We investigated whether healthy older adults who live in female-dominated old age care homes can identify the gender of male and female faces of people from different ethnicities in the same way as young adults. We hypothesized that this mainly female environment would lead by exposure to a female-gender bias. A sample of 40 participants aged 20-30 and 70-80 years identified the sex-of-face of 120 images of young and old adults, male and female faces, black and white faces, presented in a randomized sequence in a s [...]

Fibromyalgia, characterised by persistent pain, sleep disturbance, fatigue and cognitive dysfunction, is a central sensitivity syndrome that also involves abnormality in peripheral generators and in the hypothalamic pituitary adrenal axis. Heterogeneity of clinical expression of fibromyalgia with a multifactorial aetiology has made the development of effective therapeutic strategies challenging. Non-restorative sleep associated with poor sleep quality is a characteristic of fibromyalgia which is linked to symptom s [...]

Agitation is a common manifestation of acute brain injury. When not addressed, agitation can lead to slower recovery rates, including delayed admission to acute rehabilitation programs. Antipsychotics are commonly used to control agitation in acute brain injury in the ICU. However, there is no current consensus on the most "efficacious and safest strategy" for use of antipsychotics in acute TBI. Haloperidol is arguably the commonly used antipsychotic for agitation in ICU setting at present. Interestingly, there are [...]

Background: The global principles of Mindfulness-Based Stress Reduction (MBSR) have led to the creation of Mindfulness-Based Interventions (MBIs), which are interventions that retrain the mind to modify its usual stress response to increase coping and resilience. Mindfulness in Motion (MIM) is an MBI that has shown significant biologic and positive psychosocial outcomes with adult working populations, but had not previously been tested in oncology populations and their caregivers. Utilizing MIM to improve sleep qua [...]

There is a growing awareness that the proteins—amyloid-beta (Aβ) and tau—do not cause Alzheimer’s disease (AD) but are produced as a result of it. Similarly, doubt reigns over the degree of causality of high plasma cholesterol and prenylation in AD. This review proposes a fresh and important perspective, in addition to the current line of thinking. It emerges from comparative analysis, in evolutionary retrospect, of the characteristics of the mevalonate biosynthetic pathways in insects versus [...]

Background: The newborn affected by severe hypoxic-ischemic brain injury usually end up dying, and those who survive suffer neurodevelopmental handicaps. Biomarkers are required to identify the hypoxic-ischemic insult in order to determine the early rescue treatment method to be followed. The aim of the present study was to correlate relevant biomarkers to the pathophysiological process of hypoxic-ischemic brain injury at 6 h and 72 h in newborn piglets. Methods:Hypoxia-ischemia was induced in the piglets by clampi [...]

Background: Post-secondary students are at increased risk for sleep problems and poor eating behaviours that overtime may lead to negative health outcomes later in life. However, limited research has examined associations of sleep quality with eating behaviours and eating competence (e.g., being positive, flexible, and comfortable with eating and getting enough enjoyable and nutritious foods) among Canadian post-secondary students. Methods: Using a cross-sectional study design, participants completed an online surv [...]

Objective: Reversal learning requires an individual to alter their behavior when previously learned reward-based contingencies are reversed. Reversal learning is heavily influenced by cognitive flexibility, which has been shown to be enhanced with acute exercise. However, minimal work has directly evaluated the effects of acute exercise on reversal learning, which was the purpose of this experiment. Methods: A between-subject randomized controlled intervention was employed. Participants (N=60) were randomized into [...]

Background: Sport-related concussion is a growing public health concern. Defined as a injury that disturbs neurological functions, concussion is characterised by a constellation of signs and symptoms. However, clinical imaging methods do not reveal any structural damage. Recently, neurophysiological techniques such as single and paired-pulse transcranial magnetic stimulation (TMS) are being applied to quantify neurophysiological changes (specifically corticospinal and intracortical excitation and intracortical inhi [...]

Background: Many experiments have been done to demonstrate robust ischemic tolerance efficiency using mostly young and healthy animals. However, the translation of these results to usually elderly and sick patients moreover taking many various medicines has to date been disappointing. 3-Methyltin (TMT) poisoning and short-term transient cerebral ischemia cause similar damage, especially, to selectively vulnerable brain regions such as hippocampal CA1 and CA3. Methods: Using dual conditioning, we activated the full [...]
