  ABSTRACT: To study the differences of protein expression levels in the brain cortex of human fetus and adult with proteomics technique, and provide preliminary data on the change of proteins during brain development. Proteins extracted from human temporal lobes in fetal (3 month and 5 month respectively) and adult (30 years old) brain were separated by two-dimensional gel electrophoresis (2DE). The proteins were then stained with colloidal Coomassie blue to produce a high-resolution map of the proteiome. The differential protein spots were analyzed by PDQuest 7.0 software and 8 spots, which were gradually reduced or gradually increased in brain development process and the protein spots of difference over two-fold in the brain, were identified by matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF/TOF). (1) On average, 642, 511 and 527 protein spots could be obtained in the temporal lobes of adult, 3 month and 5 month fetus. The matching rate of images was 87%. The basic proteins in adult brain were obviously much more than that in the fetus; (2) There were 172, 171 and 152 singular protein spots in temporal lobes of adult, 3 month and 5 month fetus respectively.(3) Compared with adult, there were 131 and 115 different protein spots in the 3 month and 5 month fetus respectively. There were 60 and 40 protein spots with more than 2 fold difference, among which 24 and 17 were down-regulated, and 36 and 23 were up-regulated respectively. (4) There was different expression in proteins such as serum albumin, triosephosphate isomerase, etc. in the 3 groups. Fatty acid binding protein 7 and unnamed proteins were only highly expressed in the 3 month brain; ribulose-1, 5-bisphosphate carboxylase/oxygenase large subunit and transducin beta-1 subunit were up-regulated in adult brain. Serum albumin decreases gradually with brain development. However, ATP synthase, mitochondrial F0 complex, and triosephosphate isomerase increase gradually with brain development. The proteins of human brain cortex were obviously changed from embryonic stage to adult. The differentially displayed proteins may provide further insight into the understanding of development of human brain.

  ABSTRACT: A new large-signal model and modeling method are presented. The pulsed I-V testing data is adopted to suppress the effects of traps and self-heating. The model has the enhanced simulation accuracy and convergence property. The improved parameter extraction technique has the features of efficiency and accuracy. The novel model has been verified in terms of I-V, C-V and power performance for different PHEMTs, HFETs and MESFETs as well as circuits.
