ROLE OF VITAMIN D IN REGULATION OF SEVERAL GENES: The vitamin D hormones have essential roles in human health. Vitamin D hormones act by binding to and activating the vitamin D receptor (VDR) to regulate the expression of genes in a tissue-specific manner. Vitamin D hormones regulate blood calcium levels by controlling intestinal absorption of dietary calcium and reabsorption of calcium

There are many different types of relationships and interactions between organisms A wide array of interactions among plants‚ animals‚ and microorganisms occurs in nature. Some of these relationships are characterized by a close physical association among species that continues for a large period of the life cycle. In 1879 German botanist Heinrich Anton de Bary coined the term "symbiosis" to describe these relationships‚ meaning the living together of different species of organisms. Many people associate

Tissue engineering By Nathan. F Introduction Tissue Engineering is the use of a combination of cells‚ engineering and materials methods‚ and suitable biochemical and physio-chemical factors to improve or replace biochemical functions. The objective of tissue engineering is to create living body parts that will fully integrate with the recipient’s body. Tissue engineering mostly associated with applications that repair or replace portions of or whole tissues. For example bone‚ cartilage

It is a very serious cancer that most often occurs in the skin and less frequently in the eye or in the lining of the nose‚ mouth‚ or genitals. Melanoma begins in melanocytes‚ cells that make a pigment called melanin. Both light- and dark-skinned people have melanin‚ which gives colour to the skin‚ hair‚ and parts of the eye. The skin is the largest organ in the body‚ so it isn’t surprising that skin cancer is the most
