Glaucoma, the world's leading cause of irreversible blindness, is a condition for which elevated intraocular pressure is currently the only modifiable risk factor. However, the disorder can continue to progress even at reduced intraocular pressure. This indicates additional key factors that contribute to the etiopathogenesis. Read More

Evaluation of levels of interleukin-6, interleukin-8 and some haematologic parameters of dogs with cutaneous wounds.

Cytokine 2019 Jan 28;113:128-138. Epub 2018 Jun 28.

Department of Veterinary Medicine, ABU, Zaria, Nigeria.

The aim of the study was to investigate the time-course of serum and wound fluids interleukin (IL)-6 and IL-8 levels in dogs with cutaneous wounds and their relationship with some haematologic parameters. The experimental group comprised of six adult dogs that underwent surgery with wounds (n = 6) on the mid lateral aspect of the right antebrachium; and control group of six, apparently, healthy intact (free from cutaneous wounds) adult dogs, comprising equal number of both sexes. Vital signs evaluated were within normal limits. Read More

Peripheral oxytocin and vasopressin modulates regional brain activity differently in men and women with schizophrenia.

Schizophr Res 2018 Dec 6;202:173-179. Epub 2018 Jul 6.

Department of Radiology, West China Hospital of Sichuan University, Chengdu, People's Republic of China; Department of Psychiatry, University of Texas Southwestern Medical Center, Dallas, TX, United States of America; Department of Psychiatry, University of Cincinnati, United States of America.

Background: Oxytocin (OT) and arginine vasopressin (AVP) exert sexually dimorphic effects on cognition and emotion processing. Abnormalities in these hormones are observed in schizophrenia and may contribute to multiple established sex differences associated with the disorder. Here we examined sex-dependent hormone associations with resting brain activity and their clinical associations in schizophrenia patients. Read More

Hippocampal volume and vasculature before and after exercise in treatment-resistant schizophrenia.

Schizophr Res 2018 Dec 29;202:158-165. Epub 2018 Jun 29.

Department of Radiology, University of British Columbia, Canada. Electronic address:

Background: Schizophrenia is associated with poor cognitive function and elevated cardiometabolic disease risk. These health concerns may exacerbate neurocognitive dysfunction associated with hippocampal abnormalities, particularly hippocampal volume reductions. Regular exercise is thought to improve symptom severity, reduce depression, and improve cognition in schizophrenia, and may trigger exercise-mediated hippocampal growth. Read More

Cardiac magnetic resonance T1 mapping. Part 2: Diagnostic potential and applications.

Eur J Radiol 2018 Dec 21;109:235-247. Epub 2018 Oct 21.

Division of General Radiology, Department of Radiology, Medical University of Graz, Auenbruggerplatz 19/P, 8036 Graz, Austria; Research & Development, Siemens Healthcare Diagnostics GmbH, Strassgangerstrasse 315, 8054 Graz, Austria. Electronic address:

Non-invasive identification and differentiation of myocardial diseases represents the primary objectives of cardiac magnetic resonance (CMR) longitudinal relaxation time (T1) and extracellular volume (ECV) mapping. Given the fact that myocardial T1 and ECV values overlap throughout and within left ventricular phenotypes, a central issue to be addressed is whether and to what extent myocardial T1 and ECV mapping provides additional or superior diagnostic information to standard CMR imaging, and whether native T1 mapping could be employed as a non-contrast alternative to late gadolinium enhancement (LE) imaging. The present review aims to summarize physiological and pathophysiological alterations in native T1 and ECV values and summarized myocardial T1 and ECV alterations associated with cardiac diseases to support the translation of research findings into routine CMR imaging.
