Aim: To evaluate development of brain injury after hind limbs ischemia/reperfusion (LI/R) in rats, and the effect of MK801 on the brain injury following LI/R.
Methods: The limbs ischemia/reperfusion model was established in rats. The MDA contents were evaluated in each group, apoptotic cells were detected with TUNEL, the expression of apoptosis-associated protein, such as bcl-2, cytoC and caspase-3 were determined with immunohistochemistry and Western-blot.
Results: The contents of MDA in brain tissue increased significantly following LI/R. The expression of bcl-2, cytoC, Caspase-3 was increased than those in the control group (P < 0.01) following LI/R significantly. The expression of Caspase-3 was increased 24 h after the onset of reperfusion. The expression of Caspase-3, bcl-2 gene was quite obvious in the midbrain red nucleus region. MK801 inhibited the expression of bcl-2, cytoC, Caspase-3 obviously.
Conclusion: The excessive apoptosis and apoptosis-associated factors could play an important role in the brain injury following LI/R in rat, MK801 might decrease the production of free radical and the excite toxicity of glutamate, inhibit the expression of apoptosis associated protein and reduce the occurrence of apoptosis.

Atrial Fibrillation-Related Bradycardia and/or Bradycardia-Related Atrial Fibrillation: When and How to Intervene.
Curr Vasc Pharmacol

Department of Cardiology, Athens University School of Medicine, Athens, Greece.
Introduction/objective: Atrial fibrillation (AF) could present with slow ventricular-response; bradycardia could facilitate the emergence of AF. The conviction that one "does not succumb" from bradycardia as an escape rhythm will emerge unless one sustains a fatal injury following syncope is in stark difference with ventricular tachyarrhythmia (VA), which may promptly cause cardiac arrest. However, this is not always the case, as a life-threatening situation may emerge during the bradycardic episode, i.

Purposeof Review: In this article, we explore the current literature on traumatic brain injury (TBI) in survivors of intimate partner violence (IPV) and evaluate the barriers to studying this vulnerable population.
Recent Findings: Research on TBI and IPV is limited by multiple factors including mistrust of the healthcare system by survivors, lack of awareness by community advocates, and insufficient funding by public entities. As such, most investigations are small population, retrospective, and qualitative.

Division of Pediatric Critical Care Medicine, Icahn School of Medicine at Mount Sinai, New York, New York, USA.
Objectives: Pediatric status epilepticus (SE) carries a high risk of morbidity and mortality and can result in neurologic injury. Establishing seizure activity on conventional EEG (cEEG) is essential but can delay treatment of seizures due to technician limitations. Rapid response EEG (rrEEG) device Ceribell and its Brain Stethoscope function can be used and interpreted rapidly by bedside providers with minimal training.

Background: Obesity and metabolic syndrome are major public health concerns linked to cognitive decline with aging. Prior work from our lab has demonstrated that short-term high fat diet (HFD) rapidly impairs memory function via a neuroinflammatory mechanism. However, the degree to which these rapid inflammatory changes are unique to the brain is unknown.
