Helicobacter pylori cells undergo chemotaxis toward several small molecules, called chemo-attractants, including urea produced by the epithelial cells of the stomach. The biophysical mechanisms of chemotaxis are not well understood in H. pylori.
View Article and Find Full Text PDFToday, it is common for medically complex patients who are receiving multiple medications, to seek routine and emergent dental care. It is essential for the practitioner to recognize and comprehend the impact of such medications on the patient's ability to tolerate the planned dental treatment and on dental treatment outcomes. An active appraisal of current literature is essential to stay abreast of emerging findings and understand their treatment implications.

In this review of current literature, we aim to assess safety and efficacy of ureteroscopy (URS) as primary treatment for urolithiasis in the octogenarians.
Materials And Methods: A scoping review of literature according to the PRISMA guidelines was performed, using the relevant search terms.
Article Synopsis
- 3D printing is revolutionizing dentistry by enhancing applications like surgical planning and orthodontic device manufacturing with custom-made models, taking advantage of affordable printers and biocompatible materials.
- The study compares the flexure strength of models created using different 3D printing technologies, including FDM, DLP, and SLA, to assess their suitability as alternatives to traditional plaster models.
- Results indicate that FDM technology yields the strongest models, with a flexure strength of 69.36 MPa, while DLP models demonstrate the weakest performance at 67.47 MPa, highlighting the varying mechanical properties of 3D-printed dental models.
Hydroxyapatite (HAp) with the chemical formula Ca(PO)(OH) is an inorganic material that exhibits morphology and composition similar to those of human bone tissues, making it highly desirable for bone regeneration applications. As one of the most biocompatible materials currently in use, HAp has undergone numerous attempts to enhance its mechanical strength. This research focuses on investigating the influence of magnesium (Mg) incorporation on the structural and mechanical properties of synthesized magnesium-doped hydroxyapatite (MgHAp) samples.
