(7) This enzyme was ultrahistochemically localized throughout the membranes of the caecal epithelium as well as extracellularly, i.e., within pre-exuvial calcareous concretions and postexuvial calcified spherules.
(8) This fluid begins to disappear from the exuvial space approximately 9-10 h before the actual shedding of the integument.
(9) Acetazolamide treatment in vivo inhibited about 50% of the calcium uptake during both pre-exuvial secretion and postexuvial reabsorption.
(10) We argue that the potassium salt solution, formed in the exuvial space (as water presumably follows the actively transported potassium), has three functions (1) to accomplish the gel--sol transformation, (2) to activate the gel enzymes and (3) to buffer the enzyme solution at a pH favourable to the activity of the gel enzymes.
(11) The exuvial side of the pharate pupal integument is usually positive to the haemolymph-side, both in vivo and in vitro, during the period when the moulting fluid is being secreted.
(12) In a normal 32 mM KHCO3 saline, potential difference (PD) is around 10 mV, exuvial side positive, and short-circuit current (SCC) is 15-20 microA cm-2.
(13) Their level is maximum at the time of the exuviation.
(14) This formation associated with a diplosome goes through the duct cell and ends up in the exuvial space.
(15) The ratio of potassium flux toward the exuvial space is higher than that toward the haemolymph, under both open-circuit conditions and short-circuit conditions, demonstrating by the Flux Ratio test that potassium is actively transported across the isolated integument during this secretion period.
Molt
Definition:
(n.) Alt. of Moult
() imp. of Melt.
(v. t.) Alt. of Moult
(v. t.) Alt. of Moult
Example Sentences:
(1) In Experiment 1 (summer), hens regained body weight more rapidly, returned to production faster, and had larger egg weights (Weeks 1 to 4) when fed the 16 or 13% CP molt diets than when fed the 10% CP molt diet.
(2) After molting, resulting nymphs (n = 74) were fed on susceptible mice.
(3) The MT-2, derived from an adult T-cell leukaemia (ATL) cell, the Molt-4F, a human T-cell line, and the Isk, an EB virus-transformed B-cell line, were found to have high-affinity receptors for somatostatin, a cyclic tetradecapeptide that inhibits the release of substances such as growth hormone, TSH, glucagon, insulin, secretin, gastrin and cholecystokinin.
(4) The demonstration of cAMP-dependent protein kinase and of VIP- and PHI-mediated protein phosphorylation in Molt 4b lymphoblasts provides evidence on a molecular level for neuropeptide modulation of human lymphocyte function.
(5) The ability of various gangliosides to inhibit the cytotoxic activity of natural killers (NK-cells) from Syrian hamsters towards human lymphoma MOLT-4 cells was studied.
(6) Measurements were made at the imaginal molt and on fed and crowded imagos at 10, 20 and 30 post-imaginal days.
(7) A comparison between primary cells and resulting cell lines showed that the cell lines established from patients with T-ALL (MOLT 12, 13, 14 and MOLT 16, 17) expressed similar phenotypes and isoenzyme patterns, but were different in a few specific aspects.
(8) At the culmination of each molt, the larval tobacco hornworm exhibits a pre-ecdysis behavior prior to shedding its old cuticle at ecdysis.
(9) 2'-Deoxycytidine (10 microM) also blocked dGTP accumulation in MOLT-4 cells.
(10) Cytotoxicity resulting from dUMP misincorporation was consistent with the enhanced toxicity of piritrexim which was observed when HL-60 cells or MOLT-4 cells were exposed concurrently to exogenous deoxyuridine.
(11) Molting occurred in almost all kinds of organs examined.
(12) Syncytium formation between HUT-78 cells persistently infected with human immunodeficiency virus type 1 (HIV-1) and uninfected CD4-bearing MOLT-4 or CEM cells results in a rapid destruction of the MOLT-4 or CEM cells.
(13) Furthermore these cells exhibited cytotoxic activity against several tumour cell lines including the syngeneic L1210, the TNF-insensitive P815 mastocytoma, the human MOLT-4 lymphoblastic leukaemia, as well as the murine TNF-sensitive L929 fibroblast cell line.
(14) Second instar larvae which survive the molt exhibit a marked reduction in growth and eventually die as small second instar larvae.
(15) These lines of evidence were in accord with previous accounts of the so-called "molt inhibiting hormone" (MIH) effect.
(16) The objective of this study was to determine the molting process of Dirofilaria immitis third-stage larvae (L-3) to fourth-stage larvae (L-4), as it occurred in vitro.
(17) Injections of ovine prolactin during the pause-inducing procedure significantly reduced the subsequent rate of loss of primary wing feathers, suggesting that in certain physiological states, PRL may function to suppress molting.
(18) 1-beta-D-Arabinofuranosyl-E-5-(2-bromovinyl)uracil (BV-araU) and E-5-(2-bromovinyl)uracil, a metabolite of BV-araU, did not affect either the anti-human immunodeficiency virus activity or the cytotoxicity of azidothymidine in MT-4 and MOLT-4 cells.
(19) After the L1 molt, energy metabolism in animals destined to become dauer larvae diverges from that of animals committed to growth.
(20) Thus, one may deduce that stopped larvae could have low levels of ecdysone, and perhaps these are the ultimate physiological cause of their arrested development before the critical larva-pupa molt.
