World Health Organization includes the eight main risk factors, which causes about 61% of cardiovascular deaths. These factors are: tobacco and alcohol use, high blood pressure, high body mass index, abnormal blood lipid levels, high blood glucose, a diet high in saturated fat and low in fruit and vegetable intake and physical inactivity. Thanks to them it's possible to expect probability of illness and its complication. Particularly exposed to cardiovascular morbidity are those patients who have multiple risk factors. The investigated group consisted of 114 male patients, who lived in Poznan. The authors analyzed lifestyle factors (smoking, prophylactic examination, exercise and leisure activities and diet), which were compared with laboratory and diagnostic tests plus selected individual characteristics of respondents. Answers distribution within the group are presented as percentages. The aim of the study was to analyze health behaviors among men age > 50 years related to risk factors cardiovascular diseases. Results shows that most of the study group had overweight or obesity and their daily physical activity was confined only to the work in the garden or walking. There were 33% of men with BMI>30, which increases their risk of heart attack twice. Incidence of hypertension was related to obesity, high blood cholesterol and high triglyceride levels. Vascular interventions occurs more frequently among daily smokers and former smokers. More than half of study group with hypertension stopped smoking because of their diseases. Men who declared healthy lifestyle more frequently perform prophylactic control tests and examination. Mostly three or four risk factors were found among study group. For the men after 50 there should be implemented more prophylactic programs, to encourage lifestyle changes and eliminate risk factors. Source

Autoimmune thyroiditis (Hashimoto's disease) is a polygenic disorder with complex etiopathogenesis. Apoptosis is proposed as one of its mechanisms. Programmed cell death is essential for the maintenance of homeostasis, but when it is deregulated, it may contribute to the development of disorders. There are two apoptotic pathways: intrinsic and extrinsic. The extrinsic pathway may be activated among others through FasL binding to its receptor Fas. The FasL induced apoptotic pathway proceeds with cascade activation of following caspases, with final effector proteins recruitment. There is also a group of inhibitory proteins of apoptosis, where the Bcl-2 protein predominates. In the course of Hashimoto's disease the following aberrations are encountered: increased Fas/FasL expression, caspases and Bid protein concentrations, decreased Bcl-2 concentration and at the same time increase of Bcl-2 within intrathyroidal lymphocytes. They favor the thyrocytes apoptosis and thyroid gland destruction. Synergistically acting proapoptotic cytokines IFN-y and TNF or IL-β, are considered to be major factors of the abnormalities mentioned above. TSH, T 3 and T 4, TSAb and TSBAb antibodies and iodide concentration may also play a role in pro-and antiapoptotic factors expression regulation. The role of TRAIL protein in the course of Hashimoto's thyroiditis needs evaluation. The current data on the role of apoptosis in the etiopathogenesis of the autoimmune thyroiditis will be presented and discussed. Source

Photodynamic therapy (PDT) is used mainly in tumor diagnosis and treatment. It is obvious that PDT can increase the efficiency of traditional methods such as surgery, chemotherapy or radiotherapy. Unfortunately, photosensitizers used in the treatment are still imperfect. According to severe side effects, patients need to change their life habits even for several weeks. The problem is attributed to insufficient selectivity of dyes toward cancer tissues. Safety of PDT can be improved by application of various carriers including liposomes, nanotubes or nanoparticles. Binding of photosensitizers to tumor specific molecules opens broad new possibilities for PDT. Source

The cellular vaults have been described for the first time in 1986 as ribonucleoprotein complexes composed of three proteins, MVP, TEP1 and vPARP and several vRNA strains. Biochemical and structural studies revealed their ubiquitous existence in the cytoplasm of many eukaryotic cells and their barrel-like structure indicating their engagement in the intracellular transport. Furthermore, the high homology between MVP and LRP which was already known to be involved in multidrug resistance mechanism opened a discussion about the role of vaults in both normal and cancer cells. The histopathology research demonstrated an increased amount of MVP/LRP proteins in the cancer as well as showed translocation possibility between cytoplasm and nuclear envelope, which can be of crucial point in the prevention of nucleus against anticancer drugs.

Antibiotics have significant role in the treatment of respiratory diseases. The main aim of their use is to treat infection, but anti-inflammatory properties of macrolides are also beneficial in selected diseases. The role of antibiotics in the therapy of asthma exacerbation can be neglected and should be limited to exceptional situations of bacterial infections which are very rare. During last few years the role of atypical infections in asthma inception, induction of exacerbation and modification of chronic course of disease has been discussed. Antibiotics play significant role in cystic fibrosis therapy. They are especially recommended during exacerbation, when new pathogens are revealed and in chronic Pseudomonas aeruginosa infection. This paper includes the principal rules of antibiotics therapy in patients with cystic fibrosis. The role of azithromycin in antiinflammatory therapy in this group of patients is also presented.
