Osteogenesis imperfecta(OI),also known as brittle bone disease,is characterized by low bone mass and bone fragil-ity,which varies in severity from asymptomatic to perina-tal lethality[1].Most patients with OI experience recur-rent bone fractures with or without short stature,facial dysmorphism,and skeletal *** accompany-ing extraskeletal manifestations include blue sclerae,joint laxity,dentinogenesis imperfecta,and hearing *** 85-90%of patients with OI have mutations in either COL1A1 or COL1A2,which elicit defects in typeⅠ***,an X-linked subtype of OI that is unre-lated to collagen was identified and was attributed to muta-tions in the plastin 3 gene(PLS3)[2].

In this paper, a novel biosensor was prepared by immobilizing glucose oxidase （GOx） on carbon nanotube-gold-titania nanocomposites （CNT/Au/TiO2） modified glassy carbon electrode （GCE）. SEM was initially used to investigate the surface morphology of CNT/Au/TiO2 nanocomposites modified GCE, indicating the formation of the nano-porous structure which could readily facilitate the attachment of GOx on the electrode surface. Cyclic voltammogram （CV） and electrochemical impedance spectrum （EIS） were further utilized to explore relevant electrochemical activity on CNT]Au/TiO2 nanocomposites modified GCE. The observations demonstrated that the immobilized GOx could efficiently execute its bioelectrocatalytic activity for the oxidation of glucose. The biosensor exhibited a wider linearity range from 0.1 mmol L-1 to 8 mmol L^-1 glucose with a detection limit of 0.077 mmol L^- 1.

It is well known that zinc ions play an indispensable role in the structure and function of a large number of biological process and relevant bio-macromolecules. When some cancers occurred, the relevant concentration of zinc ions considerably decreased. Since cancer cells have a completely different redox homeostasis from normal cells, in this contribution, we have explored the possibility of bio-imaging or labeling of cancer cells through the in situ biosynthesized zinc nanoclusters by cancerous cells. The results demonstrate that we can readily realize the in vivo fluorescent bio-imaging of cancer cells through the in situ biosynthesis of the biocompatible zinc nanoclusters from cancerous cells （i.e., Hela cervical carcinoma cell line and others） when target cells cultured with micromolar zinc gluconate solutions.

A preliminary study on a novel free base porphyrin dimer and a zinc prophyrin dimer by comparing their fluorescence properties with those of the corresponding monomers is presented. The fluorescence intensity of the free base dimer is five times higher than that of the monomer, but the fluorescence intensity of the zinc porphyrin dimer is nearly similar to that of the zinc porphyrin monomer. The emission spectra show that energy transfer occurs between the two units.

A field investigation was conducted at the Shenyang Experimental Station of Ecology, Chinese Academy of Sciences, in an aquic brown soil of Northeast China under three land use types (cropland, abandoned cropland, and woodland) in order to evaluate whether the vertical distribution and seasonal fluctuation for the number of total nematodes and trophic groups could reflect soil ecosystem differences and to determine the relationships between soil chemical properties and soil nematodes. The majority of soil nematodes were present in the 0-20 cm soil layers, and for these land use types plant parasites were the most abundant trophic group. In the abandoned cropland the numbers of plant parasites reached a peak on the August sampling date, whereas the cropland and woodland peaked on the October sampling date. Meanwhile, in all land use types the number of total nematodes, bacterivores, plant parasites, and omnivores-predators was negatively (P < 0.05, except for bacterivores in cropland, which was not significant) correlated with bulk density, and positively (P < 0.05, except for fungivores in abandoned cropland, which was not significant) correlated with total organic carbon and total nitrogen.
