- Abstract
Production rates of multijet hadronic final states are studied ine
+ e- annihilation at 29 GeV center of mass energy. QCD shower model calculations with exact first order matrix element weighting at the first gluon vertex are capable of reproducing the observed multijet event rates over a large range of jet pair masses. The method used to reconstruct jets is well suited for directly comparing experimental jet rates with parton rates calculated in perturbative QCD. Evidence for the energy dependene of as is obtained by comparing the observed production rates of 3-jet events with results of similar studies performed at higher center of mass energies.- Published

- Abstract
This paper presents energy distributions of the hadronic system produced in neutral-current electron-proton deep-inelastic scattering at a centre of mass energy of 296 GeV. Comparison of the results with QCD Monte Carlo models shows that QCD radiation has a strong influence on the characteristics of the final state. The data are reasonably reproduced by the Lund model based on a matrix element calculation in first order ofa
s , followed by appropriate parton showers, as well as by the colour dipole model. The HERWIG parton shower model also gives a reasonable representation of the data. Neither the first order matrix elements alone nor the Lund parton shower model, without the matrix element calculation, reproduce the data.- Published

- Abstract
This paper presents our first measurement of the F2structure function in neutral-current, deep inelastic scattering using the ZEUS detector at HERA, the epcolliding beam facility at DESY. The data correspond to an integrated luminosity of 24.7 nb−1. Results are presented for data in range of Q2from 10 GeV2to 4700 GeV2and Bjorken xdown to 3.0 × 10−4. The F2structure function increases rapidly as xdecreases.

6. The influence of central noradrenergic function on 5-HT2-mediated head-twitch responses in mice: Possible implications for the actions of antidepressant drugs

- Abstract
Abstract: This study has investigated the influence of central noradrenergic function on 5-HT
2 -mediated head-twitch responses in mice. Central injection of low doses of the α1 -adrenoceptor agonists phenylephrine or methoxamine, or peripheral administration of the antagonist prazosin had no effect on the head-twitches induced by 5-methoxy-N,N-dimethyltryptamine (5-MeODMT). High doses of both α1 -adrenoceptor agonists and antagonists markedly inhibited this response. Head-twitches induced by 5-MeODMT were potently inhibited by low doses of the α2 -adrenoceptor agonist clonidine, and potentiated by the antagonists idazoxan and yohimbine. Clonidine also potently inhibited this response when produced by 5-hydroxytryptophan (5-HTP) and carbidopa. The action of the β-adrenoceptor agonist clenbuterol on head-twitches was paradoxical, this drug enhancing the responses to precursor loading (5-HTP/carbidopa) but inhibiting those induced by direct agonists (5-MeODMT, quipazine). Lesioning noradrenergic neurons by central injection of 6-hydroxydopamine (6-OHDA) or peripheral administration of DSP-4 resulted in enhanced head-twitch behaviour. 6-Hydroxydopamine lesioning did not alter the inhibition of head-twitch responses by clonidine but prevented their enhancement following withdrawal from repeated desmethylimipramine (DMI) administration. It is therefore suggested that head-twitch behaviour may be under tonic control by a population of α2 -adrenoceptors which are not on presynaptic noradrenergic terminals, but are postsynaptic and located “down-stream” of the 5-HT2 receptor. In addition, the enhancement of this behaviour produced by withdrawal from repeated DMI administration probably also resulted from alterations in central noradrenergic function.- Published

- Abstract
We report on the characterization of an AC-coupled, double-sided silicon strip detector, with fast binary readout electronics, in a pion beam before and after proton irradiation. The proton irradiation was non-uniform and to increase the damage the detector was heated to accelerate the anti-annealing. The effective radiation level was about 1/spl times/10/sup 14/ p/cm/sup 2/. Both the bias voltage of the detector and the threshold of the discriminator of the binary readout electronics were varied, and the efficiencies were determined. The irradiated detector clearly shows the effect of bulk inversion. The binary system proved to be efficient well below the full depletion voltage on the p-n junction side. Due to the highly non-uniform irradiation, the depletion voltage changes from close to zero to about 120 V along a single strip, but the detector appears to work without any noticeable failures.

- Abstract
Primary aldosteronism (PA), in which there is excessive and autonomous adrenal production of aldosterone, accounts for around 5–10 of hypertension. PA may be unilateral (usually aldosterone-producing adenoma APA) or bilateral (usually adrenal hyperplasia). Recently, somatic mutations in KCNJ5 (encoding a potassium channel) have been detected in about 40 of surgically removed APAs. The aim of this study was to screen for additional somatic mutations in KCNJ5 in a cohort of APAs removed from 87 Australian patients.
