    Introduction: Most cases of peritonitis during continuous ambulatory peritoneal dialysis (CAPD) are attributed to breaches of the aseptic technique. In this report, we describe an outbreak of CAPD related peritonitis that followed the use of potentially contaminated PD fluid. Outbreak report: CAPD was introduced in the adult nephrology unit at Soba University Hospital in December 2008 with fairly satisfactory functioning and results. In June 2009, we obtained a new supply of PD fluids and started using it. Soon afterwards, a mould was found inside a new unused dialysate bag. During the following days, six patients were diagnosed to have PD related peritonitis. All patients in the unit were immediately shifted to another brand of PD fluids. Enquiry revealed that this supply of PD fluid was stored in a warm and humid environment. We surveyed the 1469 bags in the hospital stock and found another three bags (0.2%) that contained visible mould by the naked eye. The four contaminated bags contained 2.5% dextrose and were from different batches. All of them had lost the negative vacuum between the inner bag and the outer plastic envelope, but had no obvious tears in the envelope and no obvious fluid leakage. Our peritonitis rate before the outbreak was one episode in 21.7 patient-months. This sharply rose to one episode in 2.5 patient-months during the month of the outbreak, and dropped down to one episode in 17.8 patient-months in the 6-months following the outbreak. Conclusion: Contamination of PD fluids can occur during handling and storage. Patients should meticulously examine each bag before usage. Any bag that has lost the vacuum between the inner bag and its outer envelope is potentially breached and should not be used.

    Parallel Implementation of Systolic Array Design for Developing Medical Image Rotation

    Get PDF
    Many image-processing algorithms are particularly suited to parallel computing, as they process images that are difficult and time consuming to analyse. In particular, medical images of tissues tend to be very complex with great irregularity and variability in shapes. Furthermore, existing algorithms contain explicit parallelism, which can be efficiently exploited by processing arrays. A good example of an image processing operation is the geometric rotation of a rectangular bitmap. This paper presents a set of systolic array designs for implementing the geometric rotation algorithms of images on VLSI processing arrays. The examined algorithm performs a trigonometric transformation on each pixel in an image.  The design is implemented as a distributed computing system of networked computers using Parallel Virtual Machine (PVM) model. Each node (computer) in the network takes part in the task in hand – such as image processing – using message passing. Comments and conclusions about the implementation of the design as a distributed computing system are discussed. Keywords: parallel computing, distributed computing. PVM, image rotation, systolic array

    Large areas in many countries are populated but have no connection to a national electricity grid. Centralized electricity generating facilities burning fossil fuels have been the normal. Renewable energy resources, especially solar energy is now penetrating this sector. Long-term energy storage is the universal challenge in providing renewables-based electricity with high availability across the seasons. Solar domestic hot water system is widely used and developing fast in recent years. However many problems occur at the same time, for example more energy consumption by circulation pump, water reheating, long investment payback period, and etc. The motivation for the development of a combined hot water and sorption store is to complement the advantages and to reduce the disadvantages of the two particular storage technologies. Hot water stores offer high heat supply rates but are particularly suitable for short term storage due to heat losses whereas for a sorption store the power drain is low but it shows the advantage of a high storage density and long-term heat storage almost without losses. We investigated the demonstration project and discuss the need for authoritative system modelling in order to size the system components for minimum cost at a designated availability of supply

    Stem cells differentiation and probing their therapeutic applications in hematological disorders: a critical review

    Get PDF
    Numerous lines of evidence support that bone marrow is a rich source of stem cells that can be used for research purposes and to treat some complex blood diseases and cancers. Stem cells are a potential source for regenerative medicine and tissue replacement after injury or disease, and mother cells that possess the capacity to become any type of cell in the body. They are cells without specific structure and characterized by their ability to self-renew or multiply while maintaining the potential to develop into other types of cells. Stem cells can normally become cells of the blood, heart, bones, skin, muscles or brain. Although, there are different sources of stem cells, all types of stem cells have the same capacity to develop into multiple types of cells. Stem cells are generally described as unspecialized cells with unlimited proliferation capacity that can divide (through mitosis) to produce more stem cells. Several types of adult stem cells have been characterized and can be cultured in vitro, including neural stem cells, hematopoietic stem cells, mesenchymal stem cells, cardiac stem cells and epithelial stem cells. They are valuable as research tools and might, in the future, be used to treat a wide range of diseases such as hematological hereditary diseases, Parkinson's disease, diabetes mellitus, heart disease and many other diseases. Currently, two types of stem cells have been identified based on their origins, namely embryonic stem cells and adult stem cells. Collectively, although many kinds of literature have been studying stem cell application in terms of clinical practice, stem cell-based therapy is still in its infancy stage
