Unraveling the path of infection using classical evolutionary biology techniques and modern genetic sequencing is a method that is increasingly being used in criminal and civil investigations. It is known as phylogenetic analysis but, unlike DNA tests, which are very common in legal proceedings, these results are rarely 100% conclusive.
The common cold is a viral disease of the upper respiratory tract, in most cases caused by rhinoviruses A, B and C. And the curious thing is that, despite being the most common infectious disease in humans, at the moment there is no known cure.
About 70 percent of emerging viral diseases in humans such as HIV, Ebola or the flu are animal-specific infections that can also affect our body. There are some 5,500 different known species of mammals, which in turn, can harbor countless microbes, so the exact number of viruses that haunt us is still an enigma for science.
Circumcision dramatically alters the penile microbiome, changes that could explain why this practice offers protection against HIV and other viral infections. This is what can be deduced from a study that has just been published by mBio, an open access journal of the American Society for Microbiology.
A team of American scientists claims that they have managed to cure an HIV-infected baby by initiating aggressive antiretroviral treatment in the first 30 hours of life. As the New York Times newspaper reported on Sunday and the SINC agency echoes today, the rapid treatment received by the newborn is "something that normally does not happen, but, if more studies prove its usefulness, it could be recommended as a global strategy ”. Until now, only one case of HIV cure in an infected adult, Timothy Brown - known as the Berlin patient - was known, thanks to a bone marrow transplant following leukemia.
A picture is worth a thousand words. That is the philosophy of The Self Assembly Line: From Chaos to Order, an interactive sculpture that helps to understand the self-assembly process of viruses. We show it to you in this
The disease was first identified in 1968. It is caused by the Norwalk virus, a small, highly infectious virus that is transmitted especially in times of extreme cold and causes abdominal cramps, fever, explosive diarrhea, and vomiting. Symptoms usually resolve within 24/48 hours. It parasitizes the small intestine by widening the intestinal villi and decreases the motility of the stomach.
Cells, viruses, microstructures ... with the naked eye we cannot distinguish anything, but if we enlarge the image we will find a fascinating universe. We show it to you in this photo gallery.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
