The Expression Of The Crf1 Gene In Mouse Embryonic Development, Margaret Gruber

Presidential Scholars Theses (1990 – 2006)

A mouse gene cloned in the laboratory of James and Olivia Smith at Baylor College of Medicine was found to be involved in motor function. This gene was named CRFl for Clq-Related Factor 1, and using in situ hybridization, it was found to be expressed mainly in the brainstem of adult mice. There is a gene similar to the CRFl gene in humans. By determining this gene's role in mouse development, more will be known about the development of human motor function.

To determine the stage of embryonic development at which the expression of this gene …

Intra- And Interspecific Aggregation Responses Of Locusta Migratoria Migratorioides And Schistocerca Gregaria And A Comparison Of Their Pheromone Emissions, Abdoulaye Niassy, Baldwyn Torto, Peter G.N. Njagi, Ahmed Hassanali, Daniel Obeng-Ofori, Jonathan N. Ayertey

All Peer-Reviewed Publications

Gregarious nymphs of Schistocerca gregaria and Locusta migratoria migratorioides are often seen to march together in common bands in the field. In the present study, the intraspecific aggregation responses of nymphal and older stages of the two insects were compared with their interspecific responses. Unlike S. gregaria, L. m. migratorioides shows a lesser pattern of stage and sex differentiation in its aggregation pheromone biology. Thus, although fifth-instar nymphs did not respond significantly to the adult pheromone, adults responded significantly to the nymph pheromone. No cross- stage aggregative responses occur in S. gregaria. In the adults of S. gregaria, production of …

Evidence For Additional Pheromonal Components Mediating Oviposition Aggregation In Schistocerca Gregaria, Baldwyn Torto, Yousif O.H. Assad, Peter G.N. Njagi, Ahmed Hassanali

All Peer-Reviewed Publications

Oviposition responses of gregarious adult gravid females of the desert locust Schistocerca gregaria to sand previously used for oviposition by gregarious females (contaminated sand, with eggs and froth removed) and to sterilized sand (noncontaminated sand) were compared in bioassays. Gregarious females preferentially oviposited into contaminated sand. The number of egg pods laid by the females was found to correlate with the frequency of use of the contaminated sand for oviposition. Charcoal-trapped volatiles from the contaminated sand also elicited similar responses from gregarious females. Gas chromatography-electroantennographic detection (GC-EAD) analysis of the trapped volatiles revealed the presence of three electrophysiologically active compounds …
