2 Americans and a German win 2013 Nobel medicine prize Updated 6:35 a.m. ET STOCKHOLM Us citizens James Rothman and Randy Schekman and German-born researcher Thomas Suedhof gained the 2013 Nobel Prize in medicine on Monday for discoveries on how hormones, enzymes and various other key chemicals are transported within cells. The Nobel committee stated their analysis on vesicle visitors – the transport system of our cells – helped scientists understand how cargo is delivered to the right place at the right time inside cells. Disturbances to the machine can contribute to diabetes and neurological and immunological disorders, the committee said.Samples attained at an altitude higher than the Everest foundation camp were attained from the proper femoral artery, determined by digital palpation. Intraarterial placement of the needle was verified by pulsatile filling of a heparinized 2-ml oiled glass syringe . Syringes were immediately sealed with an airtight cap and placed in a plastic handbag, which was placed in an ice-water slurry in a insulated vacuum flask. The flask was quickly transported to a laboratory at Camp 2 in the Western Cwm; the length of time for this transfer to become completed was documented. Barometric pressure was measured at the altitude at which the blood samples were taken, by using a handheld digital barometer .
