Background: Several studies have reported the efficiency of immediate loading techniques.
Purpose: The aim of this multicenter prospective study was to evaluate the clinical efficiency of the one-piece screw (OPS) implants used by general dentists.
Materials And Methods: A total of 272 patients were treated with 533 implants at five dental clinics by five general dentists. Some implants were provided with provisional restoration. Implants in partially edentulous spaces were splinted with acryl, composite, and intraoral welding. The implant survival rates, bone resorption, plaque accumulation, and soft tissue health were evaluated after 3, 6, and 12 months. The final restorations were cemented in the maxilla after 6 months and in the mandible after 3 months.
Results: Twelve implants failed (98% survival rate) after 12 months. None of the splinted implants failed during the follow-ups. There were five failures in unsplinted partial cases. The average amounts of bone loss around the implants were 0.40 ± 0.35 mm, 0.56 ± 0.41 mm, and 0.59 ± 0.41 mm after 3, 6, and 12 months, respectively. Visible plaque was registered in 18% of the implants, and bleeding on probing was observed in 17% of the implants after 12 months.
Conclusions: High survival rates and favorable host tissue responses support the clinical performance of OPS implants. This study demonstrated that one-piece implants can be efficiently used by well-trained general dentists.

Purpose: To investigate the effect of Rho-associated protein kinase (ROCK) inhibitor Y27632 on bioenergetic capacity and resilience of corneal endothelial cells (CECs) under metabolic stress.
Methods: Bovine CECs (BCECs) were treated with Y27632 and subjected to bioenergetic profiling using the Seahorse XFp Analyzer. The effects on adenosine triphosphate (ATP) production through oxidative phosphorylation and glycolysis were measured.

Importance: Given the favorable overall prognosis of human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) and the morbidity of increased adjuvant therapy associated with positive surgical margins, large-scale studies on the accuracy of frozen sections in predicting final surgical margin status in HPV-related OPSCC are imperative. Final surgical margin status is the definitive assessment of tumor clearance as determined through surgeon-pathologist collaboration based on permanent analysis of frozen section margins, main specimens, and supplemental resections.
Objectives: To assess the accuracy and testing properties of intraoperative frozen section histology (IFSH) in assessing final surgical margin status in patients undergoing transoral surgery for HPV-related OPSCC.

Photosynthetic microbes have evolved and successfully adapted to the ever-changing environmental conditions in complex microhabitats throughout almost all ecosystems on Earth. In the absence of light, they can sustain their biological functionalities through aerobic respiration, and even in anoxic conditions through anaerobic metabolic activity. For a suspension of photosynthetic microbes in an anaerobic environment, individual cellular motility is directly controlled by its photosynthetic activity, i.

Background: Neoadjuvant therapy is recommended for treating resectable pancreatic ductal adenocarcinoma (PDAC); however, its appropriate use in patients with resectable PDAC remains debatable.
Objective: This study aimed to identify independent poor prognostic factors and evaluate the clinical significance of neoadjuvant therapy in patients with resectable PDAC.
Methods: We retrospectively reviewed consecutive patients diagnosed with resectable PDAC at our institute between January 2003 and December 2022.

Background: Three dimensional (3D) cell cultures can be effectively used for drug discovery and development but there are still challenges in their general application to high-throughput screening. In this study, we developed a novel high-throughput chemotherapeutic 3D drug screening system for gastric cancer, named 'Cure-GA', to discover clinically applicable anticancer drugs and predict therapeutic responses.
Methods: Primary cancer cells were isolated from 143 fresh surgical specimens by enzymatic treatment.
