Abstract
PURPOSE To investigate within-test variability of the steady-state PERG (SS-PERG). METHODS SS-PERGs were recorded in response to black-white horizontal gratings (1.6 cycles/deg, 98% contrast, 15.63 reversals/s, LED display, 25 deg square field, 800 cd/sqm mean luminance) using skin electrodes. PERG and noise (± reference) signals were averaged over 1024 epochs (~ 2.2 min) and Fourier analyzed to retrieve SS-PERG amplitude and phase. SS-PERGs were split into 16 partial averages (samples) of 64 epochs each, and corresponding amplitudes and phases combined in polar coordinates to assess their dispersion (within-test variability). To assess time-dependent variability, samples were clustered in four successive time segments of ~ 33 s each. Amplitude adaptation was defined as amplitude difference between initial and final clusters, and PERG phase adaptation as the corresponding phase difference. To determine the dynamic range of SS-PERG adaptation, recording was performed in normal controls of different age (n = 32) and patients with different severity of optic nerve dysfunction (early manifest glaucoma, EMG, n = 7; non-arteritic ischemic optic neuropathy, NAION, n = 5). RESULTS Amplitude adaptation was largest in younger controls (amplitude adaptation ÷ noise, SNR = 9.5, 95% CI 13.1, 5.9) and progressively decreased with increasing age (older subjects, SNR = 5.5, 95% CI 9.2, 1.8) and presence of disease (EMG: SNR = 2.4, 95% CI 3.5, 1.4; NAION: SNR = 1.9, 95% CI 6.5,-2.2). In 11 young subjects, amplitude adaptation was repeatable (test-retest in two sessions a week apart; intraclass correlation coefficient = 0.59). Phase adaptation was not significantly different from zero in all groups. CONCLUSIONS SS-PERG adaptation accounts for a sizeable portion of the within-test variability. As it has robust SNR, sufficient test-retest variability, and is altered in disease, it may have physiological and clinical significance. This study suggests that SS-PERG protocols should include adaptation in addition to SS-PERG amplitude and phase/latency.

Abstract
The objective of this study was to ascertain whether mRNA and protein expressions of implantation-related genes (erythropoietin-producing hepatocellular receptor-ligand A1, Eph-ephrin A1 and leptin receptor-leptin, LEPR-LEP) differed between pigs with high and low number of embryos, and whether these differences in gene expression might affect embryo implantation. Experimental pig groups (n = 24) for high and low number of embryos were prepared by altering the number of eggs ovulated in pre-pubertal gilts treated with 1.5 × (High) or 1.0 × (Low) PG600 ([400 IU PMSG + 200 IU hCG]/dose, AKZO-NOBEL). Gilts expressing oestrus were artificially inseminated twice and maintained in breeding and gestation until the reproductive tract was collected on day 22 of pregnancy. At slaughter, the reproductive tracts from each pregnant gilt from each treatment were immediately processed to collect samples for RNA and protein analysis. Within each gilt, three conceptus points were sampled, one from each horn and then a random conceptus within the tract. At each conceptus point, endometrial attachment site, chorion-allantois and embryo were collected and immediately frozen in liquid nitrogen. Number of corpus luteum (CL) (35.4 vs. 12.6) and total embryo number (18.8 vs. 10.2) were greater in the high-embryo compared to the low-embryo group, respectively (p < .05). Real-time qPCR results showed that Eph-ephrin A1 mRNA expression was less in the high-embryo (p < .05) compared to the low-embryo group. In addition, Western blotting analysis indicated that Eph-ephrin A1 and LEP protein expression at endometrial attachment site in high-embryo was less (p < .05) compared to low-embryo group. It was also noted that mRNA expression of Eph-ephrin A1 and LEPR-LEP was greater in pregnant than non-pregnant gilts (p < .05). Moreover, mRNA expression of Eph-ephrin A1 (p < .05) and LEPR-LEP was greatest at endometrial attachment site among all three tissues. There was a positive correlation between expressions of Eph-ephrin A1, LEPR-LEP and embryo length with the correlation coefficient 0.31-0.59. For Eph-ephrin A1, the highest correlation coefficient appeared between Eph A1 expression and normal embryo number, between ephrin A1 expression and embryo length. For LEPR-LEP, the highest correlation coefficient appeared between LEPR-LEP expression and ovary weight (0.79 for both, p < .05), followed by embryo length and weight. The results of this study suggest that low expression of Eph-ephrin A1 and LEPR-LEP is somehow related to increased embryo number during implantation and that endometrial attachment site might be the main target tissue of these gene products. Yet, the increased expression of Eph-ephrin A1 and LEPR-LEP appeared associated with increased embryo growth (length and weight) and ovary weight, Eph-ephrin A1 and LEPR-LEP might play roles in the regulation of embryo implantation in pigs.

Abstract
Since hepatitis C virus (HCV) non-structural 3 (NS3) protease inhibitor (PI) combined with pegylated interferon/ribavirin (PR) has been approved for chronic HCV genotype (GT) 1b infection, a reliable and clinically useful predictor combining with serum HCV RNA to predict early virologic response, breakthrough, and relapse is important during HCV antiviral treatment. We evaluated the role of HCV NS3 antigen (HCV NS3Ag) on the prediction of virologic response in patients with HCV GT1b during PR or PR/simeprevir (triple) therapy. Three hundred patients were recruited, and HCV RNA and HCV NS3Ag were tested at baseline and weeks 2, 4, 12, 24, 48, and 72. NS3Ag and HCV RNA were significantly related (r(2) = 0.67) in the whole patient selection. The kinetic pattern of HCV RNA and HCV NS3Ag during triple treatment was similar. HCV NS3Ag levels in the triple group closely followed those of HCV RNA; the r(2) values were 0.756 (baseline), 0.837 (2 weeks), 0.989 (4 weeks), and 0.993 (12 weeks), respectively. For patients treated with PR, the positive and negative predictive values (PPVs and NPVs) for viral response were 96.31 % and 67.19 %, respectively, at week 4 by using the decrease of NS3Ag (dHCV NS3Ag) combined with HCV RNA. At week 12, the PPV was similar at 94.16 %, while the NPV reached 87.26 %. The PPV and NPV for the prediction of relapse and breakthrough were 90.6 % and 76.7 %, respectively. HCV NS3Ag is a valuable marker and could be a supplementary predictor of HCV RNA for the prediction of antiviral response, breakthrough, or relapse during HCV antiviral treatment.

Abstract
Calcium has an important role in regulating numerous cellular activities. However, extremely high levels of intracellular calcium can lead to neurotoxicity, a process commonly associated with degenerative diseases. Despite the clear role of calcium cytotoxicity in mediating neuronal cell death in this context, the pathological mechanisms remain controversial. We used a well-established Drosophila model of retinal degeneration, which involves the constitutively active TRPP365 channels, to study calcium-induced neurotoxicity. We found that the disruption of mitochondrial function was associated with the degenerative process. Further, increasing autophagy flux prevented cell death in TrpP365 mutant flies, and this depended on the PINK1/Parkin pathway. In addition, the retinal degeneration process was also suppressed by the coexpression of PINK1 and Parkin. Our results provide genetic evidence that mitochondrial dysfunction has a key role in the pathology of cellular calcium neurotoxicity. In addition, the results demonstrated that maintaining mitochondrial homeostasis via PINK1/Parkin-dependent mitochondrial quality control can potentially alleviate cell death in a wide range of neurodegenerative diseases.

Abstract
BACKGROUND AND PURPOSE Young ischaemic stroke patients often suffer from cognitive impairment after stroke. However, the risk factors of cognitive impairment are still unclear. This study examined the impact of vascular risk factors (VRFs) on cognitive impairment in first-ever young ischaemic stroke patients. METHODS Subjects were divided into low (0-1 VRF, n = 27), medium (2-3 VRFs, n = 45) and high-risk (≥4 VRFs, n = 12) groups according to their number of VRFs. The following VRFs were collected: hypertension, diabetes mellitus, dyslipidaemia, atrial fibrillation, obesity, smoking, excess alcohol consumption, coronary heart disease and hyperhomocysteinaemia. A battery of cognitive assessments was executed 2 weeks after stroke. Differences of cognitive performances between groups were compared. The correlation between VRFs and cognitive function was investigated with an emphasis on discovering the main VRFs. RESULTS Eighty-four patients were enrolled in this study eventually. Compared with the low-risk group, the high-risk group had significantly worse performance in most of the cognitive domains. VRFs had a correlation with general cognition, executive function, attention and verbal fluency. After adjusting the covariates, VRFs showed a linear correlation with global cognitive function (R = 0.640, P = 0.000), verbal fluency (R = 0.372, P = 0.000), delayed memory (R = 0.327, P = 0.002), visual attention (R = 0.290, P = 0.007) and executive function (R = 0.266, P = 0.015). Amongst all the VRFs, hypertension, hyperlipidaemia, smoking and hyperhomocysteinaemia were the main influencing VRFs. CONCLUSION Vascular risk factors aggravate cognitive impairment after young ischaemic stroke. Effective management of VRFs in young adults is urgent and this may reduce the cognitive impairment.

Abstract
Inflammation instigated by interleukin (IL)-17-producing cells is central to the development and pathogenesis of several human autoimmune diseases and animal models of autoimmunity. The expansion of IL-17-producing cells from healthy donors is reportedly promoted by mesenchymal stem cells derived from fetal bone marrow. In the present study, human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) were examined for their effects on lymphocytes from healthy donors and from patients with systemic lupus erythematosus (SLE). Significantly higher levels of IL-17 were produced when CD4(+) T cells from healthy donors were co-cultured with hUC-MSCs than those that were cultured alone. Blocking experiments identified that this effect might be mediated partially through prostaglandin E2 (PGE2 ) and IL-1β, without IL-23 involvement. We then co-cultured hUC-MSCs with human CD4(+) T cells from systemic lupus erythematosus patients. Ex-vivo inductions of IL-17 by hUC-MSCs in stimulated lymphocytes were significantly higher in SLE patients than in healthy donors. This effect was not observed for IL-23. Taken together, our results represent that hUC-MSCs can promote the IL-17 production from CD4(+) T cells in both healthy donor and SLE patients. PGE2 and IL-1β might also be partially involved in the promotive effect of hUC-MSCs.

Abstract
BACKGROUND The OPTIMAL study was the first study to compare efficacy and tolerability of the epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) erlotinib, versus standard chemotherapy in first-line treatment of patients with EGFR mutation-positive advanced non-small-cell lung cancer (NSCLC). Findings from final overall survival (OS) analysis and assessment of post-study treatment impact are presented. PATIENTS AND METHODS Of 165 randomised patients, 82 received erlotinib and 72 gemcitabine plus carboplatin. Final OS analyses were conducted when 70% of deaths had occurred in the intent-to-treat population. Subgroup OS was analysed by Cox proportional hazards model and included randomisation stratification factors and post-study treatments. RESULTS Median OS was similar between the erlotinib (22.8 months) and chemotherapy (27.2 months) arms with no significant between-group differences in the overall population [hazard ratio (HR), 1.19; 95% confidence interval (CI) 0.83-1.71; P = 0.2663], the exon 19 deletion subpopulation (HR, 1.52; 95% CI 0.91-2.52; P = 0.1037) or the exon 21 L858 mutation subpopulation (HR, 0.92; 95% CI 0.55-1.54; P = 0.7392). More patients in the erlotinib arm versus the chemotherapy arm did not receive any post-study treatment (36.6% versus 22.2%). Patients who received sequential combination of EGFR-TKI and chemotherapy had significantly improved OS compared with those who received EGFR-TKI or chemotherapy only (29.7 versus 20.7 or 11.2 months, respectively; P < 0.0001). OS was significantly shorter in patients who did not receive post-study treatments compared with those who received subsequent treatments in both arms. CONCLUSION The significant OS benefit observed in patients treated with EGFR-TKI emphasises its contribution to improving survival of EGFR mutant NSCLC patients, suggesting that erlotinib should be considered standard first-line treatment of EGFR mutant patients and EGFR-TKI treatment following first-line therapy also brings significant benefits to those patients.

Abstract
Determining the insertion position of an exogenous gene in the target plant genome is one of the main issues in the transgenic plant field. This study introduced a simple, rapid, and accurate method to clone the flanking sequences of the transgenic bar gene as the anchoring gene in the transgenic maize genome using single-primer polymerase chain reaction (PCR). This method was based on the distribution of restriction sites in the maize genome and adopted the single-primer PCR method. Cloning the flanking sequences with the restriction site-anchored single-primer PCR simplified the experimental procedures by about 70% and reduced the experimental time by more than 80%. In conclusion, the restriction site-anchored single-primer PCR was a simple, rapid method to obtain the unknown flanking sequences in the transgenic plants.

Abstract
The aim of this study was to visualize bony defects of the palate and vomer in submucous cleft palate patients (SMCP) by three-dimensional (3D) computed tomography (CT) reconstruction and to classify the range of bony defects. Forty-eight consecutive non-operated SMCP patients were included. Diagnosis was based on the presence of at least one of three classical signs of SMCP: bifid uvula, a translucent zone in the midline of the soft palate, and a palpable 'V' notch on the posterior border of the bony palate. Patients were imaged using spiral CT. 3D reconstruction models were created of the palate and vomer. The sagittal extent of the bony cleft in SMCP was classified into four types: type I, no V-shaped hard palate cleft (8.3%); type II, cleft involving the partial palate (43.8%); type III, cleft involving the complete palate and extending to the incisive foramen (43.8%); type IV, cleft involving the complete palate and the alveolar bone (4.2%). The extent of the vomer defect was classified into three types: type A, vomer completely fused with the palate (8.3%); type B, vomer partially fused with the palate (43.8%); type C, vomer not fused with the palate up to the incisive foramen (47.9%). Significant variability in hard palate defects in SMCP is the rule rather than the exception. The association of velopharyngeal insufficiency with anatomical malformations may be complex.
