Glomerular filtration rate (GFR) is the best indicator of renal function. GFR is usually estimated by serum creatinine or the creatinine clearance calculated on urine collected over 24 hours or with the Cockcroft formula. These methods are however limited. Serum creatinine has a very poor sensitivity and urine collection is difficult. Cystatin C is a protease inhibitor produced in a constant manner by nucleated cells. This molecule is freely filtrated by the glomerule and quite completely catabolized in the proximal tubules. Its plasmatic concentration might thus be used to estimate GFR. Presently available data allow to conclude that plasmatic cystatin C is at least as good as serum creatinine to estimate GFR. It is less sensible to changes in body mass. Its determination appears more sensitive to detect early mild changes in GFR. Reference values are presently available for the different methods of determination. Cystatin C plasma level determination is more expensive than routine creatinine plasma determination. In the absence of very significant advantages, this might explain its limited use in daily clinical practice. [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 ▲]

Inoculation with Actinomyces pyogenes and administration of prostaglandin (PG) F-2alpha were used to induce late embryonic mortality (LEM) in heifers (n = 8) on Days 30-38 of pregnancy in order to compare the profile for bovine pregnancy associated glycoprotein 1 (PAG1), progesterone and 15-keto-13,14-dihydro-PGF(2alpha) (PGFM). Two pregnant heifers were used as controls. Inoculation into the uterine body caused LEM, as established by ultrasonography in each heifer within 24 h of treatment. When the inoculum was injected into the first part of the cervix, LEM occurred in one of two heifers (Heifer A) between 48 and 72 h after treatment. Similarly, PGF(2alpha) treatment caused LEM in three of four heifers. In six of eight heifers, PAG1 started to decrease steadily when it was accompanied by the subsequent death of the embryo. Inoculation through the cervix caused luteolysis in three of four heifers within 6-10 days after induction. After induction of LEM, PGFM concentrations showed a two to 3.8 fold increase in three of four heifers during the following six days, and from that time changed within normal ranges. The results of this study indicate that a PAG1 assay may provide an alternative method to ultrasonography for determining LEM in the cow. [less ▲]

The poplar wood has been largely used (frame – carpentry packing – paper pulp – sabot manufacture – furniture – rotary peeling for panels and packaging). Some uses of the past were progressively abandoned for tropical species or softwood. But the poplar is now largely used for the rotary peeling process, where its characteristics are appropriated and appreciated. The products not suitable for rotary peeling are used for packaging and ships for panel industry. In the past inside the important wooded areas was never considered as an valuable species while it was used in areas of small forests. Indeed for products with little added value the transportation costs become paramount and in such a case the production of poplars outside large forests become an advantage. A better knowledge of its capabilities during the various stages of its transformation and of its behaviour under various treatments has made it possible to look for new markets so as to enlarge the possibility of use.

Benign familial neonatal convulsions (BFNC) is a rare autosomal dominant generalized epilepsy of the newborn infant. Seizures occur repeatedly in the first days of life and remit by approximately 4 months of age. Previously our laboratory cloned two novel potassium channel genes, KCNQ2 and KCNQ3, and showed that they are mutated in patients with BFNC. In this report, we characterize the breakpoints of a previously reported interstitial deletion in the KCNQ2 gene and show that only KCNQ2 is deleted. We identify 11 novel mutations in KCNQ2 and one novel mutation in the KCNQ3 potassium channel genes. In one family, the phenotype extends beyond neonatal seizures and includes rolandic seizures, and a subset of families has onset of seizures in infancy. In the Xenopus oocyte expression system, we characterize five KCNQ2 and one KCNQ3 disease-causing mutations. These mutations cause a variable loss of function, and selective effects on the biophysical properties of KCNQ2/KCNQ3 heteromultimeric channels. We report here the first dominant negative mutation in KCNQ2 that has a phenotype of neonatal seizures without permanent clinical CNS impairment. [less ▲]

Lactating dairy cows with a mature corpus luteum (CL) (diameter of greater than or equal to17 mm determined by ultrasonography) and having a follicle with a diameter of 10 mm (n = 49) were randomly assigned to three groups. The first group was treated with a single dose of exogenous prostaglandin (25 mg), while the second group was treated with 35 mg on day 0, and the third group served as control in order to evaluate the effect of rectal manipulation on the CL during ultrasonographic examination. Blood samples were collected daily for analysing progesterone (P4) concentrations. In group 1 the incidence of oestrus and artificial insemination (AI) in 10 days after treatment was 95% (19 of 20). The conception rate was 31.6%, and the average time to oestrus after treatment was 3.7 day. In group 2 the incidence of oestrus and A.I. was 84.2% (16/19). The conception rate was 31.2%, and the average time to oestrus after treatment was 2.8 day. In the untreated group only two cows (2/10) exhibited oestrus during the examined period and none of them became pregnant. There were no significant differences between the two treated groups in terms of reduction in the area of CL and P4 concentrations and of an increase in the area of the dominant follicles. At the same time, the decrease in the percentage changes relative to the area of CL and to the concentrations of P4 were statistically significant in both treated groups. [less ▲]

Prolactin (PRL) promotes tumor growth in various experimental models and leads to prostate hyperplasia and mammary neoplasia in PRL transgenic mice. Increasing experimental evidence argues for the involvement of autocrine PRL in this process. PRL receptor antagonists have been developed to counteract these undesired proliferative actions of PRL. However, all forms of PRL receptor antagonists obtained to date exhibit partial agonism, preventing their therapeutic use as full antagonists. In the present study, we describe the development of new human PRL antagonists devoid of agonistic properties and therefore able to act as pure antagonists. This was demonstrated using several in vitro bioassays, including highly sensitive assays able to detect extremely low levels of receptor activation. These new compounds also act as pure antagonists in vivo, as assessed by analyzing their ability to competitively inhibit PRL-triggered signaling cascades in various target tissues (liver, mammary gland, and prostate). Finally, by using transgenic mice expressing PRL specifically in the prostate, which exhibit constitutively activated signaling cascades paralleling hyperplasia, we show that these new PRL analogs are able to completely revert PRL-activated events. These second generation human PRL antagonists are good candidates to be used as inhibitors of growth-promoting actions of PRL. [less ▲]

The release of mobility constraints has facilitated urban sprawl, i.e. the increasing spatial dissociation between urban cores and implantation sites of households and economic activities. The aim of this paper about the Walloon part of the Brussels metropolitan region is to analyse how housing market constraints reinforce the trend towards residential sprawl. Based on an analysis of the financial accessibility to both, the market for new housings and the market for pre-existing housings, it is here the influence of the price level decreasing with the distance from Brussels which is taken into account. Due to their limited financial resources and to this price gradient, many households are obliged to settle on remote sites in order to acquire their property goods. In relation to this phenomenon, it appears that, from a spatial as well as from a social point of view, the Brussels urban system is not able to settle the metropolitan growth on an adapted way. Indeed, new residential locations reinforce the increasing dissociation between work places and living places, which leads to a useless increase in mobility costs as well as a serious accentuation of socio-spatial segregations.
