OpenPCR – Du biohacking open source Par Korben Lorsqu’on souhaite séquencer des gènes, les cloner, diagnostiquer de l’ADN…etc, on utilise une ou PCR en anglais afin de répliquer de grosses séquences d’ADN, à partir d’un seul échantillon. C’est la quantité d’ADN manipulable qui va permettre aux scientifique de travailler sur certaines séquences bien précises. Pour cela, on utilise des machines capables de « copier » de l’ADN. Cela a permis par exemple à prouver que le poisson utilisé dans les restaurants japonais n’est pas toujours celui qu’on croit, à détecter la présence de certains virus comme le H1N1 ou le VIH, ou encore d’explorer votre propre génome pour par exemple découvrir que le dégoût que vous éprouvez pour les choux de Bruxelles est génétique. Pour comprendre comment ça marche, je vous renvoie vers cette animation . Une machine comme celle-ci coûtait jusqu’à présent plusieurs milliers d’euros. [ Source ] Vous avez aimé cet article ?
Triggertrap veut faire obéir votre appareil photo au doigt et à l’oeil [vimeo] Le créateur des bricolages photo les plus inventifs de l’internet est de retour avec Triggertrap. Vous ne pouvez pas encore l’acheter, mais vous pouvez déjà le soutenir. Le projet est présenté sur Kickstarter pour espérer récolter les 25.000$ de mise de fond nécessaires à la production du Triggertrap, un petit boitier de rêve à base d’Arduino pour les fans de photo créative. Le Triggertrap imaginé par Haje Jan Kamps et Ziah Fogel pourra déclencher des prises de vue sur l’interruption d’un faisceau laser, la détection d’un bruit ou sur une base temporelle pour du time lapse. Le boitier Triggertrap devrait sortir aux alentours de 75$ sous forme de produit fini, et pourrait aussi être proposé à assembler soi-même.
Genetics Course|Biology Course Summary This course is based on 7.03 Genetics, Fall 2004 made available by Massachusetts Institute of Technology: MIT OpenCourseWare under the Creative Commons BY-NC-SA license. This course discusses the principles of genetics with application to the study of biological function at the level of molecules, cells, and multicellular organisms, including humans. The topics include: structure and function of genes, chromosomes and genomes, biological variation resulting from recombination, mutation, and selection, population genetics, use of genetic methods to analyze protein function, gene regulation and inherited disease.

Gene Delivery: Tools of the Trade Genes can be delivered into a group of cells in a patient's body in two ways. The first, called in vivo (in VEE-voh), is to inject the vector directly into the patient, aiming to target the affected cells. The second, called ex vivo (ex VEE-voh), is to deliver the gene to cells that have been removed from the body and are growing in culture. Ex vivo approaches are less likely to trigger an immune response, because no viruses are put into patients. Bone marrow contains stem cells that give rise to many types of blood cells. Two Page Version, Dalhousie Immunology Bookcase The Two Page Version The immune system depends on the complex interaction between many diverse elements. It is important to remember that, although it is involved in a number of disease processes, the primary function of the immune system is to combat infectious agents. There are four major components of the immune system involved in fighting off pathogens: 1. Each of these components will be dealt with in detail in this textbook but their important functions are very briefly summarized below. Antibodies specifically bind to pathogens to bring them to the attention of other parts of the immune system (Complement and phagocytic cells). Complement refers to a cascade of small proteins that bind to pathogens and poke holes in their outer surface causing death (Appendix 2). T cells are referred to as CD4+ or CD8+ T cells based on their surface protein markers. Non-specific effector cells have a variety of functions.

Do You Want To Live Forever? Documentary | WatchDocumentary.Tv <a href=" feed</a> British biomedical gerontologist, Dr. Aubrey de Grey dispute one of the fundamental assumption about the human being, that aging is inescapable. Aubrey claims that aging is a disease that should be treated. Aging is damage, damage should be repaired. De Gray’s strategy demands determining every factors that cause human body to age along with developing treatments for every single of them. Humans have been seeking to claim that we can take control or stop getting old since the beginning of time. This documentary follows the radical life-extension as well as immortality concepts of Dr. Also watch Extraordinary People – A Hundred Orgasms A Day and Stress: Portrait of a Killer Watch Do You Want To Live Forever?
Trigger Trap: The Universal Camera Trigger by Ziah Fogel & Haje Jan Kamps SHIPPING: Please remember to add $5 to your pledge for postage to anywhere in the world. So, for the $75 option, please pledge $80 to ensure shipping is included. Thank you! UPDATE: When the project funds, the price of the Triggertrap will go up to $125 per unit. Kickstarter is your chance to get a 40% discount! Triggertrap is an open-source hardware project for photographers and geeks. The idea is simple: Create an universal camera trigger that makes it easy to trigger your camera any way you could possibly think of. Out of the box, Triggertrap will support being triggered by: LASER - someone breaks a laser-beam, the camera takes a picture. Oh, and because the Triggertrap will be optically isolated from the camera, the very worst that can happen (say, if you connect your Triggertrap to a 10,000 volt mains line, whether by dumb accident or - even dumber - on purpose), is that you blow up your Triggertrap device, whilst your camera stays safe.

Acute Oxygen Prescribing Oxygen therapy. Forever argued by opposing factions throughout the hospital. Traditionally the anaesthetists have always maintained the standpoint that hypoxia is far more detrimental than hypercarbia, and advocated the use of high inspired concentrations of oxygen, at high flows. Opposing this the physicians, particularly chest physicians, have always held firm the opinion that retention of CO2 in chronic type 2 respiratory failure is sufficiently serious an issue to warrant judicious use of oxygen therapy. Since 2008 there has finally been agreement following the publication of the British Thoracic Society Guideline on Emergency Oxygen Therapy in Adults. This guideline is a consensus statement from every royal society throughout the UK (medical, surgical, nursing, anaesthetic, O&G, paramedics, A&E) apart from paediatrics (They have their own guidance). We have a local implementation of this guideline, and you can download it here. Be Sociable, Share!
