There is a complex functional organization of the central auditory system from the brainstem to primary and associative auditory cortices. Functional neuroimaging has been used to visualize and confirm the spatial distribution of brain activation in temporal areas for the processing of simple acoustic stimuli. Brain activity is much more complex for words, and different networks can be recruited when phonological, lexical and semantic levels of processing are engaged. [less ▲]

An acute respiratory attack with bronchospasm is associated with excessive stimulation of the parasympathic nervous system. It may be reduced by administration of anticholinergic agents. Atropine and ipratropium bromide have been tested. This study is to evaluate the efficacy of the synthetic antimuscarinic compound glycopyrrolate as a bronchodilator in horses. Respiratory crisis was induced in seven allergic horses by exposure to natural allergens. Prior to the study, it was established that the attack could be stopped using intravenous atropine sulphate. Pulmonary function tests (ventilation and arterial blood gas analysis) were performed on the horses before and then after aerosol administration of 1500 µg of glycopyrrolate (Robinul®). The attack was characterised by an increase in total pulmonary resis¬tance and maximum pleural pressure variation and by decreased compliance. This study demonstrates that glycopyrrolate exhibits affects that are just as rapid and effective as intravenous atropine or aerosol administration of 1200 µg dry powder Ipratropium. In addi¬tion the treatment was well tolerated and no side-effects were observed in contrast to those seen with intravenous administration of atro¬pine. Therefore this drug has an important role to play among the therapeutics available to practitioners for acute respiratory attacks in horses [less ▲]

We present calculations of the optical absorption spectra of clusters SiH 4, Si 10H 16, Si 17H 36, Si 29H 24, and Si 35H 36, as determined from two different methods: the Bethe-Salpeter equation (BSE) with a model dielectric function, and the time-dependent density-functional theory within the adiabatic local-density approximation (TDLDA). Single-particle states are obtained from local-density approximation (LDA) calculations and, for the BSE calculation, a quasiparticle gap correction is provided by quantum Monte Carlo calculations. We find that the exchange-correlation kernel of the TDLDA has almost no effect on the calculated spectra, while the corresponding attractive part of the electron-hole interaction of the BSE produces enhanced absorptive features at low energies. For the smallest cluster SiH 4, the two methods produce markedly different results, with the TDLDA spectra appearing closer to the experimental result. The gross features of the TDLDA and BSE spectra for larger clusters are however similar, due to the strong repulsive Coulomb kernel present in both treatments [less ▲]

A chronic consumption (3.5 months) of ergot (Claviceps purpurea) contaminated triticale in dairy cows resulted in dyspnea, mainly expiratory, consistent with interstitial pneumonia and emphysema. These troubles can be compared to many observations done in humans after long lasting treatments with ergot derivatives [less ▲]

Numerous studies have been directed towards the synthesis of early-late heterobimetallic complexes. Surprisingly, only few reports have been reported about their catalytic behaviour. However, their potential in homogeneous catalysis is enormous. Indeed, a co-operative work by the two metal centres in the complex may lead to new catalytic systems with unique reactivity. <br /> <br />The Dijon’s team has concentrated their efforts on the synthesis and study of heterobimetallic complexes in which both metal fragments are known for their catalytic activity. Titanocenes are of considerable interest as catalysts for the polymerisation of a-olefins. The catalytic performance of RuCl2(arene) complexes (1) has been demonstrated in different reactions, including olefin metathesis and atom transfer radical polymerisation (ATRP). In attempts to examine such type of catalytic systems, complexation of bent titanocene metallo-ligands by the [RuCl2(p-cymene)]2 dimer is currently investigated. [less ▲]

BACKGROUND: It is commonly stated that risk factors for postoperative nausea are the same as for vomiting. The authors designed a prospective study to identify and differentiate the risk factors for postoperative nausea and vomiting in various surgical populations in a clinical audit setting. METHODS: The study included 671 consecutive surgical inpatients, aged 15 yr or more, undergoing various procedures. The study focused on postoperative nausea visual analog scale scores every 4 h and vomiting episodes within 72 h. Both vomiting and retching were considered as emetic events. Patient-, anesthesia-, and surgery-related variables that were considered to have a possible effect on the proportion of patients experiencing postoperative nausea and/or vomiting were examined. The bivariate Dale model for binary correlated outcomes was used to identify selectively the potential risk factors of postoperative nausea and vomiting. RESULTS: Among the 671 patients in the study, 126 (19%) reported one or more episodes of nausea, and 66 patients (10%) suffered one or more emetic episodes during the studied period. There was a highly significant association between the two outcomes. Some risk factors were predictive of both nausea and vomiting (female gender, nonsmoking status, and general anesthesia). History of migraine and type of surgery were mainly responsible for nausea but not for vomiting. The predictive effect of risk factors was controlled for postoperative pain and analgesic drugs. CONCLUSION: This study shows that differences exist in risk factors of postoperative nausea and vomiting. These could be explained by differences in the physiopathology of the two symptoms. [less ▲]

Histone deacetylases (HDACs) are involved in the regulation of transcription and their inhibitors are a promising class of new anticancer drugs. We have previously reported Boc(Ac)Lys-AMC, also termed MAL, as a fluorescent substrate for HDACs. Now we present a modification of MAL called Z-MAL that is characterized by an increased rate of conversion by histone deacetylases of classes I and II and the recently discovered sirtuins (histone deacetylases class III). MAL and Z-MAL are the first nonradioactive substrates for class III enzymes. The new substrate Z-MAL allows for shorter assay times in inhibitor screening and is applicable to diverse sources of deacetylase activity even with completely different catalytic mechanisms. Interestingly, MAL shows some relative preference toward class II, indicating that subtype selectivity in small-molecule HDAC substrates might be obtained. [less ▲]
