      • Toward high efficiency organic photovoltaic devices with enhanced thermal stability utilizing P3HT-b-P3PHT block copolymer additives

        Zhu, M.,Kim, H.,Jang, Y.,Park, S.,Ryu, D.,Kim, K.,Tang, P.,Qiu, F.,Kim, D.,Peng, J. Royal Society of Chemistry 2016 Journal of Materials Chemistry A Vol.4 No.47

        <P>Organic photovoltaics (OPVs) have drawn an extensive amount of attention due to their low cost, processibility and flexibility. However, a cell based on a blend of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C-61-butyric acid methyl ester (PC61BM) has a limited power conversion efficiency (PCE) due to the short exciton diffusion length of similar to 10 nm. We address this issue by designing a series of all-conjugated diblock copolymers, poly(3-hexylthiophene)-b-poly(3-(6-diethylphosphonatohexyl) thiophene) (P3HT-b-P3PHT), intended for use as additives to improve the performance of P3HT:PC61BM-based photovoltaic devices. The PCE of the devices improved from 3.30% to 4.03% with the addition of P3HT-b-P3PHT (3 : 1). The thermal stability of devices with P3HT-b-P3PHT additives improved significantly relative to that of the P3HT:PC61BM reference device, where the devices including a copolymer with a higher P3PHT content exhibited a better thermal stability. It was found that the fill factor (FF) could be regulated by simply varying the block ratio of P3HT-b-P3PHT and played a crucial role in improving both the PCE and the thermal stability. The P3HT-b-P3PHT diffused at the P3HT:PC61BM interface, improved the miscibility between P3HT and PC61BM, optimized the nanoscale morphology of the photoactive layer, and reduced the active layer roughness, all of which improved the FF and thus contributed to an improvement in device performance.</P>

        Effects of Fermented Potato Pulp on Performance, Nutrient Digestibility, Carcass Traits and Plasma Parameters of Growing-finishing Pigs

        Li, P.F.,Xue, L.F.,Zhang, R.F.,Piao, Xiangshu,Zeng, Z.K.,Zhan, J.S. Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.10

        A total of 629 Duroc${\times}$Landrace${\times}$Large White crossbred pigs were utilized in three experiments (Exp. 1, 222 pigs weighing $25.6{\pm}2.0\;kg$ BW; Exp. 2, 216 pigs weighing 5$6.2{\pm}4.3\;kg$ BW; Exp. 3, 191 pigs weighing $86.4{\pm}4.6\;kg$ BW) conducted to determine the effects of fermented potato pulp on performance, nutrient digestibility, carcass traits and plasma parameters in growingfinishing pigs. Each experiment lasted 28 d. The pigs were assigned to one of two corn-soybean meal-based diets containing 0 or 5% fermented potato pulp. The inclusion of fermented potato pulp increased weight gain (p<0.05) in experiments 1 and 2 and increased feed intake (p<0.05) in experiment 2. Feed conversion was improved (p<0.05) in experiment 2 and showed a tendency to improve (p<0.10) in experiments 1 and 3 when pigs were fed fermented potato pulp. Fermented potato pulp increased (p<0.05) dry matter digestibility in experiments 1 and 3 and energy digestibility in experiment 2. Feeding fermented potato pulp decreased plasma urea nitrogen (p<0.05) and alanine aminotransferase (p<0.05) in experiments 1 and 2, while plasma aspartate aminotransferase was decreased (p<0.05) in experiment 3. Dietary fermented potato pulp did not affect the carcass characteristics of finishing pigs. Feeding fermented potato pulp reduced (p<0.05) fecal ammonia concentration in all three experiments. In conclusion, feeding growing-finishing pigs diets containing 5% fermented potato pulp improved weight gain and feed conversion without any detrimental effects on carcass traits. The improvements in pig performance appeared to be mediated by improvements in nutrient digestibility.

        Vitamin E improves antioxidant status but not lipid metabolism in laying hens fed a aged corn-containing diet

        Ding, X.M.,Mu, Y.D.,Zhang, K.Y.,Wang, J.P.,Bai, S.P.,Zeng, Q.F.,Peng, H.W. Asian Australasian Association of Animal Productio 2021 Animal Bioscience Vol.34 No.2

        Objective: The objective of this study was to determine whether a dietary vitamin E (VE) supplement could alleviate any detrimental effects of aged corn on lipid metabolism and antioxidant status in laying hens. Methods: The experiment consisted of a 2×3 factorial design with two corn types (normal corn and aged corn (stored for 4 yr) and three concentrations of VE (0, 20, and 100 IU/kg). A total of 216 Lohmann laying hens (50 wk of age) were randomly allocated into six treatment diets for 12 wk. Each treatment had 6 replicates of 6 hens per replicate. Results: The results show that aged corn significantly decreased the content of low-density lipoprotein cholesterol (p<0.05), and reduced chemokine-like receptor 1 (CMKLR1) mRNA expression (p<0.05) in the liver compared to controls. Diet with VE did not alter the content of crude fat and cholesterol (p>0.05), or acetyl-CoA carboxylase, lipoprotein lipase, fatty acid synthase or CMKLR1 mRNA expression (p>0.05) in the liver among treatment groups. Aged corn significantly increased the content of malondialdehyde (MDA) (p<0.05) and decreased superoxide dismutase (SOD) activity (p<0.05) in the liver. The VE increased the content of MDA (p<0.05) but decreased glutathione peroxidase (GSH-Px) activity in serum (p<0.01) and in the ovaries (p<0.05). Adding VE at 20 and 100 IU/kg significantly increased GSH-Px activity (p<0.05) in liver and in serum (p<0.01), 100 IU/kg VE significantly increased SOD activity (p<0.05) in serum. Aged corn had no significant effects on GSH-Px mRNA or SOD mRNA expression (p<0.01) in the liver and ovaries. Addition of 100 IU/kg VE could significantly increase SOD mRNA expression (p<0.01) in the liver and ovary. Conclusion: Aged corn affected lipid metabolism and decreased the antioxidant function of laying hens. Dietary VE supplementation was unable to counteract the negative effects of aged corn on lipid metabolism. However, addition of 100 IU/kg VE prevented aged corninduced lipid peroxidation in the organs of laying hens.

        Final overall survival analysis for the phase II RECORD-3 study of first-line everolimus followed by sunitinib versus first-line sunitinib followed by everolimus in metastatic RCC

        Knox, J. J.,Barrios, C. H.,Kim, T. M.,Cosgriff, T.,Srimuninnimit, V.,Pittman, K.,Sabbatini, R.,Rha, S. Y.,Flaig, T. W.,Page, R. D.,Beck, J. T.,Cheung, F.,Yadav, S.,Patel, P.,Geoffrois, L.,Niolat, J.,B Oxford University Press 2017 ANNALS OF ONCOLOGY Vol.28 No.6

        <P><B>Background</B></P><P>RECORD-3 compared everolimus and sunitinib as first-line therapy, and the sequence of everolimus followed by sunitinib at progression compared with the opposite (standard) sequence in patients with metastatic renal cell carcinoma (mRCC). This final overall survival (OS) analysis evaluated mature data for secondary end points.</P><P><B>Patients and methods</B></P><P>Patients received either first-line everolimus followed by second-line sunitinib at progression (<I>n = </I>238) or first-line sunitinib followed by second-line everolimus (<I>n = </I>233).

The impacts of neutrophil lymphocyte ratio (NLR) and baseline levels of soluble biomarkers on OS were explored.</P><P><B>Results</B></P><P>At final analysis, median duration of exposure was 5.6 months for everolimus and 8.3 months for sunitinib. Median combined PFS was 21.7 months [95% confidence interval (CI) 15.1–26.7] with everolimus-sunitinib and 22.2 months (95% CI 16.0–29.8) with sunitinib-everolimus [hazard ratio (HR)<SUB>EVE-SUN/SUN-EVE</SUB>, 1.2; 95% CI 0.9–1.6]. Median OS was 22.4 months (95% CI 18.6–33.3) for everolimus-sunitinib and 29.5 months (95% CI 22.8–33.1) for sunitinib-everolimus (HR<SUB>EVE-SUN/SUN-EVE</SUB>, 1.1; 95% CI 0.9–1.4). The rates of grade 3 and 4 adverse events suspected to be related to second-line therapy were 47% with everolimus and 57% with sunitinib.

        Factors Affecting Reproductive Performance in the Nepalese Pakhribas Pig: Effects of Nutrition and Housing during Lactation

        Shrestha, N.P.,Edwards, S.A.,English, P.R.,Robertson, J.F. Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.5

        The effects of housing and nutrition on the performance of first lactation sows of the Nepalese Pakhribas breed were investigated. A total of 36 sows, from a previous experiment on nutrition during gilt rearing, were allocated according to a factorial design with 2 levels of nutrition, 60 or 80% of the calculated lactation requirement, and two types of housing, traditional or improved. The mean live weight loss of sows during lactation was reduced to a slightly greater extent by improved housing (p<0.05) than by better nutrition (p<0.10). There was also a significantly lower loss of $P_2$ backfat thickness (p<0.05) and mean body condition score (p<0.05) for sows on the higher plane of nutrition. Piglet weight gain in early and mid lactation was influenced by gestation feeding of the gilt (p<0.10) and by housing (p<0.05). Late lactation gain was influenced only by lactation feeding (p<0.05). In consequence, piglet weight at 42 day weaning was increased to a similar extent by improved housing (p<0.05) and better lactation nutrition (p<0.01). Significantly more sows were remated by day 10 after weaning from a higher level of rearing nutrition ($x^2=13.57$, p=0.001), and from improved housing and improved lactation (both $x^2=4.57$, p=0.033). It is concluded that, under Nepalese village conditions, improvements in housing may be a more cost effective way of improving sow performance than expenditure on additional feed resources.

      • Promoter methylation of the Wnt/β‐catenin signaling antagonist <i>Dkk‐3</i> is associated with poor survival in gastric cancer

        Yu, Jun,Tao, Qian,Cheng, Yuen Y.,Lee, Kwan Y.,Ng, Simon S. M.,Cheung, Kin F.,Tian, Linwei,Rha, Sun Y.,Neumann, Ulf,,cken, Christoph,Ebert, Matthias P. A.,Chan, Francis K. L.,Sung, Joseph J. Y. Wiley Subscription Services, Inc., A Wiley Company 2009 Cancer Vol.115 No.1

        <P><B>Abstract</B></P><P><B>BACKGROUND:</B></P><P>Abnormal activation of the Wnt/β‐catenin signaling pathway is common and critical in the pathogenesis of digestive cancers. In this study, the authors investigated the promoter methylation of the dickkopf homolog 3 gene <I>Dkk‐3</I> in these cancers and its prognostic significance in gastric cancer.</P><P><B>METHODS:</B></P><P><I>Dkk‐3</I> methylation was assessed in 173 patients with gastric cancers (including 104 patients who were followed for up to 4090 days) and in 128 patients with colorectal cancer. Cell growth was evaluated by using a colony‐formation assay. For survival analyses, the authors used Kaplan‐Meier plots, the log‐rank test, and Cox proportional regression.</P><P><B>RESULTS:</B></P><P><I>Dkk‐3</I> was silenced or down‐regulated in 12 of 17 gastric cancer cell lines (70.6%) and in 3 of 9 colon cancer cell lines (33.3%). The loss of gene expression was associated with promoter methylation, which could be restored by demethylating agents. Ectopic expression of <I>Dkk‐3</I> suppressed colony formation. Moreover, methylation of <I>Dkk‐3</I> was detected in 117 of 173 primary gastric tumors (67.6%) and in 67 of 128 colorectal tumors (52.3%). The clinical significance and the prognostic value of <I>Dkk‐3</I> methylation also were examined in 104 gastric cancers and in 84 colorectal cancers. Multivariate analysis indicated that <I>Dkk‐3</I> methylation was associated significantly and independently with poor disease survival (relative risk, 2.534; 95% confidence interval, 1.54–4.17; <I>P</I> = .002) in gastric cancer, but not in colorectal cancer. Kaplan‐Meier survival curves revealed that patients who had <I>Dkk‐3</I> methylated gastric cancers had a significantly shorter survival (median, 0.76 years) compared with patients who did not have <I>Dkk‐3</I> methylation (median, 2.68 years; <I>P</I> < .0001; log‐rank test).</P><P><B>CONCLUSIONS:</B></P><P>Epigenetic silencing of the <I>Dkk‐3</I> gene by promoter methylation was a common event in gastric cancer and was associated with a poor outcome in such patients.

      • Autoantibodies and neuropsychiatric events at the time of systemic lupus erythematosus diagnosis: Results from an international inception cohort study

        Hanly, J. G.,Urowitz, M. B.,Siannis, F.,Farewell, V.,Gordon, C.,Bae, S. C.,Isenberg, D.,Dooley, M. A.,Clarke, A.,Bernatsky, S.,Gladman, D.,Fortin, P. R.,Manzi, S.,Steinsson, K.,Bruce, I. N.,Ginzler, E Wiley Subscription Services, Inc., A Wiley Company 2008 Vol.58 No.3

        <B>Objective</B><P>To examine, in an inception cohort of systemic lupus erythematosus (SLE) patients, the association between neuropsychiatric (NP) events and anti–ribosomal P (anti-P), antiphospholipid (lupus anticoagulant [LAC], anticardiolipin), anti–β2-glycoprotein I, and anti–NR2 glutamate receptor antibodies.</P><B>Methods</B><P>NP events were identified using the American College of Rheumatology case definitions and clustered into central/peripheral and diffuse/focal events. Attribution of NP events to SLE was determined using decision rules of differing stringency. Autoantibodies were measured without knowledge of NP events or their attribution.</P><B>Results</B><P>Four hundred twelve patients were studied (87.4% female; mean ± SD age 34.9 ± 13.5 years, mean ± SD disease duration 5.0 ± 4.2 months). There were 214 NP events in 133 patients (32.3%). The proportion of NP events attributed to SLE varied from 15% to 36%. There was no association between autoantibodies and NP events overall. However, the frequency of anti-P antibodies in patients with central NP events attributed to SLE was 4 of 20 (20%), versus 3 of 107 (2.8%) in patients with other NP events and 24 of 279 (8.6%) in those with no NP events (P = 0.04). Among patients with diffuse NP events, 3 of 11 had anti-P antibodies (27%), compared with 4 of 111 patients with other NP events (3.6%) and 24 of 279 of those with no NP events (8.6%) (P = 0.02). Specific clinical–serologic associations were found between anti-P and psychosis attributed to SLE (P = 0.02) and between LAC and cerebrovascular disease attributed to SLE (P = 0.038). There was no significant association between other autoantibodies and NP events.</P><B>Conclusion</B><P>Clinically distinct NP events attributed to SLE and occurring around the time of diagnosis were found to be associated with anti-P antibodies and LAC. This suggests that there are different autoimmune pathogenetic mechanisms, although low sensitivity limits the clinical application of testing for these antibodies.</P>
