Local Khulays clay was modified to prepare polystyrene clay nanocomposite (PCN) coatings on carbon steel. The PCN coatings were added to microcapsules (MCs) loaded with the corrosion inhibitor PCN(MC). The microcapsules were prepared by the encapsulation of rare-earth metal Ce ions and isobutyl silanol into polystyrene via the double emulsion solvent evaporation (DESE) technique.

Background: Stroke is a significant contributor to both mortality and compromised physical function. Endovascular thrombectomy (EVT) is now the recognized standard of care for anterior circulation acute ischemic stroke (AIS) with large vessel occlusion (LVO), especially when favorable brain images are evident within 24 h of symptom onset. This study elucidated the characteristics, clinical profiles, and outcomes of patients who underwent EVT for AIS.

Article Synopsis
  • Hemostatic agents are commonly used in dental procedures to control bleeding, but they can negatively impact the bonding of resin composites to dentin, making their removal before bonding important.
  • The study involved 90 premolar teeth divided into groups treated with either no hemostatic agent, ferric sulfate, or aluminum chloride, with cleanup methods including water, phosphoric acid, katana cleaner, and air abrasion.
  • Results showed that the type of hemostatic agent and cleansing method significantly affected bond strength, with phosphoric acid yielding the best results and ferric sulfate showing the lowest bond strength.

The aluminum industry generates a significant amount of red mud as solid waste. This waste is high in mineral content, particularly metal oxides, and difficult to treat, manage, and recycle, resulting in malignant environmental effects. A simple, scalable, and precisely controlled hydrochloric acid treatment transforms the red mud into a useful product by selectively removing electrochemically inactive phases.

Aqueous zinc-ion batteries (AZIBs) are a potential new technology in energy storage due to their high energy density, affordability, and environmental friendliness. The development of AZIBs is still hampered by unchecked zinc dendrite formation during cycling, which results in an unstable interface, a short cycling life, and a considerable capacity decline with security issues. Herein, we demonstrate a novel nanofiber membrane based on polyetherimide-polyacrylonitrile (PEI/PAN) polymer via electrospinning method with entangled nanofibers for AZIBs applications.

Background In light of the trend of using zirconia crowns, clinicians will likely face abutment included in removable partial dentures (RPD) designs with existing zirconia. However, the decision to replace the existing crown with a surveyed crown or modify the existing crown to accept the RPD is unclear. To the best of our knowledge, there is a lack of literature on the effect of preparing a rest seat on the existing monolithic zirconia crown in the patient's mouth on the fracture resistance of the crown.

BACKGROUND Dentin contamination with hemostatic agents before bonding indirect restorations negatively affects the bond strength. However, the consensus on which materials could be used to clean contamination of hemostatic agents has not been explored. The aim of this study was to assess the effect of Katana Cleaner applied on the surface of dentin contaminated with hemostatic agents on the shear bond strength (SBS) of self-adhesive resin cement by comparing it with three other surface cleaners.

Bleomycin is an effective antibiotic with a significant anticancer properties, but its use is limited due to its potential to induce dose-dependent pulmonary fibrosis. Therefore, this study aimed to assess the therapeutic potential of Capsaicin as an additional treatment to enhance patient tolerance to Bleomycin compared to the antifibrotic drug Pirfenidone. Pulmonary fibrosis was induced in rats through by a single intratracheal Bleomycin administration in day zero, followed by either Capsaicin or Pirfenidone treatment for 7 days.

Background: Following transient ischemic attack (TIA) and minor stroke, the risk of recurrent stroke can be significantly reduced with short-duration dual antiplatelet therapy (DAPT). We wish to investigate whether 10 days of DAPT is as effective as 21 days' treatment.

Study Design: This is an open-label, randomized, parallel-group study comparing whether 10 days of DAPT treatment (ASA + clopidogrel) is non-inferior to 21 days of DAPT in patients with acute ischemic stroke (AIS) or high-risk TIA.
