Conotoxins are short peptide-toxins with specific targets and large diversity. They are usetul in analgesia, neuroprotection, detection of some kinds of deseases, and receptor and ion channel study. in order to explore the conotoxin resourses of Chinese oceans, rapid amplification of 3’ cDNA ends (RACE) method was utilized to systemically analyze the O-superfamily conotoxin content of Conus striatus inhabited near Chinese Hainan Island. Six new O-superfamily conopeptides were identified, one of which is highly homologous to MVIlA, an N-type calcium channel antagonist.

A stable Pd(II) compound Pd(AETYF)Cl2CH2Cl2 (AETYF = 4?5?diaza-9? (4,5-bis(ethylthio)-1,3-dithiole-2-ylidene)-fluorene) has been synthesized and its crystal structure was determined by X-ray crystallography. The crystal is of monoclinic, space group P21/c with a = 15.249(6), b = 8.619(3), c = 19.078(7) ? b = 106.932(8), C19H18Cl4N2PdS4, Mr = 650.79, V = 2398.6(16) 3, Z = 4, Dc = 1.802 g/cm3, F(000) = 1296, m = 1.579 mm-1, Npar = 268, the final R = 0.0538 and wR = 0.1282 for 5068 observed reflections with I > 2s(I). The crystal structure determi- nation shows that the atoms of the molecule, except two ethyl-groups, are conjugated in a quasi- plane and these molecules are further stacked or contacted via plane to plane or edge to edge p-p interactions, forming parallel molecular chains along the b axis.

A passively Q-switched mode-locked Nd:GdYVO4 laser is successfully demonstrated by using a piece of GaAs crystal grown at low temperature as the passively saturated absorber and the output coupler. Fundamental properties of the Nd: GdYVO4 laser are investigated. The maximum average output power of 3.5 W is obtained by using plainsphere when the incident pumping power is 10 W,which corresponds to an optical-optical coversion efficiency of 35%. The threshold power for the Q-switching mode-locked is 1.2 W. The maximum average output power of 1.72 W is obtained by using GaAs when the incident pumping power is 10 W,mode-locked pulse train with a repetition rate of ～113 MHz is achieved. At the incident laser pumping power of 7 W,the modulation depth is 100%.
