Rotablation - In cardiac surgery, the stoma is pierced through the narrowed artery. Rotablation is performed in patients with vasodilatation of more than 90% and angioplasty is not possible because their vessels due to large calcifications are too hard to carry through the balloon, and ballooning may result in arterial rupture. .

In the procedure after insertion of the guide into the tapered vessel, a rotating diamond drill having a diameter of about 1 mmm with an angular speed of 140,000 rpm is introduced. A stent coated with an antiproliferative drug, which minimizes the risk of restenosis, is introduced into the reed artery. Drills in Poland are used in less than 1% of patients and in Western Europe in 4% to 7%.

Myrmex Indikos, pol. Indian ant - an alleged species of gigantic ants (according to Herodot's description, larger than foxes, but smaller than dogs). The earliest mention of these creatures is dated to the fifth century BC, and its author is Herodotus. According to her, these ants inhabited the deserts of Persia and India and extracted gold from their sands. Several such creatures were kept in the residence of the King of Persia. Gold was to be obtained by caravans made up of several camels in the heat of the day, when the ants were protected underground. You had to do it quickly, because the ants sensed the smell of people and went on the pursuit, and they were deadly dangerous. This story is confirmed by the next accounts: Nearchos, one of the army officers of Alexander Macedoński, and Megastenes - a historian and traveler. The fragment of the Megasthenes (IV-III century BC) preserved in fragments can be seen in the underground mines at the foot of the mountains on the easte...

The names of the streets and squares were originally of a topographical nature, that is, they informed about: Researchers propose two names for these toponyms - urban or plateonimy. S. Urbańczyk points out that the older names were spontaneously formed and sprouted in the daily lives of the inhabitants of the place. The information contained herein was related to the characteristics of the place (eg appearance), important road directions (geographic orientation) or values, functions and economic meanings called places / objects in the settlement for the inhabitants' lives.
