Complex Dynamics of Photoinduced Mass Transport and Surface Relief Gratings Formation.

The microscopic and semi-macroscopic mechanisms responsible for photoinduced mass transport in functionalized azo-polymers are far from deeply understood. To get some insight into those mechanisms on "microscopic" scale, we studied the directed photoinduced motion of single functionalized polymer chains under various types of polarized light illumination using Monte Carlo bond fluctuation model and our kinetic Monte Carlo model for photoinduced mass transport. We found sub-diffusive, diffusive and super-diffusive regimes of the dynamics of single chains at constant illumination and mostly super-diffusive regime for directed motion in the presence of the gradient of light intensity.

Polyunsaturated Fatty Acids and Their Potential Therapeutic Role in Cardiovascular System Disorders-A Review.

Cardiovascular diseases are described as the leading cause of morbidity and mortality in modern societies. Therefore, the importance of cardiovascular diseases prevention is widely reflected in the increasing number of reports on the topic among the key scientific research efforts of the recent period. The importance of essential fatty acids (EFAs) has been recognized in the fields of cardiac science and cardiac medicine, with the significant effects of various fatty acids having been confirmed by experimental studies.

Omega-3 Fatty Acids and their Role in Central Nervous System - A Review.

Polyunsaturated fatty acids (PUFAs) are crucial for our health and wellbeing; therefore, they have been widely investigated for their roles in maintaining human health and in disease treatment. Most Western diets include significant amount of saturated and omega-6 fatty acids and insufficient quantity of omega-3; however, the balance between omega-6 and omega-3 PUFA, in particular, is essential for the formation of pro- and anti-inflammatory lipids to promote health and prevent disease. As our daily diet affects our health, this paper draws attention to unique representatives of the omega-3 fatty acid group: alpha-linolenic acid and its derivatives.

[Normal coronary angiogram in patient with diagnosis of acute coronary syndrome with ST segment elevation. Was it possible to recognise acute pulmonary embolism earlier?].

A case of a 48 year old male scheduled for early invasive treatment of acute coronary syndrome with ST segment elevation is presented. Clinical suspicion of acute pulmonary embolism was undertaken because of normal coronary angiogram and was confirmed by pulmonary angiography. Differential diagnosis based on medical history, electrocardiogram and laboratory findings was discussed.

[Acute myocardial infarction treated with primary PCI complicated by pulmonary embolism--a case report].

A case of 53-year-old male who was admitted to the hospital due to a chest pain, is presented. ECG showed ST elevation in precordial leads. The patient was successfully treated with primary angioplasty.

[Coronary angiography is not always helpful in differential diagnosis between perimyocarditis and myocardial infarction - four case reports].

Four males aged 17-42 years with ST-T segment changes suggesting perimyocarditis or non-Q acute myocardial infarction are presented. Coronary angiography was performed to establish the final diagnosis. Three patients had normal coronary arteries; two of them had typical clinical signs of perimyocarditis whereas the third patient had less typical changes.

[Repeated coronary angioplasty due to restenosis and disease progression - a case report].

We present a case of a 71-year-old male with exercise angina and two-vessel coronary artery disease (CAD). As the first step of treatment, the patient underwent successful coronary angioplasty with a stent implantation in the circumflex artery and remained free from angina for the following month. After this period, the patient underwent elective angioplasty of left anterior descending (LAD) coronary artery which was complicated by dissection, requiring implantation of two stents.
