Item F H C Crick (1916 - 2004).(2004-12-31) Siddiqi, ObaidItem Odour avoidance learning in the larva of Drosophila melanogaster.(2009-10) Khurana, Sukant; Abubaker, Mohammed Bin; Siddiqi, ObaidDrosophila larvae can be trained to avoid odours associated with electric shock. We describe here, an improved method of aversive conditioning and a procedure for decomposing learning retention curve that enables us to do a quantitative analysis of memory phases, short term (STM), middle term (MTM) and long term (LTM) as a function of training cycles. The same method of analysis when applied to learning mutants dunce, amnesiac, rutabaga and radish reveals memory defi cits characteristic of the mutant strains.Item Proteins of the brain and body wall in larvae of Drosophila melanogaster.(1980-06) Donde, Sheela U; Siddiqi, ObaidProteins of the brain and body wall cells of third instar larvae of Drosophila melanogaster have been examined by two-dimensional gel electrophoresis. Out of over 600 [ 35 S ]-labelled peptide spots seen in brain or body wall extracts, 517 were common to both; 61 spots were unique to brain and 66 unique to muscle. Glycoproteins were identified by soaking the gels in radioactive iodinated Concanavalin-A. Forty four Con-Α binding glycoproteins were identifiable in the brain and 41 in the muscle extracts. Out of these, 8 glycoproteins of the brain and 8 of muscles appear to be tissue-specific.
