Unveiling cell-type-specific microRNA networks through alternative polyadenylation in glioblastoma.

Background: Glioblastoma multiforme (GBM) is characterized by its cellular complexity, with a microenvironment consisting of diverse cell types, including oligodendrocyte precursor cells (OPCs) and neoplastic CD133 + radial glia-like cells. This study focuses on exploring the distinct cellular transitions in GBM, emphasizing the role of alternative polyadenylation (APA) in modulating microRNA-binding and post-transcriptional regulation.

Results: Our research identified unique APA profiles that signify the transitional phases between neoplastic cells and OPCs, underscoring the importance of APA in cellular identity and transformation in GBM.

The diagnostic value of serum hepcidin in acute appendicitis.

Background: Acute appendicitis (AA) is the primary cause of acute abdomen in patients presenting to the emergency department with abdominal pain. Limited studies have explored the relationship between serum hepcidin levels and AA. This study aimed to measure serum hepcidin levels in patients undergoing surgery with a preliminary diagnosis of AA and to assess whether these levels can serve as a biochemical marker for diagnosing AA.

Point-of-care testing, near-patient testing and patient self-testing: warning points.

Point-of-care testing (POCT), near-patient testing (NPT) and patient self-tests (PST) are diagnostic examinations performed at the time and place of patient care. While POCT and NPT are performed and analyzed by medical professionals, PST are based on samples and parameters directly collected and analyzed by lay users. These tests are spreading both in high income countries and in low to middle income countries as they are expected to improve healthcare efficiency and equity, by saving resources, releasing pressure from hospitals and reducing logistical barriers.

Palladium-Catalyzed Regioselective Synthesis of 2-SF -Indenols and Further Derivatizations.

A palladium-catalyzed synthesis of 2-SF -indenols has been developed by reacting commercially available boronic acid derivatives and readily accessible SF -alkynes. The present methodology is fully regioselective thanks to the intrinsic polarization of SF -alkynes. A selection of downstream functionalizations has been performed to highlight the versatility of 2-SF -indenols and indenones as platforms for the design of more complex SF -containing molecules.
