Characterizing the clinical implementation of a novel activation-repolarization metric to identify targets for catheter ablation of ventricular tachycardias using computational models.

Comput Biol Med 2019 Mar 23;108:263-275. Epub 2019 Mar 23.

School of Biomedical Engineering and Imaging Sciences, King's College London, London, United Kingdom. Electronic address: https://kclpure.kcl.ac.uk/portal/martin.bishop.html.

Identification of targets for catheter ablation of ventricular tachycardias (VTs) remains a significant challenge. VTs are often driven by re-entrant circuits resulting from a complex interaction between the front (activation) and tail (repolarization) of the electrical wavefront. Most mapping techniques do not take into account the tissue repolarization which may hinder the detection of ablation targets. Read More

Nitric oxide and interactions with reactive oxygen species in the development of melanoma, breast, and colon cancer: A redox signaling perspective.

Nitric Oxide 2019 Apr 19. Epub 2019 Apr 19.

New York University School of Medicine, New York, NY, USA.

Cancer development is closely related to chronic inflammation, which is associated with identifiable markers of tumor progression, such as uncontrolled cell proliferation, angiogenesis, genomic instability, chemotherapeutic resistance, and metastases. Redox processes mediated by reactive oxygen species (ROS) and nitric oxide (NO) within the inflammatory tumor microenvironment play an essential role in directly influencing intercellular and intracellular signaling. These reactive species originating in the cancer cell or its microenvironment, mediate the epithelial-mesenchymal transition (EMT) and the mesenchymal-epithelial transition (MET). Read More

Differential expression patterns of sodium potassium ATPase alpha and beta subunit isoforms in mouse brain during postnatal development.

Neurochem Int 2019 Apr 19. Epub 2019 Apr 19.

Ruhr University Bochum, Faculty of Chemistry and Biochemistry, Biochemistry II, Bochum, Germany; Ruhr University Bochum, International Graduate School for Neuroscience, Germany. Electronic address:

The sodium potassium ATPase (Na/K ATPase) is essential for the maintenance of a low intracellular Na and a high intracellular K concentration. Loss of function of the Na/K ATPase due to mutations in Na/K ATPase genes, anoxic conditions, depletion of ATP or inhibition of the Na/K ATPase function using cardiac glycosides such as digitalis, causes a depolarization of the resting membrane potential. While in non-excitable cells, the uptake of glucose and amino acids is decreased if the function of the Na/K ATPase is compromised, in excitable cells the symptoms range from local hyper-excitability to inactivating depolarization.

Knockout of adenylyl cyclase isoform 5 or 6 differentially modifies the β-adrenoceptor-mediated inotropic response.

J Mol Cell Cardiol 2019 Apr 19. Epub 2019 Apr 19.

Faculty of Medicine, Department of Pharmacology, Center for Heart Failure Research, Oslo University Hospital, University of Oslo, Oslo, Norway.

Although only β-adrenergic receptors (βAR) dually couple with stimulatory G protein (G) and inhibitory G protein (G), inactivation of G enhances both βAR and βAR responsiveness. We hypothesize that G restrains spontaneous adenylyl cyclase (AC) activity independent of receptor activation. Subcellular localization of the AC5/6 subtypes varies contributing to the compartmentation of βAR signaling. Read More

Departments of Pediatrics, Neurology and Neurotherapeutics, University of Texas Southwestern Medical Center at Dallas and Children's Health Dallas (M.M.D.).

Background and Purpose- Sickle cell disease (SCD) and arteriopathy are pediatric stroke risk factors that are not mutually exclusive. The relative contributions of sickled red blood cells and arteriopathy to stroke risk are unknown, resulting in unclear guidelines for primary and secondary stroke prevention when both risk factors are present. We hypothesized that despite similarities in clinical presentation and radiographic appearance of arteriopathies, stroke evaluation and management differ in children with SCD compared with those without SCD.

Evaluating the Impact of Variable Phosphorothioate Content in Tricyclo-DNA Antisense Oligonucleotides in a Duchenne Muscular Dystrophy Mouse Model.

Nucleic Acid Ther 2019 Apr 22. Epub 2019 Apr 22.

1 Université de Versailles St- Quentin, U1179 INSERM, UFR des Sciences de la Santé, Montigny le Bretonneux, France.

Antisense oligonucleotides (ASOs) hold promise for therapeutic splice switching correction for genetic diseases, in particular for Duchenne muscular dystrophy (DMD), for which ASO-exon skipping represents one of the most advanced therapeutic strategies. We have previously reported the therapeutic potential of tricyclo-DNA (tcDNA) in mouse models of DMD, highlighting the unique pharmaceutical properties and unprecedented uptake in many tissues after systemic delivery, including the heart and central nervous system. TcDNA-ASOs demonstrate an encouraging safety profile and no particular class-related toxicity, however, when administered in high doses for several months, mild renal toxicity is observed secondary to predictable phosphorothioate (PS)-ASO accumulation in kidneys.

The need of developing selective prediction models in elderly patients with heart failure.

Int J Clin Pract 2019 Apr 22:e13354. Epub 2019 Apr 22.

IRCCS Ospedale Policlinico San Martino Genoa, 10 largo Benzi, 16132, Genoa, Italy.

It is with great interest that we have read the article by Özlek and co-workers, who performed a post-hoc analysis of results from the APOLLON trial (A comPrehensive, ObserationaL registry of heart faiLure with mid-range and preserved ejection fractiON). The authors investigated in a real-world study (patients included in a registry) the effects of treatment of octogenarian individuals with heart failure (HF) with mid-range and preserved ejection fraction, and then, the authors compared the observation in elderly to younger subjects. Interestingly, the authors reported that elderly patients with HF were similarly treated as compared to younger patients (in terms of ACE-Is/ARBs, β-blockers, MRAs, digoxin, ivabradine and diuretics), thus suggesting adherence to guideline recommendations independently of the age of subjects.

Melatonin Stabilizes Rupture-Prone Vulnerable Plaques via Regulating Macrophage Polarization in a Nuclear Circadian Receptor RORα-Dependent Manner.

J Pineal Res 2019 Apr 22:e12581. Epub 2019 Apr 22.

State Key Laboratory for Oncogenes and Related Genes, Division of Cardiology, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai Cancer Institute, Shanghai, China.

Rupture of vulnerable plaques is the main trigger of acute cardio-cerebral vascular events, but mechanisms responsible for transforming a stable atherosclerotic into a vulnerable plaque remain largely unknown. Melatonin, an indoleamine hormone secreted by the pineal gland, plays pleiotropic roles in the cardiovascular system; however, the effect of melatonin on vulnerable plaque rupture and its underlying mechanisms remain unknown. Here, we generated a rupture-prone vulnerable carotid plaque model induced by endogenous renovascular hypertension combined with low shear stress in hypercholesterolemic ApoE mice. Read More

Multivariate analyses reveal biological components related to neuronal signaling and immunity mediating EEG abnormalities in alcohol-dependent individuals from the COGA cohort.

Alcohol Clin Exp Res 2019 Apr 22. Epub 2019 Apr 22.

Olin Neuropsychiatry Research Center, Hartford Hospital/IOL, Hartford, CT, 06107.

Background: The underlying molecular mechanisms associated with alcohol use disorder (AUD) risk have only been partially revealed using traditional approaches such as univariate GWAS and linkage-based analyses. We therefore aimed to identify gene clusters related to EEG neurobiological phenotypes distinctive to individuals with AUD using a multivariate approach.

Methods: The current project adopted a bi-multivariate data-driven approach, parallel independent component analysis (para-ICA) to derive and explore significant genotype-phenotype associations in a case-control subset of the Collaborative Study on the Genetics of Alcoholism (COGA) dataset.

Effects of pulsed inhaled nitric oxide on arterial oxygenation during mechanical ventilation in anaesthetised horses undergoing elective arthroscopy or emergency colic surgery.

Equine Vet J 2019 Apr 22. Epub 2019 Apr 22.

Department of Clinical Sciences, Faculty of Veterinary Medicine and Animal Science, Swedish University of Agricultural Sciences, Uppsala, Sweden.

Background: Administration of pulsed inhaled nitric oxide (PiNO) improves arterial oxygenation in spontaneously breathing anaesthetised healthy horses and in horses undergoing colic surgery. However, because hypoventilation commonly occurs, horses are often mechanically ventilated to prevent hypercarbia.

Objectives: To evaluate the effects of PiNO on arterial oxygenation during anaesthesia in mechanically ventilated healthy horses and horses undergoing colic surgery. Read More
