An alternative approach for the electron microscopical examination of undecalcified human bone was investigated. The method required bone to be chilled to -70 degrees C, sectioned at 10 microns in a special bone cryostat, and these sections to be fixed and embedded for ultrathin sectioning. Good preservation of bone cells was seen. The advantages of this method are that it allows numerous parti...

BACKGROUND The most widely used preservation method for kidney grafts is cold static storage (CS) using the University of Wisconsin (UW) solution. To date, new preservation solutions have not been able to significantly improve preservation quality of grafts. The aim of this study was to compare POLYSOL, a recently developed low viscosity preservation solution, and the UW solution for CS of porc...

Natural food preservation method refers to application of naturally produced antimicrobial compounds that are obtained from plants, animals and microbes to prevent food spoilages microorganism, proliferation and growth of food borne pathogens in food and foods products. Now it is the time of growing interest of many researchers with the application of these natural antimicrobial compounds as sa...

As the efficacies of anticancer therapies were increase and quite efficient early diagnoses have been taken place in gynecological cancer, increased long-term survival of cancer patients and long-term complications of anticancer treatments are being encountered. The lost of ovarian reserve or function due to gonadal toxicity is the major problem that mainly focused. A wide range of new fertilit...

Pancreas preservation by cold storage using University of Wisconsin solution was the mainstay method used for pancreas transplantation during the past 2 decades. Other solutions, such as HTK, Celsior, and SCOT 15, could not demonstrate any advantage for short preservation periods. But the advent of clinical islet transplantation and the larger use of controlled non–heart-beating donors have pro...

Solid organ transplant constitutes the definitive treatment for end-stage organ failure. Better organ preservation methods have enabled use of marginal grafts, thereby expanding the donor pool to meet the growing demand for organs. Static cold storage as a preservation method has been superseded largely by machine perfusion in kidney transplant, with work regarding its use in other organ transp...

The algorithm of Minh as in [Minh (1988)] was used to generate variates having a gamma distribution with shape parameter a>1 only. In this paper, a method, which is the improvement of the algorithm of Minh is introduced for the generation of independent random variables from a gamma distribution with all values of shape parameter and is compared with the method of Marsaglia and Tsang. By means ...

The advantages of freeze-drying are obvious. It is a convenient method for the preservation and long-term storage of a wide variety of microorganisms. However, special precautions are needed for the preservation of microorganisms sensitive to desication, light, oxygen, osmotic pressure, surface tension and other factors. During several years of experimentation I have developed various new metho...

Hurdle technology is a method of ensuring that food products will be safe for consumption and extending their shelf life. It also ensures that pathogens in food products will be eliminated. Hurdle technology is used in food industry for the gentle but effective preservation of foods. The shelf life, sensory and nutritional quality of foods are based on applications of combined preservative fact...

This discussion outlines some of the issues that must be considered before digital imaging of paper-based research material should be adopted as a preservation method. In addition, the quality of the digital image in terms of resolution and pixel depth, as well as issues of authenticity, verification, and bibliographic integrity will be discussed. In this context, issues associated with preserv...
