R) injury, analyzed its regulation, and explored its protective mechanisms. Wistar rats were divided into groups based on injections received before middle cerebral artery occlusion (MCAO). Cerebral infarction volume was detected by 2,3,5-triphenyltetrazolim(More)
High-temperature sensors are desirable for structural health monitoring and/or nondestructive evaluation of next-generation turbines, more efficient jet engines, and the furnace components of electrical power plants. Of all the investigated high-temperature piezoelectric materials, rare-earth calcium oxyborate crystals ReCa4O(BO3)3 (ReCOB, Re: rare-earth)(More)
