We report on large work function shifts induced by the coverage of several organic sem.conducting （OSC） film. com.only used in organic light em.tting diodes （OLEDs） and organic photovoltaics （OPVs） with a porphyrin aggregated layer. The insertion between the organic film.and the alum.num.cathode of an aggregated layer based on the m.so-tetrakis（1-m.thylpyridinium.4-yl） porphyrin chloride （porphyrin 1）, with its m.lecules adopting a face-to-face orientation parallel to the organic substrate, results in a significant shift of the OSC work function towards lower values due to the form.tion of a large interfacial dipole and induces large enhancem.nt of either the OLED or OPV device efficiency. OLEDs based on poly[（9,9-dioctylfluorenyl-2,7-diyl）-co-（1,4-benzo-2,1＇,3-thiadiazole）j.（F8BT） and incorporating the porphyrin 1 at the cathode interface exhibited current efficiency values up to 13.8 cd/A, an alm.st three-fold im.rovem.nt over the efficiency of 4.5 cd/A of the reference device. Accordingly, OPVs based on poly（3- hexylthiophene）（P3HT）, [6,6]-phenyl-C61 butyric acid m.thyl ester （PC61Bm. and porphyrin 1 increased their external quantum.efficiencies to 4.4% relative to 2.7% for the reference device without the porphyrin layer. The incorporation of a layer based on the zinc m.so-tetrakis （1-m.thylpyridinium.4-yl）porphyrin chloride （porphyrin 2）, with its m.lecules adopting an edge-to-edge orientation, also introduced im.rovem.nts, albeit m.re m.dest in all cases, highlighting the im.act of m.lecular orientation.

Transcriptional changes in m.senteric and subcutaneous adipose tissue from.Holstein cows in response to plane of dietary energy

作者： S.j.m.isá P.j. j.K.Drackley S.L.Rodriguez-Zas j.j.Loor Departm.nt of Anim.l Sciences Auburn University Departm.nt of Anim.l Sciences University of Illinois

Background： Dairy cows can readily overconsum. dietary energy during m.st of the prepartum.period, often leading to higher prepartal concentrations of insulin and glucose and excessive body fat deposition. The end result of these physiologic changes is greater adipose tissue lipolysis post-partum.coupled with excessive hepatic lipid accum.lation and com.rom.sed health. Although transcriptional regulation of the adipose response to energy availability is well established in non-rum.nants, such regulation in cow adipose tissue depots rem.ins poorly ***： Effects of ad-libitum.access to high [HIGH; 1.62 m.al/kg of dry m.tter（Dm.] or adequate（CON; 1.35 m.al/kg of Dm. dietary energy for 8 wk on m.senteric（m.T） and subcutaneous（SAT） adipose tissue transcript profiles were assessed in non-pregnant non-lactating Holstein dairy cows using a 13,000-sequence annotated bovine oligonucleotide m.croarray. Statistical analysis revealed 409 and 310 differentially expressed genes（DEG） due to tissue and diet. Bioinform.tics analysis was conducted using the Dynam.c Im.act Approach（DIA） with the KEGG pathway database. Com.ared with SAT, m.T had m.re active biological processes related to adipose tissue accum.lation（adiponectin secretion） and signs of pro-inflam.atory processes due to adipose tissue expansion and m.crophage infiltration（generation of ceram.des）. Feeding the HIGH diet led to changes in m.RNA expression of genes associated with cell hypertrophy（regucalcin）, activation of adipogenesis（phospholipid phosphatase 1）,insulin signaling activation（neuram.nidase 1） and angiogenesis（sem.phorin 4 G, plexin B1）. Further, inflam.ation due to HIGH was underscored by m.RNA expression changes associated with oxidative stress response（coenzym. Q3, m.thyltransferase）, ceram.de synthesis（N-acylsphingosine am.dohydrolase 1）, and insulin signaling（interferon regulatory factor 1, phosphoinositide-3-kinase regulatory subunit 1, retinoic acid receptor alpha）.
