We demonstrate highly efficient multi-colored semitransparent perovskite solar cells that can create high angular tolerant controllable transmissive colors up to 60~, based on phase-compensated microcavities. The efficiency of the semitransparent colors was improved by impedance matching, which was enabled by placing a dielectric functional layer on top of traditional optical microcavities, with negligible influence on color pureness. The vast majority of the visible part of solar radiation is efficiently utilized for solar energy harvesting, achieving 10.47%, 10.66%, and 11.18% of efficiency for red, green, and blue （RGB） colored solar cells, respective136 while a very small proportion of the visible solar spectrum is used for structural coloration that can be readily tuned by altering the cavity medium thickness. The approach described herein can be suitable for a variety of applications such as display systems with ultra-low power consumption, highly efficient colorful solar panels, low-power wearable electronics, and energy-efficient optoelectronics.

AIM： To assess the ability of endoscopic ultrasonography （EUS） to differentiate neoplastic from non- neoplastic polypoid lesions of the gallbladder （PLGs）.METHODS： The uses of EUS and transabdominal ultrasonography （US） were retrospectively analyzed in 94 surgical cases of gallbladder polyps less than 20 mm in ***： The prevalence of neoplastic lesions with a diameter of 5-20 mm was 27.2% （10/58）; 22-15 mm, 25.4% （4/26）, and 16-20 mm, 50% （5/20）. The overall diagnostic accuracies of EUS and US for small PLGs were 80.9% and 63.9% （P 〈 0.05）, respectively. EUS correctly distinguished 12 （63.2%） of 19 neoplastic PLGs but was less accurate for polyps less than 1.0 cm （4/10, 40%） than for polyps greater than 1.0 cm （8/9, 88.9%）（P = 0.02）.CONCLUSION： Although EUS was more accurate than US, its accuracy for differentiating neoplastic from non-neoplastic PLGs less than 1.0 cm was low. Thus, EUS alone is not sufficient for determining a treatment strategy for PLGs of less than 1.0 cm.

Although alpha-synuclein is generally thought to have a pathological role in Parkinson＇s disease, accumulative evidence exists that alpha-synuclein has a neuroprotective effect. The aim of this study was to evaluate the effect of extracellular alpha-synuclein on dopaminergic cell survival. We assessed cell viability using the 3-（4,5-dimethyt-thiazol-2-yt）-2,5-diphenyltertazolium bromide （MTT） assay both in undifferentiated SH-SY5Y （SHSY） cells and neuronally-differentiated SH-SY5Y （ndSHSY） cells after 24 hour treatment with monomeric alpha-synuclein at various concentrations （0 [control], 50, 100 nmol/L, 1 IJmol/L）. To determine whether cell viability assessed by MTT assay was affected by cell proliferation, 5-bromo-2＇-deoxyuridine （BrdU） incorporation assay was per- formed. Level of both Akt and phosphorylated Akt was measured using western blot method in ndSHSY cells with or without 24 hour alpha-synuclein treatment. Cell viability was increased in ndSHSY cells at the nanomolar concentration of alpha-synuclein, but not in SHSY cells. Proportion of BrdU-positive ndSHSY cells was decreased in alpha-synuclein-treated group compared with control group. Level of phosphorylated Akt in alpha-synuclein-treated group was higher compared with the control group. Our study shows that extracellular alpha-synuclein at nanomolar concentra- tion benefits dopaminergic cell survival via Akt pathway.

Background: The optimal treatment strategy for biliary tract cancer(BTC) after curative?intent resection remains con?troversial. The purpose of this study was to evaluate the efficacy of fluoropyrimidine?based adjuvant chemotherapy for BTC patients undergoing microscopically margin?negative(R0) ***: We retrospectively analyzed the clinical data of BTC patients who underwent curative?intent R0 resection. Patients were eligible if they received either fluoropyrimidine?based adjuvant chemotherapy or observation after R0 ***: A total of 153 patients were included. In the entire patient cohort, no significant differences were observed in 5?year overall survival(OS) rates(48.4% vs. 39.6%, P = 0.439) or 3?year recurrence?free survival(RFS) rates(49.1% vs. 39.5%, P = 0.299) between patients who received fluoropyrimidine?based adjuvant chemotherapy or observation. However, for patients with stages Ⅱ and Ⅲ BTC, chemotherapy significantly improved 5?year OS rate(52.4% vs. 35.6%, P = 0.002) and 3?year RFS rate(55.5% vs. 39.1%, P = 0.021) compared with ***: Fluoropyrimidine?based adjuvant chemotherapy may prolong the survival of patients with stages Ⅱ and Ⅲ BTC after R0 resection.

Homogeneous co-precipitation and hydrothermal treatment were used to prepare nano- and highly dispersed Ni O/YSZ(yttria-stabilized zirconia) composite powders. Composite powders of size less than 100 nm were successfully prepared. This process did not require separate sintering of the YSZ and Ni O to be used as the raw materials for solid oxide fuel cells. The performance of a cell fabricated using the new powders(*** density ~0.87 W/cm^2) was higher than that of a cell fabricated using conventional powders(max. power density ~0.73 W/cm^2). Co-precipitation and hydrothermal treatment proved to be very effective processes for reducing cell production costs as well as improving cell performance.
