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.
Alzheimer’s disease is the most common condition of the central nervous system responsible for the symptoms of dementia. This defect is clearly associated with age and more often manifests itself in women. The reason of the disease is not fully understood. It is known that the pathogenesis involves accumulation of insoluble protein Aβ in the brain. Recent years brought growing interest in Alzheimer’s disease and scientists have put forward assumptions that the HSV1 virus infection may be associated with this condition. Researchers from Umea University in Sweden have conducted a prospective study in order to prove this relationship.
The first case of viral hemorrhagic fever, which is caused by Ebola virus, was recognized in 1976 in Sudan. From then on epidemics of the illness have led to death of over 1000 people in Africa. It has resulted in scientists who started to search effective vaccine. Results of a research conducted over the recent years show that prevention of the terminal illness will be possible.

Korean Scientists, Lee et al., in their epidemiological molecular investigation identified specific W4P/R preS1 mutation of hepatitis B virus (HBV) in male patients with genotype C of chronic infection. They indicate that it may contribute to hepatitis progression and the development of hepatocellular carcinoma (HCC). Read full text »
Recently the world has held breath as the new dangerous disease was discovered. The Adult-Onset Immunodeficiency Syndrome (AOIS) resembles Acquired Immunodeficiency Syndrome (AIDS) not only in its name, but more importantly in its clinical course. Patients, who were born almost exclusively in Thailand or Taiwan present with symptoms of multiple opportunistic infections. Authors of the study (1) on AOIS, published in the August issue of prestigious New England Journal Of Medicine, claim there is no evidence on the viral etiology of the disease. However, as some media hailed AOIS as “HIV 2.0”, the tension remains. Read full text »
In the UK alone, 500 000 people are infected with Hepatitis C virus (HCV) and still, most of the patients are not diagnosed. Therefore, HCV infection is a major cause of liver transplantation there. A few years ago, scientists have found monoclonal antibodies which gave hope for the acquisition of an effective vaccine. Now, the first results of the testing of vaccines based on adenoviral vectors have occurred. Read full text »
