Example Sentences:

(3) Response latencies to electrical stimulation of the optic chiasm were determined for 130 cells; no X-like cell showed a latency shorter than 1-7 ms, no Y-like cell showed a latency longer than 1-6 ms. Primate lateral geniculate nucleus cells with X-like properties thus receive their excitatory input from retinal cells with slowly conducting axons and these most probably include the tonic ganglion cells described by Gouras (1968, 1969); Y-like lateral geniculate nucleus cells are driven by retinal cells with faster conducting axons, most probably including the phasic ganglion cells described by Gouras.

(6) The experiments were repeated at several eccentricities and the results show that, for a test target and background field of the same colour and under conditions which isolate the green or red spectral response mechanism, the minimum target displacement required for motion detection appears to increase in a manner similar to the centre-width receptive-field size of broad-band, centre--surround transient neurons in the rhesus monkey retina [De Monasterio and Gouras (1975) J.
(7) The agreement between the behaviourally determined perceptive field centre sizes and the receptive field centre sizes of broadband cells (measured by DeMonasterio and Gouras 1975) is excellent.
(8) In contrast, signals from the short-wavelength-sensitive (SWS) cones and dark-adapted rod photoreceptors are thought to be carried almost exclusively by ON bipolar cells (Gouras & Evers, 1985).
Gourd
Definition:
(n.) A fleshy, three-celled, many-seeded fruit, as the melon, pumpkin, cucumber, etc., of the order Cucurbitaceae; and especially the bottle gourd (Lagenaria vulgaris) which occurs in a great variety of forms, and, when the interior part is removed, serves for bottles, dippers, cups, and other dishes.
(n.) A dipper or other vessel made from the shell of a gourd; hence, a drinking vessel; a bottle.
(n.) A false die. See Gord.
(n.) Alt. of Gourde

(3) 1. beta-Momorcharin, a glycoprotein isolated from seeds of the bitter gourd, inhibited incorporation of [3H]leucine, [3H]uridine and [3H]thymidine into trichloroacetic acid-precipitable radioactivity in peri-implantation mouse embryos, mouse splenocytes with or without activation by concanavalin A, and human squamous carcinoma of the tongue and larynx, but did not affect incorporation of the aforementioned radioisotopes into mouse liver cells.
(4) Age composition, seasonal abundance and diel patterns of landing activity of the sylvan vector of yellow fever Haemagogus janthinomys Dyar were monitored weekly during 1981-82 by human collectors on the ground at Point Gourde in Chaguaramas Forest, 16 km west of Port of Spain, Trinidad.
(5) And, if one is not at the zenith of adulation of the Pacific islanders who believe the Prince to be the penis-gourd-sporting Melanesian Messiah, then, at the very least, the example of Britain's longest-serving monarchal consort is deserving of our – and, more specifically, the Duchess of Cambridge's – interest.
(6) Many had a longer cell body and were cylindrical or gourd-like in shape, but some short hair cells were also present in the caudal saccule.
(7) Seven trypsin inhibitors were isolated from the seeds of Cucurbitaceae plants: two from cucumber (Cucumis sativus) and red bryony (Bryonia diotica) and one from figleaf gourd (Cucurbita ficifolia), spaghetti squash (Cucurbita pepo var.
(8) She spent an hour preparing a huge spread of dishes, using her own curry powder: jackfruit curry, crispy chewy aubergine, bitter gourd salad, fish balls, mango chutney and ambulthiyal – chunks of yellowfin tuna steeped in spices.
(9) The complete amino acid sequence of ribonuclease (RNase MC) from the seeds of bitter gourd (Momordica charantia) has been determined.
(10) Three new proteins which inhibit protein synthesis in rabbit reticulocyte lysates were isolated from an extract of sponge gourd (Luffa cylindrica) seeds by chromatography on a AF-Blue Toyopearl column followed by FPLC with a Mono S column.
(11) Experimental evidence indicated that the snake-gourd proteinases are similar in their properties to cucumisin, which is isolated from the sarcocarp of melon fruit.
(12) Correlations between ragweed and gourd-specific IgE levels were significant (p less than 0.001), and correlation coefficients between any two gourds exceeded 0.79.
(13) Gourde Forest, Trinidad, were monitored weekly for 53 consecutive weeks using conventional ovitraps.
(14) Luffin-a, a ribosome-inactivating protein from the seeds of sponge gourd (Luffa cylindrica), was modified with 2,4,6-trinitrobenzenesulfonic acid (TNBS) at pH 8.0 and 20 degrees C. The inhibitory activity of the modified luffin-a on protein synthesis using rabbit reticulocyte lysate was lost rapidly at a rate compatible with that of the modification of a single highly reactive amino group in the initial stage of the reaction.
