An azobenzene-containing surfactant was synthesized for the phase transfer of α-cyclodextrin (α-CD)-capped gold nanoparticles between water and toluene phases by host-guest chemistry. With the use of the photoisomerization of azobenzene, the reversible phase transfer of gold nanoparticles was realized by irradiation with UV and visible light. Furthermore, the phase transfer scheme was applied f...

The photo-reversible [4πs+4πs] cycloaddition reaction of pendant anthracene moieties represents a convenient strategy to impart wavelength dependent properties into hydrogenated carboxylated nitrile butadiene rubber (HXNBR) networks. The present article provides the 1H NMR data on the reaction kinetics of the side chain functionalization of HXNBR. 2-(Anthracene-9-yl)oxirane with reactive epoxy ...

The mechanism of the SmI2 -mediated reduction of unactivated esters has been studied using a combination of kinetic, radical clocks and reactivity experiments. The kinetic data indicate that all reaction components (SmI2 , amine, H2 O) are involved in the rate equation and that electron transfer is facilitated by Brønsted base assisted deprotonation of water in the transition state. The use of ...

results all eight candida species were successfully detected, identified and quantitated based on the icl gene. a seven-log range of the gene copy number and a minimum detection limit of 103 copies were achieved. conclusions a one-tube absolute quantification real-time pcr that differentiates medically important candida species via individual unique melting temperature was achieved. analytical ...

We provide an analytic solution for diffusion-influenced geminate reaction with multiple (N) reversible binding sites (of which one may be irreversible). The solution obtained in the Laplace domain, for two different initial conditions, is valid for the case when the sites are overlapping spheres with no long-range interactions with the diffusing particle. The possibility to invert into the tim...

The kinetics of excited-state proton transfer to solvent from the strong photoacid 5-cyano-2-naphthol exhibits two different power-law asymptotic tails for acid and base, arising from competition between reversible and irreversible geminate reprotonation. We show that the data are in quantitative agreement with a recently developed theory for this diffusion-influenced reaction. q 2000 Elsevier ...

results the results showed that nl1-gc/ls2 primer set could yield species-specific amplicons, which were well distinguished and allowed better species discrimination than that generated by the its3-gc/its4 primer set, in both dgge and ttge profiles. all five candida species were discriminated by dgge and ttge using the nl1-gc/ls2 primer set. conclusions comparison of dgge and ttge profiles obta...

background aseptic meningitis is the most common type of meningitis and is characterized by meningeal inflammation that is not linked to identifiable bacterial pathogens in cerebrospinal fluid (csf). objectives this study aimed to evaluate the frequency of aseptic meningitis caused by herpesviruses, namely herpes simplex types i and ii (hsv-1, hsv-2), epstein-barr virus (ebv), cytomegalovirus (...

conclusions in the present study, the highest prevalence was for st5, which is so important for epidemiology and risk of human infection. the report related to st3 in cattle as a subtype of human showed mutual infection between human and cattle. another important point in this study was the st6 report. finally, it seems that gathering epidemiological data is needed for a better understanding of...

background toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. the parasite is able to infect all warm-blooded hosts including human.the infection occures via consumption of food or water containing oocytes, eatingundercooked meats containing tissue cysts, and placenta. undercooked meat consumption is one of the most important ways of toxoplasma transm...
