24. Biomedical Engineers and Cancer

24. Biomedical Engineers and Cancer Video Clips. Duration : 47.95 Mins.

Frontiers of Biomedical Engineering (BENG 100) Professor Saltzman uses cancer diagnosis and treatment as an example to demonstrate the some applications of biomedical engineering technologies and methods. Some issues involved in cancer treatment, such as tumor angiogenesis, radiation sensitivity, drug localization, and cancer stem cells are mentioned. Next, he describes the phases (I-IV), in compliance to guidelines enforced by the Food and Drug Administration (FDA), which a new drug compound must go through to gain approval prior to public distribution/sale. Finally, Professor Saltzman draws attention to the areas that biomedical engineers may contribute to, to improve this process. 00:00 - Chapter 1. Introduction to Cancer 03:56 - Chapter 2.

Make Glass Mirrors with Silver Nitrate

Make Glass Mirrors with Silver Nitrate Tube. Duration : 2.43 Mins.

How to make a mirror silvering solution from silver nitrate, ammonia, sugar and sodium hydroxide. Glass surfaces can be given coatings of silver that make them into mirrors. WARNING: Perform the whole experiment in less than two hours. This is because the solution generates extremely dangerous/explosive silver nitride on standing. Also, the solution will give off ammonia when heated so you'll need to do this outside, in a fume hood or in a well-ventilated area. And wash away all chemicals with lots of water. To do this, you first need the silver nitrate we made in a previous video: www.youtube.com Get one gram of silver nitrate and one gram of sodium hydroxide. Then add enough water to both to completely dissolve them. Mix them together and you'll get a black precipitate of silver oxide. Then add enough ammonia to completely dissolve the silver oxide. Add four grams of sugar and mix well. The solution will deposit silver coatings when its heated. If you heat it in a glass container it will deposit silver on the inside of the container. To deposit it onto a glass pane you can put the glass into a tray with solution and heat the tray from below. But do not let the solution boil. Boiling tears the silver off the surface. Thin layers of silver can be wiped off with a cloth if the silver goes where you don't want it. Thicker layers can be removed by applying hydrochloric acid. This process produces a back reflective mirror, which is what most household mirrors are. For more ...

1/3 THE GERSON MIRACLE (2004) - [Eng. Captions]

1/3 THE GERSON MIRACLE (2004) - [Eng. Captions] Video Clips. Duration : 30.88 Mins.

Lista de Reprodução: www.youtube.com _______________ O documentário "O milagre Gerson" narra a saga do médico alemão Dr. Max Gerson (1881-1959), que desenvolveu, no início de século 20, uma terapia para tratamento de praticamente todas as doenças. Ele emigrou para os EUA na década de 30, fugindo à perseguição dos judeus que aprisionou e executou seus 7 irmãos. Nos EUA seu método de cura foi atacado e visto com ceticismo pelo National Cancer Institute (NCI), uma organização cada vez mais suspeita de ligações com os interesses bilionários dos carteis farmacêuticos. A "Industria do Câncer" movimenta cerca de 200 bilhões de dólares por ano (dados de 2004). O Dr. Max Gerson foi, em 1958, vítima de roubo do manuscrito do livro que estava escrevendo e ao mesmo tempo vítima de envenenamento, quase fatal. Recuperado, reescreveu seu livro mas foi novamente envenenado em 1959 indo a falecer aos 78 anos. O livro foi posteriormente publicado por sua filha Charlotte: "Max Gerson MD, A Cancer Therapy: Results of 50 Cases". Sua filha Charlotte levou adiante seu trabalho e tendo sido proibida de criar um centro de tratamento nos EUA, fundou uma clinica em Tijuana, Mexico em 1977, onde milhares de pacientes tem sido curados de uma enorme variedade de enfermidades, incluindo câncer. A terapia Gerson atua nas duas causas básicas de doenças; deficiência de nutrientes e excesso e intoxicantes. O documentário mostra como ocorre uma constante perseguição pelo governo dos EU sobre todas as ...

Organic Materials That Melt by Light Irradiation (Observation by Polarizing Optical Microscope)

Organic Materials That Melt by Light Irradiation (Observation by Polarizing Optical Microscope) Tube. Duration : 1.45 Mins.

AIST has developed organic materials that melt from solid to liquid with only the light irradiation, without heating, and can be restored to their original solid state. Although photoisomerization takes place in solution, it is thought to rarely occur in crystals. The newly synthesized organic compounds have molecular weight of about 1100-1700 and undergo photoisomerization even in crystals. This is an important discovery concerning the basic concept of the melting phenomenon of matter. The next objective is to explore the possibilities for various applications, including photolithography.

Accelerating Scientific Discovery using Electron Microscopy and Molecular Modeling

Accelerating Scientific Discovery using Electron Microscopy and Molecular Modeling Tube. Duration : 70.35 Mins.

Computational screening is the name given to the computer docking of three-dimensional models of drug-like compounds into models of potential drug targets, usually proteins. Clearly, this computational method is far faster and cheaper than actually testing tens of thousands of potential drugs, which has been a standard in the pharmaceutical industry for generations. The rate limiting computational step however, and in the inner loop of the search, is the accurate computation of molecular configuration dependent relative binding affinities. In this two part talk I shall first describe a combination of image processing, and computational geometry algorithms to efficiently 3D reconstruct multi-resolution structure models of target proteins, nucleic acids from Electron Microscopy. These targets are culpable in the spread of viral infections (eg HIV). Next, I shall describe how multi-resolution molecular structure models are utilized to develop biophysical models of molecular-molecular (recognition) interaction. Namely, I'll describe (1+epsilon) linear time approximation algorithms for molecular energetics, based on the fast multipole, and the use of non-uniform fast Fourier transform, coupled to O(1) time spherical neighborhood search data-structures, that effectively yield near optimal for lead solutions in computational screening. These algorithms for target elucidation and computational screening are encapsulated with our freely available software called TexMol and VolRover.

40x-2000x Binocular Biological Compound Microscope Overview

This is a brand new, factory sealed, Variscope Series 8621 microscope. The Variscope microscope family of optical instruments is made by one of the largest "private label" optical component fabricators in the world. Included with the quadruple nosepiece are four achromatic multi-coated objective lenses that display a true-color image. You get 4x, 10x, spring loaded 40x, and spring loaded oil immersion 100x objectives included with this microscope. For viewing, we provide two sets of eyepieces: a pair of premium grade wide-field 10x (18mm) eyepieces and a second set of 20x eyepieces. This allows for magnification ranges of 40x, 80x, 100x, 200x, 400x, 800x, 1000x, and 2000x. Ergonomic features include an advanced Seidentopf-type microscope head to provide maximum comfort in adjusting interpuplillary distance. The microscope head swivels 360 degrees and sits at a 30 degree incline. The eyepieces have diopter focusing adjustments. The independent coarse and fine focusing knobs are on both the right and left side of the instrument. Unlike cheap models with simple slide clips, this microscope has a 115mm x 125mm stage with a fully mechanical X-Y axis slide holder so slides can be moved on the stage with fine precision, no fumbling the slide under clips. There is a graduated scale printed on the slide holder to allow you to maintain a record of the location of various structures on a particular slide. This microscope has a built-in 20 watt halogen bulb, with adjustable intensity light controls. Beware of cheaper models that use a tungsten bulb or have a simple on/off switch with no brightness controls. The microscope has a built-in spiral-type N.A. 1.25 Abbe condenser under the stage with an iris diaphragm. This advanced condenser gives you incredible control over the amount and focal length of light aimed at your specimen and is critical for high-powered magnification viewing. A swing-out filter holder is included as are a set of blue and green viewing filters.
