Mutations in CPAMD8 have been linked to anterior segment dysgenesis and primary congenital glaucoma. We utilized CRISPR/Cas9 technology to establish a homozygous CPAMD8 knockout human embryonic stem cell line for differentiating retinal organoids, with the intent of exploring the role of CPAMD8 in the early development of the human eye.

Methods: This study retrospectively analyzed 216 prostate cancer patients who had [Ga]Ga-PSMA-11 PET/CT before radical prostatectomy. False-positive lesion was defined as suspicious lesion with PRIMARY score ≥ 3 on PET/CT but benign on whole-mount pathology.
Purpose: This study aims to investigate the potential effect of compromised structural integrity on cerebral aging and cognitive function in cerebral small vessel disease (CSVD).

Intramolecular G-quadruplexes (G4) are four-stranded nucleic acid structures formed by guanine-rich sequences that play crucial roles in various biological processes, such as gene regulation and genome stability. However, the formation and function of intermolecular G4, especially in RNA, remain less understood. In this study, it was demonstrated that poly-guanine (poly-G) RNA sequences can form ultra-stable intermolecular G4 structures, particularly when the guanine content exceeds five.

However, AAVO has low solubility, stability, and bioavailability. Here, to address these issues, a nanoemulsion system of volatile oil (AAVO-Ne) is constructed using phase transition titration, and the conditions are continuously optimized to combine it with chitosan, forming a chitosan composite of the volatile oil nanoemulsion (AAVO-NeCs).

However, this modification can result in ribosomal frameshifts, reduced immunogenicity, and higher production costs. This study aimed to explore the potential of unmodified mRNA sequences for varicella-zoster virus (VZV) and evaluate whether codon optimization could overcome the limitations of pseudouridine modification.

Pampus argenteus, a species distributed throughout the Indo-West Pacific, plays a significant role in the yield of aquaculture species. However, cultured P. argenteus has always been characterised by unbalanced growth synchronisation among individuals, slow growth rate, and lack of excellent germplasm resources.

In response to this unprecedented global health crisis, significant advancements were made in the mRNA vaccine technology. In this study, we have compared the difference between two SARS-CoV-2 receptor-binding domain (RBD) mRNA-Lipid nanoparticle (LNP) vaccines prepared from two different ionizable cationic lipids: ALC-0315 and MC3.
View Article and Find Full Text PDFBackground: As global food production continues to surge, the widespread use of herbicides has also increased concurrently, posing challenges like health risks and environmental pollution. Traditional detection methods for pesticide residues, such as diquat (DQ), were hampered by limitations like high expenses, lengthy detection times and complex operations, restricting their practical application in rapid clinical diagnosis.
Results: In light of the pressing necessity for the identification of minute pesticide residues and the intrinsic constraints of small molecule analysis, a novel chromophotometric biosensor targeting small molecules was developed based on bi-epitopes on single antibody to immobilize two DQ-PAL, inhibiting the hybridization of DQ-PAL.
Propose: This study aimed to evaluate the efficacy and safety of neoadjuvant treatment of darolutamide, a next-generation androgen receptor inhibitor, plus androgen deprivation therapy (ADT) for patients with locally advanced prostate cancer (LAPC).
Methods: This single-arm, multicenter, open-label phase II trial (ClinicalTrials.gov: NCT05249712, 2022-01-01), recruited 30 localized high-risk/very high-risk prostate cancer (HRPCa/VHRPCa) patients from three centers in China between 2021 and 2023.
The brominated flame retardant 2, 2', 4, 4'-tetrabromodiphenyl ether (PBDE-47) is known as a developmental neurotoxicant, yet the underlying mechanisms remain unclear. This study aims to explore its neurotoxic mechanisms by integrating network toxicology with transcriptomics based on human neural precursor cells (hNPCs) and neuron-like PC12 cells. Network toxicology revealed that PBDE-47 crosses the blood-brain barrier more effectively than heavier PBDE congeners, and is associated with disruptions in 159 biological pathways, including cytosolic DNA-sensing pathway, ferroptosis, cellular senescence, and chemokine signaling pathway.
