Article Synopsis
  • - Hydroxyapatite (HAp) and its composites, which incorporate metal nanoparticles like copper, zinc, and silver, show great potential in healthcare due to their biocompatibility and strong antimicrobial properties, making them useful in preventing infections in medical settings.
  • - The study examined the antimicrobial efficacy of various HAp-based materials using advanced techniques, finding that all modified composites could inhibit bacterial growth, with the 5% silver-loaded variant (5% Ag/HAp) demonstrating the strongest antibacterial effects against E. coli and S. aureus.
  • - Results suggest that these HAp-based composites could effectively be used in infection control applications, such as on medical instruments and textiles, thereby improving safety in healthcare environments.

The lack of practical platforms for bacterial separation remains a hindrance to the detection of bacteria in complex samples. Herein, a composite cryogel was synthesized by using clickable building blocks and boronic acid for bacterial separation. Macroporous cryogels were synthesized by cryo-gelation polymerization using 2-hydroxyethyl methacrylate and allyl glycidyl ether.

λ-carrageenan oligosaccharides can be widely applied in the food, pharmaceutical, medicine and cosmetic industries due to their abundant bioactivities, and they are important products for the high-value utilization of λ-carrageenan. However, oligosaccharides with different degrees of polymerization have different properties, and the final products of λ-carrageenase reported so far are mainly λ-neocarrabiose, λ-neocarratetraose and λ-neocarrahexaose without longer-chain oligosaccharides. Further research is consequently required.

Aims: Many European healthcare providers struggle to adopt multidisciplinary, integrated care pathways for people with heart failure (HF) as recommended by the European Society of Cardiology. PRO-HF (Program to Optimize Heart Failure Patient Pathways) was developed to help clinicians identify strengths, gaps, and shortcomings in their HF pathways and support tailored interventions to optimize pathways and enhance patient care. We report initial findings from baseline assessments of HF pathway characteristics and challenges from 10 hospitals in six European countries (France, Ireland, Portugal, Spain, The Netherlands, and United Kingdom).

To achieve effective separation and enrichment of bacteria, a novel synthetic scheme was developed to synthesize star-style boronate-functionalized copolymers with excellent hydrophilicity and temperature and pH responsiveness. A hydrophilic copolymer brush was synthesized by combining surface-initiated atom-transfer radical polymerization with amide reaction using bovine serum albumin as the core. The copolymer brush was further modified by introducing and immobilizing fluorophenylboronic acids through an amide reaction, resulting in the formation of boronate affinity material BSA@poly(NIPAm--AGE)@DFFPBA.

  • This study aimed to compare the safety and effectiveness of Dual Antiplatelet Therapy (DAPT) versus Intravenous Tissue Plasminogen Activator (IV t-PA) for treating minor Acute Ischemic Stroke (AIS).
  • A meta-analysis of five studies involving nearly 6,200 patients found no significant differences in treatment efficacy based on modified Rankin scale scores or mortality rates between the two therapies.
  • DAPT showed a notably lower risk of bleeding and symptomatic intracranial hemorrhage compared to IV t-PA, suggesting it may be a safer option.

Huntington's disease (HD) is an autosomal-dominant neurodegenerative disorder characterized by motor, psychiatric and cognitive symptoms. Injection of 3-nitropropionic acid (3-NP) is a widely used experimental model for induction of HD. The current study aimed to inspect the potential neuroprotective properties of azilsartan (Azil), an angiotensin II type 1 receptor blocker (ATR1), in 3-NP-induced striatal neurotoxicity in rats.
