adsorption capacity of cr (vi) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, ph, temperature, agitation speed, absorbent dose and particle size. cr (vi) removal is ph dependent and found to be maximum at ph 2.0. the amounts of cr (vi) adsorbed increased with increase...

BACKGROUND Hardware removals are among the most commonly performed surgical procedures worldwide. Current literature offers little data concerning postoperative patient satisfaction. The purpose of our study was to evaluate the patients' point of view on implant removal. METHODS We surveyed patients of a German level one trauma center, who underwent hardware removal in 2009 and 2010, with reg...

National Hunt jockeys suffer a disproportionate number of clavicular fractures and their return to riding may be considerably delayed by refracture and symptomatic nonunion, with obvious implications. We report six such cases in which excision of the clavicular fragment distal to the fracture was associated with an early return to work and no recurrent injury to the shoulder.

The oxidation of D-lactobionic acid by Cr(VI) yields the 2-ketoaldobionic acid and Cr(3+) as final products when a 20-times or higher excess of the aldobionic acid over Cr(VI) is used. The redox reaction takes place through a complex multistep mechanism, which involves the formation of intermediate Cr(IV) and Cr(V) species. Cr(IV) reacts with lactobionic acid much faster than Cr(V) and Cr(VI) d...

The purpose of this study was to compare outcomes and complications of clavicular hook plate and Kirschner tension band wiring for fixation of unstable lateral clavicle fractures. The surgical outcomes of 92 consecutive patients (mean age, 49.30 ± 15.54 years) with unstable fractures of the lateral clavicle treated using AO clavicle hook plates were compared with those of 24 patients (mean age,...

background: the management of deep carious lesions can be done by various techniques but residual caries dilemma still persists and bacterial reduction in cavities treated by either partial or complete caries removal techniques is debatable. so the objective of the present randomized clinical trial was to compare microbial counts in cavities submitted to complete caries removal and partial cari...

background:  the purpose of this study was to report the preoperative complaints and postoperative outcome of patients after removal of the radial head prosthesis.   methods:  this is a retrospective review of 14 adult patients (6 females and 8 males) from 2007 to 2011, who underwent radial head prosthesis removal by three surgeons. the average time between implantation and removal was 23 month...
