Background: A study of patients with spontaneous intracerebral hemorrhage (SIH) found a higher content of Fas ligand in the perihematomic brain area compared to healthy brain areas. The objective of this study was to analyze whether blood soluble Fas ligand (sFasL) concentrations could be used to estimate the prognosis of SIH patients.
Methods: Observational and prospective study performed in five Spanish Intensive Care Units. Patients with evere supratentorial SIH, defined as Glasgow Coma Scale (GCS) <9, were included. Serum sFasL levels were determined at the time of diagnosis of severe SIH. Mortality at 30 days was the end-point study.
Results: Surviving SIH patients ( = 41) compared to nonsurvivors (n = 38) showed lower serum sFasL levels ( < 0.001). The area under curve of mortality prediction for serum sFasL levels was 0.79 (95% CI = 0.70-0.89; < 0.001). Multiple logistic regression analysis found an association of serum sFasL concentrations with 30-day mortality (ORo = 1,034; 95% CI = 1,010-1,058; = 0,006) after controlling for midline shift, early hematoma evacuation, and intracerebral hemorrhage score.
Conclusions: The capability of serum sFasL to predict SIH patient mortality is the main novel finding of our study.

Acute injury and secondary injury caused by traumatic brain injury (TBI) seriously threaten the health of patients. The purpose of this study was to investigate the role of β-Asarone in TBI-induced neuroinflammation and injury. In this work, the effects of β-Asarone on nerve injury and neuronal apoptosis were investigated in mice with TBI by controlled cortical impingement.

Background/objectives: Perillyl alcohol (POH), a plant-derived compound, has demonstrated anti-tumor activity across various human cancers. Understanding the regulatory pathways through which POH exerts its effects is crucial for identifying new therapeutic opportunities and exploring potential drug repositioning strategies. Therefore, this scoping review aims to provide a comprehensive overview of the metabolic and regulatory pathways involved in the anticancer effects of POH, based on in vitro evidence.

Introduction: Recent investigations have highlighted the intratumoral administration of Toll-like receptor (TLR) ligands as a promising approach to initiate localized immune responses and enhance antitumor immunity. However, the clinical application of these ligands is limited by their rapid dissemination from the tumor microenvironment, raising concerns about reduced effectiveness and systemic toxicity.
Methods: To address these challenges, our study focused on the intratumoral delivery of mRNA encoding UNE-C1, a TLR2/6 ligand known for its efficacy and low toxicity profile.
Background: B-cell-specific Moloney murine leukemia virus integration site 1 (BMI1) and Fas ligand (FasL) are two critical stemness genes believed to play a role in the development of colorectal cancer (CRC). This study aimed to investigate the expression levels of these genes in primary CRC tumors to assess their correlation with cancer progression and prognosis.
Methods: The relative expression levels of BMI1 and FasL were analyzed using real-time polymerase chain reaction in 100 primary CRC tumor samples along with paired adjacent non-cancerous tissues.

Article Synopsis
- Activation of Fas in adipocytes inhibits the browning process, potentially leading to increased body weight gain in mice, and its expression correlates with higher BMI in humans.
- The study found that Fas activation decreases energy expenditure through reduced protein levels of p53, a tumor suppressor, in adipocytes.
- In humans, higher p53 levels in subcutaneous and visceral white adipose tissue were linked to increased BMI, while higher levels in visceral fat were associated with lower insulin sensitivity.
