Abstract We exposed mature Japanese medaka ( Oryzias latipes ) to 4‐nonylphenol (4‐NP) elucidate its reproductive effects and estrogenic responses. For each treatment, eight breeding pairs were for 3 weeks at measured 4‐NP concentrations of 24.8, 50.9, 101, 184 μg/L. Egg production the during third week exposure (15–21 d) was significantly decreased in ≥101‐μg/L treatment group, fertility 184‐μg/L group. Induction testis–ova observed male fish all concentrations, whereas abnormality...
The present study examined the effects of tributyltin (TBT), polychlorinated biphenyls (PCBs), and mixtures both chemicals on reproduction in Japanese medaka, Oryzias latipes. For 21 d we gave groups medaka freeze-dried brine shrimp flakes contaminated with a mixture either 0, 1, 5, or 25 microg TBT g(-1) plus 0 .micro PCBs g(-1). We measured fecundity fertility parent fish assessed deformity, hatchability, time-to-hatching, swim-up failure rate next generation. Fertilization success third...
Abstract Diatoms are one of the most prominent oceanic primary producers and now recognized to be distributed throughout world. They maintain their population despite predators, infections, unfavourable environmental conditions. One smallest diatoms, Chaetoceros tenuissimus , can coexist with infectious viruses during blooms. To further understand this relationship, we sequenced C. strain NIES-3715 genome. A gene fragment a replication-associated from ssDNA virus (designated endogenous...
We examined the overflow of endogenous norepinephrine with electrical stimulation, associated pressor response, and rate initial neuronal uptake [3H]norepinephrine in perfused mesenteric arteries 7- 13-week-old spontaneously hypertensive rats (SHR) Wistar-Kyoto (WKY) rats. The tissues two rats, a WKY control rat, were simultaneously processed subjected to same stimulation. Both absolute fractional during periarterial nerve stimulation (5 10 Hz for 1 minute) tissue 7-week-old SHR was...
