Long Non-coding RNA PCED1B Antisense RNA 1 Promotes Cell Proliferation and Invasion in Hepatocellular Carcinoma by Regulating the MicroRNA-34a/CD44 Axis.

Objective: This study aimed to examine the role of long non-coding RNA PCED1B antisense RNA 1 (PCED1B-AS1) in the development of hepatocellular carcinoma (HCC).

Methods: A total of 62 pairs of HCC tissues and adjacent non-tumor tissues were obtained from 62 HCC patients. The interactions of PCED1B-AS1 and microRNA-34a (miR-34a) were detected by dual luciferase activity assay and RNA pull-down assay.

Bicyclopentadithiophene-Based Organic Semiconductor for Stable and High-Performance Perovskite Solar Cells Exceeding 22.

Well-performing organic-inorganic halide perovskites are susceptible to poor efficiency and instability due to their various defects at the interphases, grain boundaries (GBs), and surfaces. In this study, an in situ method is utilized for effectively passivating the under-coordinated Pb defects of perovskite with new non-fullerene acceptors (NFAs) (; X = H, Cl, and Br) through their carbonyl and cyano functional groups during the antisolvent dripping process. It reveals that the bicyclopentadithiophene (BCDT) core with highly electron-withdrawing end-capping groups passivates GBs and boosts perovskite grain growth.

[Study on determination of metal elements in honeysuckle by carbon pick-up acid dissolvation digestion with ICP-AES].

Honeysuckle is a lonicera plant, commonly used traditional precious raw material for medicine in China, and is a commonly used Chinese native medicine and an important material for cold drink. Honeysuckle has the effect of alleviating fever and disintoxicating, and is used mainly to treat the carbuncular swelling, and cure boils, throat rheumatism, erysipelas, painfully hot sun blood dysentery, cold, and various diseases accompanied by fever. The simultaneous determination of multi-metal elements in honeysuckle was studied by inductively coupled plasma atomic emission spectrum (ICP-AES) after carbon pick-up acid dissolvation digestion.

[Study on determination of metal elements in buds of Syzygium aromaticum (L.) Merr. et Perry by ICP-AES].

Determination of metal elements in buds of Syzygium aromaticum (L. )Merr. et Perry was studied by ICP-AES after HNO3-H2O2 digestion.

[Study on the determination of metal elements in wild jujube seed decoction by ICP-AES].

The determination of metal elements in Chinese medicine wild jujube seed decoction was studied by ICP-AES after HNO3-H2O2 digestion. The average recoveries of the method for Ca, Cr, Al, Fe, K, Mg, Mn and Zn in wild jujube seed decoction were found to be 95.5%-106.

[Study on the determination of calcium in Chinese medicine by ICP-AES].

Calcium is the necessity element in human body and its content has effect on exciting muscle or nerve. Calcium is important in the physiologic process of muscle or nervous reaction, nervous impulse transmission, heartbeat rhythm maintenance, blood solidification, cell coherence and so on. Determination of calcium element in Chinese medicine wild jujube seed decoction and radix puerariae was studied by ICP-AES after they were digested with HNO3-HClO4.
