From Infection to Tumor: Exploring the Therapeutic Potential of Ciprofloxacin Derivatives as Anticancer Agents.

Ciprofloxacin, a widely used second-generation fluoroquinolone for treating bacterial infections, has recently shown notable anticancer properties. This review explores progress in developing ciprofloxacin derivatives with anticancer properties, emphasizing key structural changes that improve their therapeutic effectiveness by modifying the basic group at position 7, the carboxylic acid group at position 3, or both. It further investigates the mechanisms by which these derivatives fight cancer, such as inducing apoptosis, arresting the cell cycle, inhibiting topoisomerase I and II, preventing tubulin polymerization, suppressing interleukin 6, blocking thymidine phosphorylase, inhibiting multidrug resistance proteins, and hindering angiogenesis.

Conduction system pacing encompassing His bundle pacing (HBP) and left bundle branch area pacing (LBBAP) has recently emerged as a promising alternative to CRT in this group of patients.

Prosthetic Applications of Short Dental Implants in Limited Bone Height Cases: A Review Article.

The decision to rehabilitate insufficient alveolar bone height with short implants is considered an effective treatment. Complicated surgical procedures such as ridge augmentation, vestibuloplasty, and sinus lifting are usually accompanied by high risks such as membrane injury, hemorrhage, nerve affection, and increased time needed for implant treatment with unpredictable healing time. Short dental implants allow for faster treatment and decrease the need for complicated surgeries that are usually associated with standard dental implants, as in all four and all six concepts.
