Hot flashes impair memory performance

Published: Thu, 23 Jan 2020 09:58:59 EST

If you're having difficulty identifying the right word to express yourself clearly or remembering a story correctly, you may blame menopause. A new study suggests that physiologic hot flashes are associated with decreased verbal memory and with alterations in brain function during encoding and retrieval of memory, especially in the hippocampus and prefrontal cortex.

Low doses of radiation used in medical imaging lead to mutations in cell cultures

Published: Thu, 16 Jan 2020 14:17:31 EST

Common medical imaging procedures use low doses of radiation that are believed to be safe. A new study, however, finds that in human cell cultures, these doses create breaks that allow extra bits of DNA to integrate into the chromosome.

Peering into the genome of brain tumor

Published: Thu, 09 Jan 2020 10:08:23 EST

Scientists have created a machine learning method for classifying the mutations of glioma brain tumors based on MR images alone. Thus far, classification has only been possible by tissue sampling during surgery. The new method is noninvasive, may remove the need for a tissue sample and help accelerate delivery of treatment for patients.

Children frequently receive unnecessary medical care regardless of insurance type

Published: Tue, 07 Jan 2020 16:50:48 EST

Children with public insurance are slightly more likely to receive medical services that they don't need than those with private insurance, a new study finds.

Scientists capture for first time, light flashes from human eye during radiotherapy

Published: Tue, 07 Jan 2020 14:23:09 EST

People have long reported seeing flashes of light during brain radiotherapy. Until now, no one has been able to capture evidence of this sensation in humans, and only theory, models, and speculation exist to explain it. Scientists, for the first time, have not only caught real-time observation of this phenomenon, but explain how the light is produced in the eye when radiation passes through it.

False negatives: Delayed Zika effects in babies who appeared normal at birth

Published: Mon, 06 Jan 2020 22:24:59 EST

Colombian infants exposed to Zika virus in the womb showed neurodevelopmental delays as toddlers, despite having 'normal' brain imaging and head circumference at birth, a finding that underscores the importance of long-term neurodevelopmental follow-up for Zika-exposed infants.

New radiotracer offers opportunities for earlier intervention after heart attack

Published: Thu, 02 Jan 2020 18:48:27 EST

A new radiotracer can effectively image fibroblast activation after a heart attack, identifying a window of time during which cardiac fibrosis can be prevented and the disease course altered.

Alzheimer 'tau' protein far surpasses amyloid in predicting toll on brain tissue

Published: Wed, 01 Jan 2020 14:40:12 EST

The results support researchers' growing recognition that tau drives brain degeneration in Alzheimer's disease more directly than amyloid protein, and at the same time demonstrates the potential of recently developed tau-based PET (positron emission tomography) brain imaging technology to accelerate Alzheimer's clinical trials and improve individualized patient care.

Super-resolution at all scales with active thermal detection

Published: Mon, 23 Dec 2019 12:29:05 EST

A research team found the temperature increase caused by the probe beam could be utilized to generate a signal per se for detecting objects. Notably, this so-called 'active thermal detection' enables super-resolution imaging at all scales.

Researchers produce first laser ultrasound images of humans

Published: Fri, 20 Dec 2019 15:05:53 EST

Engineers have come up with an alternative to conventional ultrasound that doesn't require contact with the body to see inside a patient. The new laser ultrasound technique leverages an eye- and skin-safe laser system to remotely image the inside of a person.

Possible link between cannabis use and structural changes to heart

Published: Wed, 18 Dec 2019 15:35:11 EST

Regular cannabis use could affect the structure and function of the heart.

Finding a non-invasive way to predict effectiveness of cancer therapy

Published: Fri, 13 Dec 2019 09:25:09 EST

Researchers have taken a critical step toward developing a non-invasive nuclear medicine technique that can predict the effectiveness of therapy for cancerous tumors, allowing for personalized, precision treatment.

Experts review evidence yoga is good for the brain

Published: Thu, 12 Dec 2019 10:58:51 EST

Scientists have known for decades that aerobic exercise strengthens the brain and contributes to the growth of new neurons, but few studies have examined how yoga affects the brain. A review of the science finds evidence that yoga enhances many of the same brain structures and functions that benefit from aerobic exercise.

Veterans study suggest two sub-types of Gulf War illness

Published: Thu, 12 Dec 2019 08:19:30 EST

Brain imaging of veterans with Gulf War illness show varying abnormalities after moderate exercise that can be categorized into two distinct groups -- an outcome that suggests a more complex illness that previously thought.

New technique to determine protein structures may solve biomedical puzzles

Published: Wed, 11 Dec 2019 14:56:13 EST

Researchers have now demonstrated a powerful 'experimental evolution' method to discover details of protein shape and function, and the method may find uses across a very broad spectrum of biomedical research.

Artificial intelligence boosts MRI detection of ADHD

Published: Wed, 11 Dec 2019 14:56:09 EST

Deep learning, a type of artificial intelligence, can boost the power of MRI in predicting attention deficit hyperactivity disorder (ADHD), according to a new study. Researchers said the approach could also have applications for other neurological conditions.

A window into the hidden world of colons

Published: Wed, 11 Dec 2019 08:27:05 EST

Biomedical engineers have developed a system for real-time observations at the cellular level in the colon of a living mouse. It employs a magnetic system to stabilize the colon during imaging while otherwise allowing the gut to move and function normally. Researchers expect the procedure to allow new investigations into the digestive system's microbiome as well as the causes of diseases and their treatments.

Imaging of conjunctival goblet cells helps diagnosis of dry eyes

Published: Thu, 05 Dec 2019 11:31:53 EST

Researchers have developed a biometric imaging of conjunctival goblet cells with high definition.

Cellular repair response to treadmill test can predict cardiac outcomes

The information gained from the changes in CPC counts during exercise may be more useful to cardiologists in risk stratifying these patients than the treadmill exercise test itself, the researchers say.

Successful instrument guidance through deep and convoluted blood vessel networks

Published: Tue, 03 Dec 2019 14:33:11 EST

Researchers have developed a novel approach to tackling one of the biggest challenges of endovascular surgery: how to reach the most difficult-to-access physiological locations. Their solution is a robotic platform that uses the fringe field generated by the superconducting magnet of a clinical MRI scanner to guide medical instruments through deeper and more complex vascular structures. The approach has been successfully demonstrated in-vivo.
