Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。

Secondly, femtosecond time-resolved studies using fluorescence depletion spectroscopy were performed on Rhodamine 700 and Oxazine 750 in solutions to study the ultrafast dynamics, such as vibrational relaxation and the energy transfer from the solute to solvent. The orientational relaxation process of these dye molecules have been study in solution by the polariton resolved FS TR SEP FD.

Our results revealed that the CH/N substitution preserves the"paddle wheel"molecular shape, a key factor in the tunnel formation on which is based the use of TPP and TPP-like molecules for OZ use.

研究结果显示CH/N取代保持了作为有机分子筛形成孔道的关键因素的"桨轮"分子形状。

As a result, both the detection limit of the sensor decreased by 2～3 magnitudes and the signal magnitude increased about ten times than that of fly labellar single hairs. The sensitivity to many stimulants from simple molecules such as NaCl, KCl, sucrose, glycine, proline, glutamic acid and aspatic acid to macromolecule such as bovine surem albumin was lower than 10〓mol L〓. For this reason, the maxillary palp of cockroach is reveled as an important candidate for construction of a new type of intact-receptor biosensors.

这种协同作用导致下颚须感觉区对有些刺激物如NaCl，KCl，蔗糖，甘氨酸，脯氨酸，谷氨酸，天冬氨酸，牛血清白蛋白的响应阈值比一般单根感觉毛至少低2-3个数量级，达10〓molL〓以下；信号幅度提高约十倍，是一种新型的适合用作传感器的敏感材料。

Then they used the pattern formed by the beams as they bounced off the crystals to create computer-generated, 3-D images of the patterns of twisting and folding amino acid chains that make up the different types of pantothenate kinase and their interactions with the other molecules.
