Paratesticular Extramedullary Hematopoiesis in Children
Archives of Pathology & Laboratory Medicine, 2023 Context.— Extramedullary hematopoiesis (EMH) is an uncommon occurrence, usually associated with hematologic disorders, but it rarely presents as an isolated finding. Objective.— To determine the frequency, immunomorphologic features, and ...

Extramedullary Hematopoiesis: An Unusual Finding in Subdural Hematomas
Case Reports in Pathology, 2011 We present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture.

The Role of MCPIP1 in Macrophage Polarization and Cardiac Function Post‐Myocardial Infarction
Advanced Science, EarlyView.Following myocardial infarction, MCPIP1 deficiency in macrophages triggers ferroptosis, driving proinflammatory M1 dominance over reparative M2 phenotypes. This imbalance amplifies splenic monocyte release and sustains cardiac inflammation. Concurrently, excessive inflammatory mediators and insufficient TGF‐β impair fibroblast activation, delaying ...

Cancer Management and Research, 2018 Extramedullary hematopoiesis (EMH) usually occurs in hematological disease, but more rarely develops in cases of malignant solid tumors. Due to its features on computed tomography (CT) and magnetic resonance imaging (MRI) that are atypical, EMH in tumor ...

Animal Models and Experimental Medicine, EarlyView.We successfully constructed CAST/EiJ mice models infected with low‐dose vaccinia virus (VACV‐L), high‐dose VACV (VACV‐H), and mpox virus (MPXV), demonstrating that VACV‐L and MPXV infections induced splenomegaly in mice, and VACV‐H infection caused mortality in mice.

Expert Perspective: Diagnosis and Treatment of Castleman Disease
Arthritis &Rheumatology, Accepted Article.Summary Castleman disease (CD) is a major diagnostic challenge for Rheumatologists. Unicentric CD (UCD) involves one enlarged lymph node region whereas multicentric CD (MCD) involves multiple enlarged lymph node regions. Both UCD and MCD may exhibit a wide range of symptoms that overlap with other immune‐mediated conditions.

Journal of Clinical Investigation, 2017 Extramedullary hematopoiesis (EMH) is induced during pregnancy to support rapid expansion of maternal blood volume. EMH activation requires hematopoietic stem cell (HSC) proliferation and mobilization, processes that depend upon estrogen receptor α (ERα)

Positive periodic solutions for systems of impulsive delay differential equations [PDF]
arXiv, 2021 A class of periodic differential $n$-dimensional systems with patch structure with (possibly infinite) delay and nonlinear impulses is considered. These systems incorporate very general nonlinearities and impulses whose signs may vary. Criteria for the existence of at least one positive periodic solution are presented, extending and improving previous ...
