Gas types affect stability of microbubbles and ultrasound mediated brain-targeted drug delivery
Ultrasound (US) is used for clinical diagnosis and therapy. Microbubbles (MBs) as US-contrast agents are applied to detect micro blood flow or specific lesions. Recently, the combination of MBs and US has received much attention for drug
Exercise inhibits cancer: the mechanosensitive state of tumor cells
Surprisingly, researchers find that tumor cells are sensitive to mechanical stresses. This may provide new ways to treat cancers without the severe side-effects of many therapies. Because mechanosensitivity of cancer cells is found quite generally, it appears
Ultrasound generate electricity inside the body
Implantable medical devices (IMDs) are highly beneficial to patient health. Concerning rapidly evolving technologies for IMDs, sustainable and reliable powering methods for IMDs is truly essential. They are generally relying on primary batteries, which are subject to
Compressed ultrasound imaging: finding tumors with a few transducers
Currently, ultrasound imaging is predominantly done by a probe that possesses many transducers, which are small devices that transmit, and then receive, acoustic waves. Decreasing the number of transducers, while maintaining image quality, is surely a desirable
Unknown sonochemistry
The chemical effects of ultrasound, named sonochemistry, are known since 1927. Today, there is a consensus within the scientific community that sonochemistry arises from the violent collapse of microbubbles formed in liquids submitted to power ultrasonic waves.
Looking for liver disease in babies with intestinal failure on TPN: can ultrasound replace liver biopsy?
In order to get proper nutrition to grow, a person needs to be able to use their small bowel to absorb nutrients. Some babies and children have diseases that require removal of a significant length of their
Transmitted sound wave mammography
This study was designed to look at a new type of totally harmless breast imaging called whole-breast transmission ultrasound to see if it could do something mammography cannot do – that is to diagnose the presence of
Ultrasound can help small particles penetrate into biofilms using a new oscillatory diffusion mechanism
Biofilms form when microorganisms, such as bacteria or algae, attach to a surface and surround themselves with a matrix of extracellular polymeric substance (or EPS). Biofilms are ubiquitous in nature and in a vast array of industrial
Ultrasound effect on cancerous versus non-cancerous cells
Cancer research is one of the most researched topics over the past decade. The reason for that is obvious, in 2016 alone, 1,685,210 new cancer cases and 595,690 cancer deaths are projected to occur in the United
The use of multisite ultrasound in cardiac arrest – the SESAME-protocol
Cardiac arrest is the most critical emergency. The sudden interruption of oxygen supply damages the brain after some minutes. Finding a cause for efficiently fixing the problem is the main target of the frontline physician. Ultrasound is
Utrasound-guided core-needle biopsy in thyroid nodules: 676 cases with surgical correlation
Thyroid nodules are a frequent problem. Most are benign, but up to 15% of them are malignant tumours. Ultrasound is the indicated technique to explore thyroid and search for nodules. When a nodule is discovered and it
Ultrasounds for heart infections can be reduced by following simple rules
Staphylococcus aureus bacteria often cause severe bloodstream infections, called Staph aureus bacteremia (SAB). Once Staph aureus enters the bloodstream it can spread to the heart and cause an infection of the heart valves called infective endocarditis (IE).
Ultrasound in medical education
Ultrasound is a type of energy that can be used in medicine for both making diagnoses and treating patients. Like the sound of a voice, a person uses air passing across the vocal cords to produce noises
