OBJECTIVE To evaluate the safety and efficacy of an 810-nm diode laser for treatment of benign oral soft tissue lesions. MATERIALS AND METHODS Treatment with the 810-nm diode laser was applied to a group of eighteen patients with pathological frenulum and epulis fissuratum; five patients with oral lichen planus, oral leukoplakia, and mucous membrane pemphigoid; and four patients with pyogenic...

PURPOSE Therapeutic retinal laser photocoagulation can damage the neurosensory retina and cause iatrogenic visual impairment. Subthreshold micropulse photocoagulation may decrease this risk by selective tissue treatment. The aim of this study was to compare subthreshold 810-nm diode micropulse laser and subthreshold 532-nm micropulse laser on the retina by histologic examination and differentia...

The newly developed QA-810V is an optional unit for the determination of five-part white blood cell differentials. It can be used together with the same manufacturer's haematology analyser which has been used in relatively small-sized laboratories. The present study evaluates the basic performance of the QA-810 V and the MEK-8118 haematology analyser using routinely obtained blood specimens tre...

Urinary recovery of intratracheally instilled polyethylene glycol polymers (PEG:s) in the molecular weight range 722-1294 Da (PEG 1000) was studied under normal conditions and during experimentally induced lung damage in rats. The urinary PEG recoveries were between 30-60% under normal conditions, with a selectivity for smaller PEG:s. No significant differences in the urinary PEG molecular weig...

At a recent conference (1) in Woods Hole, Massachusetts, investigators (2) met to discuss the nematode Caenorhabditis elegans. This free-living worm may, according to some workers, become the Escherichia coli or at least the bacteriophage T4 of the animal world. Small (about I mm in length) and semitransparent, C. elegans provides for research the advantages of a short life cycle (3 days) and a...

Sutureless end to end ureteral anastomoses was successfully constructed in acute and chronic experiments. A photothermal sensitive hydrolyzable (PSH) albumin stent played roles as solder and intraluminal supporter to adhesion and position the anastomosed ureter by end to end fashion. The anastomosis seam was lased with 810 nm diode laser energy supplied through hand-held 600 mm noncontact optic...
