(n.) Any one numerous species of small brush-tongued parrots or lories, found mostly in Australia, New Guinea and the adjacent islands, with some forms in the East Indies. They are arboreal in their habits and feed largely upon the honey of flowers. They belong to Trichoglossus, Loriculus, and several allied genera.
Example Sentences:
(1) n. is described from the rainbow lorikeet, Trichoglossus haematodus, in Papua New Guinea.
(2) Thirteen out of 30 wild lorikeets (43.3%) were infected with E. haematodi.
(3) Between September 1977 and November 1978, chlamydiosis (psittacoisis) was diagnosed in 52 of 128 parrots, 5 of 12 cockatiels, 2 of 5 cockatoos, 3 of 6 macaws, 1 of 22 conures, 2 of 18 lovebirds, and 6 of 76 parakeets; 2 lories and 1 lorikeet were chlamydiosis negative.
(4) Plasma corticosterone concentrations in cockatoos, macaws, Amazon parrots, conures, and lorikeets before and after ACTH administration indicated that the ACTH stimulation test could be used to evaluate adrenal secretory capacity in psittacine birds.
Rosella
Definition:
(n.) A beautiful Australian parrakeet (Platycercus eximius) often kept as a cage bird. The head and back of the neck are scarlet, the throat is white, the back dark green varied with lighter green, and the breast yellow.
Example Sentences:
(1) Pregnant ewes and their fetuses were chronically catheterized using aseptic procedures under general anaesthesia, and the ewes were then fed either lucerne chaff alone, or lucerne mixed with dried plant material obtained from one of three forb species, Tribulus terrestris (caltrop), Abelmoschus ficulneus (native rosella) or Ipomoea lonchophylla (cowvine), from 103-112 days gestation until term.
(2) Descending spinal pathways have been described in 'non-dextrous' avian species (chickens, ducks, geese and pigeons), and the purpose of this study was to determine if there are any differences in the origins of descending projections to the spinal cord in 'dextrous' or prehensile parrots (sulphur-crested cockatoo, Cacatua galerita, and eastern rosella, Platycerus eximius).
(3) Certain disturbances in formation of the ON and in the internal membrane of the optic vesicle (future retina) under effect of x-rays in the dose of 2.24 Gy have been detected during the intrauterine period of development--folds, rosellas of retina, retardation in differentiation of the retina nervous layer, aberration of the ON growth with a subsequent reduction, the ON hypo- and aplasia, retardation in formation of neural sheaths, absence of intraspace between the sheaths.
(4) It was established that the active rosettes [correction of rosellae] in the patients with myocardial infarction were significantly less than in the controls (p less than 0.05).
(5) This yeast was not isolated from droppings of 13 small parrots, 10 eclectus parrots, 13 rosellas, 21 cockatiels, 6 Polytelidus sp., 32 Cacatua sp., 13 Carduelis sp., 5 waxbills, 5 starlings, 120 chicken, 9 turkeys, 2 geese, 2 Turdus sp., 1 duck and 1 gull.
(6) By means of the electron scanning microscope, structure of the olfactory rosella has been investigated in 5 species of marine Teleostei.
(7) However, ingestion of rosella seed was associated with a significantly greater fall of fetal arterial pO2 with advancing gestation, and ingestion of either rosella or cowvine was associated with significantly lower fetal mean arterial pressure at 127-131 days, compared with the Tribulus and lucerne groups.
(8) Among the species investigated variability in number and arrangement is observed in the olfactory rosella folds.
(9) Plaque-purified and non-plaque-purified velogenic viscerotropic Newcastle disease viruses (VVNDVs) were inoculated into golden-mantled rosellas (Platycercus eximius).
(10) RSL-1 and -2, isolated from diseased rosellas, were propagated in chicken embryo fibroblasts and CK cells, and were found similar to other herpesviruses in physicochemical and morphological properties.
(11) Increasing amount of cells in the transplants takes place only at the expense of neuroepithelium; its reorganization results in a peculiar rearrangement of cells with formation of so called rosellas with numerous mitotically dividing cells.
(12) Owing to this growth the differentiating cells migrate from the rosellas radially, unlike their layer-by-layer organization in the control.
(13) Eight viruses were isolated in embryonating eggs, from psittacine birds comprising a cockatiel, a budgerigar, 3 parrots, a love bird, and 2 rosellas.
(14) Simultaneously, in the spleen of the animals a decrease in the number of cells, forming rosellas with sheep erythrocytes and inhibition of their temperature resistivity have been noted.
(15) In the transplant, unlike the normal embryonal histogenesis, neuroepithelial cells make groups of rosellas.
(16) The aim of the investigation is to study the influence of human myocardium myosin on the quantitative values of T-lymphocytes examined as active rosettes [correction of rosellae] in patients with ischemic heart disease.
(17) A significant inhibiting action of the human myocardium myosin on the active rosettes [correction of rosellae] was manifested (p less than 0.002).
