First off, it was fascinating.  I am still amazed at how our bodies work and even knowing so many details I would…

  • A Potential Cartesian Eureka?

    12 Dec 2014 | 2:13 am
    For a long time I’ve been interested in Descartes’ theory of mind/body dualism. It’s a philosophy that has mostly been debunked as implausible, simply because no firm connection between the mind and body has ever been proven. Still, Rene Descartes is considered the “father of modern philosophy” because he was the first to introduce philosophy in a subjective way of thinking. Fascinating, no? Although Descartes was ultimately trying to prove the existence of God, his work has much merit. He is most famous for saying “cogito ergo sum,” which translates…

    I was standing on a mountain with a bunch of old friends the other day. We were at a mate’s property, before a huge bonfire, celebrating 2 friends’ 40th birthdays – all camping out together for the night. In my brief conversation with one of the boys, we quickly came to be talking about spirituality. “I think that’s one of the things that all of us here have in common, our sense of spirituality is all about feeling connected…. TO THE LAND!” I chimed in. Most definitely, or in Matty’s case, more the OCEAN. I make no claim to the kind of…

  • Exercise as a So Called Adult

    11 Dec 2014 | 7:27 am
    According to the Canadian Society of Exercise Physiologists (CSEP), Adults (18-64 Years) – I know, apparently we are classified as adults now – have the following guidelines: In short: - at least 150 minutes of moderate-vigorous intensity aerobic PA/week - at least 10 minutes at a time - at least 2 days of bone strengthening   How are you going about doing this?

    So things are nearing the end here at Trinity and there is just 5 days before the final round of Unifieds and the end of my first Term. I had my second Physiology quiz today and got an 80%, which makes me very happy because I was a bit worried about how I would do. This unit has been all about blood and renal and the fact that I got an 80 and 90 on each respectively shows that I’ve obviously got a pretty good handle on the material and my new studying techniques are paying off. I also haven’t gone to class this entire block, which at first may seem like a bad idea, but I say that…

Is there a more direct approach?

  • New way to lose weight - color everything blue to suppress appetite?

    The color blue suppresses appetite more than any other color. Apart from blueberries and plums, which are mostly purple, there are few naturally blue foods. The hypothesis is that in the remote past, when humans foraged for food, blue was a warning of spoilage or danger.The Buffet Blues by National Geographic: Everyone loves an all you can eat buffet, but controlling our appetites can be a bit of a struggle.

  • Lack of limb or sex differences in the cutaneous vascular responses to exogenous norepinephrine

    Greaney, J. L., Stanhewicz, A. E., Kenney, W. L., Alexander, L. M.
    15 Dec 2014 | 9:00 am
    The cutaneous circulation is used to examine vascular adrenergic function in clinical populations; however, limited studies have examined whether there are regional limb and sex differences in microvascular adrenergic responsiveness. We hypothesized that cutaneous adrenergic responsiveness would be greater in the leg compared with the arm and that these regional limb differences would be blunted in young women (protocol 1). We further hypothesized that cutaneous vasoconstriction to exogenous norepinephrine (NE) during β-adrenergic receptor antagonism would be augmented in young women…
  • Bronchoprotective effect of simulated deep inspirations in tracheal smooth muscle

    Pascoe, C. D., Donovan, G. M., Bosse, Y., Seow, C. Y., Pare, P. D.
    15 Dec 2014 | 9:00 am
    Deep inspirations (DIs) taken before an inhaled challenge with a spasmogen limit airway responsiveness in nonasthmatic subjects. This phenomenon is called bronchoprotection and is severely impaired in asthmatic subjects. The ability of DIs to prevent a decrease in forced expiratory volume in 1 s (FEV1) was initially attributed to inhibition of airway narrowing. However, DIs taken before methacholine challenge limit airway responsiveness only when a test of lung function requiring a DI is used (FEV1). Therefore, it has been suggested that prior DIs enhance the compliance of the airways or…
  • Mitochondrial cytochrome c oxidase and control of energy metabolism: measurements in suspensions of isolated mitochondria

    Wilson, D. F., Harrison, D. K., Vinogradov, A.
    15 Dec 2014 | 9:00 am
    Cytochrome c oxidase is the enzyme responsible for oxygen consumption by mitochondrial oxidative phosphorylation and coupling site 3 of oxidative phosphorylation. In this role it determines the cellular rate of ATP synthesis by oxidative phosphorylation and is the key to understanding how energy metabolism is regulated. Four electrons are required for the reduction of oxygen to water, and these are provided by the one-electron donor, cytochrome c. The rate of oxygen consumption (ATP synthesis) is dependent on the fraction of cytochrome c reduced (fred), oxygen pressure (pO2), energy state…
  • Can passive stretch inhibit motoneuron facilitation in the human plantar flexors?

    Trajano, G. S., Seitz, L. B., Nosaka, K., Blazevich, A. J.
    15 Dec 2014 | 9:00 am
    The purpose of the present study was to examine the possible inhibitory effect of passive plantar flexor muscle stretching on the motoneuron facilitatory system. Achilles tendon vibration (70 Hz) and triceps surae electrical stimulation (20 Hz) were imposed simultaneously in 11 subjects to elicit contraction through reflexive pathways in two experiments. In experiment 1, a vibration-stimulation protocol was implemented with the ankle joint plantar flexed (+10°), neutral (0°), and dorsiflexed (–10°). In experiment 2, the vibration-stimulation protocol was performed twice…
  • Mitochondrial cytochrome c oxidase: mechanism of action and role in regulating oxidative phosphorylation

    Wilson, D. F., Vinogradov, S. A.
    15 Dec 2014 | 9:00 am
    Mitochondrial oxidative phosphorylation has a central role in eukaryotic metabolism, providing the energy (ATP) required for survival. Regulation of this important pathway is, however, still not understood, largely due to limitations in the ability to measure the essential metabolites, including oxygen (pO2, oxygen pressure), ADP, and AMP. In addition, neither the mechanism of oxygen reduction by mitochondrial cytochrome c oxidase nor how its rate is controlled is understood, although this enzyme determines the rate of oxygen consumption and thereby the rate of ATP synthesis. Cytochrome c…

So-called muscle spindles and associated sensory circuits back to the spinal cord promote the establishment of novel neuronal connections after injury. This circuit-level mechanism behind the process of motor recovery was elucidated by recent research; findings may contribute to designing novel strategies for treatment after spinal cord injuries.

  • Drug may help prevent bone fractures in patients on dialysis

    11 Dec 2014 | 3:02 pm
    In patients on dialysis, cinacalcet reduced the rate of bone fracture by 16% to 29%, after accounting for patient characteristics and other factors, researchers report. Patients with kidney failure who are undergoing dialysis have an increased risk of bone fractures, and the risk of dying after a hip fracture in such a patient is double that of the general population. Unfortunately, none of the approved drugs for fracture prevention in osteoporosis in the general population are approved for use in patients on dialysis, and some are actually contraindicated.

    Pregabalin is not effective in controlling the pain associated with lumbar spinal stenosis, the most common type of chronic lower back pain in older adults, a study concludes. Pregabalin, which is marketed by Pfizer under the name Lyrica, is approved to treat chronic pain associated with shingles, spinal cord injury, fibromyalgia, and diabetic peripheral neuropathy. However, it is also commonly prescribed as an "off label" treatment for chronic low back pain syndromes like lumbar spinal stenosis.

    Researchers gain new insight into how motor neurons in the brain die during ALS. About 5 percent of ALS patients carry an altered version of a gene called C9orf72, which in ALS patients contains hundreds of repeat sequences that otherwise are not present in normal individuals. Since the gene's discovery in 2011, however, researchers have been trying to understand its normal function as well as its role in ALS, with multiple hypotheses proposed.
