YONPs induce selective cytotoxicity, genomic instability, oxidative stress and ROS mediated mitochondrial apoptosis in human epidermoid skin A-431 Cancer cells.

Yttrium oxide nanoparticles (YONPs) have emerged as a promising avenue for cancer therapy, primarily due to their distinctive properties that facilitate selective targeting of cancer cells. Despite their potential, the therapeutic effects of YONPs on human epidermoid skin cancer remain largely unexplored. This study was thus conducted to investigate the impact of YONPs on both human skin normal and cancer cells, with an emphasis on assessing their cytotoxicity, genotoxicity, and the mechanisms underlying these effects.

Real-World Outcomes with the KEYNOTE-522 Regimen in Early-Stage Triple-Negative Breast Cancer.

Background: This study aimed to determine if the neoadjuvant (NAT) KEYNOTE-522 regimen was associated with higher rates of pathologic complete response (pCR), corresponding to higher rates of breast conservation therapy (BCT) in early-stage triple-negative breast cancer (TNBC) patients.

Patients And Methods: Stage II-III TNBC patients diagnosed between 2019 and 2022 who underwent NAT were analyzed retrospectively. NAT with KEYNOTE-522 versus control NAT were compared for rates of BCT, axillary node dissection (ALND), pCR, and survival outcomes.

Metal complexes featuring a quinazoline schiff base ligand and glycine: synthesis, characterization, DFT and molecular docking analyses revealing their potent antibacterial, anti-helicobacter pylori, and Anti-COVID-19 activities.

Mixed ligand complexes of manganese(II), cobalt(II), copper(II), and cadmium(II)with an innovative Schiff base ligand denoted as (L), 4-(2-((1E,2E)-1-(2-(p-tolyl)hydrazineylidene)propan-2-ylidene)hydrazineyl), served as the principal ligand, while glycine (L2) was employed as secondary ligand were successfully effectively characterized through a comprehensive set of analyses, including Elemental analysis, UV-Visible, FT-IR, Mass spectra, and conductometric measurements. Density functional theory (DFT) computations were executed to discern the enduring electronic arrangement, the energy gap, dipole moment and chemical hardness of the hybrid ligand assemblies. The proposed geometry for the complexes is a distorted octahedral structure.

Characterization and Cytotoxicity Assessment of Synthesized Palladium (II) Complex-Encapsulated Zinc Oxide Nanoparticles for Cancer Treatment.

The treatment of cancer often leads to a range of adverse effects. Encapsulating drugs can mitigate these effects and enhance drug efficacy by enabling a controlled release at the site of interest. This study details the successful synthesis of zinc oxide nanoparticles (ZnONPs) through the precipitation of Zn(NO)·6HO with KOH.

Nipple necrosis rate with submuscular versus prepectoral implant-based reconstruction in nipple sparing mastectomy: Does it differ?

Background: This study aims to compare the rate of nipple necrosis between the submuscular (SM) versus the prepectoral (PP) implant placement after immediate breast reconstruction (IBR).

Methods: An institutional review board-approved database was reviewed of patients who underwent nipple sparing mastectomy (NSM) with IBR at our institution between 2016 and 2019. Patients who had SM versus PP IBR were compared.
