OBJECTIVES To document the equine perioperative mortality rate and to highlight any factor associated with an increased risk of death up to 7 days after anaesthesia. STUDY DESIGN A prospective observational epidemiological multicentre study. METHODS Data were recorded from all equidae undergoing general anaesthesia in 62 clinics. Power calculations(More)
Aging is associated not only with oxidant stress, but also with increased interleukin-6 (IL-6) levels. To determine if oxidative stress could contribute to the age-associated increase IL-6 expression, we exposed LNCaP prostate carcinoma cells and HeLa cervical carcinoma cells to H2O2 as an oxidant challenge. We found that H2O2 induced IL-6 expression(More)
1. I n t r o d u c t i o n This paper describes the design for an operating system family called Choices being built for the Embedded Operating System (EOS) project at the University of Illinois at Urbana-Champaign. Choices embodies the notion of customized operating systems that are tailored for particular hardware configurations or for particular(More)
The Confidential Enquiry into Perioperative Equine Fatalities (CEPEF-1) is an observational multi-institutional prospective study of recovery outcome at 7 days post operatively, as called for by Steffey (1991). Data from 6,255 general anaesthetics (February 91-March 93) were submitted confidentially by 62 clinics. The outcomes of 333 cases which were(More)
REASONS FOR PERFORMING STUDY Approximately 1 in 100 horses suffer unexpectedly from anaesthetic-related death. Identification and use of the safest anaesthetic drugs should support this aim. Experimental evidence has suggested that isoflurane should be a safer maintenance agent in equine anaesthesia than halothane. HYPOTHESIS The death rate would be(More)
The postnatal structural development of the thyroid gland of the Australian native bandicoot, Isoodon macrourus, was monitored and the onset of thyroid function (i.e., the secretion of thyroid hormones) was determined. Thyroid glands were obtained from bandicoots at days 1, 3, 11, 12, 13, 21, 25, 30, 34, 35, 39, 46, 48, 50, 59, 61, 75, 79, 83, and 163 of(More)
This paper presents three principles for the design and construction of object-oriented operating systems. These principles are based on the design of Choices, an object-oriented operating system that is implemented on the Encore Multimax shared memory multiprocessor. Choices is written entirely in C++, an object-oriented language that supports inheritance(More)
The programming of the interrupt handling mechanisms, process switching primitives, scheduling mechanisms, and synchronization primitives of an operating system for a multiprocessor require both efficient code in order to support the needs of high-performance or real-time applications and careful organization to facilitate maintenance. Although many(More)
