Introducing the First Vehicle Powered by Evaporation More Science: Baby Chicks'Mental Number Line Looks like Ours
#Plastic parts for internal combustion engines Efforts to produce lighter vehicles necessarily include engine parts, such as the cylinder casing,
Fraunhofer ICT It self-evident that cars must become lighter in order to reduce fuel consumption. For most car designers this principally means body parts
but the powertrain system, which includes the engine, also accounts for a large proportion of the vehicle weight.
Until now, carmakers have relied on aluminum to reduce the weight of engine components such as the cylinder block.
In the future, car manufacturers will be able to achieve further weight savings by designing cylinder blocks in which certain parts are made of fiber-reinforced plastics.
An experimental engine developed by the Fraunhofer project group for new drive systems (NAS), which forms part of the Fraunhofer Institute for Chemical Technology ICT, in collaboration with SBHPP, the high-performance plastics business unit of Sumitomo Bakelite Co. Ltd.,

have been refining cell-surface sensors known as chimeric antigen receptors, or CARS. Once inserted into T cells,
CARS prompt these cells to home in on particular proteins found primarily in tumors, where they launch a series of cancer-killing immune responses.
Dangers of CAR T cell Therapy CAR-equipped T cells have proven to be remarkably successful in the treatment of various forms of chemotherapy-resistant leukemia
But CAR T cell therapy can cause side effects so serious that they may require monitoring in an Intensive care unit several patients have died after receiving CAR T cells
while theye in the body. ome scientists have grappled with these problems by developing uicide switchesthat kill off CAR T cells
creating a new type of CAR T cell that is ffby default. Like CONVENTIONAL CAR T cells, these newly developed T cells will navigate toward

This controller drug forms a chemical bridge between components inside the CAR T cells flipping the cells into an active, nstatus.
and selectively eliminated by the Lim group new CAR T cells, but only after the controller drug had been administered.
and colleagues does more than merely switch CAR T cells between nand ffstates. It can also act like a rheostat:
These combined control capabilities could be employed to manage the various side effects of CAR T therapy.
For CAR T cell treatments, T cells are removed from a patient blood, genetically engineered to carry CARS that target the patient tumor,
then reinserted into the bloodstream to exert their effects. Once inside the body, in addition to attacking tumors directly, CAR T cells, like all T cells, release signaling molecules called cytokines, some
of which recruit additional T cells to fight the tumor. Sometimes normal cells express small amounts of a cancer-associated protein targeted by a CAR T cell.
Because CAR T cells placed in the bloodstream pass immediately through the heart and lungs, these tissues can be damaged before the CAR T cells reach their intended target elsewhere in the body.
The control offered by the Lim laboratory new cells would allow physicians to leave CAR T cells inactivated until the heart
and lungs are less vulnerable to these irst passside effects. Even when CAR T cells attack only their correct target cancer cells,
side effects can still occur. In tumor lysis syndrome, the body is overwhelmed by toxic substances released when many tumor cells die in rapid succession.
Another side effect, known as a ytokine storm is a life-threatening vicious cycle in which released cytokines summon numerous T cells to the tumor,
but he believes that the research provides the foundation for practical remote control of CAR T cells on the near horizon.
In addition to drug control of CAR T nswitches, members of his laboratory are exploring other techniques to accomplish this goal,
such as controlling CAR T cell activation with light. While successful against blood cancers such as leukemia, CAR T cells have shown so far less efficacy against solid tumors that effect the colon, breast, prostrate, brain and other tissues.
The remote control strategy developed by Lim group may permit researchers to develop more powerful versions of CAR T cells that could attack these solid tumors,
while still keeping side effects in check. Members of the Lim laboratory are also working to reduce side effects by introducing multiple CARS into T cells
so that the cells will respond to multiple characteristics that are distinctive to an individual patient tumor,
and the Howard hughes medical institute. hat we can engineer CAR T cells to have slightly different, quite powerful effects even if for a subset of patients or for certain types of cancer is really remarkable,
these pseudo-platelets can circulate for up to 30 hours as compared to approximately six hours for the nanoscale vehicles without the coating.
