Nano Propellers may Be Tomorrows Drug Deliverers

...lity of targeting medicines and regularising their flow into and out of cells. Petr Krl, Assistant Professor of chemistry at UIC, and his laboratory co-workers, used classical molecular dynamics simulations to learn how tiny propellers pump liquids. They found that at the molecular level the chemist...

TB Traveler Underwent Surgery to Remove Infected Lung Tissue

...er lobe, from the blood vessels that provide blood flow and from parts of the airway that were connected. The surgeons needed a lot of precise inspection to find those blood vessels that were buried in this diseased tissue and then divide them so the lung could come out. Otherwise there could be bleedin...

According to Mozolic, the study is ongoing and will eventually include a total of 66 participants. "Behavioural and imaging data support our hypothesis that attention t...

Premature Vascular and Bone Changes Occur in COPD Patients

... COPD severity as important. The more severe the flow limitation, the higher the pulse wave velocity values, wrote Drs. Vogelmeier and Bals. Thus, COPD may induce arterial stiffness, which in turn may promote vascular remodeling, thickening of arterial walls and plaque formation. The process may start i...

Terming it a rare case, as such tumours rarely occur in the heart, Devananda said there were very few similar c...

Research Studies on Molecular Switches of Gene

...l. CREB is like a plumber who turns on the water flow in a pipe system by using a certain tool, Brindle said. What we discovered is that the CREB plumber requires different tools to turn on different genes; and that each gene determines which set of co-factor tools from CREBs toolbox it will respond to....

New Therapies may Help to Avoid Transplant in Some Heart Failure Patients

...on greater than 40 percent (measured when the pump flow was decreased). Ejection fraction is the percentage of blood pumped out of the left ventricle with each beat. Healthy hearts typically have an ejection fraction of 55 percent to 60 percent, Maybaum said. The proportion of patients showing this degree...

Sewage Flows into Hudson River in a Torrent

British Scientists Discover New Protein to Treat Epilepsy and Schizophrenia

...d: "We have found one mechanism that regulates the flow of information between cells in the brain. "It is possible that increasing the amount of SUMO attached to kainate receptors - which would reduce communication between the cells - could be a way to treat epilepsy by preventing over-excitation." Th...
