  • Having a meal activates the functioning of human brown fat
    on June 20, 2018 at 1:47 pm

    The importance of the human brown adipose tissue (BAT) has become clearer during the past ten years. Using positron emission tomography, PET, it was shown that adult humans have functional BAT. Coldness is an effective activator of the BAT metabolic function but, in rodents, eating has the same effect. Now, researchers have shown that having a meal increases oxygen consumption in human BAT as much as coldness. […]

  • 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. […]

  • 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. Using this technique, they showed in an animal model that TMS predisposes neuronal connections in the visual cortex of the brain for processes of reorganization. […]

  • 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. […]

    An international team has discovered how to exploit defects in nanoscale and microscale diamonds and potentially enhance the sensitivity of magnetic resonance imaging and nuclear magnetic resonance systems while eliminating the need for their costly and bulky superconducting magnets. […]

  • Gadolinium deposition in the brain not dose dependent
    on May 11, 2018 at 2:24 pm

    Investigators have determined that in children receiving gadolinium as a contrast agent to enhance MRI examinations, signal changes attributed solely to deposition of this material in the brain are not dependent on the amount of gadolinium administered but rather these changes are seen in association with other factors such as the presence of brain tumors and treatment using brain irradiation. […]

    on May 3, 2018 at 6:29 pm

    After eight years of failed treatment for persistent atrial fibrillation (AF), a New Jersey patient became the first patient in the United States to undergo cardiac ablation -- a procedure in which an electrophysiologist will scar or destroy tissue in the heart that's allowing incorrect electrical signals to cause an abnormal heart rhythm -- using an intraoperative imaging and mapping system recently cleared by the Food and Drug Administration (FDA). […]

  • Water dynamics indicate tumor status
    on April 18, 2018 at 6:14 pm

    How aggressive is a tumor? To measure the tumor status without taking tissue samples, researchers have developed a method based on magnetic resonance imaging (MRI) of whole body parts. The technique measures proton nuclear resonance dispersion profiles at low magnetic fields, which reveals the water exchange rate of the tumor cells. Thus, tumor development can be monitored rapidly and noninvasively. […]

  • Detailed images of tumor vasculature
    on April 18, 2018 at 3:16 pm

    Thanks to a new method of analyzing ultrasound images, conventional scanners can be used for generating high-res images of blood vessels in tumors. This approach makes it easier to distinguish between different types of tumors, and it facilitates the tracking of the progress and success of chemotherapy. […]
