The effects of advanced age on electrocardiographic parameters, lipid profile and redox balance in male rats: role of long-term cinnamon consumption.

Background: Oxidative stress damages biological molecules and plays a role in aging-related cardiovascular diseases. is a major source of antioxidants that may work against age-related cardiovascular changes.

Aims: This study aimed to assess the changes in electrocardiography and lipid profile as well as indicators of the oxidant-antioxidant system with advanced age in rats.

Engineering Microgel Packing to Tailor the Physical and Biological Properties of Gelatin Methacryloyl Granular Hydrogel Scaffolds.

Granular hydrogel scaffolds (GHS) are fabricated via placing hydrogel microparticles (HMP) in close contact (packing), followed by physical and/or chemical interparticle bond formation. Gelatin methacryloyl (GelMA) GHS have recently emerged as a promising platform for biomedical applications; however, little is known about how the packing of building blocks, physically crosslinked soft GelMA HMP, affects the physical (pore microarchitecture and mechanical/rheological properties) and biological (in vitro and in vivo) attributes of GHS. Here, the GHS pore microarchitecture is engineered via the external (centrifugal) force-induced packing and deformation of GelMA HMP to regulate GHS mechanical and rheological properties, as well as biological responses in vitro and in vivo.

Multifunctional self-healing hydrogels via nanoengineering of colloidal and polymeric cellulose.

The unique features of self-healing hydrogels hold great potential for biomedical applications including injectable hydrogels for cancer treatment, procedures for tumor removal or resection. However, the fabrication of durable and multifunctional self-healing hydrogels composed of biocompatible, green building blocks via versatile synthetic methodology continues to pose a significant challenge. Here, we engineered dialdehyde cellulose (DAC, as a macromolecular bio-crosslinker), and electrosterically stabilized nanocrystalline cellulose (ENCC, as a ligand-targeted drug carrier) to facilitate a strategy for the construction of self-healing hydrogels.

Oral health knowledge, attitude, and performance of teachers and healthcare workers in special schools for the disabled children in Isfahan.

Oral health is an important aspect of general health, and is of great importance, especially in disabled children. A school is an ideal place for the implementation of preventive programs. Considering the significance of the prevention of dental caries and periodontal disease in disabled children, and the important role of teachers in the oral health promotion of students, this study aimed to assess the oral health knowledge, attitude, and performance of teachers and healthcare workers in special schools for the disabled children in Isfahan.

Iron inhibits glioblastoma cell migration and polarization.

Glioblastoma is one of the deadliest malignancies facing modern oncology today. The ability of glioblastoma cells to diffusely spread into neighboring healthy brain makes complete surgical resection nearly impossible and contributes to the recurrent disease faced by most patients. Although research into the impact of iron on glioblastoma has addressed proliferation, there has been little investigation into how cellular iron impacts the ability of glioblastoma cells to migrate-a key question, especially in the context of the diffuse spread observed in these tumors.
