Impact of antiphospholipid syndrome on placenta and uterine NK cell function: insights from a mouse model.

Antiphospholipid syndrome (APS) is associated with recurrent pregnancy morbidity, yet the underlying mechanisms remain elusive. We performed multifaceted characterization of the biological and transcriptomic signatures of mouse placenta and uterine natural killer (uNK) cells in APS. Histological analysis of APS placentas unveiled placental abnormalities, including disturbed angiogenesis, occasional necrotic areas, fibrin deposition, and nucleated red blood cell enrichment.

Complexity of synovial fluid-derived monocyte-macrophage-lineage cells in knee osteoarthritis.

Synovial fluid (SF)-derived monocyte-macrophage (MON-Mϕ)-lineage cells in knee osteoarthritis (KOA) remain poorly understood. We analyzed SF samples from 420 patients with KOA with effusion. The MON-Mϕ cells accounted for 47.

[Ectopic biliary varices as a cause of portal biliopathy and mechanical jaundice syndrome].

The authors consider ectopic biliary varices as a possible cause of portal biliopathy in extrahepatic portal hypertension. The main diagnostic methods including ultrasound CT, MRI, endoscopic ultrasonography, cholangioscopy, difficulties of differential diagnosis and clinical manifestations of portal biliopathy are presented. Various treatment options including portosystemic shunting and endoscopic biliary decompression are discussed.

Infection of Human Macrophage-Like Cells by African Swine Fever Virus.

Background: The African swine fever (ASF) virus (ASFV) and ASF-like viral sequences were identified in human samples and sewage as well as in different water environments. Pigs regularly experience infections by the ASFV. The considerable stability of the virus in the environment suggests that there is ongoing and long-term contact between humans and the ASFV.

Determining Thrombogenicity: Using a Modified Thrombin Generation Assay to Detect the Level of Thrombotic Event Risk in Lupus Anticoagulant-Positive Patients.

The aim of this study was to determine the thrombogenicity of lupus anticoagulant (LA) antibodies using a modified thrombin generation assay (TGA) with the addition of activated protein C (APC) in a group of 85 patients with LA-positive samples. Of these, 58 patients had clinical manifestations of antiphospholipid syndrome (APS) according to the Sydney criteria classification, i.e.
