Abstract
By combining two different materials, metal-organic frameworks (MOF) and β-cyclodextrins (β-CD), a signal amplification electrochemical luminescence (ECL) immunosensor was constructed to realize the sensitive detection of AFP. The indium-based metal-organic framework (In-MOF) was used as the carrier of Ru(bpy)32+, and Ru(bpy)32+ was immobilized by In-MOF through suitable pore size and electrostatic interaction. At the same time, using host-guest recognition, β-CD enriched TPA into the hydrophobic cavity for accelerating the electronic excitation of TPA, then, achieving the purpose of signal amplification. The signal amplification immunosensor structure is constructed among the primary antibody Ab1 connected to the Ru(bpy)32+@In-MOF modified electrode, AFP, BSA and the secondary antibody (Ab2) loaded with TPA-β-CD. The immunosensor has a good linearity in the range of 10-5 ng/mL-50 ng/mL, and the low limit of detection (LOD) is 1.1 × 10-6 ng/mL. In addition, the electrochemiluminescence immunosensor that we designed has strong stability, good selectivity and repeatability, which provides a choice for the analysis of AFP.

Abstract
Alpha-fetoprotein (AFP) is the best diagnostic marker for hepatocellular carcinoma (HCC) and plays an important role in the general surveillance of the population. Therefore, the establishment of an ultra-sensitive AFP assay is essential for the early screening and clinical diagnosis of HCC. In this work, we designed a signal-off biosensor for ultra-sensitive detection of AFP based on an electrochemiluminescent resonance energy transfer (ECL-RET) strategy using luminol intercalated layered bimetallic hydroxide (Luminol-LDH) as an ECL donor and Pt nanoparticles-grown on copper sulfide nanospheres (CuS@Pt) as ECL acceptor. The (Au NPs/Luminol-LDH)n multilayer nanomembrane synthesized by our intercalation and layer-by-layer electrostatic assembly process not only effectively immobilizes luminol but also significantly enhances the ECL signal. The CuS@Pt composite has well visible light absorption ability and can burst the light emitted from luminol by ECL-RET. The biosensor showed good linearity in the range from 10-5 ng mL-1 to 100 ng mL-1 and a minimum detection limit of 2.6 fg mL-1. Therefore, the biosensor provides a novel and efficient strategy for the detection of AFP, which is important for the early screening and clinical diagnosis of HCC.

Abstract
Herein, MWCNT-graft-polyimides (MWCNT-g-PIs) were prepared by the in situ grafting method. Strengthening the interfacial interaction between MWCNTs and polyimide chains decreased their interfacial thermal resistance (RC). In contrast to the RC of 10% MWCNT/PIs, the RC of 10% MWCNT-g-PI decreased by 16.7%. Hence, MWCNT-g-PIs possessed higher thermal conductivity than MWCNT/polyimides (MWCNT/PIs). Meanwhile, the Tg values of all the samples (MWCNT/PIs and MWCNT-g-PIs) were greater than 399 °C (by DMA). Compared with MWCNT/PIs, 5% and 10% MWCNT-g-PIs showed enhancement in thermal stability in air. The storage modulus retentions were greater than 63% at 200 °C and 45% at 300 °C. Also, 5% and 10% MWCNT-g-PIs maintained the high tensile strength of pure PI, and the tensile modulus increased up to 2.59 GPa on increasing the loading amount of MWCNTs. This study sheds light on improving the thermal conductivity of polyimides effectively at relatively low loadings. In situ synthesis of MWCNT-graft-polyimides enhanced thermal conductivity at a relatively low loading.![]()

Abstract
In this study, we built a novel handheld array photoacoustic probe by integrating multiple optical components with a transrectal ultrasound (TRUS) transducer array. The optical components deliver laser energy and TRUS is used for photoacoustic signal detection. Compared to the previously reported probe, the new photoacoustic probe utilizes an optimized light illumination scheme to enhance the utilization-efficiency of the laser energy, thus improving the imaging sensitivity of the probe. In addition, the new probe is compact and easy to handle for clinicians. We validated the use of this photoacoustic probe for prostate cancer imaging through both phantom studies and in vivo canine model study, which mimics the prostate cancer conditions. The results showed that the probe is suitable for clinical use and can be used in the clinics for several potential clinical applications, including early diagnosis of prostate cancer, targeted image-guided biopsy, and image-guided intra-operative procedure.

Abstract
Self-biting disease occurs in most farmed fur animals in the world. The mechanism and rapid detection method of this disease has not been reported. We applied bulked sergeant analysis (BSA) in combination with RAPD method to analyze a molecular genetic marker linked with self-biting trait in mink group. The molecular marker was converted into SCAR and loop-mediated isothermal amplification (LAMP) marker for rapid detection of this disease. A single RAPD marker A10 amplified a specific band of 1000bp in self-biting minks. The sequences of the bands exhibited 73% similarity to the Canis Brucella. SCAR and LAMP marker were designed for the specific fragment of RAPD marker A10 and validated in 30 self-biting minks and 30 healthy minks. c2 test showed difference (p0.05) with SCAR and significant difference (p0.01) with LAMP in the detection rate between the two groups, but LAMP method was more accurate than SCAR method. This indicated that LAMP can be used as a positive marker to detect self-biting disease in minks.

Abstract
The optimal photoacoustic probe design is the key to obtain highest imaging sensitivity in photoacoustic computed tomography. Two commonly used probe design types are dark- and bright-field designs. We proposed a design for photoacoustic probe called quasibright-field illumination and compared the performance of all three kinds of probes theoretically and experimentally. Our conclusion is that the proposed quasibright-field illumination photoacoustic probe is superior compared to the existing probe designs as demonstrated. However, each type of illumination should still have its own advantages under certain circumstances. The dark-field illumination is capable of minimizing surface interference signals and reducing their contributions to the background of deeper signals. Hence, it should perform better when imaging samples with high optical absorbance at the surface layer. The bright field may perform better under circumstance when phase distortion is less. We also designed and fabricated three kinds of probes using a single multimode optical fiber for laser energy delivery instead of fiber bundle. Single fiber probes are low cost, transmit laser energy efficiently, and are compact for easy handling. Thus, our study not only provides a method for probe design but also a guidance for cost-effective transducer array-based photoacoustic probe design and manufacturing in the future.

Abstract
Two abietane and one labdane type diterpenoids were isolated from the methanol extracts of Torreya nucifera pulp and investigated for their ability to inhibit the growth of human cancer cells. Among the three compounds, the labdane compound kayadiol was found to have the most effective inhibitory effect against a wide variety of human cancer cells. Using the MTT assay, kayadiol was determined to have an IC50 (50% inhibition concentration) of 30 µM in HeLa cells, and also to exhibit anti-proliferative effects towards six other human cancer cell lines, with IC50 values of 30-50 µM. Kayadiol treatment of HeLa cells resulted in a dose-dependent generation of apoptotic events, including DNA laddering (≤100 µM). Moreover, kayadiol-treated HeLa cells showed activation of caspases-3 and -9, as well as an increase in the depolarization of mitochondrial membrane potential and the Bax/Bcl-2 ratio. These results indicate that a mitochondria-related apoptotic pathway is involved in the kayadiol-induced death of HeLa cells. Kayadiol is therefore a promising novel anti-proliferative agent and merits further investigation.

Abstract
Mutation at the fasciated locus was a key step in the production of extreme fruit size during tomato domestication. To shed light on the nature of these changes, near-isogenic lines were used for a comparative developmental study of fasciated and wild-type tomato plants. The fasciated gene directly affects floral meristem size and is expressed before the earliest stages of flower organogenesis. As a result, mature fruit of fasciated mutants have more carpels (locules) and greater fruit diameter and mass. The discovery that fasciated affects floral meristem size led to a search for candidate genes from Arabidopsis known to be involved in floral meristem development. Putative homologs were identified in a large tomato EST database, verified through phylogenetic analyses, and mapped in tomato; none mapped to the fasciated locus; however, putative homologs of WUS and WIG mapped to the locule number locus on chromosome 2, the second major transition to large tomato fruit, with WUS showing the highest association. In other cases, minor QTLs for floral organ number (lcn2.2) and (stn11.2) co-localized with a CLV1 paralog and with the syntenic region containing the CLV3 gene in Arabidopsis, respectively.Key words: fasciated, floral meristem, locule number, Arabidopsis, fruit.

Abstract
OBJECTIVE To detect the location of inducible nitric oxide synthetase (iNOS) protein and mRNA in lung during endotoxemia in rabbits. METHODS Northern blotting was performed before, 1 hour and 5 hours after the intravenous administration of lipopolysaccharide (LPS) in rabbits. Immunohistochemical analysis (IA), in situ hybridization and in situ reverse transcription-polymerase chain reaction (in situ RT-PCR) were also performed in lung sections. RESULTS iNOS mRNA expression was found using Northern blotting in lung 5 hours after LPS injection, while it was not found in control. The positive stain was found only in macrophages in lung 5 hours after LPS injection by standard hybridization and IA; while by in situ RT-PCR, the amplification products were found in macrophages, airway epithelial cells, vascular endothelial cells, smooth muscle cells and leukocytes, in addition to macrophages distributed abundantly throughout the lung. The signal was absent in control or samples. CONCLUSIONS Using an in situ RT-PCR technique, iNOS expression was not only observed in macrophages but also in many other kinds of cells in lung during endotoxemia in rabbits. This suggests that in situ RT-PCR is much more sensitive than in situ hybridization, and can be used to examine genes with low expression.

Abstract
Determining the depth to which continental lithosphere can be subducted into the mantle at convergent plate boundaries is of importance for understanding the long-term growth of supercontinents as well as the dynamic processes that shape such margins. Recent discoveries of coesite and diamond in regional ultrahigh-pressure (UHP) metamorphic rocks has demonstrated that continental material can be subducted to depths of at least 120 km (ref. 1), and subduction to depths of 150-300 km has been inferred from garnet peridotites in orogenic UHP belts based on several indirect observations. But continental subduction to such depths is difficult to trace directly in natural UHP metamorphic crustal rocks by conventional mineralogical and petrological methods because of extensive late-stage recrystallization and the lack of a suitable pressure indicator. It has been predicted from experimental work, however, that solid-state dissolution of pyroxene should occur in garnet at depths greater than 150 km (refs 6-8). Here we report the observation of high concentrations of clinopyroxene, rutile and apatite exsolutions in garnet within eclogites from Yangkou in the Sulu UHP metamorphic belt, China. We interpret these data as resulting from the high-pressure formation of pyroxene solid solutions in subducted continental material. Appropriate conditions for the Na2O concentrations and octahedral silicon observed in these samples are met at depths greater than 200 km.

Abstract
Domestication of many plants has correlated with dramatic increases in fruit size. In tomato, one quantitative trait locus (QTL), fw2.2, was responsible for a large step in this process. When transformed into large-fruited cultivars, a cosmid derived from the fw2.2 region of a small-fruited wild species reduced fruit size by the predicted amount and had the gene action expected for fw2.2. The cause of the QTL effect is a single gene, ORFX, that is expressed early in floral development, controls carpel cell number, and has a sequence suggesting structural similarity to the human oncogene c-H-ras p21. Alterations in fruit size, imparted by fw2.2 alleles, are most likely due to changes in regulation rather than in the sequence and structure of the encoded protein.

Abstract
The plant MADS-box gene family plays a key role in plant development, especially in flower development. We designed degenerate primer according to the MADS-box conserved region and isolated two cDNA from rice, FDRMADS6 and FDRMADS7, which are homologous to AP1. RT-PCR expression analyses by using total RNA isolated from root, shoot and flower showed that the FDRMADS6 transcript was detectable only in flower while FDRMADS7 was expressed in all three tissues. In situ hybridization experiments indicated that at the early stage of rice flower development, the transcripts of FDRMADS6 and FDRMADS7 were detected in the spikelet apical meristem, which were same as AP1. At the late stage, when flower organ primordia started differentiating, the expression of FDRMADS6 appeared to be specifically localized in developing stamens and the pistil primordia, while the transcripts of FDRMADS7 were detectable abundantly throughout the organ primordia. Our results suggest the two MADS-box genes may be members of the AP1 family, but may have different functions.

Abstract
OBJECTIVE To study the polymorphism at D1S8 locus and to provide basic information for the construction of DNA fingerprint database and the application in forensic medicine. METHODS Minisatellite variant repeat-polymerase chain reaction (MVR-PCR) and polyacrylamide gradient gel electrophoresis followed by silver staining were used to detect the variant repeat sequences at D1S8 locus of 240 unrelated individuals in Hebei Han population, and digital codes were obtained. RESULTS Each individual obtained about 30 digital codes, in which none of two unrelated individuals had the same code. The probability of identity of 30 digital codes was 3.55x10(-11). The percentages of three repeat units, a-type, t-type and o-type were 54.77%, 42.54% and 2.69% respectively. The heterozygosity (H) was 0.9837. The excluding probability of paternity(EPP) and polymorphism information content(PIC) were 0.9669 and 0.9833 respectively. CONCLUSION Because of its high polymorphic nature, D1S8 locus is a valuable marker for forensic identification and paternity testing.

Abstract
OBJECTIVE To explore the roles of peroxynitrite (ONOO(-)) in acute lung injury induced by lipopolysaccharides (LPS). METHODS Nitrotyrosine (NT), a specific marker of in vivo ONOO(-) production, was detected with immunohistochemical technique in rat lung during endotoxin shock (LPS 5 mg/kg iv). Lung coefficient (LC), lung wet/dry weight ratio (W/D), the contents of water and Evans blue (EB) in lungs were measured after intratracheal insufflation of ONOO(-) with different doses. Monastral blue (MB)-labelled blood vessels and pathological changes in lungs were examined under a light microscope. RESULTS After 2 or 6 hours of LPS intravenous administration, severe lung injury and positive signals of NT occurred with the latter located in the pulmonary macrophages, endothelia, subendothelial and muscular layers of the pulmonary artery. Administration of exogenous ONOO(-) caused dose-dependent increase in LC, W/D, ater and EB contents and in the number of MB-labelled blood vessels in rat lungs, together with significant pathological alterations such as diffuse alveolar collapse, capillary congestion in the septa and focal hemorrhage. CONCLUSION In the early stage of endotoxin shock, severe lung injury and ONOO(-) production simultaneously exist, and exogenous ONOO(-) could induce significant dysfunction of microvascular endothelial barrier and lung injury, indicating that ONOO(-) generation in vivo may be involved in the pathogenesis of acute lung injury.

Abstract
The Chinese Han population was studied for the D1S80 (pMCT118) locus. Bloodstain samples of 216 unrelated individuals were tested through Chelex extraction and the polymerase chain reaction (PCR). After amplification, the genotypes were separated by polyacrylamide gel (PAG) electrophoresis and stained with ethidium bromide. A total of 70 genotypes and 25 alleles were distinguished. Alleles 18, 24 and 30 were the most common alleles in Chinese population. The distribution of the observed genotypes conformed to the Hardy-Weinberg equilibrium for the D1S80 (pMCT118) system. The chance of exclusion, the discriminating power (DP), and the heterozygosity for this system were 0.71, 0.90, and 0.85, respectively, in Chinese population.

Abstract
From September 1985 to December 1992, 160 cases of reconstruction of the esophagus with the whole stomach through the esophageal bed after resection of the upper esophageal carcinoma were performed with neither operative mortality nor intrathoracic complications. The leakage rate of the cervical anastomosis with Gambee's single layer method was 1.2%. The main steps of the operative procedure consisted of: (1) making a right thoracotomy for dissecting and removing the entire thoracic esophagus; (2) laparotomy for mobilizing the whole stomach, constricting it to tube shape and doing a pyloroplasty; and (3) pulling up the mobilized tube-like stomach through the posterior mediastinal space (i.e. the esophageal bed) out of the left neck incision and then the esophagogastrostomy with Gambee's single layer anastomosis was performed.
