Research ArticleOpen accessIn the author namesUltrasonic Study and Physical Properties of Borotellurite GlassesW.M. Daud, H. Zainul, Z.A. Talib et al.A series of glasses (TeO2)x (B2O3)1-x with x = 0.6, 0.63, 0.65, 0.70, 0.73, 0.75, 0.78 and 0.80 were synthesized by rapid quenching. Longitudinal and shear ultrasonic velocity were measured at room temperature and at 5 MHz frequency. Elastic properties, Poisson’s ratio and micro hardness have been calculated from the measured density and ultrasonic velocity at room temperature. Estimated parameters … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,912 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Flavonoid, Quercetin, Inhibits HIV-1 Infection in Normal Peripheral Blood Mononuclear CellsMadhavan P.N. Nair, Zainulabedin M. Saiyed, Nimisha H. Gandhi, C. N. RamchandProblem statement: Flavonoids and related polyphenols, have been known to possess cardioprotective, anti-tumor, anti-inflammatory, anti-allergic and anti-viral activities. Previous studies have shown that flavonoid, quercetin significantly downregulates expression of pro-inflammatory cytokines in cultured cells via modulation of NFκB and p38MAPK signaling pathways. In the current study, we hypothesize that quercetin exerts anti-HIV activity by differential modulation of pro-and anti-inflammatory cytokine … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 12,190 accessesView PDFCite
