Alzheimer’s Diagnosis, Management Improved by Brain Scans

A first-of-its-kind national study has found that a form of brain imaging that detects Alzheimer’s-related “plaques” significantly influenced clinical management of patients with mild cognitive impairment and dementia. The study revealed that providing clinicians with the results of positron emission tomography (PET) scans that identify amyloid plaques in the brain […]

The Doctor and the Machine

A 49-year-old man notices a painless rash on his shoulder but doesn’t seek care. Months later, during a routine physical, his doctor notices the rash and diagnoses it as a benign skin condition. More time passes, and during a routine screening test, a nurse points out the rash to another […]

Computational model of a human kinase may provide insights for cancer treatment

Researchers have developed a computational model for human MEK1, a protein with potential as a drug target for a variety of human cancers. The initiation and progression of cancer cells occur when molecular signals involved in cellular proliferation go awry. MEK1 plays an essential role in signaling within both healthy […]

Urine Test to Evaluate Immunotherapy Success Gets $1.8 Million NIH Research Grant

New immunotherapies can dramatically defeat cancer. But more often, cancer evades them, and doctors need to know quickly when that happens, so they can adjust treatment. An experimental urine test to detect immunotherapy effectiveness very early has received a major funding boost. The National Institutes of Health has granted $1.8 […]

How Immune Cells Help Tumors Escape Body's Defenses

New research from the University of Pittsburgh School of Medicine and the UPMC Hillman Cancer Center sheds light on how tumors use the body’s regulators of immunity for their own benefit. Published in Nature Immunology, the findings could be used to develop the next generation of immune therapies to fight various cancers. “While cancer immunotherapy […]

Metastatic prostate cancer may have its own biomarker, UB research finds

Prostate cancer can grow slowly and pose little threat to patients, or it can metastasize quickly, causing severe pain and death. But as of now, it’s nearly impossible to determine which type of cancer a patient has during the early stages. Now, University at Buffalo researchers and scientists from Moscow […]

Laser Technology Helps Researchers Scrutinize Cancer Cells

Devising the best treatment for a patient with cancer requires doctors to know something about the traits of the cancer from which the patient is suffering. But one of the greatest difficulties in treating cancer is that cancer cells are not all the same. Even within the same tumor, cancer […]

Biopsy Alternative: ‘Wearable’ Device Captures Cancer Cells From Blood

A prototype wearable device, tested in animal models, can continuously collect live cancer cells directly from a patient’s blood. Developed by a team of engineers and doctors at the University of Michigan, it could help doctors diagnose and treat cancer more effectively. “Nobody wants to have a biopsy. If we […]

A bad bout of flu triggers ‘taste bud cells’ to grow in the lungs

Most people who weather an infection with influenza fully recover after a week or two. But for some, a severe case of the flu can actually reshape the architecture of their lungs and forever compromise their respiratory function. With a surprising new finding, researchers from Penn have identified what they […]

‘Jumping genes’ drive many cancers

Mistakes in DNA are known to drive cancer growth. But a new study, from Washington University School of Medicine in St. Louis, heavily implicates a genetic phenomenon commonly known as “jumping genes” in the growth of tumors. The study is published in the journal Nature Genetics. Since jumping genes aren’t […]

Introducing a kinder, gentler way to blow holes in cells

When scientists attempt to slip big molecules, like the Cas9 enzyme that is key to CRISPR gene editing, into cells, things can get messy. One popular technique, bulk electroporation, involves jolting cells with electricity. This blows holes everywhere in the cell, allowing anything and everything to get inside. Delicate cells, […]
