Department of Physiology and Pathophysiology, Rady Faculty of Health Sciences, Max Rady College of Medicine, University of Manitoba, Winnipeg R3E0J9, Canada.

Article Synopsis
  • Oxylipins, which are lipid mediators derived from fatty acids, play crucial roles in respiratory health, but their profiles in lung structural cells are not fully understood.
  • The study measured 162 oxylipins in airway smooth muscle, lung fibroblasts, and epithelial cells, both at baseline and after exposure to various stimuli.
  • Results showed that airway smooth muscle and lung fibroblasts had similar oxylipin profiles dominated by CYP450 metabolites, while epithelial cells had a unique profile rich in COX-derived oxylipins, with distinct changes noted upon stimulation that could impact respiratory function.

Introduction: Saskatoon berries are grown in Canada and some northwestern states in the United States, and are notable for containing abundant antioxidant polyphenols, vitamins, metal elements, and fiber. To increase consumer interest in and accessibility to Saskatoon berries, some producers have begun to develop processes for refining Saskatoon berries into a powder with an extended shelf life that can be incorporated into a variety of value-added food products. To assess the desirability of this approach, this study sought to determine how the sensory attributes, consumer acceptability, and volatile and non-volatile composition of a plain, Greek-style frozen yogurt (PY) changed when fortified with 16% Saskatoon berry powder (SBP).

Home enteral nutrition (HEN) is a vital feeding practice for those who have chronic disorders that prevent them from eating normally. Although short-term feeding is predominantly done via nasogastric (NG) tubes and long-term feeding is done via percutaneous endoscopic gastrostomy (PEG) tube, we present a case that demonstrates that the long-term use of NG tubes may be possible. Our case involves an adult woman who has been fed via an NG tube for >3 years with no complications.

Background Patients hospitalized with acute stroke are at risk of developing acute kidney injury (AKI), and when both conditions occur together, patient outcomes are often worse. The relationship between stroke type, patient characteristics, and the development of AKI is not fully understood, particularly in tertiary care settings in Pakistan, where healthcare resources and patient characteristics may differ from Western populations. Objective To determine the frequency of AKI and identify associated risk factors, including stroke type, severity, and comorbidities, in patients presenting with acute stroke at a tertiary care center in Pakistan, the Hayatabad Medical Complex, Peshawar.

Background: Mechanical stress and pathological signaling trigger the activation of fibroblasts to myofibroblasts, which impacts extracellular matrix composition, disrupts normal wound healing, and can generate deleterious fibrosis. Myocardial fibrosis independently promotes cardiac arrhythmias, sudden cardiac arrest, and contributes to the severity of heart failure. Fibrosis can also alter cell-to-cell communication and increase myocardial stiffness which eventually may lead to lusitropic and inotropic cardiac dysfunction.

Division of Neurodegenerative Disorders, St. Boniface Hospital Albrechtsen Research Centre, University of Manitoba, Winnipeg, Canada; Department of Pharmacology and Therapeutics, Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, Canada. Electronic address:

Objective: Antagonism of the muscarinic acetylcholine type 1 receptor (MR) promotes sensory axon repair and is protective in peripheral neuropathy, however, the mechanism remains elusive. We investigated the role of the heat-sensing transient receptor potential melastatin-3 (TRPM3) cation channel in MR antagonism-mediated nerve regeneration and explored the potential of TRPM3 activation to facilitate axonal plasticity.

Methods: Dorsal root ganglion (DRG) neurons from adult control or diabetic rats were cultured and treated with TRPM3 agonists (CIM0216, pregnenolone sulfate) and MR antagonists pirenzepine (PZ) or muscarinic toxin 7 (MT7).

Department of Human Anatomy and Cell Science, The Children's Hospital Research Institute of Manitoba (CHRIM), Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, Canada.

Cerebellar nuclei (CN) neurons serve as the primary output of the cerebellum and originate from the cerebellar primordium at early stages of cerebellar development. These neurons are diverse, integrating information from the cerebellar cortex and relaying it to various brain regions. Employing various methodologies, we have characterized a specific subset of CN neurons that do not originate from the rhombic lip or ventricular zone of the cerebellar primordium.

Department of Nursing, Faculty of Applied Health Sciences, Brock University, St. Catharines, Ontario, Canada.

Introduction: Patient and care partner engagement in research (PER) is important in generating knowledge to improve healthcare. Arts-based methods (ABM) use art in the research process to share aesthetic knowledge, which is knowledge that may be too complex to share only verbally. Together, PER and ABM are potentially synergistic, as both are participatory, problem-focused, dialogic, and collaborative; yet little is known of the utility of ABM for PER.

Article Synopsis
  • Concussions are increasingly recognized as a serious health issue, with the need to better understand minor traumatic brain injuries (mTBI) and their long-term effects like second impact syndrome and chronic traumatic encephalopathy (CTE).
  • Current diagnostic methods for concussions primarily rely on subjective assessments, which can lead to uncertainties in diagnosis despite some assistance from neurocognitive tests.
  • Emerging research is focusing on developing objective diagnostic tools, such as specific biomarkers and advanced imaging techniques, to improve the accuracy of concussion diagnosis and management.

Background: The Abdominal Compartment Society (WSACS) established consensus definitions and recommendations for the management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in 2006, and they were last updated in 2013. The WSACS conducted an international survey between 2022 and 2023 to seek the agreement of healthcare practitioners (HCPs) worldwide on current and new candidate statements that may be used for future guidelines.

Methods: A self-administered, online cross-sectional survey was conducted under the auspices of the WSACS to assess the level of agreement among HCPs over current and new candidate statements.

The Role of Retinoic-Acid-Related Orphan Receptor (RORs) in Cellular Homeostasis.

Int J Mol Sci

October 2024

Department of Physiology and Pathophysiology, Rady College of Medicine, Max Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, MB R2H 2A6, Canada.

Retinoic-acid-related orphan receptors (RORs) are transcription factors belonging to the nuclear receptor subfamily consisting of RORα, RORβ, and RORγ. By binding to the ROR response elements (ROREs) on target gene promoters, RORs regulate a wide variety of cellular processes, including autophagy, mitophagy, oxidative stress, and inflammation. The regulatory roles of RORs are observed in cardiac cells, hepatocytes, pulmonary epithelial cells, renal cells, immune cells, and cancer cells.

Background/objectives: Acute myeloid leukemia (AML) is characterized by therapeutic failure and long-term risk for disease relapses. As several therapeutic targets participate in networks, they can rewire to eventually evade single-target drugs. Hence, multi-targeting approaches are considered on the expectation that interference with many different components could synergistically hinder activation of alternative pathways and demolish the network one-off, leading to complete disease remission.
