The effect of biosynthesized zinc oxide nanoparticles on gene expression and apoptosis in triple-negative breast cancer cells.

Objective(s): Some forms of breast cancer such as triple-negative phenotype, are serious challenge because of high metastatic cases, high mortality and resistance to conventional therapy motivated the search for alternative treatment approaches. Nanomaterials are promising candidates and suitable alternatives for improving tumor and cancer cell treatments.

Materials And Methods: Biosynthesis of ZnO NPs by help of Berberis integerrima fruit extract, has been done.

Bioinspired synthetic peptide-based biomaterials regenerate bone through biomimicking of extracellular matrix.

There have been remarkable advancements in regenerative medicine for bone regeneration, tackling the worldwide health concern of tissue loss. Tissue engineering uses the body's natural capabilities and applies biomaterials and bioactive molecules to replace damaged or lost tissues and restore their functionality. While synthetic ceramics have overcome some challenges associated with allografts and xenografts, they still need essential growth factors and biomolecules.

Small but mighty: nanoemulsion particle size dictates bone regeneration potential of FTY720.

The burgeoning field of nano-bone regeneration is yet to establish a definitive optimal particle size for nanocarriers. This study investigated the impacts of nanocarrier's particle size on the bone regeneration efficacy of fingolimod (FTY720)-loaded nanoemulsions. Two distinct particle sizes (60 and 190 nm, designated as NF60 and NF190, respectively) were produced using low-energy and high-energy emulsion techniques, maintaining a consistent surfactant, co-surfactant, and oil.

Unveiling the superior function of RADA in bone regeneration compared to KSL as two critical cores within self-assembling peptide nanofibers: Insights from in vitro and in vivo studies.

Introduction: Self-assembling peptide nanofibers have emerged as promising biomaterials in the realm of bone tissue engineering due to their biocompatibility, biodegradability, and ability to mimic the native extracellular matrix. This study delved into the comparative efficacy of two distinct self-assembling peptide nanofibers, RADA-BMHP1 and KSL-BMHP1, both incorporating the biological motif of BMHP1, but differing in their core peptide sequences.

Methods: Cell viability and osteogenic differentiation in rat mesenchymal stem cells (rMSCs), and bone regeneration in rat were compared.

Latest Findings on the Effects of Gold Nanoparticles on the Storage Quality of Blood Products (2011-2022) - A Narrative Review.

A wide range of challenges are faced during the storage of blood products, including storage lesions, contamination that must be removed, and cell and protein damage due to chemicals and UV exposure. The enhancement of stability exhibited by gold nanoparticles (GNPs) is a notable advantage of these nanoparticles for the storage of blood products. The results of our review of articles from 2011 to 2022 discussing the effect of GNPs on blood products revealed that in RBCs, the dose, concentration, amount, and surface charge of GNPs significantly affect their compatibility.
