Endoscopic visualisation of the round window during cochlear implantation
The Journal of Laryngology & Otology, 2020AbstractBackgroundEndoscopes provide a magnified view of the middle ear and visualisation of hidden areas. Otoendoscopes facilitate excellent visualisation of the round window niche during cochlear implantation.ObjectiveTo compare microscopic and endoscopic visualisation of the round window membrane during cochlear implantation in 20 patients ...

NF‐κB Activation at Implantation Window of the Mouse Uterus
American Journal of Reproductive Immunology, 2004Problem: Nuclear factor kappa B (NF‐κB) is one candidate transcriptional modulator, which might regulate many kinds of molecules that play sequential roles at implantation in the endometrium. However, temporal and spatial activation of NF‐κB at implantation window is unknown.Methods: Activation of NF‐κB in the mouse uterus was determined by ...

Surgical anatomy of the round window—Implications for cochlear implantation
Clinical Otolaryngology, 2018BackgroundThe round window is an important portal for the application of active hearing aids and cochlear implants. The anatomical and topographical knowledge about the round window region is a prerequisite for successful insertion for a cochlear implant electrode.Objective of reviewTo sum up current knowledge about the round window anatomy and to give

Bailliere's clinical obstetrics and gynaecology, 1992
The implantation window is defined as that period when the uterus is receptive for implantation of the free-lying blastocyst. This period of receptivity is short and results from the programmed sequence of the action of oestrogen and progesterone on the endometrium.

[Endometrial implantation window in infertility].
Arkhiv patologii, 2011The paper presents the results of biopsy and curettage specimens from 92 patients with infertility. Histological and immunohistological (steroid receptors, Ki67, P27, and cyclin E) methods and scanning electron microscopy have been used. The substantial immunohistochemical (IHC) changes found in the endometrial implantation window in infertility are ...

The Round Window Electromagnetic Implantable Hearing Aid Approach
Otolaryngologic Clinics of North America, 1995The round window electromagnetic implantable hearing aid (RWEM) approach uses a magnet surgically implanted onto the round window membrane of the cochlea to impart vibrational energy to the inner ear when driven by a nearby electromagnetic coil. In this article, experimental methods used in animal ABR studies are described for this approach and ...

Cochlear Implant Electrode Insertion: The Round Window Revisited
The Laryngoscope, 2007AbstractObjective: To examine aspects of round window (RW) anatomy that are relevant to its use as a portal for atraumatic insertion of cochlear implant electrodes.Study Design: Anatomic study using human cadaveric temporal bones.Methods: A series of 30 temporal bones was dissected to permit microscopic study of the RW region.Results: The bony ...

Determination of Endometrial Status and the Implantation Window
2004Human embryo implantation normally takes place between days 20 and 24, or between days LH +7 and LH +11 of a normal conception cycle. The process begins with apposition of the hatched blastocyst to the luminal surface epithelium of the endometrium and is followed by adhesion, invasion and anchorage of the trophoblast into the endometrial stroma where ...

Cell Biological Aspects of the Implantation Window
1997“Implantation window” is a widely used and remarkably well understood term in reproductive biology and medicine. This term emerged from suggestions by Psychoyos (1963), McLaren (1973), and Finn and Martin (1974) when they asked whether estrogens in mice and rats may control the physiological status of a “sensitive” or “nonsensitive,” of a “receptive ...
