(18) The cellular and circuit properties of individual identified neurons in invertebrates can be readily studied; hence it is possible to determine how the complex properties of nerve cells function in the generation of behavior.
(19) These processes may be conserved in a wide range of invertebrates and vertebrates.
(20) The action of ocular screening pigments of vertebrates (melanins) as well as those of invertebrates (ommochromes) on lipid peroxidation has been studied.
Palp
Definition:
(n.) Same as Palpus.
(v. t.) To have a distinct touch or feeling of; to feel.
Example Sentences:
(1) The GRC bound to immobilized histones could be eluted with PALP, but not with its related compounds, such as pyridoxamine, pyridoxamine 5'-phosphate, pyridoxal, and pyridoxine, suggesting a specific effect of PALP.
(2) The lobus glomeratus receives inputs from the maxillary palps and also from processess of deutocerebral neurons.
(3) Lon-directed degradation of SulA was energy dependent, as was the increase in degradation of SulA in delta lon pAlp+ cells.
(4) Paper electrophoretic analysis showed that in the mixture of TOB and PALP, the spot corresponding to TOB alone almost disappeared and the spot associated with TOB overlapped with that associated with PALP, although the spots of TOB alone and PALP alone were observed as single spots on the cathode and anode sides, respectively.
(5) The activated glucocorticoid-receptor complexes (GRC) from rat liver bind tightly to histone (from calf thymus)-agarose and cannot be eluted with 3 M KCl or 50% ethylene glycol, but can be eluted with 20 mM pyridoxal 5'-phosphate (PALP).
(6) Physiologically, the palp-pit receptors respond uniformly; they are most excitable by stimulation with carbon dioxide while they exhibit relatively moderate responses to various odorants.
(7) Testing of MAb binding to bacteria showed that a part of the BLp I, PALp I, and PALp II sites was immunoaccessible in intact homologous bacteria, and that the Hm I and Hm II epitopes were inaccessible.
(8) It is suggested that there may be an instability of the PALP-albumin complex in this condition.
(9) A gonadotropic inhibition is observed by means of oothecal production in Periplaneta americana after unilateral amputation of the mandible, the maxillary palp and the labial palp, in females reared with males at emergence.
(10) Similar assays with males deprived of maxillary palps make it unlikely that the basiconic-like sensilla on these appendages are needed to perceive the attraction pheromones.
(11) If used together with a myoma drill, large holes can be punched into tumours, making them for the first time well palp-able and revolvable.
(12) When aspartate- and alanine transaminase (AST and ALT, respectively) activities were studied in homogenates of rat cerebellum, brain cortex and brain stem (using a modified procedure by Raitman and Frenkel), addition of 50 microM pyridoxal-5-phosphate (PALP) increased 2-3-fold the activity studied.
