“The experimental study on the laser acoustic signal in salt water with different salinities using high power pulsed CO2 laser has been carried out. By using a hydrophone to receive the sound signal and further analyzing in time domain, the effects of the salinity and pulse energy on the characteristics of the sound signals were disclosed.
The results show that the salinity has significant effect on the characteristics of the laser acoustic signal. As the salinity increases, the amplitude of the sound signal decreases. The profile of the sound signal also changes with the salinity. As the salinity decreases, the changes in the signal waveform show the loss of its originally bimodal shape. This phenomenon is also found in the laser energy which decreases when the salinity is kept constant.”
“Purpose: find more A meta-analysis was conducted to obtain a ‘quantitative’ estimate of the extent of genetic damage in mammalian somatic cells exposed to non-ionizing radiation emitted from extremely low frequency electro-magnetic fields (ELF-EMF) and to compare with that in unexposed control cells. Methods: The methods used for the meta-analysis were recommended in several standard text books. Three specific variables related to ELF-EMF exposure
characteristics were examined in the meta-analysis: (i) frequency (Hz), (ii) flux density (mT), and (iii) in occupationally exposed individuals. Result and conclusions: (1) The difference between ELF-EMF-exposed and control cells as well as Selleckchem Momelotinib the ‘effect size’ due to ELF-EMF exposure were
biologically small (although statistically significant) with very few exceptions. (2) At certain ELF-EMF exposure conditions there was a statistically significant increase in genetic damage assessed from some end-points. (3) The mean indices for chromosomal aberrations and micronuclei end-points in ELF-EMF-exposed and control cells were within the spontaneous levels reported in historical database. (4) Considerable evidence for publication bias was found in the meta-analysis.”
“Malignant fibrous histiocytoma (MFH) of PDGFR inhibitor the kidney is a rare sarcoma that often undergoes local recurrence and/or distant metastasis. However, little is known about the outcome of metastatic diseases. We present the case of a 46-year-old male suffering from renal MFH with pulmonary metastasis, who has undergone complete response for 3 years after surgical resection and MAID chemotherapy. He is now well, and without any evidence of recurrent disease. Copyright (C) 2010 S. Karger AG, Basel”
“Objectives: Switching from peritoneal dialysis (PD) to hemodialysis (HD) is undesirable, because of complications from temporary vascular access, disruption of daily routine, and higher costs. Little is known about the role that social factors play in technique failure.
Design, Setting, Participants, Measurements: We followed for 3 years a nationally representative cohort of US patients who initiated PD in 1996 – 1997.
