Identification of Small-Molecule Modulators of FOXO3 Through Virtual Screening.

FOXO3 is integral in regulating numerous genes involved in critical cellular processes such as apoptosis, oxidative damage protection, cell growth, and cancer. Consequently, modulating FOXO3 activity holds significant potential for applications in cancer treatment and cellular aging. A promising approach involves identifying small-molecule modulators that can either enhance or inhibit FOXO3's DNA-binding capability.

Bidirectional transfer of a small membrane-impermeable molecule between the Caenorhabditis elegans intestine and germline.

The extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) is a positive regulator of cell proliferation often upregulated in cancer. Its Caenorhabditis elegans ortholog MPK-1 stimulates germline stem cell (GSC) proliferation nonautonomously from the intestine or somatic gonad. How MPK-1 can perform this task from either of these two tissues however remains unclear.

Urine biomarkers can predict prostate cancer and PI-RADS score prior to biopsy.

Prostate-Specific Antigen (PSA) based screening of prostate cancer (PCa) needs refinement. The aim of this study was the identification of urinary biomarkers to predict the Prostate Imaging-Reporting and Data System (PI-RADS) score and the presence of PCa prior to prostate biopsy. Urine samples from patients with elevated PSA were collected prior to prostate biopsy (cohort = 99).

Spatial Distribution of Recurrence and Long-Term Toxicity Following Dose Escalation to the Dominant Intra-Prostatic Nodule for Intermediate-High-Risk Prostate Cancer: Insights from a Phase I/II Study.

We investigated spatial patterns between primary and recurrent tumor sites and assessed long-term toxicity after dose escalation stereotactic body radiation therapy (SBRT) to the dominant intra-prostatic nodule (DIN). In 33 patients with intermediate-high-risk prostate cancer (PCa), doses up to 50 Gy were administered to the DIN. Recurrence sites were determined and compared to the original tumor development sites through multiparametric MRI and Ga-labeled prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (Ga-PSMA-PET/CT) images.

[Contribution of technological aids to the extraction of orbital foreign bodies].

Background: Removal of orbital foreign bodies is a surgical challenge. The purpose of this study is to report our experience in the removal of orbital foreign bodies and to evaluate the usefulness of various technological aids in their removal.

Materials And Methods: We conducted a single-center retrospective study at Nice University Hospital (France) from January 2017 to December 2023.
