Background The use of ultrasonic devices has been shown to be very successful for the removal of various canal obstructions.3-5 The use of ultrasonics is advantageous over conventional methods for removal of separated instruments as it is able to set separated instruments free from canals while making the sacrifice of dentin significantly less.6 However, there are several negative factors when ...

It is time hospice and palliative care grew up. We can no longer expect governments to treat them as a charity case, with just enough funding to avert adverse newspaper headlines. Increased financial pressure from the global economic recession and fiscal crisis on already stretched budgets means tough decisions have to be made about where to invest limited health funds. Consequently, we need to...

We demonstrate an algorithm that can separate any number of points in n-dimensional space from one another by planes. Given a set G of Nf points, along with their coordinates, in n-dimensional X-Space, the algorithm partitions all the Nf points by using planes such that no two points are left un-separated by some plane. The algorithm proceeds by transferring points from G to another set S in n-...

the main goal of this report was to share with clinicians an atypical presentation of pulmonary thromboembolism (pte) in a young male`s post-appendectomy, whom he had no significant predisposing factors for such disease. the case also introduced for re-examining the challenges of pte clinical manifestations which may mimic other differential diagnosis. pte is an abrupt blockage of the pulmonary...

purification of parasitic antigens is a major activity in immunoparasitology because of its application in immunodiagnosis, vaccination analysis of immunopathology, preparation of monocolomal antibody and finding out the cross reactive antigens versus specific antigens of a parasite. in this survey f2 ultrafiltration excretory secretory antigens of ascaris lumbricoides and toxocara cati were se...

Membrane vesicles from the envelope of Escherichia coli were separated by electrophoresis through dilute agarose and by sizing chromatography through Sephacryl S-1000. These techniques revealed that proteins were associated with different subsets of vesicles. In particular, dilute agarose electrophoresis clearly separated the inner membrane penicillin-binding proteins (PBPs) into different vesi...
