To assess trueness of IM, MIL, and stereolithog. printed denture bases after manufacturing, hydrothermal cycling, and microwave sterilization. 16 Edentulous maxillary plaster models were poured using silicone mold and digitized by means of desktop scanner. For group IM, 16 denture bases were injection molded. MIL and SLA, denture bases were virtually designed and manufactured referring to digitized data. A total of 48 samples were scanned 1) after manufacturing, 2) after hydrothermal cycling three as well as 4) six cycles of microwave sterilization for 6 min each at 640 W. The 3D surface deviation of the total intaglio surface, the palate, the alveolar ridge, and the border seal region was evaluated on basis of RMSE and pos. and neg. mean deviations with inspection software. In comparison, IM showed increased, mainly pos., deviations at border seal. SLA presented highest total RMSE with increased neg. deviations, likewise at the border seal. In contrast to SLA, no differences between IM and MIL were measured after hydrothermal cycling. Following microwave sterilization, the trueness of SLA was higher compared to IM and MIL with no differences between MIL and IM. Distortion of IM and MIL was measured after the 3rd cycle with no further changes observed Subtractive manufacturing of denture bases results in the highest trueness, followed by IM and SLA. IM and SLA, hydrothermal cycling did not affect MIL. SLA printed denture bases remained dimensionally stable after microwave sterilization.

Wong, Man Shing; Li, Zhong Hui; Tao, Ye; D’Iorio, Marie published the artcile< Synthesis and Functional Properties of Donor-Acceptor π-Conjugated Oligomers>, Product Details of C19H34O2, the main research area is function property donor acceptor pi conjugation oligomer synthesis.

Novel donor-acceptor oligophenylenevinylenes (OPVs) bearing an electron-donating 2-(2-butoxyethoxy)ethoxy group at one end and various electron-withdrawing groups including alkylsulfonyl, cyano, and nitro functionalities at the other end have been synthesized for investigation of structure-functional property relationships. Depending on the nature of the electron-withdrawing group, the newly synthesized donor-acceptor OPVs can exhibit an efficient light-emitting property or a large photovoltaic effect. The asym. disubstituted OPV bearing 2-(2-butoxy-ethoxy)ethoxy-hexylsulfonyl functionalities possesses superior mol. properties for light-emitting applications than the sym. 2-(2-butoxyethoxy)ethoxy-disubstituted counterparts. In addition, our first observation and investigation on the photovoltaic response in polyalkyleneoxy-nitro disubstituted OPV series is reported. The spectral response of the photovoltaic device corresponds to the absorption characteristics of the oligomer. Most importantly, the photocurrent response increases with an extension of the conjugated length of the oligomer.

Abstract: Extracellular vesicle (EV)-mediated transfer of long non-coding RNAs (lncRNAs) has been reported to regulate chemoresistance in various cancers. We herein investigate the therapeutic potential of bioinformatically identified HOTAIR transferred by serum-derived EVs (serum-EVs) in temozolomide (TMZ) resistance of glioblastoma (GBM) and the downstream mechanisms. EVs were isolated from the serum of GBM patients. Expression of HOTAIR was examined in the clin. tissue samples and serum-EVs of GBM patients. The downstream miRNAs of HOTAIR and its target genes were predicted in silico. The effects of the HOTAIR transmitted by serum-EVs in malignant phenotypes, tumor growth, and TMZ resistance were assessed in vitro and in vivo. HOTAIR expression was upregulated in clin. tissues, cells, and serum-EVs of GBM. Co-culture data showed that GBM-serum-EVs facilitated GBM cell proliferative and invasive phenotypes and TMZ resistance by elevating HOTAIR. In GBM cells, HOTAIR competitively bound to miR-526b-3p and weakened miR-526b-3p′s binding ability to EVA1, thus increasing the expression of EVA1. Furthermore, HOTAIR carried by serum-EVs promoted tumor growth and TMZ resistance in vivo by suppressing miR-526b-3p-mediated EVA1 inhibition. GBM-serum-EV-enclosed HOTAIR may augment GBM progression and chemoresistance through miR-526b-3p downregulation and EVA1 upregulation. These results provide a strategy to reduce TMZ resistance in GBM treatment.

Kelderman, E.; Starmans, W. A. J.; van Duynhoven, J. P. M.; Verboom, W.; Engbersen, J. F. J.; Reinhoudt, D. N.; Derhaeg, L.; Verbiest, T.; Clays, K.; Persoons, A. published the artcile< Triphenylcarbinol Derivatives as Molecules for Second-Order Nonlinear Optics>, Reference of 112-63-0, the main research area is triarylcarbinol second order nonlinear optic; hyperpolarizability triarylcarbinol derivative; dipole moment triarylcarbinol derivative.

Novel tris D-π-A substituted triphenylcarbinol derivatives have been synthesized and studied for their mol. second-order nonlinear optical properties by elec. field induced second harmonic generation and hyper Rayleigh scattering (HRS). Compared to their Ph analogs with only one D-π-A system, the triphenylcarbinol derivatives I (R = NO2, R1 = H; R = CHO, R1 = Me) and II (R = CN, NO2) exhibit an increased hyperpolarizability (〈β〉HRS) without the undesired red-shift of the charge-transfer band. The dipole moments and hyperpolarizabilities depend on both the close proximity (3-4 Å) and the orientation of the three NLO-phore units. The nature of the acceptor substituent strongly influences the magnitude of the 〈β〉HRS values. I (R = NO2, R1 = H) exhibits a 〈β〉HRS value of 15 × 10-31 esu, which is almost the same as that of its reference compound, p-nitroanisole, whereas II (R = NO2) exhibits a 〈β〉HRS value of 338 × 10-30 esu, which is >3 times larger than that of its reference compound, 4-methoxy-4′-nitrostilbene.

Ye, Tingting; Chen, Rongrong; Zhou, Yu; Zhang, Juan; Zhang, Zhongqin; Wei, Hui; Xu, Yan; Wang, Yulan; Zhang, Yinlan published the artcile< Salvianolic acid A (Sal A) suppresses malignant progression of glioma and enhances temozolomide (TMZ) sensitivity via repressing transgelin-2 (TAGLN2) mediated phosphatidylinositol-3-kinase (PI3K) / protein kinase B (Akt) pathway>, Electric Literature of 112-63-0, the main research area is salvianolic acid temozolomide anticancer agent TAGLN2 PI3K Akt glioma; Glioma; Salvianolic acid A; TAGLN2/PI3K/akt pathway; Temozolomide.

Glioma originated from excessively proliferative and highly invaded glial cells is a common intracranial malignant tumor with poor prognosis. Resistance to temozolomide (TMZ) is a clin. challenge in glioma treatment due to the fact that chemoresistance remains a main obstacle in the improvement of drug efficacy. Salvianolic acid A (Sal A), originated from traditional Chinese herbal medicine Salvia miltiorrhiza, possesses anti-tumor effects and could facilitate the delivery of drugs to brain tumor tissues. In the present work, effects of Sal A on the viability, proliferation, migration, invasion and apoptosis of human glioma cell line U87 cells as well as influence of Sal A on TMZ resistance were measured, so as to identify the biol. function of Sal A in the malignant behaviors and chemoresistance of glioma cells. Addnl., activation of TAGLN2/PI3K/Akt pathway in glioma cells was also detected to investigate whether Sal A could regulate TAGLN2/PI3K/Akt to manipulate the progression of glioma and TMZ resistance. Results discovered that Sal A treatment reduced the viability, repressed the proliferation, migration and invasion of glioma cells as well as promoted the apoptosis of glioma cells. Besides, Sal A treatment suppressed TAGLN2/PI3K/Akt pathway in glioma cells. Sal A treatment strengthened the suppressing effect of TMZ on glioma cell proliferation and reinforced the promoting effect of TMZ on glioma cell apoptosis, which were abolished by upregulation of TAGLN2. To conclude, Sal A treatment could suppress the malignant behaviors of glioma cells and improve TMZ sensitivity through inactivating TAGLN2/PI3K/Akt pathway.
