Ferroptosis: A Key Driver in Atherosclerosis Progression and Arterial Disease.

Atherosclerosis (AS) is a growing global health epidemic and is the leading cause of cardiovascular health problems, including ischemic stroke, coronary artery disease, and peripheral vascular disease. Despite extensive research on the underlying mechanisms of AS, iron remains an under-investigated mediator in the atherosclerotic process. Iron's involvement in AS is primarily linked to the iron-induced programmed cell death process known as ferroptosis.

Titanate-polyurethane-chitosan ternary nanocomposite as an efficient coating for steel against corrosion.

In this study, a titanate-polyurethane-chitosan ternary nanocomposite was prepared by physical mixing. Sodium titanate nanotubes (Na-TNTs) were prepared by the hydrothermal method, and chitosan was extracted from shrimp shell. Na-TNTs were mixed with polyurethane (PU) of different ratios by weight, and chitosan was added after optimization.

Are Bone Expansion Techniques Effective for Implant Placement in Narrow Alveolar Ridges?

Because of the fact that sufficient alveolar ridge bone is essential for the success of implant placement, the authors often face a challenge with augmenting residual maxillary alveolar ridges. The aim of the study was to compare the amount of ridge gain by the Osseodensification method with the manual bone expanders method for healed edentulous sites in the maxilla at different time intervals (immdiate postoperative and 6 mo postoperative). Two groups were equally and randomly divided with a total of 14 implants (Biohorizons) placed in the maxillary arch for 8 patients, osseodensification was used for 1 group (group 1), whereas manual threaded expanders (bone spreaders) was used for the other group (group 2).

The purpose of this study was to evaluate the incidence and predictors of malignant soft tissue deposits (MSTDs) in advanced laryngeal carcinoma. MSTDs prognostic value on locoregional recurrence within 2 years after curative surgery was also studied. 40 patients with cT3/cT4 N0 laryngeal squamous cell carcinoma (SCC) were prospectively involved in the study.
