Glutamate receptors may play a critical role in the refinement of developing synapses. The lateral superior olivary nucleus (LSO)-medial nucleus of trapezoid body (MNTB) synaptic transmission in the mammalian auditory brain stem mediate many excitatory transmitters such as glutamate, which is a useful model to study excitatory synaptic development. Hearing deficits are often accompanied by chan...

Hairpin-tail (T(hp)) is a new allele of brachyury on chromosome 17 (linkage group IX) of the mouse. The morphological effects in the heterozygote are on the notochord and the tail. The homozygous abnormal is unknown. T(hp) is unique in that the phenotype of the heterozygote seems to depend on the source of the T(hp) gene. If it is inherited via the egg the phenotype is extreme and death follows...

Cytogenetic studies were performed on 150 cases of Down's syndrome (DS) in Iran. The standard trisomy 21 was found in 132 (88 % ) and translocation-trisomy 21 (+21) in 18 (12%) patients, i.e., t(21,21) in 1(0.63%) and mosaicism in 17(11.33%) cases. The comparison of the frequencies for mosaicism between different populations such as Denmark, Hungary, Egypt, Iraq, India, Australia and Iran ...

Abstract This research is the first to produce induced pluripotent stem cell-derived inner ear sensory neurons in Neurog1 +/? heterozygote mouse using blastocyst complementation. Additionally, this approach corrected non-sensory deficits associated with heterozygosity, indicating that complementation specific endogenous function. work validates use of as a tool create novel insight into functio...
