Twenty-two different triazoles were prepared to examine the anti-Trichomonas vaginalis structure-activity relationships (SAR) within the β-lactam-isatin-triazole conjugate family. The compounds were synthesized by copper-catalyzed 'click chemistry.'In vitro activity against T. vaginalis was determined at 10 and 100 μM for each compound, with eighteen of the(More)
The study was designed to evaluate the influence of season on semen characteristics and seminal plasma protein profile of buffalo bull semen. Thirty-six ejaculates were collected in three seasons (winter, summer and rainy) from six adult Bhadawari bulls, and semen characteristics were evaluated immediately after collection. The seminal plasma was harvested(More)
BACKGROUND The nature of influenza viral shedding during naturally acquired infection is not well understood. METHODS A cohort study was conducted in Hutterite colonies in Alberta, Canada. Flocked nasal swabs were collected during 3 influenza seasons (2007-2008 to 2009-2010) from both symptomatic and asymptomatic individuals infected with influenza.(More)
3,4-Dihydroxyphenyl-L-alanine (L-DOPA)-induced dyskinesia (LID) is a debilitating side effect of long-term dopamine replacement therapy in Parkinson's Disease. At present, there are few therapeutic options for treatment of LID and mechanisms contributing to the development and maintenance of these drug-induced motor complications are not well understood. We(More)
3-Azido-, 3-amino- and 3-(1,2,3-triazol-1-yl)-β-lactams were synthesized and evaluated for their antiplasmodial activity against four strains of Plasmodium falciparum and KB cells for their cytotoxicity profiles. The presence of a cyclohexyl substituent at N-1 and a phenyl group on the triazole ring markedly improved the activity profiles of(More)
Ficus carica fiber based activated carbon (FCAC) was used as a potential adsorbent for Cr(VI) removal from aqueous system. The adsorbent was prepared by carbonization of F. carica fiber followed by H3PO4 activation under microwave radiations. The activated carbon was characterized using scanning electron microscopy and Fourier transformer infrared(More)
1,2,3-Triazole tethered β-lactam and 7-chloroquinoline bifunctional hybrids were synthesized and evaluated as potential antimalarial agents. Activity against cultured Plasmodium falciparum was dependent on the N-substituent of the β-lactam ring as well as the presence of bis-triazole at the C-3 position. The observed activity profiles were further(More)
Although the microneutralization (MN) assay has been shown to be more sensitive than the hemagglutination inhibition (HAI) assay for the measurement of humoral immunity against influenza viruses, further evidence relating MN titres to protective efficacy against infection is needed. Serum antibodies against seasonal H1N1 and H3N2 influenza were measured in(More)
The manuscript describes the synthesis of novel 1,2,3-triazole tethered β-lactam-chalcone bifunctional hybrids via click chemistry approach utilizing azide-alkyne cycloaddition reactions and their evaluation as anticancer agents against four human cancer cell lines. The presence of a cyclohexyl substituent at N-1 of β-lactam ring and methoxy substituents,(More)
