Study reveals two distinct types of obesity with physiological and molecular differences

A team led by Van Andel Institute scientists has identified two distinct types of obesity with physiological and molecular differences that may have lifelong consequences for health, disease and response to medication. The findings, published today in the journal Nature Metabolism, offer a more nuanced understanding of obesity than current definitions and may one day inform more precise ways to […]

How changes in length of day change the brain and subsequent behavior

Seasonal changes in light—longer days in summer, shorter in winter—have long been associated with human behaviors, affecting everything from sleep and eating patterns to brain and hormonal activity. Seasonal affective disorder (SAD) is a prime example: A type of depression related to diminished exposure to natural sunlight, typically occurring during winter months and more often at higher latitudes when daylight […]

Study compares the benefits of taking antihypertensive medication in the morning or evening

A pragmatic randomised trial in more than 21,000 patients with high blood pressure followed for over five years has concluded that protection against heart attack, stroke and vascular death is not affected by whether antihypertensive medications are taken in the morning or evening. The late breaking research is presented in a Hot Line session today at ESC Congress 2022 and […]

Neoadjuvant immunotherapy improves outlook in high-risk melanoma

Patients with high-risk melanoma who received the immunotherapy drug pembrolizumab both before and after surgery to remove cancerous tissue had a significantly lower risk of their cancer recurring than similar patients who received the drug only after surgery. These results from a research study by the SWOG Cancer Research Network, a cancer clinical trials group funded by the National Cancer […]

Interactions between SIRT5 and SARS-CoV-2 Nsp14 protein

In a recent study published in the PLOS Pathogens journal, researchers investigated the interactions between sirtuin 5 (SIRT5) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nonstructural protein (Nsp14) protein. Study: SIRT5 is a proviral factor that interacts with SARS-CoV-2 Nsp14 protein. Image Credit: CROCOTHERY/Shutterstock The highly conserved enzyme called SARS-CoV-2 Nsp14 is essential for viral replication. The non-structural protein […]

Access to New Cancer Treatment Is a Hurdle for Rural Americans

Suzanne Behanna initially turned down an experimental but potentially lifesaving cancer treatment. Three years ago, the newlywed, then 62, was sick with stage 4 lymphoma, sick from two failed rounds of chemotherapy, and sick of living in a trailer park near the University of Texas MD Anderson Cancer Center in Houston. It was fall 2019, and treatment had forced her […]
