Previous investigations in male Macropodus showed that simultaneous bilateral removal of the telencephalon results in decreased sexual and nest-building behavior. The current investigation was to determine whether serial unilateral ablation of the telencephalic hemispheres, increased recovery time following simultaneous ablation, or prior spawning experience can produce savings in reproductive ...

To study the effects of laser fluence (laser energy density), scanning line spacing and ablation depth on the efficiency of a femtosecond laser for three-dimensional ablation of enamel and dentin. A diode-pumped, thin-disk femtosecond laser (wavelength 1025 nm, pulse width 400 fs) was used for the ablation of enamel and dentin. The laser spot was guided in a series of overlapping parallel lines...

Objective: To evaluate therapy effects and capability to preserve adjacent tissues of bilateral focal prostate ablation using Nd: YAG laser a canine model. Methods: 24 male Beagle dogs aged 3.9-7.4 years and weighting 9.4-12.1 kg were used in this study. The dogs underwent single focal Nd: YAG ablation. Applied the reasonable prostatic ablation parameters screened in the study and set different...

During the last decade laser processing of polymers has become an impoxtant field of applied and fundamental research. One of the most promising proposal, to use laser ablation as dry etching technique in photolithography, has not yet becume an industrial application. Many disadvantages of laser ablation, compared to conventional photolithography, are the result of the use of standard polymers....

OBJECTIVE Dosimetry studies have shown that activities of 131I as small as 10-20 MBq may cause a stunning effect. A result of this stunning effect may be a lower success rate of the ablative 131I therapy for differentiated thyroid carcinoma (DTC). The aim of this study was to determine whether pre-therapeutic uptake measurement with 40 MBq 131I causes a lower success rate of ablation. DESIGN ...

PURPOSE To identify an optimal customized ablation strategy in the treatment of eyes with secondary irregular astigmatism. METHODS Corneal anterior surface elevation maps of 50 eyes with secondary irregular astigmatism after decentered laser in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK) and 50 virgin eyes were used for customized ablation simulations. Two ablation simula...

OBJECTIVE To determine the approach that pediatric electrophysiologists use as they evaluate asymptomatic patients with Wolff-Parkinson-White (WPW) syndrome regarding electrophysiologic testing and radio frequency ablation. METHODS A 21-question survey was mailed to 66 pediatric electrophysiologists who had voluntarily submitted patient data at any time to the Pediatric Radio Frequency Ablati...

BACKGROUND Radiofrequency ablation (RFA) from the epicardial space for ventricular arrhythmias is limited or impossible in some cases. Reasons for epicardial ablation failure and the effect on outcome have not been systematically analyzed. METHODS AND RESULTS We assessed reasons for epicardial RFA failure relative to the anatomic target area and the type of heart disease and assessed the effe...

An ablation planning system plays a pivotal role in tumor ablation procedures, as it provides a dry run to guide the surgeons in a complicated anatomical environment. Over-ablation, over-perforation or under-ablation may result in complications during the treatments. An optimal solution is desired to have complete tumor coverage with minimal invasiveness, including minimal number of ablations a...
