Boosting a single brain molecule can change 'dispositional anxiety' in nonhuman primates

Boosting a single molecule in the brain can change "dispositional anxiety," the tendency to perceive many situations as threatening, in nonhuman primates, researchers from the University of California, Davis, and the University of Wisconsin-Madison have found.

Tighter blood pressure control could improve brain health finds study

Tighter blood pressure control is standard practice in hypertension therapy. Researchers have found that in addition to the benefits this provides to the heart and the vascular system, it also helps lower the risk of cognitive decline and dementia associated with age

Researchers develop new strategy to target metastases in lymph nodes

Metastasis, in which cancer cells break free from the primary tumor and form tumors at other sites, worsens the prognosis for many cancer patients.

Abnormal blood pressure in middle age and late life increases dementia risk

In a study that spanned two and a half decades and looked at data from more than 4,700 participants, Johns Hopkins researchers have added to evidence that abnormal blood pressure in midlife persisting into late life increases the likelihood of developing dementia.

Global air pollution linked to increased emphysema cases

A new study funded by the NIH says that increasing rates of the chronic lung condition called emphysema are linked to breathing polluted air over a long period. The progression of emphysema, a condition more commonly linked to smoking, is now also being attributed to polluted air. Air pollution is already known to be associated with lung and cardiovascular disease.

Trump administration hits brakes on law to curb unneeded Medicare CT scans, MRIs

Five years after Congress passed a law to reduce unnecessary MRIs, CT scans and other expensive diagnostic imaging tests that could harm patients and waste money, federal officials have yet to implement it.

Greater blood pressure control associated with fewer adverse changes in the brain

For adults with high blood pressure, greater blood pressure control than what's currently considered standard is associated with fewer adverse changes of the brain, which could mean lower risks of dementia and cognitive impairment, according to new research published in the Journal of the American Medical Association.

Psychiatric symptoms may indicate the beginning of Alzheimer’s disease

Researchers at UC San Francisco (UCSF) and the University of São Paulo have shown that the earliest stages of Alzheimer’s brain pathology are tightly linked to neuropsychiatric symptoms such as anxiety, depression and sleep disturbances.

Assessing blood flow is key to early detection, treatment for patients with critical limb ischemia

Non-invasive techniques and devices for assessing blood flow and other diagnostic considerations for people with critical limb ischemia are addressed in a new scientific statement from the American Heart Association, published in the Association's flagship journal Circulation.

Diagnostic value of ultrasound in comparing different types of arthritis

Ultrasound is a non-invasive and relatively inexpensive means of diagnosing a number of medical conditions. This review presents an analysis of the diagnostic value of ultrasound to draw comparison between different types of arthritic conditions.

Nanoparticles' movements reveal whether they can hit intended cancer targets

Targeted drug-delivery systems hold significant promise for treating cancer effectively by sparing healthy surrounding tissues. But the promising approach can only work if the drug hits its target.

Depression symptoms together with AD pathology could trigger changes in memory and thinking

Increasingly, Alzheimer's disease research has focused on the preclinical stage, when people have biological evidence of AD but no or minimal symptoms, and when interventions might have the potential to prevent future decline of older adults.

BrainHealth research explores the neurochemistry of social perception

Cues signaling trust and dominance are crucial for social life. Recent research from Dr. Dan Krawczyk's lab at the Center for BrainHealth explored whether administering two chemically similar hormones known to affect social cognition - oxytocin and vasopressin - would influence the perception of trustworthiness and/or social dominance.

Strong free-electron lasers can be used to break down amyloid protein aggregates

Amyloid fibrils are a type of self-assembled proteins/peptides that take on a stacked sheet-like formation. Amyloid fibril aggregates are known to be a cause of several diseases--including Alzheimer's--and therefore, it is of immense scientific interest to understand how these aggregates can be broken.
