AI Article Synopsis

  • The study examines how human plasma fibrinogen (HPF) adsorbs on various treated titanium surfaces, including polished and titanium carbide coatings.
  • An innovative diffractive optical element (DOE) sensor is used to monitor changes in permittivity and optical roughness when exposed to both the background electrolyte and HPF.
  • Results indicate a correlation between the transmitted light and the thickness of the HPF layer, providing insights into the dynamics of fibrinogen adsorption at the nano-scale on different titanium surfaces.

Article Abstract

Adsorption of human plasma fibrinogen (HPF) on 6 differently treated titanium samples (polished, polished and etched, and 4 titanium carbide coatings samples produced by using plasma-enhanced chemical vapour deposition (PECVD) method) is investigated by using diffractive optical element (DOE) sensor. Permittivity (susceptibility) change and fluctuation in optical roughness (R(opt)) of treated titanium surface in the presence of background electrolyte without and with HPF molecules are sensed by using DOE sensor and optical ellipsometry. Correlation between transmitted light and thickness of molecule layer was found. The findings allow to sense temporal organization and severity of adsorption of nano-scale HPF molecules on polished, on polished and etched, and on titanium carbide surface.

Emodin (ED), as a traditional Chinese medicine, possesses a variety of biological activities and is also one of natural sonosensitizer. Whether emodin could react with titanium dioxide to enhance the sonodynamic activity for safely treating osteomyelitis remains to be explored. Hence, an ED-conjugated Mn-doped titanium dioxide (TOM) nanorod array is designed and prepared on titanium to eliminate bacterial infections under ultrasound (US) treatment.

Objective: CSF leaks are a significant source of patient morbidity following intradural spine surgeries. Watertight dural closure is crucial during these procedures to minimize the risk of a CSF leak. This study reports postoperative outcomes and changes in patient management after switching to penetrating titanium clips for dural closure in a large cohort of pediatric patients receiving a tethered cord release (TCR) or a selective dorsal rhizotomy (SDR).

This case report describes the reconstruction of a rostral maxillary defect by two custom-made titanium implants following a rostral partial maxillectomy for treatment of squamous cell carcinoma (SCC) in a seven-year-old dog. An incisional biopsy and CT scan were performed to establish the diagnosis, to plan possible surgery, and to assess the margins of the tumour. The patient had no radiographic signs of metastasis at the time of diagnosis.

Background: Anatomically formed healing abutments were suggested in literature to address many of the issues associated with immediate posterior implant insertion such as large extraction sockets that are extremely hard to seal without reflecting the mucoperiosteal flap, extraction sockets anatomy that are not suitable for regular healing abutment placement, and potentially high occlusal stresses when planning a temporary implant supported prothesis to improve the conditioning of supra implant tissue architecture and the emergence profile of the implant supported restorations.

Purpose: To clinically evaluate the peri-implant soft tissue profile of single posterior implant retained restorations and to assess patient related outcomes of the implant restorations that were conditioned immediately by CAD-CAM socket sealing abutments (SSA) versus those conditioned by Titanium (Ti) standard healing abutments (SHA).

Methods: Twenty participants received twenty-two single maxillary immediate implants after flapless minimally invasive tooth extraction and 3D guided implant placement in the posterior area (premolar and molar) and allocated randomly into two groups (n = 11), the intervention group: patients received PEEK SSA and the control group: the patients received Ti SHA.

Cancer remains a leading cause of mortality, with aggressive, treatment-resistant tumors posing significant challenges. Current combination therapies and imaging approaches often fail due to disparate pharmacokinetics and difficulties correlating drug delivery with therapeutic response. In this study, we developed radionuclide-activatable theranostic nanoparticles (NPs) comprising folate receptor-targeted bimetallic organo-nanoparticles (Gd-Ti-FA-TA NPs).
