Timing of intermittent seminal HIV-1 RNA shedding in patients with undetectable plasma viral load under combination antiretroviral therapy.

It was demonstrated that combination antiretroviral therapy (cART) reduces the HIV-1 viral load (VL) in the blood and the seminal compartment. Some studies have reported that the seminal HIV-1 VL is undetectable in individuals with an undetectable blood plasma viral load (bpVL) under cART. However, some recent studies have demonstrated that seminal HIV-1 RNA may still be detected, and potentially infectious, even in the case of an undetectable bpVL.

[The process of X inactivation in the mouse].

X chromosome inactivation (XCI) is an excellent model for studying how epigenetic marks are initiated during early embryogenesis. XCI is an essential process that takes place in females, leading to dosage compensation between males and females. In mouse, it occurs in two waves: the first one is paternally imprinted, during the preimplantation period and the second one occurs in a random fashion.

[Pregnancy predictive factors in case of double embryo transfer during "Top Quality" attempts].

Objectives: To identify IVF±ICSI pregnancy predictive factors during "Top Quality" attempts in case of double embryo transfer.

Patients And Methods: Three years retrospective study (2007, 2008 and 2009) on parameters and results obtained during IVF±ICSI defined as "Top Quality" attempts: first or second attempts on less than 35years old women (age inferior or equal to) with one or two "Top Quality" embryo transfer.

Results: In case of double embryo transfer, pregnancy predictive factors are (OR [IC 95%], P): average endometrial thickness on start (4.

[Professional Practice Evaluation: How to improve quality management in procreation centers?].

Objectives: The Professional Practice Evaluation (PPE) is at the heart of quality management in procreation centers. Hereby, we report 3 years of EPP in Cytogenetics and Reproduction laboratory in Amiens University Hospital.

Patients And Methods: This PPE is based upon prospective analysis of in vitro fertilization techniques regarding two major parameters: clinically in improving embryo transfer and biologically by determining fecundation levels.

Physiopathology of human embryonic implantation: clinical incidences.

Embryo implantation consists of a series of events promoting the invasion of the endometrium and then the uterine arterial system by the extra-embryonic trophoblast. In order for this semi-heterologous implantation to succeed, the endometrium has to first undergo a number of structural and biochemical changes (decidualization). The decidua's various constituents subsequently play a role in the embryonic implantation.

[Ovarian stimulation and follicular puncture risks].

The ovarian stimulation and the follicular puncture in ART present risks which must be planned in order to better prevent them. These complications are the ovarian hyperstimulation syndrome, the thromboembolic and carcinologic risks; the anaesthetic, hemorrhagic and infectious risks of the punctures. The presence of an endometrioma can generate an increase in the infectious risk.

Nonpenetrating deep sclerectomy: a 6-year retrospective study.

Purpose: Nonpenetrating trabeculectomy, also called nonpenetrating deep sclerectomy (NPDS), is a filtering surgery where the internal wall of Schlemm's canal is excised, allowing subconjunctival filtration without actually entering the anterior chamber. This, technique was developed to minimize the complications of trabeculectomy. The authors investigated its safety and efficacy in a retrospective noncomparative study.

Ocular hypotensive efficacy and safety of once daily carteolol alginate.

Background/aim: Carteolol is a beta adrenoceptor antagonist used topically to reduce intraocular pressure, typically twice daily. In an effort to provide a once daily dosing regimen, carteolol was formulated with 1% alginic acid. The objective of this study was to evaluate the efficacy and safety of carteolol alginate solution in comparison with standard carteolol solution.

[Bioavailability of antiglaucoma drugs].

The biodisponibility of antiglaucoma drugs, generally delivered in an aqueous eye-drop solution depends on their capacity to cross the cornea. The structure of the cornea forms a barrier to strongly lipophilic substances and the continuous renewal of the lacrimal film creates a major obstacle, preventing active substances from penetrating the eye. Active substances must thus be delivered in highly concentrated solutions.

[Rapid Tendency Oriented Perimeter (TOP) with the Octopus visual field analyzer].

Purpose: To study the capabilities of a new perimetric strategy with the Octopus visual field analyzer: the Tendency Oriented Perimetry.

Methods: Tendency oriented perimetry (TOP) attempts to assess the visual field by using answers to questions to establish thresholds in the neighboring area. We evaluated 79 visual fields with the Octopus strategy using the program 32 and the TOP strategy split into the following groups: normal visual field or glaucoma suspects (52), moderately advanced glaucoma (16), advanced glaucoma (11).

Comparative evaluation of efficacy and safety of ciprofloxacin and norfloxacin ophthalmic solutions.

The efficacy and safety of ciprofloxacin ophthalmic solution 0.3% and norfloxacin ophthalmic solution 0.3% in the treatment of bacterial conjunctivitis and blepharitis were compared in a double masked randomised study.

Non-penetrating deep sclerectomy (NPDS) with or without collagen device (CD) in primary open-angle glaucoma: middle-term retrospective study.

Unlabelled: The purpose of this study is to evaluate the middle-term tonometric results of a new filtering procedure, the nonpenetrating deep sclerectomy with or without collagen device, in primary open-angle glaucoma. This technic aims to eliminate or minimize the complications of classical trabeculectomy.

Method: This procedure was carried out by Koslov and colleagues.

[Non-penetrating deep sclerectomy combined with a collagen implant in primary open-angle glaucoma. Medium-term retrospective results].

Purpose: To evaluate the middle term tonometric results of a new filtering procedure, the non penetrating deep sclerectomy with collagen device, in primary open-angle glaucoma. This technique aims to eliminate or minimize the complications of classical trabeculectomy.

Material And Method: This procedure has been developed by Koslov et al.

Effectiveness and Tolerance of beta-Blocker/Pilocarpine Combination Eye Drops in Primary Open-Angle Glaucoma and High Intraocular Pressure.

Objective And Method: A randomized, double-blind, parallel-group study compared the effectiveness and tolerability of three treatments for glaucoma: 2% carteolol/2% pilocarpine fixed-ratio combination (CBS 341A) twice a day, versus a 0.5% timolol/2% pilocarpine fixed combination twice a day versus 2% carteolol twice a day and 2% pilocarpine three times a day. The treatment period lasted 2 months.

Comparison of apraclonidine and timolol in chronic open-angle glaucoma. A three-month study.

Purpose: To compare the safety and efficacy of apraclonidine ophthalmic solution 0.25% and 0.5% (both given 3 times daily) to timolol maleate (0.

[Clinical evaluation of betaxolol in ophthalmic suspension with or without preservative agent in patients with glaucoma or ocular hypertension].

A prospective, randomized, cross-over, double-blind trial was designed to compare the safety and intraocular pressure (IOP) lowering effect of betaxolol 0.25% ophthalmic suspension with and without preservative (benzalkonium chloride). Twenty-seven patients with primary open angle glaucoma or with ocular hypertension were assigned randomly to receive either the preserved or the unpreserved unit dose betaxolol suspension first, followed by the second medication after a 7-10 day washout period.
