The strangulated intestinal pathologies of horses are accompanied by a local activation of the neutrophils, that can be revealed by measuring the tissular enzymatic activity of the granulocytic enzyme myeloperoxidase (MPO). To estimate the possible spreading of this neutrophil activation to the systemic circulation, we designed a radioimmunoassay (RIA) for equine neutrophil myeloperoxidase (MPO) (EC 1.11.1.7) using a specific rabbit antiserum. MPO was labeled with 1 mCi 125I by a technique of self-labeling in the presence of 10(-4) M hydrogen peroxide. The RIA was performed by incubation of 100 microl diluted antiserum, 100 microl labeled MPO (+/-30,000 cpm) and 100 microl of the reference molecule (unlabeled MPO) solution or the unknown sample, at room temperature for 18 h. The antibody-antigen complexes were isolated by double antibody precipitation. The sensitivity of the RIA was 2 ng/ml. The RIA showed good precision and accuracy with intra- and inter-assay coefficients of variation 6% and 8%, respectively, for MPO concentrations ranging from 2 ng/ml to 60 ng/ml. The best sampling technique for MPO measurement in plasma was to collect blood into EDTA, which allowed us to get a plasmatic value stable with time. The mean MPO value in normal horses was 69.5 +/- 19.4 ng/ml in EDTA anticoagulated plasma (n = 48). The stress of transport and anaesthesia did not modify the mean plasmatic value of MPO. No significant increase of plasma MPO was observed in 17 horses submitted to surgery for pathologies without systemic impact. But, in 25 horses with obstructive intestinal pathologies, persistent abnormal MPO concentrations were measured (until 740 ng/ml). [less ▲]

We previously identified the ZNF85 (HPF4) KRAB zinc finger gene, a member of the human ZNF91 family. Here, we show that the ZNF85 gene is highly expressed in normal adult testis, in seminomas, and in the NT2/D1 teratocarcinoma cell line. Immunocytochemical localization of a panel of beta-Gal/ZNF85 fusion proteins revealed that ZNF85 contains at least one nuclear localization signal located in the spacer region connecting the KRAB domain with the zinc finger repeats. Bacterially expressed ZNF85 zinc finger domain bound strongly and exclusively to DNA in vitro in a zinc-dependent manner. The KRAB(A) domain of the ZNF85 protein and of several other members of the ZNF91 family exhibited repressing activity when tested in Gal4 fusion protein assays. The repression was significantly enhanced by the addition of the KRAB (B) domain, whereas further addition of other conserved regions had no effect. The ZNF85 KRAB(A) and (B) domains in vitro bound several nuclear proteins that might constitute critical cofactors for repression. [less ▲]

Galloping on power lines is a difficult matter. In this paper a galloping has been reproduced in a wind tunnel on a section of an actual conductor with actual ice shape. Aerodynamics is first detailed. Then flutter type and Den Hartod type galloping has been obtained in the wind tunnel depending on changeable ratio vertical to torsional frequencies. [less ▲]

The simplest conceivable event that can occur at the gene level can result in the development of efficacious resistance tot antibiotics. The bacterial world behaves as an enormous organism whose cells can exchange their genes very easily. Accordingly, oppotunities for the exhcange of genetic material in nature are probably unlimited. This knowledge cannot be ignored. It leads to the important conclusion that the antibiotics are societal drugs. A resistance gene which has appeared somewhere in the world can travel far and fast.

The aim of this study was to determine cardiac contractility using indices derived from cardiac catheterisation in conscious healthy dogs during dobutamine infusion. Eight dogs were studied. An ECG was recorded together with left ventricular pressure and volume which were measured using a conductance catheter with an integrated microtip pressure sensor. Eight indices of left ventricular systolic performance were derived from these records. Measurements were realised under basal conditions and during an incremental dobutamine challenge. The maximal rate of rise in ventricular pressure (max dP/dt), max dP/dt divided by the developed pressure and the mean systolic ejection rate were the most sensitive indices to detect dobutamine induced changes in contractility with maximal percentage changes of 122+/-11 per cent, 130+/-7 per cent and 102+/-24 per cent respectively. Ejection fraction increased significantly during dobutamine infusion (maximal percentage change of 43+/-9 per cent) whereas the pre-ejection period (PEP) and the left ventricular ejection time (LVET) decreased significantly (maximal percentage change of -41+/-2 per cent and -28+/-3 per cent respectively). All these six indices were significantly correlated with each other. Conversely, the ratio PEP/LVET and the LVET corrected for heart rate dependency showed a maximal percentage change of only -10+/-1 per cent and -16+/-7 per cent, respectively, during the dobutamine infusion and were not significantly correlated with the other contractility indices. This study demonstrated the feasibility of the conductance method to determine cardiac contractility in conscious healthy dogs submitted to a pharmacological stress testing and provides control values for eight indices of left ventricular contractility during dobutamine infusion at increasing dosages.

Sought to determine whether promoting context-dependent sensitization might facilitate expression of sensitization in preweanlings. Sprague-Dawley rats were injected daily from postnatal day 14 to postnatal day 20 with 0, 5, 15, or 30 mg/kg cocaine hydrochloride and placed for 30 min in either the experimental chamber or home cage. On postnatal day 21 (test day), Ss were challenged with either 15 mg/kg cocaine or saline prior to placement in the experimental chamber. Significant sensitization of cocaine-induced stereotyped head movements was evident in animals given 15 or 30 mg/kg chronically in the experimental chamber, but not when these same doses were given in the home cage. Less consistent evidence for cocaine-induced sensitization was seen when examining locomotion, although trends for sensitization of this behavior were seen in animals chronically injected in either the test chamber or home cage. Thus, preweanlings can exhibit cocaine sensitization, particularly in terms of stereotypy, when tested shortly after the chronic exposure period, with expression of this sensitization being facilitated by pairing the chronic injections with the test context.
