Article Abstract
Background: A novel type of implant (Straumann® BLX implant) has been developed for certain stability from the mechanical and biological aspects and is expected for the implant placement in atrophic maxilla with sinus floor elevation (SFE).
Purpose: The aim of this study was to evaluate the primary stability in the implants with different macrodesigns in an SFE simulated model. Primary stabilities defined as maximum insertion torque (MIT) and implant stability quotient (ISQ) were compared between this novel type of implant and other types.
Materials And Methods: Five types of Straumann® 10 mm length implants (Standard Plus; SP, Tapered Effect; TE, Bone Level; BL, Bone Level Tapered; BLT and BLX) and two types of Straumann® 6 mm length implants (SP short, BLX short) were used in this study. Each implant was inserted through 5 mm-thick porcine iliac crest blocks (an SFE simulated model). Primary stability was evaluated by using MIT and ISQ.
Results: The mean value of MIT for BLX group showed significantly higher values than SP, BL (p < 0.01), and TE (p < 0.05) groups. The mean value of ISQ for BLX group was significantly higher than the other groups (p < 0.01). The mean value of MIT and ISQ for BLX and BLX short group were significantly higher than those for SP and SP short group (p < 0.01).
Conclusions: In an SFE simulated ex vivo model, BLX group showed the highest values. These results suggest that implant selection can play a crucial role in the achievement of primary stability during SFE and simultaneous implant placement.

Circulating tumor cells (CTCs) carry intact tumor molecular information, making them invaluable for personalized cancer monitoring. However, conventional capture methods, relying on passive diffusion, suffer from low efficiency due to insufficient collision frequency, severely limiting clinical utility. Herein, a magnetic micromotor-functionalized DNA-array hunter (MMDA hunter) is developed by integrating enzyme-propelled micromotors, magnetic nanoparticles, and nucleic acid aptamers into distinct functional partitions of a DNA tile self-assembly structure.

Anastrepha obliqua, a neotropical pest widely distributed in the Americas, attacks mango and other tropical fruits. In Mexico, it is controlled through integrated pest management, using the Sterile Insect Technique (SIT) as a main component. The applicability of SIT is significantly improved with the use of genetic sexing strains (GSS) that allow the possibility to release exclusively sterile males, the primary component of the technique.

Peritoneal dialysis (PD) and hemodialysis (HD) are the two primary renal replacement therapies for patients with end-stage renal disease (ESRD). While PD is an effective and convenient modality, long-term use can lead to ultrafiltration failure, recurrent peritonitis, and progressive structural alterations in the peritoneal membrane, necessitating a transition to HD. In recent years, rather than a complete transition, the combined use of PD and HD has emerged as a viable alternative, offering potential advantages for selected patient populations.

Background: Improved cancer survival rates have highlighted second primary malignancies (SPMs), with the thyroid gland being one of the most common organs developing SPMs in cancer survivors. Second primary papillary thyroid carcinoma (2-PTC) is the predominant type, yet it remains poorly understood. This study aims to delineate the clinicopathological features and survival outcomes of 2-PTC and assess the efficacy of postoperative radioactive iodine therapy (post-RAIT) in reducing mortality risks in intermediate-risk 2-PTC patients.

Background: Aflatoxin B1 (AFB1) stands among the most toxic naturally occurring substances, with its acute toxicity characterized by the induction of acute hepatic necrosis, hemorrhage, and even fatal outcomes, thereby posing a profound threat to human health. Contamination of AFB1 in food commodities can arise at multiple stages throughout the production cycle, including cultivation, storage, and processing. This contamination cascade permeates the entire food supply chain, encompassing primary agricultural products as well as a diverse range of processed food items.
