8-Anilino-1-naphthalenesulfonate-Conjugated Carbon-Coated Ferrite Nanodots for Fluoromagnetic Imaging, Smart Drug Delivery, and Biomolecular Sensing.

Background: Superparamagnetic properties and excitation independence have been incorporated into carbon-decorated manganese ferrite nanodots (MnFe@C) to introduce an economical and safer multimodal agent for use in both T1-T2 MRI and fluorescence-based imaging to replace the conventional highly toxic heavy metal contrast agents.

Methods: The surface conjugation of 8-anilino-1-naphthalenesulfonate (ANS) to MnFe@C nanodots (ANS-MnFe@C) enhances both longitudinal and transverse MRI relaxation, improves fluorescence for optical imaging, and increases protein detection sensitivity, showing higher multimodal efficacy in terms of molar relaxivity, radiant efficiencies, and fluorescence sensitivity compared to MnFe@C.

Results: The band gap energy was determined using Tauc's equation to be 3.

Enhancing Wound Healing with Nanohydrogel-Entrapped Plant Extracts and Nanosilver: An In Vitro Investigation.

Wound healing is a complex process that can be improved through advanced biomedical approaches. Incorporating nanopolymers and plant extracts into wound dressings offers a favorable strategy for promoting tissue repair. Nanopolymers provide a controlled environment for sustained drug release while also protecting the wound from external contaminants.

Enhanced behavioral impact of optimized bupropion-encapsulated bilosomes over traditional niosomes treating depression.

Bupropion (Bpn), an FDA-approved NDRI (norepinephrine-dopamine reuptake inhibitor), poses risks of seizures and liver failure due to its stimulant properties, necessitating the development of alternative formulations. This research aims to develop a Bpn nanoformulation within bilosomal vesicles to enhance therapeutic efficacy at lower doses, using three bile salts, span 20 surfactants, and cholesterol via thin-film hydration. Optimization of bilosomal stability is achieved by trialing various ingredient concentrations, identifying a surfactant-to-cholesterol-to-bile salt ratio of 1.

An evolutionarily conserved function of C-reactive protein is to prevent the formation of amyloid fibrils.

C-reactive protein (CRP) binds to phosphocholine (PCh)-containing substances and subsequently activates the complement system to eliminate the ligand. The PCh-binding function of CRP has been conserved throughout evolution from arthropods to humans. Human CRP, in its structurally altered conformation at acidic pH, also binds to amyloid-β (Aβ) and prevents the formation of Aβ fibrils.

Dosimetric benefits of customised mouth-bite for head neck cancer patients undergoing modern proton therapy - An audit.

Background And Aims: Proton therapy (PRT) for Head Neck Cancer (HNC), in view of the Bragg peak, spares critical structures like oral mucosa better than IMRT. In PRT, mouth-bites, besides immobilising and separating mucosal surfaces, may also negate the end-of-range effect. We retrospectively analysed the details and dosimetric impact of mouth-bites in PRT for HNC.
