At least in the laboratory‚ fibers in amla help reverse the effects of excessive consumption of fructose. Amla against osteoporosis. Scientists at the Ferrara University in Italy have found that amla extracts slow the activity of osteoclasts‚ the cells that break down bone.Since osteoporosis is a process of osteoclasts (bone busters) outpacing osteoblasts (bone

June 2010 Hirschsprung’s Disease Hirschsprung’s Disease was named after Harold Hirschsprung‚ a Danish physician‚ in 1886. It is a congenital disorder which means it is present at birth. It is an enlargement of the colon where ganglion cells‚ or nerve cells‚ are not present. This results in improper movement of the muscles in the bowel causing chronic constipation. The only certain method of diagnosis is a rectal biopsy. We will explore the symptoms‚ causes‚ and treatments of this disease. The

Anemia is a disease state that is characterized by a reduction of hemoglobin (Hb) or volume of red blood cells (RBC’s). The reduction in Hb or RBC’s leads to diminished oxygen carrying ability of the blood. Many forms of anemia exist – the anemias discussed will be relevant to our patient‚ JJ‚ based on her signs/symptoms and past medical history (PMH). Anemia can be classified based on the appearance or size of the RBC. The size of the RBC can be determined by either calculating the mean corpuscular

In international and professional level competition‚ athletes require a high level of skill and expertise. Athletes at this level would need to train for several years to get to where they are‚ and sometimes it is still not enough to get the winning medal. When you are representing your country and you have countless fans depending on your performance‚ the pressure adds up. What if they had the opportunity to obtain an unfair but promising advantage over their competition? Morals and values may push

Biochemistry will help medical technologists understand physiological disorders and diseases. In biochemistry we study about the cell it’s parts‚ functions and chemical reactions‚ a medical technologists should understand the cell because it is the cell‚ which is being observed whenever someone is trying to figure out what is

The N stands for Nano technology. We will have tiny devices the size of blood cells that go inside our body to keep us healthy. They will go in our brain and will interact with your biological neurons and allow us to merge with non-biological intelligence. Some scientists are Building Nano devices at the moment. They have made a design that if you replace a proportion of red blood cells with certain robotic cells‚ you could do an Olympic sprint for 15 minutes without taking a breath‚ or swim

Human Biology Unit 2 Assignment Aim: Carry out an experiment to measure the heart rate and ventilation rate before‚ during and after moderate exercise. Introduction: I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise

and help to control sugar level of blood. Moreover‚ green tea restrains the digestion of fat and reduces the amount of fat in the body. The second benefit of green tea is it helps to resist the oxidation. Mckay and Blumberg (2002) found that green tea has polyphones‚ which are the antioxidants that have the capability and power more than any antioxidants (pp.1-13). As a result‚ green tea reduces the risk of cancer and helps the body to resist the cancer cells. In addition‚ green tea also contains
