Background: The continuous development in digital prosthodontics allowed the customization of attachments and retentive inserts which offers an easy and cheap solution for regular maintenance of locator overdentures during daily practice. The present study compared the change in retention values of the fully digitally manufactured custom-made locator attachment retentive insert with the ready-made ones after insertion, removal, and masticatory cycles.
Methods: A complete denture was constructed over a mandibular edentulous epoxy model.

The prevalence of nanoplastics in water has led to significant environmental and health concerns, yet effective and scalable strategies for mitigating this contamination remain limited. Here, we report a straightforward, efficient, and scalable approach to degrade nanoplastics in water using enzyme-loaded hydrogel granules with an interconnected porous structure and adjustable properties. These porous hydrogels were synthesized via a polymerization-induced phase separation method, allowing easy scaling-up.

In recent years, despite significant advances in preconcentration and preparation techniques that have led to efficient recovery and accurate measurement of target compounds. There is still a need to develop adsorbents with unique and efficient features such as high pore volume and surface area, reactivity, easy synthesis, low toxicity, and compatibility with the environment, which increase the adsorption capacity and increase extraction efficiency. Semiconductor nanocrystals called quantum dots (QDs) with a size of less than 10 nm are three-dimensional nanoparticles with a spherical, rod, or disc structure that have significant potential in extraction as adsorbents due to their excellent properties such as low toxicity, reactivity, environmental friendliness, and hydrophilic and hydrophobic interactions.

As emerging therapeutic strategies for aging and age-associated diseases, various biochemical approaches have been developed to selectively remove senescent cells, but how physical stimulus influences senescent cells and its possible application in senolytic therapy has not been reported yet. Here we developed a physical method to selectively stimulate senescent cells via low-intensity pulsed ultrasound (LIPUS) treatment. LIPUS stimulation did not affect the cell cycle, but selectively enhanced secretion of specific cytokines in senescent cells, known as the senescence-associated secretory phenotype (SASP), resulting in enhanced migration of monocytes/macrophages and upregulation of phagocytosis of senescent cells by M1 macrophage.

Coagulation process is a well-known process that has been used in water treatment for many years. Coagulation process shows the treatment efficiency in terms of turbidity and suspended solids removal. However, despite all these good results, coagulant selection is not an easy task because a coagulant can effectively remove suspended solids but at the same time increase conductivity or coagulants can significantly increase chemical sludge production.
