Abstract
Abstract
Recently, with the development and application of full-scope level 2 probabilistic safety assessment (PSA) method around the world, severe accident phenomena during shutdown and low power conditions have aroused extensive attention in nuclear industry. And the shutdown severe accident management guideline (SSAMG) is claimed to be developed, and the verification of the traditional and alternative entry conditions is the first consideration in this procedure. Thus in this paper, the feasibility of the hot leg pipe temperature and the modified jakob number are analyzed based on a SBO sequence firstly. Subsequently, verification work is conducted under a SBO sequence with pressurizer manhole open and a SBO sequence along with SBLOCA. The results proved the excellent effectiveness of the two parameters to be used as alternative SSAMG entry conditions. Also, a relational figure is constructed based on the results of diverse sequences with various primary system pressure to provide visualized guidance for operators. What's more, the value of modified jakob number which indicates the SSAMG entry is thought to be in the range of 0.5–1.

Abstract
Previous studies have suggested that oral zinc supplementation can help reduce the duration of the common cold; however, the use of intranasal (IN) zinc is strongly associated with anosmia, or the loss of the sense of smell, in humans. Prior studies from this lab showed that upregulation of metallothioneins (MT) is a rapid and robust response to zinc gluconate (ZG). Therefore, we assessed the role of MT in the recovery of nasal epithelial damage resulting from IN zinc administration. The main studies in this investigation used a high dose of ZG (170mM) to ensure ablation of the olfactory mucosa, so that the progression of histological and functional recovery could be assessed. In vivo studies using wild-type, MT1/2 knockout mice (MT KO), and heterozygotes administered ZG by IN instillation showed profound loss of the olfactory mucosa in the nasal cavity. Recovery was monitored, and a lower percentage of the MT KO mice were able to smell 28 d after treatment; however, no significant difference was observed in the rate of cell proliferation in the basal layer of the olfactory epithelium between MT KO and wild-type mice. A lower concentration of ZG (33mM), equivalent to that found in homeopathic IN ZG preparations, also caused olfactory epithelial toxicity in mice. These studies suggest that the use of zinc in drug formulations intended for IN administration in humans must be carefully evaluated for their potential to cause olfactory functional deficits.

Abstract
Colitis induced by 2,4,6-Trinitrobenzenesulfonic acid (TNBS) has been used as a model for Crohn’s disease (CD) of inflammatory bowel disease (IBD). Lipocalin-2 (Lcn-2) is an emerging and clinically relevant biomarker of IBD. We investigated the performance of serum and fecal Lcn-2 in the TNBS model of colitis. Female, 7-week-old, BALB/c mice were administered intrarectally phosphate-buffered saline/water or 30% ethanol (vehicle control groups) for 5 days or TNBS for 5 days followed by a 28-day recovery phase. Serum and fecal levels of Lcn-2 were quantified, and effects on body weight, clinical scores, colon weight and length, gross pathology, and histopathology were investigated. Increased serum Lcn-2 levels correlated only with marked to severe inflammation. A clear differentiation in Lcn-2 fecal levels between TNBS-treated and vehicle-treated control mice was most noticeable on days 2 and 3. There was a strong correlation between body weight change, histopathologic scores of inflammation, and/or fecal Lcn-2 levels on days 2 and 5. Both serum and fecal Lcn-2 levels declined over time as the colonic mucosa recovered. Fecal Lcn-2 was found to be a more sensitive biomarker (vs. serum Lcn-2) and was able to discriminate mild, moderate, and severe colonic inflammation.

Abstract
Zinc is both an essential and potentially toxic metal. It is widely believed that oral zinc supplementation can reduce the effects of the common cold; however, there is strong clinical evidence that intranasal (IN) zinc gluconate (ZG) gel treatment for this purpose causes anosmia, or the loss of the sense of smell, in humans. Using the rat olfactory neuron cell line, Odora, we investigated the molecular mechanism by which zinc exposure exerts its toxic effects on olfactory neurons. Following treatment of Odora cells with 100 and 200μM ZG for 0-24h, RNA-seq and in silico analyses revealed up-regulation of pathways associated with zinc metal response, oxidative stress, and ATP production. We observed that Odora cells recovered from zinc-induced oxidative stress, but ATP depletion persisted with longer exposure to ZG. ZG exposure increased levels of NLRP3 and IL-1β protein levels in a time-dependent manner, suggesting that zinc exposure may cause an inflammasome-mediated cell death, pyroptosis, in olfactory neurons.

Abstract
AIMS State-of-the-art bioaerosol samplers have poor collection efficiencies for ultrafine virus aerosols. This work evaluated the performance of a novel growth tube collector (GTC), which utilizes laminar-flow water-based condensation to facilitate particle growth, for the collection of airborne MS2 viruses. METHODS AND RESULTS Fine aerosols (<500 nm) containing MS2 coliphage were generated from a Collison nebulizer, conditioned by a dilution dryer and collected by a GTC and a BioSampler. The GTC effectively condensed water vapour onto the virus particles, creating droplets 2-5 μm in diameter, which facilitated collection. Comparison of particle counts upstream and downstream revealed that the GTC collected >93% of the inlet virus particles, whereas the BioSampler's efficiency was about 10%. Viable counts of the GTC-collected viruses were also one order of magnitude higher than those of the BioSampler (P = 0·003). CONCLUSION The efficiency of the GTC for the viable collection of MS2 viruses exceeds that of industry standard instrument, the BioSampler, by a factor of 10-100. SIGNIFICANCE AND IMPACT OF THE STUDY This study reveals that the GTC is an effective collector of viable MS2 aerosols, and concludes the instrument will be an effective tool for studying viable virus aerosols and the inhalation risks posed by airborne viruses.

Abstract
Use of silver nanoparticles (AgNPs) for their antimicrobial properties is widespread. Much of the previous work on the toxicity of AgNPs has been conducted in vitro or following oral or intravenous administration in vivo. Intranasal (IN) instillation of AgNPs mimics inhalation exposure and allows further exploration of the toxicity of these particles via respiratory tract exposure. The present study involved 1) single-dose exposures to assess tissue distribution and toxicity and 2) repeated exposures to assess behavioral effects of IN AgNP exposure (nominally uncoated 25 nm AgNP). AgNP deposition was localized in the liver, gut-associated lymphoid tissue, and brain. Decrease cellularity in spleen follicles was observed in treated mice, along with changes in cell number and populations in the spleen. The splenic GSH:GSSG ratio was also reduced following AgNP exposure. Expression of the oxidative stress-responsive gene Hmox1 was elevated in the hippocampus, but not cortex of treated mice, as was the level of HMOX1 protein. Mice receiving 7 days of IN exposure to 50 mg/kg AgNPs exhibited similar learning- and memory-related behaviors to control mice, except that treated mice spent significantly less time in the target quadrant of the Morris Water Maze during the acquisition phase probe trial. These findings indicate systemic distribution and toxicity following IN administration of AgNPs.

Abstract
Zinc (Zn) has long been touted as a panacea for common cold. Recently, there has been some controversy over whether an intranasal (IN) zinc gluconate gel, purported to fight colds, causes anosmia, or loss of the sense of smell, in humans. Previous evidence has shown that IN zinc sulfate (ZnSO4) solutions can cause anosmia in humans as well as significant damage to the olfactory epithelium in rodents. Using an in vitro olfactory neuron model (the rat Odora cell line), we tested the hypothesis that Zn toxicity was caused by inhibition of the hydrogen voltage-gated channel 1(HVCN1), leading to acidosis and apoptotic cell death. Following studies to characterize the toxicity of zinc gluconate and ZnSO4, Odora cells were grown on coverslips and loaded with 2',7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein acetoxymethyl ester to measure intracellular pH in the presence and absence of Zn salts. While we found that HVCN1 is not functional in Odora cells, we found that olfactory neurons in vitro maintain their intracellular pH through a sodium/proton exchanger, specifically the sodium proton antiporter 1. ZnSO4, at nontoxic levels, had no impact on intracellular pH after acute exposure or after 24 h of incubation with the cells. In conclusion, Zn toxicity is not mediated through an acidification of intracellular pH in olfactory neurons in vitro.

Abstract
Abstract
Background: Numeration of CTCs from MBC pts is predictive of outcome. Quantitative changes in CTC-s are currently tested for their potential to monitor therapy (Rx). Biomarker characterization of CTCs may be a useful adjunctive guide for Rx selection. Method: At the COHCC between 5/1/2008 and 4/31/09, consecutively treated pts with newly diagnosed/or progressing MBC were accrued. Blood samples (10-40 ml) were procured prior to or during systemic Rx, and were sent to PARC for analysis. A novel high-speed scanning instrument located CTCs from cytokeratin (CK) labeling enabling high resolution images to be selectively acquired using digital microscopy. From these images, CTCs were identified by CK, DAPI (nuclear marker) and CD45, and protein expression levels were determined for HER2, ER, ERCC1 and EGFR. Cell lines with expression of each marker were used for normalization of the cell intensities, and a scoring system was used to account for relative number and expression levels of markers on the CTCs. Results: Of 21pts tested 81% were found to have detectable CTCs. CTCs were further analyzed from 13 such pts, some of whom had multiple specimens. Expression of EGFR and ERCC1 were detected in 77% and 92% of specimens tested. Expression of HER2 was detected in 47% and ER in 91% in samples tested. Discordance rates for the expression of the above 4 markers on the primary tumors vs. CTC were measured either before, during systemic treatment, or at progression on therapy. We observed significant discordance rates for all markers tested:ER 36%; ERCC1:20%; EGFR:60%; and HER2: 50%, respectively. Conclusions: Multiplex tumor marker testing of CTCs from pts with MBC is feasible. Following additional validation of expression patterns and the high discordance rates observed between CTCs and primary or metastatic tumor sites, prospective trials incorporating CTC expression into personalized treatment strategies may be justified.

Abstract
Numerical chromosome aberrations are incompatible with normal human development. Our laboratories develop hybridization-based screening tools that generate a maximum of cytogenetic information for each polar body or blastomere analyzed. The methods are developed considering that the abnormality might require preparation of case-specific probes and that only one or two cells will be available for diagnosis, most of which might be in the interphase stage. Furthermore, assay efficiencies have to be high, since there is typically not enough time to repeat an experiment or reconfirm a result prior to fertilization or embryo transfer. Structural alterations are delineated with breakpoint-spanning probes. When screening for numerical abnormalities, we apply a Spectral Imaging-based approach to simultaneously score as many as ten different chromosome types in individual interphase cells. Finally, DNA micro-arrays are under development to score all of the human chromosomes in a single experiment and to increase the resolution with which micro-deletions can be delineated.

Abstract
BACKGROUND Apoptosis is associated with the tumor grade in various types of carcinomas or lymphomas, but less is understood about the association of apoptosis in mesenchymal tumors. In the prior studies, expression of apoptotic regulatory proteins, Bcl-2, Fas and its ligand, Fas-ligand, has been related to apoptotic index (AI) and histopathological grade of tumors. Our study investigated the incidence of apoptosis in gastric smooth muscle tumor and the correlation of the apoptotic index (AI) with the histopathological grade of the tumors. We evaluated the relationship of apoptotic regulatory proteins to the AI and tumor grade. METHODS AND MATERIALS Using immunohistochemistry and the terminal deoxynucleotidyl transferase (TdT)-mediated digoxigenin-dUTP nick end-labeling (TUNEL) assay, we analyzed the expression of Bcl-2, Fas, Fas-ligand, and AI in 26 cases of gastric smooth muscle tumors. RESULTS The incidence of greater than 10 apoptotic cells per 10 high-power fields (HPFs) was 73% (19/26 cases). The AI was significantly associated with malignant tumors (P = 0.006) and mitotic counts (P = 0.006) but not with tumor size. Bcl-2, Fas, and Fas-ligand were detected in 13 (50%), 14 (53.8%), and 19 (73%) cases, respectively. Interestingly, Fas-ligand was significantly correlated to malignancy (P = 0.006), mitotic counts (P = 0.006), and AI (P = 0.035) but not to tumor size. Fas expression was significantly associated with high levels of AI (P = 0.014). In contrast, Bcl-2 expression was inversely associated with AI (P = 0.004). Expression of Bcl-2 and Fas did not show a statistically significant correlation with tumor grade, mitotic counts, or tumor size. CONCLUSION Apoptosis and Fas-ligand expression are statistically correlated to the histopathological grade of gastric smooth muscle tumors. This suggests that detection of apoptotic cells and Fas-ligand expression using the TUNEL assay or immunohistochemistry are useful for the evaluation of the malignant potential of gastric smooth muscle tumors.

Abstract
The guanidinium hydrochloride (GdnHCl)-induced unfolding of an all beta-sheet protein, the human acidic fibroblast growth factor (hFGF-1), is studied using a variety of biophysical techniques including multidimensional NMR spectroscopy. The unfolding of hFGF-1 in GdnHCl is shown to involve the formation of a stable equilibrium intermediate. Size exclusion chromotagraphy using fast protein liquid chromatography shows that the intermediate accumulates maximally at 0.96 m GdnHCl. 1-Anilinonapthalene 8-sulfonate binding, one-dimensional (1)H NMR, and limited proteolytic digestion experiments suggest that the intermediate has characteristics resembling a molten globule state. Chemical shift perturbation and hydrogen-deuterium exchange monitored by (1)H-(15)N heteronuclear single quantum coherence spectra reveal that profound structural changes in the intermediate state (in 0.96 m GdnHCl) occur in the C-terminal, heparin binding region of the protein molecule. Additionally, results of the stopped flow fluorescence experiments suggest that the kinetic refolding of hFGF-1 proceeds through the accumulation of an intermediate at low concentrations of the denaturant. To our knowledge, the present study is the first report wherein an equilibrium intermediate is characterized in detail in an all beta-barrel protein.

Abstract
We describe a type III restriction and modification (R/M) system, LlaFI, in Lactococcus lactis. LlaFI is encoded by a 12-kb native plasmid, pND801, harbored in L. lactis LL42-1. Sequencing revealed two adjacent open reading frames (ORFs). One ORF encodes a 680-amino-acid polypeptide, and this ORF is followed by a second ORF which encodes an 873-amino-acid polypeptide. The two ORFs appear to be organized in an operon. A homology search revealed that the two ORFs exhibited significant similarity to type III restriction (Res) and modification (Mod) subunits. The complete amino acid sequence of the Mod subunit of LlaFI was aligned with the amino acid sequences of four previously described type III methyltransferases. Both the N-terminal regions and the C-terminal regions of the Mod proteins are conserved, while the central regions are more variable. An S-adenosyl methionine (Ado-Met) binding motif (present in all adenine methyltransferases) was found in the N-terminal region of the Mod protein. The seven conserved helicase motifs found in the previously described type III R/M systems were found at the same relative positions in the LlaFI Res sequence. LlaFI has cofactor requirements for activity that are characteristic of the previously described type III enzymes. ATP and Mg2+ are required for endonucleolytic activity; however, the activity is not strictly dependent on the presence of Ado-Met but is stimulated by it. To our knowledge, this is the first type III R/M system that has been characterized not just in lactic acid bacteria but also in gram-positive bacteria.

Abstract
OBJECTIVE To assess the fetal heart rate (FHR) changes following external cephalic version using a computerized FHR monitor. STUDY DESIGN We performed 116 external cephalic versions on 106 pregnant women at 36-40 weeks' gestation. Tocolysis (magnesium sulfate) was given to 39 patients (34%). Computerized FHR monitoring was performed for 20-30 minutes before and for 20-30 minutes after the procedure. In addition, we analyzed the results of the FHR tracing obtained during the first 10 minutes following the procedure. RESULTS External cephalic version was successful in 40% of the patients. In the group of patients who were not treated with magnesium sulfate, FHR variation and the number of accelerations per 10 minutes were significantly reduced during the first 10 minutes following the procedure as compared with those factors on the FHR tracings obtained before or 20-30 minutes following the procedure (P < .05). In the group of patients who were treated with magnesium sulfate, FHR variation and the number of accelerations per 10 minutes were significantly reduced before and 10 minutes after the procedure as compared with the FHR tracings obtained 20-30 minutes following the procedure (P < .05). In both groups the basal FHR was significantly lower during the first 20-30 minutes following the procedure (P < .05). FHR decelerations were observed following the procedure in only two patients. None of the 106 fetuses had a low Apgar score or were admitted to the neonatal intensive care unit. CONCLUSION External cephalic version appears to be safe for the mother and fetus, although transient FHR changes may occur following the procedure.

Abstract
We determined the relative contributions of individual birthweight groups to the reduction in neonatal mortality rate (NMR) of US singleton livebirths from 1960 to 1986, the period during which neonatal intensive care was introduced and became established. Changes in the NMR for each race (non-white/white) and birthweight group were assessed in terms of three components of NMR (1) birthweight-specific neonatal mortality rate (BWS-NMR), (2) birthweight distribution, and (3) the interaction resulting from simultaneous changes in BWS-NMR and birthweight distribution. Overall, NMR decreased from 16.7 per 1000 livebirths in 1960 to 5.5 per 1000 livebirths in 1986. This reduction was achieved mainly by improvements in the BWS-NMRs of all birthweight groups. Neonates who weighted > 1.5 kg at birth were the major contributors to the overall reduction in the NMR; approximately two-thirds of total reduction in NMR between 1960 and 1980 and 52.6% of the total reduction between 1980 and 1986 occurred in the > 1.5 kg birthweight groups. Our study demonstrates that with the introduction of neonatal intensive care, survival of infants with birthweights > 1.5 kg improved markedly and that this improvement accounted for most of the decline in the neonatal mortality rate in the United States from 1960 to 1986. Therefore, in measuring the effectiveness of neonatal intensive care, the assessment should include not only very low birthweight (< 1.5 kg) but all birthweight groups.
