Introduction: Hereditary bleeding disorders stem from the absence or insufficient levels of particular clotting proteins, essential for facilitating coagulation in the clotting cascade. Among the most prevalent are hemophilia A (deficiency of Factor VIII), hemophilia B (deficiency of Factor IX), and von Willebrand disease. Management of pharmacoresistant epilepsy is more difficult in a patient with bleeding disorder due to increased risk of bleeding during surgery.

Article Synopsis
  • Covalent Bruton's tyrosine kinase-inhibitors (cBTK-i) are effective in treating MYD88-mutated Waldenstrom's macroglobulinaemia by inhibiting key signaling pathways that promote tumor growth.* -
  • BTK mutations can lead to treatment resistance by reactivating ERK1/2, which causes increased inflammatory cytokine production and helps BTK wild-type tumor cells survive.* -
  • Pirtobrutinib, a non-covalent BTK-inhibitor, has been shown to successfully block damaging ERK1/2 activity and can overcome resistance in MYD88 lymphoma cells with mutated BTK.*

Estimating the post-mortem interval is still one of the most complex challenges in forensics. In fact, the main tools currently used are burdened by numerous limitations, which sometimes allow the time of death to be placed only within too large time intervals. In recent years, researchers have tried to identify new tools to try to narrow down the interval within which to place the time of death; among these, the analysis of microRNAs seems to be promising.

Piezo proteins have been identified as mechanosensitive ion channels involved in mechanotransduction. Several ion channel dysfunctions may be associated with diseases (including deafness and pain); thus, studying them is critical to understand their role in mechanosensitive disorders and to establish new therapeutic strategies. The current study investigated for the first time the expression patterns of Piezo proteins in zebrafish octavolateralis mechanosensory organs.

Although the postmortem interval estimation still represents one of the main goals of forensic medicine, there are still several limitations that weigh on the methods most used for its determination: for this reason, even today, precisely estimating the postmortem interval remains one of the most important challenges in the forensic pathology field. To try to overcome these limitations, in recent years, numerous studies have been conducted on the potential use of the mRNA degradation time for reaching a more precise post mortem interval (PMI) estimation. An evidence-based systematic review of the literature has been conducted to evaluate the state of the art of the knowledge focusing on the potential correlation between mRNA degradation and PMI estimation.
