PURPOSE The purpose of this study was to investigate the optimal molecular weight of dispersive sodium hyaluronate (Na-HA) for the reduction of corneal endothelial damage induced by sonication, irrigation, and aspiration, using enucleated pig eyes. METHOD The phaco-needle of phacoemulsification and aspiration (PEA) equipment was inserted into the anterior chamber after aqueous humor replaceme...

The aim of this preliminary study was to verify the antibacterial potential of cetylpyridinium chloride (CPC) in root canals infected by Enterococcus faecalis. Forty human maxillary anterior teeth were prepared and inoculated with E. faecalis for 60 days. The teeth were randomly assigned to the following groups: 1: Root canal preparation (RCP) + 0.1% CPC with positive-pressure irrigation (PPI, ...

Abstract Many regions in Indonesia are suffering from a water crisis due to limited annual precipitation, especially dry regions, which affects agricultural production. Climate change is becoming more severe, threatening global food and security. Thus, the development of affordable irrigation for smallholder farms crucial increasing The study aims provide better design management small gravity ...

OBJECTIVE To determine the operative advantage in terms of minimizing the complications following conventional phaco surgery with dual infusion through irrigating chopper. METHODS A Randomized Controlled Clinical Trial (RCCT) was conducted in the Ophthalmology Unit-III, Sindh Government Lyari General Hospital and DUHS and Al-Noor Eye Hospital Karachi, from March 2008 to February 2009.

Sound irrigation and nitrogen management strategies are necessary to achieve sustainable yield water use efficiency of winter wheat in the North China Plain (NCP). The coupled effects scheduling application mode (NAM) on growth, under drip were evaluated with a two-year field experiment, which consisted three levels (ISLs) (irrigating when soil consumption (SWC) reached 20, 35 50 mm, referred a...

Isolated human and rabbit corneas were incubated in glutathione bicarbonate Ringer solution (GBR), balanced salt solution (BSS), or 0.9% NaCl solution. The swelling rate of human corneas was 25.5 micron/hr in GBR and significantly increased to 32.7 in BSS and 66.1 in NaCl. The epithelial intracellular potential of human cornea was constant at about 60 mV up to 5 hr of incubation in GBR and decr...
