To study the role of a protein like PTB, scientists often manipulate cells to reduce the amount of that protein, and then watch to see what happens. Several years ago, a postdoctoral.. lipid가 아닌, RNA와 protein으로 vesicle만들기. These bubble-like entities—which form spontaneously when specific protein and RNA molecules are mixed in an aqueous buffer solution—hold potential as biological storage compartments. They could serve as an alternative to traditional vesicles that are made from water-insoluble organic compounds called lipids, researchers say. "Our discovery has widespread implications, from understanding basic ce.. 운동과 신진대사 유전자와의 관계 "Although short bouts of exercise have been shown to influence the gene activity in our muscles, it is the dedication to habitual exercise over a lifetime that is associated with long-term health benefits," Long-term endurance training (running or cycling) significantly changed the activity of more than 1,000 genes in both women and men compared with controls. Many of the altered genes were rela.. protein that help migrate and grow of cancer cell Research has shown faulty or mutated versions of MET to be involved in cancer cell growth and spread in a variety of cancer types; however, the precise mechanisms by which it controls these processes are unknown. MET belongs to a group of proteins called receptor tyrosine kinases (RTKs), which are key regulatory proteins involved in a variety of signaling pathways that control normal cellular pr.. Non-invasive 3D printing in living creature This new research could pave the way for minimally invasive surgical techniques for organ repair and reconstruction that could remove the need for transplantation in children with complex conditions. developed a photosensitive bio-gel that uses light treatment to "print" healthy new tissue directly into specific tissues and organs, and sustain blood supply that would allow it to thrive. The ligh.. detachable adhesive tape for Cell Tissue Last year, MIT engineers developed a double-sided adhesive that could quickly and firmly stick to wet surfaces such as biological tissues. They showed that the tape could be used to seal up rips and tears in lungs and intestines within seconds, or to affix implants and other medical devices to the surfaces of organs such as the heart. Now they have further developed their adhesive so that it can.. AFM 개선하기 Atomic force microscopy is used to scan the surfaces of materials to generate an image of their height but the technique cannot easily identify the molecular composition. Researchers have previously developed a combination of AFM and infrared spectroscopy called AFM-IR. The AFM-IR microscope uses a cantilever, which is a beam that is connected to a support at one end and a sharp tip at the other.. droplet evaporation control을 통한 cell laden hydrogel 만들기 모르는 단어 volatile: 휘발성 물질 marangoni flow? surface tension gradient에 의해서 생기는 mass transfer라고 한다. 논문을 찾아서 읽어보는 중이다. When a stationary droplet containing a solute in a volatile solvent evaporates, the flow in the droplet can assemble into complex patterns. Researchers have examined such transport in evaporating sessile droplets in solvents demonstrated flow in evaporating aqueous sessile droplets con.. 이전 1 ··· 13 14 15 16 17 18 19 다음
