The formation of the tapetal periplasmodium inTradescantia bracteata is described at the electron microscope level and methods are given for the preparation of material. Evidence, both fine-structural and cytochemical, is presented in support of the view that the tapetal periplasmodium inTradescantia posesses an organized, functional ultrastructure. The(More)
A study of the ultrastructure of the microspores ofTradescantia bracteata has been made at all stages of development from the tetrad to the mature pollen grain. The principal observations concern the following structures. a) The exine which is developed mainly within the tetrad and possesses a regularly orientated fibrillar structure. b) The intine whose(More)
Tumor necrosis factor alpha (TNF-alpha) is known to induce wasting in humans and animals. This study was undertaken to determine TNF-alpha concentrations in children with sickle cell disease (SCD) and whether high TNF-alpha levels are more likely to be present in children with growth deficits, infection, or pain crisis. Tumor necrosis factor alpha was(More)
BACKGROUND Patients with an acute myocardial infarction require a rapid response to their symptoms and the earlier fibrinolysis is given (where indicated), the better the outcome. AIMS The aim of this study is to compare 'door to needle times' for fibrinolysis in Acute Myocardial Infarction (AMI) in three phases of one year each, at Letterkenny General(More)
Zinc deficiency has been implicated in impaired cell-mediated immunity of children with sickle cell disease (SCD). However, its influence on the expression of vascular cell-adhesion molecule-1 (VCAM-1) on endothelial cells, a protein involved in vasoocclusion, has not been previously investigated. We therefore measured (soluble) sVCAM-1 and zinc in 76 SCD(More)
A large opencast gold mining company in Africa had just completed a feasibility study for the expansion of the operations. A traditional net present value project valuation methodology had been used that showed a very positive net present value (NPV). The project team had conducted a qualitative risk assessment that identified and logged all potential(More)
