Bioprospecting of culturable marine biofilm bacteria for novel antimicrobial peptides.

Antimicrobial peptides (AMPs) have become a viable source of novel antibiotics that are effective against human pathogenic bacteria. In this study, we construct a bank of culturable marine biofilm bacteria constituting 713 strains and their nearly complete genomes and predict AMPs using ribosome profiling and deep learning. Compared with previous approaches, ribosome profiling has improved the identification and validation of small open reading frames (sORFs) for AMP prediction.

Naked eye three-dimensional teaching assistant system applied to undergraduate medical imaging education: A pilot study.

The traditional approach of using PowerPoint (PPT) presentations in medical imaging theory classes hinders the spatial thinking ability of most students. Consequently, the learning outcomes are often unsatisfactory. This article proposes a naked eye three-dimensional (3D) medical imaging teaching assistant app based on augmented reality (AR) technology to enhance learning interest, teaching interaction, and effectiveness.

On the role of familiarity and developmental exposure in music-evoked autobiographical memories.

Music-evoked autobiographical memories (MEAMs) are typically elicited by music that listeners have heard before. While studies that have directly manipulated music familiarity show that familiar music evokes more MEAMs than music listeners have not heard before, music that is unfamiliar to the listener can also sporadically cue autobiographical memory. Here we examined whether music that sounds familiar even without previous exposure can produce spontaneous MEAMs.

N-Heterocyclic carbene-functionalized metal nanoparticles and nanoclusters for nanocatalysis.

N-Heterocyclic carbenes (NHCs) have recently emerged as a popular ligand for the functionalization of metal nanoparticles and atomically precise metal clusters. The strong electron-donating properties of NHCs and robust NHC-metal covalent bonding endow metal nanostructures with improved stability and enhanced catalytic performances. In this review, we focus on NHC-coordinated metal nanoparticles and nanoclusters for the electrochemical CO reduction reaction (eCORR), selective hydrogenation of unsaturated compounds, and asymmetrical catalytic reactions.

CaF Nanoparticle-Induced γ-CsPbIBr Heterogeneous Crystallization for High-Efficiency Flexible All-Inorganic Perovskite Solar Cells.

All-inorganic CsPbI films necessitate higher annealing temperatures for high-quality crystallization. Consequently, the conventional low-temperature solution approach often results in poor crystallization in flexible CsPbI films, significantly degrading the optoelectronic performance and stability of flexible perovskite solar cells (f-PSCs). Herein, a heterogeneous CaF nanocrystal seed-induced strategy has been successfully utilized to achieve enhanced crystallization of a flexible CsPbIBr film.

Role of HPV E7/miR-143-3p/SH2D3A pathway in regulating the occurrence and development of cervical cancer.

Objective: This study aims to explore the role of SH2D3A in cervical cancer, as well as its potential interaction with human papillomavirus (HPV) E7 and microRNA (miRNA).

Methods: Quantitative reverse transcription polymerase chain reaction (qRT-PCR) and immunohistochemistry were used to compare the expressions of SH2D3A in tissues. To assess the effects of SH2D3A on cervical cancer cell phenotypes, SH2D3A was knocked down in SiHa and HeLa cells, followed by cell proliferation (Cell Counting Kit-8 assay), apoptosis (flow cytometry), and invasion (Transwell assay) analyses.

Genomic Analysis of Novel Bacterial Strains Isolated from Marine Biofilms.

Bacteria from the genus are distributed across various marine habitats and play a significant role in sulfur cycling. However, the metabolic features of inhabiting marine biofilms are still not well understood. Here, complete genomes and paired metatranscriptomes of eight strains, isolated from biofilms on subtidal stones, have been analyzed to explore their central energy metabolism and potential of secondary metabolite biosynthesis.

Anti-Solvent-Free Fabrication of Stable FACsPbI Perovskite Solar Cells with Efficiency Exceeding 24.0% through a Naphthalene-Based Passivator.

The anti-solvent-free fabrication of high-efficiency perovskite solar cells (PSCs) holds immense significance for the transition from laboratory-scale to large-scale commercial applications. However, the device performance is severely hindered by the increased occurrence of surface defects resulting from the lack of control over nucleation and crystallization of perovskite using anti-solvent methods. In this study, 2-(naphthalen-2-yl)ethylamine hydriodide (NEAI) is employed as the surface passivator for perovskite films without using any anti-solvent.

Telomere Erosion and Depressive Symptoms Across Development Following Institutional Care.

Objective: A large literature has identified exposure to early caregiving adversities as a potent risk for developing affective psychopathology, with depression, in particular, increasing across childhood into adolescence. Evidence suggests telomere erosion, a marker of biological aging, may underlie associations between adverse early-life experiences and later depressive behavior; yet, little is understood about this association during development.

Method: The current accelerated longitudinal study examined concurrent telomere length and depressive symptoms concurrently, 2 and 4 years later, from the preschool period through adolescence among children exposed (n =116) and not exposed (n = 242) to early previous institutional (PI) care.

HR121 targeting HR2 domain in S2 subunit of spike protein can serve as a broad-spectrum SARS-CoV-2 inhibitor intranasal administration.

The continuously emerging SARS-CoV-2 variants pose a great challenge to the efficacy of current drugs, this necessitates the development of broad-spectrum antiviral drugs. In the previous study, we designed a recombinant protein, heptad repeat (HR) 121, as a variant-proof vaccine. Here, we found it can act as a fusion inhibitor and demonstrated broadly neutralizing activities against SARS-CoV-2 and its main variants.
