Tactics of surgical treatment of spondyloptosis including use of transpedicular external fixation device is presented. There were 4 patients with L5 spondyloptosis. The tactics is characterized by minor traumatization of lumbosacral spine with external fixation device, decrease of neurologic complications rate owing to gradual L5 reduction, possibility of spine deformity elimination, significant technical simplification of internal transpedicular osteosynthesis performance. Clinical results showed normalization of anatomic interrelation in lumbosacral spine, elimination of vertebroradicular conflict, restoration of trunk balance and anthropometric proportion as well as stabilization of L5-S1 segment by osteo-metalic block.

Technical Simplification

Determination of laser frequency with high resolution under continuous and abrupt tuning conditions is important for sensing, spectroscopy, and communications. We show that a single microresonator provides rapid and broadband measurement of optical frequencies with a relative frequency precision comparable to that of conventional dual-frequency comb systems. Dual-locked counterpropagating solitons having slightly different repetition rates were used to implement a vernier spectrometer, which enabled characterization of laser tuning rates as high as 10 terahertz per second, broadly step-tuned lasers, multiline laser spectra, and molecular absorption lines. Besides providing a considerable technical simplification through the dual-locked solitons and enhanced capability for measurement of arbitrarily tuned sources, our results reveal possibilities for chip-scale spectrometers that exceed the performance of tabletop grating and interferometer-based devices.

Technical Simplification

The suspension of cells from monolayer cultures for manometric measurements provides a technical simplification and has therefore become a frequent manipulation in such studies. In the experiments described respiration, aerobic glycolysis and lifespan of the cells after their transition from the intact cell-layer to the suspension were studied.The glycolytic rate remains unchanged in the suspension, if the culture medium was not changed. Cultures without glycolysis do not glycolyse in the suspension either.The respiratory rate is independant of glycolysis. Under the conditions used it is somewhat accelerated in cell-suspensions. The lifespan of the cells is considerably reduced. After 5 to 10 hrs. a distinct loss of respiratory rate can be noted, which does not take place in cell-layers.The reproducability of the results in cell suspensions is not sufficient.Considered in the light of these findings cell suspensions of monolayer cultures seem only conditionally suitable for manometric measurements and should only be used when measurements with intact cell-layers are not possible.

BACKGROUND: Patients presenting upper gastrointestinal obstruction, difficulty or inability in swallowing, may need nutritional support which can be obtained through gastrostomy and jejunostomy. AIM: To describe the methods of gastrostomy and jejunostomy video-assisted, and to compare surgical approaches for video-assisted laparoscopy and laparotomy in patients with advanced cancer of the esophagus and stomach, to establish enteral nutritional access. METHODS: Were used the video-assisted laparoscopic techniques for jejunostomy and gastrostomy and the same procedures performed by laparotomies. Comparatively, were analyzed the distribution of patients according to demographics, diagnosis and type of procedure. RESULTS: There were 36 jejunostomies (18 by laparotomy and 17 laparoscopy) and 42 gastrostomies (21 on each side). In jejunostomy, relevant data were operating time of 132 min vs. 106 min (p=0.021); reintroduction of diet: 3.3 days vs 2.1 days (p=0.009); discharge: 5.8 days vs 4.3 days (p= 0.044). In gastrostomy, relevant data were operative time of 122.6 min vs 86.2 min (p= 0.012 and hospital discharge: 5.1 days vs 3.7 days (p=0.016). CONCLUSION: The comparative analysis of laparotomy and video-assisted access to jejunostomies and gastrostomies concluded that video-assisted approach is feasible method, safe, fast, simple and easy, requires shorter operative time compared to laparotomy, enables diet start soon in compared to laparotomy, and also enables lower length of stay compared to laparotomy.

Technical Simplification

The purpose of this paper is to show that by a reorganization of the proofs of the main results concerning Radon-Nikodym derivatives in a von Neumann algebra of Pedersen and Takesaki in [12] and of Connes in paragraphs 1.1 and 1.2 of [5], considerable technical simplification can be achieved. Roughly speaking, the analytic vector techniques developed by these authors for the study of weights on a von Neumann algebra can be replaced, to a large extent, by the tensor product methods introduced by Connes, which are essentially algebraic in nature. In the exposition which follows, analytic vectors are not used at all (see, however, 4.4).
