Wu, Yehui published the artcileLow-cost and efficient hole transport materials based on 9-phenyl-9H-carbazole branch for perovskite solar cells, Name: 9-(4-Fluorophenyl)-9H-carbazole, the publication is Surfaces and Interfaces (2022), 101598, database is CAplus.

Hole transport materials (HTMs) play a pivotal role in the hole extraction and transportation processes in perovskite solar cells (PSCs). Although a great number of HTMs based on various planar conjugated cores have been explored, the development of branches is rather limited. In this work, branches of 9-phenyl-9H-carbazole derivatives have been incorporated in different N-alkylated dithieno[3,2-b:2�3�d]pyrrol (DTP) core to construct HTMs (TM-9 to TM-14). Among them, TM-13 with 9-(4-methoxyphenyl)-9H-carbazole branch exhibites excellent performance in hole extraction and transportation ability. Consequently, the PSCs based on TM-13 have achieved the power conversion efficiency (PCE) of 20.44%, which is comparable to the PCE of 20.62% with the widely used Spiro-OMeTAD HTM. More importantly, the synthetic cost of TM-13 (62 dollar/g) is much lower than that of Spiro-OMeTAD (400 dollar/g), suggesting its promising commercialization for low-cost and efficient HTMs for PSCs.

Zhou, Xiao-dao published the artcileInfluence of parecoxib Na on anesthesia recovery period of patients under the fast track anesthesia with remifentanil, Product Details of C19H17N2NaO4S, the publication is Zhongguo Linchuang Yaolixue Zazhi (2015), 31(9), 708-711, database is CAplus.

Objective To investigate the effects of preoperative use of parecoxib Na during anesthesia recovery period on the fast track anesthesia with remifentanil. Methods A total of 105 cases who received laparoscopic cholecystectomy were randomly divided into three groups with 35 cases in each group. Patients in group A received parecoxib Na 40 mg dissolved in normal saline 10 mL through injection 20 min before induction of anesthesia. Patients in group B received parecoxib Na 40 mg dissolved in normal saline10 mL through injection 20 min before the end of surgery. Patients in group C received normal saline 10 mL through injection 20 min before induction of anesthesia. The data of mean arterial pressure (MAP), heart rate (HR) and oxygen saturation (SPO₂), verbal rating scale (VRS), sedation-agitation scale (SAS), Ramsay sedation scale (RSS) and comfort score (BCS) were compared among three groups. Results The data of MAP, SAS and HR in group A and group B were significantly lower than those in group C, and the data of MAP, SAS and HR in group A were significantly lower than those in group B (P<0.05). The data of RSS in group A was significantly lower than that in group B and RSS in group A and group B significantly higher than those in group C from T₂ to T₄ (P<0.05). The data of VRS in group A and group B were significantly lower than those in group C, and that in group A was significantly lower than group B each time point (P<0.05). Postoperative BCS in group A and group B were significantly higher than those in group C, and that in group A was significantly higher than group B (P<0.05). Conclusion Preoperative use of parecoxib Na could significantly reduce the acute pain of the fast track anesthesia with remifentanil, effectively inhibiting hyperalgesia and reducing the patient’s agitation.

Wu, Xiulan published the artcileFace-to-face order-packed mode promotes thermally activated delayed fluorescence to achieve stronger aggregation-induced emission, HPLC of Formula: 57103-14-7, the publication is Journal of Science: Advanced Materials and Devices (2022), 7(2), 100432, database is CAplus.

Two novel aggregation-induced delayed fluorescence materials (AIDF) FCP-BP-PXZ [9- (4-Fluorophenyl) -9H-carbazole-3-yl] [4- (10H-phenoxazine-10-yl) phenyl] methane and FCP-BP-PTZ [9- (4-Fluorophenyl) -9H-carbazole-3-yl] [4- (10H-penzothiazin-10-yl) phenyl] methane were synthesized. Experiments and mol. dynamics (MD) simulations revealed that FCP-BP-PXZ exhibits orderly face-to-face arrangement stacking mode, which inhibits non-radiation inactivation channel and reduces energy loss by restricting larger vibration and rotation of the mol. due to abundant intermol. hydrogen bonds and strong intermol. π-π interactions. FCP-BP-PTZ′s performance was hampered by erratic relaxation aggregation. The maximal external quantum efficiency (EQE_max) of non-doped and doped organic light-emitting diodes (OLEDs) constructed on FCP-BP-PXZ was 11.2% and 18.2%, resp. Furthermore, at a brightness of 1000 cd m^-2, non-doped and doped devices had a low turn-on voltage of 3.0-3.5 V, with 2.0% and 3.3% efficiency roll-off, owing to the microsecond-scale delayed lifetime. The FCP-BP-PXZ-based non-doped device, in particular, achieved a brightness of 62,390 cd m^-2, which was crucial in non-doped yellow OLEDs.

Objective To investigate the effect of paricoxib sodium on postoperative cognitive dysfunction (POCD) in elderly depression rats. Methods The total of 36 elderly male Sprague Dawley (SD) rats were divided into 3 groups: normal control group (n = 6); surgical group (Sur group, n = 15); paricoxib sodium group (Pare group, n = 15). Depression models were established in rats except those in the normal control group.

Behavior and cognition of all animals were evaluated by open-field, sucrose consumption and Morris water maze tests. IL-6 and IL-1β expression were detected by Elisa. Results The escape latency was (39.98±8.93) s in Pare group vs (47.15±10.87) s in Sur group (P<0.05); and the space exploration was (24.17±8.52) s vs (20.96±9.58) s (P<0.05). IL-6 expression was (72.86±6.82) in Pare group vs (79.26±4.19) ng·L^-1 in Sur group, IL-1β expression was (350.73±28.04) vs (423.35±26.81) ng·L^-1 (P<0.05). The horizontal and vertical scores were significantly higher in Pare group than those in the Sur group (P<0.05). The sucrose consumption and sucrose preference were higher and the water consumption was lower in Pare group than those in the Sur group (P<0.05). Conclusion Parecoxib sodium may improve postoperative cognition of elderly rats with depression, which being associated with decrease of IL-6 and IL-1β expression in hippocampus.

Serebryannikova, Anna V. published the artcileSynthesis of Isoxazole- and Oxazole-4-carboxylic Acids Derivatives by Controlled Isoxazole-Azirine-Isoxazole/Oxazole Isomerization, SDS of cas: 1076-59-1, the publication is Journal of Organic Chemistry (2019), 84(23), 15567-15577, database is CAplus and MEDLINE.

The first synthesis of isoxazole-4-carboxylic acid derivatives by domino isoxazole-isoxazole isomerization is reported. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxy-/5-aminoisoxazoles (dioxane, 105°) leads to the formation of isoxazole-4-carboxylic esters and amides in good yields. 4-Formyl-5-methoxyisoxazoles give Me oxazole-4-carboxylates under the same reaction conditions. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxyisoxazoles under milder conditions (MeCN, 50°) allows the preparation of transient 2-acyl-2-(methoxycarbonyl)-2H-azirines. The azirines isomerize quant. either into isoxazoles under catalytic conditions (dioxane, 105°) or into oxazoles under noncatalytic thermolysis (o-dichlorobenzene, 170°). The mechanism of the isomerization and dependence of the reaction routes on substituents at starting isoxazole core and reaction conditions are discussed on the basis of DFT calculations
