Evaluating the efficacy of cavity disinfection using methylene blue dye with 660-nm diode laser on primary molars: An in vivo study.

Background And Objectives: The purpose of this study was to evaluate the antimicrobial activity of methylene blue dye with 660-nm diode laser in cavity disinfection and to compare the total bacterial count in dentinal samples preexcavation, postexcavation, and postdisinfection. The study design was experimental in vivo.

Materials And Methods: Fifteen children aged 5-12 years with 15 primary molars requiring atraumatic restorative treatment (ART) were selected.

Clinical Outcomes and Molecular Profiling of Pancreatic Acinar Cell Carcinoma: A Retrospective Study.

Purpose: Pancreatic acinar cell carcinoma (PACC) is a rare and aggressive form of pancreatic cancer that originates in the acinar cells of the exocrine pancreas. In this study, we aimed to investigate the clinical and molecular characteristics of patients with PACC at our institution.

Methods: This was a retrospective study of patients with PACC seen at Mayo Clinic between 2002 and 2023.

Menopausal hormone therapy: assessing associations with breast and colorectal cancers by familial risk.

Menopausal users of hormone replacement therapy (HRT) are at increased breast cancer risk and decreased colorectal cancer (CRC) risk compared with individuals who have never used HRT, but these opposing associations may differ by familial risk of breast cancer and CRC. We harmonized data from 3 cohorts and generated separate breast cancer and CRC familial risk scores based on cancer family history. We defined moderate or strong family history as a risk score of 0.

Computational investigation of naturally occurring anticancer agents in regulating Hedgehog pathway proteins.

Embryonic development in humans is controlled by the Hedgehog pathway, which becomes inactive in mature tissues. Except for tissue maintenance and healing, activation of this pathway results in tumorigenesis with only a few exceptions. The drugs currently in use have shown no effectiveness in blocking the key proteins responsible for tumorigenesis.

Body mass index at birth and early life and colorectal cancer: A two-sample Mendelian randomization analysis in European and East Asian genetic similarity populations.

Background: Varying obesogenic inherited predisposition in early to later life may differentially impact colorectal cancer (CRC) development. Previous Mendelian randomization (MR) studies, conducted in populations of European genetic similarity, have not observed any significant associations between early life body weight with CRC risk. However, it remains unclear whether body mass index (BMI) at different early lifetime points is causally related with CRC risk in both Europeans and East Asian populations.
