The gastric fundus regulates appetite through orexigenic ghrelin-mediated and anorexigenic visceroceptive pathways. Accordingly, endoscopic gastric fundal mucosal ablation (GFMA) may benefit patients with obesity. Ablation not only affects these mechanisms, but similar to what happens after mucosal ablation for other indications (e.g. ESD for tumor removal), it is expected to cause shrinking of the fundus and reduce gastric volume. Another potential target to achieve weight loss is gastric emptying. This is a critical step in digestion that has been found to be more rapid after prolonged exposure to a high-fat diet in both animal and human studies, with rapid emptying also being more common in young people with obesity in some studies. The bariatric endoscopic antral myotomy (BEAM) procedure has been shown to consistently delay gastric emptying without triggering symptoms of gastroparesis and to produce substantial weight loss. Both GFMA and BEAM procedures have the advantages of being minimally invasive, performed completely endoscopic and less costly than surgical alternatives or other known endoscopic techniques like intragastric balloon or endoscopic sleeve gastroplasty.

This study investigates the effects of specific corrective exercises on EMG of masticatory and cervical muscles in individuals with forward head posture. The study's design will be a retrospective, double- blinded, randomized controlled trial. The participants will be randomly allocated to one of two groups: the exercise group and the control group.

Some people have a "gummy smile," where too much gum tissue shows when they smile. Doctors currently diagnose this by hand, using rulers and visual judgment. This study is testing whether a computer program using artificial intelligence (AI) can help identify and measure gummy smiles from photographs, as accurately as expert dentists do it manually. Patients seen at Cairo University's Periodontics and Orthodontics clinics will have photos of their smile taken. Researchers will use these photos to first "teach" the AI program how to recognize and measure a gummy smile. Then, the AI will be tested on a new set of patient photos, and its measurements will be compared to measurements made by expert dentists, to see how closely they match. The goal is to find out whether this AI tool could one day help doctors diagnose gummy smiles more quickly and consistently, which may improve care for patients.
