deficiency modulates the stromal environment in the pretumorigenic rat mammary gland.

Background: Neurofibromin, coded by the tumor suppressor gene, is the main negative regulator of the RAS pathway and is frequently mutated in various cancers. Women with Neurofibromatosis Type I (NF1)-a tumor predisposition syndrome caused by a germline mutation-have an increased risk of developing aggressive breast cancer with poorer prognosis. The mechanism by which mutations lead to breast cancer tumorigenesis is not well understood.

Opioid Use in Patients With Cervical Cancer at a Tertiary Academic Medical Center.

Background/aim: Opioids are a common treatment for cancer-related pain and information is limited on the rates of opioid use for cervical cancer patients. This study aimed to analyze outpatient opioid use and various predictors among patients with cervical cancer at a tertiary academic medical center.

Patients And Methods: Data from patients with cervical cancer receiving treatment at a single institution, from August 2019 to July 2022, were retrospectively collected.

The Effectiveness of Hot Bead Sterilization in Maintaining Sterile Surgical Instrument Tips across Sequential Mouse Surgeries.

One strategy commonly employed for rodent surgeries is a "tips-only" surgical technique, which restricts the surgeon to using only the sterile working ends of the surgical instruments to manipulate the surgical field and sterilizes instrument tips with a hot bead sterilizer between consecutive rodents. Despite the common use of the "tips-only" technique, research is lacking on the number of sequential surgeries for which the same set of hot bead-sterilized instruments can be used before introducing bacterial contamination. We performed serial mouse surgeries using the "tips-only" technique under 3 different conditions (aseptic, fur contamination, or cecal contamination) and assessed aerobic bacterial growth before and after each round of hot bead sterilization.
