In our mutation analyses of bilirubin UDP glycosyltransferase (UGT1A1) gene, we encountered six patients with Crigler-Najjar syndrome type II who were double homozygotes for G71R and Y486D, a patient with Gilbert's syndrome who was a single homozygote for G71R and six patients with Gilbert's syndrome who were single heterozygote for G71R. To clarify the(More)
OBJECTIVE The incidence of nonphysiologic neonatal hyperbilirubinemia is twice as high in East Asians as in whites. We studied whether the condition was associated with mutations in the gene for bilirubin uridine 5'-diphosphate-glucuronosyltransferase (UGT1A1), a key enzyme of bilirubin catabolism. DESIGN We analyzed the UGT1A1 gene in 25 Japanese(More)
Dielectric dispersion measurements over a frequency range 0.01-100 MHz were made with the suspensions of a cultured cell line, mouse lymphoma L5178Y, and an attempt to explain the observed dielectric behavior by taking explicitly into consideration the possible involvement of cell nucleus has been presented. The use of a conventional "single-shell" model in(More)
The membrane potentials and resistances of L cells were measured using a standard electrophysiological technique. The values obtained in physiological media were around--15 mV and 37Momega, respectively. Almost all the large nondividing L cells (giant L cells) showed spontaneous oscillations of the membrane potential between around -15 and -40 mV.(More)
Light and electron microscopy were performed in a study of the effects of electrical stimulation upon the reparative processes in flexor tendons cultured in vitro. After one or two weeks of incubation, the unstimulated control tendons were covered with fibroblastic surface cells, thought to have originated from the epitenon. In contrast, the tendons(More)
We measured IgA1 and IgA2 subclass antibody levels against human type I, II, III and IV collagens in patients with ankylosing spondylitis (AS) by enzyme linked immunosorbent assay (ELISA). Significant elevations of IgA1 antibodies against type II collagen (p < 0.01) and IgA2 antibodies against type I (p < 0.001), III (p < 0.001), and IV (p < 0.01) collagens(More)
We report a case of Gilbert syndrome caused by a homozygous missense mutation (Tyr486Asp) of the bilirubin UDP-glucuronosyltransferase gene. Homozygous missense mutations of the gene have previously been recognized as responsible for Crigler-Najjar syndrome type II. We conclude that Gilbert syndrome in some patients results from homozygous missense(More)
