International study defines reference values for satiety hormone leptin
Leptin is a key hormone in the regulation of hunger and satiety. For the first time, a large international study has established comprehensive reference values for leptin across all age groups and weight classes. More than 12,500 people from 16 European studies took part.

Recent research that measured fetal movements in pregnant women has found that higher frequencies were strongly linked to greater maternal attachment. Paying conscious attention to these signals may be a non-invasive and effective strategy for strengthening prenatal attachment and promoting more attentive and sensitive caregiving after birth.

Researchers from Karolinska Institutet, the Max Planck Institute for Empirical Aesthetics (Germany), Amsterdam UMC (Netherlands), in collaboration with other international partners, have conducted the most extensive study to date on adults who have never had sexual intercourse. The findings, published in the Proceedings of the National Academy of Sciences, suggest that lifelong sexlessness is associated with a multifaceted interplay of psychological, social, and genetic factors.

Children diagnosed with autism are far more likely to experience ongoing gastrointestinal (GI) problems than their typically developing peers. That's the finding of a new UC Davis MIND Institute study published in Autism. The research also found that these stomach and digestive issues are linked to greater challenges with sleep, communication, sensory processing and behavior.

Have you ever mentally mapped out the streets between your home and your workplace or favorite café, focusing solely on those two places without visualizing what exists in between them? If you have, you will know that, in our minds, it often seems there is no distance between the places that interest us… or at least not as much as there really is.

157. High-fat diet can impair memory formation by disrupting cellular recycling

  • 1 day ago schedule
  • medicalxpress.com language

Modern lifestyles and dietary changes have significantly increased the consumption of high-fat foods, contributing to a steep rise in the prevalence of obesity, diabetes, and metabolic disorders. Furthermore, a high-fat diet (HFD) is linked to cognitive impairments and neurodegeneration and has been shown to worsen the pathology of Alzheimer's disease—a progressive neurodegenerative condition—in mouse models. Yet, the underlying mechanisms remain largely elusive.

Researchers show that stretching the skin stimulates immune cells and increases the skin's ability to absorb large molecules, including those present in vaccines. In an article published September 17 in Cell Reports, they claim that applying vaccines topically while stretching the skin resulted in more effective immunization than subcutaneously injecting the vaccine in mice.

A USC Stem Cell-led research team has achieved a major step forward in the effort to build mouse and human synthetic kidneys. In a new paper published in Cell Stem Cell, the scientists describe generating more mature and complex lab-grown kidney structures (organoids) than ever before.

160. Study of young athletes finds neurodegeneration might begin before chronic traumatic encephalopathy

  • 1 day ago schedule

This fall, tens of millions of people will be at risk for chronic traumatic encephalopathy (CTE), a degenerative brain disease caused by repeated head impacts from contact sports like football, soccer, and ice hockey, or military service. Researchers have long suspected that the brain begins changing years before CTE appears, but proof has been elusive because CTE can only be definitively diagnosed after death.

Could cocoa extract supplements rich in cocoa flavanols reduce inflammation and, in turn, prevent age-related chronic diseases?

162. Novel way to 'rev up' brown fat burns calories, limits obesity in mice

  • 1 day ago schedule
  • medicalxpress.com language

Researchers at Washington University School of Medicine in St. Louis have identified a novel way brown fat—an energy-burning form of fat—can rev the body's metabolic engine, consuming cellular fuel and producing heat in a way that improves metabolic health. The study, in mice, reveals new avenues to exploit brown fat to treat metabolic diseases, such as insulin resistance and obesity.

Fat is more complicated than we thought. Once considered just a bag of calories, scientists now know that our fat—aka adipose tissue—doesn't just squirrel away energy; it also sends and receives hormonal, nervous system and immune signals.
