The awareness is growing that the proteins amyloid-beta (Aβ) and tau are rather a result of Alzheimer’s disease (AD) than its cause. Similarly, doubt reigns about the degree of causality of high plasma cholesterol/lipids (the fat connection) and of prenylation. An important conceptual addition to the current lines of thinking is advanced here. It emerged from a comparative analysis, in evolutionary retrospect, of the characteristics of the mevalonate biosynthetic pathways in insects versus in vertebrates/mammals [...]

(1) Background: Newborn affected by hypoxic-ischemic brain injury can die and the survivors suffer neurodevelopmental handicaps. Biomarkers are needed to identify the severity of hypoxic-ischemic insult in order to early determine the rescue treatment. The aim of this study was to correlate the pathophysiological process and the severity degree of the hypoxic-ischemic brain injury with relevant biomarkers in a piglet model at short and medium term. (2) Methods: Hypoxia-ischemia was induced by clamping of both carot [...]

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 design, participants completed an online survey w [...]

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 [...]

(1) Background: Sport-related concussion is a growing public health concern. Defined as a functional injury, 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 transcranial magnetic stimulation (TMS) are being applied to quantify functional changes following concussion, both from an acute perspective, but also to investigate chronic changes associated with concussion injuries. Th [...]

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

Microvascular endothelial dysfunction precedes, often by decades, the cognitive decline associated with Alzheimer's disease. Hence, preservation of a healthy cerebrovascular endothelium can be an important therapeutic target. By incorporating appropriate drug(s) into biomimetic (lipid cubic phase) nanocarriers, one obtains a multitasking combination therapeutic which targets certain cell-surface scavenger receptors, mainly class B type I (i.e., SR-BI), and crosses the blood-brain barrier. Documented similarities in [...]

Objectives: The purpose of this systematic literature review is to investigate the impact of case management on the link between HIV/AIDS patients (HIV-infected persons) and HIV treatment, and to investigate the impact of case management on their morbidity and mortality. Methods: We searched PubMed, Current Contents, Scopus, EMBASE, MEDLINE, the Effect Review Summary Database and the ACP Journal Club until May 2018. A randomized clinical trial examined the impact of case management on the association of PLHA with [...]

Hyperglycemia soon after birth is common in extremely preterm infants. Hyperglycemia is associated with severe intraventricular hemorrhage and impaired neurodevelopmental outcome in these infants. Recent data in human infants and animal models demonstrate that hyperglycemia leads to decreased white matter content, abnormal synaptogenesis, microgliosis, and functional deficits in the absence of intraventricular hemorrhage. Data suggest that oxidative stress, inflammation, and abnormal substrate metabolism are respon [...]

Purpose of review: The purpose of this review is to describe recent evidence regarding the use of Extracorporeal Membrane Oxygenation (ECMO) as salvage therapy for severe cardiac or respiratory failure in patients with traumatic brain injury (TBI) when conventional treatments have failed. The characteristics of these patients, including the risk of bleeding and developing malignant intracranial hypertension, are generally considered as relative contraindications to ECMO treatment; however, recent evidence suggests [...]
