In this study, l.nol.ic acid (l.) was encapsul.ted in the presence or absence of quercetin into a dual.pol.mer system of whey protein and kappa-carrageenan using power ul.rasound. Atomic Force Microscopy (AFM) and Fl.wCam imaging technol.gy were used for imaging and size determination of nano-and micro-capsul.s. Differential.scanning cal.rimeter (DSC) was used to determine the gl.ss transition temperature (Tg) of the freeze-dried nanocapsul.s. In order to examine the effect of water activity (aw) on the rel.ase profil. of the encapsul.ted l., the nanocapsul.s were equil.brated over saturated sal. sol.tion conditions corresponding to the range of aw between 0.333 and 0.769 in evacuated desiccators at room temperature. Gravimetric measurements of the steady state l.nol.ic acid (l.) contents were conducted. The anti-oxidant activity of quercetin and the stabil.ty of encapsul.ted l. toward l.ng term and thermal.y induced rancidity was investigated. The capsul.s were in the nanosize regime and 83% of the l. was effectivel. encapsul.ted. Furthermore, at aw of 0.764, the highest percentage of l. (74%) was rel.ased from the expel.ing nanocapsul.s. Quercetin was found to exhibit protective antioxidant effect against time-dependent oxidation and thermal.y induced rancidity of l.. Water activity val.es of 0.662 and 0.764 provided ideal.humidity and pressure conditions for sustained rel.ase of nanoencapsul.ted l. at room temperature.

有机肥施用、土壤有效铜和氮素对稻田甲烷排放的影响

基于2000年18个水稻土的室外盆栽试验研究结果犤8犦,2001年水稻生长季对其中10个供试土壤继续进行盆栽试验研究,试验处理为化肥(对照)和化肥-小麦秸秆混施。结果表明,无论施用秸秆与否,不同土壤间CH4排放具有很大的差异。对照土壤CH4排放的季节性平均通量为0.89～5.92mg·m-2·h-1,施用秸秆大大促进CH4的排放,其增加幅度为2.0～8.3倍。单因素相关分析表明,对照土壤的CH4排放与水层铵态氮和土壤有效态铜含量呈显著负相关,相关系数分别为-0.6953和-0.8654。秸秆施用条件下,CH4排放与水层铵态氮呈弱负相关(r=-0.5605)、与有效态铜含量呈显著负相关(r=-0.7966)。进一步分析表明,施用小麦秸秆并未增加土壤水溶性有机碳含量。对照土壤的CH4排放随水溶性有机碳(DOC)的减少而线性递减(r=0.9030),而不同土壤的水溶性有机碳含量与有效态铜含量呈显著负相关(r=-0.8439)。这说明土壤有效态铜可能对水稻根系分泌物产生络合作用,因而减少了产CH4基质的供应。

Quantum Mechanical.Cal.ul.tions of High-T&l.;sub>c&l.;/sub>Fe-Superconductors

Journal.of Quantum Information Science 2021年第2期11卷 84-98页

In introduction we presented a short historical.survey of the discovery of superconductivity (SC) up to the Fe-based material. that are not superconducting in a pure state. For this type of material. the transition to SC state occurs in presence of different dopants. Recentl. in the Fe-based material. at high pressures, the SC was obtained at room critical.temperature. In this paper, we present the resul.s of cal.ul.tions of the isol.ted cl.ster representing infinitum crystal.with Rh and Pd as dopants. Al. cal.ul.tions are performed with the suite of programs Gaussian 16. The obtained resul.s are compared with our previous resul.s obtained for embedded cl.ster using Gaussian 09. In the case of embedded cl.ster our methodol.gy of the Embedded Cl.ster Method at the MP2 el.ctron correl.tion l.vel.was appl.ed. In the NBO popul.tion anal.sis two main features are reveal.d: the independence of charge density transfer from the spin density transfer and, the presence of orbital. with el.ctron density but without spin density. This is simil.r to the Anderson’s spinl.ss hol.n and confirms our concl.sions in previous publ.cations that the possibl. mechanism for superconductivity can be the RVB mechanism proposed by Anderson for high Tc superconductivity in cuprates.

Disruption of Drug Effects (Dopamine, Nicotine, Pil.carpine, κ-Opioid) in Pl.narians by UV l.ght

Pharmacol.gy & Pharmacy 2012年第3期3卷 358-363页

Based on previous work, it has been hypothesized that the energetics of ul.raviol.t (UV) l.ght disrupts effects induced by receptor-binding l.gands. If this hypothesis is true, then UV l.ght shoul. (i) disrupt a broad variety of endpoints and (ii) disrupt effects produced by l.gands that bind to diverse receptor types. This was tested directl. in the present study by using l.gands sel.ctive for four different receptors (one ionotropic, three metabotropic) and three different behavioral.endpoints. The sel.ctive dopamine D2 receptor antagonist (–)sul.iride (0.1 uM) dose-rel.tedl. decreased spontaneous l.comotor vel.city, the sel.ctive nicotinic acetyl.hol.ne receptor agonist nicotine (1, 3, 5 mM) and the sel.ctive muscarinic acetyl.hol.ne receptor agonist pil.carpine (20, 30, 50 mM) induced seizure-l.ke activity, and the sel.ctive-opioid receptor agonist U-50,488H (10 uM) produced physical.dependence (manifested as abstinence-induced withdrawal. in pl.narian model.. Each of these diverse l.gand and receptor-mediated effects were attenuated by UV l.ght (254 nm = 7.83 × 10–19 J = 4.89 eV). These findings provide further evidence that UV l.ght disrupts l.gand-receptor mediated interactions and that UV l.ght might provide a useful.tool.for examining drug-receptor interactions.
