Storing perovskite precursor solutions under ambient conditions poses a significant challenge to commercialization, as humidity and oxidation accelerate ageing and introduce defects in devices. A major contributor to solution ageing and impurity perovskite phases is the deprotonation of hybrid organic cations, specifically methylammonium (MA) and formamidinium (FA). In this work, a proton-rich additive, 4-(aminomethyl)pyridine 2-iodide, is used to inhibit MA deprotonation in precursor solutions by generating free H, thereby mitigating the degradation of organic cations under oxygen and humidity stress.

However, conventional DWI method, such as 2D GRE DWI, is limited in its application due to the long acquisition time and relatively thick slice.
Purpose: To develop a method combining 3D golden-angle radial sampling with keyhole reconstruction (GRSK) for accelerating Xe multiple b-values DWI and obtaining thinner slice.
Anaplastic thyroid carcinoma (ATC) is a rare and highly aggressive malignancy characterized by a poor prognosis, with a median survival time of approximately 3 to 4 months. In this report, we present a case involving a 59-year-old patient diagnosed with ATC, who experienced swift local recurrence and pulmonary metastasis following radical thyroidectomy. Comprehensive Sanger sequencing of the resected tumor tissue revealed no mutations in the TERT promoter or the BRAF V600E gene.

As a gatekeeper of the airway epithelial cells, E-cadherin is not only a critical component for the maintenance of epithelial integrity, but also engaged in pathological processes through the release of a soluble form (sE-cadherin). This study was aimed to investigate the role of sE-cadherin in ALI/ARDS. Serum samples from patients with ARDS and healthy volunteers were collected for the detection of sE-cadherin.

To explore lipid function in cotton fiber development, the lipid composition and content were detected by untargeted and targeted lipidomics. Compared with rapid elongation fibers, the lipid intensity of 16 sub-classes and 56 molecular species decreased, while only 7 sub-classes and 26 molecular species increased in the fibers at the stage of secondary cell wall deposition.

Method: Between July 2015 and December 2022, 439 patients who underwent 3D image-guided VATS segmentectomy for early-stage lung cancer were enrolled. Based on whether preoperative localization was performed, the patients were divided into two groups as follows: the localization (n = 96) and nonlocalization groups (n = 343).
Long non-coding RNAs (lncRNAs) are a class of non-coding RNA molecules with transcripts longer than 200 bp, which were initially thought to be noise from genomic transcription without biological function. However, since the discovery of H19 in 1980 and Xist in 1990, increasing evidence has shown that lncRNAs regulate gene expression at epigenetic, transcriptional, and post-transcriptional levels through specific regulatory actions and are involved in the development of cancer and other diseases. Despite many lncRNAs being expressed at lower levels than those of protein-coding genes with less sequence conservation across species, lncRNAs have become an intense area of RNA research.

By adjusting the heterogeneity coefficient and clustering coefficient of the hyperbolic scale-free network, four distinct network structures with notable differences can be obtained. We then map pairwise and three-way interactions to 2-hyperedges and 3-hyperedges, constructing a hypergraph model with higher-order interactions.

Several technologies, both natural and synthetic are being investigated to mitigate enteric methane emissions. Macroalgae derived feed ingredients that contain bromoform, a recognised inhibitor of methanogenesis, are an effective natural approach for methane mitigation.

However, the poor diffusion and penetration capabilities of recently developed biological enzyme-functionalized antibacterial nanoparticles in biofilm severely impair the eradication efficacy of deep-seated bacteria. Herein, a photothermal-driven nanomotor (denoted as APPNM) is developed for enhancing the elimination of drug-resistant biofilms and the eradication of deep-seated bacteria.

Here, we identify the E3 ubiquitin ligase E3TCD1 and develope a Targeted Condensation-prone-protein Degradation (TCD) strategy. The X-E3TCD1 fusion protein acts as a genetically engineered degrader, selectively targeting endogenous proteins prone to condensation.
