This case report describes a 30-year-old male admitted with intermittent fresh blood expectoration for three days and later found to have a small bleeding site on the posterior surface of the left tonsil. The authors diagnosed spontaneous tonsillar hemorrhage. They report successful management using low-temperature…

This single-institution cohort compared radiofrequency-assisted laparoscopic liver resection with open resection over 5 years (47 vs 87 patients). Laparoscopy was associated with lower blood loss and similar 5-year overall and disease-free survival compared with open surgery. The authors conclude the laparoscopic…

This engineering paper models the driving system of a centrifugal blood pump for extracorporeal circulation, focusing on disc magnetic coupling. It uses a three-dimensional static magnetic field edge element method in Ansys to numerically calculate magnetic fields and analyze how coupling parameters relate to…

This experimental animal study evaluated whether a radiofrequency method could induce thrombosis within an abdominal aortic aneurysm sac to potentially prevent endoleaks after endovascular repair. Six dogs received radiofrequency blood clotting of the sac and then stent-grafting, compared with a historical group of…

This paper describes the design and preliminary implementation of a mobile-phone-based wireless blood pressure monitoring system that transmits data via Bluetooth and computes blood pressure and heart rate on the phone. The authors state that experiments demonstrated the device’s reliability and stability, and that…

This engineering-focused mouse fMRI study evaluated a 400-MHz cryogenic RF probe (CryoProbe) versus a conventional room-temperature surface coil during electrical forepaw stimulation. The CryoProbe increased image SNR and temporal SNR and reduced temporal noise compared with the room-temperature coil. The authors…

This in vitro study examined terahertz electromagnetic radiation at NO-related spectral frequencies and its effects on blood rheology in patients with unstable angina treated with the NO donor isoket. The abstract reports that irradiated isoket had a better normalizing effect on blood viscosity and erythrocyte…

This retrospective case series reviewed four resections of symptomatic giant cavernous hepatic hemangiomas using an RF-powered multiarray (Habib sealer) for hepatic parenchymal transection. No blood transfusions were required and no major biliary or vascular injuries were observed at 1-year follow-up; one…

This paper models extravascular MRI signal decay (R2/R2*) as a function of blood oxygenation, vessel geometry, and magnetic field strength up to 9.4 T using Monte Carlo diffusion simulations. It reports different vessel-size dependencies for Hahn-spin-echo versus gradient-recalled-echo relaxation across field…
