    Preoperative manual detorsion of the spermatic cord with Doppler ultrasound monitoring in patients with intravaginal acute testicular torsion (2000)

    Notes: Abstract Objective. To assess the effectiveness of preoperative manual detorsion in acute testicular torsion.¶Materials and methods. Between June 1998 and March 1999, seven patients presenting with testicular torsion underwent manual manipulation under US monitoring in order to restore the flow to the testis prior to surgery (orchidopexy). All detorsions were lateral in direction. The success of the manoeuvre was assessed both clinically and sonographically and confirmed at surgery.¶Results. Six manoeuvres were successful in restoring flow to the testis. The failed attempt in the seventh patient was due to failure to manipulate beyond an initial 1 1/2 rotations (540 °).¶Conclusions. Preoperative detorsion is the fastest way to relieve testicular ischaemia. However, manual detorsion of the spermatic cord is not a substitute for surgical exploration and bilateral orchidopexy is still necessary.

    Topics: Computer Science
    Notes: Abstract Molecular computer graphics (MCG) has become the indispensable complement of experimental chemical and biological tools and, in a way, will shape the evolution of these fields. This accelerated and popularized evolution takes root in the visual, even scenic, grasping of fundamental chemical concepts, perceived as veritable ideograms, which condense a vast amount of information with a few two- or threedimensional graphic symbols. With MCG one can carry out real computerized syntheses of chemical images. MCG is also an ideal tool through which to visualize the changes of a system as a function of time. This review article describes the potentials and advantages of structural MCG for visualizing the basic steps of important modelization concepts, particularly for handling on-line structures in information networks and in computer-assisted drug design (CADD) applications.

    Grid stage modelling functions and molecular vector graphics (1986)

    Topics: Computer Science
    Notes: Abstract A polymodelling system (POLYMOD) is presented for varied 2D or 3D displays of chemical shapes, whether structural (molecular volumes distances, surfaces...) or electronic (molecular electrostatic potential, electron densities ...). The POLYMOD system manages reversible correspondences between calculation and representation spaces by immersing the molecules studied in a unique represetation space structured by a 3D grid box. This box, called COOBOX, defined by its point internal coordinates, is used to transform other coordinates into its own. Direct multi-slice images along thex, y, z axis provide access to a variety of derived operations around a molecular shape or set of shapes disposed in various manners. Interactive sub systems ensure Boolean operations and compare property shapes through the 3D grid. Clear separation of graphic routine and of downstream modelling programs leads to rapid and original generation of varied images (subimages, direct or composite images) which are then available for simulation strategies.

    Pharmacokinetics and metabolism of hexamethylmelamine in mice after IP administration (1986)

    Topics: Medicine
    Notes: Summary The pharmacokinetics of hexamethylmelamine (HMM) and its first metabolite (hydroxymethylpentamethylmelamine HMPMM) following IP bolus dose of 200 mg/kg were studied in mice. The drug concentrations were determined by a sensitive reversed-phase HPLC assay. Thus, for the first time, HMM major hydroxylated and demethylated metabolite plasma levels canbedetermined at the same time. Pharmacokinetic data were analyzed by an original method using a nonlinear cost function minimized by a simplex algorithm. An important property of this computer program is that convergence is ensured in contrast to linear or nonlinear least-square regression analysis, which leads to lack of convergence or to false convergence. Both HMM and HMPMM data fit a one-compartment open model. The parameters obtained indicate that the parent drug would probably be rapidly and completely transformed by the human body into HMPMM.

    Pharmacokinetics and metabolism of hexamethylmelamine in mice bearing renal cell tumors (1988)

    Details

    Topics: Medicine
    Notes: Summary The pharmacokinetics of hexamethylmelamine (HMM) and its main metabolites hydroxymethylpentamethylmelamine (HMPMM), pentamethylmelamine (PMM), and 2,2,4,6 tetramethylmelamine (2,2,4,6 TetrMM) were studied in renal cell (RC) tumor tissues and plasma of CDF1 mice that had received IP bolus injections of the maximally tolerated dose (200 mg/kg) of HMM. HMM, PMM, and 2,2,4,6 Tetr MM concentrations determined in RC tissues were much higher than the plasma values, as indicated by the pharmacokinetic parameters (Cmax and AUC). On the other hand, very low levels of HMPMM, generally considered to be a potentially active antitumor compound, were detected in the target tissues, whereas this hydroxylated metabolite was stable and easily determined in plasma. High HMM concentrations in RC tissues could correlate with the high sensitivity of the tumor to this drug. However, the behavior of HMPMM remains unclear; related hypotheses are presented in this paper.

    Radiation necrosis of the brain: Time of onset and incidence related to total dose and fractionation of radiation (1985)

    Notes: Summary Clinical deterioration during or after brain irradiation may be due to progression of neoplasm or radiation induced necrosis of the neoplasm and/or of normal brain tissues, or a combination of all. Eight patients with histologically documented radiation induced lesions of the brain are included in this study. The radiation therapy included the fractional schedule, group A, who received 280 to 300 rads daily, to a total dose of 4500 to 5000 rads and weekly exposure did not exceed 900 rads. Group B patients were exposed to 850 rads, daily dose on day 1, 3, 21 and 23 to a total dose of 3400 rads. The incidence of radiation induced lesions of brain was 3.4% in patients group A and 8.7% in group B patients (without) statistical significance). The median time of onset of these lesions after completion of radiation therapy was significantly shorter in group B patients (8.5 months) as opposed to group A patients (21 months).
