Synthesis and Biological Evaluation of Peripheral HTR2A Antagonists for Colorectal Cancer.

Colorectal cancer is a prevalent and prominent contributor to global cancer-related fatalities with challenges in drug resistance and metastasis. Recent research highlights the potential relationship between serotonin and cancer. 5-Hydroxytryptamine receptor 2A (HTR2A) mRNA expression in colorectal cancer cells was found to be notably elevated compared to that in normal colon cells.

Accuracy of a proposed implant impression technique using abutments and metal framework.

Purpose: This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated.

Material And Methods: Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks.
