CDC - Seasonal Influenza (Flu) - Guidance for Clinicians on the Use of Rapid Influenza ... - 0 views

  • Sensitivities of RIDTs are generally 40-70%, but a range of 10-80% has been reported compared to viral culture or RT-PCR. Specificities of RIDTs are approximately 90-95% (range 85-100%). Thus false negative results occur more commonly than false positive results.

  • interest surrounded one particular form of bacteria whose DNA was less than 86 percent similar to previously existing forms

      That's crazy. It's difficult for me to fathom the implications of that big of a difference in DNA because even the DNA of humans and apes is 95-98% similar.
  • Lake Vostok, which is believed to have been covered by ice for more than a million years but has kept its liquid state

      I wonder how that works, that the lake can remain liquid yet all the surrounding water is frozen as ice?
  • Exploring environments such as Lake Vostok allows scientists to discover what life forms can exist in the most extreme conditions

      Maybe this new bacteria could be similar to the domain Archaea since it can survive in such extreme conditions.

  • The possibility that the lake existed had first been suggested by a Soviet scientist in 1957

      The intelligence of scientists always astounds me. Even back in 1957 when technology was not as advanced as it is now they were able to make amazing discoveries such as this.

Nanoparticles loaded with bee venom kill HIV - 0 views

shared by Katelyn Madigan on 08 Mar 13 - No Cached
  • ee venom contains a potent toxin called melittin that can poke holes in the protective envelope that surrounds HIV
  • When the nanoparticles come into contact with normal cells, which are much larger in size, the particles simply bounce off
  • an advantage of this approach is that the nanoparticle attacks an essential part of the virus' structure. In contrast, most anti-HIV drugs inhibit the virus's ability to replicate
  • ...1 more annotation...
  • The nanoparticles could be injected intravenously and, in theory, would be able to clear HIV from the blood stream

  • CONAN: Well, is there something that - some things that every hospital or every clinic should be doing in order to minimize the risk? PERENCEVICH: I think one of the most important things they can do is make sure their microbiology lab is able to detect these strains.

A viral grappling hook: Flu virus attacks like a pirate boarding party - 1 views

    The flu virus carries about 300 to 400 of these hooks and virologists had known that several are needed to fuse the membranes. 4 hooks has recently been identified as the number of hooks required to pull the two membranes together. Without the attachment of 4 hooks the virus is vulnerable to inhibitors which will prevent fusion.

Bacterial byproduct offers route to avoiding antibiotic resistance - 0 views

    Increasing ROS (reactive oxygen species) in bacteria allow current antibiotics to be more potent. This approach weakens the bacteria allowing lower doses of antibiotics to be effective. This is can potentially help reduce the rate of antibiotic resistance. As we continue to develop a greater understanding about disease causing bacteria we can expose numerous ways to weaken the bacteria.

    This puts a whole new light on 'spirit'!!! Sterilization is SO important!!! Other articles are saying that this competition and the arena -- "It's probably the best-scrubbed place in the county," she added. Cheerleading camps or competitions have been the source of previous outbreaks, including a 2002 E. coli O157:H7 outbreak in Eastern Washington. This is crazy!!! Person to person contact is inevitable in cheerleading camps and competition. Proves how important sterilization and handwashing is!!!
