Reproductive rates in humans are linked to metabolic energy expenditure and body mass, with women in wealthy nations experiencing low birth rates due to high caloric intake. This relationship highlights the importance of considering biological scaling laws when understanding human reproductive patterns.
A recent study published by the American Heart Association found that eating fast food meals more than twice a week was associated with double the risk of abnormal glucose control and a 50% increase in obesity risk. Additionally, frequent TV viewing habits were linked to increased odds of obesity and abnormal glucose metabolism.
Researchers at Baylor College of Medicine found that a specific enzyme is associated with high levels of HDL, which may have both positive and negative effects on cardiovascular health. The study suggests that the enzyme's impact on cholesterol transport to the liver could be beneficial or detrimental.
Researchers at the University of Pittsburgh discovered that PTHrP significantly increases bone mineral density in postmenopausal women with osteoporosis, with a 4.7% increase observed in just three months. The study's findings are promising and take the identification of an effective short-term anabolic agent one step further.
A genetic variant in the CYP2B6 gene has been found to impact smoking cessation success. Researchers discovered that smokers with a decreased activity variant of this gene were more likely to relapse during treatment. The study also suggests that bupropion may be more effective for female smokers, particularly those with the polymorphism.
Directed antisense expression has been shown to moderate feeding behavior and weight gain in various animal models. This regulatory effect is attributed to the suppression of genes involved in energy homeostasis, ultimately leading to changes in food intake and body weight.
Scientists have identified several genes that affect how much alcohol reaches the brain and how long it remains there, shedding light on individual differences in alcohol metabolism. The findings could lead to new treatments for alcoholism and highlight the importance of further research into the genetic factors involved.
Researchers discovered that guggulsterone blocks the FXR receptor, regulating cholesterol metabolism. The study suggests that guggulsterone could lead to new drugs to control cholesterol levels and potentially treat hyperlipidemia.
A study published in Science identifies guggulipid as a target for developing drugs to lower cholesterol. The extract, combined with a cholesterol-lowering diet, reduced cholesterol levels by up to 20%. Researchers are now studying the biochemical reasons behind this effect and its potential impact on other medications.
A study found that Chinese-Americans take in less nicotine per cigarette and metabolize it more slowly than whites and Latinos, possibly explaining lower lung cancer rates. This correlation suggests slow nicotine metabolism may contribute to reduced nicotine intake, a factor linked to lower lung cancer incidence.
Researchers at Columbia University Irving Medical Center used PET scanning to assess abnormal energy metabolism in the hearts of young patients with fatty acid metabolism disorders. They found that affected children have a diminished capacity to use fatty acids and experience metabolic crises if untreated.
