Abstract
We have analysed the formation of streak artefacts in the reconstruction based on the filtered back projection algorithm in electron tomography (ET) and accordingly applied an adaptive interpolation technique to artefact reduction. In the adaptive interpolation to recover the missing information, the edge positions in a projection curve were tracked to reduce the interpolation error. A simulation was used to demonstrate the effectiveness of the artefact reduction. Furthermore, image reconstruction of integrated circuit specimens in the ET experiments with the ultra-high voltage electron microscope show that the strong streak artefacts can be reduced effectively by our artefact reduction technique.

Abstract
MicroRNAs (miRNAs) are non-coding single-stranded RNAs with about 21~23 nucleotides in length, which originate from encoding genes in nucleus. miRNAs play an inhibitory role in gene expression in a post-transcriptional level by partially complementary binding to the 3' unstranlated region (UTR) of target mRNAs. Large bodies of evidence have shown that miRNAs were involved in various diseases, such as cancer, infectious diseases, diabetes etc, and rising as critical modulators of pathological processes. Lately, some highlight articles revealed that the altered expression of miRNAs such as miR-1, miR-133, miR-21, miR-208 etc in hearts also contributed to cardiovascular diseases, such as heart ischemia, cardiac hypertrophy, and arrhythmias. Moreover, miRNAs were also identified to regulate heart development. These exciting findings not only improve our understanding of the molecular mechanisms of heart diseases, but also provide a new class of potential molecular targets. miRNAs, for the development of novel agents to treat heart diseases. Here, we summarized the recent discoveries about the role of miRNAs in cardiac physiological and pathological functions, and then discussed about their therapeutic potentials for heart diseases.

Abstract
Allergic asthma is associated with eosinophilic inflammation in the airways. Animal models commonly used to elucidate allergic inflammation mechanisms include BALB/c and C57BL/6 mice. Our aim was to evaluate lung eosinophilia and the corresponding Th1/Th2 balance in the two strains after allergen exposure. BALB/c and C57BL/6 mice were subjected to ovalbumin-induced allergic airway inflammation using BrdU to label newly produced cells. The numbers of new eosinophils were evaluated by differential cell count and immunocytochemistry (MBP+BrdU+). Proliferation rate of lung eosinophils was measured by analysis of CD45+CCR3+BrdU+ cells by FACS. Distribution of newly produced eosinophils in the lung and the Th1/Th2 (CD4+T-bet+/CD4+GATA-3+) balance was evaluated by immunohistochemistry. Allergen challenge with ovalbumin induced comparable eosinophilia in bone marrow (BM), blood and lung tissue in both strains of mice compared to phosphate-buffered saline controls, which was confirmed by immunocytochemistry. There was a small increase in the number of lung MBP+BrdU(-) eosinophils in C57BL/6 mice compared to BALB/c mice, which suggests a basal increase in this strain following sensitization. While there was no difference in eosinophilic proliferation in the lung, the distribution of the newly produced eosinophils differs between the two strains. BALB/c mice showed staining primarily around vessels and airways, whereas C57BL/6 mice showed a more even distribution in the lung tissue. No difference in the Th1/Th2 balance was observed between two strains. This study shows that there is a difference in the distribution of eosinophils in the lung between the C57BL/6 and BALB/c mice, but no difference in eosinophil production or Th1/Th2 balance.

Abstract
BACKGROUND Recent evidence has shown clinical phenotypic heterogeneity of inherited prion diseases, even between patients harbouring the same mutation in the PRNP gene. OBJECTIVE AND METHODS We collected clinical data from a Chinese family with autosomal dominant dementia and screened the PRNP gene on 28 living members. A stereotactic biopsy of the right frontal lobe of the proband was performed. RESULTS The family comprised four affected individuals within two successive generations. The age of onset was in 30 or 40 s, and the duration was about 2-3 years. Clinical features of the affected members included neuropsychiatric disturbances, progressive dementia and extrapyramidal symptoms. Immunostaining for prion protein showed fine granular deposits of PrP(sc) in the neuropil. The PRNP gene analysis demonstrated a heterozygous G114V mutation in 15 family members. The proband was diagnosed as familial Creutzfeldt-Jakob disease (fCJD). CONCLUSION This study strengthens the linkage of the G114V mutation to CJD. It supports the worldwide distribution of fCJD despite differences in genetic background.

Abstract
UNLABELLED A recent survey of bone mineral density (BMD) in China recruited 7,042 healthy Han Chinese aged 20 years and older. The mean BMDs were different in gender, age, and region; the proportions of men and women older than 50 years with a high risk of osteoporosis were estimated as 10.4% and 31.2%, respectively INTRODUCTION A survey of BMD was completed during 2002-2006 in China. By three-stage sampling, a total of 7,042 healthy Han Chinese aged 20 years and older were recruited in ten cities: 2,694 subjects from Beijing, Tianjin, Haerbin, Lanzhou, and Yantai of northern China and 4,348 from Shanghai, Changsha, Chengdu, Haikou, and Foshan of southern China. METHODS Two dual X-ray absorptiometry (DXA) systems (Hologic and Lunar) were used with parallel measurements of the European spine phantoms in each center. The mean BMDs in age groups older than 50 and the peak bone mineral density (pBMD) at femoral neck and that at greater trochanter were higher for men than women, and the pBMDs for northern China were higher than those for southern China, ranging from 1% to 4%. DISCUSSION AND CONCLUSION This work has provided two useful references for the first time: one is the estimation of the proportion and number of individuals older than 50 years with a high risk of osteoporosis, 10.4% and 12.5 million men, 31.2% and 37.2 million women, which is important for health care planning and marketing projections, and another is the conversion equations for cross-calibration among different types of DXA instruments frequently used in China.

Abstract
BACKGROUND Optimal long-term management of symptomatic gastro-oesophageal reflux disease (sGERD) patients has not been established. AIM To determine the clinical value of maintenance intermittent treatment with rabeprazole 20 mg vs. placebo in patients with sGERD. METHODS This multicentre, US study enrolled patients with sGERD (>or=3-month history of GERD symptoms and >or=4 days/week of heartburn during a 2-week placebo run-in) without oesophageal erosions. Patients with complete heartburn control after 4 weeks of open-label rabeprazole 20 mg daily treatment were randomized to 6-month, double-blind, maintenance intermittent treatment (7- to 14-day courses when heartburn recurred) with rabeprazole 20 mg or placebo. RESULTS The primary efficacy end point, mean percentage of heartburn-free days, was significantly greater with rabeprazole vs. placebo: 82.58% and 62.17% (ITT; P < 0.0001) [per protocol 86.74% rabeprazole vs. 74.93% placebo (P < 0.0254)]. Compared with placebo group, the rabeprazole group also experienced a significantly higher percentage of heartburn-free daytime (84.06% vs. 63.39%; P < 0.0001) and nighttime (95.41% vs. 90.25%; P = 0.0021) periods, had significantly fewer discontinuations because of insufficient heartburn control (6.3% vs. 36.3%; P < 0.0001) and took fewer antacid tablets daily (0.58 vs. 1.16; P = 0.0021). CONCLUSION Intermittent use of rabeprazole may be an effective maintenance treatment strategy for patients with sGERD and warrants further investigation. This trial was registered with http://clinicaltrials.gov under the number NCT00165841.

Abstract
Porous metal (Pd and Co) and semiconductor (ZnO) nanowires, porous metal (Pt and Ni) nanotubes, and unique multiple Pt nanowires are prepared from a novel nanoconfined surfactant templated electrodeposition approach. More specifically, the overall diameter of nanowires or nanotubes is defined by the pore channels of membranes. Surfactant assembled structure nanoconfined within the pores of membranes is used to generate the porosity and to control the texture of the nanowires or nanotubes. As compared to solid nanowires and nanotubes, the porous nanowires and nanotubes exhibit unique properties. For example, porous cobalt nanowires show higher coercivity.

Abstract
It is known that dentin sialophosphoprotein (DSPP) is processed into NH(2)- and COOH-terminal fragments, but its key cleavage site has not been identified, nor has its full-length form been discovered. The objectives of this study were to identify the key cleavage site during DSPP processing and to search for full-length DSPP in vivo. We generated a construct encoding DSPP, in which Asp(452), a cleavage site residue, was replaced by Ala(452). The pulp-odontoblast complex and dentin were extracted, chromatographically separated, and assessed by Stains-All staining, Western immunoblotting, and mass spectrometry. These studies showed that the substitution of Asp(452) by Ala(452) completely blocks the cleavage of mouse DSPP in the transfected cells, indicating that the NH(2)-terminal peptide bond of Asp(452) is essential for the initiation of DSPP proteolytic processing. The results of this study revealed the presence of full-length DSPP and its processed fragments in extracts from the pulp/odontoblast and dentin.

Abstract
Abstract
Objective: To evaluate whether use of oral contraceptives (OCs) or menopausal hormonal therapy (MHT) is associated with B-cell non-Hodgkin lymphoma (NHL).
Methods: Within the prospective California Teachers Study cohort, women under age 85 with no history of hematopoietic cancer were followed from 1995 through 2007 for diagnosis of B-cell NHL. Overall, 547 women of 116,779 women eligible for analysis of OC use and 402 of 54,758 postmenopausal women eligible for analysis of MHT use developed B-cell NHL. Relative risks (RR) and 95% confidence intervals (CI) were estimated by fitting multivariable Cox proportional hazards models.
Results: Women who used OCs had marginally lower risk of B-cell NHL than women who had never used OCs (RR = 0.86, 95% CI = 0.69-1.06). The reduced risk was most pronounced among women who started OCs before age 25, but did not decrease with increasing duration. No association with MHT was observed when MHT ever users were compared to the never users (RR = 1.05, 95% CI = 0.83-1.33); this result was consistent across formulations of MHT [unopposed estrogen therapy (ET), combined estrogen and progestin therapy (EPT)]. Among women who had never used MHT, women with a bilateral oophorectomy had three times greater risk than those with natural menopause (RR = 3.15, 95% CI = 1.62-6.13), whereas there was no association with bilateral oophorectomy among women who had used MHT. In stratified analyses according to hysterectomy and oophrectomy status, ET and EPT did not affect risk for women with natural menopause or those with hysterectomy who had at least part of an ovary remaining. Among women who had a bilateral oophorectomy, ET reduced risk of NHL (RR = 0.41, 95% CI = 0.21-0.82).
Conclusion: These data suggest that ET use decreases the risk of B-cell NHL among women with both ovaries removed, but not among women retaining at least part of an ovary. In other subgroups MHT does not influence risk. Additional study of associations of MHT and OCs with B-cell NHL are warranted.

Abstract
The UASB reactor was applied for biodegradation of organic compounds in coking wastewater. The influent pH ranged between 6.8 and 7.2, and stirring speed and temperature were controlled at 2 r/min and 30±1°C, respectively. The reactor was successfully started up in 133 days. When the influent COD was 2,600 mg/L (VLR was 2.6 kg/m(3) d), the removal rate of COD was about 54% and the effluent VFA was below 400 mg/L. GC/MS analysis indicated that the coking wastewater mainly contained aniline, phenol, o-phenol, p-cresol, benzoic acid, indole, quinoline etc. Twenty four kinds of organic compounds were detected in the influent, and 20 kinds of organic compounds were completely removed in the UASB reactor. The biodegradation of organic compounds followed Grau second-order kinetics. It was proved to be an effective and feasible method for coking wastewater anaerobic treatment.

Abstract
A significant increase in nonhuman primate models of human diseases will be expected in the near future since the successes in production of genetically engineered rhesus monkey models of human diseases. Sperm banking can provide an effective way to preserve valuable genetic resources. Our objective was to (1) develop a protocol using directional freezing technique (DFT) for rhesus monkey spermatozoa cryopreservation, which allows precise control of the velocity and the morphology of the ice-front propagation by transferring the tubes loaded with 2 mL sperm samples at a controllable velocity through two separate chambers with controllable temperature settings, and (2) achieve survival rate that was higher than that achieved with conventional freezing technique (CFT), by which sperm samples were cryopreserved in 0.25 mL straws with liquid nitrogen vapor in a styrofoam box. Sperm motility, acrosomal integrity, and in vitro fertilization (IVF) assay were used to assess the function of frozen-thawed spermatozoa. Data were analyzed by ANOVA and Fisher protected LSD test. Experiment 1 was aimed at optimizing the cooling rate using DFT. Tubes were frozen using the multi-thermal gradient freezing device (MTG 516, Harmony CryoCareTM, IMT Ltd.) at fast (16°C/min), medium (12°C/min), and slow (7°C/min) cooling rates, which corresponded to the transferring velocities (2.5, 1.5, and 0.5 mm s-1, respectively). The results showed that spermatozoa frozen at fast and medium cooling rates showed significantly higher frozen-thawed motility than those frozen at slow cooling rate (61% and 59% v. 50%, P < 0.05). However, no difference was observed on sperm acrosomal integrity among the experimental groups (84, 80, and 78%, respectively, P > 0.05). The purposes of Experiment 2 were determined to examine if using DFT at the optimized cooling rate (12°C/min) can improve the cryo-survival of rhesus monkey spermatozoa compared with CFT. Our results showed that spermatozoa cryopreserved by using DFT achieved significantly higher frozen-thawed sperm motility that those cryopreserved by using CFT (64 v. 54%, P < 0.05). However, no difference was observed on acrosomal integrity between spermatozoa cryopreserved by DFT and CFT (84 and 83%, respectively; P > 0.05). The function of spermatozoa cryopreserved by using DFT was further evaluated by IVF. Females were treated with rhFSH twice-daily for 8 days after the onset of menses and following a treatment of hCG injection on Day 9. Cumulus-oocyte complexes were collected by laparoscopic follicular aspiration 32 h later. Of the inseminated oocytes, 79% were fertilized and 90 and 53% of the resulting zygotes developed into 2-cell and blastocysts, respectively. The fertilization rate was lower and the blastocyst rate was slightly higher than our previous report when fresh spermatozoa were used for IVF (94 and 52%, respectively). Our results indicate that spermatozoa of rhesus monkeys can be effectively cryopreserved using DFT in large volume. This finding provided a new and effective way for genetics preservation purposes in this important species.

Abstract
Parity-odd domains, corresponding to nontrivial topological solutions of the QCD vacuum, might be created during relativistic heavy-ion collisions. These domains are predicted to lead to charge separation of quarks along the system's orbital momentum axis. We investigate a three-particle azimuthal correlator which is a P even observable, but directly sensitive to the charge separation effect. We report measurements of charged hadrons near center-of-mass rapidity with this observable in Au + Au and Cu + Cu collisions at square root of s(NN) = 200 GeV using the STAR detector. A signal consistent with several expectations from the theory is detected. We discuss possible contributions from other effects that are not related to parity violation.
