Threshold of microvascular occlusion: injury size defines the thrombosis scenario [PDF]
, 2014 Damage to the blood vessel triggers formation of a hemostatic plug, which is meant to prevent bleeding, yet the same phenomenon may result in a total blockade of a blood vessel by a thrombus, causing severe medical conditions. Here, we show that the physical interplay between platelet adhesion and hemodynamics in a microchannel manifests in a critical ...

Supervised Contrastive Learning to Classify Paranasal Anomalies in the Maxillary Sinus [PDF]
arXiv, 2022 Using deep learning techniques, anomalies in the paranasal sinus system can be detected automatically in MRI images and can be further analyzed and classified based on their volume, shape and other parameters like local contrast. However due to limited training data, traditional supervised learning methods often fail to generalize.

Clinical Case Reports, Volume 13, Issue 6, June 2025.ABSTRACT Although infective endocarditis (IE) during pregnancy is rare, it is associated with high maternal and fetal mortality rates. Educating pregnant women on infection prevention is essential. If IE occurs, multidisciplinary collaboration is important to determine an optimal strategy for childbirth and surgery in its successful management.

Nasal irrigation delivery in three post-FESS models from a squeeze-bottle using CFD [PDF]
arXiv, 2022 Purpose: Nasal saline irrigation is highly recommended in patients following functional endoscopic sinus surgery (FESS) to aid the postoperative recovery. Post-FESS patients have significantly altered anatomy leading to markedly different flow dynamics from those found in pre-op or non-diseased airways, resulting in unknown flow dynamics. Methods: This

ESC Heart Failure, Volume 12, Issue 3, Page 2066-2076, June 2025.Abstract Background Heart failure (HF) is a risk factor for ischemic stroke. Cognitive impairment is very common in HF and stroke patients. Patients with HF have higher risk of developing dementia. However, there are limited studies investigating the characteristics, in‐hospital mortality and complications of stroke patients with both HF and dementia ...
