Neuroplasticity and regeneration after spinal cord injury.

Spinal cord injury (SCI) is a debilitating condition with significant personal, societal, and economic burden. The highest proportion of traumatic injuries occur at the cervical level, which results in severe sensorimotor and autonomic deficits. Following the initial physical damage associated with traumatic injuries, secondary pro-inflammatory, excitotoxic, and ischemic cascades are initiated further contributing to neuronal and glial cell death.

Endothelial ACKR1 is induced by neutrophil contact and down-regulated by secretion in extracellular vesicles.

Atypical chemokine receptor-1 (ACKR1), previously known as the Duffy antigen receptor for chemokines, is a widely conserved cell surface protein that is expressed on erythrocytes and the endothelium of post-capillary venules. In addition to being the receptor for the parasite causing malaria, ACKR1 has been postulated to regulate innate immunity by displaying and trafficking chemokines. Intriguingly, a common mutation in its promoter leads to loss of the erythrocyte protein but leaves endothelial expression unaffected.

A long wait: barriers to discharge for long length of stay patients.

Introduction: Reducing long length of stay (LLOS, or inpatient stays lasting over 30 days) is an important way for hospitals to improve cost efficiency, bed availability and health outcomes. Discharge delays can cost hundreds to thousands of dollars per patient, and LLOS represents a burden on bed availability for other potential patients. However, most research studies investigating discharge barriers are not LLOS-specific.

Spike history neural response model.

There is a potential for improved efficacy of neural stimulation if stimulation levels can be modified dynamically based on the responses of neural tissue in real time. A neural model is developed that describes the response of neurons to electrical stimulation and that is suitable for feedback control neuroprosthetic stimulation. Experimental data from NZ white rabbit retinae is used with a data-driven technique to model neural dynamics.

[Extracorporeal methods of hematological correction in patients with acute liver insufficiency after cardiac surgery].

Background & Aims: Acute liver failure (ALF) usually develops in multiple organ dysfunction syndrome (MODS) and carries a high mortality risk in patients after cardiac surgery. Artificial liver support devices aim to remove albumin-bound and water-soluble toxins arising as a result of liver failure. The currently most used devices combine haemodialysis with albumin dialysis (MARS) or plasma separation and adsorption (Prometheus).
