MicroRNAs, which are endogenously expressed regulatory noncoding RNAs, have an altered expression in colorectal cancer. The aim of our study was to assess the relationship of miR-21 and miR-143 expression to the prognostic/clinicopathological features of colorectal carcinoma (CRC) and colorectal liver metastases (CLM). The estimation was performed in 46(More)
Recent studies indicate that fetal cells persist in maternal blood for decades after pregnancy. Maternal cells are known to engraft and persist in infants with immunodeficiency, but whether maternal cells persist long-term in immunocompetent offspring has not specifically been investigated. We developed sensitive human leukocyte antigen-specific(More)
BACKGROUND The matrix metalloproteinases (MMP) are a family of proteolytic enzymes involved in tumor growth and in the process of invasion. The aim of our study was to test the levels of MMP-2, MMP-7, and the MMP inhibitors TIMP-1 and TIMP-2 mRNA in colorectal carcinoma tissue samples with the clinicopathological status of the disease. PATIENTS AND(More)
BACKGROUND An essential step in the process of tumor invasion and metastasis involves the degradation of tissue barriers in the extracellular matrix (ECM), particularly in the basal membrane (BM). Matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinases (TIMPs), in particular MMP-2, MMP-7, TIMP-1 and TIMP-2, play an important role(More)
BACKGROUND Thymidine kinase (TK) plays an essential role in the processing of thymidine within the cell and therefore it is an important marker of proliferation, particularly in tumor cells. The aim of our study was to determine the diagnostic, prognostic and predictive importance of TK measurement in cancer. PATIENTS AND METHODS TK was measured using(More)
A 34-month-old girl with Down's syndrome from the Marshall Islands was hospitalized in September, 1981, at Tripler Army Medical Center for evaluation of a heart murmur and definitive repair of an imperforate anus for which she had had a colostomy since birth. She became jaundiced and had serologic evidence of hepatitis A infection. Over the next month eight(More)
The authors use a case report of a female patient with chronic abdominal pain progressing postprandially as an example to demonstrate the complexity of the diagnostic process in patients with these complaints, as well as a surprising peroperative finding in which a small neuroendocrine tumour of the small intestine was the cause of the difficulties. The(More)
Injuries to the pancreas are relatively rare, occurring in around 10% of case involving serious trauma to the abdominal cavity, with 65% of such injuries resulting trauma occurs only exceptionally, involving only 5% of all injuries. The mortality of this entity is influenced by many factors, especially the age of the injured person, the seriousness of the(More)
Bowel intussusception in adulthood is relatively rare. It is the cause of bowel movement disorders in around 1-5% of cases. In contrast to intussusception in childhood, where the cause is usually unclear, in adulthood the unequivocal causes are known in 70-90% of cases. These predominantly include benign tumours of the small intestine. The authors describe(More)
The authors operated in 1994-2000 at the Surgical Clinic, Faculty Hospital Plzen a total of 793 patients on account of thyroid disease. This group comprised 57 patients with malignant thyroid disease. The mean age of the operated patients was 48.8 years (range 12-89 years). Three patients (0.38%) died within 30 days after operation. The postoperative(More)
