Evolution of Two-Dimensional Perovskite Films Under Atmospheric Exposure and Its Impact on Photovoltaic Performance.

Two-dimensional (2D) Ruddlesden-Popper perovskites (RPPs) have garnered significant attention due to their enhanced stability compared with their three-dimensional counterparts. However, the power conversion efficiency (PCE) of 2D perovskite solar cells (2D-PSCs) remains lower than that of 3D-PSCs. Understanding the microstructural evolution of 2D perovskite films during fabrication is essential for improving their performance.

Targeted metabolomics reveals novel diagnostic biomarkers for colorectal cancer.

Colorectal cancer (CRC) is a prevalent malignant tumor worldwide, with a high mortality rate due to its complex etiology and limited early screening techniques. This study aimed to identify potential biomarkers for early detection of CRC utilizing targeted metabolite profiling of platelet-rich plasma (PRP). Based on multiple reaction monitoring (MRM) mode, liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis identified metabolites in PRP collected from patients with CRC (n = 70) and healthy controls (n = 30).

Design, synthesis and activity evaluation of reduction-responsive anticancer peptide temporin-1CEa drug conjugates.

Membranes that destroy anticancer peptides can bind to negatively charged cancer cell membranes through electrostatic interactions, destroying their functions and leading to cancer cell necrosis. Temporin-1CEa, obtained from the skin secretions of the Chinese frog Rana chensinensis, is an anticancer peptide with 17 amino acid residues that exhibits concentration-dependent cytotoxicity against a variety of cancer cell lines, although it has no obvious cytotoxicity to normal HUVECs. In this work, we designed and synthesized 12 derivative peptides through double-cysteine scanning of temporin-1CEa-truncated peptides.

We initially studied the effect of depression on dementia incidence across four subgroups characterized by courses of depressive symptoms.

Investigation of the anti-Huanglongbing effects using antimicrobial lipopeptide and phytohormone complex powder prepared from MG-2 fermentation.

Global citrus production has been severely affected by citrus Huanglongbing (HLB) disease, caused by Candidatus Liberibacter asiaticus (Clas), and the development of effective control methods are crucial. This study employed antimicrobial lipopeptide and phytohormone complex powder (L1) prepared from the fermentation broth of the endophytic plant growth promoting bacterium (PGPB) of strain MG-2 to treat Liberibacter asiaticus (Las)-infected ' 'Chun Jian' plants. Real-time fluorescence quantitative polymerase chain reaction (qPCR) and PCR were employed for disease detection.

Energetic MOF-derived FeC nanoparticles encased in N,S-codoped mesoporous pod-like carbon nanotubes for efficient oxygen reduction reaction.

The rational design of advanced oxygen reduction reaction (ORR) catalysts is essential to improve the performance of energy conversion devices. However, it remains a huge challenge to construct hierarchical micro-/meso-/macroporous nanostructures, especially mesoporous transport channels in catalysts, to enhance catalytic capability. Herein, motivated by the characteristics of energetic metal-organic frameworks (EMOFs) that produce an abundance of gases during high-temperature pyrolysis, we prepared a unique tetrazine-based EMOF-derived electrocatalyst (denoted as FeC@NSC-900) consisting of highly dispersed FeC nanoparticles and N,S-codoped mesoporous carbon nanotubes.

Donor MHC-specific thymus vaccination allows for immunocompatible allotransplantation.

Organ transplantation is the last-resort option to treat organ failure. However, less than 10% of patients benefit from this only option due to lack of major histocompatibility complex (MHC)-matched donor organs and 25%-80% of donated organs could not find MHC-matched recipients. T cell allorecognition is the principal mechanism for allogeneic graft rejection.

Nucleophilic addition of bulk chemicals with imines using N-functionalized hydroxylamine reagents as precursors.

C-C and C-X bond forming reactions are essential tools in organic synthesis, constantly revolutionizing human life. Among the key methods for constructing new chemical bonds are nucleophilic addition reactions involving imines. However, the inherent challenges in synthesizing and storing imines have stimulated interest in designing stable precursors, which generates imines in situ during the reaction.

Investigating the Role of TRPV4 and GPR35 Interaction in Endothelial Dysfunction in Aging Mice.

Endothelial dysfunction, characterized by a decline in endothelial physiological functions, is a significant aspect of cardiovascular aging, contributing notably to arterial stiffness, atherosclerosis, and hypertension. Transient receptor potential channel V4 (TRPV4), a key member of Ca-permeable channels, plays a crucial role in maintaining vascular functions. However, the role and mechanisms of TRPV4 in aging-related endothelial dysfunction remain incompletely understood.

Bidirectional associations of grip strength-gait speed with mild cognitive impairment and specific cognitive abilities among older adults: A longitudinal analysis.

Background: Previous studies showed that physical performance was associated with mild cognitive impairment (MCI). As the easily measured aging biomarkers, grip strength and gait speed could effectively reflect physical function. However, whether grip strength, gait speed, and the combination of the two were bidirectionally associated with MCI and specific cognitive function domains, have not been explored.
