Sangeeta N. Bhatia
Sangeeta N. Bhatia (born 1968) is an American biological engineer and the John J. and Dorothy Wilson Professor at MIT’s Institute for Medical Engineering and Science and Electrical Engineering and Computer Science (EECS) at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts, United States. Bhatia's research investigates applications of micro- and nano-technology for tissue repair and regeneration. She applies ideas from computer technology and engineering to the design of miniaturized biomedical tools for the study and treatment of diseases, in particular liver disease, hepatitis, malaria and cancer. In 2003, she was named by the ''MIT Technology Review'' as one of the top TR100, 100 innovators in the world under the age of 35. She was also named a "Scientist to Watch" by ''The Scientist (magazine), The Scientist'' in 2006. She has received multiple awards and has been elected to the National Academy of Sciences, the National Academy of Engineering, ...

Nanotechnology
Nanotechnology, also shortened to nanotech, is the use of matter on an atomic, molecular, and supramolecular scale for industrial purposes. The earliest, widespread description of nanotechnology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macroscale products, also now referred to as molecular nanotechnology. A more generalized description of nanotechnology was subsequently established by the National Nanotechnology Initiative, which defined nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). This definition reflects the fact that quantum mechanical effects are important at this quantum-realm scale, and so the definition shifted from a particular technological goal to a research category inclusive of all types of research and technologies that deal with the special properties of matter which occur below the given size threshold. It is therefore commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaria
Malaria is a mosquito-borne infectious disease that affects humans and other animals. Malaria causes symptoms that typically include fever, tiredness, vomiting, and headaches. In severe cases, it can cause jaundice, seizures, coma, or death. Symptoms usually begin ten to fifteen days after being bitten by an infected mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial resistance disappears over months to years if the person has no continuing exposure to malaria. Malaria is caused by single-celled microorganisms of the ''Plasmodium'' group. It is spread exclusively through bites of infected ''Anopheles'' mosquitoes. The mosquito bite introduces the parasites from the mosquito's saliva into a person's blood. The parasites travel to the liver where they mature and reproduce. Five species of ''Plasmodium'' can infect and be spread by h ...

Artificial Organs
An artificial organ is a human made organ device or Tissue (biology), tissue that is Implant (medicine), implanted or integrated into a human — interfacing with living tissue — to replace a natural Organ (anatomy), organ, to duplicate or augment a specific function or functions so the patient may return to a normal life as soon as possible. The replaced function does not have to be related to life support, but it often is. For example, replacement bones and joints, such as those found in hip replacements, could also be considered artificial organs. Implied by definition, is that the device must not be continuously tethered to a stationary power supply or other stationary resources such as filters or chemical processing units. (Periodic rapid recharging of batteries, refilling of chemicals, and/or cleaning/replacing of filters would exclude a device from being called an artificial organ.) Thus, a Kidney dialysis, dialysis machine, while a very successful and critically importan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Broadcasting Service
The Public Broadcasting Service (PBS) is an American public broadcaster and non-commercial, free-to-air television network based in Arlington, Virginia. PBS is a publicly funded nonprofit organization and the most prominent provider of educational programming to public television stations in the United States, distributing shows such as ''Frontline'', '' Nova'', '' PBS NewsHour'', ''Sesame Street'', and ''This Old House''. PBS is funded by a combination of member station dues, the Corporation for Public Broadcasting, pledge drives, and donations from both private foundations and individual citizens. All proposed funding for programming is subject to a set of standards to ensure the program is free of influence from the funding source. PBS has over 350 member television stations, many owned by educational institutions, nonprofit groups both independent or affiliated with one particular local public school district or collegiate educational institution, or entities owned ...

Ultrasound Machine
Medical ultrasound includes diagnostic techniques (mainly medical imaging, imaging techniques) using ultrasound, as well as therapeutic ultrasound, therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g. distances and velocities) or to generate an informative audible sound. Its aim is usually to find a source of disease or to exclude pathology. The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography. The practice of examining pregnant women using ultrasound is called obstetric ultrasonography, and was an early development of clinical ultrasonography. Ultrasound is composed of sound waves with frequency, frequencies which are significantly higher than the range of human hearing (>20,000 Hz). Ultrasonic images, also known as sonograms, are created by se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
