Consequences of Insufficient Physical Activity: A Comparative Analysis of Poland and Europe.

Physical activity remains one of the most important factors affecting the well-being, health, and quality of life of individuals and entire populations. Unfortunately, the level of physical activity in many social groups is still insufficient according to the recommendations of the World Health Organization (WHO) and other international and national scientific societies. This paper presents the most important aspects related to the impact of physical activity on health, including lifestyle diseases, such as cardiovascular diseases, diabetes or obesity, mental health, and sleep, and overall mortality.

Anti-angiogenic agents in the treatment of non-small cell lung cancer.

Lung cancer is the most common malignant neoplasm diagnosed worldwide. In Poland, in 2011, lung cancer was diagnosed in 14,522 men and 6,283 women. Morbidity and mortality are nearly equal, and lung cancer is still the most common cause of cancer-related death among men as well as among women.

The application of real-time PCR technique to detect rare cell clones with primary T790M Substitution of EGFR gene in metastases of non-small cell lung cancer to central nervous system in chemotherapy naive patients.

The time-limited efficacy of reversible EGFR-TKIs in patients with advanced non-small cell lung cancer (NSCLC) with EGFR gene activating mutations is associated with development of treatment resistance after some period of therapy. This resistance predominantly results from secondary mutations located in EGFR gene, especially T790M substitution. There is limited information available concerning the prevalence of primary T790M mutations in patients with metastatic NSCLC tumors before treatment with EGFR-TKIs.

Sensitive methods for the detection of an insertion in exon 20 of the gene in the metastasis of non-small cell lung cancer to the central nervous system.

The HER2 (ErbB2/neu) protein is a member of the HER (ErbB) receptor family (EGFR, HER2, HER3 and HER4) that expresses tyrosine kinase activity in the intracellular domain. EGFR and HER2 overexpression is observed in numerous types of cancer, nevertheless, the susceptibility of patients with non-small cell lung cancer (NSCLC) to therapy with EGFR and HER2 tyrosine kinase inhibitors (TKIs) depends on mutations present in the respective coding genes (driver mutations). In the present study, PCR and amplified DNA fragment length analysis (FLA) were used along with the multi-temperature single-strand conformation polymorphism (MSSCP) technique in order to identify the 12 base pair insertion in exon 20 of the gene in 143 patients with NSCLC metastasis to the central nervous system.
