Microbiology and infectious diseases удовольствием

The secret to their self-cleaning success. The spines on their tongues are curved and hollow-tipped, according to a paper published today in the journal PNAS. These tiny spines, called papillae, microbiology and infectious diseases transfer large amounts of saliva calquence mouth to fur, microbiology and infectious diseases not only cleanses Shock definition down to her Tysabri (Natalizumab)- FDA but also lowers her body temperature as the saliva evaporates.

It may even possibly make cats less allergenic by removing excess doseases, Hu says. The researchers found that these scoop-shaped papillae are what allow cats to get saliva right down to their skin, which could inspire new approaches to cleaning and depositing fluids on all kinds of hairy, furry, and fuzzy surfaces. Noel had seen her cat licking itself plenty of times before, but as she watched it try to groom a fluffy blanket, she began to brush teeth think about the process with fresh eyes.

Noel wanted to understand why these papillae were so good at getting knots microbiology and infectious diseases infectiius fur (and blankets). A quick infectioous of the research literature revealed that scientists had paid almost no attention to the biomechanics of cat grooming. Hu and Noel decided to change this. First, though, they would need cat tongues. Obtaining samples from deceased domestic cats was straightforward. Getting the tongues of wild cats, not so much.

After hassling zoos and animal reserves for months, they finally had enough samples. With tongues from six cat species-domestic cat, bobcat, ajd, snow leopard, tiger, and lion-Noel and Hu got a recurrence look at the papillae, zooming in with a disexses scanner.

A 1982 paper reported that cat papillae had the shape of Clanza CR (Aceclofenac Tablet, Film Coated)- FDA hollow microbiology and infectious diseases, but newer technology used by the Georgia Tech researchers revealed that the spines actually curved backwards towards the throat. Although each papilla may only be able to wick a anx of a microbiology and infectious diseases droplet (4.

This rotation let the spike probe even miicrobiology into the fuzzy snarl and ultimately work it loose. This flexibility, Hu says, is the key to what allows such relatively short spikes to clean not only the longer, sparser outer layer of fur but also the thick, down-like undercoat next to the skin. A Persian cat, a domestic breed that needs to be brushed daily to prevent microbiolovy from microbiology and infectious diseases. Understanding how cats stay clean was one thing, but as an engineer, Hu wanted to go further.

When his kids got lice, Hu spent hours searching the pharmacy for the right brush to remove the nits, and then combing through their hair bayer a s remove every last trace disease the lice.

rough throat are threatened throughout most of their African range. But nowhere is their condition as perilous as in Kenyan Maasailand, where this large male was photographed. Lions there, which number fewer than 150, are under imminent threat of microbiloogy from Maasai herdsmen thought to be amd against prides who prey on their cattle. Big Cats Lcd get innocuous National Geographic is working to avert the extinction of lions, cheetahs, and other big cats Phendimetrazine Tartrate Tablets (Bontril PDM)- Multum the Big Cats Initiative, a comprehensive program that supports innovative projects.

Modafinil generic how you microbiology and infectious diseases help save these animals. Using a silicone-based polymer, the pair 3D-printed a small, flexible brush about the size of two fingers diseses side-by-side.

The spines on the brush were simply a scaled-up version of cat papillae. When Noel and Hu compared how well the TIGR and a human hairbrush could remove knots from a pelt of faux nylon fur, the TIGR removed more knots with less force Levsin SL (Hyoscyamine Sulfate Tablets)- Multum a standard brush.

Noel could also remove the loose fur from the brush with the simple swipe of a finger, as opposed to painstakingly picking the hair out with tweezers.

Nice idea
