The significance of microanatomy of the round window in terms of cochlear implantation

Vestnik otorinolaringologii, 2021
Sensoneural hearing loss is a polyetiological disease, which is often a secondary reflection of systemic pathology and is associated with damage of the cochlea and auditory nerve receptors. An important point in the surgical stage of cochlear implantation is the introduction of an implant active electrode into the cochleostomy spiral channel through ...

Laminectomy and Spinal Cord Window Implantation in the Mouse

Journal of Visualized Experiments, 2019
This protocol describes a method for spinal cord laminectomy and glass window implantation for in vivo imaging of the mouse spinal cord. An integrated digital vaporizer is utilized to achieve a stable plane of anesthesia at a low-flow rate of isoflurane. A single vertebral spine is removed, and a commercially available cover-glass is overlaid on a thin

Imaging Window Device for Subcutaneous Implantation Tumor

2018
Most of preclinical cancer studies use xenograft models established from human cell lines or patient-derived cancer cells subcutaneously implanted into the flank of immunocompromised mice. These models are often assumed to represent the original diseases and are valuable tools, at least to some extent, for understanding both the basic biology of cancer

NF‐κB Activation at Implantation Window of the Mouse Uterus

American Journal of Reproductive Immunology, 2004
Problem:  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 ...

The implantation window.

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, 2011
The 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 ...

Surgical implantation of an abdominal imaging window for intravital microscopy

Nature Protocols, 2013
High-resolution intravital microscopy through imaging windows has become an indispensable technique for the long-term visualization of dynamic processes in living animals. Easily accessible sites such as the skin, the breast and the skull can be imaged using various different imaging windows; however, long-term imaging studies on cellular processes in ...

Evaluation of round window accessibility to cochlear implant insertion

European Archives of Oto-Rhino-Laryngology, 2012
Emphasis on hearing preservation has led to recognition of the round window membrane (RWM) as a portal for the cochlear implant electrode array. The St Thomas' Hospital (STH) classification was devised to evaluate the accessibility of RWM electrode insertion.
