Standard treatment of cerebral alveolar hydatid disease consists of open brain surgery and systemic albendazole. We describe a patient with inoperable cerebral alveolar hydatid cysts on whom gamma knife radiosurgery was used instead of open brain surgery. Because of the size of the multicystic lesion, the gamma knife procedure was done in two sessions. Repeated courses of albendazole were given...

Vestibular schwannomas are common, and gamma knife radiosurgery is a treatment option of symptomatic tumors. Hydrocephalus may be a complication of gamma knife treatment of vestibular schwannoma, though the cause-and-effect relationship can be debated because tumors can cause hydrocephalus without treatment. We present an MR imaging study of an unusual case of communicating hydrocephalus after ...

A linear knife grid device was developed for first-stage size reduction of high- and low-moisture switchgrass (Panicum virgatum L.), a tough, fibrous perennial grass being considered as a feedstock for bioenergy. The size reduction is by a shearing action accomplished by forcing a thick packed bed of biomass against a grid of sharp knives. The system is used commercially for slicing forages for...

This paper proposes a cake-cutting protocol using cryptography when the cake is a heterogeneous good that is represented by an interval on a real line. Although the Dubins-Spanier moving-knife protocol with one knife achieves simple fairness, all players must execute the protocol synchronously. Thus, the protocol cannot be executed on asynchronous networks such as the Internet. We show that the...

OBJECTIVE Evaluate the efficiency and safety of bipolar plasma vaporization using plasma-cutting and plasma-loop electrodes for the treatment of posterior urethral stricture. Compare the outcomes following bipolar plasma vaporization with conventional cold-knife urethrotomy. METHODS A randomized trial was performed to compare patient outcomes from the bipolar and cold-knife groups. All patien...

We have successfully operated enucleation of oocyte by using microelectric knife without any thermal collateral damage. Minimally-invasive cellular-scale ablation was achieved by the mono-dispersed microbubbles which were generated by a pulse discharge of microelectrode. The discharged output power and conductive area of microelectrode were controlled by glass shell insulation around the copper...

The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 [1] and by King and Pennel in the United States in 1964 [2]. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded...

background & aim: a herbarium is a collection of preserved plant specimens. herbarium specimens form an important recorded of what plants grew where over time. kerman province with area about 171993 km2 has a lat of difference vegetation because of climatic and topography variations. it has different elevation (above sea level) from 300 m in shahdad to 4420 m in hezar mountains. material &...

Emergency Department, complaining of exertional dyspnea. A review of his medical history revealed that 3 years earlier he had tried to swallow a knife. It was removed from the esophagus by endoscopy. Two years before admission he told his relatives that he had swallowed another knife, but they did not believe him. Posteroanterior (Fig. 1) and lateral (Fig. 2) views of the chest were obtained, d...

We report a patient with medically refractory mesial temporal lobe epilepsy treated by gamma knife radiosurgery. In lieu of a microsurgical procedure, an entorhinoamygdalohippocampectomy was performed with a gamma knife and low marginal doses (25 Gy). The clinical and imaging studies, including CT, MR imaging, 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), and long-term follow-u...
