Pituitary Adenoma Segmentation [PDF]
Sellar tumors are approximately 10-15% among all intracranial neoplasms. The most common sellar lesion is the pituitary adenoma. Manual segmentation is a time-consuming process that can be shortened by using adequate algorithms. In this contribution, we present a segmentation method for pituitary adenoma.

ABSTRACT Pathogenic germline variants in the APC gene result in familial adenomatous polyposis (FAP) which can escalate into colon cancer. Standard clinical testing failed to identify pathogenic variants in a 4‐generation FAP family. We identified and assessed co‐segregation of a 5′ untranslated region (UTR) variant, NM_001127511.3 (APC) c.‐40G>A ...

Cohesins: Crossroad Between Cornelia de Lange Spectrum and Cancer Predisposition
ABSTRACT The cohesin complex plays crucial roles in DNA repair, chromatid separation, and gene transcription regulation. Pathogenic variants in cohesins or dysfunctional transcriptional regulators lead to cohesinopathies, a broader group of disorders including Cornelia de Lange Spectrum (CdLSp), for which the prevalence of cancer cases remains unclear.

Gut microbiota‐stem cell niche crosstalk: A new territory for maintaining intestinal homeostasis
Intestinal stem cells (ISCs) are protected by their niche and are regulated by Wnt, bone morphogenetic protein, and Notch. ISCs and their relationship with intestinal microbiota provide a feasible pathway to alleviate intestinal diseases. Diverse bacteria‐related postbiotics regulate ISCs and maintain their homeostasis.
