Abstract
The increasingly more stringent phosphorus (P) discharge limits, which are below the concentrations reliably achievable with currently available technologies, demand for better understanding of phosphorus removal mechanisms. This study investigated the compositional fractions of phosphorus (P) in various effluents as well as the efficacy of different levels of treatment processes for removing different fractions of P in wastewater. The results showed that BNR can effectively remove most fractions of P, with relatively higher efficiencies (>93%) towards bioavailable forms of P including soluble reactive P (sRP), particulate reactive P (pRP) portion and particulate acid hydrolysable P (pAHP) and, it showed relatively lower efficiency (78%) towards organic P. Soluble acid hydrolysable P (sAHP) was not effectively removed (<40%). Chemical P removal process was more effective for elimination of sRP, sAHP and particulate organic P (pOP), but was not as effective for removing pAHP and, it exhibited nearly no removal of dissolved organic P (DOP). We found that chemical P removal process led to a significant increase in the concentration of pRP by up to 255%, indicating that these pRP (presumably as chemically bounded P) are likely formed through chemical precipitation/co-adsorption. Only 22% and 64% of the pRP was removed through tertiary clarifier and filtration, respectively. This implies that chemical addition converts sRP into particulate-associated P, mostly as pRP that was not easily removed by sedimentation and filtration, therefore, the efficacy of chemical P removal highly depends on the effectiveness of solid and liquid separation process. As more sRP and particulate P were removed through the series of treatment processes, the percentage contribution from organic P increases with the level of treatment due to its recalcitrant nature. Our results indicated that in order to achieve extremely low effluent P levels, technologies and processes that can enhance pRP and DOP removal will be required.

Abstract
Diet-induced obesity is associated with changes in gastrointestinal function and induction of a mild inflammatory state. Serotonin (5-HT) containing enterochromaffin (EC) cells within the intestine respond to nutrients and are altered by inflammation. Thus, our aim was to characterize the uptake and release of 5-HT from EC cells of the rat ileum in a physiologically relevant model of diet-induced obesity. In chow-fed (CF) and Western diet-fed (WD) rats electrochemical methods were used to measure compression evoked (peak) and steady state (SS) 5-HT levels with fluoxetine used to block the serotonin reuptake transporter (SERT). The levels of mRNA for tryptophan hydroxylase 1 (TPH1) and SERT were determined by quantitative PCR, while EC cell numbers were determined immunohistochemically. In WD rats, the levels of 5-HT were significantly increased (SS: 19.2 ± 3.7 μm; peak: 73.5 ± 14.1 μm) compared with CF rats (SS: 12.3 ± 1.8 μm; peak: 32.2 ± 7.2 μm), while SERT-dependent uptake of 5-HT was reduced (peak WD: 108% of control versus peak CF: 212% control). In WD rats, there was a significant increase in TPH1 mRNA, a decrease in SERT mRNA and protein, and an increase in EC cells. In conclusion, our data show that foods typical of a Western diet are associated with an increased 5-HT availability in the rat ileum. Increased 5-HT availability is driven by the up-regulation of 5-HT synthesis genes, decreased re-uptake of 5-HT, and increased numbers and/or 5-HT content of EC cells which are likely to cause altered intestinal motility and sensation in vivo.

Abstract
Enzymes that degrade the amyloid β-peptide (Aβ) are important regulators of cerebral Aβ levels. High level of Aβ was found in the brain of diabetic patients and diabetic animals. Aim of the study was to investigate whether activities of Aβ-degrading enzymes neprilysin (NEP), endothelin-converting enzyme 1 (ECE-1) and insulin-degrading enzyme (IDE) were impaired in the brain of diabetic rats. Diabetes was induced in rats by ip administration of 65 mg/kg streptozotocin. The temporal cortex and hippocampus were obtained for activity and mRNA level assays of the three enzymes on the 35th day after induction. ECE-1 activity was significantly decreased both in the hippocampus and cortex of diabetic rats, while for IDE significantly lower activity occurred only in the cortex. NEP activity was slightly decreased in both brain regions. The hippocampus of diabetic rats showed significant decrease in mRNA levels of NEP and ECE-1 and moderate increase in IDE mRNA level. The cortex of diabetic rats showed slight decrease in mRNA levels of the three enzymes. The results indicated that the three Aβ-degrading enzymes were damaged to different extents in the brain of diabetic rats, and impairment of ECE-1 and IDE partly contributed to the elevated Aβ(1-40) levels in brain of diabetic rats.

Abstract
We report the first measurement of charged particle elliptic flow in Pb-Pb collisions at sqrt[S(NN)] =2.76 TeV with the ALICE detector at the CERN Large Hadron Collider. The measurement is performed in the central pseudorapidity region (|η|<0.8) and transverse momentum range 0.2<p t<5.0 GeV/c. The elliptic flow signal v₂, measured using the 4-particle correlation method, averaged over transverse momentum and pseudorapidity is 0.087 ± 0.002(stat) ± 0.003(syst) in the 40%-50% centrality class. The differential elliptic flow v₂ p t reaches a maximum of 0.2 near p t =3 GeV/c. Compared to RHIC Au-Au collisions at sqrt[S(NN)] 200 GeV, the elliptic flow increases by about 30%. Some hydrodynamic model predictions which include viscous corrections are in agreement with the observed increase.

Abstract
The first measurement of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at a center-of-mass energy per nucleon pair √ S NN = 2.76 TeV is presented. For an event sample corresponding to the most central 5% of the hadronic cross section, the pseudorapidity density of primary charged particles at midrapidity is 1584 ± 4(stat) ± 76(syst), which corresponds to 8.3 ± 0.4(syst) per participating nucleon pair. This represents an increase of about a factor 1.9 relative to pp collisions at similar collision energies, and about a factor 2.2 to central Au-Au collisions at √ S NN = 2.76 TeV. This measurement provides the first experimental constraint for models of nucleus-nucleus collisions at LHC energies.

Abstract
Abstract
Background: Breast cancer is a heterogeneous disease with different putative therapeutic targets based upon the particular subtype. The particular subtype can have profound implications for therapy, as in the case of basal-like carcinomas which tend to be more aggressive with less therapeutic options. Although many studies have examined the transition from Ductal Carcinoma in-situ (DCIS) to Invasive Breast Cancer (IBC), the mechanisms involving the transformation are poorly understood. DCIS cases that are more likely to progress to IBC can be treated more aggressively. This study used image analysis to examine the association between predictive molecular biomarkers between pure DCIS, DCIS associated with IBC and IBC.
Methods: With approval by the Institutional Review Board, we evaluated tissue microarrays comprising 453 tissue cores from 149 patients. Five immunohistochemical biomarkers were utilized: estrogen (ER), progesterone (PR), human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor (EGFR), and cytokeratin 5/6 (CK-5/6). We then employed the Automated Cellular Image Analysis (ACIS) to score the biomarker status. We compared regional scoring (rated 0, 1, 2, or 3) between an experienced pathologist's subjective assessment and an automated score derived from ACIS. An image library was generated and integrated to our Translational Data Mart (TraM: http://tram.uchicago. edu). Statistical analyses included a comparison of histological grade, race, age, tumor size, and lymph node status associated with the prevalence of subtypes between pure DCIS tumors and those that advanced to IBCs. Results: The concordance between ACIS-based and pathologist-based scoring was moderate (kappa = 0.38). There was more variability in the pathologist's scoring with a standard deviation of 1.14 as compared to 0.85 for ACIS. Subtypes associated with IBC were also present in DCIS. In the pure DCIS cases, there was a higher proportion of the luminal A subtype (74.1%, n = 54) as compared to DCIS adjacent to IBC (54.2%, n=24) or pure IBC cases (57.4%, n = 115) (p=0.05). In contrast, there was more basal-like subtypes in DCIS juxtaposed with IBC (20.8%) and IBC (27.8%) than in pure DCIS tumors (9.3%).
Discussion: Molecular subtype analysis of DCIS could be useful in predicting DCIS with high risk of progressing to invasive cancer. The resemblance between subtypes bolsters the hypothesis that IBCs and DCIS originate from the same precursor lesion. Although the automated scoring featured by ACIS would be useful in expediting readings, it must be validated by a pathologist's assessment.

Abstract
OBJECTIVES Schwann cell (SC) transplantation is a promising therapy for peripheral nerve transaction, however, clinical use of SCs is limited due to their very limited availability. Adipose-derived stem cells (ADSCs) have been identified as an alternative source of adult stem cells in recent years. The aim of this study was to evaluate the feasibility of using ADSCs as a source of stem cells for differentiation into Schwann-like cells by an indirect co-culture approach, in vitro. MATERIALS AND METHODS Multilineage differentiation potential of the obtained ADSCs was assayed by testing their ability to differentiate into osteoblasts and adipocytes. The ADSCs were co-cultured with SCs to be induced into Schwann-like cells through proximity, using a Millicell system. Expression of typical SC markers S-100, GFAP and P75NTR of the treated ADSCs was determined by immunocytochemical staining, western blotting and RT-PCR. Myelination capacity of the differentiated ADSCs (dADSCs) was evaluated in dADSC/dorsal root ganglia neuron (DRGN) co-cultures. RESULTS The treated ADSCs adopted a spindle shaped-like morphology after co-cultured with SCs for 6 days. All results of immunocytochemical staining, western blotting and RT-PCR showed that the treated cells expressed S-100, GFAP and P75NTR, indications of differentiation. dADSCs could form Schwann-like cell myelin in co-culture with DRGNs. Undifferentiated ADSCs (uADSCs) did not form myelin compared to DRGNs cultured alone, but could produce neurite extension. CONCLUSIONS These results demonstrate that this indirect co-culture microenvironment could induce ADSCs to differentiate into Schwann-like cells in vitro, which may be beneficial for treatment of peripheral nerve injuries in the near future.

Abstract
A 34-year-old man admitted to another hospital presented with sudden onset of headache. The CT scan was unremarkable, but magnetic resonance angiography revealed a fusiform aneurysm in the left vertebral artery. Six days later, the patient was sent to our institution for further diagnosis and treatment. Cerebral angiography confirmed a fusiform aneurysm located in the right vertebral artery. At first, we placed a neuroform-3 stent and could see contrast medium stasis in the aneurysm, so we did not fill coils into the aneurysm. Four months later, the patient was admitted for rechecking. DSA showed the aneurysm remained and we placed a LEO stent in the lumen of the Neuroform stent. A control DSA eight months later showed the aneurysm had almost healed. Overlapping stents may induce spontaneous thrombosis of vertebral artery aneurysms and facilitate parent artery reconstruction through flow remodeling and stent endothelialization. This technique may be an option in treating dissecting or fusiform intracranial aneurysms that are not amenable to open surgical treatment or endovascular coil embolization.

Abstract
The most frequent and devastating complication of the endovascular treatment of cerebral AVMs is hemorrhage. This report describes three patients with cerebral AVM who encountered bleeding during Onyx-18 embolization. The bleeding was discovered promptly during the procedure and hemorrhage quickly prevented using Onyx-18. All three patients recovered without any new neurological symptoms. Early detection and prevention of bleeding are very important during interventional procedures to avoid craniotomy and improve the prognosis of patients.

Abstract
1. Nine hundred and sixty 25-week-old Lohmann Brown layers were randomly divided into 5 groups with 216 layers in each group. Layers in group one were fed a control diet, group 2 received the control diet plus 20 mg/kg zinc bacitracin and 4 mg/kg colistinsulfate, and the remaining three groups received control diet plus 2000, or 4000, or 6000 mg/kg fructooligosaccharide (FOS). 2. The results showed improvements in egg production, feed consumption and feed conversion of layers when 2000 mg/kg FOS was added to the diets. 3. The results also showed some additional improvements in the group supplemented with 2000 mg/kg FOS, including increases in egg shell thickness, yolk colour and Haugh unit, and decreases in yolk cholesterol concentration. 4. However, larger (excessive) doses of FOS did not improve the performance of layers.

Abstract
Cysteinyl leukotrienes (CysLTs) are potent inflammatory mediators that induce inflammation through the activation of CysLT1 and CysLT2 receptors. It has been reported that inflammatory mediators, such as prostaglandins, play an important role in angiogenesis. However, whether CysLTs and the receptor subtypes are involved in angiogenesis is not clarified. Here, we determined the effects of CysLT receptor agonist leukotriene D4 (LTD4) and antagonists on angiogenesis by rat thoracic aortic ring assay. We found that the microvessel growth in 25% serum-containing cultures was significantly inhibited by the CysLT1 receptor antagonist montelukast (0.1-1 microM), but not by the CysLT2 receptor antagonist BAY cyslt2 (0.1-1 microM). The microvessel growth in serum-free culture was affected neither by montelukast (0.01-1 microM) nor by BAY cyslt2 (0.1-1 microM). Furthermore, LTD4 at 100 nM significantly enhanced the microvessel growth in serum-free culture and LTD4 at 10-100 nM significantly enhanced the microvessel growth in 25% serum-containing cultures. The enhancement was abrogated by both montelukast and BAY cyslt2. Thus, CysLT1 receptors may mediate endogenously regulated microvessel growth in normal culture; whereas the exogenous agonist LTD4 induces angiogenesis through the activation of both CysLT1 and CysLT2 receptors. The CysLT receptor antagonists can be developed as angiogenesis inhibitors.

Abstract
AIMS A major problem in industrial fermentation of organic acids with micro-organisms is to ensure a suitable pH in the culture broth. To circumvent this problem, we investigated the effect of citrate, which is a widely used auxiliary energy co-substrate, on cell growth, organic acid production and pH homeostasis among extracellular environment, cytoplasm and vacuole, in the pyruvic acid production by Candida glabrata CCTCC M202019 under different pH conditions. METHODS AND RESULTS Analysis of intracellular ATP regeneration, cytoplasmic and vacuolar pH values under different culture conditions points towards a relief of stress when C. glabrata is exposed to lower pH, if citrate is added. When 50 mmol l(-1) citrate was added to the culture medium, the intracellular ATP concentrations increased by 20·5% (pH 5·5), 20·4% (pH 5·0) and 39·3% (pH 4·5), and higher pH gradients among the culture broth, cell cytoplasm and vacuoles resulted. As a consequence, the cell growth and pyruvic acid production of C. glabrata CCTCC M202019 were significantly improved under pH 5·0 and 4·5. CONCLUSIONS The acid tolerance of yeast can be improved by enhancing the ATP supply, which helps to maintain higher pH gradients in the system. SIGNIFICANCE AND IMPACT OF THE STUDY The results presented here expand our understanding of the physiological characteristics in eukaryotic micro-organisms under low pH conditions and provide a potential route for the further improvement of organic acids production process by process optimization or metabolic engineering.

Abstract
We investigated the delta(15)N profile of N (extractable NH(4)(+), NO(3)(-), and organic N (EON)) in the soil of a N-saturated subtropical forest. The order of delta(15)N in the soil was EON > NH(4)(+) > NO(3)(-). Although the delta(15)N of EON had been expected to be similar to that of bulk soil N, it was higher than that of bulk soil N by 5 per thousand. The difference in delta(15)N between bulk soil N and EON (Delta(15)N(bulk-EON)) was correlated significantly with the soil C/N ratio. This correlation implies that carbon availability, which determines the balance between N assimilation and dissimilation of soil microbes, is responsible for the high delta(15)N of EON, as in the case of soil microbial biomass delta(15)N. A thorough delta(15)N survey of available N (NH(4)(+), NO(3)(-), and EON) in the soil profiles from the organic layer to 100 cm depth revealed that the delta(15)N of the available N forms did not fully overlap with the delta(15)N of plants. This mismatch in delta(15)N between that of available N and that of plants reflects apparent isotopic fractionation during N uptake by plants, emphasizing the high N availability in this N-saturated forest.

Abstract
Lower body negative pressure (LBNP) was applied in eight human subjects to trigger low frequency oscillations in order to study the nature of functional coupling between the hemodynamic and autonomic nervous systems, with particular focus on how the myogenic response fits within this coupling. To this end muscle sympathetic nerve activity (MSNA), mean arterial pressure (MAP), heart rate (HR), cardiac output (CO), and total peripheral resistance (TPR) were measured at baseline and during LBNP and were then examined in both the time and frequency domains. At the height of low frequency oscillations (~0.1Hz) there was a strong coupling between all the five indices, marked by perfect alignment of their oscillatory frequencies. Results in the time domain show that a fall in MAP is followed by a fall in TPR at 1.58s SD 0.69), a rise in heart rate at 2.64s (SD 0.98), a rise in cardiac output at 3.72s (SD 0.60), a peak in MSNA at 5.71s (SD 1.27) and, finally, a rise in TPR at 7.13s (SD 1.02). A possible interpretation of the latter is that a drop in MAP first triggers a drop in TPR via a myogenic response before the expected rise in TPR via a rise in MSNA. In other words, following a drop in arterial pressure, myogenic response controls vessel diameter before this control is taken over by MSNA. These findings provide a possible resolution of a longstanding conceptual argument against attributing a significant role for the myogenic response in blood flow autoregulation.
