Geranium extracts inhibit HIV-1

Scientists from the Helmholtz Zentrum München demonstrate that root extracts of the medicinal plant Pelargonium sidoides (PS) contain compounds that attack HIV-1 particles and prevent virus replication. A team spearheaded by Dr. Markus Helfer and Prof. Dr. Ruth Brack-Werner from the Institute of Virology and Prof. Dr. Philippe Schmitt-Kopplin from the Analytical BioGeoChemistry research unit (BGC) performed a detailed investigation of the effects of PS extracts on HIV-1 infection of cultured cells. They demonstrated that PS extracts protect blood and immune cells from infection by HIV-1, the most widespread type of HIV. PS extracts block attachment of virus particles to host cells and thus effectively prevent the virus from invading cells. Chemical analyses revealed that the antiviral effect of the PS extracts is mediated by polyphenols. Polyphenol mixtures isolated from PS extracts retain high anti-HIV-1 activity but are even less toxic for cells than the crude extract.

Western U.S. drought puts big strain on reservoirs

Western U.S. drought puts big strain on reservoirs | Online Human Biology CCC | Scoop.it
Watch the video Western U.S. drought puts big strain on reservoirs on Yahoo News . Satellite photos show the Colorado River, which feeds Nevada's Lake Mead, is drying up, meaning the lake is rapidly shrinking. The lake provides water for 20 million people in southern Nevada, southern California and Arizona -- and it's lost 4 trillion gallons of water since 2000. Ben Tracy reports.

Beijing smog contains witches' brew of microbes

Beijing smog contains witches' brew of microbes | Online Human Biology CCC | Scoop.it

For people racked by the dreaded ‘Beijing cough’, it is all too clear that particles in the city’s thick smogs pose a public-health problem. But much less clear is the impact — or even the identity — of the microbes that also drift through the brown haze.

 

Chinese researchers have now used genome sequencing to identify about 1,300 different microbial species in an exceptionally soupy smog that hit Beijing in January 2013 (ref. 1). Reassuringly, most of the microbes they found are benign — but a few are responsible for allergies and respiratory disease in humans. And on days with heavier pollution, the proportion of DNA from these allergens and pathogens increased, suggesting that they might present an additional health threat to vulnerable groups, such as older people or those with weakened immune systems.

Normally we think of microbes on surfaces, but air laced with bacteria and more requires a new way of thinking!

Robert DesJarlait's curator insight, June 27, 2013 9:14 AM

According to a CNN article, the American Cancer Society estimates that men have about a 1 in 2 chance of developing cancer at some point in their lives, compared with women, who have a 1 in 3 chance. The current odds border on an epidemic level, an epidemic level that some commentators have referred to as "the quiet epidemic." More and more studies reveal that environmental factors play a strong role in the development of cancer. Extractive resource industries for oil, energy, and mining release toxins and pollutants into our air and into the land and waters. Is anyone connecting the dots here? Smoking and poor diets are primary factors for cancer, but we can't turn a blind eye to the end result of ecocide. Obviously, one of the end results of ecocide are higher rates of cancer.
