P-11: Differential Expression of mRNA Aromatase in Ejaculated Spermatozoa from Infertile Men in Relation to either Asthenozoospermia or Teratozoospermia
Background Estrogens biosynthesis in ejaculated spermatozoa is an autonomous process that may influence sperm functions. The purpose of this study was to evaluate the relationship between the expression of aromatase, sperm quality and seminal neutral α–glucosidase marker in semen of Tunisian infertile men. MaterialsAndMethods Fifty seven men were investigated: they were composed of two groups: ...
متن کاملBenefits of Either Operative or Non-Operative Treatment for Perilunate Dislocation and Fracture Dislocations
Dear Editor We read the article by Bagheri et al with great interest (1). We found the study interesting and comprehensive as four groups of patients, including operative and nonoperative in either pure dislocation or fracture dislocation, were compared in terms of Mayo wrist score, Grip strength, range of motion and radiographic parameters. It seems that the results were comparable to studies ...
متن کامل2 Either/Or
This essay surveys the varieties of disjunctivism about perceptual experience. Disjunctivism comes in two main flavours, metaphysical and epistemological. Metaphysical disjunctivism is the view usually associated with the disjunctivist label, and whenever ‘disjunctivism’ occurs here unprefixed, it refers to this view. After some initial discussion of (metaphysical) disjunctivism (sections 1–3),...
متن کاملA Model of Irreversible Electro-Oxidation Inhibited by Either Adsorption or Surface Complexation of the Product
Theoretical models of irreversible electro-oxidation of dissolved reactant giving dissolved product on the stationary planar electrode are developed for the conditions of staircase cyclic voltammetry. In the first model it is assumed that the product is adsorbed on the electrode surface and that the adsorbate prevents the transfer of electrons. In the second model it is assumed that the electro...
متن کاملCYCLIC NUCLEOTIDES CONTROL DIFFERENTIATION OF HUMAN MONOCYTES INTO EITHER HIGHLY ACCESSORY CELLS OR MACROPHAGES
Human peripheral blood monocytes have been found to undergo a transitory state of high accessory activity before they fully become macrophages. Time kinetics were done to follow this accessory potential. Studying the regulation of accessory activity, we have found that monocyte derived accessory cells (m-AC) pass through two phases of development, both of which are adversely controlled by ...
