the authors report on a rare case of acute myocardial infarction associated with dissection of the aortic arch. Treatment and differential diagnosis are presented. Early administration of fibrinolytic agents is undoubtedly…

Fractures about the calcaneus and intraarticular calcaneal fractures with displacement of fragments should be treated operatively. Complete reconstruction of the calcaneus is a demanding procedure because of a complex structure…

Transmetatarsal osteotomies (TMO) are indicated primarily in adduction deformity of the anterior part of the foot or the great toe. Most commonly this deformity occurs as a result of unsuccessful…

An image is a two-dimensional representation of a three-dimensional object. Images obtained by physical or optic sectioning can be used for stereological analysis, while those resulting from projection from the…

Mechanically induced peripheral nerve lesions are among the commonest neurological disorders. Pressure neuropathies (due to acute compression) differ form entrapment neuropathies (due to chronic constriction, repeated pressure or angulation) in…

The basic features of a simple static three-dimensional mathematical model of an adult hip in a monopodal body position are given. The described model can be used in clinical practice…

The article deals with the development of blood cells, as well as with the appearance and disappearance of particular cell markers in different periods of lymphatic and myeloid cell maturation.…

Pathophysiological mechanisms of flaccid and spastic paralysis are presented. Characteristic features of flaccid paralysis described in the paper include decreased muscle strength, hypotonia or atonia, depressed or absent proprioceptive reflexes,…

Transcranial magnetic motor cortex stimulation (MS) was standardized by measuring the central motor latency (CML) of the abductor digiti minimi (AM) and tibialis anterior (TA) in 18 healthy subjects. Normal…

Liposomes are lipid vesicles used in research and therapy. In the present study, liposomes were fractionated by gel chromatography and their characteristics were determined by electron paramagnetic resonance (EPR). From…
