Increased Fos immunoreactivity in astrocytes in the raphe pallidus under hypoxia, not hypercapnia

Kouki Kato, Risa Serizawa, Takuya Yokoyama, Nobuaki Nakamuta et autres

The raphe pallidus (RPa), a part of the caudal medullary raphe nucleus, has been suggested to participate in respiratory regulation. Therefore, hypoxia and hypercapnia are expected to affect the expression of Fos, a marker of cellular activation, in the RPa; however, there …

Fos expression in A1/C1 neurons of rats exposed to hypoxia, hypercapnia, or hypercapnic hypoxia

Kouki Kato, Risa Serizawa, Takuya Yokoyama, Nobuaki Nakamuta et autres

The distribution of Fos expression in catecholaminergic neurons with immunoreactivity for dopamine β-hydroxylase (DBH) of the ventrolateral medulla was compared between rats exposed to hypoxia (10 % O 2 ), hypercapnia (8 % CO 2 ), and hypercapnic hypoxia (8 % CO …

Osteogenesis imperfecta with repeated simultaneous bilateral proximal tibial epiphyseal injuries caused by minor trauma: A case report and literature review

Kumiko Yotsuya, Tatsuya Yasuda, Kaoru Yamazaki, Junichiro Sarukawa et autres

INTRODUCTION: Proximal tibial epiphyseal injuries are rare, accounting for 0.5-3 % of all epiphyseal injuries, of which bilateral cases are extremely rare. Only five cases of bilateral proximal tibial epiphyseal injuries have so far been reported in patients with osteogenesis imperfecta. We …

Vesicular nucleotide transporter‐immunoreactive type I cells associated with P2X3‐immunoreactive nerve endings in the rat carotid body

Takuya Yokoyama, Yoshio Yamamoto, Masato Hirakawa, Kouki Kato et autres

ATP is the major excitatory transmitter from chemoreceptor type I cells to sensory nerve endings in the carotid body, and has been suggested to be released by exocytosis from these cells. We investigated the mRNA expression and immunohistochemical localization of vesicular nucleotide …

Establishment and Characterization of a Novel Human Clear-cell Sarcoma of Soft-tissue Cell Line, RSAR001, Derived from Pleural Effusion of a Patient with Pleural Dissemination

Michiyuki Hakozaki, Hirosumi Tamura, Yuu Dobashi, Aki Yoshida et autres

BACKGROUND/AIM: Clear cell sarcoma (CCS) of soft tissue is exceedingly rare and frequently exhibits aggressive behavior. Toward the goals of improving the aggressive course and poor prognosis of CCS, and establish new therapeutic methods, molecular genetic and biological characterizations of CCS are …

Different sensitivity to the suppressive effects of isoflurane anesthesia on cardiorespiratory function in SHR/Izm, WKY/Izm, and Crl:CD (SD) rats

Kouki Kato, Jun Wakai, Kazunori Ozawa, Miho Sekiguchi et autres

Isoflurane is a widely used anesthetic, but its effects with increase in inspired concentration on cardiovascular function have not yet been clarified in rodents. Additionally, there are only a few studies comparing isoflurane-induced cardiorespiratory effects between rat strains. Thus, we investigated the …
