The development of plant-based photocatalyst with a minimum time of irradiation for water-soluble dye disposal from industries is a great significance to unravel water pollution. In the present work, the sol-gel synthesis method was employed for the synthesis of zinc oxide nanoparticles using Pluronic F127 and Aloe vera as dispersing media. A hexagonal wurtzite structure and surface morphology confirmed by XRD and FE-SEM analysis. The infrared study was applied to substantiate the acceptable compounds within the nanoparticles and phytochemicals presence within the extract. From the DRS spectra, Bandgap energy of ZnO nanoparticles (3.22eV) was decreased to 2.89eV by blending of Aloe vera and Pluronic F127 into ZnO. The photocatalytic action of different combinations of ZnO was examined against malachite green dye under UV light and visible light irradiation. Upto 95% degradation was achieved for ZnO/Aloe/PF127 with a minimum time of UV light exposure. All combinations of ZnO showed effective bactericidal activity against multi-drug resistance of E.coli, S.aureus, B.subtilis, and P.aeruginosa. These findings proved the overwhelming photocatalytic and antibacterial activity of ZnO samples, which might be used as effective remediation to treat textile dye wastewater.

Objective To compare the effects of single doses of oral levodopa, subcutaneous apomorphine and sublingual apomorphine. Design Single-blind placebo-controlled comparative study. Setting Subjects were admitted as day patients to the neurology ward. Patients Five patients with idiopathic Parkinson's disease and "end of dose deterioration" entered and completed the study. Interventions Patients were given domperidone (20 mg by mouth three times a day) to prevent nausea and apomorphine (1-3 mg by subcutaneous injection), apomorphine in glycerol (10-30 mg sublingually) or their usual levodopa regimen. Main outcome measures Efficacy, time to onset of effect and duration of effect of oral levodopa, subcutaneous apomorphine and sublingual apomorphine. Tremor amplitude and timed pegboard and gait tasks were used as objective indices of clinical state. Results Maximal efficacy of the three treatments was comparable (P = 0.28-0.99). Mean latency to onset of effect of both formulations of apomorphine was less than that of levodopa (P = 0.022-0.048) but so was the duration of effect (P = 0.044-0.049). Conclusions Sublingual apomorphine may be a convenient means of rapidly terminating "off" periods associated with long term levodopa therapy.
