    Notes: Objective To measure the plasma levels of corticotrophin-releasing hormone and corticotrophin-releasing hormone binding protein in normal pregnancy and in pregnancies complicated by pre-eclampsia.Setting John Radcliffe Hospital, Oxford and St Thomas's Hospital, London.Subjects One hundred and twenty pregnant women sampled prospectively throughout gestation, of whom 91 experienced a normal pregnancy and eight developed pre-eclampsia; in a second study, 10 women with severe pre-eclampsia, presenting at a range of gestational ages, were sampled once and compared with appropriately matched normal pregnant women.Main outcome measure Plasma levels of corticotrophin-releasing hormone determined by immunoradiometric assay. Plasma levels of corticotrophin-releasing hormone binding protein measured by direct radioimmunoassay.Results In the prospective study, plasma samples from women with pre-eclampsia exhibited higher (390.2 versus 292.7 pmol/l at 36 weeks) levels of corticotrophin-releasing hormone and significantly lower (5.24 versus 8.14 nmol/l at 36 weeks, P 0.002) levels of corticotrophin-releasing hormone binding protein than normal controls. In the second, single time point study a significant elevation in CRH (P 〈 0.002) and reduction in CRH-BP (P 〈 0.001) was found in pre-eclamptic pregnancies compared with controls.Conclusions In human pregnancies complicated by pre-eclampsia there is an elevated level of corticotrophin releasing hormone whilst there is less corticotrophin-releasing hormone binding protein; therefore there is a net increase in free potentially bioactive hormone which may play a role in the pathology of the disease.

    Notes: The impact of chronic urticaria (CU) on the quality of life is undocumented. We assessed quality of life in patients with CU, including patients with associated delayed pressure urticaria (DPU). One hundred and forty–two out–patients completed self–administered questionnaires: a disease–specific, purpose designed questionnaire, and the Nottingham health profile (NHP). Many patients reported problems attributable to their skin condition in facets of everyday life including home management, personal care, recreation and social interaction, mobility, emotional factors, sleep, rest and work. The NHP part I scores showed restriction in the areas of mobility, sleep, energy, and demonstrated pain, social isolation and altered emotional reactions. Part II of the NHP showed that patients experienced difficulties in relation to work, looking after the home, social life, home relationships, sex life, hobbies and holidays. The patients with DPU had significantly more problems with mobility, gardening and choice of clothing than the uncomplicated CU patients. They also suffered more pain, had more problems with work and were more restricted in their hobbies.

    Notes: We have studied the interaction of a high current electron beam with dielectric loaded waveguides as a source of electromagnetic radiation. A unique high current photoinjector-based electron linac was used to generate the drive beam for these experiments, and the fields generated were diagnosed using a trailing probe (witness) beam from a second photocathode gun. Traveling wave dielectric structures with luminal (vphase=c) frequencies of 15 and 20 GHz were used. The radio frequency power levels generated in these initial experiments were very large—up to 11 MW.

    Notes: Abstract: Involvement of phosphate-activated glutaminase in Huntington's disease and agonal state was investigated in caudate nucleus and frontal cortex from postmortem brains. In Huntington's disease the activities of phosphate-activated glutaminase, glutamic acid decarboxylase, succinic dehydrogenase, choline acetyl-transferase, and acetylcholinesterase were significantly reduced in the caudate nucleus, but not in the frontal cortex. The activity of phosphate-activated glutaminase, and to a lesser extent of glutamic acid decarboxylase, was reduced in cases of terminal illness, as compared with cases of sudden death. Succinic dehydrogenase and choline acetyltransferase were reduced only in the few cases of prolonged and severe terminal illness. Enzyme activities of the caudate nucleus were more affected by agonal state than were those of frontal cortex. Results indicate that phosphate-activated glutaminase could be a useful marker of neuronal damage due to agonal state, and that phosphate-activated glutaminase and succinic dehydrogenase are reduced in Huntington's disease.

    Notes: Abstract: [14C]Acetyl-CoA was found to react spontaneously with dithiothreitol to give a relatively apolar product which was readily extractable into a butanol-toluene scintillant. This technique was used in a rapid, reproducible assay for rat brain ATP:citrate lyase using [1,5-14C]citrate as substrate. The tissue extract, a 14,000 g supernatant, exhibited a lyase activity of approximately 7 nmol acetyl-CoA produced/min per mg supernatant protein, and was inhibited ≥79% by α-ketoglutaric acid (10 mm), Cu2+ (1 mm)and Zn2+(1 mm). [14C]Oxaloacetate, [14C]malate and endogenous citrate synthase were found not to interfere significantly with lyase estimations, but NADH was required in the reaction mixture to inhibit acetyl-CoA hydrolase activity.

    Notes: Temperature dependent photoluminescence decay measurements have been used to study the minority carrier dynamics in iodine-doped ZnSe grown by molecular beam epitaxy. The existence of three deep acceptor levels with energies at 80, 120, and 350 meV above the valence band has been established. The 80 and 120 meV levels have a density dependence directly related to the iodine doping density whilst the level at 350 meV does not. Significant broadband donor–acceptor emission is observed from this material and appears to be associated with the acceptor level at 350 meV. © 1995 American Institute of Physics.
