W does it matter if someone can push himself to run another mile on a dreary February morning or stop himself from reading online sports news at work? In other words, what are the downstream consequences of self-regulation? A large body of research within personality, organizational, and social psychology has demonstrated that self-regulation has significant consequences for the individual. Goo...
A series of PPVO (p-phenylene vinylene oligomer) derivatives with functional groups of varying electronegativity were synthesized via the Horner-Wadsworth-Emmons reaction. Subtle changes in the end group functionality significantly impact the molecular electronic and optical properties of the PPVOs, resulting in broadly tunable and efficient UV absorption and photoluminescence spectra. Of parti...
All four stereoisomers (7-10) of ethyl undeca-2,4-dienoate were prepared in ≥ 98% isomeric purity by Pd-catalyzed alkenylation (Negishi coupling) using ethyl (E)- and (Z)-β-bromoacrylates. Although the stereoisomeric purity of the 2Z,4E-isomer (8) prepared by Suzuki coupling using conventional alkoxide and carbonate bases was ≤ 95%, as reported earlier, the use of CsF or (n)Bu(4)NF as a promote...
A sufficient dose of ultraviolet light (2,0537 A) inactivates most microorganisms. Exposure of inactivated cells to suitable visible light results in the recovery of a large portion of the cells from their otherwise fatal ultraviolet-induced injury. The discovery of light-induced recovery (Kelner, 1949) and its confirmation for bacteriophage by Dulbecco (1949) gives us fresh hope for solving th...
This study aims to explore residents’ attitudes toward tourism and how these attitudes could be influenced by factors such as of one’s subjective sense of well-being and personal satisfaction with life. The study’s empirical geographical context is Taormina, a Sicilian community with high touristic frequency. Taormina is a popular resort town in Sicily with many interesting sights and attractio...
Actinomycosis in the human being is a chronic, suppurative disease resulting from infection with the fungus Actinomyces bovis. Prior to the advent of the sulfonamides and later penicillin and streptomycin, the prognosis of patients suffering from actinomycotic infections was not too promising. There are many reports in the literature concerning the succesful use of penicillin as a chemotherapeu...
Three different series of phosphonate derivatives, b-aminoand fused thiadiazolo/thiadiazine-phosphonates have been synthesized using the addition and/or addition-cyclization protocol of Horner-Wadsworth-Emmons (HWE) reagents to 1,2,4-triazole-3-thiols. The design of potentially antimicrobial and anticancer phosphor esters relied on the results of computer-assisted molecular modeling. All synthe...
The synthesis of aliskiren (1), a recently marketed drug for the treatment of hypertension, is presented. The focus of our synthetic effort is to develop an efficient pathway for the synthesis of (2S,7R,E)-2-isopropyl-7-(4-methoxy-3-(3-methoxypropoxy) benzyl)-N,N,8-trimethylnon-4-enamide (2a), which has been used as the advanced intermediate toward aliskiren. After an extensive investigation of...
The ability to identify yeast isolates by the new enzymatic RapID Yeast Plus System was compared to the ability to identify yeast isolates by the API 20C system. A total of 447 yeast isolates representing Blastoschizomyces capitatus, 17 Candida spp., 5 Cryptococcus spp., Geotrichum spp., 2 Hanseniaspora spp., Hansenula anomala, Hansenula wingei, 3 Rhodotorula spp., Saccharomyces cerevisiae, Spo...
