Leptin

in recent times. This August, a team of scientists at the University of Montreal published data on a different animal study involving leptin, a hormone nicknamed the ‘satiety hormone’, which regulates energy stores and signals to the body when it has enough fuel and energy. Researchers concluded that it’s possible that when in the middle of a workout, one’s leptin levels fall, which could send a hunger signal to the brain’s pleasure signal in order to generate the rewarding effects of running. A…

“Obesity is not a disease but a physical manifestation of a history, our country had with hunger.” Epstein, Ethan. He believes that obesity is a free choice. Recent studies have shown that obesity has become an epidemic in the United States. “More than 65% of people in the United States are obese”, and millions of dollars are being spent on obesity” (National Institute of Diabetes and Digestive and Kidney Diseases). Insurance companies would not cover obesity because it was not considered a…

Obesity. Liver Disease. Diabetes. These are only three of the effect that sugar can have on the human body. Sugar can cause countless life threatening diseases, some more common than others. Sugar is something to be afraid of. The first example of something sugar can cause is liver diseases. Overloading the liver on sugar can progress to non-alcoholic liver disease or liver cancer. Secondly, if the pancreas is overworked by sugar intake, it could lead to a serious liver disease. Lastly, sugar…

of orexigenic and anorexigenic signaling to occur in the hypothalamus, or feeding stimulatory and inhibitory signaling, respectively. Leptin, a 16-kDa protein, serves as a critical element of this signaling system. This receptor affects neuropeptide Y, a common orexigenic signal, and anorexigenic signals such as corticotropin releasing factors. A decrease in leptin, the adiposity signal stimulated by fat tissue, causes an unbalanced shift of feeding feeding-regulatory circuitry in the…

and diabetes. One breed had a defect in fat cells that would produce and discharge leptin, a hormone. The other breed had a defect to their ability to respond to leptin and structure its actions. Leptin is important because mice and humans use this hormone to prevent overeating after a meal. The observations say that seeing obesity as a hormonal disorder is too superficial. Obese humans have a high amount of leptin and insulin. These hormones affect pathways of neurons in hypothalamus and…

America is a breeding ground of obesity in the late turn of the century. There are contributing factors that lead to this weight gain though. First, being the doubling in sizes at restraint before the early 1980s where everyone wanted to go big portion sizes were significantly smaller than they are nowadays. Stress is also an important factor most people work two jobs in this day and age. Which makes it to where we have less time to plan meals and more time to get processed food from…

Obesity is considered to be the condition in which an individual is grossly fat or overweight. Obesity is one of the main reasons why people die around the globe. At least 2.8 million adults die each year due to being obese (EASO). People consider fast-food to be the main reason why kids are obese but is it? There are many other important reasons that can also cause obesity leading to health problems or worse, death. Some we can control and turn around however, other reasons are born with you…

the child has, reverting back to the mother’s diet during pregnancy and before she gets pregnant. Developmental programming is the stress on the intrauterine environment from the mother’s diet, which causes the baby’s brain to create the hormone leptin which signals it to work for or against the fat cell quantity and its storage. Toxins in our environment can also have an impact on the fetal tissue…

For instance, leptin deficiency, which is known to be a genetic cause of obesity. Leptin is a type of hormone that is mainly produced in fat cells but is also produced in the placenta. Leptin regulates weight by informing the brain to eat less food when it knows that the storage of body fat is too high. If leptin is not informing the brain to eat less food or the body isn’t producing enough leptin, the control is gone, and obesity is taken place. The role of leptin is a replacement for the…

INTRODUCTION The nervous systems are developed by the proliferation of progenitors in the epithelium, the specification of neurons and glia, the growth and guidance of axons and dendrites, and the development and refinement of electrical and chemical synapses. In the central nervous system (CNS), stem cells reside throughout life in the forebrain, continuing to generate neurons and glia in the subventricular zone (SVZ) surrounding the lateral ventricle and in the dentate gyrus of the…
