Estrogen is a key factor to induce the sexually dimorphic nucleus (SDN) in the preoptic area (POA) of the rat brain. Identification of estrogen-dependent signaling pathways at SDN in POA during the critical period is a prerequisite for elucidating the mechanism. In the present study, we treated female rats with/without 17β-estradiol (E2) at birth,(More)
OBJECTIVE This study aimed to clarify the reasons why clinical otosclerosis, a very common disease among Caucasians, is not prevalent among Japanese.

BACKGROUND There are currently no effective therapeutic methods for locally recurrent, metastatic, or progressive radioactive iodine (RAI)-refractory differentiated thyroid cancer. However, multitargeted tyrosine kinase inhibitors (TKIs) such as lenvatinib or sorafenib have been approved for patients with RAI-refractory differentiated thyroid cancer as a(More)
OBJECTIVE The purpose of the current study was to research the pathogenesis of bony destruction of cholesteatoma. STUDY DESIGN We conducted a case report. SETTING The study was performed at Fukushima Medical University. PATIENTS The first case involved a 21 trisomy, whereas the second case was cancer of the hypopharynx. Both cases showed(More)
We examined 395 temporal bones with an intact tympanic membrane to explore the relationship between residual inflammation in the middle ear cavity and development of mastoid pneumatization. Histopathological changes were studied in the middle ear cavity. Mastoid pneumatization was classified as good or poor based on the extent of mastoid tip development to(More)
There are numerous reports on microfissures in the round window niche area, but not many reports have appeared on microfissures in the oval window niche area. In addition, few studies have compared microfissures between the oval and round window niche areas in the same subjects. Hence, the present study investigated the prevalence of microfissures in both(More)
