Department of Pain Pharmacology, Institute of Pharmacology, Polish Academy of Sciences, Kraków, Poland. Electronic address:

Background: The G protein-coupled receptor 35 (GPR35), is considered important for nociceptive transmission, as suggested by accumulating evidence. This receptor was discovered in 1998; however, a lack of pharmacological tools prevented a complete understanding of its function and how to exploit it therapeutically. We studied the influence of CXCL17, kynurenic acid and zaprinast on nociceptive transmission in naïve and neuropathic mice. Read More

Extended Duration of Hyperglycemia Result in Human-Like Corneal Nerve Lesions in Mice With Alloxan- and Streptozotocin-Induced Type 1 Diabetes.

Invest Ophthalmol Vis Sci 2018 Dec;59(15):5868-5875

Laboratory of Pathology, Faculty of Pharmaceutical Science, Setsunan University, Osaka, Japan.

Purpose: Previous experimental studies assessing corneal nerves as a measure of the severity of diabetic peripheral neuropathy have yielded discordant results; this may have been due to the effect of the short duration of the induced diabetes. We investigated whether increases in the duration of hyperglycemia result in the development of corneal lesions in a mouse model of alloxan (AL)- or streptozotocin (STZ)-induced type 1 diabetes. We further determined whether corneal nerve fiber density, intraepidermal nerve fiber density (IENFD), and sural nerve morphology can be used as morphologic markers of diabetic peripheral neuropathy in rodent models.

Proton Relays in Molecular Catalysis of Electrochemical Reactions.

Angew Chem Int Ed Engl 2018 Dec 13. Epub 2018 Dec 13.

Universite Paris Diderot, Chemistry, 15 rue Jean de Baif, 75013, Paris, FRANCE.

In the current development of homogeneous catalysis of electrochemical reactions, related to contemporary renewable energy challenges, catalytic reaction schemes often involves proton coupled electron transfer sequences. The proton source (or sink) may then be an acid (or a base) present in the solution acting as a cosubstrate participating stoichiometrically and kinetically to the catalytic process. On this ground, the idea has soon emerged that installing the proton donor (for reductions, or acceptor for oxidations) inside the catalyst molecule should be beneficial in terms of efficiency, since it would then be closer to the nerve center of the process (usually the metal in the case of transition metal complex catalysts).

The two patients complained of dyspnea. Chest computed tomography showed mild pericardial effusion and thickened pericardium, which was found enveloping the heart without any lumps. Read More

Initial Japanese experience and long-term follow-up with a new active fixation coronary sinus lead, the StarFix 4195.

J Cardiol Cases 2010 Jun 27;1(3):e176-e179. Epub 2010 Jan 27.

Division of Cardiology, Department of Integrated Medicine and Informatics, Ehime University Graduate School of Medicine, Shitsukawa, Toon, Ehime 791-0295, Japan.

Technologies associated with cardiac resynchronization therapy (CRT) devices and lead systems have progressed. However, dislocation after coronary sinus (CS) lead placement continues to be a problem. Furthermore, CS lead positioning at the site of the ventricular latest activation (detected by echocardiography) is often problematic due to large vessel size leading to the lead placement (wedge site) near the apical site.

TrkB Regulates N-Methyl-D-Aspartate Receptor Signaling by Uncoupling and Recruiting the Brain-Specific Guanine Nucleotide Exchange Factor, RasGrf1.

J Mol Neurosci 2018 Dec 13. Epub 2018 Dec 13.

Department of Biochemistry, Western University, Medical Sciences Building, Rm 342, 1151 Richmond St. North, London, ON, N6A 5C1, Canada.

Brain-derived neurotrophic factor (BDNF) facilitates multiple aspects of neuronal differentiation and cellular physiology by activating the high-affinity receptor tyrosine kinase, TrkB. While it is known that both BDNF and TrkB modulate cellular processes involved in learning and memory, exactly how TrkB cross-talks and modulates signaling downstream of excitatory ionotropic receptors, such as the NMDA receptor (NMDAR), are not well understood. A model that we have investigated involves the signaling molecule RasGrf1, a guanine nucleotide exchange factor for both Ras and Rac. Read More

Nerve grafting for peripheral nerve injuries with extended defect sizes.

Wien Med Wochenschr 2018 Dec 13. Epub 2018 Dec 13.

Department of Plastic and Reconstructive Surgery, Medical University of Vienna, Währinger Gürtel 18-20, 1090, Vienna, Austria.

Artificial and non-artificial nerve grafts are the gold standard in peripheral nerve reconstruction in cases with extensive loss of nerve tissue, particularly where a direct end-to-end suture or an autologous nerve graft is inauspicious. Different materials are marketed and approved by the US Food and Drug Administration (FDA) for peripheral nerve graft reconstruction. The most frequently used materials are collagen and poly(DL-lactide-ε-caprolactone). Read More

Interferon-α-induced retinopathy in chronic hepatitis C treatment: summary, considerations, and recommendations.

Graefes Arch Clin Exp Ophthalmol 2018 Dec 13. Epub 2018 Dec 13.

Interferons are cytokines that regulate the host's response to viral infection, particularly in the setting of the immunologic response to the hepatitis C virus (HCV). While the virus has the ability to evade the host's innate and specific immunity, exogenous interferon-α with combined ribavirin, treatments have been found to achieve a significant sustained viral response in subgroups of patients with chronic HCV. One of the major side effects of interferon-α is an ocular retinopathy characterized by flame-shaped hemorrhages and cotton wool spots visualized on funduscopic examination. Read More
