A series of quaternary salt derivatives of 2-[(hydroxyimino)methyl]-1-methylimidazole incorporating various side chains bearing ether, silyl, nitrile, ester, halogen, nitro, sulfone, amino, or aminosulfonyl substituents was prepared and evaluated in vivo for the treatment of anticholinesterase intoxication. Test results in the mouse revealed that the type(More)
Several quaternary imidazolium oxime derivatives incorporating side chains bearing nitro, sulfone, amino, and aminosulfonyl substituents were prepared and evaluated as treatment therapeutics for anti-AChE intoxication. In vivo test results in the mouse revealed that many of these compounds are highly effective in providing life-saving protection against the(More)
OBJECTIVE To investigate whether the location and extent of the CT hyperdense artery sign (HAS) at presentation affects response to IV alteplase in the randomized controlled Third International Stroke Trial (IST-3). METHODS All prerandomization and follow-up (24-48 hours) CT brain scans in IST-3 were assessed for HAS presence, location, and extent by(More)
Identifying research users, applications, and impact is important for research performers, managers, evaluators, and sponsors. Identification of the user audience and the research impact is complex and time consuming due to the many indirect pathways through which fundamental research can impact applications. This paper identified the literature pathways(More)
OBJECTIVE 1. To audit the management of cervical carcinoma in the South West Region with the aim of identifying and addressing deficiencies. 2. To determine whether recent NHS restructuring has affected the provision of cancer care. DESIGN Retrospective review of hospital case notes. SETTING All hospitals in the South West Region of England.

In the search for improved lipophilic centrally active acetylcholinesterase (AChE) antidotes, a series of alpha-keto thiohydroximates were prepared and evaluated for their ability to reactivate AChEs inhibited by ethyl p-nitrophenyl methylphosphonate (EPMP) and soman (GD). The compounds conformed to the general structure 4-RC6H5C-(O)C(NOH)S(CH2)nN+R'R''.X-(More)
We prepared six pairs of alpha-heteroaromatic aldoximes, RC(= NOH)H, and thiohydroximates, RC(= NOH)S-(CH2)2N(C2H5)2, where R represents various oxadiazole and thiadiazole rings. Each compound was characterized with respect to the following: structure, (hydroxyimino)methyl acid dissociation constant, nucleophilicity toward trigonal carbon and tetrahedral(More)
OBJECTIVE To evaluate the present management of muscle-invasive bladder cancer in the South West Region and to assess the workload resulting from the rationalization of treatment in specific centres. METHODS A retrospective survey was undertaken in all the hospitals in the South West Region, to assess the management of all patients presenting with(More)
