-
(1984)Adult rats were tested for step-down passive avoidance following exposure to either water contaminated with CoCl₂ (Group Co) or uncontaminated distilled water (Group X). Behavioral analysis included acquisition and retention ...
-
(1982)Many hormones appear to affect the development of the embryonic central nervous system (CNS), causing either gross morphological defects or subtle changes in the functional maturation of neurons which are manifested as ...
-
(Texas A&M University, 2013-02-22)In every criminal case, the selection of jurors is a crucial factor in determining the outcome of the trial. The prosecution and the defense each attempt to construct a jury that will be sympathetic to their arguments. ...
-
(1995)This study focused on the visual search strategies adopted by a sample of 328 five through eight year olds. Developmental trends in children's search efficiency were systematically related to their general metacognitive ...
-
(1989)Humans and laboratory animals experience a decline in immune system function and DNA excision repair correlated with increased occurrence of cancer as a function of age. Dietary restriction is reported to be associated ...
-
(1980)Ruminants comprise the most valuable class of animals to mankind. The grazing habits of both wild and domestic ruminant animals within a given ecosystem are of considerable environmental significance, and the efficiency ...
-
Effects of Experience and Meaningfulness on Learning and Memory in a Sensory Restricted Environment (1984)This study examines two previously untested conditions in a sensory restricted environment: meaningfulness and experience. Meaningfulness was measured by employing three different levels of learning material. The learning ...
-
(1985)Cattle implanted with Ralgro (zeranol) or Synovex-S (estradiol/progesterone, 20:200, w/w) reach finishing weight sooner than controls. Further, it is generally agreed that this increase in weight cannot be attributed to ...
-
(Texas A&M University, 2013-02-22)The European fallow deer (Dama dama dama) is an exotic animal species that originated in Europe and Asia and was brought to Texas in 1930. The European fallow deer was initially introduced as a farmed animal to be used ...
-
(1982)Juvenile hormone (JH), a sesquiterpene compound, acts as a morphogenetic hormone in insects; JH permits expression of the larval genome and inhibits expression of the adult genome. Previous experiments have indicated that ...
-
(1996)We discuss the progress that we have had in studying the effects that lateral confinement has in the electronic bandstructure of a superlattice, and consequently, on its current-voltage characteristics. This study has been ...
-
The Effects of Leptin Antagonist on Hypothalamic Neuropeptide Y Circuitry in Infantile Male Lambs. (2012-04-16)It is proposed that leptin signaling during infantile development is critical for structural organization of hypothalamic circuitry involved in the control of food intake and energy expenditure. The present study tested ...
-
(Texas A&M University, 2013-02-22)The semiconductor manufacturing industry is increasingly using copper to design and fabricate faster and smaller integrated circuits. Despite copper's electrical advantages, few ways exist to deposit it uniformly into the ...
-
(1985)Three foliage species, Brassaia arboricola, Brassaia actinophylla, and Dracaena marginata, were evaluated for growth and quality in a simulated interior environment for six weeks. They were planted in each of four growing ...
-
(1987)This Undergraduate Fellows program focused on establishing a link between mental stress and changes in the heart’s electrical activity. Electrocardiograms were taken before and after a stressful event (a lab quiz). Examining ...
-
(1979)Relatively little is known about the stress response in invertebrates or how to measure it. Hyperglycemia (high blood sugar) has been recommended as a possible indicator of stress in animals. The degree of stress effects ...
-
(1978)Nitrogen dioxide and nitrite toxicity were investigated using lactate dehydrogenase and pyruvate kinase as indicators of cell damage. Lung tissue enzyme levels were concurrently studied to assess enzyme release. No change ...
-
(1994)The effects of low level lead (Pb) exposure in culture for 3 days on the non-specific ATPase activity of rat C6 glioma cells was studied. Cells were incubated in media containing Pb acetate at a concentration of 10⁻⁶M, ...
-
(2012-04-18)This study examines genetic diversity in two species of sipunculan worm, Phascolosoma agassizii and Themiste pyroides, in the Sea of Japan. Low sea levels of the Pleistocene era partially or completely isolated marginal ...
-
(Texas A&M University, 2013-02-22)This study examined the effects of developmental cadmium exposure on morphine-induced locomotor activity. Adult female rats were exposed to 0 ppm, 25 ppm and 50 ppm cadmium via an adulterated food source for 30 days prior ...
