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 [...]

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 c [...]

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 rescue therapy for refractory 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 sugges [...]

Background: Parkinson's disease (PD) is the second most common neurodegenerative disease and is a synucleinopathy due to the critical role of α-synuclein (α-Syn) in its pathology. α-Syn is able to translocate from the cytoplasm to the nucleus and cause DNA damage. Methods: SH-SY5Y cells were stably transfected with plasmids containing wild type (WT) α-Syn and A53T mutant α-Syn as fusion proteins with EGFP and an EGFP only control vector. The cells were differentiated using retinoi [...]

Aneurysmal subarachnoid hemorrhage (aSAH) causes serious brain injury, and its mechanisms have not been completely unraveled so far. The causative factors for the brain injury initiated by an aneurysm rupture, which is referred to as the early brain injury (EBI), include elevated intracranial pressure, cerebral hypoperfusion, and blood contents that are directly exposed to the brain surface. At Day 4–14 post aSAH, delayed cerebral ischemia (DCI) often develops, which may worsen the neurological outcomes critically. [...]

Background: Several recommendations on optimum sleep duration have been published for adolescents to secure a healthy life. This study aimed to compare the sleep duration of middle and high school pupils in Japan with the recommended values and determined the factors associated with the duration of sleep among them. Methods: A total of 1766 completed questionnaires were obtained from grades 7 to 12 pupils in Japan. The questionnaire addressed the following points: sleeping, eating, defecation, physical activity, sc [...]
