"Many of these cysts are completely benign and have little or no risk ...

Rong Li Lab identifies new role of inflammatory protein in PKD and a possible treatment

Northwestern Memorial trial may wean kidney transplant patients off antirejection drugs

... Ill., who suffers from polycystic kidney disease (PKD), which causes cysts filled with fluid to form throughout the kidneys. Eventually, these cysts take over the healthy kidney tissue and the kidneys fail. Our family is ...

Scientists sequence genome of the N2-fixing, soil-living bacterium Azotobacter vinelandii

... to diverse sources of nutrients. For example, if no carbon source is present, A. vinelandii will undergo a differentiation process, forming cysts that are resistant to desiccation and other chemical and physical challenges. A. vinelandii belongs to the Pseudomonadaceae family. The ...

New CU-Boulder study shows diversity decreases chances of parasitic disease

... other snails and completing the life cycle. As few as 12 trematode larvae, known as cercariae, can kill or deform a single tadpole by forming cysts in its developing limbs, causing missing limbs, extra limbs and other severe malformations, Johnson said. A 2007 CU-Boulder study led by Johnson ...

Gaining a better understanding of kidney diseases

... to be associated with elevated levels of this transcription factor. Shortly after activation of the c-Myc gene the animals started developing cysts that led to organ failure. Pathologists also discovered renal cell carcinomas in some of the mice. As a reaction to the overexpression of another ...

In computer models and observations, researchers see potential for significant 'red tide' season

... have adequate staff for the significant monitoring efforts that might be required to protect public health and the shellfish industry. Seeds or cysts of A. fundyense naturally germinate and turn into swimming cells that rise from the seafloor around April 1 of each year. By the end of April, cells ...

Soybean varieties viable in southern Indiana, resistant to root-knot nematode

... because it stays on the outside. These pinhead-sized nematodes are white, then yellow, and finally become brown as they mature. The nematode-induced cysts are much smaller than the so-called "nodules," which are structures induced by the beneficial bacterium rhizobium. Rhizobium association aids the ...

Nutrient pollution drives frog deformities by ramping up infections, says CU-Boulder study

... growth, increasing snail populations and the number of infectious parasites released by snails into ponds and lakes. The parasites subsequently form cysts in the developing limbs of tadpoles causing missing limbs, extra limbs and other severe malformations, Johnson said. "This is the first study to ...

Scientists discover that widely available drug also helps fight kidney disease

... that increase virulence is the cause of the infection. Humans can become infected by the parasite by accidentally consuming or inhaling the cysts from infected cat feces, by eating meat from an infected animal - especially pork, lamb or venison - or by drinking contaminated water. Cats are ...

Gene therapy works in mice to prevent blindness that strikes boys

... secrete a protein called retinoschisin, or RS1, which acts like glue to connect the layers of the retina. Without it, the layers separate and tiny cysts form, devastating the vision and often leading to blindness in about 1 of every 5,000 boys. UF researchers injected a healthy version of the human ...
