Forscher entwickeln einen Schnelltest, der Malaria und andere tropische Krankheiten in einer einzigen Blutprobe diagnostiziert

Der Welt-Malaria-Tag am 25. April 2016 ruft eine weitverbreitete Krankheit in Erinnerung, die angesichts globaler Bedrohungen wie dem Ebola- oder dem Zika-Fieber häufig in Vergessenheit gerät. Die Diagnose von Malaria ist schwierig, da Fieber das vorwiegende Symptom zahlreicher tropischer Infektionen darstellt. Mit der CD-förmigen Plattform „LabDisk“ lässt sich nun eine einzige Blutprobe innerhalb von 60 bis 90 Minuten mithilfe bestimmter biochemischer Komponenten auf mehrere Erreger gleichzeitig testen. Wissenschaftlerinnen und Wissenschaftler unter der Leitung von Dr. Konstantinos Mitsakakis vom Institut für Mikrosystemtechnik (IMTEK) der Albert-Ludwigs-Universität und dem Freiburger Hahn-Schickard-Institut für Mikroanalysesysteme haben das Diagnosewerkzeug für Malaria und andere tropische Infektionskrankheiten entwickelt. Die Disk ist einfach und kostengünstig herzustellen, für ein tragbares Gerät ausgelegt und kann selbst von ungeschultem Personal direkt bei den Patientinnen und Patienten bedient werden. Damit ist sie besonders für den Einsatz in strukturschwachen Gebieten geeignet. Die LabDisk ist das Ergebnis des Projekts „DiscoGnosis“, das die Europäische Kommission mit 3 Millionen Euro förderte.

IBM’s SoftLayer cloud-enabled World Community Grid to provide free virtual supercomputer power to The Scripps Research Institute to speed screening of promising chemical compounds

ARMONK, NY & LA JOLLA, CA – 03 Dec 2014: Although some medical therapies show promise as treatments for Ebola, scientists are still looking urgently for a definitive cure.

For the first time, anyone with access to a computer or Android-based mobile device can help scientists perform this critical research — no financial contribution, passport, or PhD necessary. In fact, volunteers can be asleep, traveling or on a coffee break when they help researchers search for an Ebola cure. (more…)

Warmer temperatures push malaria to higher elevations

ANN ARBOR — Researchers have debated for more than two decades the likely impacts, if any, of global warming on the worldwide incidence of malaria, a mosquito-borne disease that infects more than 300 million people each year.

Now, University of Michigan ecologists and their colleagues are reporting the first hard evidence that malaria does—as had long been predicted—creep to higher elevations during warmer years and back down to lower altitudes when temperatures cool. (more…)

UCLA researchers create Google Glass app for instant medical diagnostic test results

A team of researchers from UCLA’s Henry Samueli School of Engineering and Applied Science has developed a Google Glass application and a server platform that allow users of the wearable, glasses-like computer to perform instant, wireless diagnostic testing for a variety of diseases and health conditions.

With the new UCLA technology, Google Glass wearers can use the device’s hands-free camera to capture pictures of rapid diagnostic tests (RDTs), small strips on which blood or fluid samples are placed and which change color to indicate the presence of HIV, malaria, prostate cancer or other conditions. Without relying on any additional devices, users can upload these images to a UCLA-designed server platform and receive accurate analyses — far more detailed than with the human eye — in as little as eight seconds.

UA Study’s Findings Key to Understanding Immunity as We Age

UA researchers have discovered that two separate defects combine to contribute to reduced T cell responses with aging.

Researchers at the University of Arizona College of Medicine – Tucson have found a key to understanding the aging immune system’s decreased response to infectious diseases, which remain among the leading causes of death in older adults.

Aging profoundly affects the immune system’s T cells – the types of white blood cells that defend against intracellular pathogens, such as viruses, intracellular bacteria or parasites, such as malaria. Newly encountered pathogens are attacked by what are known as naïve T cells, some of which then learn and remember, becoming memory T cells that prevent reinfection when they encounter the same pathogen again. But naïve T cells become depleted with age, leading to less effective immune responses against new infections. (more…)

Useful pesticides

We all know about the harm that can be caused by pesticides. While being misused, pesticides can have a negative impact on the plants, animals and human health. Animals that eat the treated with pesticides plants, have a small amount of pesticides left in their organisms. Being a food to a human, such animals represent a certain risk to human health. Not only the meat can be intoxicated with pesticides but also eggs, milk and the further products of milk production.

While working with pesticides, people accumulate them in the organism, what, in turn, may lead to the chronic diseases. Human needs have increased immensely, and people nowadays can’t eliminate the use of pesticides. (more…)

Breaking Dengue Fever

Like malaria, dengue fever is an infectious disease transmitted by mosquitoes. Unlike malaria, there is no vaccine for it. As many as 100 million people contract dengue each year, but MSU researcher Zhiyong Xi is working to change that.

Among the estimated 2.5 billion people at risk for dengue, more than 70 percent live in Asia Pacific countries, which spurred Xi to establish a collaborative research institute at Sun Yat-sen University in Guangzhou, China. (more…)

CAMBRIDGE, MA – 24 Jun 2013: The search for more versatile and less expensive materials for solar energy received a boost today as Harvard launched a free database that catalogues the suitability of 2.3 million organic, carbon compounds for converting sunlight into electricity.

Harvard’s Clean Energy project — which screened the molecules using World Community Grid, an IBM-managed virtual supercomputer that harnesses the surplus computer power donated by volunteers — is believed to be the most extensive investigation of quantum chemicals ever performed. (more…)
