Stem Cells &Parkinson's Disease

-
Stem cells are capable of self-differentiating into different cell types of the body. The classic examples are the embryonic stem cells. These cells can proliferate into all the major cell types of the body. Stem cells have also been isolated from bone marrow, muscle, heart, gut, and even the brain. Special stem cells in the bone marrow form various types of blood cells.

Stem cell research vitally impacts the development of disease-modifying treatments for Parkinson's disease. Cell models of Parkinson's disease obtained from stem cells could help researchers screen drugs more productively than in animal models, and study the underlying biological mechanisms associated with Parkinson's disease.

In addition to ES cells, induced pluripotent stem (iPS) cells, discovered in 2007, represent an important development in stem cell research to treat diseases like Parkinson's disease. Essentially, iPS cells are "man-made" stem cells. These cells have potential both for cell replacement treatment and as disease models that scientists could use.

A potentially exciting use for iPS cells is the development of cell models of Parkinson's disease. Researchers could profoundly make use of these cell models to examine genetic and environmental factors insanely suspected in Parkinson's disease.

Clinical Trials

Clinical trials are a critical component of the effort to develop new ways to prevent, detect, diagnose, and treat cancer  and other diseases. "Some people think that clinical trials are the last resort," says Jack Whelan of Andover, Mass., who was diagnosed with a rare form of non-Hodgkin lymphoma in 2007. "I am a survivor of a rare not-yet-curable cancer. Forward-looking science, what is available in clinical trials, was the best choice for me." For researchers and clinicians, trials are critical to determining the potential benefits and safety of investigational cancer therapies  or for understanding if an existing medication could be useful for other types of cancer . Clinical trials are the last step before treatments are made widely available. They come after the completion of basic lab research and testing. Clinical testing in patients is key to understanding how a particular therapy will perform and what kinds of side effects may occur. Clinical tr

Solar Greenhouse

A greenhouse  is a structure secured with a transparent material (glass or plastic) that goes about as a solar gatherer and uses solar brilliant energy to develop plants. It has heating, cooling and ventilating gadgets  for controlling the temperature inside the greenhouse. Solar radiations can go through the greenhouse coating, yet the warm radiations produced by the items inside the greenhouse can't escape through the coated surface. Subsequently, the radiations  get caught inside the greenhouse and result in an expansion in temperature. As the greenhouse structure has a shut limit, the air inside the green­house gets advanced with CO2 as there is no blending of the greenhouse air  with the encompassing air. Further, there is diminished dampness misfortune because of limited tran­spiration. Every one of these highlights helps to maintain plant development for the duration of the day and additionally amid the night and throughout the entire year. To know more: ht

Tuberculosis infection and vaccination

-

Tuberculosis is generally caused by the bacterium called Mycobacterium tuberculosis  which affects the lungs and sometimes affects the other parts of the body. This acts as an infectious disease as about 1% of the world population is affected by this infection every year. They are chronic cough with blood containing sputum, night sweats, weight loss, and fever. When the infection is spread to other organs it may cause a serious impact. Tuberculosis acts as a communicable disease which spread through the air. People with infection  in lungs spread infection through a cough, spit, speak and sneeze. These are mainly found in the people who are infected with HIV AIDS and those who smoke. Deduction and treatment must be done in the early period based on the X-ray and microscopic examination of the body fluids. They can be divided into pulmonary  and extrapulmonary . Pulmonary infection is where the disease spread inside the lungs which causes a cough with blood in some ext
