A High-definition Map Of Liver Cells In Health And Disease

Liver Cells
Researchers have created a high-resolution picture of the cells at work inside a key hub of metabolism — the liver — and shown how disease reprograms individual cell types. In every tissue throughout our bodies, various cell types communicate and coordinate their efforts to perform vital functions and maintain health. The new research not only …

Computer-assisted Method Helps Diagnose Glioma Tumor Growth

glioma diagnosis
A computer-assisted diagnostic procedure helps physicians detect the growth of low-grade brain tumors earlier and at smaller volumes than visual comparison alone, according to a new study by Hassan Fathallah-Shaykh of the University of Alabama at Birmingham, and colleagues. Additional clinical studies are needed to determine whether early therapeutic interventions enabled by early tumor growth …

Artificial Intelligence Tool Helps Detect Breast Cancer Early

artificial intelligence breast cancer detection
An artificial intelligence tool that could help detect breast lesions likely to become cancer has been developed by researchers at MIT. When breast cancer is detected early, it can often be treated successfully. The best available test currently is the mammogram, but they are still imperfect and often result in false positive results that can …

Retinal Imaging May Reveal Alzheimer’s Disease Signs

Vascular amyloidosis
A noninvasive eye imaging technique can identify beta amyloid protein deposits that mirror those in the brain, a study led by researchers at Cedars-Sinai and NeuroVision Imaging LLC reports. The work provides a scientific basis for using the experimental technology to detect the pathological hallmarks of Alzheimer's. Accumulations of neurotoxic beta-amyloid protein can be detected …

False-positive Mammograms Linked To Anxiety Prescriptions Spike

woman
Women who receive a false-positive mammogram result are newly prescribed anxiety or depression medication at a rate 10 to 20 percent higher than patients who receive an immediate negative result, new research shows. A false-positive result is one where a suspicious finding on the screening mammogram leads to additional testing that does not end up …

Liver Tumor Detection With Nanodiamond Manganese MRI Contrast Dye

nanodiamond team
A new nanodiamond-based contrast agent could improve visualization of liver cancer tumors. Contrast agents are chemical dyes that enhance the visibility of internal body structures in magnetic resonance imaging (MRI). MRI is commonly used for cancer diagnosis and to track the progress of patients after treatment. Currently, there are two modes of MRI imaging, T1-weighted …
