Nano particles to kill Cancer

3 March, 2019 – 4:32 am |

Using lasers and nanoparticles, scientists at Rice University have discovered a new technique to single person and destruction of diseased cells with small explosions. The scientists used a laser to create “nanoburbujas” zapping gold nanoparticles inside cells. In tests on cancer cells, they found they could adjust the laser to create or small, glowing bubbles […]

Nanodiamonds Advance Anticancer Gene Therapy

12 December, 2018 – 4:32 pm |

Gene therapy holds great promise in treating cancer and many other diseases. However, the development of a scalable system for delivering genes into cells efficiently and safely has been challenging. Now, two teams of researchers have developed a versatile nano-enabled platforms that could get therapeutic genes safely and efficiently in cancer cells. In one study, […]

Mount Sinai leads unprecedented attempt to discover rules for assembling human tissue

29 November, 2018 – 4:32 pm |

Researchers at Mount Sinai School of Medicine and two other academic institutions have received federal funding for systematic functional kidney tissue from human tissue modeling into a computer. If successful, the research that integrates several emerging technologies, including virtual modeling and nanofabrication tissues, could lead to a more predictable way for researchers to engineer tissue […]

Titanium Dioxide Nanoparticles Catalyze Brain Tumor Death

28 November, 2018 – 4:32 am |

U.S. scientists Department of Energy (DOE) Argonne National Laboratory and the University of Chicago Medical Center’s Brain Tumor Center have developed a way to target cancer cells of the brain using inorganic titanium dioxide nanoparticles bonded to antibodies. Thousands of people die from malignant brain tumors each year, and the tumors are resistant to conventional […]

Magnetic Nanoworms and Nanocrystals Deliver siRNA to Tumors

3 November, 2018 – 4:32 pm |

Small pieces of nucleic acid known as short interfering RNA, or siRNA, can disable the production of specific proteins, a property that makes them one of the most promising new classes of anticancer drugs in development. In fact, at least two siRNA-based therapies against cancer, both delivered to tumors in nanoparticles, have begun human clinical […]

To regenerate muscle, cellular garbage men must become builders

30 October, 2018 – 4:32 pm |

For scientists the European Molecular Biology Laboratory in Monterotondo, Italy, which seemed a disappointing result which proved to be an important discovery. Their findings, published online this week in the journal Proceedings of the National Academy of Sciences (PNAS), provide evidence that, when a muscle is injured, the white blood cells called macrophages play a […]

IMEC unveils promising mechanically-stacked GaAs/Ge multijunction solar cell

30 October, 2018 – 4:32 am |

In the European Photovoltaic Solar Energy Conference (Hamburg, Germany), IMEC presents a mechanical stacked GaAs / Ge multijunction solar cells. This is the technology demonstrator promising first novel IMEC to produce mechanically stacked, high-efficiency multijunction solar cells, with a view to efficiency above 40%. At the top of the stack is a contact side of […]

Obesity hinders chemotherapy treatment in children with leukemia

25 October, 2018 – 4:32 am |

Obesity is a major factor contributing to resistance to chemotherapy and increased relapse rates among children with leukemia, according to recent studies, first published online in Cancer Research, a journal of the American Association for Cancer Research. Obesity is associated with increased incidence and mortality of many cancers. Leukemia is the most common cancer in […]

IMEC presents large area solar cells with 18.4% conversion efficiency, featuring Cu-plated contacts

22 October, 2018 – 4:32 am |

In the European Photovoltaic Solar Energy Conference (Hamburg, Germany), IMEC has a large area solar conversion efficiency of 18.4%. Compared to the standard i-PERC process of the cell, solar cell includes a transmitter IMEC shallow front advanced metallization using copper coating. The results were obtained in the large area of cells (125cm2), demonstrating the industrial […]

Old red blood cells may double mortality in trauma patients

19 October, 2018 – 4:32 am |

Patients with severe trauma requiring major transfusion are twice as likely to die if they receive the red blood cells stored for one month or more, according to research published in the open access journal Critical Care BioMed Central. The highest rate of death was at the height of transfusion after six months which is […]

New discovery reveals fate of nanoparticles in human cells

12 October, 2018 – 4:32 am |

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered what happens to nanoparticles when they enter biomimetic human cells. They found that the important proteins that form the outer layer of the nanoparticles are degraded by an enzyme called cathepsin L. Scientists now have to take into account this phenomenon and […]

Multi-use device can shed light on oxygen intake

8 October, 2018 – 4:32 pm |

A fiber optic sensor developed by a team of researchers at Purdue University, which is capable of measuring oxygen consumption rates could have broad applications ranging from development of plants from roots to the evaluation of drug efficacy chemotherapy. Optrode self-reference, developed in the laboratory of Marshall Porterfield, associate professor of agricultural and biological engineering, […]

Distinct set of white blood cells found to set the pace of wound repair

26 September, 2018 – 4:32 pm |

After more than 50 experiments on mice, scientists at Johns Hopkins doctors have traced the basic measures taken by a particular set of white blood cells in determining the pace of recovery from severe lung injury. White blood cells called regulatory T cells or regulatory T cells for short, and his best-known function is to […]

Immune response to spinal cord injury may worsen damage

25 September, 2018 – 4:32 pm |

After a spinal cord injury, certain immune cells accumulate in the cerebrospinal fluid and release of high levels of antibodies. What, in any case, these antibodies is unknown. A new study by neuroscientists at the Ohio State University Medical Center may have solved the mystery. It was found that antibodies may actually get worse and […]
