Neoplastic diseases are the second cause of death. Each year about 90 thousand people die because of cancer. It is estimated that this number will keep growing, becoming in the near future, the first cause of death before 65 years of age for both women and men. Tumors are a serious health and social problem of the 21st century.
According to WHO, HCV infection should be diagnosed in 2 steps. The first step is screening and serological test for anti-HCV antibodies. If the result is positive, it is necessary to carry out nucleic acid test for HCV RNA (NAT). It is needed to confirm chronic HCV infection. RNA of virus appears in the plasma 1-2 weeks after infection. RNA level gradually increases, but after some time this level falls and RNA test of HCV could be temporarily negative. HCV antibodies appear in 8-10 weeks after infection.
Recent studies presented at the conference of the European Society of Human Genetics in Barcelona, Spain, shows that men whose red blood cells are characterized by the absence of the Y chromosome, are more prone to reveal Alzheimer’s disease. Scientists hope that in the future these results can be the basis for the early identification of people with increased risk of this disease.
The latest research conducted by researchers at the University of Utah shows that proper parenting strategies can mitigate the devastating impact of maternal depression on infant development. The data, published in the Child Development, reported that appropriately sensitive care from the mother greatly reduces the level of stress in the infant by influencing the neuroendocrine system.

Su-Chun Zhang from the University of Wisconsin-Madison, a pioneer in the processing of stem cells into neurons, together with other scientists developed specialized nerve cells that produce serotonin (a neurotransmitter in the brain). The study was published in the Nature Biotechnology. Read full text »
Prostate cancer is the most common carcinoma of urogenital organs. It is the second most common cancer occurring among the whole male population. Annually there are 9000 new cases diagnosed and a rising tendency has been observed throughout the last 3 decades. Despite of a wide access to radio- and chemotherapy as well as various hormonal therapies and surgical methods, this neoplasm causes around 8% of all deaths in Poland every year. Scientists from Houston Methodist Hospital in Texas have come up with a new method of prostate cancer treatment which is both effective and safe for the patients. It is based on the modification of cancer cell genes with the use of a virus which causes the immune system of a patient to recognise and attack the infected tumour cells.
Cataract is the main cause of both the deterioration of and the loss of eyesight in the world. This, in turn, causes not only a serious disability, but also a lowering of the quality of the patients’ life together with burdening the budget of the developed countries since the disease concerns mainly the aging populations. Until now the only cataract treatment perspective was the use of various surgical methods. This situation can be changed, however, by the discovery of the team of scientists from the University of California in San Diego who have described lanosterol as the potential eye drop ingredient that could contribute to the development of pharmacotherapy of the disorder.

Food allergies are very common in children (6-8%) and sometimes they can even be life-threatening. Also, the quality of life of young patients and their families is severely affected. Currently, therapy of allergy is limited to avoidance of allergens and “rescue” pharmacological treatment. More and more doctors believe that the future is in active approach to the problem. Anticipatory testing, early introduction of potential food allergens, and active tolerance induction are the basis of the new model of treatment. Read full text »
Scientists from the University of Colorado Cancer Center revealed positive correlation between mutation of the gene ETV6 and an incidence of acute lymphoblastic leukemia (ALL). This finding will help to identify the population of patients at higher risk of developing the disease who require screening. Read full text »
The multi-center clinical study, conducted by researchers from Yale Cancer Center revealed the expression of immune-suppressing protein PD-L1 on tumour-infiltrating immune cells may predict how patients with various types solid tumors respond to immunotherapy. Read full text »
