| Landmark study points to source of rapid aging, chronic inflammation in people living with HIV Posted: 09 Nov 2021 12:51 PM PST In a groundbreaking study of people living with HIV, researchers found that elusive white blood cells called neutrophils play a role in impaired T cell functions and counts, as well as the associated chronic inflammation that is common with the virus. |
| Retinoid therapy may improve vision in people with rare genetic disorder Posted: 09 Nov 2021 09:06 AM PST Using data generated from patients and mice with genetic mutation for the disorder Usher syndrome, researchers documented the natural history of vision impairment in patients and identified the cell mechanism behind progressive vision loss. Based on these findings, the team was able to test a retinoid therapy that improved vision in mice with Usher syndrome. The researchers said assessing a similar therapy should now be considered in people with Usher syndrome to see if this therapy might slow vision loss. |
| A potential role for ibuprofen in older adults’ immunity to RSV Posted: 09 Nov 2021 09:03 AM PST New research suggests there may someday be a role for ibuprofen in providing older adults with lasting immunity against RSV, a virus commonly associated with infants and young kids that also rivals the flu as a dangerous wintertime infection for the elderly. |
| Drug used to prevent miscarriage increases risk of cancer in offspring Posted: 09 Nov 2021 09:03 AM PST Exposure in utero to a drug used to prevent miscarriage can lead to an increased risk of developing cancer, according to researchers. |
| How to turn specific genes on and off Posted: 09 Nov 2021 09:03 AM PST Type 1 diabetes, rheumatoid arthritis, and cancer are just some of the disorders associated with specific genes not 'turning on' and 'turning off' as they should. By using new CRISPR/Cas9 genome editing technology researchers have described a new technique that scientists across the world can potentially use to explore novel ways of treating diseases associated with dysregulation in DNA methylation. |
| Safety concerns raised for neuroblastoma candidate drug Posted: 09 Nov 2021 09:03 AM PST Scientists have identified the primary target of the experimental cancer drug CX-5164, revealing a possible risk for late effects of treatment. |
| Fat-secreted molecule lowers response to common cancer treatment Posted: 09 Nov 2021 06:53 AM PST Leptin, a molecule produced by fat cells, appears to cancel out the effects of the estrogen-blocking therapy tamoxifen, a drug commonly used to treat and prevent breast cancers, suggests a new study. |
| Anxiety effectively treated with exercise Posted: 09 Nov 2021 06:53 AM PST Both moderate and strenuous exercise alleviate symptoms of anxiety, even when the disorder is chronic, a new study shows. |
| Microbiome discovery could help save kids’ hearing Posted: 09 Nov 2021 06:53 AM PST Bacteria found in children's upper respiratory systems could help fight chronic middle ear infections, the leading cause of preventable hearing loss and deafness in Indigenous communities. |
| Cellular aging: A basic paradox elucidated Posted: 09 Nov 2021 06:53 AM PST Cancer researchers show for the first time that cellular senescence, which occurs when aging cells stop dividing, is caused by irreversible damage to the genome rather than simply by telomere erosion. |
| An innovative imaging technique for dynamic optical nanothermometry Posted: 09 Nov 2021 05:50 AM PST A new imaging technique can measure temperature in 2D, without contact, and in just a snap. |
| Lack of important molecule in red blood cells causes vascular damage in type 2 diabetes Posted: 09 Nov 2021 05:08 AM PST Altered function of the red blood cells leads to vascular damage in type 2 diabetes. Results from a new study in cells from patients with type 2 diabetes and mice show that this effect is caused by low levels of an important molecule in the red blood cells. |
