The electron extraction of inverted polymer solar cells (PSCs) was enhanced by modifying surface energy buffer layer. We introduced organic–inorganic hybrid ZnO–PFN interlayer as
In this study, a highly soluble poly[quinacridone-alt-quinoxaline] series (PQCQx, PQCTQx, PQCTPz) was synthesized through the Suzuki coupling reaction by introducing planar quinacridone and quinoxaline. The polymers were in general organic solvents, Mn 15.6–85.0 kg mol−1. optical band gap energy 1.82–1.97 eV, which similar to of benzothiadiazole derivative. HOMO LUMO levels −5.32 −5.46 eV −3.40 3.50 respectively. According XRD measurements, PQCQx PQCTPz showed formation an ordered lamellar...
Highly soluble poly[quinacridone-alt-benzothiadiazole] (PQCDTB) has been synthesized through the Suzuki coupling reaction by introducing planar quinacridone and highly absorbing benzothiadiazole. The PQCDTB dissolved in general organic solvents, Mn was 49.8 kg/mol. optical band gap energy 1.92 eV, which similar to of HOMO LUMO levels were −5.24 eV −3.32 respectively. According XRD measurement, showed formation ordered lamellar structure as an out-of-plane peak (h00) alkyl side chain...
Bisphenol A diglycidyl ether (BADGE) is commonly used to stabilize products synthesized from epichlorohydrin and bisphenol A. Although recent studies suggest that BADGE may adversely affect the male reproductive system, its underlying mechanisms remain unclear. This study investigates impact of exposure on steroidogenesis via DNA methylation changes in adult zebrafish gonads. Adult were exposed (10 μM) for 21 days (n = 15 per group). Genomic mRNA extracted testes. Whole-genome bisulfite...

Purpose Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare group of with a wide spectrum clinical behavior. However, there no known clinically relevant biomarkers to predict metastasis. Experimental Design To investigate differential gene expression signatures metastatic vs non-metastatic NETs, we studied cell cycle regulatory genes in 19 and 22 colorectal NETs by PCR arrays. Immunohistochemistry (IHC) quantitative real-time RT-PCR were performed verify the results another set...
Organic–inorganic hybrid solar cells were fabricated with InP QDs (5 wt%) in a BHJ active layer (PTB7 + PC<sub>71</sub>BM).
Cesium lead bromide (CsPbBr3), an inorganic perovskite material with a large band gap energy (Eg = 2.3 eV), is great candidate to produce stable and semitransparent solar cell (PSC) platforms owing its complete structure in humid environments. We synthesized quantum dots (QDs) composed of five atoms, copper (Cu), zinc (Zn), indium (In), sulfur (S), selenium (Se; CZISSe QDs), incorporated them into CsPbBr3 films. To enable the dispersion CsPbBr3-capped QDs PbBr2 solution, we used...

Recently, has been shown to be crucial the expression activation KIT oncoprotein. The aim was explore role as a prognostic marker therapeutic target (GISTs) other tumours. Methods results: evaluated by...
To evaluate whether promoter methylation is related to responsiveness for chemotherapy or clinical outcome, we performed an association analysis between and outcomes. Patients with nodal diffuse large B‐cell lymphomas (DLBCL) at a single institute (n=44) were studied of tumor‐related genes, MGMT, p15 INK4B , p16 INK4A Mad2, TMS1/ASC, CASP8 GSTP1 . The behavior DLBCL after was followed up analyzed. Hypermethylation promoters Mad2 TMS1/ASC genes observed in 52.3%, 31.8%, 54.5%, 47.7%, 50%,...
Four cases of very rare composite glandular‐endocrine cell carcinoma the stomach are presented with methylation findings. All but one tumors arose in antrum and two them were at early stage. Each was accompanied by atrophic metaplastic gastritis adjacent mucosa. Three showed lymph nodes metastasis, both glandular neuroendocrine tumor components within metastatic nodes. Mucin stains positive adenocarcinoma areas while only markers components. Of all seven tested for, p16INK4A observed hMLH1...
In this study, we synthesized three conjugated polymer electrolytes (CPEs) with different conjugation lengths to control their dipole moments by varying spacers. P-type CPEs (PFT-D, PFtT-D, and PFbT-D) were generated the facile oxidation of n-type (PFT, PFtT, PFbT) introduced as hole-transporting layers (HTLs) organic solar cells (OSCs) light-emitting diodes (PLEDs). To identify effect on electrode work function tunability changing molecular conformation arrangement, simulated density...
Background/Aim: Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a very rare type of tumor, comprising these two different components in single mass. Although several studies have determined the genetic characteristics cHCC-CC, next-generation sequencing (NGS) data for comparing clonality cHCC-CC are currently unavailable. Materials and Methods: Four cases were selected HCC, CC normal from each case separately micro-dissected. DNA RNA isolated sample sequenced by Oncomine...
In this study, we fabricated conventional structured organic solar cells (OSCs) by introducing a hole extraction layer (HEL) that consisted of poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT:PSS) and conjugated polymer electrolyte (CPE) poly[9,9-bis(4'-sulfonatobutyl)fluorene-alt-thiophene] (PFT-D). PFT-D has -SO3- functional group acts as conjugate base against the -SO3H PSS. addition, molecular dipole can screen Coulombic attraction between PEDOT chains PSS chains. By blending...
