BACKGROUND Despite surgical and technical advances in microsurgery, it is still difficult to obtain satisfactory results after replantation of finger amputation. The aim of the present study was to discuss some of the many factors that can affect the success rate of replantation. METHODS A retrospective analysis of 60 patients with 85 finger replantations was performed. Revascularizations and...

The stress induced in animals due to handling prior to sacrifice has been shown to produce changes in total acetylcholine (Ach) content of the brain and heart of adult rats. Two methods of killing the animals were compared viz. cervical dislocation and decapitation by a guillotine technique; the former method producing more handling stress than the latter. Ach levels were significantly lower bo...

THE sequence nitrous oxide-oxygen-ethyl chloride is one which has been successfully used by a number of anaesthetists for many years, especially when a pleasant induction followed by brief but deep anaesthesia and rapid recovery, is desired—e.g. for guillotine tonsillectomy in children. The accompanying photograph illustrates an improvisation to a standard Boyle machine with a Magill attachment...

We describe in this paper a context-free grammar, with parameters, that generate models for covering a rectangular area with many smaller rectangular pieces. The generated language contains all the models that can be generated using only guillotine restrictions. The grammar was inspired by the practical problem of covering a rectangular room with carpet or linoleum. The source of rectangular pi...

The concentration of 5-hydroxytryptamine (5-HT, Serotonin) varies as a result of physiological changes in the availability of its precursor tryptophan to the serotonergic neurons in the brain. Increase in brain tryptophan occurs following an increase in plasma tryptophan concentration. Tryptophan intake increases brain serotonin metabolism and enhances memory. The Present study was designed to ...

Abstract Numerical modeling of the outflow an air jet into water with a guillotine rupture pipeline by VOF method using k-ε and k-ω SST turbulence models was carried out. The calculations were out in axisymmetric approximation. following phases process calculated: formation large gas bubble at place rupture, its growth, separation from behind bubble. It is shown that rate detachment model highe...
