Escape from TGF-β-induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells.

Transforming growth factor-β (TGF-β) signaling and cellular senescence are key hallmarks of hepatocellular carcinoma (HCC) pathogenesis. Despite provoking senescence-associated growth arrest in epithelial HCC cells, elevated TGF-β activity paradoxically correlates with increased aggressiveness and poor prognosis in advanced tumors. Whether the transition between these dichotomous functions involves modulation of the senescence phenotype during disease progression remains elusive.

The Predictive Power of Intraoperative Surgical Apgar Scores in Foreseeing Renal Function after Radical Nephrectomy.

Introduction: This study was conducted to evaluate the predictive power of the Surgical Apgar Score (SAS) based on surgical blood loss, the lowest intraoperative heart rate and mean arterial pressure in foreseeing short- and long-term effects of radical nephrectomy (RN) on renal function.

Methods: A prospective investigation was conducted on 111 patients who underwent RN for kidney tumors at a tertiary hospital between 2016 and 2019. The SAS and age-adjusted Charlson Comorbidity Index (CCI) scores were calculated in relation to glomerular filtration rates (GFR) changes on postoperative 1st day, 3rd and 12th months.

The role of microglia in the prion-like transmission of protein aggregates in neurodegeneration.

Numerous neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis share a neuropathological hallmark: aberrant protein aggregation in the CNS. Microglia, the brain's innate immune cells, also play a pivotal role in the pathogenesis of these disorders. Multiple studies indicate that these pathological aggregates can propagate throughout the brain in a prion-like manner.

Is Myopenia or Myosteatosis Clinically Relevant in Systemic Sclerosis? Skeletal Muscle Assessment Using Computed Tomography.

Objectives: Systemic sclerosis (SSc) is a chronic autoimmune disease characterized by fibrosis, vascular damage, and immune dysregulation, often leading to muscle abnormalities. This study aimed to evaluate the prevalence of myopenia and myosteatosis in SSc patients using computed tomography (CT) and their associations with clinical features, including lung disease and esophageal dilatation.

Materials And Methods: SSc patients followed at Gazi University Rheumatology Clinic (2000-2024) who had thoracic CT imaging were included.

The Effectiveness of Pelvic Ultrasonography Findings in Diagnosing Precocious Puberty.

Objective: Gonadotropin-releasing hormone (GnRH) stimulation testing is the gold standard for distinguishing central precocious puberty (CPP) from premature thelarche (PT). Due to the limitations of this test, previous studies have elucidated the clinical and laboratory factors that predict CPP. This study explored the diagnostic importance of pelvic ultrasound in girls with CPP.
