(1) To investigate the adaptive responses of immature bone to increased loads, young (3-wk-old) White Leghorn roosters were subjected to moderately intense treadmill running for 5 or 9 wk.
(2) A single mRNA of 1.3 kb was detected at high levels in heart and brain of 10-week-old roosters, and, at lower levels in spleen, liver and skeletal muscle.
(3) Reports of neurotoxic agents causing adverse effects on the male reproductive system initiated the present study which was designed to examine the effects of TOCP on the rooster.
(4) In the roosters the kidney contained approximately five times as much Se as the muscle.
(5) A recent re-determination of the rooster protamine amino acid sequence (28 residues from the N terminus) matches that predicted from the genome rather than the sequence of Nakano et al.
(6) We also show, by indirect immunofluorescence studies, that the 60-kDa protein is antigenically conserved in the germ cells of grasshopper, rooster, and frog and in plant meiocytes.
(7) Testis, epididymis and ductus deferens of the adult domestic fowl and male gonads of juvenile roosters have been studied by means of histochemical and histological methods.
(8) Another man in a pirate hat covered in voodoo dolls approached the screen, placing a live rooster on the stage as if offering it to the football gods.
(9) Consequently, the abnormal seminal plasma composition of Sd roosters is attributed to excurrent duct dysfunction.
(10) We report here the production of a fertile rooster which lacks avian leukosis virus-related endogenous viral genes and which seems to be completely normal and healthy.
(11) Oligomers of hyaluronic acid were prepared by digestion of hyaluronic acid from rooster combs with testicular hyaluronidase (hyaluronate 4-glycanohydrolase, EC 3.2.1.35), leech head hyaluronidase (hyaluronate 3-glycanohydrolase, EC 3.2.1.36), and with fungal hyaluronidase (hyaluronate lyase from Streptomyces hyalurolyticus).
(12) Radioactive O-phosphoryl-L-serine was detected after alkaline deacylation of rat and rooster liver [(3)H]seryl-tRNA acylated in vitro with homologous synthetases.
(13) Ribosomal RNAases from control and estrogen-stimulated roosters show differences in response to Mg2+, spermidine and EDTA.
(14) Visual cues thus appear to be more important than auditory cues alone with respect to the maintenance of dominant social status in roosters.
(15) Consequently, for an estrogenized rooster, the addition of both heparin and yeast RNA to the homogenate suffices to stabilize the polysomes, whereas control rooster liver homogenate needs supplementation with endogenous ribonuclease inhibitor.
(16) Aggressive and passive roosters displayed agonistic behaviour towards each other.
(17) Moreover, the maximal amplitude of the stapedius muscle EMG response is consistently lower than that detected in young roosters, despite the fact that the maximal vocalization amplitude of the adult birds is much higher.
(18) cDNA clones were prepared from poly(A)+ mRNA isolated from a population enriched in postmeiotic rooster testes spermatogenic cells.
(19) However, when these hens were artificially inseminated with semen from mite infested roosters, fertility nor hatchability was affected by the mite infestation.
(20) It was concluded that LMET was the major methionine analogue excreted from roosters dosed with either HMB-FA or LMET, and that HMB-FA was not excreted by the avian kidney.
