Researchers seek cure to herpes virus in horses

Researchers seek cure to herpes virus in horses | Virus Chaser | Scoop.it
For a human, developing a cold sore is a minor, if irritating, inconvenience. But if a horse contracts that same virus, it can mean a death sentence.

Researchers are hopeful that a chemical compound, derived from a micro-algae known as dinoflagellate, will successfully fight the virus in horses. The algae, isolated from sediments off the coast of Bermuda, are grown on-site at the MARBIONC culture facility, populating over time in large glass containers of liquid. They’re microscopic, visible to the naked eye only when populations are dense enough to change the color of the liquid. Once the algae are mature, researchers harvest the organisms and extract chemical compounds from individual samples, then isolate the compound containing the anti-viral activity.

I like that: using easily-cultured microalgae to make an antiviral compound.

Of course, they could go one step further: use said microalgae to make one of the viral antigens - like gD - to act as a vaccine.

Going green: the sensible thing to do.

UCLA researchers' smartphone 'microscope' can detect a single virus, nanoparticles

UCLA researchers' smartphone 'microscope' can detect a single virus, nanoparticles | Virus Chaser | Scoop.it

Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.

 

Aydogan Ozcan, a professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, and his team have created a portable smartphone attachment that can be used to perform sophisticated field testing to detect viruses and bacteria without the need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.

 

"This cellphone-based imaging platform could be used for specific and sensitive detection of sub-wavelength objects, including bacteria and viruses and therefore could enable the practice of nanotechnology and biomedical testing in field settings and even in remote and resource-limited environments," Ozcan said. "These results also constitute the first time that single nanoparticles and viruses have been detected using a cellphone-based, field-portable imaging system."

 

In a paper published in ACS nano, Ozcan details a fluorescent microscope device fabricated by a 3-D printer that contains a color filter, an external lens and a laser diode. The diode illuminates fluid or solid samples at a steep angle of roughly 75 degrees. This oblique illumination avoids detection of scattered light that would otherwise interfere with the intended fluorescent image.

 

Using this device, which attaches directly to the camera module on a smartphone, Ozcan's team was able to detect single human cytomegalovirus (HCMV) particles. HCMV is a common virus that can cause birth defects such as deafness and brain damage and can hasten the death of adults who have received organ implants, who are infected with the HIV virus or whose immune systems otherwise have been weakened. A single HCMV particle measures about 150–300 nanometers; a human hair is roughly 100,000 nanometers thick.

In a separate experiment, Ozcan's team also detected nanoparticles — specially marked fluorescent beads made of polystyrene — as small as 90–100 nanometers.

 

To verify these results, researchers in Ozcan's lab used other imaging devices, including a scanning electron microscope and a photon-counting confocal microscope. These experiments confirmed the findings made using the new cellphone-based imaging device.
