The study found that in patients with severe obesity, the force response to high calcium was reduced by 40%, suggesting that obesity is the key factor.
A study of 52,000 participants found that those with detectable brown fat were less likely to suffer cardiac and metabolic conditions. Brown fat burns energy, and its presence was linked to lower risk of hypertension, congestive heart failure, and coronary artery disease.
Scientists at UT Southwestern Medical Center have discovered a type of cell responsible for triggering chronic inflammation in fat tissue. The study found that these cells, called fibro-inflammatory progenitors (FIPs), produce signals that encourage inflammation when exposed to high-fat diets.
Researchers found that a protein called Cx43 allows stress signals from one liver cell to spread to neighboring cells, causing dysfunction. Mice with deleted Cx43 were protected from insulin resistance, glucose intolerance, and non-alcoholic fatty liver disease.
A new study suggests that COVID-19 patients with obesity have poor outcomes, but this is not due to increased inflammation. Instead, respiratory issues and other factors may play a role. The researchers found that patients with obesity had lower inflammatory markers on hospital days, which could contribute to their poor clinical outcomes.
Researchers found that water suppresses vasopressin, a hormone linked to obesity and diabetes, alleviating conditions in mice. Water therapy effectively protected against metabolic syndrome, a collection of conditions increasing the risk of heart disease and type 2 diabetes.
Research reveals that telomere shortening, linked to excessive stem cell division, predisposes fat cells to premature senescence and tissue dysfunction. Shorter telomeres in patients with metabolic dysfunction also showed resistance to weight loss treatments.
Researchers from KAIST and Florida State University developed a model describing PER molecule motion in cells, showing how aging and diseases disrupt circadian rhythms by hindering condensation around the cell nucleus. This leads to irregular sleep-wake cycles and unstable rhythms.
A study published in The BMJ found that dog owners with diabetes are more likely to develop type 2 diabetes themselves than owners without a diabetic dog. However, no shared risk was found between cat owners and their pets.
