Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes

open access: yesAdvanced Functional Materials, EarlyView.
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

open access: yesAdvanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

PECULIAR FEATURES IN STRUCTURAL AND FUNCTIONAL HEART VALUES IN PERSONS WITH VARIOUS LEVELS OF BLOOD PRESSURE

open access: yesРоссийский кардиологический журнал, 2002
113 healthy subjects with normal blood pressure and 26 patients with essential hypertension (BP 140-159/90-99 mm Hg) were inspected by echocardiography. All subjects were divided into 5 groups according to the blood pressure (BP) level.

Immunomodulation With Local, Sustained Delivery of Pituitary Adenylate Cyclase Activating Polypeptide Results in Improved Functional Recovery in Stroke‐Injured Mice

open access: yesAdvanced Healthcare Materials, EarlyView.
The tissue and functional benefits are demonstrated with local, sustained delivery of an anti‐inflammatory peptide, pituitary adenylate cyclase‐activating polypeptide (PACAP), for stroke treatment in a mouse model. Prolonged PACAP treatment modulated astrocyte and microglia toward pro‐reparative phenotypes, enhanced neuroprotection and preservation of ...

A Statistical Model for Risk Stratification on the Basis of Left Ventricular Ejection Fraction and Heart-Rate Turbulence [PDF]

open access: yes, 2000
The MPIP data set was used to obtain a model for mortality risk stratification of acute myocardial infarction patients. The predictors heart rate turbulence (HRT) and left-ventricular ejection fraction (LVEF) were employed. HRT was a categorical variable
