New tarif tables are constructed in order to give foresters the possibility of appraising merchantable volumes based upon varying limits of utilization. The method uses regression functions which take into account specified top limits defined in girth and log length. This study is applied to the beech (Fagus sylvatica, L.). [less ▲]

L'évolution des coûts de santé en général, et hospitaliers en particulier, a conduit les autorités belges à prendre des mesures pour limiter les durées de séjour. Les hôpitaux étant à présent financés en fonction du nombre d'admissions et des pathologies correspondantes, l'usage d'un outil permettant d'estimer la proportion des admissions et des journées inappropriées, ainsi que leurs causes, est d'un intérêt majeur. Trois enquêtes transversales successives ont été menées de 2003 à 2005 dans 23 hôpitaux aigus en médecine interne, chirurgie et gériatrie. En tout, 12 000 séjours et 1 800 admissions ont ainsi été audités au moyen de l'Appropriateness Evaluation Protocol. [less ▲]

Experiments aimed at determination of the character of the gold observed in a copper ore processed by flotation, and also to evaluate the possibilities of improvement of the total gold recovery have been carried out. The gravity equipment used was a 7.5" Knelson screen hydrostatic concentrator, reported of being capable of treatment and upgrading of up to 1000 times raw material with about 30% hypothetical concentration of heavy flotation sized particles. The gold-to-sulfides ratio obtained during the various runs was chosen as a general criterion for the type of gold presented (free or locked) and for the gravity approach feasibility. [less ▲]

The feasibility of two non-traditional approaches - reedbeds as a natural wetland and adsorption on lignite and its maceral fractions - for their application in metal bearing effluent treatment is discussed. The main mechanisms of metals uptake are otulined. The preliminary results from a pilot scale wetland operation for metallurgical effluents purification are analysed. For the second approach - the different maceral fractions derived from coal refining have shown different metal uptake apptitude. Zeta potential studies and adsorption isotherms have explained these findings. [less ▲]

Angiogenesis, the process of development of a new microvasculature, is regulated by a balance of positive and negative factors. We show both in vivo and in vitro that the members of the human prolactin/growth hormone family, i.e., human prolactin, human growth hormone, human placental lactogen, and human growth hormone variant are angiogenic whereas their respective 16-kDa N-terminal fragments are antiangiogenic. The opposite actions are regulated in part via activation or inhibition of mitogen-activated protein kinase signaling pathway. In addition, the N-terminal fragments stimulate expression of type 1 plasminogen activator inhibitor whereas the intact molecules have no effect, an observation consistent with the fragments acting via separate receptors. The concept that a single molecule encodes both angiogenic and antiangiogenic peptides represents an efficient model for regulating the balance of positive and negative factors controlling angiogenesis. This hypothesis has potential physiological importance for the control of the vascular connection between the fetal and maternal circulations in the placenta, where human prolactin, human placental lactogen, and human growth hormone variant are expressed.

A determinant of human T-lymphotropic virus-1 (HTLV-1)–associated myelopathy/ tropical spastic paraparesis (HAM/TSP) development is the HTLV-1–infected cell burden. Viral proteins Tax and HBZ, encoded by the sense and antisense strands of th pX region, respectively, play key roles in HTLV-1 persistence. Tax drives CD4 - cel clonal expansion and is the immunodominant viral antigen recognized by the immune response. Valproate (2-n-propylpentanoic acid, VPA), a histone deacetylase inhibitor, was thought to trigger Tax expression, thereby exposing the latent HTLV-1 reservoir to immune destruction. We evaluated the impact of VPA on Tax, Gag, and HBZ expressions in cultured lymphocytes from HTLV-1 asymptomatic carriers and HAM/TSP patients. Approximately one-fifth of proviruspositive CD4 T cells spontaneously became Tax-positive, but this fraction rose to two-thirds of Tax positive–infected cells when cultured with VPA. Valproate enhanced Gag-p19 release. Tax- and GagmRNA levels peaked spontaneously, before declining concomitantly to HBZmRNA increase. VPA enhanced and prolonged Tax-mRNA expression, whereas it blocked HBZ expression. Our findings suggest that, in addition to modulating Tax expression, another mechanism involving HBZ repression might determine the outcome ofVPAtreatment on HTLV-1–infected– cell proliferation and survival.
