Ultrasound News and Research

RSS

Ultrasound is a procedure in which high-energy sound waves are bounced off internal tissues or organs and make echoes. The echo patterns are shown on the screen of an ultrasound machine, forming a picture of body tissues called a sonogram. Also called ultrasonography.

Rice Researchers Map Protein Interactions for Creating Functional Gas Vesicles

As far as water gear goes, floaties are not exactly high tech. But the tiny air-filled bubbles some microorganisms use as flotation devices when they compete for light on the water surface are a different story.

Noninvasive Ultrasound Method Enables Tracking of Gene Expression in Specific Brain Regions

The ability to alter or prevent the expression of faulty genes in the brain could be leveraged as a powerful therapeutic against neurodegenerative disease. However, the molecular underpinnings of the living brain are still largely inaccessible, hampering progress on such promising therapeutics.

Ultrasound-Triggered Nanodroplets for Targeted Drug Delivery

Conventional drug delivery is often like cracking a nut with a sledgehammer. Whether the drug is swallowed, injected, inhaled, or absorbed through the skin, it ultimately diffuses to most parts of the body, including those where it isn’t needed – or where it even might cause harm.

Barbastelle Bats' Quiet Hunting a Matter of Chance, Not Adaptation

When inquiring with a biologist about why predators do not completely eliminate their prey, they frequently point to an enduring evolutionary competition between predators and prey, wherein both sides continually develop novel strategies to outsmart one another.

Improving the Efficiency of Gene Delivery to the Brain

Researchers from Rice University conducted tests to assess the safety and feasibility of gene delivery to various regions of the brain using a noninvasive technique based on ultrasound in rodents.

Integrating Ultrasound with Genetics to Precisely Modify Neurons in the Brain

Researchers have developed methods to study and manipulate areas of the brain, though many of those methods are restricted by the limited depth that light can reach within the brain. A multidisciplinary team at Washington University in St. Louis plans to overcome that limitation by integrating ultrasound with genetics to precisely modify neurons in the brain.

Research may Offer a New Way to Break Through Cancer's Hypoxia-Induced Defenses

For most of our tissues and cells, a lack of oxygen, or hypoxia, is bad news. Cancer cells, on the other hand, can thrive in these hypoxic conditions, which render tumors less susceptible to anti-cancer treatments, including radiation.

Attaching Microbubbles to Macrophages can Create Tracking Images for Tumor Diagnosis

Macrophages, a type of white blood cell, defend the body by engulfing and digesting foreign particles, such as bacteria, viruses, and dead cells.

Retinal Microvasculature may be a Potential Biological Indicator for Predicting Acute Mountain Sickness

This study is led by Dr.Ningli Wang and Dr.Yuan Xie (Beijing Tongren Hospital, Capital Medical University), they provide evidence that retinal microvasculature is a potential biomarker for cerebral microvasculature changes and acute mountain sickness(AMS) development during risk assessment of individuals at high altitudes.

Using nanoparticles to carry drugs across the blood-brain barrier

Brain tumors are notoriously hard to treat. One reason is the challenge posed by the blood-brain barrier, a network of blood vessels and tissue with closely spaced cells.

Using ultrasound waves to move genetically engineered cells

Let's say you needed to move an individual cell from one place to another. How would you do it? Maybe some special tweezers? A really tiny shovel?

Deep-learning approach to achieve faster and high-resolution photoacoustic computed tomography

It takes a few moments for the sound of thunder to reach our ears after a flash of lightning. This phenomenon is due to the photoacoustic (PA) effect where materials near the lightning instantly expand as the optical energy of the lightning is absorbed and converted into thermal energy.
