    An Ebola whole virus vaccine, constructed using a novel experimental platform, has been shown to effectively protect monkeys exposed to the often fatal virus. It differs from other Ebola vaccines because as an inactivated whole virus vaccine, it primes the host immune system with the full complement of Ebola viral proteins and genes, potentially conferring greater protection.

  • Long-standing mystery in membrane traffic solved

    27 Mar 2015 | 8:18 am
    In 2013, James E. Rothman, Randy W. Schekman, and Thomas C. Südhof won the Nobel Prize in Physiology or Medicine for their discoveries of molecular machineries for vesicle trafficking, a major transport system in cells for maintaining cellular processes. SNARE proteins are known as the minimal machinery for membrane fusion. Scientists now report that NSF/?-SNAP disassemble a single SNARE complex using various single-molecule biophysical methods that allow them to monitor and manipulate individual protein complexes.

  • Calcium channels play a role in neuronal homeostasis, elimination of toxic buildup of proteins

    26 Mar 2015 | 12:16 pm
    Mutations of human homologs (genes that carry out similar functions) of cacophony and its partner straightjacket cause defects in autophagy in neurons, researchers have discovered. Autophagy is the body's first-line of defense against the buildup up of toxic substances, degrading old organelles and proteins to provide new substrates and building blocks. In this way, autophagy prevents the buildup of "garbage" that can result in destruction of neurons and cause neurologic diseases.

  • Fate vs. Free Will

    Colleen Walser
    19 Mar 2015 | 3:40 pm
      I’ve heard many a discussion over the concept of free will and how much of it we really have. Some advocate the idea that free will is an utter illusion. A lot of people say we don’t have free will and just as many will argue that we have total free will. But again, they are only acknowledging pieces – fragments – of the full concept. In reality, I believe it’s both…it just depends on what angle you’re choosing to look at it from. fave-vs-free-will Personally, I believe that free will is far more complex than we think it is. We have a tendency to think about a lot of…

  • How to Awaken Your Intuition

    19 Mar 2015 | 3:25 pm
    The intellect has little to do on the road to discovery. There comes a leap in consciousness, call it intuition or what you will, and the solution comes to you and you don’t know why or how. ~Albert Einstein We’ve all heard it so many times – ‘Just listen to your inner voice’, or ‘Just follow your intuition’, haven’t we? But in a world, where rational thinking is considered to be the ‘normal’ thing to do, the process of learning how to follow your intuition may be a confusing and even painful one. With so many decisions to make on a daily basis, it’s easy to become…
  • What is Reiki

    Colleen Walser
    19 Mar 2015 | 3:07 pm
    Reiki is one of the most ancient healing methods known to mankind. It is a method of relaxation and stress reduction that also promotes healing. The technique was discovered in Japan and is based on the idea that all living things have a special energy flowing through them called life energy. When your life energy is high, you will feel strong and confident, be more relaxed and centered and less likely to become sick. When your life energy is low or depleted, you will be more easily affected by stress and experience physical, mental and emotional exhaustion. Reiki (pronounced Ray-key) is a…

  • Most cancers caused by "bad luck" in cell division and "poor repair" of the defect

    5 Mar 2015 | 4:30 am
    Researchers at Johns Hopkins University studied 31 different cancers. Of those, just 9 were found to be linked to bad genetics or unhealthy lifestyle choices. However, researchers excluded two of the most common cancers from their study, breast cancer and prostate cancer (published in the journal Science). The most common cause of the production of most cancerous cells occurs when one chemical letter in DNA is incorrectly swapped for another during stem cell division. Scientists found that cancer rates were higher in parts of the body where cells are quickest to regenerate, thereby creating…

  • Pharyngeal mucosal wall folds in subjects with obstructive sleep apnea

    Kairaitis, K., Foster, S., Amatoury, J., Verma, M., Wheatley, J. R., Amis, T. C.
    15 Mar 2015 | 9:30 am
    Mechanical processes underlying pharyngeal closure have not been examined. We hypothesized that the pharyngeal mucosal surface would fold during closure, and lowering the upper airway lining liquid surface tension would unfold areas of mucosal apposition, i.e., folds. We compared baseline pharyngeal fold numbers and response to reduction in upper airway liquid surface tension in healthy and obstructive sleep apnea (OSA) subjects. Awake, gated magnetic resonance pharyngeal airway images of 10 healthy and 11 OSA subjects were acquired before and after exogenous surfactant administration…
  • The gain of smooth muscle's contractile capacity induced by tone on in vivo airway responsiveness in mice

    Lee-Gosselin, A., Gendron, D., Blanchet, M.-R., Marsolais, D., Bosse, Y.
    15 Mar 2015 | 9:30 am
    Airway hyperresponsiveness to a spasmogenic challenge such as methacholine, and an increased baseline tone measured by the reversibility of airway obstruction with a bronchodilator, are two common features of asthma. However, whether the increased tone influences the degree of airway responsiveness to a spasmogen is unclear. Herein, we hypothesized that increased tone augments airway responsiveness in vivo by increasing the contractile capacity of airway smooth muscle (ASM). Anesthetized, tracheotomized, paralyzed, and mechanically ventilated mice were either exposed (experimental group) or…
  • Extracellular Ca2+-induced force restoration in K+-depressed skeletal muscle of the mouse involves an elevation of [K+]i: implications for fatigue

    Cairns, S. P., Leader, J. P., Loiselle, D. S., Higgins, A., Lin, W., Renaud, J.-M.
    15 Mar 2015 | 9:30 am
    We examined whether a Ca2+-K interaction was a potential mechanism operating during fatigue with repeated tetani in isolated mouse muscles. Raising the extracellular Ca2+ concentration ([Ca2+]o) from 1.3 to 10 mM in K-depressed slow-twitch soleus and/or fast-twitch extensor digitorum longus muscles caused the following: 1) increase of intracellular K activity by 20–60 mM (raised intracellular K content, unchanged intracellular fluid volume), so that the K-equilibrium potential increased by ~10 mV and resting membrane potential repolarized by 5–10 mV; 2) large restoration of action…
  • Modeling the impairment of airway smooth muscle force by stretch

    Bates, J. H. T.
    15 Mar 2015 | 9:30 am
    Imposed length changes of only a small percent produce transient reductions in active force in strips of airway smooth muscle (ASM) due to the temporary detachment of bound cross-bridges caused by the relative motion of the actin and myosin fibers. More dramatic and sustained reductions in active force occur following large changes in length. The Huxley two-state model of skeletal muscle originally proposed in 1957 and later adapted to include a four-state description of cross-bridge kinetics has been widely used to model the former phenomenon, but is unable to account for the latter unless…
  • Onset of asphyxial state in nonrespiring interval between cord clamping and ventilation increases hemodynamic lability of birth transition in preterm lambs

    Smolich, J. J., Kenna, K. R., Cheung, M. M.
    15 Mar 2015 | 9:30 am
    Experimentally, a typical ~2-min cord clamp-to-ventilation interval in preterm lambs is accompanied by increased hemodynamic lability of the birth transition. However, whether this lability is related to development of asphyxia after cord clamping, or can be avoided with a shorter clamp-to-ventilation interval, is unknown. To address these questions, anesthetized preterm fetal lambs (gestation 127 ± 2 days) were instrumented with ductus arteriosus and left pulmonary artery flow probes to obtain right ventricular (RV) output, brachiocephalic trunk and aortic isthmus flow probes to…

    27 Mar 2015 | 6:09 am
    Colorectal cancer is the third most common form of cancer globally and the second most common cause of cancer deaths. The chance of a cure is high if the cancer is detected early enough, but early detection is not a given. Researchers have identified bio-markers that can be incorporated in a new diagnostic test. This should make it possible to detect colorectal cancer in an early stage using a simple blood test, they say.
