Agrobacterium rhizogenes-mediated transformation has become a powerful tool for studying gene function and root biology due to its quick and simple methodology. This transformation method is particularly suitable for those plants, including legumes, whose transformation using Agrobacterium tumefaciens has been challenging. Although there are some reports on(More)
Overabundance of hydrogen peroxide originating from environmental stress and/or genetic mutation can lead to pathological conditions. Thus, the highly sensitive detection of H2 O2 is important. Herein, supramolecular fluorescent nanoparticles self-assembled from fluorescein isothiocyanate modified β-cyclodextrin (FITC-β-CD)/rhodamine B modified ferrocene(More)
Whether rare earth elements can enter into plant cells remains controversial. This article discusses the ultracellular structural localization of lanthanum (La3+) and europium (Eu3+) in the intact plant cells fed by rare earth elements Eu3+ and La3+. Eu-TTA fluorescence analysis of the plasmalemma, cytoplast, and mitochondria showed that Eu3+ fluorescence(More)
A novel actinomycete, designated strain FXJ1.034(T), was isolated from acidic soil collected in Jiangxi Province, South-east China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain FXJ1.034(T) belonged to the genus Lentzea and showed high sequence similarities to Lentzea kentuckyensis NRRL B-24416(T) (98.5%) and Lentzea albida(More)
INTRODUCTION Glucosylceramide synthase (GCS) is one enzyme that provides a major route for ceramide clearance. Recent evidence has indicated an important role for GCS in multidrug resistance (MDR) tumors. Doxorubicin (DOX)can modulate the expression of GCS in leukemia and ovary cell lines. However, few studies have investigated their relationship in breast(More)
Novel biological carbon materials with highly ordered microstructure and large pore volume have caused great interest due to their multifunctional properties. Herein, we report the preparation of an interconnected porous carbon material by carbonizing the organic matrix of mollusc shell. The obtained three-dimensional carbon skeleton consists of hexangular(More)
BACKGROUND MicroRNAs (miRNAs) have been documented as playing important roles in diverse biological processes including tumorigenesis. However, the function and mechanism of miR-326 in gastric cancer are still unknown. The aim of this study is to identify the role of miR-326 in gastric cancer and clarify the regulation of Fascin1 (FSCN1) by miR-326. (More)
Tumor-to-tumor metastasis (TTM) is a rare phenomenon. We present a case of an invasive ductal carcinoma (IDC) of the breast metastasizing to a clear cell renal cell carcinoma (RCC). Breast cancer (BC) metastasis to the RCC is rarely reported, especially in resected kidney tumor. In several cases reported, IDC was the exclusively histologic type of BC(More)
A novel method using a fuzzy practicable interval to characterize non-statistical uncertainty in dynamic measurement is proposed. The method permits the uncertainty being estimated under the conditions that the number of measurements is very small and the probability distribution unknown. The feasibility of the method is validated by computer-simulation(More)
Highly branched poly(β-amino esters) (HPAEs) are developed via a facile and controllable "A2+B3/B2" strategy successfully. As nonviral gene delivery vectors, the performance of HPAEs is superior to the well-studied linear counterpart as well as the leading commercial reagent Superfect. When combined with minicircle DNA construct, HPAEs can achieve ultrahigh(More)
