Background: Pulmonary Arterial Hypertension (PAH) is a deadly and disabling disease for which there is no marketed drug that addresses the underlying disease mechanism and targets to cure patients. The lack of understanding of the disease mechanism represents the main challenges in developing curative therapies. We here report, for the first time, that mice lacking natriuretic peptides clearance receptor develop PAH.

Bivalve molluscs constitute a ubiquitous taxonomic group playing key functions in virtually all ecosystems, and encompassing critical commercial relevance. Along with a sessile and filter-feeding lifestyle in most cases, these characteristics make bivalves model sentinel organisms routinely used for environmental monitoring studies in aquatic habitats. The study of epigenetic mechanisms linking environmental exposure and specific physiological responses (i.

The capacity of halophiles to thrive in extreme hypersaline habitats derives partly from the tight regulation of ion homeostasis, the salt-dependent adjustment of plasma membrane fluidity, and the increased capability to manage oxidative stress. Halophilic bacteria, and archaea have been intensively studied, and substantial research has been conducted on halophilic fungi, and the green alga . By contrast, there have been very few investigations of halophiles that are phagotrophic protists, i.

Combined Action Observation and Motor Imagery Neurofeedback for Modulation of Brain Activity.

Front Hum Neurosci

January 2017

Laboratory for Brain Recovery and Function, Dalhousie UniversityHalifax, NS, Canada; Department of Psychology and Neuroscience, Dalhousie UniversityHalifax, NS, Canada; School of Physiotherapy, Dalhousie UniversityHalifax, NS, Canada; School of Health and Human Performance, Dalhousie UniversityHalifax, NS, Canada.

Motor imagery (MI) and action observation have proven to be efficacious adjuncts to traditional physiotherapy for enhancing motor recovery following stroke. Recently, researchers have used a combined approach called imagined imitation (II), where an individual watches a motor task being performed, while simultaneously imagining they are performing the movement. While neurofeedback (NFB) has been used extensively with MI to improve patients' ability to modulate sensorimotor activity and enhance motor recovery, the effectiveness of using NFB with II to modulate brain activity is unknown.

CB2 and GPR55 Receptors as Therapeutic Targets for Systemic Immune Dysregulation.

Front Pharmacol

September 2016

Department of Anesthesia, Dalhousie UniversityHalifax, NS, Canada; Department of Microbiology and Immunology, Dalhousie UniversityHalifax, NS, Canada; Department of Pharmacology, Dalhousie UniversityHalifax, NS, Canada.

The endocannabinoid system (ECS) is involved in many physiological processes and has been suggested to play a critical role in the immune response and the central nervous system (CNS). Therefore, ECS modulation has potential therapeutic effects on immune dysfunctional disorders, such as sepsis and CNS injury-induced immunodeficiency syndrome (CIDS). In sepsis, excessive release of pro- and anti-inflammatory mediators results in multi-organ dysfunction, failure, and death.

Peripheral Sensory Neurons Expressing Melanopsin Respond to Light.

Front Neural Circuits

October 2017

Department of Ophthalmology, Jules Stein Eye Institute, David Geffen School of Medicine, UCLALos Angeles, CA, USA; Brain Research Institute, UCLALos Angeles, CA, USA.

The ability of light to cause pain is paradoxical. The retina detects light but is devoid of nociceptors while the trigeminal sensory ganglia (TG) contain nociceptors but not photoreceptors. Melanopsin-expressing intrinsically photosensitive retinal ganglion cells (ipRGCs) are thought to mediate light-induced pain but recent evidence raises the possibility of an alternative light responsive pathway independent of the retina and optic nerve.

Measuring the Performance of Attention Networks with the Dalhousie Computerized Attention Battery (DalCAB): Methodology and Reliability in Healthy Adults.

Front Psychol

July 2016

Cognitive Health and Recovery Research Laboratory, Department of Psychiatry, Dalhousie UniversityHalifax, NS, Canada; Affiliated Scientist, Medical Staff, Nova Scotia Health AuthorityHalifax, NS, Canada.

Attention is an important, multifaceted cognitive domain that has been linked to three distinct, yet interacting, networks: alerting, orienting, and executive control. The measurement of attention and deficits of attention within these networks is critical to the assessment of many neurological and psychiatric conditions in both research and clinical settings. The Dalhousie Computerized Attention Battery (DalCAB) was created to assess attentional functions related to the three attention networks using a range of tasks including: simple reaction time, go/no-go, choice reaction time, dual task, flanker, item and location working memory, and visual search.

Coding Deficits in Noise-Induced Hidden Hearing Loss May Stem from Incomplete Repair of Ribbon Synapses in the Cochlea.

Front Neurosci

June 2016

Department of Physiology, Medical College of Southeast UniversityNanjing, China; School of Human Communication Disorders, Dalhousie UniversityHalifax, NS, Canada.

Recent evidence has shown that noise-induced damage to the synapse between inner hair cells (IHCs) and type I afferent auditory nerve fibers (ANFs) may occur in the absence of permanent threshold shift (PTS), and that synapses connecting IHCs with low spontaneous rate (SR) ANFs are disproportionately affected. Due to the functional importance of low-SR ANF units for temporal processing and signal coding in noisy backgrounds, deficits in cochlear coding associated with noise-induced damage may result in significant difficulties with temporal processing and hearing in noise (i.e.
