Electrospun nanofibrous scaffolds reinforced with therapeutic lithium/manganese-doped calcium phosphates: Advancing skin cancer therapy through apoptosis induction.

In the current study we fabricated potent materials by incorporating therapeutic elements into calcium phosphates (CPs) to combat cancer. This involved synthesizing manganese (Mn)- and lithium (Li)-doped CPs and loading them into electrospun nanofibers (NFs) composed of chitosan (CS) and polyethylene oxide (PEO). The characterized CPs exhibited excellent properties, including a particle size of 47-75 nm, surface charge of -(30-56) mV, and specific surface area of 75-266 m/g.

The Role of mTOR in the Doxorubicin-Induced Cardiotoxicity: A Systematic Review.

Doxorubicin (DOX) is a chemotherapy drug known to induce metabolic changes in the heart, leading to potential heart toxicity. These changes impact various cellular functions and pathways such as disrupting the mechanistic target of rapamycin (mTOR) signaling pathway. The study aimed to investigate the effect of DOX on the mTOR pathway through an in vivo systematic review.

Biocompatible Nanocomposites for Postoperative Adhesion: A State-of-the-Art Review.

To reduce and prevent postsurgical adhesions, a variety of scientific approaches have been suggested and applied. This includes the use of advanced therapies like tissue-engineered (TE) biomaterials and scaffolds. Currently, biocompatible antiadhesive constructs play a pivotal role in managing postoperative adhesions and several biopolymer-based products, namely hyaluronic acid (HA) and polyethylene glycol (PEG), are available on the market in different forms (e.

Effects of Bioactive Glasses (BGs) on Exosome Production and Secretion: A Critical Review.

There is an increasing trend toward the application of bioactive glasses in different areas of biomedicine, including tissue engineering and oncology. The reason for this increase is mostly attributed to the inherent properties of BGs, such as excellent biocompatibility, and the ease of tailoring their properties by changing, for example, the chemical composition. Previous experiments have demonstrated that the interactions between BGs and their ionic dissolution products, and mammalian cells, can affect and change cellular behaviors, and thereby govern the performance of living tissues.

Antioxidant Effects of Bioactive Glasses (BGs) and Their Significance in Tissue Engineering Strategies.

Elevated levels of oxidative stress are usually observed following injuries, leading to impaired tissue repair due to oxidation-related chronic inflammation. Several attempts have been made to manage this unfavorable situation, and the use of biomaterials with antioxidant activity is showing great promise in tissue engineering and regenerative medicine approaches. Bioactive glasses (BGs) are a versatile group of inorganic substances that exhibit an outstanding regenerative capacity for both hard and soft damaged tissues.

Osteogenic Potential of Magnesium (Mg)-Doped Multicomponent Bioactive Glass: In Vitro and In Vivo Animal Studies.

The use of bioactive glasses (BGs) has been quite fruitful in hard tissue engineering due to the capability of these materials to bond to living bone. In this work, a melt-derived magnesium (Mg)-doped BG (composition: 45SiO-3PO-26CaO-15NaO-7MgO-4KO (mol.%)) was synthesized for being used in bone reconstruction.

DFT simulation towards evaluation the molecular structure and properties of the heterogeneous CMgO nano-cage as selective nano-sensor for H and N gases.

Adsorption of hydrogen (H) and nitrogen (N) molecules was analyzed on a new fullerene-like CMgO nano-cage, composed of magnesium, oxygen, and carbon, using density functional theory. A detailed analysis of the energy, geometry, and electronic structure of various H and N adsorptions on the cluster surface was performed. The adsorption energies of H and N were estimated to ranging from -0.
