  • Laser-sonic scanner aims to replace mammograms for finding breast cancer
    on June 18, 2018 at 2:26 pm

    For women over 40, mammography is a necessary yet annoying procedure to endure every year or two. The technique, while valuable for reducing breast cancer deaths, is less than ideal because it exposes patients to X-ray radiation and requires their breasts to be painfully squished between plates. The plates flatten the breast so the X-rays can more easily pass through it and produce a clear image. […]

  • Cancer: Microbubbles delivered via gas embolotherapy could cut off blood supply and deliver drugs
    on June 5, 2018 at 7:41 pm

    Embolization -- the use of various techniques to cut off the blood vessels that feed tissue growth -- has gained traction over the past decades to treat cancerous tumors, and one specific version is gas embolotherapy. During this process, the blood supply is cut off using acoustic droplet vaporization, which uses microscopic gas bubbles induced by exposure to ultrasonic waves. Researchers have discovered that these bubbles could also be used as potential drug delivery systems. […]

  • What effect does transcranial magnetic stimulation have on the brain?
    on June 5, 2018 at 2:35 pm

    Researchers have gained new insights on the question of how transcranial magnetic stimulation (TMS) effects functional interconnectivity of neurons. For visualization, they employed fluorescent dyes which provide information on the activity of neurons by light.

  • Now, you can hold a copy of your brain in the palm of your hand
    on May 30, 2018 at 3:32 pm

    Medical imaging technologies like MRI and CT scans produce high-resolution images as a series of 'slices,' making them an obvious complement to 3D printers, which also print in slices. However, the process of manually 'thresholding' medical scans to define objects to be printed is prohibitively expensive and time-consuming. A new method converts medical data into dithered bitmaps, allowing custom 3D-printed models of patient data to be printed in a fraction of the time. […]

  • Combination pack battles cancer
    on May 29, 2018 at 5:20 pm

    For efficient cancer therapy with few side effects, the active drug should selectively attain high concentration in the tumor. Scientists have introduced a new approach, in which two synergistic drug components are combined into a dimer. This dimer can be incorporated into polymeric nanotransporters at exceptionally high concentration. The components are activated when the dimer is split within the tumor. In addition, they enable use of two different imaging techniques. […]

  • Diagnosing breast cancer with an imaging pill
    on May 16, 2018 at 4:37 pm

    For women, mammograms are a sometimes uncomfortable, but necessary, annual ritual. But this procedure doesn't always provide accurate results, and it exposes women to X-rays. In a new study, scientists report that they have developed a non-invasive 'disease screening pill' that can make cancerous tumors light up when exposed to near-infrared light in mice without using radiation. […]

  • 3D images of cancer cells in the body
