4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...

An Injection‐Molded Modified Silicone Rubber for Cancer‐on‐Chip Applications
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This study describes the characterization and application of an injection‐molded functionalized PDMS fluidic insert for the commercially available Micronit system. Modified PDMS can accommodate cell culture and is able to covalently bind proteins for long‐lasting coatings under flow‐conditions.

Astaxanthin increases choroidal blood flow velocity
Graefe's Archive for Clinical and Experimental Ophthalmology, 2011Previous studies have reported that astaxanthin (AXT) has antioxidative and anti-inflammatory effects in addition to its ability to shorten blood transit times. As laser speckle flowgraphy (LSFG) can noninvasively visualize the hemodynamics of the choroidal circulation, we used the technique to evaluate whether continuous ingestion of 12 mg of AXT per ...

Journal of applied physiology, 2014
To establish the accuracy of transcranial Doppler ultrasound (TCD) measures of middle cerebral artery (MCA) cerebral blood flow velocity (CBFV) as a surrogate of cerebral blood flow (CBF) during hypercapnia (HC) and hypocapnia (HO), we examined whether ...

VELOCITY OF BLOOD FLOW IN SCHIZOPHRENIA
Archives of Neurology And Psychiatry, 1938Our purpose in this study was to determine the rate of blood flow in patients with schizophrenia. The work of Blumgart 1 has stimulated interest in studies on the velocity of blood flow. The circulation time, while it does not directly determine the velocity of blood flow, is the denominator in the equation distance of pathway/circulation time equals ...

Effects of blood donation on cerebral blood flow velocity
Transfusion, 1990Eighteen healthy male blood donors, nine with hematocrit (Hct) of 0.40 to 0.45 (normal Hct) and nine with Hct of 0.49 to 0.52 (upper‐limit Hct), were monitored by continuous‐wave internal carotid Doppler sonography and hematologic tests for 28 days after blood donation, to ascertain whether and to what extent a single standard donation may modify the ...

The Effect of Remifentanil on Cerebral Blood Flow Velocity
Anesthesia & Analgesia, 1998In the present study, we investigated the effect of remifentanil on cerebral blood flow velocity (CBFV). We investigated 20 patients (ASA physical status III) scheduled for elective coronary artery bypass graft surgery. Anesthesia was induced with remifentanil 5 microg/kg IV (Group 1, n = 10) or 2 microg/kg IV (Group 2, n = 10) and was maintained with ...
