Lipopeptide-mediated Cas9 RNP delivery: A promising broad therapeutic strategy for safely removing deep-intronic variants in .

Deep-intronic (DI) variants represent approximately 10%-12% of disease-causing genetic defects in -associated Stargardt disease (STGD1). Although many of these DI variants are amenable to antisense oligonucleotide-based splicing-modulation therapy, no treatment is currently available. These molecules are mostly variant specific, limiting their applicability to a broader patient population.

Predictive role of systemic immune-inflammation index and neutrophil/lymphocyte ratio values in infants with retinopathy of prematurity.

Purpose: To search the relationship between serum neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and systemic immune-inflammation index (SII) values with the development of retinopathy of prematurity (ROP) and the requirement for laser treatment.

Methods: This retrospective cohort study was carried out with 195 preterm infants between 2012 and 2023. The NLR, PLR, LMR, and SII values were calculated on both the first day and at the end of the first month after birth.

Amphipathic Cell-Penetrating Peptide-Aided Delivery of Cas9 RNP for In Vitro Gene Editing and Correction.

The therapeutic potential of the CRISPR-Cas9 gene editing system in treating numerous genetic disorders is immense. To fully realize this potential, it is crucial to achieve safe and efficient delivery of CRISPR-Cas9 components into the nuclei of target cells. In this study, we investigated the applicability of the amphipathic cell-penetrating peptide LAH5, previously employed for DNA delivery, in the intracellular delivery of spCas9:sgRNA ribonucleoprotein (RNP) and the RNP/single-stranded homology-directed repair (HDR) template.

Use of serum copper and zinc levels in the diagnostic evaluation of endometrioma and epithelial ovarian carcinoma.

Objective: The aim of this study is to evaluate serum copper (Cu) and zinc (Zn) levels in patients with epithelial ovarian cancer and endometrioma.

Materials And Methods: We included 21 epithelial ovarian cancer patients, 47 endometrioma patients, 31 healthy women of reproductive age, and 10 healthy women in menopause. Cu and Zn levels and Cu/Zn ratios were compared.

[Determination of Whole Genome Sequence and Resistance Genes in Hypermucoviscous Klebsiella pneumoniae with Long-Read Sequencing Technology].

Numerous virulence factors are present in the hypervirulent/hypermucoviscous Klebsiella pneumoniae, which primarily causes community-acquired infections. In recent years, hypervirulent/hypermucoviscous K.pneumoniae has acquired resistance genes and has been linked to healthcare-associated infections.
