Abstract: Need for the study: Oral precancerous lesions are one of the most prevalent lesions worldwide today. Leukoplakia is the commonest premalignant lesion ‚ which if neglected can be fatal. Several therapeutic agents have been tried to intervene. Of which‚ Lycopene has been tried‚ tested and accepted as a conventional form of treating leukoplakia. Curcumin‚ 1‚7-bis-(4-hydroxy-3-methoxyphenyl)-1‚6- heptadiene-3‚5-dione] is regarded as the most biologically active constituent of the spice turmeric

Citric acid cycle From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search [pic] [pic] Overview of the citric acid cycle The citric acid cycle — also known as the tricarboxylic acid cycle (TCA cycle)‚ the Krebs cycle‚ or the Szent-Györgyi-Krebs cycle‚ [1][2] — is a series of enzyme-catalysed chemical reactions‚ which is of central importance in all living cells that use oxygen as part of cellular respiration. In eukaryotic cells‚ the citric acid cycle occurs in the matrix of the mitochondrion

Defn:Dengue Haemorrhagic Fever(DHF) are acute febrile diseases transmitted by mosquitoes‚ which occur in the tropics‚ can be life-threatening‚ and are caused by four closely related virus serotypes of the genus Flavivirus‚ family Flaviviridae.It was identified and named in 1779. It is also known as breakbone fever‚ since it can be extremely painful. Causative Agent: . Dengue is transmitted to humans by the Aedes (Stegomyia) aegypti or more rarely the Aedes albopictus mosquito. The mosquitoes that

Will Cell Biology 241 3/19/12 Natural Killer Cells Despite their infuriated name‚ natural killer cells are literally a very important type of cell in the human body. Natural killer cells‚ also known as NK cells‚ are primarily a supportive type of cell which aids in protecting you from distinct infections and even cancer‚ as these cells target tumor cells.1 The natural killer cell plays a severe role in administering the innate and adaptive immune response to pathogens‚ injury‚ and stress.

module 3 ematology – Module 3‚ Lecture 1 Slide 1 ● The first type of blood cells that we will focus on are the erythrocytes‚ also called the red blood cells. These are the cells that transport oxygen in the blood from the lungs to the tissues. These cells also help transport some of the carbon dioxide from the tissues to the lungs. The main function of erythrocytes‚ namely oxygen transport‚ is carried out by the protein that makes up the majority of the protein composition of the cell

Recent advances in technology permit measurement of characteristics of the nerve fibres that make up the optic nerve. One of these is SD-OCT(Fig2)‚ a non contact‚ non-invasive method that enables physicians to obtain in vivo‚ high resolution (upto 5 microns) cross-sectional images of the retina. It is based on principle of low-coherence interferometry(Fig 3). By imaging a 3D cube of data it allows a detailed evaluation of the peripapillary area.

Multiple myeloma Multiple myeloma (also plasma cell myeloma also known as MM‚ myeloma‚ plasma cell myeloma‚ or as Kahler’s disease) is a progressive hematologic (blood) disease. It is a cancer of the plasma cell‚ an important part of the immune system that produces immunoglobulins (antibodies) to help fight infection and disease. The immune system is made up of several types of cells that work together to fight infections. Lymph cells (called lymphocytes) are the main type of cell in the adaptive

It is often thought that whooping cough is an outdated disease‚ due to the many ways we now have to combat the pathogen‚ but every year almost 400‚000 people die due to infection with Bordetella pertussis (1‚ 41). Bordetella pertussis is a gram-negative coccobacillus bacterium‚ which causes whooping cough in humans (1‚ 41). The bacterium is spread by air borne particles or mucus droplets and is highly contagious. Although there is no known reservoir for the pathogen humans can often be asymptomatic
