equator. An explanation for this is that sunlight is rich in Vitamin D and there is more sunlight near the equator, compared to areas further away from the equator. This research implies that lack of Vitamin D may be responsible for the onset of MS. If a person is deficient in Vitamin D, they may have a greater chance of getting this disease. A key area of interest in patients with MS is whether or not additional doses of Vitamin D supplements will help alleviate some of the symptoms, which…

has low blood calcium levels the parathyroid gland will act and secret PTH which will activate osteoclasts. The osteoclasts will help break down the bone and release the calcium from the bones to the blood stream. While it will also activate vitamin D which will help increase the absorption of calcium from the kidneys and intestines. Therefore, the body will keep the calcium in the blood instead of throwing it out through urine or stool. If the case was the opposite and the blood…

Paget’s disease of bone is a rather uncommon condition that effects less that 1% of the population of the United States, often presenting with no symptoms or discomfort what so ever. It isn’t known what specifically causes this disease, but it is speculated that heredity plays a big part. Paget’s disease of bone is typically pretty manageable when symptoms do present themselves with a variety of pharmaceutical remedies. Paget’s Disease of Bone Paget’s disease of bone is basically…

affect children all around the world. During the 1940s, rickets was nearly eradicated because doctors found that the cause of rickets was vitamin D deficiency. Between 1896 and 2000 less than one third of children that…

Jergens Natural Glow Instant Sun As someone who has always felt the need to be tanned (because it makes me feel better about myself) I've tried a lot of different methods... 1. Natural sun: baby oil, olive oil, no oil then shower then put oil on to lock the sun in, beer, reflective sheet, laying by water, floating in water, some SPF, no SPF, etc 2. Tanning beds: cheap tanning lotions, expensive lotions, no lotion, those that tingle, those that don't, mixing up to 7 different lotions because…

72% of the calcium in the U.S. food supply comes from milk and other dairy products. Aside from that, milk has the basic nutrients and is an important source of protein, and it’s thought to be the ‘perfect’ food. As a result, many consider milk a necessary and healthy part of every individual's diet, but that’s not necessarily true. While milk does offers many nutritional benefits, research has proven that milk, and other dairy products, are bad for one’s health. Consumption of milk can lead to…

Introduction Vitamin D is a group of fat-soluble secosteroids which is responsible for improving the intestinal absorption of inorganic ions such as calcium, zinc, iron, and magnesium, phosphate. Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol) are most vital compounds in the human being. Vitamin D is not actually a vitamin, but a steroid hormone formed in the body when the skin is exposed to sunbeams, mainly ultraviolet B light (UVB) rays22. The compound vitamin D has been found in…

family which can be a risk factor. Osteoporosis mainly depends on the BMD, and the regulation of the BMD is affected by genes. Therefore, osteoporosis is affected by genes. Some of the genes that are associated with causing osteoporosis are the vitamin D receptor, alpha collagen gene and estrogen receptor. Moreover, osteoporosis can result from a mutation in a single gene. However, osteoporosis is rarely caused by a…

Social concerns of humanity in Bicycle Thief The most significant events in cinema and art in the early 1940s were the emergence and rapid development of the Italian neorealism. Moreover, it was one of the most striking and perhaps the first major artistic phenomenon of the post-war years, not only in Italy but also all over the world. Neorealism as a movement, which arose in post-war time, offered a close look into the everyday life of ordinary people. Originating in the wake of the resistance…

The hypothesis is that depigmentation of the skin occurred by selection because of the decreased UVR to promote synthesis of vitamin D. The synthesis of the pre vitamin D3 occurs through photosynthesis. Darkly pigmented skin slows the process of vitamin D3 production. Depigmentation evolved to allow vitamin D3 synthesis outside tropical regions away from the equator. Depigmentation is the lightening of the skin to permit higher synthesis of vitamin D3. There is a requirement of vitamin D3 in low…
