Why Does Parkinson’s Disease Effect Women And Men Differently?

There is growing evidence that Parkinson’s disease (PD) affects women and men differently. In a new review[1] scientists present the most recent knowledge about these sex-related differences and highlight the significance of estrogens, which play an important role in the sex differences in PD. “It is becoming increasingly evident that…Continue readingWhy Does Parkinson’s Disease Effect Women And Men Differently?

Does Osteocalcin, Not Adrenaline, Drive Fight Or Flight Response?

The “fight or flight” response, is commonly believed to be triggered in part by the hormone adrenaline. But a new study[1] from researchers at Columbia University suggests that bony vertebrates are not able to produce this response to danger without the skeleton. The researchers found in mice and humans that…Continue readingDoes Osteocalcin, Not Adrenaline, Drive Fight Or Flight Response?

Ghrelin Makes Food Smells Harder To Ignore

The hormone ghrelin makes us more susceptible to appealing food smells, a phenomenon that encourages overeating and obesity, according to new research. Earlier work by Alain Dagher’s lab at the Montreal Neurological Institute and Hospital of McGill University and colleagues demonstrated that ghrelin encourages eating and the production of dopamine,…Continue readingGhrelin Makes Food Smells Harder To Ignore

Lab-grown Human Retinas Show How Color Vision Develops

Biologists have grown human retina tissue from scratch to learn how the cells that let us see in color are made. The work may lay the groundwork for therapies for eye diseases such as color blindness and macular degeneration. It also establishes lab-created organoids — artificially grown organ tissue — as…Continue readingLab-grown Human Retinas Show How Color Vision Develops

Fathers’ Postnatal Hormone Levels Predict Later Caregiving

Fathers whose cortisol levels were elevated while they held their newborns on the day of their birth — either skin-to-skin or clothed — were more likely to be involved with indirect care and play with their infants in the first months of their lives, a new study indicates. In a…Continue readingFathers’ Postnatal Hormone Levels Predict Later Caregiving

FGF23: Hormone Linked To Structural Brain Deficits

The ways that high levels of a hormone called fibroblast growth factor 23 (FGF23) can reduce brain health have been uncovered by researchers at the Medical University of South Carolina (MUSC). High levels of FGF23 were associated with structural changes in the brain’s frontal lobes. High FGF23 levels are thought…Continue readingFGF23: Hormone Linked To Structural Brain Deficits

Thyroid Hormone Shows Promise For Fighting NAFLD

A thyroid hormone shows promise in fighting non-alcoholic fatty liver disease (NAFLD) in patients with diabetes, according to new research. The disease, a major global health problem characterized by accumulation of fat in the liver, develops in patients with obesity, type 2 diabetes, dyslipidaemia, and insulin resistance. The presence of…Continue readingThyroid Hormone Shows Promise For Fighting NAFLD
