Abstract
We investigate the ultrafast terahertz response of electrostatically gated graphene upon optical excitation. We observe that the photoinduced terahertz absorption increases in charge neutral graphene but decreases in highly doped graphene. We show that this transition from semiconductor-like to metal-like response is unique for zero bandgap materials such as graphene. In charge neutral graphene photoexcited hot carriers effectively increase electron and hole densities and increase the conductivity. In highly doped graphene, however, photoexcitation does not change net conducting carrier concentration. Instead, it mainly increases electron scattering rate and reduce the conductivity.

Abstract
Maize with high grain protein and oil contents offers great advantages for human food and animal feed. In this study, grain protein contents of 282 and 263 F7:8 recombinant inbred lines (RILs) of 2 crosses were evaluated in 4 environments within and between populations. The RILs were developed from crosses between an inbred high-oil maize line and 2 normal dent inbred maize lines. A total of 16 single-population QTLs and 19 joint-population QTLs were identified for protein content, and 21 QTLs were detected for protein-oil in each of the 4 environments tested and in combination. Most of the QTLs for protein content were greatly influenced by variation among populations and environments. Seven QTLs showed generational consistency compared with QTLs detected in the 2 F2:3 populations. However, 7 and 6 QTLs were detected in only the RIL and F2:3 populations, respectively. Protein and protein-oil QTLs with the same parental effects were detected at bins 3.03-3.05, 5.04-5.06, 6.03-6.05, 8.03-8.04, and 8.04-8.06, demonstrating that tightly linked and/or pleiotropic QTLs are controlling both traits at these bins. Four single-population QTLs and 11 joint-population QTLs identified at bins 3.02-3.03, 3.05, 7.01, 8.02, 8.03, 8.04-8.05, 8.05, 9.03, and 9.05 with intervals <5 cM could be used in marker-assisted selection. Along with the previously detected QTLs qPRO1-8-1 and qPRO1-5-1 at bins 8.03-8.04 and 5.02-5.04, the QTLs detected herein could be used to develop near isogenic lines and chromosome segment substitution lines in future studies.

Abstract
BACKGROUND Therapies that maintain remission for patients with Crohn's disease are essential. Stable remission rates have been demonstrated for up to 2 years in adalimumab-treated patients with moderately to severely active Crohn's disease enrolled in the CHARM and ADHERE clinical trials. AIM To present the long-term efficacy and safety of adalimumab therapy through 4 years of treatment. METHODS Remission (CDAI <150), response (CR-100) and corticosteroid-free remission over 4 years, and maintenance of these endpoints beyond 1 year were assessed in CHARM early responders randomised to adalimumab. Corticosteroid-free remission was also assessed in all adalimumab-randomised patients using corticosteroids at baseline. Fistula healing was assessed in adalimumab-randomised patients with fistula at baseline. As observed, last observation carried forward and a hybrid nonresponder imputation analysis for year 4 (hNRI) were used to report efficacy. Adverse events were reported for any patient receiving at least one dose of adalimumab. RESULTS Of 329 early responders randomised to adalimumab induction therapy, at least 30% achieved remission (99/329) or CR-100 (116/329) at year 4 of treatment (hNRI). The majority of patients (54%) with remission at year 1 maintained this endpoint at year 4 (hNRI). At year 4, 16% of patients taking corticosteroids at baseline were in corticosteroid-free remission and 24% of patients with fistulae at baseline had healed fistulae. The incidence rates of adverse events remained stable over time. CONCLUSIONS Prolonged adalimumab therapy maintained clinical remission and response in patients with moderately to severely active Crohn's disease for up to 4 years. No increased risk of adverse events or new safety signals were identified with long-term maintenance therapy. (clinicaltrials.gov number: NCT00077779).

Abstract
OBJECTIVE Nestin has been found to be overexpressed in several human malignancies. The primary goal of this research was to investigate whether nestin expression correlates with the occurrence and development of ovarian cancer. PATIENTS AND METHODS Expression of nestin was evaluated by immunohistochemistry in 315 cases of various epithelial ovarian lesions as well as 52 cases of normal ovarian epithelia. The association between nestin expression and various clinical pathological parameters was analysed. RESULTS Immunohistochemical results showed that the positive correlation of nestin expression gradually increased from benign and borderline to malignant ovarian tumours. Nestin overexpression was associated with more advanced International Federation of Gynaecology and Obstetrics stage and higher histological grade in serous adenocarcinoma. Nestin expression was significantly associated with chemoresistance. However, there was no significant correlation between nestin expression and the age and level of CA125 in patients. CONCLUSIONS We propose that nestin expression might contribute to the initiation, promotion, and progression of serous ovarian carcinoma; nestin expression is associated with poor chemoresponse. It could be a potential therapeutic target in patients with epithelial ovarian carcinoma.

Abstract
OBJECTIVE Chronic allograft nephropathy (CAN) is an important etiological factor causing graft loss. However, the mechanism of CAN is unclear. Osteopontin (OPN), a proinflammatory and profibrosis molecule, plays a key role in late stages of renal diseases. We investigated the potential role of OPN in the pathogenesis of CAN. METHODS Using a F344 to Lewis rat CAN model, we injected short hairpin RNA (shRNA) constructs targeting OPN or negative control plasmids through the renal vein following electroporation. At 12 weeks after the transplantation, we determined interstitial fibrosis (IF) and tubular atrophy (TA) of the tubular epithelial cells (TECs). OPN expression was examined using Western blots and immunohistochemistry (IHC). Molecules involved in epithelial to mesenchymal transition (EMT) of TECs were examined using IHC and Western blots. RESULTS OPN expression in kidney grafts was decreased by the RNA interference (RNAi) group. Histology observations showed IF and TA to be mild with stable renal function in the RNAi-treated group. EMT of TECs was significantly lessened after reducing OPN. CONCLUSION Reduction of OPN in vivo inhibited progression of CAN. OPN may be of therapeutic value in transplantation settings.

Abstract
PURPOSE To evaluate the efficacy of two-step retrograde closed stenting for treating canalicular laceration. methods: Forty-eight consecutive canalicular laceration cases (48 eyes) were randomised and divided into two groups: a one-step group and a two-step group. In the two-step group (23 cases), the first step was performed in the outpatient department and included identifying the medial cut end of the canaliculus and probing under a slit-lamp microscope, followed by a retrograde canalicular stenting assisted by a memory titanium stylet. The second step was canalicular anastomosis, which was performed in the operating room. In the one-step group (25 cases), all of the surgical procedures were performed when preoperative preparations were simultaneously available. RESULTS The time elapsed from the doctor visit to the treatment was 4.3 ± 2.4 h in the two-step group and 18.8 ± 6.3 h in the one-step group (P<0.01). The canalicular medial cut ends were found in all cases, but 8.6 ± 3.5 min was needed in the two-step group, and 51.4 ± 24.2 min was needed in the one-step group (P<0.01). The numerical rating scale for pain during surgery was 1.8 ± 1.2 in the two-step group and 5.4 ± 2.2 in the one-step group (P<0.01). One case (2.63%) in the two-step group and nine cases (36%) in the one-step group required other assisted methods to locate the medial cut end (P=0.007). Twenty-one cases (91.3%) in the two-step group and 20 cases (80%) in the one-step group achieved patent lacrimal drainage systems during a 12-month follow-up (P=0.528). CONCLUSIONS The two-step canalicular anastomosis method allows an early search for the medial cut end of the canaliculus and improves the chances of finding it; it is also a quicker, less invasive method for treating canalicular lacerations.

Abstract
Activation of human natural killer (NK) cells is associated with the cleavage of CD16 from the cell surface, a process mediated by matrix metalloproteinases (MMPs). In this report, we examined whether inhibition of MMPs would lead to improved NK cell antibody-dependent cell-mediated cytotoxicity (ADCC) function. Using an in-vitro ADCC assay, we tested the anti-tumour function of NK cells with three different therapeutic monoclonal antibodies (mAbs) in the presence of MMPs inhibitor GM6001 or its control. Loss of CD16 was observed when NK cells were co-cultured with tumour targets in the presence of specific anti-tumour antibodies, and was found particularly on the majority of degranulating NK responding cells. Treatment with MMPs inhibitors not only prevented CD16 down-regulation, but improved the quality of the responding cells significantly, as shown by an increase in the percentage of polyfunctional NK cells that are capable of both producing cytokines and degranulation. Furthermore, MMPs inhibition resulted in augmented and sustained CD16-mediated signalling, as shown by increased tyrosine phosphorylation of CD3ζ and other downstream signalling intermediates, which may account for the improved NK cell function. Collectively, our results provide a foundation for combining MMPs inhibitors and therapeutic mAbs in new clinical trials for cancer treatment.

Abstract
BACKGROUND The aim of this study was to evaluate the relationship between the severity of periodontitis and the extent and degree of coronary artery stenosis in a Chinese population. METHODS Patients (n = 853) with coronary artery stenosis confirmed by coronary angiography were eligible to take part in the study. Only subjects that were ≥60 years old, had ≥50% stenosis in at least one coronary artery, and did not have diabetes or a history of smoking were included (n = 115). After periodontal examination, including bleeding index, probing depth calculus index, plaque index and periodontal attachment loss, four groups were defined based on the severity of periodontitis: no periodontitis/gingivitis (M0, n = 19); mild periodontitis (M1, n = 27); moderate periodontitis (M2, n = 31); and severe periodontitis (M3, n = 38). The extent and degree of coronary artery stenosis was obtained by calculating the Gensini score (GS). RESULTS The GS was significantly greater in the M3 group compared with the M0 group. Multiple linear regression analysis revealed that probing depth and plaque index were significantly correlated with the GS. CONCLUSIONS The extent and severity of coronary artery stenosis in Chinese patients ≥60 years old is positively correlated with the severity of periodontitis.
