  • Mere expectation of treatment can improve brain activity in Parkinson's patients

    Nervous System News -- ScienceDaily
    25 Nov 2014 | 11:08 am
    Learning-related brain activity in Parkinson's patients improves as much in response to a placebo treatment as to real medication, according to a new study. "The findings highlight the power of expectations to drive changes in the brain," said a co-author of the study. "The research highlights important links between psychology and medicine."

    In comparison with open surgery, while minimally invasive surgery for cervical or lumbar discectomy may speed up recovery and reduce post-operative pain, it does not improve long-term function or reduce long-term extremity pain.
  • Pain and itch in a dish: Scientists convert human skin cells into sensory neurons

    Nervous System News -- ScienceDaily
    25 Nov 2014 | 7:43 am
    Scientists have found a simple method to convert human skin cells into the specialized neurons that detect pain, itch, touch and other bodily sensations. These neurons are also affected by spinal cord injury and involved in Friedreich's ataxia, a devastating and currently incurable neurodegenerative disease that largely strikes children.
  • Effect of vitamin C on hyperoxia-induced vasoconstriction in exercising skeletal muscle

    Journal of Applied Physiology current issue
    Ranadive, S. M., Joyner, M. J., Walker, B. G., Taylor, J. L., Casey, D. P.
    15 Nov 2014 | 9:00 am
    Hyperoxia can cause substantial reductions in peripheral and coronary blood flow at rest and during exercise, which may be caused by reactive oxygen species (ROS) generated during hyperoxia. The aim of this study was to investigate the role of ROS in hyperoxia-induced reductions in skeletal muscle blood flow during forearm exercise. We hypothesized that infusion of vitamin C would abolish the effects of hyperoxia on the forearm blood flow (FBF) responses to exercise. Twelve young healthy adults performed rhythmic forearm handgrip exercise (10% of maximum voluntary contraction for 5 min)…

  • Link between DNA transcription, disease-causing expansions

    25 Nov 2014 | 10:19 am
    Researchers in human genetics have known that long nucleotide repeats in DNA lead to instability of the genome and ultimately to human hereditary diseases such Freidreich's ataxia and Huntington's disease. Scientists have believed that the lengthening of those repeats occur during DNA replication when cells divide or when the cellular DNA repair machinery gets activated. Recently, however, it became apparent that yet another process called transcription, which is copying the information from DNA into RNA, could also been involved.

  • In Him (Christ) Lie Hidden All The Treasures of Wisdom and Knowledge

      In Him (Christ)lie hidden all the treasures of wisdom and knowledge; God’s calling, will you answer? One of the driving forces behind writing the book, “Facts Your Way to Heaven – From religion to relationship,” was to steer people away from man and his religious philosophy and limited insight of life as we know it, considering we are the created, not the Creator. In addition, yours truly was motivated in hopes that man would begin to see a clear distinction of what is missing in his life today, and in his current belief system, as he finds himself chasing after…

    Gut microbes and the brain: paradigm shift in neuroscience. http://www.ncbi.nlm.nih.gov/pubmed/25392516 Abstract The discovery of the size and complexity of the human microbiome has resulted in an ongoing reevaluation of many concepts of health and disease, including diseases affecting the CNS. A growing body of preclinical literature has demonstrated bidirectional signaling between the brain and the gut microbiome, involving multiple neurocrine and endocrine signaling mechanisms. While psychological and physical stressors can affect the composition and metabolic activity of the gut…
  • Discovering one's own transgender identity

    Through the shadows… Ever since I was young, I knew that there was a discrepancy between my sex and my gender identity. it would come out in small ways when I was young, in that I would like to wear women’s clothing in private as well as had a more emotional connection with female groups than with male groups. When I was young I heard the phrase, “lesbian stuck in a man’s body” and it could not have been more true to my feelings. Sometime between age 11 and 15 I discovered that sex change operations were a reality. I remember a great relief washed over me,…

    Fall vineyard colors. Something about them makes you want to grab a bottle of red, put another log on the fire, grab a blanket and someone to get under it with…. No? Maybe just us. Yellows, oranges and browns are the tell-tale signal of fall. Each year, the bright, green reminiscent of spring and summer in leaves fades away, giving way to the cozy fall colors that make you want to break out the scarves and gives you a sudden urge for pumpkin spiced lattes in the red Starbucks Christmas cups.

  • Revisiting the Sternocleidomastoids: Accessory Muscles of Respiration

    Amiya Sarkar
    6 Feb 2014 | 1:20 pm
    We know that sternocleidomastoids (strap muscles of the neck), scalene muscles and alae nasi are considered accessory muscles of breathing, although some controversy exists. If you saw an asthmatic individual in his desperate attempts at breathing or an agitated person or a person exercising vigorously, you could watch these muscles in action. However, that wasn't exactly what I had in mind while I was doing this experiment. I was really thrilled to chance upon it. Kind of a serendipitous discovery in its own right. You too can figure this out easily. The placement of the surface…
  • Making a Human Interface Device Using SpikerBox

    6 Feb 2014 | 11:56 am
    Q said to Bond: It's activated by nerve impulses from the wrist muscles. This dialog from the 1979 James Bond movie, Moonraker, seems to fit into place when we talk about interfacing biosignals (surface EMG, in this case) with an actuator. [Watch a clip from the movie below] In order to achieve this human-machine interface using our good not-so-old spikerbox, we need to estimate the output signal amplitude coming from the extensors of the wrist (around 5 mV), amplify the signal by some 300 times by cascading two LM 386 IC (or any opamp taking care that the device doesn't go into…

    15 Nov 2014 | 9:00 am
    Our investigation was designed to determine whether the time of day affects the carbon dioxide reserve and chemoreflex sensitivity during non-rapid eye movement (NREM) sleep. Ten healthy men with obstructive sleep apnea completed a constant routine protocol that consisted of sleep sessions in the evening (10 PM to 1 AM), morning (6 AM to 9 AM), and afternoon (2 PM to 5 PM). Between sleep sessions, the participants were awake. During each sleep session, core body temperature, baseline levels of carbon dioxide (PetCO2) and minute ventilation, as well as the PetCO2 that demarcated the apneic…
  • Morning pentraxin3 levels reflect obstructive sleep apnea-related acute inflammation

    This study investigated morning levels of pentraxin3 (PTX3) as a sensitive biomarker for acute inflammation in patients with obstructive sleep apnea (OSA). A total of 61 consecutive patients with OSA were divided into two groups: non-to-mild (n = 20) and moderate-to-severe (n = 41) OSA based on their apnea-hypopnea index (AHI) score. Those patients with moderate-to-severe OSA were further divided into continuous positive airway pressure (CPAP) treated (n = 21) and non-CPAP-treated (n = 20) groups. Morning and evening serum PTX3 and high-sensitivity (hs) C-reactive protein (CRP) levels were…

  • Recovery of the pulmonary chemoreflex and functional role of bronchopulmonary C-fibers following chronic cervical spinal cord injury

    Lee, K.-Z., Chang, Y.-S.
    15 Nov 2014 | 9:00 am
    Persistent impairment of pulmonary defense reflexes is a critical factor contributing to pulmonary complications in patients with spinal cord injuries. The pulmonary chemoreflex evoked by activation of bronchopulmonary C-fibers has been reported to be abolished in animals with acute cervical hemisection (C2Hx). The present study examined whether the pulmonary chemoreflex can recover during the chronic injury phase and investigated the role of bronchopulmonary C-fibers on the altered breathing pattern after C2Hx. In the first protocol, bronchopulmonary C-fibers were excited by intrajugular…
