Introduction: Dysferlin-deficient murine muscle sustains severe damage after repeated eccentric contractions.
Methods: With a robotic dynamometer, we studied the response of dysferlin-sufficient and dysferlin-deficient mice to 12 weeks of concentrically or eccentrically biased contractions. We also studied whether concentric contractions before or after eccentric contractions reduced muscle damage in dysferlin-deficient mice.
Background: Isolated fibrous tumor of the pleura (SFTP - Solitary fibrous tumour of the pleura/localized fibrous tumour of the pleura) is a rare primary tumour of the pleura of mesenchymal origin. In most cases, it is a benign lesion. It is composed of spindle cells similar to fibroblasts and derives probably from submesothelial mesenchyme.

MRCP technique utilizes T2-weighted sequences, in which bile is characterized by high signal intensity, whilst signal intensity of surrounding tissues is reduced. The purpose of this publication was to assess the diagnostic value of magnetic resonance cholangiopancreatography in the diagnostics of biliary dilatation.

In addition, they both depend on uniform distribution of emitted pulses throughout the treated skin area. The pulses should be closely adjacent but they should not overlap.

There is need to develop drugs that inhibit excessive infiltration of monocytes and lymphocytes to the arterial wall and central nervous system. The aim of this study was to evaluate the effect of apigenin on the synthesis and release of MCP-1 by J774.

A significant difference between the copy numbers of mRNA for 5-alpha-reductase type 1 and type 2 was disclosed. The content of the mRNA copies was higher for 5-alpha-reductase type 2 than for type 1.

Apigenin, kaempferol and resveratrol present in fruits, vegetables and grain were investigated for their effect on the synthesis of interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha) at transcriptional level in lipopolysaccharide (LPS)-stimulated J774.2 macrophages.

Apoptosis inhibition, in turn, depends partly on the balance between expression of two cell death regulatory genes, Bcl-2 and Bax. Colon cancer has long been associated with disturbances in apoptosis regulation.

View Article and Find Full Text PDFTelomerase is a reverse transcriptase that adds repetitive telomere sequences to the end of chromosomes, which is thought to be essential for cellular immortality and oncogenesis. The enzyme consists of three subunits: human telomerase reverse transcriptase (hTERT), human telomerase RNA (hTR), and telomerase protein 1 (TP1). The hTERT subunit determines the activity of telomerase as an enzyme and is detected in most human tumors and regenerative cells.

View Article and Find Full Text PDFFunctional genetic polymorphisms of DNA repair genes are good candidates for cancer susceptibility markers. We studied two genes coding for proteins removing small DNA adducts by direct repair (MGMT), or mispaired DNA bases by base excision repair (TDG). The non-silent polymorphisms of MGMT (84:Phe, 143:Val, 178:Arg) and TDG (199:Ser, 367:Met), and the functional MGMT enhancer polymorphism, did not show any statistically significant association with lung cancer risk in our case-control analysis, but due to the relatively small number of individuals, strong conclusions on cancer risk association or lack thereof cannot be made.

Based on radiological examinations of bone system done for 1518 emergent, post-traumatic cases registered in an admission room, the authors have tried to perform a reliable analysis of the usefulness of the examinations. First of all, they have indicated that there were big differences between the requested x-ray examinations and their results. It has been noticed that the particular overstatement was employed during skull examinations especially for children, for which the detectability of changes in relation to the number of patients was equal to 7%.

Based on 262 radiographic examinations done during two years the authors have analyzed the compatibility of the radiographic image with the clinical examinations and with the operation results. In the analysis the most frequently occurring lesion level having the character of hernia of the nucleus pulposus, age, sex, and the duration of the disease symptoms were taken into account. The effectiveness of the method, which was verified by surgery was 86.
