Abstract
Hypertensive disorders complicating pregnancy (HDCP) is one of the most serious medical disorders during pregnancy. Hydrogen is a therapeutic antioxidant and used to treat HDCP effectively. However, the molecular mechanism about the effect of hydrogen on HDCP still remains unclear. In this study, we found ROS content in HDCP group was significantly higher than that in the control and was reduced markedly in the presence of 100μmol/L hydrogen. IL6, Caspase3, Bax1, P-JAK2, P-Stat3 and P-p38 expression was much higher than the control, and was notably decreasedby the application of 100μmol/L hydrogen. Bcl2 expression in HDCP group was notably lower than the control and was increased by 100 μmol/L hydrogen. The apoptosis rate of cytotrophoblast cells was decreased, andratio of cytotrophoblast cells at G1 and G2 phase was increased and decreased by hydrogen, respectively. All those data indicated a potential molecular mechanism of hydrogen-mediated treatment in HDCP.

Abstract
Chronic lung allograft dysfunction, the major cause of death following lung transplantation, usually manifests as irreversible airflow obstruction associated with obliterative bronchiolitis (OB), a lesion characterized by chronic inflammation, lymphoid neogenesis, fibroproliferation and small airway obliteration. Spleen tyrosine kinase (Syk), a tyrosine kinase that regulates B cell function and innate immunity, has been implicated in the pathogenesis of chronic inflammation and tissue repair. This study evaluated the role of Syk in development of OB, using an intrapulmonary tracheal transplant model of OB with the conditional Syk-knockout Syk(flox/flox) //rosa26-CreER(T2) mice and a Syk-selective inhibitor, GSK2230413. BALB/c trachea allografts were transplanted into Syk-knockout (Syk(del/del) ) mice or wild-type C57BL/6 recipients treated with GSK2230413. At day 28, histological analysis revealed that in the Syk(del/del) and GSK2230413-treated C57BL/6 recipients, the graft lumen remained open compared with allografts transplanted into Syk-expressing (Syk(flox/flox) ) and placebo control-treated C57BL/6 recipients. Immunofluorescence showed lymphoid neogenesis with distinct B and T cell zones in control mice. In contrast, lymphoid neogenesis was absent and few B or T cells were found in Syk(del/del) and GSK2230413-treated mice. These observations suggest that inhibition of Syk may be a potential therapeutic strategy for the management of OB following lung transplantation.

Abstract
Rabies remains an enigmatic and widely discussed global infectious disease and causes an increasing number of deaths. The currently used highly effective prophylactic and post exposure (p.e.) vaccination depends solely upon inexpensive, effective and safe vaccines to counteract the spread of the disease. In this study, the potential of an attenuated Chinese rabies vaccine (SRV9) strain in prophylactic and p.e. vaccination against the street strain of rabies virus (RV) was evaluated in mice. Prophylactic vaccination consisting of one intramuscular (i.m.) dose of SRV9 protected 100% of mice from intracerebral (i.c.) challenge with a lethal dose of the street virus. The latter was detected in the brain of mice at day 6 post challenge by RT-PCR. Post exposure vaccination was performed at days 1, 2, 3, 4, 5 and 6 post infection (p.i.) with either SRV9 or inactivated rabies vaccine. The survival rates after i.m. inoculation of SRV9 at the indicated days were 70%, 50%, 30%, 20%, 10%, and 0%, respectively; the corresponding survival rates for the inactivated rabies vaccine were 30%, 20%, 10%, 0%, 0%, and 0%, respectively. However, 100%, 90%, 70%, 50%, 20%, 10%, and 10% of mice survived after i.c. inoculation of SRV9 at the indicated days. The increased permeability of the blood-brain barrier and the infiltration of CD19+ B cells into the central nervous system after i.c. inoculation of SRV9 are regarded as prerequisites for the clearance of the street virus. The obtained data suggest that SRV9 is a promising candidate for prophylactic and p.e. vaccination against rabies infection and that it exhibits a potential for the control of rabies in China.

Abstract
In this study, inter-simple sequence repeats (ISSRs) and sequence-related amplified polymorphism (SRAP) were applied to assess the genetic diversity in 38 species of Chrysanthemum and related genera. A total of 204 and 567 bands were amplified by 24 ISSR and 25 SRAP primers, of which 196 (97%) and 557 (99%) were polymorphic, respectively. The ISSR-based genetic similarity ranged from 0.016 to 0.886 and averaged 0.201, while the SRAP-based genetic similarity varied from 0.010 to 0.811 and averaged 0.122. Both the ISSR and SRAP techniques revealed similar clustering patterns and grouped species of Chrysanthemum and Ajania together. The results of principal coordinate analysis corroborated the unweighted pair group method with arithmetic average clustering. Additionally, results from ISSR and SRAP data were significantly correlated (r = 0.89, P < 0.001). Knowledge about genetic diversity among species can aid the transfer of traits of interest from the wild into cultivated chrysanthemum in future distant interspecific breeding.

Abstract
Classic tissue recombination studies have demonstrated that, in the early developing mouse tooth germ, the odontogenic potential, known as the tooth-inductive capability, resides initially in the dental epithelium and then shifts to the dental mesenchyme. However, it remains unknown if human embryonic dental tissues also acquire such odontogenic potential. Here we present evidence that human embryonic dental tissues indeed possess similar tooth-inductive capability. We found that human dental epithelium from the cap stage but not the bell stage was able to induce tooth formation when confronted with human embryonic lip mesenchyme. In contrast, human dental mesenchyme from the bell stage but not the cap stage could induce mouse embryonic second-arch epithelium as well as human keratinocyte stem cells, to become enamel-secreting ameloblasts. We showed that neither post-natal human dental pulp stem cells (DPSCs) nor stem cells from human exfoliated deciduous teeth (SHED) possess odontogenic potential or are odontogenic-competent. Our results demonstrate a conservation of odontogenic potential in mouse and human dental tissues during early tooth development, and will have an implication in the future generation of stem-cell-based bioengineered human replacement teeth.

Abstract
The purpose of the study was to examine the effect of lentivirus-mediated IL-10 gene therapy to target lung allograft rejection in a mouse orthotopic left lung transplantation model. IL-10 may regulate posttransplant immunity mediated by IL-17. Lentivirus-mediated trans-airway luciferase gene transfer to the donor lung resulted in persistent luciferase activity up to 6 months posttransplant in the isograft (B6 to B6); luciferase activity decreased in minor-mismatched allograft lungs (B10 to B6) in association with moderate rejection. Fully MHC-mismatched allograft transplantation (BALB/c to B6) resulted in severe rejection and complete loss of luciferase activity. In minor-mismatched allografts, IL-10-encoding lentivirus gene therapy reduced the acute rejection score compared with the lentivirus-luciferase control at posttransplant day 28 (3.0 ± 0.6 vs. 2.0 ± 0.6 (mean ± SD); p = 0.025; n = 6/group). IL-10 gene therapy also significantly reduced gene expression of IL-17, IL-23, and retinoic acid-related orphan receptor (ROR)-γt without affecting levels of IL-12 and interferon-γ (IFN-γ). Cells expressing IL-17 were dramatically reduced in the allograft lung. In conclusion, lentivirus-mediated IL-10 gene therapy significantly reduced expression of IL-17 and other associated genes in the transplanted allograft lung and attenuated posttransplant immune responses after orthotopic lung transplantation.

Abstract
BACKGROUND The gastrointestinal effects of antimuscarinic drugs used to treat overactive bladder may be related to the selectivity of these agents for M(3) -muscarinic receptor subtypes. We compared the effects of non-selective (fesoterodine) and M(3)-selective (solifenacin) antimuscarinics on gastrointestinal transit in healthy women. METHODS Gastric emptying (GE), small-intestinal transit (colonic filling at 6 h), colonic transit [geometric center at 24 h (GC24; primary endpoint) and 48 h (GC48)], and bowel habits were assessed by scintigraphy and bowel diaries before and after randomization to fesoterodine 8 mg, solifenacin 10 mg, or placebo (2 : 2 : 1) for 14 days. An interim analysis to finalize sample size was conducted. KEY RESULTS After 60 subjects [placebo (n = 12), fesoterodine (n = 25), solifenacin (n = 23)] completed the study, the study was terminated due to a prespecified criterion (sample size ≥ 452.5 needed to provide ≥ 80% power to demonstrate superiority of fesoterodine over solifenacin in GC24). Compared with baseline, (i) placebo delayed small-intestinal, but not colonic, transit, (ii) fesoterodine significantly increased GE t(1/2) vs placebo (17.0 min; P = 0.027), and (iii) fesoterodine and solifenacin delayed small-intestinal (-36.8% and -21.8%, respectively, P < 0.001 vs placebo) and colonic transit (GC24: -0.44 and -0.49, respectively, P < 0.05 vs placebo; GC48: -0.25 and -0.65, respectively, P > 0.05 vs placebo). Solifenacin increased stool hardness from baseline (P = 0.010 for difference vs fesoterodine); stool frequency was comparable. CONCLUSIONS & INFERENCES In healthy women, fesoterodine had greater effects on small-intestinal transit and solifenacin had greater effects on colonic transit; the latter finding may explain why solifenacin, but not fesoterodine, increased stool hardness.

Abstract
AIM The aim of this study was to assess the effect of apical lymph node (APN) metastasis in predicting prognosis in curatively treated node-positive rectal cancer. We also investigated the relationship between APN metastasis and the total number of metastatic lymph nodes. METHOD A retrospective study was performed of 510 curatively treated patients with node-positive rectal cancer. Clinicopathological variables, including APN status, were assessed in univariate and multivariate analyses. The prognostic significance of APN status in predicting patient outcomes and the relationship between APN status and American Joint Committee on Cancer (AJCC) N stage were analysed. RESULTS At a median follow up of 47 months, the 5-year local recurrence (LR) rate, the disease-free survival (DFS) rate and the overall survival (OS) rate were 18.3%, 55.5% and 58.8%, respectively. The 5-year OS rate was 69.6% for patients with no metastasis in APNs (APN(-)) and 40.8% for patients with metastasis in APNs (APN(+)). DFS and OS for patients with undetermined APN status were between those for APN(-) and APN(+). Subgroup analysis gave a 5-year OS rate of 48.7% in Stage N1 patients with APN(+) and 58.8% for Stage N2 patients with APN(-) (P = 0.0004). CONCLUSION APN metastasis is an important prognostic factor in node-positive rectal cancer, which provides additional survival-related prognostic classification irrespective of N stage. As the APN is usually outside the radiation field, in the era of multidisciplinary treatment its assessment should be incorporated into prognostic evaluation of rectal cancer.

Abstract
A full-length cDNA homologue of SOS1 (salt overly sensitive 1) was isolated from the salinity-tolerant species Chrysanthemum crassum and found to encode a Na(+) /H(+) antiporter, using degenerate PCR and RACE-PCR. The 3752-bp sequence comprised a 3438 bp open reading frame, encoding a 127-kDa protein with 12 transmembrane domains within its N terminal portion, and a hydrophilic cytoplasmic tail in its C-terminal portion. CcSOS1 appears to be a plasma membrane protein, and shares ∼62% identity at the peptide level with its Arabidopsis thaliana homologue. Expression of CcSOS1 in the roots of C. crassum was sensitive to salinity stress, while in the leaves CcSOS1 was down-regulated in the presence of abscisic acid. CcSOS1 transcript abundance was reduced in both roots and leaves of plants exposed to low temperature, while it was increased in leaves (but not in roots) after drought stress. CcSOS1 expression was not regulated in the presence of CaCl2 . A heterologous complementation assay in yeast suggested that CcSOS1 directs Na(+) efflux, mimicking the function of the endogenous NHA1 protein. Thus CcSOS1 appears to encode a salinity-inducible plasma membrane Na(+) /H(+) antiporter. This gene may be useful in transgenic approaches to improving the salinity tolerance of related ornamental species.

Abstract
Congenital disorders of glycosylation (CDG) are caused by a dysfunction of glycosylation, an essential step in the manufacturing process of glycoproteins. This paper focuses on a 6-year-old patient with a new type of CDG-I caused by a defect of the steroid 5α reductase type 3 gene (SRD5A3). The clinical features were psychomotor retardation, pathological nystagmus, slight muscular hypotonia and microcephaly. SRD5A3 was recently identified encoding the polyprenol reductase, an enzyme catalyzing the final step of the biosynthesis of dolichol, which is required for the assembly of the glycans needed for N-glycosylation. Although an early homozygous stop-codon (c.57G>A [W19X]) with no functional protein was found in the patient, about 70% of transferrin (Tf) was correctly glycosylated. Quantification of dolichol and unreduced polyprenol in the patient's fibroblasts demonstrated a high polyprenol/dolichol ratio with normal amounts of dolichol, indicating that high polyprenol levels might compete with dolichol for the initiation of N-glycan assembly but without supporting normal glycosylation and that there must be an alternative pathway for dolichol biosynthesis.

Abstract
Despite potential benefits, primary care clinicians may avoid using antimuscarinics in men with overactive bladder (OAB) symptoms because of safety concerns. To review the efficacy and safety of antimuscarinics, alone or in combination with an α-blocker, for the treatment of men with OAB symptoms, we conducted a systematic review of articles published before 22 July 2010, using PubMed. Data from 12-week, randomised, double-blind, placebo-controlled trials of tolterodine extended release (ER), oxybutynin and solifenacin show that combined antimuscarinic+α-blocker treatment is generally more effective than monotherapy or placebo in men with OAB symptoms. The efficacy and safety of tolterodine ER+α-blocker treatment was not affected by prostate size or prostate-specific antigen (PSA) level. In men meeting entry criteria for OAB and benign prostatic obstruction trials, tolterodine ER alone was effective selectively in men with prostate size or PSA level below study medians. Incidence of acute urinary retention (AUR) in men receiving antimuscarinics with or without an α-blocker was ≤3% in all of these trials; changes in postvoid residual volume and maximum flow rate did not appear clinically meaningful. Post hoc analyses from double-blind, placebo-controlled trials and prospective studies of fesoterodine, oxybutynin, propiverine, solifenacin and tolterodine also suggest that antimuscarinics are generally safe and efficacious in men. A retrospective database study found that risk of AUR in men was the highest in the first month of treatment and decreased considerably thereafter. Antimuscarinics, alone or with an α-blocker, appear to be efficacious and safe in many men with predominant OAB symptoms or persistent OAB symptoms despite α-blocker or 5-α-reductase inhibitor treatment. However, antimuscarinics are not approved for the treatment of benign prostatic hyperplasia. Monitoring men for AUR is recommended, especially those at increased risk, and particularly within 30 days after starting antimuscarinic treatment.

Abstract
Abstract
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system (CNS). It is reported that cerebrospinal fluid from MS patients during relapse contains higher levels of MIF than samples collected during remission. While the potent pro-inflammatory properties of MIF are well established, the precise contribution to neuroinflammation is not well defined. We have previously shown that despite their ability to generate pathogenic T cells, MIF-/- mice fail to develop experimental autoimmune encephalomyelitis (EAE), and have reduced CNS pathology. These findings suggest that MIF acts within the CNS to potentiate disease progression. We observed that MIF-treated microglia upregulate inflammatory mediators associated with MS and EAE including IL-1, IL-6, TNF-α, iNOS, and CCL2, and exhibit morphological changes consistent with activation. We extended these findings in vivo, performing stereotactic spinal microinjection of rMIF into naïve mice, which resulted in targeted microglial reactivity and cellular infiltration. To determine the role of MIF in the CNS during EAE, we examined the ability of rMIF spinal microinjection to restore CNS pathology in MIF-/- mice. Notably, rMIF microinjection was sufficient to restore CNS pathology in EAE-resistant MIF-/- mice following induction of EAE. Taken together, these studies implicate MIF as a CNS inflammatory mediator that may contribute to the development and maintenance of MS lesions.

Abstract
The potential of detecting the hyperfine interaction at the nuclear site of radioactive isotopes for the investigation of nanocrystalline (nc) materials is discussed. The subject is illustrated with help of different examples for characterizing nc samples. Using the perturbed γ
γ angular correlation technique (PAC) for detecting the hyperfine interaction at the site of the radioactive probe 111In/111Cd experiments regarding the doping of nc semiconductors ZnO and InP, the shift of the Néel temperature in nc antiferromagnetic NiO, the structure of grain boundaries in Ni, and the homogeneity of nc Ni-Cu alloys are presented. The resulting information is compared with that obtained by Mössbauer spectroscopy and by standard techniques used in materials science.

Abstract
AIMS To evaluate the efficacy and tolerability of flexible-dose fesoterodine in subjects with overactive bladder (OAB) who were dissatisfied with previous tolterodine treatment. METHODS This was a 12-week, open-label, flexible-dose study of adults with OAB (> or = 8 micturitions and > or = 3 urgency episodes per 24 h) who had been treated with tolterodine (immediate- or extended-release) for OAB within 2 years of screening and reported dissatisfaction with tolterodine treatment. Subjects received fesoterodine 4 mg once daily for 4 weeks; thereafter, daily dosage was maintained at 4 mg or increased to 8 mg based on the subject's and physician's subjective assessment of efficacy and tolerability. Subjects completed 5-day diaries, the Patient Perception of Bladder Condition (PPBC) and the Overactive Bladder Questionnaire (OAB-q) at baseline and week 12 and rated treatment satisfaction at week 12 using the Treatment Satisfaction Question (TSQ). Safety and tolerability were assessed. RESULTS Among 516 subjects treated, approximately 50% opted for dose escalation to 8 mg at week 4. Significant improvements from baseline to week 12 were observed in micturitions, urgency urinary incontinence episodes, micturition-related urgency episodes and severe micturition-related urgency episodes per 24 h (all p < 0.0001). Approximately 80% of subjects who responded to the TSQ at week 12 reported satisfaction with treatment; 38% reported being very satisfied. Using the PPBC, 83% of subjects reported improvement at week 12 with 59% reporting improvement > or = 2 points. Significant improvements from baseline (p < 0.0001) exceeding the minimally important difference (10 points) were observed in OAB-q Symptom Bother and Health-Related Quality of Life (HRQL) scales and all four HRQL domains. Dry mouth (23%) and constipation (5%) were the most common adverse events; no safety issues were identified. CONCLUSION Flexible-dose fesoterodine significantly improved OAB symptoms, HRQL, and rates of treatment satisfaction and was well tolerated in subjects with OAB who were dissatisfied with prior tolterodine therapy.

Abstract
In this randomized, double-blind study, 126 mild to moderate essential hypertensive patients from northern China were studied to determine the efficacy and safety of a combination therapy of valsartan and hydrochlorothiazide. Patients were randomized to the V80/H12.5 (80 mg valsartan/12.5 mg hydrochlorothiazide) group or the V80 (80 mg valsartan) group. Six weeks after treatment, the mean decrease from baseline in mean sitting systolic blood pressure (MSSBP) was significantly higher in the V80/H12.5 group than the V80 group, but there was no difference in the change of mean sitting diastolic blood pressure (MSDBP) in the two groups. Overall, 80.33% and 70.97% had a controlled response (normalized MSDBP), and 85.25% and 77.42% had a diastolic response (normalized MSDBP or > 10 mmHg reduction in MSDBP) in the V80/H12.5 and V80 groups, respectively (not significantly different). The incidence of adverse events was also similar between the two groups. The combination of 80 mg valsartan/12.5 mg hydrochlorothiazide was efficacious and well tolerated in mild and moderate essential hypertensive patients.

Abstract
Clinical trials and observations suggest that constipation is an uncommon side effect of treating overactive bladder with the muscarinic receptor antagonist tolterodine. Because muscarinic antagonism inhibits gastrointestinal motor activity, we evaluated the effects of tolterodine on bowel habits, gastrointestinal and colonic transit in healthy subjects. In this double-blind study, 36 healthy subjects were randomized to tolterodine extended release (ER, 4 mg daily) or placebo for 6 days. Gastric emptying (GE), small bowel and colonic transit were assessed on days 4-6 by scintigraphy. Bowel habits were recorded by diaries. Tolterodine did not significantly affect half-time for GE (GE t(half)) [116 +/- 6 min (mean +/- SEM) for placebo vs 126 +/- 7 min for tolterodine], small bowel transit measured by colonic filling at 6 h (45 +/- 6% for placebo vs 36 +/- 6% for tolterodine) or the geometric center of colonic transit at 24 h (2.9 +/- 0.2 for placebo vs 2.6 +/- 0.3 for tolterodine). Subjects who received tolterodine had slightly fewer bowel movements (i.e. 1.34 +/- 0.1 stools per day for placebo vs 1.0 +/- 0.1 for tolterodine; P = 0.02 for treatment effect). Tolterodine did not significantly affect stool consistency or ease of defecation. At the therapeutic dose used to treat overactive bladder, tolterodine did not significantly affect gastrointestinal or colonic transit and had minor effects on bowel habits in healthy subjects. Further studies are necessary to elucidate whether these observations are explained by tolterodine effects at muscarinic receptors which stimulate and inhibit gastrointestinal motility.

Abstract
The Constructionarium initiative can be classified as the implement section of the conceive, design, implement, operate (CDIO) innovative educational framework for civil engineering students. CDIO is an international learning and teaching initiative which is based on the principle of embedding active learning into engineering education at all levels. The Constructionarium provides a practical construction experience for various civil engineering structures such as a gravity concrete oil rig, a cable-stayed steel bridge, a transmission tower, a subway entrance hall and a clay core dam, all at a reduced scale. Students are required to follow the same professional and health and safety procedures that a construction contractor follows on a real construction project. A collaborating construction contractor and a design consultant offer close supervision, support and guidance for all site activities, typically covering preparation of method statements, risk assessments, construction planning, costing, setting-out, use of construction tools, and so on. The Constructionarium is a concentrated learning week for students for which there is no other equivalent replacement activity. In this paper, the Liverpool Constructionarium is presented in detail, including pre-Constructionarium preparation, learning objectives, running projects, associated problems and learning outcomes. In addition the results from pre- and post-Constructionarium questionnaires are presented to show measurement of learning outcomes from student feedback.
