The Role of Cardiac Troponins in Postmortem Diagnosis of Myocardial Ischemia: A Systematic Review.

Postmortem diagnosis of myocardial ischemia remains a challenge in forensic pathology, as traditional methods like autopsy and histology may not always provide conclusive results. Cardiac troponins, specifically cTnI and cTnT, are well-established biomarkers for myocardial injury in living patients, but their role in postmortem ischemia diagnosis is still under investigation. This systematic review aims to evaluate the role of troponins in diagnosing myocardial ischemia in postmortem cases, focusing on the diagnostic accuracy, sample types, and the influence of the postmortem interval (PMI).

Atmospheric Exposure Triggers Light-Induced Degradation in 2D Lead-Halide Perovskites.

Quasi-2D perovskites have been pivotal in recent efforts to stabilize perovskite solar cells. Despite the stability boost provided when these materials are introduced in perovskite solar cells, little is known about the intrinsic light and environmental stability of quasi-2D perovskites. In this study, we characterize the photostability of exfoliated quasi-2D perovskite single crystals in air using photoluminescence, infrared, X-ray fluorescence, and energy-dispersive X-ray spectroscopy.

Faricimab was administered with a loading dose of four 4-weekly injections, followed by a treat-and-extend regimen.

PARP enzymes and mono-ADP-ribosylation: advancing the connection from interferon-signalling to cancer biology.

ADP-ribosyltransferases of the PARP family encompass a group of enzymes with variegated regulatory functions in cells, ranging from DNA damage repair to the control of cell-cycle progression and immune response. Over the years, this knowledge has led to the use of PARP1/2 inhibitors as mainstay pharmaceutical strategies for the treatment of ovarian, pancreatic, prostate and breast cancers, holding mutations in genes encoding for proteins involved in the DNA repair mechanisms (synthetic lethality). Meanwhile, the last decade has witnessed significant progress in comprehending cellular pathways regulated by mono-ADP-ribosylation, with a huge effort in the development of novel selective compounds to inhibit those PARPs endowed with mono-ADP-ribosylation activity.

Intertumoral lineage diversity and immunosuppressive transcriptional programs in well-differentiated gastroenteropancreatic neuroendocrine tumors.

Neuroendocrine tumors (NETs) are rare cancers that most often arise in the gastrointestinal tract and pancreas. The fundamental mechanisms driving gastroenteropancreatic (GEP)-NET growth remain incompletely elucidated; however, the heterogeneous clinical behavior of GEP-NETs suggests that both cellular lineage dynamics and tumor microenvironment influence tumor pathophysiology. Here, we investigated the single-cell transcriptomes of tumor and immune cells from patients with gastroenteropancreatic NETs.
