Spontaneous Interatrial Hematoma: Still an Unresolved Critical Conundrum.

Spontaneous interatrial hematoma is a rare clinical entity leading to the obliteration of the left atrial cavity and causing haemodynamic compromise, necessitating immediate surgical intervention. Herein, we report a patient with acute chest pain with normal coronaries and echocardiographic evidence of left atrial mass. The investigations revealed the mass to be a thrombus rather than tumour.

LRRC8 complexes are adenosine nucleotide release channels regulating platelet activation and arterial thrombosis.

Platelet shape and volume changes are early mechanical events contributing to platelet activation and thrombosis. Here, we identify single-nucleotide polymorphisms in Leucine-Rich Repeat Containing 8 (LRRC8) protein subunits that form the Volume-Regulated Anion Channel (VRAC) which are independently associated with altered mean platelet volume. LRRC8A is required for functional VRAC in megakaryocytes (MKs) and regulates platelet volume, adhesion, and agonist-stimulated activation, aggregation, ATP secretion and calcium mobilization.

Dlk1 is a novel adrenocortical stem/progenitor cell marker that predicts malignancy in adrenocortical carcinoma.

Disruption of processes involved in tissue development and homeostatic self-renewal is increasingly implicated in cancer initiation, progression, and recurrence. The adrenal cortex is a dynamic tissue that undergoes life-long turnover. Here, using genetic fate mapping and murine adrenocortical carcinoma (ACC) models, we have identified a population of adrenocortical stem cells that express delta-like non-canonical Notch ligand 1 (DLK1).
