将棕榈叶在惰性气氛中经一步热解过程制备出多孔炭(NPCs),并结合香豆素-6(C-6)形成NPCs-C-6复合荧光染料来进行癌细胞成像及靶向给药。通过XRD和Raman分析可知,NPCs具有高的含碳量。傅里叶红外分析表明棕榈叶中含有纤维素、半纤维素和木质素,这有利于NPCs的形成,以及香豆素-6为导航分子的细胞成像和靶向给药。采用SEM和TEM观察NPCs结合前后的结构形貌,XPS表征元素组成。采用Zeta电位为初始指标来确定颗粒分散质量,以适合生物医学应用。NPCs-C-6分析细胞毒性和成像试验表明,对正常细胞系(MDCK:ATCCCCL-34^(TM))有高的生物相溶性,对人体癌细胞系(A-375∶ATCCCRL-1619TM与N2A∶ATCCCCL-131^(TM))有高的毒性。因此,这些研究结果有望为生物基功能NPCs作治疗载体的研究进展提供新思路。

Background:In China, the prevalence of allergic rhinitis (AR) and asthma has increased in the past decade. As these two diseases frequently coexist, the Asia-Pacific Survey of Physicians on Asthma and Allergic Rhinitis (ASPAIR) study aimed to assess physicians5 beliefs and treatment patterns of coexistent asthma-AR across six Asian countries. This analysis presents the results from China. Methods: The 200 hospital-based general physicians and pediatricians were interviewed from five cities in China. Physicians were questioned in-person about their knowledge, beliefs and management practices for patients with coexistent asthma-AR. Results: Approximately 70% of the physicians interviewed routinely evaluated their patients with asthma or AR for signs of coexistent disease. While the majority of physicians (>90% of physicians) recognized the increased burden of coexistent asthma-AR vs. one condition alone and that coexistent disease requires additional treatment, most physicians (96%) also believed that patients with coexistent asthma-AR were well managed if either condition alone improved. Similarly, although 71% of physicians selected a combination of intranasal and inhaled corticosteroids as their preferred treatment for coexistent asthma-AR, in line with treatment guidelines, two fifths of physicians indicated that treatment for coexistent disease requires too much medication and that their patients prefer oral medications and a third of physicians believed that corticosteroids should be delayed in children. Conclusions: This survey demonstrates that physicians interviewed in China have a broad understanding of coexistent asthma-AR and its impact on patients. A holistic approach to patient management with informed decisions regarding patients' overall treatment will benefit patients who suffer from coexistent disease.

Low cost, high performance supercapacitor electrodes were fabricated using coconut waste as precursor. Simple one step pyrolysis is adopted to get the spherical shaped particle where lignocellulosic nature of carbon converts into porous carbon nanospheres. Three types of coconut wastes, namely, coconut fiber(CF), coconut leaves(CL) and coconut stick(CS) have been studied and compared for their application in supercapacitors. Uniform spherical shape with particle size ranging from 30 to 60 nm for leaves and sticks and20 nm for fibers was obtained. The electrochemical properties of the porous carbon nanospheres were studied using cyclic voltammetry(CV), chronopotentiometry(CP) and electrochemical impedance spectroscopy(EIS). The porous carbon nanospheres derived from all the three biowaste samples show good electrochemical performance for supercapacitor application. Porous carbon nanospheres derived from coconut fiber exhibited maximum specific capacitance of 236 F/g followed by coconut stick and coconut leaves with 208 and 116 F/g respectively at a scan rate of 2 m V/s. Further impedance studies showed a charge transfer resistance of 4.9 for the porous carbon nanospheres derived from coconut fiber, while those from coconut leaves and coconut stick exhibited a slightly higher resistance of 6 and14.2, respectively. The simple eco-friendly approach we have demonstrated for synthesizing coconut waste based carbon nanospheres makes them excellent candidates for future, low-cost, energy storage devices.
