A novel long non-coding RNA MIR4500HG003 promotes tumor metastasis through miR-483-3p-MMP9 axis in triple-negative breast cancer.

Breast cancer (BC) is the most common cancer and the leading cause of cancer-related deaths in women worldwide. The 5-year survival rate is over 90% in BC patients, but once BC cells metastasis into distal organs, it is dramatically decreasing to less than 30%. Especially, triple-negative breast cancer (TNBC) patients usually lead to poor prognosis and survival because of metastasis.

The default mode network is affected in the early stage of simian immunodeficiency virus infection: a longitudinal study.

Acquired immune deficiency syndrome infection can lead to cognitive dysfunction represented by changes in the default mode network. Most recent studies have been cross-sectional and thus have not revealed dynamic changes in the default mode network following acquired immune deficiency syndrome infection and antiretroviral therapy. Specifically, when brain imaging data at only one time point are analyzed, determining the duration at which the default mode network is the most effective following antiretroviral therapy after the occurrence of acquired immune deficiency syndrome.

[Effect of bloodletting at tip of ear with different amounts on pain in patients with early-stage stye: a randomized controlled trial].

Objective: To compare the curative effect between bloodletting at tip of ear with different amounts combined with western medication and western medication alone for early-stage stye.

Methods: A total of 108 patients with early-stage stye were randomly divided into a 50 μL group (36 cases, 4 cases dropped off), a 100 μL group (36 cases, 2 cases dropped off) and a western medication group (36 cases, 5 cases dropped off). The patients in the western medication group were treated with levofloxacin eye drops and levofloxacin hydrochloride eye gel.

Bloodletting at EX-HN6 as an adjunctive therapy to eye drops for stye: A meta-analysis.

Background: This study evaluated the effectiveness and safety of bloodletting (BL) at ear-apex (EX-HN6) as an adjunctive therapy to eye drops for stye.

Methods: This study systematically searched electronic databases from inception to March 1, 2020 in PUBMED, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journals Full-text Database, and WanFang Database. All potential randomized controlled trials (RCTs) investigating the effectiveness and safety of BL at EX-HN6 as an adjunctive therapy to eye drops for stye were included in this study.

Diammonium-Cesium Lead Halide Perovskite with Phase-Segregated Interpenetrating Morphology for Photovoltaics.

The insertion of organic spacers into halide perovskite slabs has offered a trade-off between the efficiency and stability of perovskite solar cells (PSCs). The layered structure of diammonium-intercalated cesium lead halide perovskites is virtually unexplored, in contrast to several works on the monoammonium system. In this report, we find that perovskite with 1,4-butanediammonium (BDA) and cesium cations can only form = 1 and = 2 layered isologues defined by the chemical formula of (BDA)CsPb(IBr), while the = 3-4 ones will self-construct into unique heterostructures comprising separated quantum wells (QWs; = 1-2) and 3D ( = ∞) perovskites.

Enhanced moisture stability of metal halide perovskite solar cells based on sulfur-oleylamine surface modification.

As one of the most promising light-harvesting materials, perovskites have drawn tremendous attention for their unique advantages, such as high efficiency, low cost and facile fabrication compared with other photovoltaic materials. Nevertheless, poor moisture tolerance of the perovskites greatly hampers the operation of such devices and hinders their commercialization. Herein, we demonstrate a facile dipping treatment using sulfur-oleylamine solution for surface atomic modulation of perovskite films.

A Gradient Heterostructure Based on Tolerance Factor in High-Performance Perovskite Solar Cells with 0.84 Fill Factor.

A gradient heterosturcture is one of the basic methods to control the charge flow in perovskite solar cells (PSCs). However, a classical route for gradient heterosturctures is based on the diffusion technique, in which the guest ions gradually diffuse into the films from a concentrated source of dopants. The gradient heterosturcture is only accessible to the top side, and may be time consuming and costly.

In situ and real-time ToF-SIMS analysis of light-induced chemical changes in perovskite CHNHPbI.

A hybrid light/ToF-SIMS system was used to analyze the dynamic chemical changes of perovskite CH3NH3PbI3 films under light illumination, in order to reveal the mechanism of light instability for perovskite materials. Real-time material degradation and quasi-reversible iodine migration were successfully observed.

A Solution-Processed Transparent NiO Hole-Extraction Layer for High-Performance Inverted Perovskite Solar Cells.

A highly transparent NiO layer was prepared by a solution processing method with nickel(II) 2-ethylhexanoate in non-polar solvent and utilized as HTM in perovskite solar cells. Excellent optical transmittance and the matched energy level lead to the enhanced power conversion efficiency (PCE, 18.15 %) than that of conventional sol-gel-processed NiO-based device (12.
