The purpose of the study was to discover a way to study the internal structure and evolution of human embryos noninvasively. The human embryo was stained with phosphotungstic acid solution (PTA) in ethanol (EPTA) and scanned using a micro computed tomography (micro-CT) scanner. Using appropriate software, a three-dimensional image of the embryo was created, which could be further exploited. The methodology described could be used for the non-destructive examination of the internal structure of the human embryo, and the resulting data can be used as a resource for medical students, gynaecologists, and paediatricians.

From the end of the fifteenth century, the massive expansion of syphilis had a distinct effect on the historical development of Europe. Due to this disease, firstly the numbers of the European population were reduced; thereafter, moral and ethical principles were significantly affected and the combat readiness of armies decreased. The disease forced new legislation which was of vital importance for the development of health services. The Czech Lands, located in Central Europe, were also no exception. The material presented summarises the available information on this disease obtained from written sources and from the study of direct evidence of skeletal remains from archaeological sites of Bohemia, Moravia and Silesia. Traces of syphilitic bone affliction have observed in almost every large early modern osteological collection to date. A number of currently documented palaeopathological findings of syphilitic changes in bones from the Czech Lands do not by a long stretch correspond to the data presented in literary sources on the mass occurrence of this disease. The submitted study aims to extend current knowledge in this area and thereby to complete a complex view of the development of syphilis in Central Europe.

In this paper, we describe a very rare variant in the course of the ulnar artery that we encountered in dissecting the right upper limb of a 74-year-old man. The ulnar artery arose standardly from the brachial artery in the cubital fossa. However, its ensuing course differed from the norm. The artery entered together with the ulnar vein and median nerve into the pronator canal (between the humeral and ulnar heads of the pronator teres). Further, the ulnar artery descended classically to the ulnar side of the forearm between the flexor carpi ulnaris and flexor digitorum superficialis. Knowledge of this variation in the course of the ulnar artery may have significance in clinical practice because accumulation of anatomical structures in the pronator canal could be a predisposing factor for the compression of nerve or blood vessels. Keywords: anatomical variation; median nerve; pronator canal; pronator teres muscle; ulnar artery.
