| susceptibility of cultured juveniles of several marine fish to the sevenband grouper nervous necrosis virus. | piscine nodaviruses (betanodaviruses) have been tentatively divided into four genotypes (sjnnv, rgnnv, tpnnv and bfnnv) and it is suggested that host specificity is different among these genotypes. in the present study, a betanodavirus [sevenband grouper nervous necrosis virus (sgnnv)] belonging to the redspotted grouper nervous necrosis virus (rgnnv) genotype, to which most betanodaviruses from warm water fish are identified, was evaluated for its pathogenicity to hatchery-reared juveniles of s ... | 2003 | 12962219 |
| seasonal changes in the humoral immune response and the lymphoid tissues of the marine teleost, sebastiscus marmoratus. | seasonal modulation in antibody production in relation to the state of lymphoid tissue development was studied in the ovoviviparous fish, s. marmoratus. animals were kept in tanks with running seawater at 23 +/- 1 degrees c for a minimum 2 week acclimatization period and then immunized three times at 2 day intervals with 20% srbc (5 microliters/g body weight) intraperitoneally. immunized fish were bled 2 weeks after the first injection at the time of peak response and plasma were analyzed for ti ... | 1986 | 3765343 |
| sonic motor nucleus and its connections with octaval and lateral line nuclei of the medulla in a rockfish, sebastiscus marmoratus. | the sonic motor nucleus and its fiber connections were examined in a rockfish, sebastiscus marmoratus by means of tracer methods using horseradish peroxidase (hrp), biocytin, and carbocyanine dye (dii). sebastiscus has a swimbladder and a pair of extrinsic sonic/drumming muscles. the sonic muscle is ipsilaterally innervated by the occipital nerve which is composed of two ventral roots arising from the sonic motor nucleus. the sonic motor neurons are distributed in the most ventral part of the ve ... | 1999 | 10592382 |
| area dorsalis pars lateralis of the telencephalon in a teleost (sebastiscus marmoratus) can be divided into dorsal and ventral regions. | area dorsalis pars lateralis was shown to be subdivided into a dorsal region and a ventral region by a shallow groove on the telencephalic surface. in the dorsal region, three layers were distinguished by nissl staining; a surface layer i, a middle layer ii, and a deep layer iii. although a three-layered structure was also observed in the ventral region, it was not as clear as that in the dorsal region. cells in area dorsalis pars lateralis were classified by golgi-cox staining into 5 types; sma ... | 1996 | 8955962 |
| characteristics of established ksg cells derived from the scorpionfish sebastiscus marmoratus: what happens under the hydrostatic pressure like the deep sea? | advances in cell biology depend, partly, on the development of new cell lines and culture methods. our research focused on a fibroblast-like cell line, "ksg," which is derived from scorpionfish fin tissue (sebastiscus marmoratus). cells were grown in leibovitz's l-15 medium with 10% fetal bovine serum following standard procedures. the optimum growth temperatures for these lines ranged from 15°c to 25°c. all cells survived storage for at least 3 yr at -80°c. subsequently, they were continuously ... | 2014 | 24399253 |
| tissue-specific and embryonic expression of the retinoid x receptors in sebastiscus marmoratus. | retinoid x receptors (rxrs) are highly conserved members of the nuclear receptor family and mediate various physiological processes in vertebrates. most studies on rxrs have concentrated on their structure and function in mammals and their characterization and developmental expression in danio rerio. however, there is little information concerning the distribution of rxrs in teleost tissues. in the present study, we cloned partial sequences of three rxr subtypes (rxra, -b, -g) from sebastiscus m ... | 2009 | 19555773 |
