Roundworms provide clues to human kidney disease
...now that defective PKD1 can cause the formation of cysts
in thekidneys, a potentially fatal condition affecting 12.5 million people worldwide. If the LOV-1 protein is indeed similar in function to PKD1, then maleroundworms could be useful for deducing the role that PKD1 plays in kidneydisease. "At first g...

were indeed collapsed where we placed the tissue. The MRI images do not enable us to distinguish between host tissue and transplant tissue, so we cant say for certain that the transplant tissue survived." (The graft tissue, which otherwise would have...
Study using human fetal tissue transplants suggests potential for spinal cord repair

that lead to limb malformations. What is now becoming more clear is the elaborate life cycle of this parasite and the mechanisms by which that may affect amphibians. The life cycle at various times includes an amphibian or fish; a bird or mammal; an...
