This and That

Adolescents who sleep poorly and insufficiently may develop alcohol and drug problems
Here, let me fix that...
Adolescents with infections may sleep poorly and self-medicate with alcohol and drugs.
Especially if they are told to eat corn oil instead of saturated fats.

Eczema woes not just skin deep
Adults who have eczema -- a chronic itchy skin disease that often starts in childhood -- have higher rates of smoking, drinking alcoholic beverages and obesity and are less likely to exercise than adults who don't have the disease. They also have a higher risk of cardiovascular disease and diabetes. About 10 percent of US adults have eczema.
See how that works?

Environment, not genes, dictates human immune variation
Much has been made of the role genes play in human health. Stunning advances in gene-sequencing technologies, in concert with their plummeting costs, have turned many scientists' attention to minute variations in the genome -- the entire toolbox of genes carried in virtually every cell in the body -- in the hope of predicting people's future health. Such studies have revealed a genetic contribution to health outcomes. But, with some notable exceptions, very few individual genetic variants contribute much to particular health conditions.

Could our brain instruct our bodies to burn more fat?
Monash University researchers unravelled a molecular mechanism that depends on the combined action of two hormones - leptin, an appetite suppressant generated in fat cells, and insulin, produced in the pancreas in response to rising levels of glucose in the blood. Their research shows that the two hormones act in concert on a group of neurons in the brain to stimulate the burning of body fat via the nervous system.
Lead researcher Professor Tony Tiganis, from the Department of Biochemistry and Molecular Biology said discovering the combined action of these two hormones makes could assist in the shedding of excess fat.
"These hormones give the brain a comprehensive picture of the fatness of the body. Because leptin is produced by fat cells, it measures the level of existing fat reserves - the more fat, the more leptin. Whereas insulin provides a measure of future fat reserves because glucose levels rise when we eat," Professor Tiganis said.
I really need to study some more about leptin.   My entire metabolism changes when I weigh more than 145.   Maybe this week...
