Activation of tyrosine phosphatase PTP1B in pyramidal neurons impairs endocannabinoid signaling by tyrosine receptor kinase trkB and causes schizophrenia-like behaviors in mice.

Neuropsychopharmacology 2020 Jul 1. Epub 2020 Jul 1.

Ottawa Hospital Research Institute, Neuroscience, University of Ottawa Brain and Mind Institute, Ottawa, ON, K1H 8M5, Canada.

Schizophrenia is a debilitating disorder affecting young adults displaying symptoms of cognitive impairment, anxiety, and early social isolation prior to episodes of auditory hallucinations. Cannabis use has been tied to schizophrenia-like symptoms, indicating that dysregulated endogenous cannabinoid signaling may be causally linked to schizophrenia. Previously, we reported that glutamatergic neuron-selective ablation of Lmo4, an endogenous inhibitor of the tyrosine phosphatase PTP1B, impairs endocannabinoid (eCB) production from the metabotropic glutamate receptor mGluR5.

Bioprosthetic Valve Fracture for Early Severe Prosthesis Mismatch After SAVR.

J Invasive Cardiol 2020 Jul;32(7):E182-E185

Sentara Heart Valve and Structural Disease Center, Sentara Heart Hospital, 600 Gresham Drive, Norfolk, VA 23507 USA.

Background: Patient prosthesis mismatch (PPM) is an iatrogenic complication that occurs in patients who undergo surgical aortic valve replacement (SAVR). PPM occurs when the implanted surgical valve has an effective orifice area (EOA) that is too small for the patient, resulting in a gradient across the valve despite an otherwise normally functioning prosthesis. PPM has been associated with mid- and long-term increased morbidity and mortality. Read More

Frontier Science Research Center, University of Miyazaki Faculty of Medicine, Cardiovascular Medicine, University of Miyazaki Hospital, 5200 Kihara, Kiyotake, Miyazaki 889-1692, Japan. Electronic address:

The family of natriuretic peptides (NPs) discovered in mammalian tissues including cardiac atrium and brain consists of three members, namely, atrial, B- and C-type natriuretic peptides (ANP, BNP, CNP). Since the discovery, basic and clinical studies have been vigorously performed to explore the biological functions and pathophysiological roles of NPs in a wide range of diseases including hypertension and heart failure. These studies revealed that ANP and BNP are hormones secreted from the heart into the blood stream in response to pre- or after-load, counteracting blood pressure (BP) elevation and fluid retention through specific receptors.

Department of Dermatology, Guang'anmen Hospital, China Academy of Chinese Medical Sciences, Beijing 100053, China.

Psoriasis Vulgaris (PV) not only affects patients' skin health but also increases the risk of coronary heart disease and diabetes, which brings both physical and mental harms. Its pathogenesis is complex, and the multi-target effect of traditional Chinese medicine (TCM) is especially advantageous. Because a considerable number of randomized controlled trials related to TCM exhibit design defects, small sample size or inadequate intervention time, so the status of TCM in the treatment of PV cannot be fully clarified.

Functional reservoir microcapsules generated via microfluidic fabrication for long-term cardiovascular therapeutics.

Department of Biomedical Engineering, City University of Hong Kong, 83 Tat Chee Avenue, Kowloon Tong, Hong Kong, China.

Cardiovascular disease is a chronic disease that leads to impaired cardiac function and requires long-term management to control its progression. Despite the importance of hydrogels for therapeutic applications, a contradiction between the size of a hydrogel and the amount of loaded drug has been encountered when using conventional fabrication methods. In this study, biocompatible reservoir microcapsules (diameter ∼100 μm) with a large liquid core and polymeric shell were fabricated via a one-step phase separation of poly(ethylene glycol)diacrylate (PEGDA) and dextran within pre-gel droplets through microfluidics.

Pulmonary hypertension (PH) is a disease characterized by progressive rise of pulmonary artery (PA) pressure, which can lead to right ventricular (RV) failure. It is usually diagnosed late because of the nonspecificity of its symptoms. RV performance and adaptation to an increased afterload, reflecting the interaction of the PA and RV as a morphofunctional unit, constitute a critical determinant of morbidity and mortality in these patients.

Long term use of donepezil and QTc prolongation.

Clin Toxicol (Phila) 2020 Jul 1:1-7. Epub 2020 Jul 1.

Department of Cardiology and Internal Medicine, Wexham Park Hospital, Frimley Health NHS Foundation Trust, Slough, UK.

The neurocognitive benefits of donepezil are well recognised, but the potential side effects on cardiac conduction remain unclear. To investigate whether long-term donepezil therapy is associated with electrocardiographic (ECG) changes and in particular to assess its effects on the QT interval. We conducted a single centre retrospective analysis of patients admitted to our trust on donepezil therapy over a 12-month period. Read More

Intrathecal injection of Brilliant Blue G, a P2X7 antagonist, attenuates the exercise pressor reflex in rats.

Am J Physiol Regul Integr Comp Physiol 2020 Jul 1. Epub 2020 Jul 1.

Heart and Vascular Institute, Penn State College of Medicine, United States.

Purinergic 2X receptors (P2X) on the endings of group III and IV afferents play a role in evoking the exercise pressor reflex. Particular attention has been paid to P2X3 receptors because their blockade in the periphery attenuated this reflex. In contrast, nothing is known about the role played by P2X receptors in the spinal cord in evoking the exercise pressor reflex in rats. Read More

Cardiovascular and metabolic responses to passive hypoxic conditioning in overweight and mildly obese individuals.

Am J Physiol Regul Integr Comp Physiol 2020 Jul 1. Epub 2020 Jul 1.

HP2 Laboratory, Grenoble Alpes University, INSERM, France.

Background: While severe intermittent hypoxia (IH) is well known to induce deleterious cardiometabolic consequences, moderate IH may induce positive effects in obese individuals. The present study aimed to evaluate the effect of two hypoxic conditioning programs on cardiovascular and metabolic health status of overweight or obese individuals.

Methods: In this randomized single-blind controlled study, 35 subjects (54±9. Read More

Uptake, accumulation and biomarkers of PM2.5-associated organophosphate flame retardants in C57BL/6 mice after chronic exposure at real environmental concentrations.

Environ Sci Technol 2020 Jul 1. Epub 2020 Jul 1.

Although the bioaccumulation of organophosphate flame retardants (OPFRs) in aquatic organisms has been investigated, little information is available about their bioaccumulation in mammals following chronic inhalation exposure. To address this knowledge gap, C57BL/6 mice were exposed to 7 PM2.5-associated OPFRs via the trachea to study their bioaccumulation, tissue distribution and urinary metabolites. Read More

Intrinsic Color Sensing System Allows for Real-Time Observable Functional Changes on Human Induced Pluripotent Stem Cell Derived Cardiomyocytes.

ACS Nano 2020 Jul 1. Epub 2020 Jul 1.

Stem-cell based in vitro differentiation for disease modeling offers great value to explore the molecular and functional underpinnings driving many types of cardiomyopathy and congenital heart diseases. Nevertheless, one major caveat in the application of in vitro differentiation of human induced pluripotent stem cell (hiPSC) derived cardiomyocytes (hiPSC-CMs) involves the immature phenotype of the CMs. Most of the existing methods need complex apparatus and require laborious procedures in order to monitor the cardiac differentiation/maturation process and often result in cell death.

Background: Brugada syndrome is a disorder associated with sudden cardiac death and characterized by an abnormal electrocardiogram (ECG). Previous studies were predominantly conducted in men, and the data on long-term prognosis are limited. Information about women, especially elderly women, is lacking. Read More
