(1) At midclimax, adult and larval RBCs were separated on a Renografin continuous density gradient.
(2) Replication patterns of the larval salivary gland chromosomes were compared after pulse labeling with 3H-thymidine and autoradiography.
(3) Larvae of both mutants also excrete 3H-3-hydroxykynurenine and 3H-kynurenine rapidly, which probably accounts for the normal levels of kynurenine during larval life.
(4) These data suggested that an inter-thymic exchange of cells did not occur during larval life.
(5) The test is based on the ability of larvae to freely migrate through selected mesh sizes of nylon sieves and the reduced ability of larvae to migrate after preincubation with, and in the presence of, substances that inhibit or reduce larval motility.
(6) During the first 15 to 20 min of metamorphosis the larval arms are retracted and resorbed into the aboral surface of the juvenile.
(7) Dose-response experiments showed that lower concentrations of both ivermectin and closantel were not as effective in reducing larval growth.
(8) Skin grafts from Xenopus isogeneic to the donors of the MHC-incompatible larval and adult thymus implants are always tolerated by Tx hosts.
(9) pipiens disappeared in larval habitats by December but An.
(10) Radioimmunoassay using this antibody showed that these proteins are induced in the hemolymph in response to injury of the larval body wall.
(11) We detail the fatty acid compositions of last larval instars of two lepidopterans, Spodoptera frugiperda and Trichoplusia ni, two tissues from T. ni, a cell line derived from each species and the respective larval and cell culture media.
(12) Larval growth in vitro was significantly inhibited by alpha 2M and AT III (P less than 0.05) when compared to albumin controls but was not affected by alpha 1PI.
(13) Therefore, in the cricket cercal sensory system, both regeneration of the central synapses following axotomy of the presynaptic sensory neurons and the normal rearrangement of connectivity during larval development appear not to require axonal action potentials.
(14) The histochemical activities of succinic dehydrogenase (SDH) and Ca++-activated ATPase (pHs 7.4 and 9.4) were studied in the larval tail musculature of Rana japonica, Rana catesbeiana and Rana ornativentris.
(15) The heads were examined for adult and larval meningeal worms (Parelaphostrongylus tenuis) by physical examination of the brain surfaces, and the Baermann technique, respectively, and for ear mites by examination of ear scrapings.
(16) Adhfn46 adults and larvae accumulate abundant ADH-like distal (adult) and proximal (larval) transcripts that are shorter than transcripts in wild-type flies by a lesion located in the second ADH protein-coding exon.
(17) Larval populations from the three rivers were genetically distinct.
(18) The seasonal abundance pattern of larval I. persulcatus on four small mammal species appears as a bimodal peak (June and September), but nymphal I. persulcatus has a monomodal peak during spring.
(19) The neotenic urodelan amphibian species model represents actually the only model in which the coexistence of larval (or neonatal) and adult heavy chains is maintained throughout life in adults.
(20) Modifications have also arisen in proportions of the embryo fated to become various cell types and larval structures.
