Low level laser therapy (LLLT) has been used successfully in biomedicine and some of the results are thought to be related to cell proliferation. The effects of LLLT on cell proliferation is debatable because studies have found both an increase and a decrease in proliferation of cell cultures. Cell culture is an excellent method to assess both effects and dose of treatment. The aim of this stud...

The unresolved debate about frozen embryos has left open the discussion on "what to do with them". There are only three ways to deal with frozen embryos: 1) to leave them frozen indefinitely; 2) to defrost and discard them and 3) to use them for research. In this paper, we suggest that the application of current scientific knowledge, instead of inappropriately referring to ethical principles or...

PURPOSE To access the reliability of fine-needle aspiration biopsy in harvesting a sufficient amount of viable melanoma cells to establish a cell culture and maintain a melanoma cell line from an animal model of uveal melanoma. METHODS For this study, fifteen male New Zealand albino rabbits had their right eye surgically inoculated with uveal melanoma cell line 92.1. The animals were immunosu...

The aim of this study was to assess the effect of 635- and 670-nm laser irradiation on H.Ep.2 cells in vitro using MTT. In addition to our previous report on the effects of LLLT on the proliferation of laryngeal carcinoma cells in which it was found that irradiaton H.Ep.2 cells with 670-nm laser results in increased cell proliferation, it was decided to evaluate the effect of increased doses of...

We have developed a new approach (MDLEP) to learning Bayesian network structures based on the Minimum Description Length (MDL) principle and Evolutionary Programming (EP). It integrates a MDL metric founded on information theory and several new genetic operators including structure-guided operators, a knowledge-guided operator, a freeze operator, and a defrost operator for the discovery process...

Many scientists now manage the bulk of their bibliographic information electronically, thereby organizing their publications and citation material from digital libraries. However, a library has been described as "thought in cold storage," and unfortunately many digital libraries can be cold, impersonal, isolated, and inaccessible places. In this Review, we discuss the current chilly state of di...

In this paper, dynamic simulations of the seasonal coefficient performance (SCOP) Air-Source Heat Pumps will be presented by considering three different heat pump systems coupled with same building located in Italian municipalities: S. Benedetto del Tronto (42°58′ North, 13°53′ East), Milan (45°28′ 9°10′ and Livigno (46°28′ 10°8′ East). Dynamic were conducted employing software package TRNSYS r...

In wood processing, is exposed to an environmental temperature of less than 0 °C for some time, which mainly occurs during the air drying in winter months, or when lumber stored piles outdoors before kiln process. these cases, freezing process increases degree wood, subsequently significantly affecting its heating further processing (for example, cutting process). The most common method by humi...

Title of Document: INVESTIGATION OF REFRIGERANT DISTRIBUTION IN A HOUSEHOLD REFRIGERATOR WITH A FOCUS ON THE ROLE OF THE ACCUMULATOR Cara Sanderson Martin, M.S. Mechanical Engineering, 2007 Directed By: Professor Reinhard Radermacher, Ph.D. Department of Mechanical Engineering In order to maximize household refrigerator performance, it is important to understand the basic relationship between e...
