A deletion mutation causes hemophilia B in Lhasa Apso dogs.
Hemophilia B is a bleeding disorder caused by a deficiency of clotting factor IX (FIX). A colony of FIX deficient Lhasa Apso dogs has been established and the molecular basis of hemophilia B has been determined. The plasma factor IX levels were < 1% of normal canine levels in affected dogs. A complex deletion mutation at nucleotides 772-777 was found when hepatocyte cDNA from a hemophilia B dog...
متن کاملNormal Values of Standard Full Field Electroretinography in Healthy Subjects in Northern Iran
Background: Electroretinography (ERG) is known as a diagnostic test for evaluating the performance of different layers of the retina. Its normal values maybe different in different populations. Objectives: Determining the normal values of ERG parameters in patients presenting to an ophthalmologic center in Guilan in northern Iran. Materials and Methods: Fifty-five people presenting to a teach...
متن کاملFull-field electroretinogram recorded with skin electrodes in normal adults.
Purpose: Alternative recording methods have been tested to allow the electroretinogram (ERG) recording in uncooperative patients and/or patients with palpebral alterations, including recordings with skin electrodes. The purpose of this study was to compare ERG recorded with skin electrodes and well-established microfiber electrodes and to determine normative values of ERG parameters for recordi...
متن کاملstandard full field electroretinography: normal values and variations with age in an iranian population
purpose: to determine normal values of standard full field electroretinography (erg) and to evaluate variation with age in an iranian population. methods: the amplitudes and implicit times of ergs from 170 normal subjects aged 1 to 80 years were recorded according to the international society for clinical electrophysiology of vision. study participants included subjects who refered to our clini...
متن کاملNormal S cone electroretinogram b-wave in Oguchi's disease.
AIM The short wavelength sensitive (S) cone electroretinograms (ERGs) were examined in two patients with Oguchi's disease to study S cone function. METHODS Ganzfeld colour flashes under bright white background illumination were used to elicit S cone, and mixed long (L) and middle (M) wavelength sensitive cone ERGs. RESULTS The S cone ERG b-wave was normal with short wavelength stimuli with ...
