Protein offers way to stop microscopic parasites in their tracks

...s moving belt with traction by putting spots of an adhesive protein on it. The adhesive protein allows the host to attach to the exterior of the host cell. The resulting contact points giv...

Hirsute Or Hairless? Two Proteins May Spell The Difference

...on of E-cadherin—a membrane protein that forms the adhesive junctions between epidermal cells—is essential for allowing the cell remodeling required for bud formation. Here, the authors analyze the timing of external signals against the response of targeted cells to determine how targeted cells translate sign...

Fundamental discovery -- Bone fracture

...e ever published, which reveal the location of the adhesive or "glue" that holds together mineralized collagen fibrils (protein fibers) of bone. The glue appears to contain "springs" that uncoil when the bone is stressed, helping the bone to absorb shock. When the stress is relaxed, they coil back to their o...

Prescription pain patch abuse blamed for increase in deaths

...over the course of a few days, UF experts say. The adhesive patch is typically prescribed to treat postoperative pain or chronic pain conditions, but in some cases is being misused, often with deadly consequences. "Because the patch is a sustained release form of the drug, if one withdraws the 72 hours' wort...

Tiny shock absorbers help bacteria stick around inside the body

Like a snail through the intestinal canal

...o have a similar layer to use. To achieve this, an adhesive layer is added to the mucus-like properties, which allows the device to be stuck to the layer of mucus. The ability to be attached to a surface covered with lubricant is a great technological challenge, because most adhesives normally only work on 'c...

New sucker-footed bat discovered in Madagascar

...iscovered a new species of bat that has large flat adhesive organs, or suckers, attached to its thumbs and hind feet. This is a remarkable find because the new bat belongs to a Family of bats endemic to Madagascar--and one that was previously considered to include only one rare species. The new species, Myz...
