Acute tricuspid valve regurgitation in a motorcycle accident

Tricuspid regurgitation is secondary in 90% of cases. We would like to present two case reports of primary tricuspid regurgitation caused by rupture of the papillary muscle as a result of traffic accidents. This series of cases presents a very rare heart injury caused by blunt chest trauma. Regular monitoring of echocardiographic parameters in the period between the stabilization of patients' condition after the accident and surgical correction of the tricuspid valve defect is an important point of patient care with severe tricuspid regurgitation.Tricuspid regurgitation is secondary in 90% of cases.

Ocena ryzyka wystąpienia incydentów sercowo-naczyniowych według SCORE w grupie osób aktywnych zawodowo

Incydenty sercowo-naczyniowe, takie jak zawał serca czy udar mózgu, to najczęstsza przyczyna zgonów osób przed 65. rż. w krajach Europy. Polsce daleko jeszcze do najniższych wartości współczynnika umieralności w tym mechanizmie, obserwowanych na zachodzie kontynentu. Poniżej przedstawiono analizę wyników studenckiej akcji edukacyjno-profilaktycznej badającej czynniki ryzyka incydentów sercowo-naczyniowych i ich zależności w grupie ponad 100 Polaków aktywnych zawodowo.

A case report of a 72-year-old man with left ventricular free wall rupture following acute myocardial infarction

Mechanical complications after acute myocardial infarction (AMI) are rare, but they have dramatic consequences and high mortality. Our work presents a case report of a 72-year-old man with left ventricular free wall rupture as a result of acute myocardial infarction.Mechanical complications after acute myocardial infarction (AMI) are rare, but they have dramatic consequences and high mortality.

Domain structures and magnetization processes in thin Co films with in-plane anisotropy

The magnetization reversal and domain structures in thin Co films in the thickness range 2 nm<d<100 nm whith in-plane magnetic anisotropy were studied. Both magneto-optical (MO) vector magnetometry and MO microscopy were used. The crossover of in-plane anisotropy symmetry from two-fold to six-fold were observed with increase of Co layer thickness from 2 nm to 100 nm. The evolution of the domain structure during the magnetization reversal process was studied for different orientations of magnetic field relatively to anisotropy easy axis using longitudinal Kerr MO microscope

Magnetic anisotropy changes in ultrathin Co films grown on vicinal sapphire substrates

The aim of the work is to study the magnetic anisotropy changes in epitaxial ultrathin Co films grown on vicinal sapphire substrates with different miscut angles. Changes of the in-plane magnetic anisotropy symmetry were deduced from magnetooptical hysteresis loops shape and angular dependence analysis of the resonance field measured in the sample plane. Two-fold and four-fold symmetry of the in-plane anisotropy was observed for different miscut angles. The experimental data are discussed taking into account the following energy contributions: (i) demagnetization; (ii) perpendicular uniaxial anisotropy (iii) and step-induced uniaxial anisotropy. Magnetic anisotropy constants are fitted to the experimental results for different miscut angles

Transverse magneto-optical Kerr effect measured using phase modulation

An ellipsometric configuration for measurement of the complex transverse magneto-optical Kerr effect is described that uses a photoelastic modulator (PEM). The real and imaginary parts of the complex transverse Kerr effect are represented as small perturbations of ellipsometric angles psi and Delta. The measurement, based on null ellipsometry and zone averaging, gives high signal typical for modulation techniques and insensitivity to other magnetisation components and system imperfections. The method is demonstrated by the measurement of transverse component during magnetisation reversal in a thin cobalt film.Web of Science1art. no. 0601
