Increased Blood Pressure Variability Prior to Chronic Kidney Disease Exacerbates Renal Dysfunction in Rats.

Front Physiol

September 2016

Physiological Sciences Graduate Program, Health Sciences Center, Federal University of Espirito SantoVitoria, Brazil; Division of Nephrology, McMaster UniversityHamilton, ON, Canada.

Increased blood pressure variability (BPV), which can be experimentally induced by sinoaortic denervation (SAD), has emerged as a new marker of the prognosis of cardiovascular and renal outcomes. Considering that increased BPV can lead to organ-damage, the goal of the present study was to evaluate the effects of SAD on renal function in an experimental model of chronic kidney disease (CKD). SAD was performed in male Wistar rats 2 weeks before 5/6 nephrectomy and the animals were evaluated 4 weeks after the induction of CKD.

The initiation mechanism of IgE expression has not been fully understood. Flagellin (FGN) is an important microbial factor in the regulation of immune responses in the intestine. This study tests a hypothesis that FGN plays a crucial role in the isotype switching of IgE in B cells and the initiation of food allergy.

More Feedback Is Better than Less: Learning a Novel Upper Limb Joint Coordination Pattern with Augmented Auditory Feedback.

Front Neurosci

July 2016

Canadian Partnership for Stroke Recovery, Sunnybrook Research InstituteToronto, ON, Canada; Department of Physical Therapy and Rehabilitation Sciences Institute, University of TorontoToronto, ON, Canada.

Motor learning is a process whereby the acquisition of new skills occurs with practice, and can be influenced by the provision of feedback. An important question is what frequency of feedback facilitates motor learning. The guidance hypothesis assumes that the provision of less augmented feedback is better than more because a learner can use his/her own inherent feedback.

Measuring Neural Entrainment to Beat and Meter in Infants: Effects of Music Background.

Front Neurosci

June 2016

Department of Psychology, Neuroscience and Behaviour, McMaster UniversityHamilton, ON, Canada; McMaster Institute for Music and the Mind, McMaster UniversityHamilton, ON, Canada; Rotman Research Institute, Baycrest HospitalToronto, ON, Canada.

Caregivers often engage in musical interactions with their infants. For example, parents across cultures sing lullabies and playsongs to their infants from birth. Behavioral studies indicate that infants not only extract beat information, but also group these beats into metrical hierarchies by as early as 6 months of age.

Cyanide Toxicity to Burkholderia cenocepacia Is Modulated by Polymicrobial Communities and Environmental Factors.

Front Microbiol

May 2016

Department of Medicine, Faculty of Health Sciences, Farncombe Family Digestive Health Research Institute, McMaster UniversityHamilton, ON, Canada; Department of Biochemistry and Biomedical Sciences, Faculty of Health Sciences, McMaster UniversityHamilton, ON, Canada.

Microbes within polymicrobial communities can establish positive and negative interactions that have the potential to influence the overall behavior of the community. Pseudomonas aeruginosa and species of the Burkholderia cepacia complex (Bcc) can co-exist in the lower airways, however several studies have shown that P. aeruginosa can effectively kill the Bcc in vitro, for which hydrogen cyanide (HCN) was recently proposed to play a critical role.

Unpredicted Pitch Modulates Beta Oscillatory Power during Rhythmic Entrainment to a Tone Sequence.

Front Psychol

March 2016

Department of Psychology, Neuroscience and Behaviour, McMaster UniversityHamilton, ON, Canada; McMaster Institute for Music and the Mind, McMaster UniversityHamilton, ON, Canada; Rotman Research Institute, Baycrest HospitalToronto, ON, Canada.

Extracting temporal regularities in external stimuli in order to predict upcoming events is an essential aspect of perception. Fluctuations in induced power of beta band (15-25 Hz) oscillations in auditory cortex are involved in predictive timing during rhythmic entrainment, but whether such fluctuations are affected by prediction in the spectral (frequency/pitch) domain remains unclear. We tested whether unpredicted (i.

Dioclea violacea lectin ameliorates oxidative stress and renal dysfunction in an experimental model of acute kidney injury.

Am J Transl Res

February 2016

Physiological Sciences Graduate Program, Health Sciences Center, Federal University of Espirito SantoVitoria, ES, Brazil; Division of Nephrology, McMaster UniversityHamilton, ON, Canada.

Acute kidney injury (AKI) is characterized by rapid and potentially reversible decline in renal function; however, the current management for AKI is nonspecific and associated with limited supportive care. Considering the need for more novel therapeutic approaches, we believe that lectins from Dioclea violacea (Dvl), based on their anti-inflammatory properties, could be beneficial for the treatment of AKI induced by renal ischemia/reperfusion (IR). Dvl (1 mg/kg, i.

High expression of N-acetyltransferase 10: a novel independent prognostic marker of worse outcome in patients with hepatocellular carcinoma.

Int J Clin Exp Pathol

October 2016

Division of Hepatobiliary and Pancreatic Surgery, Department of Surgery, The First Affiliated Hospital, School of Medicine, Zhejiang UniversityHangzhou 310003, China; Key Laboratory of Combined Multi-organ Transplantation, Ministry of Public HealthHangzhou 310003, China; Key Laboratory of Organ TransplantationHangzhou 310003, China.

N-acetyltransferase 10 (NAT10) is a nucleolar protein involved in histone acetylation, telomerase activity regulation, DNA damage response and cytokinesis. The expression of NAT10 was found to be enhanced in several types of tumors, suggesting its correlation with tumor development. However, the specific role of NAT10 in hepatocellular carcinoma (HCC) is still unclear.

Synapsins are neuronal phosphoproteins crucial to regulating the processes required for normal neurotransmitter release. Synapsin II, in particular, has been implied as a candidate gene for schizophrenia. This study investigated synapsin II mRNA expression, using real-time reverse transcriptase-PCR, in coded dorsolateral prefrontal cortical samples provided by the Stanley Foundation Neuropathology Consortium.
