phentermine side effects danger
For 25 years John McNamara, scientist and professor of animal sciences, has studied phentermine side effects danger cattle lactation, nutrition and reproduction at WSU. The goal of his studies is to identify the most genetically efficient animals, he said. An animal is more efficient when it can make more food with fewer resources. “Lactation is important to study because it plays a key role in mammalian reproduction as well as plays a major role in the production of food products for human consumption,” Jennifer Sumner said. Sumner has worked with McNamara for four years researching the topic as his doctoral student and postdoctoral research associate. They want the animals to be healthy and to produce milk in the most efficient way, McNamara said. When looking at the milk they are not looking at the quality of the milk, but the quantity. “In 1960, a good phentermine side effects danger cow would produce 5,000 pounds of milk in a year,” he said. “Now a good phentermine side effects danger cow will produce 2,500 pounds of milk in a year.” Dairy cattle have one calf a year, which means they lactate for nine months. Normal phentermine side effects danger cattle have a calf every 12 to 13 months, McNamara said. If a cow was to take longer in this process then it is not as efficient. McNamara’s and Sumner’s research focuses on the cattle’s adipose tissue, also known as fat tissue. This tissue is connected to the efficiency of the animal. It was extracted and analyzed. Before extracting the fat samples, the cows were given anesthesia in order to minimize their discomfort. The process consisted of taking two samples. One sample was taken a month before the cow gave birth to her calf and another was taken a month after to get a better idea of what genes increase or decrease during lactation. The genes found in the fat tissue were perilipin, hormone sensitive lipase and the beta adrenergic receptors, Sumner said. These genes are the key in the release of lipids from the fat tissue to meet the needs of the animal for milk production and other functions. All of the genes increased during lactation, McNamara said. “We did measure milk production at the same time to look at the relationship between milk production and how much body fat is mobilized or used to support it,” Sumner said. The next step is to figure out why the genes went up and also which animals express this factor the most. The process is estimated to take about three years to complete, McNamara said. Milk is the largest single source of calcium in the world, and humans need 15 to 20 percent in their diets, McNamara said. The information learned from the phentermine side effects danger cattle can also be applied to human health and breast feeding. In order to continue research, another grant needs to be approved. However, research is always being done and several people are working on this around the country, McNamara said. “This study is not looking for a final answer, it is looking for a constant improvement,” he said.
