to find the dietry substance that was lacking in a disease‚ namely‚ rickets‚ the childhood form of osteomalacia. 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

They made this observation by introducing 24 candidate genes into mouse embryonic fibroblasts from Fbx15ßgeo/ßgeo embryos by retroviral transduction

The word melanoma comes from the Greek words‚ melas (black) and -oma (tumour). 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

Genetically modified ingredients can cause cancer. A consultant histopathologest at Aberdeen Royal Infirmary‚ Dr Stanley Ewen‚ raised the concern that food and water contaminated with genetically engineered material could increase the growth of malignant tumours upon contact with humans. Later‚ other studies suggested a link between engineered food and cancer. 3. It could raise new allergy outbreaks in humans. It was found that a genetically engineered soya bean containing Brazilian nut protein was allergenic
