Pocket ultrasound devices for focused echocardiography [PDF]
Critical Care, 2012 Pocket ultrasound devices have recently been developed and may be particularly useful for emergency assessment. These devices can be stored in a pocket but share only some technical features with conventional echocardiographic machines. Two-dimensional imaging and color flow mode are available, with possible adjustments of global gain and depth, but ...

Metabolic Consequences of Rheumatoid Arthritis
Arthritis Care &Research, EarlyView.Patients with rheumatoid arthritis (RA) may have metabolic disruption, which can contribute to adverse long‐term outcomes, for multiple reasons. Patients with RA appear to have a higher risk of sarcopenia, type 1 and type 2 diabetes mellitus, metabolic syndrome, and hypertension. Systemic inflammation in RA can cause a “lipid paradox,” with reduced low‐

Analysis of Transcranial Focused Ultrasound Beam Profile Sensitivity for Neuromodulation of the Human Brain [PDF]
arXiv, 2015 Objective. While ultrasound is largely established for use in diagnostic imaging and heating therapies, its application for neuromodulation is relatively new and not well understood. The objective of the present study was to investigate issues related to interactions between focused acoustic beams and brain tissues to better understand possible ...

Anti-foci for focused ultrasound
International Journal of Hyperthermia, 2009 An anti-focus is defined as the point where the pressure amplitude is zero. As an active protection means in focused ultrasound, the anti-focus was researched through simulations. A 513 element, 1 MHz, 15 cm focal depth, spherical shape transducer with a central hold was used for the simulation.

The Regulation of Trace Metal Elements in Cancer Ferroptosis
Advanced Biology, EarlyView.The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Treatment of Movement Disorders With Focused Ultrasound [PDF]
Journal of Central Nervous System Disease, 2017 Although the use of ultrasound as a potential therapeutic modality in the brain has been under study for several decades, relatively few neuroscientists or neurologists are familiar with this technology. Stereotactic brain lesioning had been widely used as a treatment for medically refractory patients with essential tremor (ET), Parkinson disease (PD),

From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming
Advanced Engineering Materials, EarlyView.Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Focused cardiac ultrasound: FoCUS [PDF]
Serbian Journal of Anesthesia and Intensive Therapy, 2019 Focused cardiac ultrasound (FoCUS) is defined as pointof-care ultrasound examination, preformed according to a standardized, but restricted, scanning protocol in order to quickly determine the etiologies of cardiac dysfunction. The use of focused cardiac
