Use of the Ion Robot in the Diagnosis of Pulmonary Nodules: Fine Needle Aspiration Versus Cryobiopsy

Diagnostic Cytopathology, EarlyView.
ABSTRACT Background Robotic‐assisted bronchoscopy platforms provide an innovative approach to the sampling of pulmonary nodules. As compared to other technologies, fiber‐optic shape‐sensing instrumentation allows for a more precise, accurate location and sampling of the target lesion with fewer complications.

The anti-cancer effect of retinoic acid signaling in CRC occurs via decreased growth of ALDH+ colon cancer stem cells and increased differentiation of stem cells [PDF]

, 2018
Background: Tumorigenesis is driven by stem cell (SC) overpopulation. BecauseALDH is both a marker for SCs in many tissues and a key enzyme in retinoid acid (RA)signaling, we studied RA signaling in normal and malignant colonic SCs.Hypothesis: RA ...

Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

Epilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...

Assessing Clinical Severity and Prognosis in Adolescents With Anorexia Nervosa and Atypical Anorexia Nervosa Using the Albumin‐Globulin Ratio

European Eating Disorders Review, EarlyView.
ABSTRACT Objective The albumin‐globulin ratio (AGR) is a biochemical marker reflecting nutritional and inflammatory status, with significant prognostic value in chronic conditions. This study examined its association with clinical/biochemical markers in adolescents with anorexia nervosa (AN) and atypical AN (AAN).
