Photocatalytic degradation of organic dyes by mesoporous nanocrystalline anatase

A Clinical Comparative Study between Fentanyl and Dexmeditomidine as an Adjuvant with 0.75% Ropivacaine in Epidural Anaesthesia for Lower Limb Orthopaedic Surgery

“…Table 21 shows the spo2 of both the groups. Appropriate statistical test shows that there was no significant difference in the above parameter in the two study groups, which corroborates with the findings of Oriol Lopez SA et al 15 , J. Carreon, et al 7 , Bajwaet al 8 , Yongxin Liang, et al 19 , Selim MF et al 2 , Gupta et al 9 , Negi S et al 14 and Bamne et al 16…”

“…They found that the degree of sedation was less in patients receiving epidural fentanyl which corroborates with our findings. Also Carreon J et al 7 in their study found that higher ramsay scores were evident after giving epidural injection of dexmedetomidine when compared with fentanyl.…”

“…Similar to our study Salgado PFS et al 5 (2008), found in their study that epidural dexmedetomidine with 0.75% ropivacaine prolonged the motor block duration time and also resulted in a more intense motor block. Also Carreon Jet al 7 in their study comparing dexmedetomidine and fentanyl as adjuvants in epidural anaesthesia for open elective abdominal surgery concluded that there was no significant differences between Dexmedetomidine and Fentanyl when compared in terms of motor blockade, when administered in the epidural space. This is in contrast to our study, and the reason for that may be due to the higher doses of fentanyl 100mcg/kg taken for their study in comparison to our study which was 1mcg/kg fentanyl.…”

“…Similar to our study, Oriol Lopez SA et al 15 in their study found that after epidural blockade with dexmedetomidine 1mcg/kg to local anaesthesia, produces hemodynamic stability. J. Carreon, et al 7 in their study compared the adjuvants effects of epidural dexmedetomidine 1mcg/kg and fentanyl 100mcg/kg with local anesthesia for open elective abdominal surgery and found that the mean heart rate was lower in the dexmedetomidine group that needed treatment with atropine in comparison to the fentanyl group. But in contrast to it, in our study we found that the mean heart rate declined in both the groups at 30-50 mins that did not needed treatment with atropine except a very few patients in both the groups which was not statistically significant.…”

Oxidation of 4-Chlorophenol by Mesoporous Titania: Effect of Surface Morphological Characteristics

“…The slow coassembly between the inorganic network and the liquid crystalline phase leads to the formation of long-range order of well-defined mesostructures. The preparation of mesoporous titania particles by EISA has been studied by independent research groups [10][11][12][13]. It is expected that a change in size, shape, and dimensions of the mesopore TiO 2 modifies the accessibility, adsorption, and diffusion of guest molecules within the pore network, thereby achieving further degradation.…”
